• zsh partially completion in aptitude/wajig

  - by mk_cafe

  I'm using wajig to install packages, however when i've changed my shell to zsh it turned out that zsh doesn't list all packages in completion list, for ex. apt-get install octave[TAB] (about 70 completions) but when i try wajig install octave[TAB] or aptitude install octave[TAB] zsh shows only 19 completions other shells i've tested (bash, fish) shows all ~70 completions in all 3 cases. So is there any way to 'fix' this completion in zsh?

• Can't use HTTPS with ServerXMLHTTP object

  - by Imraan

  I am supporting a Classic ASP application that connects to a payment gateway via HTTPS. Up until recently there have been no issues. A few days ago this broke without the code, IIS config or anything local changing. Its broken on at least 3 separate servers. The last run of Windows Updates was in late November, but bringing the servers' updates up date has not resolved the problem. A code snippet is below. Dim oHttp Dim strResult Set oHttp = CreateObject("MSXML2.ServerXMLHTTP") oHttp.setOption 2, 13056 oHttp.open "POST", SOAP_ENDPOINT, false oHttp.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8" oHttp.setRequestHeader "SOAPAction", SOAP_NS + "/" & SOAP_FUNCTION oHttp.send SOAP_REQUEST Below is a dump of the error object :- Number: -2147012852 Description: A certificate is required to complete client authentication Message: A certificate is required to complete client authentication I initially posted the question on Stackoverflow (http://stackoverflow.com/questions/9212985/cant-use-https-with-serverxmlhttp-object) thinking it was a code issue, but further investigation seems to point to a server issue.

• SQL update table from another table

  - by LtDan

  Using SQL in Access, trying to "Update" a table, with the user name, from another table. The 3rd line below (SQLnm2...) says error-2465 cant find field '|'. I've tried changing the expression many ways but no success. Any assistance would be greatly appreciated. Dim SQLnm As String Dim SQLnm2 As String SQLnm2 = SQLnm2 & "', '" & [Employees]![NBK] & "');" SQLnm = " Update tbl_DateTracking SET NBK = " SQLnm = SQLnm & "'" & SQLnm2 & "' WHERE " SQLnm = SQLnm & "CaseId = '" & CaseId & "' AND OCC_Scenario = '" & OCC_Scenario & "';" DoCmd.RunSQL SQLnm

• SQL UPDATE based on condition

  - by LtDan

  We need to update a table with the users id (NBK). The table with NBK also has the user status (0 - 1) and only one user will have 1 at a time. The challenage is to #1 capture the active user #2 update the other table with the user NBK. I hope the code below just has a simple syntex error that I cannot find? Dim nb As String Dim NBK As String nb = [Employees]![NBK] & "' WHERE " nb = nb & " " & [Employees]![Status] = '1' NBK = " Update tbl_DateTracking SET NBK = " NBK = NBK & "'" & nb & "' WHERE " NBK = NBK & "CaseId = '" & CaseId & "' AND OCC_Scenario = '" & OCC_Scenario & "' ;" DoCmd.RunSQL nb DoCmd.RunSQL NBK

• Excel macro to delete empty rows isn't stopping

  - by RocketGoal

  How do I make it stop after a certain amount of rows? I've taken a VBA course and my teacher explained how to delete empty rows. I'm now trying to put this in place but my macro isn't stopping. I thought I had limited it to 200 rows. I'm missing something important. Any pointers much appreciated. Sub RemoveRows() ' Remove rows from last blank cell Dim LastRow As Long Dim ISEmpty As Long 'Count how many records in the list. This is done so that the Do loop has a finish point. LastRow = Range("A200").End(xlUp).Row 'Start at the top of the list Range("A1").Select 'Loop until the end of the list Do While ActiveCell.Row < LastRow 'Assign number of non empty cells in the row ISEmpty = Application.CountA(ActiveCell.EntireRow) 'If ISEmpty = 0 then delete the row, if not move down a cell into the next row If ISEmpty = 0 Then ActiveCell.EntireRow.Delete Else ActiveCell.Offset(1, 0).Select End If Loop End Sub

