I thought this question made a good excuse for some basic OOP code, so I whipped up a little bit of code to demonstrate it in VBA; the idea is to have tutorial-grade code, to show how interfaces and default instances can be used to implement immutable types and factory methods to simulate constru...

I recently wrote the livejson module as a way to make working with JSON in Python easier. The idea of the module is that you initialize a livejson.File, and then you can interact with your JSON file with the same interface as a Python dict, except your changes are reflected in the file in realtim...
I've written some code to scan large files and search for long strings that you can write without repeating a letter. I'm self-taught in python and I'm wondering what I've missed.

The problem is that findall only searches the immediate descendants of an element if it is given a tag name. You need to give it an XPath expression that will find track anywhere in the tree beneath it. So the following should work, for example:
api_results = ElementTree.parse(response).findal...

I have two matrices a and b that have, on each line, some values (null or not) and then a bunch of zeros at the end.
I want to construct a matrix c that for each line has the corresponding line of a from the first element till to the last not-null element, concatenated with the corresponding lin...

I am working on a user login using Flask and the following extensions: Flask-Login, Flask-WTF, WTForms and Flask-SocketIO
Client-Side
Rendering of Forms and pre-filling with data is done with Flask-WTF / WTForms just like this:

Currently all this does is retrieve data from specific columns, the final result will be that I will check the data to make sure that it passes the test cases, but I want to look at this foreach right now and see if I can't make it a little simpler.
A lot of what I have coded I have come back ...

The application I'm working on needs to occasionally take pictures, and then send them to either an ftp server or a network drive (user configurable). To try to abstract away the differences between a ftp server and a network drive I made this class.
The idea is, the code that takes a picture wi...

This is a code that gets a list of polygon vertices, non ordered, and finds the order in which they should be arranged in order to create the polygon with the largest area.
There are two key elements in the approach:
Testing the area of the polygon is done by monte-carlo calculation. Random po...0
I have switch statement that is switching on an enum to build a ContextMenu depending on what the selected enum value is. While the various enum values require different operations in their cases of the switch, some of them require some of the same operations.

I asked a question over at StackOverflow. Was told it might be more appropriate here. This is a toy version of the code I really want to write:

char val;
struct node_s *next;
} node;
int n;
char obtain_next_char(){

The program can be used to hide an image within another image and later extract the hidden image. This is done by concealing the secret image within the lowest bits of the apparent image. Example of a cat hidden within a tree.
I split it into 2 programs to make commandline args parsing easier, C...

Hi was told this was the best place to post working code to get suggestions for improvement, I hope this is OK.

I created this as a template for our email marketing team to use when creating emails. For fluid/responsive behavior, I am using max-width and conditionals for clients that do not support it (mso).
If anyone could give some suggestions for improvement, that would be AWESOME!

Tritium (/ˈtrɪtiəm/ or /ˈtrɪʃiəm/; symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (by far the most abundant hydrogen isotope) contains one proton and no neutrons. Naturally occurring tritium is extremely rare on Earth, where trace amounts are formed by the interaction of the atmosphere with cosmic rays. The name of this isotope is formed from the Greek word τρίτος (trítos) meaning "third".
== Decay ==
While tritium has several different e...

If you are unfamiliar with the logic puzzle game Takuzu, I learned how to play it and was inspired to make the project from this challenge posted on reddit. The short version of the game is it's a logic puzzle that uses 0s and 1s on an nxn grid that does not allow three repeating numbers in a row...

I have 7 variables controlling 7 widgets showing or hiding from the frontend. I want to put them together and control all of them using one function. Here is what I have. However, I feel like even though this way works, the code is really ugly and should have space for improvements. Thanks in adv...
