Part of my point is that making a print head driver is, in general, harder than making a laser imaging head. A lot harder. Of course the details of what specific parts are purchaseable on the open market can and will…
I talked a bit about this years ago: https://news.ycombinator.com/item?id=37007815 TL;DR: I'm surprised this isn't a laser printer, as those are actually quite a bit easier to design and manufacture, especially if you…
Exactly! Quantum mechanics is an excellent example here. It is not "defeatist" to accept that we don't know where the electron in the hydrogen atom actually is. Or to accept that if we really, really wanted to figure…
> optimistic that modern reactor designs and reprocessing technologies can overcome these issues The obstacles aren't technical. They never really have been. The obstacles are human: political, bureaucratic, and…
And following on from that, this has all the hallmarks of a successful appeal for unreasonable sentences. However, it's going to go to the Fifth Circuit, who are, ah, not known for their friendliness to criminal…
> There is always one "The Diagnosis". No, that is not true at all. This is a kind of thinking a lot of programmers fall prey to. The real world, outside of code, is a very fuzzy and inherently analog place. There is…
Somehow I only managed to end up on one of these gorgeous birds once. In seat 64K, NRT-DTW (or was it NRT-MSP?). The main cabin is... nothing to write home about. I was in no hurry to book another 744 leg. Upper deck,…
Not really. They're trying to split up potential causes of failure between: 1. "Funding" meaning: We knew what we had to do but didn't have enough money to do it; if we had, this path would have worked (though why it…
Right -- if you're invested in the NASDAQ 100 (most people aren't, directly or indirectly), get angry. Or get out, if you can and it's not too late. Everyone else has dodged this bullet. I'm surprised, pleasantly, that…
> I will never understand why so many otherwise smart people keep trying to make nuclear happen in their minds. I don't really get this either. I've come to think that it comes down to two pieces. The easy piece is that…
Or, to say a little more explicitly what you're getting at: when you take a logarithm of some quantity, log x, x absolutely must be unitless. There's no way whatsoever to take a logarithm of something with a unit…
Robots that cannot share sidewalks with humans, including humans in wheelchairs, should be banned from sidewalks. Full stop. End of discussion. They can use the streets proper if they want to. I'm sure there is some way…
The article is making the case that this is not healthy for society. It is the kind of thing that's fine if 5/100 do it, seriously worrying if 50/100 do, and basically fatal to civilized society if 99/100 people do. And…
I think that's an unusual scenario, and I'd ask you to consider that that's probably not the argument I was making. Most of the dozens and dozens of people I see in daily life sealed away in their earbud pockets do not…
Being able to do it in the middle of a riot is, absolutely, a hard-earned skill. But it is, like so many of these things, a skill. You have to practice it. I think that putting earbuds in and checking out of the world…
Talking to strangers is a skill. You can practice it! I've made a point of trying to practice, albeit halfheartedly, and even though it's difficult for me, because I like it when other people try to talk to me. Earbuds…
The actual "make it go bang" bit here isn't the most potent. (I think I have capacitors here which wouldn't care in the least about this, despite their datasheet ratings.) If you need to take it to the next level,…
The ads showed up when the launcher got a major redesign, and the Google TV (or whatever they call it this week) launcher is a Google product. I seem to remember that nVidia delayed shipping the new enshittified version…
My point, which matches what you've written out in more detail, is that there's supposed to be stuff (resistors) in the cable, stuff which is often not there. There are plenty of these abhorrent cables in the wild. And…
The 4.7k "default pullup" is an old-school 5V TTL thing. It works really well for TTL inputs. But CMOS inputs don't really care very much, especially if they aren't toggling or if there's a bit of hysteresis on the…
The controlling standard is usually 62368, and the target is usually being a "Limited Power Source", which is 60V or less, and 100 VA max.
Right. That phrase "standards-compliant" in the above comments is doing a lot of heavy lifting. A lot of devices are not actually standards-compliant. Some are close. (This may actually be worse.) My experience has been…
I was speaking a little more towards the AliExpress end of things, which is a sadly high proportion of the devices out there. For the midsize CMs and up, you're right, they've got piles and piles of stuff and don't…
How is it an overcorrection to describe their actual behavior? They're still an important part of the protection hierarchy. Nothing else does what a good fuse or circuit breaker does. You just can't count on them to do…
That's how it's supposed to work, yeah. But there is some trash out there in the world. A lot of it, actually. Some naughty cables work with some naughty chargers work with some naughty devices. Postel's Law in action,…
