The comment about powering a few anemic lightbulbs on 60W was assuming 12V, but otherwise it's all pretty independent of voltage.

You could get the current 1800W of energy out of a branch circuit with 15A at 120VDC and all the limitations/massive wires I described.

If you wanted to run 1800W DC as we run current power (14/2, hundred foot+ runs, etc) you'd be looking at something like 720VDC at a couple amps.

There's three main things I see as limitations to really pushing DC up to those levels:

1. Safety, plain and simple.
2. Switching. You generally require larger contacts and bigger gaps to switch DC because you don't get the benefit of it crossing over a 0 point several times a second. This gets worse the higher the voltage goes. This requires much more involved switching equipment. E.g., it's common to see a relay rated for switching 120VAC/30VDC.
3. Economies of scale. This one isn't some law of physics, but most current equipment you can find is 12/24/48VDC outside of very expensive industrial stuff. Also you're gonna need some pretty big transformers to step this stuff back down to usable voltages since everything we need it for is generally running at single-digit voltages. (Efficient, but just another big thing on the BOM for every single device.)

That said, I'm just a hobbyist so I may be missing something fundamental here.
Yup, it's no different than any company that needs to localize a market.

I think my favorite one is what happened with Kit-Kat, the chocolate candy.

In Japan, "Kit-kat" actually means "You will surely win". So people started frequently giving them out as gifts or good luck charms (till you eat it, lol)

But the market grew so much they started making all kinds of flavors, especially the "high-end" market with better ingredients and such.

Computers solve a lot of problems, as long as those problems are digital by nature. So naturally taking over an amateur mathematician who made his living as a computor, that was an obvious one. And we've gone through a cultural transition to solving all our problems digitally: using the internet to get all of our information, listening to digital music that is in a way a nostalgia of what the real sound was like, even trying to get machines to do 100% of our driving.

Blue collar? No, it doesn't work digitally, a huge amount of a blue collar worker's knowledge is not in his skull, but in his hands. Computers are remarkably bad at solving analog problems, just witness how terrible online dating is, it sucks. Or online classes, a totally inferior substitute.

Unlocking your phone does not fail safetynet. Installing a custom ROM _can_ cause a safetynet failure, but it is possible for ROM developers to pass it. In other words, for most phones, safetynet shouldn't be a major barrier to unlocking.

Rooting, on the other hand, does trip safetynet unless you take extra steps to hide it.
They have problems, but only insofar as any imperfect solution does. Having societal defaults itself is really good: If someone's confused as to what theyb should do with their life, bam. Here's a recipe that worked for your ancestors for ages, following it is unlikely to fuck you up badly. (This is, of course, a far bigger phenomenon than simply what jobs are called)

The freedom to define yourself is a good thing, but most people neither need nor want it, and for many who want it undertaking the excercise is a mistake, because it's more flippant wishy-washyness or deliberate, willful ignorance than self-building, per se. Consider the classic case of the Starbucks barista with a degree in postmodern dance theory.
Here in Saskatchewan, it was unusually dry this year, so the amount of hay was way less than normal. I heard figures like 10% to 20% of normal in some areas. As a result, the price of hay went way up, and some people are getting hay from as far away as Ontario. Also, there was an increase in hay bale theft. The thieves typically come to steal the bales in the middle of the night.

The 'type +++ath0 to speed up your download' jokes still exist.
The idea of a metaverse of some form or another falls out as a consequence of an assumption that there will be devices people wear that allow software to fully override their visual and auditory experience. These kinds of devices in their most rudimentary form have already arrived for experiences that do not incorporate the physical world (or other people in the physical world), but the ones that fully "close the loop" on physical reality being incorporated into the rendering pipeline will arrive in 2022.

There are no great incentives for Meta or whoever to make their vision of the metaverse align with the openness of the web or Internet, other than perhaps a desire by their leader to do something good for the world to cement his legacy. So this is why it is important smart people work on providing alternative visions, as oppose to writing off the entire thing while the future arrives and we're left subject to corporations because the nay-sayers didn't understand what was about to happen.

you’ve just failed your own test, since you don’t understand how and why a jury works. if you did, you’d comprehend that the better solution is expanding juries, not testing jurors. i’ll let you work out why that would be the case, and perhaps come up with an even better option as a result.

