The Datalog Educational System (DES) is a deductive database with Datalog, SQL, Relational Algebra, Tuple Relational Calculus and Domain Relational Calculus as query languages developed mainly for education. It can be used from most common Prolog interpreters over any supported OS and from portable executables (Windows, Linux and MacOS).

...It was built with strong respect to your privacy – you will never see ads and it does not include analytics services (or actually any services at all). You are highly encouraged to explore source code and use it in your projects. Fast non-blocking computations with web workers. No tracking, no ads, no other server connections – everything runs in browser only. Full offline support. Dark theme support. All-in-one application for everyday tasks.

Stampede is a high-performance cache stampede prevention library designed to mitigate excessive cache misses in distributed caching systems. It helps avoid the "thundering herd" problem, where multiple requests simultaneously trigger expensive computations when a cache entry expires. Stampede manages cache expiration intelligently, ensuring that only one request regenerates a missing cache entry while others wait for the updated value.

...Haxl can automatically batch multiple requests to the same data source, request data from multiple data sources concurrently, cache previous requests, and memoize computations. Having all this handled for you behind the scenes means that your data-fetching code can be much cleaner and clearer than it would otherwise be if it had to worry about optimizing data-fetching. To use Haxl in your own application, you will likely need to build one or more data sources: the thin layer between Haxl and the data that you want to fetch, be it a database, a web API, a cloud service, or whatever. ...
