• Ubuntu 12.04 LTS Wireless Asus USB-N53 (rt3572sta) driver installation issue

  - by Jake Thompson

  My purchase of the Asus USB-N53 just came in today and I spent several hours Googling and researching drivers for this device. When I first plugged the device in it connected fine to my open system, WEP, DHCP configured access point. I opened Google Chrome and a few pages loaded, everything seemed fine. 30 seconds later... Boom! It disconnected and showed attempts to reconnect and asked for the WEP key and just showed a state of infinite connection time until it asked me for the password again. I'm using amd64 (64 bit Ubuntu desktop 12.04 LTS) The official driver can be found here although I had no luck with it. lsusb: Bus 003 Device 002: ID 0b05:179d ASUSTek Computer, Inc. uname -a Linux Jake 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ----------------------------------------------------------------------------------Solved: I must of done something wrong when I originally installed the latest drivers from the chipset manufacturers website. I tried reinstalling and did modprobe rt3572sta and waited maybe 10 minutes??? and I connected then I rebooted and everything seems to be working so far. What I did do before hand is unplug the device and typed into the terminal (once for every source I attempted to install): cd '<directory of the driver source>' make uninstall make clean Then I went into the 2.5.0.0 directory and installed that with make make install Then I typed modprobe rt3572sta This was all in superuser. For those who don't know: sudo su

• How did I get here? My route to Android, iPhone, Windows Phone 7, and interest in Mobile Devices

