This is The Entire Computer Science Curriculum in 1000 YouTube Videos In this article, we are going to create an entire Computer Science curriculum using only YouTube videos. The Computer Science curriculum is going to cover every skill essential for a Computer Science Engineer that has expertise in Artificial Intelligence and its subfields, like: Machine Learning, Deep Learning, Computer Vision,
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased

In general, what do you need in order to communicate? A common language (for the two ends to understand) A way to address who you want to communicate with A Connection (so the content of the communication can reach the recipients) What is TCP/IP? A set of protocols that define how two or more devices can communicate with each other. To learn more about TCP/IP, read here What is Ethernet? Ethernet
The end of classical computer science is coming, and most of us are dinosaurs waiting for the meteor to hit. I came of age in the 1980s, programming personal computers such as the Commodore VIC-20 and Apple ][e at home. Going on to study computer science (CS) in college and ultimately getting a Ph.D. at Berkeley, the bulk of my professional training was rooted in what I will call “classical” CS: p
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
Lessons from Writing a Compiler
The prototypical compilers textbook is: 600 pages on parsing theory. Three pages of type-checking a first-order type system like C. Zero pages on storing and checking the correctness of declarations (the “symbol table”). Zero pages on the compilation model, and efficiently implementing separate compilation. 450 pages on optimization and code generation. The standard academic literature is most use
Hello everyone, Asahi Lina here!✨ marcan asked me to write an article about the M1 GPU, so here we are~! It’s been a long road over the past few months and there’s a lot to cover, so I hope you enjoy it! What’s a GPU?You probably know what a GPU is, but do you know how they work under the hood? Let’s take a look! Almost all modern GPUs have the same main components: A bunch of shader cores, which

A huge thanks goes out to all the beta testers on discord and all the contributors to
Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C
Happy New Year everyone! In late December 2023 (Christmas Day to be precise), CPython core developer Brandt Bucher submitted a little pull-request to the Python 3.13 branch adding a JIT compiler. This change, once accepted would be one of the biggest changes to the CPython Interpreter since the Specializing Adaptive Interpreter added in Python 3.11 (which was also from Brandt along with Mark Shann
4 Pandas Anti-Patterns to Avoid and How to Fix Them
pandas is a powerful data analysis library with a rich API that offers multiple ways to perform any given data manipulation task. Some of these approaches are better than others, and pandas users often learn suboptimal coding practices that become their default workflows. This post highlights four common pandas anti-patterns and outlines a complementary set of techniques that you should use instea

Free-threaded CPython is ready to experiment with!Published July 12, 2024 First, a few announcements: Yesterday, py-free-threading.github.io launched! It's both a resource with documentation around adding support for free-threaded Python, and a status tracker for the rollout across open source projects in the Python ecosystem. We hope and expect both of these to be very useful, with the status tra
A Walk with LuaJIT
The following is a chronicle of implementing a general purpose zero-instrumentation BPF based profiler for LuaJIT. Some assumptions are made about what this entails and it may be helpful to read some of our other work in this area. One major change from prior efforts is that instead of working with the original Parca unwinder we are now working with the OpenTelemetry eBPF profiler. If you missed t
Toggle dark mode I may be late to the party, but LangGraph lets you build complex workflow architectures and codify them as powerful automations. Also LLMs, if you want. But you don’t have to! LLM Architecture I always liked the idea of “flow-based” programming. PureData, DaVinci Resolve, Node Red... they all appeal to me. I also always liked the idea of running LLMs locally, rather than spending
Lately I’ve been messing around with Python 3.12, discovering new features around typing and pattern matching. Combined with dataclasses, they provide support for a style of programming that I’ve employed in Kotlin and Typescript at work. That style in turn is based on what I’d do in OCaml or Haskell, like modelling data with algebraic data types. However, the more advanced concepts from Haskell —
As a reminder: Ruff is an extremely fast Python linter, written in Rust. Ruff can be used to replace Flake8 (plus dozens of plugins), isort, pydocstyle, pyupgrade, and more, all while executing tens or hundreds of times faster than any individual tool. Ruff is used in production by tens of thousands of open source projects and major enterprises. In the last year, we've been working to expand Ruff'
I’ve become convinced that “little languages”—small languages designed to solve very specific problems—are the future of programming, particularly after reading Gabriella Gonzalez’s The end of history for programming and watching Alan Kay’s Programming and Scaling talk. You should go check them out because they’re both excellent, but if you stick around I’ll explain just what I mean by “little lan
Introduction Before explaining why I created Oil, let's review what it is. You can think of a Unix shell in two ways: As a text-based user interface. You communicate with the operating system by typing commands. As a language. It has variables, functions, and loops. Shell programs are text files that start with #!/bin/sh. In this document, we'll think of Unix shells as languages. The Oil project a
Tier 4 Support § Support for these targets is entirely experimental. If this target is provided by LLVM, LLVM may have the target as an experimental target, which means that you need to use Zig-provided binaries for the target to be available, or build LLVM from source with special configure flags. zig targets will display the target if it is available. This target may be considered deprecated by
The diagram above is the compiler for the language Bolt we’ll be building. What do all the stages mean? I have to learn OCaml and C++? Wait I haven’t even heard of OCaml… Don’t worry. When I started this project 6 months ago, I had never built a compiler, nor had I used OCaml or C++ in any serious project. I’ll explain everything in due course. In this series of posts we’ll be building a proper pr

