Lecture, Reading, and Assignment Calendar
Policy on Assignments and Independent Work.
Unless explicitly stated otherwise, all homeworks and projects are to be YOUR work and your work ALONE.
Collaboration in CS61C is limited to debugging. You should not discuss ideas/approaches or pseudocode with other students. What you hand in must be entirely your own work.
It is NOT acceptable to copy solutions from other students or to copy (or start your) solutions from the Web.
We have tools and methods, developed over many years, for detecting this.
You WILL be caught, and the penalties WILL be severe.
These include, at minimum:
A letter to your university record documenting the incidence of cheating.
An automatic F in the course for both you and the enabler/giver of the assignment.
Both the giver and receiver are equally culpable and suffer equal penalties.

If you have a question, here are the ways to get an answer, rated from best to worst:
Search for the answer yourself.& Far too often students ask a question whose answer is available on this very page or on the top of assignment handouts.
Ask a fellow classmate.
Look for your question on , then ask a new one if necessary.
Ask your TA during discussion section, lab, or office hours.
Ask Krste or Vladimir in office hours.
Ask Krste or Vladimir in lecture.
Send your TA email.
Send Krste or Vladimir an e-mail. Note that this is by far the worst way to ask a question. E-mail as a communications medium simply does not scale to ~400 students.

Floating Point Java Demos:
We will be using the fifth edition of Patterson and Hennessy's Computer Organization and Design book ("P&H"), ISBN .
We are also requiring The C Programming Language, Second Edition by Kernighan and Ritchie ("K&R"), and will reference its sections in the reading assignments.
Other books are also suitable if you are already comfortable with them, but our lectures will be based on K&R.
Finally, we will be using The Datacenter as a Computer: An Introduction to the Design of Warehouse-Scale Machines ("WSC"), which is freely available online .
The subjects covered in this course include:
C and assembly language programming,
how higher level programs are translated into machine language,
computer organization,
performance measurement,
parallelism,
CPU design,
warehouse-scale computing,
and related topics.
The only prerequisite is that you have taken CS61B, or at least have solid experience with a C-based programming language.
The course discussion forum is hosted by .
We will use this for asking and answering questions and making announcements.
