A Brief History of Cryptography http://www.slideshare.net/guest9006ab/a-brief-history-of-cryptography
We use it every day and we rely on it. But what are the roots of cryptography? How were, for example, the ancient Greeks able to protect information from their enemies? In this talk we will go through 5500 years of developing encryption technologies and look at how these work. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/).

Eigenvalues in a Nutshell http://www.slideshare.net/guest9006ab/eigenvalues-in-a-nutshell
Although eigenvalues are one of the most important concepts in linear algebra, some of us eigen-struggle with them without understanding their usefulness and beauty. In this talk I’ll briefly review the definition of eigenvalues emphasizing the associated geometric idea and I’ll show how can they be used in some applications.

SMART Goals and Feedback (Project Management) http://www.slideshare.net/guest9006ab/smart-goals-and-feedback-project-management
Project Management is THE buzz word in business and more and more in academia. But managing things in projects does not guarantee success. Success and failure depends on people and communication. For this one of the most important things is the start and the end of a project. Setting goals at the start of the project ensures that everyone is working for the same thing. Feedback during and at the end of the project will provide everyone with very important information. We will interactively explore these topics which try to reduce misunderstanding and make projects more fun. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/).

C Code and the Art of Obfuscation http://www.slideshare.net/guest9006ab/c-code-and-the-art-of-obfuscation
In the early days of computer science coding was viewed as an art. In the modern world of software engineering we may have lost the art to make way for rules and best practices. The International Obfuscated C Code Contest offers a chance for the coder to think beyond the rules of software engineering and unleash their creative side. We’ll explore some of the more interesting entries in the past, take a closer look at some exotic C syntax, and finish up by exploring Bruce Holloway’s 1986 entry.

OS Mélange http://www.slideshare.net/guest9006ab/os-mlange
We are all mostly familiar with just Windows, Linux, Unix (along with all the Unix derives) and Mac OS as the primary Operating Systems available. There is a whole collection of operating systems out there, ranging from the amateur hobbyist’s take on conquering the OS world to full blown systems which either found a niche market or got doomed to oblivion. I shall attempt to present a small sample from this varied and interesting set. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/). The talk was given Feb. 9, 2007]]>

Human Nature and its Consequences http://www.slideshare.net/guest9006ab/human-nature-and-its-consequences
After looking at top-models in computer graphics last time, we make a 90° turn and look to the ’top-models’ of human nature. What did some famous philosophers think? Is the human nature ’bad’ (Hobbes) or ’good’ (Rousseau)? Do these models agree with today’s society and how we live today? Can they explain how we behave in daily life (e.g. why we are lazy or why we help each other)? I will give give several initiatory insights, giving us lots of material to discuss at Koerner’s.

Slipping the Surly Bonds http://www.slideshare.net/guest9006ab/slipping-the-surly-bonds
The very idea of flight has captivated humanity from the time of Icarus. I was bitten by the bug, got my license, and have done a fair bit of flying.

Communication with Extraterrestrial Intelligence http://www.slideshare.net/guest9006ab/communication-with-extraterrestrial-intelligence
SETI has been an active topic of research and media coverage during the recent decades. It involves looking for signals that could have been sent by an intelligent civilization as well as sending out signals to them. Effective communication with the aliens is a hard problem as they will probably have different languages for communication as we do. In this talk we will look at the various messages sent (and possibly received!) to our fellow cosmic inhabitants and the techniques proposed for effective communication with them. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/). The talk was given May 11, 2007.]]>

Signal Compression and JPEG http://www.slideshare.net/guest9006ab/signal-compression-and-jpeg
I will start with a question "why signal can be compressed?" I will then describe quantization, entropy-coding, difference-PCM, and Discrete Cosine Transform (DCT). My main motive will be to illustrate the basic principle rather than to describe the details of each method. Finally I will discuss how these various algorithm combined to get the JPEG standard for image compression. Time permitting, I will comment on various famous theories which lead to JPEG standard. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/). The talk was given May 18, 2007.]]>

Brain-Computer Interfaces http://www.slideshare.net/guest9006ab/braincomputer-interfaces
Aim of a brain-computer interface (BCI) is to provide a communication channel for paralyzed patients to interact with the outer world. I will start with the motivation behind brain-computer interfaces followed by description of a general BCI. I will then describe various kinds of BCI experiments and methods.

The ABC’s of the Bible http://www.slideshare.net/guest9006ab/the-abcs-of-the-bible
The Bible is the most copied, translated, and studied book ever written. It was composed by more than 40 authors from a variety of backgrounds and is used in many religions. But how many people have actually read it? Bible stories are often referenced or portrayed in the media today but it may be worth looking at the origins or those stories. In this talk we will examine the structure and layout of the Bible and give an overview of the history it provides. We’ll also look over some of the more interesting stories that it tells. From the Un-Distinguished Lecture Series (http://ws.cs.ubc.ca/~udls/). The talk was given Jun. 1, 2007.]]>
