What is Twitter?

May 10, 2009

twitterTwitter is a free social networking and micro-blogging service started by Jack Dorsey in 2006. It enables users to send and read other users’ updates known as tweets.

Tweets are text-based posts of up to 140 characters in length which are displayed on the user’s profile page and delivered to other users who have subscribed to them (known as followers). Senders can restrict delivery to those in their circle of friends or, by default, allow anybody to access them.

This video may explain it better:

Who uses Twitter?

The Los Angeles Fire Department used Twitter during the California wildfires in October 2007. NASA have used it to update the public on its various space missions. Barack Obama used it extensively during his campaign and celebrities are now using it such as Stephen Fry.

Unfortunately Twitter is blocked in schools by the NCTE but do visit the sgcbusiness.com Twitter page .

Google Street View

March 29, 2009

google-street-view-carIf you see a black car with the Google logo in Ireland in the next few months, give a wave. This is the Google car used to capture images for Google Maps’ Street View.

Street View is Google’s online, interactive, panoramic street level photographic mapping system that is part of Google Maps.

The street car is now in Ireland taking images of Irish streets in five cities: Dublin, Cork, Limerick , Galway and Waterford. Google hope to have these cities on Street View within the next few months.

Street View has received a lot of media attention recently in the UK due to concerns over privacy. According to Google, their technology blurs out both faces and registration plates and people can also report details on Street View that are inappropriate.

So how useful is Google Maps’ Street View?

Tourists can use it to check a city they intend visiting, auctioneers could use it to sell houses and businesses are already using Google Maps on their websites to show their location. We use Google Maps on our school website.

See what cities and towns are currently available in Street View.

Databases

March 19, 2009

DatabaseThe next exam for Mr. Hannon’s ECDL class is scheduled for Thursday April 2nd in the Computer Room. This exam is on Module 5 – Database.

As discussed in class today, a database is simply a file that stores information or data. We actually use databases every day on the web e.g., searching for the book you want on Amazon, looking for a used car on Carzone.  All businesses and organisations maintain a database of their employees and customers e.g., we have a database here in the school of all students.

You should divide Module 5 into four sections:

  1. Tables
  2. Forms
  3. Queries
  4. Reports

Use your CD and Syllabus as always to prepare for the exam and you should also look at the videos for Module 5 on Teach-ICT.com

Microsoft’s virtual storage centre

February 6, 2009

In Thursday’s ECDL class, we talked about “cloud computing“. In future, all our applications and files will be stored online. You are already using cloud computing by using your Google Apps account.

So how does cloud computing work? Here is an example of one of Microsoft’s large data centres which house all the servers to store our data.

In a very unremarkable looking building in Quincy, Washington State, is housed what has been dubbed ‘the belly of the internet’.

Inside there are 300,000 servers which make up Microsoft’s virtual storage centre that enable thousands of us to store the vast amounts of data that we all put online i.e. in the “cloud”.

Watch the following Youtube video of Microsoft’s data centre:
