13,222,849 | 0 | NodeJS+Sequelize+Jade; Using the hasMany collection on an object <p>I'm working on a nodejs+sequelize+jade web-app to learn nodejs. Everything basic is quite clear but now I want to up the ante. I have object(table) called brand. The object product has a one-to-many relation with brand. What I like to do is to findAll brands and show them in a Jade-template and also list the products under it.</p> <p>Here is some basic code</p> <pre><code>var Brand = sequelize.import(application_root + "/models/brand.js"); var Product = sequelize.import(application_root + "/models/product.js"); Brand.hasMany(Product, { as: 'Products', foreignKey: 'brand'}); Product.belongsTo(Brand, { foreignKey: 'key'}); </code></pre> <p>In the route for showing the brands and products I do;</p> <pre><code> Brand.findAll().error(errorHandler).success(function(brands) { brands[0].getProducts().success(function(products) { brands[0].products = products; }); res.render('listOfbrands.jade', { title: 'List of brands', items: brands}); }); </code></pre> <p>The strangest thing is that I can see a query being fired when the console.log has been executed but it doesn't create a correct query with the primary key of the brand. The query being select * from products where "brand" is null </p> <p>Also I want to know if I'm assigning the sub collection correct to access it in my Jade template by doing like this</p> <pre><code>ul each item in items li(class='brandItem')= item.name ul each product in item.products li=product.name </code></pre> |

From [6.5.9] of the C99 standard (emphasis mine):</p> <blockquote> <p><strong>Two pointers compare equal if and only if</strong> both are null pointers, <strong>both are pointers to the same</strong> object (including a pointer to an object and a subobject at its beginning) or <strong>function</strong>, both are pointers to one past the last element of the same array object, or one is a pointer to one past the end of one array object and the other is a pointer to the start of a different array object that happens to immediately follow the first array object in the address space.</p> </blockquote> |
21,984,294 | 0 | <p>I'm no expert in ActiveMQ, but I'm one of the developers of the HiveMQ MQTT broker, which is also written in Java. We have an OpenSource Plugin SDK, which allows to customize the authentication of clients and the authorization of clients to publish/subscribe to the broker. You can use a relational database or any other kind of service that is accessable from within Java to determine if a certain client is allowed to publish or subscribe to a topic. Clients can be restricted by topic, activity (publish/subscribe) and QoS.</p> <p>More information how it works can be found in the HiveMQ Plugin developers guide [1] [2].</p> <p>Cheers, Chris</p> <p>[1] <a href="http://www.hivemq.com/docs/plugins/1.4.0/#auth-permission-chapter" rel="nofollow">http://www.hivemq.com/docs/plugins/1.4.0/#auth-permission-chapter</a></p> <p>[2] <a href="http://www.hivemq.com/docs/plugins/1.4.0/#client-authorization-chapter" rel="nofollow">http://www.hivemq.com/docs/plugins/1.4.0/#client-authorization-chapter</a></p> |

30,921,360 | 1 | Creating graph vertices from numpy array <p>I have a numpy array full of values that I would like to create vertices from for every point in the array. I am using networkx as my graphing support method(documentation here: <a href="http://networkx.github.io/documentation/latest/tutorial/" rel="nofollow">http://networkx.github.io/documentation/latest/tutorial/</a> )</p> <p>I would like to treat each element within the array as a pixel location and create a vertex instance at each location. This is easy using a simple for loop:</p> <pre><code>new=np.arange(16) gnew=nx.Graph() for x in new: if new[x]>0: gnew.add_node(x) h=gnew.number_of_nodes() print h </code></pre> <p>And as expected, 15 nodes will be printed. However, this becomes more tricky when you have identical values. For example:</p> <pre><code>new=np.ones(16) gnew=nx.Graph() for x in new: if new[x]>0: gnew.add_node(x) h=gnew.number_of_nodes() print h </code></pre> <p>Now, because all values are identical-(1), only one node will be added to the graph. Is there a way to circumnavigate this?</p> |

25,342,573 | 0 | RESTful API to safeguard server and client from large datasets <p>I am working on designing a RESTful API and need second opinion on the design. I will be abstracting away the problem statement for better understanding.</p> <p>Consider a URI <code>/search?key1=value1&key2=value2</code>, which can potentially return a huge result set for a given search criteria for key1 and key2. </p> <p>My mandate is to make sure that the server and client are bounded by limits to prevent performance degradation. If that limit is reached and the intended data is not found in result set, user will be asked to refine the search query to narrow down. (I am not thinking of pagination, that is for a different problem set)</p> <p>Approach is to allow client specify a limit to server that it(client) can comfortably handle, and to help server set a limit for itself to prevent from generating huge result sets affecting performance.</p> <p>Client can do <code>/search?key1=value1&key2=value2&maxresults=xxxx</code> to specify it's limit.</p> <p>Server can set it's own limit as a configuration param for search URI. While serving a request, server will take a min of (client's limit, server's limit) and generate result set satisfying the effective limit.</p> <p>The JSON generated will have a meta data part which will mention if the result was truncated or not, and the effective limit set. The client can inspect this part and ask the user to refine search if "truncated" is "true".

The former uses eta-expansion, which fails for the aforementioned reasons. With <code>future.map(x => from(x))</code>, there is no eta-expansion happening. Instead, you have an anonymous function that simply <em>calls</em> <code>from</code> instead of eta-expanding it. Therefore, the compiler can infer the type of <code>x</code>, which tells us that <code>x</code> is a <code>C1</code> (in this case), and it can find the implicit conversion <code>c1ToC2</code> that satisfies the type parameters of <code>from</code> while resolving the implicit and the final return type of the method, <code>Future[C2]</code>.</p> |

10,133,796 | 0 | <p>You can override <code>-[NSView viewWillMoveToSuperview:]</code> in a custom NSView subclass. This is simply a means for your class to be notified when its position in the view hierarchy is about to change. It doesn't have some deeper meaning other than what its name implies, but you can, of course, harness it to serve various purposes. It's not a method on a delegate or on the view controller, but you can implement such delegation yourself if you want.</p> <p>Also, if your code is moving views around the view hierarchy, it can directly do whatever it wants immediately beforehand, which is also roughly when such a method would be called.</p> |
