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.

Migrating from SQLite to PostgreSQL
FWIW, I've used Litestream on Google Cloud Run and never run into issues, but I haven't pushed it much:

PicoShare: A minimalist, easy-to-host service for sharing images and other files
Currently, no. I've implemented that functionality recently in my other tool, LogPaste, so it shouldn't be too hard to reproduce here.

How Litestream Eliminated My Database Server for $0.03/month
My tool is called LogPaste. It allows users to generate shareable URLs for text files. I use it in my open-source KVM over IP device so that users can easily share diagnostic logs with me.

LogPaste: A self-hostable pastebin that replicates data to any S3 provider
I designed it with self-hosting in mind, so there are instructions for hosting it under Docker, as well as with several free cloud hosting providers. You can even host the data storage part yourself if you use a solution like Minio.

The Architecture of a One-Man SaaS
I still use GCP, but I avoid locking myself into their proprietary infrastructure when I'm writing new stuff. I feel like Google is far too cavalier about deprecating services and forcing their customers to do migration work.
It is hard to replace GCP's managed datastores because I really don't want to maintain my own database server (even if it's a managed service that someone else upgrades for me). So I've stuck to Google Cloud Datastore / Firestore, but I've been experimenting a lot with Litestream[0], and I think that might be my go-to choice in the future instead of proprietary managed datastores.
Litestream continuously streams data from a SQLite database to an S3 backend. It means that you can design your app to use SQLite and then sync the database to any S3 provider. I designed a simple pastebin clone on top of Litestream, and I use it in production for my open source KVM over IP. It's worked great so far, though I'm admittedly putting a pretty gentle workload on it (a handful of requests per day).

.NET 6 is now in Ubuntu 22.04
I have two DigitalOcean sites on the same VPS just serving from kestrel behind an nginx reverse proxy and then one site on a Hetzner VPS where I was playing around with k3s.
For digitalocean I followed this post which is probably way out of date now https://www.hanselman.com/blog/publishing-an-aspnet-core-web...
For the k3s site the source is here https://github.com/EliotJones/LetsShip/blob/main/kubernetes/... though worth noting I have set up LetsEncrypt incorrectly but that's my lack of k3s understanding.

We need to have a talk about making life easier for newcomers to .NET
This - https://github.com/EliotJones/LetsShip - hopefully gets you some of the way, it uses VS on Windows for development but I can't imagine the experience in Rider or VS Code for Linux is too disimilar. Individual steps here https://github.com/EliotJones/LetsShip/tree/main/docs/posts
I need to complete the full guide at some point but the end result is an application deployed on Linux with both a web app and independently scalable crawling services with zero downtime deployments. Hosted site here: https://pricefalcon.me/
For a simpler deployment without k3s, this guide is the one I originally followed for my trends site and should still work for .NET 6. https://www.hanselman.com/blog/publishing-an-aspnet-core-web...

Synchronizing access to a pool of resources
One example here https://github.com/EliotJones/LetsShip/blob/main/src/PriceFalcon.JobRunner/Worker.cs#L111 where I have several agent applications each of which may start up to 5 jobs, a job can take a couple of minutes to execute and while running the same request twice isn't the end of the world I'd prefer to avoid it. I use FOR UPDATE when selecting to take an update lock on the row in postgres (similar functionality hopefully exists for your DB).

New Core MVC App with jQuery in 2021?
I just build out a new MVP site for the purposes of a tutorial with .NET 5 and jQuery with some slightly complex front-end requirements (an interactive iFrame that validates user selections server-side on click) and though it may need to move to an SPA if it got more complex for now jQuery is fine (though assuming IE support is not needed I could have probably just used raw JS instead). https://github.com/EliotJones/LetsShip

The Architecture of a One-Man SaaS
I've done a complete 180 on this too, I realised I was reacting from my default position of hostility to new concepts rather than an honest appraisal. I am writing it up at the moment but I've been working on a 1 person SAAS MVP tutorial [0] and though I've definitely misconfigured something having the ability to go from git push to deployed to production with 0 downtime inside of 5 minutes with no manual steps is such a nice flow, versus my previous attempts of SCP and faffing around with services.
