• What's the standard behaviour for an out parameter when a TryXxxx method returns false?

  - by Matt Lacey

  Assuming a method with the following signature bool TryXxxx(object something, out int toReturn) What is it acceptable for toReturn to be if TryXxxx returns false? In that it's infered that toReturn should never be used if TryXxxx fails does it matter? If toReturn was a nulable type, then it would make sense to return null. But int isn't nullable and I don't want to have to force it to be. If toReturn is always a certain value if TryXxxx fails we risk having the position where 2 values could be considered to indicate the same thing. I can see this leading to potential possible confusion if the 'default' value was returned as a valid response (when TryXxxx returns true). From an implementation point if view it looks like having toReturn be a[ny] value is easiest, but is there anything more important to consider?

• Why am I getting 'undefined method' exceptions when executing 'run_list add', 'run_list remove' and 'rackspace server delete'?

  - by Peter Groves

  [Originally posted this to opscode forum, got no response] I’m testing out a free hosted chef-server account and multiple subcommands are failing with ‘Unexpected Errors’. Perhaps my version and the server version are incompatible? OS: Ubuntu 12.04LTS Local Chef: 10.12.0 (Installed through gem) Local Ruby: 1.8.7 Also, the workstation machine has been manually configured, but the client(s) I’ve been experimenting with are launched with the Rackspace plugin (using ‘knife rackspace server create…’) The problem commands seem to fail when talking to the host chef-server, however, before it ever tries to modify the client, so I don’t believe that’s where the problem exists. The virtual-servers that are launched by ‘knife rackspace server create’ are launched properly but then deleting them with knife fails. If I include a recipe in the run_list when I create the server, the recipe is properly added to the run_list. If I try to add it later or remove the one that there server was initialized with, those commands fail. Here is the output of a few relevant commands (with stacktraces): https://gist.github.com/7100ada3fd6690113697

• Getting an exception when trying to use extension method with SortedDictionary... why?

  - by Polaris878

  I'm trying to place custom objects into a sorted dictionary... I am then trying to use an extension method (Max()) on this sorted dictionary. However, I'm getting the exception: "At least one object must implement IComparable". I don't understand why I'm getting that, as my custom object obviously implements IComparable. Here is my code: public class MyDate : IComparable<MyDate> { int IComparable<MyDate>.CompareTo(MyDate obj) { if (obj != null) { if (this.Value.Ticks < obj.Value.Ticks) { return 1; } else if (this.Value.Ticks == obj.Value.Ticks) { return 0; } else { return -1; } } } public MyDate(DateTime date) { this.Value = date; } public DateTime Value; } class Program { static void Main(string[] args) { SortedDictionary<MyDate, int> sd = new SortedDictionary<MyDate,int>(); sd.Add(new MyDate(new DateTime(1)), 1); sd.Add(new MyDate(new DateTime(2)), 2); Console.WriteLine(sd.Max().Value); // Throws exception!! } } What on earth am I doing wrong???

• Stopping cookies being set from a domain (aka "cookieless domain") to increase site performance

  - by Django Reinhardt

  I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

• Apache, logerror and logrotate: what is the best method?

  - by OlivierDofus

  Hi! Here's a vhost example of my sites: <VirtualHost *:80> DocumentRoot /datas/web/woog ServerName woog.com ServerAlias www.woog.com ErrorLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/error_log 86400" CustomLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/access_log 86400" combined DirectoryIndex index.php index.htm <Location /> Allow from All </Location> <Directory /*> Options FollowSymLinks AllowOverride Limit AuthConfig </Directory> </VirtualHost> I've got 12 sites running now. This gives something like: [Shake]:/sources/software/mod_log_rotate# ps x | grep rotate /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 [snap (as many error_log as virtual hosts)] /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 [snap (as many access_log as virtual hosts)] grep rotate [Shake]:/sources/software/mod_log_rotate# !!! I've been looking everywhere but I've only found mod_log_rotate. The "little" problem is that the author (very good C developper) explains: "Unfortunately Apache error logs are handled in such a way that we can't work the same log rotation magic on them. Like transfer logs they support piped logging though so you can still use rotatelogs for them. " So my question is: what would be the best way to handle multiple logs? If I just do a very classical log and I use the system's "logrotate" program couldn't this be a good deal? How would/do you deal with that? Thank you!

• Autocorrelation method for pitch determination.. whats d input data form..?

• Is there a method I can use across controllers and if so, how do I use it?

