Charlie Kirk spent his life‘s work and all of his energy and time targeting out-groups while arguing for a world in which gun massacres would be easy to enact, plentiful, and inevitable, and he became famous and wealthy doing it, and we’re now not supposed to mention that because it’s not polite.

Jean Pormanove, de la chaîne de streaming sur Kick, est décédé dans son sommeil, lors d’un tournage diffusé en direct.
Il était la cible d’humiliations et de sévices de la part de ses partenaires streamers, avait révélé Mediapart il y a 8 mois.

Welp… I started an #opensource, kind of #osh thing. 🧑💻
I’m designing a RISC-V 6 steps pipeline CPU core, synthesizable on real hardware.
Once the core supports the full RV32I instruction set (bare metal, no CSRs), I’ll add some IO, timers, and turn it into an MCU.
I’m impatient to show it to you !

I promised more FPGA shenanigans.
What about a custom RISC-V cpu that can run C code ?
I’ve designed a primitive single cycle RV32Ish (it’s missing a few instr) CPU and implemented it on the DE10-Lite.
It broke me 😂
What a journey it has been from the @shawnhymel.bsky.social FPGA course to this !

Now that #AppleIntelligence is available in France, I promply installed it.
I'm shocked at how bad it is. Read the reviews, i was sure you were all exaggerating.
It's so bad the "Urgent notifications" thing disturbed me and urged me to respond to... a scam...
Don't get me started on the rest...

Spotted my first #Swasticar « buyers remorse » a few days ago, but I don’t buy it, let me explain
License plates numbers here are issued on a chronological fashion. « GV » kinda means « mid 2024 » Elon was already batshit crazy at this point.
It’s more like a « please don’t key my car »
Fuck that

Rev 2 is now assembled and working !
With only 1 botch wire 😂. I trusted KiCAD a bit too much with the diode footprint.
84% efficiency at 15V to 170V@20mA, not that bad, I think the transformer is not very efficient.
Micromax package was challenging to hand solder 😅
USB-C PD works!

Revision 2 of my Nixie Tube power supply is now in production.
It’s rated for 6 IN-14 tubes @ 2mA, and works with either an USB-C PD 3.0 3A input or a direct 15VDC pin header.
I’ll open source the final revision once I’m sure it does not blow up and everything is fine

I think I settled on something for my « endgame » side project : A Nixie Tube clock based on a custom RISC-V processor implemented on an FPGA, running custom C code.
It combines every aspect of Digital Design and Computer Architecture, plus it’s a fun project. Here’s the power supply! (cont)

Intel's Pentium processor (1993). Looking inside the chip , I found a large, complicated circuit just to multiply by 3 (lower right). Why? The Pentium uses a fast technique to multiply 64-bit number and it turns out that 3 is a special case. Let's take a closer look at multiplication... 1/N

I got laid off today, with the rest of 18F.
18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it.
We made this website to tell our story:

Writing dirty HDL code is already far from easy, but writing clean HDL is way harder !
Reading the amazing book "Digital Design and Computer Architecture" by Sarah and David Harris, I decided to implement in hardware one of the examples, the traffic light controller.

Hey @ifixit.com, i've been waiting for your answer about my nearly unusable FixHub.
It seems that a concentricity defect between the barrel and the jack input (tested with multiple tips) is causing a really flimsy connection.
I hate to do this... but i've waited long enough, please get back to me
