  • GRUB2 panic: "No such partition"

    - by Android Eve
    I managed to install 10.04 on a system that already has 8.04 (separate partitions, of course). It also installed GRUB2 onto the MBR. After discovering that there is no menu.lst anymore, I edited /etc/grub.d/40_custom to point to where my other OS partitions are: menuentry "Ubuntu 8.04" { set root=(hd0,0) linux /boot/vmlinuz-2.6.24-28-generic initrd /boot/initrd.img-2.6.24-28-generic } menuentry "Windows 7 Ultimate 64-bit" { set root=(hd0,2) chainloader (hd0,2)+1 } GRUB2 displays the menu with those entries but when I select any of them, it refuses to load them, saying "No such partition". I know the partitions are there, as 10.04's "Disk Utility" sees them without any problem. How do I get GRUB2 to recognize them?

  • Grub errors dual boot Windows 8 / Ubuntu 12.10

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the grub menu, these tow errors show: "can't find command 'drivemap' " and "invalid EFI file path" and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

  • Recommend hosting with fast MySQL database please.

    - by Keith Groben
    I am frustrated to no end with my current hosting provider, mediaTemple. Yes, they are flashy, and have some decent degree of flexibility with their GS plan, which I have. But anytime I install a site that needs a database, it is slow. like really slow. Taking anywhere from 10 - 15 seconds just to load a page. I would host in house, but there are a lot of complications that come with a LAMP server that I don't want to deal with. Honestly, I'd rather spend the time developing. What can you recommend?

  • Macbook Pro (2011) Install of 12.10

    - by William Fleming
    I have installed Ubuntu on another partition on my macbook only to find when i boot using refit im greeted with a screen that reads Missing Operating System I have chosen to install grub on the root partition so i assume after the EFI boot-loader has done its stuff it will then load grub in the " / " partition. Any thoughts on this i couldn't find anyone with this problem. I can only assume its a problem with the GRUB install on the partition. But i have tried to reinstall it and it did not work....? Any thoughts would greatly appreciated. Bill

  • Ideal laptop specs for a Computer Science Masters student? [closed]

    - by Ayush
    I have a HP pavillion core 2 duo 2 GHz and 4 GB RAM, and it is painful to use this machine for any kind of coding. Eclipse (especially Juno) literally takes 5 minutes to load. And even after that, everything is lagy. Apart from school stuff, I also use my computer as a television. I watch Hulu, Netflix, YouTube etc in 720p, and this laptop gets hot as hell and the fans are loud enough to wake somebody up from deep sleep. I DON'T use my laptop for Gaming or Video/Photo Editing. I'm looking to buy a new laptop (in which most widely used IDEs would work smoothly and playing hi-def videos wouldn't be too much for the machine to handle) any suggestions (on hardware specs) would be greatly appreciated. Thanks

  • Stop Google Analytics from appending hostname?

    - by Nick Q.
    I've come across an Analytics profile that is appending the rest of a URL to the end of a page's path. For example when looking at the page that exists at http://example.com/page I would expect to see /page but instead it shows me /page/http://example.com/. The profile has no filters applied to it, and until July was reporting as expected (/page), in July the site in question switched hosts (and absolutely nothing else, so I'm not sure that's the problem). The analytics code on the site is the standard Google Async code with a domain set. All other profiles for the site show /page as expected. Any ideas as to how I can get the profile to function as expected?

  • Slow transfer to external USB3 hard drive

    - by JMP
    Trying to backup data from hard drive before reloading windows following some issue with its load. Having trouble with the file transfer to a USB3/2 external hard drive NTFS. Getting transfer speed of about 116.7kB/sec. In other words its taking about 5 hours to transfer 1.4GB. I've got about 80GB to go. So the transfer is going to take 11days. Seems a little on the slow side. Am I missing something? Is there a way to make this faster. No issue with the external drive transferring this amount in windows. But don't have that option at the moment.

  • How to apply a filter to the screen of a running program?

    - by Shahbaz
    The idea is to take old games without modifying them, but have the graphics card apply a series of filters to their output before sending them to the monitor. A very crude example would be to take a game that has a resolution of 640x480 and do: Increase the resolution to 1280x960 Apply a blur (low pass filter) Apply a sharpen (1 + high pass filter) These steps may not necessarily be the best to improve the visuals of an old game, but there are a lot of techniques that are well-known in image processing for this purpose. The question is, do the (NVidia) graphics cards give the ability to load a program that modifies the screen before sending it to the monitor? If so, how are they called and what terminology should I use to search? I would be comfortable with doing the programming myself if this ability is part of a library. Also, would the solution be different between Windows and Linux? If so, either is fine, since most of the games are probably runnable by wine.

  • Programming for Digital frames

    - by spartan2417
    A project has recently come to my attention but i have no idea where to start or even if its possible. The idea revolves around programming a clock that is displayed inside a digital photo frame. The user would then be able to put different pictures corresponding to different times inside a usb pen for example, which would load as soon as you put the usb in. The project itself would be a really neat project - if it was just on a computer. I have no idea if what im talking about it even possible on a digital photo frame and if it is what language? Anyone who has any input at all would be great. My current idea is to maybe have a small device at the back, SSD, that runs the program through a screen, completely by passing standard digital photo frames, again though i dont know how to begin with this. And yes ive tried google (although it helps to know what to google).

  • How to reload Variety wallpaper changer?

