Generating Random numbers to conform a distribution (David V Glasgow)
Perhaps this helps: I needed lists of samples that obeyed a certain distribution for a few random experiments. I created these with help of built-in Excel-functions and then imported them into Livecode.

Helo Paul,
It works! Thank you!

Hello, My Mac is by usb connected to an iPhone, on which is running the data-aggregator Phybox.app and aggregates the sensor-data of the internal acceleration-sensor. On Mac, when I write into the Safari address bar "http://192.168.178.66/export?format=1“, I receive the sampled data in a .xls-file by download from the iPhone-app. I would like to download this file by LiveCode. But I have no plan, how to do it. May you help? I am very grateful for tips.

Re: Has anyone experience of GPS on iPhone?
Hello Graham, 20 years ago I started to use GPS-technique and found the same mysteries as you do now. I learned that there a two main reason for the variation of location data: Atmosperic density variations cause short term runtime variations and Different relativ positions of satellites cause long term triangulation errors. So I sampled at a constant location over some days the position data delivered from a gps-receiver taken every 10 seonds. First I plotted the data and found that there were local shorttime-variations around a center, which was wandering slowly over the plot-area. The shorttime-fluctuations were most in a range of +-5m, the longtime-area showed - if I remember right - a radius from +-20m. After that I started to calculate time-series of mean-values over different minute-intervalls and learned by plotting the result again, how to smooth my data best. Nowadays you will of course get smaller short-time variations using the more intelligent gps-receiver of an iphone, but it probably gives you an impression about what is going on there.

shell() and pdftotext
Hello, I want to extract .txt from a pdf-file using Livecode 9.5 on macOS Catalina. Therefore I installed from http://www.xpdfreader.com/ the xpdf-tools-mac-4.02 and using the Terminal with „pdftotext /Users/hillen/Desktop/inter.pdf“ I get a clean text-file inter.txt. Wonderful! So I hopefully wrote in Livecode: —— put "/users/hillen/Desktop/inter.pdf" into fn put "pdftotext " & fn into Kommando if there is not a file fn then answer „no SourceFile!" exit to top end if get shell(quote & Kommando & quote) answer it & return & the result —— But extracting doesn´t work and I get the answer: /bin/sh: line 1: pdftotext /users ……pdf: No such file or directory and the result ist 127. Typing to Terminal „pdftotext“ I get a List with command-options. With get shell(„pdftotext“) with and without quotes I get the answer „/bin/sh: line 1: pdftotext: command not found“ What is wrong? May you please help?

can´t save Standalone
Hello, There is - in splash screen method - a very simple stack Main with a substack Data, used since 2007. Stack Main opens stack Data. In stack Data there is a button "Save" with script "save this stack if the result is not empty then answer the result" Using this proved datastack-method in the development environment, it´s ok; But after making a new standalone with "substacks moved in separate stackfiles" if I press the Save-button in stack Data I get "can´t open stack backup file". So I cant´t save changed data. I have built the stack from button up again with the actual LC-Version, but same Error. Is there any help outside? Thank you for your helpful hints , Richard.
