New blog engine and revamped visuals Monday, 27 Jul 2020
It's been nearly 1,000 days since I published my "relaunching soon" post and I've got my Java rewrite to a point where it's actually usable again. So here's some details on the changes and some reflections on the overall progress of this blog.
My Standard Pi Server Setup Sunday, 17 Nov 2019
I mostly use my Raspberry Pi's as mini servers without a desktop environment, and I almost never hook them up to a display or a keyboard & mouse. So these are the steps I take to flash the SD cards in order to have them already configured to connect via SSH on a known IP address from their very first boot.
Disable swap on Raspbian Buster Wednesday, 13 Nov 2019
While I was recently playing around with Kubernetes on a few Raspberry Pi's, I noticed that after disabling swap it would be re-enabled on the next boot. This was the solution I found to get it permanently disabled.
Setting up logging & metrics in your app Friday, 4 Oct 2019
Singletons, static references and global variables are generally considered evil by most top-rated answers to related questions on stack overflow! However, today I'm going to offer some thoughts on using static logging and metrics recording classes in your applications and why it's not all that bad.
Front-end optimisations Thursday, 7 Mar 2019
In an earlier post, I looked into replacing the Silex PHP framework I originally used to setup this blog (It was my "go-to" framework of choice at the time). Once again, I have to hold my hands up and admit that I have been guilty of just using my "go-to framework" and building upon it without really evaluating if it was the right time and place to use a framework - this time, on the front end.
Radeon VII and Ubuntu 18.10 / 19.04 Friday, 15 Feb 2019
I jumped on the Radeon VII as soon as it was released. Like any new hardware with Linux, there can be some tweaks needed to get it running properly. These are the steps taken to get a new Radeon VII working under Ubuntu 19.04 ( and will probably work for 18.10).
Removing Silex Thursday, 17 Jan 2019
I developed this iteration of my blog platform as an exercise in Event Sourcing and CQRS. As such, I did not want to spend too long learning the ins and outs of a new framework, so I fell-back to one of my old favourites to fill the gap of HTTP request routing and configuring controllers - Silex.
Cross-server lock with MySQL and PHP Sunday, 13 Jan 2019
This is a quick solution for a problem I've come across a few times recently when it comes to running "single tasks" such as scheduled cron scripts in High Availability or Scale Out deployment scenarios where you want to make sure you don't accidentally run the action multiple times.
Is it time to ditch Frameworks? Monday, 29 Oct 2018
Exploring life beyond PHP Sunday, 17 Jun 2018
After 20 years, I'm defecting to the other side! PHP is Slow and Java is Fast!! Here are some of my thoughts and ideas as I go about ditching PHP in favour of Java and exploring how the world of modern Java web apps shape up as I dive into the vert.x framework. I'm not intentionally going to be bashing PHP (although I suspect it might come across that way), but I'm going to try and explore what it is that keeps us tied to PHP even though there are (probably) better solutions out there.
Wildcard SSL certs from Let's Encrypt using acme.sh and Route53 Sunday, 3 Jun 2018
The movement of the web to HTTPS "by default" is continuing at a great rate (which is a good thing), thanks in no small part to the excellent work of Let's Encrypt and major browsers - especially Google Chrome. For this article, I want to run through my solutions for overcoming two challenges I have recently faced with acquiring Let's Encrypt certificates for use in local dev environments and securing web interfaces on the increasing number of devices I have on my local network. In both these scenarios, there is no direct connection to these systems from the internet, so I'm going to be using acme.sh and Route53's for DNS in order to use the ACME DNS challenge verification method in order to obtain the certificates.
Network Speed Testing Wednesday, 21 Feb 2018
As part of another project I am working on, I wanted to make sure I could reliably test the speed, latency and packet loss of a network setup. Not necessarily an internet connection - but the connection between any two devices on the network. So I thought it would be a good time to write up a post about the tools I am planning on using to gather the test data.
Relaunching Soon Thursday, 23 Nov 2017
I am working on relaunching this blog soon. Probably for about the 5th time! Having somehow managed to keep backups of my old blog safe since 2005, I was having a read through the old posts only to find that, to be perfectly honest with myself, 95% of what I was writing about was total rubbish and not worth keeping backups of - never mind restoring into this incarnation of the pheonix! In order to hopefully motivate myself to keep the blog going properly this time, I am setting myself some ground rules...

My ramblings here are mostly about software development with PHP and Java, Linux and server admin related things. Occasionally you might find some things relating to games and woodwork.
