Resurrect Your Old PC
Resurrect your old PCs Resurrect your old PC Nostalgic for your old beige boxes? Don’t let them gather dust! Proprietary OSes force users to upgrade hardware much sooner than necessary: Neil Bothwick highlights some great ways to make your pensioned-off PCs earn their keep. ardware performance is constantly improving, and it is only natural to want the best, so we upgrade our H system from time to time and leave the old ones behind, considering them obsolete. But you don’t usually need the latest and greatest, it was only a few years ago that people were running perfectly usable systems on 500MHz CPUs and drooling over the prospect that a 1GHz CPU might actually be available quite soon. I can imagine someone writing a similar article, ten years from now, about what to do with that slow, old 4GHz eight-core system that is now gathering dust. That’s what we aim to do here, show you how you can put that old hardware to good use instead of consigning it to the scrapheap. So what are we talking about when we say older computers? The sort of spec that was popular around the turn of the century. OK, while that may be true, it does make it seem like we are talking about really old hardware. A typical entry-level machine from six or seven years ago would have had something like an 800MHz processor, Pentium 3 or similar, 128MB of RAM and a 20- 30GB hard disk. The test rig used for testing most of the software we will discuss is actually slightly lower spec, it has a 700MHz Celeron processor, because that’s what I found in the pile of computer gear I never throw away in my loft, right next to my faithful old – but non-functioning – Amiga 4000. -
Ubuntu Kung Fu
Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users.

106 INKSCAPE – FREE VECTOR GRAPHICS EDITOR Grabareva A
INKSCAPE – FREE VECTOR GRAPHICS EDITOR Grabareva A. Supervisor: Voevodina M. E-mail: [email protected], [email protected] Kharkiv, О.М. Beketov National University of Urban Economy in Kharkiv Inkscape is a cross-platform, powerful enough and in many ways competitive free vector graphics editor with open source code, and in which the SVG format is used as the main standard for work. It is convenient for creating both artistic and technical illustrations. Inkscape is an analogue of such graphic editors as Corel Draw, Adobe Illustrator, Xara X and Freehand. Intended use: - illustrations for office circulars, presentations, creation of logos, business cards, posters; - technical illustrations (diagrams, graphics, etc.); - vector graphics for high-quality printing (with preliminary import of SVG into Scribus); - web graphics – from banners to site layouts, icons for applications and website buttons, - graphics for games. Main characteristics of Inkscape: - the program is free and distributed under the GNU General Public License; - cross-platform; - the program supports the following document formats: import – almost all popular and frequently used formats: SVG, JPEG, GIF, BMP, EPS, PDF, PNG, ICO, and many additional ones, such as SVGZ, EMF, PostScript, AI, Dia, Sketch, TIFF, XPM, WMF, WPG, GGR, ANI, CUR, PCX, PNM, RAS, TGA, WBMP, XBM, XPM; export – the main formats are PNG and SVG and many additional EPS, PostScript, PDF, Dia, AI, Sketch, POV-Ray, LaTeX, OpenDocument Draw, GPL, EMF, POV, DXF; - there is support for layers; - -

Mobile Phones and Cloud Computing
Mobile phones and cloud computing A quantitative research paper on mobile phone application offloading by cloud computing utilization Oskar Hamrén Department of informatics Human Computer Interaction Master’s programme Master thesis 2-year level, 30 credits SPM 2012.07 Abstract The development of the mobile phone has been rapid. From being a device mainly used for phone calls and writing text messages the mobile phone of today, or commonly referred to as the smartphone, has become a multi-purpose device. Because of its size and thermal constraints there are certain limitations in areas of battery life and computational capabilities. Some say that cloud computing is just another buzzword, a way to sell already existing technology. Others claim that it has the potential to transform the whole IT-industry. This thesis is covering the intersection of these two fields by investigating if it is possible to increase the speed of mobile phones by offloading computational heavy mobile phone application functions by using cloud computing. A mobile phone application was developed that conducts three computational heavy tests. The tests were run twice, by not using cloud computing offloading and by using it. The time taken to carry out the tests were saved and later compared to see if it is faster to use cloud computing in comparison to not use it. The results showed that it is not beneficial to use cloud computing to carry out these types of tasks; it is faster to use the mobile phone. 1 Table of Contents Abstract ..................................................................................................................................... 1 Table of Contents ..................................................................................................................... 2 1.

Schon Mal Dran Gedacht,Linux Auszuprobieren? Von G. Schmidt
Schon mal dran gedacht, Linux auszuprobieren? Eine Einführung in das Betriebssystem Linux und seine Distributionen von Günther Schmidt-Falck Das Magazin AUSWEGE wird nun schon seit 2010 mit Hilfe des Computer-Betriebs- system Linux erstellt: Texte layouten, Grafiken und Fotos bearbeiten, Webseiten ge- stalten, Audio schneiden - alles mit freier, unabhängiger Software einer weltweiten Entwicklergemeinde. Aufgrund der guten eigenen Erfahrungen möchte der folgende Aufsatz ins Betriebssystem Linux einführen - mit einem Schwerpunkt auf der Distri- bution LinuxMint. Was ist Linux? „... ein hochstabiles, besonders schnelles und vor allem funktionsfähiges Betriebssystem, das dem Unix-System ähnelt, … . Eine Gemeinschaft Tausender programmierte es und verteilt es nun unter der GNU General Public Li- cense. Somit ist es frei zugänglich für jeden und kos- tenlos! Mehrere Millionen Leute, viele Organisatio- nen und besonders Firmen nutzen es weltweit. Die meisten nutzen es aus folgenden Gründen: • besonders schnell, stabil und leistungs- stark • gratis Support aus vielen Internet- Newsgruppen Tux, der Pinguin, ist das Linux-Maskottchen • übersichtliche Mailing-Listen • massenweise www-Seiten • direkter Mailkontakt mit dem Programmierer sind möglich • Bildung von Gruppen • kommerzieller Support“1 Linux ist heute weit verbreitet im Serverbereich: „Im Oktober 2012 wurden mindes- tens 32% aller Webseiten auf einem Linux-Server gehostet. Da nicht alle Linux-Ser- ver sich auch als solche zu erkennen geben, könnte der tatsächliche Anteil um bis zu 24% höher liegen. Damit wäre ein tatsächlicher Marktanteil von bis zu 55% nicht 1 http://www.linuxnetworx.com/linux-richtig-nutzen magazin-auswege.de – 2.11.2015 Schon mal dran gedacht, Linux auszuprobieren? 1 auszuschliessen. (…) Linux gilt innerhalb von Netzwerken als ausgesprochen sicher und an die jeweiligen Gegebenheiten anpassbar. -
