15-446 Networked Systems Practicum
Lecture 1 – Introduction
1
Today’s Lecture
• Administrivia
• Topics and Overview
2
Instructors
• Instructors.• Srini Seshan
• srini@cs.cmu.edu, Gates Hall 8123
• Teaching assistants.• None (a couple informal ones )
3
Course Goals
• Learn about mobile system design• Wireless networks• Energy management• Split application design
• Learn about security for networked systems• Basic crypto techniques• Privacy challenges in mobile systems• DDoS
• Learn how to build systems that use the network• Capstone project
4
Course Format
• ~20 lectures• Cover the “principles and practice”• Complete readings before lecture• Readings based on recent systems/research papers
• 4 homework assignments• “Paper”: Do you understand and can you apply the material?• “Lab”: learn key system concepts
• Capstone-like project
• Midterm and final• Covers each of the above 3 parts of class
5
Project
• Topic of your choice• Discussion of topics next lecture• Should have something to do with mobile computing
• Regular meetings (approximately 1 per 4 weeks)
• Final handin: code, presentation + demo, short (few page) writeup
• Solo or in groups of 2• Both students should understand the entire project• Expectations of groups will be somewhat higher
6
Administrative Stuff
• Watch the course web page• http://www.cs.cmu.edu/~srini/15-446/F11/• Handouts, readings, ..
• Piazza for Q&A
• Office hours by appointment
• Course secretary• Angela Miller, Gates 9118
7
Grading
• Roughly equal weight in projects and testing• 45% for Project• 15% for Midterm exam• 20% for Final exam • 20% for Homework/Participation
• You MUST demonstrate competence in both projects and tests to pass the course• Fail either and you fail the class!
8
Policy on Collaboration
• Working together is important• Discuss course material in general terms• Work together on program debugging, ..• Final submission must be your own work
• Homeworks, midterm, final
• Web page has details
9
Late Work and Regrading
• Late work will receive a 15% penalty/day• No assignment can be more than 2 days late• No penalty for a limited number of handins - see web
page• Only exception is documented illness and family
emergencies
• No assignments with a “short fuse”• Start on time!
