At—At, Batch—Execute Commands at a Later Time
at—at, batch—execute commands at a later time at [–csm] [–f script] [–qqueue] time [date] [+ increment] at –l [ job...] at –r job... batch at and batch read commands from standard input to be executed at a later time. at allows you to specify when the commands should be executed, while jobs queued with batch will execute when system load level permits. Executes commands read from stdin or a file at some later time. Unless redirected, the output is mailed to the user. Example A.1 1 at 6:30am Dec 12 < program 2 at noon tomorrow < program 3 at 1945 pm August 9 < program 4 at now + 3 hours < program 5 at 8:30am Jan 4 < program 6 at -r 83883555320.a EXPLANATION 1. At 6:30 in the morning on December 12th, start the job. 2. At noon tomorrow start the job. 3. At 7:45 in the evening on August 9th, start the job. 4. In three hours start the job. 5. At 8:30 in the morning of January 4th, start the job. 6. Removes previously scheduled job 83883555320.a. awk—pattern scanning and processing language awk [ –fprogram–file ] [ –Fc ] [ prog ] [ parameters ] [ filename...] awk scans each input filename for lines that match any of a set of patterns specified in prog. Example A.2 1 awk '{print $1, $2}' file 2 awk '/John/{print $3, $4}' file 3 awk -F: '{print $3}' /etc/passwd 4 date | awk '{print $6}' EXPLANATION 1.

On-Line Computing With a Hierarchy of Processors Abstract Time shared computer systems have been based upon the two techniques of multiprogramming and swapping. Multiprogramming is based on restricting each program to a portion of the total computer memory. Swapping requires considerable overhead time for loading and unloading programs. To alleviate the size restriction due to multiprogramming, segmentation is employed, resulting in fact in vastly increased swapping. A new system architecture is proposed for time shared computing that alleviates the high overhead or program size restriction. It utilizes a hierarchy of processors, where each processor is assigned tasks on the basis of four factors: interactive requirements, frequency of use, execution time, and program length. In order to study the hierarchical approach to system architecture, the Moore School Problem Solving Facility (MSPSF) was built and used. The study of the manner of operation and the reactions of the users clarified and defined the Hierarchy of Processors system architecture. The Moore School Problem Solving Facility was implemented on second generation equipment, the IBM 7040, and therefore it is not possible to adequately compare the efficiency with third generation computers operating in a swapping mode. -

Computer Technology History
Computer Technology History The affects of technology on our society. After completing this lesson, you will know: The history of computers from the 1940s up to the present. The future of computing. The many ways in which computers are used in modern life. How to make computers accessible to persons with disabilities. How computers are used in business and education. First Off…What are Computers? A Computer is an electronic device that receives data (input), processes data, stores data, and produces a result (output). Software is the instructions and/or programs that control the computer. Atanasoff-Berry Computer 1939 The first computing machine to use electricity, vacuum tubes, binary numbers and capacitors was created. The capacitors were in a rotating drum that held the electrical charge for the memory. History of Computing 1940s The first computers were built for breaking enemy codes in WWII The first all-electronic computer was developed during the 1940s. MARK series - 1944 Howard Aiken and Grace Hopper designed the MARK series of computers at Harvard University. The MARK series of computers began with the Mark I in 1944. Imagine a giant roomful of noisy, clicking metal parts, 55 feet long and 8 feet high. The 5-ton device contained almost 760,000 separate pieces. Used by the US Navy for gunnery and ballistic calculations, the Mark I was in operation until 1959. Vacuum Tube The vacuum tube was used to amplify voice and music. However, the tubes consumed power, created heat, burned out quickly, and required high maintenance. “Debugging” In the 1940s, computers were housed in buildings with no air conditioning. -
Relational Constraint Driven Test Case Synthesis for Web Applications
Relational Constraint Driven Test Case Synthesis for Web Applications Xiang Fu Hofstra University Hempstead, NY 11549 [email protected] This paper proposes a relational constraint driven technique that synthesizes test cases automatically for web applications. Using a static analysis, servlets can be modeled as relational transducers, which manipulate backend databases. We present a synthesis algorithm that generates a sequence of HTTP requests for simulating a user session. The algorithm relies on backward symbolic image computation for reaching a certain database state, given a code coverage objective. With a slight adaptation, the technique can be used for discovering workflow attacks on web applications. 1 Introduction Modern web applications usually rely on backend database systems for storing important system infor- mation or supporting business decisions. The complexity of database queries, however, often complicates the task of thoroughly testing a web application. To manually design test cases involves labor intensive initialization of database systems, even with the help of unit testing tools such as SQLUnit [25] and DBUnit [8]. It is desirable to automatically synthesize test cases for web applications. There has been a strong interest recently in testing database driven applications and database man- agement systems (see e.g., [12, 4, 20]). Many of them are query aware, i.e., given a SQL query, an initial database (DB) instance is generated to make that query satisfiable. The DB instance is fed to the target web application as input, so that a certain code coverage goal is achieved. The problem we are trying to tackle is one step further – it is a synthesis problem: given a certain database state (or a relational constraint), a call sequence of web servlets is synthesized to reach the given DB state. -
Data Definition Language
1 Structured Query Language SQL, or Structured Query Language is the most popular declarative language used to work with Relational Databases. Originally developed at IBM, it has been subsequently standard- ized by various standards bodies (ANSI, ISO), and extended by various corporations adding their own features (T-SQL, PL/SQL, etc.). There are two primary parts to SQL: The DDL and DML (& DCL). 2 DDL - Data Definition Language DDL is a standard subset of SQL that is used to define tables (database structure), and other metadata related things. The few basic commands include: CREATE DATABASE, CREATE TABLE, DROP TABLE, and ALTER TABLE. There are many other statements, but those are the ones most commonly used. 2.1 CREATE DATABASE Many database servers allow for the presence of many databases1. In order to create a database, a relatively standard command ‘CREATE DATABASE’ is used. The general format of the command is: CREATE DATABASE <database-name> ; The name can be pretty much anything; usually it shouldn’t have spaces (or those spaces have to be properly escaped). Some databases allow hyphens, and/or underscores in the name. The name is usually limited in size (some databases limit the name to 8 characters, others to 32—in other words, it depends on what database you use). 2.2 DROP DATABASE Just like there is a ‘create database’ there is also a ‘drop database’, which simply removes the database. Note that it doesn’t ask you for confirmation, and once you remove a database, it is gone forever2. DROP DATABASE <database-name> ; 2.3 CREATE TABLE Probably the most common DDL statement is ‘CREATE TABLE’. -
