Making GWT 1.5.x Hosted mode work in Ubuntu Karmic

admin — Mon, 12 Oct 2009 09:12:11 +0000

Since my last post on making hosted mode work on Ubuntu, I had upgraded my laptop to Kubuntu Karmic ( in Beta 1 as of this writing ). While most things worked out of the box ( including wireless, mic / webcam, ZTE AC2726 modem ), I got a problem with a GWT 1.5.3 application again.

GWT 1.5.3 hosted mode requires libstdc++5. Kubuntu Karmic doesn’t ship libstdc++ 5 anymore.

Fortunately, the solution was simple.
Download libstdc++5 package for your architecture from Ubuntu Package Archives.
I used i386 version

Install the package

sudo dpkg -i libstdc++5_*.deb

You should now be able to run GWT 1.5.x hosted mode browser running again. ( This might work for GWT 1.6.x as well considering that both use Mozilla 1.7.1x that depends on libstdc++5)

ELCOT Student Laptop Offer

ELectronics COrporation of Tamilnadu (ELCOT ) is running a Student Laptop offer. As per ELCOT’s website the offer is providing the laptops at a discounted price for students.

The laptops come preloaded with SUSE Linux. Apart from the default software applications that come with most standard linux distrubutions today, they also have

NetBeans IDE
Nero Linux ( though KDE native K3b is also bundled )
Postgres database
JasperReports ( an excellent report rendering software based on Java )

Based on the list of bundled softwares I guess it might have KDE graphical desktop environment.

On the hardware side, they ship two brands. Though the brand name is not mentioned, From the specifications and sample picture, one model seems to be HP dvNNNN series. These laptops are quite featureful. I use dv6000 series and most features work out of the box with Kubuntu 7.04.

It is to be noted that ELCOT is pro-open source, and is pushing Linux across the government offices in Tamilnadu. If I remember right, It is also the “purchase” department of IT hardware / software for most government functions in Tamilnadu.

Virtual Barbershop – Amazing Audio

Vijayakumar K — Sat, 02 Jun 2007 12:53:07 +0000

I came across an audio called Virtual Barbershop couple of days back in David’s blog. It is by far the best Audio Effect I heard. You might be thinking you need 5.1 ( or 7.1 ) channel audio system to get the best audio effect. Wrong!!! All you need is a pair of simple earphones.

Listen to this with your earphones, preferably open ear type. http://david-heron.me.uk/blog/2007/04/08/virtual-barbershop/

You could also play it from your favorite MP3 player, from http://www.david-heron.me.uk/blog/wp-content/VB1.mp3

If you’re interested in the technology behind this, refer to Binaural Recording. The excellent shareware software BrainWave Generator also uses binaural audio.

I would be happy to receive your feedback.

Fedora team announced release of Fedora 7 on 31-May-2007.

This release’s key highlights include

It’s not Fedora Core anymore. Starting this release, it will just be called Fedora.
KVM integration with Fedora’s graphical virtualization manager virt-manager.
Experimental nouveau driver for nVidia video cards. This might be good news for people who are required to compile the nVidia drivers with each kernel release. The driver is disabled by default.

Fedora team has already posted a Schedule for Fedora 8 , which is planned to be released in about 5 months.
