Thinking about coding style

After upgrading my blog to support view counting, it got me thinking about programming styles. Do you put your braces on a separate line or the same one as your if statements? What about whitespace and new lines? And then there's even casing of variable names to consider, such as snake_case, PascalCase, or camelCase. As if to add to the confusion, there are also paradigms to worry about. Object-or… Read more →


Using TTN Mapper to show LoRa coverage

I’ve been playing with TTN Mapper. It’s great. There’s an app you can get for your phone (Android or IoS). You configure it with the details of your Things Network application and then you can wander round with a portable LoRa device and help to build a map of coverage. You don’t have to actually connect your LoRa device to your phone, you just have to enable the mapper program on your phone to co… Read more →

Server Discussions at c4di

We had a quiet, but useful, hardware meetup today at c4di. Although most of the talk was of servers and software.We’re in the process of migrating our services onto a shiny new Azure platform (if virtual machines can ever be regarded as shiny). As of today we’ve got the bulk of the work done. This means that you can go to our map and see something useful. We made some changes to the configuration… Read more →

Setting up a Mosquitto MQTT server

I recently found myself setting up a mosquitto instance (yep, for this) due to a migration we're in the middle of doing and it got quite interesting, so I thought I'd post about it here. This post is also partly documentation of what I did and why, just in case future people come across it and wonder how it's setup, though I have tried to make it fairly self-documenting. At first, I started by doi… Read more →


Any Solar Power experts out there?

I want to a meeting with some folks who are interested installing some of our air quality sensors. However, we have a major problem with this because at the moment our devices are all mains powered. This is mainly because the particle sensor is quite a power hungry beast. It needs to be fed with around 120 milliamps. This is not a huge amount, but it is enough to make long term battery powered dep… Read more →


Icelandic Parking Tips

As part of the public service remit of this blog, I bring you my handy “How to buy parking tickets in Iceland” and “How to contest a parking fine in Iceland when you have failed to buy your ticket correctly”. If you park up in Iceland you have to buy a ticket. Don’t work on the fact that nobody else has a ticket in their car window, it’s all done with car registration plates. Pay for your parking… Read more →
