The last few months have been an interesting journey for me. Not only have I been having loads of fun (and quite a few late nights) with my Raspberry Pi experimentations, but I have also been spending my working days programming in C. It came as a bit of a surprise when I was first …
This is a bit of a milestone for me. I have got to the point where I now have enough of the ELIUS language to enable it to begin to define itself. This may seem an odd thing to want to do, so I’ll try and explain in a bit more detail what I am …

I guess it happens to all of us. In theory, I make use of as many techniques as I can to mitigate against suffering from mistakes while I’m programming. I use Test-Driven Development, I make small changes and use frequent check-ins to my source code repository. Every now and then though, I lose the plot …
I can’t help but feel that progress is slow on ELIUS, my from-the-ground-up programming language. This is a natural and expected side-effect of only being able to work on it in spare time during the evenings and weekends, but it is still frustrating. Today I made some progress on adding the first set of “primitive” …
I’m a big fan of bats. I even went so far as to make a video at Natterer’s Wood in Bury St Edmunds. I have borrowed a “bat detector” (a device for listening to the ultrasonic noises made by bats as they fly and hunt) a few times, and it has always been very interesting, …
Following on from yesterday’s post about developing code which uses the memory-mapped IO on the Raspberry Pi, but on a separate development system which does not have the same hardware, I began to think about the steps needed for testing such code. The first stage is unit-level testing. As much of the code as possible …
I’m trying to make a concerted push on a first working version of CORNELIUS at the moment, and it’s throwing up all sorts of interesting aspects of software development. For the first version I am building the minimum OS and language in C. However, I am trying very hard to minimise the amount of C …
When I set up this blog, I made a commitment to myself that it would not be just a “link blog” where I note down interesting pages, articles and sites I have found in my travels around the web. I have another blog which pretty much covers that function, even though I have been busier …

I mostly seem to post here when I am thinking about ideas which may have something to contribute to some project or other, but less often when I am just plodding along making progress. Today, though, I have spent my time actually working on the code for ELIUS and making some fairly significant internal changes. …
A few years ago I did some work on a project which used RFID (Radio Frequency IDentification) to do all sorts of cool things. There were several problems with this, though. The first was that even high-quality UHF RFID readers and antennas would sometimes struggle to see and recognize the “tags” we had attached to …
