I'm curious about how the $15k/mo figure is computed.

The story reads as though Logojoy more or less launched on Producthunt, which was 7 days ago. And all posts on the blog are dated Nov 15th. Finally the domain itself seems to have been listed on HugeDomains as of Oct 8th [1].

Now maybe I'm missing something, but it seems like the revenue figure is extrapolated from a small window which includes a wave of initial traffic from PH.

I'm hoping that the revenue figure is an actual ongoing sustained amount for Dawson's sake (as it is great looking & functioning product, solves a need that I've faced, and for full disclosure I've been putting together something along these lines on the backburner for awhile), but I can't help but feel this is a bit sensationalized based on what I'm seeing here.

> I've been a designer for 12 years or so... I would get frustrated designing logos for small businesses because (a) it was so time-consuming to create 30 mockups, (b) it would take weeks to do those small back-and-forths, and (c) the logo would end up being so simple that I felt like that entire process was a waste... As soon as I had the idea ... I started working on it.

I think this is my favorite part of the story. If you've been a designer (or any profession) for over a decade, even with frequent frustrations, it takes a certain kind of humility and introspection to realize that maybe it's not just about your customers being "broken" (by choosing the designs that take the least effort) or needing to find more sophisticated customers who value your talents.

Sometimes (ok, usually) it makes more sense to build what people really want rather than giving them what we think they should want. As a developer and entrepreneur, I have to be reminded of that fairly often.

What struck me the most is going with the old and tried tools (PHP+MySQL). Nowadays everyone - myself included - is trying to have an excuse to try the sexiest JS framework of the day and most of us fail miserably to deliver anything useful - because of lack of experience or just reinventing the wheel altogether.

Old and boring is still sometimes the best.

Its refreshing to see a startup doing well and not feeling the need to force a subscription on people.

I get that SaaS can be a good business model (great, even). On the other hand, I think subscription fatigue is real and you should think hard about your pricing. Dawson is making $15K/month on ONE TIME feesand fees that are lower than a lot of monthly SaaS plans.

I want to see more of this.

I imagine this was upvoted because of Indiehackers credibility, so people just assumed the achievement of $15k/mo was true.

Until mikejarema noticed in another comment that the product was launched 15 days ago and the title was BS, I believed too. Now I flagged the story because it is basically a lie. And IndieHackers lost a lot of its credibility for me by now.

Other people noticed the AI part is most likely BS too. But that is a less black and white lie than claiming that the creator "makes $15k/mo" when he hasn't made $15k total in the whole product lifetime.

Shame on you indiehackers for outright lying (maybe twice) in the title just to get clicks. You gamed HN for this one, but I have the impression that this will hurt you in the future.

Very impressing, hits the sweet spot for projects that need a logo but don't have a big budget. A few comments:

* I skipped picking symbols and it generated a logo with a monogram. I wanted to get rid of this so I looked in the Symbol menu and was frustrated not to find it. I eventually found it in "Layout" but that's not the first place I thought to look.

* There's a lot greyed text used on controls, which is both hard to read and makes it look like the controls are disabled. e.g. horizontal scroll buttons, uppercase/lowercase toggle, text input boxes

* Logos on the preview page load slowly/inconsistently at times, leaving the sample images blank. Perhaps use loading indicators or don't show backgrounds until logo is ready.

* reloading the page loses your work (oops)

If I could offer feedback about the pricing structure -- I think if I didn't know (from the article) that it's free to create unlimited logos, I wouldn't have figured that out by looking at your pricing section.

And I know it says "It's free to build unlimited logos. Only pay when you want to download" right there in plain text under the headline, but my eyes skipped over that part. I expected clickable price boxes too. I think it looks so similar to a typical SaaS pricing page that I assumed it works the same way. I don't know how best to fix it, but it might be worth testing different arrangements to make it clearer that it's free to sign up and create a logo.

I'm happy this guy built something that's generating income, but the results of my attempt to use it just now were really underwhelming. Page after page of COMAPANY NAME on plain cards with different fonts didn't really demonstrate much AI. My takeaway here is that this "story" is not yet a story. Maybe 1-2 years from now, after the product has really developed and evolved, it will be something.

If you're still reading this: could you please allow + in the e-mail address?

I understand why you want me to sign up, but I have no idea how much e-mail you're going to decide to send me, and sending it to a plus-address allows me to filter it on my terms.

There's really no reason not to allow the + sign, unless you're going to do something nefarious with my e-mail address and you don't want me to know it was you.

You should expand to recreational sports teams. The logos all follow similar formats and everyone wants one that looks professional but on a limited budget. There are design services that will do it manually but your algorithm approach would work really well for it as well.

Good site, scary site, good because it does a great job at creating a simple logo. I suspect that it can cover the majority of the small companies that want a logo. It certainly does a good job. I tried and created a pretty good one.

I've used other similar sites but they've all been created by a team of programmers and system/network administrators over a few years.

Scary because it brings into focus how easy it is to replace what could be considered a somewhat complicated job. Yes, it can't replace all graphic designers but it magnifies the power of a few by a large factor. In this case, just one motivated individual.

Edit: changed bad to scary, fits better with my thinking, and fixed typos

Really impressive!

I feel there's still so many ideas to make a business around if you base it on ML/AI. Being early here could potentially net a huge passive income. Personally I have an idea in mind, and I'm still learning ML slowly on the side. In my eyes this is the true way to independence from "the system" for people who put in enough effort and who have enough knowledge.

Why do we not see more of this yet? Is the combination of people who know machine learning, and people who are entrepeneurs so narrow?

Some feedback:

I love the UX/UI - but I cant tell it where to put the color/font selections and it only previews with "COMPANY NAME" instead of actually updating with the company name and slogan that you asked me for in the beginning on the selection process...

So - I don't know if I like the selection based on that because I wanted the reverse of what it offered (I wanted orange letters with grey background - but it only gives me orange bkgd with grey letters...

I would also like a bit better control over the location of the icon.

The "saved logo" update pop-up is confusing as when I go back to logo - it doesn't always hold the design I selected...

Otherwise this is impressive and awesome... I'd like to use it.

Just to be clear: This service is offered by Amazon/AWS themselves, it isn't a third party. That's a question I had when I first clicked, which is why I am answering it here.

One big "gotcha" for AWS newbies which I cannot tell if this addresses: Does this set or allow the user to set a cost ceiling?

AWS have offered billing alerts since forever. They'll also occasionally refund unexpected expenses (one time thing). But they've never offered a hard "suspend my account" ceiling that a lot of people with limited budgets have asked for.

They claim this is a competitor for Digital Ocean, but with DO what they say they charge is what they actually charge. I'm already seeing looking through the FAQ various ways for this to exceed the supposed monthly charges listed on the homepage (and no way to stop that).

Why even offer a service like this if you cannot GUARANTEE that the $5 they say they charge is all you'll ever get charged? How is this different from AWS if a $5 VPS can cost $50, or $500?

That's what Amazon is missing. People want ironclad guarantees about how much this can cost under any and all circumstances. I'd welcome an account suspend instead of bill shock.

Let me get this straight, right now AWS is billing me $270/mo for 3TB of bandwidth on my autoscaling web servers. With LightSail, I can get that same bandwidth, plus storage and instances for $15/mo?

In total, I'm spending about $15,000/yr on AWS, and someone spending $5/mo gets their bandwidth 18x cheaper than me? Shouldn't it be the other way around, and I should be the one with the discount?

I get enough headaches dealing with reserved instances, and trying to buy them at the correct time of the year to line up with price drops. Now, I need to consider dumping my autoscaling groups, EC2 web servers, and moving them to LightSail? Why not just give us a fair price on bandwidth, instead of more complications?

A compelling product. The dashboard looks great. They even replaced the confusing term "user data" with "launch script", but they fall back into it later. SSH in-browser is great too and can be bookmarked/opened in a fullscreen tab. Uploading (instead of pasting) your SSH pubkey is a bit annoying.

The docs appear to say you can add these to a VPC but I don't see how to do it.

They don't say the SSD storage is local, so I'm sure it's not.

A few runs with `fio` confirms this is EBS GP2 or slower:

The bench: "fio --name=randrw --ioengine=libaio --direct=1 --bs=4k --iodepth=64 --size=4G --rw=randrw --rwmixread=75 --gtod_reduce=1"

Lightsail $5:

 read : io=3071.7MB, bw=9199.7KB/s, iops=2299, runt=341902msec write: io=1024.4MB, bw=3067.1KB/s, iops=766, runt=341902msec
DigitalOcean $5:

 read : io=3071.7MB, bw=242700KB/s, iops=60674, runt= 12960msec write: io=1024.4MB, bw=80935KB/s, iops=20233, runt= 12960msec
More than an order of magnitude difference in the storage subsystems.

These appear to just be t2.nano instances (CPU perf is good, E5-2676 v3 @ 2.40 GHz, http://browser.primatelabs.com/geekbench3/8164581).

For advanced users, there isn't much compelling here to make up for the administration overhead. It's a little cheaper than a similar-spec t2.nano (roughly $4.75 on-demand + $3 for a 30GB SSD). The real win is egress cost; you can transfer EC2->Lightsail for free. 1TB of egress would be nearly $90 on EC2, but is only $5 on Lightsail.

In other news, EC2 egress pricing is obviously ridiculous.

This is a non-starter without IPv6. I know some of you will be tempted to jump ship from DO and Vultr, but please remember that by doing so you will continue enabling Amazon to hold back progress. While ignoring AWS is not really an option, as it offers some very unique features that are quite useful, this thing does not.

DO is not great in this regard as their butcher their allocations, but Vultr gives each VPS a proper /64. Scaleway has partial IPv6 support (not for their bare metal could, but their VPS's do support it).

I urge you to vote with your wallets, unless you really like paying $1/month or more per IP for the foreseeable future.

Here is a comparison of $20 instances across DO, Linode and LightSail

All have 3TB transfer

Linode(Best): 4GB RAM, 2 Core, 48 GB SSD

DO: 2GB RAM, 2 Core, 40 GB SSD

LightSail(Worst): 2GB RAM, 1 Core, 40 GB SSD

I use this exact instance on Linode for my site https://dictanote.co; that one extra core makes a lot of difference when you want to take a backup of db or something intensive like that.

Is there anything preventing me from using these servers as proxies with incredibly cheap bandwidth? I assume it stacks? When we reach transfer limits I can just spin up an additional $5 instance to add another 1TB?

$5/mo per 1TB of bandwidth = $5.00 / 1024 = $0.0049/GB compared to EC2's normal $0.09/GB -- That's a 91-95% discount on egress data!

The major reason to use a VPS host instead of AWS is that AWS is complicated. This seems to be just as simple as DO or a million other VPS hosts, with the added benefit that it's easy to hook up to Amazon's other services if you need to.

It just dumps you into a revamped, less intimidating AWS console so I wouldn't be too concerned about this for now.

The thing that keeps me away from AWS services is the depth of the service - I need to be an expert in AWS on top of knowing how to configure my servers, which for now is maybe a non starter.

It does show you the power of packaging: with a simple domain and thrown together marketing page, you too can target another market segment.

It's funny to me that Amazon has looped all the way back around to this, while a bunch of smaller providers who've been doing this for over a decade have been trying to catch up with AWS on all the other fronts. But, realistically, for a lot of users, AWS is a stupidly complex beast just to get a website up and running. I've written a bunch of code that interacts with AWS APIs in two languages, and I still require a couple of hours to spin up anything new there.

But, as others note, the variable cost factor seems to still be a sticking point. I can setup a Digital Ocean droplet, or Linode, or one of a dozen other low-cost VPS providers, for $5 or $10 a month, and I know it will never cost more than that. Maybe I'll bump into memory, disk, or bandwidth limits...but, AWS is a killer if you aren't careful. I used to maintain (and pay for, out of pocket) a non-profit's website on AWS, and the price ballooned while I wasn't paying attention, due to automated backups to S3 and some other stuff, and by the time I noticed was costing me $183/month, for a website that could easily run on a cheap VPS. My fault for not paying closer attention, not setting up cost alerts, etc., but I moved the site off of AWS and onto one of my own web servers, where it literally costs me single digit dollars to run (it has many GBs of email but otherwise is a small site with very low traffic).

So...unless they're giving me some reason to think I won't end up with a massive bill one month because of a popular post, or something, I probably still won't think "I know, I'll use AWS!", unless it's a situation where I need the scaling capabilities of AWS.

My guess is Amazon wants to rope people into their ecosystem, and they've recognized that many startups have opted for the cheaper VPS providers in their bootstrap days.

This is an intriguing move and one that I'm sure DigitalOcean, Linode, and Vultr have been fearing may happen.

The pricing is on par with these alternatives in the VPS space.

