The survey includes a "primary cause of homelessness" section, of which loss of job forms a very weak plurality.

The increase since 2013 is reported to be only ~2%, (which I find slightly surprising¹) so it may be a bit loaded to ask where the "increase" is coming from. Since the last survey, the population even appears to have declined, slightly.

¹It feels like it has gotten worse, but that's only my impression, and I only frequent a subset of SF, so I may not be seeing areas that have gotten better. The survey is much more comprehensive than my anecdotes, of course.
So much this, to say "you only need x cores because the software can only use x cores" is a little shortsighted, because there's always stuff happening in the background.

Yes. My code is mostly AVX, so regardless of down-clocking I see substantial performance boosts.

But I've found getting into GPU computing extremely difficult. Admittedly, part of that may be having bought an AMD Vega graphics card instead of NVidea (not a fan of vendor locking, and AMD is building an open source stack with ROCm/HIP).

My code does lots of different things, many small, but given a billion iterations, it can add up.
If you're running a Monte Carlo simulation over millions of different data sets, fitting each iteration with Markov Chain Monte Carlo, with a model that has a few long for loops and requires (automatic) differentiation and some number of special functions...
It's not hard to rack up slow execution times out of small pieces.

Part of the problem is I need to actually find a GPU project that's accessible for me, so I can gain some experience, and learn what's actually possible. How I could actually organize computation flow.
It's easy with a CPU. Break up Monte Carlo simulations among processors. Depending on the model being fit, as well as the method, different computations can vary dramatically in width. But optimizing is as simple as breaking up all those computations into the appropriately sized AVX units (and libraries + compilers auto-vectorization will often handle most of that!), so wider units directly translate to faster performance.

Part of the problem is I don't really know how to think about a GPU. Can I think of the Vega GPU as a processor with 64 cores, a SIMD width of 64 (64 * 64 = advertised "4096), and more efficient gather loads/scatter store operations?

If there were a CPU like that, compiler + library calls and macros (including libraries you've written or wrapped yourself) go a long way so you can quickly write well optimized code.

I really need to dedicate the time to learn more. My 7900x processor is about 4x faster at gemm than my 1950x, but 10x slower than the Vega graphics card that cost less money. I see the potential.

To start, I need to find a GPU project that lets me really get experimenting and figure out how programs can even look.

It's pretty decent for the WiFi use case, but you could actually do something cooler with a symmetric PAKE if your WiFi device had a display. Pick a short random password, copy it over to the client, do SPAKE2. You now have a unique, high entropy secret -- and you have strong guarantees no-one else has that secret (an attacker can guess, but there's a tiny time window for them to do so, and the honest participants are immediately convinced foul play occurred).

As it stands, the PAKE is better than what they had, but not ridiculously better in the way U2F is over TOTP for example.
Yikes, slow down dude. I was posting it to point out that this is blatantly an advertisement for RtR, and that I don't want to read that kind of stuff on HN, not because I'm trying to blow your mind with this massively insightful analysis.
Thank you for taking the time to do this. I have found the referenced document quite valuable towards driving more rational debate around the subject.
One potential idea is a "pay it forward" model where you're asked to pay for someone else using the service, but only after you have successfully found a job.

When a job seeker signs up they would see that their subscription was paid by someone else and it will instantly build goodwill/stickiness for the product.

It's generally hard to monetize from job seekers since they don't have an income in many cases, but many would be happy to once they land a job and may even choose to buy a subscription for personal friends/family who are looking for a job. Similarly companies could also pay to buy X # of subscriptions for job seekers to attract people to their jobs and build goodwill/positive employment branding.

Could make for a good viral loop, could drum up some great PR, and help a lot of people

This is a tax bill, using cost-per-resident is not disingenuous.
Also, the "E[foo]" notation is something you'd pick up in an introductory statistics course. Which, IMO, means it's perfectly appropriate to use it without further explanation in this sort of context.

It's not really reasonable to expect technical subjects like this to always be presented in a way that's easily digestible to people who lack any background in the subject area. This article is clearly aimed at people who are studying machine learning, and anyone who is studying machine learning should already have a good command of basic statistics in linear algebra.
I dunno where you are getting your numbers from but currently 9700k is approximately 40% costlier than 2700x. $420 vs $280. Heck - I can walk into nearby microcenter can get both 2700x CPU + motherboard at $350.

Another interesting approach is the way Google Cloud Datastore/Firestore works. The query engine will only allow queries that scale and can happen in a single contiguous scan of an index range. The database can then stream results back and the work done is proportional to the size of the result set.

