Composer: how can I install another dependency without updating old ones?
...nstall the package, and add it to composer.lock.
You can also specify an em>x m>plicit version constraint by running:
composer require new/package ~2.5
–OR–
Using the update command, add the new package manually to composer.json, then run:
composer update new/package

How do I pass em>x m>tra arguments to a Python decorator?
...ctual_decorator
The outer function will be given any arguments you pass em>x m>plicitly, and should return the inner function. The inner function will be passed the function to decorate, and return the modified function.
Usually you want the decorator to change the function behavior by wrapping it in ...
How to only find files in a given directory, and ignore subdirectories using bash
... just want to limit the find to the first level you can do:
find /dev -mam>x m>depth 1 -name 'abc-*'

How to pass a class type as a function parameter
... allow any class. In this case the right type would be T.Type, because it em>x m>presses the link between the returningClass parameter and the parameter of the closure.
In fact, using it instead of AnyClass allows the compiler to correctly infer the types in the method call:

'Median of 3' is NOT first last middle. Choose three random indem>x m>es, and take the middle value of this. The whole point is to make sure that your choice of pivots is not deterministic - if it is, worst case data can be quite easily generated.
