Logging

I love logging. In many ways it's more useful than a debugger. Long ago I wrote a simple logger, and I still use it, or nowadays Java has a built-in logger, and in my experience it's fine.

But I hate Log4J. There's one straightforward reason: by default, Log4j does nothing useful. I couldn't count the times I've seen "Please initialize the Log4J system correctly" as if it were my fault. It's a logger doesn't log!

Another reason is that to specify a daily rolling log file (which is almost always what you want) requires 5 (or more) lines of configuration.

So here's a rule for writing any software. Do the simplest useful thing by default, and make the most likely use cases as simple as possible. Log4J fails on both counts.

...so that's why I could never figure out how to get Log4j to work. Because it was not designed to do anything. GUH.
