@whitequark Yea, I know :(. There are 10 billion reasons I haven't thought of as to why this is a bad idea. But I can dream, right :'D?

(Actual use case I thought of in 10 seconds was: "someone gives me a PR for a small project, I run e.g. Buildbot/whatever locally to see if it passe. If it doesn't, give them feedback." Doesn't scale of course, but I'm not at GH's mercy.)

@dalias @kevinmehall @regehr Maybe it's a newly* deployed feature on Mastodon dot social? I just pasted the link in and a preview showed up :o...

* Old, and I never thought about it?

@dalias @kevinmehall @regehr Just to avoid rewriting my response:

@whitequark You may find "The Pruitt-Igoe Myth" documentary interesting. It was a commie block in St. Louis in the 50s. TL;DR it failed because racism, _of f***ing course_. The documentary leans more into the "no one _wanted_ it to succeed" angle. But lots of cool footage and interviews.

Maybe UK will have better luck.

@dalias My interpretation is that it's missing the operand- i.e. it parses as ([ (-n) ]). I would expect a parse like ([ (-n ])) to complain about a missing closing ]- and it doesn't.

OTOH, it _feels_ reasonable to me that a ([ (-n) ]) parse could be special cased as ([ (-n) () ])- "I'm testing against nothing/a missing operand. Might as well treat as null". But then again, the actual behavior (fall back to 1 arg "test") is easier to parse: https://mastodon.tmm.cx/@hp/115579846674997395

#lazyweb Is there a historical reason why "[ -n ]; echo $?", written exactly like that in a shell, echos true/0?

#lazyweb Anyone who is familiar w/ ipv6 and OpenWRT help me out?

I can't seem to get my router an ipv6 address, even though the router is assigning DHCPv6 addresses to attached nodes just fine.

Windows leaves the "Default ipv6 Gateway" field blank in "Wi-fi Status", and Luci's landing page does NOT have an "Upstream ipv6" portion. What options can I check from an ssh session to figure out whether it's my fault or my ISPs?

Weird to me that DHCPv6 gave me non-link local addrs anyway...

@alice @dalias Please remember to seed your Linux/BSD ISOs as well :3...

@dalias What does PID 0/init get as its umask?

#lazyweb umask is set system-wide in /etc/profile. If I comment that out, what will be the default umask I get? What is the default umask per process?

Is umask inheritance a shell thing or does every process keep umask state (even if they weren't started from a shell)?

Not modifying my system to try this.

For those curious, this weird CSS seems to work because the exact string "font-family: monospace;" has historically been hardcoded to be treated specially by browsers. "font-family: monospace, [your-family-here]" cancels out the hardcoded behavior (while still using monospace, due to CSS favoring builtins _AIUI_??). Yikes.

> acquired by a new session

If processes can ignore SIGHUP (like nohup), this means it's possible to "transfer" the stdout/stdin/stderr from one terminal to another? Is it possible to transfer streams via ssh disconnect by ignoring SIGHUP (which is pretty much exclusively how I used nohup before I learned about screen/tmux)?

My impression is that SIGHUP _mostly_ causes processes to die. So if I do "nohup foo" in an ssh session, the shell will die on disconnect, and "foo" reparented.

SIGHUP was probably the first signal I was introduced to (because I used nohup to run long-running processes before I learned about screen/tmux), but it's probably the signal I understand the least. Maybe I should change that.

(Wonder if tmux uses it under the hood or does some other magic...)

@lanodan @neil @dalias Fun thing I noticed recently in F-Zero (SNES)... Mute City and White Land have the same city background, just with different palettes :D. It took me _years_ to notice :'D...

@dalias Hi! I found this by chance while looking up fan info... Do you think Noctua fans are bad in general, or just bad for 3d printing? https://3dprinting.stackexchange.com/a/20816

(Current use case... my old laptop's internal fan seems to be showing its age, so I put some 12v PC fans I had lying around next to the outtake. They work well, but I want something less bulky, noisy, and not 12V so I can power them via USB w/o using a boost converter. I like Noctua, but I found your reply here lol.)

@dalias > Is this an honest shitpost or a troll?

I don't know actually. The subtext is: "I think it's great we critique (putting it mildly) AI as a way to abdicate ourselves from caring about the lower levels. I wish we were more considerate like that with lots of other software tools we used, and I'm picking on compilers b/c I'm bitter that I could spend the rest of my life trying to understand all of e.g. LLVM/GCC but I physically couldn't/can't."

@dalias To be clear, I think Servo accepting AI contributions is a bad idea and the slippery slope ("it's only minor contributions") is not a fallacy here.

The increase in contributors is likely not going to be from a pool of people who care about their work or want to understand what's going on. I've seen the drive-by AI PRs for ppl looking to pad their GH with contributions.

What makes compilers different from AI? They're both abstracting away the need to understand what's going on; even further than the lies macroarch (via microarch), and transistor models (via quantum mechanics) are already telling you.
