Pervasive Computing

Posted: October 25th, 2003 | No Comments »

Pervasive computing envisions giving you the services you want—when, where, and how you want them. We expect these services to be invisible, interoperable, proactive, mobile, intelligent, and secure in heterogeneous and mobile environments. It encompasses many areas of computer science, I have been interested (and did some work on) lately, including distributed systems(SEC, Negotiator, Borland), mobile computing (upcoming projects at the CRAFT), mobile agents (Negotiator), and intelligent systems (Negotiator).

Pervasive computing is the future of computing by the instructor of this IEEE distributed system course (Pervasive Computing Education).

Make your code more maintainable by avoiding accessors

Posted: October 24th, 2003 | No Comments »

Why writting accessor methods should not become a religion? Even thoug arguables (you always can say in depends on the context) Allen Holub makes good remarks in Why getter and setter methods are evil.

The lack of getter/setter methods doesn’t mean that some data doesn’t flow through the system. Nonetheless, it’s best to minimize data movement as much as possible. My experience is that maintainability is inversely proportionate to the amount of data that moves between objects. Though you might not see how yet, you can actually eliminate most of this data movement.

From the Scout Report:
Drawing on information collected during the 2000 Census, this latest brief from the Census Bureau looks on language use and English-speaking ability across the US [PDF]. Authored by Hyon B. Shin and Rosalind Bruno, this 11-page report begins with a brief discussion of the questions asked about language use on the 2000 Census reporting form. The initial findings include the fact that approximately 47-million persons in the U.S. (approximately 18 percent of the total population) speak a language other than English at home. Not surprisingly, the number and percentage of people in the U.S. who spoke a language other than English at home increased between 1990 and 2000. Additionally, after English and Spanish, the languages most frequently spoken at home were Chinese, French, German, and Tagalog. The report also includes several helpful maps that detail (at the county level) the percentage of people who spoke a language at home other than English in 2000. [KMG]

I love spam’s latest evolution. It keeps my brain thinking and wondering (from that point of view it is art, isn’t it?). While my eyes stopped getting caught by the nevertheless beautifull work the pioneers like the nigerian connection (I sense a shortage in imagination lately), I am fascinated by this one:
