Handle Incoming Webhooks with LiteJob for Ruby on Rails
Firstly, LiteJob's reliance on SQLite inherently restricts its horizontal scaling capabilities. Unlike other databases, SQLite is designed for single-machine use, making it challenging to distribute workload across multiple servers. This can certainly be done using novel technologies like LiteFS, but it is far from intuitive.

Experimenting on the Edge with Turso (and Go)
Im curious to know if others have tried out Turso or LiteFS or any of the newer edge db providers that are popping up in 'real world' applications and what your experiences have been?

Skip the API, Ship Your Database
Author here. I think we could have set better expectations with our Postgres docs. It wasn't meant to be a managed service but rather some tooling to help streamline setting up a database and replicas. I'm sorry about the troubles you've had and that it's come off as us being disingenuous. We blog about things that we're working on and find interesting. It's not meant say that we've figured everything out but rather this is what we've tried.
As for this post, it's not managed SQLite but rather an open source project called LiteFS [1]. You can run it anywhere that runs Linux. We use it in few places in our infrastructure and found that sharing the underlying database for internal tooling was really helpful for that use case.

SQLedge: Replicate Postgres to SQLite on the Edge
#. SQLite WAL mode
From https://www.sqlite.org/isolation.html https://news.ycombinator.com/item?id=32247085 :
> [sqlite] WAL mode permits simultaneous readers and writers. It can do this because changes do not overwrite the original database file, but rather go into the separate write-ahead log file. That means that readers can continue to read the old, original, unaltered content from the original database file at the same time that the writer is appending to the write-ahead log

#. dolthub/dolt: https://github.com/dolthub/dolt
> Dolt can be set up as a replica of your existing MySQL or MariaDB database using standard MySQL binlog replication. Every write becomes a Dolt commit. This is a great way to get the version control benefits of Dolt and keep an existing MySQL or MariaDB database.
#. pganalyze/libpg_query: https://github.com/pganalyze/libpg_query :
> C library for accessing the PostgreSQL parser outside of the server environment
#. Ibis + Substrait [ + DuckDB ]
> ibis strives to provide a consistent interface for interacting with a multitude of different analytical execution engines, most of which (but not all) speak some dialect of SQL.
> Today, Ibis accomplishes this with a lot of help from `sqlalchemy` and `sqlglot` to handle differences in dialect, or we interact directly with available Python bindings (for instance with the pandas, datafusion, and polars backends).
> [...] `Substrait` is a new cross-language serialization format for communicating (among other things) query plans. It's still in its early days, but there is already nascent support for Substrait in Apache Arrow, DuckDB, and Velox.
#. benbjohnson/postlite: https://github.com/benbjohnson/postlite
> postlite is a network proxy to allow access to remote SQLite databases over the Postgres wire protocol. This allows GUI tools to be used on remote SQLite databases which can make administration easier.
> The proxy works by translating Postgres frontend wire messages into SQLite transactions and converting results back into Postgres response wire messages. Many Postgres clients also inspect the pg_catalog to determine system information so Postlite mirrors this catalog by using an attached in-memory database with virtual tables. The proxy also performs minor rewriting on these system queries to convert them to usable SQLite syntax.
> Note: This software is in alpha. Please report bugs. Postlite doesn't alter your database unless you issue INSERT, UPDATE, DELETE commands so it's probably safe. If anything, the Postlite process may die but it shouldn't affect your database.

LiteFS Cloud: Distributed SQLite with Managed Backups
LiteFS works sorta like that. It provides read replicas on all your application servers so you can use it just like vanilla SQLite for queries.
Write transactions have to occur on the primary node but that's mostly because of latency. SQLite operates in serializable isolation so it only allows one transaction at a time. If you wanted to have all nodes write then you'd need to acquire a lock on one node and then update it and then release the lock. We actually allow this on LiteFS using something called "write forwarding" but it's pretty slow so I wouldn't suggest it for regular use.
We're adding an optional a query API over HTTP [1] soon as well. It's inspired by Turso's approach. That'll let you issue one or more queries in a batch over HTTP and they'll be run in a single transaction.

Basically, LiteFS: https://github.com/superfly/litefs

Key-value store has been added to Deno API
But my guess is they'll have an alternate implementation or something like LiteFS in Deno Deploy that will make this substantially more interesting when running in the Cloud.

Lots of things don't need failover, but if you do, you can use Bedrock, which is built on sqlite.

Ask HN: Hunting for a Framework
Vapor[0] based on Swift. Advantage of this is that you don't have to evaluate multiple frameworks for Swift and suffer paralysis by analysis. All the Swift community is behind one framework.
The next is Actix[1] based on Rust. There are many frameworks in Rust and most of them have not reached 1.0 And which framework will survive becomes a question.
Other not so well-known is Wt[2] based on C++. This actually is created for programmers who are not web developers. The development experience is similar to desktop app development like Qt.
If that is not acceptable then Django[3], based on Python, is the one that will be good for you.
For the front-end I would recommend Flutter[4]. As much as I dislike getting tied to a single company for whom the framework is not their bread-and-butter, I don't see any other viable options to Flutter that will cover all web, mobile and desktop out of the box.
For databases, I would recommend BedrockDB[5], if you are not averse to SQLite. Or FoundationDB[6], if you want NoSQL. But if you are not concerned about horizontal scalability or okay with self-managing database availability, then PostgreSQL[7] is a very good option.
For push notifications, PushPin[8] is a good option.