  - by Wallym

  I get asked all the time how/why I got interested in mobile and jumped on this fairly early.  I tend to give half answers because it wasn't just one thing that took me to mobile, but a whole host of separate ivents culminating in a specific event where I wasdoing market research in May/June 2008.  Let me throw out the events and the facts about me: I tend to like new, different, cool stuff.  I jumped on .NET early on.  I jumped on Ajax early on.  I don't jump on every new technology that comes down the road, I'm probably the only person on the planet that doesn't "get" MVC, though I acknowledge that a lot of people do and it solves a number of problems in the default settings of ASP.NET WebForms. I remember buying an early Windows CE device. It was interesting, but dang, this stylus thing sucks. After I lost my third stylus, i just gave up.  I got my first mobile phone in early 1999.  Reception was crappy, but I could see the value in being mobile. In 1999, I worked on a manufacturing systems project.  One piece of the projects was a set of handheld devices on the shop floor.  While the UI was a crappy DOS based, yes I said DOS as in Disk Operating System Version 6.22, I could see that the wireless world was a direction I wanted to be in. In 2000, Microsoft released the first public alpha of .NET.  Very cool stuff indeed.  One piece of the puzzle was a set of mobile controls for ASP.NET.  I build numerous test apps as well as mobile version using these mobile controls.  Now, the mobile UIs of the time were based on WML, which was crap. I could real all the analysis of mobile and read all about growth rates.  Now, you have to realize that growth rates can be impressive when dealing with small numbers, but I knew it was a comer. In our first book, I got talked out of mobile because of the line from the publisher "Wally, mobile doesn't sell." Blackberry was the dominant device of the mid 2000s.  Its users were referred to as "Crackberry addicts."  Unfortunately, the mobile development experience for native apps was crap and the web experience was fairly rough as well, but if they could get the ecosystem started, other phones and better blackberryies would come out.  I finally jumped into using a blackberry. Sometime around 2006, I heard "Wally, mobile doesn't sell" again.  Now, anyone that knows me knows that someone saying something like this to me means I'll keep trying it. The phones of the mid 2000s were moving to be more graphical, but there were too many that had this idea that they had to use a stylus.  Stylus suck.  They get lost too easily. I worked on a project in 2007 and 2008 for a startup trying to answer the question of "What is there to do where I am at?"  For some reason, they wanted to be tied to PCs.  As it became obvious that they were having problems, their investor asked us to do some market research and to figure out what the marketplace did want.  One of the important things that I figured out was the we lived in a mobile world and if you had a mobile app, it need to be on a mobile device, not tied to a desktop/laptop/netbook device.  If there was any single event, this was it - I was doing some market research and sat and talked to people in a bar/restaurant in Atlanta called "The Grove" on Lavista.  The consensus of the people that I talked to was that they wanted their data where ever they were at, laptop, pc, mobile, whereever. In 2007, Apple released the iPhone.  Wow, what an impressive device, even with all the problems of a 1st generation device.  I bought an iPod Touch 1st generation to understand touch better, one of the best decisions I ever made. I decided in late 2008, to make a move into cloud, for a number of reasons.  I was working on an example app.  In April, 2009, one of my friends at Microsoft said "don't mention my name with this, but you need an iPhone front end for this app."  How do you get on the iPhone.  Well, there are a number of ways including: ObjectiveC.  Its hard to teach an old dog new tricks, and this dog knows .NET, not ObjectiveC. HTML, web, javascript optimized interface.  yeah, this is possible. PhoneGap.  Now, this is interesting, take an html interface and get it to run on the iPhone, Android, Blackberry, and other platforms.  I thought that this way made the most sense for me until......... MonoTouch.  In May/June 2009, Novell announced a way for .NET/c# developers to write apps for the iPhone.  This is the way that made the most sense to me. Titanium by Appcelerator.  This is similar in concept to PhoneGap.  I haven't played with this much but do want to learn more about it. In July, 2009, I emailed one of my contacts at Wrox to see if they would be interested in a short MonoTouch ebook in their Wrox Blox format.  I fully expected another  response along the lines of "Wally, mobile doesn't sell."  The response I got was "Wally, iPhone is H O T, get started immediately, can you have this to me before Labor Day."  Not quite the response I expected.  Thankfully, we didn't make the Labor Day, first draft date. I kept pushing back because I had a feeling that things were not going to be quite as polished and feature rich as necessary.  After all, Novell doesn't have the resouces of Microsoft's developer division. The ebook shipped on November 30, 2009. On about December, 15, 2009, my editor emailed and said "Your ebook is selling really well, lets do a full book and it by March 1 so get started."  Thankfully, guys like Craig Dunn and Chris Hardy were interested along with Martin and Ror joinged us later on. I bought my wife an iPhone 3Gs in early 2010 to go along with all my iPod Touch devices. I tried to pretend in 2010 that I wasn't that interested in mobile and still had interest in the desktop technologies.  I love the technologies and continue to use them today, but that isn't where my interest is right now.  I'm just about all mobile all the time with my energies.  Our book shipped in the beginning of July, 2010 right in the middle of the Apple FUD.I've been looking at Mobile Web as a way around the AppStores and Apple FUD problems of 2010. With all the Apple self FUD, we became interested in Android.I went up to Dino Esposito at DevConnections in Las Vegas at introduced myself. I've always tried to keep up with what Dino has been doing. I was shocked, he wanted to meet me.  We must have talked for 1.5 hours. It was way more time than I deserved. If you get a chance, go and introduce yourself to Dino. He's a great guy. Microsoft released Windows Phone 7 in the Fall of 2010.  I'm not doing development on that platform at this time.  I think they have a very interesting user interface.  The devices are being positively reviewed.  For my purposes, the devices are limited at this point in time.  We'll see what 2011 brings as far as updates to the operating system.  I need multitasking/background processing and html5 in the browser. Add that as well as acceptance in the marketplace and I'll be more interested in the device. Obviosuly, I'm now working on a MonoDroid book . I own Android and iPhone/iOS devices.  I am currently working on some startup ideas and am exploring as much in that area as I can. For 2011, I'm planning on speaking at Android Developer's Conference (AnDevCon) and Mobile Connections.  I'm really excited about this. I have a couple of magazine articles coming out in 2011 on Android and iPhone development with the Mono technologies.is Mono "The Answer"? What's "The Question?" I think it will work for me.  It might work for you, it might not.  it depends on your situation.  Its the current horse that I am riding. I might find a better horse tomorrow. So, that's how I got here.  I'm in love with mobile.  Mobile native apps on the device as well as mobile web.  I'm into all this cool stuff.  Where are you at?

• Restoring android after ubuntu touch fails

  - by deimus

  I'm trying to restore android after playing around with ubuntu touch I follow exactly the same steps described the ubuntu's wiki page i.e. Download the factory image corresponding to your device's model and version (initial table has links). Ensure the device is connected and powered on. Extract the downloaded file and cd into the extracted directory. run adb reboot-bootloader run ./flash-all.sh (use sudo if lack of permissions on the workstation don't allow you to talk to the device). The archive is downloaded successfully, checked the sha1 checksum everything is ok. But the ./flash-all.sh fails like this sending 'bootloader' (2308 KB)... OKAY [ 0.513s] writing 'bootloader'...

