Guy Kawasaki, has written a nice article concerned with the art of creating a decent powerpoint presentation…How to Change the World: The 10/20/30 Rule of PowerPoint. His article is written with the business community in mind however I feel his 10/20/30 rule is just as applicable to educators as well.

Hi all

A friend “burnt” an audio CD and when it is placed in different devices its volume name as well as the single audio file name included on the audio CD changes. Here is his description of the problem…

1. Audio recording made on iBook #1
2. File burnt to CD on iBook #1. Name of CD is “Audio CD”
3. CD tested on iMac desktop computer and volume name appears as Paris which is the name of a previous disc burnt on the iMac.
4. Same CD tested on iBook #1 volume appears as Jo Logan -the name of the previous burn on iBook #1.
5. CD tested on MacBook Pro appears as “Audio CD”.
6. On each occasion the recording plays as recorded but volume and file names change.

Has anyone seen this problem before?

A colleague, Alan, shared this amazing piece of software with me today. It is called Jing Project. It captures video or stills from your computer’s screen. It is cross-platform ~ Win or Mac. The team has a blog as well.

I was in the Cave at school today and chanced upon my colleague Rick who was in a video chat with Jeff at St John’s. Jeff was making inquiries about downloading video from YouTube. You know, have you ever chanced upon a video hosted on YouTube or even TeacherTube that you thould would be useful as an icebreaker for a lesson or an excellent example of a scientific principle? Then you wish to download it for later use? Well, here are two solutions:

1. A quick search on Google unearthed TubeSock. A nice piece of software. It is not free but it is excellent.

My friend Siva from Singapore entered the iChat conversation and I shared with him our dilemma and he fired this suggestion at me:

2. Firefox browser add-on: Video Downloader 1.1.1.

3. As above, alternative URL for Video Downloader 1.1.1.

Enjoy!
