In addition to what others said about the FSF discouraging the LGPL, it is also not allowed to statically link LGPL code to non-(L)GPL closed code. You can only link dynamically unless you provide full source.

Nonetheless, statically linking with LGPL libraries in the form of uClibc is _extremely_ common in commercial devices running uClinux. Without providing any way to relink. Forbidden, but ignored.

Clarification. Chebyshev's inequality is not going to help you with distributions that have no mean or standard deviation. Note also that the standard deviation mentioned in Chebyshev's inequality is the *population* standard deviation, and NOT the *sample* standard deviation.

Careful. Chebyshev's inequality doesn't help you if you are sampling from a physical process with a Cauchy distribution. Be careful not to confuse the *sample* standard deviation with the *population* standard deviation. The former always exists. The latter is what you use with Chebyshev's inequality... *if* it exists. In the case of a Cauchy distribution, your sample standard deviation would mislead you into thinking that the probability to fall outside N sample standard deviations had some particular bound that it did not have.

I hope he has more examples than just the temperature (no, I didn't RTFA). For the temperature in a day, most people are satisfied with the minimum and maximum, and don't need any more complicated measure. The MAD would actually be LESS informative for temperatures within a day...

He's rather requesting the people start using a different statistical measure of spread, the mean *absolute* deviation, rather than the square root of the mean *squared* deviation (the standard deviation). I'm not familiar enough with it's particular characteristics to say whether or not this would be an improvement in any rigorous sense, but I'd be surprised if it were. So "Get bent." is probably still the right attitude.

I know several people who have left high energy physics to become data scientists. Nobody in HEP calls themselves a "data scientist", but that's (some of) what we do anyway. It's just analysis of very large data sets. Unlike in the life sciences, both HEP and many commercial / industrial environments have sufficiently large data sets that very complex questions can be asked and answered. You can never have "enough data" -- if you think you have "enough data", then you aren't asking hard enough questions.

The interplanetary medium can carry sound waves. Of course, it is moving faster than the local speed of sound outward from the sun (the solar wind). So if you shouted really loud from the ISS, someone in the asteroid belt might be able to hear you. But not the other way around.

Possible, although unlikely. The -CDM model does an astonishingly good job of modeling the observed universe. But, that doesn't mean it is right.

In the case of aether, people didn't stop investigating it until a) experiments that should have observed no matter what saw no evidence of it and b) another theory that agreed with this new data came along.

People who trot out the tired old "dark matter is just like aether!" line typically do so while patting themselves on the back for their cleverness, while neglecting the above.

If there isn't WIMP dark matter, or even isn't dark matter at all, then we'll find out. That's how science works.
