They just cancelled a train from Amsterdam to Munich for me and never replied to my form for a refund. I called them about. Had to spend 600 extra for a sleeper instead.

IMHO you can remove the "good" and "except when". DB is 30% of the time a frustrating experience, which I've noticed makes me want to avoid it, even though I love trains. Trai…

Very cool, this is the first language I've seen that has effects/permissions annotated. When reasoning about a bit of code, types and effects are two things that help me grok it. However, th…

Super happy user here! It's an excellent piece of engineering. We're running a fork that supports a "sidecar" server for running multiple integration tests against. So if any tests…

I'm showing this page to my team and investors every couple of weeks. Visual, animated explanations are MUCH better than textual content for deeply grokking something. This is what we're try…

I've been thinking that there might not be new programming languages. The amount of code in the current popular ones will explode, so that's what all LLMs will be trained on. Good luck comin…

I was at a conference in Frankfurt, traveling back to Amsterdam with my cofounder and got stuck in Oberhausen. We have an early flight tomorrow and there's no trains in NL due to a strike tomorro…

we do a very comprehensive scan in multiple dimensions: git blame history, llm passes over every file and a tree-sitter analysis for cognitive complexity. We bring our opinionated approach for tools (…

Ugh same. I had a 49g and a 49g+ in high school. The 49g broke down and the other got robbed when my student room got burgled a couple years later. Learned a lot of RPN programming on those things! I …

My dad's GP didn't know about this, and despite my dad saying "it's fine, I'm taking creatine", sent him for a kidney check-up. Then they found an unrelated tumor on the …

Just as a thought experiment, what would be worse for humanity. Global warming or global cooling by the same amount of degrees C? I'm in western Europe and really hope the AMOC will not collapse.…
