What is ECDL?

The European Computer Driving Licence (ECDL) is the world’s most successful IT skills certification programme. Almost three million people are participating in the programme today in over 60 countries worldwide. Over 125,000 secondary school students in Ireland have completed the ECDL.

In Ireland, the ECDL is administered by ICS SKILLS.

The ECDL establishes a standard for everyone who uses a computer in either a professional or personal capacity. It is a certificate that verifies competence in computer use, making the holder readily mobile within Ireland and internationally. Employers and job seekers all agree on the importance of this standard definition of practical competence in Information Technology.

The ECDL consists of 3 main components – a syllabus, a skills card and a question test base, all leading to the European Computer Driving Licence.

If you have any questions on ECDL, post them in the comments sections of this post or you can email mrhannon [at] geralds [dot] ie

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 Twitter page .
