Any Linux user would know the importance and usefulness of porting. Here are 10 examples!
The Linux kernel and distributions based on it have often been ported to suit various hardware architectures. These can often be useful for development of projects and testing of apps. This makes them useful for developers.
1. Aleph ARMLinux for RISC OSThis is an ARM Linux release that is based on the Debian distribution. It is available on three CDs. 2. ARM EABI PortThe ARM EABI port is the default port in Debian for the ARM architecture, named armel. The old (OABI) port (named "arm") was last released with 5.0.x (Lenny). An even newer port targeted at newer hardware with another ABI ("armhf") is currently under development and is expected to ship with 7.0 (Wheezy) - see ArmHardFloatPort.3. ARM LinuxARM Linux is a port of the successful Linux Kernel to ARM processor based machines, lead mainly by Russell King, with contributions from many others. ARM Linux is under almost constant development by various people and organisations around the world. It has been ported for over 500 different machines.4. Debian ARM ProjectThis is a port of the Debian distribution for ARM-based machines. While it runs on Corell's Netwinder, this port is expected to be running on other ARM-based architectures and machines too.5. PLEBThe PLEB project relates to building hardware and software infrastructure for research and applications implementation. The project was started in 1998 by then undergrauate student Adam Wiggins. A small portable device was developed, along with the necessary infrastructure for the development of both applications and implementation of research ideas. Since then, PLEB 2 (a second-generation device with a more modern processor), and several applications and add-on daughtercards have been implemented.6. uClinux/ARMThe original uClinux was a derivative of Linux 2.0 kernel intended for microcontrollers without Memory Management Units (MMUs). However, the Linux/Microcontroller Project has grown both in brand recognition and coverage of processor architectures. Today's uClinux as an operating system includes Linux kernel releases for 2.0 2.4 and 2.6 as well as a collection of user applications, libraries and tool chains.7. ART LinuxAdvanced Real-Time Linux (ART-Linux) is a hard real-time kernel developed with robotics applications in mind. Real-Time is accessible from user level and does not require special device drivers. 10 micro-second periodic execution is possible on a PII.8. Axis Linux/ETRAXThe Linux/ETRAX port is based on the 2.0.38 Linux kernel. It is also using the uClinux patches for MMU-less Linux.9. KURTThe Kernel and User Systems Programming (KUSP) work at the University of Kansas has a long history of research in a wide variety of areas relating to the design, implementation, modeling and performance evaluation of computer system components at both the user and kernel levels. Specific projects have varied over time, including improving native Linux support for real-time computations (UTIME and KURT-Linux), high performance emulation and simulation of ATM/TCP/UDP networks (PNNI and Proteus), tool support for network performance evaluation (Netspec), customized programming model support for sets of software agents negotiating resource allocation (ANTS), a unified programming model for computations implemented at both the hardware and software levels (Hybrid Threads), tools and Linux kernel modifications supporting highly configurable computation oriented scheduling and creation of customized programming models (Group Scheduling), and tools supporting fine-grain performance evaluation of user and kernel level computational activity in end-systems (Data Streams), and distributed systems (Global Time Line Construction).10. L4LinuxL4Linux is a port of the Linux kernel to the L4 ยต-kernel API. It is a (para-)virtualized Linux running on top of a hypervisor, completely without privileges if wanted.

Gaming, security, anonymity and many other solutions are provided by these Linux-based OSs.
When you talk about Linux distributions, things like Ubuntu, Fedora, Debian and other rule the roost. But, the Linux kernel has indeed been used for a lot of other purposes. The whole idea of OSs tailored to a particular type of usage has extended beyond imagination. Here are a list of Linux distros that will suit a variety of uses.
1. AsteriskNOWAsteriskNOW makes it easy to create custom telephony solutions by automatically installing the "plumbing." It's a complete Linux distribution with Asterisk, the DAHDI driver framework, and, optionally, the FreePBX administrative GUI. Much of the complexity of Asterisk and Linux is handled by the installer, the yum package management utility and the administrative GUI. With AsteriskNOW, application developers and integrators can concentrate on building solutions, not maintaining the plumbing.2. BakAndImgCDBakAndImgCD is a small Linux-based operating system, which has been designed to perform the following two tasks: data backup (the supported filesystems are: btrfs, ext2, ext3, ext4, FAT, HFS, HFS+, jfs, Minix, NTFS, ReiserFS, and XFS) and disk imaging (using Partimage, Partclone and GNU ddrescue).

Open Source and Cloud Computing together can be the most lethal combination. It's a mixture of functionality with easy availability!
Open source and cloud computing are two of the biggest buzzwords in the technology world nowadays. While open source software, starting with operating systems like Android to network monitoring etc. are at the forefront of many enterprises, cloud computing makes for an essential part of almost all of them. Let's look at an amalgamation of the two though. Here are some open source cloud management tools that you may use!
Hypervisor: In the world of cloud computing, virtual machines are often very important tools. A hypervisor is a software, hardware or firmware that creates and runs these virtual machines. That is why these are also known as Virtual Machine Monitors.1. Xen Hypervisor2. KVM3. OpenVZ4. LguestThese are type 1 hypervisors. Type 1 Hypervisors are those that run directly on a hosts hardware in order to control its resources without requiring additional operating systems.Cloud Management: Cloud management tools can be of various types and qualities. These tools are meant to aid you in managing various activities while using the cloud. These tools are some of the best available in the open source world.1. Juju2. Deltacloud3. jclouds4. Libcloud5.