This article was discussed on Hacker News. This is a continuation of my last post on how to write a tree-sitter grammar in an afternoon. Building on the grammar we wrote, now we’re going to write a linter for Imp, and it’s even easier! The final result clocks in less than 60 SLOC and can be found here. Recall that tree-sitter is an incremental parser generator. That is, you give it a description o
Git as debugging tool
Are you sure? Debugging with Git? What are the tools that comes on your mind when someone say “debug”? Let me guess: a memory leak detector (e.g. Valgrind); a profiler (e.g. GNU gprof); a function that stops your program and gives you a REPL (e.g. Python’s breakpoint and Ruby’s byebug); something that we call a “debugger” (like GDB, or something similar embedded on the IDEs); or even our old frien
【目的別】コピペから始めるCython入門 ~はじめてのコンパイルから自作package化まで~ — HACK The Nikkei
データサイエンティスト(?)の青田です。これは Nikkei Advent Calendar 2021 の 25 日目の記事です。 はじめに 本記事では Cython を用いるときに発生しがちなつまずきポイントについて実用的な具体例を示す。つまずきポイントをほぼコピペで乗り越えられることを意識して執筆した。 すでに数多くのブログや公式ドキュメントがある中でこれを書いたモチベーションがある。 Cython はコンパイルしようとするだけでも 4 種類のやり方が存在し、型宣言の仕方は 3 種類の作法があり、numpy との連携方法は 2 種類存在する。 このように同じことをやろうとしたときの選択肢の多さが混乱を招いているように感じた。いろんな流派が存在するものの、ここでは自分の方法を目的別に示す。これにより、利用者の選択の時間を削減し、Cython を道具として使いやすくなるだろう。 本記事は以
I recently shipped Context, a native macOS app for debugging MCP servers. The goal was to build a useful developer tool that feels at home on the platform, powered by Apple's SwiftUI framework. I've been building software for the Mac since 2008, but this time was different: Context was almost 100% built by Claude Code1. There is still skill and iteration involved in helping Claude build software,
This year’s Advent of Code has been brutal (compare the stats of 2023 with that of 2022, especially day 1 part 1 vs. day 1 part 2). It included a problem to solve with dynamic programming as soon as day 12, which discouraged some people I know. This specific problem was particularly gnarly for Advent of Code, with multiple special cases to take into account, making it basically intractable if you
My LLM codegen workflow atm
tl:dr; Brainstorm spec, then plan a plan, then execute using LLM codegen. Discrete loops. Then magic. ✩₊˚.⋆☾⋆⁺₊✧ I have been building so many small products using LLMs. It has been fun, and useful. However, there are pitfalls that can waste so much time. A while back a friend asked me how I was using LLMs to write software. I thought “oh boy. how much time do you have!” and thus this post. (p.s. i
Hello friends, this is the first of two, possibly three (if and when I have time to finish the Windows research) writeups. We will start with targeting GNU/Linux systems with an RCE. As someone who’s directly involved in the CUPS project said: From a generic security point of view, a whole Linux system as it is nowadays is just an endless and hopeless mess of security holes waiting to be exploited
I’m a fairly frequent Hacker News lurker, especially when I have some other important task that I’m avoiding. I normally head to the Active page (lots of comments, good for procrastination) and pick a nice long discussion thread to browse. So over time I’ve ended up with a good sense of what topics come up a lot. “The Bay Area is too expensive.” “There are too many JavaScript frameworks.” “Bootcam
From my perspective, one of the biggest open problems in implementing programming languages is how to add a type system to the language without significantly complicating the implementation. For example, in my tutorial Fall-from-Grace implementation the type checker logic accounts for over half of the code. In the following lines of code report I’ve highlighted the modules responsible for type-che
I recently came to a good stopping spot on an ambitious project to build a B+ Tree library using augmented coding. The result is BPlusTree3 - a performance-competitive, maybe-production-ready implementation in Rust & Python. I sat down with a friend to tell my story and reflect on what it reveals about the future of programming in the GenAI era. If you want to support my work, join a community wor
TIL: eBPF is awesome
A blog about programming, technology and open-source stuff. I was doing some research at work for tracing and observability for microservices, when I came across Pixielabs. This tool advertises that you can instantly troubleshoot applications without any instrumentation or special code inside the apps, which sounded ✨magical✨ to me. So naturally I wanted to know a little more about what enables th
