13,089 | 13,090 | Android: SMS and contacts data access | <p>I'm trying to do a backup & restore application and I want to backup all SMS and all contacts informations. I read a lot about content providers but I first tried to copy these <code>contacts2.db</code> and <code>smsmms.db</code> files (the lazy and easiest way I figured out ) with no success because of permission issue (these databases are private).
Now it seems like content providers remain my only issue. I thought about accessing each data field in both SMS and contacts, store it in files(XML format) with a specific structure, being easy to read and restore.
Is that a good way? Are there any other easy ways instead of content providers for my backup & restore purpose?</p>

<p>What I'm trying to do is to get the camera-preview-pictures in bitmap format, before they are drawn to the camera-preview's surfaceView!, then i want to manipulate the bitmap with computer-vision-algorithms, and eventually draw them on the camera-preview's surfaceView.<br>
I'm able to get YuvImages from the camera-preview using the callback's onPreviewFrame() method, further I'm able to manipulate them as needed and I'm able to draw pictures on a surfaceView using a thread. BUT I can't figure out how to combine those tasks.<br>
The problem is that the preview's callback automatically draws it's pictures to its surfaceView, so when I get the pictures in the onPreviewFrame() method, they were already drawn to the surfaceView. How to change this behaviour? I could find no solution.<br>
I thought it might be a workaround simply not showing the preview's surfaceView, but another one, where the manipulated pictures are drawn on, but I couldn't get this solution working either... </p>
<p>I hope you guys could help me, because I'm already frustrated. </p>

If I don't have the console open when running the page, it doesn't stop, only when console open. I also can't click on the breakpoint to disable it. It also happens, in this instance and others, that when I'm trying to get access to the file with the custom javascript it's not showing up in the sources presumably because things have stopped loading. I click the ||> arrow to push through the breakpoint, but the file with the javascript never loads in scripts, so I can't set breakpoints where I want.

4,334,274 | 4,334,275 | Possible to capture entire call stack from a jQuery call? | <p>Admittedly, a strange question....but is it <strong>possible</strong> to somehow capture an entire javascript call stack from jQuery? For example, let's say on page ready, I do a for each on every row in a table, and for a certain cell in each row, I want to change the row color based on this cell exceeding a certain value.</p>
<p>So, I'm wondering if it is possible to write this in jQuery, execute it, and somehow end up with an entire stack trace of the actual javascript that was executed?</p>
<h2>Update #1</h2>
<p>Hmmm....this looks very similar to what I am hoping for (looks like it must be technically possible):<br>
<a href="http://getfirebug.com/logging" rel="nofollow">http://getfirebug.com/logging</a> </p>
<p><strong>Stack traces</strong><br>
<em>Just call console.trace() and Firebug will write a very informative stack trace to the console. Not only will it tell you which functions are on the stack, but it will include the value of each argument that was passed to each function. You can click the functions or objects to inspect them further.</em></p>
<h2>Update #2</h2>
<p>Ah of course, the question is: why?<br>
How about this: javascript is allowed at my company, but jQuery is not.</p>

1,805,244 | 1,805,245 | How can I achieve safe user-generated client script execution? | <p>So we all know that <strong>eval</strong> is bad, and allowing users to create their own JavaScripts to run on your site is just potentially VERY dangerous, opening doors to all kinds of security risks.</p>
<p><strong>My challenge however, is to come up with a solution, to allow users to create their own custom script snippets, that will execute on the client side. These scripts are basically prediction algorithms, that allow each individual user to build their very own customized prediction strategy, calculating and processing a set of data provided to them via AJAX.</strong></p>
<p>Basically, on regular time intervals, an AJAX request is made by the system, a JS event is trigerred, notifying the client side each time new data has arrived. The above user scripts are allowed to hook into/subscribe to this event, executing the users algorithm on the received data, and outputting the result of their algorithm.</p>
<p>The following problem I have...If I allow users to create their own JavaScripts, they can pull all kinds of fancy tricks, like make cross browser unauthorized AJAX requests, invoke unintended input events and in plain short...attempt to hack the system with malicious intent.</p>
<p>I need to encapsulate these scripts, restricting them from using the browser context. For example they cannot make AJAX requests, or invoke click events on the page. The only access they have is to the data supplied, via a pre-determined input>process>output interface.</p>
<p>So my question is, how can my site, give users, SAFE, limited, scripting access? Is there for example a Lua script parser written in JavaScript or something likewise that can be utilised?</p>
