Ultumix GNU/Linux 0.0.1.7 32 Bit!
Welcome to Ultumix GNU/Linux 0.0.1.7 32 Bit! What is Ultumix GNU/Linux 0.0.1.7? Ultumix GNU/Linux 0.0.1.7 is a full replacement for Microsoft©s Windows and Macintosh©s Mac OS for any Intel based PC. Of course we recommend you check the system requirements first to make sure your computer meets our standards. The 64 bit version of Ultumix GNU/Linux 0.0.1.7 works faster than the 32 bit version on a 64 bit PC however the 32 bit version has support for Frets On Fire and a few other 32 bit applications that won©t run on 64 bit. We have worked hard to make sure that you can justify using 64 bit without sacrificing too much compatibility. I would say that Ultumix GNU/Linux 0.0.1.7 64 bit is compatible with 99.9% of all the GNU/Linux applications out there that will work with Ultumix GNU/Linux 0.0.1.7 32 bit. Ultumix GNU/Linux 0.0.1.7 is based on Ubuntu 8.04 but includes KDE 3.5 as the default interface and has the Mac4Lin Gnome interface for Mac users. What is Different Than Windows and Mac? You see with Microsoft©s Windows OS you have to defragment your computer, use an anti-virus, and run chkdsk or a check disk manually or automatically once every 3 months in order to maintain a normal Microsoft Windows environment. With Macintosh©s Mac OS you don©t have to worry about fragmentation but you do have to worry about some viruses and you still should do a check disk on your system every once in a while or whatever is equivalent to that in Microsoft©s Windows OS. -
A Framework for Real-Time Communications
Anton is a leading experts on Real Time Anton Venema Communications solutions, and the 1 Chief Technology Officer visionary lead architect behind IceLink, WebSync and LiveSwitch. iRTC Internet-Based Real Time Communications Introduction What’s the first thought that comes into your mind when you think about real-time communications? Is it a phone call you had a few minutes ago? A text message sent to your mobile? Maybe something more modern, like a tweet or video broadcast? All of these fall under the umbrella of what we like to call Internet-based real time communications, or iRTC for short. Real-time communications have been a part of our lives for a long time. From public telephone networks to radios all the way back to the telegraph, humanity has a history of seeking out new and better ways to use technology to improve communication. In the past decade, technology has arguably advanced more than the past century before it. Smartphones have stormed the market, mobile processors are advancing in line with Moore’s law, LTE rollouts are delivering unprecedented Internet speeds across the world, and WiFi hotspots are becoming ubiquitous. iRTC Includes Many Applications The availability of high-speed Internet services just about everywhere is causing a fundamental shift in the way people want to communicate and consume media. Cable networks are finding it more difficult to distinguish between their Internet and TV services, especially when companies like Netflix and HBO are able to publish their content directly to consumers over the Internet. Even live broadcasts, TV’s last stronghold, are being slowly replaced as platforms like YouTube allow content to be broadcast live to millions of users simultaneously over the Internet. -
Panoramas Shoot with the Camera Positioned Vertically As This Will Give the Photo Merging Software More Wriggle-Room in Merging the Images
P a n o r a m a s What is a Panorama? A panoramic photo covers a larger field of view than a “normal” photograph. In general if the aspect ratio is 2 to 1 or greater then it’s classified as a panoramic photo. This sample is about 3 times wider than tall, an aspect ratio of 3 to 1. What is a Panorama? A panorama is not limited to horizontal shots only. Vertical images are also an option. How is a Panorama Made? Panoramic photos are created by taking a series of overlapping photos and merging them together using software. Why Not Just Crop a Photo? • Making a panorama by cropping deletes a lot of data from the image. • That’s not a problem if you are just going to view it in a small format or at a low resolution. • However, if you want to print the image in a large format the loss of data will limit the size and quality that can be made. Get a Really Wide Angle Lens? • A wide-angle lens still may not be wide enough to capture the whole scene in a single shot. Sometime you just can’t get back far enough. • Photos taken with a wide-angle lens can exhibit undesirable lens distortion. • Lens cost, an auto focus 14mm f/2.8 lens can set you back $1,800 plus. What Lens to Use? • A standard lens works very well for taking panoramic photos. • You get minimal lens distortion, resulting in more realistic panoramic photos. • Choose a lens or focal length on a zoom lens of between 35mm and 80mm. -

The Perfect Desktop - Linux Mint 3.1 "Celena" FE
The Perfect Desktop - Linux Mint 3.1 "Celena" FE Version 1.0 Author: Oliver Meyer <o [dot] meyer [at] projektfarm [dot] de> Last edited 10/15/2007 This document describes how to set up a Linux Mint 3.1 "full edition" desktop. The result is a fast, secure and extendable system that provides all you need for daily work and entertainment. Linux Mint 3.1 builds upon Ubuntu Feisty and is compatible to its repositories - about 22.000 packages are available. This howto is a practical guide without any warranty - it doesn't cover the theoretical backgrounds. There are many ways to set up such a system - this is the way I chose. 1 Installation 1.1 Get Linux Mint "Celena" 3.1 FE The cd-image is available at http://linuxmint.com/download.html . 1.2 Live Start/restart your computer and insert the live-cd - be sure that your bios is configured to boot from your cd/dvd drive first. If there are no special reasons to do something else, select "Start Linux Mint" in the first window to boot the live-cd. The live-cd is starting up. A few moments later you'll see the desktop. 1.3 Start The Installation Double-click on the "Install"-button on the desktop. The install wizard appears. Choose your preferred language and proceed. Select the timezone nearest to your location and proceed. Choose your keyboard layout and proceed. Select how you want to partition the disk and proceed. If you chose the manual partition in the window before, you'll see this window. -

Das CD-Brennprogramm K3b

Ich habe mir mit man cdrecord zwar ein paarmal die Optionen von cdrecord angesehen, benutzt habe ich es aber auf diese Weise nie: das schien mir - als ehemaligem Windows-User - doch irgendwie zu unkomfortabel und vor allem zu fehleranfällig. Bei der Suche nach einem GUI-Programm, was zumindest ähnlich wie Nero unter Windows zu bedienen ist, stieß ich dann auf k3b, was ich im folgenden näher vorstellen möchte. Ich kann aufgrund des Funktionsumfangs nicht alles beschreiben, auch hängen besonders bei der Konfiguration zu viele Dinge vom individuellen Rechner und der bereits installierten Software ab, als dass ich auf alles eingehen kann. Da ich kein "Power-Burner" bin, sondern vor allem Daten-CDs für die Sicherung erstelle, bitte ich schon mal um Nachsicht, wenn die Pinguin-DJs vielleicht nicht ganz auf ihre Kosten kommen sollten..
