Does anybody know what is going on with micropython?
This topic might be a bit off-topic here, but the micropython-themed subs are dead. Has the project failed or something? Has the hardware side been abandoned by the official micropython team? The pyboard is permanently "out of stock".
Is there a new reference board? Something I can buy to play around with no real goal in mind?

Several Django projects, one Web Server
Which is the best approach to deploy different Django projects under the same Web Server?
I got a Ubuntu Server, running Nginx, and I got a Django project (django-wiki) under [www.example.com](https://www.example.com)
​
But I need to create others apps and install other packages like django-blog, create a custom system and add new ideas for further projects.
Should I have a virtual environment for each project?
/opt/wiki/venv
/opt/blog/venv
/opt/my-new-proj/venv
​
Creating different files to start/stop at boot using gunicorn under systemD or should I group the different projects under the same folder and overload the virtual environment?
If I keep the projects isolated, using Gunicorn I could create different files to use with SystemD. Is it fine?
​
Also, what happens with the Nginx config files serving different projects like
[www.example.com/wiki](https://www.example.com/wiki)
[www.example.com/blog](https://www.example.com/blog)
[www.example.com/my-new-proj](https://www.example.com/my-new-proj)
​
I would like to know your ideas and advice about good practices deploying Django apps.
​
Thanks in advance!

Django Saleor cms code explained
​
hello not sure if you anyone would be willing help but i have the python down and looking to dive down into the language more so i wondering if anyone could give me walk through of saleor code and help me learn of it all works togather.
example would be how saleor sends data from dashboard to database when i create a new product and what code is responsible for that?

[D] Great idea, how to publish?
I'm an independent software developer. While working on my own image processing project I invented a "thing". There is no reason to keep it to myself, as idea it's not patentable. What I'd like is to make it public and add something to my resume. What is the right way of doing it?
As for the idea:
1. It gives great, clear benefits.
2. it's generic and applicable in other domains as well.
3. it's intuitive. If I tell most of you will say 'nice' even before looking at the results.
4. it's easy to implement. I did it in pytorch, it's as easy to do in tensorflow or any other similar tool.
It would be quite popular, but I've seen nothing like this. So, I think it's something really new and worth publishing.

Simple Flask Apps (no db)
I'm teaching a Flask course at the moment, and the requirements are that students do *not* use a database (introduced next unit). There's no flexibility around this requirement.
​
What are some ideas for apps that students can create? Here are a couple I've come up with:
* Madlibs
* Coin toss
* Random numbers
* Random student from list
* Tax calculator
* Home loan repayment calculator
​
Some simple APIs that they've experimented with:
* Chuck Norris
* ISS

Trouble rendering wtform validator error
With the below I have a simple form with a text input box. I have set the `InputRequired()` validator on `SignUpForm`; however when I run localhost I don't get the validator message "Wrong value" if no input is supplied when I push the submit button.

[R] AdaBound: An optimizer that trains as fast as Adam and as good as SGD (ICLR 2019), with A PyTorch Implementation
Hi! I am an undergrad doing research in the field of ML/DL/NLP. This is my first time to write a post on Reddit. :D
We developed a new optimizer called **AdaBound**, hoping to achieve a faster training speed as well as better performance on unseen data. Our paper, *Adaptive Gradient Methods with Dynamic Bound of Learning Rate*, has been accepted by ICLR 2019 and we just updated the camera ready version on open review.
I am very excited that a PyTorch implementation of AdaBound is publicly available now, and a PyPI package has been released as well. You may install and try AdaBound easily via `pip` or directly copying & pasting. I also wrote a post to introduce this lovely new optimizer.
​
Here's some quick links:
**Website:** [https://www.luolc.com/publications/adabound/](https://www.luolc.com/publications/adabound/)
**GitHub:** [https://github.com/Luolc/AdaBound](https://github.com/Luolc/AdaBound)
**Open Review:** [https://openreview.net/forum?id=Bkg3g2R9FX](https://openreview.net/forum?id=Bkg3g2R9FX)
**Abstract:**
Adaptive optimization methods such as AdaGrad, RMSprop and Adam have been proposed to achieve a rapid training process with an element-wise scaling term on learning rates. Though prevailing, they are observed to generalize poorly compared with SGD or even fail to converge due to unstable and extreme learning rates. Recent work has put forward some algorithms such as AMSGrad to tackle this issue but they failed to achieve considerable improvement over existing methods. In

Just created my first web app using Flask and have a noob question
First off, Flask is really awesome. I’ve been programming for about 4 months now, and building this application was really cool, challenging, and sort of inspiring. The question I have is: is it possible to create the web server on say a Raspberry Pi, and then access it remotely from another machine? If so where would I look to learn how to do this?

Trouble with creating Dynamic forms
I am trying to create an application that displays a list of various questions.
Each question response in the list should be one of the following:
1. StringField()
2. SelectField()
The questions are dynamically generated from a database.
I am having trouble dynamically creating these form fields.

creating event model with recurring dates
hello.
im working on a project where users can list their events. In each event, it could either be a one-day event or a recurring event. How can I implement this application?
I've looked at other packages like django-scheduling, django-recurrence, and django-eventtools, but I don't know if they are compatible with Django 2.1.
It would be cool if anyone have any experience with these packages, and know if they are up to date with the current django version.
I am also willing to implement my own version of this system, but I do not know where to start.
thank you.
Edit: With this recurring events, is it possible to search for them based on date ranges

The Django Packages site needs a redesign ASAP
I hope i'm not the only one who really hate browsing it. Its really a bad showcase for the framework (let alone a web framework) when you can't even search packages on mobile. The comparison tables are also not responsive on mobile.
I'd really wish it had a better design. Take Laravel for example: [https://packalyst.com/](https://packalyst.com/)

How to create choices based on file contents

Build a Data Analysis Library from Scratch in Python
Hey All,
[Build a Data Analysis Library from Scratch in Python](https://www.youtube.com/playlist?list=PLVyhfExBT1XDTu-oocI3ttl_OPhulAJOp) is a course I've developed to help those looking for a long, comprehensive project that will teach advanced Python and basic software development. It seems that there is a lack of these types of projects for those who possess the fundamentals of Python, but haven't put together a complete project.
The end result is a library called Pandas Cub which is built to mimic the pandas library. There are 40 steps with nearly 100 pre-written unit tests that must be passed in order to complete the project. The project not only teaches advanced Python but environment setup, test-driven development, and developing code outside of a Jupyter Notebook. The project can also be [found on GitHub](https://github.com/tdpetrou/pandas_cub).
I hope its useful and if you have critical feedback please let me know.
