What is the difference between LR, SLR, and LALR parsers?
...

SLR, LALR and LR parsers can all be implemented using exactly the same table-driven machinery.
Fundamentally, the parsing algorit...
The Use of Multiple JFrames: Good or Bad Practice? [closed]
...d say a JFrame needs more space than a JInternalFrame, even if you open up 100 JFrames, how many more resources would you really be consuming? If your concern is memory leaks because of resources: calling dispose() frees all resources used by the frame for garbage collection (and, again I say, a JIn...
How can I exclude all “permission denied” messages from “find”?

Note:
* This answer probably goes deeper than the use case warrants, and find 2>/dev/null may be good enough in many situations. ...
OPTION (RECOMPILE) is Always Faster; Why?
...e there are 10 records in your database and then execute it when there are 100,000,000 records the cached execution plan may no longer be the most effective.
In summary - I don't see any reason that OPTION(RECOMPILE) would be a benefit here. I suspect you just need to update your statistics and yo...

Nearest neighbors in high-dimensional data?
... grams rather than kilograms, then the original value of 86.1, would be 86,100, which would have a large effect on your results, which is exactly what you don't want. Probably the most common scaling technique is subtracting the mean and dividing by the standard deviation (mean and sd refer calculat...
How expensive is RTTI?
...elp.
I was doing a quick test using this:
GCC Clock() + XCode's Profiler.
100,000,000 loop iterations.
2 x 2.66 GHz Dual-Core Intel Xeon.
The class in question is derived from a single base class.
typeid().name() returns "N12fastdelegate13FastDelegate1IivEE"
5 Cases were tested:
1) dynamic_cast<...
Why do people say there is modulo bias when using a random number generator?
...andom bits yields 8 possible outcomes:
000 = 0, 001 = 1, 010 = 2, 011 = 3
100 = 4, 101 = 5, 110 = 6, 111 = 7
We can reduce the size of the outcome set to exactly 6 by taking the value modulo 6, however this presents the modulo bias problem: 110 yields a 0, and 111 yields a 1. This die is loaded.

I know, it was discussed already 1000 times, but I can't adjust the text size for different screen sizes. I try to use 'sp' as size units in my custom style:
