• How to map different UI views in a RESTful web application?

  - by MicE

  Hello, I'm designing a web application, which will support both standard UIs (accessed via browsers) and a RESTful API (an XML/JSON-based web service). User agents will be able to differentiate between these by using different values in the Accept HTTP header. The RESTful API will use the following URI structure (example for an "article" resource): GET /article/ - gets a list of articles POST /article/ - adds a new article PUT /article/{id} - updates an existing article based on {id} DELETE /article/{id} - deletes an existing article based on {id} The UI part of the application will however need to support multiple views, for example: a standard resource view a view for submitting a new resource a view for editing an existing resource a view for deleting an existing resource (i.e. display delete confirmation) Note that the latter three views are still accessed via GET, even though they are processed via overloaded POST. Possible solution: Introduce additional parameters (keywords) into URIs which would identify individual views - i.e. on top of the above, the application would support the following URIs (but only for Content-Type: text/html): GET /article/add - displays a form for adding a new article (fetched via GET, processed via POST) GET /article/123 - displays article 123 in "view" mode (fetched via GET) GET /article/123/edit - displays article 123 in "edit" mode (fetched via GET, processed via PUT overloaded as POST) GET /article/123/delete - displays "delete" confirmation for article 123 (fetched via GET, processed via DELETE overloaded as POST) A better implementation of the above might be to put the add/edit/delete keywords into a GET parameter - since they do not change the resource we're working with, it might be better to keep the base URI same for all of them. My question is: How would you map the above URI structure to UIs served to the regular user, considering that there can be several views per each resource, please? Do you agree with the possible solution detailed above, or would you recommend a different approach based on your experience? NB: we've already implemented an application which consists of a standalone RESTful API and a standalone web application. I'm currently looking into options for future projects where these two would be merged together (i.e. in order to reduce overhead). Thank you, M.

• How to avoid loading a LINQ to SQL object twice when editting it on a website.

  - by emzero

  Hi guys I know you are all tired of this Linq-to-Sql questions, but I'm barely starting to use it (never used an ORM before) and I've already find some "ugly" things. I'm pretty used to ASP.NET Webforms old school developing, but I want to leave that behind and learn the new stuff (I've just started to read a ASP.NET MVC book and a .NET 3.5/4.0 one). So here's is one thing I didn't like and I couldn't find a good alternative to it. In most examples of editing a LINQ object I've seen the object is loaded (hitting the db) at first to fill the current values on the form page. Then, the user modify some fields and when the "Save" button is clicked, the object is loaded for second time and then updated. Here's a simplified example of ScottGu NerdDinner site. // // GET: /Dinners/Edit/5 [Authorize] public ActionResult Edit(int id) { Dinner dinner = dinnerRepository.GetDinner(id); return View(new DinnerFormViewModel(dinner)); } // // POST: /Dinners/Edit/5 [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Edit(int id, FormCollection collection) { Dinner dinner = dinnerRepository.GetDinner(id); UpdateModel(dinner); dinnerRepository.Save(); return RedirectToAction("Details", new { id=dinner.DinnerID }); } As you can see the dinner object is loaded two times for every modification. Unless I'm missing something about LINQ to SQL caching the last queried objects or something like that I don't like getting it twice when it should be retrieved only one time, modified and then comitted back to the database. So again, am I really missing something? Or is it really hitting the database twice (in the example above it won't harm, but there could be cases that getting an object or set of objects could be heavy stuff). If so, what alternative do you think is the best to avoid double-loading the object? Thank you so much, Greetings!

• Procedure or function AppendDataCT has too many arguments specified

  - by salvationishere

  I am developing a C# VS 2008 / SQL Server website application. I am a newbie to ASP.NET. I am getting the above compiler error. Can you give me advice on how to fix this? Code snippet: public static string AppendDataCT(DataTable dt, Dictionary<int, string> dic) { string connString = ConfigurationManager.ConnectionStrings["AW3_string"].ConnectionString; string errorMsg; try { SqlConnection conn2 = new SqlConnection(connString); SqlCommand cmd = conn2.CreateCommand(); cmd.CommandText = "dbo.AppendDataCT"; cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = conn2; SqlParameter p1, p2, p3; foreach (string s in dt.Rows[1].ItemArray) { DataRow dr = dt.Rows[1]; // second row p1 = cmd.Parameters.AddWithValue((string)dic[0], (string)dr[0]); p1.SqlDbType = SqlDbType.VarChar; p2 = cmd.Parameters.AddWithValue((string)dic[1], (string)dr[1]); p2.SqlDbType = SqlDbType.VarChar; p3 = cmd.Parameters.AddWithValue((string)dic[2], (string)dr[2]); p3.SqlDbType = SqlDbType.VarChar; } conn2.Open(); cmd.ExecuteNonQuery(); It errors on this last line here.

• tangent of two circles

  - by harryovers

  Hello, I am trying to write some code that that will draw the line which is a tangent between 2 circles. so far i have been able to draw multiple circles, and lines between the centers. i have a class which stores the values used in drawing the circles (radius, position). what i need is a method in this class to find all posible tangents between 2 circles. any help would be great. this is what i have so far (it could very well be a load of rubbish) public static Vector2[] Tangents(circle c1, circle c2) { if (c2.radius > c1.radius) { circle temp = c1; c1 = c2; c2 = temp; } circle c0 = new circle(c1.radius - c2.radius, c1.center); Vector2[] tans = new Vector2[2]; Vector2 dir = _point - _center; float len = (float)Math.Sqrt((dir.X * dir.X) + (dir.Y * dir.Y)); float angle = (float)Math.Atan2(dir.X, dir.Y); float tan_length = (float)Math.Sqrt((len * len) - (_radius * _radius)); float tan_angle = (float)Math.Asin(_radius / len); tans[0] = new Vector2((float)Math.Cos(angle + tan_angle), (float)Math.Sin(angle + tan_angle)); tans[1] = new Vector2((float)Math.Cos(angle - tan_angle), (float)Math.Sin(angle - tan_angle)); Vector2 dir0 = c0.center - tans[0]; Vector2 dir1 = c0.center - tans[1]; Vector2 tan00 = Vector2.Add(Vector2.Multiply(tans[0], (float)c2.radius), c1.center); Vector2 tan01 = c2.center; Vector2 tan10 = Vector2.Add(Vector2.Multiply(tans[1], (float)c2.radius), c1.center); Vector2 tan11 = c2.center; }

• Extension Method for copying properties form object to another, with first attempt

  - by James

  Hi All, Im trying to write an extension method that I can use to copy values from one object property to another object of a different type, as long as the property names and types match exactly. This is what I have: public static T CopyFrom<T>(this T toObject, object fromObject) { var fromObjectType = fromObject.GetType(); var fromProperties = fromObjectType.GetProperties(); foreach (PropertyInfo toProperty in toObject.GetType().GetProperties()) { PropertyInfo fromProperty = fromObjectType.GetProperty(toProperty.Name); if (fromProperty != null) // match found { // check types var fromType = fromProperty.PropertyType.UnderlyingSystemType; var toType = toProperty.PropertyType.UnderlyingSystemType; if (toType.IsAssignableFrom(fromType)) { toProperty.SetValue(toObject, fromProperty.GetValue(fromObject, null), null); } } } return toObject; } This is working great for non boxed types, but Nullable<T> returns false when I call toType.IsAssignableFrom(fromType) because its type is Nullable<T> and is not the underlying type T. I read here that GetType() should unbox the Nullable<T> so it returns T but if I call that on PropertyInfo.PropertyType I get ReflectedMemberInfo and not the type T im looking for. I think im missing something obvious here, so I thought I would throw it open to SO to get some advice. Anyone have any ideas? Thanks, Jamee

