I&#x27;ve been using <a href="http:&#x2F;&#x2F;www.devarist.com" rel="nofollow">http:&#x2F;&#x2F;www.devarist.com</a> (which was posted on HN back in August last year) to record little tidbits on an almost daily basis, and it&#x27;s been working pretty well.<p>If it&#x27;s something I have to look up I try to make a habit of putting it in there. Then I can do a search for the search phrase I&#x27;d normally make and it pops right up, saves me a lot of time looking through the top couple of documents for the nth time.<p>Devarist has Markdown support also. I&#x27;ve been using it to include little 20x20 icons for each programming language or technology so I can scan through the past pages to see at a glance which technology each note applies to.<p>That having been said, doing it in Github might actually be better for the public tidbits. Some things you learn kind of need to be kept private though (like your own projects, or pertaining to your job, or pointing out things you have trouble remembering to do).
