  • Who was your mentor? Where can I find mine?

    - by aredkid
    In many of articles I've read, finding a mentor is often suggested. One to who would guide, teach and more. (I wouldn't know the details, I don't have one, yet.) So, who was your mentor, if any? I have only had indirect mentors: professor at university, manager at work whom I've watched and learnt from the most. And otherwise, Twitter has been a great place to follow the professionals and discover more about the technologies that interest me. But I still wonder how I could find one because I can sense that I might be lacking in my experience. Ideas?

  • Installing updates from hard drive [closed]

    - by Ajay
    I am using Oneiric Beta 2. Installed it yesterday. Then downloaded 350+ MB of updates and installed it. Then when I tried to auto-mount my drives using Storage manager, I screwed up and the system will boot right up to the Ubuntu Splash screen, then turn off. Anyways planning to reinstall Ubuntu again. But I do not want to have to download the updates again. I have a copy of all the downloaded update files with me. Can anyone tell me how I can install the updates from the hard drive without downloading them again ?? Thanks in advance.....

  • Does Unity support disabling the global application menu?

    - by Michael E
    I'm fairly excited for Unity, as it looks like a promising new direction for Ubuntu. However, I do have a concern - will it be possible to use Unity without the global menu? I have my window manager set to focus-follows-mouse/sloppy focus, and find the productivity gains to be immense. Sloppy focus is incompatible, however, with global menus, as it is possible for the focus to change while you move from window to menu. Will Unity support an option to use window menus while still using Unity?

  • Dynamic MMap ran out of room when trying to sudo apt-get anything

    - by user1610406
    I was having an error in Update Manager that asks me to do a partial upgrade and it fails. Now I can't sudo apt-get install anything. I tried to fix it, and now I can't sudo apt-get anything. Every time, I get this output: Reading package lists... Error! E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf) E: Error occurred while processing libuptimed0 (NewVersion1) E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_lucid_universe_binary-i386_Packages W: Unable to munmap E: The package lists or status file could not be parsed or opened. I have no idea why this is happening or how to fix it, and I fear that if I try something that probably doesn't work that it will make my problem worse. (Just for reference I am currently running 10.04 (Lucid) on my machine.)

  • How can I get start openbox at login using the GNOME/Openbox session?

    - by skyblue
    I want to be able to run openbox as my window manager in GNOME. If I install openbox, I get the additional choices at the GDM login window of a 'GNOME/Openbox' and an 'openbox session'. If I log in with the 'openbox session', it starts openbox successfully. However, if I log in using the 'GNOME/Openbox' session so that I can run GNOME but just replace metacity with openbox, I find that openbox does not start, and that metacity is managing my application windows. It looks something is not working in the GNOME/Openbox session in 10.04 (and possibly other versions of Ubuntu). I know that I can manually replace metacity with openbox by typing 'openbox --replace', but I want to know the correct way of starting openbox in a GNOME environment automatically at logon.

  • Install Ubuntu or Kubuntu?

    - by squallbayu
    I want to upgrade my Ubuntu Lucid to Kubuntu Maverick (with a fresh install of course). I want to try KDE, but I have heard there are slight issues with the native QT applications compared to the GTK application equivalents - such as nvidia-settings, Gimp, Ubuntu Software Centre, and especially th eSynaptic package manager (which in detail showed the administration package / KPackageKit is not powerful yet than synaptic) I believe we can have run GTK+ applications in KDE, but GTK+ applications do not blend with the KDE desktop. Also Java does not provide a GUI for KDE/QT. Should I install Kubuntu (KDE / QT) or stay with ubuntu (GNOME / GTK +)?

  • Switching to Kubuntu results in low graphics mode

    - by HackToHell
    I looked at some screen shots of Kubuntu and I liked it so I went to Synaptic and installed the kubuntu-desktop package and set my desktop window manager to kde and rebooted. After reboot, I saw Kubuntu splash screen then this message; running in Low Graphical Mode. Then I was not able to dismiss the message because my mouse did not work Seemingly How to Geek had the same problem http://www.howtogeek.com/howto/ubuntu/install-kde-kubuntu-on-ubuntu/ . You will probably see that your xorg.conf file was backed up to xorg.conf.1 during the ?KDE / Kubuntu installation. Just copy the xorg.conf.1 back to xorg.conf, reboot, and everything should be fine. I also tried to do that by booting into recovery mode and then droping onto the shell. But it would not let me rename, came up with some error.