• split string error in a compiled VB.NET class

  - by Andy Payne

  I'm having some trouble compiling some VB code I wrote to split a string based on a set of predefined delimeters (comma, semicolon, colon, etc). I have successfully written some code that can be loaded inside a custom VB component (I place this code inside a VB.NET component in a plug-in called Grasshopper) and everything works fine. For instance, let's say my incoming string is "123,456". When I feed this string into the VB code I wrote, I get a new list where the first value is "123" and the second value is "456". However, I have been trying to compile this code into it's own class so I can load it inside Grasshopper separately from the standard VB component. When I try to compile this code, it isn't separating the string into a new list with two values. Instead, I get a message that says "System.String []". Do you guys see anything wrong in my compile code? You can find an screenshot image of my problem at the following link: click to see image This is the VB code for the compiled class: Public Class SplitString Inherits GH_Component Public Sub New() MyBase.New("Split String", "Split", "Splits a string based on delimeters", "FireFly", "Serial") End Sub Public Overrides ReadOnly Property ComponentGuid() As System.Guid Get Return New Guid("3205caae-03a8-409d-8778-6b0f8971df52") End Get End Property Protected Overrides ReadOnly Property Internal_Icon_24x24() As System.Drawing.Bitmap Get Return My.Resources.icon_splitstring End Get End Property Protected Overrides Sub RegisterInputParams(ByVal pManager As Grasshopper.Kernel.GH_Component.GH_InputParamManager) pManager.Register_StringParam("String", "S", "Incoming string separated by a delimeter like a comma, semi-colon, colon, or forward slash", False) End Sub Protected Overrides Sub RegisterOutputParams(ByVal pManager As Grasshopper.Kernel.GH_Component.GH_OutputParamManager) pManager.Register_StringParam("Tokenized Output", "O", "Tokenized Output") End Sub Protected Overrides Sub SolveInstance(ByVal DA As Grasshopper.Kernel.IGH_DataAccess) Dim myString As String DA.GetData(0, myString) myString = myString.Replace(",", "|") myString = myString.Replace(":", "|") myString = myString.Replace(";", "|") myString = myString.Replace("/", "|") myString = myString.Replace(")(", "|") myString = myString.Replace("(", String.Empty) myString = myString.Replace(")", String.Empty) Dim parts As String() = myString.Split("|"c) DA.SetData(0, parts) End Sub End Class This is the custom VB code I created inside Grasshopper: Private Sub RunScript(ByVal myString As String, ByRef A As Object) myString = myString.Replace(",", "|") myString = myString.Replace(":", "|") myString = myString.Replace(";", "|") myString = myString.Replace("/", "|") myString = myString.Replace(")(", "|") myString = myString.Replace("(", String.Empty) myString = myString.Replace(")", String.Empty) Dim parts As String() = myString.Split("|"c) A = parts End Sub ' ' End Class

• Instead of trigger in SQL Server - looses SCOPE_IDENTITY?

  - by kastermester

  Hey StackOverflow, I am (once again) having some issues with some SQL. I have a table, on which I have created an INSTEAD OF trigger to enforce some buissness rules (rules not really important). This works as intended. My issue is, that now when inserting data into this table, SCOPE_IDENTITY() now returns a NULL value, rather than the actual inserted identity, my guess is that this is because it is now out of scope - but then how do I get this in scope? I am using SQL Server 2008. Per request, here's the SQL: Insert + Scope code INSERT INTO [dbo].[Payment]([DateFrom], [DateTo], [CustomerId], [AdminId]) VALUES ('2009-01-20', '2009-01-31', 6, 1) SELECT SCOPE_IDENTITY() Trigger: CREATE TRIGGER [dbo].[TR_Payments_Insert] ON [dbo].[Payment] INSTEAD OF INSERT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; IF NOT EXISTS(SELECT 1 FROM dbo.Payment p INNER JOIN Inserted i ON p.CustomerId = i.CustomerId WHERE (i.DateFrom >= p.DateFrom AND i.DateFrom <= p.DateTo) OR (i.DateTo >= p.DateFrom AND i.DateTo <= p.DateTo) ) AND NOT EXISTS (SELECT 1 FROM Inserted p INNER JOIN Inserted i ON p.CustomerId = i.CustomerId WHERE (i.DateFrom <> p.DateFrom AND i.DateTo <> p.DateTo) AND ((i.DateFrom >= p.DateFrom AND i.DateFrom <= p.DateTo) OR (i.DateTo >= p.DateFrom AND i.DateTo <= p.DateTo)) ) BEGIN INSERT INTO dbo.Payment (DateFrom, DateTo, CustomerId, AdminId) SELECT DateFrom, DateTo, CustomerId, AdminId FROM Inserted END ELSE BEGIN ROLLBACK TRANSACTION END END The code did work before the creation of this trigger, also I am using LINQ to SQL in C# and as far as I can see, I have no way of changing SCOPE_IDENTITY to @@IDENITY - is there really no way out of this one?