A quick look at the pricing shows these are plagued by the same problems as DO's offerings: only RAM scales linearly with price, while CPU, storage, and data transfer do not.

Linode and OVH, while not as prestigious as AWS and DO, offer much more fair pricing when you need more resources.

When I started out webdev, I was told that I should use AWS. But not having known how private/pubkeys work, or how ssh workds, how servers worked, it felt a lot like being thrown in the deep end of the pool.

Then I used digitalocean because of the free 1 year server time github gave me and everything was a breeze. They had tutorials for a lot of stuff, like how pubkeys and privatekeys worked, how to use ssh, how a server works, how to use nginx/apache, and even node.js stuff. I got up and running quickly even though it was my first time using a VPS. It was super easy, and the best part was with my knowledge gained from DigitalOcean, I was able to start using AWS with relative ease.

I think Lightsail is a good competitor to DigitalOcean, good for newbies who can't exactly figure out how much their server will use and charge them. But imo, with the same stats and stuff as DigitalOcean as a newbie I'd stick with DigitalOcean just because of how helpful their tutorials are in general and how helpful their interface is.

I feel as excited as I was for Azure's Build 2016. Now I'm feeling pulled to AWS. This is great for AWS, not so much for Google Cloud which further fades into obscurity in my mind. I'd love to see that change, more competition in the cloud space = more options for us developers = more conditions in our favour.

Amazon LightSail just killed digitalocean for me which has been steadily getting more expensive (for instance I can't downsize to a less expensive plan once I resize my image, meaning I forked out $100/month for something that would work for $5/month + multiple DO images now cost monthly fee.

$5/month + tight integration with AWS products is enough for me to move completely off DO. If only AWS had DO's community style documentation, I'd definitely question DO's future viability.

Now a killer IDE from AWS that lets me deploy and configure AWS without leaving the IDE, that's a checkmate move, which I think will be very difficult for me to switch to another cloud provider. Right now things are in flux but I think an in-browser/desktop IDE like Cloud 9 with one click deploy to AWS would be the end game for other cloud providers.

Keep in mind if you are a current EC2 customer and are excited about a cheaper VPS in your region, the VPSs are only available in Virginia. I was pretty excited about a cheaper VPS I could provision in the Sydney area, but these are restricted to a single datacenter.

What I was hoping for was a bare-metal (not-run through VMs) container runtime like Joyent Triton[0] but with more pay-for-what-you-use pricing.

Unlike VMs, which statically allocate mem whether you use it or not, containers have the chance to grow and reduce mem as workfloads go up and down, which means you could pay for GB/h of mem usage on the right-sized # of vCPU base.

Not sure if any IaaS/PaaS is doing this.

Joyent pricing[1] is still for static resource allocation and not cheap compared to these larger players.

This is very appealing to me just because of the amount of bandwidth that is included. I currently serve 20TB/month of static assets for only $160 spread among Softlayer, Digital Ocean and Linode VPSs. If I can host my static assets on the same network as AWS for the same price then that is a huge win, especially since all new Softlayer VPSs only come with a measly amount of bandwidth.

I just created two 512MB Ubuntu instances and here are my thoughts. (+ indicates positive, - indicates negative, ? question)

 + You can use private networking for cross-instance communication. + You can even communicate with other AWS services by using VPC peering. + Hourly billing. - The firewall rules are not shared. You can't create a single rule and attach to multiple instances. ? What are the network throughput caps? Can't find it anywhere? ? Are the disk physical or using EBS? ? Can you snapshot a running instance, or does it have to stopped?

I don't understand why everybody on this thread is complaining about overages? If you use more than the allocated amount you pay overages, simple idea. Why in the world, would you want your server to just shut down when you reach a limit?

Interesting. Pricing is worse than Digital Ocean here. Looks like Linode is still best bang for buck strictly for price to power.

Random thoughts from shameless noob:

- I like Digital Ocean's OS/app images for speed / smaller projects. Looks like Lightsail offers this with Bitnami. Not sure how complicated that is in their console.

- Amazon IAM comes with a bit too much overhead for noobies like myself. Glad this doesn't require you to set that up when you just want a quick and dirty VPS.

- Bah. Resizing/upgrading requires you to do it through API currently. That kind of sucks.

- Nice! 30 day free trial.

The FAQ is extremely unclear, but if I'm understanding it right, doesn't this make transfer out to Internet significantly cheaper if you insist on using AWS? Instead of paying $0.09/GB, transfer to Lightsail for $0.02/GB then transfer out for $5/1000 GB=$0.005/GB. You do have to deal with changing IP, but you get a 1.26 order of magnitude decrease in price, and that's assuming you don't bother actually using the extra compute.

Nice: a much needed simplification of the AWS product surface area. While their plethora of functions and features are tremendously useful for big shops, but are a pretty high bar newer entrants.

Now if they could just get to the point where $5 gets you a running Docker container running on the equivalent of the Lightsail VPS (without setting up the backing EC2 infrastructure like ECS), I suspect that's closer to the platform that many users really want to have ...

This seems like a great option for a utility server for existing AWS customers. With VPC peering you get free and fast transfer between one of these and your existing AWS infrastructure, but in a nice one-price VPS.

I also wouldn't be too surprised to see some people using these as middle-man boxes to reduce transfer costs associated with EC2 - $5 for 1TB is darned cheap for AWS. Using one of these to back up data from some EC2 hosts would be a win.

Quick feedback for the AWS team:

* First, this is great. The simplified interface vs EC2 is terrific. This is the direction EC2 (and RDS and S3 and basically everything) needs to be going.

* Instances you start in LightSail don't show up in your EC2 console. I would expect there to be some kind of data sharing there.

* Similarly, creating a "static IP address" doesn't show up in your elastic IP list. I'm not sure if this is intentional, but to manage two different views of products that you're billing me for is... troublesome.

* Last, if I could migrate elastic IPs from EC2 to LightSail I'd be migrating all of my instances immediately. The bandwidth savings are massive. (Related: when is the 2TB limit for a t2.small going to be migrated over to EC2?)

Hopefully Google Computer Engine will also compete at this price now.

I use AWS for a bunch of things, but the console has always been immensely painful to use, especially to create a no frills simple VPS for a fiver. For that reason alone, I use DigitalOcean and fiddle with AWS authentication if I need to use some of its services there.

Lightsail looks excellent since the setup is just a gazillion times more user friendly than the standard EC2. A single page affair, a launch script, authentication, it's all there. Once launched, I get all the info and metrics I need.

I kinda wish they streamlined their usual console to this level, but this way it's fine as well. I don't tend to use S3 and EC2 as much as I'd like given its non-existent UX, but this gives me hope that Amazon is taking user experience seriously.

Sure, it may be underpowered compared to DO or Linode, but having all services under one roof is worth it to me. I'm happy.

Wow, what perfect timing. I just got approved for AWS Educate and was prepared to do the work to batch auto-provision EC2 instances for my students, but this is much easier to deal with. And at $5 a month for the cheapest machine, it's about what I would have paid to set up a t2-nano instance (~$4.70). I didn't need anything fancy, just wanted students to have their own machine to deploy public-facing code (e.g. APIs).

The in-browser SSH also deals with the problem of students who are on Windows machine. You haven't hated PuTTY until you've tried walking a student through it on their Surface Pro.

Confirmed that LightSail works with ServerPilot (https://serverpilot.io/).

LightSail's default firewall opens ports 22 (SSH) and 80 (HTTP) but has 443 (HTTPS) closed. That seems like a terrible default for making a developer-friendly service. Hopefully they fix that and open 443 by default. Otherwise, a lot of wasted time is going to be spent by developers who have configured SSL on their sites and don't know why it isn't working.

LightSail feels very similar to DreamCompute that DreamHost launched, including the approach of only allowing SSH public key auth without any option of using password auth. So, they're intentionally leaving out some users with that approach.

Not terribly impressed. It's like Digital Ocean and Vultr but with no IPv6 and no direct network interface.

What I love about VPSes as opposed to AWS, Azure, or Google is that you get a completely a la carte box with a direct interface right to the Internet and both IPv4 and an IPv6 /64. You can instantly provision "servers" that you can do anything you want with -- you can treat them like "pets" to run a personal blog or a legacy app, or you can herd them like "cattle" with your favorite management and provisioning tools. The pricing is great and the infrastructure is mix and match.

Many VPS providers (Vultr and I think DO as well) will even let you upload and install an ISO directly onto the KVM instance over the web. That means you can install OpenBSD or even weird OSes. I've heard of people putting wacky stuff like OS/2 in the cloud this way. Some even allow nested virtualization.

A VPS is ideal for a large number of common work loads, but not all. For things where I want to make extensive use of AWS's managed services or where I want to have something more akin to a private data center, EC2 and similar offerings from Microsoft and Google are great. But for those I want the whole enchilada. If I'm going there I want everything the EC2 management console and API gives me including full-blown VPC, etc.

This seems to occupy an uncanny valley. Without IPv6, direct networking, etc. it's a crummy VPS, but it's not as rich as EC2. The only pluses I see are direct access to AWS services (but if I want that I probably want EC2) and AWS's security and uptime "guarantees."

Problem with the latter is that it's largely marketing. I've routinely clocked 300-day-plus uptimes on Digital Ocean and I've also had EC2 instances mysterious die or go into a coma. They might have something to say on security, but I've never seen any real proof that AWS security is intrinsically superior to their competition. Neither DO nor Vultr has had a recent major breach AFIAK and they all seem to use the same virtualization tech.

Recipe:[{"op":"From Base64","args":["A-Za-z0-9+/=",false]},{"op":"Drop bytes","args":["0","4",false]},{"op":"XOR","args":[{"option":"Hex","string":"AB"},false,true]}]

Am I missing something? This is a very simple example.

The simple python code that decodes it is this:

def decrypt(string): key = 171 result = "" for i in string: a = key ^ ord(i) key = ord(i) result += chr(a) return result

string = "AAAAKtDygfiL/5r31e+UtsWg1Iv5nPCR6LfEsNGlwOLYo4HyhueT9tTu36Lfog=="

result = decrypt(base64.b64decode(string)[4:])

print "decoded: ", resultprint "Length: " , struct.unpack("I", string[0:4])

From the backing Github readme, which as far as I can see is not directly linked on the page:

> "Cryptographic operations in CyberChef should not be relied upon to provide security in any situation. No guarantee is offered for their correctness."

Now, it's fair to say that professional security types should assume the 'no guarantee' bit. But it's not fair to offer it up as a one-stop-shop for non-programmers to handle encryption tasks, and then offer no caveat at all in the primary reference page.

I clicked over to this, prepared to hate-read it and leave a caustic comment.

(background: I live on a farm, and have come across dozens if not hundreds of websites that promise to "open source", and/or "crowd source" "innovative", "new" plans for farm tools, all of which are either useless, overly complicated, too much work to build, or better bought as a working product from Tractor Supply.)

...and - much to my surprise - this website actually has a fair number of really decent ideas.

"Pastured pig waterer", "Home built no-till seed drill", and a few others all look interesting.

FWIW, over the next year or two I'd like to design and weld up a potato row mounder and a potato harvester, both designed to attach via three point hitch to my tractor. They're commercially available, but not locally, and shipping on big stuff like this is killer.

I recently wrote[0] something related about my observations on toolmakers and their craft.

"In life you're a tool maker or a tool user. What we're building at Baqqer[1] is a tool. Here's something I've noticed about tools and the people that make them. There are ultimately two types of tool makers.

The first type of tool maker is an observer and participant of their own craft, and as such can make very insightful decisions on how to devise a tool from the systematic understanding of what explicitly and implicitly goes into the work being shaped by these tools. Typically these tools are utilitarian and without form in excess beyond what is absolutely necessary to accomplish the task. This is the truest form of tool.

The second type of tool maker is an observer, but not a participant in a craft. These tool makers tend to be cloning tools with small changes, or seeing a problem where there might not be one, because they might not truly understand the way makers participate in this task of their craft. This is the weakest form of tool.

To say there is not evidence to support contraries in both statements is false, but I would expect these instances to be outliers. These statements also do not dismiss the contributions made by outsiders of a craft, as there is something to be said about observing outside the traditions of a craft. I would even suspect large leaps of innovation in the craft might be made from the application of knowledge and modes of thinking leveraged from other/disparate pursuits."

These FPGAs are absolutely _massive_ (in terms of available resources). AWS isn't messing around.

To put things into practical perspective my company sells an FPGA based solution that applies our video enhancement technology in real-time to any video streams up to 1080p60 (our consumer product handles HDMI in and out). It's a world class algorithm with complex calculations, generating 3D information and saliency maps on the fly. I crammed that beast into a Cyclone 4 with 40K LEs.

