Story: Redis and its creator antirez | Brachiosoft Blog
This article is translated from the original Chinese edition. In the world of databases, Redis stands out as unique.

My 24 year old HP Jornada can do things your modern iPhone still can't do! Published: 15-06-2023 01:30 | Author: Remy van Elst | Text only version of this article ❗ This post is over two years old. It may no longer be up to date. Opinions may have changed. I like to tinker with old hardware. The DEC PDP-8 is my favorite retro computer and Office 2003 is the best version ever released IMHO.

There's been a lot of discussion recently about how "Safari is the new IE" (1, 2, 3, 4, 5). I don't want to rehash the basics of that, but I have seen some interesting rebuttals, most commonly: Safari is actually protecting the web, by resisting adding unnecessary and experimental features that create security/privacy/bloat problems. That is worth further discussion, because it's widespread, and w
A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from an interesting angle. So let's say you use pygame to write a simple game in Pytho

Downtown Doug Brown » The invalid 68030 instruction that accidentally allowed the Mac Classic II to successfully boot up
This is the story of how Apple made a mistake in the ROM of the Macintosh Classic II that probably should have prevented it from booting, but instead, miraculously, its Motorola MC68030 CPU accidentally prevented a crash and saved the day by executing an undefined instruction. I’ve been playing around with MAME a lot lately. If you haven’t heard of MAME, it’s an emulator that is known best for its
