I'd like to welcome the github ops/dbas to the club of people who've learned the hard way that automated database failover usually causes more downtime than it prevents.

Here's sortof the seminal post on the matter in the mysql community: http://www.xaprb.com/blog/2009/08/30/failure-scenarios-and-s...

Though it turns into an MMM pile-on the tool doesn't matter so much as the scenarios. Automated failover is simply unlikely to make things better, and likely to make things worse, in most scenarios.

Here are the makings of a bad week (Monday of all things)

- MySQL schema migration causes high load, automated HA solution causes cascading database failure

- MySQL cluster becomes out of sync

- HA solution segfaults

- Redis and MySQL become out of sync

- Incorrect users have access to private repositories!

Cleanup and recovery takes time, all I can say is, I'm glad it was not me who had that mess to clean up. I'm sure they are still working on it too!

This brings to mind some my bad days.. OOM killer decides your Sybase database is using too much memory. Hardware error on DRBD master causes silent data corruption (this took a lot of recovery time on TBs of data). I've been bitten by the MySQL master/slave become out of sync. That is a bad place to be in.. do you copy your master database to the slaves.. that takes a long time even of a fast network.

I know that they have to be apologetic like this, but the simple fact is that GitHub's uptime is fantastic.

I run http://CircleCi.com, and so we have upwards of 10,000 interactions with GitHub per day, whether API calls, clones, pulls, webhooks, etc. A seriously seriously small number of them fail. They know what they're doing, and they do a great job.

If Github hasn't gotten their custom HA solution right, will you?

Digging into their fix, they disabled automatic failover -- so all DB failures will now require manual intervention. While addressing this particular (erroneous) failover condition, it does raise minimum down time for true failures. Also, their mysql replicant's misconfiguration upon switching masters is also tied to their (stopgap) approach to preventing the hot failover. So, the second problem was due to a mis-use/misunderstanding of maintenance-mode.

How is it possible that the slave could be pointed at the wrong master and have nobody notice for a day? What is the checklist to confirm that failover has occurred correctly?

There is also lesson to be learned in the fact that their status page had scaling issues due to db connection limits. Static files are the most dependable!

druiid 2 hours ago 1 reply      
Well, I have to say... replication related issues like this are why I/we are now using a Galera backed DB cluster. No need to worry about which server is active/passive. You can technically have them all live all the time. In our case we have two live and one failover that only gets accessed by backup scripts and some maintenance tasks.

Once we got the kinks worked out it has been performing amazingly! Wonder if GitHub looked into this kind of a setup before selecting the cluster they did.

The part of this post that really blew my mind:

  We host our status site on Heroku to ensure its availability
during an outage. However, during our downtime on Tuesday
our status site experienced some availability issues.

As traffic to the status site began to ramp up, we increased
the number of dynos running from 8 to 64 and finally 90.
This had a negative effect since we were running an old
development database addon (shared database). The number of
dynos maxed out the available connections to the database
causing additional processes to crash.

Ninety dynos for a status page? What was going on there?

From what I can gather, the White House didn't explicitly ask for the clip to be removed. Rather, they suggested the clip might violate YouTube's own terms of service.

From the article:

> White House officials had asked Google earlier on Friday to reconsider whether the video had violated YouTube's terms of service

Still, the net effect is the same. The gesture was made with the goal of having the video removed from YouTube. It's unfortunate that our administration went down this path at all.

Google is a business and it has every right to operate as it sees fit. Being a company that is headquartered in the US I can't believe it would censor this video at all in any jurisdiction. It's not out of character for them considering the lengths it went to appease China but I don't think that was the right decision either.

I would hope that if I was ever faced with a similar situation I would choose based on my conscience not on ignorant local laws, what was best for the business, or what seemed to be the easiest choice at the time.

Cost of the Uniloc Lawsuit x-plane.com
113 points by mmastrac  5 hours ago   30 comments top 11
creamyhorror 5 hours ago 3 replies      
The general background, necessary reading for basically all of us:


Specific lawsuit details:


Hilarious, it's a patent troll called Uniloc suing a guy for implementing a license-check-with-a-server in his Android app - apparently the one provided by Google for use in Android apps.

