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.

Show HN: ILLA is an Open-source alternative to Retool

Not OP but Authentication is easy, authorization is a cross-cutting concern that often requires custom code. E.g., there are people and teams, both of which can have different kinds of access to something (read/write). Sometimes teams have sub-teams. Do the sub-teams have access to the parent teams' resources and/or vice versa? Also what kind of sharing are you going to support? Do people have to have an account to view stuff shared to them or can you just send a link? There are some efforts to make custom DSLs for describing authorization policies, to avoid cross-cutting code.
Computed fields require different treatment at every level of the stack. This isn't inherently hard, but it is an extra feature these low-code/no-code platforms need. Where things get difficult is inn migrations. It's common for a field that is computed at the beginning to become customizable, or for the computation to change. When that happens, what should the value be for old columns? Computed fields also often pull data from multiple other tables, which may require some combination of custom queries and database optimization.

Oso and OpenFGA are two alternatives that implement Zanzibar-style authorisation.

Is Datalog a good language for authorization?
4 projects | news.ycombinator.com | 19 Feb 2022
Well this was fun to see! I'm the CTO of Oso, where we're building Polar (the second of the links mentioned https://docs.osohq.com/).
I have a few really minor nitpicks, so will try and make up for it by adding to the discussion :)
First of all, it doesn't really make sense to talk about Datalog as a good language for authorization, because much like with Prolog there doesn't really exist a single implementation of it. OPA's language Rego is a datalog variant, and Polar started out as a Prolog variant (although it's not really recognisable as one any more).
And that's an important point because otherwise it would be pretty reasonable to decide that: logic programming is good for authorization => you should go find the most battle-tested language out there and use that. For example, there's SWI Prolog  and Scryer Prolog  as two of my favourites.
To me, the thing that is mind-blowing about logic programming, is (a) how powerful the paradigm is, and (b) how concisely you can implement a logic programming language. Take miniKanren  which is a full-blown logic language in a few hundred lines of code.
In my mind, the original article makes a decent case that logic programming is a good fit for authorization. And just generally I love anyone bringing attention to that :)
But to me, the reason logic programming is such a solid foundation for authorization logic is the pieces you can build on top of it. For Polar, we've added:
- Types! So you can write authorization logic over your data types and help structure your logic. We've implemented this by simply adding an additional operator into the language that can check types

First time hearing about rhai, but there's a project in that space called Oso that's authored in Rust and uses a different DSL than Rego. You may or may not find it appealing.

Authentication is probably the aspect of it that's the weakest. Authorization has a few nice libs, with Oso probably being the nicest, but authentication is mostly roll your own from what I've seen.

Why Authorization Is Hard
9 projects | news.ycombinator.com | 15 Sep 2021
Hey, Oso engineer here. Good question.
The rust core is indeed called from the ruby library (as it is with all of our 5 other host libraries). The core itself is pretty complex (there's a whole parser/interpreter in there), so maintaining it in a bunch of languages would be a bit hectic.
There are some files inside `lib/oso/polar/ffi` that define the C bindings used by the rest of the library. Here's an example: https://github.com/osohq/oso/blob/main/languages/ruby/lib/os...
We use the ffi gem to make that work: https://github.com/ffi/ffi
OPA (Open Policy Agent)
Securing CI/CD Images with Cosign and OPA
4 projects | dev.to | 15 Nov 2023
In essence, container image signing involves adding a digital stamp to an image, affirming its authenticity. This digital assurance guarantees that the image is unchanged from creation to deployment. In this blog, I'll explain how to sign container images for Kubernetes using Cosign and the Open Policy Agent. I will also share a tutorial that demonstrates these concepts.

CIAM vs. IAM: What's the difference (2022)
2 projects | news.ycombinator.com | 11 May 2023
CIAM is not nearly as popular of a term as it needs to be. When most developers build apps today, they still look at their cloud provider's IAM or Active Directory for inspiration in design of their customer-facing systems. I think this article is actually understating the complexity. Conway's Law rules all and sometimes your systems and users won't even necessarily be in your control. I urge folks to look into policy engines like OPA and ReBAC systems like SpiceDB rather than reinventing the wrong wheel.
You Broke Reddit: The Pi-Day Outage
3 projects | /r/RedditEng | 21 Mar 2023
At this point, someone spotted that we were getting a lot of timeouts in the API server logs for write operations. But not specifically on the writes themselves. Rather, it was timeouts calling the admission controllers on the cluster. Reddit utilizes several different admission controller webhooks. On this cluster in particular, the only admission controller we use that’s generalized to watch all resources is Open Policy Agent (OPA). Since it was down anyway, we took this opportunity to delete its webhook configurations. The timeouts disappeared instantly… But the cluster didn’t recover.
