ZFS sometimes benefits from having a logging drive. Usually, you need to assign a whole device or partition to it. Unfortunately, I had already partitioned my SSD and didn't feel like repartitioning it. So, here's how to create a file, mount it as a loopback, and then assign it to your ZFS pool as a logging drive. Create a 1GB file somewhere on your SSD: fallocate -l 1G zil.img Mount the…

I have a headless server - one without a GUI - which I use as a NextCloud client. My laptop, phone, tablet, and server all sync with a cloud-based NextCloud instance. But, sadly, NextCloud don't offer a way for servers to speak to servers. If you try to run apt install nextcloud it will try to install 300MB of GUI dependencies which you just can't use. Luckily, there's a way around all that!…

Back in 2011, I bought an HP Proliant Microserver G6 for £250. Last week I upgraded to... A Proliant G8 for £270. Nice! Hurrah for Moore's Law! Of course, setting it up is a bit of a mare. So here's a tangled mess of notes to hopefully remind me what to do... Firmware Download the latest gen8 firmware / BIOS / iLO. Find a site offering demo licence keys for iLO 4. Boot Order I stuck in an S…

The Mozilla VPN service is great, but it doesn't work using the CLI if you have a "headless" server. After a bit of faffing about, I got it working. I suffered so you don't have to. Get an account Sign up and use code MOZILLA20 for a cheeky 20% discount! Get a token in the browser To start with, you'll need to get an authentication token. This requires you to be on a machine which can run a …

I do not care for the game of Rugby. After many wet and cold days on the school sports field, I had any latent enthusiasm for it beaten out of me. There is nothing you or anyone else can say which will convince me to take an interest in it. You may feel the same way about a specific sport, or the Great British Bake Off, or Linux. That's fine. We're all different. This can be a problem on…

Two years ago to the day, I built Twistory - a service for seeing what you posted on Twitter on this day in previous years. If you've ever used Facebook, you'll know how it is supposed to work. You see posts which show that exactly 5 years ago you were starting a new job, 6 years ago you were at a wedding, etc. The Twitter version never really worked properly because the Twitter API doesn't…

The best thing about WordPress is the plugin infrastructure. A million little gadgets to make your blog better. Sadly, there are all sorts of ways plugin authors can abuse their privileges. Dodgy code and user-hostile features sometimes make plugins more trouble than they're worth. Recently, the normally excellent Blubrry PowerPress plugin pissed me off. It's a useful plugin for publishing…

Skip to instructions I bought a Meta Quest 2 second hand from a child who was bored of it. The Quest was in excellent condition but, after a few days use, it became clear that the physical volume up key was broken. There are lots of tips and trips for fixing this. One of which is factory resetting. I turned off the Quest, held volume down and power, and got into the factory reset screen. In…

I'm a huge fan of the US Braille Institute's Atkinson Hyperlegible font. This blog is typeset in it, and I think it looks gorgeous. It's also specifically designed to be readable to people with visual impairments: Atkinson Hyperlegible differentiates common misinterpreted letters and numbers using various design techniques: There's only one problem, the font was released a few years ago and…

I've just finished reviewing a few dozen CVs and Covering Letters. Almost all of them were awful! Candidates - I beg you - make this easy for me! I have been given a fixed set of scoring criteria and you've given me a 2,000 word essay on your life, loves, and hopes for the future. I've only got a few minutes per candidate to read, digest, rank, and score each application. Here's my 100%…

I was asked to help create some pseudo-NFT style avatars for Cambridge Digital Humanities' Faust Shop project. Something with vaguely the same æsthetic as those daft "Crypto Punks". You can see it in action partway through this TikTok video. @cambridgeuniversity Visit the #Faust Shop and see what happens when you make a deal with your digital double. #Devil #EduTok #Cambridge #Performance …
