"A simple LM3915 based VU meter" by Mohit Bhoite.
This guy's site is full of beautiful free form electronics.
After twenty years of writing #sysadmin nonfiction, I've finally written the perfect sentence:
'“Constantly feeling vaguely unwell” is a common side effect of a career in systems administration.'
Omg, the wonderful Gregory Koberger implemented StackSort, and it is beautiful. http://gkoberger.github.io/stacksort/
Xelix news: Managed to fix the PCI issues I've been having (by making PCI interrupts non-reentrant for now), wrote a driver for Ne2000 NICs and hooked that up to PicoTCP.
Suddenly: Internet! Next up, figuring out how to expose all this properly as BSD sockets in userland.
Probably related to another issue where any PCI interrupt will cause mysterious triple faults. Which is very frustrating since I recently ported the PicoTCP stack, but now have no way of getting packets into it… #osdev
Tried booting Xelix in VirtualBox for the first time in ages. Looks like it's not very happy with the new interrupt handling. I think it fires a nested interrupt right after initialization where QEMU doesn't, and that triggers one of the several reentrancy issues still scattered throughout the code. #osdev
