Shadertoy is a wonderful tool which lets users create and share a type of program called a fragment shader online. The true magic of shadertoy is its community of very talented graphics programmers who build incredible works of art despite having access to only a sliver of the traditional graphics pipeline.
F is a pure functional concatenative language originally designed as an extension of False . F contains the list-operations of K3 and the dip combinator of Joy . Floating-point and symbolic datatypes are supported. One-time assignment is enforced in syntax. A theory of function-valence and -charge is outlined. F also…
Who framed Roger Rabbit? Talking about Software Development is about using frames. The prevalent "Backlog" frame is bad for the company and bad for developers.
There are too many packages and too many dependencies, too deeply nested. Can we measure the problem? And what do we do about it?
Well, the title says it all!
I’ve been learning Rust for the past twenty days or so, working through the Blandy & Orendorff book, coding up things as I go. Once I got into playing with Rust traits and closures and as…
Searching for the best legally free Python books can be overwhelming with so many broken links and outdated resources. This curated list provides over 80 high-q...
...and the crucial role it plays in modern operating systems.
Django is currently the most commonly used full-stack web framework for Python. It has been around for a good 15 years, emerging as a winner from a period in which Python was already mature, but its web development tools were comparatively much more immature and fragmented.
Towards an API for the real numbers, Boehm, PLDI’20 Last time out we saw that even in scientific computing applications built by experts, problems with floating point numbers are commonplace. …

Threat modeling is a risk based approach to cyber security requirements analysis.
Code says what it does. That’s important for the computer, because code is the way that we ask the computer to do something. It’s OK for humans, as long as we never have to modify or debug the code. As soon as we do, we have a problem. Fundamentally, debugging is an exercise in changing what a program does to match…
I recently became intrigued by the concept of event sourcing as applied to back-end architecture, specifically a microservice-oriented approach. I have spent the last few years working predominantly on the front-end, and became enamored by the simplicity and elegance of this pattern as the backbone of front-end…
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 sole purpose of this blog is to host a single article..

About two years ago, I wrote a quite complicated diff tool in Clojure. It was complicated enough that I struggled to fit the algorithm in my head and the inputs were large enough that I had to make some efforts to improve performance.
This is a quick writeup of a steganographic tool that I threw together: steg86 . It uses a quirk of the x86 instruction encoding format to hide messages in pre-existing binaries with no size or performance overhead.
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).
An appropriately annoying strategy for dealing with wiki rot at a company.
How inappropriate data access patterns massively slow down programs and how the same problems arise with RESTful APIs.
Late last year I released posuto, a package presenting Japanese postal code data in an easy-to-use format. It's based on data released by Japan Post, which is infamous for being widely used but hard to parse.
