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.

Ask HN: When is pure functional programming beneficial?
... or working in an environment or on a problem for which functional patterns apply.
Suppose you are writing a "CRUD" app that writes to a relational database, how do you apply functional programming to that? The whole point of an application like that is that it makes side effects.
In some cases you can break those problems down into functional pieces. Consider Python drivers for a product like
One major problem is that you want drivers that work synchronously and asynchronously, the structure of the average api call is something like

Graph Databases vs Relational Databases: What and why?
First, you need to choose a specific graph database platform to work with, such as Neo4j, OrientDB, JanusGraph, Arangodb or Amazon Neptune. Once you have selected a platform, you can then start working with graph data using the platform's query language.

PRQL a simple, powerful, pipelined SQL replacement
Some databases like ArangoDB (https://www.arangodb.com/) allow you to use Javascript instead of SQL.
However, using a type-unsafe, turing-complete language introduces type unsafety and turing-complete problems to the query layer; the usual problems we know and love, such as infinite loops, runtime type errors, exceptions, and the like.
Personally, I'm looking forward to a WASM runtime for databases -- so we can run webassembly on the database. This COULD be carefully designed to be statically checked and, possibly, make it really hard to write runaway loops.

Ask HN: Why are we so fragmented in databases options?
Personally my favorite db for pet projects is
I think you hear very little about it because ADB users see it as a "secret weapon" to crush their competitors with. I've done large ontology work (MESH and other health ontologies) and IoT work (keep several years of sensor readings for sensors in my house) and workflow systems (select interesting HN articles or jobs I want to apply to) and it has never let me down. I haven't run a real instance serving customers in the cloud though.
For the last few years every eng manager I have worked with has been a fan of
In the early 2000s I thought it overpromised and underdelivered and called it CrashGreSlow but after MySQL got bought by Oracle the pgsql team has worked hard to improve it I think it is great today. It supports all kinds of advanced features such as stored procs, full-text search, JSON equivalent fields, etc.

System Design: The complete course
For mutual friends, we can build a social graph for every user. Each node in the graph will represent a user and a directional edge will represent followers and followees. After that, we can traverse the followers of a user to find and suggest a mutual friend. This would require a graph database such as Neo4j and ArangoDB.

Using graphQL+gRPC+Golang to Create a Bike Rental Microservices, with persistence on ArangoDB.
This a NOSQL database built for high availability and high scalability, a perfect fit for implementing persistence in microservices. ArangoDB is an open source native multi-model database that supports graph, document and key-value data models allowing users to freely combine all data models in a single query. Dive deeper into this database and its features here.

Which database would be a great choice for our game?
Finally, while it is not in the GCP stack, there is a pretty cool graph database https://www.arangodb.com/ . You can use their Oasis and deploy into GCP though. Still, if you were to model a lot of relations between all your trivia information, then a graph database like this could unlock some interesting possibilities.

Building a GraphQL API on AWS with Amazon Neptune Graph Database and CDK
As an AWS person, I became really interested in how I may take advantage of a an AppSync GraphQL API backed by a graph database. There are many great options to choose from, including things like Neo4j and ArangoDB which I hope to also try out sometime soon, but for this build I chose to use Amazon Neptune.

How to run WebAssembly from your Rust Program
Apache CouchDB belongs to the family of NoSQL databases. It is a document store with a strong focus on replication and reliability. One of the most significant differences between CouchDB and a relational database (besides the absence of tables and schemas) is how you query data. Relational databases allow their users to execute arbitrary and dynamic queries via SQL. Each SQL query may look completely different than the previous one. These dynamic aspects are significant for use cases where you work exploratively with your dataset but don't matter as much in a web context. Additionally, defining an index for a specific table is optional. Most developers will define indices to boost performance, but the database does not require it.

Erlang: The coding language that finance forgot
I just turns out you can't always do that in a real codebase. For example see here:

Alternative to MongoDB?
I've heard people recommend CouchDB, no personal expience though. It is also nosql, somewhat similar to mongo. The selling feature is easy scalability. I'm planning to take a weekend to try it out myself. https://couchdb.apache.org/
