• Help trying to get two-finger scrolling to work on Asus UL80VT

  - by Dan2k3k4

  Multi-touch works fine on Windows 7 with: two-fingers scroll vertical and horizontally, two-finger tap for middle click, and three-finger tap for right click. However with Ubuntu, I've never been able to get multi-touch to "save" and work, I was able to get it to work a few times but after restarting - it would just reset back. I have the settings for two-finger scrolling on: Mouse and Touchpad Touchpad Two-finger scrolling (selected) Enable horizontal scrolling (ticked) The cursor stops moving when I try to scroll with two fingers, but it doesn't actually scroll the page. When I perform xinput list, I get: Virtual core pointer id=2 [master pointer (3)] ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ETPS/2 Elantech ETF0401 id=13 [slave pointer (2)] I've tried to install some 'synaptics-dkms' bug-fix (from a few years back) but that didn't work, so I removed that. I've tried installing 'uTouch' but that didn't seem to do anything so removed it. Here's what I have installed now: dpkg --get-selections installed-software grep 'touch\|mouse\|track\|synapt' installed-software libsoundtouch0 --- install libutouch-evemu1 --- install libutouch-frame1 --- install libutouch-geis1 --- install libutouch-grail1 --- install printer-driver-ptouch --- install ptouch-driver --- install xserver-xorg-input-multitouch --- install xserver-xorg-input-mouse --- install xserver-xorg-input-vmmouse --- install libnetfilter-conntrack3 --- install libxatracker1 --- install xserver-xorg-input-synaptics --- install So, I'll start again, what should I do now to get two-finger scrolling to work and ensure it works after restarting? Also doing: synclient TapButton1=1 TapButton2=2 TapButton3=3 ...works but doesn't save after restarting. However doing: synclient VertTwoFingerScroll=1 HorizTwoFingerScroll=1 Does NOT work to fix the two-finger scrolling.

Temporary Fix (works until I restart) Doing the following commands: modprobe -r psmouse modprobe psmouse proto=imps Works but now xinput list shows up as: Virtual core pointer id=2 [master pointer (3)] ?

Solution (not ideal for most people) So, I ended up reinstalling a fresh 12.04 after indirectly playing around with burg and plymouth then removing plymouth which removed 50+ packages (I saw the warnings but was way too tired and assumed I could just 'reinstall' them all after (except that didn't work).

• Algorithm for querying linearly through a non-linear list of questions

  - by JoshLeaves

  For a multiplayers trivia game, I need to supply my users with a new quizz in a desired subject (Science, Maths, Litt. and such) at the start of every game. I've generated about 5K quizzes for each subject and filled my database with them. So my 'Quizzes' database looks like this: |ID |Subject |Question +-----+------------+---------------------------------- | 23 |Science | What's water? | 42 |Maths | What's 2+2? | 99 |Litt. | Who wrote "Pride and Prejudice"? | 123 |Litt. | Who wrote "On The Road"? | 146 |Maths | What's 2*2? | 599 |Science | You know what's cool? |1042 |Maths | What's the Fibonacci Sequence? |1056 |Maths | What's 42? And so on... (Much more detailed/complex but I'll keep the exemple simple) As you can see, due to technical constraints (MongoDB), my IDs are not linear but I can use them as an increasing suite. So far, my algorithm to ensure two users get a new quizz when they play together is the following: // Take the last played quizzes by P1 and P2 var q_one = player_one.getLastPlayedQuizz('Maths'); var q_two = player_two.getLastPlayedQuizz('Maths'); // If both of them never played in the subject, return first quizz in the list if ((q_one == NULL) && (q_two == NULL)) return QuizzDB.findOne({subject: 'Maths'}); // If one of them never played, play the next quizz for the other player // This quizz is found by asking for the first quizz in the desired subject where // the ID is greater than the last played quizz's ID (if the last played quizz ID // is 42, this will return 146 following the above example database) if (q_one == NULL) return QuizzDB.findOne({subject: 'Maths', ID > q_two}); if (q_two == NULL) return QuizzDB.findOne({subject: 'Maths', ID > q_one}); // And if both of them have a lastPlayedQuizz, we return the next quizz for the // player whose lastPlayedQuizz got the higher ID if (q_one > q_two) return QuizzDB.findOne({subject: 'Maths', ID > q_one}); else return QuizzDB.findOne({subject: 'Maths', ID > q_two}); Now here comes the real problem: Once I get to the end of my database (let's say, P1's last played quizz in 'Maths' is 1056, P2's is 146 and P3 is 1042), following my algorithm, P1's ID is the highest so I ask for the next question in 'Maths' where ID is superior to 1056. There is nothing, so I roll back to the beginning of my quizz list (with a random skipper to avoid having the first question always show up). P1 and P2's last played will then be 42 and they will start fresh from the beginning of the list. However, if P1 (42) plays against P3 (1042), the resulting ID will be 1056...which P1 already played two games ago. Basically, players who just "rolled back" to the beginning of the list will be brought back to the end of the list by players who still haven't rolled back. The rollback WILL happen in the end, but it'll take time and there'll be a "bottleneck" at the beginning and at the end. Thus my question: What would be the best algorith to avoid this bottleneck and ensure players don't get stuck endlessly on the same quizzes? Also bear in mind that I've got some technical constraints: I can't get a random question in a subject (ie: no "QuizzDB.findOne({subject: 'Maths'}).skip(random());"). It's cool to skip on one to twenty records, but the MongoDB documentation warns against skipping too many documents. I would like to avoid building an array of every quizz played by each player and find the next non-played in the database with a $nin. Thanks for your help

