It's officially #MaintainerMonth! To celebrate, I just published psas.dev which has README badges maintainers can use to communicate boundaries for their #opensource projects.

seldo.comNobody pays for open source. We can force them to. | Seldo.comThirty years of voluntary funding schemes haven't paid open source maintainers because asking doesn't scale. The real money already flows — to JFrog, Docker, Sonatype — at the registry layer. The fix: registries charge companies for supply (they already do), then route a slice automatically to the maintainers who make that supply worth having.

Mochi is so precious!

I have been writing this post about the economics of open source, on and off, for 13 years. I wasn't expecting to end up at "Microsoft should send corporations a huge bill" but nothing else we've tried has worked. https://seldo.com/posts/nobody-pays-for-open-source-we-can-force-them-to/

Hash.extract! is my latest fun discovery in Rails' collection of Ruby extensions. It returns a new hash of the keys you name, while simultaneously removing those keys from the original hash. It's also safe to use when the named key doesn't appear in the original hash.

api.rubyonrails.orgHashBuilds a Hash from XML just like Hash.from_xml, but also allows Symbol and YAML.

Joseph Hale@thehale.dev

Looks like #Python 3.15 will include a built-in, immutable `frozendict` type. "Using an immutable mapping as a function parameter’s default value avoids the problem of mutable default values." There are other benefits too (e.g. `frozendict`s are hashable).

DRY code is pretty good. DRY teams, not so much. Open source is just as much about the people it builds up as it is about the projects/code those people then build and share.

when you collaborate in open source teams, you need to unlearn a lot of what your company work taught you

Happy #Epochalypse Day! It's T minus 12 years until the world faces new set of Y2K-type issues. Why?

19 Jan

Many computers track time by counting the number of seconds since January 1, 1970 (the "Epoch"). They count with a signed 32-bit integer, which will last until January 19, 2038 at 03:14:07 UTC. Then, the value will "overflow" and computers will think it is December 13, 1901. 😧

19 Jan

Fortunately, computers are already being updated to use 64-bit integers, which will delay the Epochalypse for approximately 292 billion years 🎉. #NerdyHolidays

"Thank you for existing", "I'm 11 years old and ... your library made it possible" It's amazing how far a single kind gesture can go.

one thing that blew my mind about working in Lean (and is still blowing my mind) is that “variables” (really, let bindings) and “function calls” are all infinitely unfoldable. i can just replace each variable with its definition, each function with its body, any no of levels deep, during a proof.

"Error: Invalid file name. Only characters on the basic multilingual plane are supported." What do you think this error message means? I ran into it recently while #debugging a migration of several hundred thousand documents. Here's what I learned: (1/4)

Notably, the basic plane does not include emojis -- those are in the Supplementary Multilingual Plane. So, the error is effectively saying, "we don't support emojis in filenames". 😭 (3/4)

It turns out that the Basic Multilingual Plane refers to the part of the #Unicode specification which encodes all the most common characters used across the world. It's the first of 17 different planes of characters! (2/4)
