We'll get to the shrinking, but first let's motivate the binary in question. Three years ago I wrote the "Surfacing Hidden Change to Pull Requests" post which covered pushing important stats and diffs into PRs as a comment. This avoids surprises with changes that affect binary size, manifests, and dependency trees.
Let me tell you about the still-not-defunct real-time log processing pipeline we built at my now-defunct last job. It handled logs from a la...
Back in 2011, I happened to get a job writing Backbone.js app. If you never did that, don’t. I was complaining about difficulties with composition left and right to [...]
Examining the extent of AVX related downclocking on Intel’s Ice Lake CPU
A talk on OpenBSD for beginners
Today, I wanted to see if I could out-compile my C compiler. I added a hand-compiled assembly version of echo from our previous coding exercise and added a new make target, make asm , that will assemble it. Let's look at our hand-compiled assembly and compare it to our C compiler and ask whether or not it was worth it.
Welcome Redditors and HackerNews folks! This post is getting attention outside the QEMU community, so I'd like to highlight two things that...
I built a 28-core gigabit cluster, Kraken, consisting of 7 Raspberry Pi 3 Model Bs.
Why buy an expensive desktop computer when your iPhone is a faster SMT solver?
Continuing on from our tiny snake game , let's explore more into how binaries work on Unix. Let's figure out how our programs come to obtain their argc and argv parameters.

In Prague, the C++ committee took a series of polls on whether to break ABI, and decided not to. There was no applause. But I’m not sure we fully understood what we did and the consequences it could have.
This guide describes how to tune your AMD64/x86_64 hardware and Linux system for running real-time or low latency workloads.
I was looking at one of my classic Macs a few weeks ago, and noticed that my Ubuntu 18.04 netatalk server wasn’t showing up in the Chooser anymore. If you’re not familiar with netatalk , it’s an implementation of Apple Filing Protocol (AFP) that runs on Unix-like operating systems such as Linux and NetBSD. It allows…
A few years ago I splurged on an exercise bike. It’s a pretty expensive item imho, both in upfront and ongoing subscription costs. But I was able to justify it by riding it all the time so that per-ride it wasn’t that expensive. I’m happy to say this was a huge boon for my fitness and it was worth every penny.
A common situation in asyncio Python programs is asynchronous initialization. Some resource must be initialized exactly once before it can be used, but the initialization itself is asynchronous — such as an asyncpg database. Let’s talk about a couple of solutions.
Initially, I wasn’t sure whether to write about this migration project, but when I randomly asked if people would be interested, the response was overwhelming. This was a long, kind of boring, very repetitive, and at times incredibly frustrating project, but I learned a lot, and maybe someone else will learn from this…

The software ecosystem has a lot of useful but unsafe code, and the easier it is to sandbox that code, the moreoften that’ll happen. If it were as simple as ...
A file system is responsible for organising and providing an abstraction over the storage devices where the data is physically stored. In this post, we will learn more about the concepts used by file systems, and how they fit together when writing your own.
Learn about Wayland and Ubuntu Touch on PinePhone... And how we build PinePhone Apps with LVGL
A few years ago I wrote [_The World in Which IPv6 was a Good Design_](https://apenwarr.ca/log/20170810). I'm still proud of that article, bu...
macOS 11.0 will identify itself differently according to the SDK used, and an environment variable does the same for scripts.

You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
hi! Yes, it's been a while since I posted here and yes, it's been a while since I was actively working on FreeBSD's wireless stack. Life's...
