Peach picking

The weather was great and therefore Karen and I decided to pick peaches nearby on a farm in Crozet, VA. It's a lot of fun and one can eat as many peaches "on the job" as you can. For economists, this is a nice example of real-life decreasing marginal utility: after 5 peaches one barely has an interest in another one :-)

Cookies and What-you-see-is-what-you-get

Jean Piaget noticed in 1920 that children often fail to distinguish between perception of an object and the object's actual properties. When a two-year old child sees her playmate leave the room, and then sees and adult remove a cookie from a cookie jar and hide it in a drawer, she expects that her playmate will later look for the cookie in the drawer - despite the fact that her playmate was not in the room when the adult moved the cookie to the drawer from the jar. Why? Because the two-year old child knows the cookie is in the drawer and thus expects that everyone else knows this as well. Without a distinction between things in the world and things in the mind, the child cannot understand how different minds can contain different things. Piaget concluded that "the child is a realist in its thought" and that "its progress consists in riddling itself of this initial realism." Children come to realize that perceptions are merely points of view, that what they see is not necessarily what there is, and that two people may thus have different perceptions of or beliefs about the same thing.

Q: Are you aware of different perceptions?

Open Source & The Cathedral

Nicholas Carr distinguishes between the 'Cathedral' and 'Bazaar' model. The former is the traditional model 'from the ground up' for development of product and services and the later describes the 'Open Source' movement. The question is whether the Bazaar model can be used for everything like it was used for the development of Linux.

Carr claims that the bazaar model is most and only useful for actions that are divisible and require little coordination effort. Debugging is a typical tasks that can be parallelized. Like in an easter egg hunt, the bazaar model works best if there is a simple task 'find the easter eggs' and there are many independent participants.

The cathedral method is preferred for other tasks, e.g. product development from the ground up. It would be very challenging to develop a product in this way with so many participants. It should be noted, however, that even in the Linux project there was a tight advisory crowd that coordinated the debugging efforts of all the people. This ensured that the overall project moved into the right direction forward. As a side note, Wikipedia, another bazaar style project, does not have this kind of authority which makes it prone to prone to delays and errors.

In short, peer production works best for:

1. Routine tasks that can be pursued simultaneously by a big crowd

2. Projects in which labor is donated and can be parallelized.

3. Projects that are not totally egalitarian or democratic.

Five Easy Pieces

Building true teams

The scientists sought to compare successful teams with less successful ones, and figure out exactly how they differed in composition. They focused on a few academic fields, defining successful teams as those whose papers were most frequently cited. They also looked at the annals of Broadway musicals over the past century and studied how the mix of composers, lyricists, directors and so forth correlated with the success of the production, measured in terms of the number of weeks a production ran before closing.

What they found was that the most successful teams did two things right. First, they attracted a mixture of experienced people and those who were newcomers to whichever field they were in. That's not surprising—the need for fresh blood has long been recognized as an important ingredient in success. The second criterion, though, was far less obvious. What successful teams had in common was at least a few experienced members who had never collaborated with each other. "People have a tendency to want to work with their friends—people they've worked with before," says Luis Amaral, a physicist at Northwestern and a coauthor. "That's exactly the wrong thing to do."

What is strategy

If you can touch it it's tactics, if you can't it's strategy.

Quote: Tiha von Ghyczy

City for a newspaper

Usually newspaper "circle" around cities. There's the Boston globe, Washington Post, New York Times, etc. The founder of the Wall Street Journal created a 'city of interest' for his paper. He targets readers that are all somewhat interested in business and economic issues.

That's a classic example for changing "the rules of the game". Which rules can you change?

Ants & Algorithms

My friend Martin told me about the Ant algorithm that is used to optimize connections on micro chips. It's a fun approach to solve complex issues like the traveling salesmen riddle:

In the real world, ants (initially) wander randomly, and upon finding food return to their colony while laying down pheromone trails. If other ants find such a path, they are likely not to keep travelling at random, but to instead follow the trail, returning and reinforcing it if they eventually find food (see Ant communication and behavior).

Over time, however, the pheromone trail starts to evaporate, thus reducing its attractive strength. The more time it takes for an ant to travel down the path and back again, the more time the pheromones have to evaporate. A short path, by comparison, gets marched over faster, and thus the pheromone density remains high as it is laid on the path as fast as it can evaporate. Pheromone evaporation has also the advantage of avoiding the convergence to a locally optimal solution. If there were no evaporation at all, the paths chosen by the first ants would tend to be excessively attractive to the following ones. In that case, the exploration of the solution space would be constrained.

Thus, when one ant finds a good (short, in other words) path from the colony to a food source, other ants are more likely to follow that path, and positive feedback eventually leaves all the ants following a single path. The idea of the ant colony algorithm is to mimic this behavior with "simulated ants" walking around the graph representing the problem to solve.

Ant colony optimization algorithms have been used to produce near-optimal solutions to the travelling salesman problem. They have an advantage over simulated annealing and genetic algorithm approaches when the graph may change dynamically; the ant colony algorithm can be run continuously and adapt to changes in real time. This is of interest in network routing and urban transportation systems.

Strawberries in Virginia

Karen and I went strawberry picking with Ashley and Fred in Crozet just 15 miles from Charlottesville. According the "honor code" I checked with the farm in advance (no kidding!) what the corporate policy is regarding eating while being at work. As you can see it's allowed! It's a lot of fun and believe it or not, those berries taste much better than at Harris Teeter!

The diploma

After two years at Darden I'm taking home much more than the MBA diploma. I keep with me an absolutely incredible professional and personal experience and the friendship to many amazing friends. Those characters have enriched my life tremendously and I'm looking forward to continue the rest of my life with them being part of it.

Learned helplessness

Learned helplessness is a psychological condition in which an animal has learned to believe that it is helpless. It has come to believe that it has no control over its situation and that whatever it does is futile. As a result, the animal will stay passive in the face of an unpleasant, harmful or damaging situation, even when it does actually have the power to change its circumstances. Learned helplessness theory is the view that depression results from a perceived lack of control over the events in one's life, which may result from prior exposure to (actually or apparently) uncontrollable negative events.

Salt the organization

1) Use old staff - only "salt" a little bit with own people
2) This transfers culture
3) Bring people early on together (in seminars, training, leadership development sessions)
