deltasquared··on Leadership, Strategy and Qt
Some aspects of a platform are not a challenge, just painful.

For instance say I am looking for a bit of text.

In *nix I have vi in which I can type "esc/foo." Now, before I can blink the I am at the first match. Hitting "/" goes to the next one just as fast. If I don't know what file to look at, grep will tell me quickly.

Visual Studio has a search function, but it's not regular expressions by default, will not work on all of the design surfaces, and requires going through several dialogue windows. Typically I have to put my hand on the mouse to get any results.

For some tasks platforms and tools can make a big speed difference.

However it is true people are complex and hard to predict.

Perhaps some c/c++/QT programmers when given a, a shiny new windows based development environment, may enjoy the extra time they spend searching through source code. Who knows?

deltasquared··on Haiku OS (BeOS clone)
Not to knock your comment, but BeOS R5 was released in 2001. That would make it a 10+ year old UI.
deltasquared··on Computer Science is Not Math
I read the article and disagree. Computer science is a discipline of applied mathematics.

Saying that computer science is not mathematics because it involves real world complications, is like saying that experimental physics isn't physics because it is not done by theorists.

Are you looking for something like Web Noir? http://webnoir.org/

This is a demo from a talk presented by Bret Victor. The full video is here: http://youtu.be/PUv66718DII
deltasquared··on Fun with math: Dividing one by 998001 yields a surprising result

  ;Here is my version in Common Lisp
  ;Supply your own flatten function
  ;or borrow one from let-over-lambda or something
  ;http://letoverlambda.com/lol.lisp

  (defun long-div (dividend divisor depth)
    (cond
     ((> depth 0)
      (flatten (list
                (truncate (/ dividend divisor))
                (long-div (* 10 (mod dividend divisor))     
                 divisor (- depth 1)))))
     (t ())))
deltasquared··on Can your REPL do this?
To run the demos from SBCL: (require 'asdf) (asdf:operate 'asdf:load-op 'academy) (in-package :academy) (help)

deltasquared··on Inspired by XKCD:903, Wikipedia steps to philosophy
Found a loop: Start at Reiki

reiki spiritual_practice spirituality reality being eastern_philosophy islamic_philosophy islamic_studies islamic_history history george_santayana madrid spain balearic_islands catalan_language uh oh... found a loop

spain -> balearic_islands -> catalan_language -> spain .

So this game is traversing a cyclic graph. It should be possible to get around this by keeping track of visited links, and not repeating our clicks.

Now is Wikipedia a connected graph?
