Today’s Outline• Background (mine)
• Engineering careers in general
• Embedded systems issues— why does everything break?
• Computers & their memory systems— how do I make my computer faster?
• Design as modern engineering entrepreneurship— my take on The World Is Flat … and guitars

(Who Is This Old Guy?)• High school (GA & FL): salutatorian,
three-season athlete, into rock, law, sci-fi
• College (Harvard): astr/math, A/B student, one-season athlete, into music, food, art
• Teaching (Thayer): high-school math
• Industry (BT, PCM): software developer, system architect (employee #2)
• Grad school (Michigan): computer software and hardware … research

Points to Take Home
• Engineering rocks
• Challenging & important problems exist
• Electrical engineering ≠ electricianComputer engineering ≠ programmer
• Anything that is in your head today can (should) be in your hands tomorrow
• People are willing to pay you to think(being smart is only a disadvantage now)

• Industry B.S. or M.S. Develop
• Industry/Research Ph.D. Design
• Academics Ph.D. Research Teach
Develop == BuildDesign == Justify Your Choices
Ph.Ds are paid to THINKMSs and BSs are paid to DO (mitigated by size of company)

Official Trapped in Car After Computer Fails Mon May 12, 2003 09:44 AM ET
BANGKOK (Reuters) - Security guards smashed their way into an official limousine with sledgehammers on Monday to rescue Thailand's finance minister after his car's computer failed.
Suchart Jaovisidha and his driver were trapped inside the BMW for more than 10 minutes before guards broke a window. All doors and windows had locked automatically when the computer crashed, and the air-conditioning stopped, officials said.
'We could hardly breathe for over 10 minutes,' Suchart told reporters. 'It took my guard a long time to realize that we really wanted the window smashed so that we could crawl out. It was a harrowing experience.'

![Page 51: R&D in Electrical & Computer Engineeringblj/talks/NSLC-2008.pdf · 2.8 ˚ 16 ˚ Pickup cavities are just deep enough to hold pickups. Pickups are screwed tightly into the neck wood](https://reader035.vdocuments.us/reader035/viewer/2022070900/5f3bea408f5b54381510c5b1/html5/thumbnails/51.jpg)
Pros & Cons
• Idea already proven in marketplace (shareware, boutique electronics)
• Win/win situation (even company failure is good résumé material)
• Low risk/reward ratio
• Start soon
• Can’t possibly compete with big companies
• Might fail
• Can’t afford it
• Window of opportunity?
Bottom line: a path well worth exploring

Points to Take Home
• Engineering rocks
• Challenging & important problems exist
• Electrical engineering ≠ electricianComputer engineering ≠ programmer
• Anything that is in your head today can (should) be in your hands tomorrow
• People are willing to pay you to think(being smart is only a disadvantage now)
