The End of a DBMS Era (Might Be ­Upon ­Us)

Relational database management systems (DBMSs) have been remarkably successful in capturing the DBMS marketplace. To a first approximation they are “the only game in town,” and the major vendors enjoy an overwhelming market share. They are selling “one size fits all”; i.e., a single relational engine appropriate for all DBMS needs. Moreover, the code line from all of the major vendors is quite elderly. Hence, the major vendors sell software that is a quarter century old, and has been extended and morphed to meet today’s needs. In my opinion, these legacy systems are at the end of their useful life.

Designing Effective Interfaces For ­Usable Privacy and Security

I often cringe when I hear highly technical engineers talk about people. I usually hear broad generalizations tossed about, like "people are lazy, that's why they can't use the system", or "people don't understand security". The worst is "people are just stupid". This lack of empathy is one of the main causes of poor user interface design today. With this in mind, I explore issues of user interface design for usable privacy and security, looking at the bigger picture of how to design useful, usable, and desirable interfaces in this space.

The Fallacy of Rankings

The list of the world's fastest computers will soon be announced. As always, we can expect the latest announcement to garner interest among the technological community, receive coverage in the popular press, and secure bragging rights for the organizations, vendors and countries involved. Though rankings (total orders) are intuitive and easily explained – a valuable attribute in today’s attention constrained society – they rarely capture the true complexity of multidimensional comparison. 

HPC: Making a Small Fortune

There is an old joke in the high-performance computing community that begins with a question, “How do you make a small fortune in high-performance computing?” There are several variations on the joke, but they all end with the same punch line, “Start with a large fortune and ship at least one generation of product. You will be left with a small fortune.” Forty years of experience, with companies large and small, has confirmed the sad truth of this statement. 

E-Government in Latin America

According to wikipedia: e-Government  is a diffused neologism used to refer to the use of information and communication technology to provide and improve government services, transactions and interactions with citizens, businesses, and other arms of government.

Shape the Future of Computing

ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.

Get Involved

Communications of the ACM (CACM) is now a fully Open Access publication.

By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
