Ever wonder why compilers use `xor eax, eax` to zero registers? It's smaller AND faster—CPUs optimise it out entirely!

There has been one other person with so much power that they were able to shoot a layer in the face, hospitalizing said lawyer, causing that lawyer to have a heart attack, and then the lawyer apologizing to the guy that shot him in the face.

Conversion therapy is another term for child abuse.
A majority of the Supreme Court signaled Tuesday it is prepared to rule against Colorado’s ban on “conversion therapy” for minors, with several justices signaling they agree with a licensed counselor in the state who says the law violates her First Amendment rights.

I wrote my first and maybe only Substack post. This is a follow up to my Colwell post because I found a 2007 technical report by two MS employees who interviewed folks from MS, AMD, and Intel about the history of the transition, and I learned a lot!

I love this post by Todd Austin equating running a kitchen to a modern out of order microprocessor, especially with the inclusion of precise interrupts, prefetch, and power gating.

My Lisa story is that in early 2020 we had a buggy driver launch that caused a game to crash repeatedly. I emailed Lisa telling her that the driver was buggy, my horrible experience with Radeon drivers in 2001 made me

My long-in-the-works Big Interview with AMD chair and CEO Lisa Su is out—and more timely than ever. We talk about export controls, AMD’s growing data center business, AI in healthcare, what drives her (aside from Starbucks & boxing), and of course, competing with Nvidia www.wired.com/story/lisa-s...
Lisa Su Runs AMD—and Is Out for Nvidia’s Blood
While everyone else has been talking about Nvidia’s GPUs, Lisa Su has discreetly turned AMD into a chipmaking phenom. And as the US-China tech war rages, she’s at the center of it all.

PCIe 8.0 has been announced, so a reminder that since Gen 3, the link transfer rate is 2^(PCIe gen), and from there you can derive the bandwidth for any link width.
e.g. Gen 8 x16 = 256 GT/s * 16 lanes / 8 bits/B * 2 directions = 1024 GB/s = 1 TB/s
