Doing is normally distributed, learning is log-normal
There are few things I think about more than the essays on gwern.net, and there are few with as satisfying a theoretical payout to contemplate in my orb as his essay on “leaky pipelines”, aka log-normal distributions. The skulk: Say you’re working on a Laravel web app. You’re about 90% sure you know how to start the…
Runtime code generation and execution in Go
Disclaimer: I won’t expand on why/when you want to do this kind of hack, and you should not do this unless you know exactly what you are doing. Everything I talk about here is completely unsafe and might not be accurate for the future Go versions. This is not a recommendation, but more of a fun story.

Should I use JWTs for authentication tokens?
Let’s talk about what we’re talking about. JWT stands for JSON Web Tokens, a reasonably well defined standard for authenticated tokens. Specifically they have a header with format information, a payload, and a signature or message authentication code. The core idea is that whoever has the corresponding verification…
Instead of “auth”, we should say “permissions” and “login”
Most computer systems we interact with have an auth system of some kind. The problem is, that sentence is at best unclear and at worst nonsense. "Auth" can mean at least two things: authentication or authorization [1] . Which do we mean for an "auth system"? It's never perfectly clear and, unfortunately, we often mean…
Reclaiming IPv4 Class E's 240.0.0.0/4
Ever since the supply of fresh IPv4 address blocks was depleted there has been a number of interesting market changes, mostly around the costs to either acquire or lease IPv4 address blocks. Since the demand for IPv4 addressing has not changed that much, prices have gone up, and more providers like AWS, Hetzner, OVH…

Evolution of the ELF object file format
Updated in 2025-09. The ELF object file format is adopted by many UNIX-like operating systems. While I've previously delved into the control structures of ELF and its predecessors, tracing the historical evolution of ELF and its relationship with the System V ABI can be interesting in itself. The format consists of…
The one-year anniversary of my total glossectomy
One year ago today, I went into surgery expecting that I’d lose half my tongue to a squamous cell carcinoma recurrence. The evening before, Bess and I got legally married;[1] it was a short, but ch…
macOS Sonoma silently enabled iCloud Keychain despite my precautions
This is a follow-up to my blog post Updating from macOS Ventura to Sonoma silently enables iCloud Keychain . In the addendum to that blog post, I discussed a workaround, which was to delete my WiFi password right before rebooting into the updater. In a trial run on my M1 Mac mini, the workaround was successful.
Old dogs, new CSS tricks
A lot of new CSS features have shipped in the last years, but actual usage is still low. One of the biggest barriers: we need to re-wire our own brains.

Mediocre Engineer's Guide to HTTPS
As a mediocre engineer, I took Internet and HTTPS communication for granted and never dove any deeper. Today we’re improving as engineers and learning a rough overview of how internet communication works, specifically focusing on HTTP and TLS.
Feynman's Garden
The best description of my problem solving process is the Feynman algorithm, which is sometimes presented as a joke where the hidden subtext is “be smart”, but I disagree. The “algorithm” is a surprisingly lucid description of how thinking works in the context of hard problems where the answer can’t simply be looked…

GRC SpinRite
I feel like I used to spend an inordinate amount of time dealing with suspect hard drives. I mean, like, back in high school. These days I almost never do, or on the occasion that I have storage trouble, it's a drive that has completely stopped responding at all and there's little to do besides replacing it. One time…
Chickens in Trees
I was lucky enough to vacation in Kauai last year, one of the oldest Hawaiian islands. If you ever visit, the first thing that you’ll notice — the very first thing — is the chickens.
