OP here -- yes indeed. I ever do a new series of posts on upgrading my network to anything faster, the first one will probably be titled something like "25Gb/s Ethernet: how much it costs to rip out your CAT-6A and replace it with fibre".

OP here -- yes, 100%! Within my study it's DACs all the way. I only use 10GBASE-T where it's the only option: through the wall cabling, and from the connector on my ISP's crappy router to the mini-PC that acts as the real router.

Thanks for making the comment! It saved me having to bolt a USB fan over the old, misbehaving SFP+ module or something similarly silly...

Doesn't say anything about citizenship though. There are plenty of US residents who are not citizens. And a lot of people abroad appear to use US billing address credit cards -- in my last company we had hundreds of people with the same US billing address who appeared to be managing Africa-focused businesses and used IPs that matched that.

New comment by gpjt in "Ask HN: High school student – is learning programming still worthwhile?"

gpjt — Fri, 05 Jun 2026 14:24:26 +0000

Excellent points. It's also worth noting that many people don't wind up working in the field they studied at university. CS grads have probably been the exception in recent years, because the industry has been booming, but the two most successful entrepreneurs I know studied philosophy and art history. A friend who is very senior in recruitment studied economics.

That is an excellent point so long as you don't take it too far! Lisp/Haskell/Erlang yes. INTERCAL/Brainfuck less so...

New comment by gpjt in "Scientists say they've reversed brain aging in mice with a nasal spray"

gpjt — Wed, 27 May 2026 17:20:57 +0000

Hmmm. "Comforting haze" seems dubious. My grandmother had Alzheimer's and at least from the outside it seemed like a bad LSD trip that never ended. She didn't understand what was happening and was scared.

Sample size of one and anecdotal of course, but...

I was thinking the same. It's a simple idea, heavily over-explained. The code is similar, massively overengineered for such a simple test.

I guess if it's on the inside of a water-cooling loop, you should be OK if the water is pure enough. I don't know how hard that "enough" would be, though.
