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.

Java 20 looks like it may be one of the biggest updates in years
There are plenty of vendors providing builds of OpenJDK free to use in production including Oracle themselves. Oracle's build of OpenJDK that is free to use in production is found here: https://jdk.java.net.

Java can also be found in OpenJDK. Download your version, extract it (usually, the default directory is /usr/lib/jvm), and point the java program.

Is Java8 still free for commercial use? I haven't done any Java work in a long time. I was under the impression that lots of people were still using java8 because it was exempt from the commercial licensing of later versions. If you're paying for Java, is there any reason not to upgrade to 17?
As someone else has mentioned, Oracle JDK still has limitations when used in commercial applications. However, there are lots of JDKs that are free to use for anything you want to do with it. jdk.java.net is where I used to get mine from. If you want an installer adoptium.net is also great (that's the JDK provided by the Eclipse foundation).

What's with the multiple different versions of Java/OpenJDK, and why does java.com link to Java 8?
Java.com is the website for the product Java. Oracle owns java as mentioned in 1 so it makes sense they would have java-related things on their website. jdk.java.net is the domain for the Oracle OpenJDK

Marketing email about Java licensing? We are a .net shop with only 2 third party apps built on Java for part of our business. We get a patch from the vendor and apply it. That’s all our java patching. Anything I actually need to worry about?
This, the oracle JDK from oracle.com.. Not the Oracle build of the JDK from http://jdk.java.net/ which has always been free.

OpenJDK vs Oracle JDK?
https://jdk.java.net/ is probably the most standard as those are the build from openjdk itself. The eclipse temurn is a different Openjdk build by a different organization.

Amazon Corretto, Microsoft Build of OpenJDK, Red Hat Build, IBM Semeru, Oracle, or something else?
OpenJDK is an open-source project. The key word there is 'source'. OpenJDK does not provide binary distributions. Yes, there is one available from jdk.java.net but that is the Oracle OpenJDK JDK.

> Yes, they're changing one aspect of signal handler use to work around this problem. They're not stopping the use of signal handlers in general. Hotspot continues to use signals for efficiency in general. See https://github.com/openjdk/jdk/blob/9059727df135dc90311bd476...
This whole thread is about SIGSEGV, and specifically their SIGSEGV handling. However, catching normal signals is not about efficiency.
Some of their exception handling is still odd: There is no reason for a program that receives SIGILL to ever attempt continuing. But others is fine, like catching SIGFPE to just forward an exception to the calling code.
(Sure, you could construct an argument to say that this is for efficiency if you considered the alternative to be implementing floating point in software so that all exceptions exist in user-space, but hardware floating point is the norm and such alternative would be wholly unreasonable.)
> The wonderful thing about choosing not to care about facts is having whatever opinions you want.
I appreciate the irony of you making such statement, proudly thinking that your opinion equals fact, and therefore any other opinion is not.
This discussion is nothing but subjective opinion vs. subjective opinion. Facts are (hopefully, as I can only speak for myself) inputs to both our opinions, but no opinion about "good" or "bad", "nasty" or not can ever be objective. Objective code quality does not exist.

The Return of the Frame Pointers
I remember talking to Brendan about the PreserveFramePointer patch during my first months at Netflix in 2015. As of JDK 21, unfortunately it is no longer a general purpose solution for the JVM, because it prevents a fast path being taken for stack thawing for virtual threads: https://github.com/openjdk/jdk/blob/d32ce65781c1d7815a69ceac...

C++23: Removing garbage collection support
C++ lets you write anything you can imagine, and the language features and standard library often facilitate that. The committee espouses the view that they want to provide many "zero [runtime] cost," abstractions. Anybody can contribute to the language, although the committee process is often slow and can be political, each release the surface area and capability of the language gets larger.
I believe Hazard Pointers are slated for C++26, and these will add a form "free later, but not quite garbage collection" to the language. There was a talk this year about using hazard pointers to implement a much faster std::shared_ptr.
It's a language with incredible depth because so many different paradigms have been implemented in it, but also has many pitfalls for new and old users because there are many different ways of solving the same problem.
I feel that in C++, more than any other language, you need to know the actual implementation under the hood to use it effectively. This means knowing not just what the language specifies, but can occaissionally require knowing what GCC or Clang generate on your particular hardware.
Many garbage collected languages are written in or have parts of their implementations in C++. See JS (https://github.com/v8/v8)and Java GC (https://github.com/openjdk/jdk/tree/36de19d4622e38b6c00644b0...)
I am not an expert on Java (or C++), so if someone knows better or can add more please correct me.