It's hard to translate the "System Logic Cells" metric that Xilinx uses to measure these FPGAs, but a pessimistic calculation puts it at about 1.1 million LEs. That's over 27 times the logic my real-time video enhancement algorithm uses. With just one of these FPGAs we could run our algorithm on 6 4K60 4:4:4 streams at once. That's insane.

For another estimation, my rough calculations show that each FPGA would be able to do about 7 GH/s mining Bitcoin. Not an impressive figure by today's standards, but back when FPGA mining was a thing the best I ever got out of an FPGA was 500 MH/s per chip (on commercially viable devices).

I'm very curious what Amazon is going to charge for these instances. FPGAs of that size are incredibly expensive (5 figures each). Xilinx no doubt gave them a special deal, in exchange for the opportunity to participate in what could be a very large market. AWS has the potential to push a lot of volume for FPGAs that traditionally had very poor volume. IntelFPGA will no doubt fight exceptionally hard to win business from Azure or Google Cloud.

* Take all these estimates with a grain of salt. Most recent "advancements" in FPGA density are the result of using tricky architectures. FPGAs today are still homogeneous logic, but don't tend to be as fine grained as they were. In other words, they're basically moving from RISC to CISC. So it's always up in the air how well all the logic cells can be utilized for a given algorithm.

Given that the Amazon cloud is such a huge consumer of Intel's X86 processors, even using Amazon-tailored Xeon's, it's surprising that Amazon chose Xilinx over the Intel-owned Altera.

These Xilinx 16nm Virtex FPGA's are beasts, but Altera has some compelling choices as well. Perhaps some of the hardened IP in the Xilinx tipped the scales, such as the H.265 encode/decode, 100G EMAC, PCI-E Gen 4?

For complex designs the simulator that comes with the Vivado tools (Mentor's modelsim) is not going to cut it. I wonder if they are working on deals with Mentor (or competitors Cadence and Synopsys) to license their full-featured simulators.

Even better, maybe Amazon (and others getting into this space like Intel and Microsoft) will put their weight behind an open source VHDL/Verilog simulator. A few exist but they are pretty slow and way behind the curve in language support. Heck, maybe they can drive adoption of one of the up-and-coming HDL's like chisel, or create one even better. A guy can dream...

I do a lot of marketing, and I smiled seeing what you spent money on. I've been most of those places with bigger budgets and similar results. When I'm working with good companies it usually turns into something more like product management with some relevant search or contextual advertising.

> We fell into a trap. We thought marketing meant we had to come at people sideways to get them to give us money. Turns [sic] out, the games just good and people want to play it.

One small suggestion: you're not doing a great job on the up/cross sale. I went to your site and added the game to the cart. But after reading about the expansion I WANTED the expansion. Make it easier for people to add them on. Every large ecommerce store does this. It's helpful to your users, increases RPS, and (when done right) relevant enough to not be annoying. Make sure to find a non-popup solution that won't get blocked by ad blockers.

I'll be buying the product and an expansion based on the Amazon reviews: good luck making some money!

Manufacturing in China vs the U.S.: for my company's Kickstarter project, the U.S. was about 5x more expensive. (It's a bit different for electronics).

However, after flying me and my co-founder to China, living there for a month to work out all the kinks in the process, then the incredible cost of shipping and customs taxes (has to rush ship for Christmas of course), I'm thinking the U.S.would have been a better choice (at the small volumes of 1000 per batch we were doing).

Now, if you are making 50,000 or a million of something, then China is definitely the way to go. But for small batches I recommend shopping around U.S. factories... They're pretty desperate for it at this point.

Not specifically direct to this post but something relevant.

We had that discussion with a colleague yesterday while we are thinking of starting a company ourselfs.

The only thing I actually told him that if we start off something I dont want it to focus on investments or anything crazy and I'd like to go very humble with everything. Create a small business with a product and let it grow in a normal pace.

Atm we are both working for 2 entrepreneurs that started a small company and slowly slowly grew it up to a medium company that returns over 50m a year. Its a very stable environment and they don't go into heavy risks when it comes to spending.

I see a lot of people nowadays that are very proficient in tech doing startups. Startups are everywhere. The main thing we see though is that most of them fail at it. I mainly think its because they are not experienced enough on how life works and they think they gonna make the next uber etc. NO! Thats a big NO! People that created uber are like people that win the lottery. They were lucky enough to get investments they way they did etc and kept at it. Thats all about it. For me its not a success story about a company that started small and ended up big. Its just the lucky draw that investors picked up and threw money at.People around tech industry need to realise that. Start a company, have a product, and go slowly with it. Stick with it and yes in 10-20 years time you'll be at some good amount of money. Don't expect it to happen in a year or even 5 years or else you are stressing your company to fail.

I feel like this is the issue with the tech industry entrepreneurs atm. They want to have it all fast, and thats why they fail.

Also you see people celebrating investments... I love the show "silicon valley" because it shows you in reality what this industry is about. When you get an investment you shouldn't be the happiest person in the world, you gonna get people demanding stuff etc which will definitely put you in a difficult position especially if the company and the product is very young as the investors might wanna take a different path and lead you into taking it as well.

Imagine the setbacks his company had, except then add the delay of cross ocean (air or ship) shipping. Unless things had gone perfectly with the Chinese company, they may still have gotten a faster turn around having it in the US. He mentions in a comment here that they're thinking about doing a second batch overseas, I'm curious to see the turnaround on that.

It also means you're paying extra for manufacturing, transporting, storing and then shipping... empty space.

The size of the box seems huge if the game is just a deck of cards (which it seems to be from the demo video? There doesn't seem to be a board or anything like that?)

Is there a way to instead offer different versions of the game, that are simply different sets of cards, that can be played independently (and therefore do not need to be stored together by the end users).

Also Matt Godbolt's gcc explorer is the the bee's knees for understanding assembly

https://godbolt.org/

I think that playing around with it for 2 hours will teach you more than most classes on the topic. It really drives home why interactivity is such a bit deal in education.

You should also try writing a script for counting instructions in binaries. It's pretty illuminating. Here are some sample statistics https://webcache.googleusercontent.com/search?q=cache:j0gebK...

What a train wreck! Its hard to imagine a more confusing state of affairs.

I'd say that's more attributed to someone many many years ago deciding they would not follow the official Intel syntax (for what reason I do not know), and somehow convincing the rest of the community to follow them. That's actually one of the things that could make for a very interesting article: how one processor family got two different and incompatible Asm syntaxes. The fact that the mnemonics and syntax don't correspond to those found in the manufacturer's datasheets and manuals just increases the barrier to understanding. As far as I know, the same didn't happen to ARM, MIPS, SPARC, and the others. Especially when the sense of the comparisons/conditional jumps is reversed, and some of the more advanced addressing modes look less-than-obvious, it's hard to imagine why anyone would adopt such a syntax:

http://x86asm.net/articles/what-i-dislike-about-gas/

Note that the GNU tools have option to use Intel syntax too, so you can avoid some of the confusion (in the DOS/Windows and embedded world at least until recently, Intel syntax is overwhelmingly the norm.)

To understand assembly it really helps to know at least something about how computers work on a low level. When I first tried learning it (long time ago, in a high school) I had no idea how computers really work on such a low level, how CPU's addressing registers and that kind of stuff, and while I managed to learn the syntax, even write some asm code, it was all really confusing to me. And only few years later on University, after I've learned in details about the cpu architecture, registers, buses, DMA, etc, it suddenly all started to make perfect sense and became 100x more clear and easier. So if you're interested in this, it will save you a lot of effort to invest some time first to learn the computer architecture basics, and then from there go to learn the assembly lang. Just my $0.02

So, this is fantastic, but I want to make an appeal for the most important thing to understand about any assembly language, even before you work out the individual instructions:

Break your programs into basic blocks! Reverse engineers never read assembly in a straight line. Instead, they read the control flow graphs of subroutines, which is the graph where nodes are runs of instructions ending in jumps and branches, and the edges are the jump targets. I hope this doesn't sound complicated, because it isn't: it's literally just what I wrote in this paragraph. It takes about 15 minutes for most platforms to learn enough to recover CFGs from subroutines by hand.

To get a decent understanding of what a chunk of assembly code is doing, all you really need is:

* The code broken into subroutines (this is usually your starting point) and then CFGs (good disassemblers do this for you, but it's easy to do by hand as a first pass)

* The CALLs (CALLs don't end basic blocks!)

* The platform's calling convention (how are arguments passed and return values returned from subroutines)

There are two tricks to reading large amounts of assembly:

1. Most of the code does not matter, and you won't be much better off for painstakingly grokking it.

2. Virtually all the assembly you'll see is produced by compilers, and compilers spit out assembly in patterns. Like the dude in The Matrix, after an hour or so of reading the CFGs of programs from a particular compiler, you'll stop having to read all the instructions and start seeing the "ifs" and "whiles" and variable assignments.

x86 is the worst ISA. If you want to play with assembler without feeling a desire to stab yourself and end it all, I recommend ARM.

Or go learn Z80, x86's weird, 8-bit cousin (it had a 16-bit version, but it sold poorly), which had a greater emphasis on backwards compatability (you can run code from the original 8080 on a Z80, unchanged), and is nicer to work with (because it wasn't extended in unticipated directions far beyond its original capabilities, while keeping fetishistic backwards compatability by stacking hack on top of hack on top hack. It also didn't have memory segmentation, otherwise known as The Worst Thing.)

There are only two common reasons to learn Z80 assembler, though: to program the Gameboy (which runs on a modified Z80 with all the cool instructions removed), and to program a TI calculator, thus making all highschoolers in your area immensely happy.

TI calculators are a comically overpriced scam, that have only survived because of the College Board, but that's another story.

And, of course, modern compilers will usually produce faster, more optimized code than you ever could, without making any mistakes.

This assertion comes up over and over again in the last 30 years. Every time I've had it asserted to me, it always came from non-assembler programmers, who always wrote in a high level language. I have yet to see evidence of optimizing compilers generating code even remotely close in efficiency to what we would code directly in assembler.

A coder would never write all those extra frame pointer setup code, nor would they waste encoding and tact cycles shuffling values from one register to another. For example, a human might write the code from the article thus:

 Add42: addb $42, %al ret
and that's it. No frame pointer or stack setup, that's all unnecessary overhead because compiler algorithms can't reliably make such contextual decisions.

As AT&T syntax is still being used, at this point I'm willing to believe it's to purposely make x86 assembly hard and unpleasant to read and write.Perhaps so people will want to stay away from it, and in a way, to reduce the amount of code that is tied to the x86 platform.It spreads the thinking x86 assembly is terrible and ugly.

Intel syntax is much cleaner, in particular, Intel Ideal (as opposed to MASM), and specifically, FASM (flat assembler).FASM makes it as clean as possible and turns writing assembly into a joy.

Compare:

 movl %fs:-10(%ebp), %eax ; AT&T mov eax, dword ptr fs:[ebp-10] ; MASM mov eax, [fs:ebp-10] ; FASM

I thought this sentence was curious:

"To write code that runs directly on your microprocessor you need to know how memory segmentation works"

Although you can't completely ignore segments, in practice at least on Linux the only segments in use are user code/data and kernel code/data segments.

Does anyone know why the author might suggest that understanding segmentation is necessary to write Assembly code?

Reading assembly language is about having the computer in your head, just like regular programming. You read and execute the instructions just like any other language, just the operations are that much smaller and less abstract. Each instruction is a 'function call'; just like any low level language you leverage abstraction to build up these operations into greater pieces of execution knowledge using macros and functions in logical ways to get the outcome.

It's not magic. The best way to learn assembly is to program in it. I learned on the Gameboy by getting a job and programming 2 games in it. Fun as hell, especially when the machine is small enough to really fit in your head and clock cycles count at 4Mhz.

The examples seem odd to me: the argument order is reversed from every Intel disassembly (or assembler) I've ever used. Addi edi, 43 is the normal way to say "Add 43 to edi". The destination register is normally first; the source register 2nd in the disassembly, right?

A value in the range between -4095 and -1 indicates an error, it is -errno.

The syscall/errno stuff has always seemed unusual, inelegant, and inefficient --- instead of just returning a negative error code directly, the function returns the vague "an error has occurred" -1, and you have to then check errno separately after that. It only adds insult to injury when you realise that the kernel itself isn't doing it, but the syscall wrappers. And thanks to POSIX standardising this mechanism, the alternative will likely never get much adoption; of course, if you write your own syscall wrappers like this article, then you can skip that bloat.

For now this guide is linux-only, but I will be writing a windows version when I feel like firing up a virtual machine.

Unfortunately the Windows syscalls are not officially documented and even less stable than on Linux, changing even between service packs.

