Writing portable ARM64 assembly
Apr 13, 2023
An unfortunate side effect of the rising popularity of Apple’s ARM-based computers is an increase in unportable assembly code which targets the 64-bit ARM ISA. This is because developers are writing these bits of assembly code to speed up their programs when run on Apple’s ARM-based computers, without considering the other 64-bit ARM devices out there, such as SBCs and servers running Linux or BSD.
Help migrate a community from Discord to something else
Mar 8, 2023
During the height of the pandemic, I set up a community using Discord. Since then, it has evolved into being one of the most active (yet tight-knit) technical communities on Discord: members ranging from all around the world and from all sorts of technical and social backgrounds participate in conversations every day on a variety of topics.
pkgconf, CVE-2023-24056 and disinformation
Jan 24, 2023
Readers will have noticed that two maintenance releases of pkgconf were cut over the weekend, 1.9.4 and 1.8.1 respectively, to address CVE-2023-24056, a pkg-config specific variation of the now-classic “billion laughs attack”. While fixing software defects is important, a lot went wrong with how this CVE was reported and the motivations behind its disclosure, and for my own catharsis, I want to talk about this.
Building fair webs of trust by leveraging the OCAP model
Dec 3, 2022
Since the beginning of the Internet, determining the trustworthiness of participants and published information has been a significant point of contention. Many systems have been proposed to solve these underlying concerns, usually pertaining to specific niches and communities, but these pre-existing solutions are nebulous at best. How can we build infrastructure for truly democratic Webs of Trust?
Twitter's demise is ActivityPub's future
Nov 12, 2022
Earlier today, I deleted all of my tweets and left Twitter forever. While I plan on leaving a nightlight thread for a while, I will eventually close my account, assuming Elon doesn’t do it for me. The past week has been an emotional rollercoaster for me as I have watched everything play out.
The internet is broken due to structural injustice
Oct 27, 2022
Over the past few years, I’ve come to realize that the Internet as we know it is utterly broken. Lately, I’ve also been pondering how participants in the modern Internet have enabled and perpetuated harm to society at large. Repeatedly, we have seen the independence of the commons chipped away by powerful men who wish for participants to serve their own whims, while those who raise concerns with these developments are either shunned, banned or doxed.
So you've decided to start a free software consultancy...
Aug 11, 2022
Recently a friend of mine told me that he was planning to start a free software consultancy, and asked for my advice, as I have an extensive background doing free software consulting for a living. While I have already given him some advice on how to proceed, I thought it might be nice to write a blog expanding on my answer, so that others who are interested in pursuing free software consulting may benefit.
Free software grows as a function of social utility
Aug 6, 2022
A frequent complaint I see from users and inexperienced contributors concerning free software projects is that they are allegedly not doing enough to grow the userbase, sometimes even asserting that a fork is necessary to right the course of the project. Are these complaints missing the point, or do they have merit?
Migrating away from WordPress
Aug 4, 2022
Astute followers of this blog might have noticed that the layout has dramatically changed. This is because I migrated away from WordPress last weekend, switching back to Hugo after a few years. This time around, the blog is fully self-hosted, rather than depending on GitHub pages, and the deployment pipeline is reasonably secure.
How efficient can cat(1) be?
Jul 17, 2022
There have been a few initiatives in recent years to implement a new userspace base system for Linux distributions as an alternative to the GNU coreutils and BusyBox. Recently, one of the authors of one of these proposed implementations made the pitch in a few IRC channels that her cat implementation, which was derived from OpenBSD’s implementation, was the most efficient.
