Is Your Head in the Clouds? Len Calderone

Apr 2012

 Basically cloud computing is a data center on-demand. It is an unstructured infrastructure owned and operated by someone outside of its customers’ company that accepts and runs workloads created by its customers. Previously, if a company needed more computing power, it added more servers, but for a small company, this is not cost effective. Using cloud computing, a company can plug into the Internet to access more computing power, which is scalable; meaning that as the demand changes, the cloud system will scale up or down.

The Technologies, Market, Industry support factors that are driving the SDR approach are narrated. The architecture and the components that make up the SDR are explained and illustrated for the purpose of understanding the technology. And also, the hardware and software components required to build a practical SDR are investigated. The recent availability of multi processors, FPGA, software reference models, and developmental tools that are accelerating the penetration of SDR into the cellular market are explained and reviewed. Currently available SDR reference systems and their modular and extensible architecture are also presented for sake of designers. The market trends and predictions for the SDR are discussed.

 Why jacks? Why not just “hardwire” everything? Because today’s homeowners live in a dynamic world. New things replace old, new lifestyles mean rooms change their function and jacks let you plug things in and out, as you wish.
Casio PhoneMate IT-380

Dec 1998

 No, the unit doesn't get the body of the messages (it leaves those in your mailbox for retrieval with a PC). The IT-380 is designed to be an "E-mail advisory device" or Internet appliance, meaning that it informs you that you have new E-mail without providing the full message text; it is not designed for sending and receiving E-mail. My first impression of this limitation was negative but then when I thought about it, I realized that I really don't want a phone to get my email anyway. How would I type in a reply, organize and save messages etc. with a keypad. And what attachments ... where would they go ... lost in cyberspace forever?
