startmovingforward
Adding to the bookmarks now before I forget, that is how good this is, and a look at startmovingforward confirmed the rest of the site is worth saving too, this is one of those rare finds that justifies the time spent searching the web for once which is a relief in the current environment.
inobrat
Glad I stumbled across this post, the explanations actually make sense without needing background knowledge to follow along, and after a stop at inobrat the same was true there, no assumptions about the reader just clear writing that anyone can understand from the first line right through to the end.
learnandadvancefaster
My professional context would benefit from having this kind of resource available, and a look at learnandadvancefaster extended the professional applicability, the rare site that contributes meaningfully to professional work rather than just personal interest is content with multiplied value and this one is providing that professional utility consistently across multiple pieces.
