39,417,462 | 0 | Developing two android app that can send/trigger notification to each other <p>I've been studying android development for about 2 months, and still trying to learn new things and stuffs in mobile dev. And I've been wondering how can two android application send notification to each other. I saw a tutorial about <code>notificationCompat</code> wherein a notification pop-up when an action(<code>onClick</code>) is performed inside the application. And I thought that maybe it is also possible to trigger that notification from another application. And my question is now, How can I trigger a notification in the 1st application using the 2nd application? And also addtional info will be that the two application is on the same local network(Ad hoc).</p> |

18,587,784 | 0 | <p>In TeamCity 7.1.3 you are unable to achieve what you are asking. The only way you can do this is to add permissions whenever projects are added. However, if you update to TeamCity 8.x there is now the concept of project hierarchies. You can grant permissions at any level and the permissions are inherited to the sub projects. For example:</p> <ul> <li>Project A <ul> <li>Sub project 1</li> <li>Sub project 2</li> </ul></li> <li>Project B</li> </ul> <p>If you give a developer permissions to project A and then add a new sub project:</p> <ul> <li>Project A <ul> <li>Sub project 1</li> <li>Sub project 2</li> <li>Sub project 3</li> </ul></li> <li>Project B</li> </ul> <p>There will have permission to all 3 sub-projects in project A without having to change the permissions model. This should achieve exactly what you are after.</p> |

6,815,934 | 0 | Ideas about web browser in Qt using GSM/GPRS modem <p>I have successfully interfacted Telit GL 865 GSM/GPRS modem to my Atmel microprocessor. My POC board is running embedded linux and I have also cross compiled Qt libraries(including Webkit) and transferred it to the board.</p> <p>I can also read and write AT commands from Qt application by opening an FD(File descriptor) and then executing commands.</p> <p>I'm also able to connect to the GPRS, also getting HTTP response. Currently I'm setting the HTML that I get from AT commands, through the QWebView's setHTML() function. But by this the images doesn't load(obviously) and also I cannot navigate through the links as the browser doesn't have a direct access to the Internet. So what is the proper implementation by which my Qt Webkit browser can directly communicate over GPRS using my modem ?</p> |

Start it up :-)</p> <h1>Step 2: Open the examples</h1> <p>In QtCreator you have a lot of examples that come with the software and is immediately available to test out! All you have to do is open the examples screen and find the example you want. Each example is accompanied with a lot of well written documentation.</p> <p><a href="https://i.stack.imgur.com/kKdfl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kKdfl.png" alt="QtCreator Examples"></a></p> <h1>Step 3: Search for "network"</h1> <p>In your case you want examples related to network programming. Simply type network in the search field (or anything else you want).</p> <p><a href="https://i.stack.imgur.com/iFwnC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iFwnC.png" alt="enter image description here"></a></p> <h1>Step 4: Select the example you want</h1> <p>Actually since you wanted to make a client and a server you will want to look at two separate examples called <strong>blocking fortune client</strong> and <strong>fortune server</strong>.</p> <p><a href="https://i.stack.imgur.com/CjURo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CjURo.png" alt="Blocking fortune example"></a> <a href="https://i.stack.imgur.com/lFg91.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lFg91.png" alt="Fortune server example"></a></p> <h1>Step 5: Configure the examples</h1> <p>When you click the example, QtCreator will ask you to configure the example. This simply means you have to choose which "kit" to compile the project with. This is a side-effect of the awesome fact that Qt supports a lot of platforms and a lot of versions. In your case there should probably be only one or two options. The screen looks like this:</p> <p><a href="https://i.stack.imgur.com/ef5Iy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ef5Iy.png" alt="Configuring a project in QtCreator"></a></p> <h1>Step 6: Build and run the project</h1> <p>I would start the server first and then start the client. They should be able to communicate over network. Please consult the excellent documentation that pops up for each example to find out how it is bestto test them.</p> <p>In general, to run a project, simply select the correct <strong>project/kit/build/run</strong> from the selector (see screenshot) and then press the big green play symbol.

