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.

What I don't do is look at flour, water and salt, then map them all through an anonymous function, which gives me unstirred dough while leaving the original ingredients unchanged.

What is the longterm status of -XLinearTypes ?
Thanks for your interest in linear types. The sort of overarching answer is that the Covid crisis has put a serious wrench in our plans. There has been very little progress on the implementation in the past 2 years, I'm afraid. I hope to slowly pick up the pace again this year. But I make no promise as to specific plans just yet. When we have more visibility, we will publish a roadmap. This is not to say that nothing has happened at all: linear-base is getting a pretty significant release any day now, David Feuer (no affiliated with Tweag) has created linear-generics, an implementation of Generic which is compatible with linear types (there is a surprisingly subtle issue with Generic1, in particular, that I don't understand very well, so won't try to explain), we co-wrote two academic articles as well.

Does Haskell allow pure functions to use *encapsulated* impurity
See here for a linear quicksort implementation.

Monthly Hask Anything (March 2021)
Handle is defined in terms of UnsafeResource (in linear-base). This is where the linearity checking "stops". If you pattern match an UnsafeResource then you have to make sure that you correctly close/free it. Luckily, this only has to be implemented once in an internal module and is not exported in the public interface.

Tweag - linear-base makes writing Linear Haskell easy and fun
The optics sublibrary is not very developed yet. Because our arrays, which are one of the principal use-case, require a special kind of lens which we haven't managed to produce without too much code duplication yet. The design space is discussed in this issue.

Monthly Hask Anything (January 2021)
So to write a function f :: a %1 -> () you have to traverse the whole datatype a, see the Data.Unrestricted.Internal.Consumable and Data.Unrestricted.Internal.Instances, which introduces a type class consumable which implements exactly this functionality.

Ephemeral Purely Functional Data Structure And
Trying to run empty Ur shouldn't typecheck, because the Ur constructor is not linear. This seems to be an idiom used in other places of linear-base.

Supabase – General Availability Week
hey hn, supabase ceo her
we just announced GA, after ~4 years of beta. for those who don't know: supabase is a postgres hosting company. we also host other open source "backend" tools that make it easy to get started with postgres (tools like PostgREST for auto-generate APIs [0])
we owe a lot to the HN community. you launched us 4 years ago [1], when we were just a few developers. since then HN has been a staple in our journey, one of the best sources of product feedback [2]
the GA badge is mostly to signify organizational readiness. we're at a stage where we can take any profile of customer. we have a support team that works 24/7, and a success team that will help customers improve their postgres usage. we released our Index Advisor [3] yesterday, and we'll be releasing a few more products this week that helps customer with performance and security.
on a personal note: i read HN most days, and love going through the ShowHN's to see what devs are building. thanks for being an awesome community and my favorite place to lurk on the internet. i'll stick around to answer any questions

The Many Ways Not to Build an API
If you use PostgreSQL and are proficient with using its row-level security feature, you can choose from several tools/services built above RLS, including Supabase, PostgREST, and PostGraphile. They all provide a way to expose database CRUD as a web API, assuming you've configured the RLS rules to properly secure the access.

Single Software Developer Projects
SupaBase is entirely based upon PostgREST. In fact, PostgREST is arguably 49% of their value proposition according to their own website. The other 49% is PostgreSQL. PostgreSQL of course is a super mature database, and some would argue the best RDBMS on the planet, so let's ignore that part for a moment, and consider it a mature thing and move on to PostgREST.

Use PostgREST and HTMX to Build RESTful APIs from PostgreSQL Databases
PostgREST is a standalone web server that turns your PostgreSQL database into a RESTful API using the database's structural constraints and permissions to define the API's endpoints and operations. In this tutorial, you will create a simple note-taking app by leveraging PostgREST to construct a RESTful API for the app and using htmx to deliver HTML content.

We built our customer data warehouse all on Postgres
You might find some info in the docs of PostgREST [1] or in the previous discussions on HN about it [2].
For the versioning, I just have a git repo where I keep every role, schema, table, view, function, trigger, etc. definitions. Every time I change something in the database I first change it in the git repo too to have an history.
