lazy-loading

First time loading remote images into an iPhone app, and would like some help optimizing the process. What I've currently done is get the image if it doesn't exist, and cache it. The major goals are to: only load images when needed. save images for future use to reduce data consumption, and allow the user to have a somewhat functional app when not connected to the internet. I just don't think I'm doing it well enough. Here's a snippet of the code within tableView:cellForRowAtIndexPath: MVImageCell * cell = (MVImageCell *)[tableView dequeueReusableCellWithIdentifier:@"PicsAndVideosCell"]; //

I know there are plugins to lazy load images. I have a coupon code site, on my category page for shoes in my DB I have 500 coupons that match. I don't want to display all 500 for obvious reasons. I only want to show 20 initially, and then as the user keeps scrolling down the page it loads more coupons. How would I go about doing this? EDIT: I've got the ajax call working. Here is the code I'm using: <script type="text/javascript"> $(window).scroll(function(){ if ($(window).scrollTop() >= $(document).height() - $(window).height() - 10) { $('div#loadmoreajaxloader').show(); $.ajax({ url:

The normal result() method described in the documentation appears to load all records immediately. My application needs to load about 30,000 rows, and one at a time, submit them to a third-party search index API. Obviously loading everything into memory at once doesn't work well (errors out because of too much memory). So my question is, how can I achieve the effect of the conventional MySQLi API method, in which you load one row at a time in a loop? Here is something you can do. while ($row = $result->_fetch_object()) { $data = array( 'id' => $row->id 'some_value' => $row->some_field_name );

I have such kind of @OneToOne Hibernate relationShip public class Address implements Serializable { private String id; private String city; private String country; //setter getters ommitted } public class Student implements Serializable { private String id; private String firstName; private String lastName; private Address address; } address Item is mapped as LAZY. Now I want to fetch user and it's address using session.load(Student.class,id); In my daoService. Then I return it as JSON from my Spring MVC controller: @RequestMapping(value="/getStudent.do",method=RequestMethod.POST)

I've been coming across blogs/websites lately that only load images when they are scrolled into the visible viewport. It then fades them in. Is there a jQuery ... even Wordpress plug-in that does this? e.g. http://icodeblog.com Galen One of the good things about JavaScript is you can view source and look at whats going on. After viewing the source I found this: http://www.appelsiini.net/projects/lazyload LazyReady: http://plugins.jquery.com/project/LazyReady You can try this jQuery plugin I wrote that uses html comments to lazy load any arbitrary bits of html, including images: jQuery Lazy

In the last couple of days I have tried to make support for XML marshalling/unmarshalling of a Hibernate model, using MOXy JAXB. Trying to do this, I have run into a problem with hibernates proxy objects. Consider something like: public class User { @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "address") public Address getAddress() { return address; } } public abstract class Address { // Something } public class CoolAddress extends Address { public String getSomething() { return something; } } I have tried to map this code using MOXy JAXB in the following way: @XmlAccessorType

I'm building a 4 layered ASP.Net web application. The layers are: Data Layer Entity Layer Business Layer UI Layer The entity layer has my data model classes and is built from my entity data model (edmx file) in the datalayer using T4 templates (POCO). The entity layer is referenced in all other layers. My data layer has a class called SourceKeyRepository which has a function like so: public IEnumerable<SourceKey> Get(SourceKey sk) { using (dmc = new DataModelContainer()) { var query = from SourceKey in dmc.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in
