39,582,650 | 0 | How do I bind alpaca.js to an existing HTML form <p>I have an existing form in plain HTML with a lot of css and layout tweaks. I'm trying to figure out if I can use alpaca.js without the rendering step but still get the full power of the schema and validation capabilities. I looked at Views, Layouts, Templates, etc. within the docs, and was either blind (probably) or just making some bad assumptions, but there didn't seem to be a simple way to declare <code>schema-property-FOO</code> should be bound to <code>#html-element-BAR</code>. It seems like something that would be mapped out in the <code>options</code> section of my alpaca declarations, but no luck (that I saw).</p> <p>Essentially I want all the alpaca goodness without the rendering step. Is that possible, or square-peg/round-hole thinking?</p> <p>Thanks for any guidance.</p> |
29,048,621 | 0 | android app data not appearing on parse dashboard <p>I'm trying to make a new social app. I went parse.com and made a new app. downloaded the zip file and opened it in the android studio. after that i initialized my keys and compiled the code. It gave no errors and loaded the app on the emulator. Then i added the code to add new user to the database and ran the app. All went ok and log cat didn't give me any errors but when i pressed the test button to check if data got added in the cloud or not but it said "no data yet". yes i did initialize the keys right and my manifest file does include internet permission. Can anyone please tell me whats wrong? I copied all this code from parse</p> <pre><code>public class ParseStarterProjectActivity extends Activity { /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ParseUser user = new ParseUser(); user.setUsername("my name"); user.setPassword("my pass"); user.setEmail("[email protected]"); // other fields can be set just like with ParseObject user.put("phone", "650-555-0000"); user.signUpInBackground(new SignUpCallback() { public void done(ParseException e) { if (e == null) { // Hooray! Let them use the app now. } else { // Sign up didn't succeed.

5,149,574 | 0 | Deploy two connected webparts in a page layout during feature activation? <p>I've implemented 2 webparts (deriving from Microsoft.SharePoint.WebPartPages.WebPart, the WSS 3 WebPart), one of which is a provider and the other the consumer (implementing ASP.net connection model, with <em>ConnectionProviderAttribute</em> and <em>ConnectionConsumerAttribute</em> methods).</p> <p>I managed to deploy them in a feature which also deploys a Page Layout containing two webpart zones, which are themselves populated during the FeatureAvtivated method of the feature receiver, with the 2 newly created webparts. All of this works just fine.</p> <p>For information, I used <a href="http://vspug.com/michael/2009/05/25/manage-webparts-of-page-layouts-through-a-feature-resolving-the-quot-alluserswebpart-quot-pain/" rel="nofollow">this link</a> to make it work. Beware, the method using <em>AllUsersWebPart</em> tag in <em>elements.xml</em>, shown in links like this one (http://www.andrewconnell.com/blog/archive/2007/10/07/Having-Default-Web-Parts-in-new-Pages-Based-Off-Page.aspx) work, but if you deactivate, then reactivate your feature, you just have double webparts in your future pages based on the layout. The method described here (http://sharepoint.coultress.com/2008/06/adding-web-part-to-page-layout.html) just threw me an error when analysing metadata for the layout aspx file (the problem seemed to come from the line in the ZoneTemplate tag).</p> <p>My next goal is to connect these webparts together right after all this, thus enabling the end user to create pages, based on the layout, containing <strong>by default</strong> the two webparts <strong>connected</strong> together (right now everything works except for the <em>connected</em> part).</p> <p>I tried something like <a href="http://vspug.com/jason/2007/06/21/how-to-connect-web-parts-programmatically-in-wss-3/" rel="nofollow">this</a>, using ASP.net connection model (the other one, WSS model, throws logically an error because I'm not implementing the good interfaces). But even though the connection resulting from the "mgr.SPConnectWebParts()" method doesn't throw any exception and actually adds the connection to the connection list of the webpart manager, I can see in debug mode that the connection property 'IsActive" is false (maybe normal), and that when I create a new page based on the layout, the webparts appear not connected.</p> <p>Any guess? I believe there's something with the fact that the webparts cannot be connected before the page containing them is actually created, but I'm far from sure of it.</p> |

16,921,721 | 0 | <p>Your solution is not so bad. The queuing of the HTTP requests is really a standard thing to do, so that should not be a big problem. </p> <p>Just do <em>not</em> use the objectIDs on your server. They are really unique to the database on one particular device. Their main purpose is to identify managed objects across different managed object contexts. Instead us your own id, maybe a server generated one that is authoritative. </p> <p>The obvious "elegant" alternative is to use Apple's integration of iCloud with Core Data. Then you have to do absolutely nothing on the server side. The drawback is that you cannot access the user info (which might be desired).

12,872,568 | 0 | <p>For a perfect effect you will need to do 2 things. Assuming you used Image class to render it, first, is to put the same image bellowthe original one and use the scaleY to flip it vertically.</p> <p>this will create reflection effect, but you will need to apply same things that you applied to first image to the second one, like movement, rotation, whatever you did to it.</p> <p>Besides that you will probably need your reflection image to fade out like a gradient, if you are doing everything on a solid not moving background, you can create a third image which is a gradient png from transparent to the color of your background, and put it over the reflection image. If you have a dynamic background, then you will probably need to use shaders (sorry, openGL 2 only). You can read more on how to write custom shaders here: <a href="http://blog.josack.com/2011/08/my-first-2d-pixel-shaders-part-3.html" rel="nofollow">http://blog.josack.com/2011/08/my-first-2d-pixel-shaders-part-3.html</a> (A great tutorial)]</p> <p>Hope that helps.

