What do you use to track you mistakes/accomplishments ?

As a programmer one of the most important things that you can learn is to always learn from your mistakes and to also learn from other peoples mistakes so that you do not repeat them.

What i started doing a while back as you may have noticed ,is that anytime i learn something i blog it , so that in the future (as long as the DB doesn’t crash) i can always reference stuff in the past to see how i got things done. This is also a handy way for me to explain to other people how they should over come problems that i had in the past.

Of recent times i have started a bit of a new practice and that is using SO. The reason i love using  SO is because everything i do there is recorded so if i ever need a solution to something i worked on in the past its east enough to find and as with the blog its easy to point people to a question that i worked on instead of explaining the entire solution to them again.

The basic idea behind both of these ideas is to keep a record (you don’t have to keep a diary but if you want to i wont stop you) so that you can refer back to it in the future. It has also been shown that by writing (any form of recording really) down what you learn it becomes ingrained into your way of working.

So what do you use to track and record your mistakes or accomplishments ?