• Best approach, Dynamic OpenXML in T-SQL

  - by Martin Ongtangco

  hello, i'm storing XML values to an entry in my database. Originally, i extract the xml datatype to my business logic then fill the XML data into a DataSet. I want to improve this process by loading the XML right into the T-SQL. Instead of getting the xml as string then converting it on the BL. My issue is this: each xml entry is dynamic, meaning it can be any column created by the user. I tried using this approach, but it's giving me an error: CREATE PROCEDURE spXMLtoDataSet @id uniqueidentifier, @columns varchar(max) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; DECLARE @name varchar(300); DECLARE @i int; DECLARE @xmlData xml; (SELECT @xmlData = data, @name = name FROM XmlTABLES WHERE (tableID = ISNULL(@id, tableID))); EXEC sp_xml_preparedocument @i OUTPUT, @xmlData DECLARE @tag varchar(1000); SET @tag = '/NewDataSet/' + @name; DECLARE @statement varchar(max) SET @statement = 'SELECT * FROM OpenXML(@i, @tag, 2) WITH (' + @columns + ')'; EXEC (@statement); EXEC sp_xml_removedocument @i END where i pass a dynamically written @columns. For example: spXMLtoDataSet 'bda32dd7-0439-4f97-bc96-50cdacbb1518', 'ID int, TypeOfAccident int, Major bit, Number_of_Persons int, Notes varchar(max)' but it kept on throwing me this exception: Msg 137, Level 15, State 2, Line 1 Must declare the scalar variable "@i". Msg 319, Level 15, State 1, Line 1 Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

• mySQL removes first digit

  - by kielie

  Hi guys, I am inputting data into a mySQL database via a PHP script, but for some reason when I check the database, all of the phone numbers have their first digit removed, like so, 0123456789 shows up as 123456789 in the database, but if I change the data type from INT to TEXT, it shows correctly, I am very hesitant to keep it as TEXT though, as I am sure this will cause complications further down the road as the database app starts to become more complicated, here is the PHP code. <?php $gender = $_POST['gender']; $first_name = $_POST['first_name']; $second_name = $_POST['second_name']; $id_number = $_POST['id_number']; $home_number = $_POST['home_number']; $cell_work = $_POST['cell_work']; $email_address = $_POST['email_address']; $curDate = date("Y-m-d"); mysql_connect ("server", "user", "pass") or die ('Error: ' . mysql_error()); mysql_select_db ("database"); $query = "INSERT INTO table (id,gender,first_name,second_name,id_number,home_number,cell_work,email_address,date) VALUES('NULL','".$gender."','".$first_name."','".$second_name."','".$id_number."','".$home_number."','".$cell_work."','".$email_address."','".$curDate."' )"; mysql_query($query) or die (mysql_error()); ?> Thanx in advance!

• Extracting specific nodes from XML using XML::Twig

  - by pratz

  i was trying to extract a particular set of nodes from the following XML structure using XML::Twig, but have been stuck ever since. I need to extract the 'player' nodes from the following structure and do a string match/replace on each of these node values. <pep:record> <agency> <subrecord type="scout"> <isnum>123XXX (print)</isnum> <isnum>234YYY (mag)</isnum> </subrecord> <subrecord type="group"> </subrecord> </agency </record> I tried using the following code, but I get pointed to a hash reference rather than actual string. my $parser = XML::Twig->new(twig_handlers => { isnum => sub { print $_->text."::" }, }); foreach my $rec (split(/::/, $parser->parse($my_xml))) { if ($rec =~ m/print/) { ($print = $rec) =~ s/( \(print\))//; } elsif($rec =~ m/mag/) { ($mag = $rec) =~ s/( \(mag\))//; } }

• Correct way to trigger object clone/memento when property changes

  - by Jay

  Hi, I have a big doubt about the correct way to save an object state (clone object), if necessary to rollback the changes, when a property has changed. I know that the IEditableObject interface exists for those cases but during some tests the BeginEdit would just fire like crazy (I have a DataGrid whose values can be edited but I won't need to keep the state of the object in these cases). I'm following the MVP design pattern in my project and the view's DataContext is a wrapper of my presenter.Let's say I have a CheckBox/TextBox in my UI and when that textbox's value changes, the property bound in the wrapper gets set.Currently, before setting the new value i'm raising an event to the presenter (something like PropertyChanging) that clones my wrapper. I'm doing this because I don't think that job should be done by the wrapper itself but by the presenter.Is this a correct approach? Raising the event is an acceptable solution? I thought of other possible ideas: Interface between presenter and wrapper; Use explicit binding and trigger the binding after saving object's state; What is your opinion about the best way to do this? Should I just keep IEditableObject, is this the best way? Best Regards

