Why Linux requires 4MB of RAM no matter of kernel size?

Hi I have old 386SX with 2MB of ram hanging around and I wonder: - Why Linux requires 4MB of RAM no matter of kernel size? - Why prior to Linux 1.3(?)

Just as with my phone number and email...

With the news yesterday of POTUS joining threads.net and with the fanfare about the possibility of following him from other AP-compatible servers (like Mastodon), I was left wondering why is it that the White House couldn't just run their own services? Doesn't "POTUS is using threads for social media" feel a bit like "POTUS is using outlook.com for email"? Is there anything about the bureaucracy that stops their some small team to setup a Mastodon server on "social.whitehouse.gov" and make this a reality? I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform. Also, none of this seems to be a problem for some of the EU governments. Maybe I am missin...
