Python Linked List
...ail. This is very useful for dynamic algorithms that require saved values from previous iterations where sharing list tails can reduce memory complexity from quadratic to linear and eliminate time overhead due to copying.

How to resolve git's “not something we can merge” error
...hown in How does "not something we can merge" arise?, this error can arise from a typo in the branch name because you are trying to pull a branch that doesn't exist.
If that is not the problem (as in my case), it is likely that you don't have a local copy of the branch that you want to merge. Git r...
Why does the Scala compiler disallow overloaded methods with default arguments?
...
I'd like to cite Lukas Rytz (from here):
The reason is that we wanted a deterministic naming-scheme for the
generated methods which return default arguments. If you write
def f(a: Int = 1)
the compiler generates
def f$default$1 = 1

How do I commit case-sensitive only filename changes in Git?
...set this setting to false:
git config core.ignorecase false
Documentation
From the git config documentation:
core.ignorecase
If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds...
Why does += behave unexpectedly on lists?
...
At first it feels weird to think that a += b is different from a = a + b for two lists a and b. But it makes sense; extend would more often be the intended thing to do with lists rather than create a new copy of the entire list which will have higher time complexity. If developers n...
Best way to find the intersection of multiple sets?
...
From Python version 2.6 on you can use multiple arguments to set.intersection(), like
u = set.intersection(s1, s2, s3)
If the sets are in a list, this translates to:
u = set.intersection(*setlist)
where *a_list is list ...

How can I debug javascript on Android?

Note from the Chrome for Android remote debugging link: "You should be signed in to Chrome with one of your Google accounts. Remote debugging does not work in Incognito Mode or Guest Mode." Wow, why?

Convert hex string to int in Python
...g to an int, pass the string to int along with the base you are converting from.
Both strings will suffice for conversion in this way:
>>> string_1 = "0xffff"
>>> string_2 = "ffff"
>>> int(string_1, 16)
65535
>>> int(string_2, 16)
65535

How do I execute a bash script in Terminal?
...
@kot "It happens to work for me" is very far from "this is a correct answer". It can work if sh is a symlink to bash, or if the script does not use any Bash-specific construct. In the former case, using bash instead of sh is the only correct, portable solution; in the l...
