There is an online article that states that Java developers just do tools for each other but not good apps for users. The article exaggerated to be doutrageous, but it contains lots of truths.
If you Java-ified Ruby, we will have more developer-tools and more e.g ant, maven, other many just for 'making'.
And fewer and fewer apps/
How many Java forums to challenge PhpBB, Moodle etc? Wikis?

Hi,
I read that article about 3 years ago, and right now I cannot find it on Google.
I want to apologize if I've sounded like a troll here.
(1) I have nothing against the author/Enebo or the project.
(2) I am not even against JRuby. I am even agitating the use of JRuby in my local Ruby user Groups. I am all for calling Java/C++/Lisp from Ruby.
What I can't stand is what I would call Java-ism. esp. DOWN WITH THE SUN!
(1) When Bruce Tate talked about bloat in his "Faster, Lighter, Better Java," I don't agree.
(2) When DHH and team separated out a lot of stuff from Rails core, I don't agree.
I like bloat. We need bloat. e.g. Why don't DHH team take out ActionMailer from core? Go ahead email is not core to MVC, right?
Every popular/useful language/framework grows. We welcome it. But how it grows can often rub us the wrong way. eg. Java Swing, JMX API, EJB, JDO, so many API's made in SUN! May SUN rest in Peace!
Suppose, if I design Rails 34.56, I would like it to include modules for
(1) rendering views in iPhone platform
(2) rendering views in Symbian platform
(3) rendering views in Android platform
(4) rendering views in some other unknown mobile platform
...
(56) integrating with popular CMS like Plone, Zope, Joomla etc
...
(78) Calling Erlang
(79) calling Thrift
...
What is wrong with that?
We are not mono-cell amoebas. How did we grow our eyes, ears, legs, limbs?
The more complex, the better! The more bloat, the higher up in the food chain!
Go argue with Evolution, with Biology.
But, Evolution didn't work like SUN architects. When you get your left toe hurt, you suddenly don't get a headache or an eye blur or a stomach ache. What I am talking here is MODULARITY from the user's perspective. IS THAT TOO deep to understand for SUN/Java API designers?
SUN is declining, or we may have to learn EJB 12.56 etc. How many Java API's have gone down the drain?
Joel Spoloky says we programmers don't read, not even our own industry's history.
No time for Biology and Evolution?
Fine, please read Robert Glass, at least.
IF I SOUND arrogant/angry, please bear with me. I AM JUST TYPING IN A rush.
I love you all ;-)
