Keeping track of code snippets, network diagrams, IP allocations, complex syntax and everything else that a typical coder/sysadmin deals with requires a solid knowledge base.
Gists at Github are excellent for storing code snippets. They can even be made public so others could use them also. I was using Snipplr up until now, and it worked out great especially with the TextMate integration. Since I moved my code repositories to Github, I wanted to everything in 1 central place.
Evernote allows you to make separate notebooks and tags which makes organizing your knowledge base pretty simple. The best part though, is the syncing. I am using the Mac and Android apps which sync to evernote.com, so I always have access to my stuff. Adding any type of files within a note is super handy. For instance, I put my network diagram OmniGraffle file in a note and now when I edit the file in OmniGraffle, it automatically saves in the Evernote! Evernote seems to offer a ton of features such as OCR and sharing, but I haven’t explored them much yet.
I am very excited about how both of these services will be increasing my efficiency as I move more of my data into Evernote and Github. Should save tons of time by having access to this info anywhere I go and eliminating having to search a variety of sources.
