How would I find a minimum weight spanning tree for W? I installed Ubuntu on a Dell XPS 13 laptop that had Windows 10 preinstalled on it. I installed it from a USB flash drive on a partition. When I boot my computer I can only boot into Windows 10 and Ubuntu is nowhere to be seen.  If I boot into my USB then I can see that Ubuntu is installed, but I can't get to it from the BIOS boot menu. Summing data from column in the Attribute table I'm working with population data, and I have an issue when it comes to knowing the sum of a population inside the attribute table.  In my attribute table, I'd like to add all the numbers in the red box, i.e. all the numbers together from the column &quot;UN_2015_E&quot;. Is there a way to do so? When on the road as a tourist, I often do not carry a reflector of flash. Now I am at a location with very strong sunlight and I want to take a photo of a companion in front of a nice scenery or building, the classic "we have been here" photo.  With very strong sunlight however, specially at a slight angle, I either get it into the person's eyes and they squint like crazy, or they are in the shade and their whole face is black.  Please note that I do not have aspirations to take a professional photo in such circumstances, but at least something acceptable.  Is there an easy trick to deal with that? Cardinality of a totally ordered union I did not know that you could find an answer for that. However, I can only use Excel so far to do it.  How to calculate 3.6! by hand? Restore a SQL Server 2012 backup file in SQL Server 2016/2014 I have SQL Server 2012 backup files and want to restore these to SQL Server 2016/2014. Will it work?

In this book, the authors are not native speakers(they are XACT BOOK(India)), and they wrote these specific places without article "the":     -It is Taj Mahal.      -It is Tower of Pisa.   At first, I thought it's okay, but there are some pages has article "the":     -It is the Great Pyramid of Giza.      -It is the Temple of Artemis.   These sentences really make me confused. After researching, this website- - gives me some advice:     Do use the before:           names of rivers, oceans, and seas: the Nile, the Pacific          points on the globe: the Equator, the North Pole          geographical areas: the Middle East, the West     deserts, forests, gulfs, and peninsulas: the Sahara, the Persian Gulf, the Black Forest, the Iberian Peninsula      Unfortunately, I'm still not sure that adding "the" before each wonder's name is a right choice. Should I add article "the" or not? I already posted this problem in , but I'm still in vain. Show that there is no epimorphism from ($\mathbb{Q}$, +) to ($\mathbb{Z}$, +) I would like a way to mark a question in the Unanswered "my tags" page as something I'm not interested in or able to answer The /unanswered/tagged?tab=mytags page gives a list of questions from my favorite tags that are currently considered "unanswered" - they have no up voted or accepted answers. I think it's good to put them in front of me easily, but even though they have one or more tags that I'm interested in, I may not have the knowledge, ability, or interest to write an answer to them. However, they will remain on this page until someone writes an answer.  I would like to be able to dismiss questions from views, like this one, that show me interesting questions. I may choose to share them on my social media to get them views and answers, but I don't want to continually see them. Instead, I want to be able to use views like unanswered/tagged?tab=mytags as a queue of things that could use my attention. Following on from this question:   It seems all feats carry over to your new form if your new form is capable of using them (so Mounted Combatant and Inspiring leader would usually be ruled as unusable in most circumstances). But what about Tough?     Your hit point maximum increases by an amount equal to twice your   level when you gain this feat. Whenever you gain a level thereafter,   your hit point maximum increases by an additional 2 hit points.   Would this increase your maximum HP by the same amount when in the form of a rat, or brown bear? Clipped data frame clips labels? I have a large project with provincial data. The project is currently using a data driven map with a clipped data frame for the province. The issue is the data I'm trying to show is thousands of point labels within each province, and the now clipped border is clipping labels as well. How do I stop the labels from being clipped along with the data frame?  Also, I only want to show labels that are applicable to that specific province and not the neighbouring provinces. How to remove conference information from the ACM 2017 SIGCONF template? Better explanation of the common general relativity illustration (stretched sheet of fabric) When are Opportunity Attacks provoked while holding a reach and a non-reach weapon? Assume I wield a Whip in one hand and a dagger in the other.  If a creature moves from 5ft to 10ft it has technically moved out of my reach (dagger), but at the same time it is still inside my reach (whip). When does it provoke opportunity attacks from me?  I am fully aware that this would not enable me to make off-hand attacks since the whip is not a light weapon, just to cut that issue out of the question. Option to be notified when a post I downvoted is edited Prologue:  This is an effort to follow up on  which is marked as a duplicate of  highly voted and status-declined feature request (although they seem to be different, one focusing on the OP and the other on the downvoter).   My New Year's resolution was to downvote more.  So on January 3rd or so, I saw a post that was low quality, and downvoted.  Two days later, I came back to see if it was ready to be deleted or had gotten piled with downvotes, to find it with a significant positive score!  At which point, I noticed that the answer had been significantly improved.  So I retracted my downvote, changed it to an upvote, and immediately resumed my dearth of downvoting again.  I think I have a responsibility to downvote bad posts, despite that oh-so-painful -1 rep penalty.  But if I am also going to have the responsibility to follow up on every downvote I cast, I'm not going to bother. I don't want my downvote to leave a residual penalty on posts that were once low quality, and I am not going to trouble myself to keep checking up on every post I downvoted.  Can a downvoter have an option to be notified when a post they voted down was edited?  I wouldn't make this an automatic thing, because not all downvoters want it, and it isn't applicable to all cases of downvoting (although  that this should be part of the responsibility of a downvoter).  Personally, I would make this a universal toggle on-off option on the user profile page, not a question-by-question option, but I don't have strong feelings about it.
