Was wondering about that. I'm surprised the OpenBSD team is accepting the commits - something so fundamental and Windows specific doesn't seem like their kind of thing - but great!

Best way to address POSIX compatibility concerns is implementing a proper POSIX layer in Windows (and not in a half-baked manner like the now deprecated SUA). I can't imagine how it would hurt anybody.

The UK is replacing roundabouts with traffic lights; US is doing the opposite theguardian.com

I don't see roundabouts as a replacement for traffic lights in the US. Above a certain traffic volume, you'll almost always want to move to traffic lights anyway. They're actually a replacement for the 4-way Stop - a ridiculous type of intersection that ought not to exist.

mixmastamyk 32 minutes ago 3 replies      
The question should be, what is best for this particular intersection in the near future? The two designs have different characteristics.

My understanding is that roundabouts are best when traffic is low, when it gets heavy they become much less efficient. Lights, while a lot of overhead in low traffic, scale better. There's also the question of space required.

Since the UK may have too many roundabouts due to traffic growth, and the US virtually none, they could both be building the opposite and making the right choice.

There seems to be no data supporting the article's assertion that roundabouts are being replaced by traffic lights across the UK as a whole. I'll add my own anecdata: many more roundabouts are being built in my area of the UK. There are also roundabouts with traffic lights.

As a driver, I much prefer roundabouts. When I'm cycling, I just prefer roads with fewer cars and can't wait for self-driving cars, since at least they won't be driven by idiots.

The headline makes it sound like it's a wholesale thing, but from how the article describes it, traffic agencies in both countries are discovering that some intersections are more useful, safer, etc if they had a different kind of traffic control. As information disperses, it becomes easier for engineers from different countries to share ideas and knowledge to figure out what the best course of action is for a certain type of intersection.

"Cyclists have a demonstrably harder time with roundabouts."

As the text acknowledges, a lot depends on the design of the roundabout. Just last week, we got https://bicycledutch.wordpress.com/2015/10/13/explaining-the..., which explains the current thinking of the dutch on roundabout design.

Also, roundabouts have become more popular, but traffic deaths certainly haven't gone up in the Netherlands (https://www.swov.nl/rapport/Factsheets/UK/FS_Road_fatalities...).

Wow I can't even. I live in Carmel, IN - basically the roundabout capital of USA. We just built our 100th roundabout and have several more near completion. Love them. Far better than traffic lights.

So weird to see the reason we have them is due to our Mayor visiting England many years ago. Now they are going the other way. Did their mayor or someone visit us and fell in love with traffic lights?

hugh4 34 minutes ago 1 reply      
It's possible they're both being sensible. Roundabouts are certainly under utilised in the US (unlike those awful four-way stop signs which are particularly hellish for law-abiding cyclists) so putting more in is a good move.

However, as traffic at any particular intersection increases it eventually may make sense to replace a roundabout with a traffic light. Roundabouts can handle large amounts of traffic, but only if they're large roundabouts -- if you can't expand the actual road space then the traffic light is the best move.

This is much better than the previous Go documentation, particularly in the concurrency area. The previous Go documentation introduced goroutines and channels, stated the mantra "share by communicating, not by sharing", and then gave examples with variables shared between goroutines.

It now seems to be recognized that, in Go, if you want to lock shared data, use the lock primitives. Don't try to construct locking primitives from channels; that's error-prone and hard to read. This new manual seems to recognize this. When they want a shared counter, they use a shared counter with traditional locks.

This is an interesting, if rather flawed, blog post. From what I can see, he says this (skip bullet points if you have read it):

- Mathiness is truthiness, but in the way that putting down any mathematical symbols lends an air of intelligence and truth to an argument, for many people, especially those who don't or can't take the time to understand the argument logic.

- Then he explains how economics data are not as easy to construct with universal agreement as with, say, physics (temperature). Agreement on practical action is hard when contrary frames and interpretations appear valid.

- He then mentions how this might be a problem for defining capital and other constructs for Piketty, but without any useful argument beyond this assertion.

