... Here is some programming information for common ports that can be directly used for general-purpose TTL (or CMOS) logic I/O. If you want to use these or other common ports for their intended purpose (e.g., to control a normal printer or modem), you should most likely use existing drivers (which are usually included in the kernel) instead of programming the ports directly as this HOWTO describes. ... The game port has a quad one-shot multivibrator (a 558 chip) connected to the four inputs. ...

multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

This module provides for mapping different parts of the host filesystem in the document tree, and for URL redirection. ... The directives contained in this module allow for manipulation and control of URLs as requests arrive at the server. ... The ScriptAlias directive has the additional effect of marking the target directory as containing only CGI scripts. The Redirect directives are used to instruct clients to make a new request with a different URL. ... Syntax: Alias URL-path file-path | ...

... Apache HTTP Server Version 2.2 . ... Any file that has the mime type application/x-httpd-cgi or handler cgi-script (Apache 1.1 or later) will be treated as a CGI script, and run by the server, with its output being returned to the client. ... The default behavior, if AcceptPathInfo is not given, is that mod_cgi will accept path info (trailing /more/path/info following the script filename in the URI), while the core server will return a 404 NOT FOUND error for requests with additional path info. ...
