South-East-Asia being battered by storms, earthquakes and tsunamies

In the Last week most south-east-asian countries on the pasific coasts have been battered by the typhoons Ketsana and Parma. Next to that Indonesia has been hit by 2 major eartquakes (7.6 and 6.8) and Samoa by a tsunami.

The Philippines first got hit by typhoon Ketsana. Resulting in by 295 death and 39 still missing. And leaving over 400.000 people homeless.
Ketsana was shortly followed by typhoon Parma, resulting in: 17 deaths, 61,600 metric tons of rice destroyed, 74,373 hectares of rice-growing areas and 6,000 tons of corn, fruits and vegetables. With windspeeds of 195kph to 230kph.
Total financial damages up to 96 milion USD.

After the Philippines, Ketsana struck Vietnam. This resulted in 159 deaths, 112 milion USD in crop losses, 180.000 destroyed homes and 50.000 hectares of agricultural land destroyed. There also where miles of railroad tracks washed away or destroyed.

(on average, vietnam gets 6.4 typhoons a year, this is the 9th and there some more months in the season).

Following Vietnam, Ketsana hit Cambodia and Laos.

In Cambodia the death-toll topped 17 and 1519 people lost their homes. Cambodia lost 50.000 of rice paddies, 40km of road was destroyed and 160 irrigation systems.

In Laos 24 people died and 135 people are still missing. 37.500 are homeless due to the storm. The water of the sekong river had risen 13-15 meters, arround 14 villages have been flooded.

In most affected areas in these countries the water levels haven’t dropped yet or are even still rising. Support organisations are working hard on saving and supporting people, but due to the damages to infrastructure this has turned out quite difficult.

In the mean time,  in Samoa and Tonga where hit my a big tsunami of about 7.5m in height which swept land inwards upto 1.5 km. In total arround 170 people died and thousands where turned homeless.

Next to all this, Sumatra (Indonesia) got hit by 2 earthquakes, one of a 7.6 and one of 6.8 magnitude. arround 1600 people did not survive the quake, but some hunderds more are still at risk due to famine. arround 38.000 homes where damaged, leaving thousands of people homeless.

This leaves the south-east-asian area quite battered and the typhoon season isn’t over yet for the comming months. Typhoons Parma and Super Typhoon Melor are still in the area. Threatening Japans and the Philipines.

Science and… Cookies.

I have this desire to make double chocolate chip cookies. And I want to make the perfect one. Yesterday I decided to give it all another try. The results are as follows:

Experiment #1:

I decide to make a mix of 200 gram self-raising flour(flour+bakingsoda), 100 gram cacao, 150grams of sugar,  200 grams of butter (margerine), .1 egg and about 100grams of chocolate chips (70%).

Attempt #1: Horriby  dry, can’t say why. but not fit for consumption.

Attempt #2: Added 50grams of butter, the mixture got a lot more sticky, results where less dry but nothing specia.

Attempt #3: by now the ammount of dough shrinked considerably but I decided to add another egg. Result: quite eggy cake like chocolate chip cookies. not bad at all. Ofcourse at this point I’ve got no idea what the right ammounts are

Attempt #4: Added more flour as number #3 was really sticky, result: more cookie like cookies. Also not bad, but a bit bitter. And not a clue on how to reproduce. I fail at science.

Experiment #2:

Attempt #1: 200 grams of self-raising flour, 150 grams of granulated sugar, 250 grams of butter, 100 grams of cacao, 2 eggs and 100 grams of chocolate chips (70%). Result: Good structure, but not very tasty, still a bit dry and bitterish.

Attempt #2: Added another 100 grams of sugar. Result: Sweet. :) Structure is quite good although they stay fluid quite long after taking them out of the oven.

Money and Wheels

I like re-inventing wheels, and doing research a little less. Re-Inventing wheels gives someone the possibility to look at a certain concept from his personal view, without infecting himself too much with existing research. Besides that it’s quite educational and just plain fun. :)

After contemplating the idea arround money last time, I decided to do a little research into time-sharing systems and ideas (as some also referred me to). My sugestion of using time as a currency had, as I already hinted on, some complications.

