Each paradigm will support a different way of thinking and problem solving. Paradigms are supported by programming language features. Some programming languages support more than one paradigm. There are many different paradigms, not all mutually exclusive. Here are just a few different paradigms. Low-level programming paradigm The features of Low-level programming languages give us the ability to manipulate the contents of memory addresses and registers directly and exploit the architecture of a given processor.

  • The Machine That Builds Itself: How the Strengths of Lisp Family
    Khomtchouk et al. OPINION NOTE The Machine that Builds Itself: How the Strengths of Lisp Family Languages Facilitate Building Complex and Flexible Bioinformatic Models Bohdan B. Khomtchouk1*, Edmund Weitz2 and Claes Wahlestedt1 *Correspondence: [email protected] Abstract 1Center for Therapeutic Innovation and Department of We address the need for expanding the presence of the Lisp family of Psychiatry and Behavioral programming languages in bioinformatics and computational biology research. Sciences, University of Miami Languages of this family, like Common Lisp, Scheme, or Clojure, facilitate the Miller School of Medicine, 1120 NW 14th ST, Miami, FL, USA creation of powerful and flexible software models that are required for complex 33136 and rapidly evolving domains like biology. We will point out several important key Full list of author information is features that distinguish languages of the Lisp family from other programming available at the end of the article languages and we will explain how these features can aid researchers in becoming more productive and creating better code. We will also show how these features make these languages ideal tools for artificial intelligence and machine learning applications. We will specifically stress the advantages of domain-specific languages (DSL): languages which are specialized to a particular area and thus not only facilitate easier research problem formulation, but also aid in the establishment of standards and best programming practices as applied to the specific research field at hand. DSLs are particularly easy to build in Common Lisp, the most comprehensive Lisp dialect, which is commonly referred to as the “programmable programming language.” We are convinced that Lisp grants programmers unprecedented power to build increasingly sophisticated artificial intelligence systems that may ultimately transform machine learning and AI research in bioinformatics and computational biology.

  • Chapter 10 Introduction to Batch Files
    Instructor’s Manual Chapter 10 Lecture Notes Introduction to Batch Files Chapter 10 Introduction to Batch Files LEARNING OBJECTIVES 1. Compare and contrast batch and interactive processing. 2. Explain how batch files work. 3. Explain the purpose and function of the REM, ECHO, and PAUSE commands. 4. Explain how to stop or interrupt the batch file process. 5. Explain the function and use of replaceable parameters in batch files. 6. Explain the function of pipes, filters, and redirection in batch files. STUDENT OUTCOMES 1. Use Edit to write batch files. 2. Use COPY CON to write batch files. 3. Write and execute a simple batch file. 4. Write a batch file to load an application program. 5. Use the REM, PAUSE, and ECHO commands in batch files. 6. Terminate a batch file while it is executing. 7. Write batch files using replaceable parameters. 8. Write a batch file using pipes, filters, and redirection. CHAPTER SUMMARY 1. Batch processing means running a series of instructions without interruption. 2. Interactive processing allows the user to interface directly with the computer and update records immediately. 3. Batch files allow a user to put together a string of commands and execute them with one command. 4. Batch files must have the .BAT or .CMD file extension. 5. Windows looks first internally for a command, then for a .COM files extension, then for a .EXE file extension, and finally for a .BAT or .CMD file extension. 6. Edit is a full-screen text editor used to write batch files. 7. A word processor, if it has a means to save files in ASCII, can be used to write batch files.

Embedded software systems, especially those used in smart devices, have be- come an essential constituent of the technological infrastructure of modern societies. Such systems, in order to be trusted in society, must be proved to be trustworthy. Trustworthiness is a composite non-functional property that implies safety, timeliness, security, availability, and reliability.

  • Starting a Batch File Example
    LA Solutions ShellBatch.doc Starting a Batch File from MicroStation There have been a couple of questions in the MicroStation newsgroups along the lines of “How do I start an operating system batch file without leaving MicroStation?” One answer to the question is to use Visual Basic for Applications (VBA), which is part and parcel of MicroStation V8. VBA provides extensive functionality, which you can extend by referencing built-in Visual Basic (VB) methods, and even by calling the Win32 native application programming interface (API) directly. VB provides a Shell() method, which means ‘attempt to start whatever executable program I give you’. A batch file (having a .bat extension) is not an executable file. The way to ‘execute’a batch file is to give its path to the Windows built-in command executable cmd.exe. The way to persuade the operating system to do something with a batch file is to put these ideas together like this… Shell(“cmd.exe /k batchfile.bat”) Unfortunately, things aren’t always as simple as we would like, because Shell() can’t itself divine the location of the executable file. The VBA project ShellBatch.mvba takes care of these details, and all you have to know is how to start it. 1. Copy ShellBatch.mvba to one of the folders in your computer’s VBA search path (MS_VBASEARCHDIRECTORIES). C:\Program Files\Bentley\Workspace\Standards\VBA is a good choice 2. Open MicroStation’s key-in window from the Utilities menu 3. Start your batch file with the following key-in: you must know the full path to the file: vba run [ShellBatch].Module1.Main <batch file path> For example: vba run [ShellBatch]Module1.Main D:\temp\test.bat Copyright © LA Solutions 2003…2005 visit http://www.la-solutions.co.uk.

  • C++ Tutorial Part I : Procedural Programming
    C++ Tutorial Part I : Procedural Programming C. David Sherrill School of Chemistry and Biochemistry School of Computational Science and Engineering Georgia Institute of Technology Purpose To provide rapid training in elements of C++ syntax, C++ procedural programming, and C++ object- oriented programming for those with some basic prior programming experience To provide a handy programming reference for selected topics To provide numerous, actual C++ code examples for instruction and reference Why C++? “Intermediate”-level language: allows for fine (low- level) control over hardware, yet also allows certain complex tasks to be done with relatively little code (high-level) Good for scientific applications: produces efficient, compiled code, yet has features that help one develop and maintain a complicated, large code (e.g., namespaces, object-oriented design) Recommended reading These notes were developed during my reading of “Sams Teach Yourself C++ in One Hour a Day,” 7th Edition, by Siddhartha Rao (Sams, Indianapolis, 2012). I recommend the book, it’s readable and to the point. A good mastery of C++ will probably require working through a book like that one, and doing some examples; notes like these only serve as a basic introduction or a quick review A Note on C++11 This was originally supposed to be C++0x, with the “x” filled in according to the year the new C++ standard was finalized (e.g., C++09 for 2009). However, the standard took longer than expected, and was only formalized in 2011. So, C++11 is what was formerly referred to as C++0x. As of 2013, the new C++11 standards are not yet fully implemented in many compilers.
