• Hashing Function for Map C++

  - by Josh

  I am trying to determine a hash function which takes an input (i, k) and determines a unique solution. The possible inputs for (i, k) range from 0 to 100. Consider each (i, k) as a position of a node in a trinomial tree. Ex: (0, 0) can diverge to (1, 1) (1, 0) (1, -1). (1, 1) can diverge to (2, 2) (2, 1) (2, 0). Sample given here: http://www.google.com/imgres?imgurl=http://sfb649.wiwi.hu-berlin.de/fedc_homepage/xplore/tutorials/stfhtmlimg1156.gif&imgrefurl=http://sfb649.wiwi.hu-berlin.de/fedc_homepage/xplore/tutorials/stfhtmlnode41.html&h=413&w=416&sz=4&tbnid=OegDZu-yeVitZM:&tbnh=90&tbnw=91&zoom=1&usg=__9uQWDNYNLV14YioWWbrqPgfa3DQ=&docid=2hhitNyRWjI_DM&hl=en&sa=X&ei=xAfFUIbyG8nzyAHv2YDICg&ved=0CDsQ9QEwAQ I am using a map map <double, double> hash_table I need a key value to be determined from pairs (i, k) to hash to to value for that (i, k) So far I was only able to come up with linear functions such as: double Hash_function(int i, int k) { //double val = pow(i, k) + i; //return (val % 4294967296); return (i*3.1415 + k*i*9.12341); } However, I cannot determine a unique key with a certain (i, k). What kind of functions can I use to help me do so?

• WCF Service returning 400 error: The body of the message cannot be read because it is empty

  I have a WCF service that is causing a bit of a headache. I have tracing enabled, I have an object with a data contract being built and passed in, but I am seeing this error in the log: <TraceData> <DataItem> <TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Error"> <TraceIdentifier>http://msdn.microsoft.com/en-US/library/System.ServiceModel.Diagnostics.ThrowingException.aspx</TraceIdentifier> <Description>Throwing an exception.</Description> <AppDomain>efb0d0d7-1-129315381593520544</AppDomain> <Exception> <ExceptionType>System.ServiceModel.ProtocolException, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType> <Message>There is a problem with the XML that was received from the network.

Any ideas why? I've tried upping the object graph and the message size. When I debug it stops in the wrapper class with the 400 error. I'm not sure if there is a serialization error, but considering the object contract is 4 integer properties I can't imagine it causing an issue.

• Data Annotations validation Built into model

  - by Josh

  I want to build an object model that automatically wires in validation when I attempt to save an object. I am using DataAnnotations for my validation, and it all works well, but I think my inheritance is whacked. I am looking here for some guidance on a better way to wire in my validation. So, to build in validation I have this interface public interface IValidatable { bool IsValid { get; } ValidationResponse ValidationResults { get; } void Validate(); } Then, I have a base class that all my objects inherit from. I did a class because I wanted to wire in the validation calls automatically. The issue is that the validation has to know the type of the class is it validating. So I use Generics like so. public class CoreObjectBase<T> : IValidatable where T : CoreObjectBase<T> { #region IValidatable Members public virtual bool IsValid { get { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // return false if any violations occurred return !result.HasViolations; } } public virtual ValidationResponse ValidationResults { get { var result = new Validator<T>().Validate((T)this); return result; } } public virtual void Validate() { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // throw error if any violations were detected if (result.HasViolations) throw new RulesException(result.Errors); } #endregion } So, I have this circular inheritance statement. My classes look like this then: public class MyClass : CoreObjectBase<MyClass> { } But the problem occurs when I have a more complicated model. Because I can only inherit from one class, when I have a situation where inheritance makes sense I believe the child classes won't have validation on their properties. public class Parent : CoreObjectBase<Parent> { //properties validated } public class Child : Parent { //properties not validated? } I haven't really tested the validation in these cases yet, but I am pretty sure that anything in child with a data annotation on it will not be automatically validated when I call Child.Validate(); due to the way the inheritance is configured. Is there a better way to do this?

• Do validations still fire in ASP.NET even if the controls are hidden?

