Practice-It!, a web-based Java practice problem tool for computer science students How to build your own Linux distro Since Manchester University's Owen Le Blanc released MCC Interim Linux (generally agreed to have been the first Linux distribution), way back in 1992, there have been hundreds of ways to get the world's favourite free software operating system on to a computer. The diversity of alternatives reflects the diversity in the development community, with distros split along technical, functional, linguistic and even ideological lines. There have been large distros, tiny ones, bleeding edge and rock-solid stable distros. Easy for the newbie to install, or downright impenetrable to the uninitiated. Created exclusively with free software as a badge of pride, or so proprietary in attitude that not even the toolchain was fully GNU (hello Red Flag Server 4.1, built with the Intel compiler in 2004). So with all the variety that's already out there, why would anyone want to create their own distro? What this amounts to is that it doesn't take much to warrant a new distro. Which base? The simple choices
Indoor Autonomous Positioning SCP technology makes it possible to provide reliable, consistent, and accurate indoor positioning without the support of network infrastructure and services. By exploiting freely available signals including GPS, cellular, digital television, and wireless LAN (e.g. WiFi), SCP based Doppler Aided Inertial Navigation (DAIN) determines location through a sensor fusion approach. Combining inertial, magnetic, and gravity data with the SCP RF observables, DAIN provides continuous position, velocity, and direction information. A fundamental breakthrough in indoor positioning, SCP DAIN is ideal for emerging location enabled applications hosted on smart phone devices. DAIN is an ideal enabler for both consumer and commercial applications.
Indoor Navigation with SVG SVG, positioning technologies, mobility, guiding system Christian SchmittResearcherFraunhofer FIT Schloss Birlinghoven Sankt-Augustin Germany christian.schmitt@fit.fraunhofer.de Oliver KaufmannFraunhofer FITSchloss Birlinghoven Sankt-Augustin Germany oliver.kaufmann@fit.fraunhofer.de This paper describes a mobile guide providing office building visitors with indoor navigation aid. 1. 1. FIT has a long history in developing mobile guides for museums, fairs, symposiums. Our mobile guide was developed with the aim to be used for demo purposes by visitors to our institute, for demonstrating our expertise in mobile computing, positioning technologies and human-computer interface. Present information about our research department (employees, projects)Let the user experience indoor navigation on our floor Presenting information can be easily achieved by integrating functionalities from the Pocket Internet Explorer in the application and having the content available as HTML pages. 2. 3. 4.
Introduction to Object Oriented Programming Concepts (OOP) and More Recommended framework: Table of contents 1. Introduction I have noticed an increase in the number of articles published in the Architecture category in CodeProject during the last few months. One day I read an article that said that the richest two percent own half the world's wealth. Coming back to the initial point, I noticed that there is a knowledge gap, increasing every day, between architects who know how to architect a system properly and others who do not. 2. This article began after reading and hearing questions new developers have on the basics of software architecture. As I see it, newcomers will always struggle to understand the precise definition of a new concept, because it is always a new and hence unfamiliar idea. 3. This article is an effort to provide an accurate information pool for new developers on the basics of software architecture, focusing on Object Oriented Programming (OOP). 4. 4.1. 4.2. 4.3. OOP is a design philosophy. 1.
