• Setting slime-enable-evaluate-in-emacs

  - by Tyler

  Hi, I am using SBCL with slime, and have the following code: (swank::eval-in-emacs '(with-current-buffer (slime-repl-buffer) (insert (propertize "foo" 'font-lock-face '(:foreground "red"))))) (print "here is some text") In general if I try to execute anything with swank:: prefixed to it emacs will give a security error, and this particular one tells me I need to set slime-enable-evaluate-in-emacs to true. Where is this value? I haven't been able to find a slime or swank config. & settings file. Thanks much.

• Do FormViews not respond to commands issued from an ImageButton?

  - by Duke

  I am using ImageButtons in place of LinkButtons in a FormView to issue New/Edit/Delete/Cancel commands, but they don't seem to have an effect on the FormView. The ImageButtons will cause a postback but the FormView mode doesn't change from the current mode. I'm sure the ImageButtons were working at one point, but I've been busy with other pages for a while. The only thing that's changed between now and then are some patches I installed in Visual Studio. I haven't been able to find any information related to this issue other than this: http://www.codeproject.com/KB/webforms/TamingTheFormView.aspx In that article there's an onclick method for an ImageButton that's used to change the FormView mode. Would that be the only way to use ImageButtons instead of LinkButtons in a FormView?

• Setting thread culture to default

  - by synergetic

  In silverlight application I have MyTexts.resx (for english) and MyTexts.ja-JP.resx (for japanese) resource files. Before loading a page I can set current culture to japanese as following: Thread.CurrentThread.CurrentCulture = new CultureInfo("ja-JP"); Thread.CurrentThread.CurrentUICulture = new CultureInfo("ja-JP"); But sometimes I need to reset culture to default. How can I do that? The following wouldn't work: Thread.CurrentThread.CurrentCulture = new CultureInfo("default"); OR Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");

• Configuring Multiple ASP.NET MVC Sites To Use a Single Database For Authentication/Membership

  - by Maxim Z.

  Is it possible for two or more ASP.NET MVC sites to use a single SQL Server database for authentication and other things? Here's how I'm thinking of setting it up: I will combine the current database of each site into one single database, prefixing the tables with the name of the site they belong to. I currently have authentication tables generated by the asp.net_regsql.exe utility. How should I combine those tables? I'm guessing that the way to do it is to somehow set the "application_id" column in those tables... Thanks in advance.

• Throw a long list of exceptions vs throw an Exception vs throw custom exception?

  - by athena

  I have an application which uses two methods of an API. Both these methods throw more than five exceptions each. So, if I just add a throws declaration then it becomes a list of more than ten. (My method cannot handle any of the ten exceptions) I have read that throwing a long list of exceptions is a bad practice. Also throwing (the umbrella) Exception is a bad practice. So, what should I do? Add a try catch block, and log and exit in the catch block? (Current approach) Create a custom exception class, wrap every exception and throw the custom exception? Add a throws declaration for all exceptions? Throw Exception?

• add schema to path in postgresql

  - by veilig

  I'm the process of moving applications over from all in the public schema to each having their own schema. for each application, I have a small script that will create the schema and then create the tables,functions,etc... to that schema. Is there anyway to automatically add a newly created schema to the search_path? Currently, the only way I see is to find the users current path SHOW search_path; and then add the new schema to it SET search_path to xxx,yyy,zzz; I would like some way to just say, append schema zzz to the users_search path. is this possible?

• How to properly siglongjmp out of signal handler?

  - by EpsilonVector

  Suppose I have the following code: In order to implement a context switch I activate ualarm and when it jumps to the handler it setjmp's the current context, and longjmps to the next, expecting to eventually return to the alarm handler and longjmped back into this context (the contexts are cycled through in a Round Robin). For this I need to keep SIGALRM unblocked in between alarm_handlers. I came up with the following code, which doesn't seem to work. What's wrong with it and what is the right way to do this? void alarm_handler(){ if(sigsetjmp(toc->threads[toc->RR_pointer].env, 0)){ ualarm(200, 0); signal(SIGALRM, alarm_handler); return; } get_next_context_number(toc->RR_pointer); //is a macro for (j=0; j<10; j++) printf("ALARM HANDLER\n"); siglongjmp(toc->threads[toc->RR_pointer].env, 1); }

• Creating a new nested resource

  - by Bobby B

  I'm working on a basic garden logging application which consists of gardens, plants and planted plants. Each user has one or many gardens, plants are master definitions, and a planted plant can be thought of as an instance of a plant in a specific user's garden. In my routes.rb file I have the following: map.resources :gardens do |gardens| gardens.resources :planted_plants, :has_many => :plant_log_entries, :collection => { :filter => :post, :choose_garden => :post} gardens.resources :garden_log_entries end map.resources :plants This makes sense to me when retrieving a list of planted_plants in a user's garden, but I'd like to create a planted_plant record from the index of plant. The problem is, a user can have multiple gardens. How can I create a new form for a planted_plant that allows the user to specify which garden should be used? The current route requires a garden_id - which makes sense for retrieval, but I'd like to supply that as a parameter for creation. Thanks in advance for any help!

• Setting up a SQL Membership Provider and attaching the MDF file in Visual Studio 2008

  - by aubreyrhodes

  I'm trying to set up a SQL Membership Provider for an ASP.NET MVC 1.0 and I'm having problems setting up the tables and stored procedures in the database. I've tried attaching both the applications current database and a blank database to my local SQLEXPRESS instance (using SSEUtil) and then running the aspnet_regsql wizard against them. When I detach the mdf file and try to load it in Visual Studio 2008, the data connection in the server explorer shows that the database has no tables or stored procedures. Am I missing a step or something here? I've been having a heap of trouble with compatibility between Visual Studio and SQLEXPRESS.