• How to set Alpha value from pixel shader in SlimDX Direct3d9

  - by Yashwinder

  I am trying to set alpha value of color as color.a = 0.5f in my pixel shader but all the time it is giving an exception. I can set color.r, color.g, color.b but it is not allowing me to set color.a and throwing an exception D3DERR_INVALIDCALL: Invalid call (-2005530516). I have just created a direct3d9 device and assigned my pixel shader to it. My pixel shader code is as below sampler2D ourImage : register(s0); float4 main(float2 locationInSource : TEXCOORD) : COLOR { float4 color = tex2D( ourImage , locationInSource.xy); color.a = 0.2; return color; } I am creating my pixel shader as byte[] byteCode = GiveFxFile(transitionEffect.PixelShaderFileName); var shaderBytecode = ShaderBytecode.Compile(byteCode, "main", "ps_2_0", ShaderFlags.None); var pixelShader = new PixelShader(device, ShaderBytecode); _device.PixelShader=pixelShader; I have initialized my device as var _presentParams = new PresentParameters { Windowed = _isWindowedMode, BackBufferWidth = (int)SystemParameters.PrimaryScreenWidth, BackBufferHeight = (int)SystemParameters.PrimaryScreenHeight, // Enable Z-Buffer // This is not really needed in this sample but real applications generaly use it EnableAutoDepthStencil = true, AutoDepthStencilFormat = Format.D16, // How to swap backbuffer in front and how many per screen refresh BackBufferCount = 1, SwapEffect = SwapEffect.Copy, BackBufferFormat = _direct3D.Adapters[0].CurrentDisplayMode.Format, PresentationInterval = PresentInterval.Immediate, DeviceWindowHandle = _windowHandle }; _device = new Device(_direct3D, 0, DeviceType.Hardware, _windowHandle, deviceFlags | CreateFlags.Multithreaded, _presentParams);

• UEFI/GPT Win 7 Load Failure in Dual Boot and no GRUB2 [Ubuntu 12.04]

  - by cristian_jordache

  Configuration: MBB: ASRock X79 Extreme6 Win 7 installed on a INTEL 40GB SSD (GPT partitioned) Ubuntu 14.04 on a CORSAIR 30GB SSD (Ext4 and SWAP) I had Windows 7 installed previously in UEFI mode, using 3 partitions (GPT) and works fine if left alone. In UEFI BIOS settings I can see sometimes a "Windows Boot Manager" and other times (?) a "UEFI Intel" entry for INTEL HDD and Windows will boot properly selecting the one available at that time. I installed Ubuntu 14.04 after Win 7 w/o changing any UEFI BIOS settings and it works fine only if the BIOS is set w/ the Ubuntu partition as the first drive to boot, in AHCI mode. If both SSD drives are connected, the Win7 Intel boot drive can be chosen as first boot device but only as an "AHCI Intel drive" (No "Windows Boot Manager" nor "UEFI Intel device" options available in BIOS Boot menu) and Win7 will not load properly as long as the Ubuntu Crucial SSD is NOT PHYSICALLY DISCONNECTED. Windows will try, start booting for few seconds but will fail replacing Win7 logo and that startup animation with w/ the "old" white progress bar and then and will notify that there is a issue and prompt the user to try to Load Win 7 in Normal Mode again or try a Recovery Mode to fix it. If I let Windows INTEL HDD boot via BIOS/UEFI - Windows Boot manager selection, I may see the purple screen of Grub2 loaded for a while, but there's no selection for Ubuntu or Windows and/or then machine is not booting, showing a black screen and a small command prompt cursor blinking on top. So far the only option I see to have Ubuntu boot side by side w/ Win 7 is to reformat the Win7 SDD and set it boot in legacy BIOS mode with a MBR instead of GPT. Per my understanding this is a quite complex issue to fix (Rod Smith's answer was pretty helpful: UEFI boot on my Asus k52f) but any other suggestions are welcome. I find a bit odd that I can boot properly Windows7 SSD or an Ubuntu DVD using a DVD drive set in UEFI-BIOS in "AHCI mode" and w/ using "UEFI/Windows Boot Manager" booting option but I cannot boot a secondary SSD-HDD w/ Ubuntu having the same BIOS/UEFI Boot configuration. Looks like plugging the second SSD [the Ubuntu partition] is interfering with boot options in UEFI-BIOS.

• Friday Tips #33

  - by Chris Kawalek

  Happy Friday, everyone! Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines: VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox. The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer. We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it. Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info. See you next week! -Chris

• Canon MX870 printer only shows "Processing" on the status LCD

  - by Nick

  I had my Canon MX870 installed perfectly fine in 11.10, but since upgrading to 12.04, it no longer works. The printer is recognized in print settings and when I attempt to print a test page, the printer LCD displays a "Processing" message, but then it disappears and nothing happens. Here are my logs (note that printing did not succeed despite the access logs showing success): # /var/log/cups/access_log localhost - - [22/May/2012:12:29:35 -0400] "POST /printers/Canon-MX870 HTTP/1.1" 200 412 Print-Job successful-ok - # /var/log/cups/error_log W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-Gray..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-MX870-RGB..' already exists W [22/May/2012:12:25:51 -0400] failed to CreateDevice: org.freedesktop.ColorManager.AlreadyExists:device id 'cups-Canon-MX870' already exists

• Calculating Screen Resolutions Using WPF

  - by Jeff Ferguson

  WPF measures all elements in device independent pixels (DIPs). These DIPs equate to device pixels if the current display monitor is set to the default of 96 DPI. However, for monitors set to a DPI setting that is different than 96 DPI, then WPF DIPs will not correspond directly to monitor pixels. Consider, for example, the WPF properties SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth. If your monitor resolution is set to 1024 pixels wide by 768 pixels high, and your monitor is set to 96 DPI, then WPF will report the value of SystemParameters.PrimaryScreenHeight as 768 and the value of SystemParameters.PrimaryScreenWidth as 1024. No problem. This aligns nicely because the WPF device independent pixel value (96) matches your monitor's DPI setting (96). However, if your monitor is not set to display pixels at 96 DPI, then SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth will not return what you expect. The values returned by these properties may be greater than or less than what you expect, depending on whether or not your monitor's DPI value is less than or greater than 96. Since the SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth properties are WPF properties, their values are measured in WPF DIPs, rather than taking monitor DPI into effect. Once again: WPF measures all elements in device independent pixels (DIPs). To combat this issue, you must take your monitor's DPI settings into effect if you're looking for the monitor's width and height using the monitor's DPI settings. The handy code block below will help you calculate these values regardless of the DPI setting on your monitor: Window MainWindow = Application.Current.MainWindow; PresentationSource MainWindowPresentationSource = PresentationSource.FromVisual(MainWindow); Matrix m = MainWindowPresentationSource.CompositionTarget.TransformToDevice; DpiWidthFactor = m.M11; DpiHeightFactor = m.M22; double ScreenHeight = SystemParameters.PrimaryScreenHeight * DpiHeightFactor; double ScreenWidth = SystemParameters.PrimaryScreenWidth * DpiWidthFactor; The values of ScreenHeight and ScreenWidth should, after this code is executed, match the resolution that you see in the display's Properties window.

• Android development in Unreal with an existing project

  - by user1238929

  I am currently using an Unreal 3 project that has been targeted for multiple devices. Originally, it was targeted for iOS and now I want to try and build it for Android. The project is capable of doing it and I am in the process of testing it. I think I have everything I need in order to build it and launch it for an android device that I have set up and connected to my PC and is recognized by the Android SDK ABD. I am currently trying to build and launch the game through the Unreal Frontend but when I try, I am getting stuck at getting the Unreal Frontend to find my Android device as a platform to debug, like it would with a PC, Xbox360, or PS3. Right now, I am just trying to launch the game to see if I can get it to simply run on an Android device, I'm going to worry about the packaging later. So I have two questions: Am I on the right track in looking at the Unreal Frontend to cook and launch the project on Android or should I look somewhere else? How do I get Unreal to recognize my Android device as a platform to launch on? I would even settle for recognizing an emulator, but that seems even harder.

