Evolution of the Product Manager

  Ellen Chisa

Better education needed to develop the discipline

Software practitioners know that product management is a key piece of software development. Product managers talk to users to help figure out what to build, define requirements, and write functional specifications. They work closely with engineers throughout the process of building software. They serve as a sounding board for ideas, help balance the schedule when technical challenges occur - and push back to executive teams when technical revisions are needed. Product managers are involved from before the first code is written, until after it goes out the door.

Privacy, Anonymity, and Big Data
in the Social Sciences

  Jon P. Daries, Justin Reich, Jim Waldo, Elise M. Young, Jonathan Whittinghill, Daniel Thomas Seaton, Andrew Dean Ho, Isaac Chuang

Quality social science research and the privacy of human subjects requires trust.

Open data has tremendous potential for science, but, in human subjects research, there is a tension between privacy and releasing high-quality open data. Federal law governing student privacy and the release of student records suggests that anonymizing student data protects student privacy. Guided by this standard, we de-identified and released a data set from 16 MOOCs (massive open online courses) from MITx and HarvardX on the edX platform. In this article, we show that these and other de-identification procedures necessitate changes to data sets that threaten replication and extension of baseline analyses. To balance student privacy and the benefits of open data, we suggest focusing on protecting privacy without anonymizing data by instead expanding policies that compel researchers to uphold the privacy of the subjects in open data sets. If we want to have high-quality social science research and also protect the privacy of human subjects, we must eventually have trust in researchers. Otherwise, we'll always have the strict tradeoff between anonymity and science illustrated here.

Undergraduate Software Engineering: Addressing the Needs of Professional Software Development

  Michael J. Lutz, J. Fernando Naveda, James R. Vallino

Addressing the Needs of Professional Software Development

In the fall semester of 1996 RIT (Rochester Institute of Technology) launched the first undergraduate software engineering program in the United States. 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.

Looking at the design and benefits of X10

In 2002 DARPA (Defense Advanced Research Projects Agency) launched a major initiative in HPCS (high-productivity computing systems). The program was motivated by the belief that the utilization of the coming generation of parallel machines was gated by the difficulty of writing, debugging, tuning, and maintaining software at peta scale.

JavaScript and the Netflix User Interface

  Alex Liu

Conditional dependency resolution

In the two decades since its introduction, JavaScript has become the de facto official language of the Web. JavaScript trumps every other language when it comes to the number of runtime environments in the wild. Nearly every consumer hardware device on the market today supports the language in some way. While this is done most commonly through the integration of a Web browser application, many devices now also support Web views natively as part of the operating system UI (user interface). Across most platforms (phones, tablets, TVs, and game consoles), the Netflix UI, for example, is written almost entirely in JavaScript.

Port Squatting

  George V. Neville-Neil

Don't irk your local sysadmin

Dear KV, A few years ago you upbraided some developers for not following the correct process when requesting a reserved network port from IETF (Internet Engineering Task Force). While I get that squatting a used port is poor practice, I wonder if you, yourself, have ever tried to get IETF to allocate a port. We recently went through this with a new protocol on an open-source project, and it was a nontrivial and frustrating exercise. While I wouldn't encourage your readers to squat ports, I can see why they might just look for unallocated ports on their own and simply start using those, with the expectation that if their protocols proved popular, they would be granted the allocations later.

Security Collapse in the HTTPS Market

  Axel Arnbak, Hadi Asghari, Michel Van Eeten, Nico Van Eijk

Assessing legal and technical solutions to secure HTTPS

HTTPS (Hypertext Transfer Protocol Secure) has evolved into the de facto standard for secure Web browsing. Through the certificate-based authentication protocol, Web services and Internet users first authenticate one another ("shake hands") using a TLS/SSL certificate, encrypt Web communications end-to-end, and show a padlock in the browser to signal that a communication is secure. In recent years, HTTPS has become an essential technology to protect social, political, and economic activities online.

Why Is It Taking So Long to Secure Internet Routing?

  Sharon Goldberg

Routing security incidents can still slip past deployed security defenses.

BGP (Border Gateway Protocol) is the glue that sticks the Internet together, enabling data communications between large networks operated by different organizations. BGP makes Internet communications global by setting up routes for traffic between organizations—for example, from Boston University's network, through larger ISPs (Internet service providers) such as Level3, Pakistan Telecom, and China Telecom, then on to residential networks such as Comcast or enterprise networks such as Bank of America.

Certificate Transparency

Public, verifiable, append-only logs

On August 28, 2011, a mis-issued wildcard HTTPS certificate for was used to conduct a man-in-the-middle attack against multiple users in Iran. The certificate had been issued by a Dutch CA (certificate authority) known as DigiNotar, a subsidiary of VASCO Data Security International. Later analysis showed that DigiNotar had been aware of the breach in its systems for more than a month—since at least July 19. It also showed that at least 531 fraudulent certificates had been issued. The final count may never be known, since DigiNotar did not have records of all the mis-issued certificates. On September 20, 2011, DigiNotar was declared bankrupt.

ACM and the Professional Programmer

  Vinton G. Cerf

How do you, the reader, stay informed about research that influences your work?

In the very early days of computing, professional programming was nearly synonymous with academic research because computers tended to be devices that existed only or largely in academic settings. As computers became commercially available, they began to be found in private-sector, business environments. The 1950s and 1960s brought computing in the form of automation and data processing to the private sector, and along with this came a growing community of professionals whose focus on computing was pragmatic and production-oriented. Computing was (and still is) evolving, and the academic community continued to explore new software and hardware concepts and constructs. New languages were invented (and are still being invented) to try new ideas in the formulation of programs. The introduction of time sharing created new territory to explore. In today's world cloud computing is the new time sharing, more or less.
