• Microsoft croit fortement au futur du NUI et veut intégrer l'Interface Utilisateur Naturelle à d'autres produits que Kinect

  Microsoft croit fortement au futur du NUI Et veut intégrer l'Interface Utilisateur Naturelle à d'autres produits que Kinect Lors du forum économique mondial de Davos, Microsoft a présenté sa vision et son enthousiasme pour le NUI ? ou Interface Utilisateur Naturelle (technologie de contrôle et de déplacement des objets avec les gestes), un technologie dans laquelle il place énormément d'espoirs et qu'il souhaite étendre à d'autres produits que Kinect. Un optimisme qui s'appuie sur une récente enquête, menée par Microsoft auprès d'environ 6 000 personnes, qui a révélé qu'environ 50% des utilisateurs étaient déjà familiers des technologies NUI, pourtant émergentes.

• Graphical corruption during Linux startup and shutdown - should I be worried?

  - by Macha

  For the last month, when starting up or shutting down my laptop under Linux, I would get graphical corruption. Startup has an colour inverted, grainy rendition of what should be displayed while shutdown has a red background with all the text replaced by grey rectangles. At the very least this affects Fedora, Ubuntu and Xubuntu. Windows is not affected. Outside of startup/shutdown the system is fine. Should I be worrying about this?

• Are there any GUI or user interface design patterns? [closed]

  - by Niranjan Kala

  I was curious about GUI design patterns, so I searched and got some information, including a list of UI patterns for the web. This UI patterns website says that: UI Patterns is a growing collection of User Interface Design Principles and User Interface Usability Patterns present on web applications and sites today. Are there any other design patterns for constructing websites or other user interfaces? Are there any books that describe these patterns? I'm particularly interested in patterns for Windows desktop development and web development in the .NET platform.

• What is the easiest (preferably) graphical way to clone a hard drive to an image that I can open later?

  - by Roland Taylor

  I need to make a (preferably) mountable image of an 80GB Hdd, and store it on another hard drive. Is there some way that I can do this without losing data? Thanks for the answers I've received so far. The system in question cannot be used right now due to a problem with the power button :( [ugh!], but the information will really be useful =)! Thanks to all who answered so far, if anyone else wants to give me some tips I'll leave this open for a bit, as I still have not yet been able to clone the drive.

• A Linux DHCP server that will listen on an non-broadcast (tap) interface?

  - by TomOnTime

  Are there any Linux DHCP servers that will listen to what Cisco calls an "unnumbered" interface, or what others might call a "NBMA" (non-broadcast) interface. I have a Linux system that connects to a number of others using GRE tunnels. The machines on the other end send DHCP requests to this machine, I can see them with tcpdump. However, ISC DHCP 3.0.3 refuses to listen to the interface because it is non-broadcast. The interface I'd like DHCP to listen to is: tap2 Link encap:Ethernet HWaddr removed-for-privacy inet6 addr: removed-for-privacy/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:518 errors:0 dropped:0 overruns:0 frame:0 TX packets:510 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:196242 (191.6 KiB) TX bytes:52425 (51.1 KiB)

• How to connect to the internet via command line or graphical utility given I can't click at the top of the screen?

  - by Ben

  My Ubuntu 12.04 installation has an input problem resulting preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question. For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available. The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on? (I'll happily edit in the output of any relevant terminal commands.) Thank you.

• L'interface de Windows 8 se prénommerait Mosh, et un Windows App Store tournant autour de Jupiter serait en chantier

  L'interface de Windows 8 se prénommerait Mosh, et un Windows App Store tournant autour de Jupiter serait en chantier Mise à jour du 11.01.2011 par Katleen Beaucoup de personnes ont été déçues de ne pas voir la démonstration tant attendue de Windows 8 lors du CES de Las Vegas. Du coup, les rumeurs reprennent de plus belle ! Ainsi, le blogger Paul Thurrott se fait l'écho d'une information qui n'a toutefois pas été confirmée officiellement : apparemment, l'interface du futur OS s'appèlera Mosh. Elle ne sera pas grand public, mais spécifique aux appareils mobiles comme les tablettes et ceux fonctionnant avec un système Windows embarqué. De plus, il semblerait qu'un Windows App Store voie le jour, et il sera...

• What configuration entries are changed through the graphical options interface?

