  • Silverlight ProgressBar issues with Binding

    - by Chris Skardon
    The ProgressBar pretty much does what it says on the tin, displays progress, in a bar form (well, by default anyhow). It’s pretty simple to use: <ProgressBar Minimum="0" Maximum="100" Value="50"/> Gives you a progress bar with 50% of it filled: Easy! But of course, we’re wanting to use binding to change the value, again, pretty easy, have a ViewModel with a ‘Value’ in it, and bind: <ProgressBar Minimum="0" Maximum="100" Value="{Binding Value}"/> Spiffy, and whilst we’re at it, why not bind the Maximum value as well – after all, we can’t be sure of the size of the progress, and it’s a pain to have to work out the percentage (when the progress bar can do it for us): <ProgressBar Minimum="0" Maximum="MaximumValue" Value="{Binding Value}"/> Right, this will work absolutely fine. Or will it??? On the face of it, it looks good, and testing it shows no issues, until at one point we go from: Maximum = 100; Value = 90; to Maximum=60; Value=50; On the face of it not unreasonable. The problem is more obvious if we look at the states of the properties after each set (initially Maximum is set at 1, Value = 0): Code Maximum Value Value < Maximum Maximum = 100; 100 0 True Value = 90; 100 90 True Maximum = 60; 60 90 False Value = 50; 60 50 True Everything is good until the Value is less than the Maximum, at this point the Progress Bar breaks. That’s right, it no longer updates itself, it will always look 100% full. The simple solution – always ensuring you set Value before Maximum is fine unless you’re using a ProgressBar in a less controlled environment – where for example you’re setting a ‘container’ with both values at the same time. The example I have is in a DataTemplate, I have a DataTemplate for a BusyIndicator, (specifically the BusyContentTemplate). The binding works this way: <BusyIndicator BusyContent="{Binding BusyContent}" BusyContentTemplate="{Binding ProgressTemplate}"/> With the template as the ProgressBar defined above… I was setting my BusyContent like this: BusyContent = content; aaaaaand finally, ‘content’ is a class: public class ContentClass : INotifyPropertyChanged { //Obviously this is properly implemented… public double Maximum { get;set;} public double Value { get;set;} } Soooo… As I was replacing the BusyContent wholesale, the order of the binding being set was outside of my control, so – how to go about it? Basically? Fudge it. Modify the ContentClass to include a method: public void Update(double value, double max) { Value = value; Maximum = max; } and change where the setting is to be: BusyContent.Update(content.Value, content.Maximum); Thereby getting the order correct.. Obvious really. Meh :|

