I came to know Hessian, the binary web service protocol. Some time ago I blogged about the same idea Predictable Binary Representation (PBR) , naively thinking that no one has done this before. With the help of few friends, and some googling ... http://noor.ojuba.org/2008/11/a-ride-with-hessian/ XML is nice, YAML and JSON are cool, proprietary formats for binary encapsulation are not good; those are all facts that many people agree to. But they all the good solutions remain sub-optimal when it comes to network bandwidth overhead and cpu usage needed to parse the blob every time. This might ... http://noor.ojuba.org/2008/09/predictable-binary-representation-pbr/ SQLite is a very interesting database engine. Its performance, simplicity and that fact it runs as a library (not a server) make it the perfect candidate for small project with few users. Today I experimented with accessing SQLite database from within groovy. I tried the SQLite JDBC libraries and all went fine. ... http://noor.ojuba.org/2008/07/groovy-with-sqlite/ I feel very strongly about the historical opportunity for the GNOME community to switch their tool kit over to QT 4.x.

I wonder. :) class Storage { List stack = [] synchronized void leftShift (value) { stack << value println "Push : $value" notifyAll() } synchronized Object pop() { while(stack.isEmpty()) { try { wait() } catch (e) {} } def value = stack.pop() println "Pop : $value" return value } } storage = new Storage() Thread.start { 10.times { storage << it sleep 100 } } Thread.start ... http://noor.ojuba.org/2008/07/weaving-groovy-threads/ Lots of fun with Groovy introspection. Java already provides something similar but in Groovy it has completely different taste and use. I actually use introspection often from within groovysh to investigate on what a class provides, just like auto-complete in modern IDE's :) // Whats is your class? a = 5 b = "Hello" println ... http://noor.ojuba.org/2008/07/groovy-introspection-know-what-you-have/ GORM is cool, but groovy Sql is for the simpler cases were you just need to interact with the database. groovy.sql.Sql is just an amazing Groovy class. See this link for a mind-opener level of ease when dealing with databases and this is an interesting article from IBM Developer works ... http://noor.ojuba.org/2008/07/databases-with-groovy/ Dynamic text templates are joy to do in groovy. I came across the need of such functionality many times during my past projects, and now with the new one. Not only can I place my bound variables and reuse them in the template, but I can also run legal groovy code. text = ... http://noor.ojuba.org/2008/07/groovy-simple-templates/ In the computer industry, the pendulum of debate, innovation, and building infrastructure at one end vs building up complete and ready solutions on the other end keeps swinging every 20 years (more or less). So here it comes, to the rest of the thinkers and planners and to the delight of ... http://noor.ojuba.org/2008/07/the-wars-are-over-let-the-era-of-peace-and-prosperty-begin/ Need a cool development setup for Groovy and Grails on Linux? No I don't mean Eclipse nor IntelliJ, and Yes, I'm smart enough for that I'm dumping the autocompletion and autoerror detection; at least I know i'm smarter than the current plugins for those two. :) Searching for a good development setup ... http://noor.ojuba.org/2008/06/gedit-with-groovy/ Groovlets, could be the coolest thing since sliced-bread ... except for the fact that it does n't seem to support fileupload! what? why? is there a solution?

This patch suggested changing code in groovy itself, which is ... http://noor.ojuba.org/2008/06/uploading-files-to-a-groovlet/ Groovelts and Groovy Server Pages are unbelievably simple to set-up and use, quick and dirty web-api's and proof of concept can be implemented in no time! Using groovy as a serverlet (also known as Groovlet) is a really cool thing. Grails is a must if you want to develop a complex ... http://noor.ojuba.org/2008/06/groovlets-setting-up/ Would the debate on the best Web-development framework evern end? probably not, becuase debate reflects the very nature of us humans. We see things from different angles, and apply them to different cases ... Nevertheless, for the yours truly this does not have to be the case... here is my angle ... http://noor.ojuba.org/2008/06/my-search-for-a-web-development-framework/ I never thought that I would have a blog, I am not a talking-kind-of-person.
