and does writing such code guarantee that I understand eve...
I had a homework to create a simple hex editor that reads binary files as well as write integers to it. However I enhanced it a bit. Homework is already given but that doesn´t mean this code will remain without a review :)

On Code Review we often encounter questions with the same kind of problem over and over again.
Some of us are using the auto comments script which allows you to maintain a list of comments to post.
What are some useful tin-can comments that can be good to have in your list of comments?

This always bothered me. I've read the Stack Overflow help center. I've read the Code Review help center. Nowhere in either...

I'm trying to generate prediction bands for an exponential fit to some 2-dimensional data (available here).
The data (blue points), best fit found by scipy.optimize.curve_fit (red curve), and lower & upper 95% prediction bands (green curves) can be seen in the image below.
(the MWE is at the ...
I have to write a python function that takes a string that contains raw unicode strings (e.g. "u'hello' there") and transform it into a string that strips the u'' identifiers from it. For example:
strip_inline_unicode("u'hello' there") # -> 'hello there'
Without getting into too much detail a...
The criteria for migrating a question are:
The question is off-topic on the current site.
The question is high-quality.
The question is on-topic for the target site.

I'm trying to optimize a nested for loops that compares an element in the array with the rest of the element in the array.
There's two part, the first part is for example, an Array has 3 elements, and each element is a dictionary:
[{"someKey_1":"a"}, {"someKey_1":"b"}, {"somekey_1":"a"}]

Below is my solution for this 'Team Split' problem.
In summary, the problem is to find relative strength of 2 teams by finding the difference between their total strength (individual strengths can be found using a quadratic expression of form ax2+bx+c).
The solution in Java manages to solve the...
I had some time to kill today, and I found the Karate Chop Kata.
Specification:
Write a binary chop method that takes an integer search target and a sorted array of integers. It should return the
integer index of the target in the array, or -1 if the target is not
in the array.
