• Ubuntu runs really slow on netbook

  - by Tim

  so I installed Ubuntu through Wubi in my netbook (Compaq Mini, 1.6 GHZ Atom, 1 GB RAM, 250 HDD, Windows 7 Starter) and decided to keep the original OS and run both... The thing is that, after I installed Ubuntu (really hyped: a couple of friends told me this OS was amazing, much faster and eaiser to use than Windows) and selecting it from the boot menu, I find that it runs really slow, sometimes freezing for a sec... For what I know, there must me be a partition in C:/ and a lot of HDD space for the Installation Size to make things faster, but I am sure I got those things right... Any help?? Also, why doesn't Wubi ask you for the DVD or bootable USB drive?? I'm just new in all this guys...

• Laptop not syncing with Ubuntu One

  - by Lolwhites

  I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.

• Creating an install of Ubuntu to clone

  - by naaronne

  I work on a team with several other developers. We all have similar hardware and we all run at least the same base development software. We are wishing to upgrade from 10.04 to 10.10 doing a clean install. I am looking for a way to do a base install of Ubuntu, including all our common applications, then clone it to each of the developers drives and then let them further customize their own install. Some considerations would be giving the developer the ability to have their own person id and not the same as which the base install was done with. I know they do this on VMware installs and corporate installs of Windows that can then be customized, but I have not seen this done with Ubuntu yet. Thanks

• How do .so files avoid problems associated with passing header-only templates like MS dll files have?

  - by Doug T.

  Based on the discussion around this question. I'd like to know how .so files/the ELF format/the gcc toolchain avoid problems passing classes defined purely in header files (like the std library). According to Jan in that answer, the dynamic linker/loader only picks one version of such a class to load if its defined in two .so files. So if two .so files have two definitions, perhaps with different compiler options/etc, the dynamic linker can pick one to use. Is this correct? How does this work with inlining? For example, MSVC inlines templates aggressively. This makes the solution I describe above untenable for dlls. Does Gcc never inline header-only templates like the std library as MSVC does? If so wouldn't that make the functionality of ELF described above ineffective in these cases?

• Garbled display after Ubuntu upgrade to 2.6.32-2* kernel

  - by Matthias

  I was running Ubuntu 9 (Karmic Koala) with no problems. I recently upgraded to Ubuntu 10 (Lucid Lynx) and cannot use it normally. After I log in, the screen scrambles (a purple/green mess)--impossible to see anything, although I can get out by marking the spot on the screen to click for a restart, so Linux is working behind the scenes. If I start in recovery mode with basic graphics, I have no problems at all (other than limited functionality). If I start the old 2.6.31-22 kernel, I see a bunch of "unmountable" errors in the startup script, but I can use Linux normally with no apparent problems. I'm running an IBM ThinkPad A30 with ATI Mobility graphics. Just to reiterate, the screen looks normal until I log in, at which point it goes bonkers. What do I need to change in order to fix this?

• Does the Ubuntu One sync work?

  - by bisi

  I have been on this for several hours now, trying to get a simple second folder to sync with my (paid) account. I cannot tell you how many times I removed all devices, removed stored passwords, killed all processes of u1, logged out and back in online...and still, the tick in the file browser (Synchronize this folder) is loading and loading and loading. Also, I have logged out, rebooted countless times. And this is after me somehow managing to get the u1 preferences to finally "connect" again. I have also checked the status of your services, and none are close to what I am experiencing. And I have checked the suggested related questions above! So please, just confirm whether it is a problem on my side, or a problem on your side. EDIT: In the mean time, here is what has changed, on top of what is mentioned just above. • My files went from 0MB to 71.9MB, and is still rising. • My first folder of 400.2MB is being filled with the data as I write this. The second folder has the folder sub-structure in place. • Both folders now show in the File Browser that it will be synchronized. I believe that right now, it is all back to normal and working fine, and I guess that's what a good night's sleep can do ;). And we're now only back to the point where synchronizing is slow, but will pick up with the release of Natty (https://wiki.ubuntu.com/UbuntuOne/FAQ/WhyIsItTakingSoLongForMyFilesToSync). But to get to the questions: My about says I use 11.04, Natty Narwhal, but I am quite sure the last distribution I installed was 10.10. Folder A is 400.2MB, and Folder B is 29.5MB I am on a DSL line, behind a regular fritz.box setting. No proxy servers in use, and I did not install any particular firewall features. No physical firewall, just the router (on which I have a TV signal as well), and 2 switches to get to this floor. Status: inactive The ubuntuone-indicator runs the same window as when I click on my name on the top-right corner and select Ubuntu one, or in the Control Center choose Ubuntu one. It wasn't supposed to go further than this was it?

