Who out there would find a Computer Architecture blog or podcast interesting? What if I arranged to do one in collaboration with folks like @AMD, @Arm, @intelnews, @risc_v?

I started a new job at @Google working on hardware/software codesign this week. I would like to thank everyone for the warm welcome! My own Noogler hat is on the way, thanks to @SRobTweets for loaning me hers for this photo 😀

Today the industry will be removing the Out of Order backend from all future CPUs. After all, only 20% of the transistors are required to make the CPU work!

How many other fellow nerds would rather watch an AMD/Arm/Intel/RISC-V architecture day than go see a movie or a sports game? 🤣

This is awesome. People who vote against their own interests. It’s like Republicans in all of the United States

Apple don’t get enough credit for their work on their GPU since the CPU cores are ridiculously awesome. But the GPU is crazy too. Kudos to them for the work on M5 💪

Apple M5 that fits inside 5.1mm fanless iPad, beats the M1 Ultra, Quadro RTX 5000, and RX 9060 XT in Blender rendering performance

Today is my last day at @RedHat (again). I am leaving to pursue an opportunity at the intersection of hardware and software. I am not sharing where today, but I plan to make a dent in the universe. Farewell Red Hatters, you will always be like family :)

Leaving Red Hat
Here we are (again). Today is my last day at Red Hat for a second time. I leave behind several amazing teams spanning the gamut from Arm…

PSA: there is not now, nor has there ever been, an architecture known as “Arm64”. There is an architecture known as Armv8, which has an execution state known as AArch64, in which a PE (Processing Element) executes A64 ISA instructions.

For decades I ignored all Microsoft developer documentation. I only just discovered how amazing their C++ docs are. The lesson as always is to stop living in the same bubble forever. Open Source is great, but you can’t ignore the wider world around you.

It’s actually a great thread but not for the reason the original poster intended. It’s brought out a lot of people with terrible ideas on how to mistreat candidates or jump to horrid conclusions

Today's thought while running: when I was in my early 30s, a colleague warned me it was all down hill from here and I would stop being able to learn new things. At 38, I've learned more in the past 3 years than I did in the first 35. Don't listen to negativity.

Today is my last day at @nuvia_inc. It's been a privilege to get to work with so many amazingly talented people who are well on the way to disrupting the datacenter in the years to come. In a week or so, I will be returning to @RedHat. More on my decision:
A new direction — rejoining Red Hat

Anyone want to suggest he build a magic compiler and bring back Itanium or is it just me who wants to watch that? 🍿
