xd(1) is a tool that dumps binary input in a more human-readable format. There are countless tools that fit this description, including od(1), hexdump(1), xxd(1), and a bunch of Rust crates in the same vein, but this one has a new trick up its sleeve.
I use Jekyll, a static site generator that’s most notable for powering GitHub Pages. Two years ago, I noticed that the permalinks for several of my blog posts were broken by a Jekyll bug after I upgraded to Ruby 2.4. I’ve since written a Git-based system to stop this kind of breakage from ever reappearing, which should be useful to anyone who uses a static site generator and wants to avoid corruption or inadvertent changes.
I was looking for a job late last year when I saw a tweet about a place called Igalia. The more I learned about them, the more interested I became, and before long I applied to join their Web Platform team. I didn’t have enough experience for a permanent position, but they did offer me a place in their Coding Experience program, which as far as I can tell is basically an internship, and I thoroughly enjoyed it. Here’s an overview of what I did and what I learned.
It’s been two years since I lost my car to a kangaroo. My partner and I went on a road trip from Sydney to Canberra on a whim, but we didn’t reach our destination. We were fine, but the kangaroo sadly wasn’t. Let our story be a lesson to you: don’t drive out of town at night without a roo bar.
Bad Apple!! is a Touhou song whose music video has been described as “the doom of music videos”, because it’s been played on everything from string lights to oscilloscopes. This post is about that video, writing an improved “video player” for Task Manager’s CPU graphs, and using virtual machines to push my feeble hardware to the limit.
In August 2019, the Bitbucket team announced that they would “sunset” Mercurial on 1 June 2020 (now 1 July 2020) by removing all Mercurial repositories and associated content. I urge them to reconsider that approach with this open letter.
The last four years have fucked with me in ways out of which I’ve only really started clawing myself over the last year or so. I went from feeling like I could do anything and improve the lives of the people around me, to feeling like an unreliable piece of shit whose only skills were botching my responsibilities and disappointing the people I knew. I gave up on learning to play the hand I was dealt, neglected the people I love, and grew to cope with all of my problems the only way I knew: by ignoring them. But the scales are finally starting to tip in my favour, and it’s time for me to end my exile.
The licence that one releases their software under is often a topic that’s given less thought then it perhaps deserves. I’ve been releasing my code under the MIT (Expat) licence for as long as I can remember, but I thought it might be prudent to take a closer look at what’s out there in the wild world of software licensing.
It’s no secret that most consumer routers ship with software that’s flaky at best, and prohibitively insecure at worst. While I’ve had good experiences with OpenWrt and pfSense, I wanted to build a router from the ground up, both to understand the stack and to have something to tinker with. I found many solid tutorials out there, but few of them covered the intricacies of both PPP and IPv6. Here’s what I’ve learned.
Human gender and sexuality are immensely complex concepts due to our complexity as a species. Despite this, it’s quite simple to handle gender identity in an everyday setting. You can initially guess someone’s gender, because you’ll probably be correct most of the time. Otherwise, accept any corrections or simply ask them how they wish to be referred, and respect their identity. If you deliberately misgender a person because they don’t pass your personal threshold of physical characteristics to be worthy of their gender, you’re not just being rude, but you’re also espousing an excessively simplified and internally inconsistent conceptual understanding of gender.
Almost every university has a handbook which should serve as an authoritative source regarding which units a student needs to complete to be able to graduate. If you are a computing student at Curtin University, this is not the case.
Tired of the sluggishness of Windows on my laptop and interested in experimenting with a Unix-like that I haven't tried before, I gave OpenBSD a second shot after a brief stint on my netbook a couple of years back. Coming from exclusively using Gentoo, this seemed like a natural choice due to its minimalism and the shared roots between ports and portage. Reading Matthew D. Fuller's comparison of BSD and Linux inspired me to venture beyond the familiar walls of the Linux world.
The ComSSA IRC has an official utility bot, KhlavKalash, which currently does
some trivia like URL title fetching and server uptime. It uses Twisted for IRC
and has a good plugin system with Yapsy. Feeling a bit bored, I decided to try
my hand at implementing what I call a "sedbot", which interprets messages that
sed replacement expressions, executing the replacement on the
last normal message.
Until May last year, I was a customer of name.com for a domain name and DNS services. Having just grown out of a comfortable walled garden of all-in-one shared hosting and DNS perhaps about a year prior, I knew little other than that I should avoid GoDaddy. I since discovered that name.com was pulling a scummy trick that an increasing number of name service providers engaged in.
This was originally going to be a quick guide to Windows Deployment Services with Windows Server 2012. Using it to install Windows Vista and newer is trivial though, with the introduction of the WIM format. However, upon finding a laptop that needed Windows XP and could only externally boot via PXE, things changed a little.
In an effort to avoid using any email UI other than the familiar embrace of Gmail via Google Apps, one of the first things I did when I became a Curtin student was to forward my email. I couldn't quite filter all of the incoming emails properly though, until last night I had a sudden realisation.
I've seen several quick, web-based configuration testing tools for clients and servers of various protocols, so it could potentially be helpful to someone if I compiled a list of them here. These tools test not only that your servers are working, but that they are configured in accordance with best practices, and I use them all heavily. Let's start with TLS, DNS and SMTP, though I'll try to find more in future and append them here.
Alternatively, How I Learned to Stop Worrying and Love UTC. It was a little more subtle than I had expected to ensure that Jekyll uses an arbitrary timezone for dates in posts and their generated URLs, but is that even a Good Thing™ to do?
The fx-82MS is a cheap two-line scientific calculator that I fondly remember using for countless hours since the beginning of high school. It's so reliable that after using the same one for over six years, the worst that's happened is a bit of corrosion on the rear screws. Here are a couple of useful tricks I've found after digging through forums and videos.
