The traditional "Merry Christmas" thread -- with a twist

[Helix]

I am thankful for those who invented Internet, for those who make great sites and forums like this one, and for all members here that share not only their knowledge about HP calculators, but also about other machines, post links to other instructive sites, books, or videos, or relate their past experience when calculators were not as widespread as nowadays.

I am thankful for the existence of Ebay, which permits to acquire old devices with only some patience. This year for example I have formed a small collection of nice slide rules, which would never have been possible without Internet and Ebay.

I am thankful for this intelligent use of Internet, as opposed to the lies, fake news, manipulations, intolerance and other primitive emotions that overrun some popular social media.
I wish the light side of the web will remain active and strong, and will have more influence on humanity than its dark side.

Merry Christmas
