A concise summary of Python’s versions, and what’s in each.
tl;dr: dd works for reading and writing disks, but it has no "low level I/O" capabilities that make it more suited for this than any other shell utility. Like cat you should use it where it makes sense, e.g. to take advantage of its wide array of options, rather than try to ensure that all disk related commands begin…
Building on last week’s post on tanks and a few of the comments there, this week I wanted to talk about the ancient (and medieval) weapon-systems often analogized to tanks and the degree to w…
Before my first kiss, I scoured The Internet (Google Scholar + tracing blog posts back to their underlying studies - this was some time ago so I don’t still have the sources) for every valuable scrap of information available on the topic while trying to stray away from anything opinion-based. This is the result.
How and why to use the second most powerful question known to software development
I love Ruby! I’ve used it every day for years and I’m not sick of it yet. It’s an easy language to love: it’s expressive, flexible and syntactically beautiful ; it has a unique combination of useful features like mixins , metaclasses and blocks ; it comes with a useful core library and comprehensive standard library …

A book review of my journey through dependent typing.
In-flight messaging I was on a Delta flight the other day, and I was thinking about how they offer free messaging from your smartphone. How do they limit the wifi? Maybe they have some basic filter that says “deny everything except the urls for these 3 messaging apps”, which makes sense conceptually. What if we don’t…
Nuclear power plants produce around 20% of US electricity and the majority in France. Yet the industry is stagnant. Let's look at why.
There’s a feeling in the air. A zeitgeist. SPAs are no longer the cool kids they once were 10 years ago. Hip new frameworks like Astro, Qwik, and Elder.js are…
... in which we look at one or two ways to make life easier when working with Python regular expressions.
I spent most of April and some of May traveling around Ukraine, visiting the cities of Uzhgorod, Lviv, Kyiv, Kharkiv, Dnipro, and Odessa. As with my other travels, I’ll write down thoughts and obse…
It’s an exciting time in the Lotus 1-2-3 enthusiast community – that was a joke, there is no enthusiast community, it’s just me! 😆
The Dangerous Professional finds the seams between the policies, and slips inside them to Get Stuff Done
A friend of mine recently brought up his custom mechanical keyboard while we were hanging out in voice chat, and at first, nobody understood why anyone would buy one. At that time, I had no clue that there are entire communities about building custom keyboards. With every sentence that was said, we got deeper into…
Finally! On May 19, 2022, GitHub released one of its most requested features: Math support on Markdown! Many had been anticipating this for years, including myself, so much in fact that I wrote a browser extension to get there early. (xhub, it can do a few other things so check it out.)