  - by Shamaoke

  I use a localized version of Firefox whose options/preferences menu and about:config entries differ from the default English base distribution. When I'm discussing Firefox on international forums, it's hard to tell people what options I alter and what values I use, since the localized names are different. Is there an exhaustive list of the about:config entries that can be changed from the graphical preferences/options dialog; something I can use as a reference for translating my localized names?

• Information about rendering, batches, the graphical card, performance etc. + XNA?

  - by Aidiakapi

  I know the title is a bit vague but it's hard to describe what I'm really looking for, but here goes. When it comes to CPU rendering, performance is mostly easy to estimate and straightforward, but when it comes to the GPU due to my lack of technical background information, I'm clueless. I'm using XNA so it'd be nice if theory could be related to that. So what I actually wanna know is, what happens when and where (CPU/GPU) when you do specific draw actions? What is a batch? What influence do effects, projections etc have? Is data persisted on the graphics card or is it transferred over every step? When there's talk about bandwidth, are you talking about a graphics card internal bandwidth, or the pipeline from CPU to GPU? Note: I'm not actually looking for information on how the drawing process happens, that's the GPU's business, I'm interested on all the overhead that precedes that. I'd like to understand what's going on when I do action X, to adapt my architectures and practices to that. Any articles (possibly with code examples), information, links, tutorials that give more insight in how to write better games are very much appreciated. Thanks :)

• Is there a way how to customize my keyboard layout in Xubuntu in a graphical way (by clicking)?

  - by Honza Javorek

  Possible duplicate, but I really couldn't find a solution. I would like to adjust my US keyboard layout, e.g. to add possibility to type some special characters on combination of right Alt + another character, etc. Moreover, my arrow up is dead, so until I buy another keyboard, I'd like to use my right shift as my arrow up, ASAP. However, there seems to be no way how to edit my keyboard layout easily in Xubuntu :( I found no editor and I really don't want to spend years in some configuration files and terminal (not that I can't, but I really really don't want). KLE - the only editor I could find, but no installation guide, no package, no PPA, no idea how to make it working (and uninstallable if not needed one day) Editor in Ubuntu - apparently not present in Xubuntu I found several tutorials how to change the layout, but they all seems to be complicated and not easy to follow. I don't want to spend a weekend in terminal or so, I am looking for an app to launch, make some clicking, finish my work by hitting Save button and - done! Please, is there such solution? For humans?

• How to debug a fatal system crash - [graphical loop DOTA2]?

  - by Huw

  Whilst playing DOTA2, I occasionally and apparently randomly seem to be experiencing a fatal crash where the display freezes fixed and the audio loops over approx the last .5 of a second. Now, I'm interested in resolving this - but my trouble is I don't know where to start. The error appears non-reproducible (I've tried returning to games and deploying the same combination of events in hopes of pinning to to a certain shader etc), and I don't know which part of 'the stack' it might be coming from. Variables that occur to me: I custom build this system, did I do something wrong - is my PSU not providing enough power to the graphics card? I am running Steam and DOTA under Linux, could this new software have a bug Might it be something to do with my ATI Catalyst graphics drivers Is some other background process interfering I'm usually mid game when this occurs, so i quickly kill the power and reboot (when i'm lucky i can get back in with only 1-2 mins lost!). So my question here relates to logs. Where should I start to look or how might I set up logs to help me pin down a fatal crash of this kind by recording moments up to / before a crash and is this likely to be something I should push Steam to do, or is there something at a system level? Then perhaps I can return with a more specific question and perhaps even a bug report :) Many thanks in advance.

• Is there any guarantee about the graphical output of different GPUs in DirectX?

  - by cloudraven

  Let's say that I run the same game in two different computers with different GPUs. If for example they are both certified for DirectX 10. Is there a guarantee that the output for a given program (game) is going to be the same regardless the manufacturer or model of the GPU? I am assuming the configurable settings are exactly the same in both cases. I heard that it is not the case for DirectX 9 and older, but that it is true for DirectX 10. If someone could provide a source confirming or denying it, it would be great. Also what is the guarantee offered. Will the output be exactly the same or just perceptually the same to the human eye?

