Google Chrome on Linux

Disappointed in not having Google Chrome for your favourite Linux distro ? Now you shouldn’t be. Fetch the Google Chrome packages from here. They are on the development stage and wouldn’t be a stable one. But you can give it a try. Features like Flash will not work in this release. Installing Google Chrome will add the google repository so your system will automatically keep Chrome up to date. (If you don’t want Google’s repository, do “sudo touch /etc/defaults/google-chrome” before installing the package.)

Have Fun.

Note: The Linux build still lacks certain privacy features, and is not appropriate for general consumer use.

Making Photo Slideshow DVD’s under Linux

As there are no simpler graphical tools available under Linux for this purpose, I’m explaining the method to create a slideshow video DVD of images/photos using a commandline tool called dvd-slideshow. Don’t be scared. It’s not that hard 🙂

It can be installed via Synaptic under Ubuntu OR you can fetch the latest from here.

Preparing your slideshow

Before generating a slideshow, you need to produce an input file which specifies which pictures to use, how long each picture stays on the screen and which transition effect is applied.

The simplest way to do it is to put all of your pictures in one directory and run dir2slideshow. This will create the input file for the next step. Although there are many configuration options, this command should give you acceptable defaults:

dir2slideshow -n 'test slideshow' -t 5 -c 1 slideshow_pictures

This asks to take all the (JPEG or PNG) pictures from slideshow_pictures, show them for 5 seconds and then crossfade to the next picture for 1 second. It generates a test_slideshow.txt input file. Pretty standard defaults, but the link above gives you a description of all the options available.

An interesting switch is -p if you want to generate a PAL slideshow instead of default NTSC.

You have then a file describing your slideshow’s characteristics. Its syntax is fairly straightforward; you can hand-edit it if needed.

Generating the slideshow

Once you are happy with your input file, generating the slideshow is something as simple as typing:

dvd-slideshow -n 'test slideshow' -f test_slideshow.txt

If you add the switch:

-a audiotrack.ogg

it will add an audio track to the slideshow. The result will be 2 files: test_slideshow.xml and test_slideshow.vob. You can try playing your slideshow with mplayer:

mplayer test_slideshow.vob

If you are happy with it, you can move to defining the menu. The thing which this tool amazes me is that it took only 22 minutes to render 580 photos to a DVD video with 10 mp3 sound tracks. In Windows media player, making a video of 100 images with audio backgrounds will surely take more than half an hour 🙂

Making DVD menus

You can use the tool “DVD Styler” for this purpose. (Availabe in Synaptic)

Encrypt Emails within Firefox

FireGPG is a Firefox extension under MPL which brings an interface to encrypt, decrypt, sign or verify the signature of text in any web page using GnuPG. FireGPG adds some features to the Gmail1 interface, to let you use GPG’s features directly in your webmail. More webmails will probably be supported in the future. FireGPG is able to detect PGP blocks in any page (for example a public key), and lets you easily manage these different blocks.

FireGPG isn’t a key manager. You must install the GnuPG software!

On GNU/Linux and Mac OS, it’s GnuPG. You can install it with your favourite package manager (like Synaptic, YaST, Yum, etc.) or from its official website.

If you are using Microsoft Windows, you have to download WinPT and GPG, and install it at the default location.

Install FireGPG

Control your computer with your Bluetooth Phone

What is anyRemote?

anyRemote logo The overall goal of this project is to provide remote control service on Linux through Bluetooth, InfraRed, Wi-Fi or just TCP/IP connection.

anyRemote supports wide range of modern cell phones like Nokia, SonyEricsson, Motorola and others.

It was developed as thin communication layer between Bluetooth (or IR, Wi-Fi) capabled phone and Linux, and in principle could be configured to manage almost any software.

anyRemote is console application, but in addition there are GUI front ends for Gnome and KDE.

[DOWNLOAD ANYREMOTE] (anyRemote application)

[DOWNLOAD GANYREMOTE] (GUI frontend)

[DOWNLOAD JAVA CLIENT FOR PHONE]

The configuration files can be found in /usr/share/anyremote/cfg-data. Now you may be able to control applications like Totem/MPlayer/XMMS/Impress/Evince etc. with your phone running the Java client.

NOTE: A bluetooth USB dongle should be attached to the computer to use anyRemote.

Video Encoding made easy

There are several video/audio encoders available in Linux like Ffmpeg and Mencoder. But not everyone like the commandline version very much. But there are also GUI  front-ends for both these encoders. Avidemux and Vive are the GUI front-ends for Ffmpeg. And GMencoder is the GUI frontend for Mencoder. I built a deb package for these to install them on Ubuntu.

In order to use these tool you must install the Ffmpeg/Mencoder through Synaptic.

[Download Vive]

[Download GMencoder]

Also if you don’t want the GUI’s and stick with the commandline version. This page helps you to create custom commandline arguements for Mencoder.
