Honestly, I can’t support Y Combinator (by contributing to this site) after the CEO does something like this without repercussions—song lyrics or not.

This is schemescape signing off.

Thanks for the correction! I had only used Lua, and thought Fennel had no runtime, so I assumed this was not possible.

Short answer: I don’t know. That sounds like a good idea, but how would that access local variables in the caller (to inspect state)?

I remember the Lua C API exposes a lot of information, but I didn’t think it was accessible from scripts. Of course, it was a long time ago and I could have easily missed something at the time. Happy to be corrected!

Edit: you might also run into difficulties trying to redefine non-global functions to add the call to “repl”.

Last I checked, Lua was “bring your own debugger”. Assuming that hasn’t changed, a REPL is nice, but you can’t pause and inspect anything by default.

Good list! I, too, have many complaints about Common Lisp.

But for a language whose standard hasn’t been updated in roughly 30 years, it holds up impressively well!

Thanks! Most of those seem like a fair trade-off for portability… for an app.

I’m not sure it’s a great idea for an OS as in the OP, but I do like that they claim accurate incremental rebuilds, to ensure everything get updated. Certainly an interesting experiment!

Edit: just to clarify, I meant "app" as in "something that isn't part of the OS/distribution".

What are the quirks of static linking you need to work around (in general, not for glibc)?

Does anyone know how big the base installation is? I couldn't find an answer anywhere, and the link to the QEMU image appears to be broken, currently.

I'm curious how it compares to, say, Alpine with a similar set of packages.

Maybe not all pages are reachable from the root.

Do you have any programming language or UI toolkit preference? That will likely scope your options.

If it's just for you, you could use something simple like Tk (e.g. Python + Tkinter).

It sounds like how the pedals react and one-pedal driving are the reasons they suspect? I was expecting touchscreen-only controls to be mentioned, but for all I know new ICE vehicles are like that too.

New comment by schemescape in "A 2024 Plea for Lean Software (with running code)"

schemescape — Fri, 19 Jan 2024 01:05:50 +0000

What are some current examples of lean software, esp. related to developing and deploying software?

i3? SourceHut? QuickJS? Edit: BusyBox!

I know it’s an open-ended question, but I’m curious to see thoughts from others.

For context, possibly in reaction to porting an app via Electron, I’ve been trying to repent by finding a minimal development environment for hobby projects. I’m not sure it qualifies as “lean”, but Emacs and SBCL strike a nice balance for me right now.

So is it not official Debian? If so, that’s concerning!

Thanks, that makes more sense than automatically granting privileges. It definitely seems easy to mix up those two terms, however!

New comment by schemescape in "Penrose – Create diagrams by typing notation in plain text"

schemescape — Mon, 15 Jan 2024 03:42:08 +0000

Looks like that depends on the “canvas” package, which appears to use Cairo/Pango for text, similar to Graphviz.

This is great! I wanted something I could compile (the native code) to WebAssembly for use in a Deno-based SSG, and this looks promising.

schemescape — Mon, 15 Jan 2024 01:32:17 +0000

Does this require a browser (or browser engine) for rendering (like Mermaid.js)? Or can it render (esp. to SVG) without a browser (like Graphviz)?

Penrose appears to be written in TypeScript, so my assumption is that it needs a browser.

> I really don't like this aspect of GitHub that people who have submitted a typo fix gain additional privileges on the repo by default.

What privileges do they gain? Anything other than the one you mentioned?

This was definitely not obvious to me, so thanks for bringing it up!

schemescape — Sat, 13 Jan 2024 20:06:27 +0000

How paranoid should I be about routers from companies like Cudy that I’m not familiar with? My intuition is “very paranoid, even if I replace the firmware with OpenWRT”.

Am I being too paranoid?

Is it just Safari or are the “turn left” and “turn right” icons nearly identical?