• Entity Framework many-to-many using VB.Net Lambda

  - by bgs264

  Hello, I'm a newbie to StackOverflow so please be kind ;) I'm using Entity Framework in Visual Studio 2010 Beta 2 (.NET framework 4.0 Beta 2). I have created an entity framework .edmx model from my database and I have a handful of many-to-many relationships. A trivial example of my database schema is Roles (ID, Name, Active) Members (ID, DateOfBirth, DateCreated) RoleMembership(RoleID, MemberID) I am now writing the custom role provider (Inheriting System.Configuration.Provider.RoleProvider) and have come to write the implementation of IsUserInRole(username, roleName). The LINQ-to-Entity queries which I wrote, when SQL-Profiled, all produced CROSS JOIN statements when what I want is for them to INNER JOIN. Dim query = From m In dc.Members From r In dc.Roles Where m.ID = 100 And r.Name = "Member" Select m My problem is almost exactly described here: http://stackoverflow.com/questions/553918/entity-framework-and-many-to-many-queries-unusable I'm sure that the solution presented there works well, but whilst I studied Java at uni and I can mostly understand C# I cannot understand this Lambda syntax provided and I need to get a similar example in VB. I've looked around the web for the best part of half a day but I'm not closer to my answer. So please can somebody advise how, in VB, I can construct a LINQ statement which would do this equivalent in SQL: SELECT rm.RoleID FROM RoleMembership rm INNER JOIN Roles r ON r.ID = rm.RoleID INNER JOIN Members m ON m.ID = rm.MemberID WHERE r.Name = 'Member' AND m.ID = 101 I would use this query to see if Member 101 is in Role 3. (I appreciate I probably don't need the join to the Members table in SQL but I imagine in LINQ I'd need to bring in the Member object?) UPDATE: I'm a bit closer by using multiple methods: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim count As Integer Using dc As New CBLModel.CBLEntities Dim persons = dc.Members.Where(AddressOf myTest) count = persons.Count End Using System.Diagnostics.Debugger.Break() End Sub Function myTest(ByVal m As Member) As Boolean Return m.ID = "100" AndAlso m.Roles.Select(AddressOf myRoleTest).Count > 0 End Function Function myRoleTest(ByVal r As Role) As Boolean Return r.Name = "Member" End Function SQL Profiler shows this: SQL:BatchStarting SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] RPC:Completed exec sp_executesql N'SELECT [Extent2].[ID] AS [ID], [Extent2].[Name] AS [Name], [Extent2].[Active] AS [Active] FROM [dbo].[RoleMembership] AS [Extent1] INNER JOIN [dbo].[Roles] AS [Extent2] ON [Extent1].[RoleID] = [Extent2].[ID] WHERE [Extent1].[MemberID] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=100 SQL:BatchCompleted SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] I'm not certain why it is using sp_execsql for the inner join statement and why it's still running a select to select ALL members though. Thanks. UPDATE 2 I've written it by turning the above "multiple methods" into lambda expressions then all into one query, like this: Dim allIDs As String = String.Empty Using dc As New CBLModel.CBLEntities For Each retM In dc.Members.Where(Function(m As Member) m.ID = 100 AndAlso m.Roles.Select(Function(r As Role) r.Name = "Doctor").Count > 0) allIDs &= retM.ID.ToString & ";" Next End Using But it doesn't seem to work: "Doctor" is not a role that exists, I just put it in there for testing purposes, yet "allIDs" still gets set to "100;" The SQL in SQL Profiler this time looks like this: SELECT [Project1].* FROM ( SELECT [Extent1].*, (SELECT COUNT(1) AS [A1] FROM [dbo].[RoleMembership] AS [Extent2] WHERE [Extent1].[ID] = [Extent2].[MemberID]) AS [C1] FROM [dbo].[Members] AS [Extent1] ) AS [Project1] WHERE (100 = [Project1].[ID]) AND ([Project1].[C1] > 0) For brevity I turned the list of all the columns from the Members table into * As you can see it's just ignoring the "Role" query... :/

So is there a way to make it so that I can get the values A-Z and 0-9 in the other cells I specified above? Thank you.

