Submission + - SPAM: Safety Truck Displays Road Ahead

Llamalarity writes: Technology is cooler than coon poop, from the article, "Samsung has created a tractor-trailer with a video feed that displays the road ahead on the back of the trailer. The idea is to help other motorists determine if it’s safe to pass the truck."

There are few if any missing moon rocks. Other than the small ones gifted to politicians... While there may be many missing samples these are extremely tiny and often intended to be consumed by whatever test they were being subjected to. Nothing to be concerned about here, lots of other things do deserve our attention.

"Who eats Chinese chestnuts?" Me for one, but yes true American chestnuts are noticeably sweeter. Though sadly much smaller... You neighbor should contact the American Chestnut Foundation and see if they might want to add his trees genome to their program. Which is to produce a blight resistant 15/16 American chestnut to restore back into the eastern forests. These folks have been quietly working on this for over 25 years and are very close to achieving their primary goal.

Don't forget each of these techniques vary by the quality of the hardware as well as it's sensitivity and spatial relation to the source of the stimulus . If I put a cheap mic in a high traffic area ( office / street ) with an addition of white noise (salt) and generation of keys limited to traffic hours you could get a decent seed. Make a large number of salted seeds when you can and salt again per host.

While you are right that using these methods for realtime key generation could be predictable generating many when the data is rich is still a better than most approach.

With a Word document, you first need to *find* the document, and make sure you have the latest copy. The one on your hard drive might be 6 weeks out of date. The one in your e-mail folder for that project might be a week or two old, the one on the server a day or two old. There might be a copy your co-worker is editing right now.

Revision control software can help, but I've got an aversion to using CVS/SVN-style revision control for binary files. Yes, it can work, but the software was created for text, and you still need to let others know if you want to make changes, so they don't try to at the same time, or you'll have conflicts that can't be resolved since it's binary. And you need to have a local copy of the workspace just to get that one file. In my case, the svn client is on Linux/Sun machines, but I need to edit on a Windows PC. It's just a pain all around.

From that standpoint, wikis are so much easier. We use them to write up tutorials and theory-of-operation types of documents and the like. Too bad my company wants all official documentation (product specs, designs specs, etc.) to be in Word.

You have a control group (one type of food) and a variable group (the other type). The single independent variable is the difference between the two; in this case, the (binary-valued) variable is "organically grown". Nutritional value is an outcome; it isn't an independent variable. There is nothing in scientific methodology that says you can't measure multiple outcomes within the same study; you could measure nutritional value *and* toxic effects *and* effect on occurrence of antibiotic-resistant bacterial strains within a single study that has the same independent variable, if you have the resources and interest to do so.

Perhaps you were only trying to say that, since it was a meta-study, they were constrained by the nature of the previous studies in existence. That may be the case (or maybe not), but that's a resource constraint, not a methodological constraint. And the way your original statement was phrased has me convinced you were referring to method.