I am sure Linux is fine, if they want it, for everyone here. But my wife is not at all confident technically. I recommended a Chromebook for her to move off an underpowered Win 10 machine. She is very happy and self sufficient on it. I suspect most people out there are more like her than us.
Oocytes are one of the most difficult cells to engineer as well... The mitochondria in Oocytes are turned off from birth because otherwise reactive oxygen species will damage the mtDNA. One would have to use CRISPR to re-build the mtDNA, use telomerase / crispr to get the telomeres to exactly the right length, fix any mutations within the genome, etc. There are many many technical challenges to overcome, requiring further development of multiple immature technology stacks, and the bar is much higher than it is for mice since you would want a baby with the cellular metabolism profile of a 30y/old.
On a different note but not allowing student debt to be dischargable is a crime against humanity. This caused massive inflation in higher education costs and millenials got caught in this trap. There’s so many stories of people paying 5 figure student loans for decades and all that is because politicians value banks over the vast majority of their citizens.

Why is no one looking to reverse this horrible law?

I disagree with using the SDK directly because the SDK doesn’t have any reconciling capability, and that’s not something easily built correctly.

Creating resources with the SDK is easy—keeping them in the desired state is very hard.

Instead, we use a real language to generate a description of what we want (in YAML or HCL) and a reconciliation engine takes over from there.

There's a reason. It is Google and its Compatibility Definition Document: https://source.android.com/compatibility/ So no: OEMs that want to market their phones as running "Android" cannot break things as they please.
I agree, I’d pay a little more for a mechanical version.

I checked your link but I don't quite get it. Is status=0 supposed to be a check rather than an assignment?

Either way, it doesn't have that behavior like that for me on Debian: it behaves the same as bash. This is in dash:

$ command -v whoami
/usr/bin/whoami
$ echo $?
0
$ command -v echo
echo
$ echo $?
0
$ command -v nonexistent
$ echo $?
127

So that is with both a proper command (whoami), a shell built-in (echo), and neither (nonexistent). It's all as I would expect from a shell.

Bash does exactly the same, although dash chooses 127 as exit status and bash chooses 1 but they're both nonzero (thus error statuses).
Simply keeping physical distance has the same effect without the wrong connotations. Many in Germany understood social distancing as a kind of social isolation.
Also this social distancing has the opposite effect for me, since home office I have more social interaction as before, so social distancing increased the physical distance and decreased the social distance for me.
> However, the supply of power would be similar to nuclear baseload as it would be able to deliver at least 8 hours during any peak demand for more than 363 days in the year

Nonsense. A nuke plant delivers steady power 24/7/365. Solar cannot do that without some way to store the power and release it when it is dark.

You typically will need 3x the capacity of intermittent sources to replace a base source like a nuke plant, plus some sort of batteries.

TAO has supported single-shard atomic updates forever but this work is about cross-shared transactions. I left a few years ago as well and this didn't exist at the time.

There have been major changes in the shipyard since the fire. Navy leadership, RMCs, and ship's force have been more involved at every level. The question to follow now is when will they return to complacency.
I think it's much more a matter of negative real interest rates. This inflates the price of all assets, but especially real estate, which is available to be purchased with the cheapest fixed-rate leverage around.
To the Navy’s credit it does appear they’re chopping some heads over it (even calling out the ships previous captain and some civilians) and perhaps this wake up call will help reorient the navy back towards where it needs to be. It’s certainly better than pinning this entire event on whatever E-3 started the fire.

Can’t say I’m super surprised it’s reached this point though, we’ve been running our military like schizophrenic kids on adderall for the last 20+ years.
To clarify my comment: obviously text will never be "obsolete". But I worry that some day when you search for something like "how do you reverse a linked list", the most popular results will no longer be well thought out articles, perhaps with good use of pictures, and maybe animations when necessary. Perhaps in the future the most popular results could be a video, perhaps also well done, but advertised with clickbait and constant "like and subscribe" and "sponsored by <some product>".

I am curious to see benchmarks on promised improved perofmance and reduced battery usage. Are there any?
It would be consistent with my repeated personal experience if promises were made to this woman and then not kept. Higher academia uses all sorts of dark patterns on students.

In two summers of undergrad, I was "casually" promised a summer stipend by a lab which went on to vigorously avoid making it concrete or putting it in writing until I twisted their arms with a competing offer. I don't know that they wouldn't have paid me, but I later learned that they had done this to other students, so it's a thing that happens. When I was applying to PhD programs, my favored lab accepted me on the understanding that I would be funded through a particular grant and "discovered" after the admissions cycle was over that there wasn't room for me on the grant after all and could I please make up the difference? I refused, of course, and fortunately my second choice made a schedule exception for me. That worked fine for a while, and then they straight up altered the deal to the tune of $20,000 in my second year. I hit the "eject" button on Academia and didn't look back.

The institutions involved were Harvard, Cambridge, and Carnegie Mellon, so this isn't a matter of getting caught on a sinking ship. They do it because they can.
This has been my experience as well, at least with my TCLs. Never had a crash despite using Netflix, Disney+ and YouTube.
That's because society, the courts, etc believe people are guilty before it is proven. And "reasonable" doubt is basically whatever they say it is, which is often unreasonable.

