Can you enter the Schengen area with a UK visa? How long should it take to refresh a Developer Sandbox? I refreshed a Developer Sandbox, and almost 24 hours it is still "pending". Is this normal? Are there any actions I can take to speed up the process? When I created the Sandbox it took barely more than 10 minutes to create.  Thanks, Adrian Is it possible to change he/she (he or she) in a sentence into one word? For instance: When a student comes in, ask him or her to... What is port forwarding and what is it used for? There are a lot of questions on , but there doesn't seem to be one that clearly states what it is and what it's used for. So:   What is port forwarding? What is it used for, and why would I need it? Why are two universal objects isomorphic? Calculate first difference by group in R Torsion elements of a group aren't necessarily a subgroup In a question from an exam in an undergraduate group theory course, we were asked to prove or disprove that the set of all Torsion elements of a group is necessarily a subgroup.  I knew that the set of Torsion elements is closed under the inverse operation, but was later told that it is not closed under multiplication, therefore disproving the claim. However, I couldn't find any examples of a group $G$ and two elements $a,b$ such that both $a$ and $b$ have a finite order, but $ab$ doesn't. I know that for this to happen $G$ must be an infinite and non-Abelian group, but still couldn't find a valid example.   What are some examples of groups/elements fulfilling the aforementioned property? Not all files are visible over MTP I have LG L5 (e610 model) device with Cyanogenmod 10. When I connect the phone to a computer with Linux (I have mtpfs installed), I can see both internal storage and the SD card.  However when I navigate inside them, I can't see some of the files.  For example, if I open file manager app on the phone, I can see several files in the Internal storage/Notifications directory, however the directory on the computer only shows one of those files.  If I switch USB connection type to PTP (camera) - as OS X doesn't support MTP natively - Image Capture sees the phone as a camera, however it can only see about a third of all the images present on the phone.  I don't have a Windows machine to try, but I suspect the results would be similar.  I tried upgrading Cyanogenmod to the latest nightly, clearing and reinstalling it - same results.  Any idea as to what is going on?  How can I make all files appear on the host computer? Clipboard for copying and pasting files in command line? In Bash, suppose I visit a directory, and then another directory. I would like to copy a file from the first directory to the second directory, but without specifying the long pathnames of them. Is it possible?   My temporary solution is to use /tmp as a temporary place to store a copy of the file. cp myfile /tmp when I am in the first directory, and then cp /tmp/myfile . when I am in the second directory. But I may check if the file will overwrite anything in /tmp.  Is there something similar to a clipboard for copying and pasting a file? WOL - Wake On Lan over internet How is (p ∧ q ∧ ¬r) ∨ (p ∧ ¬q ∧ ¬r) ≡ (p ∧ ¬r) ∨ (¬q ∧ q)? Is it really distributive property? Uncheck checkboxes by changing particular checkbox state I have custom fields in contacts form named checkbox1__c, checkbox11__c, checkbox12__c, checkbox13__c.  When I check checkbox1__c then I want checkbox11__c,  checkbox12__c,  checkbox13__c to be unchecked.  When I unchecked checkbox1__c then I want checkbox11__c, checkbox12__c, checkbox13__c to be checked.  Is there any way to do this by using validation-rules? If not no way to this by validation-rules, then what is the best way to do this? I want to make someone a present by subscribing for him to a mathematical journal. (It should appear every month or every two months). The contents should be comprehensible to an undergraduate in mathematics, and be about a broad selection of topics (for example not only analysis).   I expect the content to be something like proposing interesting problems and then giving solutions with some references for further study. Are there some famous journals you could suggest me? Is the Ministry of Magic unable to detect illegal time-tampering? Since Hermione already admitted that they were breaking the Law. Would it be safe to conclude that the Ministry cannot instantly (by magic) detect illegal time-tampering?  (Both before and during the events of Prisoner of Azkaban.)     “Hermione,” said Harry suddenly, “what if we — we just run in    there and grab Pettigrew —”       “No!” said Hermione in a terrified whisper. “Don’t you understand?    We’re breaking one of the most important wizarding laws!    Nobody’s supposed to change time, nobody! You heard Dumbledore,    if we’re seen —”       — Prisoner of Azkaban, chapter 21 (Hermione’s Secret) change citation style ( [1-4] to [1]-[4], and [5, 8-9] to [5], [8]-[9] ) with natbib? I have spent a whole day trying to solve the following problem. Please help if you know how to do this.  I am using natbib (\usepackage[sort&amp;compress,square,comma]{natbib}), and my current citation style looks like [1-4], [5, 8-9].  What is the easiest way to change the citation style to [1]-[4] and [5],[8]-[9]? Incorrectly answered 'No' to "Any previous visa refusals..." on a UK Standard Visitor visa application. How can I fix my mistake? As I show below, typical alien depictions include an elongated, pale face, two dark elliptical eyes, and a small mouth.  Who first used this design for an alien?  Where does this design come from?
