The Textbook

• Great book, if I may say so
• But it's getting a bit outdated
• I am revising the book this academic year
• You'll get draft pages here as the semester progresses
• Don't post them anywhere!
• No need to buy a printed book

What You Need to Succeed

Prerequisites

• CS1/CS2: Loops, arrays, input/output, sets and maps, etc.
• Java

Time

• You can't expect to learn complex skills just by listening to lectures
• Spend 9 hours per week for this class
  • 2.5 hours in class
  • 6.5 hours (!) outside class for preparation and homework

Laptop

• Bring it to each class meeting
• Be able to run a Bash shell

Questions

• Ask questions right away when you are stuck
• Use the online discussion group (Piazza).
• You'll get a better grade if you ask lots of questions.
• Answer your peers' questions. You'll get a better grade if you do.
• Private or confidential questions—email or office hours

Plagiarism and Cheating

• When you submit work, it must be your intellectual creation
• Can you copy and paste?
  • Always ok to copy—pasting is the problem ☺
  • Ok to use code from the problem statement or the textbook without attribution
  • Otherwise, you must attribute the source
• You can post snippets (but not a solution) on Piazza for critique
  • But you cannot copy from Piazza
• Don't email working code—you don't know what the recipient will do with it
  • Sending someone a solution is cheating
• I periodically run a plagiarism checker
• If I find cheating, I don't play Sherlock Holmes to find who wrote it—I report both
• I report everyone whom I find cheating to Student Conduct
  • I have to
  • And I will recommend that an appropriate penalty is for you to fail the course

Git

• You submit all class work via Git
• Make a private repo on BitBucket or GitHub
  • If you use your SJSU email address, BitBucket gives you a free account with unlimited private repos
• Add me as a contributor to your repo. My BitBucket and GitHub ids are cayhorstmann
• Use a single repo for all homework and exams
• Make folders hw1, hw2, exam1, ...
• Commit at least once a day for homework/every 10 min in an exam
• Push before midnight on due date. Grace period until 6am next morning. No mercy afterwards.
• Never used Git? Check out this CS46B lab.

Adding

• Do homework 1 and send me your answers.
• I will send you an add code when space becomes available. Use it within 24 hours, or it will become invalid
• Show up for all classes/labs even if you haven't received your code

Things To Do Today

• Log into Piazza
• Start reading the textbook
• Install Java 8 and Git on your laptop
• You need bash. If you run Windows 10, install the Windows Subsystem for Linux. If you run an older version of Windows, install VirtualBox and a Linux VM.
• Complete Homework 1 and send me your Git repo URL
• Important: In lieu of a roll call today, you must turn in homework 1, or I will drop you from this course for lack of presence/prerequisites.
