I started the Google AdWords campaign last night. I'm using AdWords to supplement some of the searches where the www.devdaily.com site does not appear in the first page of search results. One example is when google users search for "unix example", the "www" site does not show up well for some reason. Therefore, I'm spending a little money to buy some exposure. Stay tuned for results...

Back to thinking about JLint ... there seems to be several implementations of this on the web. The one I downloaded is from artho.com. One thing that was not clear from the instructions was how to run this program. I *assumed* that I would point it at a source file, but I really needed to point it at a *class* file. Once I figured this out, running it became a simple matter of moving to the directory that contained the class files and typing this
Here are two links to Java/OOP and Unix training material I'm getting online as fast as possible:
- Free "Java and Object-Oriented Programming" training material
- Free "Introduction to Unix" training material
By the time this is all published in the next two weeks, it should be nearly 1,000 pages of online training material. Woo-hoo!
I saw this guy's page a long time ago, and don't want to forget about him again. The site is joelonsoftware. He seems to have some good stories on software dev.
The most amusing part of the last month or so in the tech industry has been the effort of SCO to sue IBM over their use/implementation of Linux. Here is a position paper by Eric Raymond regarding the lawsuit, on behalf of the Open Source Initiative. It should be noted that Raymond was a regular speaker at the SCO Forum for several years back in the 90s.
Here are a few notes from "my other life". Amazing what happens when I've actually gotten a little sleep. It's been this way since forever.
Here's the material from a seminar I've done several times on "Working Backwards with JUnit". The idea for this seminar came about from an article of the same name by several authors in the Extreme Programming blue book. I can't remember their names right now, but all of the credit goes to them for the idea, and I need to acknowledge them properly.
Java JTextField question: How do I right-align the text in a JTextField?
Long answer: I need to look at this some more to understand the difference between the alignment constants in SwingConstant and the alignment constants in JTextField.
Holy Microsoft Passport security flaws! Where do you want to trust your money today?
Ouch ... here's a quick little ditty on how to properly size a JDialog to fit the size of a wide/large JTable that it contains.
(From a recent email.) Help, I have a 13-column JTable, inside of a jscroll pane, inside of a borderlayout, inside a JDialog. Ideally, I would like the dialog to initially open up to the correct width needed to display the 13 columns without horizontal scrolling.
Setting the preferred width of each column (only) does not work very well. Setting the minWidth gets the columns to open up to the correct width, but then the last 7 or so columns fall off the right hand side of the dialog.
Java FAQ: Can you share some source code for a “Java wget” program, i.e., a Java program that works like the Unix wget or curl commands?
Here's the source for a program I've named JGet, which acts similar to the wget or curl programs. I didn't have wget installed when I needed it (and my client wouldn't let me install it), so I wrote this Java wget replacement program.
I have used GRASP in one context in this blog, but the GRASP I'm interested in today refers to Craig Larman's General Responsibility and Assignment Patterns. I saw those first referenced in Larman's book titled "Applying UML and Patterns". Larman's home page is one big page, but what the heck, he's a good author.
Don't know much about the following site, but it does contain an online version of a book titled Practical PostgreSQL.
Here's a little Java best practics info from someone named Ahmet Haliloglu. It's mostly on servlets and JDBC.
Probably the most interesting document I've found on user interface design is the PDF from this site, discussing Do's and don'ts of user interface design. The funny part is that the site itself is named "Civil Engineering with Computing: OOP with C++, UML, and the STL" ... but this page does not contain any type of HTML title. Goes to show that we're all human. :)
Note to me: Using
sendmail from the command line can be better than using the
/usr/lib/sendmail -t -f firstname.lastname@example.org -F "Al Alexander" < my_message.txt
This works very well if I put things like To:, Cc:, Reply-to:, etc, in the file named my_message.txt.
One of my co-workers pointed me to this site by Jeanette Winzenburg that discusses some issues regarding the Swing framework in the land of Java, including problems with the JTable.
