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.

Bridging the Blockchain / Database Divide (Temporal Graph Queries for Corda)
Hi, a couple of my colleagues spent some time working on this integration with our open source database product (https://opencrux.com), and I'm curious to know - has anyone done similar things to connect Corda with a secondary off-the-shelf query engine?

Looking for Intermediate & Advanced SQL Users for Research
The context is that I work on on https://opencrux.com, which offers a bi-temporal Datalog query layer (as well as SQL) that more or less addresses the intersection of the two, since Datalog is great for expressing recursive queries.

How to query Datomic, Datascript, Asami, or other graph databases
I suppose another somewhat important distinction, once again performance related, is that graph databases will typically track index statistics to aid with query planning. For example, Crux uses stored knowledge of attribute-value cardinalities (recently via HyperLogLog) to optimise the join order of a query - this can make a big difference when attempting to traverse large graphs efficiently.

Free project to practice sql ?
Agreed, recursive querying & bitemporal modelling in SQL are non-trivial problems, and the combination of the two is harder still. For an alternative perspective on tackling such problems I'd suggest looking at Datalog, which makes recursion a breeze, and a database with first-class bitemporality - both of which feature in https://opencrux.com (which I happen to work on :))

Ask HN: What under-the-radar technology are you super excited about?
I work on Crux so can share a few details about our implementation of Datalog. The query is compiled into a kind of Worst-Case Optimal Join algorithm [0] which means that certain types of queries (e.g. cyclic graph-analytical queries, like counting triangles) are generally more efficient than what is possible with a non-WCOJ query execution strategy. However, the potency of this approach relies on the query planner calculating a good ordering of variables for the join order, and this is a hard problem in itself.
Crux is usually very competent at selecting a sensible variable ordering but when it makes a bad choice your query will take an unnecessary performance hit. The workaround for these situations is to break your query into smaller queries (since we don't wish to support any kind of hinting). Over the longer term we will be continuing to build more intelligent heuristics that make use of advanced population statistics. For instance we are about to merge a PR that uses HyperLogLog to inform attribute selectivity: https://github.com/juxt/crux/pull/1472

Filecoin Foundation Successfully Deploys IPFS in Space
> CDNs
If you think IPFS is trying to "re-spin CDNs as their invention", I'm pretty sure you misunderstand what IPFS. The homepage is a great starting point if you're curious rather than antagonistic: https://ipfs.tech/
> IPFS doesn't solve persistence of data
I don't think it claims to solve this either? What it does claim to solve is the persistence of identifiers of data.
> doesn't solve churn in p2p systems
What P2P system has ever done so or even claimed to have done so?

Build an AI-powered NFT generator with TS, GPT, Polygon and CASE (Part 1/2)
We will create a web app that will let users mint a NFT in one click: creating an AI art from a prompt, storing it on IPFS and mint the unique NFT in Polygon so you can see it on OpenSea. Pretty cool right ?

Building Trust in a Trustless World: Decentralized Applications Unveiled
IPFS, which stands for Inter-Planetary File System, is a decentralized storage system where files are distributed among peers in a peer-to-peer (P2P) network. It operates on a "content addressable" model, meaning that each file is given a unique hash that serves as its identifier. By using this hash, you can retrieve any file from any IPFS node in the network.

Mirrors or alternatives to e621 on the decentralized / distributed web
Was thinking of something and figured it would be a good opportunity to ask here. With the censorship madness going on in the world and furry community included, I often worry if even places like e621 can remain free and open in the face of increasing pressure by increasingly angry and authoritarian crowds. For both this and other geek reasons I've been interested in decentralized internet technology for a long time, following projects like IFPS which I just love as a concept.
