1/19/21  The 2021a revision was easily as extensive as the revision in August because the expansion to six pages helped readers see and suggest changes/expansions to weak areas that deserved more attention.  This was true in most categories but heaviest in the reference area for data containers.  Oddly enough, a module for JSON presented one of the biggest problems.  A group’s spokesman felt it deserved a significant “mention” but it was just too complicated to do justice in a limited amount of room.  As a result an entire page was added to the Data-on-Disk toolbox just for JSON.

8/24/20 This turned out to be a monster revision. Almost every major (and many minor) segment(s) got a face-lift, a fact-lift, a revised example or demo, or all of the above if it wasn’t brand new from scratch.  This was certainly the biggest revision ever and it may be the last revision ever – it was exhausting. But surveying the many online ‘cheat sheets’, we feel it is fair to say there is nothing remotely comparable. I hope you enjoy it. All six pages are combined into one doc – the display here is 72 dpi.  The download from GitHub is 600dpi – designed to be printed front/back and laminated for quick desk reference. Secure downloads of 600 dpi pdf are from GitHub.
