English messages account for only half of the messages on Twitter, a study of 2.8 million tweets has revealed. The analysis, carried out by Semiocast, showed that the top 5 languages used on Twitter are: English, Japanese, Portuguese, Malay and Spanish.
The study was conducted on messages gathered over a period of 48 hours, from February 8 to February 10, 2010 to establish Twitter’s most used language ranking. The messages were processed with Semiocast’s analysis tools which can identify the language used in short messages among 41 languages in all major writing systems (including Greek, Hebrew, Chinese, Korean, Tamil, Devanagari, …).
English is still the most used language on Twitter, with 50% of messages, reflecting its high penetration rate in English-speaking countries and the tendency of Twitter users that are non-native English speakers to tweet in English. This is nonetheless a sharp decline from the two-third share English was representing in the first half of 2009. In the near future, English’s share should drop even further as the strongest growth for Twitter is expected to come from non-English speaking countries.

Leading universities report that enrollment in computer science and engineering courses is up significantly this year among students pursuing computer science majors as well as those studying other subjects, particularly science or business.
"I think the job market is what's driving the growth," says Professor Bruce Porter, Chair of the Department of Computer Sciences at the University of Texas at Austin, which has seen its enrollment increase more than 5% this year. "The government has made it clear that computer science is a growth field, and I think that message is getting back to students and their parents."

"A respected Swiss scientist, Conrad Gessner, might have been the first to raise the alarm about the effects of information overload. In a landmark book, he described how the modern world overwhelmed people with data and that this overabundance was both "confusing and harmful" to the mind. The media now echo his concerns with reports on the unprecedented risks of living in an "always on" digital environment. It's worth noting that Gessner, for his part, never once used e-mail and was completely ignorant about computers. That's not because he was a technophobe but because he died in 1565. His warnings referred to the seemingly unmanageable flood of information unleashed by the printing press.
Worries about information overload are as old as information itself, with each generation reimagining the dangerous impacts of technology on mind and brain. From a historical perspective, what strikes home is not the evolution of these social concerns, but their similarity from one century to the next, to the point where they arrive anew with little having changed except the label. .."

"You probably have an attic, closet or garage stuffed with unused, outdated tech junk. Wouldn't you like to do something useful with them? These are some good and some goofy ideas for DIY projects."

When Scholars Weigh Publication Options, Tradition Counts
By Jennifer Howard
Although more and more scholars are interested in trying out new technologies as a way to share or publish their research, the traditional cultures of their disciplines and the high regard accorded to peer review still tend to have the strongest influence on them, according to a substantial new report on scholarly communication from the Center for Studies in Higher Education at the University of California at Berkeley.
The report, "Assessing the Future Landscape of Scholarly Communication: An Exploration of Faculty Values and Needs in Seven Disciplines," focuses in depth on the fields of archaeology, astrophysics, biology, economics, history, music, and political science. Produced with the help of a grant from the Andrew W. Mellon Foundation, the report draws conclusions from interviews conducted over several years with 160 scholars from 45 "mostly elite" research institutions.
Although the seven fields surveyed have very different cultures, which are explored at length in the 733-page report, the executive summary points to the persistence of doing scholarly business as usual. "Experiments in new genres of scholarship and dissemination are occurring in every field, but they are taking place within the context of relatively conservative value and reward systems that have the practice of peer review at their core," the report states. It found that young scholars "can be particularly conservative" in their behavior, perhaps because they have more to lose than senior scholars, who "can afford to be the most innovative with regard to dissemination practices."
If that's the case, younger scholars may just be heeding advice to play it safe.
