AJAX Wake on LAN

AJAX Wake on LAN Michael Kopps Semester Project CS301: Web Programming Dr. Chow Purpose As an institution of higher education, the University of Colorado at Colorado Springs has a great number of computing needs placed upon it. One pressure is to increase the sustainability of the campus as a whole, and the waste of electrical energy is a major factor that affects the environmental footprint of the university. With a large amount of computers on campus, it is wise to

implement power management to place computers in a suspend or reduced power state when not in use. Another factor is the need to provide a consistent and reliable means of data storage and access for whatever sort of research and learning that takes place on the campus. This means that the computers must be constantly up to date with security patches and clean of malicious software that can decrease the performance and even leak a valuable piece of research. Performing this requirement requires the computers to be on afterhours, when most computers are not in use. These two seemingly contradictory requirements present a massive challenge to the Information Technology department on the UCCS campus. In an effort to meet this challenge, a technology called Wake on LAN (WOL) was developed to wake computers connected to a network so they can be administered, even after they have been turned off by the normal user. To make WOL easier to use and manage, a web based interface utilizing asynchronous JavaScript and XML (AJAX) was developed. This emerging technology has transformed the internet from a quite static place to a much more dynamic and rich environment. AJAX Overview The beginnings of what it...

Database Programming MySQL and Perl DBI Randy Julian Lilly Research Laboratories Program Clients dbms MySQL interface DBI PERL CLIENT 1 Perl DBI/DBD Interfaces DBI is the generic interface which relies on a database specific driver: DBD Must install the mysql DBD driver to use the DBI interface with MySQL PPM>install DBD::mysql DBI: An Object Oriented Module… Uses the Perl Object-Oriented syntax for calls and access to return values: my $dbh = DBI->connect ( $dsn, $user_name, $password, { RaiseError => 1,

PrintError => 0 } ); 2 Naming Conventions DBI Handle Variable Names Name Meaning $dbh A handle to a database object $sth A handle to a statement (query) object $fh A handle to an open file $h A generic handle - depends on context DBI Non-Handle Variable Names Name Meaning $rc Return code from true/false operations $rv Return code from “int” operations $rows Return code from ops than return row count @ary Array (list) returned from a query Some DBI member functions ->connect() connect to a database ->prepare() setup a query ->execute() perform a query that returns a result set ->do() perform a query that returns row count ->finish() complete a partial query ->disconnect() disconnect from the database 3 Simple Example: dump_atom.pl

Introduction to Java Programming By Y. Daniel Liang

This supplement covers the following topics: • Starting and Stopping MySQL Server • Connecting to MySQL • Creating User Accounts • Using MySQL • MySQL Administration • Accessing MySQL using Java NOTE: Please use MySQL 4.1 or high with this tutorial. 0 Introduction MySQL is a popular database with more than 4 million users. It is one of the fastest relational databases in the market. Many

companies are using it to support their websites, data warehouses, and business applications. MySQL was developed by a Swedish company named MySQL AB. The product is distributed under GNU General Public License (GPL). It can support multiple users concurrently on the network. Students can connect to a MySQL database server standalone on their own computer or from the network. You can download it free from http://dev.mysql.com/downloads/mysql/4.1.html. MySQL runs on Windows, Linux and Solaris. This tutorial demonstrates using MySQL from the Windows operating system. 1 Starting and Stopping MySQL Server If your database server is not started, you can start it by typing “net start mysql” from the MySQL bin directory as shown in Figure 1.1. You can stop it by typing the command net stop mysql. Start MySQL Stop MySQL Figure 1.1 © Copyright Y. Daniel Liang, 2005 8 You need to start MySQL only once after the installation. NOTE Your system may be set up to start MySQL automatically. In this case, you don’t have to restart it. NOTE By default, MySQL 4.1 is installed under c:Program FilesMySQL directory. If it is installed elsewhere on your system, please use an...

Introduction to Database Programming using PHP and MySQL

Introduction to Database Programming using PHP and MySQL Revision 1.1 June 14, 2010 by Aloysius Indrayanto (C) 2010 AnemoneSoft.com This document is multi-licensed under the Creative Commons Attribution Share-Alike (CC-BY-SA) license version 3.0 and the GNU Free Documentation License (GNU FDL) version 1.3 or later. Introduction to Database Programming using PHP and MySQL Page 1 of 12 1. Introduction LAMP (an acronym for Linux, Apache, MySQL, and PHP) is basically the most popular solution stack to deliver a general-purpose web

and application server. A solution stack is a full set of software components bundled together to provide a specific solution. Basically, the exact combination of software included in LAMP can be modified, depending on the need of the developer. For example, PHP can be replaced with Python, Perl, or other scripting language. In MS Windows, the package is called WAMP. In Mac OS, it is called MAMP. In Solaris, it is called SAMP. In OpenBSD it is called OpAMP, etc. PHP: Hypertext Preprocessor was invented by Rasmus Lerdorf in 1995. PHP is both a general-purpose programming language and a scripting language. PHP can be used to develop general-purpose applications (with and without graphical interface) as well as dynamic web pages or web applications. PHP is an interpreted language. Currently, PHP is maintained by The PHP Group. PHP is free and open source. MySQL Community Server is a free and open source RDBMS (Relational Database Management System) that runs as a server to provide a multi-user database system. The original MySQL was developed by Michael Widenius. Currently, MySQL is owned and sponsored by Sun Microsystems, a subsidiary of Oracle Corporation. MySQL has been used in large-scale products, such as Wikipedia, Google,...

MySQL Tutorial - University of Ibadan

This tutorial is inspired by the examples of this book : MySQL™ The definitive guide to using, programming, and administering MySQL 4.1 and 5.0 Third Edition By Paul DuBois – SAMS March 2005 Design & Conception: P.K helped by A.D, L.W & S.S. A MySQL Tutorial Basic Database Terminology Many relational database concepts are really quite simple. In fact, much of the appeal of relational databases stems from the simplicity of their foundational concepts. Structural Terminology Within the database world,

MySQL is classified as a relational database management system (RDBMS). That phrase breaks down as follows: • The database (the "DB" in RDBMS) is the repository for the information you want to store, structured in a simple, regular fashion: o The collection of data in a database is organized into tables. o Each table is organized into rows and columns. o Each row in a table is a record. o Records can contain several pieces of information; each column in a table corresponds to one of those pieces. • The management system (the "MS") is the software that lets you use your data by allowing you to insert, retrieve, modify, or delete records. • The word "relational" (the "R") indicates a particular kind of DBMS, one that is very good at relating (that is, matching up) information stored in one table to information stored in another by looking for elements common to each of them. The power of a relational DBMS lies in its capability to pull data from those tables conveniently and to join information from related tables to produce answers to questions that can't be answered from individual tables alone. Here's an example that shows how a relational...
