Unfortunately, because the number of imports is restricted the cars will likely be about as expensive as the competition. Chinese car companies have no strong incentive to undercut the market when they can take a fat margin and still sell out anyway.

That reminds me of "Real Life Tron on an Apple IIgs". There's something so charming about system memory being misinterpreted.

No, unless the terminals being "stupid" is the issue.

Why do you want them to take your order if you have access to a terminal?

Is this even correct? It was a two-sided disk, and each side was 174 KB.

This shifted the race of trainees, but it doesn't seem to have changed the more important metric of how many people were actually hired. The author claims it had an effect, but as far as I can tell he's never quantified it.

The real issue is just insufficient slots.

A more whimsical method is to put the thing in a glass of water with the cord sticking out. :-)

HN has some peculiar medical fixations. It comes in waves. For a while there were a lot of submissions about intermittent fasting. 15 years ago people were excited about polyphasic sleep. 10 years ago it was all about modafinil. Enthusiasm about ketamine for depression was big, but it seems to have finally fizzled out.

Can you change the title? It's far more inflammatory than the content, and people here are reacting solely to it.

People keep claiming this, but my experience is that it's pretty similar. My mom's PC accidentally had only 4GB of RAM for the past 5 years (whoops), and we only noticed it a month ago because the cheap SSD was finally dying due to heavy swapping.

As I understand it, DDR5's on-die ECC is mostly a cost-saving measure. Rather than fab perfect DRAM that never flips a bit in normal operation (expensive, lower yield), you can fab imperfect DRAM that is expected to sometimes flip, but then use internal ECC to silently correct it. The end result to the user is theoretically the same.

Because you can't track on-die ECC errors, you have no way of knowing how "faulty" a particular DRAM chip is. And if there's an uncorrected error, you can't detect it.

As I understand it, the big challenge with brain electrodes is that because they are implanted in a big jiggly piece of jelly, they shift out of position and/or cause localized scarring. The practical effect is that the brain-electrode interface "wears out" after a while, and you can't get useful data. Has this been solved, or are implants still temporary?

It's easy to misread, but they're not arguing that. Note the "eventually" and "but right now".

Regarding Semantle, I found that Pimantle (https://semantle.pimanrul.es/) is a much more satisfying implementation to actually play. It provides a 2D visualization of guesses, which lets you see the clusters and lines of similarity more clearly.

Hmm, what's this one?

  var h = hash(guess);
  if (h==7182294905658010 || h==6344346315172974) { return "Adorable guess, but it's spelled “rosy”."; }

I'm guessing they're hashes for " rosie" or " rosey", but what?

Are you sure your browser isn't unloading tabs to save memory? I think Chrome enabled automatic unloading a while ago, and it's been standard on mobile browsers for ages.

Ironically, one of the reason Google's offerings are (were?) worse is because Google prioritized privacy and required pings from multiple phones to count a tracker as seen.
