The IDE as a value
In my last post I talked about building a game in ClojureScript using a Component-Entity-System engine and I hinted that the ideas that underly that architecture inspired how we designed Light Table . The reason why stems from the architectural goals of the project:

Emacs Tramp over AWS SSM APIs
Cattle not pets The majority of AWS EC2 I need to operate these days are members of Kubernetes clusters. For remote access to them I’m more commonly authenticating to the Kube API to spawn a privileged ephemeral debugger pod rather than accessing the host directly. I have little need for host access even for the…

Object-Oriented Programming and Essential State
Back in 2015, Brian Will wrote a provocative blog post: Object-Oriented Programming: A Disaster Story . He followed it up with a video called Object-Oriented Programming is Bad , which is much more detailed. I recommend taking the time to watch the video, but here’s my one-paragraph summary:

Introducing "Functional JavaScript"
A few years ago I got the idea that it would be fun to implement a variant of Scheme targeting the JVM. During my search for different ways to implement numerics I looked deeply at the implementation of two languages: JScheme and a little-known language Clojure . During my explorations with these two languages and the…

The Musl Preprocessor Debate
Today, I would like to discuss a project that I care very deeply about: the musl libc. One of the most controversial and long-standing debates in the musl community is that musl does not define a p…

Starting data analysis with R: Things I wish I'd been told
R is a very powerful open source environment for data analysis, statistics and graphing, with thousands of packages available. After my previous blog post about likert-scales and metadata in R , a few of my colleagues mentioned that they were learning R through a Coursera course on data analysis . I have been working…

When code is suspiciously fast: adventures in dead code elimination
Part of a recent assignment for one of my classes involved calculating the Fibonacci sequence both recursively and iteratively and measuring the speed of each method. (BONUS: For a fun diversion, here is a paper I wrote about using the Golden Ratio, which is closely related to the Fibonacci sequence, as a base for a…

Higher quality random floats
Much has been written about how to generate random 64-bit integers; people might argue over which particular (CS)PRNG is best suited for a given task, but there is agreement on the general shape of the solution: keep some state around, and then extract 64 bits of randomness at a time, where each bit is equally likely…

Building a 64-bit aarch64 kernel and userspace for the Raspberry Pi 4
I’ve recently been tinkering around with using a Raspberry Pi as a desktop computer. The Pi 4 is fairly powerful; very sufficient for web browsing, audio, video, and terminal use for programming.

Avoiding Instruction Cache Misses
Excessive instruction cache misses are the kind of a performance problem that's going to appear only in larger codebases. In this article, I'm describing some ideas on how to deal with this issue.

Avoiding Reflection (And Such) in Go
So, as previous posts show , I like Go well enough. But as a computer-language polyglot, "Go programmer" is not part of my identity, and I try for a balanced view. It is very human to go overboard in both praise and criticism, both easy to find online.

Threads (in Ruby): Enough Already
For a while now, the Ruby community has become enamored in the latest new hotness, evented programming and Node.js. It's gone so far that I've heard a number of prominent Rubyists saying that JavaScript and Node.js are the only sane way to handle a number of
