Technical Time Travel: On Vintage Programming Books

A look at three relics of a not-quite-bygone era. In picture-listicle form. As technologists, we’re constantly gulping from the bleeding-edge firehose: new versions, new standards, new frameworks, new paradigms. This is largely a good thing. Most advances offer a tangible improvement over the status quo. Specialization (e.g. recent Bachelors Degrees in AI) speeds the advanceContinue reading “Technical Time Travel: On Vintage Programming Books”


Type Polymorphic Functions In TypeScript

JavaScript allows functions to work flexibly when the arguments passed are of different types and/or at different positions: The useState Hook lets you pass an initial value or a function for lazy initialization, or you can skip it altogether and pass nothing to it. The query API from node-postgres accepts an optional callback function andContinue reading “Type Polymorphic Functions In TypeScript”

Strype, a frame-based editor

Frame-based editing combines the benefits of text-based editing and block-based editing. It offers similar avoidance of syntax errors and discoverability as block-based systems, while providing readability and flexibility of editing similar to text editors. Python-like programs are written by inserting frames, using a single key command, which represent a complete statement in the language. NoContinue reading “Strype, a frame-based editor”

Writing a device driver for Unix V6

In this post we will learn the useful skill of writing a device driver for Unix V6 (released in 1975) and run it on an emulator. The implemented device is fairly trivial: it will open a message box on the host OS. The goal is that we can execute the following command:echo “Hello world” >Continue reading “Writing a device driver for Unix V6”

How to design better APIs

15 language-agnostic, actionable tips on REST API design. APIs are awesome, but they’re also extremely hard to design. When creating an API from scratch, you need to get many details right. From basic security considerations to using the right HTTP methods, implementing authentication, deciding which requests and responses you should accept and return, … theContinue reading “How to design better APIs”
