Brazil's National Health Care System

Brazil is an amazing country.  I would love to visit there some time to learn how they can be so forward thinking and progressive.  Here are some interesting statistics about Brazil and Health Care System:

• The Brazilian National Health Care System treats about 1.2 million inpatients and 100 million outpatients per month, providing everything from immunization to heart transplants.
• Complex, diverse computing systems that can effectively exchange huge amounts of patient data are a central requirement of a seamless health care system
• One of the main goals of the BNHCP was to avoid vendor lock-in or proprietary technology.  
• Two technologies -- Java technology and the XML data format -- were chosen to achieve this goal.  
• The nature of the project called for multiple vendors and system integrators to implement the system, and it was necessary to ease integration without hampering the different implementations.  
• XML, Java technology, and HTTP were used as the "glue" to bring these diverse implementations together relatively quickly.
  

40th Anniversary of the First Internet Message

Yesterday, October 29th, 2009 was the 40th anniversary of the first message sent on the Internet.

The two letter sent were "lo"  as in "lo and behold", but they were trying to get "login".

As CNN reported when speaking with Leonard Kleinrock:

"But there was no other computer to talk to. So a month later, Stanford Research Institute received its interface message processor, or IMP, connected it to their host computer, and we created the first piece of the backbone network when a 50-kilobit-per-second line was connected between UCLA and SRI.

What we wanted to do was send a message essentially from UCLA to SRI's host. And frankly, all we wanted to do was log in -- to type an l-o-g, and the remote time-sharing system knows what you're trying to do."

The systems crashed after the second letter was sent.  Leonard Kleinrock of UCLA sent the message from UCLA to Stanford Research Institute (SRI).  The two letters traveled about 400 miles.

As National Geograpic reports, "Packet-switching was the original transmission mechanism [for our network] in 1969 and is still the underlying technology of the Internet today," said Kleinrock.

Here is a great picture of the Interface Message Processor (IMP) that sent the first message.
