I want to write testable code and occasionally I bump into frameworks that make it challenging to unit test. Ideally I want to inject a service stub into my code then control the stub’s behavior based on my testing needs. Commons Http Client from Jakarta facilitates integration with HTTP services but how to easily unit… Continue reading Unit testing with Commons HttpClient library
In my constant search for free weather data for Spincloud, a short while ago I have found a gem: free forecast data offered by the progressive Norwegian Meteorologic Institute. The long range forecast coverage is fairly thorough and covers most more than 2700 locations worldwide. I am happy to announce that I have extended spincloud.com… Continue reading Spincloud, now with worldwide forecast
I admit that I regard automation as a dull but vital part in the success of a project. Automation had evolved into Continuous Integration, a powerful toolset allowing frequent and regular building and testing of the code. I won’t get into what CI is (check the internets). Instead, I am going to explore a couple… Continue reading Continuous everything?
Sep. 15 came and went and I didn’t realize that this blog is one year old. I didn’t post in the last few months but this is because I have been busy moving across the world from Toronto back to Europe (I’m in Berlin now), becoming a father (“the best job in the world”) and… Continue reading blog.newsplore.com is one year old!
It took a while since the previous feature update to Spincloud. I have done a number of upgrades to the underlying tech and some intensive code refactoring but nothing visible. The time has come for another eye candy: heat maps. It is a map overlay that shows a color-translated temperature layer based on interpolated values… Continue reading New Spincloud feature: heat map overlay
There are three forces that shape a project: domain, process and technology. Add the “-driven” suffix to any of them and you’ll perhaps recognize some of the methods used in projects you’ve been involved in and yet, as soon as one takes too much of a lead against the other two, failure will follow almost… Continue reading A project triumvirate
There’s an interesting story rippling the news stream these days: The New York Times is questioning the ways Techcrunch reports on news. The crux of the issue is product journalism v. process journalism, the act of producing news only after all facts have been verified versus just writing the story based on what the author… Continue reading Process Journalism really is Agile Journalism
In the first part I’ve left-off with some good news: successful deployment in the local GAE container. In this second part I’ll talk about the following: – Loading data and browsing – Table indexing – Limitations of datastore queries – More datastore limitations and JPA issues – Deployment – Performance – Production monitoring – Usage… Continue reading Reviewing Google AppEngine for Java (Part 2)
A short two months back I posted an article describing how to upgrade to Spring 3.0 M2. Spring folks are releasing at breakneck speed and so I got busy again upgrading spincloud.com to Spring 3.0 M3 released at the beginning of May. Just yesterday (June 3rd) the team released Spring Security 3.0 M1 and I… Continue reading Upgrading to Spring 3.0.0.M3 and Spring Security 3.0.0.M1
Level 2 cache is one of the most powerful features of the JPA spec. It’s a transparent layer that manages out-of-session data access and cranks-up the performance of the data access tier. To my knowledge it has been first seen in Hibernate and was later adopted by the then-emerging JPA spec (driven mostly by the… Continue reading Proposal to standardize the Level 2 query cache configuration in JPA 2.0
