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.

Example of Entity Component System in Go
Good question, I think there's many different lessons. To your point about bitmasks, you can imagine that each component (i.e. column) has an array of data and a large bitmap that identifies whether a component is present or not. Had to build a SIMD implementation so you can do and, and not, or and xor operations on millions of components within reasonable amount of time. Interestingly enough, you still need a hashmap or b+tree in case you want to retrieve a component by it's ID instead of an index, but the rest of things can be modeled with bitmap indexes.

Ask HN: Hosting on Digital Ocean, any advice for monitoring and deployments?
If your app is instrumented with OpenTelemetry, I'd really recommend something like SigNoz (https://signoz.io/) or Axum (https://axiom.co/) (or even Baselime.io but their application is a mess to work with)
1. Axiom has a generous free plan (not sure if it's self-hostable)

How our infrastructure supports last-minute studying
Great choice of monitoring and analytics tools (Sentry, Axiom, Posthog and Uptime Kuma) coupled with amazing Slack integrations that allowed us to iron out any issues way before the traffic spike while the troubling features were still fresh from the oven.

How single message broke all our monitoring and dashboards
For the last 1.5 years, I have been using Axiom for all of my logs ingestion, querying, and monitoring needs. It is a great product and I never had one issue with it in my time using it. Spoiler alert, even today, when it failed it was actually my fault, but let's see what happened.

How To Collect Temporal.io Logs Using Axiom And Pino
Axiom is an observability backend with OpenTelemetry support. I chose it for my recent project because of its cost, especially for hobby projects or serious projects in its early phase. They provide a JavaScript library that you can use as transport for pino.
