Now I know that only the geekiest amongst you will have any clue at all what you're seeing there. If you're curious, everything you need to understand it is available here. That output was generated with “ntpq -p”; it's a peers report. The important bits to me are where I've highlighted it in orange: that's the offset and jitter, in milliseconds, for my little NTP server. A zero in those measurements would be perfect; I'm pretty darned close! :) My GPS-based timing unit is currently reporting (separately) a maximum error of 8 nanoseconds in it's pulse-per-second output, and that's what my NTP server is using for a reference (that's what the “oPPS(0)” refers to). The other interesting piece of information I see is highlighted in red. That's telling me that the toofishes.net NTP server I'm using as a possible reference has not responded to 3 of the last 8 queries my NTP server sent to it. The “-” at the far left of that line tells me that my NTP server is ignoring it, most likely because of these errors.
Yesterday Debbie and I went to Aggie's Creamery for an ice cream cone. Of course, as always, they were outrageously delicious. When I first walked in, there were only two other customers there; they had just finished getting their ice cream. One was a young woman, perhaps 25 years old. The other was a much older man, maybe 85 or 90, very frail, a little confused, barely able to walk. The young woman was, I suspect, his granddaughter. I watched them, unseen, for a minute or so, just delighted by the scene. The young woman was very solicitous of the old man, watching out and helping in many little ways. She was clearly happy about his reaction to the ice cream: he was enjoying his little cup of chocolate wonderfulness at the same time she was trying to guide him into the safety of a seat at a little table. He was distracted by everything: the shop, the bustling employees, the task of getting a spoonful of ice cream into his mouth, and the difficulty of walking in his condition. Nevertheless, there was a huge grin on his face and he was making utterly unrestrained happy noises. The young woman finally got him safely down, and as she sat down she turned toward me – and I could see her happy satisfaction with the moment. She glanced at me and she saw my smile and thumbs up, and responded with a big grin of her own. Just a sweet, happy moment: a younger person taking pleasure in making someone she cares about happy. And in that she certainly succeeded...
