I love this a lot! I want to put function pointers in a "matrix architecture
array" and make them point to different functions at different points in the
program. I bet you could even point them at each other, so like if M and Y
then point at N, A, Y or something.
this is really cool I like stuff like this tomorrow I'll take pictures of
something similar I'm working on! I abandoned it tho hehe anyway remind me if
I forget!!

if you'd like I can give you a lua script which will take your fediverse
archive and turn it into a pdf which you can edit or print or whatever. Might
be a fun diversion from posting. You can reply to yourself, add
clarifications, change some things, put things in a new light, add context,
etc... before you know it you'll have something printable. Could even pull out
your best stuff and make zines.
should require just a little configuration to suit your setup. That's part of
how I stay "productive" without posting all the time.

I love writing installation scripts like this!
If you want to install something on Linux but you have difficulty, talk to me
and I'll write you a script like this. I might even make it fancier.
This one installs a programming language that is useful for parallel computing
across multiple clusters of computers which could be useful if you want to
leverage multiple CPUs and GPUs with ease to compute tasks which are far
beyond a normal computer.

the neat thing about BASH is that it's the glue that holds all your other code
together. Write libraries in C and call them with BASH - accomplish broader
tasks that are easier to co-create. That's why I like it - it's not the most
important, but it's quite beneficial I think _^

can't stop thinking about a visual programming editor that can be interacted
with in the same way that people are used to (think chromebooks dragging and
dropping icons in a web UI) but produces a text-file full of code and all the
required compilation scripts for any language the user requires...
seriously, programming is not THAT different between the different languages.
especially the main ones. they're all essentially variables and function calls
at the end of the day, so why not abstract away all the extra details and
build something that n00bz can actually use to build things.
I technically could make this but I don't have the bandwidth and I don't think
it's important really? who can say, the tools tend to co-create the solutions
in my experience.

I know you don't want to hear this, but there is a chance that there will come
a time where your life depends on your ability to debug a computer without the
internet. To set up an SSH server. To install Linux. To program in C. To do
something else that I'm not prepared for... If StackOverflow didn't exist
because network connectivity has been lost, could you remember syntax? Maybe
it's a good idea to set up a local LLM that can answer basic questions about
technology. Maybe it's a good idea to set up on your parents computer, just in
case you have to hide out there for a couple months. Maybe it's a good idea to
download wikipedia, just in case.

they're farther on the circuit-board from their host and their reception at

sometimes I think about how much more productive I'd be if I had a code editor
that let me draw arrows and smiley faces and such alongside the code. Or if I
could position things strangely, like two functions side-by-side with boxes
drawn around them. Or diagrams or flowcharts or graphs or...
something that would output to raw txt format, but would present itself as an
image that could be edited.

yes... I like tree shapes, you have to address them differently. Lots of
pointers, in my experience, which can be kinda fun.
I also like large heaps / soups of data that points to one-another. Structs
thrown in a pile with pointers to each other. It's great! So long as those
pointers can also point back, and you can properly trace how data flows
through the system... That's the hard part, I think.
trees though... You can start by just saving a "next / previous" with one or
both being arrays of pointers to the next or previous entries. Note: plural,
entries. That's the fun part - non-linear trees teehee

the reason you start with a game engine is because then you'll have tools to
make however-many games you want. Tools that you know intimately enough that
you can debug and improve them without breaking your creative flow by learning
something new halfway through a project
the whole point of individualized projects instead of viewing each computer as
a complete and total whole (why do we need servers again?) is that you can
paint a picture of where the design of the program is intended to go, such
that all the considerations are in place and whatever issues or struggles you
might face along the way are adequately addresssed, -- stack overflow --
[because I mistyped addressed] -- -- if you know what "stack overflow" means
you have intimate knowledge of the technology, and can probably guess what it

source code should be like a story
"here's why we did what we did with our architecture"
and as it's being written, it may be altered in many different places at once
- git style.
parts of it could rhyme,
if they wanted to show parts that were really difficult but easy to summarize
because it's mostly just a lot of boring work y'know like writing getters and
setters and doing the testing pre-deploy environments

yeah that's probably better too since it'll be easier so there'll be fewer
bugs, especially since processing audio isn't usually performance critical ^_^
TBH I just want people to make more threading primitives like locks,
semaphores, and iterators. Like... thread pools, or hashmaps that run a
function on each record stored within every time each of the threads passes a
checkpoint, or paginated arrays of data that run a function on themselves and
the records near them (with slightly different input values, of course) idk
what those are called but I can't resist putting them in everything
Anyway I do think multithreading programs that don't need it will teach you to
be a better programmer, so... depends on what you're working on I guess. Are
you preparing to be ready and working, or are you ready and working?

I love programming!! Currently working on learning decentralized and GPU
oriented computing. It's lots of fun! Plus Bash is a great language, it's not
funky or hacky at all. Just a great language. Haha suuuuch a great thing to
play with.
But GPUs are legitimately cool, aside from Bash's purported funkiness /
hackiness. You can do all kinds of cool things at scale that just don't make
sense up close.
