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
Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

Vjeux » Birth of Prettier
React Conf is around the corner and it's been almost 10 years since Prettier was released. I figured it would be a good time to recount the journey from its early days to now. This is the story of how the "Space vs Tabs Holy War" ended, not through one side winning over the other but instead a technological invention making it the underlying source of tensions no longer being a thing. Back Story S
Introduction 11 May 2021 — This website presents FragAttacks (fragmentation and aggregation attacks) which is a collection of new security vulnerabilities that affect Wi-Fi devices. An adversary that is within range of a victim's Wi-Fi network can abuse these vulnerabilities to steal user information or attack devices. Three of the discovered vulnerabilities are design flaws in the Wi-Fi standard

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what th
I thought it would be fun to go outside of my comfort zone of web development topics and write about something completely different and new, something I have never written about before. So today, I'm going to show you how to implement a programming language! The project will parse and execute programs written in a simple language I called my (I know it's a lame name, but hey, it is "my" language).

*if you include word2vec. Chris and I spent a couple hours the other day creating a search engine for my blog from “scratch”. Mostly he walked me through it because I only vaguely knew what word2vec was before this experiment. The search engine we made is built on word embeddings.

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

はじめての自然言語処理 Sentence Transformer による文章ベクトル化の検証 | オブジェクトの広場
今回は文章のベクトル化を扱います。文章のベクトル化は 第9回 で扱っていますが、当時に比べてデータセット、事前学習モデル、ライブラリ等でいろいろと状況が好転しているので、改めて扱ってみることにしました。最近は大規模データセットを用いた事前学習が公開されているので、作り比べてみます。 1. はじめに 今回は sentence-transformers1 で文章のベクトル化にチャレンジしてみます。文章をベクトル（埋め込み表現）化することで、文章間の意味合い的な比較が可能になり、類似文章検索やクラスタリングなどが可能になります。 このライブラリは 第9回 で紹介済みですが、当時のバージョンは 0.2.5.1 であり、その後に損失関数が追加されていたり、サンプルコードが充実したりとかなりの更新が入って執筆時点で 2.1.0 になっています。ついでに言うと 第9回 は結構アクセス数があるみたいなので
In 2006 Microsoft conducted a customer survey to find what new features users want in new versions of Microsoft Office. To their surprise, more than 90% of what users asked for already existed, they just didn't know about it. To address the "discoverability" issue, they came up with the "Ribbon UI" that we know from Microsoft Office products today. Office is not unique in this sense. Most of us ar
Explicit Resource Management: Exploring JavaScript's and TypeScript's new feature | iliazeus
One of my favorite new features of JavaScript and TypeScript is explicit resource management. It brings new syntax, using foobar = ..., that enables RAII, reducing boilerplate when managing the lifecycle of various resources. In this article, I will explore this feature as implemented in TypeScript 5.2.0 with the disposablestack polyfill. I will mention both sync and async resources, DisposableSta

iOS Hacking - A Beginner’s Guide to Hacking iOS Apps [2022 Edition]

I will also be using ‘checkra1n’ for the device jailbreak

You must know the power of Object-oriented programming if you have ever worked with object-oriented languages like Java, C#, and much more. Python also supports object-oriented programming, and we can define a class in Python. Let’s explore more about how to achieve this in Python. In the post Getting Started with Python, I have covered the essentials required before becoming a data scientist. In
The simplicity of Prolog
Back to homepage Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are all imperative (and for the most part object-oriented) languages,

Julia 1.0 came out well over 2 years ago. Since then a lot has changed and a lot hasn’t. Julia 1.0 was a commitment to no breaking changes, but that is not to say no new features have been added to the language. Julia 1.6 is a huge release and it is coming out relatively soon. RC-1 was released recently. I suspect we have at least a few more weeks before the final release. The Julia Core team take
While getting my degree in Physics, I had to take classes in both MatLab and Python for scientific computing. I preferred python, where we used the SciPy and NumPy packages. In fact, I used those packages again (along with matplotlib) in an undergraduate research project simulating bacteria films. There's a catch: I was also pursuing a degree in Computer Science, and Python just wasn't fast enough
Hash functions are incredibly neat mathematical objects. They can map arbitrary data to a small fixed-size output domain such that the mapping is deterministic, yet appears to be random. This “deterministic randomness” is incredibly useful for a variety of purposes, such as hash tables, checksums, monte carlo algorithms, communication-less distributed algorithms, etc, the list goes on. In this art

The Pitchfork Story
A bit more than two years ago, as part of my work in Shopify’s Ruby and Rails Infrastructure team, I released a new Ruby HTTP server called Pitchfork.

Unicorn’s Design Is Fine Ever since I joined Shopify over 11 years ago, the main

Python behind the scenes #6: how Python object system works
As we know from the previous parts of this series, the execution of a Python program consists of two major steps: The CPython compiler translates Python code to bytecode. The CPython VM executes the bytecode. We've been focusing on the second step for quite a while. In part 4 we've looked at the evaluation loop, a place where Python bytecode gets executed. And in part 5 we've studied how the VM ex
