Inadvertent Storytelling

LoRa Build a Node Workshop at c4di

We've just had a bunch of folks around to build some LoRa nodes. Robin had put together some kits and we came up with a set of instructions. By the end of the day we expected our attendees to have their LoRa nodes sampling temperature, air pressure and humidity and maybe even be viewing the values on The Things Network website.

Search Engine Optimisation: The curious question of efficiency

For one reason or another I found myself a few days ago inspecting the code behind Pepperminty Wiki's full-text search engine. What I found was interesting enough that I thought I'd blog about it.

Waiting for the Ice Cream Machine to Warm Up

We went down to the waterfront today. Wonderful weather, cool breeze from the water. A scene that could be made completely perfect by the addition of an ice cream.We went into the local ice cream parlour. They were just getting going, what with us being there quite early. Anyhoo, the machine wasn't ready for use, and I had this lovely idea that we were waiting for the ice cream machine to warm up. Read more →
