• Making WIF local STS to work with your ASP.NET application

  - by DigiMortal

  Making Windows Identity Foundation (WIF) STS test application work with your solution is not as straightforward process as you can read from books and articles. There are some tricks and some configuration modifications you must do to get things work. Fortunately these steps are simple one. 1. Move your application to IIS or IIS Express If your application uses development web server that ships with Visual Studio then make your application use IIS or IIS Express. You get simple support for IIS Express to Visual Studio 2010 after installing Visual Studio 2010 SP1. You can read more from my blog posting Visual Studio 2010 SP1 Beta supports IIS Express. NB! You don’t have to move your dummy STS project to IIS. 2. Change request validation mode to ASP.NET 2.0 As a next thing you will get the following error when coming back from dummy STS service: HttpRequestValidationException (0x80004005): A potentially dangerous Request.Form value was detected from the client. Open web.config of your application and add the following line before </system.web>: <httpRuntime requestValidationMode="2.0" /> Now you are done with configuring web application to work with STS.

• How can I validate if a 13.10 update was complete?

  - by James

  I attempted to upgrade Ubuntu 13.04 server to 13.10 tonight via the standard linux text console and it had some trouble. Machine boots and displays 13.10, but I am unsure exactly what or how much was successfully upgraded. Is there some command I can run which will validate that all system has all standard binaries upgraded to the 13.10 release? As for the issue .... everything seemed to be going along ok until the screen displayed some kind of menu option regarding local edits to samba config file. There was a prompt requesting root password or ctrl-d to continue, but it would not take any input. From another terminal screen I tried killing the process displaying this samba message, and then some screen/SCREEN processes. The hard drive activity picked up for a while and then all the processes on that pty were gone. As I said, reboot was OK, but I have no idea if everything was upgraded. The machine seems to be acting like normal, except that the upgrade killed my openpvn process which I'll need to reload. Thanks

• Designing Content-Based ETL Process with .NET and SFDC

  - by Patrick

  As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { // Upload using some wrapper for an ORM an someInterface.Upload(meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

• Nvidia 740M still not working after Bumblebee installation

  - by Jon

  first of all, I have checked a lot of similar topics, but I still can't get my laptop to use Nvidia 740M. So first things first. I have a laptop Asus X550V(i5-3230, 4gb RAM, Nvidia 740M + Intel HD4000). I installed Ubuntu 13.10 alongside Win8(preinstalled) and both systems are running without problems. However, I have problem with second graphic card(Nvidia 740M), as Ubuntu doesn't recognize it. I installed bumblebee with this tutorial https://wiki.ubuntu.com/Bumblebee#Installation, but I still get error "Cannot access secondary GPU" error when trying to run ''optirun Steam'' in terminal. Then I tried to do this: [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. you need to edit the /etc/bumblebee/xorg.conf.nvidia (or /etc/bumblebee/xorg.conf.nouveau if using the noveau driver) and specify the correct BusID by following the instructions therein. But with lspci / VGA i get only info about Intel 4000, but no Nvidia. When I type only lspci, I get the line for Nvidia 740M,but after I edit the config file I still get second card error. Also, in /etc/bumblebee/xorg.conf.nvidia there wasn't BusID or anything similar, so I just added the whole line in device section. As I sad, I tried a lot of things to get it working, avoiding this forum(as I din't want to bother people with some solutions possible), but alas!, I had to bother you. If there is a need for some additional info, just say, no problem at all. Thank you very much in advance. :)

• Invalid Html Response and JS Errors when you open your Application in Visual Studio 2013

  - by imran_ku07

   I was working on an application which uses Telerik controls. The application was working fine for a while. Suddenly, the application stopped working. I mean lot of my application pages becoming very very ugly. I found JavaScript errors on every Browser's console. When I check the page view-source, the generated HTML was messy and invalid. This was only happening with my local machine. If someone else on my network accesses my application pages, he will get the correct HTML and no JavaScript errors. My mind was blowing because the same page was generating invalid HTML(and JavaScript errors) when I access the page using a local browser but generate correct HTML(and no JavaScript errors) when someone else access my application page remotely. Then I realized that I the only change I made last was opening my application in Visual Studio 2013 RTM which I installed few days ago. I closed the Visual Studio 2013, everything work like a charm. Then I became100% sure that this is only happening due to new Visual Studio 2013 feature called Browser Link. I just open the application again and add this in web.config. Everything become fine Happy coding :)   <add key="vs:EnableBrowserLink" value="false" />

