Mozilla Announces First Beta Release Of Persona

Persona is finally ready for use. Today, Mozilla is going to announce the first public beta release of Persona, a login management system that eliminates per-site passwords in websites while being safe, secure and easy to use. Mozilla Persona is a completely decentralized and secure authentication system for the web based on the open BrowserID protocol. To get started with Mozilla Persona, you'll have to signup here. FYI, Persona was first introduced as BrowserID.

Persona is now ready to use for authentication and will be available from today to the public as the first beta release. It works in all major smartphone, tablet, and desktop browsers and the user experience has been thoroughly reviewed and polished.

Available in more than 25 languages, Persona does not need any API keys and it will always remain free. Persona is an open source project and you can easily use persona with your site. Persona is safe, secure, and built on top of public key cryptography. Instead of a password, the user's browser generates a cryptographic "identity assertion" that expires after a few minutes and is only valid on a single site. Because there are no site-specific passwords, websites using Persona don't have to worry about securely storing or potentially losing a password database.

The sites such as OpenPhoto and Times Crossword are already using Mozilla Persona in their websites.

Persona is built upon BrowserID protocol. Once popular browser vendors implement BrowserID, they will no longer need to rely on Mozilla to log in. You can easily integrate Persona in few minutes. Persona is already getting integrated in different applications.

Lets see how successful will be Mozilla Persona, its success depends upon the adoption by websites and applications and then the subsequent use by the users.

Things To Do On The Ocassion Of Software Freedom Day

If you are FOSS enthusiast then you are possibly seeking for some ideas to celebrate Software Freedom Day in different way. I have come up with some ideas I could think of doing on the ocassion of software freedom day today.

Software Freedom Day (SFD) is annually celebrated on the third saturday of September with the aim of increasing awareness of Free Software and its virtues, and encouraging its use. SFD was first observed in 28^th of August back in 2004 and since 2006, it is observed on the 3^rd saturday of september. Software Freedom International acts as the central legal body for organizing software freedom day and each local team is responsible for organizing the local chapters of Software Freedom Day.

Software Freedom Day is not just about attending an event that is organized locally in your area. Rather, you can do anything that hits your mind to celebrate software freedom day. Below are some of the ideas in my mind.

• Attend local SFD events
You can attend the local SFD events being organized today. You can find the local events through SFD 2012 events map. Locate the nearby event and attend it. Maybe you will find someone to discuss with :)


• Listen to the SFD and other FOSS songs
Download the SFD song or FSF song on your favorite music gadget and listen to them the whole day. You can also listen the musics at MUSOpen.org.


• Listen to the free audio and video speeches from FSF and GNU
You can listen to several audio and video speeches related to the free software foundation and GNU movements which are available at audio-video.gnu.org. Quite a good way to pass the time while getting to know about FSF, GNU and related events.


• Watch some open source movies and documentaries
You can download and watch the open-source or free-content films for time pass. You can also watch the movies and documentaries. Some of them are Revolution OS, Freedom Fry, The Codebreakers, Code Rush, Still This 1, Still This 2, The Code, Arduino documentary and few others you can find on net. If you got any suggestions, do drop them as comments.


• Run an install fest anywhere possible
You could run the installation fest and help your friends and relatives install different linux distros. It can be anywhere. I mean anywhere. You can do it in your own home, in your school, and in your office. After all, its fun to motivate your friends and relatives to use open source softwares if they are not already using them. Literate the people who are around you. Believe me its fun.


• Try finding bug on some open source softwares
Grab some open source softwares; it can be desktop app or web app. Try finding bugs or errors in them and report them. You have just helped to improve one of the open source softwares and your contribution will be counted for sure :). If you are geek enough, try finding some critical bugs and vulnerabilities. It can be kind of tough and challenging task but its always fun to do so.


• Do some blogging about software freedom and free and open source softwares
If you got your own blog or website, make some entries related to software freedom. You could include the event you just visited or you could discuss about the free and open source softwares available in the market. If you don't have blog already, start today. Its a good day itself to start blogging on open source softwares.


• Write some code snippets and useful little softwares
If you are a good programmer, why not write and distribute the small software projects by today itself. You could do small stuffs like command line file transfer app, nepali calendar or anything you can think of. Try to develop some local software that will be useful for you and your community.


• Join any beginner IRC channel and help the beginners
Search for some IRC channels in freenode or other networks and try helping the beginners. You can preferably choose the IRC channels related to linux, programming, hacking, and open source softwares and then dedicate some hours of your day to help other people.


• Donate some amount to your favorite open source softwares
Got some bucks to spare? Why not donate some amount to your favorite open source software. This can be very motivating to the developers of open source softwares.

Any other idea that hits your mind? Share as the comment :)

And at last, happy software freedom day to all the freedom lovers :)

How To Find The Location Of Command In Linux

Sometimes you need to find the pathnames or locations of commands you use frequently. In this post, I am going to discuss two useful commands that are useful for locating Linux commands.

The first command to locate the Linux commands is which. This command returns the pathnames of the files or links. However, it does not follow the symbolic links.

samar@Techgaun:~$ which bash
/bin/bash

You can also find the pathnames of multiple commands at once using which command.

samar@Techgaun:~$ which -a bash cat ls iftop
/bin/bash
/bin/cat
/bin/ls
/usr/sbin/iftop

The other command is type command which is useful to determine if a command is an alias, a built-in command or an independent command.

samar@Techgaun:~$ type gedit
gedit is /usr/bin/gedit
samar@Techgaun:~$ type grep
grep is aliased to `grep --color=auto'
samar@Techgaun:~$ type -t iftop
file

You can play more with the type command. I hope this helps :)

How To Fix Bootmgr Missing In UNetBootin

Sometimes while working with the LiveUSBs using UNetBootin, you might face the issue that says the Bootmgr is missing and it also says, Press Ctrl + ALT + DELETE TO Restart. This post will help you to fix this particular issue.

First off, format your USB as a FAT32 since it happens commonly because your USB drive is formatted as NTFS and UNetBootin seems to have issues with NTFS filesystems. If formatting to FAT32 also does not work, then try formatting as FAT filesystem.

If you still get boot errors from USB, it is possible that the partition is not marked as active. Assuming you're on windows, you can use the diskpart tool to make the partition active. See the process below:

list disk

The above command will display the disks and their sizes as well. Choose the appropriate disk as below:

select disk 1

Replace the value 1 in above command to select the correct USB drive. Then again list the partitions but usually you can select the partition for USBs as below and then activate it:

select partition 1
active

The active command will mark the currently selected partition as active. Now reboot and enjoy booting from LiveUSB.

How To Enable Native PDF Viewer In Firefox 15

Firefox 14 added a native HTML5 and javascript based PDF reader to read PDF files within the browser but it is disabled by default in Firefox 15 since it is not totally ready. If you don't mind few minor glitches, you can experience the native PDF viewer in Firefox 15 through about:config

Browser developers are integrating many functionalities in the browsers themselves. PDF viewer is no exception and Mozilla is still working for fully functional PDF viewer based on HTML5 and javascript which is called as pdf.js. Pdf.js is still in Beta phase and Mozilla has not declared it as 100% usable so it is disabled by default in firefox 15.

Type about:config in the URL bar (and ignore warning if it appears). Then search for pdfjs. A particular preference pdfjs.disabled will be listed on the search result whose value is by default set to true.

You will just need to double click on this preference row and it will be set to false. This will enable the native PDF viewer in Firefox 15.

You'll possibly have to restart your browser to see the effect in action.

I have been using the native PDF viewer and haven't faced any glitches or problem still. I hope this is helpful :)
