Pydantic 2.0 just released – An overview of the popular data validation tool
For reference, I pay over 65c/kw hour in the heat of the day, in California. It’s going up significantly shortly.

Their power is significantly cheaper. I naively assume this is a practical advantage.
Dumb question:

Say I have a wooden stick and I break it in half in less than a second. Assume a computer would need several minutes to simulate everything that would've happened in the stick. I clearly got the output faster than a computer (and with more precision), so does this imply I'm doing anything particularly fascinating?

I assume the same scenario is possible to concoct for a quantum computer. I assume it wouldn't be particularly interesting either. So what are the criteria for distinguishing those scenarios from the "interesting" cases? And how do we know which case this one is like?
I'd like to work for a team where if you have ab aesthetic suggestion like this, you're only allowed to leave a comment if you also submit a commit.

So the "actioning" part becomes their work.
did you bother checking what it was before coming up with two examples? it's quite blatantly placed...

It would be a lot nicer if the proposal for SVG 2 was ever adopted, but that has been stuck in draft for years. https://svgwg.org/svg2-draft/

I totally agree with everything you said (as a normal user of Matrix and this bridge) but shouldn't you clarify that you work for Element? You are a user but also more than.
The real question to me, is how it will take to get more (useful) qubits.
All the decrease in productivity related to remote workers is related to bad management. If processes and communications are standardized within teams, there is no productivity decrease. In my company, there is an increase in productivity. There are a huge number of extraverts who want to go back to a desk because they want to fill the day with useless meetings and coffee breaks.
I mean, it seems self evident to me.

Human perception + reaction time is eons compared to how quickly a computer can move the wheels and pedals.

Whether the machine makes the _right_ decision is much more difficult, but a computer can actuate with speed and precision humans simply cannot.
Yes...depending on battery discharge state and, rather violently, on how lucky you are on charger use and functionality. It is a large gamble in most parts of the US depending on times and luck. You absolutely couldn't plan a calendar appt around it without adding 30 minutes of buffer.

Also the point was around gaming, if you are gaming in the car in your garage instead of on a proper TV, you are spending your money weirdly.
Vannevar Labs | REMOTE-FIRST | FULL-TIME | Offices in DC and NYC

Vannevar Labs brings innovative, robust, and scalable software design to the public servants working in defense and national security keeping our country safe. As a team, we exist because we believe in public service, and we think that our democracy and government improve only if we put serious, collective effort into improving them, including the technology our government uses. Our founders have 30 years of combined experience across national security, government sales and CIA, In-Q-Tel, DoD/JSOC, Harvard, and Stanford. We are a profitable Series B company and are looking to scale out the engineering team.

We're hiring across a number of engineering roles - feel free to apply on our website https://jobs.lever.co/vannevarlabs-2
There are plenty of developing countries where people don't trust the government currency and use alternatives. It's quite common in Africa where many transactions were done in USD.
Why do you prefer shrinkwrap instead of npm's package-lock.json?
Thanks. I don't understand why it wasn't in the article in the first place.

Crazy that they added such a specific detail to a map that looks like ... that. I agree with Vietnam that it has to be a deliberate move towards being nice to China.
> Though in Factorio's case it's implemented with a lot of `if(saveVersion >= 0.17.123) xyz = stream.readInt32()` and compatibility gets dropped every few versions.

Blender does pretty much this other than dropping compatibility.

If a new feature adds another struct member you also need the ability to read an old file into the new struct. Usually (IIRC) you would just add a line or two to the function which deals with this stuff and set your new field to a sane default -- assuming everything is compatible because all changes aren't, trying to load something like the Big Buck Bunny models into a new version isn't going to work as planned.

The easiest way I found to add something new was to take over some padding bytes (there's a bunch) so the struct has the exact same memory size and the older versions just ignore those.
It depends on your setup and use cases. There's three major considerations:

* What language are you trying to OCR? And only language or also things like math symbols?
* Do you have a GPU or not?
* Are you trying to OCR handwriting or typed words?

I explored OCRing English documents from the 1960s that were primarily typed, though some handwriting. I tried out PaddleOCR, TrOCR, Tesseract, EasyOCR, and kerasOCR for FOSS, and then Google, Amazon, and Microsoft for paid.

To be clear, the paid solutions beat the FOSs ones handsdown, no question. However for FOSS I found that TrOCR was the best for both typed and handwritten, however for typed, it was closely followed by tesseract, but for handwriting TrOCR was by far the best with all the others basically being worthless. However, TrOCR took ~200x longer even on GPU than Tesseract on CPU (Tesseract if fastttt, even more if you parallalerize it). Tesseract isn't the best, but it's the best all around, it's the one the Internet Archive uses.

Need to write up a blog on this. And the docTR looks interesting, I'm going to check that out.
Seems like existing helmet HUD technology should be sufficient for some basic telemetry.
I worked for a while at an auto supplier (heavy vehicle like semis, buses, RVs, and military) in their test labs. The bean counting is real. I remember one test we had to do involved replacing a single bolt in a 200lb wheel assembly with one whose threads were 30% shorter and barely made it through the hole. It wasn't a clearance issue, per the PM and engineer, it was because shrinking that bolt saved half a penny per wheel end (or something small like that) and would put them under their targeted cost per unit, nevermind the hundreds of hours of testing that had to be run to validate the new assembly.

PMs are given a target price and a target cost. They will do everything in their power to get under it because their job depends on it. Those drives are going to be the bare minimum necessary for storing what they need to (not what they want to) and will likely have a very short lifespan overall.
You're looking at a misleading data point on two levels.

First, note that the 75.5% figure in that table includes Hispanic/Latino people, which not all sources will -- importantly the study I was quoting doesn't include these under "white", so we can't compare those numbers. There's a different row in your table that excludes those to get 58.9% white. This alone gets us back to the ALDC group being disproportionately white.

Second, it doesn't matter if 75% of the US population is white, but rather what percentage of the college-admission aged US population is white. (Not that people outside of the 17-23ish bracket don't apply to Harvard's undergraduate program, but I suspect that they do so in insignificant numbers.)

Here's a source that breaks out US racial demographics by age: https://nces.ed.gov/programs/digest/d21/tables/dt21_101.20.a...

It says that in 2021 amongst 18-24 year olds, 52.8% were white. Thus the ALDC group is even more disproportionately white than the whole-population number would make you think.
This is a good counterpoint to what was posed above.

That being said I feel like this is almost the obverse, they have a product that sells well so they don't need to follow each trend that comes out. So they can pick and choose which way they run with things.
When all this search engine 'things' came about websites were indexed organically.

Then websites started to optimize for what Google actually parsed. Meta tags, no things behind JavaScript, semantic markup etc. And that worked really well. Stuff was easy to find.

Those were the best days. There was some luring, but at least if you were looking for something technical you found it (provided it existed and was indexed).

This is no longer the case. Give you an example:

Any search term for Windows+Error+KB<number> is a nuclear wasteland of companies having copy-paste pages only to sell you their services at the end. Lately the same has been popping up on YouTube.

Any search for an issue with formatting a harddrive lists 20 pages which sell formatting tools.

A search for checking whether a certain animal is dangerous yields wildly inaccurate results just to sell me pest control. Spoiler: it was a Jerusalem Bug. You don't get a fever at all. The thing just has huge mouthparts, and that can physically hurt.

When you put "(recommended)" in your title because you know it's then displayed verbatim in Google is nasty.

All driven by these websites which 'recommend' things to you.
My understanding is that quantum computers only have two real use cases, as of today:

1. Breaking crypto.
2. Simulating other quantum systems.

For (1) it's basically all downsides. For (2) unless you're a particle phycisist you'll never need quantum computers.

But that's now. Maybe there will be a killer app for it some day, changing everything. Or indeed, we could get it indirectly. Maybe simulating quantum systems we could invent new battery technologies, which in turn changes our lives.
Norsk Data was one of the big guys producing minicomputers in the 70s and 80s.
Apparently they held on to minicomputers for too long and quickly lost business to Sun and workstation manufacturers in the early 90s.

> He said: “This is a very nice demonstration of quantum advantage. While a great achievement academically, the algorithm used does not really have real world practical applications, though.

> “We really must get to utility quantum computing – an era where quantum computers with many thousand qubits actually begin to deliver value to society in a way that classical computers never will be able to.”

This seems to be the most level headed take from the paper and an explanation why (if claims are to be believed) we haven't seen anything useful come from quantum computing yet that couldn't be done by classical computers.

Maybe it still is all hype and the reason we haven't seen a useful calculation is because the only problems it can solve better than others happen to be especially contrived. I guess time will tell.

Here's what the person you're responding to said:

The article includes a (entirely made-up speculative) growth projection, which says it will grow very differently from the iPads.
Isn't a hardwired GPU a bad sign for future proofing? Isn't an HDMI port and a power connection a good sign for future proofing?
> If you had a remote MIDI sequencer that users could connect their musical instrument to, it would almost certainly have something like a Web interface as well...

