18 rules of Software Engineering

  1. You will regret complexity when on-call
  2. Stop falling in love with your own code
  3. Everything is a trade-off. There’s no “best” 3. Every line of code you write is a liability 4. Document your decisions and designs
  4. Everyone hates code they didn’t write
  5. Don’t use unnecessary dependencies
  6. Coding standards prevent arguments
  7. Write meaningful commit messages
  8. Don’t ever stop learning new things
  9. Code reviews spread knowledge
  10. Always build for maintainability
  11. Ask for help when you’re stuck
  12. Fix root causes, not symptoms
  13. Software is never completed
  14. Estimates are not promises
  15. Ship early, iterate often
  16. Keep. It. Simple.

Solid list, even though 14 is up for debate in my opinion: Software can be completed. You have a use case / problem, you solve that problem, done. Your software is completed now. There might still be bugs and they should be fixed – but this doesn’t “add” to the program. Don’t use “software is never done” as an excuse to keep adding and adding stuff to your code.

↳ In-reply-to » Just discovered how easy it is to recall my last arg in shell and my brain went 🤯 How come I've never learned about this before!? I wonder how many other QOL shortcuts I'm missing on 🥲

@aelaraji@aelaraji.com I use Alt+. all the time, it’s great. 👌

FWIW, another thing I often use is !! to recall the entire previous command line:

$ find -iname '*foo*'
./This is a foo file.txt

$ cat "$(!!)"
cat "$(find -iname '*foo*')"
This is just a test.

Yep!

Or:

$ ls -al subdir
ls: cannot open directory 'subdir': Permission denied

$ sudo !!
sudo ls -al subdir

↳ In-reply-to » Fuck me sideways, Rust is so hard. Will we ever be friends?

@prologic@twtxt.net I’m trying to call some libc functions (because the Rust stdlib does not have an equivalent for getpeername(), for example, so I don’t have a choice), so I have to do some FFI stuff and deal with raw pointers and all that, which is very gnarly in Rust – because you’re not supposed to do this. Things like that are trivial in C or even Assembler, but I have not yet understood what Rust does under the hood. How and when does it allocate or free memory … is the pointer that I get even still valid by the time I do the libc call? Stuff like that.

I hope that I eventually learn this over time … but I get slapped in the face at every step. It’s very frustrating and I’m always this 🤏 close to giving up (only to try again a year later).

Oh, yeah, yeah, I guess I could “just” use some 3rd party library for this. socket2 gets mentioned a lot in this context. But I don’t want to. I literally need one getpeername() call during the lifetime of my program, I don’t even do the socket(), bind(), listen(), accept() dance, I already have a fully functional file descriptor. Using a library for that is total overkill and I’d rather do it myself. (And look at the version number: 0.5.10. The library is 6 years old but they’re still saying: “Nah, we’re not 1.0 yet, we reserve the right to make breaking changes with every new release.” So many Rust libs are still unstable …)

… and I could go on and on and on … 🤣

So I was using this function in Rust:

https://doc.rust-lang.org/std/path/struct.Path.html#method.display

Note the little 1.0.0 in the top right corner, which means that this function has been “stable since Rust version 1.0.0”. We’re at 1.87 now, so we’re good.

Then I compiled my program on OpenBSD with Rust 1.86, i.e. just one version behind, but well ahead of 1.0.0.

The compiler said that I was using an unstable library feature.

Turns out, that function internally uses this:

https://doc.rust-lang.org/std/ffi/struct.OsStr.html#method.display

And that is only available since Rust 1.87.

How was I supposed to know this? 🤨🫩

Transcrição:

O resultado das últimas eleições legislativas veio moralizar um sector da população que passou a diabolizar a “esquerda” sem quaisquer tipos de restrições de linguagem, “crucificando” pessoas pelas suas posições humanistas e antifascistas, e vangloriando, abertamente e sem pudor, por exemplo, o antigo regime. Nesse particular, tem-se destacado Gabriel Mithá Ribeiro, deputado do Chega eleito por Leiria que, nas redes sociais e em artigos publicados no Observador, nos tem mostrado ser uma figura controversa e polarizadora, não apenas pelas suas opiniões, mas pela forma como as expressa: provocadoras, desdenhosas e, por vezes, perigosamente revisionistas.

[$] An end to uniprocessor configurations
The Linux kernel famously scales from the smallest of systems to massive
servers with thousands of CPUs. It was not always that way, though; the
initial version of the kernel could only manage a single processor. That
limitation was lifted, obviously, but single-processor machines have always
been treated specially in the scheduler. That longstanding situation may
soon come to an end, though, if this patch\
series from Ingo M … ⌘ Read more

New oil and gas fields incompatible with Paris climate goals
