Active Directory Domain Services (AD DS) is the foundation for centralized management of an organization’s users and resources. As a Windows Server administrator, you must be able to implement AD DS.

In this computer science course, you will learn, through videos, discussions, hands-on labs and assessments, how to put in place a secure, scalable and manageable AD DS infrastructure for Windows Server users and resources.

This self-paced interactive computer science course is the first in a series of courses where you’ll have the opportunity to learn the fundamentals of Windows Server 2012 operating system administration.

One of the key components when you plan and deploy Microsoft Windows Server is storage. Most organizations require lots of storage because users and applications are constantly working with and creating data.

As a Microsoft Windows Server System Administrator you must be able to:  

• Identify and decide on the type of storage your organization needs
• Manage disks, volumes, and file systems
• Use BitLocker to secure volumes
• Encrypt data with Encrypted File System (EFS)

Furthermore, optimizing Microsoft Windows Server storage is key to keeping pace with your organization’s ever increasing data needs. Once you have initially configured your Microsoft Windows Server storage you will want to take advantage of three key features: iSCSI Storage, Storage Spaces and Data Deduplication.

iSCSI is a protocol that supports remote access to SCSI-based storage devices over a TCP/IP network. It provides and easy to use alternative to Storage Area Networks (SANs) and can use existing infrastructure.

Storage Spaces lets you group physical disks together and present them as a single logical disk. This makes it easy to manage and dynamically allocate storage.

Data Deduplication is a service that identifies and removes duplications within data. The goal of Data Deduplication is to maximize the use of disk space.

Go beyond simple storage strategies and take control of your organization’s storage needs!

This self-paced interactive computer science course is the second in a series of courses where you’ll have the opportunity to learn the fundamentals of Windows Server 2012 operating system administrative tasks. Through video, practical exercises, and assessments, the task-focused material is designed to ensure you can confidently perform the relevant task.

How do you design a mobile app that truly changes people's lives? How can you understand how a new service is being used, both quantitatively and qualitatively? How can you use all of the rich sensing and I/O capabilities of mobile devices to create experiences that go far beyond what's possible on a traditional computer?

Mobile devices are changing the ways that we interact with each other and information in the world. This course will take you from a domain of interest, through generative research, design, usability, implementation and field evaluation of a novel mobile experience. You'll finish the course with a working, field-tested application suitable for release in the app store as well as a deep understanding of human interaction with mobile devices and services.

Based on a popular MIT class that has been taught since 2006 by Frank Bentley of Yahoo Labs and Ed Barrett, a Senior Lecturer at MIT, this course will explore what makes mobile devices unique. A primary focus will be on studying existing behavior and using key findings for design. While writing the code for an app is a part of the class, the majority of the topics will cover designing and evaluating a unique mobile experience. Along the way, you will have opportunities to share your work with other students from around the world! Java experience (or Objective C for iOS users) and a smartphone are required.

All required readings are available within the courseware, courtesy of The MIT Press. A print version of the course textbook, Building Mobile Experiences, is also available for purchase. The MIT Press is offering enrolled students a special 30% discount on books ordered directly through the publisher’s website. To take advantage of this offer, please use promotion code BME30 at The MIT Press site.

Want to create the next big app, grounded in the needs of real users? This course will teach you Human Computer Interaction (HCI) methods to better understand current behavior in a domain, and then design, develop, and deploy your own application.

This module will take you from an application idea through the creation of a paper prototype and a usability evaluation to validate initial usability of your concept. 

Completion of Mobile Application Experiences Part 1 is not required. You can begin this module with an idea you have had on your own.

This course is part of a five-part Mobile Application Experiences series:

• 21W.789.1x: Mobile Application Experiences Part 1: From a Domain to an App Idea
• 21W.789.2x: Mobile Application Experiences Part 2: Mobile App Design

Learn to use the open development tool, App Inventor, to program on Android devices. You will learn how to design and build mobile apps -- apps that are aware of their location, send and receive text messages, and give advice and directions. The only limit on the types of apps you will learn to build is your own imagination!

