TLA, the Temporal Logic of Actions is the core of TLA+. It is a temporal logic that minimizes the use of temporal reasoning in favor of more ordinary mathematics. It is a general mathematical framework for describing and reasoning about algorithms and systems.
When the textile industry arose in the 18th century, craft was the norm in manufacturing. As the industrial revolution progressed, one after another sector of the economy made the transition from c…
You can use of UUIDs as the primary key to avoid database scale problems. But should you? I propose an alternative.
Peter Bourgon has a web site, and this is that web site.
I made a new years resolution to read at least one C source file from OpenBSD daily.The goal was to both get better at C and to contribute more to the base s...
If you think this is easy, then I think you are missing something. This is hard. You need to know your hardware intimately to figure this one out.
A massive amount of reporting queries, whether really intensive data analysis, or just basic insights into your business involving looking at data over a certain time period. Postgres has really rich support for dealing with time out of the box, something that’s often very underweighted when dealing with a database…
Overall, Rust is pretty good for performance. Write the most simple, naive stuff, and it will usually run within a factor of two from optimized C/C++ code, without any further performance work on the code. With some investment into optimizations, matching or exceeding C’s speed should be possible in most cases…
In this post I will unfold my understanding of what makes a tech team competent in 4 levels with 6 main criteria and 25 sub criteria.

This is a whirlwind tour of some of the cool new features that appeared in Clojure in the past few years. I find it fascinating how one good idea (reducers) morphed into another (transducers), and ended up mating with yet another, apparently unrelated concept (concurrent pipelines) to produce some really powerful…
I stumble upon eigenvectors and eigenvalues regularly when reading about machine learning topics. They seem to be important. They are not introduced in those...
Sam Lewis is a Melbourne based geek who develops cool bits of code. He likes data, embedded stuff and AFL.
It's difficult to get the Windows Console to display Unicode characters, so here's a C++ WinForms program that will display the arguments in a TextBox.
Nobody wants to deliver late, over-budget software. I don’t know a single software developer who wakes up in the morning and thinks “I’d like to do a rubbish job today. How can I cost my employer more money?” And yet, so many software projects don’t go well. And with every new project, there seems to be more and more…
This started out as a Hacker News comment about a blog post about select being fundamentally broken After that the same author wrote why epoll is broken as well. I don’t know what problem author is trying to solve but let’s pick this one:
One feature of Rust that I'm rather enamoured with is its macro system. Known as "macro by example" (MBE) or sometimes referred to as macro_rules , it provides you with an impressive amount of power whilst not allowing for the sort of evil tricks you can pull in C/C++.
This article is a starting article in a series that is going to briefly skim through a good engineering textbook on linear algebra, making notes that help yo...
I do not write code for a living. Nor do I study computer science in university. And you know why this is great? Because it allows me to code completely stupid and useless things without anybody being on my back to tell me I shouldn’t. And what I am about to talk is precisely one of these codes…

We’ve read so many sad stories about communities that were fatally compromised or destroyed due to security exploits. We took that lesson to heart when we founded the Discourse project; we endeavor to build open source software that is secure and safe for communities by default, even if there
All my life, my heart has yearned for a thing I cannot name. André Breton, Mad Love
Looking back at my year of Rust. Part reflection, part waymark.
In this post I will talk about some tools that can help us solve a painful problem in Python, especially when using PyPy: memory consumption. Why are we concerned with this in the first place? Why …
