Early Adventures in Functional Programming

I have been reading about React (so I can eventually learn React Native), and the book starts with a bunch of stuff on functional programming and how it is beautiful.

It was quite convincing, so I decided I would give it a try with a code parser I'm writing in javascript (the reasons why are of no consequence :) ).

In hindsight, I should definitely have started simpler, but it was still a fun adventure and I learned a lot.

I played around with compose() functions which return a function which calls a bunch of other functions in order, and functions which add/remove fields from the data and return it.

It was looking fairly descriptive and not too ugly (any ugliness was surely down to my inadequate understanding of functional programming)...

...but then I tried to debug a piece of it.

I nearly vomited at the giant stack of bollocks which appeared in the callstack window.  How the hell is that giant stream of nonsense supposed to be helpful?

So I'm going back to the drawing board. 

If I had designed the whole thing up front as functional, then maybe it would've worked better.  At least that way I could've tested it in smaller increments.  As it is, I've had an enjoyable afternoon playing with my coding toys, and one hg revert and it's all tidied up again! :)

Micro:Bit and SPI display

I want to explore the full potential of the BBC Micro:bits my school has. Making rock-paper-scissors games and the like is all well and good, and the students love it (for the most part), but it always feels a little bit gimmicky.  But when students really get engaged and suggest ideas for them (e.g. games, compass display), it all gets a little bit cramped and feels like it could  kinda  work, but not really . Then I found out that all the tiny strips on the edge are actually GPIO pins, not just the fat 0, 1 and 2 ones.  Since then, I've wanted to explore what I can do with it. Hence, over the last few days I have been trying to get the microbit to control a TFT display. I first went for this 2.4" display with a touchscreen.  The SPI interface is just for the microSD, not for the screen but I didn't think that would be a problem because the micro:bit has so many pins.  After much frustration, I discovered that there are many of the pins you can't reliably use extern

DCS World with TrackIR under Ubuntu

This is a record of my experience of setting this up.  It's meant more as a record for my future self than a tutorial, but maybe somebody will find it useful. 1 - Install DCS First step, install DCS World via the Steam client as normal.  2 - Install LinuxTrack Linuxtrack Download here: https://github.com/uglyDwarf/linuxtrack/wiki/Downloads   Instructions here: https://github.com/uglyDwarf/linuxtrack/wiki/universal-Linuxtrack-package   Using the gui (ltr_gui) requires qt4 libraries, which I could not find in my standard Ubuntu repositories, so I had to use the ppa instructions here: https://ubuntuhandbook.org/index.php/2020/07/install-qt4-ubuntu-20-04 Run ltr_gui from linuxtrack's bin directory to check everything works so far before moving on to get it running under Proton.  3 - Install LinuxTrack into the DCS World prefix NOTE: Attempting to install for Wine games WON'T WORK e.g. here https://github-wiki-see.page/m/uglyDwarf/linuxtrack/wiki/Wine-Games   This is because Ste

Cardboard Mock-up of USB Joystick

Image
For years now (literally years ), I have been playing around with the idea of making a USB joystick.  You may have seen my previous experiment in building a throttle control . I wanted to use a similar idea to the throttle, taking the angular motion of the handle and magnify it when applying it to the potentiometer.  e.g. move the handle through 45 degrees and the potentiometer gets moved through 90 degrees. I also wanted it anchored at the rear, so I can build a mount to attach it to my computer chair. In the video you can see a cardboard mock-up I made today.  I'm amazed it worked at all, but it even provides a solid foundation for designing the proper plywood one. The process of making a cardboard mock-up was really useful.  There were three fatal flaws in my sketch design which I would not have found out until I tried to make it: Pushing the joystick left/right when it was already pulled full back makes it catch on the rear support. The internal supports in the
