Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Gem adds support for creating state machines for attributes on any Ruby class
I worked on a state machine framework in another language, and have definitely have found less terse to be pretty good. Typing a few extra characters isn't that bad, especially if it makes some awful bit of evented code easier for someone to understand.
Of the things available open source, I think P-lang is pretty cool: https://github.com/p-org/P/blob/master/Tutorial/1_ClientServ...

The TLA+ Video Course
I’ve gotten a lot of good about TLA+ and the more recent the P language has been really promising lately. It’s got a good pedigree and is being increasingly used as AWS as well.

Learn TLA+
I tried to use TLA+ but what annoys me the most is the disconnection between the actual implementation and its code. I think the P language has a much better future just because it can generate code that works: https://github.com/p-org/P

Let's build a distributed Postgres proof of concept
It is tough.
My approach when learning new protocols like Raft or Paxos is to implement them in Pluscal (TLA+'s higher-level language) or P (https://github.com/p-org/P). I've found that helps separate the protocol-level concerns from the implementation-level concerns (sockets? wire format?) in a way that reduces the difficulty of learning the protocol.

A lightweight YugabyteDB docker image for CI/CD
When it comes to production, it is recommended to use the official docker image for YugabyteDB. You can either obtain it from Docker Hub or build it yourself using the Dockerfile. If you are using CI/CD pipelines, it may be helpful to reduce the size of the image. One way to do this is to remove the debug symbols from the compiled binaries. These symbols are useful for troubleshooting but not essential for automated testing. If you encounter any issues, you can easily reproduce them using the regular image.

Multi-region YugabyteDB deployment on AWS EKS with Istio
YugabyteDB is a transactional database that brings together four must-have needs of cloud native apps – namely SQL as a flexible query language, low-latency performance, continuous availability, and globally-distributed scalability. Other databases do not serve all 4 of these needs simultaneously.

Best Practice: use the same datatypes for comparisons, like joins and foreign keys
It is possible to apply Batched Nested Loop but with additional code that checks the range of the outer bigint and compare it only if it matches the range of integer. This has been added in YugabyteDB 2.21 with #20715 YSQL: Allow BNL on joins over different integer types to help migrations from PostgreSQL with such datatype inconsistencies.

Is co-partition or interleave necessary in Distributed SQL?
Therefore, interleaving or co-partitioning is probably not necessary, and would reduce agility and scalability more than improving the performance. Unless you have a good reason for it that you can share on Issue #79. But, first, test and tune the queries to see if you need something else.

PostGIS on YugabyteDB Alma8 (workarounds)
This is a workaround, not supported. I've opened the following issue to get it solve in the YugabyteDB deployment: https://github.com/yugabyte/yugabyte-db/issues/19389

Bitmap Scan in YugabyteDB
Note that there may still be a need for bitmaps, especially with disjunctions (OR) as the following is about conjunction (AND), and it can still be implemented, differently than PostgreSQL. This is tracked by #4634.

YugabyteDB official Dockerfile
You have seen me using the official YugabyteDB Docker image extensively. This image is suitable for various purposes, including labs, development, testing, and even production. In the past, we used to create it internally due to its seamless integration with our build process. However, some companies prefer to construct the image on their own, which is indeed a commendable practice. After all, it's not advisable to run random images with root privileges on your servers. As a result, we have made a significant alteration by introducing a refined Dockerfile to our Github repository.
