I hoard the information I have actually read (sometimes even stuff I did not read thoroughly) into my own, personal, searchable version of the internet, so that I can easily refer back to it, retrieve an old article and share it.
Was I the only one surprised with the variable minetypes: ['application/x-php'], focus on minetypes instead of mimetypes.
I guess they have a reason for keeping it that way, although if such a typo exists unfixed in the codebase, that gives you a general hint of the overall codebase quality.
To do that I use a paying account of pinboard.in