5,587,261 | 0 | Getting my Unit of Work to... well, work! <p>I am implementing Unit of Work. This is part of my interface:</p> <pre><code>public interface IUnitOfWork { void Add(object entity); void Update(object entity); void Delete(object entity); void Commit(); } </code></pre> <p>It looks like from examples I've found online or in books, the Unit of Work is forced to work with type "object", as we can be adding any "type" of entity to the uow.</p> <p>Not a big deal until it comes time to Commit(). When I commit, given an entity type, I need to look-up the repository based on the entity type, and then call the appropriate action.</p> <p>For example, I have an entity type named Expert</p> <pre><code>public class Expert { public object ID { get; set; } public string Name { get; set; } } </code></pre> <p>Expert has a repository named ExpertRepository. All Repositories in my application implement IRepository:</p> <pre><code>public interface IRepository<T> { void Create(T item); void Update(T item); void Delete(T item); } public class ExpertRepository : IRepository<Expert> { public void Create(Expert item) { //TSQL to insert } public void Update(Expert item) { //TSQL to update } public void Delete(Expert item) { //TSQL to delete } } </code></pre> <p>I want to clarify that it is not the responsibility of my Repositories to add, update, or delete an entity from my uow, rather, I'll have the consuming code (maybe in a Service Layer) new up the uow, and then add directly to it... when my app is ready, it will call Commit().</p> <p>This does two things. It allows my consuming code to decide how it wants the entity to be persisted. Either the consuming code can call .Create() directly on the Repository to persist the entity with no uow, or the consuming code can start a uow, call .Add() on the uow, and then when .Commit() is called, the uow will go through all entities, and by action type (add, update delete), new up the appropriate repository, and the TSQL code will execute.</p> <p>Now, the problem I'm running into is when I'm looping through the Add, Update, and Delete collections in my uow. Here is a code snippet:</p> <pre><code>public void Commit() { using (TransactionScope tx = new TransactionScope()) { try { foreach (object item in addedItems) { if (item.GetType() == typeof(Expert)) { IRepository<Expert> repository = new ExpertRepository(); repository.Create((Expert)item); } } } } } </code></pre> <p>I have to resolve entity type of what's in the object collection via the item variable. Then I need to new up that entity's Repository (also providing the correct type to the IRepository interface), and then call .Create().</p> <p>That's all well and good, but I don't want to have these conditional checks for every possible entity, for the entity's interface, and the entity's repository sitting in my uow. That's very very bad.</p> <p>I know that an IoC container could help here (such as Unity), but is there any IoC container that can resolve generic types at runtime? I ask, b/c IRepository will need to be typed correctly to be a var that holds the instance of a given entity's repository.</p> <p>I've made some design decisions here such as putting the strong typing with the Repositories, not the UOW. For instance, I don't want a .Create() method sitting on a Repository that takes type object, esp. since my Repositories have a one-to-one relationship with my entities (Expert, ExpertRepository).</p> <p>I've also decided that since most of the repository calls are the same, I don't want an interface for each repository (aka, ExpertRepository implements IExpertRepository). That doesn't make sense, I think using generics here is the answer.</p> <p>But it all comes down to the problem in my uow. How do I get what I need to implement it correctly.</p> <p>Any suggestions or pointers in the right direction would be appreciated.</p> <p>Thanks!</p> |

30,517,644 | 0 | <p>I don't see you clearing the interrupt. Some UART peripherals require you to clear the interrupt or the interrupt will continue to cycle. Some will clear the interrupt automatically when the data register is read, though, so refer to the peripheral documentation. In my experience an uncleared interrupt is often the cause of a perpetually cycling interrupt.</p> <p>Also, I'm unconvinced it's your problem but, you shouldn't need the</p> <pre><code>MOVS R0, #1 ; MASK all interrupts MSR PRIMASK, R0 </code></pre> <p>and </p> <pre><code>MOVS R0, #0 ; ENABLE all interrupts MSR PRIMASK, R0 </code></pre> <p>sections of code. You shouldn't have to mask any interrupts while in an interrupt. If you're executing from an interrupt context, having properly configured interrupt priorities will stop other interrupts from triggering. </p> <p>Like others say, based on how you're using it, you shouldn't need the assembly code at all, just name your C function "UART_Handler".</p> |

(i.e. build a layer of separation between client data). Then plan for it all to be in one database.</p> <p>That way, you don't overarchitect your solution to start out with, but it gives you the flexibility to spin off very high-usage clients to a dedicated database. If your database exists with only one client in it, so what? This will also save on server costs so that you can be sure that you're using the hardware investment in a reasonable way already before adding more capacity.</p> |

38,679,082 | 0 | Breadth-first search with set instead of queue <p>I'm using BFS to find connected components. I've decided to implement it using a set to track visited nodes. The problem with that approach is that one vertex may be added to queue twice. So I just changed queue to set. I don't care about visit order, all nodes are visited once and the algorithm works fine. Of course, this is not classical BFS anymore: the order is broken. </p> <p>Pseudocode:</p> <pre><code>Set visited; Set to_visit; visited.insert(start) to_visit.insert(start) while (to_visit is not empty){ current = to_visit.first to_visit.delete(current) for each neighbour of current { isNew = visited.insert(neighbour) if (isNew) { to_visit.insert(neighbour) } } } </code></pre> <p>I'm pretty sure I'm not the first one who "invented" it.