• Is this a pattern? Proxy/delegation of interface to existing concrete implementation

  - by Ian Newson

  I occasionally write code like this when I want to replace small parts of an existing implementation: public interface IFoo { void Bar(); } public class Foo : IFoo { public void Bar() { } } public class ProxyFoo : IFoo { private IFoo _Implementation; public ProxyFoo(IFoo implementation) { this._Implementation = implementation; } #region IFoo Members public void Bar() { this._Implementation.Bar(); } #endregion } This is a much smaller example than the real life cases in which I've used this pattern, but if implementing an existing interface or abstract class would require lots of code, most of which is already written, but I need to change a small part of the behaviour, then I will use this pattern. Is this a pattern or an anti pattern? If so, does it have a name and are there any well known pros and cons to this approach? Is there a better way to achieve the same result? Rewriting the interfaces and/or the concrete implementation is not normally an option as it will be provided by a third party library.

• Why does the use of interface-based programming appear to be limited to behaviour?

  - by Carnotaurus

  I have been doing a little thinking about inheritance vs. realization vs. composition. I am not about to post the whole detail here. So I was wondering, when are not talking about supporting unit testing: Why does interface-based programming seem to focus upon the grouping of common behaviour, e.g., IPettable (for an animal), IEditable (for a user control), ISubmitable (for a form), etc. Why does the use of interface-based programming appear to be limited to behaviour when we could pragmatically group not so much on behaviour but on commonsense physical similarities which could have nothing to do with behaviour? It is not that there is some limiting feature within OOP; so how come?

• How can I bind an interface to a class decided by an xml or database configuration at the launch of the application?

  - by ipohfly

  I'm re-working on the design of an existing application which is build using WebForms. Currently the plan is to work it into a MVP pattern application while using Ninject as the IoC container. The reason for Ninject to be there is that the boss had wanted a certain flexibility within the system so that we can build in different flavor of business logic in the model and let the programmer to choose which to use based on the client request, either via XML configuration or database setting. I know that Ninject have no need for XML configuration, however I'm confused on how it can help to dynamically inject the dependency into the system? Imagine I have a interface IMember and I need to bind this interface to the class decided by a xml or database configuration at the launch of the application, how can I achieve that?

• Visual Studio : les menus en capitales créent la polémique autour de l'interface de l'EDI, êtes-vous pour ou contre ces majuscules ?

  Visual Studio : les menus en lettres capitales créent la polémique Autour de l'interface de l'EDI. Et vous ? Etes-vous pour ou contre ces majuscules ? La polémique enfle. Et ce qui ne devait être qu'un détail ? les menus de Visual Studio 11 en lettres capitales ? est en train de devenir un sujet de débat enragé. Rappelons les faits. Microsoft, pour augmenter la lisibilité et l'ergonomie de son EDI, a décidé d'apporter des changements de design à son interface. La plus voyante était des couleurs grises (qui elles aussi ont fait hurler une partie de la communauté). La deuxième à frapper l'oeil sont ces lettres capitales :

• Can OpenVPN be set up so the server doesn't have interface that is part of the VPN?

  - by BCS

  I'm looking to set up a VPN (OpenVPN is my first choice but I'm not stuck with it) in such a way that the server that hosts the VPN is not visible from within the VPN. That is; any packet that a client sends via the VPN interface will get delivered to another client's VPN interface or get dropped. In the other direction, the server shouldn't have a VPN interface at all and normal network operations shouldn't be able to send packets on the network. Can this be done? All the docs I have found have assumed that clients will connect via DHCP (this requiring that the server connect at least to that extent) but I can't think of any reason that a VPN couldn't use static IP's or that the DHCP server couldn't be implemented inside the VPN (see edit) server without setting up a VPN interface on the server. Edit: Based on the link on bridged mode from Phil Hollenback's answer it seems that OpenVPN does in fact have the "internal DHCP server" that I'm thinking of.

• Associate a texture to an object (from a data-model, not graphical point of view).

  - by Raveline

  I'm writing a roguelike where objects and floor can be made of different materials. For instance, let's say we can have a wooden chair, an iron chair, a golden chair, and so on. I've got an Object class (I know, the name is terrible), which is more or less using a composite pattern, and a Material class. Material have different important properties (noise, color...). For the time being, there are 5 different instances of materials, created at the initialization of the game. How would connect an instance of Object with one of the 5 instances of materials ? I see three simple solutions : Using a pointer. Simple and brutal. Using an integer material-id, then get the materials out of a table when engine manipulates the object for various purposes (display, attack analysis, etc.). Not very beautiful, I think, and not very flexible. Using an integer material-id, then get the materials out of a std::map. A bit more flexible, but still not perfect. Do you see other possibilities ? If not, what would you choose (and why) ? Thanks in advance !

