Storing millions and billions of URLs?

Hello Everyone!

Currently, using ElasticSearch for storing the meta data and other raw data information but it is a very small scale around 500,000 domains.

I have been tasked to scale it to 20-40 million domains and storing their internal/external links while building a page rank/domain authority score for each domain which we are adding to our database.

What do you guys suggest/recommend for storing this data at a very large scale as web page internal links/external links will be stored which will lead it over 100M-1B links database?

Any kind of feedback/suggestion would be appreciated.

Thanks.

How to make the transition from "python scripter" to "python software developer"?

Hello there. I recently got hired as software developer for some of the skills that I have, but none of those is actually being a good software developer. I'm writing Python code 5+ years now, but never really exposed my code to being reviewed, tested or criticized. The people I work with have not only more experience but their background also entails software development. I try to learn as much as possible from them when I read their Python code, but I want to get on a higher level in terms of coding quality as soon as possible.

Can you give me any tips how I can get there? Whether it is good article, book or a DOs and DONTs cheat-sheet, I don't know, but whatever it is I would appreciate some tips!

Does anyone know a django app to handle Feature Requests?

I'm looking for something similar to [gog's Community Wishlist](https://www.gog.com/wishlist): users can submit requests for new features and the like, and other users can vote in which features they want the most.

Comments in each request would be appreciated, but aren't necessary.

Numpy FFT lots slower than Octave FFT?

After trying Octave and missing Python's features, I've been back to Python / Numpy. But now it's looking like Numpy is significantly slower? Here's the test. Python, about 10 seconds:

import numpy
numpy.fft.fft(numpy.ones(31257584))

Octave, about one second:

sum(fft(ones(1, 31257584)))

I'd rather use Python, but don't have time to wait for it.

flask restfull handle incorrect urls

I am using the Flask_restful package and I have a question. I have some paths like: /api/users/<int:id>/recepies. Everything works fine until you request this url without the id, like this: /api/users//recepies or /api/users/recepies, then it throws an error. Is there a way to catch this kind of errors?

migrating from sqlserver to postgres, issue with sqlserver_ado.fields.BigAutoField

I am trying to change our django from using M/S SQL server to postgres. One of the model fields is defined in the initial migration as sqlserver_ado.fields.BigAutoField(serialize=False, primary_key=True). After changing the database engine to postgres, the field is missing in the postgres database. If I try to migrate it to something like models.BigIntegerField(serialize=False, primary_key=True), I get the error "ValueError: Cannot alter field verosgui.MpWatchlistchange.chan_coun into verosgui.MpWatchlistchange.chan_coun - they do not properly define db_type (are you using PostGIS 1.5 or badly-written custom fields?)". Does anyone know how to migrate this field?

How to run a task after flask server starts?

Hey guys, I'm trying to run my flask site in a pyqt5 GUI interface however after app.run(), all functions afterward are ignored until I close the server. This results in me getting a 404 from the PyQT interface. Anyone know how to run the flask server and allow a function to run after it? If it is possible, it would actually be better if I could run them at the same time. Thanks guys



**EDIT**: solved this actually
did the following

def pyqt_function():
#thing to be done by pyqt
t = threading.Thread(target=pyqt_function)
t.daemon = True
t.start()
app.run()

Would /r/django be interested in a livestream/VOD series building real-world Django apps from the ground up?

I've been thinking of starting up a streaming/VOD series that builds real-world applications from start to finish. My plan for the first stream would be building an RSS reader from scratch and going over the various concepts along the way. I'm a little tired of seeing all of the "Learn Web Development for Absolute Beginners" series that end after part 2 popping up all over the place. I'd love to create some content that builds an app with real value and be able to answer questions from people as I go along.

I want to gauge interest from the different communities to see what they think and figured I'd start here since I'd be using Django. What are your thoughts on the idea? Would you be interested in watching/participating?

Thanks for any feedback.

EDIT: alone -> along

Configuring position of docstrings?

When I check the docstring of a Python function, it opens at the bottom of the browser window. However, since my screen has the standard shape of being wider than high, this means that when running the Jupyter notebook there's a lot of wasted space at the sides. It would therefore be terrific to have the docstring open at the side of the notebook cells, rather than underneath them. I could then have a docstring open without losing any notebook screen real-estate.

Can this be done?

Modern Django tooling and testing

Hi hackers,
I'm relatively new to Django but not to web development. What are some essential libraries and tools you use for modern Django development? What are some "must haves" in your Pipfile? And how are most folks testing these days?

Currently, I use:

[packages]
django = "*"
"psycopg2" = "*"
gunicorn = "*"
django-heroku = "*"
dj-database-url = "*"
whitenoise = "*"
django-dotenv = "*"

[dev-packages]
green = "*"

I am especially interested in testing, as the Python and/or Django test frameworks, aren't quite as powerful, out of the box, as what I'm used to from other ecosystems.

Bonus points for a "modern" guide to working with Django.

Conditional Counting

Let's say we have the following simplistic models:


class Category(models.Model):
name = models.CharField(max_length=264)

def __str__(self):
return self.name

class Meta:
verbose_name_plural = "categories"

class Status(models.Model):
name = models.CharField(max_length=264)

def __str__(self):
return self.name

class Meta:
verbose_name_plural = "status"

class Bet(models.Model):
title = models.CharField(max_length=264)
description = models.CharField(max_length=264)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
price = models.DecimalField(max_digits=10)
status = models.ForeignKey(Status, on_delete=models.CASCADE)


Status choices would be: Sold, Not Sold, Reserved, Withdrawn.

My aim is for each category to get the total amount of products and how many were Sold or Reserved.

This would get the total amount of products per category:

qs = Product.objects.all().values("category__name").annotate(total_products=Count("id"))

Including how many were Sold or Reserved:

qs = Product.objects.all().values("category__name").annotate(total_products=Count("id"), total_available=Count(Case(When(status__name__in=["Sold", "Reserved"], then=True), default=False, output_field=BooleanField())))

I am not sure if it's the correct way, total_available appears to return all the products per category.
