Disk IO information with a Unix / Linux background - 0 views

  • The disk's ITR rating and internal cache size can be critical when tuning maxcontig (maximum contiguous I/O size). Note: maxphys and maxcontig must be tuned at the same time. The unit of measurement for maxphys is bytes; maxcontig is in blocks. maxcontig can be changed via the mkfs, newfs or tunefs commands.

  • Disney does mediated experiences better than anyone. If they understood what OSes are, and why people use them, they could crush Microsoft in a year or two.
  • But more importantly, it comes out of the fact that, during this century, intellectualism failed, and everyone knows it.
  • lip service
  • How badly we want it can be measured by the size of Bill Gates's fortune.
  • When TCP/IP was invented, running it was an honor reserved for Serious Computers--mainframes and high-powered minicomputers used in technical and commercial settings--and so the protocol is engineered around the assumption that every computer using it is a serious machine, capable of doing many things at once. Not to put too fine a point on it, a Unix machine.
  • Young Americans who leave their great big homogeneous country and visit some other part of the world typically go through several stages of culture shock: first, dumb wide-eyed astonishment. Then a tentative engagement with the new country's manners, cuisine, public transit systems and toilets, leading to a brief period of fatuous confidence that they are instant experts on the new country. As the visit wears on, homesickness begins to set in, and the traveler begins to appreciate, for the first time, how much he or she took for granted at home. At the same time it begins to seem obvious that many of one's own cultures and traditions are essentially arbitrary, and could have been different; driving on the right side of the road, for example. When the traveler returns home and takes stock of the experience, he or she may have learned a good deal more about America than about the country they went to visit.
  • We like plain dealings and straightforward transactions in America.
  • This would simply not be worth the effort, and so "wc" would never be written as an independent program at all. Instead users would have to wait for a word count feature to appear in a commercial software package.

Computerworld - The A-Z of Programming Languages: BASH/Bourne-Again Shell - 0 views

  • Interviews The A-Z of Programming Languages: BASH/Bourne-Again ShellWhen the Bourne Shell found its identity
  • in this article we chat to Chet Ramey about his experience maintaining Bash.
  • In BASH's case, the problem to be solved was a free software version of the Posix standard shell to be part of the GNU system.
  • ...3 more annotations...
  • the original Bourne Shell was very influential, the various System V shell releases preserved that heritage, and the Posix committee used those versions as the basis for the standard they developed. Certainly the basic language syntax and built-in commands are direct descendants of the Bourne Shell's. Bash's additional features and functionality build on what the Bourne shell provided. As for source code and internal implementation, there's no relationship at all
  • Bash will continue to evolve as both an interactive environment and a programming language. I'd like to add more features that allow interested users to extend the shell in novel ways. The programmable completion system is an example of that kind of extension.
  • Do you have any advice for up-and-coming programmers? Find an area that interests you and get involved with an existing community. There are free software projects in just about any area of programming. The nuts-and-bolts -- which language you use, what programming environment you use, where you do your work -- are not as important as the passion and interest you bring to the work itself.