  • SortList duplicated key, but it shouldn't

    - by Luca
    I have a class which implements IList interface. I requires a "sorted view" of this list, but without modifying it (I cannot sort directly the IList class). These view shall be updated when the original list is modified, keeping items sorted. So, I've introduced a SortList creation method which create a SortList which has a comparer for the specific object contained in the original list. Here is the snippet of code: public class MyList<T> : ICollection, IList<T> { ... public SortedList CreateSortView(string property) { try { Lock(); SortListView sortView; if (mSortListViews.ContainsKey(property) == false) { // Create sorted view sortView = new SortListView(property, Count); mSortListViews.Add(property, sortView); foreach (T item in Items) sortView.Add(item); } else sortView = mSortListViews[property]; sortView.ReferenceCount++; return (sortView); } finally { Unlock(); } } public void DeleteSortView(string property) { try { Lock(); // Unreference sorted view mSortListViews[property].ReferenceCount--; // Remove sorted view if (mSortListViews[property].ReferenceCount == 0) mSortListViews.Remove(property); } finally { Unlock(); } } protected class SortListView : SortedList { /// <summary> /// /// </summary> /// <param name="property"></param> /// <param name="capacity"></param> public SortListView(string property, int capacity) : base(new GenericPropertyComparer(typeof(T).GetProperty(property, BindingFlags.Instance | BindingFlags.Public)), capacity) { } /// <summary> /// Reference count. /// </summary> public int ReferenceCount = 0; /// <summary> /// /// </summary> /// <param name="item"></param> public void Add(T item) { Add(item, item); } /// <summary> /// /// </summary> /// <param name="item"></param> public void Remove(T item) { // Base implementation base.Remove(item); } /// <summary> /// Compare object on a generic property. /// </summary> class GenericPropertyComparer : IComparer { #region Constructors /// <summary> /// Construct a GenericPropertyComparer specifying the property to compare. /// </summary> /// <param name="property"> /// A <see cref="PropertyInfo"/> which specify the property to be compared. /// </param> /// <remarks> /// The <paramref name="property"/> parameter imply that the compared objects have the specified property. The property /// must be readable, and its type must implement the IComparable interface. /// </remarks> public GenericPropertyComparer(PropertyInfo property) { if (property == null) throw new ArgumentException("property doesn't specify a valid property"); if (property.CanRead == false) throw new ArgumentException("property specify a write-only property"); if (property.PropertyType.GetInterface("IComparable") == null) throw new ArgumentException("property type doesn't IComparable"); mSortingProperty = property; } #endregion #region IComparer Implementation public int Compare(object x, object y) { IComparable propX = (IComparable)mSortingProperty.GetValue(x, null); IComparable propY = (IComparable)mSortingProperty.GetValue(y, null); return (propX.CompareTo(propY)); } /// <summary> /// Sorting property. /// </summary> private PropertyInfo mSortingProperty = null; #endregion } } /// <summary> /// Sorted views of this ReactList. /// </summary> private Dictionary<string, SortListView> mSortListViews = new Dictionary<string, SortListView>(); } Practically, class users request to create a SortListView specifying the name of property which determine the sorting, and using the reflection each SortListView defined a IComparer which keep sorted the items. Whenever an item is added or removed from the original list, every created SortListView will be updated with the same operation. This seems good at first chance, but it creates me problems since it give me the following exception when adding items to the SortList: System.ArgumentException: Item has already been added. Key in dictionary: 'PowerShell_ISE [C:\Windows\sysWOW64\WindowsPowerShell\v1.0\PowerShell_ISE.exe]' Key being added: 'PowerShell_ISE [C:\Windows\system32\WindowsPowerShell\v1.0\PowerShell_ISE.exe]' As you can see from the exception message, thrown by SortedListView.Add(object), the string representation of the key (the list item object) is different (note the path of the executable). Why SortList give me that exception? To solve this I tried to implement a GetHashCode implementation for the underlying object, but without success: public override int GetHashCode() { return ( base.GetHashCode() ^ mApplicationName.GetHashCode() ^ mApplicationPath.GetHashCode() ^ mCommandLine.GetHashCode() ^ mWorkingDirectory.GetHashCode() ); }

  • Sublime text 2 syntax highlighter?

  • Styles for XAML (Silverlight &amp; WPF)

    - by GeekAgilistMercenary
    This is a quick walk through of how to setup things for skinning within a XAML Application.  First thing, find the App.xaml file within the WPF or Silverlight Project. Within the App.xaml file set some default styles for your controls.  I set the following for a button, label, and border control for an application I am creating. Button Control <Style x:Key="ButtonStyle" TargetType="Button"> <Setter Property="FontFamily" Value="Arial" /> <Setter Property="FontWeight" Value="Bold" /> <Setter Property="FontSize" Value="14" /> <Setter Property="Width" Value="180" /> <Setter Property="Height" Value="Auto" /> <Setter Property="Margin" Value="8" /> <Setter Property="Padding" Value="8" /> <Setter Property="Foreground" Value="AliceBlue" /> <Setter Property="Background" > <Setter.Value> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="Black" Offset="0" /> <GradientStop Color="#FF5B5757" Offset="1" /> </LinearGradientBrush> </Setter.Value> </Setter> </Style> Label Control <Style x:Key="LabelStyle" TargetType="Label"> <Setter Property="Width" Value="Auto"/> <Setter Property="Height" Value="28" /> <Setter Property="Foreground" Value="Black"/> <Setter Property="Margin" Value="8"/> </Style> Border Control <Style x:Key="BorderStyle" TargetType="Border"> <Setter Property="BorderThickness" Value="4"/> <Setter Property="Width" Value="Auto"/> <Setter Property="Height" Value="Auto" /> <Setter Property="Margin" Value="0,8,0,0"/> <Setter Property="CornerRadius" Value="18"/> <Setter Property="BorderBrush"> <Setter.Value> <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5"> <GradientStop Color="CornflowerBlue" Offset="0" /> <GradientStop Color="White" Offset="1" /> </LinearGradientBrush> </Setter.Value> </Setter> </Style> These provide good examples of setting individual properties to a default, such as; <Setter Property="Width" Value="Auto"/> <Setter Property="Height" Value="Auto" /> Also for settings a more complex property, such as with a LinearGradientBrush; <Setter Property="BorderBrush"> <Setter.Value> <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5"> <GradientStop Color="CornflowerBlue" Offset="0" /> <GradientStop Color="White" Offset="1" /> </LinearGradientBrush> </Setter.Value> </Setter> These property setters should be located between the opening and closing <Application.Resources></Application.Resources> tags. <Application x:Class="ScorecardAndDashboard.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="MainWindow.xaml"> <Application.Resources> </Application.Resources> </Application> Now in the pages, user controls, or whatever you are marking up with XAML, for the Style Property just set a StaticResource such as shown below. <!-- Border Control --> <Border Name="borderPollingFrequency" Style="{StaticResource BorderStyle}"> <!-- Label Control --> <Label Content="Trigger Name:" Style="{StaticResource LabelStyle}"></Label> <!-- Button Control --> <Button Content="Save Schedule" Name="buttonSaveSchedule" Style="{StaticResource ButtonStyle}" HorizontalAlignment="Right"/> That's it.  Simple as that.  There are other ways to setup resource files that are separate from the App.xaml, but the App.xaml file is always a good quick place to start.  As moving the styles to a specific resource file later is a mere copy and paste. Original post is available along with other technical ramblings.

