Unsafe Jan 21 st 2012 Comments Not sure how long ago I started using OSGi . Perhaps it was 12 months ago or then perhaps 18. And yet I still find it painful using OSGi especially every time I bring in a foreign set of jars into the ecosystem . And yet I continue to be a dogged proponent . Hereâ s . why First let us understand one of the many problems OSGi solves . Let us imagine your java application has exactly three classes . One is the class you wrote called âMy.javaâ bundled in a jar called âmy.jarâ . Another is a class called âUses.javaâ whose api and features are leveraged by âMy.javaâ and is

K . Scott Allen Experiments In Writing Home A Simpler MapReduce with MongoDB and C Continuing from the previous post about MapReduce with MongoDB we can clean up the code a bit using an extension method that takes a single string parameter . var db server.GetDatabase( mytest var collection db.GetCollection( movies var results collection.MapReduce( CategorySummary foreach var result in results.GetResults( Console WriteLine(result.ToJson( The code no longer needs to embed JavaScript into the C code , or specify the map reduce options . Instead , the CategorySummary parameter tells the extension method everything it needs to know . First , it can load the map , reduce , and finalize functions from JavaScript files on the file system using the parameter to build the path to the files . Keeping

K . Scott Allen Experiments In Writing Home Custom Slider Value Display with jQuery UI The jQuery UI slider widget doesn't display it's current value by default . However , you can tap into the slide event and grab the current value from the second parameter passed to the event handler . The second parameter in a jQuery UI event handler is typically named ui and always contains some useful information about the state of the . widget function var ageInput ageInput var ageDisplay ageInput div var updateSliderValue function event , ui ageDisplay.text(ui.value ageInput.slider({ min : 0, max : 122, slide : updateSliderValue You can also position the display of the value above the slider handle thumb . The DOM element representing the slider thumb is passed in the ui parameter as the handle

When I wrote my summary of the conference, I forgot something very important: you can download nearly all of the Clojure/West 2012 presentations from github. Some of the files are quite large so you may not be able to simply view the raw PDF on github - you will probably have to clone the repo locally.

K . Scott Allen Experiments In Writing Home Readable DOM Ready Event Handlers One reason some people don't like JavaScript , I think , is because idiomatic JavaScript favors fewer keystrokes and CPU cycles over readability . There is a large amount of script code that is hard to read , and even harder to maintain and change . Take , for example , the following snippet . I think this represents a typical DOM ready event handler with jQuery . function warning dialog({ autoOpen : true openDialog click( function warning dialog( open submit click( function warning dialog( close names autocomplete({ source : Foo Bar Baz It's a wall of text written in the get in , get done , and get out style . The code requires some concentration to see what is happening inside . I think the code improves after

The training course was a bit of a firehose and during one of the conference sessions , my colleague asked me whether he was supposed to understand these mostly very advanced talks . The conj is an inspiring event : a single track of sessions that cover the leading edge of work in the Clojure community , philosophical

K . Scott Allen Experiments In Writing Home Cool Down with Canvas and JavaScript The idea is to use an image as a command button When the user clicks on the image , the image greys out and acts disabled for a period of time . The image slowly transitions back to an enabled state by letting color sweep around itself in a clock-like manner . There are hundreds of approaches you could use to implement the effect . My initial attempt used a single image and pixel manipulation in a canvas . I need to give credit to David Catuhe blog deltakosh for giving me the idea of using two images and a canvas . One image has color , and one image is in black and white . Selectively drawing the images into a canvas element can achieve the smooth World of Warcraft cool down effect , and the code is simple .

K . Scott Allen Experiments In Writing Home Yet Another Bundling Approach for MVC 4 ASP.NET MVC 4 allows you to bundle multiple JavaScript or CSS files into a single bundled download , and optionally minify the bundle to reduce the download size . John Peterson has a good introduction to the feature . I've been experimenting with an approach that lets me use the following code during application startup . BundleTable Bundles.Add( new RGraphBundle The RGraphBundle class lists all the JavaScript files needed for a certain feature , and sets the virtual path to reach the bundle . public class RGraphBundle JsBundle public RGraphBundle( base Rgraph AddFiles( Scripts Rgraph RGraph.common.core.js Scripts Rgraph RGraph.common.context.js Scripts Rgraph RGraph.common.zoom.js Scripts Rgraph