• How to remove the xmlns:XSI and xmlns:XSD namespaces from the xml output of a webservice in .net fra

  - by Chetan

  HI, This is an old question, i have seen some solutions on this forum itself, but am trying to use webservices for the first time so please bear with me on this one. I have a webservice that returns XML in the following format <subs xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" msisdn="965xxxxxx"> <shortcode label="XXXX"> <channels> <channel> <id>442</id> <name>News</name> <billingperiod>7</billingperiod> <billingamount>3</billingamount> <lastbilling>4/14/2010 1:41:11 PM</lastbilling> </channel> <channel> <id>443</id> <name>News2</name> <billingperiod>7</billingperiod> <billingamount>3</billingamount> <lastbilling>4/14/2010 1:41:19 PM</lastbilling> </channel> </channels> </shortcode> </subs> I want the same XMl output without the xmlns:xsd and xmlns:xsi tags. I have tried the following solution that was suggested: Public Function GetSubscription(....) As String Dim namespaces As New XmlSerializerNamespaces namespaces.Add(String.Empty, String.Empty) Dim serializer As New XmlSerializer(SubsDetail.GetType) Dim sw As New System.IO.StringWriter Dim writer As New System.Xml.XmlTextWriter(sw) writer.Formatting = Formatting.None serializer.Serialize(writer, SubsDetail, namespaces) writer.Close() Return sw.toString() The result was that I got an xml in the following format: <string> <?xml version="1.0" encoding="utf-16"?><subs msisdn="965xxxx"> <shortcode label="XXXX"> <channels> <channel> <id>442</id> <name>News</name> <billingperiod>7</billingperiod> <billingamount>3</billingamount> <lastbilling>4/14/2010 1:41:11 PM</lastbilling> </channel> <channel> <id>443</id> <name>News2</name> <billingperiod>7</billingperiod> <billingamount>3</billingamount> <lastbilling>4/14/2010 1:41:19 PM</lastbilling> </channel> </channels> </shortcode> </subs> </string> Though the format of the xml is correct it is coming as string within the <string> tags. This is really driving me nuts. Can I get the output as xml without the outer string tags?

