...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...

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 ...

Occasionally maven complains that a particular dependency, which is built and packaged locally, cannot be found in the local repository while building another project that has it as a dependency. We get an error like: ...

...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...

...ur own queue, just use the inherited one. If you do as you do, you can actually do nothing else with the queue values, all other functions but your new Enqueue will still call the original queue. In other words, although this answer is marked as accepted, it's completely and utterly broken. ...

...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...

...sizeof(struct { int: -!!(e); })) (e): Compute expression e. !!(e): Logically negate twice: 0 if e == 0; otherwise 1. -!!(e): Numerically negate the expression from step 2: 0 if it was 0; otherwise -1. struct{int: -!!(0);} --> struct{int: 0;}: If it was zero, then we declare a struct with an an...

...ff using decimal numbers is A LOT more intuitive (we have 10 fingers after all - at least most of us), so declaring a number of something using hexadecimals seems like an unnecessary code obfuscation. – Andrew Cyrul Apr 13 '17 at 9:27 ...

... You need to either convert each table individually: ALTER TABLE mytable CONVERT TO CHARACTER SET utf8mb4 (this will convert the columns just as well), or export the database with latin1 and import it back with utf8mb4. ...
