I’m talking about programs that can’t be improved no matter what. They do exactly what they’re supposed to and will never be changed.
It’ll probably have to be something small, like cd or pwd, but does such a program exist?
Pretty certain cd and pwd have changed over the years. The kernel hasn’t remained the same so the commands that use it wont and now we have faster methods to do various things like getting file data the commands that depend on it will change. Less quickly than something that is still gaining features but bit rot is a very real effect since every single part of software is in constant flux.
- vi
- grep
- curl
Ehhh, for curl there is a few features they’re working on (like better websocket support), and I’m sure there’s lots of optimizations that could be made, given how complex a project it is…
Ed. It’s the standard text editor.
Windows event viewer… You open it, go to the toilet, to the shower, take a coffee, … and only 2 more minutes later, it shows you the entries…
It’s so perfect, they never had to improve it in decades.
/s
I would say git, tex, sqlite, Clojure, Steel banks common lisp are some of the candidates.
Perfect doesn’t meen “not any bugs fixes or features needed” to me. I can’t really define what it means to me…
emacs can only be improved no matter what but it should count
As a vim user, I agree that it can only be improved.
For software to be perfect, can not be improved no matter what, you’d have to define a very specific and narrow scope and evaluate against that.
Environments change, text and data encoding and content changes, forms and protocol of input and output changes, opportunities and wishes to integrate or extend change.
pwdseems simple enough.cdI would already say no, with opportunities to remember folders, support globbing, fuzzy matching, history, virtual filesystems. Many of those depend on the environment you’re in. Typically, shells handle globbing. There’s alternativecdtools that do fuzzy matching and history, and virtual filesystems are usually abstracted away. But things change. And I would certainly like an interactive and fuzzy cd.Now, if you define it’s scope, you can say: “All that other stuff is out of scope. It’s perfect within it’s defined target scope.” But I don’t know if that’s what you’re looking for? It certainly doesn’t mean it can’t be improved no matter what.
If you just need the functionality then fzf does (among other things) exactly that. Interactive fuzzy cd. If you use the shell bindings you can do
cd foo/bar/**<tab>to get a recursive fuzzy matching or you can do alt+c to immediately find any subdirectory and directly cd into it upon pressing enter. You can also use Ctrl+T to find and insert a path into the prompt.
Winamp! It probably had some bugs or security issues but functional it was perfect imo.
TeX?
Development is considered to be complete, and the version numbering is just adding a digit of pi. Last change was 5 years ago.
This was going to be my point. The idea that as the software slowly makes new releases the version number more and more closely approximates Pi
TeX. Best documented source, and last bug found was 12 years ago.
The 2021 release of Tex included several bug-fixes, so not quite 12 years:

See also the following list of potential bugs, that may be included in the planned 2029 release of Tex:
https://tug.org/texmfbug/newbug.html
That said, Tex is still an impressive piece of software
Thanks for the update, I somehow missed that.
To be honest, they didn’t make it easy to find
Htop
Btop?
Idk if it’s perfect but I really like the “literate programming” version of `
This is not the original, but here is one version of it : https://github.com/zyedidia/Literate/blob/master/examples/wc.lit
Your sentence abruptly ends in a backtick - did you mean to include something more? Maybe “
wc”?
A program that just prints “Hello World” to the screen and quits.
…that supports Unicode? Which encodings? Or only ASCII? Unicode continues to change.
I wouldn’t be very confident that it won’t change or offer reasonable opportunities for improvement.
I wanted to say VLC because to me, it’s the gold standard of fully working open-source software that just destroys the commercial competitors.
But it’s not perfect only because society changes. New video formats forces VLC and open-source devs to adapt. Bigger video and new tech specs require VLC to update. If it wasn’t for all those external needs, VLC would be perfect.
Did I also mentioned the many times rich companies wanted to buy VLC and they laughed?
Personally I prefer MPV but yeah both just wrap around FFMPEG
It’s worth noting that most commercial multimedia software is also more or less a wrapper around ffmpeg
LaTeX
Not sure about LaTeX, but TeX is widely considered to be almost “perfect” code.
TeX will be perfect after Knuth dies and the version number is incremented to π.
Error: Too many unprocessed floats.
ugh, no way. It might do a fine job with typesetting, but the user experience is utterly awful and that’s very unlikely to change because of design choices over 40+ years. If you don’t think so, give typst a real try.
