  • The Belgian traffic? Almost entirely from a single residential IP — one box that sent over 156,000 login attempts, more than the entire country of Germany. It just sat there, hammering echo “\x6F\x6B” over and over, every single second, for weeks. Relentless.

    Had a funny similar thing, there’s some weird person/people that randomly probe and attack a specific game’s community hosted dedicated servers; and one week this specific IP address out of Virginia was just hammering one of mine, with what amounts to a specific byte sequence, then an incrementing number of the packet (until it wrapped around). Then it stopped. Weird shit.


  • The course I’m in uses Algorithms (Fourth Edition) by Sedgwick and Wayne[1], and I consider it pretty good. A large focus is on clear implementations that demonstrate the core parts of each algorithm, without getting bogged down in specialization, which I can appreciate. The book also has very good visualizations (they call them traces) if you learn better visually. The only real downside is it’s entirely Java oriented material. But since you’re working with C# this probably isn’t a deal breaker.

    The other recommendation in the thread is Introduction to Algorithms, which I’ve read chapters of (used as reference) — personally it’s ok, definitely more abstract and math heavy, so if that’s something you want or appreciate then it’s a good option.

    There’s also The Art of Computer Programming by Knuth, which to me is grad level stuff, very very math heavy, but also brilliant, if you can keep up.

  • It’s not the point of the article, but I think it nonetheless speaks to the power that the community-of-communities model provides.

    The algorithmic content surfacing models are what primarily rot online interaction. Having all-encompassing sites is another cause. Letting people join communities with shared values, and those communities collectively deciding who they interact with, is a fundamental working model of human societies since prehistory.
