When trying to find out if a number is even or odd: AND 1 or OR 0
I recently learned of the trick for finding out if a binary number is odd or even.

Bitwise operation on uppercase ASCII character turns to lowercase. Why?
I came across this in the http_parser library of node.js implementation. When I bitwise-OR an ASCII capitalized character code, it converts into its lowercase version. The lowercase version remains as it is.

How were assemblers created straight from binary? [duplicate]
This question already has answers here: Were the first assemblers written in machine code? (11 answers) Closed 9 years ago. How did these earlier programmers know what combinations of binary produced certain results? Is there a way I can create an assembler from binary today? binary assembly 1 Every microprocessor has an instruction set. Each […]
Optimal data structure for binary data/Java
I have several input formats mostly restricted to geotiff and some proprietary binary formats. I import them into my program and then need to export them into various other data formats (also binary) but as two dimensional arrays.
Why aren’t “fat binaries” more widely used for cross-platform applications?
As far as I know, so-called “fat binaries”–executable files that contain machine code for multiple systems–are only really used on Apple PCs, and even there it seems like they only used them because they needed to transition from PowerPC to x86.
