If you do any server administration work, you’ll have worked with log files. And if your servers need to be reliable, you’ll know that log files are common source of problems, especially when you need to rotate or ship them (which is practically always). In particular, moving files around causes race conditions.
Thankfully, there are better ways. With named pipes, you can have a simple and robust logging stack, with no race conditions, and without patching your servers to support some network logging protocol.
