  1. CS145 Lecture 24 What’s next?

  2. What’s next? • What questions does Computer Science study? • Where is programming and Computer Science headed? • With special emphasis on software

  3. Basic Questions Programming Languages System Software Network Software Middleware Information Systems Scientific Computing Embedded and Real-Time Systems Graphics Artificial Intelligence Software Engineering What questions do we study

  4. Basic Questions • Data structures for storing and representing different kinds of data • Some kinds of structures • Maps (map one type of object to another) • Trees, Graphs • Sets • Analysis of Algorithms • Time and space efficiency of algorithms and data structures • Computer Architectures • How to make computers work better with various kinds of software • Better = Faster, Cheaper, Less Power Consumption, etc.

  5. Programming Languages • Imperative Languages • Ada, C, C++, Java, C#, … • Scripting Languages • Perl, Python, Ruby, JavaScript, … • OO Languages • C++, Java, C#, Python, … • LISP, Scheme • Functional • Haskell, CAML, …

  6. System Software • System Software: Software that supports other kinds of software • As opposed to application software: Software that faces the user • Some kinds of system software: • Operating systems • Including File Systems • Compilers and Virtual Machines for Programming Languages • Database Management Systems

  7. Network Software • Supports communication between systems and applications • Definition and Implementation of communication protocols • Interesting protocols • TCP/IP • HTTP (as opposed to HTML) • FTP • SSL

  8. Middleware • Software that sits between systems and applications • Typically systems (i.e. support) type software with more of an application focus • Some examples • Software for integrating different applications • Model Driven Architecture • Build your integration software by drawing the right kinds of diagrams

  9. Information Systems • Usually systems that support the operation of a business • More generally: Systems that store and manipulate business kinds of information • Some interesting areas: • Data Base (the organization of data, not the underlying software) • Business applications • ERP, CRS, … • Business rules • Just describe the rules and the necessary software is automatically generated

  10. Scientific Computing • Large numeric computations for science and engineering applications • Issues • Efficient algorithms for large computations • Efficient coordination of large computing resources • Some examples • Predict the weather or climate • Wind tunnel • Simulate nuclear weapons • Protein folding • Driver for much of the work on Clustered Systems

  11. Embedded and Real-Time Systems • Control operation of machines, equipment, etc. • Some issues • Operating systems supporting real-time (deadline) processing • Examples • Fly an airplane • Drive a car • Run a factory • Record a television program • Run the graphics card in your computer

  12. Graphics • Generate realistic graphics (pictures, video) from digital descriptions • Issues • Understanding how light interacts with physical objects • Efficient algorithms • Examples • Shrek, Gollum, Polar Express • Cleaning up old movies

  13. Artificial Intelligence • Software and systems that behaves as if they were intelligent • This is a large area with many sub areas: • Rule based systems • Neural Network • Natural language processing • Evolutionary algorithms • Machine Learning • Robotics • Game playing • Proving Software Correct • And more …

  14. Software Engineering • How to we go about building software? • Areas of interest • Requirements, Requirements Management • Architecture and Design • Testing • Software Methodology and Process • Diagramming Software (e.g. UML) • Managing Building Software • Costing and Scheduling of Software Development

  15. Where are Computers headed? • How good is your crystal ball? • Near-term growth in hardware capability is predictable • Right now no “killer aps” on the horizon

  16. Where are Computers headed?(My predictions) • Hardware • More parallelism in hardware (Multi-core systems) • Address heat/power consumption limits • Programming languages and systems • Try to make software developers more efficient • Have the software work harder to make developers job easier • Artificial Intelligence • More “intelligent” systems • Example of current work: Spam filters • Near-term focus: Robotics

  17. My predictions (continued) • Business applications • Standard “easily tailorable” applications • All areas • Make better use of increasing processing power and storage capacity • Software Engineering • “Software is always late and over budget” • Can we fix this?
