> Google marked the bug as won’t fix because google chrome incognito mode is apparently not designed to protect you against other users on the same computer.

That's nonsense. For most users, that's exactly what it's used for.

I really think Google is dropping the ball here. I know it's not their bug, and they shouldn't have to work around it in an ideal world, but this is a pretty clear leak of data outside of private mode. It wouldn't impact performance in any noticeable way (you're closing the window anyway at this point), and would just be an extra safeguard.

Very short-sighted of them to ignore this bug. Perhaps we could ask distro maintainers to add patches for this to their builds of Chromium.
34th actually has usable T-Mobile connection.
They lose millions of dollars a quarter still. I don't see how Uber can dominate the market in the long run, when they'll have to raise prices to a profitable level and thus make it easier for competition to undercut them. Drivers can work with multiple services at the same time, and the barrier for consumers to install another app or navigate to a web app is pretty small.

edit:
If the regulatory environment doesn't clear up, though, I could see that making it easier for Uber to dominate the market. They have the wherewithal to challenge regulators in courts of law and public opinion, and to comply with whatever red-tape is imposed on them. New entrants would have a much harder time.
I am actually happy it doesn't drive without the driver.

Not that I have a Tesla, but I would never want to own a performance vehicle that drives without me. The whole point is to enjoy the experience.

They already took away engine noise and manual transmission.
Now might as well just have someone else drive you.
For SIMD types with elements other than Int8, in addition to the pshufb, there's also the cost of computing the pshufb byte indices.

For additional context, the current version of SIMD.js is aimed at covering the basics that strike some balance of being fast on most hardware and being useful. It's also just the beginning, and we expect it'll evolve to add many more features, quite likely including pshufb-like functionality.

Just one question, is it pronounced "risk five" or "risk vee?"
Both AMD and NVidia drivers have special code paths for different applications. I don't think it's anything sinister since these are mostly fixes for the game bugs and the rest are resolutions for API ambiguities.

To give an example, consider the difference between memcpy() and memmove(). On most systems memcpy() is as same as memmove() in the sense it works even when the source and destination overlap. Then you decide to optimize memcpy and to prevent bugs like this https://bugzilla.redhat.com/show_bug.cgi?id=638477 you will need to set a flag USE_MEMMOVE_INSTEAD_MEMCPY for every app that you know to memcpy between overlapped regions.
You could call this "cheating" or could be a reasonable person and say something like this https://bugzilla.redhat.com/show_bug.cgi?id=638477#c129 instead.

As for the original question. I am not an expert on the windows driver model but have written some GPU drivers and can tell that a) memory release is asynchronous i.e. you cannot reuse the memory until the GPU finishes using it and b) clearing graphics memory from CPU over the PCIe is slow and drivers, in general, do not program GPU on their own. Taking these into account, it seems the driver is not well positioned to do this and this is a task for the OS instead.
Self-driving trucks are also a thing
No they aren't internally RISC. On big Intel & AMD cores "ADD reg, mem" translates to a single uop. On Intel Atom even "ADD mem, reg" translates to a single uop. In fact, it is mostly legacy instructions (e.g. binary-coded decimal arithmetic) that are translated into multiple uops.
> they all have reasonable need of an introduction to abstract algebra.

Then the word "abstract" should appear in the title.
Musing about how it's not x APT because the code/attack is not "advanced enough" or "cheap" ignores plausible deniability.
The stock market isn't why there's so much VC money, it's because VC has better returns than elsewhere, and the stock market tanking only furthers that, doesn't it?

Aside from the Zero flag, there was also a Negative/Signed flag. Setting the high-bit in the last character (or clearing it if the rest had the high bit set) was also a way to terminate strings and save a byte over null-terminated strings.

People who go ape-shit over 0-terminated strings would probably be even more upset if we still did that.
How do you think this compares against http://basepair.io ?
I would suggest using this in conjunction with the scaled-up image technique in order to get the same blur effect cross-browser (see the posts elsewhere in the comments about bilinear vs. bicubic scaling)

Metrocard is going to be replaced in the not too distant future. I wouldn't be surprised if the next system has zones. They already have subsidized cards for low income travelers so a fare hike will have less impact. That's the only way they can begin to address their budget deficit issue.
Then you can go to work and send back the car to your significant other to take the kids to school and then send the car back to you when you need to come back home.
It looks like Safari uses bilinear as well.
I'd like international ACH/checking transfers to every country out there, mainly as a tool to pay international freelancers or similar self-employed people. I can say it's viable because I'd use it.

