Those test swabs work quite well. They are designed to test ceramics, clay etc. You can find them in pottery supply stores.
If trying on food,I would soak or boil that food to reduce water and thereby increase concentration if there is any. You could add lemon to the water, as acids (vinegar for example) help extract metals.
The problem is you don't get an actual number, just over a certain limit.
I think it might be 50 ppm.
But it's been twenty years, so please check that number.
Alternative is to send to a lab, ask for a 32 element icp. Should cost between 50-150$, especially if you state you don't need chain of custody proof. You will get 32 elements. Which is fun.
(Can even look for gold, but that's extra $ testing.)

Lead naturally occurs in the environment, depending where, in the world you are, from 2 to 20 even UpTo 50 ppm.
Industrial/commercial sites are common to have up to 150ppm.
Contaminated toxic sites way over that, over a thousand. We could go on.
But the swabs work as a starting point.

You're thinking of Transnistria: https://en.wikipedia.org/wiki/Transnistria

The history of that area is complex. Moldova itself was part of the Ottoman Empire, then it was ceded to the Russian Empire, united with Romania, then the whole are became part of the USSR... and after the dissolution of the USSR, Transnistria became an unregognized, but de facto autonomous "country". Moldovians see the area as still part of Moldova (with some still considering the whole country as part of Romania!). The EU sees it as a Russian-occupied area since Russia supports the local government, and without Russian support the Moldavian Government would've probably taken over the area already (it's a frozen conflict area... Eastern Ukraine is headed for the same destiny, it seems).

Charles Simonyi and his Intentional Software tried to solve this, publishing some interesting articles in the 1990es. However their technology was not broadly used and they were acquired by Microsoft.

The key ideas are called Intentional Programming and Language Workbenches.

The best accessible implementation of that is JetBrains’ MPS (it is free). It allows you to define a language and “projectional” editors together.

It is really fascinating but it suffers from a learning curve where there is no small step from what people use in their everyday common languages and IDEs to building domain-specific solutions with MPS, so adoption is low.

Markus Voelter has some highly recommendable publications and elaborate applications of MPS for domains specific languages, see http://voelter.de/

I am sure there is something great in that area but it has not found the right form and shape yet, so keep exploring.
It's different category of computer, designed as an appliance, like my car stereo, which is also a computer. The value of Apple computers is that they're more general-purpose than a gated cell phone.

There’s no proof of decline and death being “intentional” (as much as nature has intentions). At this point it’s just as likely that our bodies just tend to naturally poison us with glycated connective tissue, transthyretin, various peptides and what have you.

The idea of adding plastic to the soil (that's what I'm reading polymer as) to improve crop yields sounds reasonable IFF the polymer also degrades reasonably. Given that caveat, sounds like a shortcut to getting some of the moisture-retaining properties of high-carbon soils without the pain of transforming dirt to that kind of soil naturally.

Lead poisoning is quite common in suburban and urban areas, when houses / buildings are demolished. There's a huge plume of lead and asbestos dust that is generated, even if the contractor is making some effort to wet the site.

If a building or home in your area is being demolished? Don't open your windows, and don't go outside without a well-fitting dust mask. Never attend a building demolition event.

Contractors and developers are supposed to take measures and inform local government...if they're stupid enough to inspect for lead / asbestos before construction and declare that they're doing asbestos / lead abatement. Every piece of regulation and law I've found uses a very fascinating phrasing - you're required to do things if conducting abatement.

Many states go further and exempt anything under a dozen or two units or commercial buildings. It's an absolute shitshow.

Is it that they're bad, or is it that your tests stumble upon a small area in the huge realm of software engineering that those particular engineers struggled with on those particular days? Or, if you're asking these people the same group of questions and seeing a 90% failure rate, maybe your chosen questions have little overlap with common engineering tasks?

One of the things that can be tricky about this happens when you’ve legit worked in a few languages and the semantics are perfectly clear in your head but the syntax for any language you haven’t used recently is crowded out by those you have.

