... On the other hand, our variables are package variables, and thus automatically: global variables definitely not private not necessarily new can be accessed outside the package (or lexical scope) with the qualified namespace, as $package_name::variable. Declaring a variable with our allows you...

...emoves an element from the page layout entirely, as if it wasn’t there. All other values for display cause the element to be a part of the page, so in a sense they’re all opposite to display:none. But there isn’t one value that’s the direct converse of display:none - just like there's no o...

...of a 1D array is still a 1D array! (If you're used to matlab, it fundamentally doesn't have a concept of a 1D array. Matlab's "1D" arrays are 2D.) If you want to turn your 1D vector into a 2D array and then transpose it, just slice it with np.newaxis (or None, they're the same, newaxis is just mor...

...his is also a problem for square brackets and braces, even though those usually occur as balanced pairs.) You can enclose the macro argument in parentheses: FOO((std::map<int, int>), map_var); The problem is then that the parameter remains parenthesized inside the macro expansion, which pr...

I tend to declare as static all the methods in a class when that class doesn't require to keep track of internal states. For example, if I need to transform A into B and don't rely on some internal state C that may vary, I create a static transform. If there is an internal state C that I want to be ...

...t to to do it beforehand, if you just add the line to the .gitignore file, all previously committed .pyc files will still be tracked, so you'll need to remove them from the repository. If you are on a Linux system (or "parents&sons" like a MacOSX), you can quickly do it with just this one line ...

... that every reference type gets this extra state in its space that is typically undesired. A string variable could be any sequence of characters, or it could be this crazy extra null value that doesn't map into my problem domain. A Triangle object has three Points, which themselves have X and Y va...
