One year of Google WiFi in Mountain View, CA

The official Google Blog reports on the first year anniversary of the free available WiFi Network in Mountain View, CA the home of Google. The 400+ mesh routers are being used by 15.000 unique users every month that use roughly 300GB each day of network traffic.

Sine I am living in San Francisco I hope that the effort of Google and Earthlink will bring the free WiFi access to the city. To push this initiative forward people living in San Francisco can contact the Board of Supervisors.

Meraki is another project that tried to encourage existing WiFi network owners to open up their network for others. You can sign up and plug in a so called Meraki repeater that configures itself to extend the freely available network. Meraki is backed by Google and Sequoia Capital and has been initially a Ph.D. research project at MIT.

European E-Communications household survey

The results of a special Eurobarometer survey conducted by TNS Opinion & Social between 17 November 2006 and 19 December 2006 to measure the attitude of European households and individuals towards fixed and mobile telephony, Internet access, TV broadcast services, bundled offers, 112 emergency call number, telephone directories, privacy and security. The survey covers the 27 EU Member States together with Candidate countries (Croatia and Turkey) and the Turkish Cypriot Community, with an average of 1.000 households interviewed per country.

Some of the key findings for the European Union are (taken from the E-Communications Household Survey):

  • On average, most European households have both fixed and mobile telephone access (EU27: 58%, EU25: 60%).
  • The level of use of mobile phones remains fairly stable (81% in EU27) while at the same time more and more households give up their fixed line.
  • For many households, the reason for keeping their fixed line is still the internet connection (22%).
  • The majority of European households (54% in EU27) have a computer, primarily a desktop computer (36%). 34% of EU27 households with internet access at home have a wifi router.
  • Most households access internet via an ADSL line (EU27: 53% of households with broadband access, EU25: 54%).
  • Over a quarter of households with internet access have suffered from significant problems caused by spam, viruses and spy ware. The main consequence appears to be a lowering in the functioning of the computer (40%) or even a breakdown (27%).
  • The use of service packages has increased slightly (EU27/EU25: 20%, +3 points), the most common combination being fixed telephony and internet access. Respondents are particularly satisfied with the fact that two services are invoiced at once and that the combined price is cheaper than that of two separate services.

One question easily answered: What are you doing?

Twitter LogoAfter a lot of things have been written about Twitter and it’s community that answers only one simple question: “What are you doing?” I checked this “… social networking and micro-blogging service“, that even has an entry at Wikipedia already, out. I have to admit that I have checked Twitter out a little while ago and was wondering what makes people interested in continuously post what they are doing right now. For example, are you interested who is having lunch right now. No problem. A visit at Twitterment, a Twitter search service, will reveal who is lunching right now (Source: Binaryplex.com ,Library Clips).  Okay, now the question remains what are people doing right now and where geographically wise are they doing it? The answer is out there and Twittervision.com is a pretty neat mash-up application developed by David Troy that will show what is going on in real time at the Twitter community.
Alright, and for those of you who want to ban Twitter to their Apple Macintosh computer their is the free software application Twitterrific out there (Source: Twitter Blog). If you know of a similar application for Microsoft please add a comment to this post and let other readers know about it.

What makes Twitter so popular? I think it is very simple, we are always interested in what our friends are doing. A lot of times it is “… the first thing we ask when we call someone” (Source: Read/WriteWeb).  A little snipped of text provides us with the real time information and a simple social need id fulfilled.

However, I have not decided yet for myself if I am going to use Twitter to keep my friends and readers up to date with my activities. If so you probably will see it on this blog in one of the sidebars.

Unlimited online storage space, interested?

John Kremer, the vice president of Yahoo, announced at the end of last month that Yahoo Mail is lifting the limit of their inbox storage space. Wow, I remember quiet well that I did search for unlimited storage space for backup copies of presentations, manuscripts, photos and the occasional music file. Right now they are scattered all over the place.

