This may seem an obvious question, but not as much as it seems. She uses Windows, I’m currently using Linux/macOS. How to instruct her to install her Python environment? Should I use Zoom, Skype, Google Hangouts, or another solution? Is there and easy way for live-drawing (online blackboard) to explain things to her visually? And, perhaps most importantly, how can I do that for free?

How do I add a `UNIQUE` constraint?

Following up on @freddy's query about self-hosting ...

I am trying to set up a self-hosted VPS running Synapse (the server-side component of Matrix), Riot-web, and bundled in Jitsi. I've twice gotten it up and running successfully for internal accounts/users, but federation keeps throwing weird authentication errors when trying to connect with user accounts from other server instances (a week later, my regular Matrix account still has 3 outstanding broken Invites from the new server-account which I can neither accept nor reject ... ).

I'm basically following along with this youtube setup tutorial (except I am using Apache rather than nginx).

Before I start to drill into the nitty-gritty of my issue(s), does anyone here have experience setting this up? Anyone care to dedicate a bit of time and energy to helping me figure out what I'm doing wrong?

Additionally, I saw commentary from @smores that Jitsi isn't performing well for him on his self-hosted server ... any further details you can share?

Edited to add:

Sorry all, I didn't think through the timing. I am still motivated to get a self-hosted Matrix instance up and running; however, right at the moment, I have a couple of other, higher priorities I need to attend to first. If I'd thought about it, I would have held off on starting this thread for a couple of days.

I will get back to this thread ... let's say, Wed or Thurs ... take another crack at the Matrix set-up then, and provide details here, as I do.

Thanks,
EtC

I’m currently studying Python Object Oriented programming and got to a point where logic and syntax are the least of my problems. I always get to a stage where I’m completely lost between modules, classes, objects and a sea of “selfs”.

I’m not doing anything too complicated, just small projects for practice, but I think I would benefit from planning. My mental processes are highly disorganized (ADHD) and I need all the help I can get with that.

I don’t need an automated tool (even though it might come in handy) -- sketching things out on paper is probably enough.

I only know about UML, which seems fine. Can anyone recommend a tutorial about this and other tools?

Edit to link my last attempt at following a tutorial:

This is the last tutorial I tried to follow, a Pygame project from the book Python Crash Course 2ed. Following tutorials is frequently mostly typing, so what I achieved there is not a real representation of my abilities -- I would not be able to do something like that on my own. In fact, I failed to answer the latest exercises, which were basically smaller versions of this project.

My problem is not with syntax and the basics of how OOP works, but rather with memory and organization of information.

Sorry if this is a silly question, but I keep running into situations where a small CLI or GUI tool that could be handed a single file and hand me back an encrypted version would be useful. I've done some googling, but all I typically turn up is blogspam about random Windows-only tools that seem to be of dubious quality.

Anyone know of a good tool for this type of thing?
