Revealing Steganographic Content in Images

Quite a while ago I showed how to hide your files with steghide, a tool used to embed information into a jpeg image file. Today I will show you how to detect a file already “stegged” without prior knowledge and possible extract the information from the image file. For this demo, we will use a tool called Stegdetect, available here (notinh this link is for you ;).

Amazon MP3 Now Open To Linux Users

Amazon MP3 has been around for several months now. And it’s doing pretty good. Decent amount of press coverage when it hit the stage. Decent song selection, all with decent sound quality. And just about everything is decent with the all-DRM-free program Bezos & Co are touting out in the cloud.

PHP programming on Ubuntu 7.10

We can do PHP programming by any text editor, such as vi and nano. However, a Integrated Development Environment (IDE) is good for debugging. For IDE, I choose EasyEclipse for LAMP and it is not required to install. Download it and double click it to run. However, we should install some server programs and do some configuration before using it.

Subtitles, Video Editing and DVD Authoring in Ubuntu

Translating movie subtitles is my new hobby. I had no previous knowledge of what subtitles are, how they are embedded in a DVD movie, how to rip them off, how to create new subtitles, and then finally how to prepare a DVD with translated subtitles that could be played on most popular software, hardware and standalone DVD players. I found out that it was not an easy job to embed UTF-8 encoded text on DVD as a separate subtitle stream. So I decided to hardsub my movie, which means that users will not have the option to turn off the Urdu subtitles.

mplayer - command line movie and music player - music over ssh

Mplayer is one of most known movie players in Linux, and also in Mac OS, and Windows. To install it in Debian / Ubuntu run:

            sudo aptitude install mplayer

Mplayer has lots of options, and we will explore some of them here, the files format it can play according to its official site are:

Open source makes a healthy site for healthy eaters

TheDailyPlate.com (TDP) is a free, online eating journal with a lot of features that make it useful for the health conscious. The site is developed completely in PHP on MySQL, Apache, and Linux. LAMP was a natural choice, the founders say, because so many other Internet companies have experienced success with the now-ubiquitous platform.

Openbox, xcompmgr, transset & Conky

I had some spare time yesterday and I decided to spend it playing with compositing under Openbox. I'm not normally too fussed about having eye-candy on the desktop; however, a few people have mentioned 3D effects, in IRC and on the forums, so I thought I'd have a go at configuring xcompmgr on one of my systems.

Eight Interesting Improvements In GNOME 2.22

Back in November we started sharing some of the exciting features planned for the GNOME 2.22 and 2.24 releases, and now that the first GNOME 2.22.0 Beta release is planned for later this week, we have taken another look at the packages set for inclusion and the changes that have actually been made. While nothing groundbreaking will be introduced in GNOME 2.22 (compared to KDE 4.0 at least), this desktop environment does have some moderate changes worth noting.

Nexuiz 2.4 Offers Impressive Graphics

Since the release of Nexuiz 1.0 in 2005, we have been tracking its progress as one of the leading open-source first person shooters. With time, this fast-pace game has picked up a nice level of artificial intelligence for its in-game bots, engine optimizations, single-player campaign missions, and a variety of technical advancements. Nexuiz has always been one of the leading open-source first person shooter games, and with the release of Nexuiz 2.4 yesterday it reaffirms that you don't need to be a major game studio -- or a game studio at all -- to develop a quality title and even for being a free software game it has impressive graphics.

New add-ons for OpenOffice.org Writer

After a slow start, add-ons for OpenOffice.org are finally starting to reach a critical mass. When I last wrote about add-ons for OpenOffice.org in September 2004, the examples were relatively limited, with extendedPDF the outstanding example. Today, extendedPDF remains a must-have -- so much so that Debian versions of OpenOffice.org include it as part of the basic packages -- but the choices have expanded dramatically. There is even a web page that is slowly beginning to rival the Firefox extension page.

Cool Desktop Linux Applications(Part 1) : Internet and networking applications

Desktop Linux has seen tremendous growth over the past few years and with this there has also been tremendous growth in number of applications relevant for desktop use available . Now most of the Linux distributions because of either space constraint or well because of licensing issue do not include many really cool applications .

Xrandr GUI

Finally today we've uploaded the new Xrandr GUI to Ubuntu Hardy. I mentioned working on a tool a couple weeks ago; I discovered that Soren Sandmann was also working on such a tool and was further along, so I shifted focus to getting that tool ready for integration in Ubuntu.

Ubuntu 8.04 Hardy Heron Alpha 5

It's getting to the point where I should just rename "April" and "October" on my calandar "Ubuntu!" because that's what it just boils down to. If you have any interest in the state of open source software then you'll know that Ubuntu tends to be the benchmark; the high standard that other releases are measured against (whether it's suitable or not).

Extending Ubuntu's Battery Life

Last week when traveling to Europe for FOSDEM and other business meetings, I had picked up a new 9-cell battery for a Lenovo ThinkPad T60. While an additional three battery cells will noticeably extend your battery life, you can also extend your battery life by taking a few simple steps to optimize your Linux desktop that will also reduce your power consumption and heat output. In this article are a few simple steps to take in order to extend your notebook's battery life on Ubuntu.

Nexuiz 2.4 has been released

Lee Vermeulen's brainchild Nexuiz is a fast-paced first-person shooter, better comparable to Unreal Tournament than to Quake, though based on latter's engine. Release 2.4 has been available for some hours now. Time to grab a copy and freaking play it. But first, let me bore you some. (Not recommended, skip following paragraphs, you could be fragging already! Time is money! Go shoot stuff!)

Change Wallpaper Easily With Wallpapoz

Wallpapoz is an easy to use wallpaper changer application for GNOME. If you love to collect wallpapers, and like your desktop to change wallpaper at regular interval, then Wallpapoz is right for you.

My top 10 Firefox extensions

1. It can only be Tab Mix Plus. This extension does almost anything… from undoing closed tabs, open all links in new tabs only, multiple row tab-bar, reload every N seconds a tab to session manager. Love it.
2. Foxtrick. In my good old hattrick-addict days, i couldn’t play hattrick without it.
3. All-in-one Gestures. Easy navigation using mouse gestures. Like holding down right click and moving the mouse to the left makes a webpage go back, down makes a new tab open, etc etc… simply brilliant!

Very simple video editing/DVD burning in Ubuntu

You have a IEEE1394 (Firewire) camera and you want to burn your birthday/wedding/funerals on a DVD. And maybe cut the scene where you look silly, dancing madly with a potato in your pants. It's Ok, Ubuntu can save your reputation...

Audio conversion tools for Linux

Most portable audio players can play music encoded in the MP3 audio format, but some consumers also have music in Ogg Vorbis, FLAC, MPC, or even WMA files. How do you change from one format to another when you need to? Here are some of the best audio conversion tools available in Linux.

What Would You Like to See in Ubuntu?

Ubuntu looks as though they have taken a page from Dell’s book. The Ubuntu team just launched a new feedback site called Brainstorm which closely resembles the Dell IdeaStorm site that was launched over a year ago. It provides a Digg-like voting interface to figure out what the community would really like to see come out of Ubuntu in the future.

GNOME focuses on accessibility -- with a little help from Mozilla and others

The GNOME Foundation has turned its attention to accessibility for people with disabilities. To help improve both Web accessibility within GNOME and the project's long-term direction, the Mozilla Foundation is joining the GNOME advisory board, and plans to help improve integration of the XUL development platform with GNOME. Even more significantly, the GNOME Foundation, the Mozilla Foundation, Novell, Google, and Canonical are jointly sponsoring a $50,000 outreach program to help improve accessibility in GNOME.
