How do I replace the *first instance* of a string in .NET?
...dog";
str = ReplaceFirst(str, "brown", "quick");
EDIT: As @itsmatt mentioned, there's also Regex.Replace(String, String, Int32), which can do the same, but is probably more expensive at runtime, since it's utilizing a full featured parser where my method does one find and three string concatenati...
Deleting elements from std::set while iterating

2015.10.27 update:
C++11 has resolved the defect. iterator erase (const_iterator position); return an iterator to the element that follows the last element removed (or set::end, if the last element w...
.prop('checked',false) or .removeAttr('checked')?
...r attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).
So, either will work... but the second example you gave (using prop) i...
Select random row from a sqlite table
...t perfect : the distribution of probability is higher on the last row (the one with the highest rowid), but if you often add stuff to the table, it will become a moving target and the distribution of probabilities should be much better.
Yet another solution, if you often select random stuff from a ...

It will parse one line of items separated by ;, pushing it into an array. Stuff for processing whole of $IN, each time one line of input separated by ;:

Is it better to call ToList() or ToArray() in LINQ queries?
...tly to the number of elements.
To meet this constraint ToArray often does one more allocation than ToList. Once it has an array that is big enough it allocates an array which is exactly the correct size and copies the elements back into that array. The only time it can avoid this is when the grow...
