I think this is some kind of psychological projection/rationalization because the statement "Having been well and truly spoiled by illumos threading (and especially illumos kernel threads)" is actually quite laughable.
RFC 7858: DNS over TLS (2016)
The bashing is truly amazing. Not only does it lack constructiveness (in most cases), but Gnome (I speak of Gnome here not to the exclusion of KDE. I just happen to be a Gnome user) is beautiful, and has been for years.

Thank you Gnome team, including designers, that created such a beautiful desktop experience for me.
Do they actually have GPS?
The Chinese bikes have a dirt cheap BLE module; the App pulls GPS data from your phone.

Which is to say, when people displace the bikes "manually", the maps are no longer accurate.
New iOS Update Kills Touch Functionality on Repaired iPhone 8s
Nicely ask in the bug tracker about how a designer can help. Maybe start with a mock of what you want to change. I'm sure most open source developers will put in extra effort to help you because they value contributions from designers.
Sure, slavery was outlawed 150 years ago, after several centuries of practicing it, but after it ended, there was a separate regime of laws and extralegal terror that made it hard for former slaves to build wealth. There's a direct line to today, where most middle class families got a big chunk of their wealth from home ownership, which was explicitly racially segregated (not just the housing itself, but the loans). Now, is this technically "slavery"? No, but it comes from that past. Of course, millions of immigrants and descendants of former slaves have achieved economic "success", but it seems pretty clear to me that the shadow of slavery still shapes our economy in important ways. You may disagree, but calling it a "lie" seems a bit much.

This is nonsense. NT kernel happily creates thousands of threads. Just made a little test app to try. No issues at all.

Inconceivable! I'm convinced this person worked for aliens in human skin suits. Think Edgar from Men in Black. Obviously missed the memo from high command where it is mentioned that humans perform better when caffeinated so supply them with plenty of free coffee and tea to keep them productive and ready to harvest, er, review.
Nowadays, in some circles, the word technology has been redefined to mean "websites". And maaaaybe other software, but that's borderline.

So electronics, rockets, robots, lasers, medicine, skyscrapers etc. etc. are no longer considered technology.

Sounds like what people said about Segway. Don't remember if it was Jobs, but somebody of approximately his tech reputation said "this will change the way we build cities."
Exactly. It drives me nuts in startup world the "push for MVP" or critical path first -> release -> iterate/improve, yet when the product gets released it is criticized for rough edges, bugs, but most appallingly missing features.

Gates don't have to be Hermitian right? Like NOT^(1/2) is not Hermitian.
Iter-frame parallelizability is made possible (at least in the context of h264) by using slices. It comes with a minor penalty in the resulting data compression ratio.

I don't understand biking in Chicago or Minneapolis. What do you do when it rains, or snows, which is like 2/3 of the year? And after that it's 95 degrees and 98% humidity. There are probably no more than 30 to 45 days a year where it's really decent biking weather.

It was already in wide use long before then. Microsoft's MFC was first released in 1992, and that was the Windows desktop library for years.

Actually, our modern food system isn't working for the hundreds of millions of us who are dying from obesity, heart disease, cancer, diabetes, etc. Nor is it working for those of us (all of us) who are presently going bankrupt trying to pay for each other's healthcare.
iPhones are secure, maybe they contain backdoors from Apple and we don't know, but Android are not secure at all, especially because most Android vendors usually don't update the OS to the latest security patches, so the majority of the Android phones out there are full of unpatched security vulnerabilities.

Also there are not good free software mobile operating systems, sure there is LineageOS and other ROMs that still require some proprietary parts, mainly the firmware of the device and binary blobs in the kernel, for one person concerned about privacy that is a problem, because proprietary software means backdoors, and it's useless to use a fantastic free software secure communication app if we can't trust the OS where we run it.
To be honest, there were about 10 bikes within 400 feet of where I was. There just wasn't one exactly at the restaurant. I would have had to walk probably 2-5 mins to get another bike. That 2-5 mins is probably still better than where a dock would have been. It's really weird being out there because it seems like there are bikes everywhere in Tempe.

Yes too literally.

We introduced a welfare state that for all its many failings, gave those at the bottom of society a floor below which they could not fall below, and that was a floor that gave sufficient supprt to grow and flourish.

