How do I add a `UNIQUE` constraint?

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

Did anybody else back this when the kickstarter was happening?

Remember in the early 90s when you'd go to the local computer swap and sniff cards to see if they were fried or not? When you got a bad one, this is that exact smell.

I received mine today and I have to say, if you love the smell of solder / welding, raspberry, cheap alcohol, and suffering -- this is the scent for you!

This is easily the worst smelling fragrance I have ever experienced. So bad, in fact, that if there is ever an opportunity to go to space, I will respectfully decline.

This was the first campaign I backed. It took roughly eight months for everything to come together... and it really has me questioning this model. So my question is, what have you backed and what was your experience?

SpaceX's announcement: https://www.spacex.com/updates/inspiration-4-mission/index.html
Mission website: https://www.inspiration4.com/

The flight, dubbed Inspiration4, is being paid for by Jared Isaacman, of Shift4 payments. He's taking three other people with him. The seat dubbed "Generosity" is being raffled for donations to St. Jude Children's Research Hospital. The "Hope" seat will go to a St. Jude ambassador. The "Prosperity" seat is a "Sign up for my company and tweet about it" thing.

Unlike the current tendency, unless I'm playing with my real-life friends, I don't care for multiplayer in shooters. I'm usually surrounded by highly skilled players that seemingly dedicate their lives to becoming experts in that game. I don't wanna become actually skilled, I wanna play in my own way and feel I am skilled in face of limited AI. You know, fantasy!

Most franchises are leaning towards multiplayer, and my playstyle is quickly becoming old fashioned. I recently purchased the Xbox Series S and would love suggestions of great shooters with a focus on offline missions. Especially historical shooters (like WWI and WWII), but not limited to it.

Thanks!

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their weekend. Did you make any plans? Take a trip? Do nothing at all? Tell us about it!

This thread is posted weekly, and is intended as a place for more-casual discussion of the coronavirus and questions/updates that may not warrant their own dedicated topics. Tell us about what the situation is like where you live!

Have you been socializing with friends or family using Zoom, Hangouts, Skype, Facetime or the like during the pandemic? Beyond the typical chats, meals and drinks, what sorts of activities have you been engaging in over these services? Games? Karaoke? Watching movies? What sorts of activities have been the most successful or lent themselves to working remotely?

In a previous thread, we discussed "What's hard about being a man?" The responses were, I feel, incredibly valuable (and that thread is still open, so please contribute to it if you want to answer that question!). I want to add to that thread by asking the same question relative to women and non-binary people. I'm wanting to do this not as an attempt to put responses or identities in competition but because I feel each question is valuable on its own terms for focusing on a specific identity and experiences related to it.

Non-binary folks, I'll put up your thread a few days from now, as I want to allow each thread to have its own lifecycle independent of the others.

For this thread, I want to ask the question: "What's hard about being a woman?"

As in the previous thread, I want this to be a place where people are able to share open and honest truths about themselves, even if those are difficult or revealing. Please be mindful of the atmosphere of the post and the lived experiences of the individuals posting and try to keep things not only civil but welcoming to them. The principle of charity asks us to interpret others' comments in their best light, not their worst!

Responses are open to all identities, as, again, I believe that anyone can have insight into this and I want the thread to be open to questions and discussion, but I am going to ask that anyone responding keep in mind the underlying demographics of Tildes which lean very heavily male. I think this thread will be most valuable if we elevate and genuinely listen to women's voices. It does not mean that only women are allowed to participate in the thread, but I ask everyone to consider how, without this in practice, a majority male population can produce a majority male view of womanhood.
