Patti Smith, Horses.

Euler problem 14 is all about Collatz numbers. I am aware of Atabey Kaygun’s posts, but I found a nice implementation in Scheme on SO today.

The temperatures are milder this week and yet I have 10/6 BP. Thanks for the medication! However, I should note that I am no longer stressed in the evening because of–you know–things to do urgently at the last minute. Because I no longer care, above all.

The Riemann Hypothesis Says 5040 is the Last. #math

The Implementation of Functional Programming Languages.

I’m all in LSP stuff at the moment, but maybe I should give it a try: An interface to communicate with Jupyter kernels. #emacs

Better Than Floating Point? on HN today. The comments are also full of extra links on FP computation.

C in four functions. See also Let’s Build a Compiler. #clang

Best way I found to mimic R’s rle function is this nice little piece of code (in Racket; credit to Chris Jester-Young):

(define (bagify lst)
  (foldl (lambda (key ht)
           (hash-update ht key add1 0))
         #hash() lst))

Now, it’s probably time to go watch Taken (once again).
