What if: AI inserted a bug in every PR and you had to find it before you can approve
What if GitHub made you take a quiz about your PR before requesting reviews, to make sure you know what's in it? And if you don't...

I recently watched a talk about Rust and they where so enthusiastic about the `env!()` macros. They said "no other major language does that". Yet every JS bundler has a similar feature.

The JSs ecosystem's way of "you can import any type of file and just configure how that should be interpreted" is actually really nice. Every language should have that.
How does an interpreted language somehow have some of the best support for compile time computation

I've been researching #webrings to add my site to, and I find a lot of them have broken links, are no longer maintained, or sites where it's impossible to actually find the widgets.

I've said this before but it seems you need a reminder: doing exactly what you complained about your enemy doing years ago is not "ironic". It's just hypocritical

My Spider solitaire game now has a cheat where you shuffle more decks into the stack. All it really does is dig you in deeper when you get in trouble. Anyway, I finished after using the entire world supply of cards.

I found something interesting. In PostgreSQL, if you have a statement like INSERT ... ON CONFLICT DO UPDATE .. on a table with an auto-incrementing primary key, it will reserves an ID for the row even on conflict.
Since I'm updating the same record many times, I now have massive gaps between my IDs

I made a simple command line spider solitaire game in #Rust.
It has somewhat balanced cheats that can get me to nearly 50% winrate.

#programing #challenge Can you find if a graph is planar using as few bytes as possible? byte-heist.com/challenge/56...
A quite difficult challenge but very mathematically satisfying. I've been researching #graph #theory for days.

If the new York Times is so bad, why do people keep reposting every single article. Yes it has a political leaning slightly different from this sites. I get it.
You don't need to give it attention if you hate it so much.
