Can (a== 1 && a ==2 && a==3) ever evaluate to true?
Moderator note: Please resist the urge to edit the code or remove this notice. The pattern of whitespace may be part of the question and therefore should not be tampered with unnecessarily. If you are in the "whitespace is insignificant" camp, you should be able to accept the code as is. Is it ever possible that (a== 1 && a ==2 && a==3) could evaluate to true in JavaScript? This is an interview qu
Circle drawing with SVG's arc path
Using SVG path, we can draw 99.99% of a circle and it shows up, but when it is 99.99999999% of a circle, then the circle won't show up. How can it be fixed? The following SVG path can draw 99.99% of a circle: var paper = Raphael(0, 0, 300, 800); // Note that there are supposed to be 4 arcs drawn, but you may see only 1, 2, or 3 arcs depending on which browser you use paper.path("M 100 100 a 50 50
How can I debug git/git-shell related problems?
How can I have some debug information regarding git/git-shell? I had a problem, that user1 could clone a repository without problem, while user2 could clone only an empty one.

An appropriate error message could short-circuit this problem.

Git Bash is extremely slow on Windows 7 x64
I've been using Git on both Windows and Ubuntu during the development of a small project, frequently flipping back and forth between the two. The issue is that Git Bash consistently becomes slow. When I say slow, I mean that running cd takes anywhere from 8-25 seconds, running git commands take from 5-20 seconds, and ls can take up to 30 seconds sometimes. Needless to say, this is not fun, not to
Why is printing "B" dramatically slower than printing "#"?
I generated two matrices of 1000 x 1000: First Matrix: O and #. Second Matrix: O and B. Using the following code, the first matrix took 8.52 seconds to complete: Random r = new Random(); for (int i = 0; i < 1000; i++) { for (int j = 0; j < 1000; j++) { if (r.nextInt(4) == 0) { System.out.print("O"); } else { System.out.print("#"); } } System.out.println(""); } With this code, the second matrix too
