Here is my schema:

```sql
CREATE TABLE article_to_warehouse (

```

How do I add a `UNIQUE` constraint?

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!

There are very serious articles about young adolescents being radicalized into fascist movements and personal testimonials of such in YouTube, along with many videos, most commonly by leftists about how this works and very rarely a guess at what to do about it.

There are also often memes about young people entering politics, like this video or this video assuming that and then satirizing how young, presumably privileged people when it comes to social matters (because otherwise bad personal experiences will inform your beliefs and this will be more than a poorly done intellectual exercise to you) flip flop between every political belief like it's nothing, alongside memes satirizing how young conservatives are introduced to their politics by edited clips of what are supposedly SJWs out of context and how farcically (distressingly) ridiculous it is to be introduced to your beliefs by these videos, especially when these sometimes real but extreme regardless examples of the left's presumed irrationality are much less harmful than the conservative extremes.

A lot of this talk and memes concerns or satirizes radicalization of people after they've been politicized and occasionally in the case of the serious articles, what to do with it. But I feel this focuses more on the consequences, which is fine, but not everything worth looking at.

So back to the title question, how do you think someone/people should be politicized?

For example:

Bing
DuckDuckGo

Baidu obviously doesn't show tank man, but rather an assortment of random tank images

Yandex and Google seem to show the results no problem. Would be curious to know for you Tilderinos outside the US if the same results apply to you?

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!

What have you been watching and reading this week? You don't need to give us a whole essay if you don't want to, but please write something! Feel free to talk about something you saw that was cool, something that was bad, ask for recommendations, or anything else you can think of.

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL, or any other database you use!

I'm creating the concept for a story called The Little Differences. It's about an accountant that, one day, out of the blue, notices that a certain calculation is producing a slightly wrong result. Barely noticeable, nothing world-changing,

He runs it on the computer, tries different software, a physical calculator... everything gives a result that's a little off. When he checks on paper himself, he gets the correct result. But, to his surprise, everyone else tells him that he's the one that's off, and that the incorrect result is actually perfectly sound.

I need something that makes sense, mathematically. The weird result must be something that really is wrong, and not just something that programs sometimes get wrong (I don't want it to be explained at all... I mean, the reason why it is occurring must not be something easily reducible to some well-known malfunction). But it must also be minor enough for someone to miss, something that wouldn't really cause much trouble in the real world (is that possible? IDK).

Lastly: it must be something that I'm able to explain (on some level) to a non-math reader.

So, Tildes math wizzes, what you suggest? :D
