There was some discussion about 'CEPH?' and similar things.
We got on to 'R' because we were discussing programming languages. Here's a summary of current popular ones: https://www.techrepublic.com/article/10-programming-languages-developers-used-most-in-the-past-year/ And a bit of fun using terminal on an android tablet to ssh into a Raspberry Pi and then editing with nano. The damned up/down arrows and CTRL/ALT kept disappearing. Peter On 03/07/2019 08:51, Ralph Corderoy wrote:
Hi, We sat on the ‘pub garden’ benches all evening and enjoyed the sun for a long time as the playing fields meant no buildings cast an early shadow. The Raspberry Pi 4 got several mentions. https://blog.hackster.io/meet-the-new-raspberry-pi-4-model-b-9b4698c284 is a good review of the improvements. Given they planned four silicon revisions, A0, B0, C0, and C1, and they've released B0 because it ‘turned out to be production-ready’, I'll wait a month of two and see if others find problems. :-) Especially as I'd want the 4 GiB version for a desktop machine. Talking of desktops, here's using two ‘4 K’ TVs, really UHDTV1, as computer monitors, one of which is also the desk surface. https://twitter.com/andrewculver/status/826948468803457024/ The four woods used by a player in bowls are no longer allowed to have an internal weight for bias. Instead, they must have a visible dimple in the surface from a permitted range of sizes. Peter M. and Patrick were asking about R. It's a modern programming language for statistics and data analysis, with many packages available to re-use, and has some nice charting ability. It's mostly a superset of the S language from Bell Labs, them again, in 1976. https://www.r-project.org/about.html An article I recently read happens to use R to map the biased samples of ‘think of a number between 1 and 10’ from a large population to a data set that provides an unbiased answer by solving a linear programming problem using R. Even if you just ‘look at the pictures’, the animation neatly shows how the samples are mapped; search for ‘animate’ and it's just below. https://torvaney.github.io/projects/human-rng Why the two-tone high-low train signal sounds to me like ‘Hitler’. https://www.rssb.co.uk/rgs/standards/GMRT2484%20Iss%202.pdf says the horns' frequencies are 370 Hz ± 20 Hz 311 Hz ± 20 Hz https://en.wikipedia.org/wiki/Piano_key_frequencies#List maps those near enough to F♯4 369.9944 D♯4 311.1270 and they are three semitones apart and a minor third. https://en.wikipedia.org/wiki/Colonel_Bogey_March#History says Supposedly, the tune was inspired by a military man and golfer who whistled a characteristic two-note phrase (a descending minor third interval) instead of shouting "Fore!"