  - by Josh

  I have a form that uses ASP.NET validations. I am using some inline C# in the aspx to show/hide certain controls depending on a user's role. I would use the Visible property, but there are so many of them, I just decided to do inline C# to show and hide (I know, not best practice, but bear with me for a second). I am having an issue where Page.IsValid is always set to False when I submit my form (when certain fields are being hidden). Will the validations still fire off even if the controls are not even rendered on the pag? Also, if this is not the case, is there an effective way of breaking down Page.IsValid to find out what is setting it to False? Thanks.

• CSS issue with multi-accordion

  - by Josh

  Alright, I got some help earlier with this, but it never truly got resolved. I'm pretty sure I'm having a CSS issue, but I just can't figure out how to correct it. Currently, I have these accordions working perfectly, they collapse, expand, expand again when told to etc. The problem I'm having is aligning the content within these accordion divs. Ideally, when everything is default (collapsed) all I want seen is the thumbnail image and the Headline. Then if the user wishes, they click on the headline and it expands and if they want to make a comment or view comments, they can click once again to expand that. Here's the thing, I have to make the height 62px so everything will fit in and just not float all over the place. This creates a problem with the "View Comments" to "Text Here" area, as you can tell it has outrageous space between the two. The other issue is, as I currently have it I'm forcefully indenting the article text so that it doesn't TEXT WRAP underneath the thumbnail image. Basically, I want it split into 2 columns so nothing ever goes beneath the image, but working with this accordion and divs inside the divs it's proving to be difficult for me. I've put up a demo here: http://www.notedls.com/demo

• Problem with displaying my Image..

  - by Josh

  Here is my full problem so if anyone has any ideas or can offer some help, please let me know. I have a Website that will generate a Report and this Report takes some time to create. There is a MyReport.ASPX file that has a form1, Image1, and a ReportViewer control. There is also a MyReport.cs file that has C# code to generated a HTMLText string that the ReportViewer control will display. When I pull the Website up in the browser, the MyReport.cs file creates the Report before MyReport.ASPX ever gets called so my Image1 (which I need to display while the Report is being created) never gets displayed until AFTER the Report is created and displayed. What do you suggest I do here? If I did not supply enough information, please let me know what else you need to know and I will gladly post it. Thanks,

• Passing a pointer to an array to glGenBuffers

  - by Josh Elsasser

  I'm currently passing an array to a function, then attempting to use glGenBuffers with the array that is passed to the function. I can't figure out a way to get glGenBuffers to work with the array that I've passed. I have a decent grasp of the basics of pointers, but this is beyond me. This is basically how the render code works. It's a bit more complex, (colours using the same array idea, also not working) but the basic idea is as follows: void drawFoo(const GLfloat *renderArray, GLuint verticeBuffer) { glBindBuffer(GL_ARRAY_BUFFER, verticeBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(verticeBuffer)*sizeof(GLfloat), verticeBuffer, GL_STATIC_DRAW); glVertexPointer(2, GL_FLOAT, 0, 0); glEnableClientState(GL_VERTEX_BUFFER); glDrawArrays(GL_TRIANGLE_FAN, 0, 45); glDisableClientState(GL_VERTEX_BUFFEr); } Thanks in advance for the help

• how to convert legacy query to ActiveRecord Rails way

  - by josh

  I have a query in my code as below @sqladdpayment = "INSERT INTO payments (orderid, ttlprodcost, paytype, paystatus,created_at,updated_at,userid,storeid) VALUES ('" + session[:ordersid] + "', '" + session[:totalcost] + "', '" + "1"+ "', '" + "complete" +"',current_date, current_date, '"+"1"+"','"+ "1"+"')" Here the table payments and primary key is orderid. Now, I know if I convert this to the ActiveRecord way then I will not have to put update_date, current_date because it will put that on it's own. It will also put orderid on it's own also (auto_increment). I am looking for a way to convert the above query to ActiveRecord Rails way but still be able to put orderid on my own (session[:ordersid]). I do not want to rely on auto_increment because then I will have to refactor lot of the other code. This might be a quick and dirty fix but I want to know whether this type of flexibility is offered in rails? I have wondered about this question many times. Why won't rails allow me to have that flexibility?

