Why we dropped Docker for Python environments

TL;DR Docker is a great tool for managing software environments, but we found that it’s just too slow, especially for exploratory data workflows where users change their Python environments frequently.

We find that clusters depending on docker images often take 5+ minutes to launch. Ouch. In Coiled you can use a new system for creating software environments on the fly using only mamba instead. We’re seeing start times 3x faster, or about 1–2 minutes.

This article goes into the challenges we (Coiled) faced, the solution we chose, and the performance impacts of that choice.

Large-Scale Datamining & Built a Reddit Bot for r/boardgames to reply with BGG Links

Disclaimer: I am in no way affiliated with BoardGameGeek aside from being a user of the site.

I was inspired by u/MTGCardFetcher who replies on the Magic: The Gathering subreddits with links to the card images and text when called with a card name in double brackets. I've often found myself replying to a thread on r/boardgames with the name of a game (or, more appropriately, reading others' suggestions) without a link, making it slightly more annoying to look the game up.

As a result, I built two Python scripts - one to discover the game pages on BoardGameGeek.com and extract the game name and year and another to serve as the reddit bot.

I'm used to crawling sites using Screaming Frog and had fully intended to use it to pull the game names and other details out, but it turns out BoardGameGeek uses a degree of client-side rendering, making a non-rendered request fall short of extracting data. My solution was to use Selenium to hit the pages, wait for //h1/a to be discoverable, then extract the text. At the time of writing this, there are just over 174,000 board game and board game expansion pages on BoardGameGeek. It took several full days

(Help Needed) Trying to make DateField Input set to date

Hi all,

I've been trying to have a datepicker for my DateField but it rendered as text instead of date. I understand from the Django documentation that by default the input is text, here is my code trying to change the input to date. (I am using crispy forms)

PokéSearch: FastAPI + React (Open Source)

# Context

Hey everyone, I'm new to the Pokémon games and currently I'm playing the latest one. When playing online, you have to to pick your team based on your enemy's team. However, it's difficult for me because I'm not familiar with most of the Pokémon types and you can't see their names to look them up.

# PokéSearch

That's why I created PokéSearch, a web app that allows you to search for a Pokémon based on characteristics. For example, if you search for the word "green" all green Pokémon will appear (other search examples: robot, red, legendary, eevee, water, fire).

Live web app:

https://pokesearch.help/

# Technical Details

The API is made with FastAPI and the frontend with React + Tailwind.

The API is in charge of providing a list of all the Pokémon given a region, along with their respective types, resistances, and weaknesses. The frontend then filters the list based on user input.

Federated-Recommendation-Neural-Collaborative-Filtering

Neural Collaborative Filtering (NCF) is a paper published in 2017. It is a common methodology for creating a recommendation system. However, recommendation data might not want to be shared beyond your own device. Therefore, last year, I looked into applying this ML algorithm in a Federated Learning setting, where your data stays on your own devices.

My first Django project

Hello everyone, I'm 17 years old and have been learning Python for 6 months, and I've been studying Django for the last 2 months. During this time, I completed my first Django pet project. I'm interested in your opinion about this project. How does it compare to the average statistical project, and what improvements or additions could be made, or vice versa, what should be removed? Overall, I would appreciate hearing your thoughts on it.

Help on selecting the sum of a specific value

category.current = db.session.query(db.func.sum(`db.select`(Expense.amount).filter_by(category_id=category_id).order_by(Expense.amount))).scalar()

so this is a line of code form a program I'm working on to handle suers purchases. This code mostly works and adds the values to the proper database in the end as this is to compile all the purchases and sum them together based on each category. However for some reason when this line of code is executed it only adds one number to the system instead of summing them all, any help would be much appreciated. Thank you

Python quiz game to Flask web app

Hello!

So, I created a python quiz game which is currently running all text based with questions asked, alternatives (1-4) presented and a user input (1-4) checking if the answers are correct.

Basically the questions are presented (one at a time) like this:

Who had a hit with 'St. Elmo's Fire (Man In Motion)' in 1985?

1 : The S.O.S. Band
2 : John Parr
3 : Neil Diamond
4 : New Kids On The Block

Please select 1, 2, 3 or 4:

If the answer is correct the user gains a point. If the user gets a certain amount of points new and harder questions will be available.

I would love to create a Flask web app running this concept but with clickable buttons. Something like this:

I guess this would require me to use something like Javascript or similar. That is my guess as I am new to this...

So I guess my question is: Would learning javascript be the way to go? Or are there other (better?) options available?

Is there any API or anything else that can help extract flight information from a ticket?

So far I tried using OCR.Space to feed the image, extract data from the ticket and try to work with it but it’s not so accurate. I was wondering if there are other way of doing so perhaps an API where you enter flight ticket number and gets you all the information or maybe another way?

Bing AI made up a package that doesn't, but maybe should, exists and even gave examples of how to use it. Read/Write session splitter for sqlalchemy.

I notched today that my skype has a Bing chatbot built into it now, so I thought I'd see what it had to say about what I'm working on.

https://preview.redd.it/jyepb53opqta1.png?width=1030&format=png&auto=webp&v=enabled&s=9c9a2d68dbbd41a7862e21138f275f07128c6348

As far as I could find, there is no package named sqlalchemy-splitter, or even something that works similar to the way they describe it.

https://preview.redd.it/jzbz3ii7qqta1.png?width=1030&format=png&auto=webp&v=enabled&s=54c2b88f97a79516885086864b055ed92a7f893d

It seems pretty sure of itself. After thinking about it though It seems like a package like this would probably have to do a lot of extra work in order to manage both sessions and move objects between them. Maybe its not as difficult as I'm thinking though?

Either way, when I called it out it immediately back peddled.
