Joke of the day from Moscow: Russia tried to unveil its first humanoid AI robot, Aidol. Key word: tried. The robot collapsed during its debut, forcing organizers to cut the presentation short. Their rushed attempt to lift the prop only made things worse.

It's wild how instead of "is it Elm the mail client?" the HN comments focused on "is it BEAM the Apache Beam?"
Never change.

@antirez.bsky.social's C course is the first time I'm seeing YouTube auto-dubbing: www.youtube.com/watch?v=-1Zh...
I'm not sure how I feel about it, but it probably is a net positive due to being able to consume that content in English?
Still prefer original audio with English auto-subtitles though

Today I got to 21:45 on my talk practice, while tired and trying very hard to not say any "you know"-like words. I think I might get under 20 minutes tomorrow!

> As a result, Awk is usually good for prototyping, and sometimes it is entirely adequate for production use.
I love the modesty. But also, yeah, I can see it be strong for one-off tasks tailored to your small dataset, not a production thing to handle all edge cases...

I'm enjoying being in the "clueless PM not caring about code quality and not knowing what they want" mode when making a throwaway visualizer for the "Build your own BEAM" talk.
