Interview with Spihon

That’s an easy one, Which ties in with digital… money. About 2018 I was busy looking for a free art program that I could animate with, since I’m struggling with trying to find a job, so I thought I could do try my hand at making videos for YouTube. And speaking of YouTube, that’s where I found it, from this guy’s video on how to animate, and I was sold so I downloaded it and I’m not going back on it. Actually, the anniversary of when I found it is next month, February 18th, so I’ll have been using it for two years. Truthfully a bit intimidating at first, until I got the hang of it and it became my go to art program for everything I do, from simple paintings to comics. Heck, David Revoy even got me inspired to do it… Sure, I could have added him to the “who inspires me” section but come on! He needs a special place as my Krita Rockstar… Anyhoo, I draw more these days than I play video games. Read more

KnightOS was an interesting operating system

Still, it was a really interesting operating system which was working under some challenging constraints, and overcame them to offer a rather nice Unix-like environment, with a filesystem, preemptive multiprocessing and multithreading, assembly and C programming environments, and more. The entire system was written in handwritten z80 assembly, almost 50,000 lines of it, on a compiler toolchain we built from scratch. Read more

8 Awesome Raspberry Pi Clusters

The Raspberry Pi is an awesome device for the money, but they aren’t exactly known for their raw computing power. Despite that, users have found some remarkable uses for the single-board computer over the years, running everything from arcade emulators to entire home automation systems. That said, sometimes you need more power than a single Raspberry Pi can provide. Fortunately, it’s relatively easy to make several Raspberry Pi machines work together. This is known as a cluster, and they can be powerful enough to rival some of the world’s best super computers. Read more

How I teach physics using open source tools

The nice aspect of being a physicist and a researcher is the openness of our community. There is a lot of collaboration and sharing of ideas (especially during coffee breaks). We also tend to share the software we write. Since we are very picky about algorithms, we want to modify other people’s code to fix the obvious errors that we find. It feels frustrating when I have to use proprietary tools since I cannot understand their inner workings. Having grown up professionally in such an environment, open source has been my go-to solution for all the software I use. When I became the regular teacher of the Physics and Biophysics course at the medical school at my university, I decided to use only open source software to prepare my lectures. Here is my experience so far and the solutions I found. Read more
