Actual meaning of Free Software: Free as in beer versus Free as in speech

Vastness of open source can leave anyone in confusion. Whether it is distro hunting or phrases that are used to explain related concepts. The one which annoys every single beginner is that Open source is said to distribute free software, so far so good, but what exactly we mean by free? Free as is Beer or Free as in Speech? Keep reading.

The difference can be narrowed down to “no money” versus “no restrictions (or a bit of them)”. In English, free is often mistaken for both the meanings but in Spanish they have different words for them, Gratis and Libre.

Free as in Beer (Gratis)

Java from Oracle is a product which is free as in beer. When you are offered a beer, you are not supposed to pay for it but enjoy. The ‘body’ giving away pays for it and everyone enjoys it at no cost.

Java from Oracle is available free of cost for everyone but restricts users from getting even a glimpse of source code. Hence, users are also deprived of the liberty of modifying the code. Speaking of that, none of distributing publicly and submitting bug fixes is available. The decision of What/When/How you get the “beer” is made by the “giver”.

Free as in Speech (libre)

In addition to facility of getting the software for free, the air of liberty comes in. The liberty in “libre” is more than you get in “gratis”. Following are the rights you have in software which are Free as in Speech:

♦ You can use it anyway you want. They don’t care if the software was made for computer you are running it on mobile device. More the merrier!

♦ You can easily see the internal working of the software. Users want to know the secret ingredients in their favourite beer but are deprived of this pleasure in case of free beer.

♦ Sharing is caring! After using and falling in love with the software, one would definitely want to share it and libre allows him to do that without violating any law. Distribute it publicly whether by packaging it with your software or provide a mirror, etc.

♦ You can be a part of the development process. If you find a bug and a fix to it, you can submit it so that community benefits from it. After all it is all about giving away.

First beta of gnome 3.4 released

gnome 3.4

Gnome is making another step forward. The news just came that first beta of Gnome 3.4 is out and is approaching the release time. This release is meant for testing and hacking purposes. Being a beta it can be built and used but should be avoided for hardcore purposes. Gnome uses its own nomenclature to signal development status. Interested folks can have a look at their brief schedule here. This release is first beta to the final release. We have second release scheduled on March 7th followed by candidate release on March 21st.

Final release of Gnome 3.4 will hit the web on March 28th.

A complete ffmpeg tutorial

Introduction

ffmpeg is a very fast video and audio converter that can also grab from a live audio/video source. It can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter.

Installing ffmpeg

chankey@linuxstall:$ sudo apt-get install ffmpeg

Uses

Below are some tasks which you can perform using ffmpeg.

Getting information of a video

To get information of a video file use -i option as:

chankey@linuxstall:$ ffmpeg -i /path/videofile.avi

Making video from images

You can combine the images to make a video (like movie maker in windows) using ffmpeg as:

chankey@linuxstall:$ ffmpeg -f image2 -i image%d.jpg videofile.mpg

The above command will take all the images from the current directory (image1.jpg, image2.jpg, etc) and will join them to make a video file videofile.mpg.

Making images from video file

This is just opposite of the last step. This will take a video and will generate images from it.

chankey@linuxstall:$ ffmpeg -i videofile.mpg image%d.jpg

Encoding video for iPod/iPhone

Source file: s_videofile.avi
Audio codec: aac
Audio bitrate: 128 kb/s
Video codec: mpeg4
Video bitrate: 1200 kb/s
Video size: 320×180
Generated video: f_videofile.mp4

chankey@linuxstall:$ ffpmeg -i s_videofile.avi input -acodec aac -ab 128kb -vcodec mpeg4 -b 1200 kb -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 320*180 -title X f_videofile.mp4

Encoding video for PSP

Source : s_videofile.avi
Audio codec : aac
Audio bitrate : 32 kb/s
Video codec : xvid
Video bitrate : 1200 kb/s
Video size : 320×180
Generated video : f_videofile.mp4

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -b 300 -s 320x240 -vcodec xvid -ab 32 -ar 24000 -acodec aac f_videofile.mp4

Video to Audio

You can extract the audio from a video file and save it as mp3 format.

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 soundfile.mp3

Source video : s_video.avi
Audio bitrate : 192kb/s
output format : mp3
Generated sound : soundfile.mp3

wav to mp3

chankey@linuxstall:$ ffmpeg -i s_audiofile.wav -acodec mp3 -ab 192k f_audiofile.mp3

avi to mpg

chankey@linuxstall:$ ffmpeg -i s_videofile.avi f_videofile.mpg

mpg to avi

chankey@linuxstall:$ ffmpeg -i s_videofile.mpg f_videofile.avi

avi to flv

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv f_videofile.flv

avi to dv

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -s pal -r pal -aspect 4:3 -ar 48000 -ac 2 f_videofile.dv

avi to gif

chankey@linuxstall:$ ffmpeg -i s_videofile.avi f_giffile.gif

Mixing video with a sound file

chankey@linuxstall:$ ffmpeg -i s_audiofile.wav -i s_videofile.avi f_videofile.mpg

avi to mpeg (for dvd players)

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -target pal-dvd -ps 2000000000 -aspect 16:9 f_videofile.mpeg

ps 2000000000 is the maximum size for the output file in bits hence it is 2 GB here.

Compress avi to divx

chankey@linuxstall:$ ffmpeg -i s_videofile.avi -s 320x240 -vcodec msmpeg4v2 f_videofile.avi

Compress Ogg Theora to mpeg dvd

chankey@linuxstall:$ ffmpeg -i s_videofile.ogm -s 720x576 -vcodec mpeg2video -acodec mp3 f_videofile.mpg

Ubuntu for Android

ubuntu on android

ubuntu on android

Now you can install Ubuntu on your Android phone. Canonical has announced Ubuntu for Android which will provide a full Ubuntu desktop experience on the Android phones. It will work in the same way it works on your PC. Your Android phone will work same as other Android phones but when you connect it to a dock with a monitor, you can see the Ubuntu desktop on the attached monitor.

