From Mt Dandenong to Lorne (or further)

The problem with making weekend trips is of course figuring out when to organize the zillion photo’s you’ve made, make a decent selection and then recall the where’s and why’s of each of them. Last Friday me and Majid went up Mt Dandenong (with 630 meters the highest peak of the Dandenong Hills), which you might still consider within the Melbourne metropolitan area, albeit this area is mostly used by retiries or seasonal visitors. Nonethless, on top of the thing is a beautiful observation site, which on a clear day gives you a pretty spectacular view over the Melbourna area. Great way to spend a friday morning.

note below the tiny high-rise area, that’s the CBD. Monash uni is somewhere in the middle.

On Sunday I was picked up by Jenny and Neil for a road trip toward the other side of the Melbourne area (Geelong and the Great Ocean Road).

This truly was an apetizer for the trip me and Christine will make in a month or so. Ozzies mean business when going for a ride. If you would take this trip starting from Delft towards the West you’d be having fish and chips in Norwich, to the South you would be paying toll in Amiens and to the east be driving 200 km/h on the Autobahn past Dortmund. Anyway, distances are looked upon differently here and understandably so. There simply is a tremendous amount of distance between places. Then again, the worst that can happen is having to stop for a coffee …

or play around with your board a bit

walk the dog

or stay on dry land and enjoy the views

and after a couple-a-hour drive up and down the Great Ocean Road you take the ferry from Queenscliff to the eastern side of the bay-area "embracing" Melbourne and a final 80 km freeway trip back to Clayton.

Yep, although the Melbourne weather this past week has been pretty much like home (in a summer that is), this was a wonderful Sunday trip with great views, talks, drinks and food. Thanks Jenny and Neil!

Short course australian english (part 1)

To emphasize that I’m not in Melbourne just for coffee, zoos, beaches and what have you more, I will regularly update you with some of the essentials regarding the native version of the English language. For example, Ozzies (australian people) will immediately understand if you want them to pass you the dead horse (hand over the tomato ketchup). If not, they’ll most likely tell you to wreck off or if they’re offended to spit the dummy (ease up). If (God forbid) you wind up in some remote camping ground, you might have to take a leak in a Dunny (outside toilet) where you might possibly encounter a Dunny Budgy (a blowfly hanging out in a dunny), which according to the locals here is the most disgusting insect on this island and possibly the planet. But hey, another day, another dollar, before you know it you’ll be fresh as a daisy 😉

And the winner is … Blijdorp!

Todays trip – one I had looked forward to quite a bit – is the Melbourne Zoo next to the Royal Park, a few miles North of Melbourne CBD and in true Melbourne fashion a little over 50 minutes by train from Clayton, the Melbourne suburb I’m living in. I have always had a keen interest in and fondness for zoos, of which in my mind Burgers’ in Arnhem, Noorderdierenpark in Emmen and Blijdorp in Rotterdam are some of the finest examples around the world, and this I say without any chauvinism. Zoos in my view have little to do with preservationism – although they might in the not so distant future – but are there for us so that we can gaze at creatures we scared out of our immediate habitats (in some cases with good reason), and learn and wonder what wonderful creatures have evolved before we accidentally fluked out of the evolutionary equation.


One of the things I get from wondering through zoos is some perspective on the mindless hurry we’re all in – at least the one I’m in. Take lizards and lions. Both are exceptionally good at doing as little as possible. The first because it is cold-blooded implying it needs the environment to gear it up into action, and the second because it has little incentive to do anything other than sleep 20 hours a day.


Any one maintaining that zoos are essentially cruel institutions depriving animals from their wonderful wild habitats, I recommend reading Life of Pi, written by the Canadian novellist Yann Martel. Although the (by the way wonderful) novel is of course entirely fictional, Martel poses the clever question what damage (proper and caring) zoos exactly do in sheltering animals from the blessings of daily survival such as running for your life, a zillion deseases and fierce competition for space, food and spouses. If that is a morally wrong thing to do we might want to rethink medicine, food aid programs, piece talks and many other things.


I like zoos. But I am somewhat dissapointed by the Melbourne zoo. In true Melbourne style, it could have been large and spacious with savannahs full of hopping kangaroos, impressive croc enclosures, aquaria full of queensland wonders and the likes. Don’t get me wrong, the zoo takes good care of its animals, the enclosures are clean and neat, but most space is in fact allocated for homo sapiens, particularly the small and noisy ones. I didn’t pay 26 dollars to hear their quif clamours. More over, it closes (on a sunday in summer!) at 5 o’clock and sells lousy coffee – if at all, the coffee corner shuts its doors at 4 o’clock. A clear 1-0 for Blijdorp …

The beach on a sunday afternoon

There are many things that Melbourne (the metropolitan area as a whole) has in common with the randstad. The populated area is about the same size, approximately the same amount of people live there and there is a wonderfull beach area. For example, in bot cases you might encounter these images:

On the other hand, there are many differences, for example, you’ll be hard-pressed to see these grow in Scheveningen

nor would you look about 6 miles to the North and see this (remember skydeck?)


or find crocodile dundee and his sons throwing a line or two

In fact, you can not set one foot past the next without accidentally bumping into a palm tree or some other proof that this place is serious about its climate and its desire to force its population into shorts and t-shirts, and total relaxednes.