At least on Linux the first few (i.e. the oldest, most common and useful) syscalls have not really moved around over the years:

A few thoughts:

* The space savings are moot as other processes such as the daemons are going to load libc into virtual memory anyway, and the kernel shares libc's page among all processes.

* This adds a lot of LOC you have to maintain, instead of shoving it off on the compiler/libc vendor, this increases the chance of bugs.

* This will prevent the use of VDSOs to optimize high volume system calls like gettimeofday.

* It's still probably good to know how these happen, even if you're not doing them yourself.

* The only place this would really see benefit is in a single process environment, however in those cases I would suggest a unikernel anyway for simplicity sake.

If the asm was written a little more cleverly, the syscalls would avoid almost all moves, because the compiler'd put everything in place:

 _syscall5: mov %r9, %r10 _syscall3: mov %rcx, %rax syscall ret
And then:

 extern unsigned long _syscall3( unsigned long, unsigned long, unsigned long, unsigned long); extern unsigned long _syscall5( unsigned long, unsigned long, unsigned long, unsigned long, unsigned long, unsigned long); #define syscall0(NUM) _syscall3(0,0,0,NUM) #define syscall1(NUM,A) _syscall3(A,0,0,NUM) #define syscall2(NUM,A,B) _syscall3(A,B,0,NUM) #define syscall3(NUM,A,B,C) _syscall3(A,B,C,NUM) #define syscall4(NUM,A,B,C,D) _syscall5(A,B,C,NUM,0,D) #define syscall5(NUM,A,B,C,D,E) _syscall5(A,B,C,NUM,E,D)

The comment section where gcc puts in ident info can be omitted with -fno-ident and syscall(2) is usually a very thin wrapper[0]. If you follow the musl syscall(2) it simply maps errors to errno[1] and uses the fancy count-args-in-macro[2] to call off the respective $arch/syscall_arch.h[3] syscall$n numbered functions.

A little self promotion but mostly because it addresses some of the other commenters concerns about malloc (or the lower-level api around sbrk): a couple years ago I wrote rt0 [0], a small (mostly minimal) C runtime for i386 & amd64 that makes it easier to replace libc & crt0 (as long as you have the kernel headers installed). Also, as part of the examples, I wrote wrappers around the sbrk syscall. Pretty easy to do and all documented in the repo. I expect to eventually port the lib to arm (raspberry pi) and aarm64. There's also lots of references to other small c runtimes. I'll be adding this one as well.

I think this is unnecessary when you got <stdint.h>:

 typedef unsigned long int u64; typedef unsigned int u32; ...
if you define your own types like this you may need to revise them when you switch architecture or even compiler.

Now you could argue that this is part of the standard library, but I actually see it as a part of the standard C language.

Assembly implementations of any trigonometric functions used

While there is code that goes to that effort (The Go runtime comes to mind), it's quite a pain for "normal" code.

Have to say the evolution in LEDs has been pretty amazing.

First we had terrible yellow fragile maglites that requires several large C or D cells for anything approaching reasonable brightness and battery life. I had my small maglite die at the bottom of the grand canyon, and the top of MT shasta. After trying to replace a tiny incandescent bulb in the dark in challenging conditions I decided I was switching to LEDs, no matter what the compromise was.

Similar monitors had broad spectrum CFLs that generated UV, converted it to white light with a phosphor then threw away most of the light and filtered it down to approximately R, G, and B. The resulting color accuracy was terrible.

LEDs started out expensive, not very bright, and mostly red. Migrated to different colors, I think blue was the most expensive.

Finally white LEDs started showing up in tiny AA or AAA flashlights with 50-75 lumens. About as bright as the 2xAA maglite that were huge in comparison.

Color coverage got better, life got better, efficiency started ramping up.

100-200 lumen flashlights started to become more common. 18650s that have substantially more power and a more LED friendly 3.7V started to appear.

Year or two later 400-500 lumens were common, efficiency kept increasing. Started to appear as backlights, car dash boards, brake lights, etc.

CFLs switched from wasting 95% of the light to ditching the white phosphors for a mix of RGB phosphors. The savings were twofold and multiplicative. The first was generating UV -> RGB directly with mix of RGB phosphors in the CFL. Then additionally instead of narrow notch filters that didn't pass much light they switched to very wide spectrum filters that passed most of the light. So a red pixel didn't need to be within 1% of red, but instead just block 99% of G and B. Since the RGB phosphors emitted very close to the ideal frequencies the color accuracy increased. Monitor power requirements dropped significantly.... only to be killed off by more efficient LEDs.

Things doubled again, small ish flashlights much like the 2xAA maglites except fatter. 1000 lumens hitting $50-$100 points points. Now throwing a usable light 300 Meters isn't unusual from a small hand held light. Depending on your use recharging once a month isn't unusual. 4-or 5 light levels are common, and runtimes of 1.5 hours (max light) to 100 or more hours (on low) aren't uncommon.

So now macbook pros that are extremely thin (greatly helped by very tiny LEDs for backlights) get 10 hours of battery light with 500 nit screens with wonderful color accuracy. Similarly even 55" LED screens are crazy high resolution and crazy cheap. The cost per pixel doesn't seem on that crazy different than the cost per transistor.

Sadly like Moore's law, LEDs aren't getting much better anymore. For the first time I purchased a new flashlight after 2-3 years... and the best I could find was zero % brighter 8-(.

It's not just computers that have been improving like crazy.

It would be more credible if the Cabot Institute linked the paper on their "All Research Papers" page (http://research-information.bristol.ac.uk/en/organisations/c...) or if they described how they are getting electricity out of beta decay (is it simple a thermo-electric generator? How much heat differential can they push? Or is it just bodging together chunks of radioactive material in a casement that has reasonable head conductivity and absorbs 99% of radiation.

My favorite "invention" of that form is the water heater "booster" ball.

I can see that they are emphasizing on the #DiamondBattery hashtag so that general public will be hooked and share it more, but why haven't they given any hints (mildly technical) to the capabilities of the battery?

// A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current.//

When I read the "small electrical current", the physicist in me was naturally assuming a very small current of the order of pico to nano amperes (without being conservative) - essentially useless. Metrics like the half life of the battery doesn't make any sense at all if the power or current rating is not specified. Current rating is something you could trust, that it will end up as a viable product.

This would appeal more if they can give a direct link to their research paper.

This particular thing 'feels' sort of slimy (to me at least, but I suspect to others on this site as well), but I think that's a bad reflex on my part, and that easy, low-friction things like giving people an opening to send a quick tweet or FB post reaches a different audience than having a stand at the 'open science fair' or having a lecture open to the general public; those tend to self-select in the audience they attract, to put it mildly.

With such nonsense it is hard to believe the rest of the article. Heat a diamond and it will burn releasing CO2 into the air, smash it with a hammer and it will burst in million parts.Small particles and gasses are very easy to ingest.

This is no diamond-age. These devices are all well and good, but think of the scales involved. To generate enough power to do something like power a home, let alone a vehicle, we are going to need kilos of this stuff. Kilos of diamond. It's also going to get rather hot. That is the point.

Using numbers from patch_collector:1 x 50watt lightbulb / 0.0013 Watts/gram = 38Kg = 83lbs of diamond per bulb.

Diamonds are far from indestructible. They shatter. More importantly, they burn. We don't see it very often but put enough of them together, add heat and electricity, and you better hope there isn't any oxygen nearby. Imagine a couple pounds of these things, on fire, pumping out radioactive carbon dioxide. At least when uranium burns it produces something heavy that can be filtered. Filtering radioactive CO2 would be a nightmare. These things will never find there way into any consumer product.

Given that Bristol researchers did not explain the physics behind their diamond battery we can only speculate but considering some recent developments we can make some good guesses.

It probably functions similar to a betavolatic cell.(See: https://en.wikipedia.org/wiki/Betavoltaic_device)

In a typical configuration you have a P-N semiconductor junction placed next to beta emitter. The beta particles impact the PN junction and create electron-hole pairs that are pulled apart by the junction to produce a current.

The use of diamond seems like a could be a significant innovation:1) Carbon-14 is an efficient beta emitter and could make op part of all of the diamond material.2) Diamond has a wide band-gap which is necessary for high efficiency conversion to electricity.3) Has strong resistance to radiation damage.

In one configuration the diamond would be layered on top of a silicon P-N junction so it works like a conventional betavoltaic device.(see: http://large.stanford.edu/courses/2013/ph241/harrison2/)

A recent patent shows that diamond is a very efficient moderator for injecting electrons into the junction.(see https://www.google.com/patents/US9064610)

Considering that diamond is itself a semiconductor we could also do away with the silicon. For example diamond is being considered for highly efficient photovoltaic cells.(see: http://exploration.vanderbilt.edu/news/news_diamond.htm)

It is also being considered for production of next-gen schottky diodes.(see: http://www10.edacafe.com/nbc/articles/view_article.php?artic...)

The diamond could be stacked next to a conducting metal to create a Skottky barrier which is a type of P-N junction. The beta particles would excite the electrons with enough energy to push them over the barrier and create a current.(see: https://en.wikipedia.org/wiki/Schottky_barrier)

Normally with nuclear power you use the heat generated to drive a heat engine of some sort with strict limits on the theoretical efficiency. But many pulse fusion designs look at using the momentum of emitted charged particles directly through their interaction with magnetic fields at far higher efficiency than could be achieved with the energy going through a heat stage. Carbon-14 emits only beta particles which are, of course, all negatively charged. I wonder if they've managed to turn those into a very high voltage, very low current continuous source directly?

(Note this math is a thought experiment ... completely off the cuff and utter non-sense.)

Based on their numbers:

AA is about 700J/g @ 20g gives about 14000J and a 24 hour drain gives us 580J/hour.

DiamondBattery is about 15J/day or ~0.5J/hour

Ignoring voltage issues (among other things), we come to 1.1kg of DiamondBattery being able to supply something that would drain their 20g AA in 24 hours.

The math here is complete off the cuff non-sense, but an extra kg or so here is not unreasonable for some fixed applications ...

would a standard diamond also do that trick, I don't see why a radioactive diamond would be different if it is in the presence of C14?

brandmeyer 1 day ago 0 replies      
10:1 odds that this is just a use of the photoelectric effect with a clever dielectric. Based on the press-release description, it is probably not a radiothermal generator (like that used in deep space probes).

1) Have an ionizing radiation source.

2) Get a robust dielectric, with metal plates on both sides of it. Call the plate near the radiation source the cathode and the far one the anode.

3) As the ionizing radiation impacts one side of the cell, the released electron travels only a short distance through the cell. Ideally, the first interaction is with a cathode and the far side an anode, imparting a negative potential to it.

4) A potential difference now exists between the far-side anode and the near-side cathode, from which you can draw current.

Strictly speaking, this is a more like a capacitor which is trickle-charged by the radiation field rather than a battery. There is a design tradeoff between thickness of the metal and dielectric layers in that the initial and final ionizing interaction must be of a (cathode/dielectric -> anode) or (cathode -> dielectric/anode) to get any energy out of it. Ideally, the dielectric has an extremely small cross-section for interaction with whatever the ionizing radiation source is, while the metal plates interact very strongly. However, there will always be some losses due to internal ionization of the dielectric itself. I'm not sure how you would build an effective multi-layer structure, either.

Is this preferable to an RTG? Almost certainly not. The vast majority of the radiation energy in an ionizing photoelectric-effect cell is still released as heat. Very little energy can be captured this way, so it is quite inefficient in terms of energy produced relative to the radiation emitted. You can extract some more electric work by pre-charging the cell such that the freed electron is slowed in part by the electric field gradient, but in practice the bulk of the energy is still lost as heat.

Sea story time! The internal electric field within the dielectric will produce some weird mechanical stresses, too. When my ship's reactor plant went through a refueling overhaul one of the things they replaced was the reactor compartment windows. There are a couple of leaded glass windows that allow Mk. 1 eyeball inspection of the reactor compartment during operation. They are quite thick, electrically insulating, and they build up a large internal electric field along with internal stresses. Standard maintenance was to replace them well before the stress could fracture the glass.

So... could the press release be ...excessively breathless? My guess is a qualified "probably". The physics behind the photoelectric effect are well known and understood. Diamond is special in part because it has a fantastically high dielectric breakdown strength. So, you can extract more work out of the ionized electrons by supporting a very high potential gradient between the anode and cathode, which could be seen as a breakthrough for this type of energy conversion device. BUT it also would enable a new generation of high-density ultra-capacitors. The energy density in a capacitor is limited (in part) by the breakdown strength of the dielectric, since the stored energy is a volume integral of the squared electric field strength. Since ultracaps are technologically much easier to commercialize, and much more investor-friendly than anything involving an ionizing radiation source, but that isn't what the press release points to, I think it is likely to be ... exaggerated.

I could also be wrong, and we'll soon have a new generation of ultracaps!

