uptime
CouchDB
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: Have you used SQLite as a primary database?
When I maintained uptime.openacs.org (https://gitlab.com/siddfinch/uptime) and MyTurl (both running AOLserver) I wrote internal versions for a place I was working at.
I switched from Postgres to SQLite for a couple of versions, put mainly because Postgres wasn't "supported" I called SQLite an "internal database thing".
Worked flawlessly for about 7-8 years before both services were gobbled up into micro API services.
At the last count, we have about 14,000 services checked by uptime (about 1,000 every 5 minutes, 2,000 every 10 minutes, the rest every 15). Probably had about 60,000 tinyurls in MyTurl. We also ran the MyTurl urls through uptime every night to look for bad links. The system go hammered, often.
It took minor tweaking to get the the best performance out of the database and AOLserver has some nice caching features, which helped to take the load off the database a bit. But overall, it worked as well as the Postgres counterpart.
And now, I have to figure out why I never released the SQLite version of both.

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.

I just turns out you can't always do that in a real codebase. For example see here:
