Indeepth: Inheritance with the prototype chain

These notes are for none else but me, because I need them for a bigger project. No time to explain...C# and javascript are completely different worlds.

let f = function () {
   this.a = 1;
   this.b = 2;
}
let o = new f(); // {a: 1, b: 2}

- you need the 'let' beause f.a will not exist.

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable.

Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
