  • Writing to a structured buffer with a compute shader (D3D11)

    - by Vertexwahn
    I have some problems writing to a structured buffer. First I create a structured buffer that is filled with float values beginning from 0 to 99. Afterwards a copy the structured buffer to a CPU accessible buffer is made to print the content of the structured buffer to the console. The output is as expected (Numbers 0 to 99 appear on the console). Afterwards I use a compute shader that should change the contents of the structured buffer: RWStructuredBuffer<float> Result : register( u0 ); [numthreads(1, 1, 1)] void CS_main( uint3 GroupId : SV_GroupID ) { Result[GroupId.x] = GroupId.x * 10; } But the compute shader does not change the contents of the structured buffer. The source code can be found here (main.cpp): https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/main.cpp?at=default FillCS.hlsl: https://bitbucket.org/Vertexwahn/cmakedemos/src/4abb067afd5781b87a553c4c720956668adca22a/D3D11ComputeShader/src/FillCS.hlsl?at=default

  • Boot-up hangs unless I manually select the kernel in the bootloader

    - by The Photon
    In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

  • Wireless USB Adapter driver configuration

    - by Jones
    First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

  • Serious Forum Design Issue

    - by John
    I want to launch a school forum for a country. I'm in dilemma as to how to design this forum. Country will have many states, each state will have cities, each city will have many schools. Each school will have many classes( 1st - 12th). It looks like this: States - Cities - Schools - Classes I want to make each class as forum. Now the biggest problems are two fold: If I were to list even 1000 schools it will create huge number of forums and I don't think forum softwares(PHPBB, MyBB) are designed to support these many Secondly creating and maintaining huge forums is also very difficult. Ideally I'd like to duplicate existing forum hierarchy to new one. I've done lot of search and I've found that such type of forums are infeasible and such designs don't work. Leave alone the fact the nobody uses such a forum. Keeping in mind this, how should I go about designing this forum?

  • Force Your Mac to Sort Folders on Top of Files (Windows Style)

    - by Eric Z Goodnight
    Even die-hard Mac converts have their issues with Mac OS, and one of those problems is that OS X lists folders mixed in with all other files. Here’s how to fix that in under five minutes with a clever hack. You know you’ve had that issue. You’ve dug through your files looking for that one elusive folder, and because it’s jumbled in with all the other stuff, it’s more or less impossible to find. Have no fear, with no downloads or silly plug-in software, you can finally make Mac OS behave like Windows and Linux and list those folders in the proper order.  How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

    - by user43816
    I just experienced an unusual crash: I tried to click on a name entry in the contact list of Empathy. A crash happened. Usually I am asked then if I'd like to report the error to Launchpad, and Launchpad opens. This time the error message was: "Excuse me. Ubuntu 12.04 noticed an internal error. If you notice further problems try to restart your computer. Send an error report to Launchpad to help removing this problem?" This time Launchpad did not open automatically. A new window opened and I could read the relevant error report. Later I found the error report in the file /var/crash/_usr_lib_empathy_empathy-chat.1000.crash. Why went the course of action this time differently from other crashes? Why is the file /var/crash/_usr_lib_empathy_empathy-chat.1000.upload empty?

  • "mountall: Disconnected from Plymouth" error in VirtualBox

    - by jonpavelich
    I installed Ubuntu (from the 11.10 Alternate CD, selecting "command-line only" mode before installing) in Virtualbox (Mac OS X Lion host) like I've done numerous times before. Installation finished without any problems, and I rebooted into my new system. Got the splash screen, it loaded, and right where it should've given me a login prompt, I got (in orange) mountall: Disconnected from Plymouth. I can just hit control + alt (option) + F1 to get the login prompt on tty1, and the system acts normally. This happens on every boot. The disk has two partitions, a 250 MB /boot partition and a 99.75 GB encrypted partition. The encrypted partition has LVM on it. One volume group, 3 volumes (swap, / (root filesystem) , and /home. At first I thought the error was from one of the LVM volumes not mounting, but they are all accessible. It isn't a critical error, but it is annoying. Any ideas?

