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.

C++ Concurrency Model on x86 for Dummies
Rust does have some very cool mechanisms for safety, including in the presence of concurrency.
But this thread is generating blowback from someone saying: “slow down there with the hand-rolled atomic operations, you can hand-roll your multi-threaded locking strategy and it’ll be way safer at a modest cost!”
So, probably not the target audience for Rust ;)
I use a lot of C++ still because there are libraries I want and I have a significant investment in existing code, but I’d love to get to something more modern.
Hand-rolled atomics and load/store relaxation in application code make even seasoned C++ hackers a bit nervous: we saw this shit from business logic hackers at FB all the time and my colleague coined the term “aggressively intermediate” for the style.
I don’t mean to pick on the author of a quite good library (and it is quite good), but I ran across this the other day:
https://github.com/jupp0r/prometheus-cpp/blob/master/core/sr...
It’s correct (I think, very easy to be wrong about this sort of thing), but what are we measuring here where we can’t delegate that CAS into pthread? Branch mispredictions?
Either threads are fighting over whatever cache line that’s on (exclusive -> invalid -> exclusive -> invalid), or not. If they are, I’ve just deprived the scheduler of the opportunity to wake me up when the other 59 threads are done. If they’re not, I’ve maybe saved like one line in my L1.
And in something like a metrics library, you could be wrong for a very long time before someone pinned it down.

Dashboard for my C++ application
Grafana and Prometheus is what I’d use if you’re deploying this in Kubernetes. I haven’t used the C++ library, but generally you can just add a Prometheus client library (e.g. https://github.com/jupp0r/prometheus-cpp ) which makes it quite easy to instrument your application and expose metrics via HTTP. Then you need to configure Prometheus to scrape metrics from your application.

Docker Log Observability: Analyzing Container Logs in HashiCorp Nomad with Vector, Loki, and Grafana
Monitoring application logs is a crucial aspect of the software development and deployment lifecycle. In this post, we'll delve into the process of observing logs generated by Docker container applications operating within HashiCorp Nomad. With the aid of Grafana, Vector, and Loki, we'll explore effective strategies for log analysis and visualization, enhancing visibility and troubleshooting capabilities within your Nomad environment.

Reverse engineering the Grafana API to get the data from a dashboard
Yes I'm aware that Grafana is open source but the method I used to find the API endpoints is far quicker than digging through hundreds of files in a codebase I'm not familiar with.

Building an Observability Stack with Docker
So, you will add one last container to allow us to visualize this data: Grafana, an open-source analytics and visualization platform that allows us to see traces and metrics simply. You can set Grafana to read data from both Tempo and Prometheus by setting them as datastores with the following grafana.datasource.yaml config file:
