Nor have I; I think it is just what the developer of tree has chosen to call file descriptor 3, rather than being a wider convention or standard thing provided by the environment.

> As of version 2.0.0, in Linux, tree will attempt to automatically output a compact JSON tree on file descriptor 3 (what I call stddata,) if present

That depends what you mean by needing a database. MBtiles files are SQLite database files, so you need a SQLite process running somewhere to extract the requested tiles.

Looking at the page source shows that it is vanilla JS [1] with a few libraries:

* https://barba.js.org/docs/getstarted/intro/

* https://swiperjs.com/

thanks, looks like it's leader-line that does most of the layout. I couldn't find it earlier on google, but now I see that was because the helpful AI had some stuff about fishing and I missed it.

> Not the same email.

I'm not even sure they're both emails. The first looks like a fairly conventional mobile email app; the second looks like a messaging app.

Not only does it not have a 'from' and 'to' field, it also doesn't have a 'subject' field.

Thanks, makes sense.

Apaprently there's an "Office Furniture in London" that might be it: https://www.officefurnitureinlondon.co.uk/product-category/s...

Their online listings for Aeron chairs are for more like £400, but that's still less than a third of the price when new.

"Abuse of notation" is a commonly used term: https://en.wikipedia.org/wiki/Abuse_of_notation

> I wonder how this process worked in practice. Do you simply send your only one set of hard disks and hope for the best?

No, you don't put your own disks in the Snowmobile/Snowball/Snowclone. It contains disks, so when it arrives you connect it to your network and copy data onto it, and then it is driven to an Amazon datacentre.

See, e.g. https://docs.aws.amazon.com/snowball/latest/developer-guide/...

https://aws.amazon.com/blogs/aws/aws-importexport-snowball-t...

Thank you. That makes much more sense. So this way once the data is on the AWS device it is Amazon.com's responsibility so the customer doesn't need to worry about the truck or whatever.

And if there is an accident on the road, bad luck. /s

The usual example used in teaching is Ansombe's Quartet: https://en.wikipedia.org/wiki/Anscombe%27s_quartet

It consists of 4 datasets with the same summary statistics, but when plotted look very different. It's much easier to see the patterns in the plots than in the data table.

Thanks for that reference.
