Why the Windows Registry sucks technically (2010)

Raspberry Pi security alarm – the basics
In November last year — I started building a DIY security alarm system, using a Raspberry Pi as the controller. My plan was to make a self-sustained system, using proper alarm hardware — like PIR sensors and sirens. Integration with Home Assistant would be an add-on, not a requirement. I wanted the system to be as…

What they don't teach you about sockets
In order to effectively write applications that communicate via sockets, there were some realizations I needed to make that weren't explicitly told to me by any of the documentation I read.

An Algorithm for Passing Programming Interviews (2020)
Over the past few years, I’ve interviewed with a dozen or so companies and have completed ~50 or so individual algorithm problems. I’m frequently given feedback that I did a great job at the algorithms problem. In this post, I’m going to share how exactly I approach algorithm problems. Thought Process A guiding…

Web automation: Don't use Selenium, use Playwright
For web automation/testing, Selenium has been the de facto "standard" since forever. It's simple to get started with and supports almost every programming language. My problem with it has been: It's good enough, but nothing more. It doesn't work that well with modern, Javascript framework heavy sites (Angular, React

What’s so great about functional programming anyway?
To hear some people talk about functional programming, you’d think they’d joined some kind of cult. They prattle on about how it’s changed the way they think about code. They’ll extol the benefits of purity, at length. And proclaim that they are now able to “reason about their code”—as if all other code is irrational…

Useless Use of "dd" (2015)
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…

Keyboard shortcuts for GNU Readline
Most command line programs that offer line editing -- like bash, Python, GDB, psql, sqlite and more -- do so using GNU readline. Readline's a powerful library that grants history, completion, movement and editing to programs that use it --- and a stable and consistent set of keyboard shortcuts. Shame, then, that even…

Terraform should have remained stateless

C Isn't a Programming Language Anymore
Phantomderp and I have both recently been very aligned on a particular subject: being extremely angry about C ABIs and trying to fix them . Where we’re not aligned is why we’re mad about them.
