Still no javafx for Linux? March 3, 2009

javafxI use a lot of Sun software: java, mysql, virtualbox, solaris, solaris cluster, etc.

Today, while having a look at webservices as an alternative to Swing clients, I decided to have a look at Sun’s attempt at the RIA market: Java FX.

Sadly, the javafx sdk has only be released for windows and macos. I guess Sun doesn’t get it that it needs as many developers as possible as its alternative is a few years late compared to the competitors. And a lot of linux users are developers/admins…

I know they are workarounds to get the sdk running on linux, but why bother?

Fixing Linux webbanking on Belgian ING bank November 2, 2008

Most banks use a token generator device in combination with a -Operating System independent- website. However, for cheap Internet banking accounts, ING uses a software “Security module” to save some euros on hardware. Crap.

When I had a look at their homebanking website, I was surprised that there were debs available. Sadly, the debs are rather old and depend on old versions -not installed- of libraries. Nothing that can not be easily fixed.

A bibliography manager for *n*x: JabRef September 16, 2008

PhDI have been pretty busy lately (that’s why I haven’t posted a lot). I started writing a PhD dissertation. In order to sort the hundreds of books, articles and original sources I had a quick look at free and open source bibliography applications for *n*x. I was sure I would need to write my own (a light-weight db and a java swing interface) to get the fields I need and have strong search capabilities (SQL). Luckily, I was wrong.

EDIT Oct 13 2008: Fix for wireless problem (sometimes difficult to connect to Access Point)

EDIT Feb 10 2010: This HowTo is no longer needed on Ubuntu 9.10. Everything OK out of the box.

HP gave us hplip linux drivers for their printers, so when I needed to buy new computer stuff I bought HP (laptop and color laser network printer). Everything (screen resolution, graphics hardware acceleration, wifi, etc) works out of the box. No surprise really, as all these components are Intel with known open source drivers.

Anyway, there is one little thing you need to do make of this laptop a dream GNU/Linux laptop. (more…)

VirtualBox: Install Windows XP using pbx boot June 24, 2008

VirtualBox is a great product for a developer (or even a regular user) to run several OSes simultaneously. I run Linux on my laptop, but I need a Windows partition with certain software and updates to connect to the work network. A virtual machine is a fine solution. Specially when running in seamless mode (only the program is open in your Linux desktop and not the complete Windows desktop).

Installing Windows from cd on a VirtualBox instance is really easy. However, I need a *specific* windows installation that can only be installed from a Windows PXE server at work. Sadly, the virtualbox open source edition delivered with Ubuntu 8.10 is unable to do this. This is what I did: (more…)

OpenJDK Swing in Gtk clothing: getting there? June 2, 2008

Sun has a golden opportunity to make the dream of Desktop java reality. Although java is predominant for enterprise applications and on the server room, java on the Deskop – whatever Sun claims – is not a reality.

Things have changed since the days of over-hyped applets. Java SE 6 is nice and getting better and swing – and java in general – have made huge speed improvement (hotspot and co.). More important, java is now free.

CPAN on Ubuntu fails on bug IO/Uncompress/RawInflate.pm: solution May 30, 2008

apt-gettable perl modules on Ubuntu are great. A nice packager at Debian Gnu/Linux compiled the modules and included all dependencies specially for you :) .

This is extremely handy when you are looking for a solution for a programming problem that you know someone else solved before. You apt-get the modules you need and have a quick try.

While doing exactly this (tryng to install HTML::TextToHTML) , I discover CPAN on Ubuntu was broken:” Can’t call method “value” on an undefined value at /usr/share/perl5/IO/Uncompress/RawInflate.pm line 64.”.

I don’t think it’s a Debian/Ubuntu problem, but rather a upstream bug. Some people have the same problem on Windows. How nice the apt-gettable modules are, there are always cases when you need to build modules not yet in the Ubuntu repositories or you need a newer version (both cases here). A non-working CPAN is not acceptable. This is what I did. (more…)

A wifi-connected laptop as a home server May 29, 2008

As probably many people nowadays, I only have laptops at home. Actually one for me and one for my girlfriend (luckily babies don’t need laptops yet :) ). As we made the move to laptops a long time ago, you end with older – perfectly fine – laptops. Similarly, I stopped making holes in the walls a long time ago and went wireless.

Laptop and wifi do not sound like a winning server combination, but for me they are. Happily, nowadays wifi is as easy in Linux as in Windows or MacOsX. But do you really want you laptop to use a graphical semi-interactive process to get it’s – often random – IP address? What if the machine will run without an X server?

wpasupplicant and the old manual network configuration come to the rescue. I use this configuration for my graphical over-sized living room divx/mpeg/flac/ogg/mp3-player laptop connected to my tv and stereo and non graphical print server (an old trusty amd 350mhz cpu with 160 mb ram and 4 gb disk) in the home office (far from the living room where we often work).

For the googlers out there: Ubuntu 8.04 – and for that matter the previous versions as well – works completely out of the box on this laptop.

Ubuntu on HP nc6230 laptop May 28, 2008

This is just a wrapper post for all the people googling for installing GNU/Linux on a nc6320 laptop:

Ubuntu 8.04 runs just fine on this laptop (bluetooth, card reader, 3D compiz effects, etc, etc). The install is very easy and straight forward. There are two things you need to fix: enabling the mic and pump up the wifi speed. The only thing I haven’t tried is the fingerprint reader (I find it silly).
