Faster than calling abs()

instead of
a = abs(a)
I tried
a = a + (a<0) * (-a-a)

measured it with 10 million calls and it runs in 58% of the time,
see anything wrong with this?

saw some other post where people suggest setting _abs = abs before the loop and use _abs() inside it to make it faster

and still my method runs in 68% of the time it takes the _abs() method.

Open Source Django Projects for Study

Hello everyone,

I'm looking for open source projects made using Django, preferably Django REST Framework, that fix real business problems, and whose code I can analyze, get ideas and learn from.

So far I've got GitHub repositories of Saleor, Django CMS, Wagtail, and a few more, but I would like to see a solution like an inventory management system of a company, HR system, an API that manages data of a game server, something like that, but I guess anything you find interesting or worth seeing could help.

I know that companies wouldn't release their code like that, but there are probably open-source solutions released to the public somewhere on the internet.

So, are there any repositories you could recommend for analyzing, and learning Django a little more in-depth?

Thanks!

Web app with JavaScript

Hi!

I need some advice. For my portfolio I want to build a web app for my national sports team. A bit like a news website but with some more features. I know Flask already and want to work on my JS skills also. I get confused when reading to use Flask for the backend and JS for frontend. I built Flask only apps without any JS. What will be different when using JS too? Are redirects, form submissions, validations, etc.. still handled by Flask? Do people still use jinja and what would be things I've done normally with Flask and now with JS?

Thank you!

Is it Bad to have gunicorn --reload option enabled in Production?

Is there any downside to having the --reload option enabled for Gunicorn in production? For example, does it require additional memory or CPU or anything? I imagine it must have to poll for changes to files.

I created some code to test the search functionality for elasticsearch to have a better understanding of the code. I wrote the code quickly so it is crappy code but it mostly runs . The problem is when I run the code and click search nothing appears. I assume it is the html causing the problems.

Can someone help fix the errors?

&#x200B;

I am following this tutorial https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xvi-full-text-search

&#x200B;

&#x200B;

&#x200B;

To save time here is my environment.yaml code

name: py
channels:
- defaults
dependencies:
- python
- flask-wtf
- flask-sqlalchemy
- flask-login
- elasticsearch
- flask-migrate
- bcrypt
prefix: C:\Users\user\Anaconda3\envs\py

Also of important note I just want to state that I manually added the Post columns by using the code below in the command line.

&#x200B;

from app import db, app
from app import User, Posts
with app.appcontext():
post = Post(title='The Second Posts', body='Here is the body text')

&#x200B;

I also tested to see if the column was added and it seems to be by using the example below.

&#x200B;

from app import Post
post = Post.query.filterby(body='Here is the body text').first( )
print(post)
print(post.title)

stacked quantiles

This is going to be niche, but just in case. I use this code a lot, so I uploaded it. For those of us who work with pixels and such where you might have 10k of the same value.

ShayHill/stacked\_quantile: Treat weighted values as multiple values. (github.com)

​ 'Stacked' quantile functions. Close to weighted quantile functions.

These functions are used to calculate quantiles of a set of values, where each value has a weight. The typical process for calculating a weighted quantile is to create a CDF from the weights, then interpolate the values to find the quantile.

These functions, however, treat weighted values (given integer weights) exactly as multiple values.

So, values (1, 2, 3) with weights (4, 5, 6) will be treated as

(1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3) If the quantile falls exactly between two values, the non-weighted average of the two values is returned. This is consistent with the "weights as occurrences" interpretation. Strips all zero-weight values, so these will never be included in such averages.

If using non-integer weights, the results will be as if some scalar were applied to make all weights into integers.

This "weights as occurrences" interpretation has
