Memory access on the Apple M1 processor

When a program is mostly just accessing memory randomly, a standard cost model is to count the number of distinct random accesses. The general idea is that memory access is much slower than most other computational tasks.

How to Navigate Emacs using Evil Mode

Emacs Evil mode is an extensible Vi layer for Emacs. It adds a set of Vi(m) key bindings and features to Emacs to give it a more modal feel, and lets you rely less on the pinky-accessed CTRL key when manipulating text. Where Emacs uses more key combinations and commands, Evil mode brings Vi’s operators and motions to execute text operations.

Midnight Sun: A novel

He calls himself Ulf—as good a name as any, he thinks—and the only thing he’s looking for is a place where he won’t be found by Oslo’s most notorious drug lord: the Fisherman. He was once the Fisherman’s fixer, but after betraying him, Ulf is now the one his former boss needs fixed—which may not be a problem for a man whose criminal reach is boundless. When Ulf gets off the bus in Kåsund, on Norway’s far northeastern border, he sees a “flat, monotonous, bleak landscape . . . the perfect hiding place. Hopefully.”

In the evening I started in Midnight Sun: A novel by Jo Nesbø. This is the sequel to the excellent Blood on Snow so I have high expectations.
