This screenshot shows strong evidence of:

1. OpenSSL cross-compatibility.
2. tpm2-tools cross-compatibility.
3. Linux kernel compatibility (as in trusted keys and in future also asymmetric keys).

In tpm2sh 0.15.14 TPMKey ASN.1 policy engine starts to be actually stable. I've committed into not expanding features up until key and cache management are polished and it starts to deliver results :-)

@mupuf,
Ya, looks great!

I've started to use this package for Typst called 'pitorita', which allows to do diagrams embedded to the document you should check this out:

https://typst.app/universe/package/pintorita/

IMHO, it's also investment to decks with typst because you get from every presentation bunch of re-usable slides and diagrams :-)

tdf is super nice previewer when doing presentations, have "typst watch" refreshing it :-)

BTW, diagram is also made with Typst.

Developing a rendering engine for mailweb 0.3. The gist in that is Servo rendering the mail as a set of offline rendered tiles.

Given that Servo is complicated I'm figuring offline rendering part in a separate project.

I needed some tileable content to work with so I wrote "a classic" fractal cloud generator out of my memory (decades ago literally) ("diamond alike" recursion and periodic perlin noise) :-)

This was also great finding: https://github.com/rust-windowing/softbuffer

I'm using Servo in the next (0.3.x) version of mailweb, which will no longer open browser like viewhtmlmail.

Instead using servo this will happen when showing HTML mail in mutt:

1. Render page as bitmap(s) to the cache after extracting CID shenanigans using Servo.
2. Page is showed then in the terminal sixel first and fallback to unicode rendering.

This way sixels performance issues won't get in the way and will overall much nice experience than opening a random tab in a browser.

I created a cheat sheet of my accumulated custom shortcuts in vim using typst. i'm going to maintain this and capping custom shortcuts to fit into single A4 helps to make sure that things don't get too complicated :-)

tpm2sh 0.15.0 compiles the policy commands to the DER payload.

Crypto has been migrated to OpenSSL for sake of allowing to be (or delegating the policy of being) FIPS compatible, and making crypto patchable.

tpm2sh 0.12.3 loads and processes multi-level ancestor chains correctly, policy expressions have now a more stable manually implemented custom-built parser.

Noteworthy in this is the implict parent discovery without having to specify parent when loading keys :-) It recursively loads always the whole hierarchy where parent key is discovered either among persistent keys or cache.

After starting this work one Sunday on August and ~13000 lines of new Rust code after that, this is the first release where I don't have any catastrophical bugs to resolve, or have personally any immediate needs :-)
