More interesting is what happened next: an institute in Sofia was reportedly tasked with decapping the ICs, lifting the netlists under a microscope, and reproducing them with socialist lithography

Given that (afaik) the Apple II logic would have all been jelly bean logic or otherwise off the shelf parts did they really reverse engineer ICs?

Hyperion charge money for the OS and don't pay the developers at all, if anyone is greedy it's them

Unless you're a pro photographer who really cares about the camera improvements in the last couple of years?

Just got roped into setting up an on prem temporal cluster myself :(

What causes the need for massive database clusters? Now I'm worried this is going to fall apart on us in a very big way

Yeah I've been using Claude to review a bunch of m68k asm that I've been working on and it's been helpful at catching silly mistakes like using a direct address instead of an immediate value, clobbering registers, incorrect branches etc.

Of course if you just blindly ask it to write asm it will occasionally invent new instructions or address modes but it's very good at reviewing and making adjustments

Turns out the competition had done the most stupid thing and built a read buffer

This isn't really stupid though as explained in the pdf

Paradise had stuck a read FIFO between display memory and the video output stage of the VGA, allowing the video output to read ahead, so that when the CPU wanted to access display memory, pixels could come from the FIFO while the CPU was serviced immediately. That did indeed help performance--but not as much as Tom’s write FIFO.

VRAM accesses are contended, so during the visual display period the VGA circuitry has priority. CPU accesses result in wait states - a FIFO between the VRAM and the VGA means less contention and more cycles for CPU accesses

Why improve read performance though? Games accessing VRAM I presume would be 99% write. Perhaps it was to improve performance in GUIs like Windows?

But to validate those transactions, you must send them to the bank over the internet

Not how it works at all, banks don't have some open API on the internet for processing card transactions
