PyUpdater is no longer maintained. What now? - Tufup: automated updates for stand-alone Python applications.

Hello world! I want to recommend a wonderful open-source package called **Tufup.** It's a simple software updater for stand-alone Python *applications*. This package was created as a replacement for **PyUpdater**, given the fact that [PyUpdater has been archived and is no longer maintained](https://github.com/Digital-Sapphire/PyUpdater#this-is-the-end). However, whereas **PyUpdater** implements a *custom* security mechanism to ensure authenticity (and integrity) of downloaded update files, **Tufup** is built on top of the security mechanisms implemented in the [python-tuf](https://github.com/theupdateframework/python-tuf) package, a.k.a. **TUF** (The Update Framework). By entrusting the design of security measures to security professionals, **Tufup** can focus on high-level tools.

Do note that, although **Tufup** offers the same basic functionality as **PyUpdater**, there are some differences:

* **Tufup** uses [python-tuf](https://github.com/theupdateframework/python-tuf) to secure the update process. This means you'll need to understand a little bit about the principles behind [TUF](https://theupdateframework.io/overview/). You can tailor the level of security to your needs, from highly secure, to slightly secure.
* **PyUpdater** was tightly integrated with [PyInstaller](https://pyinstaller.org/en/stable/), but **Tufup** is not. You *can* use **Tufup** with **PyInstaller**, as illustrated in the [tufup-example](https://github.com/dennisvang/tufup-example), but it is not required. You can also use it with any other packaging method, or you can even distribute a plain python script or just any directory of files.

Per object caching using django-cacheops, or django-cache-machine

I'm working on a project: multi-user, a very large database that grows daily, and some complex queries that do things like aggregations an sums on that data. The stack is Django and DRF and the users do queries like `api/customers/` where the list of customers might have some overlap between users if the two users are in the same group.

Is there a way to do per-object-caching on the data retrieved so that if 2 users in the same "group" do a query for "customers" the first time it happens with user#1 the API hits the DB, but the second time when user#2 (in the same "group") it is a cached query and thus much faster? Also I'd like to do aggregations or filtering on the cached version when possible rather than doing an SQL query with the filter parameters.

Is this possible with django-cacheops or django-cache-machine

Async proxy view for map layers in my app - is this a bad idea?

We have a mature Django app used as a user and sort of data management system (geospatial data layers). The app currently only tells our frontend which users are authenticated and gives them a list of authorized layers that is served by another "dumb" app (QGISServer). I say dumb since it doesn't know about our users. Just a nginx sub request Auth system is used.

Now we will need to add other map servers, which my require their own authentication that can't be client side, so my plan is to create a new Django proxy view. This view will deal with authentication and authorization of layers using async ORM as well as act as a proxy auth and cache to external servers. It will use async aiohttp to fetch the response tile from the mapserver, cache it in redis, and return it.

The problem is that map tiles get requested by the frontend Open Layers easily 10 at a time when you pan. And it can take a second to render the tile, download it to the proxy and then push to the client. 10 of these at a time would kill the app for a second if it had 10 wsgi

Hitting a learning wall at application factory pattern

After a month of doing this every day i’ve become really comfortable with setting up and deploying new flask apps and deploying them. I now understand the usage of blueprints, and while from an outer perspective I understand why an application factory would come in handy for large apps, I just cannot wrap my head around how the setup actually works. Every tutorial becomes so complicated very quickly and I can’t seem to find any simplified examples.

Looking for any recommended tutorials or tips to push through this wall.

How does a single running instance of a Flask application handle multiple requests at once? Is it all async or multithreaded? Or handled by the webserver (NGINX, gunicorn, etc)?

Say I had a single Flask application running on an EC2 instance, and 300+ requests were made from other machines at about the same time. How does Flask handle this? Does it spawn new threads and bounce control around?

Collaborative Jupyter Whiteboards

I found a common occurrence in data science type of meetings is someone screen-shares their Jupyter notebook either by Zoom, Hangouts, or conference room display and then starts scrolling through it explaining their tables, plots, markdown, Latex, etc. When I want to ask a question about a plot that the presenter scrolled past, there's a lot of "can you scroll up a little, no too far, back down a little". If I want to point to an area of a plot or column in a table, I can do it in Zoom, but it's all out of place once the notebook is scrolled. Usually someone has to ask the presenter to zoom in to see some tiny Matplotlib font.

This led me to start looking into multiplayer versions of Jupyter that strive to be like Google Docs. There's proprietary ones like CoCalc and DeepNote, then there's open-source work underway to add real time collaboration to JupyterLab using Yjs. All of these are geared towards collaborative editing of the notebook code, but I really needed and saw a use for was collaborative viewing of the results contained in the notebook. Since notebooks usually have access to lots of valuable data, IT can

Generate image in pdf via pdfjinjax

Hi so I am using this library https://github.com/edgaraafelix/pdfjinjax pdfjinjax a fork from pdfjinja I believe both examples were already in pdf format and upon checking both sample.json and example.py the field signature was just a file path and it was already instantiated the image once the pdf created.

But I had a pdf from scracth and I do not know what field in LibreOffice to use for that effect. I tried Image control, Image button but image was not created. In textfield it just paste the file path and not rendering.

In django use, I need to send a file back to the user with premade pdf :) and it needs the image for the header.

So any experienced user used that library how to achieve that? Thank you.
