For the last few days I’ve been working on a few improvements for the SSPS. One of the focus I have at the moment is to make it easier to use. The fact that it relies on a 3rd party component to work may raise eyebrows on some users. Hence I am trying to make it easier to setup a new repository. Today I pushed a few patches to the master that allow a user to configure a repository by using the following command:
sdm install --remote -a http://www.orpiske.net/ssps/files/0.1.x/adm/jackrabbit-2.4.2.xml
This command downloads, installs and pre-configure JackRabbit with a very simple repository. As the application matures, I plan to make its usage even easier. If you’re not afraid of unstable software, you can get the latest and greatest code from my github.
I switched from MacPorts to Homebrew. As far as I can tell, I am not coming back :). Here’s some goodies for you:
Are you tired of manually deploying your software? Please check the Simple Software Publication System. It’s still in development, but it already is able to help me.
One of the things I love most about Ubuntu is how easy it is to install software. Ubuntu’s PPA plays a great deal on this. So, here’s a small list of my preferred PPAs:
George Dumitrescu: indicator workspaces
MyUnity: well, for MyUnity
Peter Hurley: for Evolution Exchange Web Services (aka, evolution-ews).
Adding these PPAs to your system is as easy as running ‘sudo add-apt-repository ppa:<ppa-address>’
In WebSphere MQ 7, IBM has changed the default Coded Character Set Identifier (CCSID) and that may cause problems in certain conditions. I’ve encountered this problem while working on a Java application that used JMS to communicate with a legacy C/C++ application running on HP-UX. While the communication with other Java/JMS applications worked flawlessy, the communication with its non-JMS backed caused it to throw the MQRC_NOT_CONVERTED (reason code 2119) to be thrown.
This exception occurs because the queue manager failed to convert between different CCSIDs. Luckily, the problem is documented with great detail by IBM, along with several ways to resolve it. I’ve found that the easiest way to resolve the problem is by setting the following parameters during the JVM startup (you can replace 819 with target CCSID):
This solution, however, requires the application where the exception is thrown, to be running at least version 188.8.131.52.
I have just found my definitive guide for setting up read/write NTFS on Mac OS X Lion. It’s available here.
This is a collection of links that I took fry my old blog (in Portuguese):

A friend of mine, who read the first article, asked me to elaborate further about good logging practices. Hence, I decide to go over some of them, point the problems and discuss the alternatives. I will try to discuss the items in the order they appeared on the article. To start this series of texts, let’s discuss about fancy logs.

Given how easy is to log your application flow these days, it comes as no surprise that many developers abuse and misuse them. There are many anti-patterns that can be applied to logging and this article tries to help you avoid some of them.