I needed a small perl script recently (perl 5’s feature set & stability plus availability in the environment made it the right fit) and realized after 15+ years of no perl much of the specific syntax was fuzzy to outright gone from my head even though I’d contributed to large perl projects for years.

Python work is much more recent, but I’d bet I would accidentally mix in some JS or even PHP syntax doing the dictionary assignment, at least w/o a cursory lookup. I’d like to think it’d come through that I know what a dict is and what it means to set one up and operate over it, but who knows, I might be interviewing with someone who is evaluating skill on the basis of immediacy of syntactic recall.
I like it. This fondly, yet somewhat bitterly, recalls memories of my 25-year-old self creating his first HTML page in 1995, or even my 10-year-old self writing his first BASIC program in 1980.

I dont know man, my school is not a global top 50 but it was a public engineering school and the CS degree I got was extremely valuable. I think you are being too strict with that "global top 50". It depends more on are you learning a skillset that an employer can find useful?
My somewhat limited understanding of LLMs (and ML in general) is that you would end up using a LOT of bandwidth, not to mention that training would be insanely slow, since each layer of the neural network requires the results of the previous layer, and then needs to send its results back.

The greatest limiter for training isn't raw computing power, but storage. If your model is 400B parameters, you need 800GB to store it, assuming fp16. Then you need another 800 GB for calculating gradients. Sharding all this out means transferring a lot of data. If your device only stores 1B parameters out of the 400B, that means having to download 2 GB of data, doing your share of the work, then uploading 2 GB of results. Even with gigabit internet, you'll spend an order of magnitude more time transferring data than actually processing it.

At that point, it'd be faster to train on standard-specced PC that had to constantly page out most of the model.

Ah yes, Excel, the piece of software that already famously mangles data, is now going to be glued to software that also famously mangles data.

Honestly, though, I kind of kid - I love spreadsheets, and if this actually works, it could be interesting. God help whoever needs to troubleshoot the hallucinated results - it's already hard enough to figure out what byzantine knotwork someone created using existing Excel functions, but now we'll have to also guess and second-guess layers of prompts that were used to either generate those same functions, or just generate output that got mulched through some AI black-box.
I see. However, 32x32->64 multiply has been common on 32-bit processors since the mid 80's. It would be interesting to know if somebody is still building new products on (32-bit) processors that lack it.
> or I feel too old to really hang out at some of them (some trendier bars).

Do you live in a major city?

I just turned 40 and I live downtown in one of the busiest neighborhoods for nightlife. I have a huge group of 25-50+yo friends, male and female, who all eventually meet up at mostly one specific bar but we do bounce around and go do other things around town. I moved to this city without knowing anyone and after 2 years I'e got friends all over the place, some are literally next door or across the street from me.

I say this as unless you're talking about younger trendy bars, like more EDM cocktail places, that's probably a bit younger crowd but the bars (dive neighborhood bars) I hang out at are almost all people in their late 20s or 30s. I don't but a bunch of my friends have teenage kids and I still see them just about every day.

The youngins (21ish) mostly come out to my bars late Fri and Saturday nights, like 10pm+. If you hear Babyshark on a karaeoke machine you should just avoid it because it's zoomer night and you're going to hear these songs over and over: Abba - Gimme Gimme, Babyshark, and that ra ra Rasputin remix. If a song goes viral on TikTok it's getting played 10x that night. I RARELY see my friend group out that late because those nights can be hellish with all the sloppy drunks but sometimes it's entertaining.

Anyway, you're definitely not too old. 30s the new 21 or something. I hate encouraging drinking but I finally just came to the conclusion that I really enjoy going out and socializing and beer just happens to be there so stay fit and try to moderate and watch my liver.

I have horrible cabin fever from WFH for 4 years straight so I go do something almost every single day after work lately. And I am MUCH happier than when I wasn't doing that 2 years ago.

