"Yes, re-opening.".> Given these positive signals, we would welcome contributions to integrate a performant and memory-safe JPEG XL decoder in Chromium. In order to enable it by default in Chromium we would need a commitment to long-term maintenance. With those and our usual laun

For context, djb has been doing and saying these things since he was a college student: While a graduate student at the University of California at Berkeley, Bernstein completed the development of an encryption equation (an "algorithm") he calls "Snuffle." Bernstein wishes to pub

ProTip: use PNPM, not NPM. PNPM 10.x shutdown a lot of these attack vectors.1. Does not default to running post-install scripts (must manually approve each)2. Let's you set a min age for new releases before pnpm install will pull them in - e.g. 4 days - so publishers have time

OOP-bashing seems fashionable nowadays.Yes, and for just cause. OOP was invented in Simula76 (1976) and popularized in C++ (1982). OOP solved a very real problem of allowing applications to logically scale in memory constrained systems by allowing logic to grow independently an

В движке Quake скрыты индикаторы производительности TURTLE, RAM, DISC и NET из pak0.pak/gfx.wad, отображаемые в левом верхнем углу экрана. Они помогали разработчикам id Software диагностировать проблемы: TURTLE (черепаха) появляется при FPS ниже 10 (host_frametime >0.1с), активируется командой showturtle 1/0 в SCR_DrawTurtle; предназначен для проверки полигонов в картах. RAM сигнализирует о thrashing кэша поверхностей (surfacеs из текстур+lightmap) в том же кадре, вызывая "death spiral" с резким падением FPS (D_SCAlloc).

DISC мигает при чтении файлов с HDD (Sys_FileRead в SCR_DrawRam), давая визуальную обратную связь о загрузке. NET отображается, если пакеты от сервера не приходят >300 мс (SCR_DrawNet), помогая игрокам оценивать пинг. Все индикаторы видны одновременно при тяжёлой нагрузке; в Quake 2 scr_showturtle бесполезен. Обнаружены при фиксе бага в Chocolate Quake.

• Обсуждение индикаторов Quake: NET для потери пакетов (не высокий пинг), turtle/tortoise для низкого FPS, DISC/RAM для диск/HDD/RAM нагрузки.
• Коррекции от автора и комментаторов: опечатки (prevent→present, SCR_DrawRam→Draw_BeginDisc), уточнения по коду, reconnect и портам.
• Ностальгия: воспоминания о 56k/LAN, живое сообщество, порты (Chocolate Quake, Quakespasm), влияние на CoD/Half-Life Alyx.
• Вопросы о source ports, почему нет аналога Chocolate Doom раньше, turtle-команда как отсылка к Logo.

It surprises that they are still teaching parsing techniques that are based on limitation from 40 years ago, when memory was limited and you had to parse a file one character at the time. Why not start with a back-tracking recursive descent parser on a file stored in memory? Can

https://archive.is/v4dPa One of the more disturbing things I read this year was the my boyfriend is AI subreddit.I genuinely can't fathom what is going on there. Seems so wrong, yet no one there seems to care.I worry about the damage caused by these things on distressed people. W

There's a model of computation called 'interaction nets' / 'interaction calculus', which reduces in a more physically-meaningful, local, topologically-smooth way.I.e. you can see from these animations that LC reductions have some "jumping" parts. And that does reflect LC nature,

• @jjmarr предлагает создать аудиоклип с фразой "government cell phone detected" для пранка над бывшими госслужащими.
• @quamserena сначала предлагает скопировать существующий аудиофайл для этой цели.
• @quamserena затем предупреждает, что это может создать OPSEC-проблемы.
• @quamserена отказывается помогать из-за потенциальных OPSEC-рисков.

Why are all the comments here so weird? It's like people saw (but didn't read) an article entitled "Man Opens a Taqueria in his Hometown" and the only responses are1) Why didn't he open it in my hometown? This location isn't convenient for me.2) Wouldn't it be better for someone
