Open Source for Public Cloud

This is the century of CLOUD technology after virtualization passed throught. And there is many software are building and developing for cloud computing and also each manufacturer/vendor also preparing himself for cloud technology. 

OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

Open Stack provided:

OpenClos

What is OpenClos?

"OpenClos is a set of Python scripts and libraries that have been written to automate the creation of IP Fabrics in the data center. OpenClos has been developed as an open-source project and lives on GitHub. OpenClos takes a set of inputs that describe the shape and size of a data center and it outputs network switch configuration files and even a cabling plan.

One of the major design tenets of OpenClos is that everything should be abstracted. You can easily add new network switch devices into your IP Fabric using templates. The same template architecture can be used to add new functionality to an IP Fabric such as multicast, VTEP parameters, or any company standards such as message of the day (MOTD) or users and groups."

OpenClos is mainly design for BGP, and to build IP Fabric, like software-as-a-service (SaaS) or software-defined networking (SDN). OpenClos creates and automates the implementation of an IP Fabric, and everything will be in detail in IP Fabric.

Viber switched off billing for Nepal

"In response to the earthquake in Nepal we have switched off Viber Out billing so Nepalese users can call any destination for free. We hope this will prove helpful to Nepalese users during this difficult time."

Who is Cisco?

 

Cisco Systems was founded in December 1984 by Leonard Bosack, who was in charge of the Stanford University computer science department's computers, Sandy Lerner, who managed the Graduate School of Business' computers, and Richard Troiano.
Despite founding Cisco in 1984, Bosack, along with Kirk Lougheed, continued to work at Stanford on Cisco's first product. It consisted of exact replicas of Stanford's "Blue Box" router and a stolen^[8] copy of the University's multiple-protocol router software. The software was originally written some years earlier at Stanford medical school by research engineer William Yeager. Bosack and Lougheed adapted it into what became the foundation for Cisco IOS. On July 11, 1986, Bosack and Lougheed were forced to resign from Stanford and the university contemplated filing criminal complaints against Cisco and its founders for the theft of its software, hardware designs and other intellectual properties. In 1987, Stanford licensed the router software and two computer boards to Cisco

 

Cisco (NASDAQ: CSCO) is the worldwide leader in IT that helps companies seize the opportunities of tomorrow by proving that amazing things can happen when you connect the previously unconnected.

At Cisco customers come first and an integral part of our DNA is creating long-lasting customer partnerships and working with them to identify their needs and provide solutions that support their success.
The concept of solutions being driven to address specific customer challenges has been with Cisco since its inception. Husband and wife Len Bosack and Sandy Lerner, both working for Stanford University, wanted to email each other from their respective offices located in different buildings but were unable to due to technological shortcomings. A technology had to be invented to deal with disparate local area protocols; and as a result of solving their challenge - the multi-protocol router was born.
Since then Cisco has shaped the future of the Internet by creating unprecedented value and opportunity for our customers, employees, investors and ecosystem partners and has become the worldwide leader in networking - transforming how people connect, communicate and collaborate.

Programming on Linux

Most Linux distributions support dozens of programming languages. The original development tools used for building both Linux applications and operating system programs are found within the GNU toolchain, which includes the GNU Compiler Collection (GCC) and the GNU build system. Amongst others, GCC provides compilers for Ada, C, C++, Go and Fortran. Many programming languages have a cross-platform reference implementation that supports Linux, for example PHP, Perl, Ruby, Python, Java, Go, Rust and Haskell. First released in 2003, the LLVM project provides an alternative cross-platform open-source compiler for many languages. Proprietary compilers for Linux include the Intel C++ Compiler, Sun Studio, and IBM XL C/C++ Compiler. BASIC in the form of Visual Basic is supported in such forms as Gambas, FreeBASIC, and XBasic, and in terms of terminal programming or QuickBASIC or Turbo BASIC programming in the form of QB64.
A common feature of Unix-like systems, Linux includes traditional specific-purpose programming languages targeted at scripting, text processing and system configuration and management in general. Linux distributions support shell scripts, awk, sed and make. Many programs also have an embedded programming language to support configuring or programming themselves. For example, regular expressions are supported in programs like grep, or locate, while advanced text editors, like GNU Emacs, have a complete Lisp interpreter built-in.
Most distributions also include support for PHP, Perl, Ruby, Python and other dynamic languages. While not as common, Linux also supports C# (via Mono), Vala, and Scheme. A number of Java Virtual Machines and development kits run on Linux, including the original Sun Microsystems JVM (HotSpot), and IBM's J2SE RE, as well as many open-source projects like Kaffe and JikesRVM.
GNOME and KDE are popular desktop environments and provide a framework for developing applications. These projects are based on the GTK+ and Qt widget toolkits, respectively, which can also be used independently of the larger framework.

smartphone

 

Devices that combined telephony and computing were first conceptualized by Theodore Paraskevakos in 1971 and patented in 1974, and were offered for sale beginning in 1993. He was the first to introduce the concepts of intelligence, data processing and visual display screens into telephones which gave rise to the "smartphone." In 1971, Paraskevakos, working with Boeing in Huntsville, Alabama, demonstrated a transmitter and receiver that provided additional ways to communicate with remote equipment, however it did not yet have general purpose PDA applications in a wireless device typical of smartphones. They were installed at Peoples' Telephone Company in Leesburg, Alabama and were demonstrated to several telephone companies. The original and historic working models are still in the possession of Paraskevakos.

The first mobile phone to incorporate PDA features was an IBM prototype developed in 1992 and demonstrated that year at the COMDEX computer industry trade show. A refined version of the product was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. The Simon was the first cellular device that can be properly referred to as a "smartphone", although it was not called that in 1994.^[7][8][9] In addition to its ability to make and receive cellular phone calls, Simon was able to send and receive faxes and emails and included several other apps like address book, calendar, appointment scheduler, calculator, world time clock, and note pad through its touch screen display. Simon is the first smartphone to be incorporated with the features of a PDA.
The term "smart phone" first appeared in print in 1995, for describing AT&T's "PhoneWriter Communicator" as a "smart phone"
