ECS15Xin Liu 8 Road Map Computers (3-4 weeks) –Hardware: motherboard, processor, memory, I/O devices, etc. –Software and application: –Graphics: image, video, 2D, 3D, game, –History and ethics Python Programming (3-4 weeks) –Getting started –Basic concepts: type, variable, I/O –Loops: while, for, if The Internet (2-3 weeks) –Layered architecture, web, , p2p, etc. –LAN, WiFi, cellular –Security and privacy –Search (do you google?)

ECS15Xin Liu 9 Why does this help? Computer Literacy Basic knowledge of computers –Understand basic hardware/software components –Order a computer –Configure your wireless router Basic understanding of software tools –Word process, ppt, excel, access, etc. –How to use them to your benefits –How to learn new tools

ECS15Xin Liu 10 Why does this help? Internet drastically changes the world –Business, work, social, life, family, shopping, entertainment, etc. What do these things mean? –Wikipedia, Web 2.0, Long tail Internet is reaching beyond PCs Security and privacy –IRS sending you an ? –Are you anonymous on the Internet? –How to keep yourself safe?

ECS15Xin Liu 11 Are you anonymous on the Internet? The above cartoon by Peter Steiner has been reproduced from The New Yorker, (Vol.69 (LXIX) no. 20)The New Yorker, only for academic discussion.

ECS15Xin Liu 12 Why Programming What is a program? You can handle little problems yourself You know when you hire someone how big a job it is (like going to a mechanic) You have some idea of what is possible. A good programmer has more job options (you’ll need more than this one class, though)

ECS15Xin Liu 13 Why Python? Useful and popular –Great for interfacing one program to another –Widely used in industry –Google, ILM, NASA…. Free Easy to get started with –Lots of “libraries” (add-ons) that do things like sound editing, computational biology, Web database access…..

ECS15Xin Liu 14 It teaches you to think! The computer is your genie in a bottle –It can be your best help –It can be really frustration It does exactly what you tell it to Your job is to figure out what/how to tell it. Learning the language is easy, … Some people really like it!

ECS15Xin Liu 15 Other options ECS 10: Programming in Python –You will get full credit (after taking ECS 15) –GE class ECS 30: More intensive class for those with some programming experience (basic, c, java), learn C++, required for ECS majors.

ECS15Xin Liu 16 Class Policy All lab assignments require individual efforts. Discussions are allowed, copying NOT. Late policy –Full credit if on time –50% if within 24 hours –0 after 24 hours Regrading Policy –One week regrading period after grades returned to students Incomplete will not be granted –Unless proved emergency with filled emergency form Academic Integrity –Writing, commercial software for checking plagiarism –Lab assignments
