Only UART. No VGA, no framebuffer. Just UART. Picked up my pipelined CPU Kian StealthV again after not touching it for a year. Just playing around a bit to get back into it and find the motivation to push it towards a Linux SoC.

Dude, I haven’t touched my CPU since February. Getting back into it is crazy, but I just brought it back to life—synthesized and simulated. Can’t wait to hack on it again at the end of the month. It’s insanely fast and will be a Linux CPU. I’m super hyped. SystemVerilog forever.

Wrote a brutal C++23 CPU monitor for my KianV RISC-V Linux SoC on FPGA. It uses 8 GPIO LEDs to show live CPU load. Clean modern C++, signal-safe shutdown, no mercy , just pure hardware feedback.

KianV Stealth Linux RISC-V SoC. First bring-up with a 5-stage pipeline CPU and GShare branch prediction. Running at 25 MHz for now during bring-up, but already timing clean at 50 MHz. Ported my old SoC parts like SDRAM controller and UART to the new pipeline core. Caches are still primitive, memory is single-beat and one clock domain only. Tons of potential left. Fun summer ahead.

Bro... it's kind of crazy. You build a Linux SoC from scratch on an FPGA, get Linux running on it, and your original goal was simply to run a C64 emulator on your own Linux system. KianV StealthV.

Heading back to DC to get the country moving again after the #SchumerShutdown. Not gonna lie, it will be a bit chilly.

I had to check myself just now! As tempting as it is to ride the wave on Phillip Schofield thing it was starting to get a bit dark. It is what it is, no need to push it to far… I said my stuff, let the police look at it. For likes & views it ain’t worth it.

“It never crosses my mind that something’s not going to work. I just keep going until it does.” Dana White’s advice for entrepreneurs: (1) Figure out who you are and (2) figure out what you want to do. After you do that just get up every day and get after it. When you run into a problem, figure it out. There’s no plan B.

"Maybe I should have taken a year or two to just maybe to grow up a small bit........maybe get a year in the States" Only the very best go straight from county minor to senior - Donie Smith regrets it now, there was no rush

"We need to stop looking for excuses not to do it and actually just get on and do it" Responding to a question from ＠LucyJMcDaid, Kemi Badenoch says it is a "weak excuse" to not enforce the social media ban just because some children will get around it.

Tbh, coming back to Mega Chandelure after not seeing it for probably over a month… kinda solidifies it as underwhelming to me It grew on me after I first saw it… but again, after not even thinking about it for a while, it really just doesn’t hit.

Sometimes the internet gets so stupid it loops back around and becomes funny again. Sharing this just to break up the constant news cycle for a second. Sometimes you’ve just got to laugh.

Thought we had a big issue. The calf on my left when I first checked it looked down and cold. After moving cows around in the barn to bring it in I came back to find this. Now I just need to get blood pressure back down.

I'm trying Heartopia, it just came out. I'ts a cute cozy online only game a bit like Palia with hobbies, house building, progression and you can see random players around. Game is free and it has gacha cosmetics (EEHHH), but also a lot of stuff to get by just playing the game.

Mic check 1, 2... Not a news episode (sorry). Been away from the mic for a bit and have come back to find that there is a large block ahead of me. To get it out of the way, I need to share my heart with you guys. -Just Human

You have to push back on your clawd I asked to set up a meeting It said it can’t add Google meet links Literally told it “find a way to solve it” It found a solution and built a skill for it

Patients should not have to sue just to get a second opinion! I have no regrets—I’d do it all again.
