High quality graphics for Latex documents: The Matlab route
You use L a T e X instead of a WYSIWYG word processing program because they can’t cope with the high quality required for publication.

URG
If you asked software engineers some of their “least hated” things, you’ll likely hear both UTF-8 and TCP. TCP, despite being 35 years old, is rock-solid, stable infrastructure that we take for granted today; it’s hard to sometimes realize that TCP was man-made, given how well it’s served us. But within every single…

Go and Simplicity Debt
Fifteen years ago Python’s GIL wasn’t a big issue. Concurrency was something dismissed as probably unnecessary. What people really was needed was a faster interpreter, after all, who had more than one CPU? But, slowly, as the requirement for concurrency increased, the problems with the GIL increased.

16-bit math look-up tables – the unexpected power of scaled-integer math
Floating-point math puts a big overhead on a computer that doesn't have a floating-point coprocessor; but we really do need floating-point for all but the simplest operations— or do we?? Can we really do things like trig, log, and square-root functions without floating point?

Databases and Distributed Deadlocks: A FAQ
A developer FAQ created by the Citus engineering team when they first began working on distributed deadlock detection in the Citus database. Explores when PostgreSQL acquires locks, when deadlocks occur, and how Citus detects and prevents distributed deadlocks in Postgres.

Getting Started with Event Sourcing in Postgres
In a previous post we explored how our application tracks sent emails. We set things up to update or insert a record for each email with the current state (delivered, dropped, etc). In this post we'll look at an alternative data model where we'll store each event as its own record and then roll up t

Manipulate Functions with the J Language
The Pragmatic Programmer recommends that we learn at least one new language every year. To be effective, the languages we learn should differ sufficiently from those we already master and ideally introduce us to a new paradigm too. Learning a different programming language affects the way we view code. A new paradigm…
