I read the AskReddit thread on "What costs less than $100 that changed your life?" (link unavailable since I'm at work) but someone responded "SQL" - jobs just open up that make a ton of money.

I did a cursory search on Indeed and holy moly they were right -- SQL jobs get easily 2x what I make now. I'm pretty good at Excel and that sort of thinking, so I was thinking I'd try taking a class.

Do yall have any recommendations as to a good course to take in SQL, preferably online, preferably free or cheap? I'm willing to pay a bit if it'll mean I can make a lot more, but I'm currently not making a ton, haha.

Any responses welcome, including ideas as to how to break into like, tech-oriented fields as well.

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?

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
