How to limit setAccessible to only “legitimate” uses?
..., if you mean "privacy" to encompass the meaning of protecting sensitive information from disclosure, you are barking up the wrong tree. The way to protect sensitive data in a Java application is not to allow untrusted code into the security sandbox that deals with sensitive data. Java access modi...
How to avoid reverse engineering of an APK file?
...r and device.
When storing values on the device, don't store them in a raw format. For example, if you have a game, and you're storing the amount of in game currency the user has in SharedPreferences. Let's assume it's 10000 coins. Instead of saving 10000 directly, save it using an algorithm like ((...
Why does base64 encoding require padding if the input length is not divisible by 3?
...s are concatenated, it's impossible to recover the original data because information about the number of odd bytes at the end of each individual sequence is lost. However, if padded sequences are used, there's no ambiguity, and the sequence as a whole can be decoded correctly.
Edit: An Illustration...
Where does Scala look for implicits?
...r implicits? I mean implicit because the question never seems to get fully formed, as if there weren't words for it. :-) For example, where do the values for integral below come from?

What is “rvalue reference for *this”?
...e the first example at the top of this post. After the aforementioned transformation, the overload-set looks something like this:
void f1(test&); // will only match lvalues, linked to 'void test::f() &'
void f2(test&&); // will only match rvalues, linked to 'void test::f() &&...
Why does C++ not have reflection?
...ndard
library relies on this aggressive
optimization. Functors are only
performant if the overhead of
instantiating and destructing the
object can be optimized away.
operator[] on a vector is only comparable to raw
array indexing in performance
because the entire operator can be
inlined and thus rem...
Fundamental difference between Hashing and Encryption algorithms
...w combines the resultant states from all these iterations back together to form the resultant hash.
Now, if you wanted to decode the hash, you'd first need to figure out how to split the given hash into its iterated states (1 possibility for inputs smaller than the size of a chunk of data, many for...
What encoding/code page is cmd.exe using?
...
@user200783, decomposed form isn't supported; usually one can transform to an NFC equivalent. Also, the console in Western locales doesn't allow mixing full-width and half-width glyphs. Also, when using codepage 65001 (UTF-8), prior to Windows 8 Wri...
C++ equivalent of java's instanceof
...inted out dynamic_cast doesn't come for free. A simple and consistently performing hack that handles most (but not all cases) is basically adding an enum representing all the possible types your class can have and check whether you got the right one.
