So, I have a table named items_list which have a column called 'Item N...

My goal is to make a very simple library with the authentications basics: create a user and save its hashed password, change its password, have a method to check if the password is correct for login.
The usage I thought (you find everything in my Github repository), is this:

This code finds which "secure file erase" command exists on the system. It used to simply test for "shred" and pick "rm" as a default. Now it is a bit more complex since I've ported the code to operating systems with "srm" and "rm -P". Is this still cleanly written? How can I improve it?

I had a need to build a standardized layout for content on many of the pages of my website based on data returned from my web service but the project I'm doing this on is already bloated with stuff from previous developers and since I don't know what I can take out without destroying functionalit...
I've written a little program that I need for fixing two problems in my spherical panorama images.
It does two things:
If the image does overlap horizontally, it cuts away the overlapping pixels from the right side.
It fills up the image vertically with black, so that it has a ratio of 2 to 1.

The ubiquitous dplyr package has the function mutate_at (and many other *_at()'s), which allows us to perform a similar operation on multiple columns. Using purrr-style formulas, the relevant column is indicated by .:
df %>% mutate_at(vars(colA, colB, colC), ~ 2 * .)
This would double the values...
I am trying to create a list based on some data, but the code I am using is very slow when I run it on large data. So I suspect I am not using all of the Python power for this task. Is there a more efficient and faster way of doing this in Python?
Here an explanantion of the code:
