Notes from Calibrating Memo of Howard Marks

“What I would to is figure out how much you’ll want to have invested by the time the bottom is reached”
 
“All great investments begin in discomfort. One thing we know is that there’s great discomfort today”
 
“Oaktree explicitly rejects the notion of waiting for the bottom; we buy when we can access value cheap.”
 
“The investor’s goal should be to make a large number of good buys, not just a few perfect ones.”
 

Remotely connecting to existing X server via VNC server

My goal was to connect to a remote desktop. Had to tweak systemd to autologin with specific user.

sudo vim /etc/systemd/system/getty@tty1.service.d/autologin.conf
[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin mike --noclear %I $TERM

I’m a zsh user so had to add the following into ~/.zprofile

if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
    exec startx
fi

So after these changes after rebooting the PC the X server started and I could connect to it.

Just had to start 

x0vncserver -display :0 -rfbauth .vnc/passwd

 Geometry:    Desktop geometry is set to 3840x1200+0+0
 XDesktop:    Using evdev codemap
 XDesktop:    
 XDesktop:    XTest extension present - version 2.2
 XDesktop:    RANDR extension not present
 XDesktop:    Will not be able to handle session resize
 Main:        Listening on port 5900

The desktop has no public IP so I had to port forward

ssh vnc-server -L 9900:localhost:5900

Now I was able to connect with vncviewer

vncviewer localhost:9900

EZVIZ C3W IP cam RTSP URL

Finally got the stream URL
