Promoting Science and Critical Thinking
The TED (Technology Entertainment and Design) conference is all about disseminating “ideas worth spreading.” and so every year since about 1990, the once-only 1984 conference has been happening every year. Ah, so its just another techi conference? Nope not at all, this is something truly special. The ticket price is $6,000 and even to attend … Read more
Bill Davidow, a high-technology industry executive and a venture investor, has written an Opinion piece in todays “Christian Science Monitor”. In it he suggests that the Internet will change our physical space in quite a dramatic way … Today, an even bigger change is afoot. The Internet is about to change our physical space. And … Read more
A study appearing Feb. 10 in Science Express calculates the world’s total technological capacity to store, communicate and compute information, part of a Special Online Collection: Dealing with Data. The study by the USC Annenberg School for Communication & Journalism estimates that in 2007, humankind was able to store 2.9 × 1020 optimally compressed bytes, communicate … Read more
So I followed some links and did a bit of reading, and as a result made a rather surprising discovery – Edison did not invent the light bulb – well perhaps you knew, and I’m the only one. After being surprised like this, I did a quick straw poll asking “Who invented the light bulk?”. The answer from all was, “Edison”.
Now what really surprised me is that while he did not invent it, he claimed that he did, but if it was not him, then who?. It was apparently a chap called Joseph Swan.
The just-released February issue of the Journal of the Society for Information Display contains the first-ever critical review of current and future prospects for electronic paper functions – in other words reviewing and critiquing the technologies that will bring us devices like
The University of Cincinnati’s Jason Heikenfeld, associate professor of electrical and computer engineering and an internationally recognized researcher in the field of electrofluidics, is the lead author on the paper titled “A Critical Review of the Present and Future Prospects for Electronic Paper.” Others contributing to the article are industry researcher Paul Drzaic of Drzaic Consulting Services; research scientist Jong-Souk (John) Yeo of Hewlett-Packard’s Imaging and Printing Group; and research scientist Tim Koch, who currently manages Hewlett-Packard’s effort to develop flexible electronics.

This Year
Already in use but expansive adoption and breakthoughs imminent:
Every available Internet protocol address has now been spoken for—which could mean huge trouble down the line.
…
The problem is that the current system for IP addresses, IPv4, uses numeric addresses that are 32 bits long—giving a total of just over four billion potential numbers, which must have seemed like a lot when IPv4 was introduced in 1981. But there are now seven billion people on Earth, and more and more of them—and their devices—are going online all the time. Fortunately, engineers realized the limitations of IPv4 a long time ago and lined up a successor, called IPv6, in 1998.
…
For ISPs, it’s a straightforward business dilemma: the two addressing schemes are not directly compatible, which means it would take a significant investment to let IPv4 users connect to IPv6 services. And having relied on the same system for as long as 30 years, they may not feel the need to change.
