UBUNTU

Posted on Thursday, October 10, 2013 by Unknown

HISTORY OF UBUNTU




Born in April 2004 and at just under two years old at the time of this writing, a history of Ubuntu may seem premature. However, the last two years have been full ones for Ubuntu. With its explosive growth, it is difficult even for those involved most closely with the project to track and record some of the high points. Importantly, there are some key figures whose own history must be given to fully understand Ubuntu. This brief summary tries to quickly give you the high points of Ubuntu's history to date and the necessary background knowledge to understand where Ubuntu comes from.

Mark Shuttleworth

No history of Ubuntu can call itself complete without a history of Mark Shuttleworth. Shuttleworth is, undeniably, the most visible and important person in Ubuntu. More important from the point of view of history, Shuttleworth is also the originator and initiator of the project—he made the snowball that would eventually roll on and grow to become the Ubuntu project.
Shuttleworth was born in 1973 in Welkom, Free State in South Africa. He attended Diocesan College and obtained a business science degree in finance and information systems at the University of Cape Town. During this period, he was an avid computer hobbyist and became involved with the free and Open Source software community. He was at least marginally involved in both the Apache project and the Debian project and was the first person to upload the Apache Web server, perhaps the single most important piece of server software on GNU/Linux platforms, into the Debian project's archives.
In addition to space exploration and a less-impressive jaunt to Antarctica, Shuttleworth played an active role as both a philanthropist and a venture capitalist. In 2001, Shuttleworth founded the Shuttleworth Foundation (TSF)—a nonprofit organization based in South Africa. The foundation was chartered to fund, develop, and drive social innovation in the field of education. Of course, the means by which TSF attempts to achieve these goals frequently involved free software. Through these projects, the organization has been one of the most visible proponents of free and Open Source software in South Africa and even the world. In the venture capital area, Shuttleworth worked to foster research, development, and entrepreneurship in South Africa with strategic injections of cash into start-ups through a new venture capital firm called HBD—an acronym that stood for "Here Be Dragons." During this period, Shuttleworth was busy brainstorming his next big project—the project that would eventually become Ubuntu.

The Warthogs

There has been no lack of projects attempting to wrap GNU, Linux, and other pieces of free and Open Source software into a neat, workable, and user-friendly package. Mark Shuttleworth, like many other people, believed that the philosophical and pragmatic benefits offered by free software put it on a course for widespread success. That said, none of the offerings were particularly impressive. Something was missing from all of them. Shuttleworth saw this as an opportunity. If someone could build the great free software distribution that helped push GNU/Linux into the mainstream, he would come to occupy a position of strategic importance.
The list is now a familiar list of features to most Ubuntu users. Many of these traits will be covered in more depth later in this chapter. The group wanted
  • Predictable and frequent release cycles
  • A strong focus on localization and accessibility
  • A strong focus on ease of use and user-friendliness on the desktop
  • A strong focus on Python as the single programming language through which the entire system can be built and expanded
  • A community-driven approach that worked with existing free software projects and a method by which the groups give back as they go—not just at the time of release
  • A new set of tools designed around the process of building distributions that allowed developers to work within an ecosystem of different projects and that allowed users to give back in whatever way they could.

What Does Ubuntu Mean?

At this point, the Warthogs had a great team, a set of goals, and a decent idea of how to achieve most of them. The team did not, on the other hand, have a name for their project. Shuttleworth argued strongly that they should call the project "Ubuntu."
Ubuntu is a concept and a term from several South African languages, including Zulu and Xhosa. It refers to a South African ideology or ethic that, while difficult to express in English, might roughly be translated as "humanity toward others," or "I am because we are." Others have described ubuntu as "the belief in a universal bond of sharing that connects all humanity." The famous South African human rights champion Archbishop Desmond Tutu explained ubuntu in this way:
Ubuntu played an important role as a founding principle in post-apartheid South Africa and remains a concept familiar to most South Africans today.

Creating Canonical

With time, the company was named Canonical. The name was a nod to the project's optimistic goals of becoming the canonical place for services and support for free and Open Source software and for Ubuntu in particular. "Canonical" of course, refers to something that is accepted as authoritative. It is a common word in the computer programmer lexicon. It's important to note that being "canonical" is like being standard—it is not coercive. Unlike holding a monopoly, becoming the canonical location for something implies a similar sort of success—but never one that cannot be undone, and never one that is exclusive. Other companies will support Ubuntu and build operating systems based on it—but as long as Canonical is doing a good job, its role will remain central.



