Debugging a Linux network stack crash via a single register value
It’s not every day that you get to debug what may well be a packet of death. It was certainly the first time for me. What do I mean by “a packet of death”? A software bug where the network stack crashes in reaction to a single received network packet, taking down the whole operating system with it.

Python’s Weak Performance Matters
Here is an argument I used to make, but now disagree with: Just to add another perspective, I find many “performance” problems in the real world can often be attributed to factors other…

Go Creeping In
I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between…

Seconds Since the Epoch
This is not at all news, but it comes up often enough that I think there should be a concise explanation of the problem. People, myself included, like to say that POSIX time, also known as Unix time, is the number of seconds since the Unix epoch , which was 1970-01-01 at 00:00:00.

Maybe we could tone down the JavaScript (2016)
I’m having a really weird browser issue, where scripts on some pages just won’t run until about 20 seconds have passed. Whatever you’re about to suggest, yes, I’ve thought of it, and no, it’s not the problem. I mention this not in the hope that someone will help me debug it, but because it’s made me acutely aware of a…

Why is my Rust build so slow?
I’ve recently come back to an older project of mine (that powers this website), and as I did some maintenance work: upgrade to newer crates, upgrade to a newer rustc, I noticed that my build was ta...

Aerc: A well-crafted TUI for email
Aerc is a TUI email client. It had its first release ~4 years ago. This makes it a “baby” compared to most of its “competitors” (Pine was released in 1992, Mutt in 1995). I heard about this program shortly after its first release but ignored it at the time, because I was still reasonably happy with Thunderbird and it…
