During the time I was active in the old Museum of HP Calculators (very active since May 9th, 2001) I posted some 1,897 posts and created 136 threads over the years, and since I've signed up to the new version I've posted several hundred more. As searching for a particular post in the old forum can be quite time-consuming (and even a hit-or-miss affair if you're not quite sure about the exact description of what you're trying to find), I've included here a selection of the 100 Best threads either directly created by me or featuring some of my best posts, carefully chosen one by one to include most of my allegedly very best posts, mainly the ones where I discuss programming techniques, math algorithms and topics, or give useful routines and program snippets to illustrate or solve some problem or other peoples' challenges.
The selection features also some threads which do not include any posts from me but where some of my posts or articles are extensively discussed by others, or include substantial discussions about me or my circumstances. Also, though the threads in the selection are usually included in full in the PDF, a number of them are trimmed to include only the parts relevant to me or my posts or which are necessary for comprehension. The reason is that many, many threads usually stay focused for a while but then digress enormously, with hundreds of subsequent posts having nothing to do with the original subject at all. I see no need to include such threads in all their length and so I trim them to just the relevant parts, which makes for much less space used and much more convenience afforded. In any case, the full-length thread can be consulted if desired without further search, as I give every thread's original URL in their own PDF.
Last but not least, these threads also do not include the ones I created to post my Challenges of all kinds, which you can find in the HP Calculator Challenges Category in this site. I might add to the selected threads in the future, so keep your eyes peeled !
