  • InputLayout handling

    - by Kikaimaru
    Where are you supposed to store InputLayout? Suppose i have some basic structure like. class Mesh { List<MeshPart> MeshParts } class MeshPart { Effect Effect; VertexBufferBinding VertexBuffer; ... } Where should I store input layout? It's a connection between vertex buffer and specific pass, i can live with just 1 pass but I still have diffferent techniques so i need at least an array with some connection to effecttechniques, but I would appriciate something not crazy like dictionary. I could also create wrapper for Effect and EffectTechnique, but there must be some normal solution.

  • Fitting an established site into a CI framework

    - by David
    I manage a rather large, feature full nightmare of a site which has no end of feature creep settings/options/etc. Up to now its been coded in a procedural/functional way and would like to move to an OO,MVC setup. I'm quite new to it all but have done alot of research and feel that CodeIgniter is a code choice of framework to use to help quicken the transfer. Before looking at a framework, I started constructing a list of objects to create classes out of: photos users forum topics forums blogs blog posts comments The trouble I have now, is I do understand where these generic/universal objects fall into the CI MVC setup. What is the best way to organise this kind of stuff? These classes can generally be used on multiple models/views/controllers.

  • Is having your own website important?

    - by Josh K
    How necessary or important is it? I try to keep a running list of blogs or sites to follow, but a lot of the time I pull up someone's profile and notice there isn't anything there. Is it really important? I understand are different levels of programming (from C/C++ system programmers to Rails and even Haskell and J) and not everyone works in a language easily worked with for web based applications. Not everything is web-centric, however with the advent of many popular and sometimes free services I don't think it's unreasonable to expect a majority of programmers to have a personal site.

  • I try install dhcp3-server, but /etc/init.d/dhcp3-server file is missing. Whats going on?

    - by hydroparadise
    I've found several how-to's that essentially go through the same process in setting up DHCP. Here's a link that has the list of step needed install and setup DHCP. I follow all the steps and find that the sudo /etc/init.d/dhcp3-server restart portion returns command not found only to reveal the the file doesn't even exist. I've installed (sudo apt-get install dhcp3-server) and uninstalled (sudo apt-get remove dhcp3-server) two or three times. I'm pretty sure my config files are good because I've had to check them three times. But I don't think I'm to that point of being able to see them action it. I cant control the process. Why is the file missing? How is it supposed to get there? Help?

  • What parameters to use to compare GUI frameworks / toolkits?

    - by gooli
    I'm doing some research on the best GUI toolkit to use for future products at the company. We're talking about a fairly large organizations with quite a bit of code and a complete rewrite project in planning. Don't ask. Anyway, I'm trying to create a list relevant parameters to judge the toolkits. What would you use to drive the comparison? Here's what I've got so far: Maturity Ease of development Ease of prototyping Ease of maintenance Size of hiring pool Available knowledge at the company Training costs Community size Community level of expertise (how hard to find good answers to complex problems) Amount of expert-level books available Ability to interface to other technologies Deployment considerations Visual aesthetics Ability to access OS resources Multiple monitor support (something that might come in handy in our particular application)

  • Is it safe to configure "Shutdown" on "When laptop lid is closed" ?

    - by Takkat
    To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

  • What are the security implications of running untrusted code on my server?

    - by rahmu
    I would like to set up an app that allows users to send their code and execute it on my server. The thought of running untrusted code makes me cringe, so I am trying to set up an exhaustive list of security threats that should be addressed. I am assuming I should strip down certain features of the language executed, like file access or (maybe) networking. I also come across terms like sandboxing or chroot. I know what they mean, but how should I actually use them? In short: What security threats should I address before allowing users to run their code on my machine, and how do I do it?

  • Do search engines rank internal redirects negatively?

    - by siverd
    A client is in the late stages (code complete) of a website redesign and unfortunately hasn't implemented 301 redirects to point high traffic pages to the new URL's. As I understand it our only option at this point is to create redirects within the CMS. Our CMS allows us to do this: www.mysite.com/category/current-page.html will redirect to www.mysite.com/new-category-name/new-page.html The site now uses custom logic on our 404 page to check this list of redirects and if one exists forwards the user to the new-page.html I understand that using 301 redirects would be the correct way to maintain our page rank but I think that would require a code change which isn't possible. Question How will search engines respond to this? Will they wait until the redirect happens and allow us to keep our page rank (authority, trust, etc) or will they see the 404 page and down-rank us? Worst case...will they make our new-page.html start from a rank of "0"? Thanks for your help.

  • Figuring out what object is closer to a certain point?

    - by user1157885
    I'm trying to create fog of war, I have the visual effect created but I'm not sure how to deal with the hiding of other players if they're within the fog of war. So right now the thing I'm trying to do is if another player is hiding behind a wall then not to render that player. I was thinking of doing it by sending a ray in the direction of all the players, and then creating a list of all the obstacles that ray collides with and then trying to figure out if an obstacle was closer than the player in order to predict the distance. But then I realized I'm not really sure how to figure out if the obstacle is infact closer or not because I have to account for all the dimensions, so I'm kind of stuck. First of all is this approach the correct way to go about it and secondly how would I calculate if the obstacle was infact closer taking into account the X Y and Z. Thanks

  • How to return older Thunderbird version?