However,  Asher Moses wrote in The Age an announcement about this and refers to comScore Media Metrix stating that Gmail “… has 51 million users worldwide, [and] offers 2.8GB of space; Microsoft’s Windows Live Mail offers 2 GB and has 228 million users.” What I personally didn’t know so far is, that Yahoo is the leader with 250 million users of their mail service. Which makes sense, since they have been around the longest, for 10 years to be precise.

The question remains, how long it takes for Gmail and Window’s Live Mail to catch up or offer features that convince users to use their services over the one from Yahoo Mail?

TEDTalks – Hans Rosling

Did you ever wonder how to visualize your data that people understand and grasp the information easily? One man who really understands how to do that in the field of international health is professor Hans Rosling from the Swedish Karolinska Institute, who also is the “… founder of Gapminder, a non-profit that brings vital global data to life“. He gave a presentation in February 2006 at Monterey, California at TEDTalks and gave a quiet stunning example of his outstanding work and how to visualize data . To see a recording of his presentation click here. I highly recommend visit the Gapminder tool at the Google website since it “… makes it possible to search deep into Gapminder’s moving graphs visualizing world development“.

The question remains is there any tool or WebApp out there that helps you to visualize, display, share and discuss your data. Actually there is and it is called Many Eyes. I only briefly explored this tool which seems to be pretty comprehensive but easy to use. Any kind of feedback is greatly appreciated.

Last but not least there are a couple of books out there on how to visualize data. A name to mentioned in this regard is the one of Edward Tufte. Here is a list of his books at Amazon. I once went to a seminar here in San Francisco he gave and wasn’t impressed and left after lunch. However, is books are definitely worth to have a look at.

TEDTalks – Jeff Han

TEDTalks are presentations about Technology Entertainment Design. One of these presentations about an “intuitive, interface-free, touch-driven computer screen” I cam across via Jochen Robes Weiterbildungsblog (German for continuing education blog). I encourage you to go and check out this 10 minute video presentation that has been recorded on February of 2006. It really is amazing to see what might be the interface we will use to interact with computers in the future.

Jeff Han is a research scientist for New York University’s Courant Institute of Mathematical Sciences. Here, he demonstrates—for the first time publicly—his intuitive, “interface-free,” touch-driven computer screen, which can be manipulated intuitively with the fingertips, and responds to varying levels of pressure.

More Trends and Predictions

I know, I know, there are a lot of trends and predictions being published and released right now. After all it is this time of the year to reflect on what happened and to predict what might be.

However, I just received the wwwtools for education newsletter with a nice assembly of “Trends from 2006, Projections for 2007… and Beyond“. Graeme Daniel put a nice list of notes and trends in education together. He split these different areas up into the following categories:

  • Highlights: Technology in education, 2006,
  • Technology 2006,
  • Forecast for Technology, 2007,
  • At the hardware trade shows,
  • The iPhone – Rising Star of Macworld?
  • More mobile and wireless trends,
  • Converging technologies: Computers, TV, Video and Net,
  • A mixed bag (e.g. Web 2.0, Nanotechnology),
  • Just for fun, and
  • Books.

Enjoy once again the trends of 2006 and predictions for 2007. If you want to sign up for the wwwtools for education newsletter you can do so by clicking here.

Missuse of Youtube

When I went to school cell phones and other electronic devices didn’t exist in the classroom. Well, maybe a TV was mounted on the wall to watch some educational programing.
Today things look quiet different, especially when it comes to the way of using new technology to let everybody else know what is going on inside the classroom. The New York Times published a story (registration required; free) about two teenage students who willingly aggravated one of their teachers. The incidence has been recorded and the footage went online at Youtube. The 33 year old teacher is on voluntary sick leave who taught students with a learning disabilities.
The video has been removed from Youtube upon request from the Portages-de-l’Outaouais school board and the two students have been suspended from the school.
