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.

Seeing through hardware counters: a journey to threefold performance increase
Would an atomic mutable subclass cache (not sure what it's used for, downcasting?) be unnecessary in a language built around static rather than dynamic dispatch by default, like C/C++/Rust and perhaps Go? Or would it still speed up dynamically dispatched code, but is less practical or worthwhile so it isn't used in practice? (Though Rust's Arc also suffers from atomic contention similar to this blog post, when used across dozens of threads: https://pkolaczk.github.io/server-slower-than-a-laptop/)
Also it's somewhat ironic that the JVM source code (https://github.com/openjdk/jdk8u/blob/jdk8u352-b07/hotspot/s...) says "This code is rarely used, so simplicity is a virtue here" at the site of a bottleneck.

Minecraft 1.8.9 Consistently Crashes after 5 Mins
Use the latest JDK (Developer's Kit) or JRE (Runtime Environment) for Java 8, compiled and distributed by AdoptOpenJDK from the official Read-Only source.

How are LTS updates made?
The majority of the work on 8u, 11u, 17u releases happens in OpenJDK upstream, in so called JDK Updates Projects, by engineers from the interested JDK vendors. You can get a peek who does this kind of work from the repository histories, for example the most recent 11.0.13 is done by engineers from Red Hat (including yours truly), SAP, Azul, Microsoft, BellSoft, Tencent, Amazon, Alibaba, IBM, ARM, Google.

Log4Shell Log4j vulnerability (CVE-2021-44228) – cheat-sheet reference guide
> whatever it returned would just get inserted as a string into the log output, no big deal.
Once you can inject anything that gets resolved, you have an information disclosure vulnerability unrelated to the RCE.
If I can just DNS resolve any ${env} variable from the JVM, a lot of systems are compromised by just exposing the env or system variables configured for runtime.
Just getting your $AWS_ACCESS_KEY_ID and $AWS_SECRET_ACCESS_KEY env vars can compromise your bucket (sure, that is a really unsafe setup now, but it was almost the standard a few years ago over configuring it explicitly).
So a logging system which will merely resolve a hostname derived from a variable was bad enough to compromise many systems.
The serialization loophole was fixed in a jdk8 update.
https://github.com/openjdk/jdk8u/commit/006e84fc77a582552e71...
But even with that in place, the information disclosure of java System or env properties is bad enough to break actual systems in prod.

Log4j RCE Found
> Turns out, by including "." in some part of the URL to this remote class, Log4j lets off its guard & simply looks up to that server and dynamically loads the class file.
No it doesn't. That was disabled by default in 2009, and was disabled by default in every release of Java 8 or later: https://github.com/openjdk/jdk8u/commit/006e84fc77a582552e71...
Unless i am mistaken, i don't believe the attack as described by LunaSec actually works against a default-configured JVM released any time in the last decade.

An Overview of Kubernetes Security Projects at KubeCon Europe 2023
Syft is a popular open source CLI tool created by Anchore for generating an SBOM from container images and filesystems. It’s designed to provide a catalog of dependencies for other tools to use as a data source. It supports many popular programming languages, package managers, and container image formats.

Launch HN: EdgeBit (YC W23) – live software vulnerability analysis
Inside of the SBOMs, we can detect a lot: https://github.com/anchore/syft#supported-ecosystems
You're right that the active/dormant detection needs to be customized per type of runtime. We cover rpm/deb, python and java with the node and others coming very soon. The compiled languages will be our main focus next. For example, Go binaries embed some dependency metadata in the binary itself.
Also related to this effort is the "in-toto" integrity chain: https://in-toto.io/in-toto/ Since we're already connecting build to run, we aim to complete the chain.

12 Things You Might Not Know About Buildpacks
A Software-Bill-of-Materials (SBOM) lists all the software components included in an image. Buildpacks support SBOMs in CycloneDX, Syft and SPDX formats.

`cargo audit` can now scan compiled binaries
I think you can already do that using Syft.

Wake-up call: why it's urgent to deal with your hardcoded credentials
Today corporations, open source projects, nonprofit foundations, and even governments are all trying to figure out how to improve the global software supply chain security. While these efforts are more than welcome, for the moment, there is hardly any straightforward way for organizations to improve on that front.

3 ways to improve your OSS project's resilience for Hacktoberfest
Syft is a popular open source tool that generates SBOMs for software applications and also containers. You can execute it manually and include the generated artifacts into your release, but you can also automate the process using a GitHub Action that will be triggered whenever you have a new release on your repository.
