Mathematical functions in Swift
...re currently available on Float and Double and it should be easy enough to convert to a CGFloat for example.
Instead of sqrt() there's the squareRoot() method on the FloatingPoint protocol. Again, both Float and Double conform to the FloatingPoint protocol:
let x = 4.0
let y = x.squareRoot()

SQL how to make null values come last when sorting ascending
...using the method for ints above:
SELECT *
FROM Employees
ORDER BY ISNULL(CONVERT(INT, HireDate)*0, 1), HireDate
(Lets pretend the schema has HireDate.)
These methods avoid the issue of having to come up with or manage a "maximum" value of every type or fix queries if the data type (and the maxi...
How do I use arrays in C++?
...ly "connection" between T[n] and T[m] is that both types can implicitly be converted to T*, and the result of this conversion is a pointer to the first element of the array. That is, anywhere a T* is required, you can provide a T[n], and the compiler will silently provide that pointer:

How do I get the type of a variable?
... use either myClassA or myClassB type. On a mismatch, I need to spend time converting the data.
switch ((typeid(T)) {
case typeid(myClassA):
// handle that case
break;
case typeid(myClassB):
// handle that case
break;
case typeid(uint32_t):
// handle that case

Base64: What is the worst possible increase in space usage?
...f a server received a base64 string and wanted to check it's length before converting,, say it wanted to always permit the final byte array to be 16KB. How big could a 16KB byte array possibly become when converted to a Base64 string (assuming one byte per character)?