• WPF ListView as a DataGrid – Part 2

  - by psheriff

  In my last blog post I showed you how to create GridViewColumn objects on the fly from the meta-data in a DataTable. By doing this you can create columns for a ListView at runtime instead of having to pre-define each ListView for each different DataTable. Well, many of us use collections of our classes and it would be nice to be able to do the same thing for our collection classes as well. This blog post will show you one approach for using collection classes as the source of the data for your ListView.  Figure 1: A List of Data using a ListView Load Property NamesYou could use reflection to gather the property names in your class, however there are two things wrong with this approach. First, reflection is too slow, and second you may not want to display all your properties from your class in the ListView. Instead of reflection you could just create your own custom collection class of PropertyHeader objects. Each PropertyHeader object will contain a property name and a header text value at a minimum. You could add a width property if you wanted as well. All you need to do is to create a collection of property header objects where each object represents one column in your ListView. Below is a simple example: PropertyHeaders coll = new PropertyHeaders(); coll.Add(new PropertyHeader("ProductId", "Product ID"));coll.Add(new PropertyHeader("ProductName", "Product Name"));coll.Add(new PropertyHeader("Price", "Price")); Once you have this collection created, you could pass this collection to a method that would create the GridViewColumn objects based on the information in this collection. Below is the full code for the PropertyHeader class. Besides the PropertyName and Header properties, there is a constructor that will allow you to set both properties when the object is created. C#public class PropertyHeader{  public PropertyHeader()  {  }   public PropertyHeader(string propertyName, string headerText)  {    PropertyName = propertyName;    HeaderText = headerText;  }   public string PropertyName { get; set; }  public string HeaderText { get; set; }} VB.NETPublic Class PropertyHeader  Public Sub New()  End Sub   Public Sub New(ByVal propName As String, ByVal header As String)    PropertyName = propName    HeaderText = header  End Sub   Private mPropertyName As String  Private mHeaderText As String   Public Property PropertyName() As String    Get      Return mPropertyName    End Get    Set(ByVal value As String)      mPropertyName = value    End Set  End Property   Public Property HeaderText() As String    Get      Return mHeaderText    End Get    Set(ByVal value As String)      mHeaderText = value    End Set  End PropertyEnd Class You can use a Generic List class to create a collection of PropertyHeader objects as shown in the following code. C#public class PropertyHeaders : List<PropertyHeader>{} VB.NETPublic Class PropertyHeaders  Inherits List(Of PropertyHeader)End Class Create Property Header Objects You need to create a method somewhere that will create and return a collection of PropertyHeader objects that will represent the columns you wish to add to your ListView prior to binding your collection class to that ListView. Below is a sample method called GetProperties that builds a list of PropertyHeader objects with properties and headers for a Product object. C#public PropertyHeaders GetProperties(){  PropertyHeaders coll = new PropertyHeaders();   coll.Add(new PropertyHeader("ProductId", "Product ID"));  coll.Add(new PropertyHeader("ProductName", "Product Name"));  coll.Add(new PropertyHeader("Price", "Price"));   return coll;} VB.NETPublic Function GetProperties() As PropertyHeaders  Dim coll As New PropertyHeaders()   coll.Add(New PropertyHeader("ProductId", "Product ID"))  coll.Add(New PropertyHeader("ProductName", "Product Name"))  coll.Add(New PropertyHeader("Price", "Price"))   Return collEnd Function WPFListViewCommon Class Now that you have a collection of PropertyHeader objects you need a method that will create a GridView and a collection of GridViewColumn objects based on this PropertyHeader collection. Below is a static/Shared method that you might put into a class called WPFListViewCommon. C#public static GridView CreateGridViewColumns(  PropertyHeaders properties){  GridView gv;  GridViewColumn gvc;   // Create the GridView  gv = new GridView();  gv.AllowsColumnReorder = true;   // Create the GridView Columns  foreach (PropertyHeader item in properties)  {    gvc = new GridViewColumn();    gvc.DisplayMemberBinding = new Binding(item.PropertyName);    gvc.Header = item.HeaderText;    gvc.Width = Double.NaN;    gv.Columns.Add(gvc);  }   return gv;} VB.NETPublic Shared Function CreateGridViewColumns( _    ByVal properties As PropertyHeaders) As GridView  Dim gv As GridView  Dim gvc As GridViewColumn   ' Create the GridView  gv = New GridView()  gv.AllowsColumnReorder = True   ' Create the GridView Columns  For Each item As PropertyHeader In properties    gvc = New GridViewColumn()    gvc.DisplayMemberBinding = New Binding(item.PropertyName)    gvc.Header = item.HeaderText    gvc.Width = [Double].NaN    gv.Columns.Add(gvc)  Next   Return gvEnd Function Build the Product Screen To build the window shown in Figure 1, you might write code like the following: C#private void CollectionSample(){  Product prod = new Product();   // Setup the GridView Columns  lstData.View = WPFListViewCommon.CreateGridViewColumns(       prod.GetProperties());  lstData.DataContext = prod.GetProducts();} VB.NETPrivate Sub CollectionSample()  Dim prod As New Product()   ' Setup the GridView Columns  lstData.View = WPFListViewCommon.CreateGridViewColumns( _       prod.GetProperties())  lstData.DataContext = prod.GetProducts()End Sub The Product class contains a method called GetProperties that returns a PropertyHeaders collection. You pass this collection to the WPFListViewCommon’s CreateGridViewColumns method and it will create a GridView for the ListView. When you then feed the DataContext property of the ListView the Product collection the appropriate columns have already been created and data bound. Summary In this blog you learned how to create a ListView that acts like a DataGrid using a collection class. While it does take a little code to do this, it is an alternative to creating each GridViewColumn in XAML. This gives you a lot of flexibility. You could even read in the property names and header text from an XML file for a truly configurable ListView. NOTE: You can download the complete sample code (in both VB and C#) at my website. http://www.pdsa.com/downloads. Choose Tips & Tricks, then "WPF ListView as a DataGrid – Part 2" from the drop-down.