• WebGrid Helper and Complex Types

  - by imran_ku07

      Introduction:           WebGrid helper makes it very easy to show tabular data. It was originally designed for ASP.NET Web Pages(WebMatrix) to display, edit, page and sort tabular data but you can also use this helper in ASP.NET Web Forms and ASP.NET MVC. When using this helper, sometimes you may run into a problem if you use complex types in this helper. In this article, I will show you how you can use complex types in WebGrid helper.       Description:             Let's say you need to show the employee data and you have the following classes,   public class Employee { public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } } public class Address { public string City { get; set; } }               The Employee class contain a Name, an Address and list of ContactNumbers. You may think that you can easily show City in WebGrid using Address.City, but no. The WebGrid helper will throw an exception at runtime if any Address property is null in the Employee list. Also, you cannot directly show ContactNumbers property. The easiest way to show these properties is to add some additional properties,   public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } }               Now you can easily use these properties in WebGrid. Here is the complete code of this example,  @functions{ public class Employee { public Employee(){ ContactNumbers = new List<string>(); } public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } } } public class Address { public string City { get; set; } } } @{ var myClasses = new List<Employee>{ new Employee { Name="A" , Address = new Address{ City="AA" }, ContactNumbers = new List<string>{"021-216452","9231425651"}}, new Employee { Name="C" , Address = new Address{ City="CC" }}, new Employee { Name="D" , ContactNumbers = new List<string>{"045-14512125","21531212121"}} }; var grid = new WebGrid(source: myClasses); } @grid.GetHtml(columns: grid.Columns( grid.Column("NotNullableAddress.City", header: "City"), grid.Column("Name"), grid.Column("Contacts")))                    Summary:           You can use WebGrid helper to show tabular data in ASP.NET MVC, ASP.NET Web Forms and  ASP.NET Web Pages. Using this helper, you can also show complex types in the grid. In this article, I showed you how you use complex types with WebGrid helper. Hopefully you will enjoy this article too.

• Templated Razor Delegates – Phil Haack

  - by nmarun

  This post is largely based off of Phil Haack’s article titled Templated Razor Delegates. I strongly recommend reading this article first. Here’s a sample code for the same, so you can have a look at. I also have a custom type being rendered as a table. 1: // my custom type 2: public class Device 3: { 4: public int Id { get; set; } 5: public string Name { get; set; } 6: public DateTime MfgDate { get; set; } 7: } Now I can write an extension method just for this type. 1: public static class RazorExtensions 2: { 3: public static HelperResult List(this IList<Models.Device> devices, Func<Models.Device, HelperResult> template) 4: { 5: return new HelperResult(writer => 6: { 7: foreach (var device in devices) 8: { 9: template(device).WriteTo(writer); 10: } 11: }); 12: } 13: // ... 14: } Modified my view to make it a strongly typed one and included html to render my custom type collection in a table. 1: @using TemplatedRazorDelegates 2: @model System.Collections.Generic.IList<TemplatedRazorDelegates.Models.Device> 3:  4: @{ 5: ViewBag.Title = "Home Page"; 6: } 7:  8: <h2>@ViewBag.Message</h2> 9:  10: @{ 11: var items = new[] { "one", "two", "three" }; 12: IList<int> ints = new List<int> { 1, 2, 3 }; 13: } 14:  15: <ul> 16: @items.List(@<li>@item</li>) 17: </ul> 18: <ul> 19: @ints.List(@<li>@item</li>) 20: </ul> 21:  22: <table> 23: <tr><th>Id</th><th>Name</th><th>Mfg Date</th></tr> 24: @Model.List(@<tr><td>@item.Id</td><td>@item.Name</td><td>@item.MfgDate.ToShortDateString()</td></tr>) 25: </table> We get intellisense as well! Just added some items in the action method of the controller: 1: public ActionResult Index() 2: { 3: ViewBag.Message = "Welcome to ASP.NET MVC!"; 4: IList<Device> devices = new List<Device> 5: { 6: new Device {Id = 1, Name = "abc", MfgDate = new DateTime(2001, 10, 19)}, 7: new Device {Id = 2, Name = "def", MfgDate = new DateTime(2011, 1, 1)}, 8: new Device {Id = 3, Name = "ghi", MfgDate = new DateTime(2003, 3, 15)}, 9: new Device {Id = 4, Name = "jkl", MfgDate = new DateTime(2007, 6, 6)} 10: }; 11: return View(devices); 12: } Running this I get the output as: Absolutely brilliant! Thanks to both Phil Haack and to David Fowler for bringing this out to us. Download the code for this from here. Verdict: RazorViewEngine.Points += 1;

• Binding a select in a client template

  - by Bertrand Le Roy

  I recently got a question on one of my client template posts asking me how to bind a select tag’s value to data in client templates. I was surprised not to find anything on the web addressing the problem, so I thought I’d write a short post about it. It really is very simple once you know where to look. You just need to bind the value property of the select tag, like this: <select sys:value="{binding color}"> If you do it from markup like here, you just need to use the sys: prefix. It just works. Here’s the full source code for my sample page: <!DOCTYPE html> <html> <head> <title>Binding a select tag</title> <script src=http://ajax.microsoft.com/ajax/beta/0911/Start.js type="text/javascript"></script> <script type="text/javascript"> Sys.require(Sys.scripts.Templates, function() { var colors = [ "red", "green", "blue", "cyan", "purple", "yellow" ]; var things = [ { what: "object", color: "blue" }, { what: "entity", color: "purple" }, { what: "thing", color: "green" } ]; Sys.create.dataView("#thingList", { data: things, itemRendered: function(view, ctx) { Sys.create.dataView( Sys.get("#colorSelect", ctx), { data: colors }); } }); }); </script> <style type="text/css"> .sys-template {display: none;} </style> </head> <body xmlns:sys="javascript:Sys"> <div> <ul id="thingList" class="sys-template"> <li> <span sys:id="thingName" sys:style-color="{binding color}" >{{what}}</span> <select sys:id="colorSelect" sys:value="{binding color}" class="sys-template"> <option sys:value="{{$dataItem}}" sys:style-background-color="{{$dataItem}}" >{{$dataItem}}</option> </select> </li> </ul> </div> </body> </html> This produces the following page: Each of the items sees its color change as you select a different color in the drop-down. Other details worth noting in this page are the use of the script loader to get the framework from the CDN, and the sys:style-background-color syntax to bind the background color style property from markup. Of course, I’ve used a fair amount of custom ASP.NET Ajax markup in here, but everything could be done imperatively and with completely clean markup from the itemRendered event using Sys.bind.

