Some of my #toolforge projects for #wikidata and #wikipedia (Mix'n'match, baGLAMa2) use #RustLang with a permanently running background process, which heavily uses multithreaded async.

There is an issue across these (pretty independent) codebases that the process runs fine for hours, then pauses, without explanation. Mutex locks, reqwest timeouts, all checked. Very difficult to debug.

Any ideas what it could be, or how to debug it?

Wrote a little binary in #rustlang to scan a directory tree on disk, find image files with coordinates in EXIF, and output an aggregate. Can write JSON or KML. Bug reports, feature requests, and PR/MRs welcome

So this is basically a shitpost, but if you ever thought to yourself "wow, I sure wish I had C++-style dynamic allocator mixing in #RustLang !" then here's how to do that cleanly on nightly: https://gist.github.com/Tamschi/cd6d490c5392d6fadcd92c075c87db36

I did this as a quick "how much of a mess would it be to implement this usefully?" and DIDN'T TEST IT. License is CC0 because how else would you even do this?

A version of this that's also `Clone` is left as exercise to the reader.

Writing shellcodes in assembly is not only hard, but also architecture dependent, and impossible to reuse

instead, let's see how to craft advanced & platform independent shellcodes in Rust:

It's an open secret that most of the time and costs spent on any serious software project are from maintenance.

#Rust is moving fast, and its ecosystem too, so it's necessary to automate your projects' maintenance

Monomorphization, Static vs Dynamic dispatch, Trait Objects...

Generics allow programmers to write less code and produce less bugs, but are not easy to grasp.

So here is the second part of my introduction to Rust generics:
https://kerkour.com/rust-generics-trait-objects

#Rust #Rustlang #100DaysOfCode #code #programming

Generics allow programmers to write less code by reusing functions, structures & traits and thus produce less bugs

But generic #programming can be hard to learn so here is the simplest introduction to Rust generics:

Tests are not meant to be manually run each time you write code. It would be a bad usage of your precious time as Rust takes a loooong time to compile

Typosquatting attacks are well-known, but there are attacks that are way more pernicious and that may provide better results

Bitsquatting attacks

Here is how it works and how to perform it using #rust

The most effective phishing attack I ever witnessed was not an email campaign. It was an evil twin attack. The success rate was in the order of 80%-90%

A few weeks ago, I wrote: "I believe that Rust moves too fast" and "a programming language is a platform".

Some people raised good objections, so I thought it would be good to write a follow-up
