How often did you run into a problem, googled for it and eventually found a solution because someone else had had the same problem?
In this process, the key issue is to find a good query for Google.
Wouldn’t it be nice if your computer would support you here?
It wouldn’t even be hard to implement: When an error happens, programming languages have context, say, a stack trace. Some programs like the H2 database and Maven already use something like that: Every error message contains a URL where you can find additional information.
So what we would need is a wiki for stack traces.
And a plug-in for our favorite IDE to find similar stack traces in this wiki.
Kudos go to Marcel Bruch for the idea.