• Two small issues with Windows Phone 7 ApplicationBar buttons (and workaround)

  - by Laurent Bugnion

  When you work with the ApplicationBar in Windows Phone 7, you notice very fast that it is not quite a component like the others. For example, the ApplicationBarIconButton element is not a dependency object, which causes issues because it is not possible to add attached properties to it. Here are two other issues I stumbled upon, and what workaround I used to make it work anyway. Finding a button by name returns null Since the ApplicationBar is not in the tree of the Silverlight page, finding an element by name fails. For example consider the following code: <phoneNavigation:PhoneApplicationPage.ApplicationBar> <shell:ApplicationBar> <shell:ApplicationBar.Buttons> <shell:ApplicationBarIconButton IconUri="/Resources/edit.png" Click="EditButtonClick" x:Name="EditButton"/> <shell:ApplicationBarIconButton IconUri="/Resources/cancel.png" Click="CancelButtonClick" x:Name="CancelButton"/> </shell:ApplicationBar.Buttons> </shell:ApplicationBar> </phoneNavigation:PhoneApplicationPage.ApplicationBar> with private void EditButtonClick( object sender, EventArgs e) { CancelButton.IsEnabled = false; // Fails, CancelButton is always null } The CancelButton, even though it is named through an x:Name attribute, and even though it appears in Intellisense in the code behind, is null when it is needed. To solve the issue, I use the following code: public enum IconButton { Edit = 0, Cancel = 1 } public ApplicationBarIconButton GetButton( IconButton which) { return ApplicationBar.Buttons[(int) which] as ApplicationBarIconButton; } private void EditButtonClick( object sender, EventArgs e) { GetButton(IconButton.Cancel).IsEnabled = false; } Updating a Binding when the icon button is clicked In Silverlight, a Binding on a TextBox’s Text property can only be updated in two circumstances: When the TextBox loses the focus. Explicitly by placing a call in code. In WPF, there is a third option, updating the Binding every time that the Text property changes (i.e. every time that the user types a character). Unfortunately this option is not available in Silverlight). To select option 1, 2 (and in WPF, 3), you use the Mode property of the Binding class. The issue here is that pressing a button on the ApplicationBar does not remove the focus from the TextBox where the user is currently typing. If the button is a Save button, this is super annoying: The Binding does not get updated on the data object, the object is saved anyway with the old state, and noone understands what just happened. In order to solve this, you can make sure that the Binding is updated explicitly when the button is pressed, with the following code: private void SaveButtonClick(object sender, EventArgs e) { // Force update binding first var binding = MessageTextBox.GetBindingExpression( TextBox.TextProperty); binding.UpdateSource(); // Property was updated for sure, now we can save var vm = DataContext as MainViewModel; vm.Save(); } Obviously this is less maintainable than the usual way to do things in Silverlight. So be careful when using the ApplicationBar and remember that it is not a Silverlight element like the others!! Happy coding!

• Improving WIF&rsquo;s Claims-based Authorization - Part 1

  - by Your DisplayName here!

  As mentioned in my last post, I made several additions to WIF’s built-in authorization infrastructure to make it more flexible and easy to use. The foundation for all this work is that you have to be able to directly call the registered ClaimsAuthorizationManager. The following snippet is the universal way to get to the WIF configuration that is currently in effect: public static ServiceConfiguration ServiceConfiguration {     get     {         if (OperationContext.Current == null)         {             // no WCF             return FederatedAuthentication.ServiceConfiguration;         }         // search message property         if (OperationContext.Current.IncomingMessageProperties. ContainsKey("ServiceConfiguration"))         {             var configuration = OperationContext.Current. IncomingMessageProperties["ServiceConfiguration"] as ServiceConfiguration;             if (configuration != null)             {                 return configuration;             }         }         // return configuration from configuration file         return new ServiceConfiguration();     } }   From here you can grab ServiceConfiguration.ClaimsAuthoriationManager which give you direct access to the CheckAccess method (and thus control over claim types and values). I then created the following wrapper methods: public static bool CheckAccess(string resource, string action) {     return CheckAccess(resource, action, Thread.CurrentPrincipal as IClaimsPrincipal); } public static bool CheckAccess(string resource, string action, IClaimsPrincipal principal) {     var context = new AuthorizationContext(principal, resource, action);     return AuthorizationManager.CheckAccess(context); } public static bool CheckAccess(Collection<Claim> actions, Collection<Claim> resources) {     return CheckAccess(new AuthorizationContext(         Thread.CurrentPrincipal.AsClaimsPrincipal(), resources, actions)); } public static bool CheckAccess(AuthorizationContext context) {     return AuthorizationManager.CheckAccess(context); } I also created the same set of methods but called DemandAccess. They internally use CheckAccess and will throw a SecurityException when false is returned. All the code is part of Thinktecture.IdentityModel on Codeplex – or via NuGet (Install-Package Thinktecture.IdentityModel).