• Python minidom and UTF-8 encoded XML with hash references

  - by Jakob Simon-Gaarde

  Hi I am experiencing some difficulty in my home project where I need to parse a SOAP request. The SOAP is generated with gSOAP and involves string parameters with special characters like the danish letters "æøå". gSOAP builds SOAP requests with UTF-8 encoding by default, but instead of sending the special chatacters in raw format (ie. bytes C3A6 for the special character "æ") it sends what I think is called character hash references (ie. &#195;&#166;). I don't completely understand why gSOAP does it this way as I can see that it has marked the incomming payload as being UTF-8 encoded anyway (Content-Type: text/xml; charset=utf-8), but this is besides the question (I think). Anyway I guess gSOAP probably is obeying transport rules, or what? When I parse the request from gSOAP in python with xml.dom.minidom.parseString() I get element values as unicode objects which is fine, but the character hash references are not decoded as UTF-8 character codes. It unescapes the character hash references, but does not decode the string afterwards. In the end I have a unicode string object with UTF-8 encoding: So if the string "æble" is contained in the XML, it comes like this in the request: "&#195;&#166;ble" After parsing the XML the unicode string in the DOM Text Node's data member looks like this: u'\xc3\xa6ble' I would expect it to look like this: u'\xe6ble' What am I doing wrong? Should I unescape the SOAP XML before parsing it, or is it somewhere else I should be looking for the solution, maybe gSOAP? Thanks in advance. Best regards Jakob Simon-Gaarde

• Am I correctly extracting JPEG binary data from this mysqldump?

  - by Glenn

  I have a very old .sql backup of a vbulletin site that I ran around 8 years ago. I am trying to see the file attachments that are stored in the DB. The script below extracts them all and is verified to be JPEG by hex dumping and checking the SOI (start of image) and EOI (end of image) bytes (FFD8 and FFD9, respectively) according to the JPEG wiki page. But when I try to open them with evince, I get this message "Error interpreting JPEG image file (JPEG datastream contains no image)" What could be going on here? Some background info: sqldump is around 8 years old vbulletin 2.x was the software that stored the info most likely php 4 was used most likely mysql 4.0, possibly even 3.x the column datatype these attachments are stored in is mediumtext My Python 3.1 script: #!/usr/bin/env python3.1 import re trim_l = re.compile(b"""^INSERT INTO attachment VALUES\('\d+', '\d+', '\d+', '(.+)""") trim_r = re.compile(b"""(.+)', '\d+', '\d+'\);$""") extractor = re.compile(b"""^(.*(?:\.jpe?g|\.gif|\.bmp))', '(.+)$""") with open('attachments.sql', 'rb') as fh: for line in fh: data = trim_l.findall(line)[0] data = trim_r.findall(data)[0] data = extractor.findall(data) if data: name, data = data[0] try: filename = 'files/%s' % str(name, 'UTF-8') ah = open(filename, 'wb') ah.write(data) except UnicodeDecodeError: continue finally: ah.close() fh.close() update The JPEG wiki page says FF bytes are section markers, with the next byte indicating the section type. I see some that are not listed in the wiki page (specifically, I see a lot of 5C bytes, so FF5C). But the list is of "common markers" so I'm trying to find a more complete list. Any guidance here would also be appreciated.

• TCL How to read , extract and count the occurent in .txt file (Current Directory)

  - by Passion

  Hi Folks, I am beginner to scripting and vigorously learning TCL for the development of embedded system. I have to Search for the files with only .txt format in the current directory, count the number of cases of each different "Interface # nnnn" string in .txt file, where nnnn is a four or 32 digits max hexadecimal no and o/p of a table of Interface number against occurrence. I am facing implementation issues while writing a script i.e, Unable to implement the data structure like Linked List, Two Dimensional array. I am rewriting a script using multi dimension array (Pass values into the arrays in and out of procedure) in TCL to scan through the every .txt file and search for the the string/regular expression ‘Interface # ’ to count and display the number of occurrences. If someone could help me to complete this part will be much appreciated. Search for only .txt extension files and obtain the size of the file Here is my piece of code for searching a .txt file in present directory set files [glob *.txt] if { [llength $files] > 0 } { puts "Files:" foreach f [lsort $files] { puts " [file size $f] - $f" } } else { puts "(no files)" } I reckon these are all the possible logical steps behind to complete it i) Once searched and find the .txt file then open all .txt files in read only mode ii) Create a array or list using the procedure (proc) Interface number to NULL and Interface count to zero 0 iii) Scan thro the .txt file and search for the string or regular expression "interface # iv) When a match found in .txt file, check the Interface Number and increment the count for the corresponding entry. Else add new element to the Interface Number list v) If there are no files return to the first directory My o/p is like follows Interface Frequency 123f 3 1232 4

