Alternate Web-page Style

Here is a mirror of this web-site, but in a parallel universe using black text on a pale background.



Using exponents up to 30,000, primes of the form k • 2n ± 1 were calculated using the latest version of the free OPENpfgw program available from SourceForge.


Digital Photos

More photos have been added. See our friend Bill G and a "floating ship" which appears to hang suspended above the horizon.



See my personal Blog: bobb777 and the Blog of the Sydney PC User Group: sydneypcug.


Windows 10

See screen-shots of various Insider Builds of Windows 10.


Windows 7

See some screen-shots of Windows 7.



The latest addition is an Unscramble program to solve Jumble™ puzzles.


Sydney PCUG

The Sydney PC User Group is an independent club of users discussing all aspects of personal computers.

The members also help each other solve computer problems. It has several Special Interest Groups or SIGs including Family History (Genealogy), Digital Photography and Web Design.


Web Design

This web-page was initially written with NetObjects Fusion, one of the programs used by the Web Design SIG. See the Reports for recent meeting information.

More recently I've written some Perl scripts to construct web-pages based on tables of integer factors that I have discovered.


The DOS ftp command

Use the inbuilt DOS ftp command to upload files quickly from a batch file. If uploading different files each time, however, use a Windows FTP program like the free Core-FTP program instead.

Read the details in this short tutorial.


Soft Hyphens

See what soft hyphens are all about. Enable Javascript and check out your browser by loading this test page. We check the Windows version of Apple's Safari browser.



Unicodes may be necessary in HTML when named symbols are not available (for Cyrillic characters Я and и for example).


HTML and XHTML Validation

Check that you have valid HTML or XHTML code online using the World Wide Web Consortium (W3C) official site or offline using the free CSE HTML Validator Lite program.


Factors of Large Integers

A 112-digit personal record prime factor has been found on April 1st, 2016. It divides the 226-digit number 7 • 2746 + 1 = p112 • p114.

Work is progressing on factorising numbers of the form k • 2n ± 1 with k (odd) from 3 to 15 and n ≤ 1000. The results are recorded by Mikael Klasson.


Factoring Program, Msieve

Msieve, written by Jason Papadopoulos is described. It contains fast code to solve large sets of linear equations. See the new Perl script to automate Msieve post-processing after a GGNFS run.
