Using bitwise OR 0 to floor a number
...twise operations except unsigned right shift, >>>, work on signed 32-bit integers. So using bitwise operations will convert a float to an integer.
Does it have any advantages over doing Math.floor? Maybe it's a bit
faster? (pun not intended)

System.BadImageFormatException: Could not load file or assembly (from installutil.exe)
...e most common reason for this exception these days is attempting to load a 32 bit-specific (/platform:x86) DLL into a process that is 64 bit or vice versa (viz. load a 64 bit-specific (/platform:x64) DLL into a process that is 32 bit). If your platform is non-specific (/platform:AnyCpu), this won't ...

How to convert an IPv4 address into a integer in C#?
...
32-bit unsigned integers are IPv4 addresses. Meanwhile, the IPAddress.Address property, while deprecated, is an Int64 that returns the unsigned 32-bit value of the IPv4 address (the catch is, it's in network byte order, so yo...

Targeting both 32bit and 64bit with Visual Studio in same solution/project
... as it pulls off the basic trick involved (create a common MSI, as well as 32-bit and 64-bit specific MSIs, and use an .EXE setup launcher to extract the right version and do the required fixups at runtime) very, very well.
You can probably achieve the same results using other tools or the Window...

Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?
...feated if it wasn't done that way.
This way you can write fast code using 32-bit values in 64-bit mode without having to explicitly break dependencies all the time. Without this behaviour, every single 32-bit instruction in 64-bit mode would have to wait on something that happened before, even thou...
Why is Java's boolean primitive size not defined?
...
Short answer: yes, boolean values are manipulated as 32-bit entities, but arrays of booleans use 1 byte per element.
Longer answer: the JVM uses a 32-bit stack cell, used to hold local variables, method arguments, and expression values. Primitives that are smaller than 1 cell ...
