This took a little while to get of the ground (the guy in the movie is the person who setup business ideas, it looks like he is in the passenger's seat):
I am going to try to put a (hopefully original) idea or drawing online everyday.

A wonderful present: SINAAS , Juliana & Bernhard 25th Anniversary tile
My former colleagues at verKoopwinkel, which is owned by Sinaas B.V. gave me this tile. Sinaas stands for Samen Is Niet Alleen, Altijd Samen. And Sinaas is also close to sinaasappel or oranges like in the tree on the tile. Use translate.google.com if you want the English texts.

Laura Mappin visualisation
I think Laura Mappin is great.
She sent me this comment and diagram:
I checked out your blog and am very curious about your pricing discussions. I’m a small business person new to pricing products – making my way into a new business after years in hi-tech. I’ve looked at my issues from so many angles and have changed my approach several times. There’s nothing cast in stone about it, it seems to me.
As I read your latest post of your email exchange with Dieter Brandes, I saw this drawing in my head as possibly the barest kernel you guys are discussing.
It’s not about making a margin. It’s about bringing in a certain amount of money (pink) selling whatever products (type of product, end price, % profit per item or type of item, quantity of product sold is immaterial to this discussion). So, it can be acceptable to have a product (E) that you sell a lot of, make very little off each one, but the sales of E overall adds significantly to what you bring in. (guess I shouldn’t have colored it pink ;)

Anyway – just curious if this is one of the points you’re trying to make.
I suspect trying to make every product be sold at the same % profit makes it easier to run the store ;) Also, this method requires maybe more rigorous cost calculations to make sure they’re representative?
Thanks for your blog thoughts – and your comments.

Wolframalpha reports non existant hill in the Netherlands

Click here for Wolram|Alpha's answer to "Mountains Holland".
The Polaris Hill 335 meters high near The Hague does not exist. The notion that it was first climbed in 1959 is also a bit silly.
And where is the other half of the province of Flevoland ?

Craigslist CEO : Crooks will be caught

The chief executive of Craigslist has a message for people who try to use the popular Internet advertising site to commit crimes: You're going to get caught.
Violent crimes linked to Craigslist ads in Boston and Minnesota have made headlines, but CEO Jim Buckmaster said Wednesday the site is an "extremely unsafe venue for criminal activity because you're virtually guaranteeing that you're going to get caught."
"That's been the case with nearly every serious violent crime that's been connected with the site," Buckmaster said in a telephone interview from San Francisco, where Craiglist is based. "There's an electronic trail leading to yourself. So don't use Craigslist for crime unless you want to go to jail."
A Minnesota man was sentenced to life in prison without the possibility of parole this month for the 2007 slaying of Katherine Ann Olson, who answered a phony ad he posted for a baby sitter.
And this week, a 23-year-old Boston University medical student was charged with robbing women who advertised erotic services on Craigslist and killing one of them, Julissa Brisman.
"We were shocked and saddened to learn that a horrific crime like this had any connection to the use of Craigslist, and our hearts went out to the family and friends of Julissa Brisman," Buckmaster said.
Philip Markoff, 23, is accused in the death of Brisman, a masseuse from New York City who was found dead in the doorway of her upscale hotel room after being bashed in the head and shot three times. Markoff also is accused of robbing and tying up another woman, and police have said there could be more victims.
Defense attorney John Salsberg has said Markoff isn't guilty.
Buckmaster said the attention Craigslist has received because of crimes linked to it is partly a function of how heavily the site is used and the relative newness of the Internet.
"There are 50 million people using the site every month, and the site has facilitated billions of human interactions over its history. Compared to human society as a whole the risks of Craigslist are low, but they're not zero," he said.
Buckmaster declined to say much about how Craigslist is cooperating with authorities investigating the Boston case but said, "We make ourselves 100 percent available to them and provide them with any and all information we have that they may request."
Law enforcement officials generally ask that Craigslist not comment on what it's doing in specific cases, he said.
Buckmaster defended Craigslist's inclusion of the "erotic services" classification on its sites. He said users requested it so those ads would be posted there, where users can avoid them, instead of being scattered among other ad categories. He also insisted that illegal activity is "absolutely not welcome there."
He said Craigslist will donate 100 percent of its net revenues from those ads to charities, under an agreement announced last November with 40 state attorneys general, though he said figures aren't available yet.
Craigslist's city sites include tips on personal safety and avoiding scams and fraud. Buckmaster said the Minnesota and Boston cases provide an opportunity to remind people that it makes sense when meeting someone found through an online ad to take the same kinds of precautions they should take offline.
"Anytime you're going to meet for the first time choose a public place where there are other people around. ... Consider bringing a friend along. Let someone know where you're going to be and when you'll be returning. Take your cell phone along. Trust your instincts and report suspicious activities to authorities," he said.
Craigslist founder Craig Newmark will attend a benefit concert in Minnesota on May 3 for a scholarship fund at St. Olaf College in memory of Olson. The 24-year-old was slain by Michael John Anderson, 20, who used a Craigslist ad to lure her to his home in the Minneapolis suburb of Savage.
Buckmaster said Craigslist officials were inspired by the Olson family's efforts to keep the focus of the case on Katherine Olson's life and what she meant to her family and friends.
"When there was an opportunity for Craigslist to participate in some way, that was something we were excited about doing," he said.