  • Multiple Vertex Buffers per Mesh

    - by Daniel
    I've run into the situation where the size of my mesh with all its vertices and indices, is larger than the (optimal) vertex buffer object upper limit (~8MB). I was wondering if I can sub-divide the mesh across multiple vertex buffers, and somehow retain validity of the indices. Ie a triangle with a indice at the first vertex, and an indice at the last (ie in seperate VBOs). All the while maintaining this within Vertex Array Objects. My thoughts are, save myself the hassle, and for meshes (messes :P) such as this, just use the necessary size ( 8MB); which is what I do at the moment. But ideally my buffer manager (wip) at the moment is using optimal sizes; I may just have to make a special case then... Any ideas? If necessary, a simple C++ code example is appreciated. Note: I have also cross-posted this on stackoverflow, as I was not sure as to which it would be more suitable (its partly a design question).

  • Mixing Forms and Token Authentication in a single ASP.NET Application (the Details)

    - by Your DisplayName here!
    The scenario described in my last post works because of the design around HTTP modules in ASP.NET. Authentication related modules (like Forms authentication and WIF WS-Fed/Sessions) typically subscribe to three events in the pipeline – AuthenticateRequest/PostAuthenticateRequest for pre-processing and EndRequest for post-processing (like making redirects to a login page). In the pre-processing stage it is the modules’ job to determine the identity of the client based on incoming HTTP details (like a header, cookie, form post) and set HttpContext.User and Thread.CurrentPrincipal. The actual page (in the ExecuteHandler event) “sees” the identity that the last module has set. So in our case there are three modules in effect: FormsAuthenticationModule (AuthenticateRequest, EndRequest) WSFederationAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest, EndRequest) SessionAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest) So let’s have a look at the different scenario we have when mixing Forms auth and WS-Federation. Anoymous request to unprotected resource This is the easiest case. Since there is no WIF session cookie or a FormsAuth cookie, these modules do nothing. The WSFed module creates an anonymous ClaimsPrincipal and calls the registered ClaimsAuthenticationManager (if any) to transform it. The result (by default an anonymous ClaimsPrincipal) gets set. Anonymous request to FormsAuth protected resource This is the scenario where an anonymous user tries to access a FormsAuth protected resource for the first time. The principal is anonymous and before the page gets rendered, the Authorize attribute kicks in. The attribute determines that the user needs authentication and therefor sets a 401 status code and ends the request. Now execution jumps to the EndRequest event, where the FormsAuth module takes over. The module then converts the 401 to a redirect (302) to the forms login page. If authentication is successful, the login page sets the FormsAuth cookie.   FormsAuth authenticated request to a FormsAuth protected resource Now a FormsAuth cookie is present, which gets validated by the FormsAuth module. This cookie gets turned into a GenericPrincipal/FormsIdentity combination. The WS-Fed module turns the principal into a ClaimsPrincipal and calls the registered ClaimsAuthenticationManager. The outcome of that gets set on the context. Anonymous request to STS protected resource This time the anonymous user tries to access an STS protected resource (a controller decorated with the RequireTokenAuthentication attribute). The attribute determines that the user needs STS authentication by checking the authentication type on the current principal. If this is not Federation, the redirect to the STS will be made. After successful authentication at the STS, the STS posts the token back to the application (using WS-Federation syntax). Postback from STS authentication After the postback, the WS-Fed module finds the token response and validates the contained token. If successful, the token gets transformed by the ClaimsAuthenticationManager, and the outcome is a) stored in a session cookie, and b) set on the context. STS authenticated request to an STS protected resource This time the WIF Session authentication module kicks in because it can find the previously issued session cookie. The module re-hydrates the ClaimsPrincipal from the cookie and sets it.     FormsAuth and STS authenticated request to a protected resource This is kind of an odd case – e.g. the user first authenticated using Forms and after that using the STS. This time the FormsAuth module does its work, and then afterwards the session module stomps over the context with the session principal. In other words, the STS identity wins.   What about roles? A common way to set roles in ASP.NET is to use the role manager feature. There is a corresponding HTTP module for that (RoleManagerModule) that handles PostAuthenticateRequest. Does this collide with the above combinations? No it doesn’t! When the WS-Fed module turns existing principals into a ClaimsPrincipal (like it did with the FormsIdentity), it also checks for RolePrincipal (which is the principal type created by role manager), and turns the roles in role claims. Nice! But as you can see in the last scenario above, this might result in unnecessary work, so I would rather recommend consolidating all role work (and other claims transformations) into the ClaimsAuthenticationManager. In there you can check for the authentication type of the incoming principal and act accordingly. HTH

  • LibreOffice english spelling dictionary missing

    - by rossouwap
    I've got two machines, same OS (Ubuntu 11.10 x86_64), same LibreOffice ppa's (ppa:libreoffice/ppa). One has the "English spelling dictionaries, hyphenation rules, thesaurus..." extension in the extension manager, the other doesn't. Each upgraded using the ppa from 3.5.0 to 3.5.1. Can anyone provide some insight as to how to get this extension onto the second machine? I can remove LibreOffice from the second machine and install the packages from the LibreOffice site, but would prefer to keep the ppa - as I don't then need to remember to upgrade.

