What is the difference between user and kernel modes in operating systems?
...or reference memory. Code
running in user mode must delegate to
system APIs to access hardware or
memory. Due to the protection afforded
by this sort of isolation, crashes in
user mode are always recoverable. Most
of the code running on your computer
will execute in user mode.

These types can also take advantage of calling unexported between them which keeps the API small and clear.
Group related types and code together in each file. If your types and functions are well or...

I wish to calculate the time it took for an API to return a value.
The time taken for such an action is in the space of nano seconds. As the API is a C++ class/function, I am using the timer.h to caculate the same:

Run javascript function when user finishes typing instead of on key up?
...
I would not recommend this. The code triggers an API request each time a key is pressed. Then it cancels the request if another key is pressed. Even though this solution prevents the AJAX callback to be triggered while the user types, it will still hammer the server with re...
