I stopped reading their privacy policy at "Fastmail is an Australian company" - Australia is a five eyes jurisdiction. That said, I'm a happy customer of almost a decade with them, but my email correspondence is pretty boring and not politically sensitive.

If you liked 3B1B and prefer intuition/applications-heavy view, then definitely Strang over Axler. Check out especially his newer textbook "Linear Algebra and Learning from Data".

Axler is more of a pure math textbook - if you want to dive more into proofs and abstractions.

ivankra — Sun, 19 Jul 2026 05:06:18 +0000

This is more about lp(a) type of cholesterol which is largely driven by genetics, and barely responds to lifestyle/diet.

lp(a) is not part of routine blood tests - you probably didn't measure it unless you specifically asked for it.

No, that's been mainly due to RLVR.

Pretty sure they did it to themselves with terrible policies and moderation. AI was merely the final nail in the coffin.

Interesting to compare with MathOverflow which has distinctly different policies (only research-level questions) and professional community: https://data.stackexchange.com/mathoverflow/query/1953768/st... - also falling lately, but by a factor of 2-3x from peak rather than 1000x.

That's well in the past. It's at the bottom in the EU by GDP growth now, and little hope for a come back.

I had no problems subscribing to stuff through wise or revolut cards. Both are prepaid as far as I'm concerned - they won't let me spend above my account's balance.

> Do you realise that China is a downgrade in life quality wise?

For whom?? Maybe for the filthy rich, but certainly not the average citizen. You earn way more money in the US, but for life quality (unless dollars is all that matters to you) between them even I'd pick China. Come visit it once, don't get fooled by online echo chambers.

Happening already. My new claude max account got instabanned after just a few messages asking it to debug some stuff for me, that they felt like a TOS violation. Nothing remotely controversial. The main model didn't even complain, some dumber background censorship model flagged it.

Lucky you. My new claude max account simply got instabanned. All I asked it was to build node and V8 "to investigate some node crashes" (the part I think it overindexed on) and look into a few diffs. And bam, "An internal investigation of suspicious signals associated with your account indicates a violation of our Usage Policy. As a result, we have revoked your access to Claude"

They are even worse than Google, which at least doesn't ban your whole account if you search the wrong thing.

$250/hr if you tell me how to do my job

You can prompt an LLM to generate tests from the spec and I'd bet it would easily get most of the way there, especially if you give it a reference implementation to test against. I did just that, though on a small scale - just for feature tests. The last few percent would be the real challenge, you probably don't want it to just imitate another implementation's bugs.
