A goodbye to Java

In the past I already removed Flash and Mono from my systems due to security concerns, but since CVE-2011-3544 it was the final call for Java. It took some dependency checking as Debian was replacing OpenJDK with GCJ or vice versa in most cases, but the command below finished that on a lot of systems. I said farewell to NetBeans a long time ago since it was to slow on my system and the only thing left was LibreOffice Base that needed to be removed as well.

$ sudo apt-get remove --purge libgcj12 libgcj-common gcj-4.6-jre-headless \
    libgcj12-awt default-jre-headless

This action also made me wonder about the state of LibreOffice as it is mainly a big blob of code on the system like Firefox is as well btw. I read on there website somewhere that making Java an option is a long term goal, but will it be enough? For now it should be, as I prefer my documents in OpenDocument-format. When the next GTK3 based version of Abiword and Gnumeric are released I need to do some testing again to see if they support OpenDocument now better.

Adopting NetBeans

Duke with helmetI’m from the Borland “blue” IDE generation and it was my favorite IDE for both Pascal as C/C++. But somewhere around Borland C/C++ 4.5 they changed to a Windows-interface and I was horrified at the time. I never found a good replacement and I tried a lot. KDeveloper looked promising, but limited to KDE-only at the time I stopped using it.

A lot people advised me to try Eclipse and so I did. I only ended up in wanting to shoot the bureaucrat who designed it. At the time NetBeans was also still a pain to use, but now with generation 6 is becomes a good alternative to use. It supports Java and C/C++, but also PHP, Python and Ruby. And tons of useful things like screening your code for FIXME-statements, but also ways to use remote webservers and repositories.

I’m now already on version 6.5.1 and using it more and more for PHP-development. Hopefully version 6.7 will become faster and less memory hungery as 500 MB allocated memory for an IDE is somewhat on the big side. This may be related to Java on 64 bits Linux, but I still need to test it on OpenSolaris for comparison. But for now it seems I found my new IDE as I’m slowly adopting it for more and more tasks.

JavaOne 2009

Duke with helmetJava has had a bad start and has a bad image, but it appears to change as also shows during JavaOne 2009. The changes with Java 5 and Java 6 are starting to show for the better. But the most important highlights for now are JavaFX, project Jigsaw and the Java Store. If I needed to choose between .NET or Java for a new project, then I would put my money on Java.

The most important news may be that Classpath is going to disappear and that you can strip down Java to only ship what you need. Here comes project Jigsaw into the picture to get Java on every computer, phone and appliciance and in a shape it should be in for that situation. With a live presentation of a working television that was able to run JavaFX it may become clear where the newly announces Java Store fits in.

It all starts to fit together with upcoming NetBeans 6.7 when you take project Kenai and Zembly into account. There are developer tools, a place to host your development and application, a place to sell it and also a device to run it on. Is Java going to change television as it did with mobile phones?

Java Web Start

Er kunnen veel dingen worden geschreven over Java, maar sommige features zijn best mooi ontworpen waardoor je je afvraagt hoe men z’n visie kon hebben zoveel jaar geleden. En ook een sterk geloof om er aan te blijven werken. Een van die features is Java Web Start waarbij een Java Runtime Environment en een kleine XML-file voldoende is om gebruikers toegang te geven tot een applicatie welke niet is geinstalleerd op computer zelf.

Ik begin me steeds meer af te vragen tot hoever ze Java al hebben uitbedacht en hoeveel nu is geimplementeerd. Zeker als je kijkt naar Solaris waarbij men nu pas begint toe te komen om onderdelen van het design te implementeren welke al 25 jaar geleden zijn uitgedacht. Het is dan ook zonde om z’n bedrijf langzaam kapot te zien gaan en hopelijk reden ze het, want er gaat nu al te veel goede kennis verloren.
