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 [...]
It’s Not An IPad…

No, it won’t turn your netbook into an iPad, but it looks like a good way to check out the Android version that Samsung does not seem to want to give to my Galaxy S Plus anytime soon: Run Android 4.0 Ice Cream Sandwich on Your PC.
Ars Technica explains how the tiny Raspberry Pi will become a tool for human rights activists and privacy champions: “Raspberry Pi, activist tool“. The small Linux computer will encrypt chat messages using the Cryptocat software, and I suppose it won’t be too hard to do the same with email. For even more simplicity and user-friendlyness [...]
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 [...]
Some Thirty Years Ago
Posted in Linux, Society, Software, Technology on 12/01/2012 | 3 Comments »
Some thirty years ago, somewhere in 1982, I bought my first computer: a Sinclair ZX81. It’s hard to explain to my children, but the thrill I felt when starting up this little black box was fantastic – that probably explains why I’m still playing and experimenting with computer soft- and hardware today. I don’t know [...]
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
Posted in Java, Linux, Ubuntu, Web Development on 31/10/2011 |
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 [...]
RIP Dennis Ritchie
Posted in Linux, Software Development, Technology on 13/10/2011 |
The news is fresh from today, apparently: Dennis MacAlistair Ritchie died October 8, 2011, at the age of 70. Ritchie is best known as the inventor of the C programming language and as one of the creators of the Multics and Unix operating systems. His name isn’t as well-known as that of Steve Jobs, but [...]
Discovering Ubuntu (7)
Posted in Personal, Photography, Ubuntu on 08/05/2011 |
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 [...]
Twenty Years Of Linux
Posted in Linux, Software, Software Development on 12/04/2011 |
The Linux Foundation should have published this on August 26th, since that was the day in 1991 that Linus Torvalds told the world of his intention to create an operating system. But I’m not going to spoil their party: twenty years of Linux is worth a celebration. Check out the movie that tells the story [...]