• How to specialize a c++ variadic template?

  - by Serge

  I'm trying to understand c++ variadic templates. I'm not much aware of the correct language to use to explain what I'd like to achieve, so it might be simpler if I provide a bit of code which illustrate what I'd like to achieve. #include <iostream> #include <string> using namespace std; template<int ...A> class TestTemplate1 { public: string getString() { return "Normal"; } }; template<int T, int ...A> string TestTemplate1<2, A...>::getString() { return "Specialized"; } template<typename ...A> class TestTemplate2 { }; int main() { TestTemplate1<1, 2, 3, 4> t1_1; TestTemplate1<1, 2> t1_2; TestTemplate1<> t1_3; TestTemplate1<2> t1_4; TestTemplate2<> t2_1; TestTemplate2<int, double> t2_2; cout << t1_1.getString() << endl; cout << t1_2.getString() << endl; cout << t1_3.getString() << endl; cout << t1_4.getString() << endl; } This throws several errors. error C2333: 'TestTemplate1<::getString' : error in function declaration; skipping function body error C2333: 'TestTemplate1<1,2,3,4::getString' : error in function declaration; skipping function body error C2333: 'TestTemplate1<1,2::getString' : error in function declaration; skipping function body error C2333: 'TestTemplate1<2::getString' : error in function declaration; skipping function body error C2977: 'TestTemplate1' : too many template arguments error C2995: 'std::string TestTemplate1::getString(void)' : function template has already been defined error C3860: template argument list following class template name must list parameters in the order used in template parameter list How can I have a specialized behavior for every TestTemplate1<2, ...> instances like t1_4?

• Ubuntu One not syncing fully

  - by wurlyfan

  I have uploaded several folders of data to Ubuntu One from my desktop computer, over the last few weeks, and I can see that all the contents are there when I look at my account on the web. When I look at my laptop (connected to the same account), one of the first folders I uploaded hasn't downloaded completely. New folders added from either device seem to sync correctly, but this one older folder remains almost empty, even though the control panel says file syncing is up-to-date. I have plenty of space available. Stopping and restarting the sync daemon and rebooting the laptop are both ineffective. What can I do to make this folder sync fully? I don't want to risk losing the data (which now exists only in Ubuntu One), and I don't have a lot of broadband data to play with. I've seen several bugs relating to this sort of issue but they're all quite old and apparently fixed, while this is happening on new 13.04 installations on both desktop and laptop.

• Can't login to Ubuntu One

  - by Gabriel

  I uninstalled Ubuntu One about two months ago and now I re-installed it. I can still login with my account through the site (Ubuntu One) but the client keeps telling me "The authentication failed". If I try to use the Recover password option it also fails with telling me that my email address is not recognized (while I can use it with zero issues through the site) If I attempt to create a new account from the client, it also fails to load the captcha every time. Something is clearly broken here but I can't figure out what it is. Any ideas?