  - by Angela

  I have several controllers that take an instance of different classes each (Email, Call, Letter, etc) and they all have to go through this same substitution: @email.message.gsub!("{FirstName}", @contact.first_name) @email.message.gsub!("{Company}", @contact.company_name) @email.message.gsub!("{Colleagues}", @colleagues.to_sentence) @email.message.gsub!("{NextWeek}", (Date.today + 7.days).strftime("%A, %B %d")) @email.message.gsub!("{ContactTitle}", @contact.title ) So, for example, @call.message for Call, @letter.message for Letter, etcetera. This isn't very dry. I'd like to have something like def messagesub(asset) @asset.message.gsub.... end or something like that so I can just use messagesub method in each controller.

• Is there a standard method for assigning nameservers to servers in a Windows domain?

  - by HopelessN00b

  As the title asks, I'm wondering if there's any standard or "best practice" for how to actually assign nameservers (DNS) and manage the nameserver configuration for client servers on a Windows domain. I'm talking about the setting circled in the below image, in case the language of the question is not clear enough: This is for a large, multi-site environment, where ideally/hopefully all servers point at their site's Domain Controller as the primary DNS server, and a DNS server at a different site as the secondary DNS server. For simplicity's sake, we can say that the secondary server would be the Domain Controller at the home site for everyone, and there are no tertiary DNS servers (even though that's not actually the case). Try as I might, I can't seem to find a GPO setting for this (at least on FL 2003 R2, the Computer Configuration - Administrative Templates - Network - DNS Client - DNS Servers GPO is Supported on: Windows XP Professional only), and I find it rather hard to believe that the "best"/"standard" solution would therefore be either scripting up something to apply the DNS settings per site, or using a DHCP server to push those configurations out to the other servers via the DHCP Scope Options. So, is there a standard way of managing this configuration? (That's hopefully not "a script" or "DHCP Scope Option.)

• Can getAttribute() method of Tomcat ServletContext implementation be called without synchronization?

  - by oo_olo_oo

  I would like to read some parameters during servlet initializtion (in init() method), and store them among servlet context attributes (using getServletContext().setAttribute()). I would like to read these parameters later - during some request processing (using getServletContext().getAttribute()). So, the multiple threads could do this simultaneously. My question is if such an attempt is safe? Could I be sure that multi threaded calls to the getAttribute() don't mess up any internal state of the servlet context? Please take into account that I'm not going to call the setAttribute() anywhere besides the initialization. So, only calls to the getAttribute() are going to be done from multiple threads. But depending on the internal implementation, this also could be dangerous. So, any information about Tomcat's implementation would be appreciated.

• Filling in a multi-choice field in a Sharepoint Doc-Lib using SetDocsMetaInfo Frontpage Server Extentions RPC method

  - by notnot

  I've been given a big chunk of code which eventually calls upon the SetDocsMetaInfo method from Frontpage Server Extension RPC. This is easy enough for most document uploading and property updating, except when dealing with multichoice fields. I've been scouring through MSDN and I can't find anything on how to fill in multiple values for such a field. The general syntax for properties is something like this: [SR|default], with the type (string in this case) followed by a pipe and then the value to be written. Does anyone know the syntax for multichoice fields? references: MSDN: SetDocsMetaInfo

• MouseWheel Event Fire

  - by Rahat

  I have a problem on calling my private method on MouseWheel event. In fact my mouse wheel event gets fired properly when i only increment a variable or display something in Title bar etc. But when i want to call a private method, that method gets called only one time which is not the requirement i want to call that method depending on the speed of scroll i.e. when scroll is done one time slowly call the private method one time but when the scroll is done in high speed call the private method more than one time depending on the scroll speed. For further explanation i am placing the sample code which displays the value of i in Title bar and add it in the Listbox control properly depending on the scroll speed but when i want to call the private method more than one time depending upon the scroll speed, that method gets called only one time. public partial class Form1 : Form { ListBox listBox1 = new ListBox(); int i = 0; public Form1() { InitializeComponent(); // Settnig ListBox control properties this.listBox1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); this.listBox1.FormattingEnabled = true; this.listBox1.Location = new System.Drawing.Point(13, 13); this.listBox1.Name = "listBox1"; this.listBox1.Size = new System.Drawing.Size(259, 264); this.listBox1.TabIndex = 0; // Attaching Mouse Wheel Event this.listBox1.MouseWheel += new MouseEventHandler(Form1_MouseWheel); // Adding Control this.Controls.Add(this.listBox1); } void Form1_MouseWheel(object sender, MouseEventArgs e) { i++; this.Text = i.ToString(); this.listBox1.Items.Add(i.ToString()); // Uncomment the following line to call the private method // this method gets called only one time irrelevant of the // mouse wheel scroll speed. // this.LaunchThisEvent(); } private void Form1_Load(object sender, EventArgs e) { this.listBox1.Select(); } private void LaunchThisEvent() { // Display message each time // this method gets called. MessageBox.Show(i.ToString()); } } How to call the private method more than one time depending upon the speed of the mouse wheel scroll?

