33,543,346 | 0 | Can I simplify WebRTC signalling for computers on the same private network? <p>WebRTC signalling is driving me crazy. My use-case is quite simple: a bidirectional audio intercom between a kiosk and to a control room webapp. Both computers are on the same network. Neither has internet access, all machines have known static IPs.</p> <p>Everything I read wants me to use STUN/TURN/ICE servers. The acronyms for this is endless, contributing to my migraine but if this were a standard application, I'd just open a port, tell the other client about it (I can do this via the webapp if I need to) and have the other connect.</p> <p>Can I do this with WebRTC? Without running a dozen signalling servers?</p> <p>For the sake of examples, how would you connect a browser running on 192.168.0.101 to one running on 192.168.0.102?</p> |
39,453,787 | 0 | SQL Server 2008 R2: trigger after update <p>This is my first post so please bear with me.

Just work fine !!!</p> <p>After exporting my product (through headless build) I noticed that when launching my product I have a lot of errors in the error log view (not acceptable for customers even if all is working fine).

33,061,971 | 0 | Selecting MediaRoute on behalf of user works but MediaRoute button is in disconnected state <p>I'm building an app that will launch a chromecast receiver application automatically without the user clicking the mediaroute button and selecting a route. The user has already selected their desired route, and my app attempts to connect to it for a short period of time until it succeeds (hopefully).</p> <p>When it does succeed, the app is launched onto the correct route, however the mediarouter menu item (the one used to select routes traditionally) is not updated, it still remains in the disconnected state. Once the user clicks on it (while the app is already connected to the receiver) it presents him with possible routes, and once he selects the route (the one that is already connected to and displaying the app) the media router menu item updates itself showing that it is connected and allowing the user to disconnect on the next click. </p> <p>I would like it to be updated once successfully connected to the receiver (route). This way the user will be able to disconnect with only a couple clicks (once on the menu item, and once on the 'Stop Casting' button).</p> <p>I am using the CastCompanionLibrary, though I do not think that it matters in this case.</p> <p>I am able to launch the receiver without user action by calling the MediaRouter.Callback directly like so:</p> <p><code>mCastManager.onRouteSelected(mMediaRouter, theRoute);</code></p> <p>Where <code>mMediaRouter</code> is the <code>MediaRouter</code> instance and <code>theRoute</code> is the <code>MediaRouter.RouteInfo</code> instance holding the pre-selected receiver route.</p> <p>Also, I am open to suggestions of better implementing automatic launch of the receiver application from a service/activity.</p> |

In this example, I simply name the object <code>é</code> (altGreen-E under Windows), which is compact, distinctive and unlikely to be used for other purposes. </p> <p>So let's define an <code>invert()</code> method which reverses the sense of a promise - resolve becomes reject and reject becomes resolve.</p> <pre><code>var é = { invert: function() { var promise = this; return $.Deferred(function(dfrd) { promise.then(dfrd.reject, dfrd.resolve); }).promise(); } }; var dfrd = $.Deferred(); dfrd.promise(é).invert().done(function(str) { alert('done: ' + str); }).fail(function(str) { alert('fail: ' + str); }); dfrd.reject('*'); </code></pre> <p>As you can see, the methods defined in <code>é</code> become available to any promise created with <code>dfrd.promise(é)</code>. </p> <p><strong><a href="http://jsfiddle.net/R8Evv/" rel="nofollow">DEMO</a></strong></p> |

It should be up to the end user to think up a passphrase. Any systematic scheme you implement for generating passphrases will be vulnerable to someone attacking your system.</p> <p>I am not aware of an API or utility that does this. But if you did find such an API or utility, you should immediately be suspicious of it:</p> <ul> <li><p>any "common" scheme for generating passphrases will attract attention from people trying to defeat it</p></li> <li><p>you should be concerned that someone has incorporated a backdoor in the scheme.</p></li> </ul> <p>The second problem is that a generated passphrase consisting of random English words won't be memorable, and hence the user is likely to write it down. Once they have done that, your security is defeasible by looking for bits of paper in their stolen wallet, etcetera.</p> <hr> <blockquote> <p>Well, I am also generating a random url and with each url a pin will be associated. URL is sent thru mail but PIN will be texted on their cells.

7,405,278 | 0 | DDD: how to keep a complex value object immutable? <p>I'd like to model an <code>Address</code> as a value object. As it is a good practice to make it immutable, I chose not to provide any setter, that might allow to modify it later.</p> <p>A common approach is to pass the data to the constructor; however, when the value object is pretty big, that may become quite bloated:</p> <pre><code>class Address { public function __construct( Point $location, $houseNumber, $streetName, $postcode, $poBox, $city, $region, $country) { // ... } } </code></pre> <p>Another approach whould be to provide the arguments as an array, resulting in a clean constructor, but that might mess up the implementation of the constructor:</p> <pre><code>class Address { public function __construct(array $parts) { if (! isset($parts['location']) || ! $location instanceof Point) { throw new Exception('The location is required'); } $this->location = $location; // ... if (isset($parts['poBox'])) { $this->poBox = $parts['poBox']; } // ... } } </code></pre> <p>That also looks a bit unnatural to me.</p> <p>Any advice on how to correctly implement a pretty big value object?</p> |

6,432,324 | 0 | <p>Ooo, a good question :)</p> <p>As far as I know, Mark and Sweep is only used for reference counting event listeners since they're the only ones that can have 'weak listeners'. Everything else is straight up memory reference counting. Essentially, your biggest problem would be cleaning up event listeners, but if the event listeners are within your class (listening to itself, or it's children or even outside events) they should be GC'ed properly if the object is dereferenced throughout your app (don't store it somewhere else).</p> <p>If you let object or properties be publically visible, it is possible for other classes to references them and it could prevent GC of your class (it really depends how it's referenced and all). The only to combat that is to try to encapsulate as much as possible (one class handles it's own dereferencing; look into IDisposable) so that others can't reference and try to adhere to good coding practices (preventing spaghetti code).</p> |
