Does “display:none” prevent an image from loading?
...of your browser's developer tools.
Note that if the browser is on a small CPU computer, not having to render the image (and layout the page) will make the whole rendering operation faster but I doubt this is something that really makes sense today.
If you want to prevent the image from loading you...

What platforms have something other than 8-bit char?
....
For instance, most early-90s developers assumed that a particular no-op CPU timing delay taking a fixed number of cycles would take a fixed amount of clock time, because most consumer CPUs were roughly equivalent in power. Unfortunately, computers got faster very quickly. This spawned the rise of...
Generating random integer from a range
...ate tens of millions of random numbers in less than a second on a standard CPU with this technique.
EDIT:
Although the above is technically correct, DSimon's answer is probably more useful in practice. You shouldn't implement this stuff yourself. I have seen a lot of implementations of rejection s...

I hope you haven't paid $50000 pr CPU for Oracle Enterprise, and then only used the least common denominator in order to switch to Mysql any minute. As any good DBA will tell you, there are subtle differences between the different big name databases, especial...
What integer hash function are good that accepts an integer hash key?
... input results in a different output). The algorithm is fast except if the CPU doesn't have a built-in integer multiplication unit. C code, assuming int is 32 bit (for Java, replace >> with >>> and remove unsigned):

IMHO, if you know a way of doing it with less cpu usage (and thus less power drain), there is no reason not to use it.

Difference between malloc and calloc?
... do some tricks to speed it up. I know that FreeBSD, when it gets any idle CPU time, uses that to run a simple process that just goes around and zeroes out deallocated blocks of memory, and marks blocks thus processes with a flag. So when you do calloc, it first tries to find one of such pre-zeroed ...