• .NET Properties - Use Private Set or ReadOnly Property?

  - by tgxiii

  In what situation should I use a Private Set on a property versus making it a ReadOnly property? Take into consideration the two very simplistic examples below. First example: Public Class Person Private _name As String Public Property Name As String Get Return _name End Get Private Set(ByVal value As String) _name = value End Set End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo Me.Name = txtInfo.ToTitleCase(Me.Name) End Sub End Class // ---------- public class Person { private string _name; public string Name { get { return _name; } private set { _name = value; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; this.Name = txtInfo.ToTitleCase(this.Name); } } Second example: Public Class AnotherPerson Private _name As String Public ReadOnly Property Name As String Get Return _name End Get End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo _name = txtInfo.ToTitleCase(_name) End Sub End Class // --------------- public class AnotherPerson { private string _name; public string Name { get { return _name; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; _name = txtInfo.ToTitleCase(_name); } } They both yield the same results. Is this a situation where there's no right and wrong, and it's just a matter of preference?

  I just realized that I can access shared members from instances of classes (probably this is not correct, but compile and run), and also learn/discover that, I can modify shared members, then create a new instance and access the new value of the shared member. My question is, what happens to the shared members, when it comes back to the "default" value (class declaration), how dangerous is it do this ? is it totally bad ? is it valid in some cases ?. If you want to test my point here is the code (console project vb.net) that I used to test shared members, as you can see/compile/run, the shared member "x" of the class "Hello" has default value string "Default", but at runtime it changes it, and after creating a new object of that class, this object has the new value of the shared member. Module Module1 Public Class hello Public Shared x As String = "Default" Public Sub New() End Sub End Class Sub Main() Console.WriteLine("hello.x=" & hello.x) Dim obj As New hello() Console.WriteLine("obj.x=" & obj.x) obj.x = "Default shared memeber, modified in object" Console.WriteLine("obj.x=" & obj.x) hello.x = "Defaul shared member, modified in class" Console.WriteLine("hello.x=" & hello.x) Dim obj2 As New hello() Console.WriteLine("obj2.x=" & obj2.x) Console.ReadLine() End Sub End Module UPDATE: First at all, thanks to everyone, each answer give feedback, I suppose, by respect I should choose one as "the answer", I don't want to be offensive to anyone, so please don't take it so bad if I didn't choose you answer.

