PhD Update 2: The experiment, the data, and the supercomputers

Welcome to another PhD update post. Since last time, a bunch of different things have happened - which I'll talk about here. In particular, 2 distinct strands have become evident: The reading papers and theory bit - and the writing code and testing stuff out bit. At the moment, I'm focusing much more heavily on the writing code and experimental side of things, as I've recently gained access to the… Read more →


I've got an apt repository, and you can too

Hey there! In this post, I want to talk about my apt repository. I've had it for a while, but since it's been working well for me I thought I'd announce it to wider world on here. For those not in the know, an apt repository is a repository of software in a particular format that the apt package manager (found on Debian-based distributions such as Ubuntu) use to keep software on a machine up-to-da… Read more →


Switching TOTP providers from Authy to andOTP

Since I first started using 2-factor authentication with TOTP (Time based One Time Passwords), I've been using Authy to store my TOTP secrets. This has worked well for a number of years, but recently I decided that I wanted to change. This was for a number of reasons: I've acquired a large number of TOTP secrets for various websites and services, and I'd like a better way of sorting the list Most… Read more →


Cluster, Part 1: Answers only lead to more questions

At home, I have a Raspberry Pi 3B+ as a home file server. Lately though, I've been noticing that I've been starting to grow out of it (both in terms of compute capacity and storage) - so I've decided to get thinking early about what I can do about it. I thought of 2 different options pretty quickly: Build a 'proper' server Build a cluster instead While both of these options are perfectly viable an… Read more →


Demystificating VPNs

After seeing yet another article that misunderstands and misrepresents VPNs, I just hda to make a post about it. This post actually started life as a reddit comment, but I decided to expand on it and make it a full post here on my blog. VPNs are a technology that simply sends your traffic through an encrypted tunnel that pops out somewhere else. For the curious, they do this by creating what's kno… Read more →


Own Your Code Series List

Hey there! It's time for another series list. This time it's for my Own Your Code series, where I take a look into Gitea and Laminar CI. Following this series, I plan to also post about my apt repository, which is hosting a growing list of software - including the tiled map editor (support them with a donation if you can), gossa (a minimalist file browser interface), and webhook - if you find any… Read more →


Why the TICK stack probably isn't for me

Recently, I've been experimenting with upgrading my monitoring system. The TICK stack consists of a number of different elements: Telegraf InfluxDB Chronograf Kapacitor Together, these 4 programs provide everything you need to monitor your infrastructure, generate graphs, and send alerts via many different channels when things go wrong. This works reasonably well - and to give the developers credi… Read more →


Happy Christmas 2019!

I've been otherwise occupied enjoying my Christmas holiday this year - and I hope you have been too. Have a picture of a bauble: by Starbeamrainbowlabs | 29-12-2019 at 09:00 am | Holidays | Permanent Link | 0 views | 0 comments | Share via: Read more →


Multi-boot + data + multi-partition = octopus flash drive 2.0?

A while ago, I posted about a multi-boot flash drive. That approach has served me well, but I got a new flash drive a while ago - and for some reason I could never get it to be bootable in the same way. After a frustrating experience trying to image a yet another machine and not being able to find a free flash drive, I decided that enough was enough and that I'd do something about it. My requireme… Read more →


PhD Update 1: Directions

Welcome to my first PhD update post. I intend to post these at bimonthly intervals. In the last post, I talked a bit about my PhD project that I'm doing and my initial thoughts. Since then, I've done heaps of investigation into a number of different potential directions I could take the project. For reference, my PhD title is actually as follows: Using the Internet of Things, Big Data, and AI to d… Read more →
