Prime Numbers and Other Interesting Things

Some of my photos, arranged by date, mostly birds. Some of my photos are also at (offsite) https://1-john-moyer.pixels.com/galleries.html and may be purchased as wall art or on products such as tee-shirts, towels, coffee mugs, and puzzles. If you wish to license one of my images for your own use, some are available at (offsite) https://licensing.pixels.com/art/all/john+moyer/all or you may email me to license an image not listed there.
This was written before 2001 and likely will not work in a modern browser or will not work without many scary warnings. The source code is still available and still works today under the Iced Tea version of Java. Find the next prime number larger than an integer you provide. This is a JAVA program and requires a new enough JAVA in your web browser to include the java.math.BigInteger package. Source code is here.
Find the next ten prime numbers after the integer you provide. There is a credit for this code in libboost. http://www.boost.org/doc/libs/1_64_0/boost/multi_index/detail/bucket_array.hpp This may no longer work after my web server upgrade because it was compiled to run on a 80386.
Source code for a sieve program to find prime numbers: sieve2310.c or embedded in html for easy viewing with Internet Explorer sieve2310.c.html
Find primes using a recursive formula by Rowland. C and C++ source code to find prime numbers by using a recursive formula. 10,000,000,000 iterations found 65 unique prime numbers, the largest 7972334723. Run time was about 38 minutes on a fast 64 bit linux computer.
Print all of the primes within a range of integers. These are from a file containing all of the primes less than 8000000000.

/*
The following 160 character C program, written by Dik T. Winter at CWI,
computes pi to 800 decimal digits.
*/
int a=10000,b,c=2800,d,e,f[2801],g;main(){for(;b-c;)f[b++]=a/5;
for(;d=0,g=c*2;c-=14,printf("%.4d",e+d/a),e=d%a)for(b=c;d+=f[b]*a,
f[b]=d%--g,d/=g--,--b;d*=b);}

(Offsite) http://iosrjournals.org/iosr-jm/papers/Vol10-issue4/Version-3/C010431317.pdf provides another method for calculating pi.
(Offsite) More about pi at http://crd.lbl.gov/~dhbailey/ (link no longer works) and http://www.lacim.uqam.ca/~plouffe/ (link no longer works) On March 14, 2024, I found a copy of a DH Bailey paper at https://www.davidhbailey.com/dhbpapers/pi-quest.pdf

Refraction of C band satellite signals.
mkthumbindex.sh: I wrote a shell script that creates a html (web page) index of a directory full of jpeg images. Requires ImageMagick.org and bash or ksh to run. The output is similar to the photos of Ireland web pages referred to by the next two links. This script uses html 4.01 and Cascading Style Sheets. Thumbnail images are created by the convert program that is part of ImageMagick. In the resulting web page, one may click on the thumbnail or on the file name to view the image. The script works fine under Unix or Linux, but may need to be changed to run under windows.
Photos of Ireland from my trip there in January, 2004. One of my photos of palm trees growing in Ireland is included in a paper on rapid climate change at http://downloads.globalchange.gov/sap/sap3-4/sap3-4-final-report-ch1.pdf.

(Offsite) The history of the "Moyer" name is at http://www.gameo.org/encyclopedia/contents/M694ME.html. Manasseh Moyer, mentioned on that page, was my great-grandfather.

(Offsite) The history of the "Latschar" name is at http://www.gameo.org/encyclopedia/contents/L387ME.html. Some of my ancestors were named Latschar. A brother of one of my Latschar ancestors bought land from the founder of the Amish.