• Font serialization in vb.net

  - by jovany

  Hello all, as the title says , I need to serialize my font. I have tried the following approach unfortunately to no avail. This is what I have and what happens; I have a drawing application and certain variables and properties need to be serialized. (So , Xml.Serialization has been used.) Now this has already been done in a huge portion and I've created some other attributes which needed to be serialized and it works. There is one base class and classes such as drawablestar, drawableeclipse ,etc. all inherit from this class. As does my drawabletextboxclass. The base class is Serializable as can be seen in the sample below. It looks like this... Imports System.Xml.Serialization <Serializable()> _ Public MustInherit Class Drawable ' Drawing characteristics. 'Font characteristics <XmlIgnore()> Public FontFamily As String <XmlIgnore()> Public FontSize As Integer <XmlIgnore()> Public FontType As Integer <XmlIgnore()> Public ForeColor As Color <XmlIgnore()> Public FillColor As Color <XmlAttributeAttribute()> Public LineWidth As Integer = 0 <XmlAttributeAttribute()> Public X1 As Integer <XmlAttributeAttribute()> Public Y1 As Integer <XmlAttributeAttribute()> Public X2 As Integer <XmlAttributeAttribute()> Public Y2 As Integer ' attributes for size textbox <XmlAttributeAttribute()> Public widthLabel As Integer <XmlAttributeAttribute()> Public heightLabel As Integer '<XmlTextAttribute()> Public FontFamily As String '<XmlAttributeAttribute()> Public FontSize As Integer 'this should actually not be here.. <XmlAttributeAttribute()> Public s_InsertLabel As String ' Indicates whether we should draw as selected. <XmlIgnore()> Public IsSelected As Boolean = False ' Constructors. Public Sub New() ForeColor = Color.Black FillColor = Color.White 'FontFamily = "Impact" 'FontSize = 12 End Sub Friend WriteOnly Property _Label() As String Set(ByVal Value As String) s_InsertLabel = Value End Set End Property Public Sub New(ByVal fore_color As Color, ByVal fill_color As Color, Optional ByVal line_width As Integer = 0) LineWidth = line_width ForeColor = fore_color FillColor = fill_color ' FontFamily = Font_Family ' FontSize = Font_Size End Sub ' Property procedures to serialize and ' deserialize ForeColor and FillColor. <XmlAttributeAttribute("ForeColor")> _ Public Property ForeColorArgb() As Integer Get Return ForeColor.ToArgb() End Get Set(ByVal Value As Integer) ForeColor = Color.FromArgb(Value) End Set End Property <XmlAttributeAttribute("BackColor")> _ Public Property FillColorArgb() As Integer Get Return FillColor.ToArgb() End Get Set(ByVal Value As Integer) FillColor = Color.FromArgb(Value) End Set End Property 'Property procedures to serialize and 'deserialize Font <XmlAttributeAttribute("InsertLabel")> _ Public Property InsertLabel_() As String Get Return s_InsertLabel End Get Set(ByVal value As String) s_InsertLabel = value End Set End Property <XmlAttributeAttribute("FontSize")> _ Public Property FontSizeGet() As Integer Get Return FontSize End Get Set(ByVal value As Integer) FontSize = value End Set End Property <XmlAttributeAttribute("FontFamily")> _ Public Property FontFamilyGet() As String Get Return FontFamily End Get Set(ByVal value As String) FontFamily = value End Set End Property <XmlAttributeAttribute("FontType")> _ Public Property FontType_() As Integer Get Return FontType End Get Set(ByVal value As Integer) FontType = value End Set End Property #Region "Methods to override" Public MustOverride Sub Draw(ByVal gr As Graphics) ' Return the object's bounding rectangle.

Public Overrides Function IsEmpty() As Boolean Return (X1 = X2) AndAlso (Y1 = Y2) End Function End Class The coordinates ( X1 ,X2,Y1, Y2 ) are needed to draw a circle , rectangle etc. ( in the other classes ).This all works. If I load my saved file it shows me the correct location and correct size of drawn objects. If I open my xml file I can see all values are correctly saved ( including my FontFamily ). Also the color which can be adjusted is saved and then properly displayed when I load a previously saved drawing. Of course because the coordinates work, if I insert a textField ,the location where it is being displayed is correct. However here comes the problem , my fontSize and fontfamily don't work. As you can see I created them in the base class, However this does not work. Is my approach completely off? What can I do ? Before saving img14.imageshack.us/i/beforeos.jpg/ After loading the Font jumps back to Sans serif and size 12. I could really use some help here.. Edit: I've been using the sample from this website http://www.vb-helper.com/howto_net_drawing_framework.html

