These pages describe some of my current interests. They
include the Sydney PC User Group, the PIC Club (part of the PCUG
interested in PICs or microprocessors), Web Design, prime numbers, factorising
of large integers and digital photography.
The Sydney PC User Group is an independent club of users discussing
all aspects of using personal computers and helping each other solve
computer problems. It also has several Special Interest Groups or
SIGs. More...
Microprocessors such as Programmable Integrated Circuits made by the
Microchip
company are easily programmed to perform various interesting
sensing and control functions. The PIC Club grew out of the
Programming SIG of the Sydney PCUG. More...
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.

A 102-digit personal
record prime factor has been found on
February 4th, 2009. It divides the 205-digit
number (37 × 10204 + 17) / 9 or 412033.
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. More...
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. More...
