Windows 7 on a Lenovo Ideapad S10e Netbook
At the end of January I ordered a nice shiny Lenovo Ideapad S10e from Buy.com. I managed to get a decent price that didn’t hurt the pocketbook, and it was a new toy that I could endlessly experiment with. I started to install a wide variety of operating systems to check for support and to [...]

Sunday, February 1, 2009
Lets face it, some sectors just can’t move to Linux due to legacy application support, lack of personnel support, employee training, and especially due to the jump in vastly different user interfaces. Each company has their own incredibly (insert sarcasm) unique reason for holding back. So, what is left for the network admins to do [...]

Saturday, January 31, 2009
Has your SOHO server been seeing a lot of failed ssh attempts from ipaddresses unknown to you? If so, you might be suffering from a brute force attack. These types of attack attempt to break into your box by trying to guess usernames and passwords. They are typically run on zombified computers from all [...]

Friday, January 30, 2009
I’ve recently ran across a unique little backup utility called Mephisto. The program is a command line tool written in Java that incorporates rsync and tar to do filesystem backups to a remote filesystem or local image. Of course utilities like this are great for doing system duplication, and especially great when you roll your [...]

Tuesday, January 27, 2009
You might have noticed that VirtualBox 2.1.2 has been released into the wild. While there is a laundry list of changes, a few performance and stability enhancements for Mac OS X were on the top of want my list.
While Parallels and VMWare offer commercial solutions, Sun backed VirtualBox offers many similar features for free. As [...]
Beginners Guide to Quick File Listing Using Ruby
Sunday, January 25, 2009
As a beginner to the Ruby language, I often found myself needing feedback listing which files are in a given directory. Ruby, for that reason alone, has been a quick savior. A couple of Google searches on this topic will land you somewhere near the Ruby class Dir. Dir is a part of the [...]

Tuesday, January 20, 2009
I recently ran across an interesting application that allows unprivileged users to install programs. While this maybe a good surface idea, the concept and coolness factor runs a little deeper.
The idea behind 0Install is to give the ’standard user’ install privileges without compromising a system if malicious software is installed. While this is cool [...]
QT 4.5 as LGPL
Tuesday, January 20, 2009
If you haven’t heard yet, there is good news on the application development platform front. Recently Qt Software, owned by Nokia, announced that the next version of their flagship product, QT 4.5, will be distributed under the LGPL. Prior to this announcement, the platform was free for open source use, while the price of a [...]

Sunday, January 4, 2009
It has been a while since I’ve had a chance to play with Ruby, and with 1.9.1 coming out in January I figured I’d go ahead and install 1.9 to get a feel.
Since speed was always an issue in 1.8 I figured I’d re-run my fib.rb script to find the fibonacci number for 35. [...]
Develop using the Play! Framework: The JPA Model
Sunday, January 4, 2009
A couple weeks ago I wrote an article on a fantastic framework called Play!. I want to revisit the project I created with the framework and introduce one of the coolest features that Play! has to offer: the use of Persistence through their JPAModel. I’m going to modify the CarLot application (Download ZIP) to [...]

Wednesday, December 17, 2008
Not too long ago I posted an article on the Play! framework. The framework has some promising features that really helps develop web applications in Java. To show how easy it is to use, I wanted to demonstrate with an example.
Update #1: Since the article posting there have been a couple of suggestions for [...]

Using enterprise backed Java with a Rails-esque feel, the Play! framework seems to offer quite a bit over traditional web development tools with its straightforward development environment and ease of deploying.