- He then contrasts Feynman's integrity, trying to disprove his own work to make it better, to economist George Stigler's rhetorical style of conviction, ignoring contrary arguments, and playing the polemicist.

- He then mentions Isaiah Berlin's distinction between foxes who know little about something , and hedgehogs who know one big thing.

All these are interesting frames by which to compare and contrast various things. Yet his analysis, after bringing in all these ideas, is just to say that economics needs both careful analysis and effective rhetoric. Well, duh, but how does this tie into all the great setups he's made so far?

And mathy people are good at neither rhetoric nor polemic? But surely, if you're afraid of these people, they would be a mathy person who is using rhetoric to undermine the real philosophy and logic that should - pace Plato - be informing the argument.

It's a post full of story and setup, but as yet, signifying nothing.

Economics is genuinely harder. National income is a more complicated concept than temperature, and there are plausible alternative sets of rules for calculating it. Serious minded statisticians have spent many years discussing these issues, and there is now a UN-sponsored standardised system of national accounts.

But it is easy to write a mathematical symbol without giving thought to what observable fact in the real world corresponds to that symbol, or whether there is such an observable fact at all.

But isn't that exactly how we settled on the truth of temperature? Years of debate about what the right constructs for defining temperature mathematically are?

It's cool that they're tackling problems in the developing world, but it's nothing revolutionary. Evaporative cooling only works in places with low humidity, and their design requires low ground temperatures and a substantial amount of installed infrastructure.

It might be cheap enough and practical enough for locals to install themselves in the places where the low humidity and cooler ground temperatures would allow it to work. But if you put this device anywhere between say 35 degrees north and 35 degrees south it probably won't work very well because the average ground temperature will be too high.

FTA: A fraudulent chip can listen for that query and pre-empt the real chip with its own answer: a yes signal regardless of whatever random PIN the fraudster has entered. The attacker intercepts the PIN query and replies that its correct, whatever the code is,

Wait, what? How is that the protocol? There's no two way validation at all? The chip just says "yes"?!

Can anyone with knowledge of details confirm? This seems isomorphic to my ears with "the PIN is just security theater".

JimmaDaRustla 2 hours ago 2 replies      
This is technically old news - as the article states, it has since been resolved. Edit: I guess they're shedding new light on how they performed the hack.

Another thing, in context of USA, is that the authentication being done isn't much of a vulnerability as this only applies to offline chip transactions. In the USA (I believe) and here in Canada, all transactions are online, which means the pin will be rejected by your financial institute's back end systems in these scenarios.

These types of hacks have since been corrected using what is called CDA (Combined Data Authentication). Blurb on SDA/DDA/CDA here: http://www.cryptomathic.com/hubfs/docs/cryptomathic_white_pa...

Edit: Many Canadian financial institutes still use the weakest data authentication (SDA) because all transactions go online - spoofing a card PIN verification response doesn't fool the back-end system. Visa and Mastercard both have mandates to have newly issued cards be provisioned on chips with CDA (I believe, could be DDA which would still be susceptible to this attack).

Edit 2: When I say "offline", I mean at a point of sale machine - the POS does not reach out to the payment network to perform an "online" transaction where the PIN and card are validated by the back-end systems.

Edit 3: The article doesn't give EMVCo any credit for actually solving the issue before any real world hack was known to exist.

That's amazing. They were able to MITM the chip-and-pin chip by taking it out and attaching it to another hobbyist chip that's capable of spoofing the response, and the whole thing when put back in the card was only a slight bulge bigger than the original.

They say nearly 600k Euros were charged, but given the sophistication of the attack, I wouldn't be surprised if we hear later that it was in use at different locations as well, and we just aren't hearing about it because they haven't caught those people yet. They only caught these ones because they kept going back to the same locations.

I was under the impression that the card created a cryptographic signature on the transaction, and the card had to receive the correct pin before it would sign it. Which is why you have to leave the card in the reader until the total is completed. Is this really not the case? Or does the card still cryptographically sign the transaction, but doesn't process the PIN first (other than answering valid/invalid)?

The more famous an analyst is, the more likely he is to be confident in his abilities, and the less likely to second-guess himself, to analyze his analysis. Those analysts who must defend their work to superiors do a better job.

