I'll look into those, but do take note those books are 14 and 18 years |
| 26 |
old - that's eternity in our world. |

Basics never change, details do. Some features are here for the long |
| 29 |
haul and I doubt anything will really change them: pipes, named pipes, |
| 30 |
unix sockets and things of that ilk. The real bugbear with IPC is people |
| 31 |
reinventing the wheel over and over and over to do simple messaging - |
| 32 |
writing little daemons that do very little except listen for a small |
| 33 |
number of messages from localhost and react to them. |
| 34 |
|
| 35 |
Use a generic message bus for that! It fits nicely in the grand Unix |
| 36 |
tradition of do one job and do it well, and few apps have passing |
| 37 |
messages around as their core function. Hand it off to the system, |
| 38 |
that's what it's there for. |
| 39 |
|

One day I might well do an audit of a typical server base system and |
| 41 |
count all the apps that have a hidden roll-your-own message process in |
| 42 |
place. I'm certain the results will be scary. |