Not at all. There are tons of MIDI devices which communicate over MIDI, and which don't have another network interface. Most electronic keyboards fall into this category, for example.

> MIDI isn't by itself an internet protocol, which I'm sure you already know

AGPL doesn't care. MIDI is a network protocol; whether it's bridged to the general Internet is irrelevant to the license.
Trunk and access ports are like kleenex and bandaids. Yes, technically cisco terminology, but used everywhere.

Typo, you listed five roles.
There is nothing unusual about this, except for the fact that Germany's state support extends to a plurality of churches rather than just one. Before the disestablishment of state churches, it was natural and common for the state to support the Church, including through taxation and mandatory tithes. My Greek friend informs me that Eastern Orthodoxy is still run this way, but more straightforward since there is only one established Church to fund and operate. I am not sure how many other Orthodox nations support their established Church through taxation, but yeah, it's normal.

Exactly. I'm OK with ads on YouTube if they are placed in OK positions in the videos. For example, if they are placed in a natural break in the video. However, YouTube has decided to destroy their user experience by placing the ads to maximize "user engagement", aka, "where is the worst spot we could put an ad in the video?" For example, take a slow mo guys video. They will place the ads right as the interesting section of the video is happening, say when the water balloon is hitting the guy in the face. At that time, I'm definitely watching the video, so I see the ad, but holy cow do I hate YouTube and the advertiser for interrupting the best part of the video. I'm tempted to get Premium just because of this; however, I feel like I'm giving into YouTube making their product more shitty to make me want to get Premium. I don't want to reward them making their service worse causing me to give them money for the experience their product used to be.

> "I'm not sure what to think about all this. On the one hand, I'm happy that I was able to get a 25x-50x speedup on my site. On the other hand, I associate speedups of that magnitude with porting plain Ruby code to optimized C++, optimized C++ to a GPU, or GPU to quick-and-dirty exploratory ASIC. How is it possible that someone with zero knowledge of web development can get that kind of speedup by watching one presentation and then futzing around for 25 minutes? I was hoping to maybe find 100ms of slack, but it turns out there's not just 100ms, or even 1000ms, but 10000ms of slack in a Octopress setup. According to a study I've seen, going from 1000ms to 3000ms costs you 20% of your readers and 50% of your click-throughs. I haven't seen a study that looks at going from 400ms to 10900ms because the idea that a website would be that slow is so absurd that people don't even look into the possibility. But many websites are that slow!"

No, that is not what I am arguing. Please reread the thread.
Couldn’t agree more. And I’m not even catholic. The German catholic Church is often in open opposition to Rome, and in general behaving like the typical LinkedIn Company profile page during pride month.

The catch with switching from RHEL to SUSE (or Ubuntu, or whatever), is what does your vendor support?

Big fancy medical records software at the hospital? It used to run on either RHEL or CentOS. They stopped supporting 8. They won't do stream. You only have to buy one Red Hat License (unless you want to run CentOS 7.9 for the next 11-12 months), and it's tiny in comparison to what the actual software license and support costs, and we won't even get into the hardware that you're required to buy.

What prevents me from cloning some product's website and changing the payment form to send me the details instead, which I then submit somewhere else to purchase something online for myself? Not sure why Stripe or PCI is even important here.

(IMO) what GP was arguing for is that we should have a fundamentally asymmetrical form of payment, viz. the information I give for one purchase should not be able to be reused for another purchase, like a one-time token. Imagine if you had to send your private key every time you wanted to purchase something in crypto, for example.

I've been tooling around with "Tuple Database", which claims to be FoundationDB for the frontend (by the original dev of Notion).

https://github.com/ccorcos/tuple-database/

I have found it conceptually similar to Relic or Datascript, but with strong preformance guarantees - something Relic considers a potential issue. It also solves the problem of using reactive queries to trigger things like popups and fullscreen requests, which must be run in the same event loop as user input.

https://github.com/wotbrew/relic
https://github.com/tonsky/datascript

Having a full (fast!) database as my React state manager gives me LAMP nostalgia :)
My take: AI is a fad just like crypto was before it. Who can even remember what was the toy of the day before that? Maybe Facebook social apps? It will end same way as all the previous ones: 200 smart people will offload some of the fools' life savings into their pockets and move on to the next "big" thing.
