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.

Stream Updates to Your Users with LiteCable for Ruby on Rails
LiteCable is tailored for vertical scaling by a tight integration of components. If you extract maximum performance from the SQLite engine, the limits of this approach are pushed a lot further. Once you observe that your latencies start to explode, though, I would suggest researching options like AnyCable, which inherently provide better strategies for horizontal scaling.

Using Tailscale on Lambda for a Live Development Proxy
So far, everything is working great with our new LambdaCable gem. Eventually it will be a drop-in adapter for ActionCable and join the ranks of other popular alternatives like AnyCable. To bring the project to completion faster, I needed feedback loops that were much faster than deploying code to the cloud. I needed a development proxy! One where my Rails application would receive events from both Lambda's Function URLs and the WebSocket events from API Gateway. Illustrated below with a demo video.

AnyCable v1.3: embedded NATS, StatsD, and more
AnyCable v1.3 has been just released. The major highlights are:
-
Faster RuboCop runs for Rails apps
I've been using this technique for a long time for gems developmentāto speed up CI RuboCop runs (by installing only the linter dependencies). Here is my typical rubocop.gemfile:
-
Any performance/memory issue with Ruby 3.x compared to 2.7?
It does, but the precompiled binaries are only for < 3.1: https://rubygems.org/gems/grpc/versions/1.43.1-x86-linux
-
Action cable or AJAX? Performance and solution - what to choose?
Action cable is probably what you're looking for. If you start having performance issues, AnyCable is a more performatic option that requires almost no changes in your ruby code.

Kubing Rails: stressless Kubernetes deployments with Kuby
I decided to give it a try for the AnyCable demo application, which requires deploying not only a Rails app, but also additional services for AnyCable.
-
Async Ruby
I think what's being talked about here is the back end implementation for ActionCable. By default it uses ruby threads to push over open web sockets. There's at least one production quality drop in implementation (https://anycable.io/) that address the default scalability issues you'll have with ActionCable. The async support would seem to allow one to go much further with default rails before needing to move to something more performant.

Understanding AWS Lambda Proactive Initialization
AWS Serverless Hero Ken Collins maintains a very popular Rails-Lambda package. After some discussion, he added the capability to track Proactive Initializations and came to a similar conclusion - in his case after a 3-day test using Ruby with a custom runtime, 80% of initializations were proactive:

š Goodbye Cold Starts ā¤ļøHello Proactive Initialization
This means the Monitoring with CloudWatch is just half the picture. But how much is your application potentially benefiting from proactive inits? Since Lamby v5.1.0, you can now find out easily using CloudWatch Metrics. To turn metrics on, enable the config like so:

The Elusive Lambda Console; A Specification Proposal.
After years of smashing Cloud & Rails together, I've come up with an idea. Better than an idea, a working specification! One where us Rails & Lambda enthusiasts can once again "console into" our "servers" and execute CLI tasks like migrations or interact via our beloved IRB friend, the Rails console. Today, I would like to present, the Lambda Console project. An open specification proposal for any AWS Lambda runtime to adopt.

The Next Generation of Serverless Is Happening
> Does this mean you have a cron job just pinging the serverless function every 3 minutes? I'm curious how much this adds on to your costs. It means that the whole "don't pay for non-usage" thing is not quite true, but maybe it's still significantly cheaper than running an EC2 instance or whatnot. I'm curious about the cost calculation here.
Yes, specifically it kicks off a Lambda function that does a parallel GET to our website at a special endpoint that has a 100ms "wait" and basic DB call. This keeps the lambda process alive/in-memory.
To keep a function alive costs ~125ms (100ms wait + 25ms full func roundtrip). every 3 minutes. ~0.041% of 1x CPU time. Our website server costs are tiny and lower for Staging and UAT. Benefit - can scale to 1000x (AWS Limit) servers at the speed of your cold start time.
> Another thing I'm curious about, since you have a container-based deployment, did you compare with Fargate?
Yes we use Fargate for our core product which is built in Rails before containers could be deployed in Lambda. Rails works fine on Lambda[0] but the transition cost wasn't worth it for us. Fargate is great, but as you point out it is expensive if your application isn't a user heavy one like ours. To be highly available, we always have a minimum of 2 online but we're a b2b application so our night usage, 10pm-6am is zero. But I have 2 machines just sitting there. This is why i love Lambda >> Fargate.
Also, scalaing Fargate machines is slow if you get a traffic spike.

Using Tailscale on Lambda for a Live Development Proxy
If you are curious to learn more about how Rails & Lambda work together, check out our Lamby project. The architecture of Lambda Containers works so well with Rails since our framework distills everything from HTTP, Jobs, Events, & WebSocket connections down to amazing CMD Docker contract. The architecture above at the proxy layer was easy to build and connect up to our single delegate function, Lamby.cmd. Shown below.

Ruby on Rails on Lambda on Arm64/Graviton2!
Today I am happy to announce that Lamby (Simple Rails & AWS Lambda Integration using Rack) now demonstrates just how easy it is to use multi-platform arm64 images on AWS Lambda. If this sounds interesting to you, jump right into our Quick Start guide and deploy a new Rails 7 on Ruby 3.2 Ubuntu image to see it for yourself.