Love it. I think the most discussion-worthy quote I found in the docs is this:

> It's currently fashionable to avoid two-way binding on the grounds that it creates all sorts of hard-to-debug problems and slows your application down, and that a one-way top-down data flow is 'easier to reason about'. This is in fact high grade nonsense. It's true that two-way binding done badly has all sorts of issues, and that very large apps benefit from the discipline of a not permitting deeply nested components to muck about with state that might affect distant parts of the app. But when used correctly, two-way binding simplifies things greatly.

I wonder what the author considers "used correctly" and "done badly" and how Svelte approaches this.

TodoMVC is a useless benchmark for the problem that this claims to be addressing. The limits we're hitting with our applications now are with BIG applications, with many routes, many views, and lots of client side logic. We're talking hundreds of files (in some cases, thousands). Of course a framework, with it's fixed overhead, is going have a bigger payload for a tiny demo app like TodoMVC, than something like this which compiles to some amount of overhead which grows seemingly linearly with application size.

That said, I'm not criticizing the framework here, and I welcome new ideas, but a better choice of benchmark is sorely needed to be persuasive here.

The precompilation is a nice idea, but I'm not buying the "vanilla JS" argument. The reason why React and other frameworks have a runtime is also because they optimize rendering.

The Svelte doc says: every call to `component.set()` produces a synchronous DOM update. I can already see how this leads to very poor rendering performance in applications with a large number of nested components.

React and the Virtual DOM solved this problem, and that's why web apps today use a lot of components. So until Svelte can demonstrate fitness and speed comparable to React on large apps, it just looks like Yet Another JS Framework.

I'd personally go with Polymer if you like scoped CSS, since it's already established and it's a good project.

I wonder if these ideas can be somehow applied to React, doing precompiling on React components, so that one can continue taking advantage of all freely available React components out there, and keep using Redux.

A side note about that website. Thin and Extra-Thin fonts have no place in web design (there are some exceptions in huge title text). They are an unnecessary burden for people with limited eyesight and elderly people[1]. Even for me, on my 1366x768 screen (which is still the single most common resolution for cheap notebooks, dear HiDPI web designers[2]), the bullet text is hardly readable, the copyright line is completely unreadable. This effect is made even worse by choosing inadequate contrasts[3]. One can use subtle colors for increased contrast.[4]

I wish I could like this book, but after reviewing the first chapter I can only imagine the confusion of students. I support very much the idea of breaking the book into levels, but it attempts to cover far too much, far too quickly and I don't believe this book would be useful for those who are not already familiar with the language.

I've been writing C since the late 1980s, moved to mostly C++ by the mid 90s, C# in the 2000s, and now I've come back to C. Most recently built some realtime components and drivers, having to drop back to C77. I mention this as I've taught many colleagues along the way and I'm sensitive to the places where beginners tend to get hung up with problems and I've come to anticipate many of the questions along the way. Let me take a moment to illustrate the base of the problems i see:

"Too much, too fast." The best example is right on page 2: a program which demonstrates a complex printf format string, along with arrays and loops. I can't help but sarcastically ask "Are you sure that is how you want to introduce someone to the language?" A beginner's eyes will glaze over.

Seriously, the way to introduce the language is simple examples. Explain the main is the entry point where all programs begin running, and that main returns it's success or failure to the operating system (or other program that called it). 3 lines of code.

Then add a SIMPLE print, if you wish, or a variable declaration. Int. Float. char. again, it MUST be simple.Introduce loops.Then show how to move some functionality out of main into a subroutine/a new method/new function, how to call that function, and return results. Talk about header files, etc.

From there, dive into the rest of the base language... talk up arrays, memory management, heap/stack, pointers, libraries, exceptions, etc.

But this is only my experience, and I'm sure that it is different for others. Kind regards.

While I like a lot of what's in here,

 for (size_t i = 9; i <= 9; --i)
is a pretty terrible example to put in the second chapter. I would not let that line pass code review. There is no need or place for cutesy cleverness in C.

EDIT: Ugh, just found this too:

 isset[!!largeA[i]] += 1;
Not only is that confusingly cutesy, but largeA[i] is a double. Please DON'T write or encourage beginners to write! such smug code!

EDIT2: In section 5 is the statement than unsigned integers "can be optimized best." This is flatly untrue on x86 and I suspect many other architectures. Compilers can and do take advantage of undefined signed overflow to optimize signed arithmetic; the same is not possible with unsigned arithmetic. See https://kristerw.blogspot.com/2016/02/how-undefined-signed-o...

I'm really surprised by the "hate" for C that is appearing in these comments. What ever happened to actually enjoying the danger of getting low level? Is assembly also useless because it isn't readable?

There is a lot of great code written in C, and a lot of crappy code written in C. Because C doesn't protect you from yourself, it exacerbates any design flaws your code may have, and makes logical errors ever more insidious. So in this sense, the quality of the C you write is really a reflection of you as a C programmer, not the shortcomings of the language. Maybe you've been badly burned by C in the past, but keep an open mind and understand that C can be beautiful.

It's been a decade or more since I've worked in C (and have never been a heavy C coder). Is "modern C" really a thing?

I mean, is there some subset of C that is safer than what I think of when I think of C? I know about stuff like reference counting techniques, rather than manual memory management, for example, and that goes miles towards safer coding. But, even so, the variety of ways you can shoot yourself in the foot with C are seemingly beyond counting. Are threads and async easier and/or safer now than 10-20 years ago, and with more direct language or standard library support? Is memory management in the standard library safer today? Are there concurrency primitives (beyond low-level interacting with epoll or kqueues or even fork or whatever)?

I mean, it's obviously possible to write reliable, safe, secure, software in C (Linux, Git, SQLite, all come to mind), but how much easier has it gotten? Would anyone choose C for a new systems project with no legacy baggage or dependencies, in a world with Rust and Go?

It's nice to see this perspective kept alive. I put some effort into a numerical library (github.com/maedoc/sddekit) in C99, and I didn't find the language lacking until I tried to imitate inherited interfaces with virtual dispatch by hand (empirically I can say, a poor move in C lib design).

I did find it useful to apply rules like only use uint32_t, double & bool as primitives.

My main wish is that it would be possible to opt into automatic const & restrict, as a compiler flag or pragma, so that something like

https://github.com/maedoc/sddekit/blob/master/doc/C.md#alias...

would be easier to do.

Goto is considered useful by the book:

The use of goto and similar jumps in programming languages has been subject to intensive debate, starting from an article by Dijkstra [1968]. Still today you will find people that seriously object code as it is given here, but let us try to be pragmatic aboutthat: code with or without goto can be ugly and hard to follow.

Having worked at both places for ~4 years each, I would say Amazon is much more of a product company, and a platform is really a collection of compelling products.

Amazon really puts customers first. Their platform and organization are made up of small teams that own services with well-defined interfaces, accountable for customer metrics. All profits are reinvested, so resources and perks are scarce, efficiency matters, and management is tight. The platform emerged because internal teams thought of their infrastructure services as products with customers.

Google really puts ideas (or technology) first; it aims to hire the smartest people and rewards them for launching new things and solving complex problems rather than optimizing UX or making customers happy. Resources are ample and management is loose, so individual contributors can try new things with greater leisure. It's been compared to grad school. But simplifying customer experience is less of a priority, so the internal infrastructure was notoriously complex and hard to use. They're now learning to prioritize customers, but it's hard to change culture.

Of course, both companies are huge and diverse and evolving, so you'll find plenty of variance.

App Engine wasn't evidence of Google being a product company, nor does it exemplify the company's strategy. It was a grassroots project that for years didn't receive much leadership support, but was still allowed to launch and grow.

If Google released an IDE with tight integration to Google Cloud like Azure + Visual Studio, that's a potential killer app that lowers the perceived switching cost.

If you told me to use Azure two years ago I would've laughed you out of the room. But here I am in 2016, using Azure, using ASP.net + IIS on Visual Studio. that's some powerful shit and currently AWS has cost leadership and perceived switching cost as their edge.

By introducing a layer of learning curve, you lock in your customers but eventually the other guys will race to lower that curve.

I think Ben (who I generally think is right on) in this post misapprehends the effectiveness of generalized data for machine learning services and thus the effectiveness of this approach in Googles strategy here. Perhaps the slide makers in Mountain View have the same misapprehension.

1 - Prediction API - you provide your own data there, so no data advantage from Google there.

2 - Cloud Natural Language API - the effectiveness really depends on what type of text you want to understand. If Googles training data includes information about my type of text application great, but if it doesnt then what? How do I know that?

3 - Cloud Vision API - likewise. Can I subset the training set? Provide my own examples? If they subset, can I inspect the examples?

4 - Translation API seems like the exception here, mainly because the odds are that customers of translation service are unlikely to have collected language pairs and this collection is more highly specialized. But its unclear that this one API would be the deciding factor for many companies choosing which cloud vendor to use.

ML services as a differentiator have yet to be proven out. I am highly suspect. Yes, some big general data sets will be better on some applications than others, but an enterprises own data about their problem will always be better than a huge, general data set. And if youre using your own data anyway, youre going to care about all the platformy things Amazon has already been winning with.

Barring proprietary breakthroughs in unsupervised learning, I dont believe that this strategy as outlined will work in practice.

There's always the simpler explanation to why Google is getting traction:

- Price/performance is better in some/many cases for VMs

- It's easy(ier?) to use

- Clear technical advantage with some of their other services e.g. Load balancers

- Customers prefer when there are multiple companies competing for their business

I get that there are long-term strategies that involve the likes of container services. But just the fact that they are better in some areas will help them get traction. Plus they have a fantastic brand name.

> Amazons AWS strategy sprang from the same approach that made the company successful in the first place

I'd argue that Amazon isn't a successful company, they are a popular company with a few large successes surrounded by decaying and decrepit failures that won't die. But then again I'm biased.

As far as Amazon's AWS strategy, I can't comment (I worked in the retail business side). But I can comment on a relatively small aspect of management that I witnessed. At one point in time I had a very strong need for PostGIS, and I lamented on an internal email list about AWS not having a Postgres version of RDS. I received an email directly from Raju Gulabani, VP of databases in AWS. He scheduled an appointment with me, him, and two product managers. He asked me pointed questions about why I wanted Postgres over the other options, how I would be using it, what extensions I wanted, and what features were important to me. He thanked me for my time, and less than a year later it was released to the public.

In the retail business side, I never had more than 2 minutes at a time with someone at the director level, and not once had I spoken to someone at the VP level. Literally zero communication from the bottom up, everything was top down. Whether AWS had already been working on it or not I don't know, but they definitely took the time to hear my case, and when it was released it was almost perfectly as I had asked for. And that, IMO is waaaay more important than anything regarding the size of a team or whatever the fluff pieces have attributed.

I disagree with the central thesis of this article that Google is a product company rather than a platform company. I think that's wrong because throughout its history Google has asked itself "what if we had this?" first, and built the products around that later. Essentially the company believes that products will naturally emerge if you hire tens of thousands of engineers and deploy an unholy number of computers. I said this before on this site: Google's core product is dirt-cheap computing. Everything else follows from that.

The expedited process takes three years. No wonder the only way that most drugs get approved is because the drug is patented and the company that brings them to market can expect huge profits.

The actual components seem interesting. The odd part of this seems to be the building/requiring process. It seems that there are some implicit dependencies on webpack, which are not well spelled out.

It appears the team chose to make an oddly generically named babel plugin: `babel-plugin-import` which seems to do some manipulation of CSS/SASS/etc styles (which seems out of scope for babel). I assume the generic name was chosen hoping other libraries would embrace a similar pattern, however, I'm not seeing any spec defining how another library should implement this.

These components look and work great, but unfortunately are a real headache to retheme unless you want to pull in a sass/less toolchain in addition to what you're currently using. This is a pain in the ass if you already have your theme variables set up in one compiles-to-CSS language.

There is a standard for CSS variables and a very functional subset of their functionality can be compiled for older browsers at build time: http://cssnext.io, yet as far as I can tell, all of these component frameworks impose some other nonstandard compiles-to-CSS language or one of many possible APIs for writing inline styles.

Inline styles seem to be a trend at the moment but I can only assume the people driving this movement haven't had the experience of working with 3rd party components (which you may or may not have the source for) and needing to alter something the designers didn't expose and simply having no simple options because the damn inline style can't be overridden even by !important. Now you've got to fork whole the f'ing component, possibly multiple, each of which potentially coming with yet another different compiles-to-CSS toolchain all because you wanted to add a single line of CSS.

Admittedly, antd doesn't use inline styles si the above doesn't apply here, but having to maintain a custom builder for antd in order to change some fonts and a few colors was a frustrating experience. Not sure what a good solution is until CSS variables get more browser adoption, but it'd be great if we could collectively start standardizing on standards.

