Are these jQuery expressions equivalent?
I'm wondering if these two expressions are equivalent, because if they are, it would make this much easier. $('div', this).filter(':not(.trigger)')... $('div:not([class*=trigger])', this)... (this providing a context under which to look for the specified div) ...

For example, int a = (10,20) ; when given in global scope yields an error "initializer is not a constant", though both the expressions separated by a comma operator are constants (constant expressions). Why is th...
Expression Encoder 3: Green artifacts after encoding
Some of the videos I encode using the Expression Encoder 3.0 have green lines at the bottom. Since I have no prior experience with encoding, I have no clue about why this is happening. Though I think it might have something to do with the format of the videos I am encoding. I am using some very basic code: DirectoryInfo dInfo = new Dire...
Embed a JQuery expression inside a css file??
As the question implies, can I add a JQuery script inside an css file as an expression? Or something like: .parent{ background-color: pink; position:relative; width: 100%; } .child{ position: absolute; background: transparent url('./background.gif') no-repeat top right; /*height: 100%;*/ height: expression($(this).parent.height...
Do all parts of a SQL SERVER expression using 'OR' get evaluated?
Given: WHERE (@Id Is NULL OR @Id = Table.Id) If @Id is null: the expression evaluates to true. Does the second part @Id = Table.Id still get considered? or is it sufficient that the expression evaluates to true given that the first part is (which is the case in c#). This is relevant because of some much more complex OR statements whe...

php - regex hostname extraction
I have been looking around for a regex expression that will spit out just the 'stackoverflow' part and no www. or .com etc. All I could find was to check if the url's were valid...

PowerShell: how *exactly* does the RHS of the -f operator work?
Last time I got confused by the way PowerShell eagerly unrolls collections, Keith summarized its heuristic like so: Putting the results (an array) within a grouping expression (or subexpression e.g. $()) makes it eligible again for unrolling. I've taken that advice to heart, but still find myself unable to explain a few esoterica. ...

Disjunctive normal form with range predicate
Hey! I need a library/algorithm that can transform an arbitrary logical expression that contains range predicates into a reduced disjoint normal form. Example : (x > 40) & ( (x > 50) | (y > 10)) -> (x > 50) | (x > 40) & (y > 10) Basically, what I want to simply such an expression in order to evaluated as fast as possible. Anyone c...

In perl I can do this: $number = qr/ zero | one | two | three | four | five | six | seven | eight | nine /ix; $foo = qr/ quantity: \s* $number /ix; My actual regular expression is many lines and does two-digit and ordinal numbers (e.g., "twenty-two", "forty-fourth" and "twelve are all complete matches), and I use it in several places....
