What do you think of my code for a classic interview question? ( lemm.ee )

I’ve found this interview question at GeeksForGeeks and decided to actually code it in C++. The program currently prints the “value” of the horses (which is inaccessible by the coder so they can’t just look up who is number 1) and then proceeds to sort them and find the position of numbers 1,2 and 3 in a 5x5 matrix with...

How do devs protect the company's database from bugs or exploits with each released app/site update?

With ever the constant updates to popular and important apps and websites, how do the developers ensure the update preserves the user and site’s original database, considering the possibility that the updates might contain data-corruptive bugs or exploits for users?...

Interval Tree Clocks, or how to track causality in a distributed network ( ferd.ca )

In a comment on my “right to be forgotten” proposal I mentioned causality tracking (so eg. figuring out whether event A happened before or after event B) in distributed networks as an example of a hard problem, and I figured I’d share a blog post (not mine) on one of the more modern techniques that’s still very much...

Worth learning vim/emacs?

Im considering spending some serious time learning one of the above. Two principle engineers I work with exclusively use them, and watching them work is incredible, the speed they move and get things done is pure wizadry. Can anyone learn this skill? For what it’s worth, the alternative is learning VScode. I’ve exclusive...

v86 - x86 emulator running entirely in web browsers ( copy.sh )

Unlike other browser-based x86 emulators, OSes running inside v86 can actually access internet via a transparent proxy relay. You can load your own OS images, or choose one from a pretty comprehensive list (Arch Linux, Windows 1.01 to 2000, SerenityOS, *BSD, Android 1.6, Haiku, QNX, and so on)....

I developed a platform to navigate with slow or unstable connections ( blaze.cyclic.app )

Recently, I ran out of mobile data on my phone, and I was forced to browse at a significantly reduced speed. It was so slow that it was practically unusable, except for messaging apps. So, I developed a platform in the form of a search engine that allows browsing and accessing information while exchanging a negligible amount of...

Good resources for learning Rust?

I’m looking to get a lemmy bot figured out for posting sports scores in real-time (or near it) like Reddit had for NHL games. The lemmy api reference states that rust has the api as a loadable library, but I’ve only ever done C/C++ and python. Anything Coursera style to get a basic overview of how to get started in Rust?...
