Python - a Crash Course
Python - A Crash Course Antonio Lima Networks and Distributed Systems 2012-2013 School of Computer Science - University of Birmingham 15 March 2013 Last week's Homework Write a Python program that counts the occurrences of words in a wordlist. counter = {} with open(filename, "r") as f: for line in f: if line in counter: counter[line] += 1 else: counter[line] = 1 We are asking permission. It's easier to ask forgiveness. Last week's Homework You ask forgiveness by executing a task and recovering if there is an error. counter = {} with open(filename, "r") as f: for line in f: try: counter[line] += 1 except KeyError: counter[line] = 1 That's much better (one operation less). But there's even a more pythonic solution. Last week's Homework You ask forgiveness by executing a task and recovering if there is an error. import collections counter = collections.defaultdict(int) with open(filename, "r") as f: for line in f: counter[line] += 1 5 lines, very readable, correct. Pythonic. Why using Python for Networking? • Well, why not? • Many successful companies/startups are using it. • Google, Yahoo, Dropbox, Quora, Disqus, ... • A lot of libraries are available. • You can build prototypes quickly.

Master Thesis
MASTER THESIS TITLE: Analysis and evaluation of high performance web servers MASTER DEGREE: Master in Science in Telecommunication Engineering & Management AUTHOR: Albert Hidalgo Barea DIRECTOR: Rubén González Blanco SUPERVISOR: Roc Meseguer Pallarès DATE: July 13 th 2011 Title: Analysis and evaluation of high performance web servers Author: Albert Hidalgo Barea Director: Rubén González Blanco Supervisor: Roc Meseguer Pallarès Date: July 13 th 2011 Overview Web servers are a very important tool when providing users with requested content on the Internet. Usage of the Internet is growing day-by-day, making those software applications essential. In the first part of the thesis, the web server world will be introduced to the reader, by giving a brief explanation of some of the available technologies as well as different dynamic protocols. Also, as there are different web servers available in the market, during this report it will be chosen the best performing ones. So, it will be presented a comparative chart between all of them in order to show the most important features of each one. Defining the scenario and the test cases is mandatory. For this reason, it is described the used hardware and software used to perform those benchmarks. The hardware is maintained equal during the whole test process, in order to let web server’s performance gaps to their internal architecture. Operating system and benchmarking tools are also described and given some examples. Furthermore, test cases are chosen to show some strengths and weakness of each web server, enabling us to compare the relative performance between them. Finally, the last part of the report consists on presenting the obtained results during the benchmark process, as well as presenting some lessons learned during the curse of the whole thesis, summing-up with some conclusions.

An Introduction to Python for Absolute Beginners
An introduction to Python for absolute beginners Bob Dowling University Computing Service [email protected] http://www.ucs.cam.ac.uk/docs/course-notes/unix-courses/PythonAB 1 Welcome to the Computing Service's course “Introduction to Python”. This course is designed for people with absolutely no experience of programming. If you have any experience in programming other languages you are going to find this course extremely boring and you would be better off attending our course "Python for Programmers" where we teach you how to convert what you know from other programming languages to Python. This course is based around Python version 3. Python has recently undergone a change from Python 2 to Python 3 and there are some incompatibilities between the two versions. The older versions of this course were based around Python 2 but this course is built on Python 3. Python is named after Monty Python and its famous flying circus, not the snake. It is a trademark of the Python Software Foundation. 1 Course outline ― 1 Who uses Python & what for What sort of language it is How to launch Python Python scripts Text Names for values Reading in user data Numbers Conversions Comparisons Truth & Falsehood 2 2 Course outline ― 2 Assignment Names Our first “real” program Loops if… else… Indentation Comments 3 3 Course outline ― 3 Lists Indices Lengths Changing items Extending lists Methods Creating lists Testing lists Removing from lists for… loop Iterables Slices 4 4 Course outline ― 4 Files Reading & writing Writing our own functions

Abstract GEGICK, MICHAEL CHARLES. Analyzing Security
Abstract GEGICK, MICHAEL CHARLES. Analyzing Security Attacks to Generate Signatures from Vulnerable Architectural Patterns. (Under the direction of Dr. Laurie Williams.) Current techniques for software security vulnerability identification include the use of abstract, graph-based models to represent information about an attack. These models can be in the form of attack trees or attack nets and can be accompanied with a supporting text- based profile. Matching the abstract models to specific system architectures for effective vulnerability identification can be a challenging process. This thesis suggests that abstract regular expressions can be used to represent events of known attacks for the identification of security vulnerabilities in future applications. The process of matching the events in the regular expression to a sequence of components in a system design may facilitate the means of identifying vulnerabilities. Performing the approach in the design phase of a software process encourages security to be integrated early into a software application. Students in an undergraduate security course demonstrated a strong ability to accurately match regular expressions to a system design. The identification of vulnerabilities is limited to known attacks of other systems and does not offer descriptions of what new attacks are possible to a future application. Extending the approach to incorporate new attacks is an avenue of future work. Analyzing Security Attacks to Generate Signatures from Vulnerable Architectural Patterns by Michael Charles