My time as a someone with certain skills has different value for different people. For instance, one might not want to ‘hire’ me as a carpenter, since I’ll be a lot slower then anyone with experient or schooling. This results in that the value people have for someones time is related to their skills/experience and the task at hand. Now this might not be a big problem, as finding someone with the right skills might not be too hard. It’s a matter of matching up people with tasks.

A bigger problem though is, how I value my time for someone. I might love to help out a good friend of mine with some work, but I’d rather not spend much time for/with the anoying prick arround the corner. This results in me giving a certain value to the ‘credits’ I would get for my time. Which since they are personal and depending on complex variables (social groups, my mood, the weather, etc), become rather hard to predict.

Which brings us to a general problem with currency/money.

Unless you can find a currency which is based on something that has a  static value for -anyone-, value is going to be personal and fluctuating. Even with food or nutrients this problem remains, we might -need- a minial set of specific basic nutrients to survive. But what we want is a lot more complex, I like food, I like to differentiate it, try different forms of it. This results in a complext carier for a currency. Just as bad/good as any other.

In a way our current monetary system is a religous one, we believe it has a -certain- value, and this is why it has one. Kind of like douglas adamsartifical god‘.  We value items and services, and in a way this is what money represents. But how we value these, or how much value we accredit them, differs. It changes per subject, per person and over time. This makes it very hard to predict or define what the value of the currency is, kind of like predicting the future. And although people have tried this, I don’t think anyone succeeded yet.

It comes down to predicting what each individual wants, how much they want it, and how that is going to change. And this for everyone who is using the currency. Now one could create a ‘hack’ arround this by making a lot of assumptions. Taking into account some group dynamics, general marketing effects, one could asume their will be some big groups which would atleast somewhat agree on how much they would like a certain thing. And since things take time to move arround in large groups, with enough information of where things are flowing between what, one could even make some predictions on how it’s going to change.

So yeah, it gets pretty vague, but it’s something. Ofcourse respect for any individual in a scheme like this is out of the question, unless you start grouping individualists into sets with certain common trades. If you can’t dump down, or simplify the information, you’ve got nothing.

Now some would asume from this, ok so money is essentially worthless, if it has any value it’s highly irregular and unpredictable. So why not just get rid it?

Money does have certain important, or atleast very usefull trades or properties. Because it abstracts the values we have for things, it makes it possible to devide, share and save it. It becomes easier to calculate things on, to share resources or goals. Getting someone to make you a meal with exotic ingredients (like a nice curry), gets a lot easier with money. Or even just making it yourself. I’d need rice, which comes from asia, paprika, potatoes, other nice veggies and some spices. Ofcourse ecologically one would want ‘local food’, but rice doesn’t grow here very well, and I like curries. Money makes it easier to share the transport of rice and veggies with other people, without me knowing them (although I might not mind that). It makes it easier to calculate the transport costs, costs for people involved in producing the products and probably more things, into one price, one value. Even though this ‘value’ might be incorrect, it is a value, where else there would be none. It makes it more concrete for me on how to get a nice curry. I have an idea on what the value of my time is to atleast certain people, and I can have an idea what part of that value can be traded to get a nice curry.

The problem with this ofcourse is, that these ‘values’ can be hopelessly incorrect. The question then is, does that matter?

I think it would depends on someones goal. If your goal is getting efficient trade systems for specific groups of people, probably not. If you want want a fair world, it would matter a lot. Then you want to value people’s work and lives correctly. And that is what it comes down to.

The problem with fairness though, is that money is a highly inadequate tool, which is most likely to express the value incorrectly. The ‘problem’ then is, that trade becomes a highly personal ordeal. Which becomes impossible to abstract. Any abstraction would actually de-personalise the transaction, making the value-judgement less precise. And any transaction would represent a social properties, afterall, personal relations gets highly mixed up in value assesments.