• WSDL-world vs CLR-world – some differences

  - by nmarun

  A change in mindset is required when switching between a typical CLR application and a web service application. There are some things in a CLR environment that just don’t add-up in a WSDL arena (and vice-versa). I’m listing some of them here. When I say WSDL-world, I’m mostly talking with respect to a WCF Service and / or a Web Service. No (direct) Method Overloading: You definitely can have overloaded methods in a, say, Console application, but when it comes to a WCF / Web Services application, you need to adorn these overloaded methods with a special attribute so the service knows which specific method to invoke. When you’re working with WCF, use the Name property of the OperationContract attribute to provide unique names. 1: [OperationContract(Name = "AddInt")] 2: int Add(int arg1, int arg2); 3:  4: [OperationContract(Name = "AddDouble")] 5: double Add(double arg1, double arg2); By default, the proxy generates the code for this as: 1: [System.ServiceModel.OperationContractAttribute( 2: Action="http://tempuri.org/ILearnWcfService/AddInt", 3: ReplyAction="http://tempuri.org/ILearnWcfService/AddIntResponse")] 4: int AddInt(int arg1, int arg2); 5: 6: [System.ServiceModel.OperationContractAttribute( 7: Action="http://tempuri.org/ILearnWcfServiceExtend/AddDouble", 8: ReplyAction="http://tempuri.org/ILearnWcfServiceExtend/AddDoubleResponse")] 9: double AddDouble(double arg1, double arg2); With Web Services though the story is slightly different. Even after setting the MessageName property of the WebMethod attribute, the proxy does not change the name of the method, but only the underlying soap message changes. 1: [WebMethod] 2: public string HelloGalaxy() 3: { 4: return "Hello Milky Way!"; 5: } 6:  7: [WebMethod(MessageName = "HelloAnyGalaxy")] 8: public string HelloGalaxy(string galaxyName) 9: { 10: return string.Format("Hello {0}!", galaxyName); 11: } The one thing you need to remember is to set the WebServiceBinding accordingly. 1: [WebServiceBinding(ConformsTo = WsiProfiles.None)] The proxy is: 1: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloGalaxy", 2: RequestNamespace="http://tempuri.org/", 3: ResponseNamespace="http://tempuri.org/", 4: Use=System.Web.Services.Description.SoapBindingUse.Literal, 5: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 6: public string HelloGalaxy() 7:  8: [System.Web.Services.WebMethodAttribute(MessageName="HelloGalaxy1")] 9: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloAnyGalaxy", 10: RequestElementName="HelloAnyGalaxy", 11: RequestNamespace="http://tempuri.org/", 12: ResponseElementName="HelloAnyGalaxyResponse", 13: ResponseNamespace="http://tempuri.org/", 14: Use=System.Web.Services.Description.SoapBindingUse.Literal, 15: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 16: [return: System.Xml.Serialization.XmlElementAttribute("HelloAnyGalaxyResult")] 17: public string HelloGalaxy(string galaxyName) 18:  You see the calling method name is the same in the proxy, however the soap message that gets generated is different. Using interchangeable data types: See details on this here. Type visibility: In a CLR-based application, if you mark a field as private, well we all know, it’s ‘private’. Coming to a WSDL side of things, in a Web Service, private fields and web methods will not get generated in the proxy. In WCF however, all your operation contracts will be public as they get implemented from an interface. Even in case your ServiceContract interface is declared internal/private, you will see it as a public interface in the proxy. This is because type visibility is a CLR concept and has no bearing on WCF. Also if a private field has the [DataMember] attribute in a data contract, it will get emitted in the proxy class as a public property for the very same reason. 