The faintest ink is better than the best memory.
Keeping record is important. This is my blog. Originally blogs were created by people who wanted to create a web log (a.k.a. blog). It’s a way to share your knowledge and also keep a track of useful information that you might want to reference in the future. I compare it to the Pensieve in the Harry Potter books.
It’s a pensieve, useful if like me you find your mind a wee bit stretched. (Dumbledore)
Hopefully you also find something useful here too.
