Comment Re:Considering how few boys graduate at ALL (Score 1, Informative) 355

If you genuinely think this then you haven't been paying attention. The primary point of feminism has been historically to put men and women on equal footing and give them equal opportunities. The fields in question, computer science, are actually a case in point: the percentage of females in computer related fields actually used to be higher. It actually dropped with the rise of the personal computer which was advertised as a thing for young boys. See http://www.npr.org/blogs/money/2014/10/21/357629765/when-women-stopped-coding and it still hasn't gotten to the point it was in the 1980s. And when skilled people, of any gender, aren't going to the fields where their skills can be most useful, we all suffer.

Yes, there are some radical feminists who have some very bad ideas or end goals, but that's going to occur in any political movement. Paying attention to outliers is not helpful. If someone had said in 1970 that the movement for racial equality's primary objective was to sabotage white people that would be the exact same sort of thing, and it would have the exact same things wrong with it.

Comment The idea is interesting but I'm not convinced. (Score 1) 219

The idea here is interesting but I'm not convinced for three reasons: first, the fact that massive staffs are used to plan out their days isn't necessary great evidence that it really is difficult: that could be administrative bloat. Second, for much of a trip to Mars days will end up looking very much like each other until one is actually on planet. They won't be doing much in the way of experiments on the way to Mars. Third of all, a 20-30 minute delay will not really create that many problems with getting plans from Earth unless one is in some sort of emergency situation.

Comment Re:Dark Matter? (Score 1) 142

Possible, but there's no reason to particularly locate that hypothesis. In this conext, the specific particle which may be a tachyon is the electron neutrino. We already know that standard estimates of neutrino mass make it extremely unlikely that the standard three types of neutrinos are anywhere near enough mass to be more than about 5% of dark matter, and that's likely a vast overestimate. As to there being some other particles that are dark matter that happen to be tachyons- possible, but why even identify the hypothesis as relevant? The primary evidence for dark matter is gravitational: whether particles are tachyons or tardyons we expect their interaction with gravity to behave about the same.

Comment Difficult to reconcile with SN 1987A (Score 4, Insightful) 142

The primary difficulty here is going to be the same data that was really tought to reconcile with in the OPERA experiment, namely the data from SN 1987A.

In that supernova (the first observed in 1987 hence the name), the supernova was close enough that we were actually able to detect the neutrinos from it. The neutrinos arrived about three hours before the light from the supernova. But that's not evidence for faster than light neutrinos, since one actually expects this to happen. In the standard way of viewing things, the neutrinos move very very close to the speed of light, but during a core-collapse supernova like SN 1987A, the neutrinos are produced in the core at the beginning of the process. They then flee the star without interacting with the matter, whereas the light produced in the core is slowed down by all the matter in the way, so the neutrinos get a few hours head start.

The problem for FTL neutrinos is that if the neutrions were even a tiny bit faster than the speed of light they should have arrived much much earlier. This is strong evidence against FTL neutrinos. In the paper in question, he mentions SN 1987A in the context of testing his hypothesis in an alternate way using a supernova and the exact distribution of the neutrinos from one but doesn't discuss anywhere I can see the more basic issue of the neutrinos arriving at close to the same time as the light.

Comment "We didn't do it. Shutup or we'll do it again." (Score 2, Insightful) 153

North Korea's response seems to be "We didn't do it. Shutup or we'll do it again." See for example the quotes listed at http://www.cnn.com/2014/12/21/world/asia/north-korea-us-sony/index.html?hpt=hp_c2. After saying that they didn't do it, North Korea then says that:

The DPRK has already launched the toughest counteraction. Nothing is more serious miscalculation than guessing that just a single movie production company is the target of this counteraction. Our target is all the citadels of the U.S. imperialists who earned the bitterest grudge of all Koreans.

They then go on to say that their soldiers along with the hackers in question are sharpening their bayonets. North Korea seems to want to have it both ways: claiming that they didn't do it, but wanting everyone to take their threats seriously like they did. At this point, there really shouldn't be substantial doubt that North Korea is responsible. The only question is what the proper response is.

Comment Re:Should Allah be translated to God? (Score 1) 880

That's almost the exact opposite argument than you made in your post. You really don't seem to have a coherent point here. Apparently Christians who speak Arabic are perfectly ok using the same word. If they thought that the words had different meanings then they'd try to use different words in Arabic. The fact that they don't shows that your entire claim doesn't work. You seem to be confused about whether "Allah" is a proper noun or a generic. Like the word "God" in English it is both.

Comment Re:Muslims? (Score 1) 880

I don't know what "hate site" means in general, but that's at minimum a source that has very much already decided on their bottom line http://lesswrong.com/lw/js/the_bottom_line/, which means one shoudl already take it pretty skeptically. But that list isn't very helpful for a simple reason that it just shows that there are a lot of Islamic terrorist events which isn't terribly helpful: we already know that. The question being asked is how common are they compared to terrorist events motivated by other ideologies or religious traditions.

Comment Re:Muslims? (Score 5, Informative) 880

Getting data on these issues is complicated. If one restricts to the US, then about 10% of all terrorist attacks are Islamic. See http://www.washingtonsblog.com/2013/05/muslims-only-carried-out-2-5-percent-of-terrorist-attacks-on-u-s-soil-between-1970-and-2012.html. But not only is this restricted to the US, it uses a very broad notion of what counts as terrorism. If one weighs in the US by total deaths, then Islamic terrorism swamps everything else primarily due to 9/11. Worldwide, about 70% of all terrorist attacks are by Sunni Muslims but this varies from year to year. See for example the 2011 report NCTC report http://fas.org/irp/threat/nctc2011.pdf. Again, definitional issues can move this number up or down by a lot.