Innocent until proven guilty is a cruel joke.

Collaborating with a computer requires a weird kind of empathy, too.

I've often observed that the best programmers are excellent at giving directions to people: anticipating places where confusion might occur, simplifying language, choosing slightly longer but easier to understand routes, and so on. There seems to be overlap between understanding the failure modes of a human following your instructions and understanding the failure modes of a computer following your instructions.

The machine takes you completely literally: if you tell it to delete the production database, it will. It will not stop to ask you, "uh, do you think that's a good idea?", unless you've told it to do that too. It has no common sense on its own. And yet, because it is natural for humans to do so, programmers anthropomorphize the machine.

So programmers empathize (if you will) with our machine collaborators, which is similar in a way to empathizing with users. But anthropomorphized computers and actual human users aren't the same, and eliding them brings sorrow.
You could sell your item in a shady alley for money/drugs instead of through the developers marketplace for their in-game currency.
Here in Europe the turbodiesels seem to be more popular as an alternative. But it's still pretty hard to get them approved. And I believe they require a full replacement instead of a rebuild every few years.

I think it's highly preferable because many airports don't really want to be selling avgas anymore, and this will only become more of a problem as it's phased out. There's also a huge price difference.
Maybe it’s more efficient if you use all the grass for grazing in summer then buy hay in winter, vs letting some grass grow to use for hay later?

This occurred to many people some time ago and subsequently it's been shown that while this is surely a factor in some instances it is not true in the main. Biological differences probabilistically motivate preferences.
I hear you, but you're conflating two things and drawing an overly reductive conclusion:

> if you want to climb the corporate hierarchy it doesn't matter you just need empathy for your boss, so you will get nothing for getting upset when your manager and your peers sacrifice user experience for no reason.

The second half of this sentence is true for any concern not just UX: if you get emotional about your manager and peers doing [anything they consistently do as a group] under the assumption they are doing it for no reason then you have already failed to understand the culture and marginalized yourself and your growth opportunities in that environment.

The first half is a false conclusion born out of the bitterness of passion tempered by misunderstanding. It may be true that in some nepotistic hierarchies that empathy for your boss would be sufficient, but as an engineer who has made a successful career by caring deeply about UX I can assure you it's no way to live. In healthy corporate cultures promotion to higher levels depends more on broad cross-functional empathy and the ability to collaborate and have good judgement with limited depth of information.
If you don't like me repeating your words to you, maybe you should look in a mirror and slap yourself?

Much as I think there's a lot of quackery going on here, I think it's pretty clear that the dog handler is the one giving the evidence and being subject to cross-examination. The dog is just a tool that is being used to achieve an investigative purpose, like a DNA test or radar gun.
Self-driving vehicles will do nothing to change the world.

They will instead further entrench the automobile as the default mode of transportation and we'll continue to have human-hostile cities that are focused at getting people from point A to point B with an automobile. The result will be big driveways that are optimized for big metal boxes with only one person sitting in them, cutting apart communities, making life dangerous for kids and elderly, taking away space that could be better used for trees and boulevards and maybe some kind of mass transport.

Instead we should have cities that are focused on being livable, friendly places that encourage the emergence of communities and foster supportive societies.
We have a bucket of sand to throw it in. Local policy is not to throw it back in the tank for the risk of introducing contamination from the jar.
I don't get the purpose of this comment. Yes, it's great that we have IEEE floats standardised across architectures. And yes, it's also true that IEEE floats have serious flaws and that in the intervening decades vastly superior alternatives have been proposed. How are these two assertions incompatible? Are we supposed to be forever thankful for the political and standardisation feat that we never again attempt to improve on a flawed design?
This is an academic question, if not FUD.

If mainland China launches a military invasion of Taiwan (key word being 'if'):

First, they will have made sure that they have a massive advantage over Taiwan so that victory is virtually certain (as far as these things can be). That's because this will require an operation on the scale of D-day, if not bigger (they will need an air campaign to obtain air supremacy first), and because defeat would be too big a cost both internationally and domestically for the PRC and CPC.

Second, and more to the point, the US will not attack China. They will provide all the support they can to Taiwan in terms of weapons, intelligence, etc. but despite the spin will not send troops to engage the PLA directly.

The US are extremely careful not to commit to any direct involvement for the clear reason they they don't want to and won't because that would mean WWIII for no vital reason, at the very least the possibility to lose by conventional means. A war against China is not winnable on any acceptable terms so the US, like everyone else, will not entertain the possibility unless cornered, for instance if China decided to invade the US (obviously not going to happen).
