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.

Migrating a Spring Boot application to Quarkus
Using the Async Profiler we were able to build flamegraphs for the first and second queries to picture the differences in path length of the two transactions execution.

Making Code Faster
> The other two languages I’ve used mostly in recent decades are Java and Ruby and the profiler situation is for both those languages is kind of shitty. I had to pay real money to get the Java profiler I used at AWS and while it worked, it was klunky, not fun to use.
These days, async profiler (https://github.com/jvm-profiling-tools/async-profiler) is much better than the Go tooling for performance. It is a joy to use and features a top-like view for the hottest methods. It works for locks, allocations and CPU time. It also integrates with JMH.

Why would a Java prime sieve run at only half its speed _some_ of the times?
Also, running it under a profiler (I recommend async-profiler[1]) should give you a good idea of where the slowdown occurs which might help you pin it down further.

Is there a way to know if my java game is slow on other computers?
Profile it. async-profiler is really great. Alternatively you can check out VisualVM/JProfiler/YourKit

async-profiler is really great at analyzing allocations, give it a shot!

Ask Java: what are some JFR-based tools that you enjoy?
JFR to Flame Graph Converter
-
Utility script for generating flamegraphs from JFR logs without dependencies.
Async Profiler converter tool does support JFR to Flame Graph, JFR to FlameScope, collapsed stacks to Flame Graph -https://github.com/jvm-profiling-tools/async-profiler#download

Launch HN: Odigos (YC W23) – Instant distributed tracing for Kubernetes clusters
We are actually able to handle the long tail of tracing by leveraging the amazing open source community. For languages like Java we use the automatic instrumentation created by the OpenTelemetry community which is really great and support ton of libraries, you can see a list of supported libraries here: https://github.com/open-telemetry/opentelemetry-java-instrum...

End-to-end tracing with OpenTelemetry
As in Python, it creates spans for every method call and HTTP entry point. It also instruments JDBC calls, but we have a Reactive stack and thus use R2DBC. For the record, a GitHub issue is open for adding support.

Implementing Distributed Tracing in a Java application
Download the latest version of the Java JAR agent, and copy jar agent file in your application code. We have placed the agent under the folder named agents.

Best performance monitoring tools?
OpenTelemetry and Java Flight Recorder (JFR) cover most bases. Use the OpenTelemetry Java agent if you want auto-instrumentation or just the APIs if you want to do your own instrumentation.

Everything you need to know about OpenTelemetry Java auto-instrumentation 👨🏽💻
OpenTelemetry provides three repositories to instrument applications. The opentelemetry-java-instrumentation repo contains the code for auto-instrumentation of Java applications.
What are some alternatives?
container-jfr - Secure JDK Flight Recorder management for containerized JVMs
spring-petclinic - A sample Spring-based application
junit-jfr - a JUnit 5 extension that generates JFR events
signoz - SigNoz is an open-source observability platform native to OpenTelemetry with logs, traces and metrics in a single application. An open-source alternative to DataDog, NewRelic, etc. 🔥 🖥. 👉 Open source Application Performance Monitoring (APM) & Observability tool