1: [DataContract] 2: public struct Person 3: { 4: [DataMember] 5: private int _x; 6:  7: [DataMember] 8: public int Id { get; set; } 9:  10: [DataMember] 11: public string FirstName { get; set; } 12:  13: [DataMember] 14: public string Header { get; set; } 15: } 16: } See the ‘_x’ field is a private member with the [DataMember] attribute, but the proxy class shows as below: 1: [System.Runtime.Serialization.DataMemberAttribute()] 2: public int _x { 3: get { 4: return this._xField; 5: } 6: set { 7: if ((this._xField.Equals(value) != true)) { 8: this._xField = value; 9: this.RaisePropertyChanged("_x"); 10: } 11: } 12: } Passing derived types to web methods / operation contracts: Once again, in a CLR application, I can have a derived class be passed as a parameter where a base class is expected. I have the following set up for my WCF service. 1: [DataContract] 2: public class Employee 3: { 4: [DataMember(Name = "Id")] 5: public int EmployeeId { get; set; } 6:  7: [DataMember(Name="FirstName")] 8: public string FName { get; set; } 9:  10: [DataMember] 11: public string Header { get; set; } 12: } 13:  14: [DataContract] 15: public class Manager : Employee 16: { 17: [DataMember] 18: private int _x; 19: } 20:  21: // service contract 22: [OperationContract] 23: Manager SaveManager(Employee employee); 24:  25: // in my calling code 26: Manager manager = new Manager {_x = 1, FirstName = "abc"}; 27: manager = LearnWcfServiceClient.SaveManager(manager); The above will throw an exception saying: In short, this is saying, that a Manager type was found where an Employee type was expected! Hierarchy flattening of interfaces in WCF: See details on this here. In CLR world, you’ll see the entire hierarchy as is. That’s another difference. Using ref parameters: * can use ref for parameters, but operation contract should not be one-way (gives an error when you do an update service reference)   => bad programming; create a return object that is composed of everything you need! This one kind of stumped me. Not sure why I tried this, but you can pass parameters prefixed with ref keyword* (* terms and conditions apply). The main issue is this, how would we know the changes that were made to a ‘ref’ input parameter are returned back from the service and updated to the local variable? Turns out both Web Services and WCF make this tracking happen by passing the input parameter in the response soap. This way when the deserializer does its magic, it maps all the elements of the response xml thereby updating our local variable. Here’s what I’m talking about. 1: [WebMethod(MessageName = "HelloAnyGalaxy")] 2: public string HelloGalaxy(ref string galaxyName) 3: { 4: string output = string.Format("Hello {0}", galaxyName); 5: if (galaxyName == "Andromeda") 6: { 7: galaxyName = string.Format("{0} (2.5 million light-years away)", galaxyName); 8: } 9: return output; 10: } This is how the request and response look like in soapUI. As I said above, the behavior is quite similar for WCF as well. But the catch comes when you have a one-way web methods / operation contracts. If you have an operation contract whose return type is void, is marked one-way and that has ref parameters then you’ll get an error message when you try to reference such a service. 1: [OperationContract(Name = "Sum", IsOneWay = true)] 2: void Sum(ref double arg1, ref double arg2); 3:  4: public void Sum(ref double arg1, ref double arg2) 5: { 6: arg1 += arg2; 7: } This is what I got when I did an update to my service reference: Makes sense, because a OneWay operation is… one-way – there’s no returning from this operation. You can also have a one-way web method: 1: [SoapDocumentMethod(OneWay = true)] 2: [WebMethod(MessageName = "HelloAnyGalaxy")] 3: public void HelloGalaxy(ref string galaxyName) This will throw an exception message similar to the one above when you try to update your web service reference. In the CLR space, there’s no such concept of a ‘one-way’ street! Yes, there’s void, but you very well can have ref parameters returned through such a method. Just a point here; although the ref/out concept sounds cool, it’s generally is a code-smell. The better approach is to always return an object that is composed of everything you need returned from a method. These are some of the differences that we need to bear when dealing with services that are different from our daily ‘CLR’ life.