PayPal does this quite well, but they unfortunately mix this with accepting credit cards so they're subject to VISA and MasterCard's rules(hence all the cries of "PayPal shut us down and froze our accounts due to something triggering their chargeback risk alarm!").

Dwolla looks like what I want, but they're only in the US. Still, I'll probably use them to start with as an option.

What is WebAssembly? (2015)
After having 3 kids and going through a lot of strollers I can answer that a bit. A way to make a big improvement for yourself and for others is to buy the $50 basic stroller. Not the $500 "full-featured" one. Far better everywhere, and far more considerate of everybody else on pavement, public transport and everywhere else.

This: http://www.toysrus.com/graphics/product_images/pTRU1-3490966...

Not this: http://www.bobgear.com/uploads/products/stroller-strides-fit...

You'd think that a $500 stroller would be better, but after trying 3 of those it's just not true. A $50 one folds up to the size of large umbrella, and weighs 2-3 kg. A $500 one folds up to the size of a suitcase, weighs 20-30 kg. Even folded out they're smaller.

So it should be pretty obvious that a $50 one is far, far better anytime you have it with you and aren't using it as a stroller. Which is really quite often : in the car, on stairs, anywhere you're expected to sit down (from parties, at friend's houses, even cinemas). And truth be told, they're better when you're using them as well. They don't roll as nicely, but they're so much lighter. Also, you have zero issues with breaking them.
Just to vent: The 59th st connection that connects the 4/5/6 Upper East Side, Harlem, and Bronx to the heart of Midtown (N/R/Q) was down the other day at 8:40 AM on a weekday, after they had everyone standing on the track for 20 minutes wondering what was going on. Totally unacceptable.
Jython is still Python 2.7, so it's not an apples-to-apples comparison.
The Washington DC Metro has zone based fares that easily exceed $5 during rush periods and it's certainly done nothing for our quality of travel.
"Very little of the price of chips you buy is the material or packaging costs."

Are you sure about that? How much markup over material costs is there on most chips?
For the first time the expected value of a lotto ticket is greater than its cost
If they're releasing this to the public then the truth of the matter is that the technology is "there" for driverless parking but the regulatory bits are not. "There" in this case meaning the AI is less likely to get into an accident than a human.
It wouldn't be that much of a win using the feature as it currently stands. You could park them a bit closer together since you don't have to worry about getting the doors open, but that's it. A decent win, allowing maybe 20-30% denser packing, but not huge.
It funny what "merit" consists of from different perspectives. For google, merit may be to invert a binary tree. But most of the products by those googlers ain't that great.
As from my perspective, I think homebrew is something that deserves more credit(merit) than most of google's products.

The guy identified a problem and architectured a good solution for that problem. That already shows he has solid software development foundations, doesn't it? Even though he doesn't have a fancy degree.
Or, stated more positively, the government gives the poor subsidized loans so they can go university.

One of the troubles with 150mph performance vehicles is you spend 90% of your time going slow stuck behind traffic.
It would be interesting to know how the cost of allocating a new fbo would compare to the cost of zeroing it out. My guess is that the cost of getting into the kernel to do the allocation in the first place would dominate, but by how much would be something neat to measure.
Even if it did, so what? Nobody is forcing you to use these features. Don't like them? Don't activate them.
Socialize Uber
The MTA is not a business, it's a public service. We already generate enough revenue in taxes, but it's sent upstate instead of being used here. NYC subsidizes the rest of the state.

http://observer.com/2014/10/northern-exposure-the-give-and-t...
I want seats removed from the trains (456, L), so that people can actually fit.
The reason they're dancing around the performance figures is because a) synthetic benchmarks like SPEC and CoreMark are of questionable value, and b) They don't have chips in customers' hands quite yet, so they can't be independently reproduced.

If you look at the current results for Rocket and BOOM, you'll find that these microarchitectures seem competitive with Cortex A5/A8 and Cortex A15 respectively at comparable frequencies.