However, computer science is not just about coding and building apps. We will also learn some of  the fundamental principles of computer science. We'll learn about the potential and the limitations of computing and coding. We'll learn how the Internet works and about the positive and negative aspects of computing in today's society, and much more!

For these broader computing concepts we will work within an emerging curricular framework -- the Computer Science Principles (CSP). The CSP framework is being developed by leading computer science educators from around the country under the auspices of the College Board and with funding support of the National Science Foundation.

In addition to programming and CSP the course is project-based and emphasizes writing, communication, and creativity. Multiple-choice questions, in the style that students can expect to encounter on the AP exam, will also be a key component of this course.

We will use the free and open tool, App Inventor for Android, to explore advanced topics in computer science.

You’ll build an app a week, exploring such advanced topics as gameplay over a network, encryption, and more.

At the end of the course, we’ll collectively decide on an app that we will build together. You will be able to build almost anything you can imagine!

Bringing together insights from physics, chemistry, biology, earth and atmospheric sciences -- and even some economics -- this course is geared to curious enthusiasts, allowing them to work with real climate data and simulations of the earth’s changing climate.
 
This eight-week class takes a quantitative approach to the science of global warming and will enable students to understand the greenhouse effect, the planet's carbon cycle, and how burning fossil fuel affects that cycle; and to evaluate the potential severity of humans’ impact on Earth’s climate.

Physical and digital design skills are key to practitioners in art, design, and engineering, as well as many other creative professions. Models are essential in architecture. In design practice all kinds of physical scale models and digital models are used side by side.

In this architecture course, you will gain experience that will help and inspire you to advance in your personal and professional development. You will attain skills in a practical way. First, we will focus on sketch models for the early stages of a design process, then we will continue with virtual representations for design communication and finally more precise and detailed models will be used for further development of the ideas.

In the theoretical part of the course, you will learn about many different sorts of models: how architects use these and how they are essential in the design process.

The practical part of the course addresses a number of challenges. In small steps we will guide you through technical and creative difficulties in exciting, playful, and pleasant ways.

Examine how architecture reflects Japan’s history, starting with its emergence as a new nation in the 19th century and the building of the Western-style capital city of Tokyo on the foundations of Edo. New building materials and construction methods reflected changing times, and the radical contrast between tradition and modernism in the nation was clearly visible in Japan’s architecture and politics.

While experiencing intense Westernization pressures, Japan developed rapidly to rival the world’s great powers, we will look at how Japanese architects developed their own version of Modernism. Initially, Japanese wanted to pursue the discoveries of the Franco-Swiss Le Corbusier and of Walter Gropius at the German Bauhaus. But soon, Japan also began to produce its own 20th-century architects and develop its own style. Following World War II, Kenzo Tange became the first Japanese architect in history to achieve international fame.

In the last section of the course, we will present an interview-based case study titled “Exploring Tokyo Tech’s Twenty-First Century O-okayama Campus.” Tokyo Institute of Technology (aka Tokyo Tech) possesses its own unique and unbroken succession of practicing architects/professors, who design campus buildings. We will learn about Professor Kazuo Shinohara, one of the most prominent Japanese designers of the second half of the 20th century, and several of his renowned disciples from Tokyo Tech.

This course aims to illustrate the present state of Japanese Modernist and postmodern building, as well as the distance covered over the past 150 years, including the 130-year history of Tokyo Tech itself. Join us on this journey through time as we examine and admire Japan’s architecture to better understand Japanese history and politics.

Perhaps more than any other city, Alexandria has achieved a legendary literary status, and, in the twentieth-century in particular, has had writers of different nationalities immortalize it in literature.

