Errors when installing Open Office

- by user109036

I followed the first set of instructions on this page to install Open Office: How to install Open Office? However, the last step which says to change the CHMOD of a folder, I got an error saying that the directory does not exist. Open Office now appears in my Ubuntu start menu, but clicking on it does nothing. I tried a reboot. Below is what I could copy from my terminal. I am running the latest Ubuntu. I have not uninstalled Libreoffice as suggested somewhere. The reason is that in the Ubuntu software centre, Libre office appears to be made up of several components and I don't know which ones to remove (or all maybe?). They are Libreoffice Draw, Math, Writer, Calc. After this operation, 480 MB of additional disk space will be used.

Blender mesh mirroring screws up normals when importing in Unity

- by Shivan Dragon

My issue is as follows: I've modeled a robot in Blender 2.6. It's a mech-like biped or if you prefer, it kindda looks like a chicken. Since it's symmetrical on the XZ plane, I've decided to mirror some of its parts instead of re-modeling them. Problem is, those mirrored meshes look fine in Blender (faces all show up properly and light falls on them as it should) but in Unity faces and lighting on those very same mirrored meshes is wrong. What also stumps me is the fact that even if I flip normals in Blender, I still get bad results in Unity for those meshes (though now I get different bad results than before). Here's the details: Here's a Blender screen shot of the robot. I've took 2 pictures and slightly rotated the camera around so the geometry in question can be clearly seen: Now, the selected cog-wheel-like piece is the mirrored mesh obtained from mirroring the other cog-wheel on the other (far) side of the robot torso. The back-face culling is turned of here, so it's actually showing the faces as dictated by their normals. As you can see it looks ok, faces are orientated correctly and light falls on it ok (as it does on the original cog-wheel from which it was mirrored). Now if I export this as fbx using the following settings: and then import it into Unity, it looks all screwy: It looks like the normals are in the wrong direction. This is already very strange, because, while in Blender, the original cog-wheel and its mirrored counter part both had normals facing one way, when importing this in Unity, the original cog-wheel still looks ok (like in Blender) but the mirrored one now has normals inverted. First thing I've tried is to go "ok, so I'll flip normals in Blender for the mirrored cog-wheel and then it'll display ok in Unity and that's that". So I went back to Blender, flipped the normals on that mesh, so now it looks bad in Blender: and then re-exported as fbx with the same settings as before, and re-imported into Unity. Sure enough the cog-wheel now looks ok in Unity, in the sense where the faces show up properly, but if you look closely you'll notice that light and shadows are now wrong: Now in Unity, even though the light comes from the back of the robot, the cog-wheel in question acts as if light was coming from some-where else, its faces which should be in shadow are lit up, and those that should be lit up are dark. Here's some things I've tried and which didn't do anything: in Blender I tried mirroring the mesh in 2 ways: first by using the scale to -1 trick, then by using the mirroring tool (select mesh, hit crtl-m, select mirror axis), both ways yield the exact same result in Unity I've tried playing around with the prefab import settings like "normals: import/calculate", "tangents: import/calculate" I've also tired not exporting as fbx manually from Blender, but just dropping the .blend file in the assets folder inside the Unity project So, my question is: is there a way to actually mirror a mesh in Blender and then have it imported in Unity so that it displays properly (as it does in Blender)? If yes, how? Thank you, and please excuse the TL;DR style.

How to fix “Microsoft SharePoint is not supported with version 4.0.30319.225 of the Microsoft .Net Runtime” in PowerGUI

- by ybbest

Today, when I try to run some PowerShell command against SharePoint in PowerGUI , I encounter some error message as below: Problem: Remove-SPSite : Microsoft SharePoint is not supported with version 4.0.30319.225 of the Microsoft .Net Runtime. At C:\SiteCreation.ps1:37 char:14 + CategoryInfo : InvalidData: (Microsoft.Share…mdletRemoveSite:SPCmdletRemoveSite) [Remove-SPSite], PlatformNotSupportedException Analysis: The error message is pretty clear that PowerGUI try to run the PowerShell command under .Net version 4.0 which is not supported by SharePoint2010, SharePoint2010 only support .Net 3.5.So how can I change the settings so that PowerShell does run under .Net3.5 in PowerGui? The solution is pretty easy. Solution: 1. Open your windows explorer and navigate to C:\Program Files (x86)\PowerGUI\ and open the configuration file ScriptEditor.exe.config. 2. Change the supportedRuntime version under Startup settings by removing the version=”v4.0″ as below From To 3. Restart your PowerGUI and rerun your script. It works like a charm.

Windows Azure AppFabric: ServiceBus Queue WPF Sample

- by xamlnotes

The latest version of the AppFabric ServiceBus now has support for queues and topics. Today I will show you a bit about using queues and also talk about some of the best practices in using them. If you are just getting started, you can check out this site for more info on Windows Azure. One of the 1st things I thought if when Azure was announced back when was how we handle fault tolerance. Web sites hosted in Azure are no much of an issue unless they are using SQL Azure and then you must account for potential fault or latency issues. Today I want to talk a bit about ServiceBus and how to handle fault tolerance. And theres stuff like connecting to the servicebus and so on you have to take care of. To demonstrate some of the things you can do, let me walk through this sample WPF app that I am posting for you to download. To start off, the application is going to need things like the servicenamespace, issuer details and so forth to make everything work. To facilitate this I created settings in the wpf app for all of these items. Then I mapped a static class to them and set the values when the program loads like so: StaticElements.ServiceNamespace = Convert.ToString(Properties.Settings.Default["ServiceNamespace"]); StaticElements.IssuerName = Convert.ToString(Properties.Settings.Default["IssuerName"]); StaticElements.IssuerKey = Convert.ToString(Properties.Settings.Default["IssuerKey"]); StaticElements.QueueName = Convert.ToString(Properties.Settings.Default["QueueName"]); Now I can get to each of these elements plus some other common values or instances directly from the StaticElements class. Now, lets look at the application. The application looks like this when it starts: The blue graphic represents the queue we are going to use. The next figure shows the form after items were added and the queue stats were updated . You can see how the queue has grown: To add an item to the queue, click the Add Order button which displays the following dialog: After you fill in the form and press OK, the order is published to the ServiceBus queue and the form closes. The application also allows you to read the queued items by clicking the Process Orders button. As you can see below, the form shows the queued items in a list and the queue has disappeared as its now empty. In real practice we normally would use a Windows Service or some other automated process to subscribe to the queue and pull items from it. I created a class named ServiceBusQueueHelper that has the core queue features we need. There are three public methods: * GetOrCreateQueue – Gets an instance of the queue description if the queue exists. if not, it creates the queue and returns a description instance. * SendMessageToQueue = This method takes an order instance and sends it to the queue. The call to the queue is wrapped in the ExecuteAction method from the Transient Fault Tolerance Framework and handles all the retry logic for the queue send process. * GetOrderFromQueue – Grabs an order from the queue and returns a typed order from the queue. It also marks the message complete so the queue can remove it. Now lets turn to the WPF window code (MainWindow.xaml.cs). The constructor contains the 4 lines shown about to setup the static variables and to perform other initialization tasks. The next few lines setup certain features we need for the ServiceBus: TokenProvider credentials = TokenProvider.CreateSharedSecretTokenProvider(StaticElements.IssuerName, StaticElements.IssuerKey); Uri serviceUri = ServiceBusEnvironment.CreateServiceUri("sb", StaticElements.ServiceNamespace, string.Empty); StaticElements.CurrentNamespaceManager = new NamespaceManager(serviceUri, credentials); StaticElements.CurrentMessagingFactory = MessagingFactory.Create(serviceUri, credentials); The next two lines update the queue name label and also set the timer to 20 seconds. QueueNameLabel.Content = StaticElements.QueueName; _timer.Interval = TimeSpan.FromSeconds(20); Next I call the UpdateQueueStats to initialize the UI for the queue: UpdateQueueStats(); _timer.Tick += new EventHandler(delegate(object s, EventArgs a) { UpdateQueueStats(); }); _timer.Start(); } The UpdateQueueStats method shown below. You can see that it uses the GetOrCreateQueue method mentioned earlier to grab the queue description, then it can get the MessageCount property. private void UpdateQueueStats() { _queueDescription = _serviceBusQueueHelper.GetOrCreateQueue(); QueueCountLabel.Content = "(" + _queueDescription.MessageCount + ")"; long count = _queueDescription.MessageCount; long queueWidth = count * 20; QueueRectangle.Width = queueWidth; QueueTickCount += 1; TickCountlabel.Content = QueueTickCount.ToString(); } The ReadQueueItemsButton_Click event handler calls the GetOrderFromQueue method and adds the order to the listbox. If you look at the SendQueueMessageController, you can see the SendMessage method that sends an order to the queue. Its pretty simple as it just creates a new CustomerOrderEntity instance,fills it and then passes it to the SendMessageToQueue. As you can see, all of our interaction with the queue is done through the helper class (ServiceBusQueueHelper). Now lets dig into the helper class. First, before you create anything like this, download the Transient Fault Handling Framework. Microsoft provides this free and they also provide the C# source. Theres a great article that shows how to use this framework with ServiceBus. I included the entire ServiceBusQueueHelper class in List 1. Notice the using statements for TransientFaultHandling: using Microsoft.AzureCAT.Samples.TransientFaultHandling; using Microsoft.AzureCAT.Samples.TransientFaultHandling.ServiceBus; The SendMessageToQueue in Listing 1 shows how to use the async send features of ServiceBus with them wrapped in the Transient Fault Handling Framework. It is not much different than plain old ServiceBus calls but it sure makes it easy to have the fault tolerance added almost for free. The GetOrderFromQueue uses the standard synchronous methods to access the queue. The best practices article walks through using the async approach for a receive operation also. Notice that this method makes a call to Receive to get the message then makes a call to GetBody to get a new strongly typed instance of CustomerOrderEntity to return. Listing 1 using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.AzureCAT.Samples.TransientFaultHandling; using Microsoft.AzureCAT.Samples.TransientFaultHandling.ServiceBus; using Microsoft.ServiceBus; using Microsoft.ServiceBus.Messaging; using System.Xml.Serialization; using System.Diagnostics; namespace WPFServicebusPublishSubscribeSample { class ServiceBusQueueHelper { RetryPolicy currentPolicy = new RetryPolicy<ServiceBusTransientErrorDetectionStrategy>(RetryPolicy.DefaultClientRetryCount); QueueClient currentQueueClient; public QueueDescription GetOrCreateQueue() { QueueDescription queue = null; bool createNew = false; try { // First, let's see if a queue with the specified name already exists. queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.GetQueue(StaticElements.QueueName); }); createNew = (queue == null); } catch (MessagingEntityNotFoundException) { // Looks like the queue does not exist. We should create a new one. createNew = true; } // If a queue with the specified name doesn't exist, it will be auto-created. if (createNew) { try { var newqueue = new QueueDescription(StaticElements.QueueName); queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.CreateQueue(newqueue); }); } catch (MessagingEntityAlreadyExistsException) { // A queue under the same name was already created by someone else, // perhaps by another instance. Let's just use it. queue = currentPolicy.ExecuteAction<QueueDescription>(() => { return StaticElements.CurrentNamespaceManager.GetQueue(StaticElements.QueueName); }); } } currentQueueClient = StaticElements.CurrentMessagingFactory.CreateQueueClient(StaticElements.QueueName); return queue; } public void SendMessageToQueue(CustomerOrderEntity Order) { BrokeredMessage msg = null; GetOrCreateQueue(); // Use a retry policy to execute the Send action in an asynchronous and reliable fashion. currentPolicy.ExecuteAction ( (cb) => { // A new BrokeredMessage instance must be created each time we send it. Reusing the original BrokeredMessage instance may not // work as the state of its BodyStream cannot be guaranteed to be readable from the beginning. msg = new BrokeredMessage(Order); // Send the event asynchronously. currentQueueClient.BeginSend(msg, cb, null); }, (ar) => { try { // Complete the asynchronous operation. // This may throw an exception that will be handled internally by the retry policy. currentQueueClient.EndSend(ar); } finally { // Ensure that any resources allocated by a BrokeredMessage instance are released. if (msg != null) { msg.Dispose(); msg = null; } } }, (ex) => { // Always dispose the BrokeredMessage instance even if the send // operation has completed unsuccessfully. if (msg != null) { msg.Dispose(); msg = null; } // Always log exceptions. Trace.TraceError(ex.Message); } ); } public CustomerOrderEntity GetOrderFromQueue() { CustomerOrderEntity Order = new CustomerOrderEntity(); QueueClient myQueueClient = StaticElements.CurrentMessagingFactory.CreateQueueClient(StaticElements.QueueName, ReceiveMode.PeekLock); BrokeredMessage message; ServiceBusQueueHelper serviceBusQueueHelper = new ServiceBusQueueHelper(); QueueDescription queueDescription; queueDescription = serviceBusQueueHelper.GetOrCreateQueue(); if (queueDescription.MessageCount > 0) { message = myQueueClient.Receive(TimeSpan.FromSeconds(90)); if (message != null) { try { Order = message.GetBody<CustomerOrderEntity>(); message.Complete(); } catch (Exception ex) { throw ex; } } else { throw new Exception("Did not receive the messages"); } } return Order; } } } I will post a link to the download demo in a separate post soon.

BizTalk host throttling – Singleton pattern and High database size

- by S.E.R.

Originally posted on: http://geekswithblogs.net/SERivas/archive/2013/06/30/biztalk-host-throttling-ndash-singleton-pattern-and-high-database-size.aspxI have worked for some days around the singleton pattern (for those unfamiliar with it, read this post by Victor Fehlberg) and have come across a few very interesting posts, among which one dealt with performance issues (here, also by Victor Fehlberg). Simply put: if you have an orchestration which implements the singleton pattern, then performances will continuously decrease as the orchestration receives and consumes messages, and that behavior is more obvious when the orchestration never ends (ie : it keeps looping and never terminates or completes). As I experienced the same kind of problem (actually I was alerted by SCOM, which told me that the host was being throttled because of High database size), I thought it would be a good idea to dig a little bit a see what happens deep inside BizTalk and thus understand the reasons for this behavior. NOTE: in this article, I will focus on this High database size throttling condition. I will try and work on the other conditions in some not too distant future… Test conditions The singleton orchestration For the purpose of this study, I have created the following orchestration, which is a very basic implementation of a singleton that piles up incoming messages, then does something else when a certain timeout has been reached without receiving another message: Throttling settings I have two distinct hosts : one that hosts the receive port (basic FILE port) : Ports_ReceiveHostone that hosts the orchestration : ProcessingHost In order to emphasize the throttling mechanism, I have modified the throttling settings for each of these hosts are as follows (all other parameters are set to the default value): [Throttling thresholds] Message count in database: 500 (default value : 50000) Evolution of performance counters when submitting messages Since we are investigating the High database size throttling condition, here are the performance counter that we should take a look at (all of them are in the BizTalk:Message Agent performance object): Database sizeHigh database sizeMessage delivery throttling stateMessage publishing throttling stateMessage delivery delay (ms)Message publishing delay (ms)Message delivery throttling state durationMessage publishing throttling state duration (If you are not used to Perfmon, I strongly recommend that you start using it right now: it is a wonderful tool that allows you to open the hood and see what is going on inside BizTalk – and other systems) Database size It is quite obvious that we will start by watching the database size and high database size counters, just to see when the first reaches the configured threshold (500) and when the second rings the alarm. NOTE : During this test I submitted 600 messages, one message at a time every 10ms to see the evolution of the counters we have previously selected. It might not show very well on this screenshot, but here is what happened: From 15:46:50 to 15:47:50, the database size for the Ports_ReceiveHost host (blue line) kept growing until it reached a maximum of 504.At 15:47:50, the high database size alert fires At first I was surprised by this result: why is it the database size of the receiving host that keeps growing since it is the processing host that piles up messages? Actually, it makes total sense. This counter measures the size of the database queue that is being filled by the host, not consumed. Therefore, the high database size alert is raised on the host that fills the queue: Ports_ReceiveHost. More information is available on the Public MPWiki page. Now, looking at the Message publishing throttling state for the receiving host (green line), we can see that a throttling condition has been reached at 15:47:50: We can also see that the Message publishing delay(ms) (blue line) has begun growing slowly from this point. All of this explains why performances keep decreasing when a singleton keeps processing new messages: the database size grows and when it has exceeded the Message count in database threshold, the host is throttled and the publishing delay keeps increasing. Digging further So, what happens to the database queue then? Is it flushed some day or does it keep growing and growing indefinitely? The real question being: will the host be throttled forever because of this singleton? To answer this question, I set the Message count in database threshold to 20 (this value is very low in order not to wait for too long, otherwise I certainly would have fallen asleep in front of my screen) and I submitted 30 messages. The test was started at 18:26. At 18:56 (ie : exactly 30min later) the throttling was stopped and the database size was divided by 2. 30 min later again, the database size had dropped to almost zero: I guess I’ll have to find some documentation and do some more testing before I sort this out! My guess is that some maintenance job is at work here, though I cannot tell which one Digging even further If we take a look at the Message delivery throttling state counter for the processing host, we can see that this host was also throttled during the submission of the 600 documents: The value for the counter was 1, meaning that Message delivery incoming rate for the host instance exceeds the Message delivery outgoing rate * the specified Rate overdrive factor (percent) value. We will see this another day… :) A last word Let’s end this article with a warning: DO NOT CHANGE THE THROTTLING SETTINGS LIGHTLY! The temptation can be great to just bypass throttling by setting very high values for each parameter (or zero in some cases, which simply disables throttling). Nevertheless, always keep in mind that this mechanism is here for a very good reason: prevent your BizTalk infrastructure from exploding!! So whatever you do with those settings, do a lot of testing and benchmarking!

Add an Opera Style Status Bar to Firefox

- by Asian Angel

Anyone who has used Opera will be familiar with the information presented for the webpage that is currently loading in the browser (i.e. number of images loaded). If you would like to have that same functionality in Firefox then join us as we look at the Extended Statusbar extension. Before Here is the default setup for Firefox…not a lot of information available to indicate exactly how much of the webpage has already loaded versus what has not. For some people this is enough but what if you like more details? Extended Statusbar in Action You may be curious about the information that the Extended Statusbar extension will provide. The information includes: Percentage of the webpage loaded The number of images loaded Bytes downloaded Average download speed The load time After emptying the cache we once again reloaded the HTG homepage. The default style/mode is “Classic Style” and the “webpage load information” will be displayed within your “Status Bar” as shown here. The information available after the webpage finished loading in “Classic Style”. If you prefer “Slim Mode” this is how your “Status Bar” should look afterwards…very condensed. For those preferring the “New Style” a temporary addition will appear above your regular “Status Bar” and disappear just a few seconds after the webpage has fully loaded (unless changed in the “Settings”). Settings The “Settings” are set up in two different ways. For those who prefer to use the “Classic Style & Slim Mode” these are the options available to you. If you prefer the “New Style” then you will have a whole different set of options available. Notice that you can exclude certain webpages and set a custom style if desired. Conclusion If you have been wanting to add Opera style webpage loading information to your “Status Bar” then you should definitely give this extension a try.

"SASL authentication failed" with mutt and Gmail, why?

- by hhh

I am confused by this, I have installed a lot of new pkgs and followed some tutorials after googling but I keep getting this kind of SASL -err. I am not sure whether the mistake is in some Gmail settings or should I check some settings in Ubuntu? I thought this tutorial here would have solved this problem (i am simply trying to set up local mail reading with mutt, using gmail) but I cannot see the instructed things with telnet: "250-STARTTLS 250-AUTH PLAIN LOGIN" so that is why it is not working. $cat .muttrc set imap_user = "[email protected]" set imap_pass = "pass" #set smtp_url = "smtp://[email protected]:465/" set smtp_url = "smtp://[email protected]:587/" set smtp_pass = "pass" set from = "[email protected]" set realname = "name" set folder = "imaps://imap.gmail.com:993" set spoolfile = "+INBOX" set postponed="+[Gmail]/Drafts" set move = no

How to install Windows 8 to dual boot with Windows 7/XP?

- by Gopinath

Microsoft released Windows 8 beta(customer preview) few days ago and yesterday I had a chance to install it on one of my home computers. My home PC is running on Windows 7 and I would like to install Windows 8 side by side so that I can dual boot. The installation process was pretty simple and with in 40 minutes my PC was up and running with beautiful Windows 8 OS along with Windows 7. In this post I want to share my experience and provide information for you to install Windows 8. 1. Identify a drive with at least 20 GB of space – Identify one of the drives on your hard disk that can be used to install Windows 8. Delete all the files or preferably quick format it and make sure that it has at least 20 GB of free space. Rename the drive name to Windows 8 so that it will be helpful to identify the destination drive during installation process. 2. Download Windows 8 installer ISO– Go to Microsoft’s website and download Windows 8 ISO file which is approximately 2.5 GB file(32 bit English version). 3. Create Windows 8 bootable USB/DVD – Its advised to launch Windows 8 installer using a bootable USB or DVD for enabling dual boot instead of unzipping the ISO file and launching the setup from Windows 7 OS. Also consider creating bootable USB instead of bootable DVD to save a disc. To create bootable USB/DVD follow these steps Download and install the Windows 7 DVD / USB tool available at microsoftstore.com Launch the utility and follow the onscreen instructions where you would be asked to choose the ISO file(point to file downloaded in step 2) and choose a USB drive or DVD as destination. The onscreen instructions are very simple and you would be able to complete it in 20 minutes time. So now you have Windows 8 installation setup on your USB drive or DVD. 4. Change BIOS settings to boot from USB/DVD – Restart your PC and open BIOS configuration settings key by pressing F2 or F12 or DELETE key (the key depends on your computer manufacturer). Go to boot sequence options and make sure that USB/DVD is ahead of hard disk in the boot sequence. Save the settings and restart the PC. 5. Install Windows 8 – After the restart you should be straight into Windows 8 installation screen. Follow the onscreen instructions and install Windows 8 on the drive that is identified during step 1. When prompted for product serial key enter NF32V-Q9P3W-7DR7Y-JGWRW-JFCK8. The installer would restart couple of times during the installation process. On the first restart, make sure that you remove USB/DVD. Windows 8 installation process is pretty simple and very quick. The complete process of creating bootable USB and installation should complete in 30 – 40 minutes time.

Anti-Forgery Request in ASP.NET MVC and AJAX

- by Dixin

Background To secure websites from cross-site request forgery (CSRF, or XSRF) attack, ASP.NET MVC provides an excellent mechanism: The server prints tokens to cookie and inside the form; When the form is submitted to server, token in cookie and token inside the form are sent by the HTTP request; Server validates the tokens. To print tokens to browser, just invoke HtmlHelper.AntiForgeryToken():<% using (Html.BeginForm()) { %> <%: this.Html.AntiForgeryToken(Constants.AntiForgeryTokenSalt)%> <%-- Other fields. --%> <input type="submit" value="Submit" /> <% } %> which writes to token to the form:<form action="..." method="post"> <input name="__RequestVerificationToken" type="hidden" value="J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP" />  <input type="submit" value="Submit" /> </form> and the cookie: __RequestVerificationToken_Lw__=J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuP When the above form is submitted, they are both sent to server. [ValidateAntiForgeryToken] attribute is used to specify the controllers or actions to validate them:[HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult Action(/* ... */) { // ... } This is very productive for form scenarios. But recently, when resolving security vulnerabilities for Web products, I encountered 2 problems: It is expected to add [ValidateAntiForgeryToken] to each controller, but actually I have to add it for each POST actions, which is a little crazy; After anti-forgery validation is turned on for server side, AJAX POST requests will consistently fail. Specify validation on controller (not on each action) Problem For the first problem, usually a controller contains actions for both HTTP GET and HTTP POST requests, and usually validations are expected for HTTP POST requests. So, if the [ValidateAntiForgeryToken] is declared on the controller, the HTTP GET requests become always invalid:[ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public class SomeController : Controller { [HttpGet] public ActionResult Index() // Index page cannot work at all. { // ... } [HttpPost] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] public ActionResult PostAction2(/* ... */) { // ... } // ... } If user sends a HTTP GET request from a link: http://Site/Some/Index, validation definitely fails, because no token is provided. So the result is, [ValidateAntiForgeryToken] attribute must be distributed to each HTTP POST action in the application:public class SomeController : Controller { [HttpGet] public ActionResult Index() // Works. { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction1(/* ... */) { // ... } [HttpPost] [ValidateAntiForgeryToken(Salt = Constants.AntiForgeryTokenSalt)] public ActionResult PostAction2(/* ... */) { // ... } // ... } Solution To avoid a large number of [ValidateAntiForgeryToken] attributes (one attribute for one HTTP POST action), I created a wrapper class of ValidateAntiForgeryTokenAttribute, where HTTP verbs can be specified:[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class ValidateAntiForgeryTokenWrapperAttribute : FilterAttribute, IAuthorizationFilter { private readonly ValidateAntiForgeryTokenAttribute _validator; private readonly AcceptVerbsAttribute _verbs; public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs) : this(verbs, null) { } public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs, string salt) { this._verbs = new AcceptVerbsAttribute(verbs); this._validator = new ValidateAntiForgeryTokenAttribute() { Salt = salt }; } public void OnAuthorization(AuthorizationContext filterContext) { string httpMethodOverride = filterContext.HttpContext.Request.GetHttpMethodOverride(); if (this._verbs.Verbs.Contains(httpMethodOverride, StringComparer.OrdinalIgnoreCase)) { this._validator.OnAuthorization(filterContext); } } } When this attribute is declared on controller, only HTTP requests with the specified verbs are validated:[ValidateAntiForgeryTokenWrapper(HttpVerbs.Post, Constants.AntiForgeryTokenSalt)] public class SomeController : Controller { // Actions for HTTP GET requests are not affected. // Only HTTP POST requests are validated. } Now one single attribute on controller turns on validation for all HTTP POST actions. Submit token via AJAX Problem For AJAX scenarios, when request is sent by JavaScript instead of form:$.post(url, { productName: "Tofu", categoryId: 1 // Token is not posted. }, callback); This kind of AJAX POST requests will always be invalid, because server side code cannot see the token in the posted data. Solution The token must be printed to browser then submitted back to server. So first of all, HtmlHelper.AntiForgeryToken() must be called in the page where the AJAX POST will be sent. Then jQuery must find the printed token in the page, and post it:$.post(url, { productName: "Tofu", categoryId: 1, __RequestVerificationToken: getToken() // Token is posted. }, callback); To be reusable, this can be encapsulated in a tiny jQuery plugin:(function ($) { $.getAntiForgeryToken = function () { // HtmlHelper.AntiForgeryToken() must be invoked to print the token. return $("input[type='hidden'][name='__RequestVerificationToken']").val(); }; var addToken = function (data) { // Converts data if not already a string. if (data && typeof data !== "string") { data = $.param(data); } data = data ? data + "&" : ""; return data + "__RequestVerificationToken=" + encodeURIComponent($.getAntiForgeryToken()); }; $.postAntiForgery = function (url, data, callback, type) { return $.post(url, addToken(data), callback, type); }; $.ajaxAntiForgery = function (settings) { settings.data = addToken(settings.data); return $.ajax(settings); }; })(jQuery); Then in the application just replace $.post() invocation with $.postAntiForgery(), and replace $.ajax() instead of $.ajaxAntiForgery():$.postAntiForgery(url, { productName: "Tofu", categoryId: 1 }, callback); // Token is posted. This solution looks hard coded and stupid. If you have more elegant solution, please do tell me.

How to Change and Manually Start and Stop Automatic Maintenance in Windows 8

- by Lori Kaufman

Windows 8 has a new feature that allows you to automatically run scheduled daily maintenance on your computer. These maintenance tasks run in the background and include security updating and scanning, Windows software updates, disk defragmentation, system diagnostics, among other tasks. We’ve previously shown you how to automate maintenance in Windows 7, Vista, and XP. Windows 8 maintenance is automatic by default and the performance and energy efficiency has been improved over Windows 7. The program for Windows 8 automatic maintenance is called MSchedExe.exe and it is located in the C:\Windows\System32 directory. We will show you how you can change the automatic maintenance settings in Windows 8 and how you can start and stop the maintenance manually. NOTE: It seems that you cannot turn off the automatic maintenance in Windows 8. You can only change the settings and start and stop it manually. Can Dust Actually Damage My Computer?

Prevent Changing the Screen Saver and Wallpaper in Windows 7

- by Mysticgeek

Sometimes you might not want users to have the ability to change Screen Savers and Wallpaper on Windows 7 workstations. Today we look at how to prevent them from changing either one or both. You might administer computers in your home or small office and find it annoying when users continuously change the wallpaper and Screen Savers to something obnoxious. A lot of times they might be inexperienced users and download these so-called “wonderful and free” Screen Saver/Wallpaper packages from shady sites that include loads of Spyware. Preventing users from changing them is another helpful tool to avoid wasteful time spent switching things back. Prevent Changing Screensavers & Wallpaper Using Group Policy Editor Note: This method uses Group Policy which is not available in Home versions on Windows 7. Open the Start Menu and enter gpedit.msc into the Search box and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates \ Control Panel \ Personalization. Then in the right column double-click on Prevent changing desktop background. Now check the radio button next to Enabled, then click OK. Back on the Group Policy Screen, double-click on Prevent changing screen saver. In the next screen select the radio button next to Enable, click OK, then close out of Group Policy Editor. Now when a user goes into the Personalization section, the Desktop Background hyperlink is now grayed out and inactive. Notice the message One or more of the settings on this page has been disabled by the system administrator at the bottom of the section. If they click to change the Screen Saver, an error message will pop up letting them know the function is disabled. Prevent Changing Screensavers & Wallpaper Using a Registry Hack You can also make a couple Registry changes to prevent users from changing the Wallpaper & Screen Saver…which will work on Home versions of Windows 7. Before making any Registry changes make sure you back it up first. Open the Registry by typing regedit into the Search box in the Start menu and hit Enter. First we’ll start with the Wallpaper. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new String Value and name it Wallpaper. Then modify the Value data to point to the location of the Wallpaper you want it to always be. Where in this example it’s our main wallpaper on our local drive…then click OK. Now let’s make sure they can’t change the Screen Saver. In the same Registry location, we need to make a new DWORD (32-bit) Value. Give it the Value name of NoDispScrSavPage and the value data of “1” and click OK. Close out of the Registry and restart the machine or simply log off then back on again for the changes to take effect. Results For the Wallpapers, a user can still go in and see the selections, however if they try to change it to something else… It will just go back to the Personalization screen and no changes will be made, as we set the value to only be the background we specified. If the user tries to make a change to the Screen Saver, the hyperlink will be grayed out and inactive, and the message One or more of the settings on this page has been disabled by the system administrator will be displayed at the bottom of the section. Conclusion If you’re tired of users changing the Wallpaper and Screen Saver, and want another way to help avoid Malware, locking down these settings can help a lot. Again, before making any changes to the Registry, make sure to back it up. These settings should work in Vista and XP as well.

Doing Time Limited Flight Recordings Using Start Up Parameters

- by Marcus Hirt

Just like with the old JRockit Runtime Analyzer, it is possible to start up recordings using command line parameters to JRockit. The parameter is called -XX:StartFlightRecording in R28. Below is an example that starts a flight recording half a minute after the JVM has been started. The recording will last for a minute. The name when viewing the ongoing recordings will be MyRecording, and the resulting file will be written to C:\tmp\myrecording.jfr. The recording will use the settings in jre\lib\jfr\profile.jfs. -XX:StartFlightRecording=delay=30s,duration=60s,name=MyRecording,filename=C:\tmp\myrecording.jfr,settings=profile For more information, see the JRockit R28 command line parameter documentation.

Screen magnifier wrecks login screen — how to get rid of it?

- by Jonik

In the Ubuntu / GNOME login screen, I tried some of the different accessibility settings out of curiosity. Big mistake! Enabling the "use screen magnifier" (or whatever) option breaks down the view horribly, and makes it impossible to even access the settings again: (Right click & View Image for full size) Yes, I tried to access every corner of the screen using the mouse, but there's just chaos everywhere. Fortunately, I can still log in (pressing "Esc" makes the normal login dialog appear on the left-hand monitor). My question is, how to disable the "magnifier" option outside of the login screen itself? (By editing some config file perhaps?) I don't care about getting the magnifier mode to work properly - just make it go away altogether, please.

Certificate Revocation checking affecting system performance [migrated]

- by Colm Clarke

I have a .NET 3.5 desktop application that had been showing periodic slow downs in functionality whenever the test machine it was on was out of the office. I managed to replicate the error on a machine in the office without an internet connection, but it was only when i used ANTS performance profiler that i got a clearer picture of what was going on. In ANTS I saw a "Waiting for synchronization" taking up to 16 seconds that corresponded to the delay I could see in the application when NHibernate tried to load the System.Data.SqlServerCE.dll assembly. If I tried the action again immediately it would work with no delay but if I left it for 5 minutes then it would be slow to load again the next time I tried it. From my research so far it appears to be because the SqlServerCE dll is signed and so the system is trying to connect to get the certificate revocation lists and timing out. Disabling the "Automatically detect settings" setting in the Internet Options LAN settings makes the problem go away, as does disabling the "Check for publishers certificate revocation". But the admins where this application will be deployed are not going to be happy with the idea of disabling certificate checking on a per machine or per user basis so I really need to get the application level disabling of the CRL check working. There is the well documented bug in .net 2.0 which describes this behaviour, and offers a possible fix with a config file element. <?xml version="1.0" encoding="utf-8"?> <configuration> <runtime> <generatePublisherEvidence enabled="false"/> </runtime> </configuration> This is NOT working for me however even though I am using .net 3.5. The SQLServerCE dll is being loaded dynamically by NHibernate and I wonder if the fact that it's dynamic could somehow be why the setting isn't working, but I don't know how I could check that. Can anyone offer suggestions as to why the config setting might not work? Or is there another way I could disable the check at the application level, perhaps a CAS policy setting that I can use to set an exception for the application when it's installed? Or is there something I can change in the application to up the trust level or something like that? I have also tried using to no advantage ServicePointManager.CheckCertificateRevocationList = false; http://rusanu.com/2009/07/24/fix-slow-application-startup-due-to-code-sign-validation/ I have also tried those registry settings out and unfortunately they didn't help. The dlls that appear to be the cause of the hold up are native SQL Server CE dlls, and looking at the stack traces in ProcMon mscorwks.dll doesn't appear to be involved even though the checks on crypto and cert registry keys are being done under the .NET application. It's definitely still something to do with publisher certificate checking because unticking "Check for publisher revocation certificate" still works but something odd is going on.

Enable Thumbnail Previews for Firefox in Windows 7 Taskbar

- by Asian Angel

Are you tired of waiting for the official activation of Taskbar Thumbnail Previews in Firefox? See how easy it is to enable them now with a simple about:config hack. Note: We have briefly covered this before but present it here in a more detailed format. Before For our example we opened all of the websites in the HTG Network in tabs… When hovering over the Firefox Icon in the Taskbar, you only see the one thumbnail. There are two things in particular to notice here: 1.) The Tab Bar for Firefox is displayed with all four tabs visible in the Thumbnail Preview 2.) The “Taskbar Icon” itself is displaying as singular with no “fanned edge” on the right side. Hack the About:Config Settings To get the Thumbnail Previews working you will need to make a modification in the about:config settings. Type about:config in the Address Bar and press Enter. Unless you have previously disabled the warning you will see this message after pressing Enter. Click on the I promise! Button to finish entering the settings. In the Filter Address Bar either type or copy and paste the following about:config entry: browser.taskbar.previews.enable After you enter that in, you should see the entry listing as shown here. At this point there are two methods that you can choose to alter the entry. The first method is to right click on the entry and select Toggle and the second method is to double click on the entry. Both work equally well…choose the method that you like best. Once the about:config entry has been changed, you will need to restart Firefox for it to take effect. After restarting Firefox on our system the Thumbnail Previews were definitely looking very nice. Notice that the Tab Bar is no longer displayed in the Thumbnail Previews. The Taskbar Icon also had a “fanned edge” indicating that multiple tabs were open. Conclusion If you are tired of waiting for Mozilla to officially activate Taskbar Thumbnail Previews in Firefox, then you can go ahead and start enjoying them now.

No anti-aliasing with Xmonad

- by Leon

I'm looking into Xmonad. One problem I'm having is that most of my applications in Xmonad don't have anti-aliasing. For example gnome-terminal & evolution. I have this in my .Xresources: Xft.dpi: 96 Xft.lcdfilter: lcddefault Xft.antialias: true Xft.autohint: true Xft.hinting: true Xft.hintstyle: hintfull Xft.hintstyle: slight Xft.rgba: rgb And this in my .gtkrc-2.0: gtk-theme-name="Ambiance" gtk-icon-theme-name="ubuntu-mono-dark" gtk-font-name="Sans 10" gtk-cursor-theme-name="DMZ-White" gtk-cursor-theme-size=0 gtk-toolbar-style=GTK_TOOLBAR_BOTH gtk-toolbar-icon-size=GTK_ICON_SIZE_LARGE_TOOLBAR gtk-button-images=1 gtk-menu-images=1 gtk-enable-event-sounds=1 gtk-enable-input-feedback-sounds=1 gtk-xft-antialias=1 gtk-xft-hinting=1 gtk-xft-hintstyle="hintfull" gtk-xft-rgba="rgb" include "/home/leon/.gtkrc-2.0.mine" But I still have no anti-aliasing. When I launch gnome-settings-daemon I do get anti-aliasing. But I don't want to run gnome-settings-daemon. What could be the problem? I'm running Ubuntu 12.04 Desktop.

My laptop is Lenovo T400, which has an internal microphone. My OS is Ubuntu 10.10. My browser is Firefox 11.0. The internal microphone works fine, because I can use it to record my voice using Audaciy. However, in Google talk, I have choose "Internal Audio Analog Stereo" in "Settings - Voice and video chat - Microphone:". But when I click "Verify your settings", it doesn't work. Neither can I speak to others using Google Talk. I wonder why? Thanks and regards!

[GEEK SCHOOL] Network Security 3: Windows Defender and a Malware-Free System

- by Ciprian Rusen

In this second lesson we are going to talk about one of the most confusing security products that are bundled with Windows: Windows Defender. In the past, this product has had a bad reputation and for good reason – it was very limited in its capacity to protect your computer from real-world malware. However, the latest version included in Windows 8.x operating systems is much different than in the past and it provides real protection to its users. The nice thing about Windows Defender in its current incarnation, is that it protects your system from the start, so there are never gaps in coverage. We will start this lesson by explaining what Windows Defender is in Windows 7 and Vista versus what it is in Windows 8, and what product to use if you are using an earlier version. We next will explore how to use Windows Defender, how to improve its default settings, and how to deal with the alerts that it displays. As you will see, Windows Defender will have you using its list of quarantined items a lot more often than other security products. This is why we will explain in detail how to work with it and remove malware for good or restore those items that are only false alarms. Lastly, you will learn how to turn off Windows Defender if you no longer want to use it and you prefer a third-party security product in its place and then how to enable it back, if you have changed your mind about using it. Upon completion, you should have a thorough understanding of your system’s default anti-malware options, or how to protect your system expeditiously. What is Windows Defender? Unfortunately there is no one clear answer to this question because of the confusing way Microsoft has chosen to name its security products. Windows Defender is a different product, depending on the Windows operating system you are using. If you use Windows Vista or Windows 7, then Windows Defender is a security tool that protects your computer from spyware. This but one form of malware made out of tools and applications that monitor your movements on the Internet or the activities you make on your computer. Spyware tends to send the information that is collected to a remote server and it is later used in all kinds of malicious purposes, from displaying advertising you don’t want, to using your personal data, etc. However, there are many other types of malware on the Internet and this version of Windows Defender is not able to protect users from any of them. That’s why, if you are using Windows 7 or earlier, we strongly recommend that you disable Windows Defender and install a more complete security product like Microsoft Security Essentials, or third-party security products from specialized security vendors. If you use Windows 8.x operating systems, then Windows Defender is the same thing as Microsoft Security Essentials: a decent security product that protects your computer in-real time from viruses and spyware. The fact that this product protects your computer also from viruses, not just from spyware, makes a huge difference. If you don’t want to pay for security products, Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) are good alternatives. Windows Defender in Windows 8.x and Microsoft Security Essentials are the same product, only their name is different. In this lesson, we will use the Windows Defender version from Windows 8.x but our instructions apply also to Microsoft Security Essentials (MSE) in Windows 7 and Windows Vista. If you want to download Microsoft Security Essentials and try it out, we recommend you to use this page: Download Microsoft Security Essentials. There you will find both 32-bit and 64-bit editions of this product as well versions in multiple languages. How to Use and Configure Windows Defender Using Windows Defender (MSE) is very easy to use. To start, search for “defender” on the Windows 8.x Start screen and click or tap the “Windows Defender” search result. In Windows 7, search for “security” in the Start Menu search box and click “Microsoft Security Essentials”. Windows Defender has four tabs which give you access to the following tools and options: Home – here you can view the security status of your system. If everything is alright, then it will be colored in green. If there are some warnings to consider, then it will be colored in yellow, and if there are threats that must be dealt with, everything will be colored in red. On the right side of the “Home” tab you will find options for scanning your computer for viruses and spyware. On the bottom of the tab you will find information about when the last scan was performed and what type of scan it was. Update – here you will find information on whether this product is up-to-date. You will learn when it was last updated and the versions of the definitions it is using. You can also trigger a manual update. History – here you can access quarantined items, see which items you’ve allowed to run on your PC even if they were identified as malware by Windows Defender, and view a complete list with all the malicious items Windows Defender has detected on your PC. In order to access all these lists and work with them, you need to be signed in as an administrator. Settings – this is the tab where you can turn on the real-time protection service, exclude files, file types, processes, and locations from its scans as well as access a couple of more advanced settings. The only difference between Windows Defender in Windows 8.x and Microsoft Security Essentials (in Windows 7 or earlier) is that, in the “Settings” tab, Microsoft Security Essentials allows you to set when to run scheduled scans while Windows Defender lacks this option.
