I thought everything was a dollar!

Yes, although it's not like it's constantly streaming your camera to the cloud. These things are basically Bluetooth webcams connected to an app on your phone, so they only send snapshots or short video clips when requested. Local processing is minimal, and if you're offline you can only use basic voice controls to take pictures or record videos.

Sure, but if we're going to gatekeep employment and advancement behind a system that rigidly demands that you work well under time pressure, a lot of people never get to find something suited to their abilities.

I myself barely made it through university because I'm terrible at taking tests. I've been successful in my industry for almost 30 years now. But I was gated by the same tests as everyone else.

Some parts of the working world are a lot more forgiving than you're giving them credit for, especially now that remote work is a thing. Over the last few years I've watched companies drop the programming test from their hiring process—including Epic—because it didn't get them the results they wanted. They accidentally selected for people who worked well under stress, but 99% of our jobs aren't like that. They got better results with interviews that involve a lot of talking to reveal the things that you know.

In Canada, someone did a study of how much it cost to administer NSERC grants (a very prestigious, large grant for doing science research) vs. how much it would cost to just give every applicant what they asked for, and it was CHEAPER to give out the money than scrutinize each grant for its worthiness. Where's the value in withholding the money? There's good science that doesn't get funded and instead bureaucrats shuffling papers eat it all up trying to understand grant applications that they're not qualified to inspect.

You will definitely get people working the system in these cases, but there's an argument to be made that more accommodation will just give better results overall. Just give EVERYONE more time on the test. 100% of people get 6 hours to write the test. The people that are now trying to 'take advantage' of the system are returned to a level playing field. The people that need that time because they're neurodivergent don't have to ask for it. You get to see if people actually learned the material. There's little practical downside.

Crosswalks are dangerous.

A particular danger at crosswalks is cars making turns. It's often hard to see pedestrians when other cars are blocking the view. (And bicycles are always something to watch for.)

Because the JTEC is an evolved version of the older AMTEC, Alkali Metal Thermal-to-Electric Converter, in which the working fluid was liquid sodium. The version with hydrogen is much easier to work with. AMTEC looked great in small-scale lab experiments, and for a while in the 90s they were heavily pushed as the successor technology to thermoelectrics currently used in radioisotope power systems, but turned out they were too hard to work with. (I still kinda like the technology, though. It's thermodynamically elegant.)

There's also a JTEC variant that uses oxygen, I believe: https://www.researchwithrutger...

If the article had compared it to existing sterling engines and mentioned how it was better than existing Sterling Engines, that would have made it interesting.

Stirling engines actually work but don't return much in the way of mechanical energy for low heat differentials. The usual deal with attempts to scale up and commercialise Stirling engines for electricity generation or other use cases normally involves choosing hydrogen as the working fluid because it's closest to being an "ideal gas" and hence more efficient than the alternatives. The rest of the research budget is spent trying to contain the hydrogen gas with seals etc. before bankruptcy beckons. Step and repeat.

This re-invention attempts to get round the "blow a seal" problem by using fixed but flexible membranes to contain the hydrogen. I can imagine other issues with this technology that could cause problems in both the short-term and long-term but I'm not sufficiently knowledgeable about the materials etc. involved.

I'm a lead programmer in the games industry, and I did not show up to meetings with low value. But that said, 50% of my time was spent on meetings and managerial duties.

Critically, I consider it my job to go to meetings so the other programmers on my team DON'T. We need to talk about the state of the game. We need to discuss mechanics and timelines and all sorts of things. But I don't want other programmers in more than a few hours of meetings a week, and most of those meeting hours should be just in our team giving and getting updates.

We were aggressive about cutting meetings that people felt had little or diminishing value. Sometimes meetings are useful for a time and then they're not. I never went to a meeting that I was invited to where I didn't feel like I needed to hear the information or present something useful. Guard your own time, no matter what level of worker you are.

But yeah, useless meetings feel terrible. I didn't feel bad about the meetings I went to because we often accomplished a lot.

Nah, the deals on used EVs are great right now; I think more people are going to start buying them up. They have low maintenance and running costs, and for around town, they're great.

There are so many goddamn F-150s on the road belonging to people that never tow a single thing or load the bed up. They're commuter cars for accountants with masculinity issues. Don't tell me that we shouldn't get these dipshits into normal cars or EVs both for the sake of the environment and road safety.

Autism is a much broader category than it used to be.

There's actually some evidence now that ADHD and Autism are on the SAME SPECTRUM, they're just different manifestations of slightly different brain wiring. For some people, it's more of an impediment, but fundamentally, the impediment is that we don't allow those people to be themselves. They might stim by flapping their hands a bit or moving around (I have ADHD, and I ALWAYS have to have something in my hands during meetings; I also 'pain stim', where I might press the tip of a paperclip against my finger. It doesn't HURT hurt and I don't break the skin, but the stimulation is something that I do basically unconciously).

Anyway, when we talk about neurodivergence, some people need little to no accommodation and some people need lots. I actually don't think having tight time limits on tests makes any sense. In my work, I get lots of time to research and figure out answers, and if I do it enough, the answers become easier to come up with. Are we trying to test whether people know things, or whether they deal with time pressure the way we think is necessary (again, for no good reason).

You gotta pay people to monitor the exams anyway, just let people have the time they need. If they get 100%, great, they know their stuff. What's the issue?

Just put it in context: Today Russia struck the Pechenihy Reservoir dam in Kharkiv.
Russia launched the war because they thought it would be a quick and easy win, a step towards reestablishing a Russian empire and sphere of influence, because Putin thinks in 19th century terms. Russia is continuing the war, not because it's good for Russia. I'd argue that winning and then having to rebuild and pacify Ukraine would be a catastrophe. Russia is continuing the war because *losing* the war would be catastrophic for the *regime*. It's not that they want to win a smoldering ruin, it's that winning a smoldering ruin is more favorable to them and losing an intact country.

It's more as if there were a Diagnosis of Seeing Manual (DSM) that redefined the definitions to merge blindness with other vision problems into a single category, a spectrum "Visual-acuity spectrum disorder". So people who previously said "I'm blind and need accomodation" now get put in the same category with people who say "I have visual acuity spectrum disorder" because their vision is 20-40.

Autism most certainly does exist. The difficulty here is that in the most recent DSM, autism was redefined as a spectrum, and the "mild" end of the spectrum manifests as socially awkward. But there's no clear dividing line anymore; neurotypical behavior can shade into socially awkward behavior by infinitesimal degrees. And, worse, in the popular conversation about autism, most people talk about the mild form, previously a separate diagnosis of "Asperger's", and the profound version gets ignored.

I've read MRI scans require helium, and there is currently a shortage. It's not practically renewable or recyclable so far. If everyone gets an MRI it could cause a severe shortage.

I wonder if the tech can be reworked to not require helium or any other hard-to-find resource.

Nobody was doing strained-layer epitaxy in the 1950s.

Yes and no.

Visible light carries energy, and hence, yes, absorbing visible light will heat the fabric. However, at temperatures less than a thousand degrees or so, most of the heat energy is carried in infrared light. Since the fabric is specified as being black in visible light, it may or may not be absorbing in infrared.
