Kerbal Space Program didn't! I wonder if it'd be much harder to simulate real gravity "spheres", with Lagrange points and all. But even without it, in simplified mechanics, planning slingshots and using Oberth effect had been fun.

postgres is sane and consistent. Some things could seem weird, but those usually track to SQL standards, which are weird and dated, but at least consistency is still there. On the other hand, I never can be sure where mysql/mariadb decided to improve my life.

Make a db replica or just a db user account with readonly permissions, and have only those in your env, or docs accessible to agent. It's liberating.

it has learned narratives though, and we talk about AI going rogue all the time.

one day we'll find out they have only one QA person on the team which develops keyboard among other things, and they have comically alien fingers.

AFAIR you can just git clone ../path/to/other/local/repo/.git and it'll use hardlinks, so, basically a copy on write

previously cmd+enter would work to "show in finder". New siri-enabled search seem to break that for some reason, but right click menu/show in finder on a found item still works.

and some rotation probably inevitable anyway, and non-rotating black holes could be just a mathematical construct, no?

recovery features? how do they work? and what smalltalk runtime do you have in mind? I still have a very vague understanding on how changes could be applied to a production running images, or if there is one and preferable way to do that.

New comment by codesnik in "The iPhone Upgrade Program is being replaced by Apple Upgrade"

codesnik — Tue, 28 Jul 2026 22:52:04 +0000

I wonder what apple will do with returned devices. Are they actually refurbishable, on average, to a condition that's resellable, or will they go straight to recycling just to keep numbers of new sales up?

derailing further, it's no organized political movement, and they don't call it immoral but in Caucasus region some men avoid using seat belts as "unmanly", and that's a very social thing. Small plugs into a seatbelt socket to shut up the car audible warning are very common, including taxis.

codesnik — Mon, 20 Jul 2026 10:26:18 +0000

Nice. When I saw some javascript live music arrangement experiments, I thought that forth is syntactically better for that task because of postfix notation - no need to select and execute parts, keywords could be self-adding/playing.

huh. I wonder if it's possible to use those hooks to add syntax highlighting to shell commands claude issues, or to replace full path to current directory with ./

New comment by codesnik in "LuaJIT 3.0 proposed syntax extensions"

codesnik — Thu, 25 Jun 2026 10:45:10 +0000

yes, ruby inherited this from perl, though 'or' has lower precedence than 'and' in perl, and they're equal in ruby. Which sounds like something going to cause mistakes, but I yet to see 'and' and 'or' together in the same expression in ruby.

New comment by codesnik in "Show HN: Oak – Git alternative designed for agents"

codesnik — Tue, 23 Jun 2026 05:07:42 +0000

yep. claude keeps "habitually" trying to use `rg -rn` instead of `rg -n` because it was instructed to use "rg" instead of "grep" by Anthropic, but uses arguments for grep: `grep -rn`. My instructions and "memory" are not helping. "Oh, I did it again, and you've instructed me not to". Older tools are better for current "agents".
