My loved ones are out of town, so you're on! I'll do it for the fun of it and the experience. And because I still haven't built anything on top of kafka, but there's no time like now to fix that.

The challenge is: Meet the main requirements of r/place: 1000x1000 image, a web based editor, 333+ edits / second, with an architecture that can scale to 100k simultaneous users (although that part will be hard to actually test). I won't implement mobile support or notifications, and I won't implement any sort of user access control (thats out of scope). The challenge is to do it & get it hosted online before I go to bed on Saturday (so, I'm allowing myself some slop there). But its already 1:30pm on Friday, so I think that easily qualifies as "less than a weekend".

As a stretch I'm going to write all the actual code in nodejs while aiming for well into the thousands / tens of thousands of writes per second territory.

I'm willing to accept some fun stakes if anyone wants to propose them (ice bucket challenge level stuff). I'll live-tweet progress here - https://twitter.com/josephgentle

Can someone explain the significance of this post?
I love my vive and all, but having to deal with it for every meeting just sounds like a hassle.
Credit card employees aren't verifying anything. All of my credit cards have been opened remotely: online, and through the mail.

And I can count on one hand the time a merchant has actually checked my signature against the credit card. And for charges under $50, most places don't even ask for a signature.

Best to just get rid of the signature entirely and speed up the transaction. It's pointless.

That varies a lot by language. I keep finding its attempts at Polish painfully bad, and I only know a little Polish myself.
It emulates the NES perfectly, since it exactly emulates the NES hardware on more powerful modern hardware. Every glitch will work exactly as it does on an actual NES. That was their goal. A few places have reviewed it to ensure the glitches work as expected -- sure enough, they do.

They had some of the most hardcore folks in the emulation community included in the development. The guys who designed it wanted it to be reference quality. It supports all the options of every NES made, including full support for custom sound chips (like FDS versions of Castlevania 3, which sound amazing), and stuff like the PowerPak and Everdrive -- because to the game, it IS the NES.

It's exactly why I'm getting one myself. As a speedrunner, reference quality (whether on hardware or software) is a requirement for me to have my world records be considered legit.
I would agree. Basically all decent build systems will allow you to compile units that aren't dependent on each other in parallel. Threading the compiler may provide some gains, but it's likely that for a good portion of your build time your CPU is already fully utilized anyway (And without any locking overhead).

I feel like the real gains would be with a threaded linker instead, but I can't say I have any data to back that up. But I mean, you can't link until everything is compiled, so presumably there are free CPU cores that could be used.

I've always loved El Segundo for some reason. Most people I tell this to don't understand why but it's just a very charming town to me. Even the old industrial areas west of Sepulveda and north of the refinery have a very cool feel. I love walking around that area and I've noticed over the last 2-3 years that a number of those smaller warehouse/industrial properties are being converted into office space for tech/ad/vfx companies.

The refinery usually offers a tour once a year for the public which is very informative and there is a great park at the top of a small hill off of Imperial Ave that affords what is probably the best view of LAX.

Sadly El Segundo's aerospace industry is slowly but surely shrinking. Plaza El Segundo, where that huge Whole Foods is, used to be a Honeywell fab if memory serves correctly.

Roughly 40% better compilation speed. Nice. Performance numbers from the bottom of the CL:

All benchmarks are from my 8 core 2.9 GHz Intel Core i7 darwin/amd64 laptop.

First, going from tip to this CL with c=1
costs about 3% CPU and has almost no memory impact.

Comparing this CL to itself, from c=1 to c=2
improves real times 20-30%, costs 5-10% more CPU time,
and adds about 2% alloc.

From c=1 to c=4, real time is down ~40%, CPU usage up 10-20%, alloc up ~5%

Going beyond c=4 on my machine tends to increase CPU time and allocs
without impacting real time.

If you've never started a company you can't appreciate how real this article is to the life of a founder.

Everyone in startup land is rah rah we're killing it talk. But oh boy if you're at least honest with yourself the reality is very different. You've got to project confidence to your staff and investors but for you circumstances are way different.
Taking a thread-oblivious program and making it multithreaded can be very hard. It requires global transitive knowledge of the function call graph and all shared data structures.

