Adding Support for Jamendo and Magnatune to Rhythmbox on Linux
Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog Adding support for Jamendo and Magnatune to Rhythmbox on Linux Author : admin I'm using rhythmbox to play music on my Debian Linux. Rhythmbox is a good substitute for both audacious and xmms. XMMS is already very obsolete and it often crashes because of some of it's plugins. On the other hand audacious is sometimes having problems on my notebook working with it's alsa plugin or pulseaudio especially if I play something in youtube. With audacious my songs sometimes got stucked for some weird reason. With rhythmbox I have never experienced this kind of issues. Considering the fact that I'm a GNOME user rhythmbox is even more attractive for me. During about 2 years ago I've heard about the Jamendo - community of free, legal and unlimited music published under the Creative Commons licenses. Just about 10 months ago I've also discovered magnatune which is also a radio which allows free listening online of it's whole online catalogue. That's why it was really interesting for me to have this two nice music streaming services directly into my rhythmbox. I was very happy to discover that already a plugin that embeds the Jamendo and Magnatune Support to the Rhytmbox program. To enable Rhythmbox to support Magnatune and Jamendo type in your root terminal: debian:~# apt-get install gmpc-plugins gmpc-plugins-dbg debian:~# apt-get rhythmbox-plugins It's very likely that the rhythmbox-plugins might be already installed on your Linux, anyways I put the command above just in case if for some reason it's not installed. -
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. -

Is -Open Source- a Keyword for a Successful Gis Development ?
IS -OPEN SOURCE- A KEYWORD FOR A SUCCESSFUL GIS DEVELOPMENT ? Umit Isikdag(MSc,BSc) University of Salford,UK School of Construction & Property Management [email protected] 1.What is a Geographical Information System ? A GIS can be defined as an information system capable of assembling, storing, manipulating, and displaying geographically referenced information. GIS is also regarded as “a computer system for capturing, storing, checking, integrating, manipulating, analysing and displaying data related to positions on the Earth's surface. Typically, a Geographical Information System (or Spatial Information System) is used for handling maps of one kind or another. These might be represented as several different layers where each layer holds data about a particular kind of feature. Each feature is linked to a position on the graphical image of a map.”12 Figure 1.1-Typical Components of a GIS 1.1 The basic functions of a GIS The basic functions of a GIS are defined as13 capturing the data,integrating the data,projection and registration,sturucturing and modelling the data.The USGS web site(http://www.usgs.gov) defines these functions in detail as: Data Capture:Maps can be digitized, or hand-traced with at computer mouse, to collect the coordinates of features. Data capture - putting the information into the system - is the time-consuming component of GIS work. Identities of the objects on the map must be specified, as well as their spatial relationships. Editing of information that is automatically captured can also be difficult. Electronic scanners record blemishes on a map just as faithfully as they record the map features. -

EXPERIENCE WITH A LIVECD IN AN EDUCATION PROCESS Experience with a LiveCD in an education process Jan R˚uˇziˇcka, FrantiˇsekKl´ımek Institute of Geoinformatics Faculty of Mining and Geology, VSB-TUO E-mail: [email protected] Key words: LiveCD, GIS´akLiveCD, Distance Learning, E-learning Abstract The paper describes how can be LiveCD (Bootable CD) used for geoinformatics distance learn- ing. We have prepared one LiveCD with basic software for learning geoinformatics and we have some feedback from users and teachers. The paper should evaluate this feedback. LiveCD is a CD-ROM, that can be used as a bootable device. After booting from the CD, the user can access all resources compiled to the CD. There are operating system (usually based on GNU/Linux) and (user, desktop) software installed and configured to be used directly after boot. Our CD named GIS´akLiveCD contains basic GIS software such as UMN MapServer, GRASS, Quantum GIS, Thuban, JUMP, GPS Drive, Blender and we work on other soft- ware packages such as MapLab for UMN MapServer, PostGIS, GeoNetwork Open Source, CatMDEdit, gvSIG, uDIG. GIS´akLiveCD contains set of spatial data from the Czech Re- public. Main part of the CD are tutorials for GIS software. CD is open for other e-learning materials. Now we have about 20 students using our LiveCD and few other users that are not curently our students. The paper should show Pros & Cons of the LiveCD usage for a distance learning. LiveCD Live CD is bootable CD-ROM with operating system and installed and configured programs. It is ready to use as full installed system directly after boot from CD-ROM drive. -
Development of Cloud-Based Media Player Using Microsoft Azure Services
eISSN:2600-7920 INTI JOURNAL Vol.1, 2018 (24) Development of Cloud-Based Media Player using Microsoft Azure Services Chong Fong Kim1, Chan Yong Kai 2 and Deshinta Arrova Dewi3 1,2,3 Faculty of Information Technology and Science, INTI International University, Nilai, Negeri Sembilan, Malaysia. Corresponding Author: [email protected] Abstract Playing songs offline consumes internal storage capacity of a device. Besides, playing songs, most of the time is an individual acting as a hobby and many song listeners do not have a common platform to share their hobby with others. By putting it on the cloud, the internal storage capacity can be reduced and the chance to share the common hobby with others is available. This paper aims to present the development of a Cloud-Based Media Player (CBMP) to ease the users in managing their song files and sharing with others. The CBMP utilizes a website as the main controller and connects to the Microsoft Azure Services to host the music database. Two separate sections are created for the user to upload and download their songs as private and share sections. Accordingly, users can choose the favored section they want to access. Not only features to upload and download songs are provided, but the CMBP also provides a search function that enables users to search songs in both different to make a search process faster. Due to latency in the cloud services, the suggested song format for CMBP is.MP3 files. The .MP3 files promote better compression rate than .MP4. Besides, .MP4 has higher latency that makes users waiting longer for processing the songs. -

"Graph" Program
Physics 305 Introduction to Computational Physics Fall 2010 The graph program Unfortunately, graphics programs are not as universal as we would like. These notes discuss one simple graphics program, unimaginatively called “graph”. While it is not a part of the standard Linux setup, it is universally available (and free) from the GNU software project. In fact, it is written and maintained by Robert Maier in the UA Math department. More importantly for you, it is already installed on faraday. Before you try out “graph”, make a couple of data files to practice on. These should be just two columns of number, where each line is an (x, y) pair. For example, file “data1” might look like: 0.0 0.123 0.5 0.2245 0.7 0.3145 1.1 0.224 Note that the x values don’t have to be evenly spaced. graph can make several kinds of output. The two that are important to us are X-windows output, which makes plots appear on the screen in front of you, and PostScript output, which you can email as part of your homework assignment. (You can, and should, also view the PostScript on your screen by using the “gv” (short for “ghostview”) command. Now try it out. Suppose “data1” is the name of one our your practice data files. Type graph -T X data1 WATCH OUT. Upper and lower case matters. Spacing and punctuation matter. “-T” and “X” must be upper case, and there must be a space between them. This should produce a graph of your data file on your screen.