The Linux terminal has much more to offer than simply typing commands into it. You can master these tricks and become adept at using the Bash shell, which is used as default on majority of Linux distributions. So here are seven tricks that have been outlined below mainly for the less experienced users.
1. Tab Completion – This helps in saving time and is quite useful if you are unsure about a file or a command’s precise name. For instance, if there is a file with a really lengthy name and you want to delete it, you will need to type the file name escaping the space characters properly i.e you need to (insert the \ character before each space).If you type rm r and press Tab, the Bash will instantly fill the file’s name for you. In case of many files beginning with the letter r, Bash will not be able to identify the one you need. 2. Pipes – This allows you to send the output of a command to a different command. According the UNIX every program is a small utility, which specializes in doing one thing. For instance, the ls command is used to list the files in the current directory and the grep command is used for searching its input for a specific term.If you combine these with pipes then you can conduct search for a file in the current directory. ls | grep word3. Wild Cards - The * character (the asterisk) is a wild card that can be used for matching anything. For instance, if you wish to delete both the long file name and we wanted to delete both the “really long file name” and “really very long file name” from the current directory, you can run the command:rm really*name4. Output Redirection - The > character can be used to redirect a command’s output to a file in place of another command. For instance, the line below runs the ls command to list the files in the current directory. However, in place of printing that list to the terminal, it prints the list to a file named “file1” in the current directory:ls > file15. Command History – The Bash can recall a history of the commands typed into it. You can make use of the up and down arrow keys for scrolling through the commands that have been used by you recently. The history command prints out a list of these commands to pipe it to grep to search for commands used recently.~, . & ..The ~ character called the tilde symbolizes the current user’s home directory. In place of typing cd /home/name for going to home directory, you can type cd ~ instead.6. Run a Command in the Background – As a standard Bash executes each command that is run by you in the current terminal. It’s okay but what about when you want to launch an application and continue using the terminal. By typing firefox for launching Firefox, this will take over your terminal and show error messages and other output till you close it. By adding the & operator to the end of the command for allowing Bash to execute the program in the background use:firefox &7. Conditional Execution – Bash can be used for running two commands in sequence. The second command can only be executed once the first command is completed successfully. For doing this you need to put both commands on the same line and separate it by a &&, or double ampersand.For instance, the sleep command obtains a value in a matter of a few seconds, counts down, and completes successfully. It’s not useful by itself but can be used for running another command after a delay. The command given below will wait for five seconds and launch the gnome-screenshot tool:sleep 5 && gnome-screenshot

There’s good news for Linux Mint fans. A release candidate for Linux Mint 17, Quiana, is now available for download. The long term release of the new version of the Ubuntu-based distro, which emphasises on ease of use, will also be out soon and will be officially supported till 2019. Mint is known for its easy installation of media codecs and variety of desktop environments, which resemble the classic Windows interface unlike the Unity UI that is part of the most recent versions of Ubuntu.
The release candidate is available with Cinnamon or MATE desktop environments. It is quite stable but since it’s not the long term release, there may be some glitches. The users have a chance to report or fix bugs in the system.Right now, the known issues include no support for Optimus graphics, which help in switching between systems that hold Nvidia graphics cards. In addition, the release candidate’s login screen freezes if the default language is changes to German. While it is not sure whether the graphics card issue will be solved, the language issues should be sorted in the long term release.The cinnamon and MATE desktops resemble Windows through the taskbar at the bottom of the screen and an app menu that can be launched from the lower left corner of the screen. While Cinnamon is a new UI that has been developed by the Mint team, MATE is based on the GNOME 2 desktop environment. However, MATE is no longer under development.The new version of the distro includes improvements in the update and driver managers, new artworks and updated login screens. In addition, Cinnamon now supports displays that have high pixel densities.As reported earlier, Mint will now follow a new release strategy, basing itself only on the Ubuntu LTS releases. LTS releases of Ubuntu come out once in two years, with 5 years of official support.
Linux Foundation offers an edX development course, which follows the lines of massive open online course (MOOC) platform. The course is developed by MIT and Harvard Universities.
The Linux Foundation will offer a Linux development course on edX, on the lines of the massive open online course (MOOC) platform, which is developed by the Massachusetts Institute of Technology and Harvard University. The move is part of an edX effort to expand its course offerings to include content from non-academic institutions.
MOOC will offer the same material that is taught in its introduction to Linux class. It content is designed for people with little to no-experience in Linux open-source OS. People can start taking the MOOC, this summer, while the precise date will be declared, next month.
The Linux class will be free and available to anyone with a Web connection. However, the foundation normally charges $ 2,500 for the course that is already taught online and in person via authorized training partners.
Previously, all edX content came from the Linux Foundation’s 32 member schools that include University of California, (Berkeley), Dartmouth College and McGill University.
The non-academic institutions that will join the edX exercise include International Monetary Fund, The Smithsonian Institution and Inter-American Development Bank. Seven academic institutions that joined edX members are from the likes of Colgate University, Hamilton College and Open Courseware Consortium.
According to PC World, Linux Foundation director, Jim Zemlin, noted that the OS helps run stock exchanges, Android smartphones and many cloud computing services. EdX courses offer an affordable and easy way to help solve the Linux talent shortage.
He said, “Linux has just seen this insane adoption across every sector of technology,” he said. “That’s all great but as use of Linux rises we need to keep up with demand. This is a way for people to get familiar with Linux.”
Anant Agarwal, president of edX, said, “Many of our students are looking for courses on topics that enable them to get a better job or bridge skill gaps, and Linux is one example. A verified certificate from the Linux Foundation would have a lot of credibility in the marketplace.”
