mawk's fflush() doesn't do what you think it might or what the gawk docs say (which is what the AI's are trained on). -Keith (two hours later)

spent 3 hours debugging our logging system. Down all types of rabbit holes including questioning my understanding of how `nohup` works. Nope: `mawk` was installed rather than `gawk` for a little `awk` timestamp pipe. Sofware, man. (AI didn't help either because all the slurped docs are gawk.)

Just helping with editing here. These bots aren’t sentient. They’re doing what they’re programmed to do. OpenAI, a private company supposedly bound by laws, committed federal crimes.

that's my jam
a shell pipeline in a terminal compiling a regex, where the regex was written with syntax that would be pathological when executed backtracking style. stages of the pipeline show:
1. constructing an NFA from the regex (it goes through an AST first of course, but we don't see that). the NFA here contains loops within loops, where the exit from the loop is ambiguous: given an input of 'b' we could be iterating around an inner or an outer loop, but we don't know which until there's a following character 'a' or not.
2. NFA -> minimal DFA. this is where the ambiguity is resolved, and every state has outgoing edges that are deterministic
3. the same DFA output to a text format
4. the text format piped into the same tool, a command line interface for libfsm, showing a constructed AST
5. the AST rendered out to pcre regex syntax. the end result here now contains just one loop, with the contents rearranged such that it wouldn't be pathological given a backtracking implementation

I think another lesson to take from the loss of both Dolly and Tim Curry is that neither of them took themselves seriously but they took the work dead serious that's the most important thing pour all of yourself into the craft but have fun and don't get an ego.

Adopting a cautiously optimistic perspective on AI, the literary critic and editor Martin Puchner proposes that we share something fundamental with the machines: the use of language. To explore this, he draws on a rich tapestry of theory, literature and life experience in this Essay

Strong resistance to AI among writers is understandable. But it obscures what we share with the machines: language itself

God is sending a message.⚡️ #UFCFreedom250
Tweet from the Weather Channel: “UFC Freedom 250 is facing a chaotic weather setup on the White House South Lawn, with a 60% chance of thunderstorms, heavy downpours, and wind gusts up to 34 mph threatening to delay the outdoor fights. On top of the storm risk, brutal D.C. humidity is driving a triple-digit heat index alongside massive swarms of mosquitos and gnats that fighters will have to battle inside the cage. While the venue’s massive 92-foot overhang will keep the octagon dry, a single lightning strike within eight miles will trigger an automatic 30-minute freeze on the entire event.”

This is really what I want people to appreciate. I get that it feels good to be like "well that person's a pedophile too!" But in many cases they weren't. They were just people who didn't think it was a big deal. That's terrible in its own particular way.
