Because I've done development both for embedded arm microcontrollers and CUDA. ARM feels like a benevolent overlord that wants to help you. Documentation is open, compilers are easily accessible, there's lots of random blogs with best practices on how to do common operations. Nvidia feels like their entire goal is to extract as much money out of you as they can.
I'm not hoping ARM fails. I'm hoping the sale fails, because if the sale succeeds, ARM will fail.
> I've also heard that the congressional paging system locks devices when an emergency is announced
If computers locked automatically when an emergency is announced, it doesn't matter if the staffers evacuated quickly.
Once an IC is designed, the datasheet doesn't substantially change. It isn't a computer program that gets continuous updates every couple of months. They might add some errata for some corner cases or clarification. What happens when the IC is discontinued? I still need the datasheet, so I can understand the circuit when finding a replacement IC.
It's absolutely amazing how good of work they do using ridiculously crude tools. Extremely skilled people. I strongly recommend you don't watch if you're a manager or OSHA inspector, though.
Find a game disk that was a demo (like from a magazine). It must have a main ELF, that would then launch another ELF from the disk. (For example, the main menu would be one ELF, and then each demo game would be another elf). Create an iso, then replace one of the game ELFs with whatever executable you wanted. The resulting iso must have the same layout, with every file at the same location. Burn it to disk. Tear apart the PS2 and remove the top of the disk drive. There's a little white plastic piece with a magnet that clamps down the disk, remove that from the lid of the disk drive. Put the original disk in the drive, clamp down the disk with the magnet, and boot it up to the menu screen of the demo disk. Without hitting the eject button, use your finger to stop the drive, lift out the original disk, set in your burned one, put the magnet on top, and choose to run the game that corresponds to the ELF you replaced. Voila.
Really, learning how to braze and weld steel helped me a lot. Heat control is extremely important. Heat flows, and you learn how to position your iron to get the heat where you need it. You can also tell how hot something is by how the puddle looks.
I still don't understand how it seals better than a Wankel. I understand how it's turned inside out, and it's very clever, but it seems like it would have the same problem with seals.