In addition to this, they seem to have some significant amount of space savings on die. Power/performance ratios already seem to be better (likely due in part to smaller die area).

On a power-performance front, a bigger OoO RISC-V could likely be competitive in peak performance to an intel, though you'd have to find a market for that. There has also been a lot of discussion about a real vector machine extension, and that would likely wipe the floor with x86's packed SIMD if done right.

They didn't compare papers at all, they compared proficiency at a well-defined and concrete task with an objective standard, and he was worse than a recent CS grad. But who decides a task is or is not a measure of merit?

And really, who decides a career social activist with good soft skills who can save the company 50 million in lawsuits and bad press has less merit than the engineer who may work for years on a project that ultimately gets canceled?
The oldest cars in the current NYC subway fleet are R32s built in 1964.
Well, can't argue with that.
Yes, they actually need to run the trains in that case so that the third rail doesn't ice up. They even stopped at all station stops, made announcements, and open and closed the doors. There was no reason not to just let people ride them.
also i was unable to find a reference to the version/build of java the author was using - thus negating any numbers/benchmarks presented.
You're right. There's enough diversity in SIMD instruction sets that no single rule seems sufficient for deciding what to include. Operations which are "fast" on all popular hardware are obviously great, but SIMD.js also includes some operations needed by popular use cases, such as allTrue() and anyTrue(). Also, while these operations are "fast" on x86 as you say, on NEON they're at least no worse than what applications would do otherwise.
CBTC and countdown clocks are orthogonal (although if you're doing CBTC, countdown clocks are a minor addition) - the A division has clocks, even though only the L is CBTC.
Because the human valet is effectively a common control system. To get all the cars to do this without humans they would need to be networked and agree some common communication standards. Cars aren't cellphones. The chances of a few hundred random vehicles, covering perhaps 20 different model years, all dancing together is a pipe dream.
Scanning the comments, it seems broken that there's no way for an end user to clear GPU memory. Particularly a way that works across platforms, or at least across drivers would be ideal.

If it can persist across restarts... does a shutdown do anything differently? I'm not too familiar with GPU programming, but there has to be something we can do.
I believe that in the markets they've been in the longest, they're profitable. It's expanding to more and more markets that makes them unprofitable on the whole.
calling attention to a story without upvotes or comments isn't very useful.
It shouldn't all be older, though - in the time that most of the Asian metros have been built, we've built, uh, the F train tunnel and a 7 train stop in the middle of nowhere? Really?
Thing about Baryshnikov was that he was so good, you didn't have to like ballet to be floored by his performances.

Some people don't like museums. I think that's largely because they haven't been to a great one, like the Met in New York or the Louvre. The second-raters (like everything in Los Angeles, for example, and I say this as a proud former Angeleno, actually are boring. Misha was like that in ballet.

I don't watch ballet anymore either, because I haven't seen anyone else like him in his prime.

Yeah, they're compound but don't have to be serial, due to the VPMIN/VPMAX instructions, but definitely much nicer on x86. For instance:

int all(uint32x4_t v) {
uint32x2_t x = vpmin_u32(vget_low_u32(v),
vget_high_u32(v));
uint32x2_t y = vpmin_u32(x, x);
return y[0] != 0;
}

(You can get away with a single UMINV/UMAXV on AArch64.)

It is very inefficient, if not anything else.
Packing tightly is efficient, but not always desirable. Sometimes you need a little more clearance in the rear for loading or unloading large cargo from the trunk or hatch. It's not going to work in a mall parking lot or a supermarket lot where you want to unload into the trunk from a shopping cart.
It's not just SSE2; SIMD.js also includes things like Int32x4.mul, which is a little tricky without SSE4.1's pmulld. It's kind of a balancing act between several concerns. Also, it's a base, and we definitely plan to iterate and add more features on top of it.

