Are you looking for a simple way to host and embed your PowerPoint slides on your own website or blog?

If you don’t like the advertisements on Slideshare & Co. and don’t need the additional features of these services, then Microsoft has a free and simple alternative for you! 

Here is what to do:

  1. Upload your presentation to your server
  2. Go to
  3. Paste the link to your PowerPoint file there and then click on “Create URL”
  4. Open the preview page, click on “File” and then on “Share”
    (Example: Preview for the above link)
  5. There you can grab the embed code for use in your blog or website
    (Example: Embedded version for the above link)

This also works with other office documents! Nice! Read more »

Today, we added a new component to our experiments withScratch logo.

7+ LEGO Education WeDo (product website)

  • 9580 LEGO® Education WeDo Construction Set
    150+ elements including a motor, motion and tilt sensors, and the LEGO USB Hub
  • 9585 LEGO® Education WeDo Resource Set
    extra building blocks for more models like Ferris Wheel, Crane, Car or House, additional elements such as wheels, rotors and a door

The distance sensor can sense objects within a range of about 20 cm in steps from 0-100. The tilt sensor can have five different states and the motor can be turned on/off, run with different speeds from 0-100, change direction and be on for (x) seconds.

This is what LEGO says are the key learning values:

  • Designing and making
  • Brainstorm to find creative alternative solutions
  • Learn to communicate, share ideas and work together

I can second that. It was so much fun to build the models together with my son (10) and to watch him learning, picking up some tips and improving his models.

From running Scratch on the computer, we already had a screen, speakers, mouse, keyboard and microphone. It is crazy what interesting and manifold combinations you can create when you add the motor, tilt and distance sensor.

For example just watch this girl explaining here Flying Bird or this boy explaining his space shuttle launch.

Here are some of the models we’ve built today:


Our helicopter accelerates when you lean it forward and it slows down when you tilt it back.
(You can discuss our model on Facebook.)


The kicker waits until sth. rolls in front of it’s distance sensor and then starts the motor to kick it away.
(You can discuss our model on Facebook.)

Sail boat

It was moving back and forth while a sound of bubbling water was playing in the background. 🙂

When Microsoft released first released the Office 365 Developer Site, with the preview of SharePoint 2013 in July 2013, I was impressed how easy and fast a developer was able to start developing for SharePoint 2013 and Office 2013.

With todays announcement of the availability of the Office Developer Tools for Visual Studio 2012 things change for the worse.

You now need to be:

  • MSDN subscriber
  • (Plan E1 or E3) Office 365 subscriber
  • pay $99.00 per year for a Office 365 developer subscription

This will unnecessarily slow down the development of Office and SharePoint apps.

Bad move!
