An NSAssert will throw an exception when it fails. So NSAssert is there to be short and easy way to write and to check any assumptions you have made in your code. It is not (in my opinion) an alternative to exceptions, just a shortcut. If an assertion fails then something has gone terribly wrong … Read more
You can change the maximum method/function length warning behavior in NetBeans options (it’s under Tools->Options->Editor, in the Hints tab, under “Too Many Lines” section in the checkboxes list). There you can set the maximum number of lines, how you would like to be warned, etc. I believe that the rule was introduced by NetBeans developers … Read more
Everyone else uses 4 spaces. That is the only reason to use 4 spaces that I’ve come across and accepted. In my heart, I still want to use tabs (1 indent character per indent, makes sense, no? Separate indent from other whitespace. I don’t care that tabs can be displayed as different widths, that makes … Read more
This can be appropriate when the pointer itself can be regarded as a “black box”, that is, a piece of data whose internal representation should be irrelevant to the code. Essentially, if your code will never dereference the pointer, and you just pass it around API functions (sometimes by reference), then not only does the … Read more
In C++11 where std::array is available, the answer is “yes, arrays should be avoided”. Prior to C++11, you may need to use C arrays to allocate arrays in the automatic storage (i.e. on the stack).
The best practice in my point of view is to go sequentially and declare your methods without keeping private in point of view. At the end, you can make make any method private by just adding: private :xmethod Example: class Example def xmethod end def ymethod end def zmethod end private :xmethod, :zmethod end Does … Read more
The first is more idiomatic. In particular, it indicates (in a 0-based sense) the number of iterations. When using something 1-based (e.g. JDBC, IIRC) I might be tempted to use <=. So: for (int i=0; i < count; i++) // For 0-based APIs for (int i=1; i <= count; i++) // For 1-based APIs I … Read more
Use the standard dictated by the surrounding software. For example, in my current project the YAML file contains default values for Python attributes. Since the names used in YAML appear in the associated Python API, it is clear that on this particular project, the YAML names should obey the Python lower_case_with_underscores naming convention per PEP-8. … Read more
In the long run I think you’ll appreciate having most of your imports at the top of the file, that way you can tell at a glance how complicated your module is by what it needs to import. If I’m adding new code to an existing file I’ll usually do the import where it’s needed … Read more
I usually say ‘such that’ when reading that operator. In your example, p => p.Age > 16 reads as “P, such that p.Age is greater than 16.” In fact, I asked this very question on the official linq pre-release forums, and Anders Hejlsberg responded by saying I usually read the => operator as “becomes” or … Read more
