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!")

Increase Your Blog or Web Site Functionality with Mashups

Web 2.0 is all about functionality and user input. There certainly is plenty of data available on the Web, but sometimes it isn't exactly in the format you desire. This is why mashups were born. A mashup draws data (or functionality) from two (or more) different sources and deploys them within a single tool. An example would be drawing location pictures from Google Earth and adding them to house listings from a real estate agency. Lots of mashups are created using Ajax (Asynchronous JavaScript and XML) methodology.

But for mere mortals, like your computer literacy students, Microsoft has provided a site which allows the easy creation of mashups with drag and drop functionality. Popfly is a cool site which you can access for free using a Microsoft Live ID (also available for free). Once you are there, there is a handy tutorial which will have you making your first mashup, which you can then deploy on a blog, social networking site or Web page, in just minutes. But to make things even easier, just watch the video below which shows you how to make a photo carousel mashup and include it on a blog.



So turn your students loose on Popfly and see what they can create. If you are using blogs in your classes (see the Blogging Across the Curriculum blog) or have students creating their own social network on Ning, require them to make a mashup and include it on their site. You may be surprised at what they design!

Sources of Videos Other Than YouTube

Can't find what you are looking for on YouTube? There are certainly plenty of other sources of free video on the Internet. Here are a few of my favorite sites:

Google Video - You would think since Google bought YouTube they would have combined the two sites by now (or at least made the functionality the same). But you would be wrong! Google Video, still technically in beta, hosts videos in a similar fashion to YouTube. But the real strength of this site is the search feature. As you can see from the image below, the search box default option is to search the entire web for videos, not just ones hosted on the Google Video site. Therefore, this is a superior search feature to the one offered on YouTube which only searches videos hosted on the YouTube site.



Lab Rats - Two technology journalists, Andy Walker and Sean Carruthers, started making video podcasts in October 2005. Fortunately for us, people loved them and now the Lab Rats website contains over 100 video podcasts on technology. These videos are well written, produced professionally and contain useful information on topics ranging from Web browser security to iPod hacking. There is something here for every level of student.

5 min - 5min is a site that offers short video solutions (all 5 minutes or less) to practical questions. Their idea, as explained on their site, is simple: "...any solution can be visually explained in no more than 5 minutes. Our goal is to create the first communal Life Videopedia allowing users from all over the globe to contribute their knowledge by sharing visual guides in areas such as arts, business, fashion, sports, health, tech, food, and much more." They have a technology section which contains some very informative videos such as Wikis in Plain English and How to Retrieve a Lost Windows Password. While not as extensive a collection as YouTube, the videos at 5min are very high quality and well produced videos.

If you know of any other sites that provide useful technology videos (for free, of course), mention them in a comment to this post and I'll add them to this list.

A Vision of Students Today

This video gem is from the Cultural Anthropology Faculty at Kansas State University who have brought us so many other clever videos over the past couple of years. They asked their students to work on a shared document (sort of a wiki) and to comment on what was going on in with each of them when they were in the classroom. They filmed the results and displayed them in a thought provoking way (students holding up signs). The students' comments probably reflect many of the issues your students are facing.

Even though this video is designed more for faculty than for students, I still find it beneficial to show to my students. It gets them thinking and often sparks a good discussion about what they want to get out of my class. Often showing this video will spark student interest in using Wikis. Two free sites where students can set up Wikis are wikispaces and pbwiki.



Discussion Questions for Students:
1) Which issues from the video are you facing in your classes? What solutions would you propose to the students in the video to address their concerns?
2) Have you ever used a Wiki or Google documents to share information with a group or plan a project? Have you ever used these tools in classes at this institution?
3) Do you think you would find Wikis useful in your classwork? What about in your personal life?

How Not to Use PowerPoint

This is a humorous look at things you shouldn't do when you are creating PowerPoint slides to support a presentation. Even though it is funny, the video makes a lot of valid points that are worth pointing out to students.

Fun With Hard Drives

Hard drives need to remain hermetically sealed otherwise they tend to stop functioning. But have you ever wondered what a hard drive looks like on the inside while it is running? Thanks to someone sacrificing a hard drive (they won't be able to use it again), now you can see what really happens.



And if you've never defragmented a hard drive, this is what it looks like in time lapse mode.

Would You Like a Little Cholesterol Medication with That Pizza?

Many people are concerned that technology and the Internet are eroding our personal privacy. The video below is the ACLU's slant on what it might be like to order a pizza in the near future. Fasten your seat belts...its going to be a bumpy ride!