Beachmonsters / Strandbeest visitable in Holland ?
LABATORY YPENBURG
The lab consists of a sandpit measuring 30x15 meter, a cabin, a large sea container and lots willow trees. There is the bone yard as well. Usually there are only one or two animals living at one time. As soon as the development of an animal is at its end, I declare it extinct and I push it onto the bone yard. The animals there can be seen as the fossils of extinct species. Exposure to sun and rain causes the tubes to fade, making these appear more bonelike with time. The sandpit is the pre-heaven for the beach animals. They are not yet ready to survive the real beach. I still have to train them. Usually I take them out once a year to the real beach to let them get a taste of their natural environment.

Correlation

from: http://xkcd.com/552/
PS ; from Freakanomics blog (read a few days after I first placed this cartoon on this blog)"
Correlation vs. Causality: The Cartoon Version
By STEVEN D. LEVITT
I don’t know why, but academic economists just love to use cartoons in their presentations. I would guess that one out of three academic seminars includes a cartoon, and if it is a plenary talk, a cartoon is virtually guaranteed.
I don’t have anything specifically against cartoons, but to the best of my recollection, I have never in my life included one in my presentation, or linked to one from this blog — until today.
My former student Hays Golden sent me the following cartoon from xkcd.com, and it is so appropriate given the classes I have taught this term, that I can’t control my economist urges. I have no choice but to post it here on the blog:

A replacement for Google Answers ?

...
1. Ask questions to Mahalo Answers via Twitter
-----------------------------------------------
--> How it works: You can ask a question to Mahalo Answers by putting @answers at the start of a twitter message (i.e. "@answers Find x in this diagram" Our community answers the questions and you get tweets back when there are new answers.
--> How you can help: First, please try asking a really good questions to @answers. Second, you can follow the madness of the @Answers Twitter account here: http://www.twitter.com/answers -- feel free to unsubscribe from it if it's too much (you don't have to subscribe to it in order to ask questions).
--> Bottom Line: We're getting 50% of our questions from Twitter now and this system allows users to participate without ever visiting Mahalo Answers (http://www.mahalo.com/answers ).
2. One dollar tip on all Mahalo Answers Questions
-----------------------------------------------
--> How it works: Every question on Mahalo Answers now has a "Mahalo Dollar" tip on it. This means the best answer to any question wins a Mahalo Dollar as a tip. Mahalo Dollars are a virutal currency that can be exchanged for real dollars less a 25% handling fee (i.e. our profit, accounting and paypal fees).
--> How you can help: Tell a friend who likes to work from home to check it out. It's not a big money, but if someone were to answer 10 to 20 questions a day in their spare time they might make an extra $250-500 bucks a month (which is *exactly* how Weblogs, Inc. started out: folks making $100-300 bucks a month turned into folks making $500 to $2,500 a month).
--> Bottom Line: We're trying to build a virtual currency around knowledge. Imagine if each good edit to the wikipedia made .10, every good blog post you did made $1.50 and each front page submission to Digg made $2--that's my vision of the future. Content creators making small amounts of money for contributing better an better quality content. Micropayments for microcontributions (we already have a system for macrocontributions obviously... jobs!)
Please let me know what you think.
all the best,
Jason

The man in the fleece above was one of the other locals, besides myself, who was helping out at the crash site before the rescue services arrived in force.
Via Twitter all sorts of TV & newspapers wanted my story. Ansgar John, who was driving nearby, jumped out of his car and ran to help the survivors. "Some of the people that had left the plane were lying on the ground, a lot of them had back injuries, and some were in shock," he told ABC News.

Supporting Mass-Customization at Adidas
Whole story here Streamlining the Supply Chain to Support Mass-Customization
Since 2006, Alison Page has been leading a team focused on streamlining the supply chain for the custom manufacturing operation. As Adidas has perfected and experimented with front-end technology to enhance the custom shoe design experience, Alison and her team were streamlining the custom manufacturing process. "We're constantly tuning our infrastructure for speed, flexibility, and lot size one; for example, being able to download orders to the factory daily vs. periodically was a major change to our production operation." Distribution costs are also a challenge, Alison explained. The costs of air freight are high, yet customers want fast delivery. Raw material management is a big challenge. Supporting true mass customization requires internal change management.

June 2005 The Economist "Biggest bubble -> biggest bust?"

They got it right. In June 2005 ( here ), why is everybody so surprised now ? :It is not going to be pretty. How the current housing boom ends could decide the course of the entire world economy over the next few years.
This boom is unprecedented in terms of both the number of countries involved and the record size of house-price gains. Measured by the increase in asset values over the past five years, the global housing boom is the biggest financial bubble in history (see article). The bigger the boom, the bigger the eventual bust. …
