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.

Announcing: Stargate 1.0 GA; REST, GraphQL, & Schemaless JSON for Your Cassandra Development
DataStax built Stargate into Astra to give us, app developers, a natural data API stack which meshes with the Jamstack (or serverless stack of your choice). Stargate in Astra is built on the rock solid NoSQL data engine (Apache Cassandra) which powers Netflix, Instagram, Yelp, iCloud and other apps we all use everyday.

How the world caught up with Apache Cassandra
Twelve-plus years after its invention, Cassandra is now used by approximately 90 percent of the Fortune 100, and it’s appeal is broadening quickly, driven by a rush to harness today’s “data deluge” with apps that are globally distributed and always-on. Add to this recent advances in the Cassandra ecosystem such as Stargate, K8ssandra, and cloud services like Astra DB, and the cost and complexity barriers to using Cassandra are fading into the past. So while it’s fair to say that while Cassandra might have been ahead of its time in 2007, it’s primed and ready for the data demands of the 2020s and beyond.

How to use Aggregate Functions in Stargate’s GraphQL API
Until now, aggregate functions were only available using cqlsh (the CQL Shell). However, with the Stargate 1.0.25 release, they are now also available using the GraphQL API. In this blog entry, I’ll walk you through the process to get early access to this exciting new functionality in Stargate, and how to set up everything you need to test your own aggregate queries.

Deploy a Netflix Clone with GraphQL and DataStax Astra DB
Stargate is an open-source data gateway that makes it simple to query any Cassandra database using GraphQL types, queries, and mutations. When you add the Stargate GraphQL API to a Cassandra deployment, it scans the database and automatically creates HTTP endpoints with GraphQL queries and mutations for the objects it finds.

How to Build and Deploy a Serverless Game with DataStax Astra DB, JAMStack, Stargate, and Netlify
BattleStax is implemented as a JAMStack app that uses Stargate, Netlify, DataStax Astra DB, and GitHub to demonstrate how to build and deploy an application using modern, scalable architectures. In this post, we’ll break down the video to help you quickly create your own BattleStax game using React and Redux — implemented with a CI/CD pipeline, global content delivery network (CDN), and Apache Cassandra®.

Build a crypto application with GraphQL Federation
The second best part is that once you have your hands on Astra DB, you automatically get access to Stargate — an open-source data gateway that makes it easy to query any Cassandra database through REST APIs. One such API is the Stargate GraphQL API, which allows you to do the following:

How to Create a Fullstack App Using NuxtJS, NestJS, and Datastax Astra DB (with a Little Help from Github Copilot)
Astra DB uses Stargate APIs so you can interact with data using GraphQL, CassandraQL, REST, or Document API.
-
Data Modeling in Cassandra and Astra DB
Stargate is an open-source data gateway deployed between applications and a database. It supports different API options for an application to interact with Cassandra, Astra DB, and K8ssandra. Stargate’s API extensions include CQL, REST, GraphQL, and Document APIs.

Stargate gRPC: The Better Way to CQL
Recently, we released gRPC as the newest API supported by Stargate, our API data gateway. On the surface, it would seem like the API doesn’t do very much; it receives CQL queries via the gRPC protocol, then passes those to Apache Cassandra® and returns the results. Sounds like a pretty modest feature release, right?

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:

Teach Yourself Programming in Ten Years (1998)
I completely agree but do feel it needs qualifying. The problems beginners run into aren't usually the same as the problems experienced devs run into when adopting a language new to them, but where I see the two overlap I know something is a serious hazard in a language.
Java as a first language: won't like the boilerplate but won't have any point of comparison anyway, will get a few NPEs, might use threads and get data races but won't experience memory unsafety.
Go as a first language: much less boilerplate, but will still get nil panics, will be encouraged to use goroutines because every tutorial shows off how "easy" they are, will get data races with full blown memory unsafety immediately.
Rust as a first language: `None` // no examples found
I think Go as a beginner language would be better if people were discouraged from using goroutines instead of actively encouraged (the myth of "CSP solves everything"), otherwise I think it needs much better tooling to save people from walking off a cliff with their goroutines. And no, -race clearly isn't it, especially not for a beginner.
And in one respect I've found Go more of a hazard for experienced devs than beginners: the function signature of append() gives you the intuition of a functional programming append that never modifies the original slice. This has literally resulted in CVEs[1] even by experienced devs, especially combined with goroutines. Beginners won't have an intuition for this and will hopefully check the documentation instead of assuming.

Start your server remotely
I build the Tasmota firmware for the S31's nightly, and expose the Prometheus endpoint so I can also monitor the current used by these devices in real time with the data pushed to Grafana. I have ~30 of them in my home/homelab, and servers, appliances, sump pump, fans, etc. are all monitored by my S31 fleet.
