Well this is massive: - Every non-US company sees how they can be cut off from US vendors with a snap of a finger. Non-US vendors getting free advertisement - What does this mean for US AI labs’ offices and employees outside the US? Reads pretty draconian What a mess

Supply chain attacks are becoming more frequent, and far more serious. What are sensible practices to protect against these when using Node or Python packages? I assume pinning versions is the bare minimum; for those with security teams / tools: why else do you do / can you do?

Amusing how 99% of people using LLMs forget how these things work: They are advanced probability machines. They generate the next most likely token (word) based in the input and their training. Under the hood, it’s a giant matrix multiplication that has eerily good output.

SO frustrating when (at a larger company) you need another service make a small change... so you ask the team owning it to do it, and they tell you "sorry, can't do now, we can do it maybe in 2-3 months" SO liberating when you can just make the change yourself and submit the PR
