bita VS d2

Built this cdc tool for software update of embedded (Linux) systems and have deployed it with good enough performance on a couple of arm CPUs; https://github.com/oll3/bita

Though main goal has been keeping data usage low rather than speed up.

Nice write up. rsync is great as an application but I found it more cumbersome to use when wanting to integrate it into my own application. There's librsync but the documentation is threadbare and it requires an rsync server to run. I found bita/bitar (https://github.com/oll3/bita) which is inspired by rsync & family. It works more like zsync which leverages HTTP Range requests so it doesn't require anything running on the server to get chunks. Works like a treat using s3/b2 storage to serve files and get incremental differential updates on the client side!

Very cool, thanks for sharing. I did a deep dive in the past into various syncing/binary diff protocols and really liked zsync. It was probably my top choice for the application I was designing but I ended up not using it. The library I did use is called bita: https://github.com/oll3/bita. It is inspired by the same family of projects as zsync. The main advantage I found with bita is that the core logic is encapsulated in a library so that you don’t only have to use the binaries but can integrate it directly into an application. I’d be curious to know if that’s in the plans for KySync.

While not embedded in markdown, I like d2 [1]. I can use it with org-babel to embed and view the diagrams on emacs. After using graphviz for years, the visual output seems more polished to me. With that said, I want to give pikchr a try.

In the next post I'll deep-dive into the D2 language which also has a huge set of features. Stay tuned.

That site is created by the maintainers of D2[1], so it might be biased, but I still think D2 has the friendliest syntax of the bunch, including nomnoml.

I've been using https://structurizr.com/ to automatically generate C4 diagrams from a model (rather than drawing them by hand). It works well with the approach for written documentation as proposed in https://arc42.org/. It's very easy to embed a C4 diagram into a markdown document.

The result is a set of documents and diagrams under version control that can be rendered using the structurizr documentation server (for interactive diagrams and indexed search).

I also use https://d2lang.com/ for declarative diagrams in addition to C4, e.g., sequence diagrams and https://adr.github.io/ for architectural decision records. These are also well integrated into structurizr.
