a somewhat reasonable python2.7 on macos in 2022

Yes, this sucks, but look, there are still python2.7 projects out there. Homebrew did the wrong thing by removing their 2.7 forumla.

The system python2.7 doesn't have ability to install virtualenv or even pip. ☹️

That said, use homebrew to install zlib and bzip2 and maybe openssl as deps.

If you are using a server or cloud image, you may not want to install the necessary packages to get add-apt-repository. /etc/apt/sources.list.d/ is empty by default so you can edit only /etc/apt/sources.list.

Without comments, OOTB docker image looks like this for me:

deb http://archive.ubuntu.com/ubuntu/ bionic main restricted
deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted
deb http://archive.ubuntu.com/ubuntu/ bionic universe

	Alright, so I'm standing on a cliff that's 307 meters above the water. Someone is shooting a
	cannonball with a mass of 40 kilograms using a cannon. The cannon fires the ball at an angle of
	37 degrees and accelerates it to a speed squared acceleration of 800 m/s². I need to figure out
	how far from the cliff the ball will land in the water, assuming there's no air resistance.

	My MacBook had load over 600, even after a reboot it was unusable (load still 500+).

	I looked at Activity Monitor and noticed kernel_task was maxing out as much as it can and so was syslogd.
	I looked at recent writes to log files in /var/log and noticed junk from acnvmagent.
	I killed that process. It came back.
	I ran `sudo chmod 0 /opt/cisco/anyconnect/NVM/bin/acnvmagent` and killed the process.
	It did not come back. Now my laptop is usable again.
	Possibly relevant log message:
