lazy-loading

I have been searching (unsuccessfully) for a reliable method to lazy load images while using the HTML5 spec for <picture> . Most solutions/plugins out there currently rely on using data- attributes. I could be wrong, but it doesn't seem this method will work in conjunction w/ <picture> . I'm really just looking to be pointed in the right direction. If anyone has a solution that they're currently using, I'd love to see. Thanks! UPDATE: Here is standard markup per the HTML5 spec: <picture width="500" height="500"> <source media="(min-width: 45em)" src="large.jpg"> <source media="(min-width: 18em

If I have access to an angular2 application's code and there is a module that is supposedly lazy loaded, is there a way, independent of examining the code, that I can test that module to see if it is lazy loaded. If necessary and there is no other way, I could add code into the module in question to test, if that is a possibility. But what code would I add? Check the Network tab of chrome dev tools (ctrl + shift + i) in the Google Chrome browser. If your module is not being lazy loaded you will see a row for the module in the network tab when the site first loads up. If it is being lazily

I have some 4500 entries in my database. What is the best way to show them in a ListView. Should I load them all in one stretch when the application initializes or should I use lazy loading? The list will also be searchable and filterable. Could you also point me to some nice articles that would gimme a better idea. Please do give me suggestions. I would like to point you to here first but I also have some experience I would like to share. First, showing anything more than say 500 items in a list is probably going to cause users to complain (maybe not though). Users can get overwhelmed with

I'm struggling with real-world use of JPA (Hibernate, EclipseLink, etc) in a Swing desktop application. JPA seems like a great idea, but relies on lazy loading for efficiency. Lazy loading requires the entity manager exist for the lifetime of the entity beans, and offers no control over what thread is used for loading or any way to do the loading in the background while the EDT gets on with other things. Accessing a property that happens to be lazily loaded on the EDT will block your app's UI on database access, without even the opportunity to set a busy cursor. If the app is running on wifi

I am currently using Jquery Lazy Load and I was wondering if there is a way of making a callback when all the images from my container ended loading (when lazy load has made all his magic). The reason for this is that I am using jScrollPane Plugin as well and I would like to call the jScrollPane reinitialize function. Thanks' Looking at the source, it seems that the lazy load plugin calls the settings.load function after loading an image passing the loaded image element and a couple of parameters: if (settings.load) { var elements_left = elements.length; settings.load.call(self, elements_left,

I was looking for ways to do lazy initialization and found Lazy<T> which is included in .NET 4. I was thinking of rolling my own implementation of Lazy<T> for .NET 3.5 (with a simpler multi-thread policy), and I bumped into the following problem: Lazy has basically two types of constructors: class Lazy<T> { public Lazy(){...} // ctor #1 which uses T's default constructor for creating an instance of T, and public Lazy(Func<T> func){...} // ctor #2 which lets the caller decide how the instance of T is created. Now here's the problem: If I want compile-time checking for the 1st ctor I will add a

Instead of using a table plugin by someone else, I choose to do it the standard HTML way of making Tables and rows etc etc. I would fetch data from a database to fill the rows. But when the number of rows exceeded 10,000, I realized I needed to lazy_load the rows otherwise the website would be incredibly slow. I've looked for ways to lazy load rows of a table, but I can't seem to find it anywhere, so my question is simply does the lazyloading plug-in or for rows even exist ? Hope some guru can answer this. Thanks in advance! Background as to what I'm trying to do: I'm creating the rough sketch