In this course, we will explore the works of some writers whose names are associated with Alexandria, regardless of whether they were Alexandrians themselves or not. The writers we will discuss are C. P. Cavafy, E. M. Forster, Lawrence Durrell, Edwar al Kharrat, Ibrahim Abdel Meguid, Jaqueline Carol and Harry Tzalas.

The aim is to look at writers who bore different relations to the city: Alexandrians of foreign origins (Greek and Lebanese), Egyptian Alexandrians (an Orthodox Christian Copt and a Muslim) and foreigners who were only passing through (British), to explore how he or she represented the city in their works, or how Alexandria influenced their writing.

You’re acquainted with your DNA, but did you know that your cells synthesize enough DNA during your lifetime to stretch a lightyear in length? How does the cellular machinery accomplish such a feat without making more mistakes than you can survive? Why isn’t the incidence of cancer even higher than it is? And, if the DNA in each and every cell is two meters long, how is this genetic material compacted to fit inside the cell nucleus without becoming a tangled mess?

This course begins with an overview of the mortgage backed securities market.  We’ll learn about the characteristics of mortgage-backed securities and identify the factors that cause U.S. mortgage-backed securities to be considered a different category of fixed income securities compared to asset-backed securities.

We’ll learn about the U.S. mortgage agencies and be able to distinguish among them regarding their legal status, nature of the guarantees they offer and types of mortgages they securitize. We’ll look at the basic features of agency pass-through securities and collateralized mortgage obligations (CMOs) and how their structural differences impact cash flows received by investors. We’ll also get familiarized with mortgage-related terminology such as non-recourse debt, underwater mortgages and short sales as well as their implications for mortgage loans and their consequences for the risk and expected returns to investors in mortgage-backed securities and learn about the main aspects involved in the creation of an agency pass-through security.

We’ll learn about mortgage cash flows and prepayments and also learn how the interaction between prepayment risk and reinvestment risk adversely impacts holders of pass-through securities in both rising and falling interest rate environments. We’ll learn how to distinguish between rate of return and the different yields associated with mortgage-backed securities and get introduced to the commonly used prepayment benchmarks for expressing prepayment speeds. We’ll wrap up this course with an understanding of bond math, spreads used in assessing the risk and relative value, option-adjusted spread and collateralized mortgage obligations.

This course is part 1 of the New York Institute of Finance’s Mortgage Backed Securities (MBS) Professional Certificate program.

In this course we’ll learn the key features of the most common types of tranches in agency CMOs:

• Z (accrual) bond tranches
• PAC (planned amortization class) tranches
• TAC (targeted amortization class) tranches

We’ll cover the primary differences between non-agency and agency CMOs and identify the main types of internal credit enhancements commonly used in non-agency CMOs. We’ll also learn how to contrast credit risk, prepayment risk and the typical amount of credit enhancements for different types of collateral, especially prime jumbo and subprime mortgage securitizations.

Next, we’ll look at the structure and purpose for creating Giants (FHLMC), Megas (FNMA) and Platinum securities (GNMA) and understand what we mean by reverse mortgages. We’ll review the structural similarities and differences of commercial mortgage-backed securities (CMBS) with both agency and non-agency CMOs and look at the common features of the structured payouts on CMBS including IO strips and super-senior tranches.

This course also describes types of agency multi-family securitizations, the various ways of structuring the collateral pool and the payouts to investors and the characteristics of TBA (to be announced) trading and specified (spec) trading. We’ll review the factors that cause the prices of specified trades and TBA trades to differ, and the forward pricing of TBA trades based on (cost of) carry considerations, structure of a dollar roll, and the factors that determine the attractiveness of dollar rolls to investors holding MBS. We’ll wrap up this course with an understanding of ARMs (Adjustable Rate Mortgages) and Hybrids (Hybrid Adjustable Rate Mortgages).

This course is part 2 of the New York Institute of Finance’s Mortgage Backed Securities (MBS) Professional Certificate program. This course will begin with a review of the first course in this program, Mortgage Backed Securities (MBS): Part I.