How was this achieved? Was it by a dev who was intimately familiar with the code base? Was it just applying the race detector repeatedly until it stopped squawking? Something else?

Yes. If it does biased good, it may not be doing good at all. For instance, there are claims that Wikileaks had the opportunity to leak RNC emails, and decided not to. It is certainly one thing to say that the DNC and RNC don't get to have privacy (I'm not sure I'd agree, but I can see the argument). It is another thing entirely to say that one of these groups doesn't get privacy and the other one does. Both of them make sausage. Both of them are American political parties. It's unpleasant, there's undoubtedly rampant corruption in both, and people are sending internal emails without an eye to the fact that the general public might read and misinterpret them. But if only one group becomes the target of Wikileaks, the general public will get upset at them and not the other.

If Wikileaks is controlled by some entity with an agenda, it is very easy to attack and embarrass and cause political problems for other groups, opposed to that agenda, and refuse to attack groups aligned with that agenda. No lies are required. They can release selective truth, and generate public outrage directed in a particular way, thereby clearing the path for whatever groups they like. Those groups would probably generate as much outrage if they were the target of Wikileaks, and we have no way to verify what Wikileaks themselves might be hiding.

It's sort of a Richelieu "Give me six lines written by the hand of the most honest man and I would find something in them to have him hanged" situation: they're hanging only the honest men they dislike.

(Also I'm sort of weirded out by your phrasing "They are wrong for thinking their thoughts" - I'm guessing you meant just "They are wrong to think" or something?)
Correct. If you tolerate, if you blindly allow, if you accept without action - you implicitly endorse.

Go's compilation unit is a package, not a file. This limits the amount of parallelism you can get compared to say C outside of the compiler. You have bottleneck packages like the runtime which have to be compiled before other packages, and in the case where you do incremental compilation you probably only have a few packages to compile anyway. Some of this is briefly touched on in the CL (see comments on the amount of concurrently that should be enabled), and there are issues on the bug tracker that go into more detail.
Great post, +1.

So in that case imagine there is a PARC bis somewhere out there... what kind of out-of-regular-folks wallet things they might be working on right now?

Hey there -- resin.io founder here. Resin is indeed starting with our hosted service, but we have committed to, and are making decent progress towards, building a completely open source platform.

If you need pure OTA, mender is a great solution. Resin is about containers first and foremost, with full-blown host updates being a lot more rare, since the host is a lot simpler.

Different things work for different projects, hope yours goes well!
As you well know, but to clarify for others, once the stock is vested - it stays vested unless you quit and don't buy it. Once you've vested the stock and purchased it - it stays "vested" as you own it - unless it's 83b early election of stock which is restricted, and that restriction retracts over time like vesting.
>I reflect on this story often, as it is a reminder that to those whose only concern is their next meal or the snakes in the grass, they need not fret the ghosts of the future or the past.

I remember when I quit my job way back. Stayed alone in my apartment for 6 months without seeing anyone and was drowning in debt learning a whole host of tech that was way out of my depth at the time (in order to find a better job, which I did). My now GF asks me how I 'got through it' and I have a tough time explaining that when reality hits you don't really have time to be depressed or feel anything. Just 'do'. Like some survival switch turns on.

It's a good story. My parents immigrated from a communist country after many years and they don't understand 'mental illness' or anything related. Every question is just met with 'there was no time for it'.

>> they would most likely even out 24-hour usage patterns rather than overstressing the grid.

Take a look at exactly how much power goes into an electric vehicle. I once worked out how many solar panels one would need to charge a tesla once per day in my local. The math pointed to something like a solid acre of land dedicated to sustaining a single car. (not an acre of panels, at my latitude you need proportionally more land on which to mount panels). A shift to all-electric transport would produce a demand for which LEDs could never compensate. Only the very wealthy would ever own enough land to actually self-sustain through renewables. Cities will need power grids for a long while.

Take electric transport out of the equation and things start looking much better. Hydrogen-powered vehicles would imho at least allow the possibility of "de-electrification" in north america.

In surfing, there is essentially no mechanism to compete short of a formal competition, which is actually not that popular. There are small pockets where you can find competitions, but for the vast majority of surfers, there is simply nothing to do but your personal best on every wave. It is quite pleasant compared to other sports. Admittedly, also not as aerobically intensive, so fewer calories burned.

