Java compile speed vs Scala compile speed
...scala type system is way more complicated than Java's and hence takes more CPU time.
Type inference - type inference is computationally expensive and a job that javac does not need to do at all
scalac includes an 8-bit simulator of a fully armed and operational battle station, viewable using the mag...
Why main does not return 0 here?
...return value from a function is normally stored in the eax register of the cpu, so the statement "return 4;" would usually compile to
mov eax, 4;
ret;
and return x (depending on your compiler) would be something like:
mov eax, [ebp + 4];
ret;
if you don't specify a return value then the compil...
How can I be notified when an element is added to the page?
... here. Seriously. Don't poll the DOM every 100 milliseconds; it will waste CPU power and your users will hate you.
Since mutation events were deprecated in 2012, and you have no control over the inserted elements because they are added by someone else's code, your only option is to continuously che...
How to destroy an object?
...for "speed", but if you want to reclaim memory immediately (at the cost of CPU) should want to use null.
Like others mentioned, setting to null doesn't mean everything is reclaimed, you can have shared memory (uncloned) objects that will prevent destruction of the object. Moreover, like others h...

JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images
...) > -1, because it's faster and less resource intensive (both RAM & CPU). There's no need to have an array there. This is important when batching lots of images, where every bit count. Otherwise, pretty good answer. Upvoted!

List directory in Go
...ter implementations use more memory. It's also possible that the number of CPU cores on the tester's computer hurts/helps the concurrent filepath.Walk. Furthermore, filepath.Walk supports recursive decent while os.File.Readdir and ioutil.ReadDir do not.
