Zip trees are great! For a project I made a version that uses the memory location of the entries to construct the (random) rank on the fly. So it’s a binary tree structure that requires the same memory as a linked list (two pointers) only! https://github.com/open62541/open62541/blob/master/deps/zipt...

There's quite a bit of OPC UA bashing across this project. So let me chime in to keep the "balance in the universe". OPC UA is a protocol to interact with an object-oriented information model. Basically CORBA done right to use object-oriented principles and reuse software components in industrial automation. Since OPC UA is a protocol, its performance depends mostly on the implementation. Some PLCs may be crappy. But that doesn't translate into bad performance overall. My experience goes to the exact contrary. Full disclosure, I lead-develop and maintain an open source OPC UA implementation that sees quite a bit of use by the big guys in the automation domain. We use C for performance. And we do have funding from the industry. https://github.com/open62541/open62541 But yes, it is hard to break into this world. Especially since solutions h

OPC UA (IEC 62541) provides a robust platform-neutral information model, and multiple options for transport. Similarly, it specifies events, subscriptions, discovery and several higher-level abstractions (e.g. alarms and programs). In some sense, it's a cross-platform successor to COM/DCOM. Some open source implementations are incomplete, but work continues. https://en.wikipedia.org/wiki/OPC_Unified_Architecture https://github.com/open62541/open62541 https://github.com/OPCFoundation You may also find Woopsa interesting, depending on your use cases. http://www.woopsa.org/