Kubuntu



 Kubuntu(/kuːˈbuːntuː/ koo-BOON-too) is an official derivative of the Ubuntu operating system which uses the KDE Plasma Desktop instead of the Unity graphical environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems, every package in Kubuntu shares the same repositories as Ubuntu,[3] and it is released regularly on the same schedule as Ubuntu.[4] It is possible to install both the KDE Plasma Desktop (kubuntu-desktop) as well as the Unity desktop (ubuntu-desktop) on the same machine.
Kubuntu was sponsored by Canonical Ltd. until 2012, and thereafter by Blue Systems. During the changeover Kubuntu retained use of Ubuntu project servers and existing developers



 MEANING OF THE  NAME KUBUNTU


"Kubuntu" means "towards humanity" in Bemba, and is derived from ubuntu ("humanity"). The K at the beginning represents the KDE community on whose platform Kubuntu is built. By coincidence, Kubuntu also means "free" in Kirundi.[6]
“Kubuntu” is a registered trademark held by Canonical.

HISTORY OF WINDOWS

Posted on Thursday, September 26, 2013 by Unknown

            A history of Windows


Hghlights from the first 25 years


1975–1981: Microsoft boots up


Getting started: Microsoft co-founders Paul Allen (left) and Bill GatesGetting started: Microsoft co-founders Paul Allen (left) and Bill Gates

It’s the 1970s. At work, we rely on typewriters. If we need to copy a document, we likely use a mimeograph or carbon paper. Few have heard of microcomputers, but two young computer enthusiasts, Bill Gates and Paul Allen, see that personal computing is a path to the future.

In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision—a computer on every desktop and in every home. During the next years, Microsoft begins to change the ways we work.

The dawn of MS‑DOS


In June 1980, Gates and Allen hire Gates’ former Harvard classmate Steve Ballmer to help run the company. The next month, IBM approaches Microsoft about a project code-named "Chess." In response, Microsoft focuses on a new operating system—the software that manages, or runs, the computer hardware and also serves to bridge the gap between the computer hardware and programs, such as a word processor. It’s the foundation on which computer programs can run. They name their new operating system "MS‑DOS."

When the IBM PC running MS‑DOS ships in 1981, it introduces a whole new language to the general public. Typing “C:” and various cryptic commands gradually becomes part of daily work. People discover the backslash (\) key.

MS‑DOS is effective, but also proves difficult to understand for many people. There has to be a better way to build an operating system.

Geek trivia: MS‑DOS stands for Microsoft Disk Operating System.

1982–1985: Introducing Windows 1.0


The Windows 1.0 desktop

Microsoft works on the first version of a new operating system. Interface Manager is the code name and is considered as the final name, but Windows prevails because it best describes the boxes or computing “windows” that are fundamental to the new system. Windows is announced in 1983, but it takes a while to develop. Skeptics call it “vaporware.”

The fully-packaged Windows 1.0The fully-packaged Windows 1.0

On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0. Now, rather than typing MS‑DOS commands, you just move a mouse to point and click your way through screens, or “windows.” Bill Gates says, “It is unique software designed for the serious PC user…”

There are drop-down menus, scroll bars, icons, and dialog boxes that make programs easier to learn and use. You're able to switch among several programs without having to quit and restart each one. Windows 1.0 ships with several programs, including MS‑DOS file management, Paint, Windows Writer, Notepad, Calculator, and a calendar, card file, and clock to help you manage day-to-day activities. There’s even a game—Reversi.

Geek trivia: Remember floppy disks and kilobytes? Windows 1.0 requires a minimum of 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adapter card. A hard disk and 512 KB memory is recommended for running multiple programs or when using DOS 3.0 or higher.

1987–1992: Windows 2.0–2.11—More windows, more speed


The Windows 2.0 desktop

On December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and expanded memory. With improved graphics support, you can now overlap windows, control the screen layout, and use keyboard shortcuts to speed up your work. Some software developers write their first Windows–based programs for this release.

Windows 2.0Windows 2.0

Windows 2.0 is designed for the Intel 286 processor. When the Intel 386 processor is released, Windows/386 soon follows to take advantage of its extended memory capabilities. Subsequent Windows releases continue to improve the speed, reliability, and usability of the PC.

In 1988, Microsoft becomes the world’s largest PC software company based on sales. Computers are starting to become a part of daily life for some office workers.

Geek trivia: Control Panel makes its first appearance in Windows 2.0.

1990–1994: Windows 3.0Windows NT—Getting the graphics


The Windows 3.0 desktop

On May 22, 1990, Microsoft announces Windows 3.0, followed shortly by Windows 3.1 in 1992. Taken together, they sell 10 million copies in their first 2 years, making this the most widely used Windows operating system yet. The scale of this success causes Microsoft to revise earlier plans. Virtual Memory improves visual graphics. In 1990 Windows starts to look like the versions to come.

Windows now has significantly better performance, advanced graphics with 16 colors, and improved icons. A new wave of 386 PCs helps drive the popularity of Windows 3.0. With full support for the Intel 386 processor, programs run noticeably faster. Program Manager, File Manager, and Print Manager arrive in Windows 3.0.