Now the final question that remains for me is, how do I get myself a ‘fair’ curry? I supose one not all that horrible solution would be befriending myself with a captain who would take me to india where I can befriend this chef who would be willing to make me a nice curry. Maybe not very ‘time efficient’, but I don’t think I would mind. :)

SculptureSystem5

Regarding the last post, Edmund made his blog entry: http://maxwelldemon.wordpress.com/2009/04/25/building-mathematics-sculpture-system-5/

It bit more wordy then my post, and a bit more pictures. So more information :).

Crowdsourcing mathematical art.

So I’m currently staying in Iceland for a bit, and in the past days we build a big deltahedron from wood and metal rods. Last night we constructed it with a bunch of people in a vulcano on Vestmannaeyjar. Is was quite a lot of fun to build it, paint it and assemble it.

This all happened in the context of the fablab on Vestmannaeyjar. The idea and concept was done by Smari and Edmund, the design was made by local kids at the fablab. The final choice for the design was done in the vulcano by all the participants.


More pictures of the construction will follow.

Theatervoorstelling van Momo

Het is al weer een lange tijd terug dat ik het boek ‘Momo en de tijdspaarders‘ van Michael Ende heb gelezen. Volgens mij is het nog langer terug dat ik naar het theater ben geweest, schandalig eigenlijk.

Nu lees ik zelden boeken meer dan 1x (al is momo daar 1 van), maar het theater blijf ik toch wel leuk vinden. En doe ik eigenlijk dus veel te weinig. binnenkort weer eens rondkijken.

De voorstelling zelf was erg goed, natuurlijk mis je een aantal onderdelen, maar het is niet makkelijk zo’n dik boek op het toneel te krijgen. Ze hebben de kern van het verhaal ook erg goed overgebracht, mooi gespeeld en erg spannend.
Ik zowel het boek als de voorstelling, erg aanraden:

Dan Gilbert: Why are we happy? Why aren’t we happy?

Just watched this intresting talk on happiness by Dan Gilbert, I do think he has a point :)

New HealthMatrix Release.

Finally found some time to work more on healthmatrix and build a release.

Version 0.99, not yet a 1.0 but getting close. And I have got it running stable in a production enviroment. I just think I can make it more efficient, better documentation and package it more neatly.

I’m also still pondering if the library should go on CPAN or not.

To get the to point, the major changes since the last 0.92 release:

  • Completely new execution deamon, hmexecd instead of hmatrixd. Doesn’t crash anymore, better abbility to handle load (don’t execute everything at once :). Uses  Paralell::Prefork for starting instances which look for jobs.
  • Improved Web-interface, now shows you if any cells/tests are past their due date. The border of a cell changes color accordingly. And Javascript alerts when there is a database error.
  • Template support
  • Easy installer for the bin/script part.
  • Some code clean-ups (mainly in the execution bit)

Still on the todo list:

  • Munin Limit Check support (maybe even graphs, but don’t get any hopes ;)
  • Nagios support, probably
  • Alert History (so you can see if something went wrong in the past)
  • Cleaner packaging + cleaner debs.
  • Neater error reporting in the GUI (javascript alerts are easy but anoying)
  • Clean up of the GUI code, it works fine, but could be more efficient/streamlines I think.

Do give it a try if you like, and let me know what you think, especially if you have any problems.

Food Not Bombs

Last saturday (20080124), I went to help out with food not bombs Leiden. A fun idea and since leiden has some great people organising this I decided to help out for a day.

I think we had a great day, we had 2 pots of soup to share and a ‘bakfiets’ full of free stuf. We didn’t finish the second pot because it was getting rather cold. We still had quite a bit happy ‘customers’ though :)

We had a wonderful tomato/carrot/garlic soup with lots of veggies and some a load of bread. All made from food that supermarkets and veggishops didn’t want to sell anymore.

I also took some pictures which are featured below:
