I love vacously truths (not sure if this is how you say it in English) All the people I've met in London were androids.

The term is correct. Grammatically, we would say, "I love vacuous truths", or, "I love vacuously true statements". (To my ear the second version sounds very slightly more appropriate, because in mathematics "vacuously true" is a bit of a set phrase, but both are fine.)

Always instantly consistent, always available, and perfectly tolerant of partitioning. Truly, it is the only database which can be scaled to unlimited nodes and remain fully CAP.

Is there a case where dev null can fail?

I can think of two: whe running out of file descriptors or memory. But then /dev/null1 would fail too.

Earlier quoted context omitted.

It's not a funny one if it was one. Of course something is going to be a bad database if it's not a database.

It's not a great joke, to be sure. But the essence of it is that it's a good database, by relevant but inappropriate standards.

Insufficient/incomplete rather than inappropriate, perhaps?

Enterprise DBAs will nevertheless provision separate /dev/null0 and /dev/null1 devices due to corporate policy. In the event of an outage, the symlink from null will be updated manually following an approved run book. Please note that this runbook must be revalidated annually as part of the sarbox audit, without which the null device is no longer authorised for production use and must be deleted

/dev/null is not a database. By this logic is a hard disk a database, is a CD a database. No. They are storage mediums. You could store a database on them, but they themselves are not a database. Considering there is no way to read back data written to /dev/null it will not be useful for storing database data.

What a weird title, you can say it's ACID but it's not a database

> What a weird title, you can say it's ACID but it's not a database You’re right, we should ban jokes that aren’t 100% correct!

Sorry if you feel my words mean. I'm not criticizing the joke, I just think it could make a better title, even for a joke, by adding quotes around "database" or calling it a "storage service," since it does allow data to be read. A good joke is both entertaining and difficult to deny.