The same thing seems to happen in other lines of work - when an engineer is accountable to code review, he might do better. When an author is subject to the will of an editor, his work is ultimately achieved faster, and with better quality; witness George RR Martin's speed on the first three books in A Song of Ice and Fire versus the glacial pace of the last two.

That would give you more fan area than you can get with a geared turbofan, optimal fan speed for efficiency, redundancy in case one of the fans suffered damage, allow cross-routing of power between turbines if one turbine failed, and not require quite such large fans so they'd fit under the wings more easily.

Propecia was "designed" as a prostate drug, but didn't do so well ... but mystery unexpected side effect! Kind-of-sort-of baldness cure! So yeah, that's what that drug is for.

Nilotinib was "designed" as a leukemia treatment, but ... didn't go so well.[1] Oops, just kidding - it's a parkinsons/dementia treatment!

(also, one of the erectile dysfunction drugs, I forget which one, was also "designed" for something similarly unrelated...)

The real headline here is that these people have no fucking idea what they are doing. They are throwing shit at the wall to see what sticks and then informing the marketing department as to which side effects were the most interesting.

This dovetails nicely with their other favorite activity: finding efficacious natural compounds and then tweaking them just enough into a synthetic compound that can be patented.

Just look at the millions of dollars pot alone creates in tax revenue.

In a decade we will look back and think "how could we be so stupid for decades".

And I'm looking forward when "harder" drugs like cocaine, meth and heroin are legalized or at least tolerated - no more drug turf wars, no more shadow states in Latin America, and especially far fewer deaths and medical issues from contaminated drugs.

Drugs are actually pretty safe, what makes them so incredibly dangerous is the contamination happening in the supply chain, from unclean manufacturing over normal degradation due to improper handling to stretching at the dealer level.

Also, Prohibition was enacted via a constitutional amendment, yet a large portion of people simply ignored it. It always gets understated what a massive crisis this ended up being for the integrity of the US Constitution. If one amendment was seen as optional by an increasingly larger group of people, maybe the others would be as well. It was important for the integrity of the government that they repeal the amendment. I have a feeling if prohibition were enacted via a complicated loophole like the one that keeps the horrible 21 drinking age afloat it would have been much harder to repeal in full.

I can't really tell what they're trying to say here.

The repression involved in the implementation of alcohol prohibition had an effect of pushing a common and integral part of society into the black market.

The NRA is promoting the right to bear arms, and actually it would seem that the effect they're seeking should be the exact opposite.

Effectively, as prohibition pushed a polite leisure into the black market. The NRA's goal appears to be the exact opposite: that is, to keep a polite leisure out of the black market.

I don't think German understands the irony of this, because I get the impression that they want to compare the moral status of the prohibition movement to the moral status of the NRA.

I paid for my first PowerBook G4 this way. I didn't buy the built-in SuperDrive because I knew I'd burn it out in a few months, so I got a Sony FireWire DVD writer.

I had my PC setup with all the file sharing programs, hammering my cable modem 24/7, downloading movies and music. DVD's were $10 and audio CD's were $5.

My main competition was bootleg movies on regular CD's that you could buy at flea markets, gas stations and party store but they had terrible quality. Not just because they had to fit on a CD but many of them were shot in the theater with a handheld video camera, not rips from IRC channels. They were only $5, though.

It was way too much work driving around dropping discs off and I couldn't use my laptop for learning Cocoa, so I stopped doing it after a few months.

Looks cool, but I don't know anything about this market so I can't really comment directly on utility or prospects. But, to take a tangent:

I think there's a shift that hardware oriented entrepreneurs might mine for some ideas.

Around web 2.0 time there was a shift where people got more comfortable with the internet. They used real names, and pictures without expecting this would inevitably lead to serial killers at the door. Facebook worked because people agreed to tell the internet their name. Online dating went mainstream. Twitter, Linkedin, all sorts of sharing become common. The interesting part is that the technological trends like were only part of the picture. Cultural shifts were just as important.

