I administrate my home lab using podman desktop and quadlets. It is one of the few GUIs for what is mostly a cli utility that really adds value.

Edit: Sorry for repeating myself. Still thinking out loud. I have already started. Not only is the concat faster (which means the derived operations in the rrb tree will be faster), but the derived operations can be done directly since the

Hmmm. This comment made me think. If you would do a radix tree that degrades to a b+tree, you would get a couple of things. The b+tree concat and subsequently insertions and removal, is faster than the rrb tree one, but yields more relaxed

This is a persistent ordered map on b+trees. https://rikspucko.koketteriet.se/bjoli/PersistentMap/src/bra...

that is because many implementations bypass strict rebalancing to squeeze out extra concat performance. And because the strict rebalancing algorithm is awful to implement.

you could also compare if (a === b && b === c && c === d && d == e) To scheme's (= a b c d e) JavaScript clearly has the upper hand.

Thanks! I havet always been linking to the Collections subdir so I have missed this dumb issue. Will fix next time I use a computer. Might be some time though. If you have any questions about the trees, feel free to ask.

As I said, i think they have been teaching long enough to have a pretty good basis for the claim that racket's syntax can be a problem. I am firmly in the "after a while you don't see the parentheses" camp, but I have a

Finally someone uses the rrb tree as their main data structure! I implemented it for c# and the performance tradeoff compared to List<> was smaller than i had thought. https://github.com/bjoli/RrbList/tree&#x

A lot of people hate sexprs. Even seemingly reasonable folks. I imagined they have met students that really struggle with the syntax, while grokking the concepts easily. I myself have heard "the parentheses are hard to balance" an

It is hidden by default and when you mouse over it it is so bland that it is hard to see where you are on the page. I havent used Mac is in a while, so I am not sure about how it is today, but this seems to have been the development everywh

Luis Alvarez is really a fascinating character. The whole pyramid thing is not mentioned in the article, but it is also fantastic thing to read about if you are curious about Alvarez.

What has been going on with deepseek recently? I have gotten lots of replies in Chinese and even more frequently, reasoning in Chinese as well. Is it a new silent update?

A statically typed s-expression language for dotnet (called bjolang. Because I made it), with fast Rrb vectors and champ maps. No object system, but a trait system with associated types. The looping system is inspired by my own hygienic loo

To continue on this: info use systemd on most of my systems. I dont mind. But despite having used it for about 14 years, I still have to read the manual of journalctl. Systemctl is OK, but I really do not like that respect of the utilities.

Does anyone know if there is any progress on window shading on Wayland? I miss it like crazy.

I hard disagree. Previously I could use what I knew about Linux commands to read logs and administer the systemm. Systemctl knowledge does not generalize. I have done scheme all my life, which is why I prefer shepherd. Not only is it in a s

I also went fedora-based and installed kinoite and then rebased on Aurora. I am extremely happy. I fell in love with Immutable linux with aeon, but I had so many weird issues with gnome that I ended up having to switch back to KDE. I dislik

I think it is much more obvious than being able to return from anywhere in a function. If the last expression is a match, I know every match body must return the same type. if the last is a (cond ...) I know ever cond branch must return a

Try using them for cross words in a small manguage. It is hillarilus. Now, it has gotten better, but even top end models frequently answer confidently with things like "'eats grass and farts, 3 letters, _o_' , must be ozelot!

Having all numbers be valid in only one way is a great idea. So much that I believe webassembly enforced canonical leb128, at the cost of decoding speed. And say you have it as part of some other data. If you want to be able to hash it by t

I remember a violin player back in my youth Orchestra days who always wanted to sleep in the same room as woodwond players (3 people in every room) because "string players snore".

Using delimited continuations in a web framework is magic. In remember the first time I saw things like pharo and wodered how it was even possible. Doing that stuff in Python is still hard. Doing it in racket is easy peasy.

It is just a runtime, no? I have only ever heard about it as something to run their own bend programming language. Are people targeting it as a runtime for Haskell as well?

I let it loose on a f# codebase that I know was pretty optimized but with a few low hanging fruit changes that would have a big impact. 3.1 Pro did NOT find them. 3.5 flash did. Plus one I hadn't thought of that may or may not work (wh

I think it is a lovely experience just because it forces you to think about which abstractions are the correct ones. I think many people have had the feeling that they would love to change one (or many) aspects of a programming language. I

I folllowed him on YouTube for a while until he presented one of those new meta analysis on cholesterol (half a year ago maybe?) studies in a way that was highly uncritical. He forgot to mention that the meta analysis mentioned the Minneso