Some people are paid to be heard, instead of spending their own effort on it.

This depends on how valuable one's opinion is in the eyes of the people around. If you think that the high-class people you hired after a lot of sifting for the best-fitting candidates are really valuable, and may harbor interesting thoughts, maybe an effort should be exerted to get these opinions from them, in the way comfortable for them.

Tbh the text editors in electron do try to squeeze as much as they can from the web API's. The VSCode tokenizer putting dense info in typed arrays as bitfields is a good example of someone understanding how memory access works under the hood.

However I do agree with you, getting into web dev is easy. Doing things closer to metal is harder. I would definitely love to do more low level C programming.

Oh man, I'm so jealous that you got the chance to talk with Yusef Lateef. That must have been awesome to pick his brain about music. He's one of my favorite musicians (alongside Coltrane himself of course). Eastern Sounds is still one of my favorite albums. He was one of those musicians who had a unique sound but was always trying new things.

Without defending the actions of the LEO, I'd note that in all probability, they were called in with just "We have a passenger who's been told to leave and is refusing to leave," and the implicit context of an unruly passenger instead of just one who refused to volunteer.

I wonder if that exposes United to the same vague class of liability as if they had SWATted him - they called the police in a way where they should have expected the police to use force, and they should have known that no force was required. It looks like the statute on disorderly conduct covers "reporting information when, at the time the call or transmission is made, the person knows there is no reasonable ground for making the call or transmission and further knows that the call or transmission could result in the emergency response of any public safety agency"; could a sufficiently clever lawyer argue that this happened?

This still happens! Silicon Valley gets a lots of long-term oriented funding from taxpayers via DARPA and other government agencies. Siri (named after SRI International where Engelbart did his work) and autonomous driving (DARPA Grand Challenge) are just a couple of recent examples.

In fact PARC still does too. Although owned by a private company, PARC does government-funded research.[1]

I would say generally people in SV are less consciously aware of the major role government funding plays in it to this day. It's probably because of the mythos of private entrepreneurship and the uncomfortable narrative of all this so-called "free market capitalism" being supported by billions in govt funds, with only a fraction of the profits returned to the public coffers via taxes.

Moore's law started out purely observational, but over the years it became a driving force of its own. Chip manufacturer's performance is judged against Moore's law. Roadmaps and timelines are drafted with Moore's law in mind. Massive research investments are undertaken with the expectation that they will enable a company to keep pace with Moore's law.

Even if you're not doing chip design, anyone planning more than one chip product cycle into the future needs to take into account Moore's law. If you're building a hardware system or even a software project, ignoring Moore's law means that by the time you ship, your product might be cheaper than expected but also missing features that are now cost-effective.
Interesting puzzle: one can leave out one letter, then another, and measure at what rate does understandability decrease for people (until eventually it's complete gibberish). Also, given a large enough audience, one could try different combinations of letter-removal orders and distribute those randomly, and measure the same... the question being:

* Which letters are the most vital to understanding written English? or

* Which combinations of letters? Are the letters the same in all the combinations of a certain rank, or do they differ? (where certain letter combinations themselves make each other more necessary) -- etc.

Alternatively: the same experiment, but where all words submitted by a user must match to a dictionary of real words. To that one may even add a grammar checker! (Which sets of sub-alphabets lend themselves best to proper English? Which allow for the shortest subsets? -- etc. etc.)

This would be utterly useless and I have no idea how it could be done.

The thing is, the hardest part of solving this puzzle, if one were to try, is not designing the experiment and writing the code, but figuring out how the hell to convince a massive audience large enough to collect the significant data to subject themselves to this experiment in the first place (or trying to design an AI that could be subjected to it -- and evolve the AIs themselves until they excel at deducing unintelligible text -- Would the results be the same for people and AIs?)...

I like this puzzle because it's so utterly stupid yet it would probably take an incredibly gifted person who has off-the-charts OCD to actually solve.

If I were a multi-millionaire I would hire a crack-team of engineers and mathematicians to work non stop on this particular problem; just for the hell of it.