• Syslog/kernlog filling up with "did not claim interface N before use"

  - by Wayne Werner

  As I discovered when asking this question, it appears that demond_nscan is trying to use a device without claiming it. And it does it.... hundreds of time per second apparently. This makes kern.log and syslog huge (100GB ). In this particular case the problem is directly a result of some Lexmark drivers that were installed (found at /usr/local/lexmark/unix_scan_drivers/bin/demond_nscan). Here are a few things I know: The drivers are for an all-in-one printer/scanner device. There was a previous lexmark printer-only that was installed with CUPS This driver was the one for CUPS systems, and I think that it automatically added it to the list of printers in CUPS. The issue started spamming kern/syslog only after these drivers were installed, using the lexmark installers While googling around I found this thread that's not completely related, but it does mention that it might be happening when two drivers try to control the same device at the same time. How can I resolve this issue so that either I only have one driver, or get the driver to claim the device before usage?

• precise dns problems after upgrading from lucid

  - by Jazzist

  I am having DNS problems since upgrading to Precise from Lucid yesterday. DNS sometimes works but is very slow. These problems are just like others are having but I'm wondering if someone can help as I have slightly different specifics. I have read this "I really don’t want a local resolver, how can I turn it off? To turn off dnsmasq in Network Manager, you need to edit /etc/NetworkManager/NetworkManager.conf and comment the “dns=dnsmasq” line (put a # in front of it) then do a “sudo restart network-manager”." I do not have this line to comment. Checking in Synaptic Package Manager reveals that dnsmasq isn't install (dnsmasq-base is). Editing / creating connections using network manager GUI (and specifying DNS servers) doesn't help; ubuntu is not respecting user GUI set DNS servers. Should these GUI tools not work? "I use static IP configuration, where should I put my DNS configuration? The DNS configuration for a static interface should go as “dns-nameservers”, “dns-search” and “dns-domain” entries added to the interface in /etc/network/interfaces" Are any examples of this available? My /etc/network/interfaces is extremely sparse. For now I have edited /etc/resolv.conf replacing nameserver 127.0.0.1 with that of my DNS server (my broadband router), but I don't know how long this fix will last before the file is overwritten by this new system (dnsmasq?).

• Encrypting a non-linux partition with LUKS.

  - by linuxn00b

  I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

• How to make Logitech Anywhere MX work in Ubuntu 12.X?

  - by alfC

  I have a Logitech Anywhere MX mouse (wireless), when I connect it to the computer it doesn't work. The mouse works in other computers with Windows and with Fedora 17, but it doesn't work in two different computers with Ubuntu 12.04 and 12.10. Moreover these same computers work with another Microsoft wireless mouse. So I think the combination of Logitech MX and Ubuntu doesn't play well. The dmesg log entry looks like this: [ 578.845838] usb 3-2: Product: USB Receiver [ 578.845841] usb 3-2: Manufacturer: Logitech [ 578.851625] logitech-djreceiver 0003:046D:C52B.0009: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-2/input2 [ 578.851899] logitech-djreceiver 0003:046D:C52B.0009: logi_dj_probe:logi_dj_recv_query_paired_devices error:-32 [ 578.854518] logitech-djreceiver: probe of 0003:046D:C52B.0009 failed with error -32 Instead of the expected (taken from Fedora): [154344.634520] usb 2-1.2: Manufacturer: Logitech [154344.647935] logitech-djreceiver 0003:046D:C52B.000D: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:1d.0-1.2/input2 [154344.653788] input: Logitech Unifying Device.

• Configure Dual Boot, Windows 7 and Ubuntu 12.04 with or without EFI

  - by Keroak

  I have just installed Ubuntu 12.04 on a laptop with Windows 7 but I don't get to boot from Ubuntu. First, during the installation I made these partitions (may be too many): /dev/sda1 FAT32 SYSTEM 200Mb boot (EFI boot, i guess) /dev/sda2 unknown file system 128 Mb msftres (Windows Boot Manager) /dev/sda3 NTFS OS 100 Gb (Windows 7) /dev/sda4 NTFS DATOS 315 Gb (Data partition) /dev/sda5 ext4 28 Gb (/home) /dev/sda8 unknown file system 1 Gb biog_grub (i'm not very sure why i made this one) /dev/sda6 ext4 17 Gb (/ Ubuntu 12.03 installed withou errors aparently) /dev/sda7 linex-swap 2 GB (swap) I can boot from Windows perfectly. Actually I tried to configure Windows Boot Manager with EasyBCD but it doesn't recognize any boot entry. Anyway, I added an Ubuntu Entry and it configured it automatically. Now I have boot entries the Windows 7 one that appear to work and the Ubuntu 12.04 that it prompt a "No application found" message. I re-started from a USB with Ubuntu and tried to fix GRUB from the command-line and with boot-repair. No results. As far as I understand I have to tell the Windows Boot Manager where my Ubuntu boot loader is. So I have two problems: Actually, I don't know where my Ubuntu boot loader, GRUB or GRUB2 or whatever, is. I don't know how to set my Ubuntu entry in Windows Boot Manager. I guess using BCDedit.exe as EasyBCD didn't show me the entries. Anyway, I don't know what parameters to use. I read several articles about it but i didn't find out anything useful.