15,939,159 | 0 | Mixed Content Warning for Forum Design <p>I'm currently designing a social network on my local host, that also has a forum aspect involved. There are three things that a user can do on the site that is causing me some concern. </p> <ol> <li>Log in to their profile via the header from any page on the site.</li> <li>Post things on their wall that include links to external sites.</li> <li>Post in the forum a variety of different things including links to external sites, and images on external sites.</li> </ol> <p>Because of #1 I made the entire site https. So no matter where a user was on the site, they could log in and their entire session would be encrypted. This functionality is working great but I am afraid of <code>Mixed Content Warnings</code>.</p> <p>Right now I'm thinking twice about making the full site secure b/c if I keep it this way will mixed content warnings appear for every page that has a link to an external site, or an image from an external site? Unfortunately I have never seen this warning b/c none of the browsers I use seem to show it to me. And I searched for some kind of list of browsers that show this warning but there is no finite list that I can find. So this is awkward b/c I'm worrying and trying to avoid a thing that I've never seen. But I have thought of one solution.</p> <p>My current idea on how to fix the image problem is to take images from users when they post a forum and write them to my disk, and provide the new image link. I am pretty sure this is exactly how google images stays https while showing millions of images from http sites. I think they write them all to their own server. Example: </p> <p><a href="https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTj_52I-TSX79mQFJRLTDNGahtGbsh_BpYDp0H3hbzJDWK2qxPZ" rel="nofollow">https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTj_52I-TSX79mQFJRLTDNGahtGbsh_BpYDp0H3hbzJDWK2qxPZ</a></p> <p>So I think I have found a solution to the image problem but what about external links? Because when a user posts a link on their wall to <a href="http://stackoverflow.com/">http://stackoverflow.com/</a> for example I read the post and surround it with an anchor tag so technically to a browser wouldn't that be none secure content? Wouldn't that throw a warning? </p> <p>How could I fix this and not annoy my users? And do you have a better solution to my image problem? Thank you all for reading through my confusion.</p> |

9,178,071 | 0 | <p>You still need to use <code>IList<T></code> instead of <code>List<T></code>, because NH needs its own collection implementation.</p> <p>Consider:</p> <ul> <li>You won't get very far in a complex model without lazy loading, except your database fits into RAM or you don't mind to cut you OO model into pieces which destroys both maintainability and performance.</li> <li>You can have entities without virtual members when you use interfaces to create proxies from. However, you should only use these interfaces to reference to entities, because they could always be proxies.</li> </ul> |
20,237,959 | 0 | <p>Firstly, the cast to <code>int</code> is counter productive. You have <code>float</code> values and don't want to loose precision by casting to <code>int</code>, which will always be one of <code>{0, 1 ... 4 * radius^2}</code>.</p> <p>Furthermore, the comparison to <code>== 0</code> needs some luck to be hit. If you want to fill the circle, use <code><= 0</code> or if you want to draw a line try something like <code>abs(...) <= epsilon</code> where epsilon is some small number that describes the line's thickness.</p> <p>Be aware that you just set the r-component of the returned color of 1. This does not need to result in a red circle (e.g. if you already have a white texture).</p> <p>I would do something like the following:</p> <pre><code>float4 PixelShaderFunction(float2 coords: TEXCOORD0) : COLOR0 { float dx = coords.x - 0.5f; float dy = coords.y - 0.5f; if(dx * dx + dy * dy <= 0.25f) return float4(1.0f, 0.0f, 0.0f, 1.0f); else return float4(0.0f, 0.0f, 0.0f, 0.0f); } </code></pre> <p>Notice that you don't need an explicit radius or center because the texture coordinates are normalized.</p> |

2,907,939 | 0 | Hex characters in varchar() is actually ascii. Need to decode it <p>This is such an edge-case of a question, I'd be surprised if there is an easy way to do this.</p> <p>I have a MS SQL DB with a field of type varchar(255). It contains a hex string which is actually a Guid when you decode it using an ascii decoder. I know that sounds REALLY weird but here's an example:</p> <p>The contents of the field: "38353334373838622D393030302D343732392D383436622D383161336634396339663931"</p> <p>What it actually represents: "8534788b-9000-4729-846b-81a3f49c9f91"</p> <p>I need a way to decode this, and just change the contents of the field to the actual guid it represents. I need to do this in T-SQL, I cannot use .Net (which if I could, that is remarkably simple).</p> <p><strong>UPDATE</strong>: Some people have responded with ways that may work in one-off statements, I need a way to put this into an UPDATE statement.</p> <p>For example: UPDATE MyTable SET MyField = MyFunction(MyField)</p> <p>Where MyFunction is the correct answer to this question.</p> |
4,010,440 | 0 | <h1>Update</h1> <p>First off I'd suggest you drop the use of setInterval, they're particularly problematic. Instead use the <code>Timer</code> class, which is far more straightforward to manage and use.</p> <p>The <code>setInterval</code> inside the <code>sRes.onLoad</code> function is probably your issue though.

