2025-11-27 Crafting Interpreters { craftinginterpreters.com }
Crafting Interpreters contains everything you need to implement a full-featured, efficient scripting language. You’ll learn both high-level concepts around parsing and semantics and gritty details like bytecode representation and garbage collection. Your brain will light up with new ideas, and your hands will get dirty and calloused. It’s a blast.
Starting from main(), you build a language that features rich syntax, dynamic typing, garbage collection, lexical scope, first-class functions, closures, classes, and inheritance. All packed into a few thousand lines of clean, fast code that you thoroughly understand because you write each one yourself.

2025-12-27 floooh/chips: 8-bit chip and system emulators in standalone C headers { github.com }
A toolbox of 8-bit chip-emulators, helper code and complete embeddable system emulators in dependency-free C headers (a subset of C99 that compiles on gcc, clang and cl.exe).
Tests and example code is in a separate repo: https://github.com/floooh/chips-test
The example emulators, compiled to WebAssembly: https://floooh.github.io/tiny8bit/
For schematics, manuals and research material, see: https://github.com/floooh/emu-info
The USP of the chip emulators is that they communicate with the outside world through a 'pin bit mask': A 'tick' function takes an uint64_t as input where the bits represent the chip's in/out pins, the tick function inspects the pin bits, computes one tick, and returns a (potentially modified) pin bit mask.
A complete emulated computer then more or less just wires those chip emulators together just like on a breadboard.
In reality, most emulators are not quite as 'pure' (as this would affect performance too much or complicate the emulation): some chip emulators have a small number of callback functions and the adress decoding in the system emulators often take shortcuts instead of simulating the actual address decoding chips (with one exception: the lc80 emulator).

A Simple UI Animation System A minimal tweening system for immediate mode UIs that tracks only active animations in a fixed array, exposes an update/start/get API, and lets your program store only target values while rendering uses animated values.
A Simple Serialization System A self-describing binary serialization format built from tagged values (including arrays and objects), designed for simple implementation, linear reading, easy inspection, and forward/backward compatibility, with an optional string interning extension.
Textbox Behaviour A reference specification for textbox editing behavior that breaks the problem into caret/selection state plus movements, operations, and commands, covering single-line, multi-line, and mouse-driven selection details.
Level Generation Using Markov Chains A method for generating 2D tilemap levels by training a Markov chain on one-dimensional row strings from example maps, then generating new rows and optionally placing entities by scanning for special tiles.
A Simple Undo System An undo/redo approach where code marks memory blocks before they might change and commits at interaction end to diff and record only changed blocks, implemented with undo, redo, and temporary stacks.
lite: An Implementation Overview An implementation tour of the lite text editor, describing its Lua/C split, frame loop, cooperative coroutine-based background work, document management, incremental syntax highlighting, view-based UI layout, and plugin approach.
microui v2: An Implementation Overview An implementation overview of a tiny immediate mode UI library in ANSI C that turns input into draw commands within fixed buffers, explaining windows and controls, hover rules, z-ordering in one command list, and bounded state storage.
Cached Software Rendering A software rendering technique that lets the app redraw as if every frame is full while the renderer redraws only changed regions using a command buffer plus a per-cell hash grid to detect dirty areas.
2025-11-27 A Very Fast 64–Bit Date Algorithm: 30-40% faster { www.benjoffe.com }
In this article I present my final very fast date conversion algorithm. It represents a significant speed gain — being similar in magnitude to the speed gains achieved by the previous fastest algorithm (Neri-Schneider 2021) over its predecessor (C++ Boost). The full algorithm implementation in C++ is released as free open source software (BSL-1.0 License).
The algorithm provides accurate results over a period of ±1.89 Trillion years, making it suitable to process the full UNIX 64–bit time (in seconds).
The entire algorithm has been re-written top-to-bottom, with various micro-optimisations, but three main new ideas:
- Years are calculated *backwards*, which removes various intermediate steps.
- The step to calculate day-of-year is *skipped*, instead using a year-modulus-bitshift technique which removes a division.
- The *"Julian Map"* technique is utilised from my previous article, which speeds up the 100/400 year calculation, removing two more hardware multiplications.
While fast date algorithms have always used 7 or more expensive computations (multiplication, division, or modulus by non-power-of-2 numbers), this algorithm uses only 4 multiplications. The speed-gain can be seen at a glance.

anthay/ELIZA: A Simulation in C++ of Joseph Weizenbaum’s 1966 ELIZA
I’ve made in C++ what I think is an accurate simulation of the original ELIZA. It is a console application that takes as input the original format script file, which looks like a series of S-expressions, and then waits for the user to type a line of text before responding with a line of text of its own.