LANGUAGE OF THE DISPUTE: Paragraph 12 of the lawsuit states: ”Laminar Research is directly infringing one or more claims of the '067 patent in this judicial district and elsewhere in Texas, including at least claim 107, without the consent or authorization of Uniloc, by or through making, using, offering for sale, selling and/or importing Android based applications for use on cellular phones and/or tablet devices that require communication with a server to perform a license check to prevent the unauthorized use of said application, including, but not limited to, X-Plane.”

Section 107 of the patent, which they claim I violated, contains: “107. …code for verifying the license data stored on the licensing medium by communicating with a registration authority having verification data….”

These guys seriously need to be beaten down. Their website says:

“In the device recognition space, for example, we believe that we have uncovered a billion dollar market … And it fits our straightforward development model. Look at many ideas. Pick an outstanding one. Patent it. Commercialize it. Reap the rewards.”

Either they were really careful with the patent application phrasing, or the PTO flubbed this one.

THE PATENT IN QUESTION: I'm reading the actual patent and seeing that it's about a license system which is in 3 parts: device, "portable license medium", and registration authority (presumably a remote server).


MAIN IDEA: The primary claim is that the device checks the data on/from the license medium and compares it with verification data from the registration authority. The data may be a hash of the license data; it may be encrypted by a private-public key system; it may contain hardware identifiers so that the authority can check if the hardware is on an authorized list; it may be updated with new data from the authority; it may be limited by an expiry date; so on and so forth.

It goes on to talk about securing the licensing medium and data by means of a double verification process (through a "license manager").

LICENSING MEDIUM: The definition of the licensing medium:

The licensing medium 120 is a portable component that contains information concerning the software or other licensed electronic data that the user is authorized to access. When a user seeks to access a vended piece of electronic data, the client program communicates with the licensing medium 120 to verify that the user is authorized to access the electronic data.

In general, the licensing medium 120 may be any type of portable electronic data storage medium that has a unique, unalterable serial number or other form of identification that can be transmitted electronically. Examples include smart cards, memory sticks, magnetic strip cards, floppy disks and other removable computer storage media. The licensing medium 120 and the electronic device that uses the licensed electronic data need not have a wired connection. A wireless connection, e.g., an infrared or radio frequency (RF) link, may be used.

DOES THIS PATENT APPLY?: In general, this seems to be a patent on a license system involving a separate, "portable" license module (like a dongle or smartcard) that provides license data and can be updated with new license data from the server. Putting aside the question of whether this deserves a patent in the first place, I wonder what about the guy's Android app involves a separate, removable license medium. What's their basis for suing?

Especially in the light of:

Speaking for Laminar Research, we used only the technology that was provided to us by Google for copy protection in our Android App ‘X-Plane'… we used exactly the copy protection Google gave us! And, of course, this is what Google provides to EVERYONE ELSE THAT IS MAKING A GAME FOR ANDROID!

KEY CLAIM: And here's the claim at the heart of the dispute, which I should've gone to at the start:

107. Computer code executable on an electronic device to prevent unauthorized access to electronic data stored on the electronic device, the computer code comprising: code for storing license data on a portable licensing medium configured to communicate with the electronic device; code for determining whether to allow access to the electronic data based on the license data; code for verifying the license data stored on the licensing medium by communicating with a registration authority having verification data; and code for providing updated license data received from the registration authority to the licensing medium.

This very clearly says that the license data is stored on a "portable licensing medium". If they're referring to license data stored in the internal RAM or SD card of a smartphone, then it collapses to the traditional license-data-and-server model and it doesn't make sense to talk about a portable licensing medium any more.

It's patent nonsense, literally.

If Uniloc wins this lawsuit they will have a precedent with which to sue every app developer on the Android Marketplace who uses the Android License Verification Library. Given how this can be a crippling blow to the Android Marketplace, I'm interested to see what Google's reaction will be to this lawsuit.

I was surprised to see that this lawsuit seems to be about copy protection, specifically Android app signing, not anything specific to flight simulators.

The specifics of the suit were two clicks away from the linked page:

This seems strange; does android app signing even use "communication with a server to perform a license check"? That sounds more like serial/license number verification.

