Simple way to encode a string according to a password?
... repetition. Including the iteration count ensures that you can adjust for CPU performance increases over time without losing the ability to decrypt older messages.
A password alone can be as safe as a Fernet 32-byte random key, provided you generate a properly random password from a similar size ...
What is the strict aliasing rule?
...ut aliasing, it can omit those instructions, load buff[0] and buff[1] into CPU registers once before the loop is run, and speed up the body of the loop. Before strict aliasing was introduced, the compiler had to live in a state of paranoia that the contents of buff could change at anytime from anywh...
Fastest way to determine if an integer's square root is an integer
...that works ~35% faster than your 6bits+Carmack+sqrt code, at least with my CPU (x86) and programming language (C/C++). Your results may vary, especially because I don't know how the Java factor will play out.
My approach is threefold:
First, filter out obvious answers. This includes negative nu...

What is state-of-the-art for text rendering in OpenGL as of version 4.1? [closed]
...GPU, but it is much easier and more efficient to that kind of thing on the CPU, as it is a strictly sequential operation and not at all trivial (think of kerning). Also, it would need another feedback pass, which would be another sync point.
Render the previously generated data from the feedback buf...
Why does this loop produce “warning: iteration 3u invokes undefined behavior” and output more than 4
...ause non-conforming programs to no
longer work as expected, such as SPEC CPU 2006 464.h264ref and
416.gamess. A new option, -fno-aggressive-loop-optimizations, was added to disable this aggressive analysis. In some loops that have
known constant number of iterations, but undefined behavior is ...
How to make an OpenGL rendering context with transparent background?
...tions. Copying GPU data to the RAM for each frame is very demanding on the CPU, resulting in low FPS. Check the comments on this answer: stackoverflow.com/questions/4780756/…

How do I print a list of “Build Settings” in Xcode project?
...lue but you can't just pick one— dupe values on one platform/build-level/CPU-type/programming-language/etc. combo may differ with another combo. The official docs have their purpose, even if they could serve that purpose more fully.
