One of the key elements of Google's software engineering culture is the use of design docs for defining software designs. These are relatively informal documents that the primary author or authors of a software system or application create before they embark on the coding project. The design doc documents the high level implementation strategy and key design decisions with emphasis on the trade-of
On the 11th of January 1982 twenty-two computer scientists met to discuss an issue with ‘computer mail’ (now known as email). Attendees included the guy who would create Sun Microsystems, the guy who made Zork, the NTP guy, and the guy who convinced the government to pay for Unix. The problem was simple: there were 455 hosts on the ARPANET and the situation was getting out of control. This issue w

Secrets from the Algorithm: Google Search’s Internal Engineering Documentation Has Leaked
Google, if you’re reading this, it’s too late. Ok. Cracks knuckles. Let’s get right to it. Internal documentation for Google Search’s Content Warehouse API has leaked. Google’s internal microservices appear to mirror what Google Cloud Platform offers and the internal version of documentation for the deprecated Document AI Warehouse was accidentally published publicly to a code repository for the c
Consider SQLite
If you were creating a web app from scratch today, what database would you use? Probably the most frequent answer I see to this is Postgres, although there are a wide range of common answers: MySQL, MariaDB, Microsoft SQL Server, MongoDB, etc. Today I want you to consider: what if SQLite would do just fine? For those who are unfamiliar, SQLite is a implementation of SQL as a library — this means t

Today we’re excited to announce the release of TypeScript 5.0! This release brings many new features, while aiming to make TypeScript smaller, simpler, and faster. We’ve implemented the new decorators standard, added functionality to better support ESM projects in Node and bundlers, provided new ways for library authors to control generic inference, expanded our JSDoc functionality, simplified con

Best Rust Web Frameworks to Use in 2023 In the dynamic landscape of web development, Rust has emerged as a language of choice for building safe and performant applications. As Rust's popularity grows, so does the array of web frameworks designed to harness its strengths. This article compares some of the best Rust frameworks highlighting their respective advantages and drawbacks to help you make i
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-
The npm blog has been discontinued. Updates from the npm team are now published on the GitHub Blog and the GitHub Changelog. tl;dr – Good news! npm, Inc., is being purchased by GitHub. The public registry remains public, free, and as available as ever. npm as you know it continues, and in fact, there is good reason to believe that it’ll only get better. I’m still going to be working on npm (but wi

Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the
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
Published: August 4, 2023 Updated: October 27, 2023 Part 1: an intro about music, defaults, and bubbles Like a lot of people, there was a time when the only music I listened to was whatever was played on my local radio station. (A lot of people over 30 or so, anyway. If this doesn’t sound familiar to you yet, just stick with me for a minute here.) At the time, I was happy with that. It seemed like
When I started my career in development, my first job was a DBA. Back then, before AWS RDS, Azure, Google Cloud and the rest of them cloud services, there were two types of DBAs: The Infrastructure DBA was in charge of setting up the database, configuring the storage and taking care of backups and replication. After setting up the database, the infrastructure DBA would pop up from time to time and
Earlier today, Airbnb Co-Founder and CEO Brian Chesky sent the following note to Airbnb employees. This is my seventh time talking to you from my house. Each time we’ve talked, I’ve shared good news and bad news, but today I have to share some very sad news. When you’ve asked me about layoffs, I’ve said that nothing is off the table. Today, I must confirm that we are reducing the size of the Airbn
One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m

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

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

In this guide (the first in a three-part series), we’ll cover some of the most common use-cases for AWS tags a
Operating a Large, Distributed System in a Reliable Way: Practices I Learned
For the past few years, I've been building and operating a large distributed system: the payments system at Uber. I've learned a lot about distributed architecture concepts during this time and seen first-hand how high-load and high-availability systems are challenging not just to build, but to operate as well. Building the system itself is a fun job. Planning how the system will handle 10x/100x t
Show navigation Writing a high-performance JavaScript engine takes more than just having a highly optimising compiler like TurboFan. Particularly for short-lived sessions, like loading websites or command line tools, there’s a lot of work that happens before the optimising compiler even has a chance to start optimising, let alone having time to generate the optimised code. This is the reason why,
Modern source-control systems provide powerful tools that make it easy to create branches in source code. But eventually these branches have to be merged back together, and many teams spend an inordinate amount of time coping with their tangled thicket of branches. There are several patterns that can allow teams to use branching effectively, concentrating around integrating the work of multiple de

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