For many states where companies are incorporated, much of this is often required to be released as public information for articles of incorporation and annual report filings--even for privately-owned corporations.

It seems to me that it would be very much in Google's best interest dig some change out from under their sofa cushions and provide legal support for these developers. There should be no question that the patent will be knocked down, but knocking it down will take money, and it would behoove Google to let their developers know that when the patent trolls come a-knockin', they won't be left on their own to defend their use of basic API calls.

That's one hell of a story of hustle. What you've discovered, I think, is (paraphrasing Steve Jobs [1]) that the world around you was built by people just like you. You've seen behind the curtain, and there's no wizard, only some dude who's no smarter than you are figuring it out as he goes along. Kudos to you for discovering this at such a young age, I didn't get it 'till my twenties.

My advice to you: put the last section of your article out of your mind. You've achieved some pretty amazing things, focus on that, and keep shipping. Comparing yourself to others is a path to insanity, there will always be someone who has accomplished more, done it faster, made it look easier, etc. And one more thing-- you're never too young to do anything, but keep in mind that with age comes experience. There are people out there (like the ones you mentioned), who have been where you are before, have faced similar challenges, and overcome them. No matter how early you start, you'll always have more experience the older you get, so continue to seek out the advice and mentorship of those who have walked the path before you.

I believe that entrepreneurs could do well, generally, by looking for opportunities in industries that are dominated by private-equity players.

If an industry is overweight PE, you can bet that the market analysis looks fantastically attractive (competition isn't too fierce, suppliers have little power, buyers have little power, not many substitutes, and little perceived threat from new entrants). If a clever entrepreneur can render that last condition false and enter that market, that entrepreneur has the opportunity to shrink and consolidate a $huge market that's owned by PE players into a $smaller market that is owned by the entrepreneur.

PE controlled competitors will, generally, not be particularly agile, because PE tends to capture value by leveraging the heck out of a currently viable business model. It's a model that works really well as long as base assumptions hold true, but startups can ruin that for them.

There are all sorts of outlets for reasonably priced, what you see is what you get mattresses: Sam's Club. Costco. Ikea. You can get a decent name brand mainstream mattress for ~$500.

The problem with mattresses is that it's a product where you need a salesman. There's a bunch of different products that look similar, but have significant differences. You want to match the customer with what they want (or tell them what they want) so that they don't return the thing.

Plus, there are some inherent logistical differences between a pair of eyeglasses that can be dropped in an envelope and shipped to anywhere in a day or two. Distribution and warehousing is expensive, the product needs to be delivered quickly (and picked up if the customer is displeased).

There is a market for discount mattress sales outlets on the internet -- but just as online furniture and appliance outlets haven't "disrupted" the market, mattresses online are unlikely to either.

eastdakota 6 hours ago 0 replies      
The core problems of the mattress industry (which are not present in eyeglasses industry) are the high costs of shipping and expensive warehouse costs.

Given these, Bed In A Box (http://www.bedinabox.com/) started with what seemed like it could be a potentially disruptive business model. They make-to-order mattresses (will even make custom sizes) and ship Tempurpedic-like memory foam mattresses directly to you via UPS. They suck all the air out of the mattresses so the boxes they come in are reasonably sized. Inside the box, there's a backpack-style sack which makes the mattress easier to carry. I hauled a Queen-sized mattress up four flights of stairs easily.

I've purchased two mattresses through them and they are high quality and extremely comfortable. The first purchase they were easily 50% the cost of any quality mattress I could find elsewhere (including Costco, Sams Club, etc.), especially if you factored in the cost of delivery. I was surprised that when I went to buy another mattress from them their prices were markedly higher.

I wonder if consumers were concerned that the low prices indicated low quality (not the case in my experience) or if they were unable to get the volume to sustain a low margin, high velocity business.

If you attempt this, I suggest you make a deal with a motel chain: When a customer checks into a room, they discover a little sign on the bed. The sign says, "Like this mattress? Get a brand-new copy delivered to your home for $X00 by visiting mattressr.com and entering bed code MEDIUMSOFT-23."

While you're disrupting the mattress industry, please consider re-thinking the King form factor. Changing the aspect ratio by just a few inches would make it perfectly square, which allows for you to rotate 90 degrees as well as flip, so the whole thing would wear out more evenly.