Tech is cool now, that's the new trend. Where a calculator watch in the 90s would get an 8 year old beat up, todays equivalents are status symbols. Interestingly, glasses became cool in recent years.

So, ideas might be found by looking over old technology that is uncool and seeing if it can be re-imagined as 2015 tech. A regular electric wheelchair is uncool. This segway thing is cool.

One real obvious device to think about Apple-ising is hearing aides. Hearing aids are so uncool 80 year olds don't want to be seen with one. They are all about being small, flesh colored and "invisible." I think there's a decent chance a bright green large ear piece might be cool.

And speaking of hearing aids Can hearing aids improve the hearing of non impaired people. Can you get better than normal hearing from a hearing aid?

I for one think it's a good thing Heroku is not joining the herd in a race to the bottom.

$7 dollars a month to run a little app? That's less than I spend on coffee each day and I'm glad that money is going towards differentiated and valuable service.

I have a couple of toy apps, a personal blog and a "not such a toy" app on Heroku and I have used their services for free for AGES - more than fair enough that they make some money.

There's one cool alternative I found: Hetzner Online[1] leases dedicated hardware that their other customers stopped using or ordered but didn't use, etc. It is in form of reverse auction - unused hardware gets cheaper until someone rents it.

You can get i7-3770 server with 2x3 TB disks and 16 GB RAM for 32 EUR per month. That's not much more money than linode, but it is much beefier and just your (but no SSD). If you pay more you can get something like i7-3770 with 32 GB RAM, 2x3 TB disks and 2x240 GB SSD for 65 EUR a month.

The servers are in Germany, which might be interesting for Europeans who are wary of US cloud companies.

A reasonable option for hobbyists is Dokku[1], a single-server heroku clone. I'm also pretty excited about Convox[2], and would definitely recommend that early adopters check it out.

I get that people are frustrated with heroku's pricing, but at the end of the day I think that if your side project isn't worth the money you spend on it's hosting, maybe you should look into other side projects? If it's truly not a money-making project, not needing to scale it or have it up 24/7 seems like a reasonable trade-off to not paying for it's hosting.

The number of tools and resources Heroku provides is quite significant, and developing/deploying/maintaining similar solutions is certainly not cheap or easy. Especially at scale.

I can certainly see the point where Heroku comes out wildly overpriced for certain types of hobby-scale apps. I've seen several people recommend dedicated servers via Linode or DigitalOcean instead, which has it's own pluses and minuses - gotta maintain the server, but for a pretty low price, you get something powerful enough to run a 24/7 server + database + whatever other odds and ends your app needs, as long as the demands aren't too high.

I'm wondering how AWS compares, though - running a dedicated, manually managed EC2 instance or ElasticBeanstalk. Seems like you could get your own server, and still have little barrier to scaling as high as anybody could ever need at the touch of a button. Anybody have much insight on that?

Regarding the fifth point on SSL, I agree, but I'd recommend investigating a combined Heroku and Cloudflare stack as I've described here:

https://brandur.org/fragments/cloudflare-ssl

You can stay on the free tier of Cloudflare and the hobby tier of Heroku and get full encryption on your custom domain (and without worrying about getting certs issued). This is how I run my more important hobby apps.

And regarding the lack of novelty of `git push heroku master` I'd argue that it's still surprisingly valuable even in modern times. Sure you can do it yourself using a dozen different techniques these days, but as a hobbyist I want to be building apps and not maintaining personal infrastructure.

(Disclaimer: I used to work at Heroku.)

While my instinctive reaction to Heroku's shift was "ugh, that sucks, how dare they," I have to say I get it. It is hard to build a successful business with that model given their offering.

However to the comment about "git push heroku master," someone that is an "early" programmer like myself finds that level of simplification helpful when I'm focusing on things like learning all the other things that could go wrong with my Rails Tutorial app.

That said, as I now am at the point of starting to work on projects that I hope to one day be public facing, I'm wondering if there are any recommendations for "Heroku-like" providers with a free tier that stays up 24/7 for super simple Rails and Sinatra apps, perhaps with a DB.