3,595,562 | 0 | <p>I just went through the process of installing and trying several carts for a project that I was working on. As Pierre says above, "There is no best shopping cart, however there is one best for your specific need" That is a very truthful statement.</p> <p>My project was for an on line soap company that has 5 different categories with 5 or so variations each. Not a big store and not one that changes inventory often.</p> <p>I tried the following carts: PrestaShop, Zen Cart, Magento, getshopped and phpurchase.</p> <p>My findings were that for a small store, PrestaShop, Zen Cart and Magento are a bit overkill. For a small shop, getshopped and phpurchase are better fits.</p> <p>Out of the 3 big shop solutions, I felt that Zen Cart is really hard to make look nice. It has a 90's vibe about the template that it comes with and takes a lot of work to get around that. Magento and PrestaShop were really cool. PrestaShop seems very UK specific. It did not take Authorize.net and I think that there may be a plugin that you can get. Magento seems like a great solution for a larger store and I liked the backend admin interface.</p> <p>I purchased getshopped plugin and integrated it into my Wordpress site (I purchased the Authroize.net integration gold cart level) I had such trouble dealing with the multiple bugs that I found riddled through the code base. I looked at their forum and many people who had similar issues were not responded to. Alot of people were as frustrated as me. I tried customer support - no response. I asked for a refund, no response. Basically, Get Shopped was a complete waste of time and money.</p> <p>I then found Phpurchase. The customer support person, Lee Blue was really nice - Lee answered my emails morning, noon and night. Lee is literally the nicest customer support person I've ever worked with! - so helpful. The code worked just as specced - no troubles and no complaints. I'm a very happy customer with phpurchase. If I need a small ecommerce site in the future, I will use that solution again, for sure. </p> <p>Note, I'm not an affiliate of Phpurchase or have any type of financial gain by recommending them, I just had such a rough time with getShopped and such a wonderful experience with <a href="http://www.phpurchase.com/" rel="nofollow noreferrer">Phpurchase!</a></p> |

759,223 | 0 | <p>Yes. A float (or double) is guaranteed to exactly represent any integer that does not need to be truncated.

JavaScript events fire <em>synchronously</em> — that is, in series with the browser’s own handling of the web page. That’s why it's possible to prevent a form from being submitted or prevent a keypress or mouse click from being registered from within an event handler.</p> <p>The last time this bug was fixed in Firefox, the cause was that the removing an <code>iframe</code> from the page makes it forget which page owned it, but the <code>iframe</code> notifies the page that it was finished loading <em>after</em> the <code>load</code> event.</p> <p>Anything you schedule with <code>setTimeout</code> happens after the current cycle of the event loop — after the browser finishes what it’s doing <em>right now</em>. So, using setTimeout to remove the <code>iframe</code>, even with a timeout of zero, lets it finish:</p> <pre><code>iframe.onload = function(){ // Do work with the content of the iframe… setTimeout(function(){ iframe.parentNode.removeChild(iframe); }, 0); } </code></pre> <p>You can find this technique in use <a href="https://github.com/malsup/form/blob/e77e287c8024d200909a7b4f4a1224503814e660/jquery.form.js#L511" rel="nofollow">in the jQuery form plugin</a>.</p> |

714,475 | 1 | What is a maximum number of arguments in a Python function? <p>It's somewhat common knowledge that Python functions can have a maximum of 256 arguments. What I'm curious to know is if this limit applies to <code>*args</code> and <code>**kwargs</code> when they're unrolled in the following manner:</p> <pre><code>items = [1,2,3,4,5,6] def do_something(*items): pass </code></pre> <p>I ask because, hypothetically, there might be cases where a list larger than 256 items gets unrolled as a set of <code>*args</code> or <code>**kwargs</code>.</p> |
4,657,548 | 0 | <p>That's an error Windows gives when you're trying to bind to an address on the local machine that's not assigned to any of the adapters on the machine. If <code>ipconfig</code> doesn't show it, you can't bind to it. </p> <p>If the external address is on a router that is NAT'ing requests from it to the server's internal address, you can't bind to it because it's on a different machine. This is probably the case. You might want to bind to <code>socket.INADDR_ANY</code> (or its Django equivalent). This will bind to all addresses that are on the machine right now.</p> <p>Also note that if the external address is NAT'ed to your internal one, binding to the internal one should be enough.</p> |

35,260,364 | 0 | <p>While it is acceptable to return pointers to the string literals, buit not to a local pointer, it might be the wrong approach.</p> <p>If <code>str</code> does not change, make it <code>static const char * const str[] = ....</code> That qualifies both, the array and the <code>char []</code> (which is each string literal) it points to const. The <code>static</code> makes it permanent, but with still local scope. It is setup once before your program code starts. In contrast, a non-<code>static</code> version will setup the array for every call.</p> <p>Note that you have to return a <code>const char *</code> to maintain const-correctness. I strongly recommend that; if you cannot, omit the first <code>const</code> only.</p> <p><strong>Note:</strong> Do not cast the result of <code>malloc</code> & friends (or <code>void *</code> in general) in C.</p> |
