Trust me, I’m pretty happy with that old good Mojave and the full iTunes!

Evolution of Emacs Lisp (PDF, 55 pp.). #emacs

Yes, make Emacs appealing and user friendly. But don’t forget that a masterful tool in the end requires mastery, which can’t come for free. I certainly draw the line at saying Emacs is for everyone. I’m not saying it’s only for some sort of snooty “elite” but I am saying that it’s for those who are willing to learn, seeing some extra work as the aforementioned long-term investment, and who have the patience reach a worthy goal a little later rather than right this very minute. — Making Emacs popular again

Always demand a deadline. A deadline weeds out the extraneous and the ordinary. It prevents you from trying to make it perfect, so you have to make it different. Different is better. — 68 Bits of Unsolicited Advice

What scientists must know about hardware to write fast code. #julia

Programming is used in many fields of science today, where individual scientists often have to write custom code for their own projects. For most scientists, however, computer science is not their field of expertise; They have learned programming by necessity.

Emacs as a Shell. #emacs

Re-reading my old TODO lists, I noticed I bookmarked agate long ago. The showcase is awesome, especially regarding quick drawing facilities (including facetting & co.). #python

Iterated random functions are used to draw pictures or simulate large Ising models, among other applications. They offer a method for studying the steady state distribution of a Markov chain, and give useful bounds on rates of convergence in a variety of examples. The present paper surveys the field and presents some new examples. There is a simple unifying idea: the iterates of random Lipschitz functions converge if the functions are contracting on the average. — Iterated Random Functions, by Diaconis and Freedman

Sounds already good to me.
