Almost booting an iOS kernel in QEMU

Serverless QBasic
My first exposure to programming was on an HP-85 . This must have been around 1992 or 1993; the machine was then already largely obsolete, having been first produced in 1980.

Basics of Futexes
The futex (short for "Fast userspace mutex") mechanism was proposed by Linux contributors from IBM in 2002 [1] ; it was integrated into the kernel in late 2003. The main idea is to enable a more efficient way for userspace code to synchronize multiple threads, with minimal kernel involvement.
