Over time, a system collects state on its root partition. This state lives in assorted directories like /etc and /var , and represents every under-documented or out-of-order step in bringing up the services.
Did you know there’s an algebraic structure for functions? That may not surprise you at all. But it surprised me when I first found out about it. I knew we used functions to build algebraic structures. It never occurred to me that functions themselves might have an algebraic structure. The structure is fascinating…
Gosper's Glider Gun in Conway's Game of Life I'd known of Conway since my early teens. I remember reading about his Game of Life in an old Scientific American someone gave me. The article (a quick search tells me) was published in October 1970, so I'm guessing I saw it in the early 70s, perhaps 1972. I was hooked.
Writing a SQL database from scratch in Go: 1. SELECT, INSERT, CREATE and a REPL
Programming language performance is something that nearly everyone cares about at some point, whether they realise it or not. If you’re a programmer, you sometimes have to make your programs run fast; if you’re a user, you might be frustrated at a program that runs slowly, without knowing that it’s caused by a poor…
Computers and computer systems are build up from deterministic, comprehensible, building blocks. Their operations and behaviors can be understood and reasoned about. I relate my personal beliefs and mindset on this point, and explore some manifestations and ramifications of this philosophy.
The rules of logic no longer apply when you cross the line.
Using Java or Python in a professional IDE like IntelliJ IDEA, NetBeans, PyCharm, or Eclipse is not a good first introduction to programming for computer science students, whether they’re in the field to become web developers, systems software engineers, or academic computer science researchers.
How do I synchronize application data between devices and people? That's the question I was unable to answer when thinking about ideas for new applications I could develop. I wanted the synchronization to be
Shopify's involvement with TruffleRuby began half a year ago, with the goal of furthering the success of the project and Ruby community. TruffleRuby is an alternative implementation of the Ruby language (where the reference implementation is CRuby, or MRI) developed by Oracle Labs. TruffleRuby has high potential in…
Gavin Sherry and I have presented several versions of a tutorial introduction on how to modify the PostgreSQL source code. The original version was given at the PostgreSQL Anniversary Summit in June of 2006. Gavin has since given a revised version of the talk (at LCA 2007), as have I (at PgCon 2007).
From a confusing page of old C code to APL/J praise.
A recent tweet by a friend of mine noted how the public interest in the Scala programming language seems to have plateaued or waned, which matches my feeling of the latest trends and zeitgeist. This blog post will go into why I think that has happened, where Scala stands now, and what the future holds for the Scala…
Find out how a single JS package can come with 19k dependencies.
Everyone knows that Java is slow and Clojure is not a great choice for number crunching, but as soon as I dig anywhere with my software, I discover that the ...
Why I can't use Elm, and can't recommend it to others.
Google's plans on making Swift the first mainstream language with first-class language-integrated differentiable programming capabilities. What's so cool about Swift?
Recently withoutboats posted a series of blog posts about some syntax sugar he would like added to Rust.
