Firefox Quantum
Next week, Mozilla will release Firefox 57. Also referred to as Firefox Quantum, from the project name we've used for all the work that has been put into making this the most awesome Firefox release ever. This is underscored by the fact that I've gotten mailed release-swag for the first time during my four years ……

Sick of Ruby, dynamic typing, side effects, and object-orientation (2014)
This has been a long time coming. I had meant to write this post around the New Year, before the wave of death of Ruby stuff and before DHH’s “ TDD is dead ” ruckus:

Self-Replicating Functions
These are notes I’m creating for myself as I explore functions \(f\) that can be written as a sum \(f = g_1 + g_2\) where \(g_1\) and \(g_2\) are shifted and possibly reflected versions of each other, both strongly resembling the original function \(f\) . When a function \(f\) has these properties, I informally call…

Render Multimedia in Pure C
In a previous article I demonstrated video filtering with C and a unix pipeline . Thanks to the ubiquitous support for the ridiculously simple Netpbm formats — specifically the “Portable PixMap” ( .ppm , P6 ) binary format — it’s trivial to parse and produce image data in any language without image libraries. Video…

Command line interfaces are reified UIs

Linux containers in 500 lines of code (2016)
I've used Linux containers directly and indirectly for years, but I wanted to become more familiar with them. So I wrote some code. This used to be 500 lines of code, I swear, but I've revised it some since publishing; I've ended up with about 70 lines more.

Chuck Moore, Extreme Programmer
If you have read any of Chuck Moore's work, you know that he is an extreme programmer in the literal sense of the word: a unique philosophy that embraces small, fast, self-contained programs in a spare language and an impressive development environment. But as I read the opening sections of Moore's book Programming a…

An Introduction to Deep Learning for Language Modeling
Language models assign probability values to sequences of words. Those three words that appear right above your keyboard on your phone that try to predict the next word you’ll type are one of the uses of language modeling. In the case shown below, the language model is predicting that “from”, “on” and “it” have a high…

Why TDD isn't crap
After my recent vitriol about unit testing, a couple of people sent me Why TDD is Crap as a thorough debunking of TDD and unit testing. As someone very interested in software correctness, I ended up writing a debunking of his debunking. Transcriptions will be in quotes, my responses below. Some important notes: From…

Implementing VisiCalc (2003)
I'm writing this in preparation for the Computer History Museum's The Origins and Impact of VisiCalc panel on April 8th 2003. This is basically a draft and I hope to do some more editing as time permits and you should expect many typos until then. I'm also going to continue to edit and change this as I remember…

How to write a JavaScript-free todo app using just HTML and CSS

Crafting Interpreters: Classes
One has no right to love or hate anything if one has not acquired a thorough knowledge of its nature. Great love springs from great knowledge of the beloved object, and if you know it but little you will be able to love it only a little or not at all.

Language Models, Word2Vec, and Efficient Softmax Approximations
The Word2Vec model has become a standard method for representing words as dense vectors. This is typically done as a preprocessing step, after which the learned vectors are fed into a discriminative model (typically an RNN) to generate predictions such as movie review sentiment, do machine translation, or even…
