]]> Comment on John Backus, Computer Science pioneer by ken mikelinich http://software.unh.edu/2009/09/15/john-backus-computer-science-pioneer/comment-page-1/#comment-525 ken mikelinich Tue, 06 Oct 2009 14:55:37 +0000 http://software.unh.edu/?p=323#comment-525 In my industrial telecom days we utilized ASN.1 or Abstract Syntax Notation. ASN.1 is a standard way to describe a message (a unit of application data) that can be sent or received in a network. ASN.1 tends to be very grammar efficient. Tie this in with BER or PER (Basic Encoding Rules or Packed Encoding Rules) and you have the foundation for many telecom protocols out in the Internet and PSTN today. One my early projects entailed writing encoders/decoders for GR303 and V5x protocols. These were the North American and European replacements for the older SLC96 systems. Basically these protocols handled the information exchange between the Central Office's (CO) digital switch and the remote terminal (RT). RT's are the funny looking stacks of green boxes one sees in neighborhoods. These boxes tie in the last mile of copper from your house, from there your voice call is multiplexed and backhauled on a T1 (or E1) circuit back to the digital switch. The GR303 and V5x protocols not only enabled channel muxing, but would indicate on-hook, off-hook, caller ID and other states.

Who needs SQL? CIS Unix user databases have been handled by Berkeley DB files for years; although I wouldn't hold the system up as a model for software design, it's been very solid and (cross fingers) reliable.

Even the time stamp shown on the page is identical. I've refreshed the page many times but have failed to get the humorous title to re-appear.
