    Project mention: Ask HN: Any Comprehensive Courses on Auth? | | 2023-11-19

    FastAPI's tutorial on how to implement a basic OAuth server helped me a lot in understanding the basic concepts.

    After getting familiar, I self hosted Keycloak and integrated it with my FastAPI server.

  • sirix

    SirixDB is an an embeddable, bitemporal, append-only database system and event store, storing immutable lightweight snapshots. It keeps the full history of each resource. Every commit stores a space-efficient snapshot through structural sharing. It is log-structured and never overwrites data. SirixDB uses a novel page-level versioning approach.

    Project mention: Endatabas: A SQLite-inspired, SQL document database with full history | | 2023-12-01

    I'm working on something similar for the JVM, however with no document semantics, but on a much more fine granular level.

    JSON is shredded during an initial import into a tree structure with fine granular nodes. Thus, an import can be done with very low memory consumption (permitted that auto-commit issues a sync to disk before RAM space is exceeded). Furthermore, it doesn't require a WAL for consistency. Instead the indexes are stored in a log-structure using a persistent tree (as in every commit creates a new tree root). A sliding snapshot algorithm makes sure, that only a fragment of a page has to be copied on a write.

    As thus, it's also a perfect candidate for an event store, storing both the (lightweight) snapshots and tracking the changes optionally.

    The architecture is described over here:

    Furthermore I'm working on a tutorial for a local client usage (work in progress):

    Kind regards

  • keycloak-config-cli

    Import YAML/JSON-formatted configuration files into Keycloak - Configuration as Code for Keycloak.

    Project mention: Beyond the login page | | 2023-11-29

    Most of the time nowadays, I prefer offloading this to an identity provider, using OpenID Connect or soon Federated Credential Management (FedCM), even if that means shipping an identity provider as part of the deliverables (I generally go with Keycloak, with keycloak-config-cli to provision its configuration). I'm obviously biased though as I work in IT services, developping software mainly for intranets/extranets, and companies now increasingly have their own identity providers or at a minimum have that in their roadmap. So YMMV.
