  • Drawing of a huge model - How to regain performance?

    - by marc wellman
    I have a huge model I want to draw in my XNA application but because of its size I am experiencing a tremendous loss of performance. The model has about ~50 000 000 edges and has a size on disk of 205 MB in DirectX Format. Please don't ask whether this model has to be that big - yes it has! Is there a way to transfer the model directly to my GPU in order to let the GPU do the drawing like when transferring a VertexBuffer like this: graphicsDevice.Vertices[1].SetSource(_instanceBuffers[i], 0, _sizeofMatrix); because when I try to fill a vertexBuffer with all the vertices I am getting a OutOfMemoryException.

  • How to fix an annoying ReSharper &ndash; NuGet error

    - by terje
    Originally posted on: http://geekswithblogs.net/terje/archive/2013/10/30/how-to-fix-an-annoying-resharper-ndash-nuget-error.aspxUsing NuGet in Visual Studio together with ReSharper may sometimes lead you into an annoying error where ReSharper indicates your code has an error, but the solution builds just fine. This may happen if you have a set of NuGet packages, and you either just restore them, or delete them on disk and then restore again.  Your code ends up looking like this, note the red missing functions, which comes from the Moq library - which is downloaded from NuGet:   while the Build is still fine, it compiles without any errors: This stackoverflow question gives some different approaches to solve this, but my experience have been that the Resharper Suspend-Resume trick most often solves the issue: In Visual Studio:  Go to Tools/Options/Resharper Press Suspend: When this is done the error markers disappear, since ReSharper now is inactive. Then just press Resume again: This has been submitted to Jetbrains support, ticket here: http://resharper-support.jetbrains.com/requests/3882) , if you want to follow it.

  • Best partition scheme [WIN7 | Ubuntu | Media | Home]

    - by Rockiano
    I just got a new HD (750GB of which 700GB are usable) and I want to partition it taking in consideration: Media (200GB) Home (300GB) Win7(150GB) Ubuntu(50GB) (I have 6GB of ram, would i need to consider a swap partition) The Media and Home partitions usually are left untouched, but once a month (or in some cases more) I will be formatting Win7 and/or Ubuntu, changing their sizes and even creating a third partition for a second ubuntu/win7 instance (using the 200GB originally assigned for them) What would be a good/best partition scheme to avoid problems in the Media and Home partition (And the hard-drive in general), considering they are highly unlikely to change and that also the Win7 partition is the less unlikely to be changing in relation to the ubuntu partition? I hope I'm clear enough and if any more details are missing please let me know. Thank you in advance.

  • Finding files at more speed

    - by Chaitanya
    I have been using find command to find files on my 1 tb hard disk. it takes very long. then I used locate which proved to be faster with regular update using updatedb. But the limitation of locate is that I cannot find files with certain size or modified/created time. can you suggest me any ideas on how to find files at more speed or in that case how to pipe output of locate command in a way that all other information like size, time, etc. can be displayed or redirected to a file.

  • Why dosn't Ubunto like my HP Pavilion G7?

    - by user109379
    I installed Ubunto onto my HP Pavillion G7 1330dx without much problem, but it took 3 or more tries to get it to boot up after. Then , I started over and installed Mint, no problems installing or booting up. BUT, I decided I I liked Ubunto better so I wiped my hard drive and installed Ubunto ( this time the 32 bit) ,It runs great once i finally get it to boot, it takes 3 or more tries again. Whats the deal? I really like it but really don't know what I'm doing. I've been a Windows guy until a couple days ago.

  • Video crashes with 10.10

    - by John Mahon
    I have installed both the 64bit and 32 bit versions of 10.10 on my Compaq Presario PC. I first installed the 64 bit version of the OS.The video often crashed when switching user. It also went haywire occasionally when I visited some web-sites. I read that there may be some problems with the 64 bit OS. So I installed the 32 bit version on another disk. This version seemed even less well behaved. HP's model number for the computer is SR1838NX. The hardware is listed at http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00628274&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=1841793&prodTypeId=12454&printver=true#A0 I think the important info is that the chip set is "ATI Radeon Xpress 200" and the processor is "Athlon 64 (S) 3700+ 2.2 GHz" Has anyone else had video problems with similar machines? Is there a work around or an update? I have had previous versions of Ubuntu working on this machine and other flavors of Linux as well. Thanks in advance. John

  • USB-live does not save files between sessions

    - by Mads Skjern
    I created a USB-stick with Ubuntu, using the recommended tool "Startup Disk Creator" and the image for Ubuntu 13.10. The very simple interface looks like this: There can't be much to misunderstand in this GUI. I have chosen to create a USB stick with a live version of Ubuntu, which will save files and settings from session to session, on the USB drive, right? Well, it just doesn't save anything. I go in, create a file on Desktop, restart and it's gone. I did the whole procedure three times, i.e. first creating the USB, then testing if I could save. Have I misunderstood something?

  • Problem with lucid install from ISO.

    - by joon
    Hi, I am trying to install Lucid from an iso (bios doesnt let me boot from USB and dvd drive is busted). I followed the instructions on the bottom of this page: ´The CD image approach´ https://help.ubuntu.com/community/Installation/FromWindows The ubuntu ALTERNATE iso is in my c: root dir. I even tried a fix that used to work in older versions (found on a forum) but that did nothing. What happens: - boot until the boot.ini menu - select install ubuntu - select install ubuntu again, I´m assuming this is grub - do some country settings,.. - harddrive is scanned for ISO image - not found, not even with thorough search...

  • What is the default permission for /var/www?