The ideal would be the car drops you off, parks itself somewhere nearby in a high density area, then returns itself for loading in an open area when you need it.
Many of the MTA trains are from the 70's too with classic simulated wood grain and all. Of course they do at least have AC.
I second this. This a phenomenal book. I didnt like it at first sight because I thought it looked kind of ugly, but the authors have a knack for clarifying some of the more arcane concepts in math in a very few words. It's not a cutesy bestseller that will end up teaching you jackshit, nor it's an intimidating monster like Lang's Algebra that's meant to put hair on your chest. This book is just right.
Even worse, huh?
In a few years, you will tell your smart fridge, "buy a car". The fridge will make the appropriate selection (a Volvo if you drink Organic milk etc.), make the payment from the appropriate account (keep the Swiss account for another day). In about 10 minutes, the car that now belongs to you drives itself to your home, while you go out for a walk.

I'm concerned that you seem to have made a clear distinction between good and evil when really there is none. Certainly we can apply our own society's general ideas, but it's not black and white in any way. Even murder is acceptable in many cultures. For example killing of soldiers during a war.

Excellent article. This one part stuck out to me:

> Youssef was dangerous, Callie stressed, and though Molly believed her—and the doctor determined that her head injury had not affected her recall—Ed and Sabi were skeptical. When Molly relayed the story to them in the ER waiting room, the two exchanged glances. It wasn’t possible. Callie had to be confused.

> ...

> Half an hour later, unable to fall asleep, Sabi heard the stairs creak, then a knock on her door. It was Youssef. He looked devastated. “My mother is dead,” he told her. “I’ve got to fly to Denmark.”

> Sabi stared, jangly with exhaustion and now fright. “Okay,” she said. A couple of hours later, Ed helped Youssef load his bags into a cab.

I don't quite know what to say about people like Sabi and Ed. I am reminded of https://en.wikipedia.org/wiki/Little_Eichmanns, but maybe this, admittedly overused quote, sums up my feelings better:

> In the End, we will remember not the words of our enemies, but the silence of our friends. -MLK

What poor human beings those two are.

Finally, Spoiler Alert!

> Then, just before the guards ushered him out, Youssef had twisted around, looked at her with his luminous brown eyes, and winked.

The mark of a monster. The article describes psychopathy in clinical terms but, especially in this case, I don't believe we should sophisticate evil. Yes, the concept of evil differs from time to time, culture to culture, but it seems too easy to make excuses for the depraved rather than to commit to decisive action to stop them.
Wow, and thanks for that. You are absolutely correct that Java exported all of the various integer sizes. Odd that I can clearly remember the debate and mis-remember the final outcome. Bill Joy was pretty adamant about "fixing" the various sizes of integers problem that C had been going through on x86 with the whole sizeof(int) != sizeof(ptr) code and we benchmarked it and it did not affect performance hardly at all. Wow it sucks getting old.

So why is JavaScript critical for this?

C, C++, Go, and pretty much every other language out there seeing use today is capable of working with JSON, making HTTP requests, and so on, in addition to supporting communication far beyond those technologies.

How are they any less capable than JavaScript in this case?
You can prove it through mathematical induction. Show that if it's valid for n dimensions then it's valid for n+1 dimensions. So then if it's proven for R_2 it's proven in general.
Can you elaborate on that? I find computer modern much more pleasant to read than Times.
Yes, that's exactly what they would do. If your car wasn't part of the 35% with that feature, you'd have to park in some other lot.
It's very easy to imagine this happening, mainly because the economic incentives line up for everyone involved. If you are a garage owner, you could create a "networked self-parking car only lot" - benefit for you is that you can park a lot more cars into the same space, benefit for the driver is they have more options to park, and benefit for the manufacturer is they can upsell you.

The self-parking car is the hard part. The algorithm to get a bunch of cars to move out of the way seems quite easy by comparison.

Yeah, Intel is one of the biggest companies in the world. I was just speculating an absolute floor for just the microcode in particular.
They're not random vehicles. The special lots would only be for the cars with this feature. If 100% of Teslas, BMW's, and Apple Cars supported it, you'd quickly see a bunch of other automakers get on board (Why not? If the car can already self-park, this isn't much harder from that point.)

At first, it would just be a few lots in the densest parts of cities. Within, I don't know, seven years, you'd be seeing them all over the place. Every shopping mall would have a special area for them, right near the entrance.

Oh, and don't forget: Cars of the near future (and Teslas today) can have features like this added years after leaving the factory, as an over-the-air software update.
