Mining of Massive Datasets
Mining of Massive Datasets Anand Rajaraman Kosmix, Inc. Jeffrey D. Ullman Stanford Univ. Copyright c 2010, 2011 Anand Rajaraman and Jeffrey D. Ullman ii Preface This book evolved from material developed over several years by Anand Raja- raman and Jeff Ullman for a one-quarter course at Stanford. The course CS345A, titled “Web Mining,” was designed as an advanced graduate course, although it has become accessible and interesting to advanced undergraduates. What the Book Is About At the highest level of description, this book is about data mining. However, it focuses on data mining of very large amounts of data, that is, data so large it does not fit in main memory. Because of the emphasis on size, many of our examples are about the Web or data derived from the Web. Further, the book takes an algorithmic point of view: data mining is about applying algorithms to data, rather than using data to “train” a machine-learning engine of some sort. The principal topics covered are: 1. Distributed file systems and map-reduce as a tool for creating parallel algorithms that succeed on very large amounts of data. 2. Similarity search, including the key techniques of minhashing and locality- sensitive hashing. 3. Data-stream processing and specialized algorithms for dealing with data that arrives so fast it must be processed immediately or lost. 4. The technology of search engines, including Google’s PageRank, link-spam detection, and the hubs-and-authorities approach. 5. Frequent-itemset mining, including association rules, market-baskets, the A-Priori Algorithm and its improvements. 6. -

In this work, we present ICLab, an Internet measurement The simplest way to obtain vantage points is to recruit platform specialized for censorship research. It achieves a new balance between breadth of coverage and detail of measurements, volunteers [37], [43], [73], [80]. Volunteers can run software by using commercial VPNs as vantage points distributed around that performs arbitrary network measurements from each the world. ICLab has been operated continuously since late vantage point, but recruiting more than a few volunteers per 2016. It can currently detect DNS manipulation and TCP packet country and retaining them for long periods is difficult. Further, injection, and overt “block pages” however they are delivered. -

If you are using "Debian Squeeze" then please follow the new tutorial. A spanish translation of this tutorial is also available courtesy of José Ramón Magán Iglesias. What this tutorial is about You surely know the internet service providers that allow you to rent a domain and use it to receive emails. If you have a computer running Debian which is connected to the internet permanently you can do that yourself. You do not even need to have a fixed IP address thanks to dynamic DNS services like dyndns.org. All you need is this document, a cup of tea and a little time. When you are done your server will be able to... receive and store emails for your users from other mail servers let your users retrieve the email through IMAP and POP3 even with SSL to encrypt to connection receive and forward ("relay") email for your users if they are authenticated offer a webmail interface to read emails in a web browser detect most spam emails and filter them out or tag them License/Copyright This tutorial book is copyrighted 2009 Christoph Haas (email@christophhaas.de).

Special thanks to Gilbert Ashley, the author of src2pkg, for his approval and support throughout this redesign. Thanks to Piete Sartain for adminstrating the src2pkg wiki and Drew Ames for the writing much of the great documentation on the src2pkg wiki. I would also like to thank Dr. Alexander Dekhtyar for acting as my advisor for my rst senior project idea. Abstract Package managers ease installation and removal of applications. How- ever, as the name indicates, in order for a package manager to be useful, they need packages created from upstream sources to manage. This is the purpose of src2pkg, a toolkit written in Bash shell script which automates many package creation tasks. src2pkg, however, suers from major de- sign aws that cripple its ability to package some exotic upstream sources. -
