Just a quick notice, to speed up my future use of this command: if you want to set another default Java version in Ubuntu, use the update-java-alternatives command. For more details, see Ask Ubuntu, knowing that this command (probably) works in multiple version of Ubuntu – I’m on 12.04 and it worked fine for me.

How To Set The Default Java Version In Ubuntu

To install a working Citrix Receiver on my 32-bit Ubuntu 11.10 machine, I had to execute these steps: Download the .deb package from Citrix. Install the downloaded .deb with Ubuntu Software Center. In a terminal window, execute “sudo apt-get install libmotif4“. That made it possible to run the application. So I tried to reach the company [...]
Is It A Phone, Or Is It A Computer?

If you’re still doubting that “smartphones” are real computers, just check out this article: “Ubuntu for Android: Canonical brings Ubuntu desktop to docked smartphones“. OK, you currently need a top-end smartphone with a dual-core ARM CPU and HDMI output, but in this market today’s top-end machine is tomorrows standard. To further prove the point: TextWarrior [...]
Your Web Application In The Cloud

Planet Python pointed me to “Setting up Django 1.3 + NGinx 1.0.5 + Green Unicorn 0.13 in an Ubuntu 11.10 EC2 instance“. This is a detailed tutorial on how to get a nice web application runtime installed on an Amazon EC2 instance. The comments make it clear that the described procedure actually works ;-) This [...]
Take Care When Naming Tools

Last week, I had to get a few web applications running on my Ubuntu netbook. That shouldn’t have been too difficult: after all, I have installed Tomcat on many servers (mostly Windows-servers, admittedly, but on OSX too), and getting a web app like JSPWiki to run on Tomcat is something I have done many times. [...]
Strange – or not: after a reboot, updates for Ubuntu e.a. installed flawlessly. You can forget my questions from a few days ago ;-)
An incomplete installation is, unexpectedly, incomplete. I wrote about the non-installation of a series of certificates during the upgrade to Oneiric, and yesterday I discovered the consequences: Oneiric is incapable of doing updates. Yup, not even security updates. As an Ubuntu newbie, I haven’t got a clue about how to redress the situation and add [...]
Yesterday, my netbook proposed to install the Oneiric Ocelot aka. Ubuntu 11.10. Just a few clicks later the machine went to work for a long time (hey, it’s just a netbook, OK?) – and stopped two times with error messages. First of all, it managed not to install a long series of certificates. Near the [...]
Discovering Ubuntu (7)

Two weeks ago, Nikon published an update for the D7000 DSLR camera. The update process requires copying a .BIN file onto an SD card, so I thought: let me try that on the EePC netbook, which has a built-in SD Card slot. Unfortunately, Nikon has downloads for Windows (an .EXE file) and Mac OS X [...]
A few hours ago, when I activated my EeePC netbook, the Upgrade Manager asked me whether I wanted to upgrade to Natty Narwhal, that being the latest Ubuntu release 11.04. Since I don’t have essential data on the hard disk, I said to myself: why not? Clicking OK started a long process that didn’t need [...]

This is not specific to Ubuntu, but anyway: I wouldn’t have realized it if I hadn’t installed Ubuntu. What’s “it”? Well, Since I wanted to use my EeePC for light development, I had hoped to be able to run the OPML Editor on it. But although there has long been talk of getting Frontier up [...]
The netbook screen on my EeePc seems a bit too small to use the Eclipse IDE with all its panes. I’m not a fan of the *nix classics Emacs and Vi – I’m probably too spoiled by GUI’s. I managed to get Editra up and running, although the installation wasn’t all too evident. Actually, the [...]

I admit it: this post is more about the richness of the open source software “offering” than about Ubuntu, but it’s through the installation of Ubuntu that I (re-)discovered a series of high-quality tools for my hobby – (digital) photography. In summary: I have already installed the following tools on the EeePC: DigiKam – http://www.digikam.org [...]
Discovering Ubuntu (2)
Posted in Mobile Computing, Ubuntu on 02/03/2011 |
Quick note to myself: if I want Ubuntu to go online through my mobile phone, then I have to tell my Nokia to start the “PC Suite” (and not “Connect PC to Web“) when I connect it to the netbook! Once that is done, everything goes smoothly – I had the configuration of the connection [...]
Discovering Ubuntu

I’m trying to get to grips with the Asus netbook I bought, and with the Ubuntu 10.10 Netbook distro I have installed on it to replace Windows7. So far, so good: I’m beginning to understand the Unity desktop that comes as a default in this Linux distribution, and I must admit that it doesn’t feel [...]