• Should I use a metaclass, class decorator, or override the __new__ method?

  - by 007brendan

  Here is my problem. I want the following class to have a bunch of property attributes. I could either write them all out like foo and bar, or based on some other examples I've seen, it looks like I could use a class decorator, a metaclass, or override the __new__ method to set the properties automagically. I'm just not sure what the "right" way to do it would be. class Test(object): def calculate_attr(self, attr): # do calculaty stuff return attr @property def foo(self): return self.calculate_attr('foo') @property def bar(self): return self.calculate_attr('bar')

• How can I hook up an IBAction method to a plain view for a touch up event?

  - by Thanks

  I have created a blank new view-based application project in Xcode. It generated a myProjectViewController and an nib for it. In that nib for that view controller, there is just one view. I wanted to test some event handling stuff and created an -(IBAction) method that will just log a "hello world" when I touch the view. But for some reason, IB doesn't give me a chance to hook up the action. What am I doing wrong there? I also tried to put a UIView as subview there. When I drag from that to File's Owner (whoose class is the myProjectViewController, where I have the IBAction in the header), doesn't even mention the IBAction. But it actually should, right?

• How to read a parameter passed to a facelet from a backing bean

  - by Antonio

  Hi, I've written a facelet, and a corresponding backing bean, that implements user management (addition, deletion and so on). I'd want to be able to perform some custom processing when, for instance, a new user is added. There is a "create" button in the facelet, whose click event is handled by its backing bean. At the end of the event handler, I'd want to be able to call a method of another backing bean, which is not known because ideally the facelet can be used in several pages, with different custom processing. I thought to implement this feature by providing to the facelet a backing bean name and a method name, like this: <myfacelet:subaccounts backingBean="myBackingBean" createListener="createListener" /> and at the end of the event handler call #{myBackingBean.createListener} someway. I'm using this method (along with some overloads) to obtain a MethodExpression: protected MethodExpression getMethodExpression(String beanName, String methodName, Class<?> expectedReturnType, Class<?>[] expectedParamTypes) { ExpressionFactory expressionFactory; MethodExpression method; ELContext elContext; String el; el = String.format("#{%s['%s']}", beanName, methodName); expressionFactory = getApplication().getExpressionFactory(); elContext = getFacesContext().getELContext(); method = expressionFactory.createMethodExpression(elContext, el, expectedReturnType, expectedParamTypes); return method; } and the click event handler should look like: public void saveSubaccountListener(ActionEvent event) { MethodExpression method; ... method = getMethodExpression( "backingBean", "createSubaccountListener", SubuserBean.class); if (method != null) method.invoke( getFacesContext().getELContext(), new Object[] { _editedSubuser }); } That works fine as long as I provide an existing bean name (myBackingBean), but if I use backingBean the invoke() doesn't work due to the following error: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'backingBean' resolved to null Is there a way I can retrieve from the facelet backing bean the value of a parameter that has been passed to the facelet? In my case, the value of backingBean, which should be myBackingBean? I've searched for and tried different solutions, but with no luck yet.

• Best method to redirect internal DNS to external website?

  - by ProfessionalAmateur

  We host several web based applications outside of intranet. The URL's to these applications are long, complex and overall not user friendly. Ex: http://hostingsite:port/approot/folder/folder/login.aspx <-- (production) http://hostingsite:port22/approot/folder/folder/login.aspx <-- (dev) http://hostingsite:port33/approot/folder/folder/login.aspx <-- (test) I'd like to create an internal DNS entry to allow users to access these sites with ease. Ex: http://prod --> http://hostingsite:port/approot/folder/folder/login.aspx http://dev --> http://hostingsite:port22/approot/folder/folder/login.aspx I'm not familiar with the DNS process and setup, as far as I know a DNS can only be redirected to an IP, but not to subdomains for directory paths as described above? Is this a correct assumption? I am thinking for throwing up an internal webserver that will listen to the internal DNS entries and redirect to the external sites. http://prod --> [internal webserver] --> redirect --> http://hostingsite:port/approot/folder/folder/login.aspx Is there a better way to do this?

• Which method of SQL Server 2005 or 2008 Replication is best for ease of field changes?

  - by Rick

  We need 15 minute warm updates from one SQL Server to another. Log Shipping looks good and appears easy to setup. We are also looking into Transactional Replication. The data only needs to copy one way. We have two main requirements: 1) The destination database needs to be a max 15 minute old copy of the source. It needs to re-try and get up-to-date if a network cable is unplugged for a while. 2) We would really like table (fields added or modified) changes in the source as easy as possible. Thanks in advance for all suggestions.