As an extra bonus, this would make putting sheets on easier as there's no wrong way (short of inside-out, I guess).

silverbax88 6 hours ago 2 replies      
Having worked for one of the major mattress firms, there are truths in the article, but also some serious mistakes.

The pricing structure, where they hide the models by using different names across retailers, is 100% true. They absolutely do that to prevent price shopping.

The markup math is off. Mattresses are a high margin business, but most of those mattresses you see in specialty retailers are not built until someone buys one. You see, those mattresses are custom to the customer - from the tick (stitching pattern, which creates a firmer or softer surface) to the foam density, to EVERYTHING. It's like ordering a car where the car is measured to a specific person's height, weight and engine preference. You can imagine what a returned mattress is worth. Pretty much nothing. The margins have to cover all of that. Are the margins good? Yes. Would a small company be able to cut their margins to make one-off custom mattresses and compete? ...maybe.

Finally, there are retail outlets - Costco, Ikea, that buy from those mattress companies in bulk and sell generic mattresses much cheaper.

So, yeah, there's some market there but not as rich as some might think.

I'm not sure if you can count this as a startup, but I bought my King-sized Sleep Innovations (memory foam) mattress with Amazon Prime for $530. And if I wanted the less-think 10" one, it would be $400.


The damn thing was ~100lbs in a giant box, and I got it shipped to me free. It's super comfortable and well worth the money - remember you sleep for like 25% of your life.

Mattresses seem like less of a specialty-item than eye glasses, so I wonder if big online retailers like Amazon can just cut out the middle man and service 80-90% of customers?

ryanwaggoner 7 hours ago 1 reply      
Like any startup idea, there will be objections. Shipping mattresses is expensive, people want to lie on them first, mattresses require research and development spending to develop, a mattress purchase only happens once a decade, etc. All these objections might be right, but they all sound surmountable.

They might be surmountable, but that doesn't make this a better opportunity than a lot of the other opportunities out there, especially for a startup. The costs involved with disrupting the mattress industry as a manufacturer AND retailer are better left to a larger company. Like IKEA, as the article itself pointed out.

"By the time a customer buys a mattress, it costs them ~74% more than the production cost of the product."

I'm not arguing that the mattress industry isn't ripe for disruption, but very rarely is value delivered directly related to the cost of production.

COGS is often difficult to accurately estimate (how much do you allocate R&D and other overhead?).

An iPhone 5 may only contain $110 worth of silicon, but the value delivered is a lot more than the raw material cost. Jony Ive's salary represents a tiny fraction of each iPhone, but his design and influence represents a significant chunk of the profit.

There are lots of stories like this. Many of them are worse; at least you can imagine that the UK is holding these addresses in reserve. There are companies with giant allocations that are holding them so that they can give every desktop and every printer in their enterprise a routable address; others are doing the same thing, but also operating flat, unrouted networks.

More evidence for the core problem: fiat allocation doesn't work. If there was a functioning, liquid, accessible market for advertisable IP prefixes, you wouldn't have to convince anyone that a /8 was worth $1bn; it just would be.

forgotusername 10 hours ago 2 replies      
I'm not sure about the definition of 'unused', just because a network is not visible from the Internet and has no publicly registered ASNs doesn't mean its numbers are not in private use (which AFAIK, was always a legitimate use-case for getting an allocation, and in many ways preferable to reusing RFC1918 space).

Added to that, even if it was seeing only minuscule internal use, the UK government's IT project reputation suggests the renumbering would cost at least as much as the block would sell for, assuming the project would even complete prior to the entire planet properly migrating to v6 and the block losing its value.

No doubt part of the strategic IP reserve :-)

There are a number of ways the IP addresses can not appear to the outside user and still be used as several have mentioned, and of course they can be for some project that isn't yet 'done' (the Coast Guard had a huge block like that as I recall) but the more interesting bit is to track the cost of getting an /24 network its inching up.

And that's ignoring the possibilities that a) it's being used internally by its legitimate owners b) it's being used internally by other people. T-Mobile were seen to be (mis)using the /8 that belongs to the UK MOD for their internal networks, I wouldn't be surprised if they were doing that with this as well.

