What is 'Context' on Android?
...place the UI that the user interacts with'.
Developers familiar with other APIs and even non-developers might think of it vernacularly as a “screen.” That’s technically inaccurate, but it doesn’t matter for our purposes. So how do Activity and Context interact and what exactly is going in th...
What's the rationale for null terminated strings?
...very low level. They are not library calls, but system calls. And the same API is used
for binary or text files. File reading primitives get a buffer address and a size and return
the new size. And you can use strings as the buffer to write. Using another kind of string
representation would imply yo...
Assigning out/ref parameters in Moq
...er Moq callbacks. And hacky because it relies on calling some internal Moq APIs via reflection.
The extension method provided at the above link didn't compile for me, so I've provided an edited version below. You'll need to create a signature for each number of input parameters you have; I've provi...

With bubbling, t...
If i synchronized two methods on the same class, can they run simultaneously?
...round an internal entity known as the intrinsic lock or monitor lock. (The API specification often refers to this entity simply as a "monitor.") Intrinsic locks play a role in both aspects of synchronization: enforcing exclusive access to an object's state and establishing happens-before relationshi...
Get query from java.sql.PreparedStatement [duplicate]
...
This is nowhere definied in the JDBC API contract, but if you're lucky, the JDBC driver in question may return the complete SQL by just calling PreparedStatement#toString(). I.e.
System.out.println(preparedStatement);
To my experience, the ones which do so ar...
When should you branch?
... same branch than your current development branch (because you would break API, or introduce code that would break everything), then you need a another branch.
