How do I add a `UNIQUE` constraint?

Have you watched any TV shows recently you want to discuss? Any shows you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

You could look up, say, CMSes, get some basic info about each one (to make useful decision), and learn who its active committers were. The site closed, I know. Do you remember its name? Or people who were part of it?

I asked someone to write an article for me about "review sites for open source" -- think Yelp for Software -- and neither of us can remember its name. But if you have others that you think should be included (for positive or negative reasons), please let me know.

I recently got my significant other into Eurotruck Simulator 2 and was given the go-ahead to purchase a VR headset so that we can better experience the various sim games out there. Unfortunately, the complete Valve Index package is back-ordered about 8 weeks so it will be a while before I can take the plunge and buy one.

Was just curious though if anyone here also has a VR headset and what their experience has been with it. I had a 1st generation Oculus Rift a long time ago but ended up selling it since I felt the software wasn't there (2016) and I could really only play the seated experiences with a 360 controller so I felt I was behind the curve even on my 1st purchase.

Some prompts to help spur discussion, but feel free to share what you would like to share:

• How often do you play on your headset?
• What games/experiences would you recommend?
• What games/experiences do you not recommend?
• What headset do you own/have you tried any others?
• Are there any accessories or peripherals that are worth checking out?

As life slowly returns to normal in the UK, I've felt the need to look after my fitness more. I lacked discipline throughout lockdown to workout at home and keep my fitness. As a result I've got a nice COVID-gut, and my endurance and strength are shot. I swam regularly before quarantine hit, at least 4 times a week, and I'm keen to get back into that. But I'm also looking at picking up a martial art, for a more intense workout and fitness, as well as just to pick up a new skill. However I have no idea where to begin with martial arts, so I figured I'd start a thread for some inspiration, and go from there.

So are any tilderen martial artists? If so, tell me about it!
What do you practice?
How long have you done it?
How does it benefit you?
Do you attend classes or practice solo?
Would you recommend your martial art to a beginner?

I'm building a playlist with that classic exercise montage aesthetic. Right now it's a bunch of new retro wave, montage tracks from Rocky, Top Gun, Rad, Karate Kid, etc.

Temporary playlist

If you have any suggestions for tracks that maintain this aesthetic, it'd be appreciated.
