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.

Top Ten Reasons to use Ubuntu

Top Ten Reasons to use Ubuntu: Now that I am officially “switched”, I will outline the reasons why Ubuntu rises to the top of other Linux variants available.
  1. Hardware Recognition: I would have to say that Ubuntu is by far the best Linux variant available today for hardware recognition. I have installed Dapper Drake (the latest Ubuntu release) on almost 10 different PC’s with completely different hardware configurations and I cannot remember any hardware that was not recognized. I have also installed Ubuntu in a few virtual environments without any problems.
  2. Synaptic Package Manager: This tool makes switching from a Windows environment a breeze. Windows users will feel right at home with this indispensable graphical interface for package management and software installation.
  3. Fast Release Cycle: Ubuntu is set on a six month release cycle so you have a new version out every six months that is usually a pretty big change with a lot of new features. Similar to the yearly OS X release. Upgrading to the new versions is also a snap as they come packaged in the software update tool.
  4. Easy Switch from Windows: I have been a Windows user ever since I started using a computer. Occasionally I would try a Linux variant to see what all the hype was about, but I never was able to take the plunge until Ubuntu. Ubuntu allowed me to switch over with ease and the amount of support on the Internet was huge for a Linux newbie like myself.
  5. Root Account Disabled by Default: This may not seem like a big deal but it is a huge deal when it comes to security. Ubuntu functions so that the user created during installation is part of the sudo users group and can do root user tasks once authenticated. This means that any Ubuntu computer effectively has a different root user name and since root is the most attacked account on a Linux box, the Ubuntu computer becomes very secure for not having this account enabled by default.
  6. Internet Support: The on-line support for Ubuntu is amazing. This distribution is rather new compared to other Linux variants, but the amount of documentation out there already is nothing to shake a stick at.UbuntuForums.org is a daily necessity for tips and tricks and general support. Also most Linux software comes with an Ubuntu version already. Simply amazing.
  7. Free: ‘Cash is King’. Since this operating system is completely free, it ups the ante against Microsoft and Apple big time. Who doesn’t like something for free?
  8. Wireless Card Configuration: The built in wireless configuration tool makes it a snap to connect to WiFi points across the land. I recently traveled with my Ubuntu laptop and had zero problems connecting to an available WiFi point during my trip. I wish I could say the same for the Windows world. I really think wireless in Ubuntu is as easy as the wireless in Apple OS X, it just works.
  9. Easy to Dual Boot: If you’ve got an extra partition you are in luck. Setting up a Linux/Windows dual boot is always a scary proposition, but with Ubuntu it is easy as pie. I have created between 5 and 10 dual boot machines and have not had one problem. (I always install Windows first) In fact my laptop is triple booted with Windows, Ubuntu, and Red Hat and Ubuntu manages the boot sequence via grub. I have even successfully re-sized a Windows partition to add Ubuntu as a dual boot, but make sure you have a backup first in case something goes wrong.
  10. Integrated Software Update Tool: This tool compares to Windows Update and runs in the background. Not only does it update system stuff but installed applications as well (as long as they are in the repositories). Everything from the kernel to the browser, this tool is a must have to keep your machine up to date.
  11. EasyUbuntu: (Bonus!!) EasyUbuntu is the best free tool for Ubuntu users. This program is a must have when you set up a new Ubuntu box. It installs everything from video drivers to flash browser plug-ins and so simple your grandma could use it.
  12. It Just Works: (Bonus #2!!) From thumb drives to hardware configuration changes, Ubuntu handles it with ease. No blue screens of death or crashing system errors. Congratulations to the team responsible for bringing us this great OS!

What is Ubuntu?

Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit.
  • Ubuntu will always be free of charge, and there is no extra fee for the “enterprise edition”, we make our very best work available to everyone on the same Free terms.
  • Ubuntu includes the very best in translations and accessibility infrastructure that the Free Software community has to offer, to make Ubuntu usable by as many people as possible.
  • Ubuntu is shipped in stable and regular release cycles; a new release will be shipped every six months. You can use the current stable release or the current development release. A release will be supported for 18 months.
  • Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on.
Ubuntu is suitable for both desktop and server use. The current Ubuntu release suPublish Postpports Intel x86 (IBM-compatible PC), AMD64 (Hammer) and PowerPC (Apple iBook and Powerbook, G4 and G5) architectures.
Ubuntu includes more than 1000 pieces of software, starting with the Linux kernel version 2.6 and Gnome 2.16, and covering every standard desktop application from word processing and spreadsheet applications to internet access applications, web server software, email software, programming languages and tools and of course several games.