• Using nginx to rewrite urls inside outgoing responses

  - by Kev

  We have a customer with a site running on Apache. Recently the site has been seeing increased load and as a stop gap we want to shift all the static content on the site to a cookieless domains, e.g. http://static.thedomain.com. The application is not well understood. So to give the developers time to amend the code to point their links to the static content server (http://static.thedomain.com) I thought about proxying the site through nginx and rewriting the outgoing responses such that links to /images/... are rewritten as http://static.thedomain.com/images/.... So for example, in the response from Apache to nginx there is a blob of Headers + HTML. In the HTML returned from Apache we have <img> tags that look like: <img src="/images/someimage.png" /> I want to transform this to: <img src="http://static.thedomain.com/images/someimage.png" /> So that the browser upon receiving the HTML page then requests the images directly from the static content server. Is this possible with nginx (or HAProxy)? I have had a cursory glance through the docs but nothing jumped out at me except rewriting inbound urls.

• Have Microsoft changed how ASP.NET MVC deals with duplicate action method names?

  - by Jason Evans

  I might be missing something here, but in ASP.NET MVC 4, I can't get the following to work. Given the following controller: public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(string order1, string order2) { return null; } } and it's view: @{ ViewBag.Title = "Home"; } @using (Html.BeginForm()) { @Html.TextBox("order1")<br /> @Html.TextBox("order2") <input type="submit" value="Save"/> } When start the app, all I get is this: The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Index() on type ViewData.Controllers.HomeController System.Web.Mvc.ActionResult Index(System.String, System.String) on type ViewData.Controllers.HomeController Now, in ASP.NET MVC 3 the above works fine, I just tried it, so what's changed in ASP.NET MVC 4 to break this? OK there could be a chance that I'm doing something silly here, and not noticing it. EDIT: I notice that in the MVC 4 app, the Global.asax.cs file did not contain this: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); } which the MVC 3 app does, by default. So I added the above to the MVC 4 app but it fails with the same error. Note that the MVC 3 app does work fine with the above route. I'm passing the "order" data via the Request.Form. EDIT: In the file RouteConfig.cs I can see RegisterRoutes is executed, with the following default route: routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }); I still get the original error, regards ambiguity between which Index() method to call.

• Alternative method of viewing a database diagram in SQL Server to see what tables have gone missing?

  - by Triynko

  I have a database diagram for my database, but when I open it in SQL Server, I almost immediately get a message saying some permissions changed or tables in the diagram were dropped or renamed, and tables in the diagram vanish before I can even scroll over to see what or where they were. Basically, it's saying, "Hey, you know all that time you spent laying out tables in this diagram... half of them are going to vanish when you view it, and I'm not going to tell you which tables vanished or where they were in the diagram. You're just going to see a bunch of random empty spaces where tables used to be ;)" Ridiculous. So I thought that maybe if I look in the dbo.sysdiagrams table, I could look at some plain text definition of the diagram to get a clue about the names of the tables that went missing (because thier names were probably only changed slightly) or their coordinates in the diagram (because their spatial location would give me a clue as to what they were), so that I could re-add them, but I can't, because it's a binary definition. So, is there some other program I could use to view the existing database diagram that's not going to just drop and forget the missing tables without telling me what they were, or is this information lost and at the mercy of some SSMS-proprietary database diagram format and viewer which refuses to cooperate with me.

• Is there a convenient method to pull files from a server in an SSH session?

  - by tel

  I often SSH into a cluster node for work and after processing want to pull several results back to my local machine for analysis. Typically, to do this I use a local shell to scp from the server, but this requires a lot of path manipulation. I'd prefer to use a syntax like interactive FTP and just 'pull' files from the server to my local pwd. Another possible solution might be to have some way to automatically set up my client computer as an ssh alias so that something like scp results home:~/results would work as expected. Is there any obscure SSH trick that'll do this for me? Working from grawity's answer, a complete solution in config files is something like local .ssh/config: Host ex HostName ssh.example.com RemoteForward 10101 localhost:22 ssh.example.com .ssh/config: Host home HostName localhost Port 10101 which lets me do commands exactly like scp results home: transferring the file results to my home machine.

What can I look at here? function readShift(jsonString) { var shiftInfo = Sys.Serialization.JavaScriptSerializer.deserialize(jsonString); var listItems = ""; listItems += "<option value='0'>[Unassigned]</option>"; for (var i = 0; i < shiftInfo.ResourceList.length; i++) { listItems += "<option value='" + shiftInfo.ResourceList[i].id + "'>" + shiftInfo.ResourceList[i].name + "</option>"; } $("#" + resourceListId).html(listItems); };
