I was trying to install kde in my ubuntu 15.10.  I used the following command  sudo apt-get install kubuntu-desktop   I encountered these two errors--  The following packages have unmet dependencies:  kde-telepathy-minimal :                 Depends: kde-config-telepathy-accounts (&gt;= 15.04.0)                          but it is not going to be installed.   Now whenever I try to use apt-get it shows this error continuously.  I am unable to even remove the half installed kubuntu-desktop.

can't get placeholder attribute to work in IE using iframe Why am I getting rounded faces when combining Edge Split and Subsurf? What's going on here? I'm trying to apply a normal edge split with a subdivision to make it look high poly with good edges. But when I applied it on this model it did this. I know that taking the derivative of position with respect to time defines what we call velocity, but I've never heard of physicist going in the opposite direction with position. Is there any application for the integral of position with respect to time?  Maybe with respect to something else? Make it clearer when looking at a question if I've already voted to close it Since "" we now have the possibility to retract close votes.

Do I need a flight ticket or a flight reservation for my UK visit visa application Am compiling documents for my visa application and I read that I need to present go and return flight tickets to prove that I will return at the end of my visit. Then a while ago I got to know that I can just get a flight reservation with out buying the flight tickets because the visa application can be refused and you have already bought the tickets.  So l request to know which of the two , having a flight ticket or flight reservation is more compelling to the visa officer and more convenient me because I would buy a flight ticket and my application is refused I am pretty sure it shouldn't, but want to make sure that I am doing this correctly in a proposal that I am working on.  Should job titles like "Project Manager" ever be capitalized, and if so when?  In particular I am concerned about capitalization in sentences like this where the title refers to a specific person, not the role in general.     "The Project Manager will   evaluate the alternatives and offer a   solution."   I'm a lot more certain that it should NOT be capitalized in sentences like this.     "A project manager is the person who   manages the budget and deliverable for   a project."

Got French Schengen visa but no "VIS" after giving fingerprints I had my French Schengen visa interview 3 days ago (got the stamped visa and passport within two days, super efficient!). However there's no "VIS" written on the visa, even though I gave my fingerprints during the interview in US. I had presumed VIS would be written on the visa since I gave my fingerprints, or is it for something else? I do remember it took a while to take the fingerprints because the machine looked old and was taking a long time to read my fingerprints.  The next time I want to apply for a visa, do I need to go for an interview again just because the visa has no VIS on it? All Faces to Individual Objects I am looking for a way to take all the faces of an object and make each face it's own object.   In the image above, you'll see a basic representation of what I'm trying to accomplish. On the left is a shape with faces, all attached. On the right is the result I want, an object for each face. The project I'm working on is much more complicated than this example, so I can't select each face and separate by selection. I have over 3,000 faces to work on.

Further anonymize deleted accounts by changing the username in close/delete notices When an account is deleted, the username in the user's posts and comments is changed to a generic user&lt;userID&gt;. But the username stays the same on close and delete notifications on posts the user had voted to close / delete1. I think it shouldn't, especially for users who used their real name as their username, if they chose to distance themselves from the site and remove their accounts, it makes sense that they wouldn't really want their name plastered on close and delete notifications.   A perhaps easy way to avoid the actual username remaining visible would be to change it to the generic user&lt;userID&gt; (or anything generic enough, like "anonymous") prior to deletion, and wait a bit for the generic username to propagate all over the site. If I'm not horribly misreading , this was part of the process in the old days.   This could be automated or added as a suggestion to the .  Glaring example can be seen , where the deleted user also posted a comment where their name is properly anonymized:        1 I've seen it on close notifications and self deleted answers. I'm not sure it happens on deleted questions, or deleted answers that aren't self deletions, and I don't have a way to verify it - other than stumbling on them accidentally When can a hyphen ("-") be used, and what does it mean?

Installation of Ubuntu 16.04 blocked: cannot find hard disk I am trying to install Ubuntu 16.04 LTS on a Dell XPS 13 (9350). The laptop came with Windows 10 pre-installed. I am installing from a pendrive but I think the issue would be the same if I used e.g. a USB DVD drive.   Dude, where's my hard drive?  I am blocked because the installation program cannot find 8.6Gb of free space on my hard drive despite the fact that there are hundreds of Gb free according to Windows. Digging a bit into the problem, it seems that Ubuntu cannot see my hard disk at all.
