The New Microsoft

Microsoft now ♥ Open Source and Linux. What’s going on? I gave a short lightning talk on this topic at a local tech gathering. Here are the slides. There’s lots of interesting stuff coming out of MS currently. I’ve been doing plenty of research into this as I’m writing a book on making high performance … 

 

Pi Glowbe – Raspberry Pi Wake Light

Turn a globe into a glowing orb and use it to help you wake up in the dark winter months I’ve written another article for the Mag Pi. You can read it below or get the PDF version. Turn to page 62 (page 64 of the PDF). During the winter, or even at any time … 

 

Cleanweb Jobs

You may know that I help organize a community group called Cleanweb London. We’re trying to help fix environmental problems using web technology. We have regular meetups, so come say hi! We’ve launched a free jobs site imaginatively called Cleanweb Jobs. The aim is to try and get tech talent working on some virtuous software … 

 

5 Years of Pragmatic Tube Statuses

It’s been 5 years since I started this blog. So I thought I’d take a look back at my first post and see how times have changed. The inaugural article was about a mobile optimised London Underground (tube) status page I created. It’s still available at unop.uk/tube although it has changed a bit. The latest …

Fuller’s Brewery Industrial Robot

I recently went on a tour of the Fuller’s Griffin Brewery in Chiswick and came across this awesome industrial robot. It unloads and loads kegs between pallets and the filling line. The robot arm sits between the incoming and outgoing pallets. It services both simultaneously without needing to store the spacers. The empty kegs are … 

 

9 Views and Sea Organ Croatia Solar System Models

I visited Croatia this summer and (in what has become a bit of a tradition) checked out a couple of solar system models. We also went to Montenegro which doesn’t seem to have a model. Kotor, Montenegro does have a strange museum dedicated to cats which is worth checking out. It’s good to know that people …

I’ve tried out Windows 10 on both an old MacBook Pro and on a Raspberry Pi version 2. This post is a more in depth look at interfacing the two together. Standard IoT Core Warning: Windows 10 IoT Core is nothing like normal Windows. There is no desktop and it doesn’t run standard apps. If … 

 

Crossness Pumping Station

You might think it mad to get up early on a damp Sunday morning to visit a sewage treatment works. You’d be right but then you’d miss out on seeing the restored and working Victorian steam engines at Crossness pumping station. As the rest of the site is still a working sewage plant the smell … 

 

Raspberry Pi Sense HAT

I recently acquired a Sense HAT for the Raspberry Pi. This is the same hardware that will be sent in to space as part of the Astro Pi mission. Here it is. It’s a shame that it’s made in China (PRC) and couldn’t be manufactured in Wales like the Pi is. I guess the cost … 

 

Contactless Payment Card Fraud Issue You Might Not Know About

Today the upper limit for contactless transactions rises from £20 to £30. While some worry about high tech fraudsters lifting card details there is a much simpler risk to be aware of. If you hand your card to bar staff and they use contactless payment then you might want a receipt. Especially if they don’t …