• Content cacheing with PHP and CodeIgniter

  - by Josh K

  I have a couple of things I'm working on, namely a page that issues five or six cURL requests and processing content on them. I'm working with CodeIgniter on a LAMP stack but am open to other options. Naturally I would prefer to not rewrite the application. I would like to know if there are any ready-made / easily learned caching methods. Primarily I'd like to check if the page has changed since I last scrapped it. If it has, redownload and present. If it hasn't, serve up a cached copy.

• How can I improve this SQL to avoid several problems with its results?

  - by Josh Curren

  I am having some problems with trying to search. Currently this will only return results that have at least 1 row in the maintenance_parts table. I would like it to return results even if there are 0 parts rows. My second problem is that when you search for a vehicle and it should return multiple results (multiple maintenance rows) it will only return 1 result for that vehicle. Some Background Info: The user has 2 fields to fill out. The fields are vehicle and keywords. The vehicle field is meant to allow searching based on the make, model, VIN, truck number (often is 2 - 3 digits or a letter prefix followed by 2 digits), and a few other fields that belong to the truck table. The keywords are meant to search most fields in the maintenance and maintenance_parts tables (things like the description of the work, parts name, parts number). The maintenance_parts table can contain 0, 1, or more rows for each maintenance row. The truck table contains exactly 1 row for every maintenance row. A truck can have multiple maintenance records. "SELECT M.maintenance_id, M.some_id, M.type_code, M.service_date, M.mileage, M.mg_id, M.mg_type, M.comments, M.work_done, MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) + MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) + MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) AS score FROM maintenance M, maintenance_parts P, truck T WHERE M.maintenance_id = P.maintenance_id AND M.some_id = T.truck_id AND M.type_code = 'truck' AND ( (MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) OR T.truck_number LIKE '%$vehicle%') OR MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) OR MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) ) AND M.status = 'A' GROUP BY maintenance_id ORDER BY score DESC, maintenance_id DESC LIMIT 0, $limit"

• Python: Behavior of object in set operations

  - by Josh Arenberg

  I'm trying to create a custom object that behaves properly in set operations. I've generally got it working, but I want to make sure I fully understand the implications. In particular, I'm interested in the behavior when there is additional data in the object that is not included in the equal / hash methods. It seems that in the 'intersection' operation, it returns the set of objects that are being compared to, where the 'union' operations returns the set of objects that are being compared. To illustrate: class MyObject: def __init__(self,value,meta): self.value = value self.meta = meta def __eq__(self,other): if self.value == other.value: return True else: return False def __hash__(self): return hash(self.value) a = MyObject('1','left') b = MyObject('1','right') c = MyObject('2','left') d = MyObject('2','right') e = MyObject('3','left') print a == b # True print a == c # False for i in set([a,c,e]).intersection(set([b,d])): print "%s %s" % (i.value,i.meta) #returns: #1 right #2 right for i in set([a,c,e]).union(set([b,d])): print "%s %s" % (i.value,i.meta) #returns: #1 left #3 left #2 left Is this behavior documented somewhere and deterministic? If so, what is the governing principle?

• In SQL, how can I count the number of values in a column and then pivot it so the column becomes the

  - by Josh Yeager

  I have a survey database with one column for each question and one row for each person who responds. Each question is answered with a value from 1 to 3. Id Quality? Speed? -- ------- ----- 1 3 1 2 2 1 3 2 3 4 3 2 Now, I need to display the results as one row per question, with a column for each response number, and the value in each column being the number of responses that used that answer.

• Processing data from an AJAX request

  - by Josh K

  I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

• How do I map a macro across a list in Scheme?

  I have a Scheme macro and a long list, and I'd like to map the macro across the list, just as if it were a function. How can I do that using R5RS? The macro accepts several arguments: (mac a b c d) The list has (define my-list ((a1 b1 c1 d1) (a2 b2 c2 d2) ...

