The birthday paradox observes that in a room of 23 people, the odds that at least two people share a birthday is 50% The same logic that drives matching birthdays also drives the probability that one can find collisions with a hash function.

(unless (equal "/" path) (file-name-directory (directory-file-name path)))) (defun ar/find-upwards....

In Charting the Waters , I mentioned two books that I picked up to get myself in the travel mindset. Last week, I set aside an hour and read through the lighter of the two: How to Drop Everything And Travel Around The World . Thoughts Overall, I thought the book was a worthwhile read. As far as actual, concrete information about travel and destinations, it was pretty light (the whole thing is only 56 pages), but it was cert..

The org table, in all its textful glory, looked as follows… | Date | Item | Charge | |------------------+----------------+----------| | [2015-06-18 Thu] | Cash | 20.00 | | [2015-07-11 Sat] | Lucky 7 | 42.97 | | [2015-07-13 Mon] | Santa....

Back again with another riveting installment of Questions and Answers. Mountain View has a car show during its Thursday Night Live series of events. Are you in that? Erm, no. Though if I ever go fully insane and paint the outside of the box with flames and other crazy shenanigans, I’ll definitely start attending some car shows.

In 2014 the White House commissioned a 90-day study that culminated in a report (pdf) on the state of “big data” and related technologies. The authors give many recommendations, including this central warning. Warning: algorithms can facilitate illegal discrimination! Here’s a not-so-imaginary example of the problem. A bank wants people to take loans with high interest rates, and it also serves ads for these loans. A modern idea is to use a..

Append the password prompt REGEXP: (setq comint-password-prompt-regexp (concat comint-password-prompt-regexp "\\|" "Password for red aler..
