Are you having problems getting Bart’s Boot CD to recognize the Broadcom NetXtreme 57xx Gigabit Controller network interface card?
I work with some Dell computers (models: Optiplex SX280, Optiplex GX620, Precision 690 and Precision 370) that have this NIC and the current version of Bart’s Boot CD is unable to recognize it. The automatic NIC detection fails with a message to the effect of “could not find any device, you can try manually selecting a driver” (sorry, I can’t remember the exact error). …Continue reading » Bart's Boot CD with Broadcom NetXtreme 57XX Gigabit Controller

First and foremost, I am a persistence layer software developer. I don’t do much UI work and what little UI work I do usually involves rich client UIs. I rarely do any web UI work.
Having said that, I think it’s important to know at least a little bit about web UI technologies, even if you are a back-end developer. Why? Well, at the very least, you will be able to understand the vocabulary of the UI guys you work with. Furthermore, you never know when you might have to look for a new job and there’s a good chance they’ll want you to know about some of that web UI stuff.
With that in mind, I recently picked up a copy of Head First HTML with CSS and XHTML to see if I could learn a thing or two. I just finished the book and I wanted to share my thoughts on it. …Continue reading » Book Review: Head First HTML with CSS and XHTML
Today I had to copy a really big file (in this case, a Ghost image) from a Linux box to a Windows box, using Samba. My first instinct was to use the cp command. The problem with cp is that it does not show you any sort of progress (I couldn’t find any relevant option in the cp man page). What I wanted was a progress bar display like the one wget displays.
I did some googling and found a few decent candidates: …Continue reading » How to Copy a File and Get a Progress Bar, in Linux
In my software development job, I do a lot of persistence layer implementation, especially using the Hibernate O/R mapper. I work closely with a clever domain layer programmer who tends to use a lot of design patterns, perhaps because he likes the woman of the cover of Head First Design Patterns.
Sometimes, these design patterns create a bit of a challenge for me in the persistence layer, especially since I always tell my domain layer programmer that I can persist things transparently, without having to muck up his code with persistence layer artifacts.
A case in point is the State pattern. I have now persisted 5 different sets of states so it’s no longer a challenge. However, it took me a little while to figure how to do it. Naturally, I started by checking out Hibernate’s forums but much to my chagrin, I found several people asking the same question but no one offering an answer. Therefore, I will provide an answer in this blog post. …Continue reading » State Pattern Persistence with Hibernate
