Editing dictionary values in a foreach loop
I am trying to build a pie chart from a dictionary. Before I display the pie chart, I want to tidy up the data. I'm removing any pie slices that would be less than 5% of the pie and putting them in a "Other" pie slice. However I'm getting a Collection was modified; enumeration operation may not exe...
Failure [INSTALL_FAILED_ALREADY_EXISTS] when I tried to update my application
...
adb install -r does not always work (I've got an EVO 4G from Sprint that refuses to behave as expected). The only work around I've found is to remove the application manually. Sometimes, I even have to do it through the phone's UI because the EVO is so temperamental.

...umes it's circular. Otherwise, this should work. I even used areEquivalent from here, but JSON.Stringify still throws the exception after 30 iterations. Still, it's good enough to get a decent representation of the object at a top level, if you really need it. Perhaps somebody can improve upon this ...
Why would I ever use push_back instead of emplace_back?
... constructors are supposed to be safe. If you can implicitly construct a U from a T, you are saying that U can hold all of the information in T with no loss. It is safe in pretty much any situation to pass a T and no one will mind if you make it a U instead. A good example of an implicit constructor...
Is short-circuiting logical operators mandated? And evaluation order?
... @Joe: but return value and arguments of the operator may change from boolean to something else. I used to implement "special" logic with THREE values ("true", "false" and "unknown"). Return value is deterministic, but short-circuiting behaviour is not appropriate.

CMake: Project structure with unit tests

For questions 1 & 2, I would recommend making a library from your non-test files excluding main.cpp (in this case just src/sqr.cpp and src/sqr.h), and then you can avoid listing (and more importantly re-compiling) all the sources twice.
For question 3, these commands add a test c...