Wasn’t there any bad news? Only very temporarily …

But no worries mate, next friday it’ll start to rain again


The blues on a saturday evening

Regardless of how wonderful life can be (you’ll see when you read the next post) – there are these moments when it all seems hopelessly unimportant. Thank God, or better, that guy in Syria a mere 3400 years ago who allegedly wrote the oldest piece of music to date – at least of which we know, for music. One and a half year ago I wrote and recorded a song (with the title Alles) as a wedding gift for my wife Christine. Yesterday evening in a melancholic mood I cut a small non-pretentieus video clip for it from video and photo footage on May 11 2007 (our wedding day).

Hope it makes you feel as good as it did me!

Australia gone mad – Melbourne cup 2008

If you think Holland goes berzerk whenever "orange" (national soccer team) plays, then australia goes completely mad with the Melbourne Cup, the biggest horse race on the planet. The country very literally was on hold today, the joy culminating at 3PM when the race began. This time an australian horse (Viewed) and jockey (Blade Shinn) took the gold (check all results here). If this blog will allow it, you can view the race in the movie object below, if not check this movie on youtube!

Settled – definitely

Sunday evening and time for some reflection. If you’re in hurry, you might want to skip the text because there’s probably a lot coming 😀

I have been relocated to the Clayton Monash "Motor Inn", a very pleasant motel with everything a person needs: a two-person bedroom and a spare bed room for guests (my collegue Winnie was the first this weekend), a spacious living room with a bureau and couches, a bath, a kitchen with pots and pans, a plasma TV + DVD player, a railway station at reasonable walking distance, enfin: everything the first place didn’t have (not that I was too bothered by that but a bit of personal space does help you to both relax and be productive), except for friendly hosts and the fact that this place is – like the previous place – at walking distance from Clayton campus. What can I say, I’m pretty happy.

Friday I discovered a bit of the metlink municipal public transport system and took a first trip back and forth from Clayton to the center. I picked up Winnie around 6 (the first night she had booked a hotel, since when we discussed her popping over I was still in the other appartment), had a nice (but overpriced) dinner (grilled tuna) and then returned back home (yep – that’s what it feels like!) around 11:30. Yesterday I returned to Flinders street (big railway station in the south-east of the CBD) where I met Winnie again. Strolled around CBD, the Docks, had a cold beer, strolled around some more and ended up at the south bank for a pretty reasonable risotto. Below some evidence of our wanderings – needless to say, Melbourne is a very pleasant place to stroll around in.


On the train trip back home I inevitably got involved in a lively conversation with a completely pissed but very sharply dressed aussie and his wife. Interestingly, besides them, there were at least two people in seats around us who happened to know what the Bulldog and the Grasshopper are (coffeshops in Amsterdam) – and I did not bring that point up. I’m not sure if aussies could handle weed – they sure know how to drink. The occasion for the sharp dress code is "the races". Horses that is. Where in the world do you find so many people (young and old) dressed up in slick 1920s clothes (at least the women), happily loosing a truck load of money waging on horses without the slightest idea of which has a chance to win and – because of this or more likely regardless of any of it – getting totally drunk in the process. There you have a pretty concise definition of what australians are and what they do – in serious numbers.

Today we strolled around the Clayton area and the campus, which although all shops and coffee corners are closed on weekends is still a very agreeable walk. After that we gradually made our way back to Clayton railstation where I took the oppurtunity to do some shopping for my first serious attempt at living here: cooking my own meal (instead of the quite horrible microwave crap I lived on last week). As it is, my fridge and cupboard are now full of fresh veggies (from a veggie supermarket with about every conceivable piece a fruit, herb and vegitable growing somewhere on this planet), chicken and minced meat (for the ridiculous price of 5 dollars, which is 2,5 euro) and potato’s, pasta and dried herbs. And of course some beer, cereals, soy milk, nutbars and – what can I do – a bottle of 12 year old Glenlivet). I made a wonderful vegitable/chicken/potato meal with lots of herbs (basil and oregano and tomato’s and was so content with myself that I cleaned up and did the dishes. Ha!

 As far as i’m concerned tomorrow I’m going to make a head start with my research – first an overview journal paper on state estimation / data fusion. I look forward to it!
