My trip to Italy last year was the first time I’d ever been overseas. Most of the trip was spent walking across Tuscany and Umbria.

If you’re familiar with nearly any mainstream programming language, and I asked you to draw a diagram of an array, the array indices, and the array elements, odds are good you’d produce a diagram something like this: In this post, I want to persuade you to replace that image, or, at least, to augment it with an alternate view on the world. I want to argue that, rather than numbering elements of an array, it makes just as much sense, and in ..

One of the things that has always bothered me about searchcode.com was that it never generated any money. Not a huge problem in itself as a side project, but the costs to run it are not insignificant due to the server requirements. I had looked into soliciting donations but I considered this highly unlikely to produce enough revenue to cover costs considering that sites such as gwern.net was unable to make enough to cover even basic costs..

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. In other words, if you have a uniform hashing function that outputs a value between 1 and 365 for any input, the probability that two hashes would collide in a set of 23 values is also 50% Another....

Whether it's Makefile, SConstruct, BUILD, or your favorite build file, chances are you have to tweak it from time to time. ar/open-build-file searches your current and parent directories to find a build file. (defvar ar/project-file-names '("Makefile" "SConstruct" "BUILD")) (defun ar/parent-directory (path) "Get parent directory for PATH." (unless (equal "/" path) (file-name-directory (directory-file-name path)))) (defun ar/find-upwards....

Fixing regression bugs is analogous to digging a hole only to find the next day it has been filled in and having to dig it out again” Ask any manager, developer or tester working on software without tests what the main pain points are. Nearly all the time the main one mentioned is dealing with regressions. This is bugs that were fixed a year ago which returned. Regression bugs cost the software industry billions of dollars a year. Worse..

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..

Recently kept track of expenses between a group of us. To settle the scores, I emailed an exported HTML table from an org file. This was simple enough and required no external viewer from recepients. 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. I could go the full nine yards, get an amp and put a sound system in the back, maybe a disco ball or two. ..

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..

At some point, you may come across a trusted command-line utility prompting you for a password, and Emacs shell happily displaying each typed character to the nearby-world to see. Luckily, you can train Emacs to recognize new password prompts and hide the typed characters in modes deriving from comint. Append the password prompt REGEXP: (setq comint-password-prompt-regexp (concat comint-password-prompt-regexp "\\|" "Password for red aler..
