All LEDs are like this. It's horrible. The only good thing about it is that every professional in the entire industry has come to expect that if it's an LED, something somewhere will be wrong with it.

Why is this posted here? It's old, and it's not terribly relevant, though it's not useless. For anything larger than 2 pins, pin 1 at upper left and pin 1 at lower left are both quite common. Components are also reeled more o

To be fair, sometimes the blinding is a piece of duct tape over the display on a piece of fancy OTS industrial equipment. Though we needed to poke at it occasionally, so we needed a duct tape flap we could lift up every now and then rather

Yes, this, exactly. The moment someone has a theory that's experimentally testable somehow (somehow possible, anyway), there will be plenty of interest. There has never been such a theory to date. Until that arrives, it's all just

You would probably be very surprised about just how much work is put in to characterizing these things. My graduate work was on another experiment (though our postdoc worked on one of the earlier g −2 experiments mentioned here!), but we l

Celebrating the mistakes is, as you're saying, perhaps a bit too far. But mistakes will happen, it's just the nature of the world. That makes developing a robust error correction mentality something that genuinely is worth celeb

The V5 is a great pen! They used to be my daily driver, and if you want what they do well, they're hard to beat. (Fountain pens can and will, but they're fussy, and everyone knows it. They're basically V5s on steroids: same h

I think there absolutely are 10x doctors! When every doctor or specialist you meet in a field says "yeah, Dr X is a massive asshole and I kind of hate him personally but if I ever need [not-particularly-rare procedure Y], I want him to

The G2 definitely does glob. That's one of its bigger faults. (Others being that I, personally, prefer a line width between the 05 and 07 options -- obviously this is world-stoppingly critically important -- and that really old ones,

If you love the V5, then the next step is definitely a fountain pen. There are plenty of guides out there, so I'll not waste time doing an inferior job of making a specific recommendation.

The modern version of this is the Pilot G2. Scatter 'em around everywhere! 80% as good as fountain pens at 1% of the fussiness. I have a Lamy 2000 (well, more than one...) that I adore for writing anything with any actual length. But I

Would anyone downvoting care to explain? I'm genuinely interested in seeing anything that suggests there's either some secret breakthrough (completely plausible, but there's no evidence that I've seen hint of) making qua

Agreed. This looks from the outside like someone read a report, got unnecessarily spooked, and now the rest of the herd is following along. But it's also very possible that hypothetical report was genuinely concerning. We just haven&#x

The word "uncorrelated" is doing a lot of heavy lifting in that claim. Most DRAM error sources are pretty clearly correlated, if you're paying any attention.

FYI, it's not so much photons (gamma rays) as muons. Muons are nasty little buggers.

We're right here! Some of us just prefer to stay out of these silly irrational debates because we know that neither of those two crazy camps will listen to a word we, or anyone else, will say. We might be wrong about that (I hope we&#x

I don't have anything covering recent generations. Try the usual suspects, I guess (Agner Fog et al). Sorry that's not more useful, but I haven't seriously worked on x86 in over a decade, so I'm a bit out of date. Certai

by exmadscientist 2mo ago
A huge part of the problem here is that you're playing with the 8-bit registers. They work , but they're like travelling the back roads: the CPU designers put all their effort into the big highway next door, and not so much into

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 change this calculus

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

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 out wh

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 defendants.

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, perhaps a different

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 say

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 S
