I'm going to run SHA256 on a password + salt, but I don't know how long to make my VARCHAR when setting up the mysql database. What is a good length?

A sha256 is 256 bits longs....
It should be 64 characters.
Wrong SHA algorithm sorry.
It's always 64 characters, which can be determined by running anything into one of the online SHA-256 calculators .
Why would you make it VARCHAR? It doesn't vary.

For example, I have:
long long veryLong = // assume value here NSLog(@"%f", veryLong); // of course wrong...

unsigned long long int num = 285212672; //FYI: fits in 29 bits

return 0;
}

Trouble as long, unsigned long long etc, since you don't have to guess how many bits are in eachUse the ll (el-el) long-long modifier with the u (unsigned) conversion.

Suppose I have one long long int and want to take its bits and construct four unsigned short ints out of it.
Particular order doesn't matter much here.
I generally know that I need to shift bits and truncate to the size of unsigned short int. But I think...

When the visitor goes to a webpage, how do we know the visitor is actually showing the page on top (instead of going to another tab or app already).
also how do we know how long the user has read the page or how long the page stayed open?

<rant> Frankly, why do you need to know? How long it takes me to understand what you write? How long I went to lunch? Is total surveillance of your visitors a Good Thing.

I would like to know how long it's taking to send a message to an object with at least a 1ms accuracy. How do I do this?