• MVC Portable Areas &ndash; Deploying Static Files

  - by Steve Michelotti

  This is the second post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources As I’ve been digging more into portable areas, one of the things I’ve liked best is the deployment story which enables my *.aspx, *.ascx pages to be compiled into the assembly as embedded resources rather than having to maintain all those files separately. In traditional web forms, that was always the thing to prevented developers from utilizing *.ascx user controls across projects (see this post for using portable areas in web forms).  However, though the aspx pages are embedded, the supporting static files (e.g., images, css, javascript) are *not*. Most of the demos available online today tend to brush over this issue and focus solely on the aspx side of things. But to create truly robust portable areas, it’s important to have a good story for these supporting files as well.  I’ve been working with two different approaches so far (of course I’d really like to hear if other people are using alternatives). Scenario For the approaches below, the scenario really isn’t that important. It could be something as trivial as this partial view: 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> 2: <img src="<%: Url.Content("~/images/arrow.gif") %>" /> Hello World! The point is that there needs to be careful consideration for *any* scenario that links to an external file such as an image, *.css, *.js, etc. In the example shown above, it uses the Url.Content() method to convert to a relative path. But this method won’t necessary work depending on how you deploy your portable area. One approach to address this issue is to build your portable area project with MSDeploy/WebDeploy so that it is packaged properly before incorporating into the host application. All of the *.cs files are removed and the project is ready for xcopy deployment – however, I do *not* need the “Views” folder since all of the mark up has been compiled into the assembly as embedded resources. Now in the host application we create a folder called “Modules” and deploy any portable areas as sub-folders under that: At this point we can add a simple assembly reference to the Widget1.dll sitting in the Modules\Widget1\bin folder. I can now render the portable image in my view like any other portable area. However, the problem with that is that the view results in this:   It couldn’t find arrow.gif because it looked for /images/arrow.gif and it was *actually* located at /images/Modules/Widget1/images/arrow.gif. One solution is to make the physical location of the portable configurable from the perspective of the host like this: 1: <appSettings> 2: <add key="Widget1" value="Modules\Widget1"/> 3: </appSettings> Using the <appSettings> section is a little cheesy but it could be better formalized into its own section. In fact, if were you willing to rely on conventions (e.g., “Modules\{areaName}”) then then config could be eliminated completely. With this config in place, we could create our own Html helper method called Url.AreaContent() that “wraps” the OOTB Url.Content() method while simply pre-pending the area location path: 1: public static string AreaContent(this UrlHelper urlHelper, string contentPath) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: var areaPath = (string)ConfigurationManager.AppSettings[areaName]; 5:   6: return urlHelper.Content("~/" + areaPath + "/" + contentPath); With these two items in place, we just change our Url.Content() call to Url.AreaContent() like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! and the arrow.gif now renders correctly:     Since we’re just using our own Url.AreaContent() rather than the built-in Url.Content(), this solution works for images, *.css, *.js, or any externally referenced files.  Additionally, any images referenced inside a css file will work provided it’s a relative reference and not an absolute reference. An alternative to this approach is to build the static file into the assembly as embedded resources themselves. I’ll explore this in another post (linked at the top).

• I can't shut down nor reboot without console

  - by jgomo3

  After update from 11.04 to 11.10 an wired conduct appears in my machine: Shutdown GUI methods (including reboot) cause only a log off, and in the login screen, shutdown nor reboot options do anything (if you wonder, reboot appears in the shutdown dialog). The only way i can reboot or shutdown is trough console sudo shutdown -h now or sudo reboot. This is OK for me, but not for the rest of the users. How to fix this?

• Is inconsistent formatting a sign of a sloppy programmer?

  - by dreza

  I understand that everyone has their own style of programming and that you should be able to read other people's styles and accept it for what it is. However, would one be considered a sloppy programmer if one's style of coding was inconsistent across whatever standard they were working against? Some example of inconsistencies might be: Sometimes naming private variables with _ and sometimes not Sometimes having varying indentations within code blocks Not aligning braces up i.e. same column if using start using new line style Spacing not always consistent around operators i.e. p=p+1, p+=1 vs other times p =p+1 or p = p + 1 etc Is this even something that as a programmer I should be concerned with addressing? Or is it such a minor nit picking thing that at the end of the day I should just not worry about it and worry about what the end user sees and whether the code works rather than how it looks while working? Is it sloppy programming or just over obsessive nit picking? EDIT: After some excellent comments I realized I may have left out some information in my question. This question came about after reviewing another colleagues code check-in and noticing some of these things and then realizing that I've seen these kind of in-consistencies in previous check-ins. It then got me thinking about my code and whether I do the same things and noticed that I typically don't etc I'm not suggesting his technique is either bad or good in this question or whether his way of doing things is right or wrong. EDIT: To answer some queries to some more good feed back. The specific instance this review occurred in was using Visual Studio 2010 and programming in c# so I don't think the editor would cause any issues. In fact it should only help I would hope. Sorry if I left that piece of info out and it effects any current answers. I was trying to be a bit more generic in understanding if this would be considered sloppy etc. And to add an even more specific example of a code piece I saw during reading of the check-in: foreach(var block in Blocks) { // .. some other code in here foreach(var movement in movements) { movement.Moved.Zero(); } // the un-formatted brace } Such a minor thing I know, but many small things add up(???), and I did have to double glance at the code at the time to see where everything lined up I guess. Please note this code was formatted appropriately before this check-in. EDIT: After reading some great answers and varying thoughts, the summary I've taken from this was. It's not necessarily a sign of a sloppy programmer however as programmers we have a duty (to ourselves and other programmers) to make the code as readable as possible to assist in further ongoing development. However it can hint at inadequacies which is something that is only possible to review on a case by case (person by person) basis. There are many reasons why this might occur. They should be taken in context and worked through with the person/people involved if reasonable. We have a duty to try and help all programmers become better programmers! In the good old days when development was done using good old notepad (or other simple text editing tool) this occurred much more frequently. However we have the assistance of modern IDE's now so although we shouldn't necessarily become OTT about this, it should still probably be addressed to some degree. We as programmers vary in our standards, styles and approaches to solutions. However it seems that in general we all take PRIDE in our work and as a trait it is something that can stand programmers apart. Making something to the best of our abilities both internal (code) and external (end user result) goes along way to giving us that big fat pat on the back that we may not go looking for but swells our heart with pride. And finally to quote CrazyEddie from his post below. Don't sweat the small stuff

