Fixing recursive uploads with lftp: The tale of the rogue symbolic link

I've been setting up continuous deployment recently for an application I'm working on, and as part of this process I'm uploading the release with sftp, using a restricted user account that is both chrooted (though I use a subfolder of the home directory to be extra-sure) and doesn't have shell access. Since the application is written in PHP, I use composer to manage the server-side PHP library dep… Read more →


Easy Paper Referencing and Research

For my Msc (Masters in Science) degree that I'm currently working towards, I'm having to do an increasing amount of research and 'official' referencing in my University's referencing style. Unlike when I first started at University, however, my now I've developed a number of strategies to aid me in doing this referencing properly with minimal effort - and actually finding papers in the first place… Read more →


Delivering Linux 101

Achievement get: Deliver workshop! At the beginning of my time here at University I never thought I'd be planning and leading the delivery an entire workshop on the basics of Linux. Assessed coursework presentations have nothing on this! Overall, I think it went rather well, actually. About a dozen people attended in total, and most people seemed to manage to get near the end of the tasks I had pr… Read more →


Easy Ansi Escape Code in C♯ and Javascript

I've been really rather ill over the weekend, so I wasn't able to write a post when I wanted to. I'm starting to recover now though, so I thought I'd write a quick post about a class I've written in C♯ (and later ported to Javascript via an ES6 Module) that makes using VT100 Ansi escape codes easy. Such codes a really useful for changing the text colour & background in a terminal or console, and f… Read more →


Automatically rotating log files on Linux

I'm rather busy at the moment with University, but I thought I'd post about Linux's log rotating system, which I've discovered recently. This post is best read as a follow-up to my earlier post, creating a system service with systemd, in which I talk about how to write a systemd service file - and how to send the output of your program to syslog - which will put it in /var/log for you. Log rotatin… Read more →


ASP.NET: First Impressions

Admittedly, I haven't really got too far into ASP.NET (core). I've only gone through the first few tutorials or so, and based on what I've found so far, I've decided that it warrants a full first impressions blog post. ASP.NET is fascinating, because it takes the design goals centred around developer efficiency and combines them with the likes of PHP to provide a framework with which one can write… Read more →


Troubleshooting my dotnet setup

I've recently been setting up dotnet on my Artix Linux laptop for my course at University. While I'm unsure precisely what dotnet is intended to do (and how it's different to Mono), my current understanding is that it's an implementation of .NET Core intended for developing and running ASP.NET web applications (there might be more on ASP.NET in a later 'first impressions' post soon-ish). While the… Read more →

Generating Atom 1.0 Feeds with PHP (the proper way)

I've generated Atom feeds in PHP before, but recently I went on the hunt to discover if PHP has something like C♯'s XMLWriter class - and it turns out it does! Although poorly documented (probably why I didn't find it in the first place :P), it's actually quite logical and easy to pick up. To this end, I thought I'd blog about how I used to write the Atom 1.0 feed generator for recent changes on P… Read more →
