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.

Ada news digest April 2022
Original discussion was there, I guess you can post your comments to that PR to keep the discussion in one place.

Is Maintaining An Ada ISO Standard Worthwhile?
I forgot where I saw it, but I do recall reading somewhere that the ARG had discussed whether a shorter revision cycle would be better or not. I wouldn't be surprised if the creation of this ( https://github.com/AdaCore/ada-spark-rfcs ) was inspired by that discussion.

Brett Slatkin: Why am I building a new functional programming language?
Ada might be getting pattern matching soon too:

Why Rust?
> I did some ADA in the past and yes, it is a nice language, but it lacks the modernity and a dynamic community like Rust. ADA did received some nice update to its specification, but, just like C++, it struggle / cannot really fit the latest innovation in programming language that easily.
I'm still learning both Ada and Rust, nevertheless I humbly disagree. The more I learn it and other "old" languages the more it looks to me like "modern" ones rediscover things that have been present in other languages for years.
The really significant difference I can see for now is that Ada is not focused so strongly on functional programming paradigm. Rust borrow checker is a strong success of course and was another significant difference, but latest SPARK got borrow checking capabilities too, AFAIK.
While Ada's open-source community is smaller, I find it as energetic and devoted to improving the ecosystem as Rust's. I have no idea about closed-source community, but in the past 4 years ArianeGroup [1], Airbus [2] and Nvidia [3] talked about choosing Ada for their high-integrity applications.
> And to be fair, it is fine. ADA is very much a "committee" language (its spec are ISO/IEC) instead of a "community" language (all the spec and rfc of Rust are on github and anyone can easily discuss them).
You can discuss Ada/SPARK RFCs here: https://github.com/AdaCore/ada-spark-rfcs . I think I once saw on Ada forum or chat that someone proposing changes to the language was simply invited to talk to people working on the standard, so it doesn't look like the language is developed in isolation or something.
> This makes it so that ADA doesn't get the attention, and the rapidity of innovation, that a language like Rust does, but ADA is mostly made for program that will need to be maintained in critical operations for decades with the code being maintainable and compilable far into the future.
I think that Ada adopted quiet quickly to standards set by Rust: lower entry barrier toolchain, compelling licensing, library distribution, RFCs, etc. And in terms of language features, in many areas it's not only on par, but ahead of competition. So you're less likely to see lots of changes, but they do happen nevertheless. I'm not saying Ada is perfect, of course. There are parts of it that other languages do better. No shame in that.
IMHO, the reason Ada is unknown to many people is a combination of its past, myths surrounding it, and general trend of people to follow trends. ;) But I currently find Ada/SPARK even more compelling option than Rust, even though I like both.

Does ada support object methods?
There's a proposal to allow dot syntax for untagged types as well.

Can one use lambda calculus as an IR?
Depending on what you mean by practical it already is! https://github.com/HigherOrderCO/Kind HVM was developed to be an efficient backend for the Kind language from the same folks