• forEach and Facelets - a bugfarm just waiting for harvest

  - by Duncan Mills

  An issue that I've encountered before and saw again today seems worthy of a little write-up. It's all to do with a subtle yet highly important difference in behaviour between JSF 2 running with JSP and running on Facelets (.jsf pages). The incident I saw today can be seen as a report on the ADF EMG bugzilla (Issue 53) and in a blog posting by Ulrich Gerkmann-Bartels who reported the issue to the EMG. Ulrich's issue nicely shows how tricky this particular gochya can be. On the surface, the problem is squarely the fault of MDS but underneath MDS is, in fact, innocent. To summarize the problem in a simpler testcase than Ulrich's example, here's a simple fragment of code: <af:forEach var="item" items="#{itemList.items}"> <af:commandLink id="cl1" text="#{item.label}" action="#{item.doAction}"  partialSubmit="true"/> </af:forEach> Looks innocent enough right? We see a bunch of links printed out, great. The issue here though is the id attribute. Logically you can kind of see the problem. The forEach loop is creating (presumably) multiple instances of the commandLink, but only one id is specified - cl1. We know that IDs have to be unique within a JSF component tree, so that must be a bad thing?  The problem is that JSF under JSP implements some hacks when the component tree is generated to transparently fix this problem for you. Behind the scenes it ensures that each instance really does have a unique id. Really nice of it to do so, thank you very much. However, (you could see this coming), the same is not true when running with Facelets  (this is under 11.1.2.n)  in that case, what you put for the id is what you get, and JSF does not mess around in the background for you. So you end up with a component tree that contains duplicate ids which are only created at runtime.  So subtle chaos can ensue.  The symptoms are wide and varied, from something pretty obscure such as the combination Ulrich uncovered, to something as frustrating as your ActionListener just not being triggered. And yes I've wasted hours on just such an issue.  The Solution  Once you're aware of this one it's really simple to fix it, there are two options: Remove the id attribute on components that will cause some kind of submission within the forEach loop altogether and let JSF do the right thing in generating them. Then you'll be assured of uniqueness. Use the var attribute of the loop to generate a unique id for each child instance.  for example in the above case: <af:commandLink id="cl1_#{item.index}" ... />.  So one to watch out for in your upgrades to JSF 2 and one perhaps, for your coding standards today to prepare you for. For completeness, here's the reference to the underlying JSF issue that's at the heart of this: JAVASERVERFACES-1527

• How to create Checkboxes that act like Radio buttons with Jquery

  - by hmloo

  I have a post here to show code examples for check/uncheck all checkbox with Jquery. This time I will implement another request that the user should only be able to check at most one of the checkboxes, it's behave like radio buttons. There are 2 cases. Case 1 shows function that has little difference with radio button. It allows the user to deselect checkbox. Case 2 is same as radio button. Case 1 <head id="Head1" runat="server"> <title></title> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <style type="text/css"> .cbRowItem {display:block;} </style> <script type="text/javascript"> $(document).ready(function() { var $chk = $('input:checkbox .cbRowItem'); $chk.click(function() { $chk.not(this).removeAttr('checked'); }); }); </script> </head> <body> <form id="form1" runat="server"> <div style="display:block;"> <asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem" Text = "CheckBox 1"/> <asp:CheckBox id="CheckBox2" runat="server" class="cbRowItem" Text = "CheckBox 2"/> <asp:CheckBox id="CheckBox3" runat="server" class="cbRowItem" Text = "CheckBox 3"/> <asp:CheckBox id="CheckBox4" runat="server" class="cbRowItem" Text = "CheckBox 4"/> </div> </form> </body> </html> Case 2 <head id="Head1" runat="server"> <title></title> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <style type="text/css"> .cbRowItem {display:block;} </style> <script type="text/javascript"> $(document).ready(function() { var $chk = $('input:checkbox .cbRowItem'); $chk.click(function() { $chk.removeAttr('checked'); $(this).attr('checked', 'checked'); }); }); </script> </head> <body> <form id="form1" runat="server"> <div style="display:block;"> <asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem" Text = "CheckBox 1"/> <asp:CheckBox id="CheckBox2" runat="server" class="cbRowItem" Text = "CheckBox 2"/> <asp:CheckBox id="CheckBox3" runat="server" class="cbRowItem" Text = "CheckBox 3"/> <asp:CheckBox id="CheckBox4" runat="server" class="cbRowItem" Text = "CheckBox 4"/> </div> </form> </body> </html>

  I know this has been asked several times, but each issue and resolution seems different. I've tried almost everything I could think of, but I can't fix this. I have a VM (VMware I think) running 12.04.03 LTS which has stuck dependencies. The VM is on a rented host, running a live system so I don't want to break it (further). uname -a Linux support 3.5.0-36-generic #57~precise1-Ubuntu SMP Thu Jun 20 18:21:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Some more: sudo apt-get update [sudo] password for tracker: Reading package lists...

Y dpkg: dependency problems prevent configuration of initramfs-tools: initramfs-tools depends on initramfs-tools-bin (<< 0.99ubuntu13.1.1~); however: Version of initramfs-tools-bin on system is 0.99ubuntu13.3. dpkg: error processing initramfs-tools (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure. dpkg: dependency problems prevent configuration of apparmor: apparmor depends on initramfs-tools; however: Package initramfs-tools is not configured yet. dpkg: error processing apparmor (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure. Errors were encountered while processing: initramfs-tools apparmor E: Sub-process /usr/bin/dpkg returned an error code (1) If I look at the policy behind initramfs-tools / bin I get: apt-cache policy initramfs-tools initramfs-tools: Installed: 0.99ubuntu13.1 Candidate: 0.99ubuntu13.3 Version table: 0.99ubuntu13.3 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages *** 0.99ubuntu13.1 0 100 /var/lib/dpkg/status 0.99ubuntu13 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages apt-cache policy initramfs-tools-bin initramfs-tools-bin: Installed: 0.99ubuntu13.3 Candidate: 0.99ubuntu13.3 Version table: *** 0.99ubuntu13.3 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status 0.99ubuntu13 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages So the issue seems to be I have 0.99ubuntu13.3 for initramfs-tools-bin yet 0.99ubuntu13.1 for initramfs-tools, and can't upgrade to 0.99ubuntu13.3. I've performed apt-get clean/autoclean/install -f/upgrade -f many times but they won't resolve. I can think of only 2 other 'solutions': Edit the dpkg dependency list to trick it into doing the installation with a broken dependency. This seems very dodgy and it would be a last resort Downgrade both initramfs-tools and initramfs-tools-bin to 0.99ubuntu13 from the precise/main sources and hope that would get them in step. However I'm not sure if this will be possible, or whether it would introduce more issues. I'm not sure how this situation arise in the first place. /boot was 96% full; it's now 56% full (it's tiny - 64MB ... this is what I got from the hosting company). Can anyone offer advice please?