  • How to query with the datetime value using LINQ to XML ?

    - by Shailesh Jaiswal
    I am developing window phone 7 application in silverlight. I am new to the silverlight. I am also new to LINQ to XML. In my application the user select the date & submit some transaction details into the application. The details gets stored in XML File. I am using the custom date control in my application for the date selection as follows private void DatePicker_ValueChanged(object sender, DateTimeValueChangedEventArgs e) { AppObj = Application.Current as App; AppObj.date = (DateTime)EntryDate.Value; } Then the value of AppObj.date gets stored in the XML file. Sometimes I use the DateTime.Now to store the date in the XML File. Now I want to generate the report of submitted transaction details by querying through LINQ to XML. I want to generate the report for today's date, current week & current month. For this purpose I am using the following code public void GetTransactionObjects(String strXMLFile, DateTime VDateTime) { XDocument doc = null; XMLFileManager XMLDocObj = new XMLFileManager(); doc = XMLDocObj.LoadXMLFile(strXMLFile); var vTransaction = from s in doc.Descendants("Transaction") .Where(x => x.Element("Current_Date").Value == VDateTime.ToShortDateString()) select new Transaction(s); this.Clear(); AddRange(vTransaction); } The Transaction class contains the following constructor. public Transaction(XElement xElement) { Transaction_ID = Convert.ToInt32(xElement.Element("Transaction_ID").Value.ToString()); TransactionType_ID = Convert.ToInt32(xElement.Element("TransactionType_ID").Value.ToString()); Alphabet_ID = Convert.ToInt32(xElement.Element("Alphabet_ID").Value.ToString()); ID = Convert.ToInt32(xElement.Element("ID").Value.ToString()); SubCategory_ID = Convert.ToInt32(xElement.Element("SubCategory_ID").Value.ToString()); Item_ID = Convert.ToInt32(xElement.Element("Item_ID").Value.ToString()); Currency_ID = Convert.ToInt32(xElement.Element("Currency_ID").Value.ToString()); InputTypeMethod_ID = Convert.ToInt32(xElement.Element("InputTypeMethod_ID").Value.ToString()); Principle = Convert.ToInt32(xElement.Element("InputTypeMethod_ID").Value.ToString()); Interest = Convert.ToInt32(xElement.Element("Interest").Value.ToString()); ROI = Convert.ToInt32(xElement.Element("InputTypeMethod_ID").Value.ToString()); Amount = Convert.ToInt32(xElement.Element("InputTypeMethod_ID").Value.ToString()); Current_Date = Convert.ToDateTime(xElement.Element("Current_Date").Value.ToString()); } In the XML File the value gets stored for date & time. The value gets stored as follows 0 0 3 0 0 0 3 0 0 0 0 5000 2010-12-31T18:08:23.433+05:30 Look at the node <Current_Date>2010-12-31T18:08:23.433+05:30</Current_Date> The date format is yyyy-mm-dd. Now how should I write the following query to get all the submitted transaction details for today's date ? var vTransaction = from s in doc.Descendants("Transaction") .Where(x => x.Element("Current_Date").Value == VDateTime.ToShortDateString()) select new Transaction(s); Similarly how should I write the query to get all the transaction details for the current week & current month? Can you please provide me any code or link through which I can resolve the above issue ? If I am doing anything wrong then please guide me.

