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.

Hash, displace, and compress: Perfect hashing with Java
...sounds like quite a niche use-case, but I agree that I cannot think of any other stream-hashing library. I hoped https://github.com/OpenHFT/zero-allocation-hashing would do, but it doesn't. However, https://github.com/OpenHFT/Chronicle-Bytes has xxHash if that's your thing.

The Smallest Hash Table
Yes! That's the implementation from the paper. There's also a Java implementation: https://github.com/thomasmueller/minperf

Hash, displace, and compress: Perfect hashing with Java
I understand this is mostly educational. However, there is a Java library for perfect hashing, https://github.com/thomasmueller/minperf. I used it once, it wasn't the fastest thing in the worlds, but it did the job.
What are some alternatives?
hash-checker - Fast and simple application that allows you to generate and compare hashes from files and text
FastHash
password4j - Java cryptographic library that supports Argon2, bcrypt, scrypt and PBKDF2 aimed to protect passwords in databases. Easy to use by design, highly customizable, secure and portable. All the implementations follow the standards and have been reviewed to perform better in the JVM.
hash4j - Dynatrace hash library for Java
Chronicle-Bytes - Chronicle Bytes has a similar purpose to Java NIO's ByteBuffer with many extensions
argon2-jvm - Argon2 Binding for the JVM
sirix - SirixDB is an an embeddable, bitemporal, append-only database system and event store, storing immutable lightweight snapshots. It keeps the full history of each resource. Every commit stores a space-efficient snapshot through structural sharing. It is log-structured and never overwrites data. SirixDB uses a novel page-level versioning approach.
DeadHash-android - DeadHash for Android
HikariCP - 光 HikariCP・A solid, high-performance, JDBC connection pool at last.
