Metallica has a new album coming out. If you want to be a part of the epic making of this album, you can check out Mission: Metallica.
From metallica.com:
Mission: Metallica is your chance to be on the inside of the new album with fly on the wall video footage, riffs and excepts of the music, studio photos, cool contests, and some trips back in time to Lars' vault with live downloads and rare photos. You're going to be part of the experience over the next four months or so as we put the finishing touches on the album, including mixing, mastering, artwork, photo sessions, etc.
(Honestly, it's quite irritating to keep mentioning the new album with no name, aye?)

Sun Tech Days is happening in Manila!
On June 17-19, something they claim to be bigger than Java In Manila is coming to the Philippines. Register now and get an early bird discount!
(I'm not so sure if I could attend this one, though. It's a three-day affair, which means I have to file for a 3-day Vacation Leave. Oh noes~!)

Believe me, this day has positively raised my hopes on monetizing the blog and publicly offering internet services. To put my thoughts back on reviewing, I'm writing a very important thing I learned from my "last reading". I had my training 2 years ago but I never concentrated on logical operators, short circuit logical operators, in particular.
There are actually 4 logical operators in Java 2:
- && - short circuit AND
- || - short circuit OR
- & - (bitwise) AND
- | - (bitwise inclusive) OR
When used in expressions such as
if ((x<3) && (y>9))
the difference between the two set (short circuit and bitwise) of operators lie in their evaluation.
Using &&, given for example that x=5, only the first expression is computed. I was wondering how I got wrong in that one loopy problem involving this. Since it takes two true arguments for the AND operator to evaluate a true result, the second one in the example isn't worth evaluating anymore.
If the first expression in a (short circuit) AND results to false, the other is left unevaluated. On the other hand, a (short circuit) OR operator halts the evaluation of the second expression if the first one evaluates to true. Remember that it only takes at least one true argument in order for the OR operator to return true.
In other words, short circuit logical operators save time. This doesn't happen when using bitwise & and | operators, which surprisingly (for me) can also be used to evaluate logical arguments.

Just some rants on my exam schedule. I didn't expect the Taiwan earthquake to have such a toll on me. I called the testing center and I *might* not be able take the exam before February ends because of the telecom cables that have yet to be repaired. Need to pray hard this time.

I just found the link from the Javalobby.org newsletter. It's IceFaces, an AJAX-solution that uses no JavaScript at all... I just saw the demo here and I'm enthusiastic about trying it.

I spent my bonus yesterday on a Memory Stick Pro, which I've been planning to install on my Sony digicam. My other option was buying an external hard drive. However my laptop doesn't have USB 2.0 so I need to install an extra pc card for it, which costs around PhP2,000. I estimated the total cost to be around PhP7,500.
I was a bit hesitant on spending the money. Like you know, I planned on buying a Pen Tablet last year and I got it, but now I'm not even using it. I'm afraid same fate goes to the other devices I'm planning to buy. Besides, I don't feel like I can't live without it. Therefore, I must just indeed buy those that are really very important. So I backed out on buying the mobile hardisk and opt for my other plan instead.

Yaho watashi wa kataze! Panalo ang bagong Yahoo!
Apparently, new technologies carves the competition in every business, like these competing portal/search engine and other internet services. I first saw Google Mail (Gmail) using AJAX, then noticed Yahoo! Mail is slowly getting to that stage. Again now, it's not only Y!Mail but the mail portal itself is getting AJAXed. Ahh... now I wonder how and when will I ever implement that to my site.

Two weeks ago, we attended a seminar/training on AJAX and Jetty (a Java servlet container & HTTP server). According to the speaker, the rise of AJAX became the defense of some Java detractors as the reason not to program in Java. He refuted this hodgepodge however. Being one of the founders and primary developers of the Jetty, he revealed the new version's support on AJAX applications. Great. But knowing Java and it's bloody nitty-gritties, how will it fare in attracting new developers?

Yesterday, 25 Apr 2006 at Shangri-la Hotel in Makati was Java In Manila 3. Several experts gave talks regarding innovative technologies related to Java programming and development. Indeed, they were very technical & knowledgable persons, but I wish the accent hadn't come in the way. My current job allowed me to understand at most 2 of the talks given. I found Sang Shin's talk on AJAX and Web 2.0 the most essential among the talks given. And I think he's also the most understandable speaker among the others.

At last, they bought my Java certification voucher.
