A Friend on Facebook, Kicki, just made my mind buzz. Her post started “Is it possible to 3D print a Menger sponge, M >= 3, and if so, would anyone with a 3D printer make me one?“. (My italics, hee hee, right approach). I don’t have a 3D printer, but my response would be, well yeah, probably quite easily. But...

Breadboards are a wonderful aid to electronic prototyping. They are small plastic blocks with lots of electrical sockets that will accommodate components or wires. Typically you have 2 horizontal rows of sockets in the middle which are lined up to take standard chips with 0.1″ leg spacing and vertical rows at either side, typically used for power rails. The name...

I do watch some mad things on YouTube, in the sense of beyond my comprehension, not necessarily beyond rational thought. Below. A gem yesterday. Anton Petrov does really good astro things. This one caught me because I’m a little fascinated by chaos. The solar system (gods forgive me if I get this wrong) is a massive object with lots of...

There’s a feeble double meaning in the title. This is about what I have in mind for some experiments with ultrasound, but also I’m doing a brain dump to get this out of my head so I can actually get on with things. I apologise for any technical inaccuracies here, I’m still learning this stuff. Before you find fault, I...

I have lots of projects on the go at any given time. Most of these have corresponding GitHub repositories. Even though usually I’m the only person working on them, Git is great for version control and GitHub offers very convenient offsite backup and world-facing presence for the material (were I starting from today, GitHub might not be my first choice,...

tl;dr : push social networks back, Post stuff to your own space first, link to it, worst case copy & paste the content across, with a link. Retain some control, easily done. I regularly post on Facebook and Twitter, occasionally on (many) other social networks. I really like being able to communicate with friends and acquaintances, have fun, share ideas....

You’ve probably followed the developments in Deep Learning in a similar way as I have. Exciting. Naively picking up – win at Go, or more recently, protein folding. That is clever. You may not have had so many years of cynicism about the AI effort. God Damn [1]. I read a lot of fiction books about robots, way before you...

/ Backstory below, but here is how I was able to get WiFi working on a Ubuntu 20.10 Groovy Gorilla Server install (this is mostly from memory, apologies for any slipups). I’ve since installed ubuntu-desktop, seepic. Bizarrely, the server install iso is lacking some very small components necessary for WiFi. These can be found in: libnl-3-200_3.4.0-1_amd64.deblibnl-route-3-200_3.4.0-1_amd64.deb libpcsclite1_1.9.0-1_amd64.deb wpasupplicant_2.9-1ubuntu8_amd64.deb (The key...

tl;dr :machine learning has to be realtime. TensorFlow lite devs need a little history. So much for my determination to get back into regular blogging. Reboot, again. So, like I expect most people that work around technology that are past their first flush, and pragmatists everywhere, I’m not a specialist. But that’s not to say delving deep into any subject hasn’t...