    - by Holger
    today at startup my Tb (not precisely sure what version it was) asked if it should check compatibility of the lightning calendar addon. That is to say it displayed in a list windows the only item: lightning and said it was not compatible. Choices were "check" or "don't" check compatibility. I clicked on check and after nothing happened for several minutes on "cancel". So, now my Tb is upgraded to 15.0 and Lightning isn't there anymore. It never asked me to upgrade anyway and I urgently need my calendar now. Any suggestions warmly welcome! Holger

  • Security Alert for CVE-2011-5035 Updated

    - by Eric P. Maurice
    Hi, this is Eric Maurice again.  Oracle has just updated the Security Alert for CVE-2011-5035 to announce the availability of additional fixes for products that were affected by this vulnerability through their use of the WebLogic Server and Oracle Container for J2EE components.  As explained in a previous blog entry, a number of programming language implementations and web servers were found vulnerable to hash table collision attacks.  This vulnerability is typically remotely exploitable without authentication, i.e., it may be exploited over a network without the need for a username and password.  If successfully exploited, malicious attackers can use this vulnerability to create denial of service conditions against the targeted system. A complete list of affected products and their versions, as well as instructions on how to obtain the fixes, are listed on the Security Alert Advisory.  Oracle highly recommends that customers apply these fixes as soon as possible.

  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • Choice of Operating System Version for Azure Roles

    - by kaleidoscope
    Customers can now choose when their applications receive new operating system updates and patches by selecting which version of the operating system their applications will run on in Windows Azure.  Right now there is only one available operating system version (released on December 17th, 2009), but new builds with the latest updates and patches will be released regularly.  This new feature allows developers to test their applications when new patches come out before upgrading their production deployments. To select an operating system version for your application, add the new osVersion attribute to your service configuration file.  The full list of available operating system versions is maintained in the Configuring Operating System Versions topic in the Windows Azure MSDN documentation.   Sarang, K

  • Geronimo 3 beta - Another Apache project now compatible with Java EE 6

    - by alexismp
    You probably recall the addition of TomEE and WebSphere CE at JavaOne 2011 to the list of certified Java EE 6 products. This time, Apache Geronimo 3 beta 1 was released with compatibility with the Java EE 6 full platform and is now listed on the Java EE Compatibility Page in both the Web Profile and Full Platform categories. Not surprisingly, a good number of the components used in this Geronimo release are similar to those used in the TomEE certification. We now have 11 compatible Java EE 6 configurations to chose from and expecting more soon.

  • Share between Ubuntu machines

    - by Anero
    I'm sure it might be a very easy way to do this, but I haven't found how... I have two machines with Ubuntu 10.10 on the same network (just workgroup, no domain involved). On one of them I have shared a folder through Nautilus Folder Sharing. When opening the Network place on the second machine, I cannot see the first one listed, just Windows Network and when going into this folder I can see the Workgroup though when trying to go into it I get an Unable to mount. Failed to retrieve share list from server error. Is it required to do something else when sharing the folder through Nautilus?

  • Truecrypted Windows 7 missing in Grub2 after upgrade

    - by user287545
    I have an encrypted dual boot Windows 7/Ubuntu System and upgraded my Ubuntu today. Everything went smooth but my Windows is not shown in the Grub2-List anymore. Starting up I have the Truecrypt Bootloader and after entering the Password I get to Grub (now Grub2). There my Windows 7 entry is missing now. Here is my report: http://paste.ubuntu.com/7569182/ Updating Grub did nothing to it. My guess is that within Ubuntu it does not recognize my Windows Installation on sda1 anymore. I can't mount it aswell. I can only mount it via Truecrypt itself. I think I might have to manually insert the menu item for Windows into that Grub config file. I guess that after entering the password in the truecrypt bootloader it would be possible to start Windows if the item was there - just a guess though. Edit: I basically followed these steps to set up my system: Dual Booting Windows 7 with Ubuntu 12.04LTS with Truecrypt

  • Relation between " lines of the longest working program " in a language and familiarity with it?

    - by Tim
    In some computer master program online application, it says: Please list the programming languages in which you have written programs. For each language, indicate the length in lines of the longest working program you have written in that language. You may approximate, but only count those parts of the program that you wrote yourself. I don't quite remember that, and I have never counted the lines of each program. Do programmers always know approximately how many lines in each of his programs, and keep record of them? What is the relation between " lines of the longest working program " in a language and familiarity with it? Typically, how many lines will indicate the programmer being excellent, good, fair, or unfamiliar with the language? Is knowing "lines of the longest working program" really helpful?

  • How to include content from remote server while keeping that content secure

    - by slayton
    I am hosting collection of videos, for which I retain the copyright, on a file server that I'd like to share with family and friends. When a user visits the my fileserver via a web browser they are asked to authenticate using HTTP auth and then they are presented with a basic list of the files. I'd like to build web application that provides a clean interface with simply library functionality. However, this app will be hosted on a different server. I'm trying to figure out a security model for my file server that doesn't require the user to login to both the file-server and the hosting-server. I want to make this as easy as possible for my non-tech savy family while still maintaining security for my files.

  • After installing Windows XP I can't boot into Ubuntu 12.04 LTS

    - by Osama
    I know that this issue may have been happened to many people and answered many times. For some reason, I had to install Windows XP beside Ubuntu 12.04 LTS. Once I did that, I'm no longer able to log on to my Ubuntu. The booting list screen doesn't show up. I tried some ways to fix that, one was to try Boot Repair (of course after opening Ubuntu live from a USB), however, the program didn't open after the installation had finished !! So how can I fix that? I hope you guys stick a little with my problem until it is solved
