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, email, p2p, etc.– LAN, WiFi, cellular– Security and privacy– Search (do you google?)
ECS15 Xin Liu

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
ECS15 Xin 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 email? – Are you anonymous on the Internet?– How to keep yourself safe?
ECS15 Xin Liu

Are you anonymous on the Internet?
The above cartoon by Peter Steiner has been reproduced from The New Yorker, (Vol.69 (LXIX) no. 20) only for academic discussion.
ECS15 Xin 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)
ECS15 Xin 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…..
ECS15 Xin Liu

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.
ECS15 Xin 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
ECS15 Xin Liu
17
• Please include “ECS 15” in your subject line, to me and to TAs.
• Why? • One day response, TA/reader, myself.• If your requests not responded, let me
know.

Hi Gary, This is Shareen, from your Thursday discussion
section. I was wondering if you are going to be handing back the midterms this week?
Thanks, Shareen
It is also best to address your email to one person, possibly cc to others.

Where to get help• Course and term-paper related:
– https://piazza.com/ucdavis/fall2014/ecs15/home
• Lab related: – go to your labs sessions (highly recommended) or
Piazza.
• Term paper grading related: – William Dyer at [email protected]
• Lab grading related: – send to the grading TA of that lab
• Others: – Email one of the first two TAs or the instructor.
ECS15 Xin Liu

21
Grading• Grading
– Term paper (20%)• Computer in an area of your interest
– Lab assignments (35%)• 9 small projects (basic computer skills, basic programming)• No homework
– Midterm 20% (one mid-term)• Close book, one sheet of notes allowed• In class
– Final 25%• Close book, one sheet of notes allowed
ECS15 Xin Liu
22
Good Grade Guideline• Computers are rational
– Understand, not memorize• Active classroom participation• Do your own assignments
– Help you understand – Help you do well in exams– Help you in your later studies– Projects and term paper are “easy” grades.
• Sufficient time, sufficient help• Follow the lecture and notes• Final review
23
First Quarter Here?
• College is different, for most, very different• First year, and for some, second year, can
be very challenging• Course work and extra curriculum activities• A lot of freedom, independence, and
responsibilities• Growth is when one overcomes challenges.
ECS15 Xin Liu
24
Growth Mindset• Test your mindset: Intelligence is something about
a person that he/she can’t change very much.– Strongly agree to strongly disagree
• Fixed mindset vs. growth mindset• Can one learn to be good at computers?
– Yes, absolutely.– And yes, absolutely worth your time and effort
• Google “growth mindset” for more information.

25
Lab Session• Go to your registered Lab session if possible.• Priority goes to students registered in the lab session• TAs will be there the whole time to help you.• Joint with TAs’ office hours• Yes, you can go and ask any question related to the class. • Please let the TAs talk about the lab assignment first. • Lab assignments are posted two weeks in advance• All due on Friday 6pm, on smartsite• Grades posted one week after due date. • Please check your grade and TA comments (if any).

26
Computer Labs
• We have two computer labs you can use– SLB 2020 (where your lab sessions are)– Sometimes used by other classes– M 12:10-3 2060 SciLab
• Of course, you can also do everything on your own computer