And with that flourishing came new talent, talent that had been previously held back by circumstance, and that talent helped drag the bankrupt UK out of its own collapse and bankruptcy (post WWII)

The UK (and Europe) no longer have that vast inequality and underclass, but like its shale oil reserves, the US has cunningly kept tens of millions of poor and downtrodden citizens in misery, just so you can turn on the gas and surprise the Chinese economy with one last blast ;-)
Unfortunately there's an ordinance in my city saying you can't use an ebike without a helmet or something so the bike shares here aren't touching ebikes yet.
My usual profile for those bikes is tourists and young professionals. These were grizzled, grubby older men. Plus, the theory of these bikes is as last-mile transportation; I've never seen them on BART before or since.
Are you assuming no one ever finds zero-day vulnerabilities in "trusted" code? What happens when a piece of code that you trust is compromised in a way you didn't expect?
I've been trying to build my own mental model that's easy to visualize how your eyes build color.

Imagine 3 people (r,g,b) standing across from each other playing a 3 way tug of war with a bowling ball in the center. They each can feed on certain ranges of radiation to help them pull the ball towards them, color is determined by where the ball ends up. If red and green pull equally the ball moves sideways out of the center to land on yellow.

Now take it one step further. The ball actually starts out in a deep pit, if everyones only pulling a little bit the ball lifts up but stays in the center, you have dark grey, if everyones pulling at their max, you get white. What seemed like a flat plane tug of war is actually a 3 dimensional cone.

Now take it one step further. The retina is typically composed of 95% red and green cells of various mixtures, and only 5% blue. That means the blue person has a very short rope to work with compared to the others and is not able to move the bowling ball into as many unique positions as the others.

If you are red green colorblind then you only have 2 people playing tug of war. Your color model is now 2 dimensional. If you have tetrachromacy you have another person playing and capable of placing the bowling ball into positions not possible with just 3 people. Additionally there is no such thing as pure green, because all radiation that green feeds on will also feed either red or blue as well.

edit/ I forgot to add the rod cells, they are another "one step further". They are one extra person but they stand directly over the bowling ball, only capable of pulling upwards, but they are very weak and can't lift it very high.
It doesn't really matter even if there are, in the case of hardware implementations -- because hardware decoders/encoders are typically fixed-function hardware blocks with fixed functionality. They are not designed for flexibility or reuse between formats. They are designed for exactly 1 function and nothing else.

Even if AV1 and VP9 share structurally similar components, no VP9 decoder is going to work out of the box. It may mean that people who produce AV1-capable encoding/decoding hardware have a better starting point, though (provided they had VP9 hardware, beforehand)

From the article:

> nanomsg has dozens of state machines, many of which feed into others, such that tracking flow through the state machines is incredibly painful.

> Worse, these state machines are designed to be run from a single worker thread.

Despite the negative tone, the author gives me the impression that nanomsg as a simple, consistent architecture that just needs to be documented better or perhaps refactored.

State machines are useful for precisely the reasons the author states: their behavior and performance are easy to reason about and state machines can enable concurrent processing of multiple tasks when when you're limited to a single execution thread.

The simplicity of state machines makes them useful for secure code or embedded processes where debug visibility can be poor. Embedded environments like microprocessors also benefit from the single-thread concurrency, but this can also be handy on more capable OSs if you want to cut the latency of fork() or pthread_create().

State machines are a really useful tool; there are worse complaints you could make about a code base.

HiDPI on Linux is only broken if you need fractional scaling, or different per-monitor scaling factors. If you stick to screens that work well at 200% (e.g. 4K on 24"), then current desktops will work just fine in my experience.

That sounds like a draconian restriction if you are coming from Windows 10, but OP is switching from macOS. Macs have traditionally used either 100% or 200% as well (except for the latest-gen MBP).
Agreed on the difficulty: you would aim first at the low hanging fruit for placing the taps, the easiest being the onshoring spots.

But... for the MEMS, I consider this as one way only (public, probably crude/basic) and very possibly we'll learn of other techniques that are usable in say, 5, 10 or 20 years. That's what our taxes are financing in the end ;-) research on fundamental new ways to tap the neighbour/hostile country's fiber.

Lastly, I wouldn't sweat it too much on data/speed capacity but more on power needed to process and Y-split this datafeed to exfil. If in the future we got to learn that micro/nano-nuclear powerstations were tied to submarine interception points, I wouldn't be surprised at all.

The data/speed capacity is probably the less difficult part compared to seamless insertion, power and exfil system.

Now all these are just guesses based on what's public so far thanks to Snowden & al.
Who's promoting it? People should be free to choose to do what they want with their own bodies. That seems like a pretty basic moral principle. The burden of proof is on anyone looking to contravene that.

Rule of thumb is often an average 10% growth for index fund return (e.g. S&P 500) - this would be over many decades. If you can't put in 10%, at least put in up to what an employer matches - unless you are very low income, it's worth it and once it's sequestered from your day to day budget you won't feel the difference of 1-5%.
Based on earlier discussions, I thought it was really hard to see a satellite if you don't know the orbit.

