Git add and commit in one command
...sy way to add all files new or modified. Also, the catch-all qualification applies. The above commands will not delete files deleted without the git rm command.
git add app
git commit -m "message"
is an easy way to add all files to the index from a single dir, in this case the app dir.

Immutable vs Mutable types
... pass by value in C. A counterexample to your analogy is if you do def f(my_list): my_list = [1, 2, 3]. With pass-by-reference in C, the value of the argument could change by calling that function. In Python, that function doesn't do anything. def f(my_list): my_list[:] = [1, 2, 3] would do somethin...
Check if a value is within a range of numbers
...could use the inRange() function:
https://lodash.com/docs/4.17.15#inRange
_.inRange(3, 2, 4);
// => true
_.inRange(4, 8);
// => true
_.inRange(4, 2);
// => false
_.inRange(2, 2);
// => false
_.inRange(1.2, 2);
// => true
_.inRange(5.2, 4);
// => false
_.inRange(-3, -2, -6);

C/C++ with GCC: Statically add resource files to executable/library
... an iterator.
If you're using this with automake don't forget to set BUILT_SOURCES appropriately.
The nice thing about doing it this way is:
You get text out, so it can be in version control and patches sensibly
It is portable and well defined on every platform

Open a URL in a new tab (and not a new window)
... is a trick,
function openInNewTab(url) {
var win = window.open(url, '_blank');
win.focus();
}
In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event li...
How exactly does a generator comprehension work?
...s, and yields each item out of the expression, one by one.
>>> my_list = [1, 3, 5, 9, 2, 6]
>>> filtered_list = [item for item in my_list if item > 3]
>>> print(filtered_list)
[5, 9, 6]
>>> len(filtered_list)
3
>>> # compare to generator expression

What is the most efficient way to loop through dataframes with pandas? [duplicate]
...if close is a 1-d array, and you want the day-over-day percent change,
pct_change = close[1:]/close[:-1]
This computes the entire array of percent changes as one statement, instead of
pct_change = []
for row in close:
pct_change.append(...)
So try to avoid the Python loop for i, row in en...
What do the python file extensions, .pyc .pyd .pyo stand for?
...could in some rare cases result in malfunctioning programs. Currently only __doc__ strings are removed from the bytecode, resulting in more compact ‘.pyo’ files. Since some programs may rely on having these available, you should only use this option if you know what you're doing.

Difference between MEAN.js and MEAN.io
...ilosophy and openness of MeanJS and more the traction and modules/packages approach of MeanIO. Both are nice, and you'll end probably modifying them, so you can't really go wrong picking one or the other. Just take them as starting point and as a learning exercise.