  • StackOverflowException in c# when no local variable in the function

    - by dnkulkarni
    when i do this static void Main() { Main(); } I receive stackoverflow exception. As i have read so far about C# they say ONLY local variable of value types (and short living ones) will go on stack. But here in the code there are no local variable to go on stack then what overflows it ? I know from assembly code line Perspective that reference to Main() will go on stack too ? Is that right ?

  • What makes the availability of both primitive and object-wrapped values in JavaScript useful?

    - by Delan Azabani
    I wrote a blog post a while ago detailing how the availability of both primitive and object-wrapped value types in JavaScript (for things such as Number, String and Boolean) causes trouble, including but not limited to type-casting to a boolean (e.g. object-wrapped NaN, "" and false actually type-cast to true). My question is, with all this confusion and problems, is there any benefit to JavaScript having both types of values for the built-in classes?

  • Does Java support default parameter values?

    - by gnavi
    I came across some Java code that had the following structure: public MyParameterizedFunction(String param1, int param2) { this(param1, param2, false); } public MyParameterizedFunction(String param1, int param2, boolean param3) { //use all three parameters here } I know that in C++ I can assign a parameter a default value. For example: void MyParameterizedFunction(String param1, int param2, bool param3=false); Does Java support this kind of syntax? Are there any reasons why this two step syntax is preferable?

  • Using a constructor for return.

    - by Fecal Brunch
    Hi, Just a quick question. I've written some code that returns a custom class Command, and the code I've written seems to work fine. I was wondering if there are any reasons that I shouldn't be doing it this way. It's something like this: Command Behavior::getCommand () { char input = 'x'; return Command (input, -1, -1); } Anyway, I read that constructors aren't meant to have a return value, but this works in g++. Thanks for any advice, Rhys

  • Can I make a LaTeX macro 'return' a filename?

    - by drfrogsplat
    I'm writing my thesis/dissertation and since its an on-going work I don't always have the actual images ready for the figures I put into my document, but for various reasons want to automatically have it substitute a dummy figure in place when the included graphics file doesn't exist. E.g. I can do something like \includegraphics[width=8cm]{\chapdir/figures/fluxcapacitor} (where \chapdir is a macro for my 'current' chapter directory, e.g. \def\chapdir{./ch_timetravel} and if there's no ./ch_timetravel/figures/fluxcapacitor.jpg it'll insert ./commands/dummy.jpg instead. I've structured my macros (perhaps naïvely?) so that I have a macro (\figFileOrDummy) that determines the appropriate file to include by checking if the argument provided to it exists, so that I can call \includegraphics[properties]{\figFileOrDummy{\chapdir/figures/fluxcapacitor}}. Except I'm getting various errors depending on how I try to call this, which seem to suggest that I'm approaching the problem in a fundamentally flawed way as far as 'good LaTeX programming' goes. Here's the macro to check if the file exists (and 'return' either filename or the dummy filename): \newcommand{\figFileOrDummy}[1]{% % Figure base name (no extension) to be used if the file exists \def\fodname{#1}% \def\dummyfig{commands/dummy}% % Check if output is PS (.EPS) or PDF (.JPG/.PDF/.PNG/...) figures \ifx\pdfoutput\undefined% % EPS figures only \IfFileExists{\fodname.eps}{}{\def\fodname{\dummyfig}}% \else% % Check existence of various extensions: PDF, TIF, TIFF, JPG, JPEG, PNG, MPS \def\figtest{0}% flag below compared to this value \IfFileExists{\fodname.pdf}{\def\figfilenamefound{1}}{\def\figfilenamefound{0}}% \IfFileExists{\fodname.jpg}{\def\figfilenamefound{1}}{}% \IfFileExists{\fodname.png}{\def\figfilenamefound{1}}{}% % and so on... % If no files found matching the filename (flag is 0) then use the dummy figure \ifx\figfilenamefound\figtest% \def\fodname{\dummyfig}% \fi% \fi% % 'return' the filename \fodname% }% Alternatively, here's a much simpler version which seems to have similar problems: \newcommand{\figFileOrDummy}[1]{% \def\dummyfig{commands/dummy}% \dummyfig% } The \def commands seems to be processed after the expansion of the macro they're trying to define, so it ends up being \def {commands/dummy}... (note the space after \def) and obviously complains. Also it seems to treat the literal contents of the macro as the filename for \includegraphics, rather than resolving/expanding it first, so complains that the file '\def {commands/dummy}... .png' doesn't exist.. I've tried also doing something like \edef\figfilename{\figFileOrDummy{\chapdir/figures/fluxcapacitor}} to try to force it to make \figfilename hold just the value rather than the full macro, but I get an Undefined control sequence error complaining the variables I'm trying to \def in the \figFileOrDummy macro are undefined. So my question is either How do I make this macro expand properly?; or If this is the wrong way of structuring my macros, how should I actually structure such a macro, in order to be able to insert dummy/real figures automatically?; or Is there a package that already handles this type of thing nicely that I've overlooked? I feel like I'm missing something pretty fundamental here...

