In the fall semester of 1996 RIT (Rochester Institute of Technology) launched the first undergraduate software engineering program in the United States.9,10 The culmination of five years of planning, development, and review, the program was designed from the outset to prepare graduates for professional positions in commercial and industrial software development.

Many disparate use cases can be satisfied with a single storage system.
MARK CAVAGE AND DAVID PACHECO, JOYENT
While the term big data is vague enough to have lost much of its meaning, today’s storage systems are growing more quickly and managing more data than ever before. Consumer devices generate large numbers of photos, videos, and other large digital assets. Machines are rapidly catching up to humans in data generation through extensive recording of system logs and metrics, as well as applications such as video capture and genome sequencing. Large data sets are now commonplace, and people increasingly want to run sophisticated analyses on the data. In this article, big data refers to a corpus of data large enough to benefit significantly from parallel computation across a fleet of systems, where the efficient orchestration of the computation is itself a considerable challenge.

What do you do when your debugger fails you?
I’ve been assigned to help with a new project and have been looking over the admittedly skimpy documentation the team has placed on the internal wiki. I spent a day or so staring at what seemed to be a long list of open-source projects that they intend to integrate into the system they have been building, but I couldn’t find where their original work was described. I asked one of the project team members where I might find that documentation and was told that there really isn’t much that they need to document, because all the features they need are available in various projects on github.
I really don’t get why people do not understand that outsourcing work also means outsourcing responsibility, and that in a software project, responsibility and accountability are paramount.

How to generate funding for FOSS
The world runs on free and open-source software, FOSS for short, and to some degree it has predictably infiltrated just about any software-based product anywhere in the world.
What’s not to like about FOSS? Ready-to-run source code, ready to download, no license payments—just take it and run. There may be some fine print in the license to comply with but nothing too onerous or burdensome.

You must have some trust if you want to get anything done.
In his novel The Diamond Age,7 author Neal Stephenson describes a constructed society (called a phyle) based on extreme trust in one’s fellow members. Part of the membership requirements is that, from time to time, each member is called upon to undertake certain tasks to reinforce that trust. For example, a phyle member might be told to go to a particular location at the top of a cliff at a specific time, where he will find bungee cords with ankle harnesses attached. The other ends of the cords trail off into the bushes. At the appointed time he is to fasten the harnesses to his ankles and jump off the cliff. He has to trust that the unseen fellow phyle member who was assigned the job of securing the other end of the bungee to a stout tree actually did his job; otherwise, he will plummet to his death. A third member secretly watches to make sure the first two don’t communicate in any way, relying only on trust to keep tragedy at bay.

To millions of game geeks, the position of QA (quality assurance) tester at Electronic Arts must seem like a dream job. But from the company’s perspective, the overhead associated with QA can look downright frightening, particularly in an era of massively multiplayer games.

High-level DSLs for low-level programming
BO JOEL SVENSSON, INDIANA UNIVERSITY

DSLs (domain-specific languages) make programs shorter and easier to write. They can be stand-alone—for example, LaTeX, Makefiles, and SQL—or they can be embedded in a host language. You might think that DSLs embedded in high-level languages would be abstract or mathematically oriented, far from the nitty-gritty of low-level programming. This is not the case. This article demonstrates how high-level EDSLs (embedded DSLs) really can ease low-level programming. There is no contradiction.

If you see something, say something.
In February Apple revealed and fixed an SSL (Secure Sockets Layer) vulnerability that had gone undiscovered since the release of iOS 6.0 in September 2012. It left users vulnerable to man-in-the-middle attacks thanks to a short circuit in the SSL/TLS (Transport Layer Security) handshake algorithm introduced by the duplication of agoto statement. Since the discovery of this very serious bug, many people have written about potential causes. A close inspection of the code, however, reveals not only how a unit test could have been written to catch the bug, but also how to refactor the existing code to make the algorithm testable—as well as more clues to the nature of the error and the environment that produced it.

Looking at embedded DSLs
ANDY GILL, UNIVERSITY OF KANSAS
There are many ways to give instructions to a computer: an electrical engineer might write a MATLAB program; a database administrator might write an SQL script; a hardware engineer might write in Verilog; and an accountant might write a spreadsheet with embedded formulas. Aside from the difference in language used in each of these examples, there is an important difference in form andidiom. Each uses a language customized to the job at hand, and each builds computational requests in a form both familiar and productive for programmers (although accountants may not think of themselves as programmers). In short, each of these examples uses a DSL (domain-specific language).

How good security at the NSA could have stopped him
Edward Snowden, while an NSA (National Security Agency) contractor at Booz Allen Hamilton in Hawaii, copied up to 1.7 million top-secret and above documents, smuggling copies on a thumb drive out of the secure facility in which he worked, and later released many to the press. This has altered the relationship of the U.S. government with the American people, as well as with other countries. This article examines the computer security aspects of how the NSA could have prevented this, perhaps the most damaging breach of secrets in U.S. history. The accompanying sidebar looks at the Constitutional, legal, and moral issues.