Windows software is installed with floppy discs bought in large boxes with heavy instruction manuals.

The popularity of Windows 3.0 grows with the release of a new Windows software development kit (SDK), which helps software developers focus more on writing programs and less on writing device drivers.

Windows is increasingly used at work and home and now includes games like Solitaire, Hearts, and Minesweeper. An advertisement: “Now you can use the incredible power of Windows 3.0 to goof off.”

Windows for Workgroups 3.11 adds peer-to-peer workgroup and domain networking support and, for the first time, PCs become an integral part of the emerging client/server computing evolution.

Windows NT


When Windows NT releases on July 27, 1993, Microsoft meets an important milestone: the completion of a project begun in the late 1980s to build an advanced new operating system from scratch. "Windows NT represents nothing less than a fundamental change in the way that companies can address their business computing requirements," Bill Gates says at its release.

Unlike Windows 3.1, however, Windows NT 3.1 is a 32-bit operating system, which makes it a strategic business platform that supports high-end engineering and scientific programs.

Geek trivia: The group that develops Windows NT was originally called the "Portable Systems" team.

1995–2001: Windows 95—the PC comes of age (and don't forget the Internet)


The Windows 95 desktop

On August 24, 1995, Microsoft releases Windows 95, selling a record-setting 7 million copies in the first five weeks. It’s the most publicized launch Microsoft has ever taken on. Television commercials feature the Rolling Stones singing "Start Me Up" over images of the new Start button. The press release simply begins: “It’s here.”

This is the era of fax/modems, e‑mail, the new online world, and dazzling multimedia games and educational software. Windows 95 has built-in Internet support, dial-up networking, and new Plug and Play capabilities that make it easy to install hardware and software. The 32-bit operating system also offers enhanced multimedia capabilities, more powerful features for mobile computing, and integrated networking.

At the time of the Windows 95 release, the previous Windows and MS‑DOS operating systems are running on about 80 percent of the world’s PCs. Windows 95 is the upgrade to these operating systems. To run Windows 95, you need a PC with a 386DX or higher processor (486 recommended) and at least 4 MB of RAM (8 MB of RAM recommended). Upgrade versions are available for both floppy disk and CD-ROM formats. It’s available in 12 languages.

Windows 95 features the first appearance of the Start menu, taskbar, and minimize, maximize, and close buttons on each window.

Catching the Internet wave


In the early 1990s, tech insiders are talking about the Internet—a network of networks that has the power to connect computers all over the world. In 1995, Bill Gates delivers a memo titled “The Internet Tidal Wave,” and declares the Internet as “the most important development since the advent of the PC.”

In the summer of 1995, the first version of Internet Explorer is released. The browser joins those already vying for space on the World Wide Web.

Geek trivia: In 1996, Microsoft releases Flight Simulator for Windows 95—the first time in its 14-year history that it’s available for Windows.

1998–2000: Windows 98, Windows 2000, Windows Me


Windows 98


The Windows 98 desktop

Released on June 25, 1998, Windows 98 is the first version of Windows designed specifically for consumers. PCs are common at work and home, and Internet cafes where you can get online are popping up. Windows 98 is described as an operating system that “Works Better, Plays Better.”

With Windows 98, you can find information more easily on your PC as well as the Internet. Other improvements include the ability to open and close programs more quickly, and support for reading DVD discs and universal serial bus (USB) devices. Another first appearance is the Quick Launch bar, which lets you run programs without having to browse the Start menu or look for them on the desktop.

Geek trivia: Windows 98 is the last version based on MS‑DOS.

Windows Me


The Windows Me media experience

Designed for home computer use, Windows Me offers numerous music, video, and home networking enhancements and reliability improvements compared to previous versions.

First appearances: System Restore, a feature that can roll back your PC software configuration to a date or time before a problem occurred. Movie Maker provides users with the tools to digitally edit, save, and share home videos. And with Microsoft Windows Media Player 7 technologies, you can find, organize, and play digital media.

Geek trivia: Technically speaking, Windows Me was the last Microsoft operating system to be based on the Windows 95 code base. Microsoft announced that all future operating system products would be based on the Windows NT and Windows 2000 kernel.

Windows 2000 Professional


Windows 2000 ProfessionalWindows 2000 Professional

More than just the upgrade to Windows NT Workstation 4.0, Windows 2000 Professional is designed to replace Windows 95, Windows 98, and Windows NT Workstation 4.0 on all business desktops and laptops. Built on top of the proven Windows NT Workstation 4.0 code base, Windows 2000 adds major improvements in reliability, ease of use, Internet compatibility, and support for mobile computing.

Among other improvements, Windows 2000 Professional simplifies hardware installation by adding support for a wide variety of new Plug and Play hardware, including advanced networking and wireless products, USB devices, IEEE 1394 devices, and infrared devices.

