SQL needed structure
The data on the page is presented in a hierarchichal structure. The movie page contains a director, a list of genres, a list of actors, and each actor in the list contains a list of characters they played in the movie. You can't sensibly fit all of this into a single flat structure like a relation.

Modular monolith and microservices: Modularity is what matters
Modularity is a crucial concept when designing and creating software. Independent of whether our chosen architecture style is to have a single unit of deployment - Monolith or multiple units of deployment - Microservices/Services. It is a quality that should be treated completely independent of how many deployable…

Gradle still sucks
I wrote a blog post a while ago complaining about Gradle, mostly from a position of ignorance: I had never really taken the time to properly learn the tool and I was frustrated while trying to stumble my way through working with it. But luckily, my company encourages learning and experimentation so I was given an…

Which is better on Android: divide by 2 or shift by 1?
I've been porting the AndroidX collection library to Kotlin multiplatform to experiment with binary compatibility, performance, tooling, and the different memory models. Some of the data structures in the library use array-based binary trees to store elements. The Java code has a lot of shifts to replace power-of-two…

PageRank explained
Picture this, the year is 1996. You find yourself frustrated with the incumbent search engines like AltaVista, which primarily does a content-based search (it'll give you an article on "Hotels for Chickens" if you search "Hotels" because the word matches). There's gotta be a better way, right? Well, in hindsight, of…

Say “no” to import side‐effects in Python
When you write Python code, please make sure that you don’t have side‐effects in your module imports. It breaks things and makes people sad.

How to Fit a Large Program into a Small Machine (1999)
As a rule, "sophisticated" progrmming is pretty boring - optimizing the unnecessary to speed up the uninteresting. Here, however, is an incredibly sophisticated package intended for fun and games. The more you know about software, the more astounded you will become as you read this.

My Ideal Array Language
The fundamental units of computation available to users today are not the same as they were 20 years ago. When users had at most a few cores on a single CPU, it made complete sense that every program was written with the assumption that it would only run on a single core.

Intrusive lists in Doom 3
Doom 3 was released in 2004, which I can't believe was a decade ago. Great game, atmospheric and scary, and a worthy successor of the first two games in the series. Several years after the initial release, in 2011, Doom 3's source code was published on Github. It can be fun to poke around the repository to learn how…

Enforcement by Software
At my university, one of our internal software systems allows a professor to submit a revision to a course. The professor might change the content or the objectives of the course. In a university, professors have extensive freedom regarding course content. As long as you reasonably meet the course objectives, you can…
