This is, honestly, not a great program. Once it's launched, it only understands two keyboard inputs,
`ESC` and `q`, both of which simply cause it to exit. Using the mouse, you can pause, restart, and
reset. And that's it, that's all the interaction you get.

As for the name, it's just a perversion of "katabasis", which means, "descent to the Underworld". I
guess a bastardized "bastard" is in there, too. Listen, I'm gonna level with you: I'm not wild about the name, but

## *randical, a commandline program for generating random values*
Some time ago, I was [trying to work out some ways to pick random points in a
sphere](https://blog.joeardent.net/2018/07/right-and-wrong-ways-to-pick-random-points-inside-a-sphere/),
and during that exploration, I found myself wanting to just be able to generate random values
outside of any program program in particular. So, I wrapped a primitive interface around [the random value
generation library](https://docs.rs/rand/0.8.0/rand/index.html) I was using. I wound up using it
selfishly and in a limited fashion for that project, but afterward, decided to expand it a bit and
release it, as my first [real Rust crate](https://crates.io/crates/randical).
I'll reproduce the help text here, since it's fairly comprehensive:
- randical
``` text
$ randical -h
Radical Random Value Generator 1.618033
Generates arbitrary numbers of uniformly distributed random values.
USAGE:
randical [FLAGS] [OPTIONS]
FLAGS:
--buel Prints either 'Here.' or 'Um, he's sick. My best friend's sister's boyfriend's brother's girlfriend
heard from this guy who knows this kid who's going with the girl who saw Ferris pass out at 31
Flavors last night. I guess it's pretty serious.', with equal probability. Not compatible with `-t`
or `--bule`.
--bule Prints either 'true' or 'false', with equal probability. Not compatible with `-t` or `--buel`.
-e, --exit With equal probability, exit with either status 0, like /bin/true, or status 1, like /bin/false.
Technically compatible with all other options, but exit status will have no relation to any
generated output. Sets default number of values to print to 0.
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-n, --num-vals <NUM_VALS> Number of random values to print out. Defaults to 1.
-t, --type <TYPE> Type of random value to print. Defaults to 'bool'.
Possible values are 'b'ool, 'f'loat64, 'U'UIDv4, 'u'nsigned64, 's'igned64, and 'k'suid
with millisecond precision.
```
The [README](https://github.com/nebkor/randical/blob/main/README.md) contains some examples of using
it to do various things, like simulate a fair coin toss, or an *unfair* coin toss, or "a *Sliding
Doors*-style garden of forking paths alternate timeline for Ferris Bueller's presence or absence on
that fateful day."
I have one actual non-shithead usecase for this program: in my [.emacs file, I use it to
generate](https://gitlab.com/nebkor/dotfiles/-/blob/3aaf06fc66cdb541b76dfd44d25c369c4762301f/.emacs#L113-116)
[ksuids](https://segment.com/blog/a-brief-history-of-the-uuid/). But I don't *really* use it.
I include it mostly because, by most measurable metrics, this is my most popular program with end
users that I can specifically identify:
![randical's popularity is baffling][randical_downloads]
Who is downloading my software, and why? I don't know, and I don't care about knowing.
## *freedom-dates, a library noone needed or wanted*
When I started writing this post, "freedom-dates" did not exist as a concrete thing, merely as a
shit-head suggestion by me about the dumbest possible way to represent dates as a string.
