Spain Visa Extension I'm from India. I applied for a business visa to Spain for 90 days. I got the Visa approved with Multiple visits. But it's been approved only for 30 days. I need to be there for another 1 month for my Business trip. Why did this happen and could I extend my Visa after reaching Barcelona?
Is it possible to extend a tourist Schengen visa (12 more days)? My daughter applied at the Italian Consulate in Philadelphia, and they gave her two entries for 20 days (we thought it was for 20 days each entry). She was in Italy 12 days, then went to England for 1 week and flew to Venice to take a 10-day cruise. She couldn't make it because they said she has only 8 remaining days, but she still has a land tour already paid this week.  What can she do? Can she extend the Schengen visa for 12 more days? Right now, she is in Madrid, but next week she has to fly from Barcelona to Paris to start with the tour. What would happen if she decides to take the tour with the expired visa? She is a US permanent resident.
How to find a 4D vector perpendicular to 3 other 4D vectors? In 3 dimensions it is possible to find a vector c (one of infinitely many) perpendicular to two vectors a and b using the cross product. Is there any way of extending this to 4 dimensions, i.e. given three vectors a, b, and c finding a vector d perpendicular to all of them?  I realize that this can be done by solving the equation system:  dot(a, d) = 0 dot(b, d) = 0 dot(c, d) = 0   and imposing an additional constraint, for instance setting the length of d to or one of its components to 1, but is there a way of doing this that does not involve solving an equation system? How do I take great HDR photos of moving objects? By moving objects, I mean cities with cars, ocean with moving water, malls with people moving by.  I tried it on moving people and had noticeable ghosting, using bracketed shots at + and - 2ev.  What's the basic technique on getting sharp looking HDR photos in areas that are moving? I'm assuming it's not bracketed shots but a single shot with exposure editing? Finding the limit $\lim \limits_{n \to \infty}\ (\cos \frac x 2 \cdot\cos \frac x 4\cdot \cos \frac x 8\cdots \cos \frac x {2^n}) $ Is there a way to format a UTC time into any arbitrary string format I want in java?  Basically I was thinking of having some class take the timestamp and I pass it is string telling it how I want it formated, and it returns the formatted string for me.  Is there a way to do this? How do I apply a gradient across multiple objects in Illustrator? I have two separate objects that I have applied gradient fill to.  The gradient fill seems to only apply to the objects as individuals. I tried grouping the shapes, but that doesn't seem to change the gradient.    How do I get one gradient to cover all my shapes? Terminal command 'login' fails with error message Coming from Mac OS X, there is a possibility for every ordinary user to open Terminal and type in 'login' to change to a different user account.  When I do this with Ubuntu, it provides the following error message:  login: Cannot possibly work without effective root   Is there any way to remedy this?  Which file do I need to edit and with what to enable the use of this command (even for a standard user)? Theme Activate Hook Is it acceptable to nest parentheses? Is it acceptable to nest parentheses (for example, if I (meaning myself) write like this)? How can the median number of sexual partners be 6.1 and 3.6? Median number of female sexual partners in lifetime, for men 25-44 years of age, 2006-2008: 6.1  Wouldn't it only be able to be x.5 or x.0? How is light affected by gravity? I am able to produce a standard length \sim with a tiny S above it, but I would like the \sim tilde to be longer (maybe one and half times as wide as a capital letter).  Any tips on how to change the width/length of \sim? Multiple returns from a function What role-playing games should I pick for an absolute beginner group? How do you reverse a string in place in C or C++? How do I make groups in 2.8? In the Blender Guru Donut tutorial he made a sprinkle for a donut. He copied that sprinkle and made a smaller version of it. He Shift selected both and made a group with the shortcut Ctrl+G. When I do the same it assigns both sprinkles into a collection. I have read that the layer system is redone completely. So when I make a group out of the two objects, is it the same as a group and where can I see that group? Monitoring contents of files/directories? Covariance of a variable and a linear combination of other variables Let $X,A,B,C,D$ be time-series variables and the covariance between any two pairs of these are known.  Suppose we want to find $\textrm{cov}(X,aA + bB + cC + dD)$, where $a,b,c,d$ are constants.  Is there any way of doing this without expanding out $E[(X-E[X])(aA+......)]$? Change bookmark depth I want all bookmarks after "Anhang" (appendix) to be a level deeper, but I need them to be \chapter{} for the right numbering.  I write a scrbook document and that's what I got:    Is it possible to change the depth of the chapter to act like a section in the bookmarks?

If Dominic Cooper was playing Howard Stark Senior (grandfather of Tony Stark) then it is fine, but if he was playing Howard Stark (father of Tony Stark) then after 70 years he should be around 90 or above.  Tony Stark, his son, should be 60 to 70 years.  Is that possible?  Tony doesn't look 70 years in The Avengers. Windows 10: Keyboard type rate extremely slow after boot I have upgraded my computer using a core i5 2500K from Windows 7 x64 to WIndows 10 x64, and the whole system runs fast and reliable, with one exception: after booting from SSD, which takes only about 10 seconds, my keyboard is really slow for the first 1 or 2 minutes right after booting. "Slow" means that when I start notepad, and type some characters, it takes a second for each character to appear on screen. Everything else is fast, including mouse movement, starting programs, only keyboard input is that slow. After 1 to 2 minutes, the keyboard suddenly behaves normally again.  This happens with every kind of keyboard I connect, no matter if I use the legacy PS/2 adapter, or USB.  Does anybody have any idea what might be the cause of this strange behaviour?