• How to make Unity 3D work with Bumblebee using the Intel chipset

  - by EboMike

  I have a Sony VAIO S laptop with the dreaded Optimus and finally managed to get Bumblebee to work fully on Ubuntu 12.04 so that I can utilize both the hardware acceleration of the Intel chipset as well as the Nvidia one via optirun and/or bumble-app-settings. However, the desktop effects don't work. But they should, I vaguely remember that they worked for a while before I had Bumblebee installed. This is what I get with the support test: :~$ /usr/lib/nux/unity_support_test -p Xlib: extension "NV-GLX" missing on display ":0". OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL version string: 1.4 (2.1 Mesa 8.0.2) Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: no GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no First of all, I kind of doubt that the chipset doesn't support VBOs (essentially a standard feature in GL). Neither Xorg.0.log nor Xorg.8.log show any particular errors. As for the Nvidia drivers: In order to get them to work, I had to install the 304.22 drivers (older ones wouldn't work). They clobbered libglx.so, so I reinstated the xserver-xorg-core libglx.so in its original place, moved Nvidia's libglx.so to an nvidia-specific folder and specified that folder in the bumblebee.config. That seems to work and shouldn't cause the problem I see here. For fun, I tried to use the Nvidia chipset for Unity, but that didn't fly either: ~$ optirun /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GT 640M LE/PCIe/SSE2 OpenGL version string: 4.2.0 NVIDIA 304.22 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no

• How do I change Clementine's play/pause indicator icons?

  - by MHC

  This is how the Clementine indicator displays play/pause: It's a minor detail, but I feel that the play and pause icons just don't go with the monochrome design of the panel. In order to change them I tried to locate all files associated with clementine, but to no avail. Here's the output: /home/user/.config/Clementine/clementine.db /usr/bin/clementine /usr/share/app-install/desktop/clementine:clementine.desktop /usr/share/app-install/icons/application-x-clementine.png /usr/share/applications/clementine.desktop /usr/share/doc/clementine /usr/share/doc/clementine/README.Debian /usr/share/doc/clementine/changelog.Debian.gz /usr/share/doc/clementine/copyright /usr/share/icons/hicolor/64x64/apps/application-x-clementine.png /usr/share/icons/hicolor/scalable/apps/application-x-clementine.svg /usr/share/icons/ubuntu-mono-dark/apps/24/clementine-panel-grey.png /usr/share/icons/ubuntu-mono-dark/apps/24/clementine-panel.png /usr/share/icons/ubuntu-mono-light/apps/24/clementine-panel-grey.png /usr/share/icons/ubuntu-mono-light/apps/24/clementine-panel.png /usr/share/man/man1/clementine.1.gz /usr/share/menu/clementine /usr/share/pixmaps/clementine-16.xpm /usr/share/pixmaps/clementine.xpm /var/lib/dpkg/info/clementine.list /var/lib/dpkg/info/clementine.md5sums /var/lib/dpkg/info/clementine.postinst /var/lib/dpkg/info/clementine.postrm /var/lib/menu-xdg/applications/menu-xdg/X-Debian-Applications-Sound-clementine.desktop Can anyone tell me where to find these icons and how to change them?

• Upgrade from Linux Mint 12 to Kubuntu 12.04?