• Controls added in the designer are null during Page_Load

  - by mwright

  All of the names below are generic and not the actual names used. I have a custom UserControl with a Panel that contains a a couple Labels, both .aspx controls. .aspx: <asp:Panel runat="server"> <asp:Label ID="label1" runat="server"> </asp:Label> </asp:Panel> <asp:Panel runat="server"> <asp:Label ID="label2" runat="server"> </asp:Label> </asp:Panel> Codebehind: private readonly Object object; protected void Page_Load(object sender, EventArgs e) { // These are the lines that are failing // label1 and label2 are null label1.Text = object.Value1; label2.Text = object.Value2; } public ObjectRow(Object objectToDisplay) { object = objectToDisplay; } On another page, in the code behind, I create a new instance of the custom user control. protected void Page_Load(object sender, EventArgs e) { CustomControl control = new CustomControl(object); } The user control takes the parameter and attempts to set the labels based off of the object passed in. The labels that it tries to assign the values to are however, null. Is this an ASP.net lifecycle issue that I'm not understanding? My understanding based on the Microsoft ASP.net lifecycle page was that page controls were available after the Page_Initialization. What is the proper way to do this? Is there a better way?

• Flash CS5- Problem with "navigateToURL" in web-browswer hosted on MySpace

  - by NervXT

  I made a quick flash document for my friend who posted it his MySpace. The document has 3 buttons, each with a URL attached to them. When I play the SWF file locally, the links work fine, however once it's published to MySpace, the links refuse to work. The hand icon comes up so it understands them at least as buttons, but it seems to do nothing when clicked in the web-browser. Also, I can open the SWF in my browser and it also works fine. I'm using Flash CS5 and working in ActionScript 3.0. The three buttons are on one layer called "Buttons". I right click the button and click "Actions". From there, I click the "Code Snippets" and under the folder "Actions" there is an item called "Click to Go To Webpage". Here is the code it gives you by default: button_2.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage_6); function fl_ClickToGoToWebPage_6(event:MouseEvent):void { navigateToURL(new URLRequest("http://www.adobe.com"), "_blank"); } I heard there was a problem with MySpace not allowing action scripts, but after checking the source code of the web-page, the values in the "param" code seem to "always" allow action scripts. At any point, I'm lost and not sure what it causing this. I don't think it's a browser issue, since it's working fine when I execute the SWF by itself, and when I load it into Firefox. It's just seems MySpace is having a problem with it. Any advice is appreciated.

• GLSL shader render to texture not saving alpha value

  - by quadelirus

  I am rendering to a texture using a GLSL shader and then sending that texture as input to a second shader. For the first texture I am using RGB channels to send color data to the second GLSL shader, but I want to use the alpha channel to send a floating point number that the second shader will use as part of its program. The problem is that when I read the texture in the second shader the alpha value is always 1.0. I tested this in the following way: at the end of the first shader I did this: gl_FragColor(r, g, b, 0.1); and then in the second texture I read the value of the first texture using something along the lines of vec4 f = texture2D(previous_tex, pos); if (f.a != 1.0) { gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0); return; } No pixels in my output are black, whereas if I change the above code to read gl_FragColor(r, g, 0.1, 1.0); //Notice I'm now sending 0.1 for blue and in the second shader vec4 f = texture2D(previous_tex, pos); if (f.b != 1.0) { gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0); return; } All the appropriate pixels are black. This means that for some reason when I set the alpha value to something other than 1.0 in the first shader and render to a texture, it is still seen as being 1.0 by the second shader. Before I render to texture I glDisable(GL_BLEND); It seems pretty clear to me that the problem has to do with OpenGL handling alpha values in some way that isn't obvious to me since I can use the blue channel in the way I want, and figured someone out there will instantly see the problem.

• fullcalendar : updating option function callbacks after init

  - by Paul Maneesilasan

  Ok, so I have a problem with setting options whose values are callback functions when I try to set them after plugin initialization. I think this would be a common behavior, to dynamically set event callback after init'ing the calendar. Here is a snipit of code: $(document).ready(function() { $('#calendar').fullCalendar({ editable: false ,events:[{"title":"meeting.title","start":"2010-05-21 15:58:16 UTC"},{"title":"meeting.title","start":"2010-05-24 15:58:16", "url":"http://google.com"}] /* ,eventClick: function(event) { if (event.url) { window.open(event.url); return false; } } */ }); $('#calendar').fullCalendar('options', 'eventClick', function(event) { if (event.url) { window.open(event.url); return false; } }); }); You can see that I have setting the eventClick function as an init option commented out. If I do it that way, it works fine. However if I try to set it after the init, it doesn't work :( Is the some other way to do this? Or am I stuck with having to set the behavior upfront?

