Street View oddity
Using Google Street View I was travelling north along Oak Tree Lane in Bournville (52.42962464016648, -1.939732965681817) and passed the same woman (grey jacket, purple bag) three times at different locations. How is that possible? The weather/lighting conditions seem to be the same so I assume all the photos were taken on the same day. Does this sort of thing happen a lot?

 * Looks like to google person travelled north to south. After catching up with the woman for the first time, the google person may have gone into Westholme Croft. This being a cul-de-sac, they had to turn around to continue their descent down Oak Tree Lane, when they caught up with the woman again. If you pay attention to the guy with the dog as well (who walks some distance behind the woman) you should be able to stitch together the time sequence. Doesn't look mysterious to me... --Wrongfilter (talk) 10:04, 5 November 2022 (UTC)
 * Ah, I didn't notice the cu-de-sac. In that case a simliar phenomenon should occur where there are other culs-de-sac, so I shall check those out. Shantavira|feed me 12:42, 5 November 2022 (UTC)
 * Just to note, I see this kind of thing all the time on street view. It's not unusual. Viriditas (talk) 20:50, 8 November 2022 (UTC)

Early plotting library
Which plotting software was used here? Sorry for not knowing the date it was taken. Oure Ladye (talk) 21:52, 5 November 2022 (UTC)


 * The JPEG file has the timestamp 2014:06:12:17:30:25, but the photograph cannot actually be that recent. I could not find dates for the span of the AMRF, but it seems to have been closed by 1990. --Lambiam 03:58, 6 November 2022 (UTC)
 * MATLAB was released in 1979, while gnuplot and Mathematica both were released in the 1980s. I don't know which of these already had 3D plot capabilities in the 1980s. It is possible that the software was proprietary to Hewlett-Packard and came with the graphics workstation shown, or that it was developed in-house by NIST. --Lambiam 10:48, 6 November 2022 (UTC)
 * The HP 9836 in the photo came with image, a database, and graph, a graphing tool that could do 3D graphs. 97.82.165.112 (talk) 00:31, 7 November 2022 (UTC)
 * Here the 3D graphic program is named "graph 9000". --Lambiam 17:01, 8 November 2022 (UTC)