Now we all hope that this level of scrutiny doesn't happen but my local pizza parlor already tracks orders by phone number. So when I call they usually have a pretty good guess about what I'm going to order. At least they don't have access to my medical records, library records and magazine subscription information...yet. But with all this information in databases, it is theoretically possible to consolidate it all at the pizza parlor.

Fortunately, the privacy of medical records is protected by law. But say the local pizza parlor did run a coupon in Men's Health magazine. They could buy the list of local subscribers from the magazine and integrate it into their database that is keyed off of caller ID. Then they would be able to mention the coupon to callers who subscribed to Men's Health. It presents interesting possibilities.

Discussion Questions for Students:
1) What types of personal information would you feel comfortable with a merchant (like a pizza parlor) having about you? What types of information would you never want revealed to retailers?
2) What is your position on a national ID card (or the REAL ID)? Is preventing terrorism worth giving up some personal privacy rights?
3) Should personal medical information be more readily available if it could be used to protect your health? Would you feel comfortable with a server at a restaurant recommending healthy food choices based on your medical history?

Building Your Own Computer

It sure is easy to drive down to Best Buy or Costco and buy a computer. But there is something satisfying about building your own computer and configuring it exactly the way you want it. Some students might consider this a daunting task and would never attempt it. Watching the video below will give you a rough idea of what is involved in assembling a computer.



Now I wouldn't suggest running out to build a computer after just watching this video. You probably should do some more research first. Naturally, How Stuff Works has a section on How To Build a Computer. PC Mech has a Build Your Own PC section that gives step by step instructions with over one hour of video.

Although most of you won't build a computer from scratch, you may need to upgrade some components of your computer. For instance, you may need to upgrade your RAM to get the best performance out of Windows Vista. Or maybe you are craving a new Blu-ray drive for your desktop computer. You can find plenty of videos on YouTube that show you how to upgrade your computer like the one below on how to install RAM.



There are numerous online merchants where you can buy the parts to assemble your computer. Two of my favorite spots are New Egg and TigerDirect. I have friends who have had excellent experiences with New Egg and I have been very satisfied with my purchases from TigerDirect. And Crucial is a fantastic web site for purchasing RAM (as mentioned in the video) which I have used numerous times.

Discussion Questions for Students:
1) Have you ever built, modified or upgraded a computer? If so, how successful were you? (i.e. did the computer work when you got done?)
2) Would you ever consider building your own computer from scratch? What would be the advantages and disadvantages of doing this?
3) If you had problems building or upgrading your computer, who would you consult for help? Does the Geek Squad (at Best Buy) help with assembling computers (they do perform upgrades)?

Memory Problems (And I Don't Mean RAM!)

Perhaps you know someone that has a few problems like Tom Rush describes in this cute little tune.



I show this video on the first day of class. It serves as a great conversation starter because it is always easy to get students talking about themselves (see questions below).

Discussion Questions for Students:
1) What devices and software do you use to keep track of events happening in your personal life?
2) What suggestions would you have for the poor fellow in this video to help him start remembering the important events in his life?
3) Have you ever instructed a parent (or grandparent) on using some type of technology? Were there any challenging issues you encountered during this "training"?

Securing a Wireless Network

Home wireless networks are more susceptible to bandwidth poaching than wired networks because the signal often reaches outside of your home. This makes it easier for hackers or war drivers (people who locate and connect to unsecured wireless networks) to sit outside your home and connect to your network. Your neighbor might be accidentally connecting to your network instead of his own and thereby using some of your valuable bandwidth. Or if you happen to live next door to an unethical person, they might cancel their own Internet account and deliberately connect to yours to save money!

To avoid these scenarios, you should implement security measures on your wireless network. The video below from the Get Connected TV show shows you some simple measures to take to protect your wireless network from unwanted "guests".



Discussion Questions for Students:
1) Have you ever logged onto a wireless network without the owner's permission (such as a neighbor)? Do you think there is anything unethical about "sharing" bandwidth with your neighbor (at their expense)?
2) If you have a wireless network at home have you implemented security measures such as the ones mentioned in the video or listed on the Practically Networked web site?
3) Do you have a firewall installed on your network? Is it turned on? Do you know what a firewall does and why you should have one? If not, find out at the firewall section of How Stuff Works!
4) Have you tested your network to see if it is secure? If not, try the ShieldsUP test at Gibson Research. What were the results? If your network is not secure, what could you do to make it more secure?

