Are there any SHA-256 javascript implementations that are generally considered trustworthy?
...ypto in JS isn't really as well-vetted an endeavor as other implementation platforms, this one is at least partially developed by, and to a certain extent sponsored by, Dan Boneh, who is a well-established and trusted name in cryptography, and means that the project has some oversight by someone who...
How should I call 3 functions in order to execute them one after the other?

What happens to a detached thread when main() exits?
...t. AFAIK, exotic process and threading models are usually found on ancient platforms (to which C++11 probably won't be ported) and various embedded systems, which could have a special and/or limited language library implementation and also limited language support.

Some additional discussion, possibly dated, can be found in "Java¿ Platform Performance: Strategies and Tactics", 2000, by Steve Wilson and Jeff Kesselman, in section "9.2: Examining JNI costs". It's about a third of the way down this page, provided in the comment by @Philip below.

What exactly do “u” and “r” string flags do, and what are raw string literals?
...dows file paths (with backslashes instead of regular slashes like on other platforms), but that's very rarely needed (since normal slashes mostly work fine on Windows too) and imperfect (due to the "except" clause above).

How to set the maximum memory usage for JVM?
...es. It depends on what your application is doing.
That said, depending on platform, you may be able to do use some mechanism, ulimit for example, to limit the size of a java or any other process.
Just don't expect it to fail gracefully if it hits that limit. Native memory allocation failures are m...
Android update activity UI from service

RxJava provides canned (and cross-platform) scheduling, and easy composition of sequential asynchronous operations.
This should be more efficient than using a LocalBroadcast, though the overhead of using RxJava may outweigh that.
Some example code. First th...
