One of my biggest problems with rsyslog has been it’s high memory usage, documented by many people in many complaints that can be found using google.

I’m interested in emulators, always have been, and I was wondering if anyone had used LLVM to write an emulator. I came across this highly detailed account which was a fun read: Statically Recompiling NES Games into Native Executables with LLVM and Go It concludes stating that static recompilation is probably less practical than JIT, …
I’m looking at keyboards as my BTC 6100C is starting to develop some key issues. I’ve been pretty happy with the 6100C but it’s not longer made and BTC is not making any wired compact keyboards at this time.
