Comment Re:Its not Hands Free though... (Score 1) 330

Nope. I thought so as well, because that's what the statement in their press materials for it indicated to me. But the truth is it looks like the nag is based on a torque sensor or something on the steering wheel, so it only really nags you when it's going around curves above some threshold. There are videos of people filming their commute where they spend most of the time without their hands on the wheel.

Comment Only one fatal crash (Score 1) 297

The summary is incorrect. Only one of the 3 crashes had any fatalities. And so far as I'm aware is the only one yet to have confirmed that autopilot was engaged at the time of the accident. The second two accidents the drivers indicated they were using autopilot, but Tesla has not been able to confirm that yet (or at least has not publicly confirmed it).

None of the links in the summary even support the claim that there have been two fatalities.

Comment Issue is likely overstated (Score 5, Informative) 95

The paper has been available as a preprint for awhile now, and my lab has discussed it internally and I've also paid attention to outside coverage. The key issue that the paper reports is that false positive rates are two high for most existing software WHEN using a specific type of test under a specific set of conditions. They show that voxelwise familywise error (FWE) correction actually seems to work reasonably or even conservatively. Cluster level FWE correction (looking for groups of voxels that are active) fails when using a very liberal cluster-defining threshold, but works reasonably well when using a more stringent cluster defining threshold. It also says nothing about the performance of another very common correction method that is frequently used in fMRI studies (false discovery rate or FDR).

I'm not really sure how extensive the group of findings that these issues actually affect is, but it's certainly not 40,000 as is claimed in the paper's significance section. Many of the earlier papers (and even more recent) likely used uncorrected statistical tests, so are suspect for entirely different reasons from this issue. Of the ones that use correction, the findings in this paper only call into question the results for those that are using FWE cluster correction with a cluster defining threshold that is too liberal (likely > 0.001, the paper's findings suggest that at 0.001 the familywise error rate is in the ballpark of the desired 5%). Those using a cluster defining threshold of p=0.001 or lower are likely fine, and those using a different correction method like FDR are unknown as to my knowledge there isn't currently any similar paper on that correction method.

You can also check out this technical report by some other big names in imaging that basically says that this result is known and expected for overly liberal cluster defining thresholds:

Though as one of the questions during the briefing asked, they don't actually know the mass. They're pretty much guessing based on the size by using the distribution of a smaller pool of past planets that they do have mass estimates for.

From the caption for figure 4 from their presentation: "While its mass and composition are not yet determined, previous research suggests that planets the size of Kepler-452b have a better than even chance of being rocky."

Production of nanoparticle titanium dioxide is definitely hazardous. Titanium dioxide dust, present during production, is a possible carcinogen. Nanoparticle titanium dioxide has also been shown to cause genetic damage in mice. That said, I don't think there's evidence that the nanoparticles or powder present in paint pigment and sunscreen, for example, actually cause adverse effects in humans to this point, so it's unclear whether these coatings would be a concern or not.

Or, based on the timer going on the livestream now, they were streaming. But there was no apparent link from either the front page or yesterday's or today's story about watching it live.

That was essentially their support response to me when I recently tried to use Google Wallet. A particular feature was not showing up in the app. After a week of back and forth with their support the response was that my versions of Android and Google Wallet were too old and unsupported. Despite it being the version of Google Wallet I had just downloaded, and with no mention anywhere in their online help that the particular feature wasn't available in some versions.

Except that they usually don't deliver on Saturday, so ordering on Thursday means you won't get it until Monday. And ordering on Friday evening, Saturday, or Sunday means it doesn't show up until Wednesday because it gets processed as if it were a Monday order. Considering how poor their shipping has been for me and a few others I've talked to over the past 6-10 months, I definitely would not be renewing if the price goes up pretty much at all. I never really use the streaming service, because the selection and ease of use on my devices is inferior to Netflix, so if their shipping gets any worse, I don't think it'll even be worth $79/year.

I can't tell if you're trying to be funny or not. The person reporting on his experiences is one of the developers of Aaaaaculus! which is essentially an Oculus compatible version of AaaaaAAaaaAAAaaAAAAaAAAAA!!!. In addition, they've worked on several sequels and ports of that game with the original developers.

It does however stipulate that the device can't display "a television broadcast or video signal that produces entertainment or business applications." So a cell phone is definitely out unless: (A) The equipment has an interlock device that, when the motor vehicle is driven, disables the equipment for all uses except as a visual display as described in paragraphs (1) to (4), inclusive. (B) The equipment is designed, operated, and configured in a manner that prevents the driver of the motor vehicle from viewing the television broadcast or video signal while operating the vehicle in a safe and reasonable manner.