There aren't that many IPv4 addresses. There are no easy fixes. Just move to IPv6 already.

How many mobile phones made per day that support some form of internet access and how many of those use IPV6?

Scary thought is it not!

The first real opertunity to move to IPV6 in any way would be mobile smartphones and there like and yet that is not happening. It realy is a case of the ISP's and mobile telco's that need to start initiating the IPV6 move and until they do nobody will be dragged into following.

Maybe if it was illegal to sell devices that don't at least support IPV6. But of a messy situation when you can buy devices made brand new that still dont offer IPV6 support, criminal realy.

Still when you look into the history of British railways and the better modern alternatives you can see how some legacy designs just carry on with there limitations of capacity oversight.

Another aspect is cunsumers have in many respects forgotten how to complain to a company and let there frustrations out on the internet in area's were the companys offering the services will completely fail to notice and allow you to complain and vent of without them even knowing or indeed having to care.

How many of you have asked there internet service provider if they support IPV6 or indeed what there plans are to offer it? Reason I ask is that I can bet it's lower than 1 in 100 or indeed 1 in 100,000. I can't even recall any one of my friends or anybody I know or have dealing with ever mentioning they had made such an enquiry. I know I have, please tell me I'm not alone at least.

This could be a biggie. IE8 is the last version that works on XP, which I'm sure a great many corporates are running.

That said, if you're using Google Apps, you're probably not so averse to installing Chrome for your users.

Imagine that you're in charge of a small/medium sized business , stuck on Windows XP and some old email system. You've just persuaded the managers that "The Cloud" isn't so bad, and they've migrated everything over to Google Apps.

Now Google have just given you 8 weeks notice about support for IE8. Unlike traditional software, after this date you're screwed - you can't just not upgrade, you're actually cut off from the software you were planning on using.

Now, you can probably install Chrome or Firefox. If you're lucky, that won't cause any problems elsewhere.
But what happens next time? If Google decide that they don't want to support any client on XP, or perhaps the iPhone? What do you do then?
When this starts happening over the next couple of years we'll start seeing a backlash against the current trend towards the cloud.

It delights me to see how much polish Stripe put on everything they do. This is a basic feature, sure, but it seems as though it's been implemented extremely well. Even their blog announcement is extremely well-designed.

Stripe's attention to detail seems to permeate everything they do - from their homepage graphics to clear documentation. It's difficult not to compare this to PayPal, whose recent, much-trumpeted "redesign" only amounted to updating the front-facing portions of the site. It remains to be seen whether Stripe can keep this up as they scale, but it seems as though they've developed a great internal company culture that should give them a good shot at it.

I have a hard time being overly sympathetic here. complaining about building from source and can't get profiling tools running? Building code is being a developer, and osx is no different that any other unix variant, it has its own toolsets, like dtruss, shark etc. I don't get why gprof doesn't work for you, it works fine for me on osx.

this just seems like a lot of whining. If I wanted to debug a process that would occasionally get into a tight loop I'd run it under the debugger and break into it when it was peaking on the watt meter. A developer isn't just a programmer, the difference is that a developer can program and work the system, use the tools, debug the code, tune the kernel, etc etc.

cwzwarich 5 hours ago 1 reply      
The best way to use DTrace is by writing your own DTrace scripts rather than using dtruss or another wrapper.

Also, OS X does have a command similar to 'strace' called 'trace'. The simplest way to use it is like this:

  $ sudo trace -L <filename>
<terminate with ^C>
$ trace -R <filename> /usr/share/misc/trace.codes

That will print out a formatted list of events with timestamps, etc. BSD system calls are formatted with the 'BSC_' prefix, and Mach system calls are formatted with the 'MSC_' prefix.

If you run 'trace -h' it will tell you about more options for filtering, tracing for a fixed period of time, etc.

This way my primary OS stays as clean as possible (text editor, browser, fusion) and my VMs can be my messy playground.

Don't get me wrong, brew and ports are great but their very existence makes we wary of venturing too far down the rabbit hole of development directly on OSX.

I have used Instruments.app for my programming and I've used Valgrind, and there have already been two cases that dtrace (the provider that Instruments uses) has found memory leaks in my programs that Valgrind did not complain about, nor care about.

