how user agents became a lying mess

May be a replacement for a current postfix+dovecot+rspamd+L+ratio setup. Notably supports JMAP, although most clients don’t anyways.

Looks useful, although I don’t remember any context in which it would be useful. Worth a try anyway.

sadly, doesn’t provide links, but most is googlable

This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine.

Another take on io_uring in Rust. Doesn’t bring its own runtime, instead choosing to integrate with tokio.

Looks really cool. I wonder what’s inside.

The [board] game is about creating a small shellcode in memory by copying existing instructions and then exploiting a buffer overflow to jump into it, so that you can overwrite your opponent’s return address to force them to go to the game_over() function.There are other mechanics as well and more layers of strategy (like setting the exception handler or monkeypatching).

The site contains all the lectures, project materials and tools necessary for building a general-purpose computer system and a modern software hierarchy from the ground up.

A paper about message-passing memory allocator: could be useful for actor systems.

A fresh take on typesetting

When it comes to security, we care about limiting access of each entity of a system to as few other entities as possible. Network input, executables and users must be able to reach only those resources, which are necessary to perform the defined server tasks. Principle of least priviledge.

Generally, it's better to implement as many layers of security as possible. Although, there is no way to make a server 100% bullet proof - it's a huge endless topic, this article covers some feasible essential systemd tunables that give us a layer of protection.

Life is hard. Some days are at the absolute limit of what we can manage. Some days are worse than that. Eating—picking a meal, making it, putting it into your facehole—can feel like an insurmountable challenge. We wrote this cookbook to share our coping strategies. It has recipes to make when you’ve worked a 16-hour day, when you can’t stop crying and you don’t know why, when you accidentally woke up an Eldritch abomination at the bottom of the ocean. But most of all, this cookbook exists to help Sad Bastards like us feel a little less alone at mealtimes.

WebKit's FTL JIT now uses a new backend on OS X — the Bare Bones Backend, or B3 for short, replaces LLVM as the low-level optimizer.

Designed to bring aggressive C-like optimizations to the largest variety of JavaScript programs.
