I am using SQLite on paperless-ngx (an app to manage pdf [4]).
It is quite difficult to beat SQLite if you do not have a very huge parallelism factor in writes.
SQLite is an embedded database: no socket to open, you directly access to it via file system.
If you do not plan to use BigData with high number of writers, you will have an hard time beating SQLite on modern hardware, on average use cases.
I have written a super simple search engine [1] using python asyncio and SQLite is not the bottleneck so far.
If you are hitting the SQLite limit, I have an happy news: PostgreSQL upgrade will be enough for a lot of use cases [2]: you can use it to play with a schemaless mongo-like database, a simple queue system [3] or a search engine with stemming. After a while you can decide if you need a specialized component (i.e. Kafka, Elastic Search, etc) for one of your services.

A tiny layer around stareless docker cluster.
I created it for my homelab and it gone wild
Self-hosting is becoming a freedom factor in my humble opinion.
I have an hard time hosting my email server, it was not so diffcult 10 years ago and was trivial 20 years ago.
The reason is the anti-spam rules and the fact that Google, Microsoft and so on are creating a iron trust to each other, and the little server outside are marked spam by default.
Lets encrypt avoided a similar destiny to https connections, but the risk is always out of the window.
I mean, https was becoming "pay-us-to-publish a web server, or our browser will mark you as unsafe and do not display it".
I think it is time also to self-host private free chats and possibly other services lik DDoS services.
I keep using isso https://isso-comments.de/
I installed it on my static blog very easily, and I own all the data.
Also it is GDPR-compliant (because it provide hints on how to remove data like IPs) and it is very light.
For me Disqus and similia are a dead end.
I do not know: the lack of proper docker compose support it is a problem for me.
About security: gVistor adoption failure in Google is a proof that containerization cannot be enforced easily and container will always be less secure than a VM.
If you want proper security go to firecracker [^1].
Podman is the "RedHat/IBM docker-way" but I see very little benefit overall; never less if it works for you great and go with it!
I do not know. I learned it when I was 12, but it was quite challenging for me.
Pros:
It is very ortagonal, has no memory-to-memory instructions
Zero page is like a having 256 generic RISC registers (a bit faster than accessing to other memory areas).
Very easy to understand how the assembly is micro-coded
Cons:
It is impossible to create a "generic" memory pointer with an index >255 without auto-modifying code.
It is a true 8bit only system and cannot manipulate 16bit word easily
Steve Wozniac created a small VM just to manage 16 bit Integers (see the his Byte magazine articles).

It works very well!
