Yes, it makes sense that `uv lock` commands only work the lock file, but users have real needs to upgrade direct and transitive dependencies. For transitive dependencies `uv lock --upgrade-package` works, even if a bit wordy. For direct dependencies, `uv lock --upgrade-package` also works, but doesn't touch `pyproject.toml`, which is much more developer visible. As `uv.lock` package versions get ahead of `pyproject.toml`, `pyproject.toml` becomes a less dependable guide to the surface area of dependencies. A friendly `uv upgrade` command would be nice.

The biggest uv ux footgun I have seen by far is `uv pip`. I have seen a lot of projects use uv correctly with pyproject.toml/uv.lock for development, but then use `uv pip install -r pyproject.toml`, which bypasses uv.lock, in their deployment Dockerfiles and ci tooling. Yes, coding agents are to blame for recommending bad `uv pip` patterns because they have so much `pip` in their training sets, but uv should provide some affordances to protect the user.

Sorry for the rant, uv is a great tool, that I think[0] should be used more! Thank you for your contributions to the ecosystem.

And speaking of agents writing tests, I have an ask. The tests agents love to write are in a lot of ways like human written tests, perfunctory and smelly. They are there to check coverage or prompt checkbox, but they barely stress the system under test. I often find that the tests are faking and mocking so many inputs, methods, and side effects, that they aren't testing anything at all. Asking the agent to write the tests first so that they the underlying implementation is more testable has yielded no results.

What has worked for people to get agents to write more testable implementations and better tests?

PS. Reacting to Uncle Bob, I found metric driven agentic refactors just push complexity to outside the scope of the metric. I am finding I need to actively guide the agents for the refactors to actually improve things without increasing the entropy of the codebase.

1) 2008: pip, 2012: Conda, 2018: Poetry, 2021: PDM, 2023: Rye, 2024: uv. A new package manager every few years rather than every few months would be more apt. But, yes I agree we shouldn't tool churn for newness sake.

2) Have you tried uv? The speed is nice, but is not what makes it shine.

3) uv not being written in python is a defining positive feature for it. It eliminates the bootstrap problem of having to get a system python with the right setup before you can run your python manager, virtualenv manager, and finally package manager. I haven't had to debug anyones virtualenv or python version issues in a year.

Consider the Moon as viewed from NYC at time of comment [0], it is hiding below the horizon. If you were to look at my website and then at the sky you might become upset that I am reporting the shape of the moon, but obviously it can't be seen. Hence why the website reports the angle below the horizon roughly half the time it isn't visible.

Adding Azimuth and Elevation when the Moon is above the horizon would be for completionism only and not the real enterprise use-cases served by ANSI compliant renderings of the Moon.

Maybe this is the opportunity to invent and suggest a symbol for Altitude?

Are you planning to release this as a library or a tool, or should we just take the relevant MIT licensed code from your website [4]?

On replicate.com a single image takes 1.5s at a price of 1000 images per $1. Would be interesting to see how quick it is on ComfyUI Cloud.

Overall, running generative models locally on Macs seems very poor time investment.

Dela doesn't currently support mise as a source of tasks, but I will happily implement it if there is demand. Currently [1] I saw mise use on 94 out of 100,000 most starred github repos.

Thank you for allowing this moment of self promotion.

Khrushchyovkas did not have communal kitchens; I grew up in one [0]. Perhaps you are thinking about kommunalkas [1]?

What is the motivation for viewbox coordinates being at (0,0)? I have been thinking about setting chart gutters so that the graph is left aligned with the text, but this seems like an orthogonal issue.

* The charts are never blurry

* The text in the chart is selectable and searchable

* The file size could be small compared to PNGs

* The charts can use a font set by a stylesheet

* The charts can have a builtin dark mode (not demonstrated on my blog)

Additionally as the OP shown, the text in SVG is indexed by google, but comes up in the image sections [1].

The downside was hours of fiddling with system fonts and webfonts and font settings in matplotlib. Also the sizing of the text in the chart and how it is displayed in your page is tightly coupled and requires some forethought.

I wonder why that is? Is it because it is a runtime, and getting compatibility there is harder than just for a straight package manager?

Can someone who tried bun and didn't adopt it personally or at work chime in and say why?

I recommend putting together the Quintet in one image, so that the original 4 charts, plus the new one are all visible and interpretable together. It will be learning aid for decades to come.