  - by MountainX

  Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

• OpenGL ES 2 on Android: native window

  - by ThreaderSlash

  According to OGLES specification, we have the following definition: EGLSurface eglCreateWindowSurface(EGLDisplay display, EGLConfig config, NativeWindowType native_window, EGLint const * attrib_list) More details, here: http://www.khronos.org/opengles/documentation/opengles1_0/html/eglCreateWindowSurface.html And also by definition: int32_t ANativeWindow_setBuffersGeometry(ANativeWindow* window, int32_t width, int32_t height, int32_t format); More details, here: http://mobilepearls.com/labs/native-android-api I am running Android Native App on OGLES 2 and debugging it in a Samsung Nexus device. For setting up the 3D scene graph environment, the following variables are defined: struct android_app { ... ANativeWindow* window; }; android_app* mApplication; ... mApplication=&pApplication; And to initialize the App, we run the commands in the code: ANativeWindow_setBuffersGeometry(mApplication->window, 0, 0, lFormat); mSurface = eglCreateWindowSurface(mDisplay, lConfig, mApplication->window, NULL); Funny to say is that, the command ANativeWindow_setBuffersGeometry behaves as expected and works fine according to its definition, accepting all the parameters sent to it. But the eglCreateWindowSurface does no accept the parameter mApplication-window, as it should accept according to its definition. Instead, it looks for the following input: EGLNativeWindowType hWnd; mSurface = eglCreateWindowSurface(mDisplay,lConfig,hWnd,NULL); As an alternative, I considered to use instead: NativeWindowType hWnd=android_createDisplaySurface(); But debugger says: Function 'android_createDisplaySurface' could not be resolved Is 'android_createDisplaySurface' compatible only for OGLES 1 and not for OGLES 2? Can someone tell if there is a way to convert mApplication-window? In a way that the data from the android_app get accepted to the window surface?

• autostart app with tag in awm

  - by nonsenz

  while giving awm a try i encounter some problems. i want to autostart some apps when awm is started with specific tags. here's the relevant config i use for that. first my tags with layouts: tags = { names = {"mail", "www", "video", "files", 5, 6, 7, 8, 9}, layout = {layouts[11], layouts[11], layouts[11], layouts[11], layouts[1], layouts[1], layouts[1], layouts[1], layouts[1]} } for s = 1, screen.count() do -- Each screen has its own tag table. tags[s] = awful.tag(tags.names, s, tags.layout) end now the app-autostart stuff: awful.util.spawn("chromium-browser") awful.util.spawn("firefox") awful.util.spawn("vlc") awful.util.spawn_with_shell("xterm -name files -e mc") awful.util.spawn_with_shell("xterm -name 5term") awful.util.spawn_with_shell("xterm -name 5term") awful.util.spawn_with_shell("xterm -name 5term") awful.util.spawn_with_shell("xterm -name 5term") awful.util.spawn_with_shell("xfce4-power-manager") i use xterm with the -name param to give them custom classes (for custom tags via rules). and now some rules to connect apps with tags: awful.rules.rules = { -- All clients will match this rule. { rule = { }, properties = { border_width = beautiful.border_width, border_color = beautiful.border_normal, focus = true, keys = clientkeys, buttons = clientbuttons } }, { rule = { class = "MPlayer" }, properties = { floating = true } }, { rule = { class = "pinentry" }, properties = { floating = true } }, { rule = { class = "gimp" }, properties = { floating = true } }, -- Set Firefox to always map on tags number 2 of screen 1. -- { rule = { class = "Firefox" }, -- properties = { tag = tags[1][2] } }, { rule = { class = "Firefox" }, properties = { tag = tags[1][2] } }, { rule = { class = "Chromium-browser" }, properties = { tag = tags[1][1] } }, { rule = { class = "Vlc"}, properties = { tag = tags[1][3] } }, { rule = { class = "files"}, properties = { tag = tags[1][4] } }, { rule = { class = "5term"}, properties = { tag = tags[1][5] } }, } it works for chromium, firefox and vlc but not for the xterms with the "-name" param. when i check the xterms after they started with xprop i can see: WM_CLASS(STRING) = "5term", "XTerm" i think that sould work, but the xterms are placed on the first workspace/tag.

