So now that we have covered some of the theoretical parts, we can start to put our knowledge of the data model and sorting behavior to some use. In this blog post i will start to explain how you can configure your ColumnFamilies, make a connection to the database and… Read more >

The last time we talked about the various containers that are present within the Cassandra data model (for example, column, super column, column family, etc..). One part we didn’t talk about is the the sorting behavior. Unlike normal relational databases Cassandra has no capability of querying so you are not able to specify sorting when you retrieve data.

By default Cassandra sorts the data as soon as you store it in… Read more >

In the old days, well old, in the time when we were still using Cassandra 0.5.x it was a bit more work to install Cassandra then now-a-days.. with the current release of 0.6.4 it is as easy as a winds breeze. This has been the case since the last few versions and has led me to rewrite this part completely. A… Read more >

iSpectrum is a plug-in for Eclipse which enables you to develop iPhone applications in Java. They provide a library which contains Java counterparts of the Objective-C classes. It doesn’t require a JVM to run since the Java code is compiled in Objective-C code, which is compiled in native code with Apple iPhone SDK.

It even allows you to debug the iPhone application using the Eclipse debugger, some other nice features include a automated Java garbage collector, so no more retains and releases.

Personally i haven’t tried it yet so i cannot tell how far they are with compatibility of all the various iPhone libraries but from what i can tell they are doing are nice job. The core Java classes are based principally on Android, and the compiled result should almost feel like native (according to iSpectrum).

The system requirements are at least Windows XP (32-bit) or Vista (32- or… Read more >
