Create new things

Quick scriptlets to create new little assets for various scripting and experimentation

Directory walk

Piecing together some basic directory walking techniques in Go (golang)

Python's method gives some level of completeness, Go's simpler setup means reaching for other libraries to do path operations.

Not hard, just needed to figure that out...

dN range roller

Quick script to see, when rolling a dice set complement of d6, d8, d10, d12, d20 , which are the most frequent numbers to appear.

Use this to determine how to subdivide your Foe Pool

Install Linuxbrew

Very basic linuxbrew installer for general use-case

I've done this in a podman container as root with success; should work in a native environment

Not tried yet in regular user/sudo mode.

ftime - basic timer process

ftime [-t TIMERFILE] -- COMMAND [ARGS ...]

Adapted further into a more featureful tool

A little experiment to demonstrate Python's use of threads is indeed concurrency and NOT parallelism

The script is designed such that a bunch of random numbers are processed - this is an attempt at avoiding chances of the execution runtime trying to optimize out some values. The final value is also printed - not because it's interesting, but so that there is no chance the runtime optimizes for the fact that a variable remains unused.

When running the experiment and displaying htop in another screen, it is visible that multi-processing is happening in procs mode (all CPUs blaze a short while), whilst when I use threads mode, the processing offers just some blips here and there as the main python process gets scheduled wherever it can. I also did an implementation in Go which uses goroutines, and observing the behaviour in htop indicates that these are doing some level of leveraging either multiprocessing or OS threads somehow, as go run gorun.go 10 clearly has all processes firing on all cylinder

Zis : a Zig-Inspired Scripting Language (idea)

These are notes for a Zig-inspired strongly-typed GC language, taking some aspects from Python, and retaining some smiilar simplicity as promised by Go.

Zig brings so several great ideas to the table, but a variant of its apporoach for application-space would be very welcome, so it would provide a similar experience to Zig with many of its characteristics:

error unions
optionals
defer
block scopes

	// Small allocation-less experiment.
	// For sure, there are ways to not allocate at all: passing stack memory locations down.
	// This does mean everything needs to be defined higher up where it is ultimately consumed fully
