SQLite with encryption/password protection
...testing, I've found that the SetPassword method (at this time) appears basically useless. The only way I was able to get the System.Data.SQLite library to properly apply the password was using the ChangePassword method. Using SetPassword (before calling the Open method, as is apparently required by ...
What's the best CRLF (carriage return, line feed) handling strategy with Git?
...n answer that completely satisfies me!
See the details in github:help's guide to
Dealing with line endings.
Git allows you to set the line ending properties for a

Arrow operator (->) usage in C
I am reading a book called "Teach Yourself C in 21 Days" (I have already learned Java and C# so I am moving at a much faster pace). I was reading the chapter on pointers and the -> (arrow) operator came up without explanation. I think that it is used to call members and functions (like the eq...
Why do we usually use || over |? What is the difference?
...onsider the following example.
Boolean b = true;
if(b || foo.timeConsumingCall())
{
//we entered without calling timeConsumingCall()
}
Another benefit, as Jeremy and Peter mentioned, for short-circuiting is the null reference check:
if(string != null && string.isEmpty())
{
//we c...
List passed by ref - help me explain this behaviour
...list, but your aren't passing the list variable by reference - so when you call ChangeList the value of the variable (i.e. the reference - think "pointer") is copied - and changes to the value of the parameter inside ChangeList aren't seen by TestMethod.
try:
private void ChangeList(ref List<in...
Java 32-bit vs 64-bit compatibility
...VM rather than a 32bit VM and didn't notice until some external libraries (called by JNI) started failing.
Data serialized on a 32bit platform was read in on the 64bit platform with no issues at all.
What sort of issues are you getting? Do some things work and not others? Have you tried attaching ...
Is it better in C++ to pass by value or pass by constant reference?
... figure out when passing by value is expensive, and implicitly convert the call to use a const ref if possible.
In theory. In practice, compilers can’t always change this without breaking the function’s binary interface. In some special cases (when the function is inlined) the copy will actuall...
Deep copying an NSArray