I want to speak generally about new UI components, since this is the 2nd post in a week (about a new library of UI components) that reached front page (that I've seen) which are not addressing what I see as a fundamental issue that future UI libraries should address.

For mobile platforms specifically. Now on the surface you can say that UI libraries these days, more or less, will work similarly if not exactly the same across platforms. I would say for most "types" of components this will be true. But form input field behavior is different enough between mobile platforms that I'm questioning why we aren't moving quickly away from native HTML form input fields.

I totally get the argument for accessibility (probably a lot of accessibility platforms depend on these fields), but even accessibility standards such as ARIA, because of some of these inconsistencies, should be pushing toward this goal (decoupling the form input UI components from native HTML form input fields) I think.

Does anyone else here have a strong opinion one way or another as far as their experience building PWA's on mobile where they've encountered the differences between platforms (I'm specifically familiar with Android vs. iOS)? Do you find the differences to be easy to work around? I'm especially interested in feedback from folks who have required some relatively detailed behaviors, such as consistency in how input fields behave when "tabbing" to the next / previous field, or how the "input type='time'" fields behave differently in terms of when DOM events fire while setting time. Or how native keyboard behaviors / layouts are sufficiently different that you'd prefer to have a way to make the experience within your app more consistent?

By all means, this is not unique to Amazon - not that it makes it any better.

I did a post-grad interview for Epic (epic.com - healthcare software) in a similar fashion, that was at least as draconian.

After passing a 15 minute phone screen, they sent me a link to a service that:

* Installed their proprietary software on my Mac

* Connected me to a real person who verified my DL against who they were expecting

* Had me swing my laptop 360 degrees around the room I was taking the test in, to make sure there were no notes or people assisting me on the quiz

* Took remote control of my computer and force quit any programs in Activity Monitor that were on their 'blacklist' (including Dropbox, etc)

* Gave me what I imagine amounted to a three-hour SAT style test with English proficiency, math, logic, etc.

* The whole time, had that same person watching me through my webcam and watching my screen, to make sure that I was not cheating.

I passed, and during my in-person full-day interview in Wisconsin, they had me do a few more of these tests (that were slightly harder and more about communication skills), as well as some interviews with people in person.

It was an interesting experience for sure - definitely a different side of the coin compared to what a lot of HN is probably used to. I ended up getting an offer that was very good considering they are based outside of Madison, but ultimately decided to go somewhere else.

As a developer at Amazon who does interviews, what the fuck?

I imagine part of this is a response to the very, very large amount of time we spend interviewing interns every winter (I know I typically do 2 or 3 sessions of 3 1-hour interviews in a row). There's just too many interviews to do.

Someone wants to innovate and find ways to sort the good from the bad without SDE time spent, I would guess. I hope this isn't the new system for everyone. Then again, if it saves me hours and hours of phone screens...

Wait, I see nothing wrong with any of this. Obviously Amazon is trying to curb cheating on remote coding/compatibility tests. They don't actually care to collect any info about you beyond what you do during the test. They don't care which websites you visit before or after the test. Or how you use your clipboard - after the test. But during the test, it's not so unreasonable. People do cheat, especially if they can get away with it and when the payoff is potentially huge.

A firm similar to Proctorio, HireSuccess, says this on their website:

I wonder how Proctorio + Amazon reconcile that viewpoint.

Furthermore, if you read the EEOC, some of Proctorio's questions seem to really push the rule: If an employer requires job applicants to take a test, the test must be necessary and related to the job. How is 27:24::64:X related to the job, again?

I find this funny, stupid and creepy at the same time.

Creepy - recording a dude's facial reactions, eye movements, mouth movements.. All this for a remote interview screening?

Stupid - I believe quickly Googling for some documentation, or even better solutions can save loads of a developer time in this day and age with StackOverflow. I would instead consider a person that was smart enough to cheat in a code test like this as a great choice. This reminds me so much of schooling system in India where the kid who memorizes essays verbatim scores higher than the kid who actually understood it and reproduced in own words.

Funny - Did they really think no one would object to this and post this on social media or HN?

My current manager who hired me right out of Grad school tells me, "Interview is a two-way process. A candidate need to be tested whether is talented and is a good fit for the team. Equally importantly, the candidate should be sold on the idea of working for us(company)."

On that case, Amazon has even tougher job of convincing a candidate. Not all sane people would want to work for above average pay while putting up with ridiculous work pressure [thinking about that guy who jumped off of Amazon work place].

I went through Amazon's two online tests in October 2016 while interviewing for a full-time position.

I took the first test just like the OP, the logical reasoning part seemed kind of irrelevant and a waste of time for me. That was nothing compared to the second online test.

The environment of the second test was like a scenario out of Black Mirror. Not only did they want to have the webcam and microphone on the entire time, I also had to install their custom software so the proctors could monitor my screen and control my computer. They opened up the macOS system preferences so they could disable all shortcuts to take screenshots, and they also manually closed all the background services I had running (even f.lux!).

Then they asked me to pick up my laptop and show them around my room with the webcam. They specifically asked to see the contents of my desk and the walls and ceiling of my room. I had some pencil and paper on my desk to use as scratch paper for the obvious reasons and they told me that wasn't allowed. Obviously that made me a little upset because I use it to sketch out examples and concepts. They also saw my phone on the desk and asked me to put it out of arm's reach.

After that they told me I couldn't leave the room until the 5 minute bathroom break allowed half-way through the test. I had forgotten to tell my roommate I was taking this test and he was making a bit of a ruckus playing L4D2 online (obviously a bit distracting). I asked the proctor if I could briefly leave the room to ask him to quiet down. They said I couldn't leave until the bathroom break so there was nothing I could do. Later on, I was busy thinking about a problem and had adjusted how I was sitting in my chair and moved my face slightly out of the camera's view. The proctor messaged me again telling me to move so they could see my entire face.

The whole experience was degrading. If you're wondering why I did it, well, I've been using various AWS services for five years and I admired the work that the AWS team had done. Furthermore, I need the income to support my parents and Amazon was the best chance I had at the time. I got invited to do an on-site interview but I declined once I had another offer, and I'm glad I did.

EDIT: Small detail I forgot to mention. When I was showing them my desk, I had the monitor for my desktop (I was using my laptop for the test) and they asked me to turn the monitor so it was facing backwards.

Reiterating the questions posed at the end,

To what extent should personal ethics play in deciding where a (software) engineer should work? What if the engineer has no other choices for a job, and needs to (make rent/pay the bills/eat food)?

It is true that it'd be pretty easy to circumvent the tracking, by placing paper over the webcam, running the browser in a virtual machine, spoofing data to the browser, and so on. However these are infeasible for most non-technical people, so I don't think it's a real solution. Freedom shouldn't be only for those with extremely technical knowledge.

Look, sometimes you can compromise for practicality. But even then there's pretty much always more than one option. Almost anyone can get a low wage job at department store/grocery store/restaurant/whatever so they can eat, guilt-free, and there are still degrees. You don't have to immediately go for the extreme of selling your soul to the devil, you have other options. (To bring it back to the concrete, especially as a tech intern; there are tons of companies that aren't Amazon.)

I don't really care much about amazon because I hear they monopolize your life and have an aggressive culture. However, I do like me some puzzles:

1. The passage is about the good and bad of fanfiction which is posted on the internet. I pedantically disagree with the exact reading of response 2, but it's the correct one, I believe.

2. Only conclusion 1 is necessarily true, because of the transitive property of inequalities; X ? Y and Z/Y can be rewritten as X < Y <= Z. However, we cannot relate any magnitude information to V and it is not necessarily true that a number becomes larger when multiplied by another number (if we assume X is zero and V is positive, for instance).

3. These kinds of spot-the-pattern questions are incredibly arbitrary. However, the most obvious thing to associate with the alphabet is a numerical association with the letters based on it's placement in the common (but not universal) ordering of the Latin alphabet. When you do that, you see that UVS is the only sequence of letters that aren't "descending" even though letters can't truly be ordered.

4. The No Free Lunch Theorem says that no statistical method can find a pattern on the set of all possible inputs, which is why these questions are all bullshit, mathematically speaking. The only thing that makes 4 a better next step for the sequence 1, 2, 3, is that our own personal experience tells us that counting is fairly common, but enumerating the squarefree numbers isn't. You could also make the case that 27:24 has the pattern of 3^3:3^3-3, so maybe 64:x is 4^3:4^3-4 making it 60, but this doesn't feel in any way obvious to me, so I have no idea what they're thinking.

> What if the engineer has no other choices for a job, and needs to (make rent/pay the bills/eat food)?

You're describing a clash of personal ethics and social ethics. Social ethics are saying this kind of tracking is alright, your personal ethics no. So, how strongly do you believe in your conviction? Would it be worth going hungry to stand up for what you believe?

Sort of a sliding scale, huh? The more you are pushed towards survival, the less options you have to exercise your personal ethics. On the other hand, maybe this point isn't as important as it seemed at first thought and you'll decide you're willing to be subjected to monitoring for the duration of the test (but not before or after of course)

* You sing praises to the great leader: the 14 leadership principles.

* Officially they have a zero-tolerance policy for harshness. But I bet if anyone complains to HR they get sent to Siberia (i.e. put on performance improvement plan) or shot (terminated). https://sites.google.com/site/thefaceofamazon/home/fired-for...

* The top management is the Central Committee. They wield massive power. Officially it is a meritocracy but it is all about gaining favors with the ruling party.

* In the warehouses I hear they do these group exercises: Stalin loved public performances

* They like to monitor your microphone, eye, head, and mouth movements : NKVD (the secret police is watching you)

This is called "interview by proxy" and the person generally takes first month's salary as remuneration in cash.

I recently accepted a position at Amazon (have not started working there yet) and I have a similar experience.

The first part of the interview was exactly like the linked experience. No coding questions just reasoning. The second part I had to use ProctorU instead of Proctorio. Personally I thought the experience was super weird but understandable, I'll get to that later, somebody watched me through my webcam the entire time with my microphone on. They needed to check my ID before the test. They needed me to show them the entire room I was in (which was my bedroom). My desktop computer was on behind my laptop so I turned off my computer (I don't remember if I offered to or if they asked me to) but they also asked me to cover my monitors up with something which I thought was silly after I turned them off so I covered them with a towel. They then used LogMeIn to remote into my machine so they could check running programs. I quit all my personal chat programs and pretty much only had the Chrome window running.

The proctored section involved a work simulation and coding questions. Before the coding section started they opened up the Java 7 and 8 docs, C++ docs, and an online calculator in my browser so I could use those for reference. I could take a break in between the two parts but I didn't need to. In total it took about 3 hours for me to finish everything but they said to block out 4 hours. After that I got an offer.

I didn't talk a real person who actually worked at Amazon (by email or through webcam) until I received an offer.

I can understand why people would be bothered or disturbed by these practices but I just thought that Amazon has a ton of applicants and it would take more time for engineers to talk to applicants. In total it took about a month from when I first applied to when I got an offer. I was then flown out to visit Amazon (not for more interviews because I already had an offer) and I actually got a chance to talk to people and learn about teams and ask questions. Yes, I asked multiple different people about Amazon's problems and they all said that their personal experience has been fine but a few said that they know of people who have had bad experiences. Seems like it's dependent on your manager. I know somebody who works there now (not in engineering but works in Seattle) and they love it. I found a team I liked, I talked to people who worked on the team and they all greatly enjoyed it so I accepted after my visit. Everyone who I talked to seemed very passionate about what they do and all take ownership over their projects.

I also applied to other large companies at the same time as Amazon (Google, Microsoft, Facebook, Twitter). Microsoft and Facebook haven't sent me anything. There was a mixup with Google's emails so that delayed my interview process but by the time I started talking to them I had already pretty much made my mind up about Amazon. I didn't go through any real interview rounds with Google, just preliminary screening questions. Twitter sent me a coding challenge but their email also said that they wouldn't get back to people until mid December.

Anyone who has seen Adam Curtis' documentary, "The Trap," will find this familiar.

Our society has become so obsessed with quantification that we have become blind to any other ways of understanding the world around us, and made us poorer in our analysis, instead of being more informed with more information.

It is like saying that if something cannot be measured, then it does not exist.

Had this idea a while back: I really enjoyed auto complete in my IDE and configurable expansions and I wanted that everywhere. I threw together an app to run in the background to keep track of the last word I typed and manage suggestions when I hit a hotkey. Read from a local dictionary, used basic usage frequency and levenshtein distance to recommend, pretty straightforward hacked together in an afternoon project. I could see Anycomplete using a more local suggestion list instead of relying on Google.