• Generate number sequences with LINQ

  I try to write a LINQ statement which returns me all possible combinations of numbers (I need this for a test and I was inspired by this article of Eric Lippert). The method's prototype I call looks like: IEnumerable<Collection<int>> AllSequences( int start, int end, int size ); The rules are: all returned collections have a length of size number values within a collection have to increase every number between start and end should be used So calling the AllSequences( 1, 5, 3 ) should result in 10 collections, each of size 3: 1 2 3 1 2 4 1 2 5 1 3 4 1 3 5 1 4 5 2 3 4 2 3 5 2 4 5 3 4 5 Now, somehow I'd really like to see a pure LINQ solution. I am able to write a non LINQ solution on my own, so please put no effort into a solution without LINQ. My tries so far ended at a point where I have to join a number with the result of a recursive call of my method - something like: return from i in Enumerable.Range( start, end - size + 1 ) select BuildCollection(i, AllSequences( i, end, size -1)); But I can't manage it to implement BuildCollection() on a LINQ base - or even skip this method call. Can you help me here?

• (EXCEL)VBA Spin button which steps through in an sql databases date time

  - by Gulredy

  I have an sql Database table in MySQL which have lots of rows with varied date time values. For example: 2012-08-21 10:10:00 <-- with these date there are around 12 rows 2012-08-21 15:31:00 <-- with these date there are around 5 rows 2012-08-22 11:40:00 <-- with these date there are around 10 rows 2012-08-22 12:17:00 <-- with these date there are around 9 rows 2012-08-22 12:18:00 <-- with these date there are around 7 rows 2012-08-25 07:21:00 <-- with these date there are around 6 rows If the user clicks on the SpinButton1_SpinUp() or SpinButton1_SpinDown() button then it should do the following: The SpinButton1_SpinUp() button should filter out those data from an sql table which is the next after what we are currently on now. Example: We have currently selected: 2012-08-21 15:31:00. The user hits the SpinUp button then the program selects those date from the database, which is the next higher value like this one: 2012-08-22 11:40:00. So the user hits the SpinUp button the data which is selected in the database will change from those with date: 2012-08-21 15:31:00 to those with date: 2012-08-22 11:40:00 The SpinButton1_SpinDown() will do exactly the reverse of the SpinUp button. When the user hits the SpinDown button the data which is selected in the database will change from those with date: 2012-08-21 15:31:00 to those with date 2012-08-21 10:10:00 So I think the date which we are currently on, should be stored in a variable. But on button hit not every bigger or lower data should be selected in the database, only those which are the closest bigger or the closest lower date. How can I do this? I hope I described my problem understandable. My native language is not english, so misunderstandings can occur! Please ask if you don't understand something! Thank you for reading!

• Help with Neuroph neural network

  - by user359708

  For my graduate research I am creating a neural network that trains to recognize images. I am going much more complex than just taking a grid of RGB values, downsampling, and and sending them to the input of the network, like many examples do. I actually use over 100 independently trained neural networks that detect features, such as lines, shading patterns, etc. Much more like the human eye, and it works really well so far! The problem is I have quite a bit of training data. I show it over 100 examples of what a car looks like. Then 100 examples of what a person looks like. Then over 100 of what a dog looks like, etc. This is quite a bit of training data! Currently I am running at about one week to train the network. This is kind of killing my progress, as I need to adjust and retrain. I am using Neuroph, as the low-level neural network API. I am running a dual-quadcore machine(16 cores with hyperthreading), so this should be fast. My processor percent is at only 5%. Are there any tricks on Neuroph performance? Or Java peroformance in general? Suggestions? I am a cognitive psych doctoral student, and I am decent as a programmer, but do not know a great deal about performance programming.

• Technically why is processes in Erlang more efficient than OS threads?

  - by Jonas

  Spawning processes seam to be much more efficient in Erlang than starting new threads using the OS (i.e. by using Java or C). Erlang spawns thousands and millions of processes in a short period of time. I know that they are different since Erlang do per process GC and processes in Erlang are implemented the same way on all platforms which isn't the case with OS threads. But I don't fully understand technically why Erlang processes are so much more efficient and has much smaller memory footprint per process. Both the OS and Erlang VM has to do scheduling, context switches and keep track of the values in the registers and so on... Simply why isn't OS threads implemented in the same way as processes in Erlang? Does it have to support something more? and why does it need a bigger memory footprint? Technically why is processes in Erlang more efficient than OS threads? And why can't threads in the OS be implemented and managed in the same efficient way?

