@ggn @tattlemuss @loke I actually work on a platform where a boolean can be true, false or null.

@zerkman @ggn @tattlemuss @loke Wow, the fact that X and W are distinct is particularly impressive!

@Lacey @ggn @tattlemuss @loke I have never encountered real life use cases for these 'weak' signal values. Maybe it's used on some mixed analog/digital simulators?

All others are actually useful.

@Lacey
Databases? Booleans are three state logic in some databases. Oracle for one. As you say, true, false or null.

@NormanDunbar @Lacey @ggn @tattlemuss Oh, Oracle and their null behaviour. In Oracle, an empty string is null. Oracle is not short of bizarre features, but this one is one of the more annoying ones.

@loke @NormanDunbar @Lacey @tattlemuss I consider a feature their clause that prohibits the publishing of any benchnarks. And (without having any direct experience with their products) that is the one that really gets me

@ggn @loke @Lacey @tattlemuss Larry Ellison rules at Oracle. What he says, goes, no matter what. And he's rumoured to be a twat! Which might be true given he's also a Trump supporter. 😟

@loke @Lacey @ggn @tattlemuss Aye. An empty string is not NULL! Even to use Oracle DBAs. We have no idea why the designers of the database decided that it should be!