• Knowing your user is key--Part 1: Motivation

  - by erikanollwebb

  I was thinking where the best place to start in this blog would be and finally came back to a theme that I think is pretty critical--successful gamification in the enterprise comes down to knowing your user.  Lots of folks will say that gamification is about understanding that everyone is a gamer.  But at least in my org, that argument won't play for a lot of people.  Pun intentional.  It's not that I don't see the attraction to the idea--really, very few people play no games at all.  If they don't play video games, they might play solitaire on their computer.  They may play card games, or some type of sport.  Mario Herger has some great facts on how much game playing there is going on at his Enterprise-Gamification.com website. But at the end of the day, I can't sell that into my organization well.  We are Oracle.  We make big, serious software designed run your whole business.  We don't make Angry Birds out of your financial reporting tools.  So I stick with the argument that works better.  Gamification techniques are really just good principals of user experience packaged a little differently.  Feedback?  We already know feedback is important when using software.  Progress indicators?  Got that too.  Game mechanics may package things in a more explicit way but it's not really "new".  To know how to use game mechanics, and what a user experience team is important for, is totally understanding who our users are and what they are motivated by. For several years, I taught college psychology courses, including Motivation.  Motivation is generally broken down into intrinsic and extrinsic motivation.  There's intrinsic, which comes from within the individual.  And there's extrinsic, which comes from outside the individual.  Intrinsic motivation is that motivation that comes from just a general sense of pleasure in the doing of something.  For example, I like to cook.  I like to cook a lot.  The kind of cooking I think is just fun makes other people--people who don't like to cook--cringe.  Like the cake I made this week--the star-spangled rhapsody from The Cake Bible: two layers of meringue, two layers of genoise flavored with a raspberry eau de vie syrup, whipped cream with berries and a mousseline buttercream, also flavored with raspberry liqueur and topped with fresh raspberries and blueberries. I love cooking--I ask for cooking tools for my birthday and Christmas, I take classes like sushi making and knife skills for fun.  I like reading about you can make an emulsion of egg yolks, melted butter and lemon, cook slowly and transform them into a sauce hollandaise (my use of all the egg yolks that didn't go into the aforementioned cake).  And while it's nice when people like what I cook, I don't do it for that.  I do it because I think it's fun.  My former boss, Ultan Ó Broin, loves to fish in the sea off the coast of Ireland.  Not because he gets prizes for it, or awards, but because it's fun.  To quote a note he sent me today when I asked if having been recently ill kept him from the beginning of mackerel season, he told me he had already been out and said "I can fish when on a deathbed" (read more of Ultan's work, see his blogs on User Assistance and Translation.). That's not the kind of intensity you get about something you don't like to do.  I'm sure you can think of something you do just because you like it. So how does that relate to gamification?  Gamification in the enterprise space is about uncovering the game within work.  Gamification is about tapping into things people already find motivating.  But to do that, you need to know what that user is motivated by. Customer Relationship Management (CRM) is one of those areas where over-the-top gamification seems to work (not to plug a competitor in this space, but you can search on what Bunchball* has done with a company just a little north of us on 101 for the CRM crowd).  Sales people are naturally competitive and thrive on that plus recognition of their sales work.  You can use lots of game mechanics like leaderboards and challenges and scorecards with this type of user and they love it.  Show my whole org I'm leading in sales for the quarter?  Bring it on!  However, take the average accountant and show how much general ledger activity they have done in the last week and expose it to their whole org on a leaderboard and I think you'd see a lot of people looking for a new job.  Why?  Because in general, accountants aren't extraverts who thrive on competition in their work.  That doesn't mean there aren't game mechanics that would work for them, but they won't be the same game mechanics that work for sales people.  It's a different type of user and they are motivated by different things. To break this up, I'll stop here and post now.  I'll pick this thread up in the next post. Thoughts? Questions? *Disclosure: To my knowledge, Oracle has no relationship with Bunchball at this point in time.