The user interface is same (Unity) and several free applications are available to access easily. The important thing and the main feature is the consistency of data and other services between Ubuntu and Android environments which includes unified contacts, messages and call through the desktop, synchronized calendars and social media integration.

Since both operating systems share the same kernel so there will be no such issues like “an Ubuntu application running atop Android or vice versa”. Both applications will run at the same time on the same device which gives a great performance.

Mark Shuttleworth said:

The desktop is the killer-app for quad-core phones in 2012. Ubuntu for Android transforms your high-end phone into your productive desktop, whenever you need it.

He also said that they are aiming about 200 Million Users in 4 years.

Summary of features

  • Complete desktop solution for full productivity on docked Android phones
  • Easy to integrate with existing Android phones in development
  • Certified apps for business users from Adobe, Citrix, VMWare and more
  • Drives sales of multi-core phones with faster CPUs, more cores, more RAM and high-end graphics
  • Drive adoption of 4G handsets since office apps shine with low latency and higher bandwidth
  • Canonical leads in ARM Linux support, co-creator of Linaro with ARM
  • Target the enterprise thin client, and emerging market first-PC markets
  • Ubuntu and Android share the same kernel, running at the same time, accessing data and applications
  • The world’s favourite free desktop fully integrated with the world’s favourite open phone

Requirements

If you want to install Ubuntu on your Android phone then your Android must have at least 1 GHz processor, dual-core CPU, 2 GB free space, shared kernel driver, X driver, HDMI support and 2 GB RAM.

Apache 2.4 released: nginx you listening??

apache 2.4

Apache 2.4 released! After six years this one is the major release. First release 2.4.1 is out for download, this is not just another patch to deploy. Apache or httpd is the most popular and widely used web server. 400 million websites are breathing over Apache web server. Have a look at what they have to say about new features in Apache 2.4:

New features include Loadable MPMs, major improvements to OSCP support, mod_lua, Dynamic Reverse Proxy configuration, Improved Authentication/Authorization, FastCGI Proxy, New Expression Parser, and a Small Object Caching API.

Apache HTTP server, the new version, has a plump for cloud this time. The prime area of improvement is performance. The 2.4.x is using less resources and concurrency is better than previous version. All users ever wanted was a faster web browser, this one can rule them all.

Other areas of improvement would be flexibility in configuration and a stronger security check (read authentication and authorisation). The new-features-list is here.

There is a news all over that Apache 2.4 is “direct aim at nginx”. It came out due to the sudden popularity of ngnix for its scalability and performance. Many of them switched permanently to nginx. This new release is an attempt to win them back as this one is incredibly fast..challenging nginx in the face. More on it, later.

Lets hear it from you, what do you think:

httpd or nginx?

Feature Freeze on February 16th

On February 16th of this month Ubuntu development team hit Feature Freeze. Feature Freeze is a point where the developers stop introducing new features, packages, APIs. From this point they start concentrating on fixing bugs in the development release to solidify the included features and making the development release more stable and secure.

ubuntu LTS cycle

At the Ubuntu Developer Summit in November 2011 Canonical announced that the default download for Ubuntu 12.04 will be 64-bit (32-bit version will also be available as a user choice though).

Note: The Ubuntu 12.04 ISO image size is 750 MB, that means it cannot be burned on a CD (which can carry only 700 MB) hence you will have to go for either a DVD or USB drive.

New features and updates in Ubuntu 12.04

1. Much faster start up time for Ubuntu Software Center
2. Refinements in Unity
3. Replacement of Banshee with Rhythmbox
4. Tomboy note-taking application will be removed
5. Mono framework will also be removed

The main feature of Ubuntu 12.04 will be the HUD (Head-Up Display). By this HUD feature application menu items can be accessed right from your keyboard, without the need for using the mouse (hotkey searching).

Adding to the HUD feature Shuttleworth said:

HUD will ultimately replace menus in Unity applications but for Ubuntu 12.04 at least the menus will remain.

7. MyUnity

MyUnity is an independent configurator for Unity, a small system utility for Ubuntu, that can handle the customization of the Unity Launcher, Dash and Panel. Canonical accepted the MyUnity project in their default software repositories and it will be available to all users starting with the Ubuntu 12.04 LTS (Precise Pangolin).

VLC 2.0 twoflower released

Open source media player, one of the greatest, VLC has reached version 2.0. This one is a major upgrade for vlc. According to just-in-report several hundred bugs are removed from previous versions.

What freaks me out is itself being an open-source project, no downloads for linux are being provided on official website. A link to its source is given, fair enough, but the link is returning 404 error (in India). And then we complain why people are still stuck on non-linux operating systems. There you go!

See whats new in all new vlc 2.0 Twoflower on official page.

Edit: Looks like they made a typo, you can build it yourself from source.

Arch Linux Cannot Open Firefox and other applications

arch linux logo

A little bummer for Arch linux lovers, those who have updated their systems lately might face a temporary issue. This problem is restraining users from invoking some applications including firefox and chromium. Issuing a command to run “few” applications will welcome you with following error:

libpng14.so.14: cannot open shared object file: No such file or directory

See what Arch Linux has got to say about this:

Recent releases of libpng and libtiff have required a rebuild of all packages that depend on them; these have just been moved from [testing] to the main repos. As usual, remember to fully update your system and check your unofficial packages (especially the cairo-* packages from AUR) for required rebuilds.

To get through this, you need to rebuild some packages, run following command to see which ones need the updating:

pacman -Qm
