"People call them unicorns" because the combination of skills required is so rare, said Jonathan Goldman, who ran LinkedIn Corp.'s LNKD +0.66% data-science team that in 2007 developed the "People You May Know" button, which five years later drove more than half of the invitations on the professional-networking platform.
Employers say the ideal candidate must have more than traditional market-research skills: the ability to find patterns in millions of pieces of data streaming in from different sources, to infer from those patterns how customers behave and to write statistical models that pinpoint behavioral triggers.

Over the years I have worked on a number of replacement projects. Looking back I realize that the real motive for many of these replacements was a severe competence debt in the old system. People would claim that the old system was impossible to maintain when the real problem was that they did not understand how it worked. Yes, technical debt made things worse since the confusing code and lack of automated tests made it frustrating to understand the system....
Unfortunately, replacing a system just because the competence debt in the old one is too high is seldom a good idea. The whole project lacks meaning for the users since the new system will not give them any visible improvements....
Ironically, the process of replacing a system often forces developers to study the old system, thereby reducing competence debt in it…Read the entire post at leanway.no

I think tobacco was the only one that went down. They've given back a hundred years of price decline and they gave it back between '02 and '08, in six years. The game has changed. I suspect the game changed because of the ridiculous growth rates in China—such a large country, with 1.3 billion people using 45 percent of the coal used in the world, 50 percent of all the cement and 40 percent of all the copper. I mean these are numbers that you can't keep on rolling along without expecting something to go tilt.
Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.
