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

What is a common set of algorithms in a "typical" TPM2 chip at Chinese market. I.e., something like Infineon 967x but SM3 based?
I dropped MockTPM from tpm2sh but I'm plannig to resurrect it as a focused and almost zero configuration TPM emulator with exactly two preset configuration. I will pay also attention to QEMU integration. I think presets could be even named after chips.
Options will be something along lines:
1. --cache-dir
2. --preset (not sure about option name yet)
3. Options for supplying certificates for endorsement CA.
That's it.

Through dependency graph GItoxide has a RSVM requirement of 1.88.
For me that means exactly to never use Gitoxide and stick using libgit2 bindings because they retain software ubiquitos across environment and toolchains.
This also thought me an important lesson: using well established C-library throught bindings is 9/10 times a better choice than using equivalent "pure Rust" implementation. This does not mean that the Rust implementation would be somehow"worse", generally it just seems that Rust developers are completely ignorant of optimizing things like RSVM.
That leaves you two options.
1. Use a really old version of "pure Rust" library in order to maintain RSVM of your choice. Usually this means using a version, which never will be updated.
2. Use Rust-bindings of a C-library and have always up to date version of the dependency while retaining RSVM of your choice.
The crazy RSVM requirement of Gitoxide zeros down its applicability for anything production. I will never touch it again.

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.

WebAssembly is one of the worst ideas in the industry during past 10 years. why end up with stack machine and purposely complicate JIT. Never really grabbed it engineering wise TBH but maybe I'm missing something who knows.
You don't need to be an engineer to get it. It just tends to be easier to find ways map registers to registers, and requires more stretch to move between stack and register machine.

linkedin i scroll posts and spot at least three posts from someexperts about DAC permission and how to decipher them.
dude, you have like left and right plus one more state. i could explain DAC to my mom who does not anything aboutc omputers or permissions and i'm confident that she would get it.
other posts are the usual 2025 AI crap. i made account mostly to backup CV somewhere someday and curiosity after many years away from.
it does deliver shit and i do get some entertainment for boring moments so i guess it is a great service then 🤷

split zmodem2 into two separate projects:
1. https://crates.io/crates/zmodem2
2. https://crates.io/crates/lrzsz2
this will still need a lot of love before being a production tool but working batch transfers (against lrzsz) is good start.

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 :-)
