Easily the biggest question we get asked is something like: How is Remix different from Next.js? It appears we have to answer this question! We'd like to address it directly and without drama. If you're a fan of Remix and want to start tweeting smug reactions to this article, we kindly ask that you drop the smugness before hitting the tweet button 🤗. A rising tide lifts all boats.

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
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 few examples is goo
How NAT traversal works
* can theoretically exist, but don't show up in the wild Once broken down like this, we can see that cone-ness isn’t terribly useful to us. The major distinction we care about is Symmetric versus anything else — in other words, we care about whether a NAT device is EIM or EDM. While it’s neat to know exactly how your firewall behaves, we don’t care from the point of view of writing NAT traversal c
I joined GitLab in October 2015, and left in December 2021 after working there for a little more than six years. While I previously wrote about leaving GitLab to work on Inko, I never discussed what it was like working for GitLab between 2015 and 2021. There are two reasons for this: I was suffering from burnout, and didn't have the energy to revisit the last six years of my life (at that time)I w
Hello! I’m slowly working on explaining git. One of my biggest problems is that after almost 15 years of using git, I’ve become very used to git’s idiosyncracies and it’s easy for me to forget what’s confusing about it. So I asked people on Mastodon: what git jargon do you find confusing? thinking of writing a blog post that explains some of git’s weirder terminology: “detached HEAD state”, “fast-
Parse, don’t validate
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process that doesn’t require plucking the “right” approach out of thin air—yet I haven’t bee
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 training neural networks. This implementation is missing tons of features on purpose to keep it as simple as p
Speculation in JavaScriptCore
This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine. Speculative compilation is ideal for making dynamic languages, or any language with enough dynamic features, run faster. In this post, we will look at speculation for JavaScript. Historically, this technique or closely related variants has been applied successfully t
In this post I will hopefully detail my entire home network. Some of this has been in separate posts explaining single items, but nowhere do I have all of the network in one post with all the changes since last year. Here is a full shot of the rack in my house. Its in a centrally located closet which happens to have a 2ft x 2ft chase into the attic, which is very handy for running network cables.
(There is good discussion on this article on Hacker News and Reddit) Reddit is currently the most popular search engine. The only people who don’t know that are the team at Reddit, who can’t be bothered to build a decent search interface. So instead we resort to using Google, and appending the word “reddit” to the end of our queries. Paul Graham thinks this image means Reddit as a social media sit

Remove Richard Stallman
Edited on 03/22/2021: If you are reading this in 2021, it is likely because Stallman has been reinstated as a board member of the free software foundation. Since news like that always comes with renewed interest in this blog post, rather than suffering the litany of responses nitpicking at words that have already started pouring in, I encourage you to instead (or at least in addition) read “Append
I've found that one of the best ways to understand a new concept is to start from the very beginning. Start from a place where it doesn't exist yet and recreate it yourself, learning in the process not just how it works, but why it was designed the way it was. This isn't a practical guide to async, but hopefully some of the background knowledge it covers will help you think about asynchronous prob
Despite the click-bait title I hope you'll find this post generally illuminating, or at the very least a bit of fun! This article makes no claims that Haskell is "better" than C, nor does it make claims about the respective value of either language, or either implementation. It's simply an exploration into high-performance Haskell, with a few fun tricks and hacks along the way. You can find source
I first got into web design/development in the late 90s, and only as I type this sentence do I realize how long ago that was. And boy, it was horrendous. I mean, being able to make stuff and put it online where other people could see it was pretty slick, but we did not have very much to work with. I’ve been taking for granted that most folks doing web stuff still remember those days, or at least t

Deno is a Browser for Code
I started contributing to Deno soon after Ry made the prototype visible in May 2018. The most frequent question that people have is "where is the package manager?" which often times isn't even in the form of a question. It is statements like "I thought Deno took security seriously, and just downloading resources off the internet is insecure." or "How can I possibly manage my dependencies?" In my o

What happened to Vivaldi Social? | Thomas Pike’s other blog
On Saturday 8 July 2023, user accounts started disappearing from the Vivaldi Social Mastodon instance. What was going on, how did this happen, and what were the consequences? This is a very long blog post, but to be fair, this was also to be a very long weekend. If you want to skip to the conclusion, there’s a TL;DR (too long; didn’t read) section at the end.

Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t
