Since no one has posted this yet and the day approaches the end (UTC), I decided to post this...

General Programming Q&A thread! Ask any questions about programming, answer the questions of other users, or post suggestions for future threads.

Don't forget to format your code using the triple backticks or tildes:

Here is my schema:

```sql
CREATE TABLE article_to_warehouse (
  article_id   INTEGER
, warehouse_id INTEGER
)
;
```

How do I add a `UNIQUE` constraint?

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 week. Did you accomplish any goals? Suffer a failure? Do nothing at all? Tell us about it!

Spring is here (at least in the northern hemisphere, sorry Aussies and Kiwis) and it's now warm enough where I live to roll the windows down while driving.

I'm looking to expand my playlist of, like I said in the title, music that will make me want to roll my windows down, turn the volume up, and exceed the speed limit.

For an idea of what I'm looking for, here's some tracks on my current playlist. This skews towards metal because of my own personal tastes, but I'd welcome recommendations from any genre:

• Immortal - One by One

• Bathory - 109 and Death from Above (paired songs about bombing a city in WW2, from the perspective of a German Me-109 fighter pilot and a B-17 Flying Fortress bombing crew)

• Fleetwood Mac - The Chain

• Hank Williams III - Rebel Within

I need to read some fiction children books about death (for research) -- any age group preferably for young children.

Stories both realistic and fantasy/fantastical that doesn't gloss over the suffering and pain children can experience, possibly with dark overtones.

Stories featuring Death as a character would be great too.

Thanks!
