What is the difference between the kernel space and the user space?

How to unstash only certain files?
... stash@{0} -- <filename>" restores the version of the file as of the time when the stash was performed -- it does NOT apply (just) the stashed changes for that file.

~x + ~y == ~(x + y) is always false?
...refore I would say code that makes that assumption is bad code most of the time. (Particularly when there are usually better ways of messing with signed numbers than bit twiddling; and particularly when unsigned numbers are probably a better choice most of the time anyway)

Split large string in n-size chunks in JavaScript
...hort strings (even with cached regex - probably due to regex parsing setup time)
match is even more inefficient for large chunk size (probably due to inability to "jump")
for longer strings with very small chunk size, match outperforms slice on older IE but still loses on all other systems

Make sure only a single instance of a program is running
...e running instance. For example when the users starts the program a second time, you could send the running instance a command to tell it to open another window (that's what Firefox does, for example. I don't know if they use TCP ports or named pipes or something like that, 'though).

Is it possible to print a variable's type in standard C++?
...is answer from Jamboree shows how to get the type name in C++14 at compile time. It is a brilliant solution for a couple reasons:
It's at compile time!
You get the compiler itself to do the job instead of a library (even a std::lib). This means more accurate results for the latest language featu...
How do shift operators work in Java? [duplicate]
...intln(Integer.toBinaryString(2 << 11));
Shifts binary 2(10) by 11 times to the left. Hence: 1000000000000
System.out.println(Integer.toBinaryString(2 << 22));
Shifts binary 2(10) by 22 times to the left. Hence : 100000000000000000000000
System.out.println(Integer.toBinaryString(2...
