REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with
January 30, 2023 In this post, we'll implement a GPT from scratch in just 60 lines of numpy. We'll then load the trained GPT-2 model weights released by OpenAI into our implementation and generate some text. Note: This post assumes familiarity with Python, NumPy, and some basic experience with neural networks. This implementation is for educational purposes, so it's missing lots of features/improv
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

CUPID: for joyful coding
What started as lighthearted iconoclasm, poking at the bear of SOLID, has developed into something more concrete and tangible. If I do not think the SOLID principles are useful these days, then what would I replace them with? Can any set of principles hold for all software? What do we even mean by principles? I believe that there are properties or characteristics of software that make it a joy to

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.

If you combine this with the Unicode table, you’ll see that English is encoded with 1 byte, Cyrillic, Latin European languages, Hebrew and Arabic need 2, and Chinese, Japanese, Korean, other Asian languages, and Emoji need 3 or 4. A few important points here: First, UTF-8 is byte-compatible with ASCII. The code points 0..127, the former ASCII, are encoded with one byte, and it’s the same exact byt
Delimiter-first code
Summary I argue for wider usage of delimiter-first in the code three friends [tic, tac, toe] becomes three friends ・tic ・tac ・toe. A new top-level syntax for programming languages is proposed to show advantages of this method. New syntax is arguably as simple, but more consistent, better preserves visual structure and solves some issues in code formatting. Related: comma-first formatting A well-kn

It is December. That means annoying Christmas things are everywhere, including but not limited to the annual programming semi-competition known as Advent of Code. The problem with Advent of Code is that it is a waste of time. Most of the puzzles are in the realm of either string processing (somewhat applicable to programming), logic puzzles (not really applicable to most programming), or stupid go
The Go Programming Language and Environment – Communications of the ACM
Go is a programming language created at Google in late 2007 and released as open source in November 2009. Since then, it has operated as a public project, with contributions from thousands of individuals and dozens of companies. Go has become a popular language for building cloud infrastructure: Docker, a Linux container manager, and Kubernetes, a container deployment system, are core cloud techno

はじめに 初めまして、株式会社Carnotでインターンをしている長谷川と申します。 Carnotでは、LLMを活用し日々の業務フローの効率化や自動化をするためのソリューション「Promptflow」の開発を行っています。 上記のようなワークフローを作成する際には、SlackやGmail、Notionなど各サービスのAPIを連携させていく必要があります。しかし、そのような開発にはプログラミングの知識が必須で、非エンジニアにとってAPIを用いたシステムを作成することは難しいと思われます。そこで、今回は言語のみの指示から複数のAPIを呼び出すことが可能なRestGPTという手法を調査しました。 例えば音楽配信サービスを使う中で「YOASOBIが出した最新のアルバムを自分のプレイリストに追加する」という作業をしたい時、これを自分で行うのは面倒である上、コードを書いて自動化するのも非エンジニアにとっ

Let’s Write a Tree-Sitter Major Mode Creating a standard programming major mode presents significant challenges, with the intricate tasks of establishing proper indentation and font highlighting being among the two hardest things to get right. It's painstaking work, and it'll quickly descend into a brawl between the font lock engine and your desire for correctness. Tree-sitter makes writing many m
I did this in 2020 and then again in 2021, but I’m in the mood to look around again. Let’s look through Are We GUI Yet? and see what’s up these days. The task today is to have a text label and an input field that can change the text in the label. In React, for example, this is basically free: const Demo = () => { let [state, setState] = useState("Hello, world!"); return ( <div> <p>{state}</p> <inp

For almost a complete decade—starting with discovering Haskell in about 2009 and right up until switching to a job where I used primarily Ruby and C++ in about 2019—I would have called myself first and foremost a Haskell programmer.

Revenge of Lisp (Part 1⁄2) Background vector created by upklyak - www.freepik.com This may surprise you if you know me, but I’ve been learning Common Lisp for a few weeks now. It all started when I was reading, funnily enough, a blog post about another, much more hyped, language called Julia. The post was titled Julia and the reincarnation of Lisp, and in it the author lamented that despite his lo

Packing up the household for a recent move, I was delving into shoeboxes, photo albums, and file folders that had not been opened in decades. One of my discoveries, found in an envelope at the back of a file drawer, was the paper sleeve from a drinking straw, imprinted with a saccharine message: This flimsy slip of paper seems like an odd scrap to preserve for the ages, but when I pulled it out of

Amongst the many consequences of COVID-19 has been the suspension of in-person talks: suddenly, people like me have had to think about how to produce prerecorded videos. In this article I’m going to explain what I’ve come to understand about video recording and the “automatic video editing” technique I’ve used for videos such as Virtual Machine Warmup Blows Hot and Cold. To give you an idea of how
Introduction: Density Is King (With a Tiny VM) I've previously come to the conclusion that there's little reason for using bytecode in the modern world, except in order to get more compact code, for which it can be very effective. So, what kind of a bytecode engine will give you more compact code? Suppose I want a bytecode interpreter for a very small programming environment, specifically to minim

I’ll guarantee it by including 2 novel tracing tools I’ve made and haven’t shared before (loo
In this write-up, I will walk you through an implementation of a string formatting library for C++ I came up with for my video game.

Usage Given a format buffer… char buffer[64]; String_Buffer buf = {str, sizeof str}; …the fmt::format function pr
Python behind the scenes #11: how the Python import system works
If you ask me to name the most misunderstood aspect of Python, I will answer without a second thought: the Python import system. Just remember how many times you used relative imports and got something like ImportError: attempted relative import with no known parent package; or tried to figure out how to structure a project so that all the imports work correctly; or hacked sys.path when you couldn
