How to write Controller & Integration Tests in Rails Discussion
Hi Chris great job! What is the difference of the integration test with the controller test
JAPANFAXBROADCASTLIST It was not that long ago that cell phones were a luxury, not a necessity. Anyone over the age of 30 will remember the days when wireless phones were big and bulky with average reception and limited coverage at best. As hard as it is to imagine now, cell phones of yesterday had one function and one function only - to make and receive calls.
How times change.... Even the most basic cell phones of 2007 pack more computing and navigational power than was used on early NASA space missions!
And as you would expect, business people have become emotionally attached to their personal cell phones and wireless technological devices. So much so that there are now specialists treating addictions to advanced wireless devices such as the Blackberry and other e-mail capable "smart" phones. Studies have shown that addictions to cell phones and wireless Blackberry e-mail are as powerful as heroin addiction!
We have tracked down some of the latest cell phones and features that eventually you may not be able to live without. If you suffer from cell phone or PDA addictions, this list may make it that much harder to kick the habit.
Wi-Fi Cell Phones
If you have ever had a call "drop out" for a brief period of time, you will appreciate the introduction of the Wi-Fi cell phone. This handy device can automatically switch between conventional cellular and Wi-Fi VoIP modes - even during the course of normal conversation.
Dense urban areas that contain large buildings made of concrete and steel continue to pose problems for conventional cellular signals. These structures have a tendency to block the radio frequencies needed to maintain wireless call connection to a "repeater" - the device that picks up your signal and makes the call possible. If a phone is near the limit of a repeater's range and the user walks from the outdoors to indoors, the call can easily be dropped out of the network.
The Wi-Fi cell phone eliminates this dropout by automatically and seamlessly connecting to the closest Wi-Fi hotspot. With Wi-Fi becoming more and more popular and widespread, look for many more handsets to carry this feature in the near future.
The Breathalyzer-Enabled Cell Phone
You have been out celebrating a new promotion with colleagues and business associates. No longer do you have to wonder whether or not you have had one too many to drive home. Introducing: The Breathalyzer Cell Phone.
The breathalyzer cellular phone is a handset that is equipped with a built-in device for detecting ethyl alcohol vapor on the breath. The Korean company LG manufactures a breathalyzer cell phone (LP4100) that is already in use by thousands of Korean customers.
Many predict this feature will be integrated into more handsets from a variety of companies sooner than later. The breathalyzer wireless phone is especially handy for the college-age crowd or for the business person who is required to constantly entertain clients or prospective clients. The breathalyzer cell phone will undoubtedly save lives as its use becomes more popular.