  • Does Ubuntu run well on an USB HDD?

    - by Klaus
    I have here a company notebook, and because the HDD is full encrypted, I cannot install an extra partition for another system that I would like to use in my free time. And I really need another system, because this crap Windows here with that much of anti-virus, anti-spyware, anti-whatever on it is so slow and annoying. What can I do? I could use an external USB HDD with another system. Because I would like to handle big files and so on, I don't want to use a USB stick. A USB 2.5 HDD + Ubuntu is what I think the best option. Here are my questions: Do I have to note something? Does Ubuntu run well on an external HDD? Do I have big performance problems (because of the USB HDD)? Should I buy a very fast HDD for much money or it is not that important? Any suggestions?

  • Motivation and use of move constructors in C++

    - by Giorgio
    I recently have been reading about move constructors in C++ (see e.g. here) and I am trying to understand how they work and when I should use them. As far as I understand, a move constructor is used to alleviate the performance problems caused by copying large objects. The wikipedia page says: "A chronic performance problem with C++03 is the costly and unnecessary deep copies that can happen implicitly when objects are passed by value." I normally address such situations by passing the objects by reference, or by using smart pointers (e.g. boost::shared_ptr) to pass around the object (the smart pointers get copied instead of the object). What are the situations in which the above two techniques are not sufficient and using a move constructor is more convenient?

  • How do you handle increasingly long compile times when working with templates?

    - by Ghita
    I use Visual Studio 2012 and he have cases where we added templates parameters to a class "just" in order to introduce a "seam point" so that in unit-test we can replace those parts with mock objects. How do you usually introduce seam points in C++: using interfaces and/or mixing based on some criteria with implicit interfaces by using templates parameters also ? One reason to ask this is also because when compiling sometimes a single C++ file (that includes templates files, that could also include other templates) results in an object file being generated that takes in the order of around 5-10 seconds on a developer machine. VS compiler is also not particularly fast on compiling templates as far as I understand, and because of the templates inclusion model (you practically include the definition of the template in every file that uses it indirectly and possibly re-instantiate that template every time you modify something that has nothing to do with that template) you could have problems with compile times (when doing incremental compiling). What are your ways of handling incremental(and not only) compile time when working with templates (besides a better/faster compiler :-)).

  • Why can't I get a working session with vnc4server

    - by ysap
    We have a couple of (identical) Ubuntu 11.10 machines, configured with gnome-classic, which we use as remote servers, and let our clients log into personal user accounts we create for them using vnc4server. We configured all the machines in the same way, following a short manual we compiled, describing how to download, install and prepare a few tools and our software. The connection usually works fine, but today I set up a fresh machine, and experienced problems. After installing vnc4server, I ran vncpasswd and copied the following startup file to ~/.vnc/xstartup: #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS gnome-session --session=gnome-classic & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & Then, I started vnc4server and used two viewers (the Ubuntu Remote Desktop Viewer and Windows RealVNC Client) in two other machines, but instead of getting my desktop, I see an empty window with a grey-ish background pattern like this: and the cursor is a bold X. What is wrong with the setup and why don't I get a remote session as expected?

  • Q&amp;A: Will my favourite ORM Foo work with SQL Azure?

    - by Eric Nelson
    short answer: Quite probably, as SQL Azure is very similar to SQL Server longer answer: Object Relational Mappers (ORMs) that work with SQL Server are likely but not guaranteed to work with SQL Azure. The differences between the RDBMS versions are small – but may cause problems, for example in tools used to create the mapping between objects and tables or in generated SQL from the ORM which expects “certain things” :-) More specifically: ADO.NET Entity Framework / LINQ to Entities can be used with SQL Azure, but the Visual Studio designer does not currently work. You will need to point the designer at a version of your database running of SQL Server to create the mapping, then change the connection details to run against SQL Azure. LINQ to SQL has similar issues to ADO.NET Entity Framework above NHibernate can be used against SQL Azure DevExpress XPO supports SQL Azure from version 9.3 DataObjects.Net supports SQL Azure Open Access from Telerik works “seamlessly”  - their words not mine :-) The list above is by no means comprehensive – please leave a comment with details of other ORMs that work (or do not work) with SQL Azure.