  • Why isn't this infinite recursion? How does default variable initialization work in VB.NET?

    - by froadie
    I just made an interesting mistake in my code: Dim endColumn As Integer = startColumn + endColumn - 1 The code was actually supposed to be: Dim endColumn As Integer = startColumn + numColumns - 1 The interesting thing is, I would think that this code should be recursive and loop indefinitely, as the initialization of endColumn sort of calls itself. However, it seems that the code just treats the uninitialized variable as a 0 and so I get startColumn + 0 - 1. What is happening here behind the scenes? When does a variable get assigned a default value?

    I have a table of many values where one column has the WO Number, and another column has the Resource ID. I need to be able to find all the WO numbers that do not have a resource value of "RW". Here is an example of the typical information. I need to be able to know that work order 5678 does not have an "RW" Resource ID. WO Number - Resource ID 1234 - IN 1234 - WE 1234 - AS 1234 - RW 5678 - PR 5678 - WE 5678 - IN 5678 - AS

  • jQuery(formElement).val(null) : inconsistent results in different browsers

    - by Shehi
    Code is here: http://jsfiddle.net/jf7t2/1/ Please run it on the latest versions of all browsers, and see for yourself. When the button is clicked, on: on Chrome (and Safari of course) it just doesn't select anything, instead creates some ghostly empty option on Firefox and Opera, it works the way I expect and want it to work, resets the element value on Explorer, it does nothing So, which one is expected behaviour? Thanks.

  • At most how many customized P3 attributes could be added into Agile?

    - by Jie Chen
    I have one customer/Oracle Partner Consultant asking me such question: how many customized attributes can be allowed to add to Agile's subclass Page Three? I never did research against this because Agile User Guide never says this and theoretically Agile supports unlimited amount of customized attributes, unless the browser itself cannot handle them in allocated memory. However my customers says when to add almost 1000 attributes, the browser (Web Client) will not show any Page Three attributes, including all the out-of-box attributes. Let's see why. Analysis It is horrible to add 1000 attributes manually. Let's do it by a batch SQL like below to add them to Item's subclass Page Three tab. Do not execute below SQL because it will not take effect due to your different node id. CREATE OR REPLACE PROCEDURE createP3Text(v_name IN VARCHAR2) IS v_nid NUMBER; v_pid NUMBER; BEGIN select SEQNODETABLE.nextval into v_nid from dual; Insert Into nodeTable ( id,parentID,description,objType,inherit,helpID,version,name ) values ( v_nid,2473003, v_name ,1,0,0,0, v_name);

Check here http://ora-01795.ora-code.com If you need Oracle Agile's final solution, please contact Oracle Agile Support. Performance Below two screenshot are jvm heap usage from before-SQL and after-SQL. We can see there is no big memory gap between two cases. So definitely there is no performance impact to Agile Application Server unless you have more than 1000 attributes for EACH of your dozens of  subclasses. And for client, 1000 attributes should not impact the browser's performance because in HTML we only use dt and dd for each attribute's pair: label and value. It is quite lightweight.

