[D] Machine Learning - WAYR (What Are You Reading) - Week 44

This is a place to share machine learning research papers, journals, and articles that you're reading this week. If it relates to what you're researching, by all means elaborate and give us your insight, otherwise it could just be an interesting paper you've read.

Please try to provide some insight from your understanding and please don't post things which are present in wiki.

Preferably you should link the arxiv page (not the PDF, you can easily access the PDF from the summary page but not the other way around) or any other pertinent links.

Most upvoted papers two weeks ago:

/u/marcossilva_604: https://arxiv.org/abs/1802.06006.

/u/hohomomo1212: Learning to Play with Intrinsically-Motivated Self-Aware Agents (https://arxiv.org/abs/1802.07442). It is a paper on a form of reinforcement learning without extrinsic rewards. Think of a robot wandering around in the world without being told what to do but instead figuring out what to do by itself using a model of its own abilities. That's why they call it self-aware. Pretty cool :)

Besides that, there are no rules, have fun.

What are some fun things to do with Python?

I became fluent in Python a few years ago but never used it for anything besides assigned coursework or job related tasks. I’ve been looking to apply my skills in a way that would inspire me to excel while being enjoyable and have been having a fairly hard time with it.

So what are the most fun things you’ve used Python for that can be turned into a long term hobby?

Never put DEBUG = True in any django server that is accessible from outside your LAN

While this is quiet obvious and must have already read it in django docs, many people (me included) still do it sometimes.

**Why?**

Mainly because ~~most recommended django configurations,~~ Django doesn't serve static/media files if `Debug = False`. So you might be tempted to temporarily set `Debug = True` while your client is reviewing the website and making the final changes before deployment.

**Why `Debug = True` is Evil?**

When any exception happen, django expose all your settings, environment variables to the world.
Remember that `SECRET_KEY` settings that django tells you never reveal? It's there for anyone across the globe to view freely.
Database password? Yep, it's there also.
Email credentials? API for external services? All there.

I know some of you would call me stupid for setting `Debug = True` on a test site that is accessible online and I would agree.
I'm writing this so that no one else would be doing that stupid mistake

My first automated web scraping for Lego sets.

Using Python and selenium, I made a crude script which web scraps and extracts the Title, item number, Numbers of Pieces and Product Details for different Lego sets.

store app config in sqlite

I have an app that will be polling info from an api.

I want to be able to store the credentials and other config components in sqlite.

Is there already a framework for this ?

What is the WordPress framework of the Django world? I want to throw up a site that's blog oriented and I'm contemplating brushing up on PHP 7 or just scrapping that and learning Python to throw up some kind of Django solution. Thanks for the direction.

How do you implement reset password functionality with Django Rest Framework?

Hi devs,

I'm having a bit of trouble to understand this, without DRF I did it successfully by using Django's default auth views and creating my templates but what about DRF?

Should I create a model that stores a token on the database and them verify if the token is valid for the user? If so, how to best generate this token, what to keep in mind to make the implementation as safe as possible?

Can I use Django's own mechanism which, by what I read, takes into account the last login, the current password (?), and adds some salt? This seems to be a very well thought implementation but can I borrow that mechanism into my RESTful views?

How are you (more experienced) guys doing this?

PS: I'm using only Simple JWT, not using other auth libraries like allauth or social login, don't know if this is relevant to the case.

Heroku Django application error!

Hey guys i have created my first django website! and i want to upload it through Heroku, So i followed everything they said to me and i am still getting application error wheni am trying to do
heruko open
I get an application error and as i am beginner to heruko i am frustrated to get errors! I found that i am getting error here while i do
git push heruko master
I get all things ready but a small error after deploying is done and the error is:

I also think the error is with the Procfile because i don't know what name we should type in the wsgi.py as given below:
web: guincorn whatnameshouldiwrite.wsgi

I found that we should write our app name but i have two apps in my project and i have different name for my heroku website and a different name for my project on my PC so which name should i write there?

What are some simple django-based blog projects which developers starting in webdev can use?

I am looking to start a django-based blog and would like to see if people have any recommendations for "ready-made" projects. Something like this as an example: https://github.com/miguelgfierro/sciblog.

My objective is to get the blog up and running as soon as possible and customize it with time. My theoretical webdev knowledge is good although I have zero practical experience and I want to take this opportunity to learn.

What are some simple django-based blog projects which developers new to webdev can start with?

Anyone use Okta? Is it as easy as Flask-Login?

I'm just starting out with Flask, have found using Flask-Login really easy and pretty cool. But I'm worried about data protection, and thought using Okta might reduce liability. Anyone doing the same? Can it integrate with Flask-Login? The workflow for Okta looks pretty heavy - any opinions?
