A painful processToday, kernel maintainers who want a kernel.org account must find someone already in the PGP web of trust, meet them face‑to‑face, show government ID, and get their key signed. The process is like a manual, global scavenger hunt. Linux kernel maintainer Greg Kroah-Hartman, speaking at the Linux Foundation Members Summit, described it as a "pain to do and manage." That's because it's tracked by manual scripts, the keys drift out of date, and the public "who lives where" map creates privacy and social‑engineering risk.
Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.，更多细节参见heLLoword翻译官方下载