• How to handle a Tile Map Scrolling [duplicate]

  - by DGomez

  This question already has an answer here: Implementing a camera / viewport to a 2D game 1 answer i'm making a video game, and i'm having, i think, a concept problem. The game will be a platformer which will use tile maps, so to start i will create a mask matrix indicating the tiles to be loaded, and etc..., so my problem is, how to handle the scrolling? should i create a giant mask matrix indicating in each position of the whole level what is supposed to be loaded, and according to the position of the player, change the section to be drawed?? Is this a correct approach to this situation??

• a flexible data structure for geometries

  - by AkiRoss

  What data structure would you use to represent meshes that are to be altered (e.g. adding or removing new faces, vertices and edges), and that have to be "studied" in different ways (e.g. finding all the triangles intersecting a certain ray, or finding all the triangles "visible" from a given point in the space)? I need to consider multiple aspects of the mesh: their geometry, their topology and spatial information. The meshes are rather big, say 500k triangles, so I am going to use the GPU when computations are heavy. I tried using arrays with vertices and arrays with indices, but I do not love adding and removing vertices from them. Also, using arrays totally ignore spatial and topological information, which I may need studying the mesh. So, I thought about using custom double-linked list data structures, but I believe doing so will require me to copy the data to array buffers before going on the GPU. I also thought about using BST, but not sure it fits. Any help is appreciated. If I have been too fuzzy and you require other information feel free to ask.

• How to run ubuntu-tweak's janitor automatically?

  - by Eliran Malka

  My aim is to have the janitor running at startup, with a pre-configured profile (e.g. clear redundant packages and browser cache). The website is lacking any documentation or usage instructions, and I could not find any information on this here as well. I tried, naturally, to start ubuntu-tweak from the command line, hoping additional API exists that will come through in this (allegedly) simple task. I only got as far as: ubuntu-tweak -f janitor which is a step in the right direction, but what's still missing is a command for the clear action. Is such a command available, or is there any better way of achieving the desired behavior?

• Ubuntu One isn't syncing in Windows 7

  - by tuxtu

  Ubuntu One was working just fine in friend's computer on Windows 7. Problem is that, suddenly it has stopped syncing. I want to share some observation regarding this problem. Hope this could be helpful to solve the problem. If I upload any file directly on web (using browser), the amount of file size (KB/GB) changed in both places, Web dashboard and Ubuntu One control panel on Windows 7, but I can't find the file on PC. "File sync in progress" hangs on the U1 control panel on windows for indefinite time. If I keep any file in the U1 synced folder, that's not available on the PC and the total amount of file size isn't changed anywhere. "File sync in progress" dialogue is always there, since the starting of the PC. User using the PC with administrative previlage. Hope this problem will be solved quickly.

• Implementing a list with unique_ptr<>? [migrated]

  - by Alexander Duchene

  As I understand it, a unique_ptr signifies exclusive ownership. A singly linked list seems to fit this, with each node owning the next, like (pseduocode alert) class node{ public: unique_ptr<node> next; int value; }; but I don't understand how to perform operations like traversing the list, where I'm used to doing here=here->next; How do you implement data structures using unique_ptr's? Are they the right tool for the job?

• Ubuntu One lost most of my files!

  - by Max

  I keep in my UbuntuOne the source code of my projects as a back up. In the past it worked and I never had problem. It happened that I had to change the hard disk of my laptop and I installed a fresh Ubuntu 12.10 in the new one. First time I connected with UbuntuOne it downloaded my files, but when I went to see my projects almost all my c++ source code files were missing!!!... I tried to check if I still have them on UbuntuOne by accessing from the web but nothing... my work is lost forever. I don't know who to ask for help? Is there a way to get back my precious files? Honestly I can't trust this service any more, I'm very disappointed. (edit: thanks God I found a back up in one of my external hard disks. I won't trust Ubuntu One any more, it's buggy and quite slow. )

• In what way I can implement packet filtering function in C++/C#?