• Mocking using boost::shared_ptr and AMOP

  - by Edison Gustavo Muenz

  Hi, I'm trying to write mocks using amop. I'm using Visual Studio 2008. I have this interface class: struct Interface { virtual void Activate() = 0; }; and this other class which receives pointers to this Interface, like this: struct UserOfInterface { void execute(Interface* iface) { iface->Activate(); } }; So I try to write some testing code like this: amop::TMockObject<Interface> mock; mock.Method(&Interface::Activate).Count(1); UserOfInterface user; user.execute((Interface*)mock); mock.Verifiy(); It works! So far so good, but what I really want is a boost::shared_ptr in the execute() method, so I write this: struct UserOfInterface { void execute(boost::shared_ptr<Interface> iface) { iface->Activate(); } }; How should the test code be now? I tried some things, like: amop::TMockObject<Interface> mock; mock.Method(&Interface::Activate).Count(1); UserOfInterface user; boost::shared_ptr<Interface> mockAsPtr((Interface*)mock); user.execute(mockAsPtr); mock.Verifiy(); It compiles, but obviously crashes, since at the end of the scope the variable 'mock' gets double destroyed (because of the stack variable 'mock' and the shared_ptr). I also tried to create the 'mock' variable on the heap: amop::TMockObject<Interface>* mock(new amop::TMockObject<Interface>); mock->Method(&Interface::Activate).Count(1); UserOfInterface user; boost::shared_ptr<Interface> mockAsPtr((Interface*)*mock); user.execute(mockAsPtr); mock->Verifiy(); But it doesn't work, somehow it enters an infinite loop, before I had a problem with boost not finding the destructor for the mocked object when the shared_ptr tried to delete the object. Has anyone used amop with boost::shared_ptr successfully?

• How do I register a marker interface so it is visible in Plones's ZMI?

  - by joeforker

  I would like to register a marker interface so I can add it to objects in the ZMI. My product's configure.zcml contains: <interface interface=".interfaces.IMarkerInterface" /> and, after reinstalling, the interface shows up in the list of available interfaces. But if I try to add it to an object in the ZMI I get a ComponentLookupError. What's missing?

• In an iPad SplitView, how do I add a Date Picker control to the Root View?

  - by Dr Dork

  I'm diving into iPhone OS development on the iPad and one of the things I'm playing with is the SplitView template. The template provides a window with a UISplitView view, containing the Root View (on the left of the window) and the Detail View (on the right of the window). The Root View is a subclass of a TableView. Rather than having the entire Root View consist of a TableView, I'd like it to contain a DatePicker view along with the TableView under it. When I go into IB and try and drop a DatePicker into the Root View, it won't let me. It will only let me add a DatePicker view to the Detail View. Why wont IB let me drop a DatePicker view into the Root View? How can I add a DatePicker to the RootView in addition to the TableView? I'm still learning this new platform, so I apologize if these questions are absurd in any way. Thanks so much in advance for your help, I'm going to continue researching these questions right now.

• ExtJS GridPanel Scrollbar does not appear in IE7 but it does in Firefox, etc

  - by Snowright

  Setup I have an accordion layout containing a "properties" panel that nests two inner panels. The first inner panel holds a Ext.DataView, while the second panel is the Ext.grid.GridPanel in question. In the screenshot below, the white space containing the folder icon is the dataview, and below that is the gridpanel. Problem In Firefox, Chrome, and Opera, there is a scrollbar that appears when my gridpanel has an overflow of properties. It is only in Internet Explorer that it does not appear. I am, however, able to scroll using my mouse scroll button in all browsers, including IE. I've also tried removing our custom css file in case it was affecting it somehow, but there was no change in doing so. I'm not sure exactly what code I should show as I don't know where the exact problem is coming from but here is the code for the mainpanel and gridpanel. var mainPanel = new Ext.Panel({ id : 'main-property-panel', title : 'Properties', height : 350, autoWidth : true, tbar : [comboPropertyActions], items : [panel1] //panel1 holds the DataView }); var propertiesGrid = new Ext.grid.GridPanel({ stripeRows : true, height : mainPanel.getSize().height-iconDataView.getSize().height-mainPanel.getFrameHeight(), autoWidth : true, store : propertiesStore, cm : propertiesColumnModel }) //Add gridpanel to mainPanel mainPanel.add(propertiesGrid); mainPanel.doLayout(); Any help into the right direction would be greatly appreciated. Thank you.
