why the hate on DDS?

seems like a perfect fit.

DDS is the least bad of the stuff that has come out of OMG, but it's not a nice middleware still. There is no underlying algebra of that composes nicely when compared to Zenoh for example, and the "vendor independence" and compatibility is usually a joke. There's a reason ROS is moving away from it again.

There's a standard that has OMG as the acronym? OMG. I'm not even going to bother to search for that!

Object Management Group I think. Better known as the inventors of UML.

UML was phase two of OMG. It originally developed CORBA.

"The horror, the horror."

Forgive the ignorant question, what made CORBA terribile?

I only used it during university and it seemed overengineered but it mostly worked, and I vaguely recall IDL to be nice.

I'm guessing interop was actually atrocious?

Synchronisation based on spooky action at a distance of mutable objects.

CORBA had the concept of distributed objects which is a terrible idea in practice.

Also BPMN, CORBA and UPOS/JavaPOS.

It's funny that you can legitimately just add " - OMG!" in the slang acronym meaning after any of its creations' names.

They also merged the concepts of Working Group and Task Force into an Open Management Group Working Task Force, or OMG/WTF.

Do you have any references for this? It is quite a bold statement to make without any basis to validate it against.

I'm asking as I'm not a fan of DDS, so very curious the direction they are actually heading into, and I haven't found a reference for this yet.

omg is retarded

Using DDS to deliver data to X machines over multicast, with some real time (soft) QOS is a powerful solution.

For things like avionics, industrial automation, etc.

I think if the server world ever thought about the advantages of multicast, it might solve some problems there.

There are about 5 viable vendors in this space, and about 6 open source projects out there floating around.

And interoperability between vendors is very good. IMHO.

DDS is terrible.

DDS is hard. But we have agents now.
