    ANNUAL REPORT 2008 Photo: Johan Schiff, CC-BY-SA-3.0 Photo: Fluff, CC-BY-SA-3.0 Photo: David Castor, Public domain Introduction Wikipedia, the free encyclopedia, is one of the world's ten most visited websites. The site is run by the Wikimedia Foundation, a non-profit foundation, which also operates several other free sites. Wikimedia Sverige is a local chapter of Wikimedia Foundation. The objective of the Wikimedia Sverige, a non-profit organization, is to make knowledge freely available to all people, especially by supporting the Wikimedia Foundation projects. Wikimedia Sverige was founded on October 20, 2007 so 2008 is the first complete year of operation of the association. During the year, the number of members doubled and the assets have increased by a factor of twenty. The board has during the year participated in four major events, held 12 lectures for different groups, participated in 21 local meetups and have had 19 Board meetings and an annual meeting. During the year we have also developed marketing materials, created a book on birds from material from Wikipedia and Wikimedia Commons, and provided support for Lennart Guldbrandssons popular book "This is how Wikipedia works". Internationally, the board participated in several events and developed personal contacts with other local chapters of the Wikimedia Foundation. In a short time we have been recognized as an active and effective organization. We feel a very positive feedback from various groups in the Swedish society and can with pleasure notice that Wikipedia has become increasingly more reliable and accepted for use in schools and by media.

In addition it'll play audible audiobooks plus MPEG4 videos and JPEG pictures. There's even a game feature for playing the included flash titles. According to iriver, you can also switch the clix between a MTP mode for easy synching with Windows Vista and XP (Service pack 1 or later) PCs and a UMS mode to drag and drop files over from older windows machines. Expect to find the device on sale now at iriver's online store. Copyright 2007 by Ziff Davis Media, Distributed by United Press International On Wednesday iriver followed up its interestingly designed clix MP3 player with its second- generation audio device, with a novel LCD screen for extended battery life. On Wednesday, iriver followed up its interestingly designed clix MP3 player with a new device. Termed the "second generation iriver clix," this latest portable digital audio product is also a small flash-memory based personal music player, just like its predecessor, and sports the same 4-way rocking screen for use as a main interface. Available in storage flavors of 2 Gbytes, 4 GB, and 8 GB – priced at $149.99, 199.99, and $249.99 respectively – the new clix boasts a sizeable 2.2-inch QVGA AMOLED (Active Matrix Organically Light Emitting Diode) screen. This display is designed to be more energy efficient than the ubiquitous LCDs found on competing players. As a result, iriver claims the clix to have a rated battery life of a lengthy 24 hours for music playback and 5 hours screening video.

  • Hedy Lamarr Achievement Award for “Emerging Leaders in Entertainment Technology”
    HEDY LAMARR ACHIEVEMENT AWARD FOR “EMERGING LEADERS IN ENTERTAINMENT TECHNOLOGY” PRESENTED BY: DEG: THE DIGITAL ENTERTAINMENT GROUP THE HEDY LAMARR ACADEMIC AWARD SCHOLARSHIP OVERVIEW DEG: The Digital Entertainment Group is pleased to announce the annual "Hedy Lamarr Achievement Award for Emerging Leaders in Entertainment Technology," which recognizes female college students in their junior year whose studies in the fields of entertainment and technology have shown exceptional promise. The $10,000 Award will be presented in November 2018, to coincide with the 104th anniversary of Hedy Lamarr's birth. Austrian-American actress Hedy Lamarr was a Hollywood legend who is best known for her roles in a number of film classics including, Samson and Delilah, The Strange Woman, and Tortilla Flat. She was also a lifelong inventor whose innovative work included pioneering "frequency hopping" which became the foundation for spread spectrum technology. Conceived by Lamarr and composer George Antheil for radio guidance systems and patented in 1942, this highly secure technology resists interference and dropout, and is utilized today for a variety of cellular, WiFi and Bluetooth applications. To honor Ms. Lamarr, the scholarship seeks to encourage and enable highly motivated students to pursue opportunities available to them in entertainment technology, be those pursuits academic or professional. The award winner will receive $10,000 as they enter their senior year of undergraduate study. While there are no specific restrictions on the use of this monetary award, we hope and expect that the funds will be used to further the winner’s study or efforts in their recognized area of excellence. In 2017, the DEG awarded a total of $35,000 to three young women: One a Performing Arts Technology major at the University of Michigan, one a in Media Arts and Practice major at the University of Southern California, and one a in Studio Art major with a minor in Arts and Technology at Smith College.
