I have a strange hard drive error that is happening about once per second. Googling I see that people are suggesting: 1. a bad SATA cable, or 2. a bad PSU. Does anyone have any experience with this? Seems very unlikely that a bad SATA cable can actually happen.

My new 1,5 TB ext4 Hard Disk makes mysterious noises and fails to read and write. But not always. Sometimes it just works. But then I get those following errors.

What is Ruby's double-colon `::`? Dragging layer into new file changes its size Let's say I have a file that's 4'x12' and represents a space on an actual wall. I want to open certain files (of different sizes) and drag each file into the large file in order to arrange the images correctly on the computer before physically hanging the framed finals.  When I drag a new image into the larger file, the new image's size and the size of its copy don't match. That is, Say I drag an 8x10 into the large file, well on the large file (trying to control size with guides and rulers) the new image is some other size, but not the right one.   What am I doing wrong? How do I make sure that when I click and drag the new image that it will be properly represented? I have some HTML menus, which I show completely when a user clicks on the head of these menus. I would like to hide these elements when the user clicks outside the menus' area.  Is something like this possible with jQuery?  $("#menuscontainer").clickOutsideThisElement(function() {     // Hide the menus }); Why are lamps and mesh lights not illuminating anything? There are several techniques to do a 3 point lighting system.   How do you properly light a scene while using mesh planes as emission light sources?   I'm following , however despite setting up planes to act a lighting sources, the scene is still very dark.      Actual Blender file here: MAC OS for Intel based PCs I have an Intel dual core PC with 4GB of RAM and Graphics card. For on of my student Assignment I need to install Latest possible MAC OS on my system as a secondary OS.  Like on boot it asks me that which OS i want to boot with Win 8.1 or Mac Os..  I searched on the internet and found two conflicting opinion some people said there are few MAC OS Version which can be directly installed on Intel PCs some says there aren't?   I am here to get rid of the confusion that is an official latest possible MAC OS version for Intel based PCs? If not what are my options if I want to run MAC OS on my PC.   Please not that Virtualization options won’t work for me, it has to be working as full OS not an os inside another. Reasons why not to update an Ubuntu version to a newer/older kernel version I frequently prefer to look for questions on superuser .    I have never been able to determine how these search results are ordered.  Typically, search results are returned in order of relevance and the search help says they are "weighted heavily towards question title matches", but in this case, you would think that the search would order them based on whatever tab is currently selected (newest, hot, active)?  I ordinarily never stray outside of 'newest', but it's clear the results are not sorted by age. How is the determinant related to the inverse of matrix? What punctuation should follow after a list introduced by a colon? The whole department: John, Jeff, Jean, and the accountant [?] were thrown into jail. Why aren't all the badges shown on the track menu? I like using the 'Track Badges' menu on my profile a lot (I know what you're going to say, I just have a knack for these things), but I keep noticing something a bit unusual.  Many of the Badges featured on the actual list do not get featured on this menu. For example, I've been hoping to be able to track progress for the Pundit badge (ten comments with score of five or more), but it doesn't show up in the menu.  Why not? How do I remove code duplication between similar const and non-const member functions? Let's say I have the following class X where I want to return access to an internal member:  class Z {     // details };  class X {     std::vector&lt;Z&gt; vecZ;  public:     Z&amp; Z(size_t index)     {         // massive amounts of code for validating index          Z&amp; ret = vecZ[index];          // even more code for determining that the Z instance         // at index is *exactly* the right sort of Z (a process         // which involves calculating leap years in which         // religious holidays fall on Tuesdays for         // the next thousand years or so)          return ret;     }     const Z&amp; Z(size_t index) const     {         // identical to non-const X::Z(), except printed in         // a lighter shade of gray since         // we're running low on toner by this point     } };   The two member functions X::Z() and X::Z() const have identical code inside the braces.  This is duplicate code and can cause maintenance problems for long functions with complex logic.    Is there a way to avoid this code duplication? I use HD Tune to measure performance of the hard drive.  The tests typically take 2-3 minutes and the transfer rate of a regular hard drive decreases dramatically as the test comes to a close.    However, the SSD drive performance stays the same over (pic below) the life of the test.  This happens on all my computers.  Why is that? Issue with 'StringVar' in Python Program What's the intuition behind the identities $\cos(z)= \cosh(iz)$ and $\sin(z)=-i\sinh(iz)$? I'm trying to understand in an intuitive manner the relationship between the circular and hyperbolic functions in the complex plane, i.e.:  $$\cos(z)= \cosh(iz)$$ $$\sin(z)=-i\sinh(iz)$$  where $z$ is a complex number.  From a geometric point of view, what I understand is that cos is the composition of a rotation through $\frac{\pi}{2}$, followed by cosh, and sin is the composition of a rotation through $\frac{\pi}{2}$, followed by sinh, followed by a rotation through $-\frac{\pi}{2}$ (where sin, cos, sinh, cosh are defined as complex functions).  Where does this connection come from? Is there some way it can be visualized in terms of complex mappings? (I'm not asking for a proof of the identities, I already know one). Children’s books, one in space setting, the other in a jungle I compile my project with VIsual Studio 2005 Express Edition, and get this linking error. Can anyone suggest how to solve that?
