The Mom Song (William Tell Overture)

This is a good video to play for 8am classes while you are waiting for class to start. The William Tell Overture is very difficult to sleep through, IM through, etc. And Generation Y students can usually relate to this video as the comedienne does remind them of their mom!

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.

Pictures Not to Include on a Blog or a MySpace Page

I'm always amazed at the pictures that students will put on blogs or social networking sites. They may be great photos to share with your friends, but if you are identified in the photo, is it worth jeopardizing your chances of being selected for a job? Just in case you need some guidelines about what not to include on your site, here are a couple of suggestions...

You may feel passionately about a particular cause...which is fantastic...get involved! However, a prospective employer may not agree with your views. In the majority of cases, you should keep your personal views separate from your work life.


Anything showing you with alcohol, partially clothed or in an embarrassing situation. It might have been a great party, but will it impress an employer?


It is hard to imagine how the ability to do a keg stand would impress any boss! Yet I constantly see these photos on the web.


Discussion Questions for Students:
1. Have you ever posted anything online that feel that a potential employer should not see? Do you think it would affect you landing employment?
2. Should employers check the Internet for information before hiring potential employees? Why or why not?
3. Do you think that you should have a right to privacy regarding information you place on a MySpace or Facebook page? How would you ensure that your privacy was protected?