    - by mayur
    I have installed Variety desktop wallpaper changer. Its a good app. But sometimes when I start Ubuntu and login to my account it fails to load. I try to manually start the app by clicking on variety icon, but doesnt work. I tried alt+F2 and enter 'killall gnome-panel' but nothing seems to happen. I checked in my startup applications window, variety is present there to start when Ubuntu starts. but then why it does not start always? Restarting my pc is the only solution then. Is there a way that I can reload Variety without logging off or restarting Ubuntu? Thanks in advance.

  • applyAngularVelocity causes error when called right after object instantiation

    - by Appeltaart
    I'm trying to make a physicsBody rotate as soon as it is instantiated. CCNode* ball = [CCBReader load:@"Ball"]; [ball.physicsBody applyForce:force]; [ball.physicsBody applyAngularImpulse:arc4random_uniform(360) - 180]; Applying force works fine, the last line however throws an error in cpBody.c line 123: cpAssertHard(body->w == body->w && cpfabs(body->w) != INFINITY, "Body's angular velocity is invalid."); When I don't apply force and merely rotate the problem persists. If I send applyAngularImpulse at some later point (in this case on a touch) it does work. Is this function not supposed to be called right after instantiation, or is this a bug?

  • Effective way of keeping past projects with their working development environment?

    - by Korey Hinton
    I find that whenever I want to go run a past project, it will take a long time before I can find it and before I have everything set-up again for it to be able to run. For example, I have python projects I created in Linux, and it depends on software packages that are easily installed in Linux, yet I no longer have the Linux VM I was using. And some of my other projects depend on other variables like web server configuration, PATH variables, sdk, IDE, OS version, device, etc. Does someone have an effective way of handling this issue? As of now I have only concerned myself with keeping the source code backed up yet it is difficult re-establish the working development environment and it is also difficult to keep the working development environment around as well.

  • Best way of accessing data on different pages

    - by Gaz83
    I'm looking for a way to load data into properties/variables etc and have this information accessible to all the pages of my app. I want the information to be loaded via a background thread to keep UI thread free. Some of the pages will have various properties of their controls binding to these global properties. Here is what I tried. Created a static class. All pages could access the data but can't bind. Changed the static class to a Singleton and used DependencyProperty's. All pages could access data and binding worked fine but cross-threading issues when accessing via background threads. I have read in various places on this subject but haven't really come up with the best method yet for my situation.

  • Ubuntu 12.04 and Realtek Wireless Card Incompatible

    - by Tim
    Quick background: I installed Linux Ubuntu 12.04 on a Dell Inspiron 3520 after uninstalling Windows 8. A friend suggested to do this as opposed to buying a laptop with Linux pre-installed. Everything except the wireless card works. When I load up the laptop, I see a wireless animation as if it's trying to locate the wireless connection (for a while, then it goes blank), but no connections appear under the wireless option (under "Edit Connections" then "Wireless"). What I've tried: - Doing ndiswrapper. Failed. - Installing a few kernels for realtek. Failed.

  • Quantal analyzes the HD in any boot

    - by Lucio
    I have installed Ubuntu 12.10 formating the HDD. Any time that I turn on the PC and boot Ubuntu, it always analyzes my HDD in search for bad blocks. This is what happens: When I turn on the PC and load Ubuntu, before I can login my user, appears the following image. If I press C, the process ends and I can work, if I wait until the process can finish by itself also I can work. Also I had this problem, related to the HDD. My Hard Disk Driver is a Western Digital. Is there any problem on the system? Can I stop this procedure? Information that can help: tune2fs -l output

  • Design for future changes or solve the problem at hand

    - by Naveen
    While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

  • VMMap - awesome memory analysis tool

    VMMap is a process virtual and physical memory analysis utility. It shows a breakdown of a process's committed virtual memory types as well as the amount of physical memory (working set) assigned by the operating system to those types. Besides graphical representations of memory usage, VMMap also shows summary information and a detailed process memory map. Powerful filtering and refresh capabilities allow you to identify the sources of process memory usage and the memory cost of application features. Besides flexible views for analyzing live processes, VMMap supports the export of data in multiple forms, including a native format that preserves all the information so that you can load back in. It also includes command-line options that enable scripting scenarios. VMMap is the ideal tool for developers wanting to understand and optimize their application's memory resource usage. span.fullpost {display:none;}

  • 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?

  • Browser support for internal corporate tools

    - by adam
    We are on the verge of a conversion. For years, our company supported only IE for its internal (intranet) home-built tools. Since a few of our users are still on XP, which means IE only goes up to 8... a heavily JS / jQuery site wont even load! We have been in the process of converting to use Chrome instead, to make use of its javascript performance. But, it has now been suggested that we support all common browsers... internally for these tools. Which means more development time to scale-back some of these new applications, more time to test in all browsers, and we are already under staffed. Are there any good informational sites/posts out there, that already make this argument?

  • How do I select DWM or fluxbox to start on login?

    - by axe
    I am trying to setup DWM in Ubuntu 10.10. The package is successfully built - and now I am trying to get it up and running. I created the dwm.desktop file with the proper text and the path to the dwm exec is correct. On login screen, I can see dwm as a alternate session : but if I select it, still gnome starts. I even tried another window manager (fluxbox) - same problem. I can see and select it in the login screen, but gnome starts up. Trying gconftool-2 -s /desktop/gnome/session/required_components/windowmanager dwm --type string also does nothing. Killing the windows manager just restarts it - even if I chvt first. Also, don't see the xinit daemon running. Any ideas ? This setup was trivial in Debian, and older versions of Ubuntu. What changed ? I am guessing gnome integration is to blame - but am clueless as of now.

  • What do you do when one thinks the code isn't complicated enough?

    - by Chris
    After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?
