I really appreciated his coding-style, but the bar is quite low on research/ML-algorithms to be fair. I still wonder how he managed to get „trending“ repositories regularly despite the repositories being empty.

What was happening with this account? I was often seeing popular but empty (only title of the paper and maybe a short readme) repositories that were created directly after a paper was published?

Do you have a link to share? Would be highly interested!

I would say uv provides quite a lot of additional features that can be used in various ways to create plain-old venvs. Note, however that uv-pack can also pack a subset of your uv-monorepo for a specific package (there are still some quirks I have to admit..).

My experience was that it‘s surprisingly painful to „just copy“ a venv and especially a uv-created venv. There are a lot of paths to be modified to get the venv working. Copying a venv felt hacky and wrong, that‘s why I built the tool :)

I kept running into the same problem: modern Python tooling, but deployments to air-gapped systems are a pain. Even with uv, moving a fully locked environment into a network-isolated machine was no fun.

uv-pack should make this task less frustrating. It bundles a locked uv environment into a single directory that installs fully offline—dependencies, local packages, and optionally a portable Python interpreter. Copy it over, run one script, and you get the exact same environment every time.

Just released, would love some feedback!

I am using runtime type and shape checking and wrote a tiny library to merge both into a single typecheck decorator [1]. It‘s not perfect, but I haven‘t found a better approach yet.

There appears to be (almost) no true competition in healthcare, therefore no real incentives to improve productivity. Wages in healthcare rise disproportionately without productivity gains (Baumols disease); why invest in digitalization?

> The key insight is that smaller, well-bounded changes are exponentially easier to review thoroughly.

I am not sure if that is the real insight. It appears to me that most people prefer small, well-bounded changes, but it's quite tricky to break down large tasks into small but meaningful changes, isn't it? To me, that appears to be the key.

Working in the ML field, I can't hate Python. But the type system (pre-3.12, of course) cost me a lot of nerves. Hoping for a better post-3.12 experience once all libraries are usable in 3.12+. After that experience, I’ve come to truly appreciate TypeScript’s type system. Never thought I’d say that.

That‘s actually quite similar to the nearness library [1]. The main difference appears to be vicinity‘s focus on simplicity while nearness tries to expose most of the functionality of the underlying backends.

That's the point I was trying to make, which is also why I brought up 'pseudo-local' development environments in the article.

There are libraries that support shape checking and I‘ve written a package to combine beartype’s runtime typechecks with jaxtyping‘s shapechecks, see https://github.com/davnn/safecheck

Once accustomed to shape checking it‘s quite a boost in productivity for us, no more fiddling around with invalid dimensions.
