Just a quick note in case there is anyone else out there struggling to setup openwrt's Kamikazi dnsmasq server to hand out a default gateway and dns server other than the default. In the old days it was easy enough to just edit the dnsmasq.conf file but with Kamikazi you will want to edit the /etc/config/dhcp file to change default options.
More times than I care to mention I find myself having to battle with libvirt taking over my iptables rules and starting its own instance of dnsmasq, which just ends up ruining my whole day. Libvirt is a great abstraction layer for virtualisation, and although its xml config format and command line interface are well documented, how it works under the hood is less so.
Recently I got a new HTC Desire, the Google phone or Nexus One, in the rest of the world. I was faced with the perennial problem of getting my contacts off the old phone that had been in service for 3-4 years and onto the Android device. There was no easy way to do this, especially since I run Ubuntu. Luckily I am a JME developer and soon verified that the Nokia E70 supported JSR75, which allows for access to the mobile phones address book, and the ability to write files to local storage on the phone.
Jumping Bean is happy to announce the release of Calamari, a squid log file analyser application. The application has been released under the GNU Public License V3. Calamari consists of two components, a JavaFX front-end and a Java based back-end web service. It is designed to allow system administrators to easily identify anomalous events and drill down into the detailed log entries.
When ever I need to use the JAXB maven plugin, it is always a task to configure the maven pom.xml file to get this tool to run, but usually an answer can be found pretty quickly so its just annoying. Most often I just use javaws and jaxb plugins to import and export web services, but recently I had to export XML schemas for some POJOs for a client, and this was a bit more of a challenge. It seems, from the google search results at least, that Java developers do not export XML schema definitons for POJO's that often.
I have been working on a project recently which required the migration of a non-trivial application from a, circa 2000, web application built on Struts and JDBC, to a more modern layered architecture using Java Persistence API (JPA), the Spring framework and Wicket for the front-end. Rather than rewrite everything at once the client opted for a phased approach.
Sometimes software can be like the fashion industry, with ISV (independent software vendors) chasing the next best solution to the same old problems. A few years ago Scalix was all the rage in the mail server space, and lots of vendors jumped on the bandwagon telling their customer how much they could save by switching from Microsoft Exchange to Scalix.
Although bash is a powerful scripting environment it is a bit deficient, compare to other scripting languages, when it comes to date/time calculations. There are no convenient, generally available, date functions such as datediff or overloaded operators for mathematically manipulating dates and time.
A couple of months ago Scalix released "Scalix Active Sync" that allows customers using Scalix mail servers for their enterprise email requirements, to synchronise their mail and contact information with Outlook, or any other mail client that works with Scalix, and their cell phone!
This weekend I dived back into JavaFX again. JavaFX 1.2 has been out for a while now, and I have wanted to try out JavaFX again, ever since I took 1.0 for a spin about a year ago. At that time there was no support for JavaFX on Linux. This, combined with the fact that it JavaFX had no UI controls for data input, meant that I had no practical use for it since I am not really a visual designer but more of an application developer. Luckily now ,JavaFX runs officially on Linux, and whats more 1.2 introduced the first version of the charting API, somethings that worth looking at!
