Off to stretch the legs again this weekend. Not quite as exciting as the Brass Monkey Biv trip … but surprisingly I was pretty tired by the end of the day… not quite sure why really as it should have been fine!

It was here:

View Larger Topographic Map

Just a nice cruisey loop on a track.. didn’t see another soul – which was surprising as it’s (apparently) the only loop track in Arthurs Pass… though our tramping book is a little out of date so maybe that has changed.

These trees were interesting…

I’m no botanist.. but the ground was pretty clear beneath them (little bush).. so I’m assuming they’re some sort of old growth trees? No idea.. feel free to comment if you do know. Feel free to comment if you don’t know. Generally, just feel free to comment. Unless you’re a spammer… then you can go away and not comment. Right.. back to task..

Where we camped on Friday night was probably the worst case of sandflies I’ve ever experienced.. the air was just *thick* with them. We got in and out of the tent as fast as possible.. but still had to kill about 200 of the things that got inside in the seconds the fly was open. Nasty.

All up a nice tramp… but there are probably other ones to do before this one will be repeated … especially with the sandflies!

So… Malc who helped me rebuild Snowpool last year in Ruby on Rails organised this years RailsCamp. It’s the first conference of this kind I’ve been to. A Geek conference. It’s called a Camp because the idea is that there’s no internet…

Malc organised it at Cheeseman Ski Field. I’m afraid I don’t have any pictures… and, while I did feel a little out of my depth for quite a bit of it (mistake of sitting at the table with the people from the States!), it was fun. Every evening (for some reason) Werewolf is played. Definitely one of my favourite games to play. I was outclassed though.. there were some good players about.

So yes, it was fun to be there, I should have open-sourced Snowpool (maybe next year… – or, at least, after this season)… I do enjoy working in Ruby on Rails (it is _so_ nice to work with)… but yes, definitely at the bottom of the pecking order :)

Oh – and this was pretty cool

This weekend we managed to get away from ChCh and off tramping. It was certainly one of the more adventurous tramps that I’ve done, and certainly just with Maaike. It was off to a place I’d heard quite a bit about – Brass Monkey Biv. It’s here

We parked the van at the St. James carpark (and hoped we’d see it on return – never like parking there). Up the ridge, along the ridge – following the route in the map above. We made one, slightly wrong route choice and went down a gully that was a little steeper than it needed to be (see route in red in pic below)

Still, it wasn’t too bad, and we picked our way carefully. Still, not optimum.

It was about a 6 1/2 hour walk for us to make the hut. Mist was threatening to come in all the time, but our navigation was good (no tracks to follow this time!), and we had a tent anyway just in case everything went to pot. If you look very carefully (and imaginatively) you can see the biv in the middle of this pic – it was a welcome sight.

Lovely place to spend an evening. The mist was coming in all the time though, and we woke up to pretty thick fog. It cleared up enough, and I think our navigation would have been up to the challenge anyway, but it does make me think about getting a GPS and an PLB (personal locator beacon – ping a satellite and they send a chopper your way). I’m all for personal responsibility, but I’m also for stacking the odds in your favour.

Anyway, mist.

And then it was out to the road where we had to wait about 5 minutes before getting a lift from some venture scouts coming back from Nelson!! Fantastic – saved a 10 km uphill walk.

Also, here is a short video which really won’t mean much to anyone outside of ChCh, but it’s a skit on the earthquake recovery efforts… The jacket is the “Parka of Power” that our Mayor (Bok Parker) wears all the time… and it’s evil and makes you power hungry it seems.

He’s talking about a glider which is coming – a reference to Richy McCaw the NZ All Blacks captain who arrives at the end of the skit (and can walk on water.. but that’s a whole different story!)
Really really good skit – hadn’t laughed so much in ages.

So. This is a picture of Lenny – the sockbear.

Lenny lives in The Netherlands with Maaike’s sister… and this year, in conjunction with Maaike, he set me a series of challenges. Starting a week before my birthday.. I’ll admit that I loved 85% of it… but was surprised how much I learned about how badly I deal with having odd problems thrown at me.. and asking friends for help! I do neither of these things well it seems!. On with the tasks..

Task 1: whanau is important
a) please draw Maaike’s whakapapa, 4 generations back.
b) you need to collect some more information about 3 people (at least one on paternal side and one on maternal side)
– what is their DOB?
– what kind of person are they or were they?
– how do/did they make a living?
c) you can collect bonus points if you do 5 generations…

It took a couple of days, and I’d not realised that Whakapapa goes forward as well as backwards in genealogy.. at least according to Maaike (final arbiter on all things!).

Next were some climbing questions… that I found pretty tricksy..

Once that was complete it was (finally!) onto a question that I actually found doable on my own and didn’t have to ask help for :) I loved it. That’s not to take from the other questions.. It just being my area I quite enjoyed it.

First of all.. I had to work out what the question was!…

A long time ago before we had computers that were really much
smarter than us, computer programs and data were stored using
paper tape.

The tape reader was made up of a toothed drive wheel, a light
source and 8 light sensors.

As the tape progressed on the drive wheel, the light would
shine through holes in the tape. If the sensor on the other side
detected the light, a binary ‘1’ bit would be registered. Where
there was no hole, a binary ‘0’ bit would be registered.

This can be shown in a bit of ASCII art using the message “Hello
World”, and how it might be encoded:

Holes for toothed drive wheel

———–

After quicky extracting the punch cards into actual ASCII.. it was (overkill) but a fun half hour working out the Ruby code to give me the answer..
here’s the binary and the ruby follows…

class String
def convert_base(from, to)
self.to_i(from).to_s(to)
end
end

test = File.open(‘binary.txt’)
output = “”
while line = test.gets
output

The answer to task 3 was “Garage” … which was where the next clue was. I had to work out what the following meant:

Which led me to a place well known to me (admittedly first guess was out by ~50km…) where I got task 5

This was another fun but tricky one.. had to work out the amount of cash it would be if you covered NZ in $1 coins. I was out through excitement by about a factor of 100 the first time… but quickly corrected (yes, discovered I get quite excited and jump to an answer without thoroughly checking my workings.. I’d be a rubbish scientist!) ($639,429,962,458,034 was the number I got, but I measured the coin as 22mm… I didn’t look it up to see it was 22.5mm… so was probably out by a few billion)

Then it was onto a questionnaire..oh.. and I had to bake for my colleagues (that Lenny is a hard taskmaster!)

Then I got a picture of some cat food… and had to go round to the cats I’d looked after for some friends to solve the final puzzle. Well, final but one..

I have misplaced the last puzzle (which was an excellent one)… had to do some social engineering.. well, work out the sorts of places that Lenny might have gone to.. Will put it up in a bit!

All in all… lots of fun (and some frustration too.. which was silly on my behalf!). Thanks to all who helped contribute to the puzzles – and to the answers (I’d have been lost without you all), and thanks especially of course to Lenny. You’re a hard taskmaster! but a good one :)
