TL;DR pymarkdownlnt provides an easy way of checking that any Markdown you’re working on is complying to some sensible guidelines. If you’re comfortable with Python virtual environments you won’t really need the rest of this post. Why? I’ve spent a bunch of time recently adding OpenSSF Scorecards to the key Atsign repos. Build better security […]

September 2021
Pupdate There was a local sausage dog meetup, which was a lot of fun for the people and the dogs: GraphQL I had to spend a bit of time learning GraphQL, as it’s used by the latest GitHub APIs, and there’s no other way to access the data behind the Projects (beta) boards. There’s a […]

Managing GitHub Labels
I was on a sprint planning call last week where it felt like we spent way too much time getting the labels in our various repos straightened out. After a little Googling I found various scripts that use the GitHub API to manage labels. But nothing that seemed easy enough. So… I pulled together my […]

The @ Company uses a lot of SSL certificates, and we’ve been using ZeroSSL and its Certbot wrapper zerossl-bot to automate how we manage certs. But we wanted more control over the process, which has driven us towards the ZeroSSL API. Sadly the docs don’t provide usage examples, which has made it quite a journey […]

Learning to Code
TL;DR Code defines our relationship with machines, and we all have a unique relationship with machines because we all learn code differently. This is my journey. Yours won’t be the same, because ‘the past is a foreign land’. All that I can hope is that there are some lessons/inspiration here. Background This post was inspired […]

micro:bit Simon
The BBC micro:bit is a computerised project board that’s being given to every year 7 (11-12yr old) kid in the UK. It’s supposed to encourage experimentation and learning to program in the same way that the BBC Micro (and associated BBC programmes) did back in the 80s. I’ve been pretty excited about it since the announcement, […]

I’ve been very happy with the results from my Raspberry Pi controlled water bath for sous vide cooking, but I knew that the control loop could be improved. Past runs show fairly continued oscillation: I’ve been keeping track of the average power for my control loop, which has been coming out at 22%. So i […]

Temperature control for a sous vide water bath is a popular application for hobbyist microcontroller kits, with lots of well documented projects out there. My favourite is the Sous Vader – if only for the attention to detail in the decal on the box. I’ve been planning my own for a little while, and got […]

In part 1 of this series I looked at ladder board, and in the next part I plan to review the Gertboard. This post is about Quick2Wire‘s boards, where I’ve been fortunate enough to try out some alpha and beta samples. Quick2Wire concept There’s an interface board that connects to the general purpose input output […]

Raspberry Pi GPIO Joystick
After getting MAME going on my Raspberry Pi so that I could play old arcade games. I wanted to hook up a proper joystick. Back in the 80’s I had the excellent and ubiquitous Competition Pro 5000. As mine (foolishly) got sold with my Amiga stuff I got one on eBay, and it came in […]
