Get Base64 encode file-data from Input Form
...
The easy way:
The readAsDataURL() method might already encode it as base64 for you. You'll probably need to strip out the beginning stuff (up to the first ,), but that's no biggie. This would take all the fun out though.
The hard way:
If you want to try it the hard way (or it doesn't work), loo...
mingw-w64 threads: posix vs win32
I'm installing mingw-w64 on Windows and there are two options: win32 threads and posix threads. I know what is the difference between win32 threads and pthreads but I don't understand what is the difference between these two options. I doubt that if I will choose posix threads it will prevent me fro...

Increase heap size in Java
I am working on a Windows 2003 server (64-bit) with 8 GB RAM. How can I increase the heap memory maximum? I am using the -Xmx1500m flag to increase the heap size to 1500 Mb. Can I increase the heap memory to 75% of physical memory (6 GB Heap)?

Base64: What is the worst possible increase in space usage?
If 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)?

How does Python manage int and long?
...hon 2: sys.maxint contains the maximum value a Python int can hold.
On a 64-bit Python 2.7, the size is 24 bytes. Check with sys.getsizeof().
Python 3: sys.maxsize contains the maximum size in bytes a Python int can be.
This will be gigabytes in 32 bits, and exabytes in 64 bits.
Such a large in...