• Zend Framework - How do make a hierarchy without it being a module?

  - by Josh

  Here is my specific issue. I want to make an api level which then under that you can select which method you will use. For example: test.com/api/rest test.com/api/xmlprc Currently I have api mapping to a module directory. I then setup a route to make it a rest route. test.com/api is a rest route, but I would rather have it be test.com/api/rest. This would allow me later to add others. In Bootstrap.php: $front = Zend_Controller_Front::getInstance(); $router = $front->getRouter(); $route = new Zend_Controller_Router_Route( 'api/:module/:controller/:id/*', array('module' =>'default') ); $router-addRoute('api', $route); $restRoute = new Zend_Rest_Route($front, array(), array( 'rest' )); $router-addRoute('rest', $restRoute); return $router; In application.ini: resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" I know it will involve routes, but sometimes I find the Zend Framework documentation to be a little hard to follow. When I go to test.com/rest/controller/ it works how it should, but if I go to test.com/api/rest/ it tells me that my module is api and controller is rest.

• Fluent Nhibernate mapping related items

  - by Josh

  I am trying to relate 2 items. I have a table that is simply an Id field, and then 2 columns for the Item Id's to relate. I want it to be a 2 way relationship - that is, if the items appear twice in the table, I only want one relationship connection back. So, here's my item: public class Item { public virtual Guid ItemId {get; set;} public virtual string Name {get; set;} public virtual IList<Item> RelatedItems {get; set;} } The table for relating the items looks like this: CREATE TABLE RelatedItems ( RelatedItemId uniqueidentifier NOT NULL, ItemId uniqueidentifier NOT NULL, RelatedId uniqueidentifier NOT NULL, CONSTRAINT PK_RelatedItems PRIMARY KEY CLUSTERED (RelatedItemId) ) What is the best way to map this connection?

• Global Import/using Aliasing in .NET

  - by Josh Stodola

  Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: ' VB Imports Db = Company.Lib.Data.Objects // C# using Db = Company.Lib.Data.Objects; And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

• Is there a way to rotate an html table?

  Is there a way to rotate an html table? So, say I had a table like this: <table id="table-1" cellspacing="0" cellpadding="2"> <tr><td>1</td></tr> <tr><td>2</td></tr> <tr><td>3</td></tr> <tr><td>4</td></tr> <tr><td>5</td></tr> <tr><td>6</td></tr> </table> and wanted to some sort of button that had javascript behind it that could rotate the table any which direction. For example, clicking the right button, results in: <table id="table-1" cellspacing="0" cellpadding="2"> <tr><td>6</td><td>5</td><td>4</td><td>3</td><td>2</td><td>1</td></tr> </table> I have a drag and drop plugin that uses a table, and I am trying to do a piece that allows for a user to add to a queue (that results in the table), and then they can also rotate it around as well.

I have this in my .h: typedef enum { kPacketTypeScore, } EPacketTypes; typedef struct { EPacketTypes type; size_t size; } SPacketInfo; typedef struct { SPacketInfo packetInfo; int score; } SScorePacket; Then .m: Sending data: scoreData *score = [scoreData sharedData]; SScorePacket packet; packet.packetInfo.type = kPacketTypeScore; packet.packetInfo.size = sizeof(SScorePacket); packet.score = score.score; NSData* dataToSend = [NSData dataWithBytes:&packet length:packet.packetInfo.size]; NSError *error; [self.myMatch sendDataToAllPlayers: dataToSend withDataMode: GKMatchSendDataUnreliable error:&error]; if (error != nil) { // handle the error } Receiving: SPacketInfo* packet = (SPacketInfo*)[data bytes]; switch (packet->type) { case kPacketTypeScore: { SScorePacket* scorePacket = (SScorePacket*)packet; scoreData *score = [scoreData sharedData]; [scoreLabel setString:[NSString stringWithFormat:@"You: %d Challenger: %d", score.score, scorePacket]]; break; } default: CCLOG(@"received unknown packet type %i (size: %u)", packet->type, packet->size); break; } Any ideas? Thanks.
