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

Today saw the launch of a UK Government White Paper on Open Data. In his forward, Francis Maude writes :- “Data is the 21st century’s new raw material…” At EuroClojure this year I spoke about the numerous strengths of Clojure as an enabling technology to release trapped data and onto the web. I think this [...]

Another minor update, addressing JDBC-34 by adding a new :connection-uri option so you can specify a raw JDBC URL which is passed directly to the DriverManager class, and fixing a quoting bug when converting Clojure keywords to SQL entities (for example :a.b became [a.b] instead of [a].[b]).

I recently read a good article by Matt Aimonetti on creating web services. He makes some particular good points. Web APIs are increasingly exposing raw data “But web APIs are also more and more used to expose raw data to other software. The challenge though, is that we haven’t changed the way we write web [...]

K . Scott Allen Experiments In Writing Home Trouble , Trouble , A Quintuple of Double Parallel Work in Async MVC Actions One of the samples in the ASP.NET MVC 4 release notes is an example of using an async controller action . public async Task string city var newsService new NewsService( var sportsService new SportsService( return View( Common new PortalViewModel NewsHeadlines await newsService.GetHeadlinesAsync( SportsScores await sportsService.GetScoresAsync( At first glance , it might seem like getting the headlines and getting the sports scores are two operations that happen in parallel , but the way the code is structured this can’t happen . It’s easier to see if you add some async methods to the controller and watch the different threads at work in the debugger . public async Task

After completing the classes it’s now time for discussing about the interfaces in Dart.This is not at all a new term for folks coming from a OO background, interfaces are actually definition of the contract, or in more general defines the operations to be realized by the implementing classes.Apparently Dart interfaces are also quite same [...]

Thanx to John Whish (aliaspooryorik), DI/1 has a new singletonPattern option that allows you to specify which beans are singletons based on their name, regardless of the folder in which the CFC is found. See the DI/1 wiki for more information.

K . Scott Allen Experiments In Writing Home Evolution of the Entity Framework : Lesson 1 Many to Many Relationships with EF A many to many relationship is easy to setup with code first EF . For example , an Author can write many . books public class Author public virtual int Id get set public virtual string Name get set public virtual ICollection Book Books get set And a book can have many authors . public class Book public virtual int Id get set public virtual string Title get set public virtual ICollection Author Authors get set To start a library , all you need is a book set or author set or both in a DbContext derived class . public class LibraryDb DbContext public DbSet Book Books get set Then the framework will create a database schema with the join table you might expect .

They are a lovely group of people who work hard to make every attendee happy and comfortable . There were also 100 or so speakers in town who also worked hard to make every attendee happy and comfortable . This year’s NDC delivered over 200 hours of quality content .
