Book Review: The Sleepwalkers, How Europe Went to War in 1914
Sleepwalkers is a very dense history but very well written. The text is scholarly and does not explain the contextual history for the reader. The reader is expected to be familiar with the basics of the period. A novice will... Continue reading

There are probably biological differences. There is a long history of widespread milk-borne death and illness before pasteurization. Bread doesn't have a history like that.
The bread environment is probably hostile to the pathogenic bacteria. The acid dry environment of hard cheeses is one reason that raw milk hard cheeses have not had problems. Yeast might emit toxins that inhibit bacterial growth. Cooking is certainly part of this. The lower temperatures of pasteurization are enough to kill the pathogens. Partially cooked bread might be hot enough to kill them.

Proper Statistics
I was reminded at the FDA summit of proper statistical evaluation methodology. The study was one looking at the impact of color calibration of monitors on the accuracy and speed of dermatology diagnosis. Step one, they measured the inherent variability... Continue reading

Two book reviews
First, Iron Curtain by Anne Applebaum. This is a very good history of how the Soviet Union took over Eastern Europe in the years 1944 to 1956. It really only covers East Germany, Poland, and Hungary in any detail. The... Continue reading

Software Risk (and the end of the world)
When I was in college I made some book shelves from boards and cider blocks rescued from a dumpster. In my first job after college, I worked with a guy who made custom crafted bookshelves that sold for tens of... Continue reading

Chromebook C7 Experience (It's the right choice)
After using it for about two months and taking it on some travel, I've decided that this is a suitable machine. It's a bit awkward traveling with two computers, but having both machines available is worth it. My original impressions... Continue reading

Eat oysters, fight global warming
Recent travel inspired me to do a little research. Oysters are a form of carbon sequestration. They accomplish the same kind of permanent carbon storage as technology costing millions. The oyster shell is calcium carbonate (mostly) and lasts for many... Continue reading

The politicians' perspective

Advanced manufacturing
On Sunday, the New York Times published article on advanced manufacturing. It's accurate enough, but the tone is very misleading. It takes the tone "Wow, this is all new and different". The factory he describes fits the manufacturing environment I... Continue reading
