Essential Scale-Out Computing
by James Cuff
Each day you interact with thousands upon thousands of processors, servers, storage systems and high-speed networks. You don’t see them, and you don’t physically touch them, but they are there, making everything happen behind the scenes. Everything is powered by advanced computing, from your morning news, movie and video streams, phone conversations, currency, financial markets, pharmaceuticals, navigation, traffic, weather, email and of course all of our social media updates. Each of us consumes vast amounts of data and computation on a daily basis. We also continue to push the boundaries of our science and discovery. Using ever more complex computer models to peer into the darkness of space or to understanding the genetic basis as to why were are human. All of this needs computing for it to work correctly, and it also needs advanced infrastructure and distributed computing architectures to work quickly. James Cuff is the Assistant Dean for Research Computing here at Harvard. His group runs more than sixty thousand high performance computing processors and more than fourteen petabytes of storage for science. On a global scale, this system is tiny. However, he will show you real world examples of the advances in computation science, physical infrastructure and distributed computing systems we are using each day, whether you are a particle physicist trying to reverse engineer the very fabric of the universe – or maybe you are just updating your selfie… So what will you learn from this seminar? You are all designing software for your final project. Facebook for example, was originally designed as a small single server PHP application. In order to make it scale to today’s hundreds of thousands of servers and billions of users took years. James will explain how both datacenter and systems architectures that now surpass electrical power usage of 10-20 megawatts – (enough to power more than 20,000 houses, nearly half of the City of Cambridge) enable today’s applications to scale. Each computation, be it add, subtract, multiply, divide, strcmp(), grep or memory hash lookup you make in your application now matters. You will be shown not only how distributed computing factors into your applications, but also how the actual energy efficiency of your algorithms matters. Designing, and thinking about how your application will scale from the beginning to potentially manage 10,000’s of page impressions a second is now the new normal.

Surviving the Internet
by Esmond Kane
This seminar will be a truncated version of the National Cyber Security Awareness Month presentations available here: http://hvrd.me/Rx1Se9 During this year, a record number of popular online service providers, ranging from email, to social media, to cloud file sharing, were compromised resulting in our data being exposed. Now, more than ever, we need to be mindful of the need for constant vigilance when it comes to computer security. To protect yourself from cyber risks, here are some things you can do: 1. Ensure your computer has been set to automatically update 2. Enable your computer’s operating system firewall 3. Install antivirus software and ensure it is set to automatically update 4. Install HTTPS and anti-tracking extensions 5. Only save your passwords to a password safe, never save passwords to your browser 6. Select a unique password for each of your accounts, do not use a common password for all of your accounts 7. Use two-factor authentication for accounts that offer it, for example, Google, PayPal, Dropbox, Facebook and many others offer free or low cost two-factor authentication 8. Be suspicious of opening email you were not expecting, or from someone you do not know, and never reply to an email asking for your password 9. Consider encrypting your hard disk using your computer’s operating system encryption program, for example, FileVault or BitLocker 10. Back up your hard disk; make a local backup AND make an online backup of important data.

Unix Shells, Environments
by Douglas Kline
Unix shells consist of and depend on environments and other provisions that differ from those of other operating systems. Unix offers several different shells which have some things in common with each other. One, bash, is now becoming available on other operating systems and may become shell-lingua franca. Understanding the bases of the shells, their various capabilities, and how they differ from each other can greatly increase one’s capabilities of using Unix and also illustrate the history and development of the shells and the operating system in general. Understanding how they differ from shells of other operating systems can promote understanding of both and forestall confusion and mistakes. I intend this primarily as a practical seminar as the topic isn’t really theoretical and the broader historical implications have more to do with the irregular, idiosyncratic origins of Unix rather than principles of computer science.
Vim: Speed and Power at your Fingertips
by Brandon Liu '14
Vim is one of the most popular text editors used by programmers.

Accelerating Science with the Open Science Grid
by Ian Stokes-Rees
In the mid-1990s, the high-energy physics community (think FermiLab and CERN) started planning for the Large Hadron Collider. Managing the petabytes of data that would be generated by the facility and sharing it with the globally distributed community of over 10,000 researchers would be a major infrastructure and technology problem. This same community that brought us the web has now developed standards, software, and infrastructure for grid computing. In this seminar I’ll present some of the exciting science that is being done on the Open Science Grid, the US national cyberinfrastructure linking 60 institutions (Harvard included) into a massive distributed computing and data processing system.
Acing Your Technical Interviews
by Tony Ho '14
At Harvard, there aren’t many programs that help people practice their interviews, especially if there is coding involved. To help with this, I would like to teach people about resources that are out there that can help with making sure everyone can ace their interviews.
Most coding interviews are like another coding competition. I would like to start by talking about resources like Project Euler, Poj, USACO, Codeforces, Topcoder. Then I will move into the broad topics that everyone needs to know to answer simple questions. Finally, I will end with a hands-on period where we will try some problems and go over some problems that I have personally seen and find very interesting.