I think it's still pretty friendly to hobbyists (throw up a quick Flask app for a demo, etc), but it's probably no longer very friendly to 'get everything for free'ists (like 24/7 compute, >512MB ram, etc).

The benefit to me of using something like Heroku is not because I get more CPU/RAM than an equivalently priced Linode instance - the value is in not having to manage a Linode instance at all.

I'd also argue that git-pushing to Heroku is still a lot less friction than dealing with docker images or chef/puppet scripts.

rubyn00bie 40 minutes ago 1 reply      
Not to be rude, but these complaints, minus the "increase" are standard Heroku practice. I see no changes-- in fact, what has changed there, anything?

They're finally too expensive for you, or you outgrew them? They aren't cheap, and never have been, especially for hobbyists.

If you have a hobby, you most likely have more time than money to complete your hobby, so why, why use something like Heroku? The very nature of your activity is to spend your time, not your money, Heroku is only giving you the feeling of savings until you outgrow their nearly worthless free offering. Now you have to spend your time, moving, configuring, and learning an "entirely new" system. Had you done this the first time, you'd have saved money/time.

Yeah... "git push" to deploy is easy[1]-- and if you're new to application development it can be nice, but! It also means you have no idea how to configure or run your app (i.e. deploy). It means you're more vulnerable to your vendors quarterly earnings needs (price hikes), it means you're more vulnerable to vendor technology changes (lock-in), it also means if it ever hits the fan-- you're gonna have oodles of downtime while you learn how to do it "right" the first (nth) time.

FWIW, it's actually really easy to run a VPS that's stable once you learn how to do it properly. Don't fear it, mate. I've always found it nice since none of my projects ever get substantial traffic, I can usually run some auxiliary service I need (like Gitlab) on it too. A two for one, eh?

... One last thing, if you're running a business Heroku might be the right choice (it's up to you to evaluate the risk/reward).

[1] I personally think deploying with Capistrano is a cinch (cap deploy) but it'll take you a lil' bit of effort to set up the first time.

You know, you could probably build a whole new shell around this whole concept. Solve a couple of the fundamental UI issues (i.e., I don't really want my insertion point or the text I'm editing to be bouncing around as things chunk in) and I wouldn't be surprised you could take this concept further than you might initially think. For instance, one issue I often find I have is stale information as I flip around my shells; if my source plugin was updating in realtime everywhere, that would be useful. And I mean that as just one example of the sort of thing that could be useful if this was taken in deep in a new shell.

One thing that would be nice would be to put the output of shell commands into a separate column from the prompt, with an ability to collapse or expand the output, outliner style. Modern computer displays have lots of extra real estate, theres no reason to require everything to fit into a window 60 or 80 characters wide.

you could also just type '&' at the end of each command ;-)

What i'd like instead, is based on the same issue/idea, which would be a real "linemode" where your prompt is "locally updated" and anything sent to "the shell" is asynchronous.

This would not fork processes in the background (i want to be able to be selective on that obviously! so it would queue up processes if i dont specify '&' for example) but ensure that you can always get back to the prompt.

This also makes it so that the prompt would be instant over the network as well.

Note that some protocols do support linemode, just not SSH, or obviously not the native common shells either, at least, not without building a forked version

I've been working on open-source balloon control software [1] for my own balloon project that I've been building on/off for about six years. I am hoping to use a software modem to bridge between the RF and my AX.25 packet reader/writer [2] because I wanted to save weight. Payload weight is the name of the game in the balloon hobby--the lighter your payload, the less you have to inflate your balloon and the higher it will fly before it bursts. Even an ounce matters and the competitive altitude record balloons are invariably tiny, single-board, all-in-one payloads that are built around a single low-power microcontroller.

There are a couple of good open source options for software-based AFSK APRS modem/TNCs:

Dire Wolf: https://github.com/wb2osz/direwolfminimodem: https://github.com/kamalmostafa/minimodem

You'll still need a USB sound card though, which adds weight and cabling. I would love to see some open-source SBC hardware a la Beaglebone Black or RasPi that had a high-quality sound card built onto the board and wired through a Molex-type plug that was suitable to the bumps and bounces of flying.

