My business model? Ensuring that my technology can never be easily reproducibly rebuilt by others and subtly undermining any efforts to produce easy, complete, accessible and up to date documentation so that you’re forced to hire me as a consultant just to be able to use it

Using .unwrap() in production and causing a Cloudflare outage is the funniest thing ever. It’s a totally fine way of error handling, because if error -> crash 😊
It's even funnier that the function is already a `Result<>` so they could have propagated the error if they don't want to handle it here

I am currently working on a project involving formally verifying Rust code for correctness and some other funny properties.
for that I have decided to use the “hax” tool which allows you to verify Rust code in F*, which sounds amazing, right?
It does, but working with it has been absolute headache

the way modern universities teach programming, especially C/C++ or Java (with OOP) is criminal.
it is such an absolutely lame and tasteless approach, feeding them absolute garbage disguised as an introduction to programming and/or data structures & algorithms.

after a lot of fighting with the UEFI and some very weird firmware issues, I am proud to announce that I permanently deleted Windows and installed Fedora on KDE Plasma!!!!
could not be happier right now
now both of my PCs (desktop and laptop) are running Fedora on KDE woohoo!

One curious thing on this site about speaking out against the encroachment of LLMs is that inevitably you get accused of being anti-tech. I don’t hate technology. I’ve used machine learning in my own code before. But I also recognize that oligarchs are so hellbent on pushing this tech for a reason.

as controversial as this may be, I actually agree with a lot of the “good” code practices in the Linux kernel.
they are quite “battle-hardened” in that they guarantee that bad code will be spotted and fixed before it goes into production.
the opinionated “leader” notwithstanding, it’s very smart.