• Samba new file ownership, permissions configuration

  - by Martin Melka

  I have recently installed Samba on my server. Now I have a question about permissions and how to set it up. Currently I mount the Samba shared drive to my laptop with this line in /etc/fstab: //<host>/share /mnt/melka-server-data/ cifs username=<usrname> password=<passwd> _netdev 0 0 This works, as I can read from the files and create them (as root). The problem is when I want to create files as a regular user. I always get a Permission Denied error. These are ll outputs of the mounted folder: magicmaster@magicmaster-kubuntu:/mnt$ ll total 8 drwxr-xr-x 3 root root 4096 lis 11 14:15 ./ drwxr-xr-x 26 root root 4096 ríj 26 11:01 ../ drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 melka-server-data/ and the inside: magicmaster@magicmaster-kubuntu:/mnt/melka-server-data$ ll total 4 drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 ./ drwxr-xr-x 3 root root 4096 lis 11 14:15 ../ drwxrwxrwx 5 magicmaster magicmaster 0 lis 12 09:35 downloads/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 28 12:57 lost+found/ drwxrwxrwx 15 magicmaster magicmaster 0 lis 12 09:45 movies/ drwxrwxrwx 2 magicmaster magicmaster 0 lis 1 21:15 newest/ drwxrwxrwx 3 magicmaster magicmaster 0 lis 2 23:14 photos/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 30 12:44 software/ -rw-r--r-- 1 nobody nogroup 0 lis 12 22:12 zdar I called sudo chown -R magicmaster:magicmaster melka-server-data/ to try and change all the files to belong to me. Then the file zdar was created by magicmaster just by calling touch. I got the Permission Denied, but it was still created, though it belongs to nobody and I can't write into it. When I create a file as root, it still belongs to nobody, but at least I can write into it. What am I missing? I didn't notice anything in Samba config that would be related to this and I don't like the idea of having to log on as root in order to copy files.. Thanks

• Yet Another Way To Create An Object

  - by Ricardo Peres

  After I wrote this post, I come up with yet another way to create an object... Here it is: Stopwatch watch = new Stopwatch(); ConstructorInfo ci = typeof(StringBuilder).GetConstructor(new Type[0]); NewExpression expr = Expression.New(ci); Func<StringBuilder> func = Expression.Lambda(typeof(Func<StringBuilder>), expr).Compile() as Func<StringBuilder>; watch.Start(); for (Int32 i = 0; i < 100; ++i) { StringBuilder builder = func(); } Int64 time4 = watch.ElapsedTicks; watch.Reset(); I know of only one other way, which is by using CodeDOM. If you know of any other ways to create an object, let me know! SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

• nomachine NX: Text missing on all gtk interface (Unity and Gnome Classic)

  - by hansioux

  [Edit] I later realized my issue only occurs when I am using NX to remote access my machine. Therefore I edited the title and description. I have also found the temp solution, which is to "disable render extension" in the custom display settings. But doing so makes the NX experience very slow laggy, and not that nice to look at. [/EDIT] I did a fresh install on a new computer, and was trying to setup my fonts. When I log in remotely via NX, my the text are missing on all gtk based interfaces. That means most menues (except for unity), right click menues, applications themselves, terminal, and so on. About the only thing unaffected is firefox. all the texts are showing just fine for firefox. So that probably already says something about text permissions. I went to check if my fonts have the correct permissions and they do. I removed my custom settings from /etc/fonts/config.d, and still the texts are missing. There is a work around by using "disable render extension" in the custom display settings. How do I fix this issue permanently?

• XF86 keybinds in Openbox

  - by vasa1

  Lubuntu uses Openbox as its window manager. ~/.config/openbox/lubuntu-rc.xml is a file that specifies, among other things, keybinds for various commands. Most of the keybinds in lubuntu-rc.xml use modifier keys such as Control, Shift, Alt, and Super. For example, one way of opening a terminal window would be by pressing Control+Alt+T together: <!-- Launch a terminal on Ctrl + Alt + T--> <keybind key="C-A-T"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> But there is also this: <!-- Keybinding for terminal button--> <keybind key="XF86WWW"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> <keybind key="XF86Terminal"> <action name="Execute"> <command>lxsession-default terminal</command> </action> </keybind> What are keybind key="XF86WWW" and keybind key="XF86Terminal"? How do I locate these keys on my laptop's keyboard? My laptop is a Dell Inspiron N 1545 from 2008.

