What we found
A security talk on why human oversight cannot reliably catch LLM mistakes.
Source discussion: Don't be a meat proxy
“Great security talk about how humans aren't setup to deal with LLMs as tools. I love the bullet point(s) : we don't trust [aircraft] pilots to catch automations mistakes (e.g. autopilot), but we are expecting humans to catch LLM mistakes.”

Jane Street's OCaml library for dense, interactive web and terminal interfaces.
Source discussion: Bonsai: Janestreet's UI Library
“This is great. It focuses on utility and information density over design. It looks like someone took a terminal UI and transplanted it to the web, Bloomberg terminal style. I'm pretty sure you can build tools with this that are fast and pleasant to use.”

Source discussion: What DMARC Protects You From, and What It Does Not
“I use rspamd. This might be a little heavy if you’re solely looking for DMARC validation, but I use the other parts of rspamd as well for inbound email.”

A mature communications toolkit with inline file transfer over SSH sessions.
Source discussion: Celebrating 45 Years of Kermit with the First New C-Kermit Release in 15 Years
“One cool feature is that you can use C-Kermit to do inline file transfers over the open SSH session. It doesn't work over a terminal muxer like screen/tmux, but it is pretty useful for a quick way to transfer files between the client and the remote host.”

An Italian anchovy fish sauce used to add concentrated umami to dishes.
Source discussion: Decades-old fish sauce at abandoned factory in Canada finally being removed
“Despite the fearsome smell when it’s collected together in bulk, modern garum in the form of Colatura di Alici is a genuinely magical ingredient. It’s very similar to what the Romans used, except it’s made exclusively from anchovies whereas the Romans used many varieties of fish to make garum. I use it often in pasta dishes especially, but it’s a versatile ingredient for adding umami in general.”
