Another year passes. I was hoping to write more articles instead of just these end-of-the-year screeds, but I almost died in the spring semester, and it sucked up my time. Nevertheless, I will go through what I think are the major trends and happenings in databases over the last year. There were many exciting and unprecedented developments in the world of databases.

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

How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru
How we built the Grafbase local development experience in Rust
How we built the Grafbase local development experience in Rust Grafbase provides an edge-native GraphQL platform that combines multiple data-sources into a single API and includes a serverless database, search, edge caching, preview environments and much more. Around May 2022 we started working on a local development experience, written in Rust, to mirror this functionality locally and allow you t

Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen. The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However
KDL is a small, pleasant document language with XML-like node semantics that looks like you're invoking a bunch of CLI commands! It's meant to be used both as a serialization format and a configuration language, much like JSON, YAML, or XML. It looks like this: package { name my-pkg version "1.2.3" dependencies { // Nodes can have standalone values as well as // key/value pairs. lodash "^3.2.1" op

In this blog post we benchmark many Ruby versions and the latest Ruby Just-in-Time compilers (JITs) on the newest Ruby benchmark suite, yjit-bench. As a teaser, the geometric mean speedups compared to CRuby 3.1 on these 14 benchmarks are: MJIT 1.26x, YJIT 1.39x, JRuby 1.86x and TruffleRuby 6.23x. Read on to find more about the benchmarks and gain insights on these speedups. This blog post is also

A new JavaScript backend was merged into GHC on November 30th, 2022! This means that the next release of GHC will be able to emit code that runs in web browsers without requiring any extra tools, enabling Haskell for both front-end and back-end web applications. In this post, we, the GHC DevX team at IOG, describe the challenges we faced bringing GHCJS to GHC, how we overcame those challenges, and

Introduction A floating point number f has the form f=m·2e where m is called the mantissa and e is a signed integer exponent. We like to read numbers scaled by powers of ten, not two, so computers need algorithms to convert binary floating-point to and from decimal text. My 2011 post “Floating Point to Decimal Conversion is Easy” argued that these conversions can be simple as long as you don’t car

Proto Best Practices
Clients and servers are never updated at exactly the same time - even when you try to update them at the same time. One or the other may get rolled back. Don’t assume that you can make a breaking change and it’ll be okay because the client and server are in sync. Don’t Re-use a Tag NumberNever re-use a tag number. It messes up deserialization. Even if you think no one is using the field, don’t re-