• SDL Tridion Schema Field "List of Links" Options

  - by Alvin Reyes

  I'm looking to create an SDL Tridion schema with a list of repeatable links while avoiding multiple fields per link. Hyperlink In a rich text field I have the following options for creating a hyperlink:* Component Anchor http:// mailto: Other When content authors create one of these hyperlinks, they have the option to select linked (visible) text as well as title and target attributes that function like typical HTML hyperlinks. "Richtext" means a Text field with Height of the Text Area = at least 2 rows with Allow Rich Text Formatting selected. Single Schema Field Link When creating a single schema field, I see these options: External Link (author options will include http://, mailto, Other) Multimedia Link Component Link (which can allow Multimedia Values) Current Ideas The best out-of-the-box (OOTB) setups I've found for this "list of links" is either offering: a single 2-line RTF with instructions to create a hyperlink (of any type) in that field separate fields for each type as well as additional fields for display name, target, and title (where the fields are assembled through template code), authors fill in only one of the fields (component link or external) Question Is there a way in the schema form designer, by updating the schema source, or through code to offer the same (RTF) hyperlink drop-down options, but in a single field? I could be missing something, but recognize this scenario isn't supported OOTB.

• Using repaint() method.

  - by owca

  I'm still struggling to create this game : http://stackoverflow.com/questions/2844190/choosing-design-method-for-ladder-like-word-game .I've got it almost working but there is a problem though. When I'm inserting a word and it's correct, the whole window should reload, and JButtons containing letters should be repainted with different style. But somehow repaint() method for the game panel (in Main method) doesn't affect it at all. What am I doing wrong ? Here's my code: Main: import java.util.Scanner; import javax.swing.*; import java.awt.*; public class Main { public static void main(String[] args){ final JFrame f = new JFrame("Ladder Game"); Scanner sc = new Scanner(System.in); System.out.println("Creating game data..."); System.out.println("Height: "); //setting height of the grid while (!sc.hasNextInt()) { System.out.println("int, please!"); sc.next(); } final int height = sc.nextInt(); /* * I'm creating Grid[]game. Each row of game contains Grid of Element[]line. * Each row of line contains Elements, which are single letters in the game. */ Grid[]game = new Grid[height]; for(int L = 0; L < height; L++){ Grid row = null; int i = L+1; String s; do { System.out.println("Length "+i+", please!"); s = sc.next(); } while (s.length() != i); Element[] line = new Element[s.length()]; Element single = null; String[] temp = null; String[] temp2 = new String[s.length()]; temp = s.split(""); for( int j = temp2.length; j>0; j--){ temp2[j-1] = temp[j]; } for (int k = 0 ; k < temp2.length ; k++) { if( k == 0 ){ single = new Element(temp2[k], 2); } else{ single = new Element(temp2[k], 1); } line[k] = single; } row = new Grid(line); game[L] = row; } //############################################ //THE GAME STARTS HERE //############################################ //create new game panel with box layout JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); panel.setBackground(Color.ORANGE); panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); //for each row of the game array add panel containing letters Single panel //is drawn with Grid's paint() method and then returned here to be added for(int i = 0; i < game.length; i++){ panel.add(game[i].paint()); } f.setContentPane(panel); f.pack(); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); boolean end = false; boolean word = false; String text; /* * Game continues until solved() returns true.

• recursively implementing 'minimum number of coins' in python

  - by user5198

  This problem is same as asked in here. Given a list of coins, their values (c1, c2, c3, ... cj, ...), and the total sum i. Find the minimum number of coins the sum of which is i (we can use as many coins of one type as we want), or report that it's not possible to select coins in such a way that they sum up to S. I"m just introduced to dynamic programming yesterday and I tried to make a code for it. # Optimal substructure: C[i] = 1 + min_j(C[i-cj]) cdict = {} def C(i, coins): if i <= 0: return 0 if i in cdict: return cdict[i] else: answer = 1 + min([C(i - cj, coins) for cj in coins]) cdict[i] = answer return answer Here, C[i] is the optimal solution for amount of money 'i'. And available coins are {c1, c2, ... , cj, ...} for the program, I've increased the recursion limit to avoid maximum recursion depth exceeded error. But, this program gives the right answer only someones and when a solution is not possible, it doesn't indicate that. What is wrong with my code and how to correct it?
