10 Ubuntu Flavours You Should Know

The most popular Linux OS has been known to have given birth to some the most loved OSs, including the fourth most popular OS in the world.    Rate this news:      If you look at the OS market, the name following Windows as Linux is the Ubuntu OS. While Windows rules the roost, Ubuntu has over the years, gone on to become the third most used OS in the world. With a tagline that says, "Linux for humans," Ubuntu is easy to use, powerful and an apt replacement for Windows. So, naturally, developers got together and built on top of this OS, bringing new distros. It is worth taking a look at these. 1. Mint The purpose of Linux Mint is to produce a modern, elegant and comfortable operating system which is both powerful and easy to use. Started in 2006, Linux Mint is now the 4th most widely used home operating system behind Microsoft Windows, Apple Mac OS and Canonical's Ubuntu. 2. Kubuntu This is an open source alternative to Windows and MS Office. Kubuntu is an operating system built by a worldwide team of expert developers. It contains all the applications you need: a web browser, an office suite, media apps, an instant messaging client and many more. 3. Edubuntu Edubuntu is a grassroots movement that aims to get Ubuntu into schools, homes and communities and make it easy for users to install and maintain their systems. It is built by a team of hacker, students, teachers etc. 4. Xubuntu Xubuntu is an easy-to-use operating system. It comes with Xfce, which is a stable, light and configurable desktop environment. It is perfect for those who want the most out of their desktops, laptops and netbooks with a modern look and enough features for efficient, daily usage. Moreover, it works on older hardware as well. 5. Gobuntu Gobuntu 8.04.1 is the final release of Gobuntu. The project has merged back to mainline Ubuntu, so there is no need for a separate distribution. It tries to provide the Free Software Foundation’s four freedoms and tries to lay a platform for other free software. 6. Ubuntu Studio Ubuntu Studio is a free and open source operative system, and an official flavor of Ubuntu. Ubuntu Studio is the most widely used multimedia orientated GNU/Linux distribution in the world. It comes preinstalled with a selection of the most common free multimedia applications available, and is configured for best performance for the Ubuntu Studio defined workflows: Audio, Graphics, Video, Photography and Publishing. 7. Mythbuntu Mythbuntu is an official Ubuntu flavor focused upon setting up a standalone MythTV based PVR system. It can be used to prepare a standalone system or for integration with an existing MythTV network. Unlike similar projects, Mythbuntu keeps close ties with Ubuntu and all development is given back to Ubuntu. This architecture allows simple conversions from a standard desktop to a Mythbuntu machine and vice versa. The development cycle of Mythbuntu mirrors that of Ubuntu. 8. Ubuntu Server Edition The Ubuntu Server Edition is a platform for scale-out computing. It helps you make the most of your infrastructure. Whether you want to deploy an OpenStack cloud, a Hadoop cluster or a 50,000-node render farm. 9. Eeebuntu Now known as the Aurora project, this Ubuntu flavour started life originally in 2008 as the Eeebuntu project. This was a customised redistribution of Ubuntu, which was modified specifically for the Eeepc range of netbooks. What was originally a simple collection of scripts and hacks to get Ubuntu 8.04 onto an EeePC it has grown into a distribution of its own. 10. Ubuntu Mini Remix Ubuntu Mini Remix is a fully working Ubuntu live-CD containing only the minimal set of software to make the system work. Ubuntu Mini Remix ISO image is around 200MB.