This way you can't do queries that don't scale in production, but still don't have to increase the cognitive load on the developer. If a query is rejected by the planner that (for the most part - it's not perfect) means the query won't scale.
> the much larger problem is SF's... failure to provide institutionalized care for people with severe mental disabilities

You can debunk this with a simple observation: Homelessness has grown significantly in the past 20 years. Has severe mental illness grown significantly during that time?

The bigger problem here is Stripe's argument is misleading. They're comparing cost-per-resident instead of cost-per-homeless-resident, when SF actually has a higher rate of homelessness than other cities. We actually spend less per homeless resident than NYC. Totally invalidates their argument that "if it's just a question of money this issue would already be solved."
Earthquake restrictions for one.

Seriously though, I was reading just yesterday about how they're developing Treasure Island and it has a high chance of liquefaction (not to mention radioactive waste) because demand for land is that high.
The 1-6 grading I haven't read before this article but since there is no information on how that contributes to the overall application outside of 1 (strong admit) and 6 (strong deny), it doesn't really tell us much.

Also, they never mentioned "quotas", just that they try to "looks at factors like parental occupation, which Mr. Fitzsimmons said offer clues about financial hardship, and intended major, to avoid having too many students with the same educational interests".
"Don't be evil" is still in the code of conduct: https://abc.xyz/investor/other/google-code-of-conduct.html
It is is you're trying to compare the effectiveness of spending money ("If homelessness was just a question of money, this issue would already be solved.") The relevant compare is cost-per-homeless-resident. We actually trail cited cities on that. How is Stripe's argument not misleading?
I mean RHEL Workstation is a very polished Linux environment. It might not be up to date enough for your needs but it's very stable and we'll documentated. Not the best for a laptop though.

ESA/JAXA BepiColombo Mercury mission launch livestream
A NSL can compel the recipient's silence in the form of a gag order, but the government cannot compel speech outside of very particular circumstances, such as consumer warning labels, that don't include verifiably false statements.[0] Thus the concept of warrant canaries, though they haven't been challenged in court.[1] There are other articles on both out there, but the EFF links are decent starting points if you're interested in reading further.

Making an explicitly false statement to preserve the silence about an NSL or its subject matter goes well beyond a gag order. The gag order compels your silence; it doesn't compel you to become an active participant in maintaining that silence beyond not acting to break it, let alone persuading people to believe any explanations or stories to explain it or shield the investigation the letter is a part of.

But there's another issue beyond the constitutional problems with trying to order Apple or its officers to make verifiably false statements about the existence of Chinese spy chips: any statement about said spy chips would constitute a material fact to shareholders. And it'd be a a really big one with an effect potentially measured in billions of dollars of market value, multiplied by the fact that Apple lied and destroyed every iota of credibility on privacy issues they've developed over the years. Making that statement--even if ordered to do so by an NSL--would be a blatant breach of the their fiduciary duty to shareholders and SEC regulations.

Even if compelled to do so, Apple (or its officers) literally can't make that false statement. They'd have no choice but to fight an NSL that orders them to make false statements, and even if they lost, they'd limit themselves to "no comment." So while they might be under a gag order on a given subject due to an NSL, if they're commenting about it, we can reasonably accept those comments as true. Or, at minimum, that they are their own words rather than the government's. As a hypothetical, it's plausible that they could be lying about the chips; but if so, it would be because of their own deliberate decision to do. Not that that's very likely, of course.

Why is Git with signed commits so uninteresting yet a "private blockchain" is?
The most marvelous thing about the Sagrada Familia (okay, second to how insanely beautiful it is for a Catholic cathedral) is the ticketing system: There are almost no lines to get in.

Every ticket you buy has a time and day- a 15 minutes period in which you may enter. And there are a limited number of tickets per 15-minute period.

This does mean you have to plan your visit ahead by a day or two, but you'll be rewarded with not needing to line up for more than a few minutes.

Operationally, the management have an exact steady stream of visitors from open to close, so staffing can be just as even, which I can only imagine reduces costs. And management can also tell if they've priced entry correctly by seeing if they have open spots all week or having three weeks' backlog sold out.

Could we please do this for everything that has a line up? It's a wonderful system.
Just because the program is running doesn't mean it's using any appreciable amount of CPU. Most applications spend their time waiting for IO, and when you're not interacting with them, there isn't any.

I think you're coming at this from the wrong perspective. The fact that someone is grappling with their sexual identity isn't by itself a qualification.

On the other hand, if in the essays or interviews you get the feeling that this candidate has matured beyond his/her peers as a result of it, or if this candidate demonstrates resilience dealing with growing up this way in an extremely conservative culture, then you'd probably consider betting on this person's upward trajectory. The context is important, and I don't think the NYT article captures it.
This seems absolutely insane, maybe someone can provide more context. Looks like a leftist government money grab to me.