  - by Network study

  Background: I am going to design a firewall-like application (with GUI) which will include several functions such as Packet sniffing and packet filtering. Both of the functions should be implemented to support different protocol levels including application, transport, network and link layer. I only know a little in C#.Net programming to perform the IP packet sniffing. It is also known that packet filtering requires the techniques in WFP or LSP and packet sniffing in application requires dll hooking. Questions: I am not sure which programming language(either C++ or C#) would be suitable for designing such an application described above. If I want to implement the packet filtering function, any libraries will be needed? edit01: Someone suggest that winDivert would be helpful, is it true?

• does glBindAttribLocation silently ignore names not found in a shader?

  - by rwols

  Does glBindAttribLocation silently ignore names that are not found? For example, in a shader: // Some vertex shader in vec3 position; in vec3 normal; // ... And in some set up code: // While setting up shader GLuint program = glCreateProgram(); glBindAttribLocation(program, 0, "position"); glBindAttribLocation(program, 1, "normal"); glBindAttribLocation(program, 2, "color"); // What about this one? glLinkProgram(program);

• game programming career, vc++ reference and future of it [closed]

  - by Pappu Bacha

  1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

• How to check if a variable is an integer? [closed]

  - by FyrePlanet

  I'm going through my C++ book and have currently made a working Guess The Number game. The game generates a random number based on current time, has the user input their guess, and then tells them whether it was too high, too low, or the correct number. The game functions fine if you enter a number, but returns 'Too High' if you enter something that is not a number (such as a letter or punctuation). Not only does it return 'too high', but it also continually returns it. I was wondering what I could do to check if the guess, as input by the user, is an integer and if it is not, to return 'Not a number. Guess again.' Here is the code. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { srand(time(0)); // seed the random number generator int theNumber = rand() % 100 + 1; // random number between 1 and 100 int tries = 0, guess; cout << "\tWelcome to Guess My Number!\n\n"; do { cout << "Enter a guess: "; cin >> guess; ++tries; if (guess > theNumber) cout << "Too high!\n\n"; if (guess < theNumber) cout << "Too low!\n\n"; } while (guess != theNumber); cout << "\nThat's it! You got it in " << tries << " guesses!\n"; cout << "\nPress Enter to exit.\n"; cin.ignore(cin.rdbuf()->in_avail() + 1); return 0; }

• Postgresql has broken apt-get on Ubuntu

• Ubuntu 10.04 (Lucid) OpenLDAP invalid credentials issue

  - by gmuller

  This won't be a question, but a solution to an infuriating problem on Ubuntu 10.04. If you tried to deploy an LDAP server using this distro following the tutorials below, you'll be on serious trouble. Tutorials: https://help.ubuntu.com/9.10/serverguide/C/openldap-server.html https://help.ubuntu.com/9.10/serverguide/C/samba-ldap.html The error first appear, on the line: "ldapsearch -xLLL -b cn=config -D cn=admin,cn=config -W olcDatabase=hdb olcAccess" It simply won't allow admin to access the "cn=config", thus you won't be able to deploy the LDAP server correctly. After almost a week searching for a solution, I've found this page: https://bugs.launchpad.net/ubuntu-docs/+bug/333733 On comment #5, the solution is presented. Quoting the author: when you get to the setting up ACL part you all of a sudden need to use a cn=admin,cn=config, that doesn't exist creating a config.ldif with dn: olcDatabase={0}config,cn=config changetype: modify add: olcRootDN olcRootDN: cn=admin,cn=config dn: olcDatabase={0}config,cn=config changetype: modify add: olcRootPW olcRootPW: secret dn: olcDatabase={0}config,cn=config changetype: modify delete: olcAccess and adding it with ldapadd -Y EXTERNAL -H ldapi:/// -f config.ldif It's unacceptable that a Linux distribution, popular like Ubuntu, have such ridiculous bug. Hope it helps everyone!

• Ubuntu 12.04 KVM running Ubuntu 12.04 with linux-image-virtual crash on boot
