Sound As Pure Form: Music Language Inspired by Supercollider, APL, and Forth

news.ycombinator.com Unknown 2025-09-03 20:17:51

WHAT This program is called: "A tool for exploring sound as pure form." or "sound as pure form" or "sapf" It is an interpreter for a language for creating and transforming sound. The language is mostly functional, stack based and uses postfix notation similar to FORTH. It represents audio and control events using lazy, possibly infinite sequences. It intends to do for lazy sequences what APL does for arrays: provide very high level functions with pervasive automatic mapping, scanning, and reduct

Homegrown Closures for Uxn

news.ycombinator.com Unknown 2025-09-07 07:29:35

Homegrown closures for uxn at least, kind of... For a week or so now, I've been writing niënor, a "lispy environment for uxn". I did not want it to become a full-blown lisp but just another way of writing uxntal. Uxntal is a bit too dense for my liking, and I prefer lisp/scheme s-expression syntax. Niënor is just a compiler and a macroexpander that takes in scheme-like code and spits out uxn roms. This article describes my homegrown method of creating lexically scoped closures in this environ

Game Hacking – Valve Anti-Cheat (VAC)

news.ycombinator.com Unknown 2025-09-09 15:19:31

Intro In 2002 Valve created an Anti-Cheat solution called “Valve Anti-Cheat” aka VAC. The first game they implemented VAC into was Counter-Strike. When VAC was introduced it only operated in User Mode (Still does) meaning it runs entirely in user space and has no kernel component. Below is a list of games that use VAC.. Call of Duty: Modern Warfare 2 Call of Duty: Modern Warfare 3 Counter-Strike (video game) Counter-Strike: Condition Zero Counter-Strike: Source Counter-Strike 2 Day of Defeat

Simplest C++ Callback, from SumatraPDF

news.ycombinator.com Unknown 2025-09-15 04:26:38

SumatraPDF is a Windows GUI application for viewing PDF, ePub and comic books written in C++. A common need in GUI programs is a callback. E.g. when a button is clicked we need to call a function with some data identifying which button was clicked. Callback is therefore a combo of function and data and we need to call the function with data as an argument. In programming language lingo, code + data combo is called a closure. C++ has std::function<> and lambdas (i.e. closures). Lambdas convert

Writing a Truth Oracle in Lisp

news.ycombinator.com Unknown 2025-09-12 08:50:53

This post assumes some familiarity with typed functional programming, Lisp, and formal logic. Today we will attempt to write a truth oracle in Lisp. By "truth oracle," I mean a program that can determine whether arbitrary mathematical statements are true or false. This might sound impossible, due to first-order logic being undecidable, but let's try anyway. Before that, though, we need to go over some required concepts. Extracting information from proofs First, sometimes, we can extract info