Here Are The Top Techniques To Hack A Facebook Account Password

These tricks are some of the more preferred choices of hackers around the world to hack into a Facebook account!     Social networking giant Facebook is indeed a giant of sorts in the recent times. With more and more people using the platform to connect with their near and dear ones, the chances of being hacked have also gone haywire. Hackers could make use of either of the following tricks to get through your account for their vested interests. Beware! 1.Phishing Phishing is the attempt to sabotage sensitive information such as usernames, passwords, and credit card details by posing as a trustworthy entity in an electronic communication. These entities normally range from popular social web sites, auction sites, banks, online payment processors to IT administrators. Phishing is normally carried out by means of email spoofing/instant messaging (emails used in the process usually carry links to websites that have been infected with malware.). These spoofed emails/messages usually direct the users to a separate however extremely genuine looking website where they might be asked to re-enter their account information. These genuine-looking websites are in fact fake/scams in disguise and lure users into submitting their sensitive information. Once through, users' account gets hacked! 2.Keyloggers/RATs Keyloggers are essentially a surveillance tool often used by employers to ensure employees use work computers for business purposes only. However, with time hackers have come to make good use of the tool for their own vested interests. The process of keylogging becomes particularly effective if the miscreant somehow gains physical access to the victim's computer. All that a hacker needs to do now is to install a keylogger into the victims's computer and direct the same to his/her destination. The keylogger will now record all the victim's keystrokes into a log file and send it to the destination chosen by the hacker. The hacker can then use these logs to acquire the victims's account information and hack into it. 3.Primary Email address This is quite an obvious way for hackers to get through your Facebook accounts. If a hacker is able to somehow hack into your primary email address what you're also using to log into Facebook, well, it's a walk in the park for him/her after that. The hacker can easily use Facebook's 'Forgot password' trick to make the social networking site to send the victim's password to the designate primary email account, that unfortunately has already been compromised. 4.Social Engineering Social Engineering is the psychological manipulation of people into performing actions or divulging confidential information. This will eventually depend upon the hacker's logical expertise. It could involve a probable guessing of the password based on the victim's Facebook and other social networking profiles.

10 Most Bizarre Programming Languages Ever!

If you thought that programmers can’t have a sense of humour, then take a look at these programming languages. These are a few most strangely named programming languages.      Programming languages aren’t always meant to write complex codes. Sometimes programmers develop languages that aren’t meant to be used for high level coding. There are some truly bizarre programming languages, which fall under the Esoteric Programming Language or Esolang category. These are languages that have been developed to test a programmers ideas or simply as a joke. Real world usability is perhaps the last things on the developer’s mind in this case. INTERCAL: Creators Donald R. Woods and James M. Lyon wanted to create a programming language, which had no similarity to any existing language. The authors say that “the full name of the language is Compiler Language With No Pronounceable Acronym, which for obvious reasons, abbreviated INTERCAL”. The language was developed in 1972 and it uses redundant and cryptic syntax for simple operations. It’s user manual has directions like, “Caution! Under no circumstances confuse the mesh with the interleave operator, except under confusing circumstances!” The program’s compiler rejects a program if the program doesn’t have enough PLEASE modifiers and it also uses statements like FORGET and IGNORE. Whitespace: This is an esoteric language, which uses whitespace characters for its syntax. The language was designed by Edwin Brady an Chris Morris on April Fool’s Day 2003. Chef: Programs in this language look like cooking recipes. It was designed by David Morgan-Mar in 2002. Stacks in this language are called mixing bowls or baking dishes, while the instructions that manage the stacks are said to be mixing or stirring. Velato: This language uses MIDI files as its source code. The programs are defined by the pitch and order of notes. The programs in this language can be represented on paper as sheets of music. Shakespeare: In this language, your program is presented like a Shakespearean play. The first line of the program is the title, while the variables are declared in the Dramatis Personae. Each of the variables must be named after a character from a Shakespearean play. The language was designed by Jon Aslung and Karl Hasselstrom. Omgrofl: Created in 2006 by one Juraj Borza, this language works on internet slangs. As it evident by the name itself, which is composed of the slangs omg (oh my god) and rofl (rolling on the floor laughing). Variables in this language have to be slangs, like lol, lool, looool and so on. The conditional statement ‘if’ in C is replaced by ‘wtf’ in this language. Piet: It was named after Piet Mondrian, the geometric abstract painter and has been designed by the designer of Chef. Programming is done through colours. Befunge: In this language, the programs are arranged on a two dimensional grid, which is known as the playfield. It was created in 1992 by one Chris Pressey, who wanted to make is as tough as possible to compile a program. Malbolge: If you’ve read Dante’s Inferno, then you would definitely recognise the name of the eight circle of Hell. This programming language was designed in 1998 by Ben Olmstead. This is a step beyond befunge and wants to make it as difficult as possible to write the code itself. The first Malboge program took two years to appear and that too was not written by a human, but a Lisp program. Brainfuck: This is perhaps the most well known esoteric programming language ever created. The language was created in 1992 by Urban Muller who wanted to design a language that could be implemented using the smallest compiler. Compilers of branfuck have been smaller than 200 bytes. It has only eight commands, which are — > < + _ . , [ ].

