Come find me on that new non-crumbling app!

So burning down a warehouse where no one is hurt is “violence,” but a system that sees approximately six unhoused people die everyday in LA County alone isn’t. Got it.

How do you kill a Supercomputer? (Accidentally) using radioactive solder is a good way. IBM’s Blue Gene/L frequently crashed when running simulations at LLNL. Turned out that alpha particles from the lead solder in the board carrier were slamming the L1 cache with bit flips. It’s a particularly nasty issue. Unlike DRAM /w ECC, there wasn’t a transparent way to correct it. The fix was brutal. IBM recommended scientists reprogram critical workloads to write-through mode. Basically, every store in L1 would also travel down the cache hierarchy immediately. If L1 got corrupted, the kernel would invalidate the whole cacheline and force a refill from slower pools. It worked…but had a massive performance hit. As much as 20-30%!

I have to say that this is a brilliant idea! Imagine how much electricity could be generated by the vast amount of parking lots in North America alone.

First Black Cat cover I’ve done , there another one coming soon …..

“guess anyone can be an SI Swim model now” ohh okay. so you do it.

Torching the @InternetArchive & the @WayBackMachine is akin to burning the Library of Alexandria and wiping our digital memory - at a moment when media corporations & the government want to hermetically seal us in a bubble of their propaganda. We can't let this happen.

In the 90s, Hitachi came up with a bizarre way to conserve memory bandwidth. Their SuperH architecture, intended to compete with ARM, was a 32-bit architecture that used…16 bit instructions. The benefit was really high code density. If you can fit twice as many instructions into every cache line, the CPU pipeline stalls way, way less. This was *really* important for embedded devices, which were often extremely bandwidth constrained in the era. Sega famously used the processors for the Dreamcast, and ARM actually ended up licensing their patents for Thumb mode! I think perhaps the weirdest thing about SuperH was its concept of “upwards compatibility”. The ISA itself is a microcode-less design, all future instructions were trapped and emulated by older chipsets. It’d be slow…but you could run future code on very old chips! Very neat design, a massive success through the 90s and 2000s, that slowly faded.

@emkenobi It's darkly amusing that nobody misses him outside of the absolute worst people. On the flip side the people who miss ANDOR are the real ones.
