Best to use an agent that prompts you for signing. 1Password and Yubikey do this. Are there others?
Kroki [1] supports TikZ and by extension: PGF [2] and LaTeX. It supports SVG, PDF, JPEG, and PNG outputs. Rendering is done on the server. URLs can be quite long since the source is embedded in the URL but you can use a URL shortener [3].

Reminds me of Mats Järlström who challenged traffic light timing. "The [Oregon State Board of Examiners for Engineering and Land Surveying] fined Mats $500 and said that he could not talk about traffic lights in public until he obtained a state-issued professional-engineer license."

Regarding deterministic latency, the Time-Sensitive Networking (TSN) [1] set of IEEE standards address this. The IEEE P802.1DG project [2] in particular defines a TSN profile for automotive.

The table of contents feature is killer.

The AsciiDoc docs got an overhaul 2 years ago. I find them to be quite good.

What are enumerated values? Do you mean ordered lists?

Antora is built on top of AsciiDoctor.
Yes. Defaults matter. Here's one example https://blogs.iadb.org/ideas-matter/en/organ-donation-changi....

5 meters. However, the "intended target" is not simply defined.

The landing ellipse for Perseverance was 7.7km by 6.6km. The goal is to land at a safe spot within the ellipse rather than land at a specific location.

The new Terrain Relative Navigation capability determines the rovers position relative to the surface during descent by comparing camera images to onboard satellite imagery. On Earth you'd use GPS. No GPS on Mars.

Once the rover knows it's position, it can now determine the safest spot to land using an onboard hazard map. The spot it chose to land at vs the spot it actually landed at was 5 meters apart.

One take on this study: https://www.youtube.com/watch?v=NyGZW8Ml9l0

A few points:

* It is a legitimate unbiased study

* Need to consider the database used. It follows people starting in the 90s. A lot has changed with respect to vegan diets since then.

* Consuming sufficient calcium shows no additional risk in fractures

* More body weight (e.g. overweight) makes bones stronger which reduces risk of fractures