    - by itsols
    After upgrading to 12.04, I had to reinstall the LAMP stack. Then I brought all my www project folders from a pen drive to the /var/www folder (using sudo nautilus, and dragging the files in there). Now I cannot make any changes to the files/directories within /var/www. Perhaps this changed with the backup copies I dragged in there. I'd like to know what the default permissions for the /var/www folder are. I don't want to just change the permissions and make my system abnormal and working. Rather I'd like to get it to the correct state that is meant to work.

  • Can you delete the Humanity icon theme safely?

    - by Alex
    I'm trying to reduce used space after running disk usage analyser, since I'm using a 40GB SSD. The icons use quite a bit of space! Could I delete those that I don't use, such as humanity? (I use Faenza-Dark) If it is possible, what would be the best way to this? as when I attempt to remove humanity in the Software Centre it says the software-centre itself must be removed. Similar problems arise with synaptic package manager. I was wary of just deleting the unused directories in usr/share/icons/. Thanks for the help!

  • How to retrieve data from a corruped volume

I had ubuntu installed in ext4 file system and I am also having the same filesystem in the same hard disk on different drive. When I try to access my previous filesystem, i get error Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I had some important files in the previous volume, I don't know how to retrieve them.

  • How to set-up a simple subversion workflow

    - by Milen Bilyanov
    I am trying to set-up a simple SVN workflow at home. I am new to subversion (and programming) so I have been reading the official PDF documentations but still not sure about how to set-up my repository. I am working mainly with python, bash and rsl (Renderman Shading Language) So I already have a /dev structure on my disk as this: http://imageshack.us/f/708/devstructure.png/ And I have a /site structure that links to my /dev folder: http://imageshack.us/f/651/sitestructure.png/ So obviously starting to use SVN will change this approach that I already have in place. The question is when I am setting-up my SVN repository for the work I do in my /dev folder: Will I set-up a separate repository for each different programming platform? and Where exactly I should be placing my repository? Thanks.

  • How can I get wireless working on an HP-Mini 110-3150?

    - by jfmessier
    I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off. How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ? Merci :-) Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

  • Configuration server problem after changing /tmp mountpoint: how to solve?

    - by Aron Rotteveel
    I created a new partition on my hard drive because my /tmp partition was too small. I changed the mountpoint in /etc/fstab and rebooted. Every time I reboot, I get the following error message at the login screen: There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256) When I log in, /tmp is mounted correctly and everything seems to work fine. When I reboot, the error shows again. When I change the /tmp mountpoint back to the old partition, the error message disappears. What could be causing this and how can I solve this issue?

  • Seizing the Moment with Mobility

    - by Divya Malik
    Empowering people to work where they want to work is becoming more critical now with the consumerisation of technology. Employees are bringing their own devices to the workplace and expecting to be productive wherever they are. Sales people welcome the ability to run their critical business applications where they can be most effective which is typically on the road and when they are still with the customer. Oracle has invested many years of research in understanding customer's Mobile requirements. “The keys to building the best user experience were building in a lot of flexibility in ways to support sales, and being useful,” said Arin Bhowmick, Director, CRM, for the Applications UX team. “We did that by talking to and analyzing the needs of a lot of people in different roles.” The team studied real-life sales teams. “We wanted to study salespeople in context with their work,” Bhowmick said. “We studied all user types in the CRM world because we wanted to build a user interface and user experience that would cater to sales representatives, marketing managers, sales managers, and more. Not only did we do studies in our labs, but also we did studies in the field and in mobile environments because salespeople are always on the go.” Here is a recent post from Hernan Capdevila, Vice President, Oracle Fusion Apps which was featured on the Oracle Applications Blog.  Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt. Blurring the Lines between Work and Personal Life My vision of where businesses will be five years from now is that our work lives and personal lives will be more interwoven together. In turn, enterprises will have to determine how to make employees’ work lives fit more into the fabric of their personal lives. And personal devices like smartphones are going to drive significant business value because they let us accomplish things very incrementally. I can be sitting on a train or in a taxi and be productive. At the end of any meeting, I can capture ideas and tasks or follow up with people in real time. Mobile devices enable this notion of seizing the moment – capitalizing on opportunities that might otherwise have slipped away because we're not connected. For the industry shapers out there, this is game changing. The lean and agile workforce is definitely the future. This notion of the board sitting down with the executive team to lay out strategic objectives for a three- to five-year plan, bringing in HR to determine how they're going to staff the strategic activities, kicking off the execution, and then revisiting the plan in three to five years to create another three- to five-year plan is yesterday's model. Businesses that continue to approach innovating in that way are in the dinosaur age. Today it's about incremental planning and incremental execution, which requires a lot of cohesion and synthesis within the workforce. There needs to be this interweaving notion within the workforce about how ideas cascade down, how people engage, how they stay connected, and how insights are shared. How to Survive and Thrive in Today’s Marketplace The notion of Facebook isn’t new. We lived it pre-Internet days with America Online and Prodigy – Facebook is just the renaissance of these services in a more viral and pervasive way. And given the trajectory of the consumerization of IT with people bringing their personal tooling to work, the enterprise has no option but to adapt. The sooner that businesses realize this from a top-down point of view the sooner that they will be able to really drive significant innovation and adapt to the marketplace. There are a small number of companies right now (I think it's closer to 20% rather than 80%, but the number is expanding) that are able to really innovate in this incremental marketplace. So from a competitive point of view, there's no choice but to be social and stay connected. By far the majority of users on Facebook and LinkedIn are mobile users – people on iPhones, smartphones, Android phones, and tablets. It's not the couch people, right? It's the on-the-go people – those people at the coffee shops. Usually when you're sitting at your desk on a big desktop computer, typically you have better things to do than to be on Facebook. This is a topic I'm extremely passionate about because I think mobile devices are game changing. Mobility delivers significant value to businesses – it also brings dramatic simplification from a functional point of view and transforms our work life experience.
