I've done a clean install of 18.04 and I can't open desktop folders, not even the desktop trash can. Anybody else had this issue? I click on the desktop folders (double click) and nothing happens.  Strange enough, I can open  them when using Nautilus and going to home\stackinator\desktop\ or whatever the path is (can't remember at this point). I will be attending a summer school which will last 10 days.  I want to know: for applying for a Schengen visa, is the purpose of my trip considered as touristic or study? Problems with pie charts There seems to be in increasing discussion about pie charts.   The main arguments against it seem to be:   Area is perceived with less power than length. Pie charts have very low data-point-to-pixel ratio   However, I think they can be somehow useful when portraying proportions. I agree to use a table in most cases but when you are writing a business report and you've just included hundreds of tables why not having a pie chart?  I'm curious about what the community thinks about this topic. Further references are welcome.  I include a couple of links:         In order to conclude this question I decided to build an example of pie-chart vs waffle-chart. Why isn't a virus "alive"? The recent  about a new supermassive virus being discovered got me thinking about how we define viruses as non-living organisms whilst they are bigger than bacteria, and much more complex than we first gave them credit for.   What biological differences between viruses and cellular organisms have made viruses be deemed non-living? Why does Ubuntu 12.10 not detect my Win7 partition? I'm trying to install Ubuntu 12.10 alongside Windows 7 on my ASUS laptop and I'm new to all of this.   I'm using  the Ubuntu 12.10 64-bit ISO burned onto a CD.  The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options:   Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else.   If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of 750516Mb (750Gb), but that's not true because I have Windows 7.  I've already read through several questions and people have mentioned that you could only have 4 primary partitions. So I got hold of partition magic and removed my D: and E:, leaving me with primary C: partition and System reserved partition and a lot of unallocated space.  I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously.  How do fix this problem and install Ubuntu alongside Windows 7?

Is an increasing union of subspaces a subspace? Using Process.Start() to start a process as a different user from within a Windows Service I'd like to periodically run an arbitrary .NET exe under a specified user account from a Windows Service.   So far I've got my windows service running with logic to decide what the target process is, and when to run it. The target process is started in the following manner:   The Windows Service is started using "administrator" credentials. When the time comes, an intermediate .NET process is executed with arguments detailing which process should be started (filename, username, domain, password). This process creates a new System.Diagnostics.Process, associates a ProcessStartInfo object filled with the arguments passed to it, and then calls Start() on the process object.   The first time this happens, the target process executes fine and then closes normally. Every subsequent time however, as soon as the target process is started it throws the error "Application failed to initalize properly (0xc0000142)". Restarting the Windows Service will allow the process to run successfully once again (for the first execution).  Naturally, the goal is to have target process execute successfully every time.  Regarding step 2 above: To run a process as a different user .NET calls the win32 function CreateProcessWithLogonW. This function requires a window handle to log the specified user in. Since the Windows Service isn't running in Interactive Mode it has no window handle. This intermediate process solves the issue, as it has a window handle which can be passed to the target process.  Please, no suggestions of using psexec or the windows task planner. I've accepted my lot in life, and that includes solving the problem in the manner stated above. Windows 10 - disable reopening programs after restart/startup Occasionally, a forced restart is happening on my Windows 10 computer. When the OS is restarted every program that I've had prior to the restart is reopened at startup. The programs are reopened like I would just double-click them.  I usually hold 5-6 windows of Visual Studio and few more programs all together. When the above happens, I have to wait several minutes until I can start working, as everything takes ages to load.  Is there a setting to disable these programs from automatically opening at startup? Combinatorial proof for Stirling number of 1st kind's generating function So I see this identity a lot but I can't find a detailed combinatorial proof for it.  $$n(n+1)...(n+k-1)=\sum_{j=0}^k \begin{bmatrix}k \\j \end{bmatrix}n^j$$ Can someone please help?

How to Pass an Object Method as a Parameter in Delphi, and then Call It? I fear this is probably a bit of a dummy question, but it has me pretty stumped.  I'm looking for the simplest way possible to pass a method of an object into a procedure, so that the procedure can call the object's method (e.g. after a timeout, or maybe in a different thread).  So basically I want to:   Capture a reference to an object's method. Pass that reference to a procedure. Using that reference, call the object's method from the procedure.   I figure I could achieve the same effect using interfaces, but I thought there was another way, since this "procedure of object" type declaration exists.  The following doesn't work, but might it help explain where I'm confused...?  interface    TCallbackMethod = procedure of object;    TCallbackObject = class     procedure CallbackMethodImpl;     procedure SetupCallback;   end;  implementation  procedure CallbackTheCallback(const callbackMethod: TCallbackMethod); begin   callbackMethod(); end;  procedure TCallbackObject.CallbackMethodImpl; begin   // Do whatever. end;  procedure TCallbackObject.SetupCallback; begin   // following line doesn't compile - it fails with "E2036 Variable required"   CallbackTheCallback(@self.CallbackMethodImpl); end;   (Once the question is answered I'll remove the above code unless it aids the explanation somehow.) How to remove some pages from the navigation bullets in Beamer? I'm making a beamer presentation using the miniframes outer theme, with navigation bullets, and the subsection=false option, meaning the bullets are all on a single row. The problem I have is that, if one section has too many pages, the bullets overflow to the next section:  Section 1 Section 2 oooooooooooooooooooo   I tend to have many frames, some of them just asking a question, leading to the next detailed frame. I don't really need those frames to be represented by navigation bullets, and removing them would fix the problem. Any idea how to do that?  I could cheat by using overlays to have the question and the answer on the same frame, but that would be a mess...  Code example to answer percusse's question: this should give you one circle per frame, not one per subsection. If you add many frames in one subsection, the circles will overflow over the next section.  \documentclass[compress]{beamer} \useoutertheme[subsection=false]{miniframes} \begin{document} \section{S1} \subsection{SS1} \frame{1} \frame{2} \frame{3} \subsection{SS2} \frame{1} \frame{2} \frame{3} ... \end{document} What is the difference between user and service account?

How can I change my VPN connection settings in Windows 7 from the command line?  I know how to do it using the GUI but I really need to do it from the console.