I did some calculations, and a 15m object (largest that fits in falcon 9) at 300km (lowest orbit) has an angular diameter of 0.006 degrees.
That amounts to taking up about 0.000005% of the sky above the horizon.

I figured the required resolution to cover the sky well enough to see that would be ridiculous, but 20 megapixels spread over the entire sky would then be enough that this satellite could occlude an entire pixel.

Considering how many hobbyists there are, this does indeed seem feasible.
Facebook Launches New Initiative to Help Scholars Assess Impact on Elections
To expand on what merinowool said: Under capitalism you are free to do whatever you want with your own property provided you extend the same courtesy to others, and don't interfere either their use of their property. It is easy to see that this is an optimum balance: any more freedom than that would necessarily come at someone else's expense. This is sufficient on its own to say that any other system must be less free than capitalism.

"Democracy" comes in many forms. If a particular implementation of democracy includes strong (effectively absolute) protection for the rights of the minority, including property rights, then it becomes a special case of capitalism where interested people voluntarily choose to address issues of common concern through voting. One example of such a system is a co-op; no one is forced to participate, but those who do become members have equal representation with respect to the disposition of the co-op's common property.

If respect for the minority's rights is subject to majority vote, however, then things which one would be free to do under capitalism—by definition involving only one's own property and that of others who voluntarily choose to participate—become restricted to suit the will of the majority, which plainly makes one less free.
I've been cycling in SF for more than a decade and am a SF Bike Coalition member, so I doubt I'm underestimating it all that much.

But even if you are right I don't understand why Uber is eager to buy in now. If this takes off so much that Uber is obliged to get in on the action, they can wait. It strikes me as like Apple with MP3 players or smartphones or smartwatches: it's cheaper and easier to let somebody else prove the market and then just come in and crush everybody.
Their original location was a little ways across the Lawrence Expressway from the original Fry's, which was near the original Computer Literacy Bookstore, which was in the same small shopping center as a Togo's.

Dude, all offers are greater than the minimum. Doesn't make sense to offer otherwise.
Yeah, this is to some extent a matter of how you define "self taught". I believe that learning to write code does require reading and analytical skills at a level typically found in a college graduate. If you've had many years of formal education developing these skills, but didn't take courses that involved formal coding... I'd say it's stretching things to act like you're entirely self taught.

Suppose you go to college and double major in philosophy and pure mathematics, but never write a line of code. Then you get a job and start reading and coding extensively on your own, until you get good at it.

To me, it blurs the line somewhat to call a person like that "self taught". There's a lot of ambiguity, and I'm not entirely sure what the term means, at that point. I mean, everyone has to learn something they weren't taught in school on the job.
Twitch is just one example, and I'd assume most live video viewed would benefit from a lower delay. That goes for everything from security cameras to sports to video chat. I'd bet that for the vast majority of live video a lower delay would not be a "liability", but rather a plus.
What a dag.

well, in the UK a hundred years ago our cities hid poverty of the kind that is rare in modern world (war zones and the like). Rowntrees reports were transformative in understanding of same - https://en.m.wikipedia.org/wiki/Poverty,_A_Study_of_Town_Lif...

Also it's worth noting that modern notions of poverty are relative - with the "poverty line" often being drawn as some % of median income.

Of course this is discussing inequality of wealth - which is what we usually mean, and is the pillar around which the other inequalities get talked about (unequal opportunity due to race, religion, education gender etc)
It really depends on degrees. I've seen apps that were so bad, I couldn't even figure out what to do. It could be mathematically provable under the hood, but if I can't even figure out how to use it, or if the experience is bad enough, I won't care how well it is implemented.
> We asked MIT whether we could incorporate Kerberos (and other encryption) into the X Window System. According to the advice at the time (and MIT’s lawyers were expert in export control, and later involved in PGP), if we had even incorporated strong crypto for authentication into our sources, this would have put the distribution under export control, and that that would have defeated X’s easy distribution.

Fascinating.

Oh wow, am I wrong? I thought all quantum operators were their own inverses, which since they're all unitary means they must be hermitian.
>these matrices must be their own inverse (in mathematical terms, Unitary and Hermitian)

Not necessarily. The only requirement on quantum operators is that they must be unitary. Only observables have to be Hermitian (so they have real eigenvalues).
I have a similar story. My current girlfriend was living in another city about three hours away, I never would have seen her profile in my possible "matches" because I wasn't looking in that city. She did a search query for an author we both like, and my profile came up. If she didn't "visit" my profile and pique my interest I likely never would've met her! I'm sad to think that with the changes OKC have made recently (haven't used it since I met my GF obviously) people will have less luck finding people. They want to turn it into a Tinder clone.