• Cat 6 Only 100mbit speed

  - by Stu2000

  I tried two different cat6 cables directly connected between my two ubuntu machines. This one I ordered online: http://www.amazon.co.uk/gp/product/B002SQPDXS/ref=wms_ohs_product only achieves 100mbit speeds, but does appear to be supporting cross-talk (direct pc to pc), the other cat 6 cable, worked perfectly and gets the full 1gigabit speed. Both tests were performed using ftp and checking the network monitor with direct pc to pc connection. Did the product from amazon lie to me or do I need to manually set a setting somewhere in ubuntu for some cables? I had thought 10 quid for 20m of gigabit ethernet cable was a bit cheap, you get what you pay for... Regards, Stu Update: It seems that after rebooting, the device is set to 1000mbit sec when looking it up with sudo ethtool eth0 However after a while, this will drop down to just 100, after which to reset it to 1000 again, I have to reboot, and simply unpugging and re-plugging in the cable doesn't do it. I tried setting this in networking config file as suggested here: auto eth0 iface eth0 inet static pre-up /usr/sbin/ethtool -s eth0 speed 1000 duplex full but that resulted in my networking failing to start. Is there a problem with my 'auto-negotiation' or something? Can I manually override a setting to 1000mbit?

• PHP not working with hosting

  - by Richard

  I have been playing with a php CMS site for someone that I am ready to deploy but am running into a couple problems that I assume to be hosting related. I have been developing and playing with it localy and deploying to a hosting environment friendly towards this specific CMS (joomla). I have recently been trying to deploy to a client's hosting and have been running in to some trouble. Any help would be greatly appreciated. I have been in contact with the clients hosting and have had them set up a mysql DB for me and enable php. Simple php was working but joomla was not able to create the config files it needed to run on this hosting. Therefore I havnt been able to successfully deploy my work. While playing around with some simple php pages I have started getting http 500 errors and now cant seem to get anywhere. This is a smaller hosting company that seems willing to work with me but I dont really know what i need to ask from them to get me working. My questions to you webmaster geniuses would be as follows: Given the situation I have described, is there anything specifically i should do to get my joomla/php site running on this hosting? What specifically should I ask my current hosting providers to do to help me get working? Thanks

• Changing State in PlayerControler from PlayerInput

  - by Jeremy Talus

  In my player input I wanna change the the "State" of my player controller but I have some trouble to do it my player input is declared like that : class ResistancePlayerInput extends PlayerInput within ResistancePlayerController config(ResistancePlayerInput); and in my playerControler I have that : class ResistancePlayerController extends GamePlayerController; var name PreviousState; DefaultProperties { CameraClass = class 'ResistanceCamera' //Telling the player controller to use your custom camera script InputClass = class'ResistanceGame.ResistancePlayerInput' DefaultFOV = 90.f //Telling the player controller what the default field of view (FOV) should be } simulated event PostBeginPlay() { Super.PostBeginPlay(); } auto state Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 200; `log("Player Walking"); } } state Running extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 350; `log("Player Running"); } } state Sprinting extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 800; `log("Player Sprinting"); } } I have tried to use PCOwner.GotoState(); and ResistancePlayerController(PCOwner).GotoState(); but won't work. I have also tried a simple GotoState, and nothing happen how can I call GotoState for the PC Class from my player input ?