It's nice living in 2015 when you can code your modem in Octave, an interpreted numerical computation language, and not put an appreciable dent in your available CPU.

He approaches the problem at a higher level than a typical modem, for instance, he uses predictable data in the packets as framing instead of the deficient framing provided by the bit level protocol. When confronted with a corrupted packet he also tries to guess the true content by doing a "what if" analysis on the marginal bits to see if flipping them the other way fixes it.

Hey all, I'm the founder of SourceDNA and happy to answer any questions about how we found this or about binary code search in general.

We take a different approach to understanding code than the traditional antivirus world. Rather than try to hunt for a needle in a haystack, we've created a system for finding anomalies in code that's already published. For example, you can build a set of signatures for "bad apps" and then repeatedly search for them (AV model) or you can profile what makes an app "good" and then look for clusters of apps that deviate from it (SourceDNA).

Consider an ad SDK like Youmi here. They weren't always scraping this private data from your phone. There are some apps that have this library but that version is a typical, only sorta intrusive, ad network.

But, over time, they began adding in these private API calls and obfuscating them. This change sticks out when you track the history of this code and compare to other libraries. There was more and more usage of dlopen/dlsym with string prep functions beforehand. This is quite different from other libraries, where they stick to more common syscalls.

By looking for anomalies, we can be alerted to new trends, whatever the underlying cause. Then we dig into the code to try to figure out what it means, which is still often the hardest part. Still, being able to test our ideas against this huge collection of indexed apps makes it much easier to figure out what's really going on.

I'm actually very surprised this hasn't happened years ago. The power of Objective-C's runtime has always made this pretty straightforward.

Apple can defend against unauthorized calls to even runtime-composed method names though. I can think of a few ways.

They could move as much "private" functionality as possible outside of Objective-C objects entirely, which requires that you know the C function name and makes it obvious when you've linked to it. This should probably be done for at least the really big things like obtaining a device ID or listing processes.

Even if they stick with Objective-C, they could have an obfuscation process internal to Apple that generates names for private methods. Their own developers could use something stable and sane to refer to the methods but each minor iOS update could aggressively change the names. If the methods are regularly breaking with each release and they're much harder to find in the first place, that may be a sufficient deterrent to other developers.

They could make it so that the methods are not even callable outside of certain framework binaries, or they could examine the call stack to require certain parent APIs. At least that way, if you want to call a private API, you have to somehow trick a public API into doing it for you.

And, I think Apple does say somewhere that developers shouldn't use leading underscores for their own APIs. They could hack NSSelectorFromString(), etc. to refuse to return selectors that match certain Apple-reserved patterns in all circumstances.

Seems like a lot of the things they're putting behind private APIs should instead/also be behind a user permission. Getting the list of installed apps, device serial number, and the users email address shouldn't be protected simply with obfuscation.

I'm not an iOS developer (well, not really; I don't know what I'm doing) but this seems like it would be a really easy thing for Apple to detect. Does Apple simply not care about access to these to the degree of adding in better checking or is there something fundamental about their platform that makes checking for Apple seriously difficult?

> Since we also identify SDKs by their binary signatures, we noticed that these functions were all part of a common codebase, the Youmi advertising SDK from China.

Know your binaries?

"The apps using Youmis SDK have been removed from the App Store and any new apps submitted to the App Store using this SDK will be rejected." I'll be interested to see what happens to Youmi now that they're blocked from iOS.SDK developers: Consider yourselves warned.

This is not new. Check out "Microsoft AARD code" -- an inverted example of surreptitious analytics, in 1992. TL;DR: the beta version of Windows 3.1 showed a warning if user was using DR-DOS, a competing OS. The payload was encrypted and could be triggered in the production version of Win 3.1 by changing a flag.

Very nice! I looked at them from several perspectives, and saw some neat things. I like that you have curated commentary on each item, and included (I think) referrer links to Amazon. I was pleasantly surprised to be asked if I wanted to be reminded about something -- not sure what triggered that, but it was cool. I'm going to try using this for my amazon wishlist-creation. ;)

It looks very nice. Would you be willing to write about the tech stack you used for this?
