Without industry and frugality, nothing will do, and with them everything.” Benjamin Franklin The cost of information technology (IT) as a percentage of overall operating and capital expenditures is growing as companies modernize their operations and as IT becomes an increasingly indispensable part of company resources.

Firstly with any software package before making decisions most people will look at what it would cost me as user to purchase it. With windows 8 you are looking at a retail price of R800 upwards, but of course as a student of Stellenbosch University, it can be purchased for a mere R180-00 from the Student IT Centre. However with Ubuntu, it’s completely free! Now let’s have a look at how they differ at first glance, Ubuntu brings their Unity look to the platform whereas Windows 8 brings there new metro look to theirs. Ubuntu is also a fairly light weight operating system compared to Windows 8 which takes up 16 to 20 GB of hard drive space compared to Ubuntu’s 4.5GB.

Cheriton School of Computer Science University of Waterloo [apokluda | mfbari | r5ahmed | rboutaba]@uwaterloo.ca 2American University of Beirut [email protected] University of Waterloo Technical Report: CS-2013-15∗ ∗This report is a modified version of an internal technical report produced for Orange Labs, the project's sponsor. The original technical report was submitted to Orange Labs in August 2013. Abstract During the main phase of this project we identified and provided solution for the major challenges related to peer-to-peer (P2P) web hosting. More specifically, our solutions for naming, availability, ranking, indexing and dynamic web-hosting have been provided in previous reports. In this report we present a more concrete view of the pWeb infrastructure and address the issues related to a real-life deployment of the system. First we provide an overview of the light-weight P2P communication protocol between pWeb clients for signaling and media streaming in Part I. In Part II we provide an architectural overview of pWeb system and show the mapping of the abstract components in pWeb architec- ture to real life devices and technologies. In order to make pWeb compatible with the existing Web technology we have developed a DNS gateway. In Part II Section 3, we provide the design and implementation of this DNS gateway. For efficient indexing and fast discovery of end-user devices and multimedia content, we have developed a cloud-based solution for crawling, indexing and searching.

The multidisciplinary ECE Senior Design Team #4 was tasked with creating a new, unique UAV capable of scanning disaster zones and identifying unique objects of interest. Careful research and planning has led to an innovative flight control architecture. The final product features a powerful onboard computer capable of live image processing for object detection, with distinct algorithms for color filtering and pedestrian tracking. A conversion algorithm was also implemented for converting the UAV’s latitude and longitude data, which is read from the flight control hardware, into USNG format. An IP network governs all communication between the ground station and the UAV. In the pursuit of increasing autonomy and implementing computer vision, a reliable and consistent object detection remains integral to accomplishing this task. By analyzing an image in search of HSV values that satisfy a predetermined range of color, any region of pixels that comply with the given range is highlighted using the color filtering algorithm.
  • Mobile Open Source Economic Analysis

    Mobile Open Source Economic Analysis

    Mobile Open Source Economic Analysis LiMo Foundation White Paper August 2009 ™ ™ White Paper 1 Executive Summary It is possible to use quantitative techniques to examine a number of the proposed economic benefits of open source software. The claimed benefits are a reduction in cost of acquisition, access to innovation and cost of ownership of software technology. The quantitative techniques we use to conduct our analysis are based on measuring source lines of code (SLOC) applied to publicly accessible open source project repositories. To aid our analysis, we have developed a command line tool to mine information on open source projects using the ohloh1 web service. Based on this analysis, Based on this analysis, there is a strong case for constructive engagement with there is a strong case for open source communities where the corresponding open source software constructive engagement components are used within a collaboratively developed, open mobile software with open source platform such as the LiMo Platform™. communities... There is additionally a case for mobile software platform providers to consider using certain strategic open source projects as the basis for development of new functionality on their roadmap. There is no proven case within this analysis for converting existing proprietary items already within a mobile software platform to open source. To conduct a cost-benefit analysis of that scenario would require examination of more factors than SLOC alone. 1http://www.ohloh.net ™ White Paper 1 1. Introduction The subject of open source is increasingly important in relation to mobile device platforms and in view of this, it is vital to understand the underlying economic factors driving the use of open source software in a mobile context.