  • can not set the bool value of app setting

    - by user262325
    Hello everyone I use the codes below to read and write a bool value from my application: -(void)SaveAppSetting; {     NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];     bool b=true;     [defaults setBool:b forKey:@"AnyKey"]; [defaults synchronize]; } -(void)LoadAppSetting; {     NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];     bool b=[defaults boolForKey: @"AnyKey"] ; } I found that "LoadAppSetting" worked well, it could get the correct value of item with key "AnyKey". The function "SaveAppSetting" looked like no function, it reported no error, but it can not change value of the item with key "AnyKey". "AnyKey" setting in Setting bundle is item Dictionary Type String PSToggleSwitchSpecifier Title String AnyKey's Title Key String AnyKey DefaultValue Boolean Checked Is there any person met the same problem? Thanks interdev

  • Insert rows into MySQL table while changing one value

    - by Jonathan
    Hey all- I have a MySQL table that defines values for a specific customer type. | CustomerType | Key Field 1 | Key Field 2 | Value | Each customer type has 10 values associated with it (based on the other two key fields). I am creating a new customer type (TypeB) that is exactly the same as another customer type (TypeA). I want to insert "TypeB" as the CustomerType but then just copy the values from TypeA's rows for the other three fields. Is there an SQL insert statement to make this happen? Somthing like: insert into customers(customer_type, key1, key2, value) values "TypeB" union select key1, key2, value from customers where customer_type = "TypeA" Thanks- Jonathan

  • How do I get the NextVal from an oracle Sequence thru NHibernate

    - by trainer
    I am working on c# .net 4.0 and using NHibernate to talk with an Oracle DB. You would think something as simple as this is already addressed somewhere but sadly its not. I need the NextVal from an Oracle sequence. I do not need to insert it a database as part of an Id or Primary key. I just need to use the next val on the c# side. Can somebody help me out with xml mapping and C# file(or a link) to achieve this. Thanks. Something like int NextValueOfSequence = GetNextValueofSequence(); public int GetNextValueOfSequence() { // Access NHibernate to return the next value of the sequence. }

  • Value [...] not a valid choice, django-updown

    - by tamara
    I am trying to implemet django-updown https://github.com/weluse/django-updown. When I try to add vote trough the admin panel it says Value 1 not a valid choice. This is the models.py from the application: _SCORE_TYPE_CHOICES = ( ('-1', 'DISLIKE'), ('1', 'LIKE'), ) SCORE_TYPES = dict((value, key) for key, value in _SCORE_TYPE_CHOICES) class Vote(models.Model): content_type = models.ForeignKey(ContentType, related_name="updown_votes") object_id = models.PositiveIntegerField() key = models.CharField(max_length=32) score = models.SmallIntegerField(choices=_SCORE_TYPE_CHOICES) user = models.ForeignKey(User, blank=True, null=True, related_name="updown_votes") ip_address = models.IPAddressField() date_added = models.DateTimeField(default=datetime.datetime.now, editable=False) date_changed = models.DateTimeField(default=datetime.datetime.now, editable=False) Do you have an idea what could be wrong?

Now I want the same to use it after formatting my disk. I found a software Volume Activation Manager tool on the windows website. I am not sure how to use it. Please tell me how can I reuse my key?

  • What is the correct way to use Chef-server's 'validation key'?

    - by Socio
    It seems to me that the recommended way of adding clients to a chef server - or my understanding of it - is flawed. from the docs: When the chef-client runs, it checks if it has a client key. If the client key does not exist, it then attempts to "borrow" the validation client's identity to register itself with the server. In order to do that, the validation client's private key needs to be copied to the host and placed in /etc/chef/validation.pem. So the "validation key" is basically the superuser credential, allowing anyone who possesses it full access to the chef server? Am I reading this right? Surely the correct model would be for clients to generate their own keypair, and submit the public key to the chef server. Clients should never need access to this superuser "validation key". How can I do it in this, more secure, manner?