Geek trivia: The nightly stress test performed on Windows 2000 during development is the equivalent of three months of run time on up to 1,500 computers.

2001–2005: Windows XP—Stable, usable, and fast


The Windows XP Home Edition desktop

On October 25, 2001, Windows XP is released with a redesigned look and feel that's centered on usability and a unified Help and Support services center. It’s available in 25 languages. From the mid-1970s until the release of Windows XP, about 1 billion PCs have been shipped worldwide.

For Microsoft, Windows XP will become one of its best-selling products in the coming years. It’s both fast and stable. Navigating the Start menu, taskbar, and Control Panel are more intuitive. Awareness of computer viruses and hackers increases, but fears are to a certain extent calmed by the online delivery of security updates. Consumers begin to understand warnings about suspicious attachments and viruses. There’s more emphasis on Help and Support.

·         Windows XP Tablet PC Edition (2002) realizes the vision of pen-based computing. Tablet PCs include a digital pen for handwriting recognition and you can use the mouse or keyboard, too.

Geek trivia: Windows XP is compiled from 45 million lines of code.

2006–2008: Windows Vista—Smart on security


The Windows Vista desktop

Windows Vista is released in 2006 with the strongest security system yet. User Account Control helps prevent potentially harmful software from making changes to your computer. In Windows Vista Ultimate, BitLocker Drive Encryption provides better data protection for your computer, as laptop sales and security needs increase. Windows Vista also features enhancements to Windows Media Player as more and more people come to see their PCs as central locations for digital media. Here you can watch television, view and send photographs, and edit videos.

Windows Vista UltimateWindows Vista Ultimate

Design plays a big role in Windows Vista, and features such as the taskbar and the borders around windows get a brand new look. Search gets new emphasis and helps people find files on their PCs faster. Windows Vista introduces new editions that each have a different mix of features. It's available in 35 languages. The redesigned Start button makes its first appearance in Windows Vista.

Geek trivia: More than 1.5 million devices are compatible with Windows Vista at launch.

2009: Windows 7


The Windows 7 desktop

Windows 7 was built for the wireless world that arose in the late 2000s. By the time it was released, laptops were outselling desktops, and it had become common to connect to public wireless hotspots in coffee shops and private networks in the home.

Windows 7 included new ways to work with windows—like Snap, Peek, and Shake—which both improved functionality and made the interface more fun to use. It also marked the debut of Windows Touch, which let touchscreen users browse the web, flip through photos, and open files and folders.

Geek trivia: Power users will notice that Windows 8 has made the detection and correction of file system errors both more transparent and less intrusive.

Geek trivia: Windows 7 was evaluated by 8 million beta testers worldwide before it was released.

2012: Windows 8


A PC running Windows 8

Windows 8 is Windows reimagined from the chipset to the user experience. It functions as both a tablet for entertainment and a full-featured PC for getting things done. It introduces a totally new interface that works smoothly for both touch and mouse and keyboard. Windows 8 also includes enhancements of the familiar Windows desktop, with a new taskbar and streamlined file management.

Windows 8 features a Start screen with tiles that connect to people, files, apps, and websites. Apps are front and center, with access to a new place to get apps—the Windows Store—built right in to the Start screen.

Along with Windows 8, Microsoft also launched Windows RT, which runs on some tablets and PCs. Windows RT is designed for sleek devices and long battery life, and exclusively runs apps from the Windows Store. It also comes with a built-in version of Office that's optimized for touchscreens.

AN ADVANCED PERSISTENT THREAT(APT)

An advanced persistent threat (APT) is a network attack in which an unauthorized person gains access to a network and stays there undetected for a long period of time. The intention of an APT attack is to steal data rather than to cause damage to the network or organization. APT attacks target organizations in sectors with high-value information, such as national defense, manufacturing and the financial industry.
In a simple attack, the intruder tries to get in and out as quickly as possible in order to avoid detection by the network's intrusion detection system (IDS). In an APT attack, however, the goal is not to get in and out but to achieve ongoing access. To maintain access without discovery, the intruder must continuously rewrite code and employ sophisticated evasion techniques. Some APTs are so complex that they require a full time administrator.
An APT attacker often uses spear fishing, a type of social engineering, to gain access to the network through legitimate means. Once access has been achieved, the attacker establishes a back door.
The next step is to gather valid user credentials (especially administrative ones) and move laterally across the network, installing more back doors. The back doors allow the attacker to install bogus utilities and create a "ghost infrastructure" for distributing malware that remains hidden in plain sight.
Although APT attacks are difficult to identify, the theft of data can never be completely invisible. Detecting anomalies in outbound data is perhaps the best way for an administrator to discover that his network has been the target of an APT attack.