• An Unusual UpdatePanel

  - by João Angelo

  The code you are about to see was mostly to prove a point, to myself, and probably has limited applicability. Nonetheless, in the remote possibility this is useful to someone here it goes… So this is a control that acts like a normal UpdatePanel where all child controls are registered as postback triggers except for a single control specified by the TriggerControlID property. You could basically achieve the same thing by registering all controls as postback triggers in the regular UpdatePanel. However with this, that process is performed automatically. Finally, here is the code: public sealed class SingleAsyncTriggerUpdatePanel : WebControl, INamingContainer { public string TriggerControlID { get; set; } [TemplateInstance(TemplateInstance.Single)] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate ContentTemplate { get; set; } public override ControlCollection Controls { get { this.EnsureChildControls(); return base.Controls; } } protected override void CreateChildControls() { if (string.IsNullOrWhiteSpace(this.TriggerControlID)) throw new InvalidOperationException( "The TriggerControlId property must be set."); this.Controls.Clear(); var updatePanel = new UpdatePanel() { ID = string.Concat(this.ID, "InnerUpdatePanel"), ChildrenAsTriggers = false, UpdateMode = UpdatePanelUpdateMode.Conditional, ContentTemplate = this.ContentTemplate }; updatePanel.Triggers.Add(new SingleControlAsyncUpdatePanelTrigger { ControlID = this.TriggerControlID }); this.Controls.Add(updatePanel); } } internal sealed class SingleControlAsyncUpdatePanelTrigger : UpdatePanelControlTrigger { private Control target; private ScriptManager scriptManager; public Control Target { get { if (this.target == null) { this.target = this.FindTargetControl(true); } return this.target; } } public ScriptManager ScriptManager { get { if (this.scriptManager == null) { var page = base.Owner.Page; if (page != null) { this.scriptManager = ScriptManager.GetCurrent(page); } } return this.scriptManager; } } protected override bool HasTriggered() { string asyncPostBackSourceElementID = this.ScriptManager.AsyncPostBackSourceElementID; if (asyncPostBackSourceElementID == this.Target.UniqueID) return true; return asyncPostBackSourceElementID.StartsWith( string.Concat(this.target.UniqueID, "$"), StringComparison.Ordinal); } protected override void Initialize() { base.Initialize(); foreach (Control control in FlattenControlHierarchy(this.Owner.Controls)) { if (control == this.Target) continue; bool isApplicableControl = false; isApplicableControl |= control is INamingContainer; isApplicableControl |= control is IPostBackDataHandler; isApplicableControl |= control is IPostBackEventHandler; if (isApplicableControl) { this.ScriptManager.RegisterPostBackControl(control); } } } private static IEnumerable<Control> FlattenControlHierarchy( ControlCollection collection) { foreach (Control control in collection) { yield return control; if (control.Controls.Count > 0) { foreach (Control child in FlattenControlHierarchy(control.Controls)) { yield return child; } } } } } You can use it like this, meaning that only the B2 button will trigger an async postback: <cc:SingleAsyncTriggerUpdatePanel ID="Test" runat="server" TriggerControlID="B2"> <ContentTemplate> <asp:Button ID="B1" Text="B1" runat="server" OnClick="Button_Click" /> <asp:Button ID="B2" Text="B2" runat="server" OnClick="Button_Click" /> <asp:Button ID="B3" Text="B3" runat="server" OnClick="Button_Click" /> <asp:Label ID="LInner" Text="LInner" runat="server" /> </ContentTemplate> </cc:SingleAsyncTriggerUpdatePanel>

• Bug in Delphi XE RegularExpressions Unit

  - by Jan Goyvaerts

  Using the new RegularExpressions unit in Delphi XE, you can iterate over all the matches that a regex finds in a string like this: procedure TForm1.Button1Click(Sender: TObject); var RegEx: TRegEx; Match: TMatch; begin RegEx := TRegex.Create('\w+'); Match := RegEx.Match('One two three four'); while Match.Success do begin Memo1.Lines.Add(Match.Value); Match := Match.NextMatch; end end; Or you could save yourself two lines of code by using the static TRegEx.Match call: procedure TForm1.Button2Click(Sender: TObject); var Match: TMatch; begin Match := TRegEx.Match('One two three four', '\w+'); while Match.Success do begin Memo1.Lines.Add(Match.Value); Match := Match.NextMatch; end end; Unfortunately, due to a bug in the RegularExpressions unit, the static call doesn’t work. Depending on your exact code, you may get fewer matches or blank matches than you should, or your application may crash with an access violation. The RegularExpressions unit defines TRegEx and TMatch as records. That way you don’t have to explicitly create and destroy them. Internally, TRegEx uses TPerlRegEx to do the heavy lifting. TPerlRegEx is a class that needs to be created and destroyed like any other class. If you look at the TRegEx source code, you’ll notice that it uses an interface to destroy the TPerlRegEx instance when TRegEx goes out of scope. Interfaces are reference counted in Delphi, making them usable for automatic memory management. The bug is that TMatch and TGroupCollection also need the TPerlRegEx instance to do their work. TRegEx passes its TPerlRegEx instance to TMatch and TGroupCollection, but it does not pass the instance of the interface that is responsible for destroying TPerlRegEx. This is not a problem in our first code sample. TRegEx stays in scope until we’re done with TMatch. The interface is destroyed when Button1Click exits. In the second code sample, the static TRegEx.Match call creates a local variable of type TRegEx. This local variable goes out of scope when TRegEx.Match returns. Thus the reference count on the interface reaches zero and TPerlRegEx is destroyed when TRegEx.Match returns. When we call MatchAgain the TMatch record tries to use a TPerlRegEx instance that has already been destroyed. To fix this bug, delete or rename the two RegularExpressions.dcu files and copy RegularExpressions.pas into your source code folder. Make these changes to both the TMatch and TGroupCollection records in this unit: Declare FNotifier: IInterface; in the private section. Add the parameter ANotifier: IInterface; to the Create constructor. Assign FNotifier := ANotifier; in the constructor’s implementation. You also need to add the ANotifier: IInterface; parameter to the TMatchCollection.Create constructor. Now try to compile some code that uses the RegularExpressions unit. The compiler will flag all calls to TMatch.Create, TGroupCollection.Create and TMatchCollection.Create. Fix them by adding the ANotifier or FNotifier parameter, depending on whether ARegEx or FRegEx is being passed. With these fixes, the TPerlRegEx instance won’t be destroyed until the last TRegEx, TMatch, or TGroupCollection that uses it goes out of scope or is used with a different regular expression.

