A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

Welcome to the “Awesome ChatGPT Prompts” repository! While this collection was originally created for ChatGPT, these prompts work great with other AI models like Claude, Gemini, Hugging Face Chat, Llama, Mistral, and more. ChatGPT is a web interface created by OpenAI that provides access to their GPT (Generative Pre-trained Transformer) language models. The underlying models, like GPT-4o and GPT-o
An interesting twist in my recent usage of SQLite was the fact that I noticed my research scripts and the database intertwine more. SQLite is unique in that it really lives in-process, unlike standalone database servers. There is a feature to that which does not get used very frequently, but can be indispensable in some situations. By the way, the talk about the system that made me me to explore S
A History of Clojure
71 A History of Clojure RICH HICKEY, Cognitect, Inc., USA Shepherd: Mira Mezini, Technische Universität Darmstadt, Germany Clojure was designed to be a general-purpose, practical functional language, suitable for use by professionals wherever its host language, e.g., Java, would be. Initially designed in 2005 and released in 2007, Clojure is a dialect of Lisp, but is not a direct descendant of any
Patching GCC to build Actually Portable Executables | Blog Needs a Name
Patching GCC to build Actually Portable Executables2023-07-13: I wrote a ~2000-line gcc patch to simplify building Actually Portable Executables with Cosmopolitan Libc. Now you can build popular software such as bash, curl, git, ninja, and even gcc itself, with Cosmopolitan Libc via the ./configure or cmake build system, without having to change source code, and the built executables should run on
の類ですね。出現頻度も高く、postfixに負荷がかかるし、第一気持ち悪いので、自動的にblockする方法を考えました。 これは、Linuxサーバーで不正なパケットを検知し、自動的にブロックするPythonスクリプトです。syslogのログファイルを監視し、指定された正規表現パターンにマッチする不正なパケットをブロックするために、iptablesを使用します。また、特定のIPアドレスがブロックされている期間を追跡するために、sqlite3を使用します。 このスクリプトを使用することで、不正なパケットを自動的にブロックし、サーバーの負荷を軽減できます。また、手動でIPアドレスをブロックする必要がなく、セキュリティの向上に役立ちます。 fail2banという類似するシステムがあります。ipblock.pyはfail2banのように複数のlogを監視しません。何回か、その攻撃があったら、処断する
