Event binding on dynamically created elements?
...ower overhead when many elements must be monitored. On a data table with 1,000 rows in its tbody, the first code example attaches a handler to 1,000 elements.
A delegated-events approach (the second code example) attaches an event handler to only one element, the tbody, and the event only needs to ...
Seeding the random number generator in Javascript
...nswer.)
var seed = 1;
function random() {
var x = Math.sin(seed++) * 10000;
return x - Math.floor(x);
}
You can set seed to be any number, just avoid zero (or any multiple of Math.PI).
The elegance of this solution, in my opinion, comes from the lack of any "magic" numbers (besides 10000...

What is dynamic programming? [closed]
... problem easier.
A good example is solving the Fibonacci sequence for n=1,000,002.
This will be a very long process, but what if I give you the results for n=1,000,000 and n=1,000,001? Suddenly the problem just became more manageable.
Dynamic programming is used a lot in string problems, such as ...
Validating IPv4 addresses with regexp
... this is the most accurate and strict regex, it doesn't accept things like 000.021.01.0. it seems like most other answers here do and require additional regex to reject cases similar to that one - i.e. 0 starting numbers and an ip that ends with a .

Unique random string generation
...s is pseudo-random, given the initial state one can predict up to next 250 000 GUIDs returned by the function UuidCreate. This is why GUIDs should not be used in cryptography, e. g., as random keys.
Instead, just use the C# Random method. Something like this (code found here):