• CacheAdapter 2.4 – Bug fixes and minor functional update

  - by Glav

  Note: If you are unfamiliar with the CacheAdapter library and what it does, you can read all about its awesome ability to utilise memory, Asp.Net Web, Windows Azure AppFabric and memcached caching implementations via a single unified, simple to use API from here and here.. The CacheAdapter library is receiving an update to version 2.4 and is currently available on Nuget here. Update: The CacheAdapter has actualy just had a minor revision to 2.4.1. This significantly increases the performance and reliability in memcached scenario under more extreme loads. General to moderate usage wont see any noticeable difference though. Bugs This latest version fixes a big that is only present in the memcached implementation and is only seen in rare, intermittent times (making i particularly hard to find). The bug is where a cache node would be removed from the farm when errors in deserialization of cached objects would occur due to serialised data not being read from the stream in entirety. The code also contains enhancements to better surface serialization exceptions to aid in the debugging process. This is also specifically targeted at the memcached implementation. This is important when moving from something like memory or Asp.Web caching mechanisms to memcached where the serialization rules are not as lenient. There are a few other minor bug fixes, code cleanup and a little refactoring. Minor feature addition In addition to this bug fix, many people have asked for a single setting to either enable or disable the cache.In this version, you can disable the cache by setting the IsCacheEnabled flag to false in the application configuration file. Something like the example below: <Glav.CacheAdapter.MainConfig> <setting name="CacheToUse" serializeAs="String"> <value>memcached</value> </setting> <setting name="DistributedCacheServers" serializeAs="String"> <value>localhost:11211</value> </setting> <setting name="IsCacheEnabled" serializeAs="String"> <value>False</value> </setting> </Glav.CacheAdapter.MainConfig> Your reasons to use this feature may vary (perhaps some performance testing or problem diagnosis). At any rate, disabling the cache will cause every attempt to retrieve data from the cache, resulting in a cache miss and returning null. If you are using the ICacheProvider with the delegate/Func<T> syntax to populate the cache, this delegate method will get executed every single time. For example, when the cache is disabled, the following delegate/Func<T> code will be executed every time: var data1 = cacheProvider.Get<SomeData>("cache-key", DateTime.Now.AddHours(1), () => { // With the cache disabled, this data access code is executed every attempt to // get this data via the CacheProvider. var someData = new SomeData() { SomeText = "cache example1", SomeNumber = 1 }; return someData; }); One final note: If you access the cache directly via the ICache instance, instead of the higher level ICacheProvider API, you bypass this setting and still access the underlying cache implementation. Only the ICacheProvider instance observes the IsCacheEnabled setting. Thanks to those individuals who have used this library and provided feedback. Ifyou have any suggestions or ideas, please submit them to the issue register on bitbucket (which is where you can grab all the source code from too)

• vmware player xorg driver broke after ubuntu 12.04 LTS automatic system update on 06/07/2014

  - by user291828

  I am running Ubuntu 12.04 LTS as a virtual machine on a Windows 7 host using vmware player 6.0.2. On Sat. 06/07/2014, Ubuntu performed an automatic system update as it does regularly, however after reboot, the display driver seems to be broken which causes the screen to split into many identical panels. This pretty much rendered the VM unusable. Below is the log entry for that update from /var/log/apt/history.log It appears that at least one of these updates have caused this problem. The exact same problem has been reported on the vmware forum as well, see https://communities.vmware.com/message/2388776#2388776 So far I have not been able so find a solution.

• A more elegant way of embedding a SOAP security header in Silverlight 4

  - by Your DisplayName here!

