Unable to build in Appcelerator Studio

I have a problem with Appcelerator Studio. The build process stucks for a little to:

and then reuturns me an error

"Failed to run dexer"

I've tried to uninstall everything, including the Android SDK and install again but with no success

My system has Windows 8.1 OS 64-bit, an i run both 32bit and 64bit versions of Java because I'm learning this period Android Studio.

Laravel hide files on server

Currently I've put my laravel site online (just for testing). But when I go to for example www.mysite.nl/.env it shows my password etc. for my database. How can I prevent this?

Split up latest commits into multiple branches

I'm aware of several questions on the subject, but I didn't find any that address this situation. The trick is that I need to pull one commit out from between two others.

My repo looks like this:

A - B - C     <- master
          \
            D  <- devel

and I want it to look like this:

    C  <- feature1
  /
A
  \
    B - D  <- feature2

I know I can probably use rebase for this, but after a year of using Git I'm still not clear on all the jargon.

Handling text containing both quote types

I want to append the following text to a file in Linux:

echo He said "I can't append this" >> file.txt
cat file.txt
He said I can't append this

How do I include both sets of quotes in the appended string?

Angular ng-repeat best practice to only watch for updates inside the specific iteration

I need to render a table in which the user is allowed to edit some fields for each row, fields that will affect other fields in the same row.

For this reason I could not use bind-once on all the data I'm rendering.

If I got it right, simply using a code like the following

<table class="table table-bordered table-condensed table-hover">
  <thead>
    <tr class="info">
      <th>Header</th>
      <th>Header</th>
      <th>Header</th>
      <th>Header</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="a in alist">
      <td>{{::a.id}}</td>
      <td>{{::a.cod}}</td>
      <td>
        <input
          ng-model="a.sel"
          type="checkbox"
          class="input-sm"></input>
      </td>
      <td ng-if="a.sel">
        {{::a.desc}}
      </td>
      <td ng-if="!a.sel">
        "Other Content"
      </td>
    </tr>
  </tbody>

will cause that for each time a user checks or uncheks the a.sel checkbox, all the angular {{vars}} in the page (not the {{::vars}}) will be watched for changes.

If this is true (and therefore that's the reason why page is slow when hundreds of rows are loaded) how could I tell angular I only want it to check if something has changed inside that specific row, that specific ng-repeat iteration?

Not sure how to proceed to get good performances, any other tips are appreciated.

Thank you for your help.