  • Connected to wifi, but quits loading pages after a random amount of time

    - by Collin
    I'm using Ubuntu 12.10, on a TOSHIBA Satellite L755 laptop, and using a Cradlepoint MBR-1000 wireless router. The wifi supposedly works fine on my sisters' and mom's laptops, and my dad uses a wired connection through the router. Nobody else has the problem. It shows that I'm connected and everything. The network manager GUI shows that everything is going just dandy... but it's not. I'll be able to load a page or two, then I have to disconnect, and reconnect to the router to get it to work again for a couple minutes. I noticed when I was downstairs, close to the router, this problem seemed to go away (at least, I was connected for a couple of hours without running into this problem). When I run ping -n 8.8.8.8 it shows this while the connection is still running fine 64 bytes from 8.8.8.8: icmp_req=1187 ttl=47 time=665 ms and whe

  • Loading content (meshes, textures, sounds) in the background

    - by Boreal
    In my game, I am aiming for a continuous world, that is, a world where you can go anywhere without breaking the immersion through load times and "virtual seams". My world is broken up into regions, which are nodes in a graph. A region is considered adjacent to another if it can be travelled to or seen from that region. In order to keep this continuous, I want to preload the assets needed in the adjacent regions (such as world meshes, textures, and music) before they are actually used. As for actually loading the content, I use a manager that keeps at most one copy of each asset in memory at a time, accessible by its filename. When I try to access an asset, it loads it (if necessary) and then returns it. I can then unload any asset that is currently loaded to save memory. Clearly, I want to do this in the background so there are no hiccups. I assume I have to use threads in some way, but I'm not sure how.

  • What is wrong with Unix/linux

    - by John Smith
    This is a genuine question motivated by Ideal Operating System When I moved from DOS to Linux in the late 90s it was an eye opener for me. Long file names, arbitrarily many extensions etc... Now I look at Linux and Unix and see all sorts of issues. Here are things I see which could be fixed. Too much depends on root, and rootly powers cannot be voluntarily delegated over several users. (I would love to give up my power to manager printers and delegate the job to another account) File permissions are very limited, and there is not much metadata to go with files. The "everything is a file" metaphor is not true, Plan 9 gets it right(er).

  • Creating a Template Like System in cPanel

    - by clifgray
    I am creating a medium sized website using cPanel and their File Manager system and the majority of my pages are going to be the same with a different title and content section and I wanted to see if there is a system for making one general template file and then having all the other pages inherit from that file so all I have to do is have a content and title section and the rest of the links, headers, and whatnot can be changed throughout the site by just changing one file. Is there anything like this? I have used Jinaj2 in python and a few other systems for other server scripting languages but I am not sure how to implement it with cPanel.

  • window borders, menu bar missing over VNC

    - by zacaj
    I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

  • Quantitfying a cost for a software project

    - by The Elite Gentleman
    Disclaimer: I didn't know exactly where to put this question. If you feel that this question is not suitable for Programmers @ StackExchange, feel free to migrate it. Background: Broadening my last question, there is a request for tender for a software system that's open and I have decided to take it on. I am a software developer & engineer by profession and, in this tender process, I have to put on the pricing for my bid. I have been provided a documentation consisting of functional and non-functional requirements only. I have to put a project manager's cap on and think of all aspects, e.g. cost for implementation for the project, resources needed, etc. My question is: Is there a project framework that I can follow that breaks the project cycle into steps and corresponding cost aspect or how would I go about best calculating/approximating the cost for the project?

  • How do I provide arguments to an application launcher in kde?

    - by bobdobbs
    So I can create launchers in a quicklaunch thing on the kde desktop. The launchers are easy to create, and work most of the time. What I haven't figured out, is how to pass arguments to the applications that I want to launch. I want to launch the firefox profile manager and I also want to add a launcher for an emacsclient frame. For emacsclient, I've tried these: emacsclient -c "emacsclient -c" 'emacsclient -c' None of them work. When I click the launcher, the tiny emacs logo appears attached to the mouse pointer, and stays there for at least a couple of minutes, but no new frame opens. So, how can I actually open an emacsclient frame, or any other application with an argument from quicklaunch?