• Wiped data, and duplicated folders into files.

  - by Kaustubh P

  Something weird happened today, and I dont know how. Within a folder, all folders have a file by the same name, with a colon appended to it. And all the files from the most inner-most directory in my home, have been dumped to ~, with a size of 0 bytes. I have not executed any scripts or anything. I was just checking out some easter eggs, namely the gegls from outer space and free the fish and was away from the computer and was logged because of the screensaver. I couldnt log-back in with my password, so I just reset the PC, and while booting, the PC went into a drive check. BUT, IIRC, i saw the duplicate "folder files" before I had logged out, so thats not the reason! All the files have a timestamp of 14 Jan. Also, the contents of my eclipse folder have been dumped into ~. Right down to the jars and ini files. HELP!

• Techniques and methods to improve and speedup development

  - by Jlouro

  I just got a new project. It’s a WinForm app. And it’s interesting because I will have the possibility to learn how fish farms work and are managed. I will have to develop touch interfaces, and use datasnap to communicate and sync data between farm and office. The development will be done in DELPHI win32, still not sure about the database, but maybe SQLlite. So now comes the difficult part of the project, building it. I am just finishing one. It took me a lot of time to do it and I am a bit “burned out”. I will have time to relax, not much, but a few days. What I am looking is some tips and tricks and possibly tools to be able to speed up the development. It must be up and running in 2 months. So what tricks do you use to speed up things?

• File manager (Nautilus) hangs or is ultra slow when listing contents of ssh/sftp server

  - by NahsiN

  I used to use File -- Connect to server to connect to my remote ssh a lot before 12.04/11.10. But now in a fresh install of 12.04, whenever I try to access the remote files, nautilus either always hangs or is ultra slow (5 mins) in listing the directory contents. Most of the time I have to force quit or xkill. Mounting using SSHFS works fine. The ssh server is fast and it works fine via putty, mc (using fish) and normal terminal. I also installed nautilus in Lubuntu 12.04 (virtualbox) and to my surprise, browsing is fast and smooth. Both versions of nautilus are at 3.4.2 thus I am led to believe the problem might be lying somewhere in Ubuntu 12.04. But I am clueless. All suggestions welcome. I really need to solve this problem.

• How will this affect my SEO ranking?

  - by dunc

  I run a fishkeeping website based on a WordPress (PHP) CMS. I've recently put a fairly complex "filter" into place which searches my content for mentions of fish species profiles and turns them into an active link. For example, asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and A. panduro and Apistogramma panduro ...becomes asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and <a href="/?p=1703" class="link_species">A. panduro</a> and <a href="/?p=1703" class="link_species">Apistogramma panduro</a> On the rest of my website, the species are linked with pretty URLs such as /species/apistogramma-panduro/ but due to the way this filter works, the only information I can get access to is the idof the post. As such, I'm using /?p=1703 or whatever the ID is. What I'd like to know is: how much will this affect my SEO rating/ranking? Will it be detrimental if I don't rewrite the function? Thanks in advance,

• iTextSharp custom paper size

  - by Morron

  Hi, I'm using iTextsharp library to create PDF files. I can declare for A4 Landscape paper like this: Dim pdfTable As New PdfPTable(9) pdfTable.WidthPercentage = 100 Dim pdfDoc As New Document(PageSize.A4.Rotate()) I'm wondering how I can set Height of pdfTable or A4 Height manually. Because there's a lot more margin left at the bottom, and I need to put some text at that margin. Right now, I put a line of text at the bottom, the line's got pushed to the new page. Q1: How can I override the height of A4 paper provied by iTextsharp? Q2: How can I create a custom size paper, say Width = 29cm, Height = 22cm? Thank you.
