Adult films — i.e. porn films — are also called blue films. But why are they called that?
I have data from a survey comprised of several measures that used different Likert-type scaling (4-, 5-, and 6-point scales). I would like to run a principal components analysis using the data from these measures. It seems to me that I need to transform this data in some way so that the power of all items is equivalent prior to analysis. However, I am uncertain how to proceed.
I installed the ubuntu-sdk 2 days back on my machine (12.04) and the Qt version that is installed is 5.0.2. Everything was working perfectly, but today there were some updates from the ubuntu-sdk-team, after installing which, Qt Creator does not show the Ubuntu welcome page and there is no project type for Ubuntu Touch, it's simply gone.
The default currency converter app works, and i've got a new project type called Cordovaqt.
The flip side to all of this is that, Qt Creator works with the ubuntu plugin and everything as before IF it is run via terminal. Why is this happening?

When Ramsay was in the captivity of the Stark's, he said to Sansa that Sansa is a part of him. What did he actually mean by this? Did he mean that Sansa is carrying the baby of Ramsay or is it just random words?
Is there any way that I can make rounded corners on a rectangle rendered in XNA through primitives (line-strips)? I want to make my UI a bit more fancy than it is already, and I would like the code to be flexible, without too many textures involved.
I am learning sailing on a 5m catamaran (Nacra 5). I am familiar with basic aerodynamics and the physics of the sail and keel.
We learned that when sailing closed hauled, too tight a mainsail tends to bring the boat up to the wind. And that the opposite is true for the jib. For example, one may steer up to the wind to come about, using the mainsail alone, by trimming it tight.
My question is why the trimmed mainsail in the above setup gives a larger torque.
This also seems opposed to the rule: "The more the mainsail is sheeted out the more the boat tends to come up.", as explained in http://www.sailtheory.com/mandf.html#sailsteering
To my understanding, there are several possible competing effects involved:
(1) Effects that tend to INCREASE the mainsail torque to head up:
(1A) The direction of the sail force becomes more perpendicular to the boat. This increases the heeling torque. Since heeling motion happens faster than turning, the boat will heel more. This moves the sail force out, which increases the lever arm and the torque to head up. see diagram in: http://www.sailtheory.com/mandf.html#hellingstuur
(1B) The sail force moves backwards since the sail is stretched backwards. This increases the lever arm and the torque.
(2) Effects that tend to DECREASE the mainsail torque to head up:
(2A) The direction of the sail force becomes more perpendicular to the boat. Assuming that the force is perpendicular to the sail, and that the center of rotation is between the mast and the center of force, one sees that pulling the sail in, reduces the torque to head up, as can be seen in the following diagram:
As Theta gets smaller, the torque Tau is reduced. This is opposed to what is stated in some of the answers below.
(2B) The sail force is reduced since the sail was pulled beyond its optimal angle of attack, thus losing lift and reducing torque.
(2C) Due to (2B) heeling torque is also decreased. With a similar reasoning to (1A) this decreases the lever arm and torque.
(2D) The sail force moves forward since the aft part of the sail is too flat and stalls. This shortens the lever arm and reduces torque. This is described in http://www.sailtheory.com/mandf.html#sailsteering
We know from reality that 1A+1B > 2A+2B+2C+2D. Considering heeling alone, we also know that 1A > 2C. It remains to be explained why in general this is the case.
I'm planning to visit the UK soon, and am interesting in taking myself off for walks and hikes, of varying lengths. Exactly where in the country is not fixed yet. How can I find out where it is suitable and allowed to do this? What maps are available to guide me?
If scots law/information is different, please answer for England/Wales (although there may be bonus points for an answer that also covers the rest of the UK).
I may also be interested in hiring a bike and cycling. Will I be able to do that in the same places?
This question has been asked as part of the June Bounty Bonanza, and as such, will have a bounty awarded. If there are really good answers in place by the time the bounty is awarded, the bounty value may increase
I want to configure my Drupal site in order to make commenting easy to motivate visitors.
Which modules can I use to create a better commenting experience for visitors?
For example, if a visitor comments on the website and then another time if he wants to comment the name/e-mail/website fields are automatically filled is a good thing.
Or comment with Twitter/Facebook/Linkedin account is another ease.
Note: I don't want to use third party commenting solutions such as Disqus. I want to use Drupal core comment system.
A mishna on Meila 11a talks about money that a nazarite set aside for his offerings; if he died before completing the term and had set money aside specifically for the sin-offering, those coins are dropped into the Dead Sea. (I know that this is a specific case of a more-general rule.) This led me to wonder how that was done: were the coins dropped in individually, for each person as the case came up, or collected and dumped en masse (after some amount of time perhaps, or when there are "enough" to be worth the effort, like when we collect papers for burial)? I then found two possibly-contradictory ideas: on the one hand, some speculate that a large collection found by archaeologists was from this kind of disposal, but on the other hand, I'm told that Rashi on Pesachim 28a says there was a concern that people would collect them. (According to the latter view, the Dead Sea was chosen because ships didn't go there, not necessarily for its corrosive properties.)
If there is a concern that people will go diving for them, it would make sense to dump them individually, as the cases come up, not in large volumes, to reduce the profitability of that. On the other hand, that's more of a hassle to manage, and raises the risk of the money being used instead of destroyed.
How was this done? Was each payment dumped individually, or was money collected until there was "enough"?
Lately we have been noticing issues with the Debug Logs.
Missing debug lines
Sometimes either CODE_UNIT_STARTED or CODE_UNIT_FINISHED goes missing. For example The log shows when a trigger finished running but omits its starting point. There are no skipped lines (due to large log size) in between the 2 expected events. We are also seeing debug statements that don't match their sequence in the code. For example if "debug 1" and "debug 2" are written back to back, sometimes we only see "debug 2".
Missing debug logs
Sometimes there are no logs even though the proper window is set for the user.
Nonoperational trace flag overrides
I know this is a duplicate of my earlier post referenced above but for completeness I'm including it here again. Basically my logs in a namespaced DE org are now filled with ENTERING_MANAGED_PKG statements.
Does anyone have any hacks to offer? Some have suggested that Apex Profiling may be responsible for at least some of the issues but I have it set to None.
I have been developing on SFDC for 7 years now, and I am slowly starting to lose confidence in it. Debugging is the very basic of any development platform and without it you simply can't take it seriously.