Apache OpenOffice Vs LibreOffice

We bring you the pros and cons of using Apache OpenOffice and LibreOffice.        Apache OpenOffice and LibreOffice have descended from OpenOffice.org. Over the past couple of years, nearly all Linux distributions have made LibreOffice as their default office suite. But in the past one and a half year, OpenOffice has been relaunched into a newly organized Apache project. This gives free software users two options in place of one. As cited on datamation.com, here’s looking at a comparative of the two apps. Differences in the Apps – Many features in LibreOffice's and OpenOffice's applications are similar. In Draw, there is no difference, in Impress, the main difference being that LibreOffice's latest release includes support for controlling a slide show from an Android device. The selection of slide backgrounds is different between the two and either selection should be sufficient. In case of Writer, the most popular application, the differences are basically in a minor key. In LibreOffice, the status bar at the base of the editing window has a word and character count. Also, LibreOffice's comments can be anchored to paragraphs rather than a single point. LibreOffice also has a simplified Find field, which is the same as that in a web browser. Formats and Fonts –Major differences come under the category of format and font support. For exmple, OpenOffice still supports saving to formats. It can open .docx files, but, unlike LibreOffice, cannot save to it. LibreOffice also offers font support with the latest version supporting OpenType which is the preferred format for modern fonts as it has support for multiple languages and advanced typography. Neither OpenOffice nor LibreOffice interact best with Microsoft formats when a document is mostly text and has a minimum of tables, draw objects, and complex formatting. But in case you want to exchange native and Microsoft formats, LibreOffice has certain advantages. It can not only read and write to recent Microsoft formats, but also does font handling, which removes any need for font substitution. Extension Policies - OpenOffice as well as LibreOffice can support well-rounded collections of extensions that can be downloaded and added within minutes to enhance or change features. In many cases, an extension that can work with one will work with the other too. The difference being in LibreOffice you don’t need to install the most popular extensions as it comes installed with them. They are already enabled or integrated. The extensions include Lightproof, a basic grammar checker; Report Builder for summarizing and printing from data bases; Presentation Minimizer for reducing the size of presentations; Wiki Publisher for blogging, and Presentation Console for delivering slide shows, as well as a number of others. These extensions are available for OpenOffice as well. In OpenOffice, you don’t need to be aware of them and make efforts to locate them. Interfaces in Transition - Both OpenOffice and LibreOffice are suites that come with a robust set of features, but have interfaces that are stuck in the mid-1990s. In the latest version, OpenOffice's has limited its changes to the side bar. This feature has to be specifically enabled in LibreOffice from Tools -> Options -> LibreOffice -> Advance. The sidebar consists of features for manual formatting. At its best, the sidebar is a simplified version of some of the tabs for formatting characters and paragraphs, like Border tab in all applications, and the Format tab for spreadsheet cells. LibreOffice offers the task pane in Impress, while is similar to the sidebar, summarizing many of the steps in slide design in the names of its tabs. However, it is the Writer editing window where many of LibreOffice's interface enhancements have taken place. It has a word and character count in the status bar at the bottom of the window, and the cramped sub-menus for managing and editing templates have been changed with a stream-lined interface in which buttons replace drop-down menus. Making a Choice LibreOffice has a small but a big advantage. While Apache OpenOffice was being formed, LibreOffice got talent around the world who wanted the code. The main advantage for LibreOffice is what can be termed as the license-drain. While the Apache License is compatible with LibreOffice's GNU General Public License, the Less GNU General Public License is incompatible with the Apache License. While LibreOffice can easily borrow code from OpenOffice, OpenOffice cannot borrow from LibreOffice. This situation may vary especially as Apache OpenOffice benefits from huge name recognition in comparison to LibreOffice. Yet LibreOffice has instantly earned wide support and has an active community that has done more in three years than OpenOffice.org managed in twelve