• Differences when Running with OutputCache managed module under ASP.NET IIS7.x with Cache-control header

  - by Shawn Cicoria

  This post is to report some differences when using MVC or IHttpHandlers if you’re attempting to set the Cache-control : max-age or s-maxage value under IIS7.x using the HttpResponse.Cache methods. [UPDATE]: 2011-3-14 – The missing piece was calling  Response.Cache.SetSlidingExpiration(true) as follows: context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; context.Response.Cache.SetSlidingExpiration(true);   Under IIS7.x if you us one of the following 2 methods, you will only get a Cache-ability of “public”.  public ActionResult Image2() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("Respone.Cache.Setxx calls", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); return new FileStreamResult(oStream, "image/jpeg"); } } Method 2 – which is just a plain old HttpHandler and really isn’t MVC3, but under the same MVC ASP.NET application, same result. public class image : IHttpHandler { public void ProcessRequest(HttpContext context) { using (var image = ImageUtil.RenderImage("called from IHttpHandler direct", 5, DateTime.Now)) { context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; image.Save(context.Response.OutputStream, ImageFormat.Jpeg); } } } Using the following under MVC3 (I haven’t tried under earlier versions) will work by applying the OutputCacheAttribute to your Action: [OutputCache(Location = OutputCacheLocation.Any, Duration = 300)] public ActionResult Image1() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("called with OutputCacheAttribute", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; return new FileStreamResult(oStream, "image/jpeg"); } } To remove the “OutputCache” module, you use the following in your web.config: <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules runAllManagedModulesForAllRequests="true"> <!--<remove name="OutputCache"/>--> </modules>

• XSF-FO intellisense and national languages with Apache FOP

  - by Lukasz Kurylo

  Some time ago I showed how to get an intellisense and how to configure the FO.NET to acquire national characters inside the generated pdf files. Due to the limitations that I mensioned in my previous post, I started playing with the Apache FOP. In this post I want to show, how to acquire the same result as I showed in the two posts related to FO.NET.   Intellisense   To get the intellisense from the XSL-FO templates set the xsi:schemaLocation the same way I showed it in this post. The only diffrence to FO.NET is that, during generating the document by the code I showed last time we will get an exception:   org.apache.fop.fo.ValidationException: Invalid property encountered on "fo:root": xsi:schemaLocation (See position 6:11)   Fortunatelly there is a very easy way to resolve this without removing the entire attribute along with the intellisense. Add to the FopFactory the ignoreNamespace by:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.ignoreNamespace(http://www.w3.org/2001/XMLSchema-instance);   Notice that, the url specified in this method this is a namespace for the xmlns:xsi namespace, not xsi.schemaLocation.   Fonts / national characters   This point is a little dfferent to acquire, but not more complicated that it was with FO.NET. To set the fonts in Apache FOP 1.0, we need a configuration file. A sample one can be get from the directory where we unpacked the fop binaries, from conf subdirectory. There is a file called fop.xconf. We must copy this file to our solution. In the simplest way, in the <fonts> tag we can add  <auto-detect/>. Thanks to this, FOP will index all fonts available on the installed operating system. There probably should be no problem, if we have a http handler or a WCF Service on the server that serves the generated pdf documents. In this situation we can use all available fonts on this server.   To use this config file, we must set a path to it:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.setUserConfig(new File("fop.xconf"));

• Why does video playback lag/freeze when I go into full-screen mode?

  - by RanRag

  When I try to play my video files in SMPlayer it works fine but as soon as I switch to fullscreen mode(16:9) following thing happens: 1) Video starts lagging. 2) Audio and video goes out of sync. 3) CPU usage rises to ~50%. 4) SMPlayer starts to hang. My current SMPlayer configuration: 1)Video Output Driver = x11(slow) 2)Audio Output Driver = alsa(0.0-HDA Intel) 3)Cache = 8192 KB 4)Threads for decoding(MPEG-1/2 and H.264 only = 2 Things I tried solve this problem: 1) Tried changing video o/p driver to xv,gl. 2) Tried changing audio o/p driver to pulse. 3) Tried increasing cache size and also tried using nocache. Everything works fine on windows but I don't want to switch to windows just to play video files. My system config: Acer Aspire One D270 Atom N2600(Cedar Trail) 1.6GHz 2GB Memory Intel GMA 3600 graphics. Ubuntu 12.04 Kernel Release: 3.2.0-23-generic-pae Rest all things are working fine I have no resolution issue, bluetooth, wireless also working fine.
