Windows Server 2008 Robot

Microsoft is billing Windows Server 2008 as "The Server Unleashed" and has created a cool Web site featuring a nice CGI robot. When you click on the different features of the OS, the robot takes slightly different poses. Aside from being amused by the robot, you can also download a trial copy of the software to evaluate it. And don't forget to grab some images for your Windows wallpaper from the Toy Box like the one below!

Recycling Technology - Dispose of Broken Computing Devices Responsibly

Here's a catchy little tune called the Dead iPod song. It describes what to do with your iPod when it inevitably dies.



Many companies now have recycling programs. Apple has an iPod and cell phone recycling program which provides you with a free (they pay the postage) way to send in your broken iPods and cell phones for environmentally responsible disposal. Dell's recycling program always provides free recycling for Dell branded products. And if you buy a new Dell system and select free recycling at the time of purchase, Dell will even recycle your old computer and monitor for free even if it isn't a Dell product.

Discussion Questions for Students:
1) Do you have any broken computing devices at home? How are you planning on disposing of them?
2) Have you ever thrown an old computing device in the regular trash? What impact do you think this had on the environment?
3) HANDS-ON ACTIVITY: Search the Web for technology recycling programs in your area that accept old computers and monitors. Are there limitations on what types of devices they accept? Is there a charge to the consumer for recycling?

Bluetooth Security Problems and Solutions

As most of our students have cell phones, many of them also have Bluetooth devices such as wireless headsets. However, most people don’t realize that Bluetooth transmissions are not a secure technology. In this video, Joshua Wright (an instructor at the SANS Institute) shows us how easy it is to listen in on a Bluetooth device and even inject your own audio into the device you’ve compromised.



Although requiring technical skills beyond the casual computer user (as it involves using Linux and other seemingly arcane protocols), a computer science student would probably have no trouble in replicating these actions. In fact there are many web sites that list Bluetooth hacking tools with links to download them. Fortunately there are simple ways to protect yourself from Bluetooth snooping and one of the best resources for Bluetooth protection is on the Bluetooth site itself. Following these guidelines should help your students (and you!) stay more secure when using Bluetooth enabled devices.

Discussion Questions for Students:
1) What types of Bluetooth devices do you use on a regular basis? Have you configured them (after pairing them with your devices) into a non-discoverable state so that other Bluetooth devices can’t find them?
2) Have you updated the firmware (for that matter, what is firmware?) in your Bluetooth devices lately? Do you know how to do this? Do you know why it is important to do this?
3) Do you have antivirus software installed on your phone or PDA? Do you keep it updated on a regular basis?

Using Wikis in the Classroom

Before you can launch students on a group project involving wikis, you obviously need to explain what wikis are and their basic functionality. Students can get a quick grasp of the basics of wikis by watching this video:



And, a good article from Information Week explains How to Use Wikis for Business. If you have students watch the video and read this article before class, you can get them up to speed on the idea of wikis pretty quickly.

Naturally, the students will need a free wiki site to use for any wiki project you assign. Two of my favorites are wikispaces and pbwiki. They are both very straight forward and easy to use.

Wikis are obviously great for group projects because of their collaborative aspects. Here are a few approaches you could take:

1) Student Study Guide - Have the students create and edit pages that provide a study guide for each chapter (or topic) you cover in class. This requires explaining concepts in their own words which reinforces learning. And this type of wiki can act as a repository of knowledge that next semester's students could update and expand.
2) Wiki moderator - Have a student create and moderate a page (that other students update) for a week. The page should cover one topic from the current course content and aim to provide a comprehensive summary of the topic.
3) Battling Business Units (with apologies to Dilbert) - Have competing groups create wiki pages on the same topic. Then assign one group each week to review all the pages on that topic and combine them into one comprehensive (definitive?) resource.

And if you need some inspiration for projects or additional insight for students, check out the wiki resources below.

Download Video From YouTube

Nothing is worse than having a great video from YouTube identified to start a class discussion and then finding out your network connection is down. You can avoid this unpleasant experience by installing a free product called YouTube Downloader from Biennesoft.

This freeware (no cost to use it) enables the downloading of videos from YouTube (and other sites) and saving them to FLV (Flash video) files. Now FLV files are bloody useless since it is difficult to find players to play them back. But fortunately the program allows you to convert the FLV files to more useful formats for display on devices such as iPods, iPhones, PSPs, Cell Phones, and Windows Media Player. You can even just export the sound to an MP3 file.

The software is dead simple to use. Just paste in the URL of the video and click OK to save it as an FLV file.



To covert to another format, browse to where the FLV file was stored and select it. Then choose the appropriate conversion format and click OK to convert. It couldn't be easier!



By downloading the video and converting it into an appropriate format you won't have to worry about losing your Internet connection. This also makes it handy for distributing the file via e-mail or in a course management system.

Web 2.0 Parody Video

Here's an amusing send up of Web 2.0 called Here Comes Another Bubble. It can be used to start a discussion of Web 2.0 in your classroom. WARNING: The darn song might run through your head all day!



Discussion Questions for Students:
1) What is Web 2.0? What are the key attributes of Web 2.0 applications?
2) Which of these Web applications do you use on a regular basis? Social networks (MySpace, Facebook, etc.) wikis (wikispaces, pbwiki, Google Docs), blogs, social bookmarking (digg, del.icio.us). Which sites are most useful to you and why?
3) What types of activities can't you do in the applications you are using now that you would do if the functionality were available? (This usually produces lively discussion as students say, "Hey, you can do this on blahblahblah.com!")

Building How-To Videos - For Free!

One of the best ways to learn a subject or to demonstrate mastery of a topic is to teach it to someone else. So why not assign student projects that require making videos that explain the functionality of Microsoft Office, a Web site or another application software package. And then the students can deploy the videos they create on YouTube and share their knowledge with the entire world. Now that is Web 2.0 learning in action! But since many colleges don't have a tool deployed for the students to use, a free tool for recording on-screen activity is needed.

Fortunately, CamStudio is an open source software package that is based on the widely popular (and expensive) Camtasia Studio product from Techsmith. The software is easy to install and learn to use. They even provide a handy video on downloading CamStudio. The help files in the product will get you familiar with how to use it. The recorder has simple basic functionality similar to older versions of Camtasia Studio.



This is not as fully-functional as the current version of Camtasia Studio, but the basic functionality is similar. For pure ease of use, Camtasia Studio 5 does offer significant advantages, but saving the students $299 is a big bonus for CamStudio. So have the students download CamStudio and get them creating their first videos this week!
