Hello World!
I do low-level programming and FPGA stuff :3
I like modern C++, Vulkan, WebAssembly, VHDL, SBCs, game modding, and Ganqing Impact.[...]

Btw, here's my current setup for the @icepi-zero-bot:
The SBC operating the bot, running the synthesis and recording the video is Layla, my Milk-V Mars (bonus point for everyone who can guess the old name based on the picture). #FPGA.-Icepi-Zero #fedibot #bot #SBC #RISC-V

RAM prices are too high? Pffff, who needs RAM anyway?
Just use flip-flops! #FPGA #shitpost #RAM #I-don't-know-why-the-synthesis/PnR-tools-don't-use-the-RAM

I absolutely love @kenney.nl's input prompts!
They look so good and cute and are literally carrying this project of mine.

Now that kokomi (one of my servers) is finally up again (albeit with different hardware, because more than just its SD card died), my CI builds are finally running again!
Feels good; I've become very reliant on them 😅 #god-I-love-CI #poor-new-SD-card-getting-hit-with-lots-of-load-immediately

And this is Layla (who used to be called Qiqi)! :D
She is a Milk-V Mars and has this beautiful white PCB.
While her SoC (JH7110) is RISC-V and not very powerful (no vector extensions, for example), she does have a ton of RAM (8 GB).

I should have probably mentioned that this is a test for Wafbuntu (the Wafrn client I am developing) and not for federation or anything like that.

Here we (finally) go:

Lastly, this is Kokomi. She also takes partial responsibility for the backups (but a little bit less, since Nahida is also responsible for uploading them to an off-site location).
However, she is very hard-working, because she runs most of the CI builds for my projects... see complete post

This is Nahida. She is responsible for observing (aka monitoring) and remembering everything (aka hosting all my backups together with Kokomi). They run a Garaged cluster together (because MinIO is baka) on two big HDDs.

This is Ganyu. Second only to Keqing and still very fast and powerful~
No NVMe SSD (yet) sadly, but she boots from an external USB 3.0 SSD, so she is still decently fast. But she overworks herself often and tends to struggle sometimes when it comes to memory.

This is Keqing. She is the most powerful and fastest of the bunch, thanks to booting from an NVMe SSD. She forms a Kubernetes cluster together with Ganyu and Zhongli.
