Custom CSS Scrollbar for Firefox
...and has loads of parameters you can tweak, but it ended up being a bit too CPU intensive for me (and it adds a fair amount to the DOM).
Now I'm giving Perfect Scrollbar a go. It's simple and lightweight (6KB) and it's doing a decent job so far. It's not CPU intensive at all (as far as I can tell) a...
Why are elementwise additions much faster in separate loops than in a combined loop?
...
OK, the right answer definitely has to do something with the CPU cache. But to use the cache argument can be quite difficult, especially without data.
There are many answers, that led to a lot of discussion, but let's face it: Cache issues can be very complex and are not one dimension...
Asynchronous vs synchronous execution, what does it really mean? [closed]
...tart and end points of tasks A, B, C represented by <, > characters.
CPU time slices represented by vertical bars |
Technically, the concept of synchronous/asynchronous really does not have anything to do with threads. Although, in general, it is unusual to find asynchronous tasks running on...
Why shouldn't I use PyPy over CPython if PyPy is 6.3 times faster?
... relevant, hardly anyone would run raytracing in a scripting language on a CPU these days. I did find pybenchmarks.org

Why are only a few video games written in Java? [closed]
... best with:
The biggest problem is that Java is really slow. On a pure cpu / memory / display / communications level, most modern cell phones should be considerably better gaming platforms than a Game Boy Advanced. With Java, on most phones you are left with about the CPU power of an original 4....
What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...han 32-bit? I always thought if there's less bits, there will be less bits CPU has to work on, thus faster. What am I missing here?

How can I build a small operating system on an old desktop computer? [closed]
... you suggest any references to building those?
anything that isn't direct cpu/memory operations. Anything that isn't directly in the CPU reference manual.
After the booting sequence--then what? How do I get into protected mode etc.
Protected mode will be part of the boot sequence.

To run your unit tests with code coverage analysis, try this:

Performance differences between debug and release builds
... method. This is a big one, it makes property accessors essentially free.
CPU register allocation. Local variables and method arguments can stay stored in a CPU register without ever (or less frequently) being stored back to the stack frame. This is a big one, notable for making debugging optimiz...
Which is faster: while(1) or while(2)?
...story is:
There exists a layer of translation between C++ source code and CPU instructions, and this layer has important implications for performance.
Therefore, performance cannot be evaluated by only looking at source code.
The compiler should be smart enough to optimize such trivial cases. Progr...