Extending Your Wireless Range & Finding Free Wireless

Many of you have probably experienced the frustration of being out of range of a wireless signal when you need one. Even though hot spots are growing at a rapid pace, you aren't always within range of one that you can log onto for free.

In the video below, Mark Erickson who creates video podcasts called Infinite Solutions, shows you a hack to extend the range of your wireless card. Although it is disappointing that he didn't put the tin foil dish on his head, this is still an interesting solution.



And here's a video on a software product called WiFi Radar that helps you easily detect wireless networks that are within range and the software also sees if it can log you into the networks that it detects.



However, you should exercise extreme caution when searching for wireless networks. Just because you can detect a network and log onto it, doesn't mean that you are legally entitled to do so. You could be guilty of violating "piggybacking" laws. Piggybacking is using someone's bandwidth without their permission. So I recommend sticking to hot spots that are free where merchants are encouraging you to log on (such as Panera Bread). Web sites like WiFinder can help you locate hot spots that you may access legally.

Discussion Questions for Students:
1) Have you ever logged onto a wireless network without the owner's permission (such as a neighbor)? What do you think the implications would be if you get caught engaging in this type of activity?
2) Is it illegal where you live to "piggyback" on a wireless signal? Do you feel it should be illegal to connect to an unsecured wireless network even without the owner's permission?
3) Where can you go locally to legally connect to a wireless network and get free Internet access? What types of benefits do merchants like Panera Bread derive from providing free wireless access to their customers?
4) If you aren't a customer of Panera Bread, do you think it is fair to sit outside in your car and connect to their wireless network?

PCs Made From Corn?

Disposing of e-waste from computers and other electronics is rapidly becoming a worldwide problem. Many parts of computers, especially the plastic components, are not readily biodegradable. Environmentally conscious manufacturers, such as Fujitsu, are exploring renewable resource options for computer components.

At the CES 2008 trade show Fujitsi unveiled a notebook computer with a case made of a corn-based polymer as instead of the usual plastics derived from petroleum products. Fujitsu states that the main component of the case is "polylactic acid, also known as PLA, a resin that comes from the fermentation of the raw biomass from plants. PLA by itself is biodegradable, does not generate dioxin when burnt, or other harmful gases." The video below discusses the notebook.



Discussion Questions for Students:
1) Have you ever bought a computer or electronic device because it was manufactured in an environmentally friendly fashion? How important was this in your purchase decision?
2) Do you know what environmentally hazardous substances are contained in your current computer? Are any of these present: Lead, mercury, cadmium and brominated flame retardants? Why do these substances pose hazards?
3) Where can you go locally to ensure that your discarded electronic equipment is properly disposed of or recycled? What questions should you ask before handing over your equipment?

You can find plenty of information on the EPA's site.

Think Before You Post!

Discussing the dangers of posting too much personal information online with our students often comes off sounding like a lecture from a parent. But these two public service ads produced by the National Center for Missing and Exploited Children usually get a strong reaction from students. They creep me out every time I watch them too!





The accompanying Think Before You Post Web site has some great tips for keeping yourself safe when communicating online.

Discussion Questions for Students:
1. Have you ever posted anything online that you later regretted posting? How has it affected your life?
2. What steps do you take to keep your personal information from becoming available online?
3. Do you have a MySpace or Facebook page or do you post personal information on a similar site? Have you availed yourself of the options available on these sites to keep your information from being indexed or otherwise published online?

Create a Web Site - Find a New Career

Over the years, plenty of people have thought that just knowing a little bit of HTML coding qualified them to be Web site designers. But for Linda Katz of southwest Kansas, practicing her Web design skills helped her launch an entirely new career -- as a tumbleweed farmer!

The Prairie Tumbleweed Farm started out as a simple Web design exercise. Linda wanted to practice her skills and created the farm as a joke back in 1994. But, people found her site and soon began contacting her because they wanted to buy the tumbleweeds! One thing led to another, and Linda now has a thriving business. Her customers include NASA, major Hollywood studios, fashion designers, and ordinary people who just want to own one of these iconic symbols of the old West.

Linda was recently featured on Yahoo!'s People of the Web and she has an interview posted on YouTube, which you can view by clicking the link below:



Discussion Questions for Students
1. Do you personally know anyone who is running a successful Internet business? Do you know how they got started?
2. Have you ever considered creating your own online business? What type of product or service would you offer?
3. Hands-on Exercise: Ask students to find a YouTube video featuring an interview with an entrepreneur who operates an online business.
