The document discusses the results of a survey conducted among computer science colleagues to identify the 5 most important algorithms. The survey yielded 32 algorithms across various fields like computer science, mathematics, signal processing and more. Some of the key algorithms identified include binary search, Dijkstra's algorithm, dynamic programming, Euclidean algorithm, gradient descent, maximum flow, merge sort, Newton's method, RSA encryption and singular value decomposition.
The document discusses Clay Shirky's ideas about how the internet allows for easier sharing, cooperation and collective action through new social tools. Shirky argues that the internet has changed how professions are viewed by allowing anyone to easily publish and distribute information, making even unimportant events more important. The information shared on the internet needs to be accurate, understandable and accessible to the public.
This document provides instructions for installing Subversion on Ubuntu with Apache, SSL, and BasicAuth. It describes how to install Subversion and Apache components, create SVN repositories, configure Apache, set up password authentication, and enable HTTPS access to the SVN repositories. The key steps are to create SVN databases under /var/svn, configure the dav_svn.conf file, set up password authentication with htpasswd, restart Apache, and test access over HTTPS.

The document provides instructions for installing Subversion on Ubuntu with Apache, SSL, and BasicAuth to allow hosting SVN repositories on a web server, including installing necessary packages, configuring Apache with a SSL certificate and virtual host, creating repositories under /var/svn, setting up authentication using htpasswd, and enabling WebDAV and SVN support in Apache.
Happiness is a journey, not a destination. The document discusses how people often tell themselves they will be happy once they achieve certain life goals or milestones, like getting married, having children, or retiring. However, challenges will always remain. True happiness is about finding contentment in the present moment and not waiting for the future to enjoy life. We must embrace each day as it comes and appreciate the time we have.
This document provides shortcuts and commands for Linux. It begins with essential shortcuts for switching between terminals and GUI screens. It then provides summaries of commands for getting system information, basic file operations, and networking. Examples are given for most commands.
This document provides a quick reference guide for Linux security that includes definitions of common security terms, general security tips, and Linux security resources. It defines terms like buffer overflow, cryptography, denial of service, and port scanning. It offers tips such as using automatic package managers to update software, configuring firewalls and intrusion detection, and enforcing strong password policies. The document also lists various security-related websites, books, and open source tools that can aid in hardening Linux systems.
