| Sendmail VRFY | 2004 09 | ||||
| - In the process of doing some testing of a mail server, I noticed a piece of spam mail delivered to an address that no one should have known about.

| Parallel printer cable length | 2004 07 | ||||
| - The docs for OS/2 stated that 6 feet was the maximum length the printer cable could be for a parallel port connection. So, I guess the OS has something to do with this spec? Limits to Parallel printer cable length. Given that reliable parallel port operation limits one to a cable length of no more than 15 feet, network print servers make a lot more sense. - | |||||
| FAQ - How can I make a printer that will print to a file? | 2004 06 | ||||
| - Setting up a printer that will print to a file can be useful for any number of reasons. - | |||||
| Process scheduling | 2004 08 | ||||
| - Process scheduling is obviously important on multi-user systems. It's also important on systems we use as individuals. For example, contrast the startup of my Mac OS X box and my wife's XP system. Both have certain programs set to start up at login, but they obviously handle the scheduling much differently. On the Mac, I can click into any process that has started and can use it while other programs are still starting. On XP, I can't: the other programs will command the CPU's attention until everything is running. - | |||||

| file replication over WAN | 2005 08 | ||||
| - I am curious if anybody had any lack with real-time asynchronous file replication for SCO OpenServer over WAN? There are a lot of Windows programs that do that very nicely (Double Take, for example), but nothing that I could find for SCO. One way would be to set up Samba and use a Windows machine as an intermediary, but there must be a more economical solution. - | |||||
