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...

CSS3 Transition Rotating Does Not Fit

    Awhile back I created an application to display some data inside of a table but after it was all said and done I was then asked if I could make it so the information could be rotated. With that I thought I could easily implement this using CSS3 transition and rotate on the x-axis but I would much prefer doing this in a canvas.Which make this a great solution  but current my content is displayed in a table and isn't scalable this way, so it doesn't help for me. I could also use d3js, from what I've seen in the examples it could be easier to implement.     I did find that some created a solution to handle the issue with Css3 transition, where as you rotate the element the content around it does not adjust appropriately. There is reasons behind why this happens, but no proper way to handle it with just css . As you rotate a given element it does not remove or change any of the styles attached to it. So margin, padding and whatever else will still be applied ...

Server-side Browser Detection with Bootstrap

    One thing I love about bootstrap is that it eliminates the need to create separate views or pages to handle both types of clients (mobile/desktop) . A few years back when Asp.net MVC 4.0 first came out and before the big boom of "mobile first" styled css libraries there was a huge additional feature for server side detection. Now this was back in the early parts of my career so I was not sure where this feature would fit in or if it would ever. Since then I have been looking at all types of frameworks and server side detection systems but ultimately have been moving toward the bootstrap style mentality until I looked at my blog. Blogger actually does all the work for me so I didn't have do anything to create this.     The thought behind this is to minimize the amount of information you sent to the user. Its great that you hidden it to the user on mobile devices and even design it with them in mind. However they are still getting all that information, which see...

Bootstrap: Navbar Header

    I don't see too many examples in bootstrap with something like this but what it is incase you don't know is a banner of some kind above the navbar. In fact I don't see too many sites with this kind of structure lately and from my experience I can understand why not. If you're going for responsiveness it's difficult to create since you are always checking to see if you have enough space on both sides for whatever it is your trying to display in between. From the sites that I have seen that do have this can really pull it off and use something similar to bootstrap's affix feature.     When I first started using bootstrap which was sometime around 3.0, I was using the navbar-brand to hook into the styles already written for me. However since  bootstrap 3.1    navbar-brand   has now been given a height where before I was using the image's auto or attributes to adjust the height. I was able to give my header an even amount of padding around my he...

Razor syntax in Javascript files

    I don't always mix server side code with client side code... but  continuing  with my thoughts on  server and client models . I wanted to know if I could use razor syntax in a javascript file. Which means I woud be able take advantage of the Asp.net  Bundling and Minification  feature. Now I probably didn't bring this approach up in the article but what I did talk about was using query url with the javascript. Not being able to cache javascript files is the major reason why avoid using using it and I didn't think I would take this approach either but I did want to see if it was possible.   In my research I did notice some loss of performance, I didn't do any benchmarking but I felt the process was a little  wonky. I think the third link best describes my thoughts on this approach. So  what  I have been doing now since this is using the "data" attribute  and assigning a value with razor syntax.  It's not complete...

Compiling Bootstrap LESS using Asp.net MVC and Web Essentials

Image
    My goal is to work with others in whatever framework they choose but I'm constantly update css styles with a pre-processor so that I do not have to work with the css libraries directly. Download the   Web Essentials  and the Bootstrap less nuget package. Get this nuget package! I see it all the time where developers install the wrong packages, sometimes theres ones with similar names and you just not sure what the differences are. So just so we're clear its the first package with the bootstrap .less in the name. Just search for bootstrap less as two seperate keywords, should be no problem. Solution For this solution did  not have to change thing with my setup or move around files on the directory once I got things up and running. I even made it easier for colleagues to come into web applications without any problems so in case they are new to bootstrap they can simple ignore the less files. Now what I did was create  separate  bootstrap....

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...
