The world is full of unsolved but tractable problems. One of my recent projects needed an AWS spot market simulator but all the obvious searches didn't turn up anything so I went ahead and wrote one for my use cases.
Another, but slightly smaller, problem was about writing to and rotating logs based on number of lines instead of file size or timestamps and again the obvious searches turned up no results so again I wrote something.
Never be afraid to tackle small and tractable problems. Never let the haters get in the way of making and sharing something because there are people out there that will find your work useful and at the end of the day that's what counts.
