Happy New Year to all 1) My Microsoft Trackball Explorer Mouse 1.0 just shattered. Does anyone have a spare? 2) an interesting looking gadget: I don't want to sound like an advertisement but we all love gadgets and tools. At $16.90, this watchband-o-many-tools looks interesting but I'm unsure how practical it is vs.a multitool or Swiss Army knife: https://nanroucy.com/products/29-in-1-multi-tool-wearable-titanium-steel-bra... 3) DVD-R are NOT archival. My spindle of "Playo" DVD-R fail verification immediately after burning. Others have bit-rot. I vaguely recall a file system format with error checking and redundancy to compensate for that, if one had the foresight to record in that format. What are the "best practices" other than making 2-3 copies on different brands? -- Jeff Jonas
