Mark Shuttleworth

Mark Richard Shuttleworth (born 18 September 1973) is a South African entrepreneur who was the second self-funded space tourist (after Dennis Tito). Shuttleworth founded Canonical Ltd.and as of 2010, provides leadership for the Ubuntu operating system. He has a net worth of £150 million ($225 million). He currently lives in the Isle of Man and holds dual citizenship ofSouth Africa and the United Kingdom.



Early life

Shuttleworth was born in WelkomFree StateSouth Africa as a son of a surgeon and a nursery school teacher.After attending school at Rondebosch Boys' High School[citation needed] andDiocesan College, Shuttleworth obtained a Business Science degree in Finance and Information Systems at the University of Cape Town. He lived in Smuts Hall, where he was involved in the installation of the first residential Internet connections at the university.

Work

Shuttleworth founded Thawte in 1995, which specialised in digital certificates and Internet security and then sold it to VeriSign in December 1999, earning R 3.5 billion (about US$ 575 million at the time).
In September 2000, Shuttleworth formed HBD Venture Capital, a business incubator and venture capital provider. In March 2004 he formed Canonical Ltd., for the promotion and commercial support of free software projects. In December 2009, Shuttleworth stepped down as the C.E.O. of Canonical, Ltd.

Involvement in Linux and FOSS

In the 1990s, Shuttleworth participated as one of the developers of the Debian operating system.
In 2001 he formed the Shuttleworth Foundation, a non-profit organization dedicated to social innovation which also funds educational, free, and open source software projects in South Africa, such as the Freedom Toaster.
In 2004 he returned to the free software world by funding the development of Ubuntu, a Linux distribution based on Debian, through his company Canonical Ltd.
Mark Shuttleworth

On 15 October 2006 it was announced that Mark Shuttleworth became the first patron of KDE, the highest level of sponsorship available. In 2005 he founded the Ubuntu Foundation and made an initial investment of 10 million dollars. In the Ubuntu project, Shuttleworth is often referred to with the tongue-in-cheek title Self-AppointedBenevolent Dictator for Life, abbreviated SABDFL. To come up with a list of names of people to hire for the project, Shuttleworth took six months of Debian mailing list archives with him while travelling to Antarctica aboard the icebreaker Kapitan Khlebnikov in early 2004. In September 2005, he purchased a 65% stake of Impi Linux.
On 17 December 2009 Mark announced that, effective March of 2010, he would step down as CEO of Canonical to focus energy on product design, partnership and customers. Jane Silber, COO at Canonical since 2004, will take on the job of CEO at Canonical. In September 2010, he received a honorary degree from the Open University for this work.


Spaceflight
While in space he had a radio conversation with Nelson Mandela and a 14 year old South African girl, Michelle Foster, who asked him to marry her. He politely dodged the question, stating that he was "very honoured at the question" before changing the subject. The terminally ill Miss Foster was provided the opportunity to have a conversation with Mark Shuttleworth and Nelson Mandela by the Reach for a Dream foundation.Shuttleworth gained worldwide fame on 25 April 2002 as the second self-funded spaceflight participant. Working with Space Adventures, he launched aboard the Russian Soyuz TM-34mission, paying approximately US$ 20 million for the voyage. Two days later, the Soyuz spacecraft arrived at the International Space Station, where he spent eight days participating in experiments related to AIDS and genome research. On 5 May 2002, he returned to Earth onSoyuz TM-33. In order to participate on the flight, Shuttleworth had to undergo one year of training and preparation, including seven months spent in Star City, Russia.

Transport

He has a private jet, a Bombardier Global Express, which is often referred to as Canonical One but is in fact owned through hisHBD Venture Capital company. The dragon depicted on the side of the plane is "Norman", the HBD Venture Capital mascot.

Ubuntu Studio

Ubuntu Studio is an officially recognized derivative of the Ubuntu Linux distribution, which is explicitly geared to general multimedia production. The original version, based on Ubuntu 7.04, was released on May 10, 2007.



Features


Real-time kernel

The real-time kernel, first included with Ubuntu Studio 8.04, was modified for intensive audio, video or graphics work. The 8.10 release lacks this real-time kernel. It has been reimplemented in the 9.04 release and stabilized with the release of 9.10. 10.04, in contrast, does not include the real-time kernel by default. As of version 10.10, the real-time kernel is no longer available in the repositories.
Typically, computers used as audio workstations rely on hardware monitoring which may provide low latency, but does not allow the live signal to be manipulated beyond available hardware effects. To manipulate a live signal, software processing of the signal is necessary, which most audio work stations can only achieve with latencies greater than several tens of milliseconds. Thus, a notable advantage of the Linux real-time kernel is being able to achieve software processing with latencies well below the human perception threshold of 5 to 10ms.
The scheduler allows applications to request immediate CPU time, which can drastically reduce audio latency[2]. In 9.10, the "Ubuntu Studio Controls" provided under System>Administration permit the user to "Enable Nice," allowing the use of wireless networking and proprietary graphics cards drivers while maintaining low audio latency free of XRUNs (audio drop-outs) in JACK. A more negative value entered for "Nice" reserves more CPU time for real-time audio processes.


Appearance and sound theme

Ubuntu Studio also includes custom artwork and a blue-on-black theme, as opposed to Ubuntu's default purple and orange. As with the main distribution of Ubuntu, if graphics card drivers are used, the advanced desktop effects can be enabled. More advanced Compiz effects are available in the Synaptic Package Manager (i.e., Ubuntu repositories). In Karmic 9.10, a fresh sound theme replaces the default Ubuntu theme, with a reverberating melody at startup, and an occasional knock or ping from a button or prompt.


Access to Ubuntu repositories

An important advantage of Ubuntu Studio over most other Linux distributions employing the real-time kernel is access to the same repositories available to the main Ubuntu distributions through the Update Manager, Synaptic Package Manager, as well as through the Add/Remove Applications prompt. This allows for much more frequent operating system updates, and access to a much wider range of software.


Installation

There is currently no live version available of Ubuntu Studio, and consequently, no graphical installer. In addition, the disk image is about 1.8 GB, too large to fit on a standard CD, and as a result the recommended installation medium for Ubuntu Studio is a DVD or USB flash drive. Ubuntu Studio can also be installed on a pre-existing Ubuntu installation by installing the "ubuntustudio-desktop" package from Advanced Packaging Tool.
In 9.10, the package "ubuntustudio-audio," shown during installation (and also available in the Synaptic Package Manager), cannot be installed without a working Internet connection.
A readily available internet connection is required after installation to maintain system components.
