IBM has donated Cloudscape, an embedded relational Java database that has been in active development since 1996, to the Apache project, where it will be called Apache Derby.

There's a Cloudscape tutorial site on IBM DeveloperWorks and an Apache Incubator site where it can be downloaded.

Karl Rove Advertises Liberally

As a Florida resident, I can't go a half hour without seeing an ad in which "John Kerry and the liberals in Congress" are plotting some form of progressive deviltry, such as raising taxes on assault rifles to protect the abortion rights of gay whales.

The ads are especially pervasive during major sports events:

Last night while Niki and I were trying to watch the baseball playoffs, every other commercial was a political attack ad. ... One ad they played over and over again all night on every channel starts every sentence for the first half of the ad with "John Kerry and the liberals in Congress ... John Kerry and the liberals in Congress ..." Shut the hell up and let me watch baseball in peace before it goes away again until next Spring! Don't Clockwork-Orange me into an aversion to baseball!

I'm outside the target audience of these ads, but that phrase doesn't seem like one of Karl Rove's better pieces of gopaganda. It positions John Kerry and the liberals in Congress as two distinct groups, an impression that doesn't help the effort to paint him as the second coming of Eugene Debs.

Using Your Header in UltraEdit

Since I began using UltraEdit as a programming text editor recently, I lost the ability to call the header() function in PHP. Every time I tried it in a script, the following error happened: "Cannot modify header information - headers already sent."

This error happens whenever a script produces output before header() is called. When obvious causes for this problem have been ruled out, you must look for anything that might output a blank line or other characters.

In my case, UltraEdit put three characters at the beginning of a UTF-8 file without displaying them in the editor, so I didn't spot them until I opened one of the errant scripts in vi.

These characters are a byte-order marker, as described in the UltraEdit support forum, and here's how to turn this feature off:

1. Choose Advanced, Configuration. The General tab should be in the front.
2. Scroll down to the Load/Save/Conversions section.
3. Deselect the two Write UTF-8 checkboxes.

There's a possibility I've incurred the wrath of the Unicode gods by making this change, but at least my PHP scripts work.

Enjoy Some Steamed Rice

Anne Rice recently flipped out on Amazon.Com, writing an egomaniacal rant in response to customer reviews of Blood Canticle:

First off, let me say that this is addressed only to some of you, who have posted outrageously negative comments here, and not to all. You are interrogating this text from the wrong perspective. Indeed, you aren't even reading it. You are projecting your own limitations on it. And you are giving a whole new meaning to the words "wide readership." And you have strained my Dickensean principles to the max. I'm justifiably proud of being read by intellectual giants and waitresses in trailer parks, in fact, I love it, but who in the world are you?

Her personal assessment of the book: Five stars.

Get Your Browser War On

Writing for eWeek, columnist Jim Rapoza believes that Microsoft's XP-only security upgrade to Internet Explorer will send millions of users to other browsers, making the browser market competitive again:

For the first time in years, IE's market share has dropped slightly. But I predict that this trickle will soon become a full-fledged torrent.

In fact, I fully expect that, a year from now, IE's market share will be below 75 percent.

I've been using Firefox for a while, finding it vastly superior to Internet Explorer. The browser opens pages in new tabs rather than new windows, can bookmark all open pages with a single bookmark, and offers keyword shortcuts that can initiate searches on any site from the browser's address bar.

For example, I can type find Microsoft Bob to load a Google search results page for the text Microsoft Bob and info Sinclair Lewis to view pages related to the author on the InfoPlease reference site. A shortcut can be set up for any Web site where search terms appear in a page URL.

Don't Follow the Script

When his weblog moved in March, Michael Fioritto put JavaScript in the first item of his RSS feed to redirect visitors to his new site.

The news aggregator AmphetaDesk read the script tag and executed the redirect, making it impossible for me to use the software until I unsubscribed from his feed, which probably wasn't the effect he was going for.

An aggregator that doesn't strip out script and other dangerous tags is a security exploit waiting to happen.

Java 2 in 24 Hours Panned

Just read an old review by Pan Pantziarka shredding Sams Teach Yourself Java 2 in 24 Hours, my beginner's Java book last revised in 2002.

By the end of the book, assuming you haven't been stunned into a coma by the author's humor (yep, it's a US thang), you'll have a very superficial view of Java programming. What you won't have is the knowledge or the insight to produce anything useful.

Mommy.

This book, which has done well with new-to-Java novices, will occasionally receive a total ass-kicking at the hand of a professional coder like Pantziarka.

Without challenging his conclusion that my work sucks big rocks, I think that some coders misunderstand the target audience for a 24 Hours title.

My goal was to write a Java tutorial that could be tackled successfully by total beginners and people scared off the subject by the complexity of college courses and existing books. My imaginary target reader was a person who needed a moment to get his head around the concept of a multi-dimensional array.

You can't serve that audience without reducing to the language elements you believe are most crucial to understanding.

There are plenty of books that assume some level of comfort with basic programming concepts, but I didn't think that Java had a tutorial that could evoke an aspiring programmer's first "by George, I think I've got it!" experience.
