Of Java and Assembler

Posted in Blogroll, Random Thoughts, Tech at 6:04 pm by Liv

The title would no doubt puzzle quite a few of you — after all I’m putting in the same sentence a low-level, processor-specific language (for no better term for “assembler” — I know, I know, I know, “it’s not really a language”, right?) with a rather high-level, even platform-independent language like Java. So, right away you’d all be asking yourself “well, what can they have in common?” — or probably thinking that this is an article looking at how far apart these 2 languages are. The thing is, they’re not actually that far apart! Yup, I’m going to say that again and re-phrase is so the purpose of this post becomes more clear: they are quite similar in fact!

Now, I bet this got your attention, didn’t it ? Rest assured, I didn’t just say it for the sake of it — I will try to explain throughout this post how that is possible. And if you decide to read it all, and happen to work within the JVM space, I would be very interested to hear your thoughts on this — either via a comment here or simply drop me a line.

(Small) Bug with Oracle’s HTML/JMX Interface

Posted in Blogroll, News, Tech at 3:39 am by Liv

I posted before an article about how to use Oracle’s (well, Sun’s, since it was started really before the Oracle acquisition) HTML/JMX agent to monitor your apps via JMX here. For those of you who went ahead and decided to use that interface, you probably noticed a small (but rather annoying bug) in that component — or maybe you haven’t, in which case, you will know how to avoid it if you read this.

It’s not a big deal to be honest, as you are about to see — especially if you are dealing with clean code or code you’ve written yourself and understand the functionality ahead. But if you are trying to use the “help” facilities of Oracle’s JMX/HTML console you might find this rather annoying.

As a side note, I’d be more than glad to submit a patch for this somewhere, but bloody Oracle has discontinued this component So if you find out where I can submit the patch, drop me a line and let me know — much appreciated in advance!

Batch Source Formatting in Eclipse Indigo

Posted in Blogroll, News, Tech at 5:41 am by Liv

This has been bugging me lately — how to do a batch formatting using Eclipse!

If you plug things like Checkstyle (and PMD to a certain extent) in your project build, you get bugged every now and then when someone else makes a change with stuff about tabs/spaces, brackets being on the same line or not, line being too long etc etc etc. Typically what you do in this instances, you just open the file in Eclipse, and a simple Mac+Shift+F (or Alt+Shift+F on Windows) automatically formats the source and you’re good to go!

However, what do you do, when you see a Checkstyle report reporting 100′s of issues across say 10-20 different files? You could of course set off to process every file manually — if you have the time! — or look for a way to do this using Eclipse in a batch manner. I personally opted for the latter — and this is how to do this using Eclipse.

Customizing Squirrel Mail Login Page

Posted in Blogroll, Tech at 1:44 pm by Liv

For those of you who are using SquirrelMail, you might have noticed that it looks a bit well, let’s just say amateurish That doesn’t go to say it isn’t a good package! (I personally love it and I think it does a pretty good job — hence my additions to this software.) However, as every open-source package in its early stages, there is still a lot more to be done to get it to a stage where it works beautifully and looks just as good! If you have been using it for a while chances are you have already installed some of the plugins and configured them to your needs. Some of these plugins as you know allows certain visual customizations to SquirrelMail to make it look more pleasant to the eye.

It is one of these plugins that captured my attention, as I figured out straight away it will allow me to customize the login page! And here’s how:

Java vs JavaScript?

Posted in Blogroll, Random Thoughts, Tech at 10:31 pm by Liv

The title of this post was intentionally chosen to raise some eyebrows – after all we all know that in most cases (I’m taking the likes of Rhino out of the equation, same for applets) the former resides on the server side while the latter is used as a client-side language. So why would someone have a go at comparing them?
I guess the post really is more about questioning whether we should move most of the processing on the server side or whether it is a good idea to leave some of this to the client side.
Let’s start with some basic example: showing the user the local time and date. (By local I mean local to the user!)
