Technical problems have led Princeton University to ban some iPad tablets from its network.

Technical problems have led Princeton University to ban some iPad tablets from its network.

If you're keeping score, here's the current tally: Israel has banned the iPad. Norway's prime minister thinks it's "excellent." Reviewers gushed about the new device. And now we hear that the IT team at Princeton University is shaking its fists at Apple's tablet computer.

Why? The iPad has been messing up its network.

When an iPad wants to connect to Princeton's Wi-Fi network, the device asks for permission from the university's Dynamic Host Configuration Protocol (DHCP) system. The school's Wi-Fi basically replies with, "Of course you can use our network. Here's your temporary IP address, which you'll need to get around the Internet. You're free to use this IP address for the next few hours. But, Mr. iPad, please let us know if you'd like to keep it for longer. If you don't renew it, we'll give the IP address to another computer so that they can use our Wi-Fi."

It's common for these temporary IP addresses to change hands every six hours. But some iPads seem to keep using their assigned numbers without renewing them.

"The iPad owner is often unaware of any problem," writes Princeton's computer staff. "Nevertheless, it is an issue because it can interfere with service to other devices. Once the iPad has allowed its DHCP lease to expire, the DHCP server may lease the same IP address to another client."

When these overlaps occurs, they can confuse the Wi-Fi system, the iPad, and the next computer that checks out the IP address. Princeton says about half of the iPads using Princeton's network have malfunctioned in this way.

"When an individual iPad malfunctioned, we would contact the owner to advise him or her of the problem," the university says. "When the same iPad malfunctioned a second time, we would block that device from using our network, and contact the owner again."

While Princeton banished certain iPads from its network, it has not banned the device, as Israel has. In fact, the school has since figured out a workaround and has been communicating with Apple to solve the problem permanently.

This sounds like a classic case of first-generation woes. Apple – and every other computer company for that matter – always needs to iron out the wrinkles that come with new devices and services. Perhaps its a good time to remind readers of the Monitor's appeal for patience in an era of "buy, buy, buy!"

The Glycemic Index food list has a massive database of food with rankings according to the levels of Glycemic Index. The glycemic index ranks carbohydrates according to their effect on our blood glucose levels. Choosing low GI carbs – the ones that produce only small fluctuations in our blood glucose and insulin levels – is the secret to long-term health reducing your risk of heart disease and diabetes and is the key to sustainable weight loss.

Eating a lot of high GI foods can be detrimental to your health because it pushes your body to extremes. This is especially true if you are overweight and sedentary. Switching to eating mainly low GI carbs that slowly trickle glucose into your blood stream keeps your energy levels balanced and means you will feel fuller for longer between meals.

What are the Benefits of the Glycemic Index?

* Low GI diets help people lose and manage weight
* Low GI diets increase the body’s sensitivity to insulin
* Low GI carbs improve diabetes management
* Low GI carbs reduce the risk of heart disease
* Low GI carbs improve blood cholesterol levels
* Low GI carbs can help you manage the symptoms of PCOS
* Low GI carbs reduce hunger and keep you fuller for longer
* Low GI carbs prolong physical endurance
* High GI carbs help re-fuel carbohydrate stores after exercise

Use the free GI database to find the GI value of your favorite carbohydrate foods that have been tested over the past 25 years from all around the world.

Tax Extensions - Can't Get it Done? File for an Extension

As read in the Huffington Post


April 15 is coming up quickly, and if you haven't filed your 2010 tax returns yet, you may want to fill out a Tax Extension Form.

A Tax Extension Form allows taxpayers extra time to fill out their 2010 returns, six more months to be exact. However, the IRS notes that it is "not an extension of time to pay" and any balance due must be paid when you file your extension.

You can find the 2010 Tax Extension Form at the IRS Web site here.

The IRS specifically recommends a service called FreeFile to fill out your extension form.

The official Tax Extension Form is known as IRS Form 4868. You must file such an extension form for both federal and state taxes.

Still have questions? Sandra Block of USA Today offers a series of tips for last-minute tax filers, including the fact you can work out a payment compromise with the IRS in some extreme cases.
