CUDA. Concurrency is not parallelism. Andrew Gerrand 16 January 2013 If there’s one thing most people know about Go, is that it is designed for concurrency. No introduction to Go is complete without a demonstration of its goroutines and channels. But when people hear the word concurrency they often think of parallelism, a related but quite distinct concept. In programming, concurrency is the composition of independently executing processes, while parallelism is the simultaneous execution of (possibly related) computations. Concurrency is about dealing with lots of things at once. To clear up this conflation, Rob Pike gave a talk at Heroku’s Waza conference entitled Concurrency is not parallelism, and a video recording of the talk was released a few months ago. The slides are available at go.dev/talks (use the left and right arrow keys to navigate). To learn about Go’s concurrency primitives, watch Go concurrency patterns (slides). Exploring Emacs. Here's a fun idea in case you want to practice reading code and using Emacs: read Emacs in Emacs!
Emacs makes it easy to see the code behind its commands. For instance, if you want to see how a particular command-key sequence works, type C-h k and then the key sequence into the modeline prompt. If you're curious how C-h k itself works, type C-h k C-h k. According to the *Help* buffer that appears, C-h k corresponds to the Emacs Lisp function describe-key defined in help.el. Move your cursor onto the help.el text in the Help buffer and press enter. You're now looking at the Emacs Lisp source for describe-key. If you'd like to see how a particular Emacs Lisp function or special form works, type C-h f and then the name of the function or special form. Perhaps you're curious how lambda works: type C-h f lambda and then hit enter. Emacs isn't Emacs Lisp all the way down, though.
It's fun to guess whether a particular function or special form is defined in Emacs Lisp or C.