As for tracing system calls, dtrace is extremely powerful, and I much prefer it over strace where I a lot of times get a lot of garbage and have a hard time slimming down the output. I bet it comes down to what you are used to, and this guy is used to his Linux developer tools, whereas someone like myself would feel lost without dtrace, ktrace (trace on Mac OS X), sample, and various other tools that I use on a regular basis.

I think as many developers have been waiting for dtrace on Linux, which imho is a lot nicer.

It is mostly a question of what you're used to. To some extent the raw dtrace interface is a lot more powerful than Instruments though, so unfortunately you have to learn it before you can take advantage of most of the power of dtrace.

My Life as a TaskRabbit businessweek.com

I had a bad experience as a TaskRabbit buyer. There was a dispute between me and the task worker as to whether the task was complete. The worker went ahead and marked the task as complete and TaskRabbit deducted my credit card. The dispute resolution process was a convoluted and manual process which I didn't have time for (which is why I was using TaskRabbit in the first place). It wasn't a huge amount of money so I let it slide.

I can see why TaskRabbit might be biased towards paying for the task automatically after the agreement has been entered, the alternative would be to make it easy for the buyer to screw the workers over, but it seems like they probably need an easier dispute process or they'll lose the buyers, I know I'm not using them again. I guess the worker ratings is supposed to help with this but I couldn't quickly figure out how to rate the worker and TaskRabbbit didn't make it easy by sending me an email about it or something like that, so I just gave up.

The Antivirus Era Is Over technologyreview.com
11 points by olalonde  2 hours ago   2 comments top 2
andreasvc 4 minutes ago 0 replies      
The fundamental problem is that anti-virus software operates on the principle of enumerating badness: a list of known viruses and their signatures, a list of suspicious patterns in binaries such as obfuscation techniques.

OSes should move to the opposite strategy, enumerating exactly what is allowed, and dropping anything else by default. The challenge here is that the granularity should be small enough for this to be effective, but on the other hand this gives configuration overhead for the user. For example, the firewall could enforce that only the user's preferred email application is allowed to send and receive mail. Currently the permissions in plugins and smartphone apps are too broad to be meaningful, but they're already experienced as a nuisance, so it's a difficult problem.

thirsteh 57 minutes ago 0 replies      
Anybody who's ever thought about how an antivirus product works has come to this conclusion: Antivirus will detect software that does things that are known to be bad, but not software that does things in a new way. Depending on the level of sophistication of the antivirus solution, that either means a completely black-and-white distinction between what matches what is essentially a rainbow table of MD5 signatures and what doesn't, or more complex binary analyses like what kinds of actions an application binary performs, or what IP address ranges it attempts to establish a connection to.

Now, this doesn't mean that antivirus is useless, or that the antivirus era is over--by the logic of this post, the antivirus era was over the minute it began. What it means is that antivirus is a tool that helps protect you against "stupid"/mass malware, but not a tool that gives you any kind of "complete" or "100%" protection (although every AV vendor will certainly try to convince you that their products do), and this is particularly true--today as it was 10 years ago--when it comes to malware that isn't widely distributed, or, put more fashionably, "targeted malware" and "advanced persistent threats" (hence: malware which belongs to a "family" that hasn't been caught, analyzed, and added to a binary/behavioral signature/heuristic database of some kind beforehand.)

Great work. I'd love to see these as TextExpander snippets. I might go ahead and do this this weekend…

EDIT: A thought I forgot:

I used to be a Bootstrap hater, but now I'm quite enamored with the project since a good SASS port has been maintained.

Bootstrap's biggest accomplishment (aside from its mere existence) is that it placed in the hands of a lot of different people " devs, designers, newbies, etc " a collection of modular css patterns and clean, semantic markup examples, like the ones you see on this link.

"But your markup shouldn't be littered with presentation classes!!!" " Bullshit. Your markup definitely shouldn't look like the mess of classes you find in Drupal output, but <div class="navbar">…<ul class="nav"> are a sane way to markup page elements. These classes say what the elements are, and could be styled an infinite number of ways depending on what kind of device its displayed on.

