Further thoughts on Forth (and Riscyforth in particular) and Life
It’s now two years since I began my Riscyforth project of writing a Forth for RISC-V single board computers. But it wasn’t until yesterday that I wrote my first serious/useful (if you like this sort of thing) program for it, a version of Conway’s Game of Life. (This program wasn’t as long as the unit…

Game of Life animation
I’ve made some improvements to the program and so here’s an animation of the output.

Write-only? A simple program translated from C to Forth
The old joke is that Forth is a “write-only language”. in other words, you can write this stuff but you cannot understand it (and hence maintain it). Of course, any endorsement of this view is regarded as a heresy amongst many in the Forth community, but I have to admit that sometimes the Forth-bashers have…

Does “coding” have a future?
Today is, for me, the last working day of the year and I was able to finish with a small triumph – successfully solving several programming conundrums that have eaten into my time over a number of weeks. The technology involved – Python – is not one I have had much experience with, and only…

This summer’s to-do list
It’s easier to produce this list than it is fo do them, but producing the list is also a means of holding myself to account: Complete the code to translate a string into an IEEE754 floating point number in Riscyforth: I am now pretty clear in my own head what the algorithmic steps to do…

Adding dynamic linking to Riscyforth
This is one of those blogs one writes to clarify inchoate thoughts, so it’s sorry-not-sorry if it starts to wander around… Last week I got to an important point with Riscyforth, my Forth for RISC-V single board computers: I tagged my first release (v0.1). I did that because I had, finally, managed to cover all…

Getting the POSTPONE word to work in Forth
I have struggled with this issue for several weeks now and I didn’t find the explanations in Starting Forth or the 2012 Forth standard or even the GForth documentation particularly enlightening, so I wanted to write this to – hopefully – add some clarity to anyone else trying to get this right in their own…

More on the Riscyforth versus Gforth shootout
This is a further post about optimising Riscyforth, my Forth language for RISC-V single board computers. Riscyforth is a 64-bit Forth which runs on top of Linux – my test system is the Sipeed Nezha SBC – which runs a 1 GHz single core CPU (so 1 cycle is one nano-second). I’m testing it against…

A book recommendation
Lying in the bath this morning – relaxing into the Christmas holiday (despite the raging epidemic of omicron-variant Covid that is currently rampaging through London in an increasingly frightening manner), I had thoughts about several blog posts to write over the break, and this is the first… It’s a book recommendation: Ian Stewart‘s Concepts of…

Riscyforth: an update
Last Christmas I started work on a Forth for RISC-V single board computers (SBCs): Riscyforth. Riscyforth is written in RISC-V assembly, with the aim of providing a good balance between the ease of use that comes from a programming language that can both be run in an interpreted “immediate” mode and compiled if speed is…
