I'm now on day 4 of the Compudanzas tutorial and starting to veer off into unexplored territory to write my little experiments. Thanks a lot to @neauoire and the folks in the #uxn IRC channel for all the help and encouragement!

Here is a little screensaver like thingie I made as part of Day 4.

A few more ROMs are working on the Analogue Pocket Uxn core, and input is hooked up now! I have so much more to do, so a lot of things still don’t work, but a little more progress is always exciting to see! 😀

Next, I’ll try to implement the auto-advancing sprite drawing (where a single instruction could draw as many as 16 sprites).

It's uxn38, running the timer ROM from its example programs! I made a custom rootfs with buildroot and an old kernel on an SD card. I wanna make something out of this cute little puter and #uxn seems to be a good fit!

Spent a bit of time today to make the html5 experience of the #uxn emulator somewhat less awful.

There's a clearly indicated zoom toggle button, a way to share the rom via url encode, and they don't vanish offscreen anymore when the window is too high.

A* pathfinding implemented in Bur, compiled to a #uxn ROM.

I've added copies of source files for most #uxn tools, and other software, here:
http://wiki.xxiivv.com/etc/

These will be automatically updated as I work on them in their individual repositories, but mirrored there for reliability. They are also embedded in their wiki pages, for example:

Well, at least the memory protection feature is worth using. kind of

Basically, sending a magic byte to .System/debug triggers special behaviour, marking memory as readonly, escalating privs to write to readonly memory, or printing out a pretty backtrace.

Not backwards compatible unfortunately, so I added a metadata flag to allow for selective compilation depending on whether the code is being run in a generic #uxn emulator or Bur's builtin one.

I'm finally getting back into #uxn/#varvara, and have run into some trouble following the Compudanzas tutorial - I can build any given .tal file once, but after doing so once if I do so again I get

hello.tal line 0x0000: Memory overwrite: LIT.

in the terminal output from launcher.rom and the .tal file is corrupted - anyone have pointers on where to look to start debugging this? I don't have a lot of C skill at this point, so haven't dug much into the uxnasm source yet.

Debugging compudanzas hello.tal (hello.rom) in Beetbug.

Lovely as always!

It would be fun to squash some of these down into .uf1 files. https://wiki.xxiivv.com/site/ufx_format.html #uxn

For my #DecemberAdventure, I've optimized uxnfloppy so that it runs at 60 fps most of the time at 640x480! Here is a video of bunnymark.tal running on the laptop. It can draw around 2000 sprites before it goes below 60 fps!

Reading @neauoire's posts about character input, got me wondering if it is possible to do character recognition with neural networks inside UXN.

After a few hours of work, the answer is: Yeah, kind of (?)

As a proof of concept I implemented a 3 layer neural network trained on MNIST.
Since UXN has limited memory and no floating point operations, I decided to use a binary neural network: Each weight & activation is quantized to a single bit.

Lurking around the cool corners of Fedi, I recently learned about #DecemberAdventure. https://eli.li/december-adventure

I'm gonna skip Advent of Code this year and instead commit to spending at least a few minutes every day next month working on my now-abandoned Morse code game for #uxn.

Oatmeal - December Adventure

The Advent of Code is cool, but a lot, and not everyone’s jam. The December Adventure is low key. The goal is to write a little bit of code every

hey! what do you mean with "I've copied uxnasm into the build folders"? you put it there along with build.sh?

if that's the case, I suggest editing the build.sh file and replacing what I'd guess appears as "uxnasm", with "./uxnasm" so that it runs uxnasm from the current directory.

alternatively, you could put uxnasm in your "PATH" so that you can run it from anywhere—I think that's what the build script is assuming you have. There are many ways of doing that and I don't have a specific recommendation, but hopefully, you can find out how to do it. (if not, let me/us know!)

tagging this with #uxn so that others can jump in.

Despite its lackluster expression, intuitively you feel the angel has a preference, but you don't know what it is.

You're not sure who's side the monochrome divinity is on, but you hope it is the one you're on.