Ideally it showed a drop down under where you're typing much like most IDEs would, but support was shotty at best.I really wish there were more OS level hooks for this sort of thing, or a more standardized way to understand what the user is typing and where, but that's not something I ever expect to happen. My app was basically a keylogger while the one in the post is more like a separate entity altogether.

Internet archive is a great project. It has been allowed to be created, in the first place. Then it was and is allowed to exist. This is what I like to about the modern, freer, liberal western democratic nations.

Then there are the great people who spend their time, energy and resources to make such things tick. A great thank you to all those philanthropic people behind the Internet archive and similar such projects. It's because of you, people like me have a hope to learn something significant and with a relatively low cost footprint.

I learned many things thanks to FSF, GNU, Gutenberg, Wikipedia, Internet archive and currently the scihub. I spent only about $10 per month for internet access. Could I even imagine getting such highclass knowledge at such a low cost? Not spent ridiculously high fees for college and still could learn a lot in history, economics, and some things from science, math, technology, engineering and many fields of knowledge. In fact, most of my significant education happened on Internet, thanks to such projects.

I love the USA and the modern liberal western world who made such things happen. Hats off.

Disclaimer: I am from a third world country. $10 p.m. was an expensive thing for me for a large time.

PS: I hope to be able to contribute more to such projects soon. I do contribute a rather insignificant amount as compared to the scale of things.

I thought the issue is/was that site owners (original, or purchasing the domain afterwards) could via a robots.txt remove their site from the archive?

or has this changed and now no matter what happens if the archive crawls a site on a date it stays no matter if 10 years down the road somebody buys the domain and decides to retroactively erase everything?

My thanks to Jason and all, for every time I've found a resource I was seeking mirrored and preserved, for my use and for posterity.

I'll add that a lot of "older" pages seem to -- still -- be more useful than many newer ones. The archive isn't just about maintaining some record "for posterity". It proves useful in current circumstances, daily.

And that's not to mention their software library. Sketch (Jason Scott) seems to be the driving force behind it. As much as it's backed by ugly hacks (emulators compiled to JS.

They want to preserve the data.

How about this:

1. Prgram an app that you asks the user if archive.org could store, say 1 gig of encrypted data on your hard drive? It wouldn't be mandatory, but you could help if desired. It would just sit on your hard drive. That gig of data would be changing on a regular basis. (Big data centers could offer to take in data. Hell, they could have another tax right off at the end of the year.)

2. After all the data has been distributed around the world; the data transfer would start over again, but on different computers. In a short amount of time you might have millions of computers with part of The Internet Archive sitting idle on users hard drives. The end result is the users would be worker bees; waiting for the queen to call them home. (In the end, you might have 1000 computers with the same block of data on their hard drive. Why because computers don't last forever.)

3. If we had a catastrophe, once the new Internet Archive was repaired/restored; the data lying dormant on millions of hard drives would come home to papa in a orderly manner.

4. It would remind people of the importance of preserving history. It would bring more attention to The Internet Archive. It would bring in a sence of team. Why not try it until this 592c3 gets their donations?

5. Yes--this is off the top of my head. I would need to put more thought into it.

I agree with the idea of what archive.org claims to be doing but it doesn't seem right the way that they are going about it.

The exclusion specifically of any ISIS supporting articles and videos makes it seem that archive.org is not truly interested in creating an archive for future generations but is instead interested in creating an archive which supports their political/religious beliefs.

Cataloging and archiving Islamic State videos doesn't mean that one endorses their beliefs or supports the organization.

It's a shame that what could've been an organization for good has become a islamaphobic political organization.

War Is a Racket by General Smedley D. Butler (1933) wanttoknow.info

Must read. Was told to read it by a former Army pilot. Been telling everyone to read it since.

Reading the comments below, I come to understand that many are missing the point of the essay, or speech as it was intended originally.

For modern readers, Butler's words are not to be taken directly but in context. Butler's point is that war is a racket. That is it. Funny right. If you are to ignore all the details about the casualties and who said what and who did what, you are still left with the essence of the speech. War is a racket. Repeat after me :) If you instill the mindset that war is a racket then all the pieces fall into place. It becomes very clear that war has no regard for human life. That it is detached from reality of life and death.

"Eliot A. Cohen, an official in the George W. Bush administration who is now a professor of strategic studies at Johns Hopkins University, said that Mr. Obamas trips to Walter Reed may have been the reason, and that future presidents should avoid such visits.

A president has to be psychologically prepared to send people into harms way and to get a good nights sleep, Mr. Cohen said. And anything they do that might cripple them that way means theyre not doing their job." -- http://www.nytimes.com/2016/11/29/us/politics/obama-walter-r...

"theyre not doing their job" --- their job being what?

Be smart, war is a racket, and suggesting a president should not be worried about the lives of the people he harms is fucked up. Additionally, presidents should visit hospitals in Syria maybe. Maybe then they will not make the same actions.

doug1001 23 hours ago 4 replies      
this is extraordinary

i say this for several reasons. One, Smedley D Butler is one of perhaps just three former US Marines universally regarded as demi-gods (the other two are Sgt. Dan Daly and Gen. Chesty Puller). Their official photographs are everywhere, and statement alleged to have been made by them are quoted like scripture among active duty marines. Gen Butler aside from attaining the rank of major general, was awarded the Congressional Medal of Honor--twice. (Sgt. Daly, my personal hero, had two as well and a Navy Cross, the second-highest award in the USMC, equivalent to the Army's DSC; Chesty had no MoH, just five Navy Crosses, which is still pretty good).

So here he is at the end of his superb 33-year career, writing a book in which he declares that war is a Racket. And by "Racket" he is clearly using the term in the precise sense: "[a] service that is fraudulently offered to solve a problem, such as for a problem that does not actually exist, that will not be put into effect, or that would not otherwise exist if the racket did not exist."--in other words, what organized crime does.

> "Looking back on it, I feel that I could have given Al Capone a few hints."

from the OP (a except from the Book, which in turn was based on a speech given by Butler two years prior): "I spent thirty-three years and four months in active military service as a member of this country's most agile military force, the Marine Corps. I served in all commissioned ranks from Second Lieutenant to Major-General. And during that period, I spent most of my time being a high class muscle-man for Big Business, for Wall Street and for the Bankers."

Needless to say, i never heard about this book while serving in the USMC as a Sergeant.

second, this book was published in 1935--Gen Butler's indictment pre-dates not just the Vietnam War but WW II.

One of the reasons why I'm optimistic for a Donald Trump presidency is that finally Americas ugly policies have an ugly face to go with them. Every single one of Americas Presidents, from Obama to Reagan, JFK to both Bushes all maintained a veneer of respectability and decency. All of them cultivated a diplomatic and "statemanlike" appearance, all while continuing absolutely barbaric foreign policies designed to maintain American hegemony and appease industrial interests, no matter what the cost. Trump, on the other hand, refuses to play by this charade and indeed "tells it like it is".

American foreign policy can hardly become more profit-centered and evil than it has been post WWII, but I predict we will see a resurgence of voices critical towards it in the coming years because Trump places no effort in hiding behind pretty words and a wall of PR. The ugliness of American actions will now be apparent for all to see.

"But the soldier pays the biggest part of the bill"

I'm not sure how it was in Butler's time, but I've read that the overwhelmingmajority of casualties in modern warfare are civilians. It would seem to me thatthey are the ones who pay "the biggest part of the bill".

Not that I would deny that the people doing the mass murder can themselves becomethe victims of war. But I'd personally have more sympathy for civilians who are nottrying to murder others but are themselves murdered.

JFK and Reagan at least inspired the population, and I wouldn't mind seeing another similar president, but I don't think today's political climate could tolerate any of them today.

It's a shame.

Weirdly, the last two episodes are really the first two, so start there, the wrap back around to episode 1.

The problem is that you can justify almost any conflict as ultimately meeting these criteria. If you let someone else become too powerful isn't that a de facto threat to your home? If you don't defend rights abroad, don't you threaten the extinction of rights at home?

That's why we do rely on the morality of our leaders. Which seems to be ropey at best.

Coincidentally, I told my brother to read this last weekend.

Smedley Butler is a brilliant orator. He manages to distill social and political outrage/abuse into a language that the everyman can connect with, and without sounding like a populist communist sympathizer. He achieved the latter by often stressing the importance of individual as well as community action. He used the term "Americanism" do describe this socially engaged entrepreneur attitude.

"The only way to smash this racket is to conscript capital and industry and labor before the nations manhood can be conscripted." This is a great quote. Never gonna happen. But what a change that would make. If we instituted a "draft" of the financial and industrial systems, e.g. made them pay for war the way drafted soldiers pay-- without profit-- without choice-- we wouldn't go to war. The powerful and wealthy would never allow their profits to disappear into that kind of a void.

Tyler Cowen has written a lot about this:

"Individuals dont in fact enjoy being evaluated all the time, especially when the results are not always stellar: for most people, one piece of negative feedback outweighs five pieces of positive feedback. To the extent that measurement raises income inequality, perhaps it makes relations among the workers tenser and less friendly. Life under a meritocracy can be a little tough, unfriendly, and discouraging, especially for those whose morale is easily damaged. Privacy in this world will be harder to come by, and perhaps second chances will be more difficult to find, given the permanence of electronic data. We may end up favoring goody two-shoes personality types who were on the straight and narrow from their earliest years and disfavor those who rebelled at young ages, even if those people might end up being more creative later on."

http://marginalrevolution.com/marginalrevolution/2015/09/the...

Pervasive employee monitoring and feedback isn't costless. Some people will improve, others will get fired/quit find a new job, but there will be some who cannot take it at all. If losing a job wasn't so punishing economically and status-wise, it would take a lot of, but certainly not all, of the sting away.

However my nephew didn't have such a fun time. He was working for one of their warehouses in Kentucky and they were ruthless to the workers like him.

Amazon tries to trap people through control by visas, and they will go so far as to relocate people overseas to Seattle. They have a fucked up system where rank and file get the darwin treatment but management gets the rewards. They will pay bonuses around $250k, $500k, $1 million to senior managers, directors, and VPs respectively to abuse the shit out of employees. The "PIP someone who is trying to get away from their abusive manager" is their oldest trick in their book.

Following some of the discussion on this thread, I am constantly reminded of a priceless advice I got from a senior friend years ago.

When thinking about an employer, above a certain size threshold, never judge a company. Always judge a department. You don't work for a company. You work for a department. Above a certain (fairly small) size, the only thing you'll share with the employees in the other departments will be the domain name in your email. Everything else will be coincidental.

Having escaped from an abusive manager myself, I can imagine what this person went though. Managers that are skilled in the art are able to inflict pain without leaving much of a paper trail.

I did ask for (and got) professional help, including medication. There's only so much stress 24/7 that you are able to handle before you start to crack. Who knows what would have happened if I just tried to ride it out.

I'd have gone bananas if I had been placed in a PIP instead. This was one of the possibilities identified by my branch predictor, so I was collecting a mountain of evidence against said manager. Thankfully, it wasn't needed.

(I realize that nowhere in the article it says a manager was the issue, but corporate pattern-matching gets pretty good after a while)

Amazon screws employees in ways unseen in other companies. From the perspective of an engineer, this is a terrible place for people to work and grow. To list a few things:

- Equity vesting schedule is 5%, 15%, 40%, 40% over 4 years

- Relocation package is prorated for TWO years. If you leave after staying for a full year, you still need to return 50% of it.

- 401K matching only vests after working for 3 years. If you leave within 3 years, no matching for you whatsoever.

- No tuition reimbursement. Want to get a part-time masters in CS? Pay it yourself!- No catered food. No free soda. No free snacks. If you are hungry, you can eat at one of the shltty cafes.

- Obnoxious oncall routines. You are woken up 3:30am waiting for the event to be over. Why not automate things? Because replacing people is cheaper than building great software!

This is Amazon's mindset TOPDOWN. The root of the problem is that the leadership does NOT care about employees or technology. This is a retailer and a powdered Walmart, what do you expect?!

SDE 1 and SDE 2 are simply the slaves working at a sweatshop. Some of my co-workers are hired without onsite interviews. They do some video chat and they are hired at Amazon. They don't even know how to write bash scripts. Our team used to have technical program managers who can't even write a Python script. With simple things like running a command line tool, he cuts a ticket and let the engineers do it.

The managers at Amazon pocket bonuses and don't give a damn. They don't carry pagers and when they do, they just page lower level employees. The only reason people take offers at Amazon is that they can't get better packages from Facebook/Google.

There are no details why he requested a transfer, the reasons he got put on a PIP, and if he was mentally unstable or not, where these fairly common life events would cause him to contemplate self harm.

While by no means I mean to minimize this announcement, if the press was publishing an article every time a Coal plant opens in India, we would have an article every few days or so on HN.

