“…each [Emacs] keystroke generates around 1◦ C thermal spike…”
Who knew? In their tests, the startup phase of Emacs raised the processor temperature in the area being measured (simulated) by 15◦ C. Most of what’s driving modern trends toward multicore architectures is the tendency for higher speed single core machines to run too hot. Indeed, I saw one presentation at IBM pointing out that heat densities were passing those found on the surface of a clothes iron! Anyway, this is an interesting paper if you’re interest in modern processor design.
