Since it's been almost a year since I last posted here... Now I pivoted to making my very own FPGA console/computer!
I'm aiming for late 1990s performance: a RISC-V CPU + a simple 3D accelerator, both running at ~100 MHz and sharing a few dozen MB of RAM.

Not exactly a stance but I firmly believe many, _many_ disagreements can be attributed to people choosing a different answer to the following question:
Would you rather punish the innocent or turn a blind eye on the guilty?

Do you have any extremely niche, but serious, ethical stances?

A Spooky Unix story for Halloween.
A new programmer accidentally ran “rm -rf *” as root, on one of the main computers at the University of Manchester.
He stopped halfway, but /bin, /etc, /dev, and /lib were gone.
What followed was one of the most insane live recoveries in computer history:

What happens when one of the main providers that enables #opensource #silicon to thrive...shuts down? Companies like @mith.ro's new wafer.space jump in and offer an even more compelling option. $7K for 1000 chips on the GlobalFoundries GF180MCU process. Learn more:

Was just thinking about how a lot of kids are growing up now with live service games as their "childhood games", and I wonder how many of those will simply not be playable in any form anymore once they reach adulthood

Just pushed version 0.2:
- If the image has more than 256 colors it just uses the first color.
- PEP now supports RGBA/BGRA/ABGR/ARGB, and dynamically reformats depending on your input.
- You can now choose to make the first color transparent when using pep_decompress().

I am proud to announce...
PEP: Prediction-Encoded Pixels
This format is able to compress images (up to 256 colors) smaller than GIF, PNG, QOI, BMP, in almost all cases.
A lot of passion and research (and fixation) has gone into this:

And it could very well be the best piece of SW I've seen in years. It provides solutions to many problems I had, it has such a bold hacker personality, it is so lean... it is perfect, thanks @tripflag.bsky.social

i would say that having to explain to zoomers how game server browsers used to work and how most multiplayer games would let you self host a server pretty easily if you had the resources would make me feel old if the zoomers in question weren't ironically older than me

are you a platform/embedded developer?
do you need to interact with hardware in a semi-custom manner?
would you like to suffer a lot less doing it?
if so, #GlasgowInterfaceExplorer might be for you. the code below is all you need to build a custom testbench:

it is impossible to generate code comments from source code because good comments are definitionally based on things not in the source code (intent, counterfactuals, experiments, etc.)

implemented a script for #GlasgowInterfaceExplorer that lets you discover the connectivity of any IC with JTAG boundary scan, provided you can give the IC an arbitrary stimulus (here done by using a glasgow output connected to a needle point probe)

🚀 Zed v0.187 is out!
A minimap has been added to Zed, closing out one of our more popular issues with nearly 350 👍s!
To enable the minimap, use `"minimap": {"show": "always"}` in your settings.
Thank you, Evan Simkowitz!

Got Phase Modulation synthesis working on my FPGA! I could play a very trippy audio, but instead I'm using the following FFT to mark this milestone.
I have the pieces to also do PSG, playing PCM samples and mixing signals together, probably the 3 pillars of whatever audio HW I put into my project.