The majority voted for 'none of the above'.
It’s interesting how both sides doubling down has observers relying on their existing biases. Most people’s stance seems to boil down to which one they’ve got a bigger ax to grind with- Apple/tech companies generally/intelligence agencies, or tech press generally/all press generally/Bloomberg specifically.
University security would not be adequate for the purposes of attestation for the level of stringency required. Universities are primarily academic environments that specialize in narrowly focused ideas and they hold up poorly to eg nation state level exploitation.

You're building something for the purposes of verification, not manufacturing; it doesn't need to actually build working chips, it just needs to scan them. So you don't need the same level of exacting precision throughout the design+fabrication process. And so it's easier to build in not just 1 "ooh, interesting", you could build in 1,000. I really do think so.

We now have precedent that maybe there's vested interest in hiding stuff. So security requirements would be so high as to make the project unviable because of its domain obscurity.

The above said, very interesting idea. I like it.

It's a very difficult problem domain though.
So in addition to having solid academic credentials, the ideal student would be from a rural place, a star athlete, potential humanities major (Philosophy, History, English), have parents with working-class jobs (chef, homemaker, construction worker), interesting or familial extracurriculars (film making, baby sitting), maybe an immigrant, maybe a racial minority, maybe not straight, but most importantly has great interview skills and personal recommendations emphasizing how outgoing, clever or mature you are.

Or your parents are super rich and can donate money for a new building or donate their entire art collection.
Not debating Apple's overall trajectory, but I think it's cynical to call this a step towards lockdown. Mitigating certificate forgery attacks ultimately increases trust in software distributed outside Apple's walled garden.

Then again, maybe he's playing the long game once people figure out the whole charade is Banksy selling out, the price of his work crashes, thus restoring its purity as self-expression.

So you want the insurer to provide insurance with unbounded downside? OK. But don't be surprised when the price of this insurance is very high.
Because it's a disingenuous compare. Stripe is leading you to believe that spending per city resident is a fair measure of the effectiveness of how we spend money. But it's actually spending per homeless city resident that's the correct measure of that!

SF has a much higher rate of homelessness than the national average, so that explodes the per-resident cost. But we actually spend less per homeless resident than NYC. Surprised?

Stripe knows all this. They have this veneer of plain spoken honesty, but take note of the trick they're trying to pull here.

Problem is, anywhere you go, you'll run into the local NIMBYs.

Or let's say San Francisco actually subsidizes some town out in Central Valley, I dunno, Hughson for the sake of argument, buys up loads of farm land adjacent to the town and turns it into a much nicer place to live because those dollars will go further, puts in some groceries, parks, a whole community basically. You've now turned Hughson into a much nicer town, and it will attract more people wanting to live there, and you're still subsidizing a whole other city in the process increasing the cost of living. Not to mention moving our entire homeless population there would effectively double the size of Hughson straining local resources and utilities, so probably a lawsuit and more money to subsidize it further.

So now you've done all of that, but since this is Hughson, there's no jobs except farm work, and the locals probably have that covered so now they need good transportation to the nearest decently large city (Modesto and Turlock) to find some jobs. Now that you've got this satellite city, how does it sustain itself? Because at some point, San Francisco taxpayers are going to start asking themselves, why are we subsidizing Hughson? Assuming you got them to agree to it in the first place (which you won't). City charter amendment hits the ballot, it probably passes, but the wording is so poor it has negative knock-on effects for all the other land the city owns outside of the county line (the Airport and Hetch Hetchy mainly), Hughson and Stanislaus County are left holding the bag on a largely unproductive neighborhood that is a drain on the local coffers and almost completely dependent on subsidies from people richer than them.

I'm sure by this point they'll be real excited about bulldozing some houses to make way for some bullet trains they were previously gung-ho about stopping at all costs, and depending on the legal status of the property left behind, they can either seize them because nobody is paying property taxes, or seize them with eminent domain and put them towards some new productive purpose that once again, leaves these formerly homeless people homeless.

This is still better than the alternatives: hoping the State of California steps in to do something about it (they won't because nobody in California likes San Francisco except people who live in San Francisco), or hoping the Feds step in (they won't because hating San Francisco and hoping it falls into the ocean is a national past time, as American as liking Baseball).

tl;dr we spend money trying to "solve" the "problem" locally despite the high cost of living because San Francisco only has San Francisco to depend on. Anybody in power that claims to like San Francisco doesn't actually like San Francisco, they just love our money.
