Some people come here for my Fortran page. Others want my PhD thesis titled Quantum Waveguide Theory (which is available from the UWA library) or my Honours thesis titled Quantum Chaos in Second Harmonic Generation - Stu.

Drink up for Australia Day

So, am I the worst Australian? I get a mate to hang out in a cold machine room fixing a computer for me on Australia day.  How wrong is that?

Luckily he was an American so probably didn't understand what all the fuss was about.

20 year reunion over

Was a wild night.  Awesome fun.  Looking forward to the next.

I love screen.  I use it every day, have logins on probably 50 systems running for, sometimes, years.  I suspect this is how I'll end up .

checksum tar

Ever wanted to checksum a tar file as you write it to tape so that you can confirm the tar file without re-reading your data off disk?

First, create a tiny script called

tee >(md5sum > chksum.txt)
Then you can do
tar --use-compress-program -cvf /dev/st0 mydir > filelist1.txt 2>&1
mv chksum.txt chksum1.txt
mt -f /dev/st0 rewind
tar --use-compress-program -tf /dev/st0 > filelist2.txt
mv chksum.txt chksum2.txt
diff chksum1.txt chksum2.txt
diff filelist1.txt filelist2.txt

OK, so the old blog has now been moved across.

After months of not being able to post stuff, I can continue my ramblings.


Slowly getting my old blog moved across.  Up to 2008 now.

Moved again

OK, after getting pissed off with my last blog software and trying to update it... I've now decided to move to google provided blogging.  Google now owns my entire life.

Hold on tight while I move across my old blog.  Luckily, I was slack, which means their isn't that much to move :)
