LPI Certification Material

    At one time I really wanted to take the  LPI certification  but I feel my experience speaks for itself. However I do want to cover the material and refresh myself on some of the stuff that I don't use on a regular basis. I bolded the commands I use the least and reworded the description a little more to my liking. Most of the information is just examples I found and stuff I think would be covered. Commands declare - Use the declare command to set variable and functions attributes. quota - displays users' disk usage and limits. By default only the user quotas are printed. date  - display or set the time. rpm - package manager. (I prefer debian) xvidtune - tweaks the screen resolution. nl - prints line numbers before each line in a file. od  - dumps files in octal format. su - option m is pretty useful, do not reset environment variables. mkfs - “used to build a Linux file system on a device, usually a hard disk partiti...

AngularJS: Facets in a Search Grid

    Sometime back I really needed this code however it came a little too late and unfortunately didn't make it into the final product. However I have since then built a complete explain showing how to hand facets with little javascript code and with a whole lot of functionality! Requirements Load appropriate facets, make a search. Update the UI, reload page if necessary but scale up for a single page application. Make things bookmarkable but don't lose that awesomeness from SPA's. Example http://jsfiddle.net/t7kr8/211/  - I forget where I found this but its probably buried somewhere in my resources. My Example https://fassetar.github.io/blog-examples/catalog-facets/ Javascript code var myApp = angular.module('myApp', []); myApp.controller('mainController', function($scope) { $scope.items = [{ item:"apples", flag: true }, { item:"oranges", flag: true }, { it...

Chrome Console Log Styling

Image
     The devtools console is probably one of my best friend when it comes to web development and it just so happen that one day when I was randomly looking at the console while visiting facebook. What I found was some styles being applied to a console.log command. After looking a little into this cool new concept I found what many would find after doing a quick search. Example console.log( ' %c Hello World!' , 'color: white; background-color: black; font-size: 70px;' );      I really like the image example I found (in the resources), this just leaves me wondering what can't you do in the devtools console. I know awhile back I even saw that you can use "require" to install modules into chrome. Side Note     I learned there are two short-cuts to pull up the devtools console. There's Control-Shift J which I use and Control-Shift I. Probably will just stick with J though. Also this I already knew but just wanted to share because I think...

Project: DuckSauce Notes Part IIII

     A lot of this article not going to make sense to people because it relates to my thoughts as I wrote them down and what I researched or tried to understand. Some of it is wrong, and looking back probably could have approached somethings better but that's just a natural way of learning.  Also a lot of my notes are going to appear as if I'm going in circles (or that's just how I see it). Previous articles can be found here . Day 1- 10/2/14     I started looking at the   chrome . devtools . panels . openResource , by resources I think the docs means a web page's resources not the devtool's resources (something that  work-spaces  might have access to).  The next part, "Requests DevTools to open a URL in a Developer Tools panel."  " The real power of  Work-spaces  lies in being able to map a local file to a URL (or “Network Resource”). Whenever Chrome loads the mapped URL, it displays the  work-space  fol...

The Four Components of a Web Application

Image
    If I had to go back in time and explain to myself web development (primary what most call front-end) in a nutshell this is how I would organize it. I would purposely leave out explaining to myself any middle tier or backend frameworks as I would place those types of technologies in another category. Which may or may not be how others organize it but I'm open to suggestion . Hey these colors look familiar! Structures ( HTML) Not to be confused with styles, controls the structure/flow and order of things. Ignore tags like bold or italic because they kinda break this idea. The same could  kinda be said about  a break tag. Styles (CSS) - looks, not functionality but the two do work together a lot! Mobile first baby! Content (Other) -  separate  from all the rest but drives the app is in  Forget for a moment everything you know about databases, middle-tier, back-end or whatever there is that draw...

AngularJS: Select All Checkboxes

    There were very few examples I found on this idea however most of them were not complete or depended on libraries were not included in my projects. I could simply include them and call it a day but that would be too easy. So I took the best example I could find and rewrote it in just AngularJS. Code: $ scope.items = [ {item: 1 , flag: true }, {item: 2 , flag: true }, {item: 3 , flag: true }]; $scope . allNeedsClicked = function () { var newValue = ! $ scope.allNeedsMet(); for ( var i = 0 ; i < $ scope.items. length ; i ++ ) { $ scope.items[i].flag = newValue; } }; $scope . allNeedsMet = function () { var needsMet = []; for ( var i = 0 ; i < $ scope.items. length ; i ++ ) { if ( $ scope.items[i].flag === true ) needsMet. push ( true ); } console .log ( $ scope.items. length , needsMet. length ); return (needsMet. length === $ scope.items. length ); }; Solution:  https:/...

Javascript: Loop with Deferred Calls

    This is a solution I can across that really helped me out in a bind. I need to use a for loop with a series of calls, and each call took sometime to execute. So I looked at how I could make the calls asynchronous rather than synchronous. (function def() { var def = (new $.Deferred()).resolve(); var list = new Array(15);//My hacky way of doing it. $.each(list, function (index, val) { def = def.pipe(function () { return calls(index); }); }); })(); Example:  http://jsfiddle.net/nkzqa82s/7/ This example doesn't completely show the advantages but more of how the concept work. With my problem what I had was a multi-leveled or hierarchy rather leveled system of data. So data that I requested was start at the top level and return lower levels, then with values I would request the data for each values' lower level. This process worked for me but I'm  not able to completely show  for a number of reasons. Notes     If you look at...

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...