Hope you find your way soon.
I found better results with LinkedIn in promoting my business and getting site visitors. It’s so satisfying when something eventually works! Tbh I am surprised as I wasn’t the biggest fan of LinkedIn in the past. On the contrary, reddit has proven very difficult to promote anything. HNs is also tricky, so many posts lol. Facebook groups relevant to you are anither option! I also find that organic growth and referrals from close trusted friends have higher success rates at sharing your message. All the best!

Take a look at your city's community classes and see if there's anything you're interested in! A few years ago I took one of the pottery classes that my city offers and it's great for getting out of the house and socializing while also working with my hands so that I feel less like I live on the internet.
Doesn't have to be pottery, lots of cities also have classes on cooking, painting, dancing, all kinds of stuff.
It's a lot of fun and was pretty much the first time I felt like I was part of a community in my city.
A necessary part of a heat pump is a way to move the heat away from where it was collected, so that you can either reject it (if you are cooling) or pump it into a space (if you are heating).

How do you do that with a solid metal? Do you have a complicated setup of hot room air blowing over the metal to absorb some heat, and then pump outside air through the same cavity to take away that heat? That sounds mediocre, as air is a pretty crummy working fluid for heat pumping.

If the refresh rate is high enough, a single LED could flip between multiple wavelengths to dither to non spectral colors.
My ultimate hope is that this will allow us to store and display color data as Fourier series.

Right now we only represent colour as combinations of red, green, and blue, when a colour signal itself is really a combination of multiple "spectral" (pure) colour waves, which can be anything in the rainbow.

Individually controllable microLEDs would change this entirely. We could visualize any color at will by combining them.

It's depressing that nowadays we have this technology yet video compression means I haven't seen a smooth gradient in a movie or TV show in years.

When removing extraneous modifiers, it takes the form of "[article] [subject]" -- "A thanks."

Similar constructions would be "A cucumber." "The house."

Well yeah, Belarus is essentially off-limits to a large part of the world due to Russia's war with Ukraine.

Belarus does seem like a wonderful country at its core, but after the election fraud all progress just froze and the country is (once again) seen as Russia's de-facto vassal state. This sucks for the people of Belarus who got caught up in this, but for the average tourist going there is not something to consider.

The travel advice for Dutch tourists, for example, is literally don't; this country is not safe for holidays. And that's ignoring the additional warnings for LGTB+ folk.

A company like Google (or Apple for that matter), with their own freewheeling project systems, would rather jump into an olympic pool filled with razor blades and used condoms before taking any amount of money from the hellish morass that is the defense procurement system. The instant you enter the MIC, kiss goodbye to any of your internal business systems - you will be re-writing the way you work every second of every day. And not for the better, I might add. I think Google looked at the costs of that, looked at the contract, and said, nah, thanks, I'm good. Then went back to feeding NSA/NRO for black money delivered by men in coats.

Of course, now, post-ZIRP, things are a wee bit different.

It is not possible to reuse a single connection better, if we're talking about postgres. You must conduct the transaction over a single connection and you cannot mix different transactions simultaneously over a single connection. That's the way postgres wire protocol works. I think that there's some rudimentary async capabilities, but they don't change anything fundamentally.

It might be different for some exotic databases, but I don't see any reason why ordinary JDBC driver couldn't reuse single TCP connection for multiple logical JDBC connections in this case.

This is actually great feedback (even though on the surface it looks like a "your idea won't work" message).

This is a logical fallacy. The interviewer doesn't know if the interviewee is a great engineer or not, that's the whole point of doing an interview in the first place.
I agree with you, but for shits and giggles, to modify this to be evangelist compliant, you could write this instead:

In the best-selling vehicles of 2023 the most popular Toyota truck (the Toyota Tacoma) is only place 11, far behind the trucks from Ford, Chevrolet and RAM.

And that trucks are that popular at all is already a symptom of the "issue". Most people who drive trucks would be served better by hatchback, or if you want a bigger front grill an SUV. But trucks are cooler, manlier, more American. Which isn't an idea people got on their own. Which isn't an idea people got on their own, it's carefully cultivated in the US.
