I need to know whether using short URLs to back-link to pages affects your website ranking in the Google search results.
When you have a link from lets say twitter that is t.co/foo that links back to your website how does that effect SEO and how do the major search engines handle Shortened URLs?
What do you call someone who solves puzzles? What is a term or name for someone who is very adept at solving puzzles or situations that require though processing and logic.   I ran across , however this only deals with crossword puzzles. I'm looking for something that could be applied on a broader sense. Does "It snowed hard Monday" require an "on"? I came across an English learner writing     It snowed hard Monday.   After saying that it didn't snow on Friday and Saturday.  It didn't quite feel right to me.  I'd be okay with     It snowed hard.   or     It snowed Monday.   Is it okay for there to be two things ("hard" and "Monday") modifying the snowing without an "on" breaking things up a bit? Is there any standard that covers the portability of running a command after variable assignment on the same line?  APPLE="cider" echo hi   How portable is something like that? Where will it work and where won't it?   Also: my shell scripts start with #!/bin/sh if that makes any difference. How can I get my graphics card to be recognized in System Info? I am new to Linux/Ubuntu. I installed Ubuntu 11.10 on my Lenovo IdeaPad y510.   System info says    Graphics: unknown.   Driver: unknown,   Experience: Standard.   What should I do to use all my laptop hardware components to work properly with Ubuntu? Screenshot: How will people upgrade from 12.10 to later releases after 13.04 is EOL? Suspend process without killing it So I've got a persistent program running in the background. Killing it just causes it to restart with a different PID. I'd like to suspend it (put it to sleep without actually killing it). Does kill -9 do this? If not, how should this be done? Why is the mean function in Gaussian Process uninteresting? Crash adding comment What is the maximum number of downvotes a question can have I was just wondering what the maximum number of down votes a question can have before it is removed from StackOverflow. Subdivision surface modifier problem Hello!   I've recently started learning Blender and faced one problem.  After applying subdivision surface modifier I have plenty of extra faces. I've watched some teaching videos and I suppose additional faces shouldn't be added. Is it OK ? How to avoid this problem if it isn't. How do I find out a name of class that created an instance of an object in Python if the function I am doing this from is the base class of which the class of the instance has been derived?  Was thinking maybe  might have helped me out here, but it doesn't seem to give me what I want. And short of parsing the __class__ member, I'm not sure how to get at this information. What is the best choice for .NET inter-process communication? Should I use Named Pipes, or .NET Remoting to communicate with a running process on my machine? Which way should arrows point in a collapsible accordion? Left/down … down/up? Expected value of a non-negative random variable Using a variable in a SELECT statement? public static void handleCaseComment(CaseComment caseComment) {    User[] users = [SELECT LastName FROM User WHERE Id = caseComment.CreatedById LIMIT 1]; }   This gives me the following error:  unexpected token: 'caseComment.CreatedById'   How do I use the value of the variable caseComment.CreatedById in a SELECT statement? Diamond moderators  . In the second section from the top—entitled &quot;Ask questions, get answers, no distractions&quot;—that takes us to an opportunity to select one of a page full of questions from the site as the example question used on the about page. The selections currently available on physics are a little idiosyncratic. Is there some rhyme or reason to these? I suppose that we want a good example question to:  Be accessible to the intended audience (perhaps even to the newest and most naive person in that audience) Be judged at least decent by the community (positive score) Have more than one answer which are also judged acceptable (again positive score)  What else? How does a question end up on the list? Switches needed in an n-location multiway switching system we can construct a two location multiway switching system with two 3-way switches:    They also teach us how to perform three location multiway switching with two 3-way switches and one 4-way switch:    Is it possible to make a similar system (three locations, all able to switch the light in any situation) with only three 3-way switches?   What can be said in general about the switches needed to make an n-location multiway switching system? Which is correct?     How much is the two fares?      How much are the two fares? Why $x^{p^n}-x+1$ is irreducible in ${\mathbb{F}_p}$ only when $n=1$ or $n=p=2$ I have a question, I think it concerns with field theory.     Why the polynomial $$x^{p^n}-x+1$$ is irreducible in ${\mathbb{F}_p}$ only when $n=1$ or $n=p=2$?   Thanks in advance. It bothers me for several days. During the Time War why didn't the Daleks blow up at least one TARDIS while in the Time Vortex? From the Cracks in time and space story arc it's known that if a TARDIS is blown up (possibly while in the Time Vortex) it rips creation itself apart. Also, from the Stolen Earth / Journey's End we learn the Daleks' masterplan which is subjugating creation itself via destroying it with the Reality Bomb (unfading Z-neutrino energy radiation).  In the Last Great Time War all sorts of temporal weapons were used and it's known that Daleks have the ability of time travel as well. Why didn't they use the Time Vortex back then to win the war once and for all via detonating a TARDIS while inside?
