LightGBM
A fast, distributed, high performance gradient boosting (GBT, GBDT, GBRT, GBM or MART) framework based on decision tree algorithms, used for ranking, classification and many other machine learning tasks.
That's a tough bouncing ball to follow as it seems the resolution was to upgrade to a newer version of a dependency, but if we look at that dependency, the fix seems to be found somewhere in this https://github.com/microsoft/LightGBM/compare/v2.2.1...v2.2....
But, although there is admittedly a lot in there and I may have missed it, I don't see any updates to tests to denote that a problem was discovered. Which, while not knowing much about the project, makes me think that there really isn't any meaningful testing going on, which is interesting for what it is, but not in the vein of the discussion here.

NebulaGraph Database
A distributed, fast open-source graph database featuring horizontal scalability and high availability (by vesoft-inc)

ydb
YDB is an open source Distributed SQL Database that combines high availability and scalability with strong consistency and ACID transactions
The idea to create this extension came to me by chance: I was studying different JOIN algorithms and came across it. An Internet search didn't turn up anything like this for PostgreSQL, and I realized that I had to do it myself. Who immediately wants to see what happened, here is the link to the repository. In the context of the core of the algorithm, I did not bring anything new, on the contrary, I copied more from others. Before starting to implement my own, I looked at the implementations in several databases, in particular, YDB, MySQL and DuckDB. If someone wants to learn DPhyp by code, I recommend looking at code YDB — Clean and clear, very easy to read. But I didn't start with YDB myself, but with MySQL, and now its implementation has been significantly changed and optimized, it won't be possible to figure it out right away, only based on the comments and with the initial understanding of DPhyp itself.

areg-sdk
Remote objects act local. C++ Async RPC for threads and processes with auto-discovery and zero-boilerplate messaging.
Long time I was not here and I am very sure that none missed me :) I was busy developing new features of areg skd and creating user interface tool for areg sdk. And I must say, that working almost alone for more these 2 project, I made a huge progress. And what is very important, I have fun.