Likewise, Bootstrap's CSS is an excellent way to learn modular CSS patterns. ".dropdown {}, .dropdown-menu {}" is a much better approach than something like ".dropdown ul". What if that UL changes? "UL is a lousy element here!" says a future dev on the team.

I'll agree that .pull-left and .span-9 are terrible, but not everything's perfect. It'd have to use SASS instead of LESS before it was perfect, anyway ducks.

Edit: I think this is a wonderful idea, and would use it, and can't wait for them to iterate. What I wrote below is intended to be constructive feedback.

I was ready to go for this, but $25 per slide doesn't work for me.

My deck is currently 30 slides. They're mostly low-content placeholders, many of them having 3 words or less, and they could all be handled by picking a nice theme, with maybe some minor tweaks.

However, some slides are content-heavy and could be optimized for attractiveness and "usability". And some will have to be redone because they make no sense or something.

So I could totally see paying for a customized theme and pallet and fixing the content-heavy slides and minor tweaks on the other slides, but that's not $750.

Also, 5 days sucks. Everyone I know always makes slides at the last minute. I'd could see paying 30% more for same day, or 50% more for 1 hour delivery though.

Does anyone know if the tip carbon monoxide was oxygen toward the probed surface or carbon? I wonder if using the same atom to probe as be probed is part of the resolution enhancement.

This seems to have been rumbling on for some time now - at least for the past five years or so.

My OS supports IPv6, my home router supports IPv6, but at no point have any of the home ISPs I've used (three in the past five years - BT Internet, Be and Origin Broadband) made any mention of any sort of IPv6 support.

I'm not au fait with the workings of such huge operations, so is there any reason for ISP adoption of IPv6 to be so sluggish? It's not like it's been an overnight thing. I'm aware it's unlikely to be a simple case of flipping a switch, or installing a new software package - but we do appear to be approaching an IP crunch.

Are there any consumer ISPs that do offer customers a block of IPv6 addresses for use, rather than (or as well as) a single IPv4 address?

I'm afraid of the possibility that instead of adopting IPv6, internet providers will just switch to ISP-wide NAT, making the internet even more asymmetric than it already is.

For those of you curious about IPv6, and wanting to experiment with it at home or in the office, have a look at SixXS[1] and Hurricane Electric IPv6[2].

They both offer free IPv6 "tunnels" which can be used to provide IPv6 to your home/office.

We use SixXS in the office, and the tunnel has been alive without issue for 83 weeks and counting..

(P.S. SixXS is probably the easier choice if you have a dynamic IP, or are not setting the tunnel up from your router directly..)

I'm still stuck on an IPv4 connection at home, in Britain. My phone still can't get IPv6 on mobile internet. My VPS host still doesn't support IPv6 on my server. And PHP still fails to properly parse some types of IPv6 address.

Things have got better, sure, but don't say it's almost gone. Far from it.

Yep and nothing will be done by ISPs until they are all completely gone (and maybe not even then, scarcity is good for business).

IPv6 is just like the transition to Python 3: it'll happen... eventually. But the only people with an incentive to put the hard work in are people who are genuinely enthusiastic about the transition. Everyone else is sticking it in the too-hard basket.

Hey 2004 called, they want their headline back.

When you consider the ability for inter-RIR transfer of networks, not to mention the market being developed (already released?) by ARIN (do other RIRs have markets?), and you've got a great recipe for a run on IP addresses.

I know these folks are well-meaning but I find these constant "warnings" to be insulting. What people really need to be aware of is that the folks making decisions of how the internet should run, "the experts", are not always as smart as they think they are. They make mistakes. And it's hard to get a bunch of know-it-all's to agree.

It's also hard to get the entire `net to switch their behaviour, and adopt something that is incompatible with IPv4, without telling them what benefit they will gain by doing so. Can you blame them? But the "experts" and their zombie followers sure are trying.

IPv4 works. NAT works. NAT can be traversed. So what is the problem exactly?

As a home user, I can set up my own NAT'ing scheme with private IPv4 space far easier than I can learn to deal with the added complexity of IPv6.

OK, now I will get skewered by IPv6 fanatics. How many of them are getting paid to do IPv6 consulting work?

IPv4: It Just Works.
"Experts": They make mistakes, just like everyone else.

Now, let's hear from the "experts".