  • How to Make a 9 Layer Density Column [Video]

    - by Jason Fitzpatrick
    Density columns, layers of varying density liquid in a glass cylinder, are nothing new in the world of science demonstrations, but this nine layer one with seven floating objects is something to see. Courtesy of Steve Spangler Science, the experiment goes above and beyond the traditional five layer column by adding another four layers and sinking objects of varying density into the column. The end result is a colorful demonstration of the varying densities of liquids and solids.

  • How do you unit test your javascript.

    - by Erin
    I spend a lot of time working in javascript of late. I have not found a way that seems to work well for testing javascript. This in the past hasn't been a problem for me since most of the websites I worked on had very little javascript in them. I now have a new website that makes extensive use of jQuery I would like to build unit tests for most of the system. My problems are this. Most of the functions make changes to the DOM in some way. Most of the functions request data from the web server as well and require a session on the service to get results back. I would like to run the test from either a command line or a test running harness rather then in a browser. Any help or articles I should be reading would be helpful.

  • Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

    - by Jake
    I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

  • Dimming the backlight is irreversible on a Samsung Q210 notebook, what do I do?

    - by user27304
    I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs: Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2 4 Gigs RAM Nvidia 9200m GS (although system information in Ubuntu doesn't know) 194 GB HD OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works). Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.

  • 11.10 runs really choppy and slow, but not if I choose "Gnome Classic"

    - by Ingram
    I'd like to use Unity with Ubuntu 11.10, but everything from Unity runs really choppy and slow. I have an ATI graphics card and I have installed the drivers through "Additional Drivers". The drivers work, as I can play 3d games flawlessly. When I drag the mouse box around or drag windows around, it is really choppy. I previously had Ubuntu 10.10 and everything worked fine. I installed gnome 3 on 11.10 and it does the same thing Unity does, very choppy and slow graphics. However, if I choose Gnome Classic, everything is fine. I can drag the mouse box all around with no problems. I can drag windows around and it looks and feels great. Is this a bug with Unity? Are others experiencing this? Or is there something I can do to fix this?

  • How to to let Google know about dynamic content?

    - by Yaniv
    Im looking for the best practice to let Google know about a vast number of dynamically created content. Let's say (I mean - dream) that I'm Facebook, and I want to let Google to index all the users' posts. Sitemap.xml may be the answer for this but they are limited to 50,000 URLs in each site map. I know that I can create 500 sitemaps and create a sitemap for sitemaps, but they are also limited, 25,000,000 URLS sounds quite enough at the moment, but could cause problems in the future. I.E - stackoverflow already has 3 Million posts, probably sitemap is not the solution for them. Creating a page with paging, and links to all the dynamic data. i guess this is what stackoverflow did by creating this page here: http://stackoverflow.com/questions So I think that Option 2 is the answer, but it seems to me that sitemaps might have some added value. So what should i do?

  • What is the name for landing pages that are one long page?

    - by blunders
    Really don't see them much anymore, but here's an example of what I mean: From comments: These are "high pressure" sales pages, design to overload the user with information, sell them on the belief that what they're buying is what they need, normally have a lot of testimonials, highlighted text, etc. The pages I'm talking about are not user friendly, they're aggressive sales pitches designed to target users wanting to belief the webpage they just landed on will solve there problems for an "affordable" price. Here's an example: www_landingpagecashmachine_com (remove the underscores, since I'm attempting to avoid linking to a site like that...) Bonus points: if you're able to tell me the name of the guy/company that popularized these types of pages; recall hearing about his company years ago, after he died in a crash while racing on a track with his Ferrari club on the west coast of the US. (Update: Appears Corey Rudl was the guy's name, and his company was called "The Internet Marketing Center." Even with that info, I've still been unable to find the name for these type of pages.)
