Interview question: Check if one string is a rotation of other string [closed]
...cription of the algorithm. Google seems to indicate that Java doesn't have fast string searching (see johannburkard.de/software/stringsearch for example) though I doubt it would break anything if they changed it.

Select random row from a sqlite table
...
The following solutions are much faster than anktastic's (the count(*) costs a lot, but if you can cache it, then the difference shouldn't be that big), which itself is much faster than the "order by random()" when you have a large number of rows, although t...
Mac OSX Lion DNS lookup order [closed]
...est showed up in the log file, and that once it did, the app itself was as fast as usual.
Now I have two lines per app, like this:
127.0.0.1 foo.bar.local
::1 foo.bar.local
... and everything is fast again.
Apparently this adds IPv6 addresses? I don't quite get it, really, but it works.

Accessing items in an collections.OrderedDict by index
...r do you specifically want a map-like type that's ordered in some way with fast positional indexing? If the latter, then consider one of Python's many sorted dict types (which orders key-value pairs based on key sort order). Some implementations also support fast indexing. For example, the sortedcon...
Calculate last day of month in JavaScript
...'s okay, I noticed the selected answer is suggesting the same. This is the fastest and most reliable way and works regardless of the type of the calendar. For example if Date implemented something other than the Gregorian calendar it would still work. See intldate.codeplex.com for an example of non-...

[Fast] Loop with std::getline()
The simplest approach is to open an std::ifstream and loop using std::getline() calls. The code is clean and easy to understand.

hash function for string
...ant to use a cryptographic hash for a hash table. An algorithm that's very fast by cryptographic standards is still excruciatingly slow by hash table standards.
Second, you want to ensure that every bit of the input can/will affect the result. One easy way to do that is to rotate the current result...
C++ : why bool is 8 bits long?
...nd a simple one bit on off bit via wireless. Sending one bit is extremelly fast and we need that signal to be as fast as possible."
Well, it was a test to see if I understood the concepts and bits, bytes, and error handling. How easy would it for a bad guy to send out a one bit msg. Or what happen...