  The current situation with Silverlight is, that there is no support for the WCF federation binding. This means that all security token related interactions have to be done manually. Requesting the token from an STS is not really the bad part, sending it along with outgoing SOAP messages is what’s a little annoying. So far you had to wrap all calls on the channel in an OperationContextScope wrapping an IContextChannel. This “programming model” was a little disruptive (in addition to all the async stuff that you are forced to do). It seems that starting with SL4 there is more support for traditional WCF extensibility points – especially IEndpointBehavior, IClientMessageInspector. I never read somewhere that these are new features in SL4 – but I am pretty sure they did not exist in SL3. With the above mentioned interfaces at my disposal, I thought I have another go at embedding a security header – and yeah – I managed to make the code much prettier (and much less bizarre). Here’s the code for the behavior/inspector: public class IssuedTokenHeaderInspector : IClientMessageInspector {     RequestSecurityTokenResponse _rstr;       public IssuedTokenHeaderInspector(RequestSecurityTokenResponse rstr)     {         _rstr = rstr;     }       public void AfterReceiveReply(ref Message reply, object correlationState)     { }       public object BeforeSendRequest(ref Message request, IClientChannel channel)     {         request.Headers.Add(new IssuedTokenHeader(_rstr));                  return null;     } }   public class IssuedTokenHeaderBehavior : IEndpointBehavior {     RequestSecurityTokenResponse _rstr;       public IssuedTokenHeaderBehavior(RequestSecurityTokenResponse rstr)     {         if (rstr == null)         {             throw new ArgumentNullException();         }           _rstr = rstr;     }       public void ApplyClientBehavior(       ServiceEndpoint endpoint, ClientRuntime clientRuntime)     {         clientRuntime.MessageInspectors.Add(new IssuedTokenHeaderInspector(_rstr));     }       // rest omitted } This allows to set up a proxy with an issued token header and you don’t have to worry anymore with embedding the header manually with every call: var client = GetWSTrustClient();   var rst = new RequestSecurityToken(WSTrust13Constants.KeyTypes.Symmetric) {     AppliesTo = new EndpointAddress("https://rp/") };   client.IssueCompleted += (s, args) => {     _proxy = new StarterServiceContractClient();     _proxy.Endpoint.Behaviors.Add(new IssuedTokenHeaderBehavior(args.Result));   };   client.IssueAsync(rst); Since SL4 also support the IExtension<T> interface, you can also combine this with Nicholas Allen’s AutoHeaderExtension.

• Tuple - .NET 4.0 new feature

  - by nmarun

  Something I hit while playing with .net 4.0 – Tuple. MSDN says ‘Provides static methods for creating tuple objects.’ and the example below is: 1: var primes = Tuple.Create(2, 3, 5, 7, 11, 13, 17, 19); Honestly, I’m still not sure with what intention MS provided us with this feature, but the moment I saw this, I said to myself – I could use it instead of anonymous types. In order to put this to test, I created an XML file: 1: <Activities> 2: <Activity id="1" name="Learn Tuples" eventDate="4/1/2010" /> 3: <Activity id="2" name="Finish Project" eventDate="4/29/2010" /> 4: <Activity id="3" name="Attend Birthday" eventDate="4/17/2010" /> 5: <Activity id="4" name="Pay bills" eventDate="4/12/2010" /> 6: </Activities> In my console application, I read this file and let’s say I want to pull all the attributes of the node with id value of 1. Now, I have two ways – either define a class/struct that has these three properties and use in the LINQ query or create an anonymous type on the fly. But if we go the .NET 4.0 way, we can do this using Tuples as well. Let’s see the code I’ve written below: 1: var myActivity = (from activity in loaded.Descendants("Activity") 2:       where (int)activity.Attribute("id") == 1 3:       select Tuple.Create( 4: int.Parse(activity.Attribute("id").Value), 5: activity.Attribute("name").Value, 6: DateTime.Parse(activity.Attribute("eventDate").Value))).FirstOrDefault(); Line 3 is where I’m using a Tuple.Create to define my return type. There are three ‘items’ (that’s what the elements are called) in ‘myActivity’ type.. aptly declared as Item1, Item2, Item3. So there you go, you have another way of creating anonymous types. Just out of curiosity, wanted to see what the type actually looked like. So I did a: 1: Console.WriteLine(myActivity.GetType().FullName); and the return was (formatted for better readability): "System.Tuple`3[                            [System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],                            [System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],                            [System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]                           ]" The `3 specifies the number of items in the tuple. The other interesting thing about the tuple is that it knows the data type of the elements it’s holding. This is shown in the above snippet and also when you hover over myActivity.Item1, it shows the type as an int, Item2 as string and Item3 as DateTime. So you can safely do: 1: int id = myActivity.Item1; 2: string name = myActivity.Item2; 3: DateTime eventDate = myActivity.Item3; Wow.. all I can say is: HAIL 4.0.. HAIL 4.0.. HAIL 4.0

• A Reusable Builder Class for .NET testing

  - by Liam McLennan

  When writing tests, other than end-to-end integration tests, we often need to construct test data objects. Of course this can be done using the class’s constructor and manually configuring the object, but to get many objects into a valid state soon becomes a large percentage of the testing effort. After many years of painstakingly creating builders for each of my domain objects I have finally become lazy enough to bother to write a generic, reusable builder class for .NET. To use it you instantiate a instance of the builder and configuring it with a builder method for each class you wish it to be able to build. The builder method should require no parameters and should return a new instance of the type in a default, valid state. In other words the builder method should be a Func<TypeToBeBuilt>. The best way to make this clear is with an example. In my application I have the following domain classes that I want to be able to use in my tests: public class Person { public string Name { get; set; } public int Age { get; set; } public bool IsAndroid { get; set; } } public class Building { public string Street { get; set; } public Person Manager { get; set; } } The builder for this domain is created like so: build = new Builder(); build.Configure(new Dictionary<Type, Func<object>> { {typeof(Building), () => new Building {Street = "Queen St", Manager = build.A<Person>()}}, {typeof(Person), () => new Person {Name = "Eugene", Age = 21}} }); Note how Building depends on Person, even though the person builder method is not defined yet. Now in a test I can retrieve a valid object from the builder: var person = build.A<Person>(); If I need a class in a customised state I can supply an Action<TypeToBeBuilt> to mutate the object post construction: var person = build.A<Person>(p => p.Age = 99); The power and efficiency of this approach becomes apparent when your tests require larger and more complex objects than Person and Building. When I get some time I intend to implement the same functionality in Javascript and Ruby. Here is the full source of the Builder class: public class Builder { private Dictionary<Type, Func<object>> defaults; public void Configure(Dictionary<Type, Func<object>> defaults) { this.defaults = defaults; } public T A<T>() { if (!defaults.ContainsKey(typeof(T))) throw new ArgumentException("No object of type " + typeof(T).Name + " has been configured with the builder."); T o = (T)defaults[typeof(T)](); return o; } public T A<T>(Action<T> customisation) { T o = A<T>(); customisation(o); return o; } }
