Dynamic DNS and IPv6 breaking scripts

Just noting, if you have self-made scripts to perform Dynamic DNS with a Nameserver/Provider of your choosing, the following sequence of events happens: * Curl or WGET a page such as https://ifconfig.io/ip to get your external WAN IP. * Parse the response (if needed) * Shunt it up to

Using OpenWRT as a Docker Host (in 2023)

TL;DR: Install docker AND dockerd Unfortunately the Wiki documentation appears out of date for installing Docker as a container host in OpenWRT. The majority of the documentation is fine. However, the instructions tell a user to download 'docker-ce' with opkg, which is no longer possible and presumably out-of-date. The

Fix for slow OnePlus 6 after upgrading to Android 11 (Oxygen OS 11.1.2.2)

If you're reading this your phone has started to chugg hard. The fix for me was to go to Settings -> System -> Ram Boost Disable it. Whatever it is, it aggressively attacks the performance of apps and causes the slow down and lagginess you're likely experiencing. One whole day

Fix/Workaround - libseccomp2 and Alpine 3.13 - Installing Raspbian Docker 19.04+ on Raspberry Pi 4 Buster

If you're reading this you're probably dealing with the hell I've just been through trying to get apps like Nextcloud, Redis and all sorts of other things in Docker to run on a Raspberry Pi4, which suddenly seemed to stop working overnight. The reason? These apps all use Alpine Linux

Can't change Time of Day whilst flying in Flight Sim 2020? Here's a Workaround...

It's incredibly irritating and certainly a bug, when you've disabled the multiplayer element but you're still unable to change the time through the quick access bar at the top of the screen. Especially if you're trying to enjoy the scenery. The trick is to enable Developer Settings in 'General Settings'

Electric Scooters

Every now and then, I'm noticing more and more electric scooters. The other day I saw a ten-ish year old riding one on the pavement, and I'm seeing people use them in the bike lanes in town. It's rare, but the awareness of them is leading to a very slow

My Favourites from London TechDay 2018

A couple of Fridays back, I had the pleasure of heading to London's TechDay event at Old Billingsgate. TechDay is an event which I'd previously never heard of, which was surprising to me as it focuses solely around bringing very early-stage start-ups into the public eye and keeping an eye

InfoSec and BSides 2018

This week I got to enjoy going to InfoSecurity 2018 and BSidesLondon 2018. Both of these events are something I look forward to every year - they're probably the best of their kind each year. They're two distinctly different events though. What are they? For the last few years, InfoSec

How to Fix Broken Websites Protected by CloudFlare

Recently I've come across several websites which have (for some non-obvious reason...) decided to stand Cloudflare's protection services in front of their own website. Maybe for DDoS protection, maybe to filter down requests or raise security somehow, doesn't really matter. The website loads in little pieces with huge gaps in

Raspberry Pi 3B+ - Why the Link/Active LAN Lights "Don't Work"

To help diagnose network problems and/or tell users what speed the network attached to the Pi is running at, the Raspberry Pi devs have used the lights to signify whether 10/100Mb or 1000Mb is being used by the interface.
