What exactly is caching and how do I add it to an app I have on heroku?

I have a data science type application where I am getting public information from FPDS and SAM gov't website. The site is currently on heroku.

I would like cache views so if a person is researching more than one company they can quickly go back to earlier pages without having to fetch the results from the database everytime.

Based on my limited knowledge that is what casheing does?

Second, I am looking at [flash-caching](https://flask-caching.readthedocs.io/en/latest/#) and it doesn't appear to be that difficult to implement to the route's I would like to cashe.

The question is on heroku, you wouldn't use `simplecashe` would you? Would you use a different cashe strategy? From the docs the `CASHE_TYPE` can be `simple`, `redis`, `memcached` and serveral more. On heroku would I need to store the cache on something like redis or can I store it in memory?

A tool to generate Jupyter notebooks programmatically

I recently found myself needing to generate many Jupyter notebooks in different directories, that were all very similar, save for a few differences in a variable name.

Hence, I decided to write a Python script that generates a Jupyter notebook from an input template:

What is flask used for

Hi, I am currently learning flask but would like to know how exactly are flask applications used in software development of companies.

For instance if a company is using the MEAN stack, where do the flask applications come into play?

The tutorial for the flask framework illustrates its use as a web application. However if I only need it as a web server, do I need to care about the templates?

Thank you all in advance! I’m a beginner in software engineering and would like to have a fuller picture of how different frameworks come together in a company.

Edit: Grammar

How to prevent a customer from adding items just before the Confirm Payment button is clicked?

First, I am sorry I post it here because r/webdev is all about frontend, and r/backend is empty.

Currently I am working on an ecommerce project based on django-oscar. Since its accompanying paypal integration library is abandoned(and it's a two-step checkout), I decided to use BrainTree SDK to implement Paypal Express Checkout. Paypal EC gives you a button on the final review page that customer can click to have a pop-up window that they can login to paypal and pay.

The problem is, on the review page, the button needs a pre-determined checkout amount. That means when the page is generated, it has to fill in the button with the amount in the cart. If the customer add items after the review page is loaded but before clicking the button, the checkouted cart will have more items than those are paid.

I know django-oscar has a "freeze basket" function. But it will remove all items from the cart. I think a good place to call it would be during the review page generation. But I can't think of a reliable way to determine whether and when to restore the cart if the customer stops at review page and decides to checkout later, which I think would happen quite a lot.

Thanks for your help!

Widgets wont show in HTML/Azure/NBViewer

So from my running my notebook the widgets work fine, but saving them as html, uploading them to azure/github/nbviewer and then opening them through the link, the widgets don't display.

With a basic example I get "
interactive(children=(IntSlider(value=5, description='n', max=10), Output()), _dom_classes=('widget-interact',…"

displayed where the output widget should be.

Is there any way I can share my notebook so that the other user does not need to install ipython/jupyter to see the widgets?

[D] Why is Z-dimension for GANs usually 100?

I'm playing around with GANs, I've got a question which I can't find answer for. Why is Z-dimension (random vector noise) for GANs usually 100? I saw a lot of GitHub projects and online tutorials, seems like the random vector has always the size of 100. Is it confirmed that it gives the best results? What if I changed that to e.g 1000? How does it affect the generated images?

Migrating database(MySQL to PostreSQL): Attach migrated database to application

Good day,

I would just like to get some idea/s on how to do this task properly. I am a newbie in programming and got a job as Django Dev. My current task is to migrate a MySQL to PostgreSQL. Reading resources online, I found out this tool which helps me do a test migration in my local environment [https://github.com/dimitri/pgloader](https://github.com/dimitri/pgloader) .

MySQL database has 70 rows. I can confirm that when I access postgresql in cli, I can see all the tables as well as the data. Now my problem is, this is my first time to perform this kind of task. I have no idea how will I attach the database to our applications. The rows and fields from mysql database are not matched fully identical to our fields in [models.py](https://models.py) . Perhaps typing manually to admin is an option but its tedious especially if we will encounter this task again. I am planning to automate it.

Can someone share some light here to a newbie? Sorry for the long post, I just don't know how to approach this.

Thanks,

J