Just to put things into perspective:

- A plant like Topaz, California generates ~1100 GWh/year. [3]

- "India was the third top electricity producer in the world 1272 TWh in FY 20014-15" [1]

- "India was the third top coal producer in 2015 with 283.9 Mtoe (7.4% global share)." [1]

- "Nearly 80% of total electricity generated (utility and captive) in India is from coal." [1]

So we're about at 3 orders or magnitude, in terms of generated electricity, between what you currently get from coal plants and this new Tamil Nadu plant. While the penetration rate of renewables is faster than coal [2], the same thing cannot be said of generated capacity. Globally an unit of power from renewables has a far lower EROI compared to Coal [4].

So I support what kumarski said below, this is much of a hype. If India wants to be serious about climate change, they should at least stop building Coal plants.

For the next few years we'll be opening a new coal plant each month.

To give you an idea of how far we are behind as an energy grid.

The US & China each Produce about 4000 Terawatt Hours Per a Year.

India is somewhere in the ~1500 Terawatt hours per a year.

To make up the difference we're going to burn a ton of coal, the worst kind of coal.

agentgt 1 day ago 5 replies      
I would like to share some thoughts on this based on experience of being a crusty old enterprise developer. The dashboard problem keeps coming back. I think the time might be finally coming for some dashboard framework to actually succeed.

A dashboard framework has been tried many many times. Here are some old ones just on the top of my head:

* Shindig aka OpenSocial aka Google Gadgets

* J2EE portlets

* OpenUSS

I'm not sure why Shindig aka Google Gadgets failed but one of the complaint we had on a product that I helped build that used Shindig is that business users did not want the complexity of customizing a dashboard. That is hard coded panels were good enough.

I guess just like many tech stuff (slack/irc, wiki) the timing and execution just wasn't right. I think now that might change given the plethora of devops, data driven biz, and generally improvement in tech awareness.

It would be nice if Cyclotron had some sort of spec (particularly language agnostic) but I guess that failed hard for the above.

For my own small company we use Kibana (the old one that doesn't require NodeJS), Grafana, and Jenkins.

Yes we use Jenkins as a dashboard. Jenkins is actually shockingly a good place for a dashboard because every time we build/deploy or kick off some kind of job we see the current status of stuff. I'm not sure why cloudbees hasn't taken advantage of this. I honestly think it is the best place to put devopsy like dashboards.

The other nice thing about Jenkins besides it actually kicking things off is the notification. IMO notification is almost more important and more useful than dashboards. The two should be not be far apart but for some reason in most systems they are.

Yet there shouldn't be any reason why a dashboard couldn't be rendered on them!

I wonder how Cyclotron performs with it's JS heavy front-end on those types of dedicated dashboard devices?

Here's the thing about Richard Stallman -- he's absolutely correct in all of his principles and all of his underlying thinking. He's as intellectually farsighted as anyone I can think of in tech. However, all of the movement around him and the resulting "outreach" efforts have been rather shortsighted in comparison.

Let's use environmentalism as an analogy. There is a place for an absolutist intellectual position, when it comes to the underlying science. However, much of the tremendous progress that has been made with respect to the global environment has been a tenacious "foot in the door, while they're slamming it" struggle, where allies and politics are vital. This is why I found the FSF animosity towards "Open Source" perplexing. If a group is advocating for freedom, I find it perplexing when they seem to be coercing me to be free in exactly the way they deem correct. While leadership is vital in any movement (I think that leaderless movements generally fall off the rails and tend to spawn extremist groups) one of the primary reasons leadership is vital is to set the tone and morality of the movement. A firm philosophical and intellectual grounding is also vital, but it can't stand alone if the tone and morality of the movement allows it to succumb to any human group's natural tendency towards jingoism. RMS always got the intellectual far-seeing right. In terms of tone and politics: fairly close to dead wrong. Basically, he could impress college aged me, then alienate working aged me.

Corporations need to be treated as if they could have radically different managers at any moment (because they can). The Best Company Ever of today could be bought by Worst Corporation In Existence tomorrow.

It essentially doesnt matter what a company is currently doing or promises to do or not do, if those behaviors are not legally binding. And even then, if you have to read a hundred-page document to figure out what the legal binding is, assume that the company has carefully placed a nice escape hatch somewhere in their legalese.

It was supposed to be true that if one vendor does something you dont like, you simply vote with your wallet and go to one that you do like. That works great when buying toasters. Yet now, with essentially your whole life tied up in one or two devices and key services like Internet being dictated by one company based on where you live, it is REALLY hard to just walk away from one crappy technology experience and find something you like better. This is a real sign that it is not a good idea to have so much technology powered by so few corporations.

I have no idea when this "law" was written or said, but I think this type of thinking--in 2016--is exactly the cause of what it's prophesizing.

Instead of thinking from "corporations vs. us", a better approach would be to think of humanity as a single entity.

I do understand that all this "open software" movement could have an impact because it was very polarizing and moved a lot of people. But in a world where open source is the norm, it should not be about fighting against corporations. The discussion should be on a higher level.

For example, you should think deeper about why it looks like: "While corporations dominate society and write the laws, each advance or change in technology is an opening for them to further restrict or mistreat its users".

Only when you look deeper into the corporation's motivations you'll be able to figure out a way to defeat this. Otherwise it just reads like a rant.

No, you can't just take a statement and call it a "law", even in a facetious sense.

Murphy's law, Betteridge's law, or other facetious laws are at least roughly formulated as "if X, then Y" (or sometimes "Y happens"), which mimics the structure of actual scientific laws. Stallman's statement is formulated as "if X, then maybe Y" (or "Y could happen").

Since many comments in this thread converge towards language pronunciation:

When people are learning how to draw, they typically have to learn how to "unsee". To quote Betty Edwards:

students beginning in art generally do not really see what is in front of their eyes that is, they do not perceive in the way required for drawing. They take note of what's there, and quickly translate the perception into words and symbols mainly based on the symbol system developed throughout childhood and on what they know about the perceived object.

Learning how to pronounce sounds in a new language is the same. A lot of people will pronounce foreign words with how their brain thinks it should sound, using their native language as a baseline. The trick is to try to get rid of any phonetic preconception you might have, and pronounce sounds as you hear them from native speakers. It takes practice, but it's a learnable skill.

(Which is why romanization of Asian languages, for instance, is a trap for new learners: if you're learning Japanese, the latin alphabet should have no place whatsoever in your learning. It's a tempting, but false path)

For drawing like for speaking, kids are naturally good at this. (except while language acquisition happens naturally for kids, deliberate drawing practice rarely does)

As someone who learned to speak fluently in a different language, I believe the trick is to study the IPA of both your native language and the one you want to learn. This is especially true if you come from a language like English which isn't a phonetic language.

It sets a common ground for you to work with. There may be some vowels that may be undistinguishable for both native speakers. However, you'll likely to come across some that requires a developed ear to differentiate the two. This is the reason why you probably have an accent. Focus on tongue placement, emphasis, change in pitch, etc.

Of course, this won't help much to actually speak in a different language, but for accents I found this method incredibly helpful. It's the micro side of things that most people overlook.

the window of mastering an accent closes once you hit your late teens. After that your brain cannot hear the correct pronunciation and merely maps it to closest sounding sound in you mental library. Once you can't hear it, you can't speak it. It is much easier and useful to learn the "flow" of the language than trying to make new sounds .

People always use colin Farrell as an example of adults who mastered an accent but forget that his native language is phonetically close to the language he is supposedly mastering.

This appears to be a legitimate ME neutralization.

The ME is purportedly placed in "recovery" mode:

 According to Nicola Corna, the current ME state should have been changed from normal to recovery.
Since the MEI interface is disabled (not visible from a PCI bus scan), there is no way to activate the ME at runtime, even after a full system compromise. It would still be possible to rewrite the BIOS flash chip with a new ME image, but the system would need to be restarted before the ME would read the changes.

I don't speak for the FSF, but it sounds like this is as close to an FSF RYF certification as any Intel CPU is going to get. FSF approval of a device requires that all user-modifiable software be Free Software. Previously, no recent Intel CPUs could be FSF certified as "RYF" because the ME chip would shut the system down after 30 minutes. (Side note: no recent Intel CPUs can be considered "stable" without microcode updates which also violate the FSF's RYF guidelines.)

* A set of software tools: Check

* Unauthorized user: Check Caveat: user is not authorized by you, but by someone else (Intel)

* Gain control of a computer system without being detected. Can access your machine while it appears to be "powered off" but plugged in. Has full access to RAM. Can draw undetected on top of screen. Can read screen. Check.

So. Does this qualify the Management Engine as a rootkit? It meets the definition. Just because the rootkit is installed by the manufacturer doesn't make it less of one.

I appreciate that Warren didn't let Stumpf talk his way out of taking any responsibility for the actions of his employees and made a clear argument as to why he should be held accountable. Unfortunately, it seems the primary reason he resigned was because the public outrage was loud enough. It seems that until CEOs are personally held accountable via fines or prison (as Warren suggests) we won't see a very big change in their actions. He benefited personally from the policy he implemented, but ignored the negative consequences. The bank is fined, but he is not and keeps his bonuses.

What do the libertarians say about this theft? While I understand the idea of the free market, I don't see how that would have protected the consumer in this case. The CEO has millions of times the power of the average consumer, and can harness thousands of people to his agenda.

The consumer is left to either (a) pay the "idiot" tax of being stupid enough to sign up for a thieving bank, or (b) rely on the government to protect his best interests.

While I have severe misgivings about the efficiency and corruption of large government, I find it hard to argue that a perfect "free market" would be better for the consumer.

In pushing for jail time for this particular CEO, Elizabeth Warren is barking up the wrong tree. Stumpf made mistakes in setting incentives and monitoring staff culture, but there is no evidence he committed fraud. The bank overcharged customers $2 million dollars and paid a $185 million settlement. That seems reasonable to me.

More worryingly, the bank also seems to have harassed and blacklisted whistleblower employees. No doubt it will have to pay a hefty settlement and class-action lawsuits, but again the CEO is guilty only failing to monitor bank culture. There was nothing malicious or criminal in his actions.

The number of fake accounts created by the bank - 1.5 million! - is irrelevant. I run a business and can create a billion customer accounts in seconds without harm to anyone else. What matters is how much damage the bank did to others - in this case the bank has already paid a fine proportional to that damage.

Instead of going after a hapless CEO and a company that has already paid a huge settlement for a relatively small error, Elizabeth Warren should focus her attention on banks which overinflated the value of their mortgages before selling them on to other banks or Freddie Mac and Fannie Mae. In such cases we're talking a fraud involving billions of dollars, that led to worldwide financial recession, and where perhaps the CEO had direct knowledge of the fraud.

I watched Stumpf testify in front of the Senate Banking Committee, and while I agree that (from what I saw) he should be held accountable, what I don't understand is why the right venue for it is the Senate instead of the Judiciary.

Warren clearly thinks that Stumpf wasn't just doing a bad job, but that what he did and didn't do was criminal in some way (eg the talk of jail time, comparisons to Enron in the article). The CFPB settlement also indicates that there was wrongdoing, at least on the part of Wells Fargo the corporation.

Isn't the right thing to do to prosecute Stumpf in court? The testimony seemed to me to have no purpose other than to put Stumpf "on trial", and it led to damaged PR and his resignation, but it looked like a "trial" without due process protections like knowing what exact charges he was facing. Another missing protection I was particularly disturbed by was how often she would cut him off and not allow him to defend himself (yes, his answers were clearly evasive, but it still isn't fair to do that).

I absolutely love Senator Warren. That being said, the notion that the stock price of Wells Fargo could be significantly impacted by this scheme (which is central to Ms. Warren's argument) is not well founded.

Wells Fargo makes 86 billion in revenue per year. Even if 10 million accounts were made and each made a thousand dollars -- (incredibly generous) ... over the course of 5 years this accounts for 1 billion in revenue or 200 million dollars per year. Annualized it is much less than 1% and would not inflate the stock price.

These guys definitely made a mistake. It wasn't calculated fraud. It was bad incentive setting. Politicians like Warren don't intuitively understand how hard it is to actually control a group of thousands of middle-class workers and get them to do things.It is not easy to govern ... sadly politicians are the least knowledgable in what it takes and they hurt good people like Stumpf (I trust his leadership and qualities because he was appointed by Buffett).

WF stock dropped a bit prior to the hearing and I bought as much as I could. Luckily most of Wall Street is smarter than such politicians and it paid off. Thanks Senator Warren.

What I would like to see is politicians be held to the same accountability as these guys. That would be hilarious. I wonder how well Obamacare would do if we could actually measure results based on metrics.

Our society needs people that can blend business acumen with the spirit and heart of people like Elizabeth Warren. Only Buffet or Gates come to mind.
