Pandas DataFrame Visualization Tools - Practical Business Python
Introduction I have talked quite a bit about how pandas is a great alternative to Excel for many tasks. One of Excel’s benefits is that it offers an intuitive and powerful graphical interface for viewing your data. In contrast, pandas + a Jupyter notebook offers a lot of programmatic power but limited abilities to graphically display and manipulate a DataFrame view. There are several tools in the

Thoughts on Elixir, Phoenix and LiveView after 18 months of commercial use I’ve been leading a team developing an application using Elixir, Phoenix and LiveView for the last 18 months and accumulated some thoughts on the stack. For the most part, it has been a very pleasant experience. Compared to my initial evaluation of Elixir that I’d done prior to diving in in earnest, it exceeded my expectati

Automated tests are important. Without them, programmers waste a huge amount of time manually checking and fixing their code. Unfortunately, many automated tests also waste a huge amount of time. The easy, obvious way to write tests is to make broad tests that are automated versions of manual tests. But they’re flaky and slow. Folks in the know use mocks and spies (I say “mocks” for short in this
This article was discussed on Hacker News and on reddit. This has been a ground-breaking year for my C skills, and paradigm shifts in my technique has provoked me to reconsider my habits and coding style.

Anyone who has maintained software for a while knows that it tends to rot over time. It takes deliberate effort to prevent that from happening. In this post I will talk about a story how one team successfully dealt with it and conclude with some practical tips. The phenomenon known as bit rot or software entropy has several symptoms: Decreasing MTBF (mean time between failure): the software fails

This article was discussed on Hacker News. Over the past year I’ve refined my approach to arena allocation. With practice, it’s effective, simple, and fast; typically as easy to use as garbage collection but without the costs. Depending on need, an allocator can weigh just 7–25 lines of code — perfect when lacking a runtime. With the core details of my own technique settled, now is a good time to

"Rust does not have a stable ABI" - Federico's Blog
I've seen GNOME people (often, people who have been working for a long time on C libraries) express concerns along the following lines: Compiled Rust code doesn't have a stable ABI (application binary interface). So, we can't have shared libraries in the traditional fashion of Linux distributions. Also Rust bundles its entire standard library with every binary it compiles, which makes Rust-built l
