Jquery Ajax with BlockUI Plugin

    I love making Ajax calls and if a user is interacting with a page and doesn't need to refresh or be redirected to another page than an Ajax call is the best thing to use in my opinion. With my best efforts I try to give my users an experience where every action has a result. This means everything even if the reaction is simple or does nothing more than alert the user. I like to let the user know that all is fine and meant to be the way it is. If an error happens they should be alerted as well. Which I should also try to prevent and recover from, but what about with an ajax call that takes a while to process? Well I have been using a really cool process with my code where I can display to my users that the process is going through. With "Please wait..." message users can see it is order is being processed and controls will returned to them when it has completed.
    You can see an example here and to go a step further then this I thought this would be a cool place to implement Gamification, by providing a small and simple game in place of the "Please Wait...". It wouldn't be meaningful for those short to medium time periods but more for those really long processing times. You could be argued that the time to developer this game could better be spent researching on how to shorten those long processes but why not do both if you can make work fun! I leave it to the users on how to spend their time. 

Problems I faced...
I had issues where I was making an ajax call but the Block was not appearing, so what I can did is use the beforeSend() and error() settings like so...
beforeSend : function() {
               $.blockUI({ message: 'OK' });
            }, 
success : function(){
               $.unblockUI();
            },
error : function() { //Close regardless
             $.unblockUI();   
             alert("ERROR!");
        }

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. Make sure port 27017 is open. Then check this  linux - Connection refused to MongoDB e...

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? 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...
