A few days ago I started writing my own compiler-like program which has the goal to compile plain text into executable python code. After I let my first version review here, I made huge changes to the overall code and added the possibility of adding rectangles. I try to add all the suggested impr...
I build a cart for an ecommerce website, and I want to know if I did well.
I want to record the changes in the DB and display the information from the DB to the customer. To be sure that what he sees is the good information. I use an ajax request and JSON to do so.
Please give me your comments....
I combine two query sets (available_tickets_by_event and sold_tickets_by_event. My end goal is to combine it in ticket_stats_by_event. I wonder if there is a more efficient way to combine these`?

I was wondering what the general wisdom was on comment-to-code ratio. What constitutes too much / too little? Of course that depends on the code itself, but I'm just trying to get a ballpark figure.
Consider this python script for creating github-style identicons:

I currently saw a company using this kind of software design which i have never seen before:
The system is based on each class in the system is inheriting a class called Component which looks something like this:

Please, help me to understand the complexity of this code. I have tried to calculate and did not find it to be close to \$\mathcal{O}(mn)\$ but rather closer to \$\mathcal{O}(m+n)\$. I have compared it to KMP (Knuth-Morris-Pratt string matching) and realized that in the case of str='cccccc' and p...
I have created a date component (working GIF at the bottom).
There isn't a problem with the working of the code but rather the code I wrote seems messy and something hard for any other person to comprehend.
Note: Please look at the GIF below. Also, Ignore the styling
This is what I am doing:...
I was refactoring an ugly piece of code, and I'm unsure if there is a better way of doing this, and whether I'm overdoing it with streams.
Basically I get a bunch of columns, which should be grouped by the name of the sheet they belong to, so that I can return a map of sheet names to a set of c...
I was working on a client for a remote api and realized that i needed to throttle requests to < 4/second. I wrote a simple typescript class to do it and wanted to solicit code review- it basically should accept a () => Promise and return a Promise that resolves once executed by the queue.

Story-based adventure program I coded by myself (forgive the length). It took a long time but it was fun. This includes loading times, changes in relationships, relationship levels, storyline and possible outcomes, user input with xbox-style options, function calling and more.

I am making a subclass of a well-established python class: pendulum.Period, which overrides both __new__ and __init__ (it does this because it is subclassing the python builtin class timedelta, which uses __new__).