Sam Aaron, the guy who has done a bunch of screencasts with Overtone (and his emacs/dvtm config), and used it to create this emacs config setup, has used the same effect on pretty much everything. It really does add an element of coolness to the mix.

I've been using emacs live for a bit. It's great. It bundles some nice plugins and has sane defaults. The cyberpunk colour scheme is cool. It has some nice personal touches on the scratch buffer.

The downside is that the structure puts far more emphasis on maintaining the structure than adapting your config. If you want to keep it solid you can't use package manager without some changes, or (configure-group).

You might get the odd issue with the bundled plugins (auto-complete loved lisp and file system traversal but hated other languages), but for a "I want to live code and I want it to WORK" config, it's bloody good.

oh i like, how does this compare to pd and max/msp, apart from the fact that those are visual.

it seems that the overtone guys want to add a visual display in the future. but most comparisions of supercollider and max/msp are mainly focused on the frontend.

is there anything i can do with max that i can't with sc besides looking pretty? (although i do prefer a nice editor to a visual thingie)

Network effects are not indefensible. I don't understand why so many people in the bay area think that network effects are impossible to break in. Here is an example. Orkut. All my friends including myself were on Orkut in 2004/2005. By 2008 everyone moved to FB. Why? Orkut had horrible UX and buggy system. FB was breath of fresh air compared to that. Even though Orkut has superior privacy features (I still say they had best privacy features for any social app). FB is moving in that direction. It's quite buggy system and if FB must address the overall quality of application. It looks like Orkut in 2007.

One lesson from reading this text is: if your site has googleable content, it will not decay as fast as if you rely on (semi-)active following. Seems quite obvious when stated this way.

There are various historical examples of various online networks. The one I began with in 1992 was the Prodigy commercial online network (which I had actually tried out as early as 1989). My paradigmatic example of an online network that faded away is AOL, which is still in business. My prediction about Facebook, posted previously here on HN, is "Facebook will go the way of AOL, still being a factor in the industry years from now, but also serving as an example of a company that could never monetize up to the level of the hype surrounding it." I could be wrong, but that's my sense of where Facebook is in the market.

I don't think Facebook will die, for two good reasons:

1) there are many more people on facebook than networks like myspace ever had. This makes a transition much, much harder.

2) facebook is not only used for facebook, but for many third-party apps as well. People will keep their facebook accounts so that they can log in to external services.

"TL;DR: Big social networks need to take advantage of the spotlight, and solidify their position to rely less on network effects. Otherwise, they are extremely risky investments."

Very good point.

drp4929 4 hours ago 0 replies      
Growing a company is one aspect while sustaining a company is another. Social Networks naturally take advantage of network effect while growing. It is not easy to sustain the company if perceived value provided by the company erodes quickly from its core customers' point of view. Whenever a company collapses usually it is because customers do not want its products for whatever reason.

I think MS will acquire FB.

The FB social network will die, in time, but it's still the world's largest email address list, plus all sorts of personal information that can be used to insidiously coax consumers.

Every FB user should gather up all the email addys of their friends and keep them in a safe place offline. This way you never lose contact.

FB allowed people to submit their email addresses to a central website and thereby connect/reconnect with friends, colleagues and so forth. This sharing of email addresses is not a new thing, but with FB it occurred on an unprecendented scale. Billions of email addresses (that work!). That is FB's contribution. Gather those email addresses and keep them offline. Soon you may be able to form your own social networks that are private, secure and more functional than FB. But you will need the email addresses of your friends to get it started. Don't believe that FB should be the safe keeper of your email address book. They will do what they have to in order to survive as their business winds down. Those email addresses are its most valuable asset.

Lyft's marketing has been pretty impressive to watch. Just this morning on my MUNI train I overheard a conversation where a guy was excitedly describing the service to another passenger, describing it as "way cheaper than uber". And the mustache branding is brilliant. Once I found out what it meant, I started seeing them everywhere. All around, a brilliant launch.

I love Lyft. Sidecar feels sketchy every time I use it and Uber just seems ridiculously expensive in comparison. John, Logan and the guys have done a great job to make it feel like a friend is picking you up rather than some guy with a car to drive you from point A to point B.

Lyft has a very bright future.
