An older article from The Atlantic, on
Management Myths. Telling comment from the viewpoint of Scientific Management
the science of handling pig iron is so great and amounts to so much that it is impossible for the man who is best suited to this type of work to understand the principles of this science, or even to work in accordance with these principles, without the aid of a man better educated than he is.
Worth a read if only for the historical perspective.

After installing Ruby 1.9.2 from source on Centos, a few days later got a strange error from rake and gem commands
# gem list
<internal:lib/rubygems/custom_require>:29:in `require': No such file or directory - ?? (Errno::ENOENT)
from <internal:lib/rubygems/custom_require>:29:in `require'
from /usr/bin/gem:8:in `<main>'
Found a fix for this at Ruby Forum Beware prelink and compiling ruby from source. The problem seems to be prelink corrupts ruby, so just need to ban prelink from touching the ruby executables and libraries. Need to ban
/etc/prelink.conf. by adding the line
to the conf file. Hopefully someone else will find this in the search engines and not have to reinstall ruby too many times (but once it has occurred you will need to reinstall to fix the corruption).

Not sure what it is about the magazine, but it seem to be incapable of reporting the implications of actions. A stunning example of this comes from their Babbage Blog reporting on the delays in the acceptance of the reports that CO2 is warming the planet…
Erring on the side of extra caution is not a bad idea, and various efforts are underway to develop, corroborate and better to underpin the work on temperature records that has been done to date.
Erring on the side of extra caution for climate change would suggest that we take steps to reduce CO2 emissions, not that we do yet more studies on whether the planet is warming and how fast. We already have the warming data, and it does not look good. “One sure bet is that this decade will be the warmestâ€ on record – James Hansen