SMS 101: Mobile Applications for ALL Types of Phones
by Jeff Solnet '12 and Punit Shah '12
This seminar will cover the basics of developing SMS-based mobile applications. We will discuss and demonstrate how to use the Zeep Mobile and TextMarks Lite APIs, in conjunction with PHP scripts, to develop interactive SMS applications. SMS (i.e. text messages) is a nearly-universal technology on cell phones. It allows developers to create mobile applications that are cheap and compatible with all phones, whether you’re using a smartphone (iPhone, Blackberry, G1) or your parents' old black-and-white Nokia. If you’re thinking about changing the world, SMS has been a useful platform for the developing world where few serviced populations have access to advanced mobile devices. Farmers in many African countries are now able to get up-to-date pricing and other agricultural data thanks to SMS applications. In Kenya, mobile (SMS) banking is rapidly changing the way Kenyans create and conduct business. Whether you’re interested in updating Shuttleboy or solving world peace, this seminar will be a good starting point.

Building Social Applications with the Facebook Platform
by Keito Uchiyama '11
When you "SuperPoke" someone on Facebook or play "Farmville", you’re using applications built on the Facebook Platform, an extensive infrastructure designed to make it easy for developers to leverage the social graph of the world’s largest social networking website. Now that the Facebook Platform is available outside facebook.com as Facebook Connect and in many other languages beyond PHP, an increasingly large number of notable websites are using the Platform to add the social element to their websites and other applications. Learn how to create such an application yourself and join the social web.
Dynamic Websites on Rails
by Greg Brockman
Ruby on Rails is a framework for building web applications that makes complicated tasks easy, fast, and fun. By taking care of low-level details such as talking to your database as if it were an object, Rails frees you to deal with the interesting parts that make your site unique to you. In this talk, we’ll go through some of the basic concepts of Rails, ultimately building a dynamic application in mere minutes. Give in to peer pressure and join sites like Hulu, Twitter, and Jobster in riding the Rails.
Hadoop for Large-Scale Computation
by Zak Stone '04
Welcome to the era of Big Data, in which petabytes of information are accumulating at an accelerating rate and desperately need you to analyze them. Computation on billions of web pages or photos or log entries requires new tools and a new way of thinking about programming; this seminar will introduce you to Hadoop, the most prominent open-source ecosystem of tools for working with exciting new large-scale datasets.
Interactive Data Applications
by Mike Tucker '03
Endeca provides a platform for search applications that allows users to navigate through data based on record attributes. This means that you can take any dataset that you have in mind and open it up to the world with the type of high quality text search and faceted navigation that you find on the top e-commerce and media sites including HomeDepot.com, NewEgg.com, NewsSift.com and Time.com.
Endeca provides access to these features and more through APIs that are exposed in a standard query language for XML databases called XQuery, in which you can write arbitrarily complex programs. These programs can then be hosted in your Endeca application as web-services, meaning that they can be invoked from your Ajax or Flex-based User Interface.
Scraping Data from the Internet
by Keito Uchiyama '11
Stocks, sports scores, dining menus—there’s a plethora of information out there on the Internet that’s not available by easily accessible Application Programming Interfaces (APIs). Web scraping, or screen scraping in general, helps extract that data by parsing the HTML on web pages, making data from any website on the Internet accessible to your application and prime for mashing up in whatever creative way you can imagine. We’ll go over an example, CrimsonDining.org, which uses robust scraping to retrieve menu data from Dining Services. The techniques covered in this seminar will apply to any programming language or framework.
Visualizing Data and Data Art with Processing
by Filip Zembowicz '11
Processing is an open-source programming language based on Java and designed with visualization in mind. It is for students, artists, designers, researchers, and hobbyists for learning, prototyping, and production of graphics, both static and interactive. It is used intensively in the class CS 171: Visualization, taught by Hanspeter Pfister. This tutorial will cover basic processing fundamentals, including loading data, drawing complex shapes from primitives, physics, and handling user interaction. These programs can then be run online or through downloadable executables.
Visualizing Data Interactively: A Primer on Actionscript, Flex, and the Flare Visualization Library
by Filip Zembowicz '11
Large datasets are everywhere nowadays: information on populations, biology, voting, prices, and distances are just a few of the various categories of data easily accessible online. However, many of these resources suffer from poor user interface design—it is hard for a user to see the information holistically, to see patterns in data, to observe how the data changes over time, and to remain engaged with static blocks of text and images. Information visualization allows for the facile design of engaging ways to explore data. In this tutorial, I will introduce Actionscript (the language that powers Flash animations) and Flex (an Adobe product that allows rapid development of web-based flash apps), specifically focusing on how the Flare visualization library can be utilized to load, display, and interact with quantitative, qualitative, and relative data. Examples of beautiful visualizations: http://www.visualcomplexity.com/vc/.
Adobe has recently announced that the forthcoming Flash CS5 will be able to run on iPhone — this represents a tremendous opportunity for getting into the mobile wave.
