ARCH USER STAFF Daniel Griffiths (Ghost1227) ........... Editor ello, and thank you for picking up issue #1 of Arch User Magazine! While David Crouse (Crouse) .......... Contributor the vast majority of you probably know me (or have at least seen me H around the forums), I feel that I should take a moment to introduce myself. My name is Daniel Griffiths, and I am a 26-year-old independent contractor in Delaware, US. Throughout my life, I have wandered through various UNIX/Linux systems including (but not limited to) MINIX, RedHat, Mandrake, Slackware, Gentoo, Debian, and even two home made distributions based on Linux From Scratch. I finally found Arch in 2007 and instantly fell in love with its elegant simplicity. Some of our more attentive readers may note that Arch already has a monthly newsletter. With the existence of the aformentioned newsletter, what is the point of adding another news medium to the mix? Fear not, newsletter readers, I have no intention of letting Arch User Magazine take the place of the newsletter. In fact, Arch User Magazine and the newsletter are intended to fill two very different needs in the Arch community. While the newsletter gives you a glimpse into the lives of WHAT IS ARCH LINUX? the Developers and the status of the distribution itself, Arch User is designed to Arch Linux is a lightweight, flexible Linux® showcase the community itself. distribution that tries to Keep It Simple. As this is our first issue, I give you no assurances as to the continued release of Our strong community is diverse and Arch User Magazine. However, I do promise that as long as you, the community, helpful, and we pride ourselves on the continue to express interest, I will continue to write. range of skillsets and uses for Arch that stem from it.

  • Geany Tutorial
    How to use Geany Geany is essentially a text editor. To begin writing your program, you will need to create a new, blank file. Click on New. A new file called untitled will appear. You may start writing. As soon as you do, the option to save the file will be available. If the name of your file is in red, it means that it hasn’t been saved since the last change that is made. Click on the button called Save next to the New button. Save the file in a directory you had previously created before you launched Geany and name it main.cpp. All of the files you will write and submit to will be named specifically main.cpp. Once the .cpp has been specified, Geany will turn on its color coding feature for the C++ template. Next, we will set up our environment and then write a simple program that will print something to the screen Feel free to supply your own name in this small program Before we do anything with it, we will need to configure some options to make your life easier in this class The vertical line to the right marks the ! boundary of your code. You will need to respect this limit in that any line of code you write must not cross this line and therefore be properly, manually broken down to the next line.

  • 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.