4,260,127 | 0 | Something confusing about digital certificates <p>A digital certificate is a digital document that certifies that a certain public key is owned by a particular user. Thus if you trust the CA that signed the certificate <code>C</code>, then you can trust that specific public/private key pair is owned by the owner of certificate <code>C</code>.</p> <p>a) Assume client <code>A</code> wants to establish a connection with server <code>B</code> located at url www.some_domain.com. When establishing a connection with <code>B</code>, <code>A</code> may receive from the other end a X.509 certificate <code>C</code> and a public key, belonging to the owner of certificate <code>C</code>. </p> <p>But how can client know that owner of <code>C</code> is really a server <code>B</code> and not some other entity that hijacked ( if that is the correct term ) the connection and sent its own certificate and public key to <code>A</code>? </p> <p>Only way I can think of for client to know whether owner of <code>C</code> is really <code>B</code>, is if <code>C's Subject</code> field also specifies the domain for which this certificate is valid or if it specifies the organization to which this certificate belongs ( but that only helps if client knows to which organization www.some_domain.com belongs )?! </p> <p>thank you</p> |

30,050,589 | 0 | <p>The problem is that you're producing this JavaScript inside the <code>onclick</code>:</p> <pre><code>alert_box(10,hello,134) </code></pre> <p>As you can see, you're trying to use a <em>variable</em> called <code>hello</code> there, you aren't using the string <code>'hello'</code>.</p> <p>To do so, you must put it in quotes. To do it reliably, you need to ensure that <code>"</code> and <code>&</code> in them are replaced with HTML entities (<code>&quot;</code>, <code>&amp</code>), and ensure that if they have <code>'</code> in them, they're escaped with backslashes. You'll probably also want to convert line breaks in teh string (if there are any) into <code>\\n</code> sequences and so on. It's a real pain, basically. (This advice assumes you'll continue to use <code>"</code> as the quote around the attribute and that you'll use <code>'</code> as the quote around the JavaScript string.)</p> <p>So:</p> <pre><code>var value_1 = 10; var value_2 = 'hello'; var value_3 = 134; $('#Blocks' + IJ).append( '<span onclick="alert_box(' + value_1 + ',\'' + value_2.replace(/&/g, "&amp;").replace(/"/g, "&quot;").replace(/'/g, "\\'").replace(/[\r\n]+/g, '\\n') + '\',' + value_3 + ')"></span>' ); function alert_box(a, b, c) { alert(c); } </code></pre> <p><strong>Live Example:</strong></p> <p><div class="snippet" data-lang="js" data-hide="true"> <div class="snippet-code snippet-currently-hidden"> <pre class="snippet-code-js lang-js prettyprint-override"><code>var value_1 = 10; var value_2 = 'hello'; var value_3 = 134; var IJ = 1; $('#Blocks' + IJ).append( '<span onclick="alert_box(' + value_1 + ',\'' + value_2.replace(/&/g, "&amp;").replace(/"/g, "&quot;").replace(/'/g, "\\'").replace(/[\r\n]+/g, '\\n') + '\',' + value_3 + ')">click me</span>' ); function alert_box(a, b, c) { alert("a = " + a + ", b = " + b + ", c = " + c); }</code></pre> <pre class="snippet-code-html lang-html prettyprint-override"><code><div id="Blocks1"></div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script></code></pre> </div> </div> </p> <hr> <p><strong><em>But</em></strong>, it would be <strong>much</strong> better not to use <code>onclick</code> at all, which bypasses all of those hassles:</p> <pre><code>var value_1 = 10; var value_2 = 'hello'; var value_3 = 134; $("<span>") .on("click", function() { alert_box(value_1, value_2, value_3); }) .appendTo('#Blocks' + IJ); function alert_box(a, b, c) { alert(c); } </code></pre> <p><strong>Live Example</strong>:</p> <p><div class="snippet" data-lang="js" data-hide="true"> <div class="snippet-code snippet-currently-hidden"> <pre class="snippet-code-js lang-js prettyprint-override"><code>var value_1 = 10; var value_2 = 'hello'; var value_3 = 134; var IJ = 1; $("<span>") .text("click me") .on("click", function() { alert_box(value_1, value_2, value_3); }) .appendTo('#Blocks' + IJ); function alert_box(a, b, c) { alert("a = " + a + ", b = " + b + ", c = " + c); }</code></pre> <pre class="snippet-code-html lang-html prettyprint-override"><code><div id="Blocks1"></div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script></code></pre> </div> </div> </p> <hr> <p>The above assumes that the values of <code>value_1</code>, <code>value_2</code>, and <code>value_3</code> don't change after you've hooked up the handler.
