                              The World Changes

Compared to my university’s computer when I was a
  graduate student, my laptop is
15,000 times cheaper
10,000 times physically smaller
with 500 times more memory
and 1000 times more hard disk
and is 1500 times faster

Storing Microsoft Vista on a disk takes about 1.4 million
  times more space than was present on the lunar
  landing module on 20 July 1969.

                    Questions You Should Ask
                    (If You Haven’t Already)

What is computing all about?

Will there be jobs?

How much will I get paid?

Will I enjoy what I do?

(Why should I study computing at USC?)

                    Will There Be Jobs?         YES!!

Six of the ten fastest growing job areas are in

25,000 BS degrees per year, 1.4 million jobs
  between 2004 and 2014

Four times more new jobs in computing (2004-
  2014) than in all of engineering

Computer Science and Engineering   7   14 April 2010
            Perception, Reality, and the Media
2001: ―The predicted number of open jobs in IT
  has dropped 44% compared to last year.‖

True, but not the whole truth.

A) Predicted vacancies go from 1.4 million to
  about 950,000 (about a 44% drop, yes).

B) Predicted new hires in IT go from about
 250,000 to about 400,000.

Is (A) or (B) the more important point?

Computer Science and Engineering     9     14 April 2010
                      How Much Will I Get Paid?

Computer science has traditionally been in the top tier
  of all occupations (chemical engineering, electrical
  engineering, computer engineering, computer
  science, mechanical engineering) for starting salary

National average starting salary (BS) is about $52,000

The fastest growing jobs in computing are also among
  the highest paying jobs

―Computer and mathematical‖ is third highest paying of
  all occupational groups (averages, not starting)

                        Will I Enjoy What I Do?

―Software engineer‖ was rated the most satisfying job
  of all

―Computer/IT analyst‖ comes in number seven

There is satisfaction in doing well a difficult job that is
  constantly changing

Computing changes from one year to the next

Computing is not one job – it’s many

Look for your personal niche

Computer systems analyst
―I know you think you understand what you
  thought I said, but I don’t think you realize
  that what you heard is not what I meant.‖

Web apps and databases
Everyone wants applications to be browser
  enabled, with desktop clients, uniform
  interface, complete security, etc.

                      Some Jobs in Computing

Scientific computing
Small in terms of number of jobs, but very high in
  salary and job satisfaction (and lots more jobs than
  people available)
Dept of Energy (Los Alamos, Livermore, Oak Ridge, …),
Seismic processing in the oil industry
Airplane and auto industries

A roughly equal mix of computing, applied
  mathematics, and discipline science

              TRIESTE – (Trusted Radio Infrastructures for
                   Enforcing SpecTrum Etiquettes)

   Cognitive Radio – future wireless platform
       Expose the lower-layers (PHY) of the protocol stack to the
           scan the available spectrum
           select from a wide range of operating frequencies
           adjust modulation waveforms
           perform adaptive resource allocation

       An ideal platform for abuse, for example, for building jammers

   Goal: to regulate the future radio environment, ensure
    trustworthy radio operation

   How — two complementary mechanisms
       On-board enforcement – restricting any violation
        attempt from accessing the radio:
           running its own suite of spectrum etiquette protocols
           behaves according to acceptable communal policies
       An external monitor infrastructure:
           Distributed Spectrum Authority (DSA) — police
           agent observes the radio environment
           DSA will punish CRs if violations are detected.

                          Okay. I’m sold.

               I want to do computing.

                    How do I get there?

Computer Science and Engineering   26   14 April 2010
                          The Basic Game Plan

1. A solid technical background – because you
   won’t be able to fake it.

2. The ability to read, write, and present
   technical information – because the CEO is
   likely to be a nontechnical person.

3. The ability to work with people – because
   nearly all projects are bigger than just one
   person can do.

       What’s Your Second Favorite Thing?

Most people don’t just work on the computer—
 they use the computer to do something else.

Computer engineers deal with computing
 hardware, real-time, and the outside world.

Business applications people do business.

Computer scientists can do music, science,
 animation/graphics/art, biology, law, …

Computer Science and Engineering   28   14 April 2010
                                     Your Goals

Not just to be trained and get Microsoft/Oracle/Cisco
But to be educated in computing

Not to learn to be a lifelong programmer
But to know programming so you can manage
  programmers ten years from now

Not to be trained on today’s Package A
But to learn how to re-educate yourself with Package B
  in 2008, Package C in 2009, Package D in 2010, …