• Is it good practice to call module functions directly in VB.NET?

  - by froadie

  I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?

• Speed up dialog/page transitions in jQuery Mobile on iPhone?

  - by Crashalot

  There are other SO questions on speeding up jQuery Mobile for Android, but does anyone know how to accelerate page transitions on iPhones, specifically dialog transitions? We're on JQM 1.0. JQM 1.1 is supposed to speed up page transitions (though we haven't seen any demos yet), but we're wondering if anyone has done anything for JQM 1.0. Right now, there is a two second delay, which is too much to show a dialog. We resort to one of two options. Using no animation for the page transition, which provides instant feedback, or rolling our own by binding to "touchstart" and animating the dialog, which is really just a big DIV inside the current page. Neither is ideal. Suggestions?

• Google Maps within a dynamically loaded jquery Accordion

  - by marr75

  I'm trying to load a google map within a jquery ui accordion with contents loaded by ajax. $("h2", "#accordion").click(function(e) { var contentDiv = $(this).next("div"); if (contentDiv.children().length == 1) { contentDiv.load($(this).find("a").attr("href")); contentDiv.ready(function(){ var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); }) } }); That's my current code (Google Maps API V3), but it redirects to the url of the href when I click currently, obviously with no google map because there's no javascript in this response. If I comment out the map line everything works fine (except the map itself).

• Disable apache catch-all subdomain

  - by Lukas F

  Hi, I have a problem with my apache2 configuration and I hope someone here can help me. There is one server with one IP and a few domains. http://123.123.123.123 should have /var/www/123.123.123.123 as DocumentRoot http://www.domain1.com should have /var/www/domain1.com as DocumentRoot http://blog.domain1.com should have /var/www/blog.domain1.com as DocumentRoot http://www.domain2.com should have /var/www/domain2.com as DocumentRoot and http://bullshit.domain1.com along with all other non-existing subdomains on both domains should return a 404 page. What am I doing wrong? That can't be so hard, and I'm sure I had it working before... In my current config all subdomains show the /var/www/123.123.123.123. I guess because thats the first VirtualHost apache is reading.

• Problem Using Partial View In for each loop

  - by leen3o

  I'm a little confused here, I am trying use a partial view in a for each loop like so <% foreach (var item in (IEnumerable<MVCLD.Models.Article>)ViewData["LatestWebsites"]){%> <% Html.RenderPartial("articlelisttemaple", item); %> <% } %> And my partial view looks like this <div class="listingholders"> <h4><%=Html.ActionLink(item.ArticleTitle, "details", "article", new { UrlID = item.UrlID, ArticleName = item.ArticleTitle.ToString().niceurl() }, null)%> </h4> <p><%= Html.Encode(item.ArticleSnippet) %></p> <div class="clearer">&nbsp;</div> </div> But when I run the project I get told the partial view doesn't understand what item is?? CS0103: The name 'item' does not exist in the current context I can't see why it would be doing this as I'm passing item into the partial view?

• Finding the heaviest length-constrained path in a weighted Binary Tree

  - by Hristo

  UPDATE I worked out an algorithm that I think runs in O(n*k) running time. Below is the pseudo-code: routine heaviestKPath( T, k ) // create 2D matrix with n rows and k columns with each element = -8 // we make it size k+1 because the 0th column must be all 0s for a later // function to work properly and simplicity in our algorithm matrix = new array[ T.getVertexCount() ][ k + 1 ] (-8); // set all elements in the first column of this matrix = 0 matrix[ n ][ 0 ] = 0; // fill our matrix by traversing the tree traverseToFillMatrix( T.root, k ); // consider a path that would arc over a node globalMaxWeight = -8; findArcs( T.root, k ); return globalMaxWeight end routine // node = the current node; k = the path length; node.lc = node’s left child; // node.rc = node’s right child; node.idx = node’s index (row) in the matrix; // node.lc.wt/node.rc.wt = weight of the edge to left/right child; routine traverseToFillMatrix( node, k ) if (node == null) return; traverseToFillMatrix(node.lc, k ); // recurse left traverseToFillMatrix(node.rc, k ); // recurse right // in the case that a left/right child doesn’t exist, or both, // let’s assume the code is smart enough to handle these cases matrix[ node.idx ][ 1 ] = max( node.lc.wt, node.rc.wt ); for i = 2 to k { // max returns the heavier of the 2 paths matrix[node.idx][i] = max( matrix[node.lc.idx][i-1] + node.lc.wt, matrix[node.rc.idx][i-1] + node.rc.wt); } end routine // node = the current node, k = the path length routine findArcs( node, k ) if (node == null) return; nodeMax = matrix[node.idx][k]; longPath = path[node.idx][k]; i = 1; j = k-1; while ( i+j == k AND i < k ) { left = node.lc.wt + matrix[node.lc.idx][i-1]; right = node.rc.wt + matrix[node.rc.idx][j-1]; if ( left + right > nodeMax ) { nodeMax = left + right; } i++; j--; } // if this node’s max weight is larger than the global max weight, update if ( globalMaxWeight < nodeMax ) { globalMaxWeight = nodeMax; } findArcs( node.lc, k ); // recurse left findArcs( node.rc, k ); // recurse right end routine Let me know what you think. Feedback is welcome. I think have come up with two naive algorithms that find the heaviest length-constrained path in a weighted Binary Tree. Firstly, the description of the algorithm is as follows: given an n-vertex Binary Tree with weighted edges and some value k, find the heaviest path of length k. For both algorithms, I'll need a reference to all vertices so I'll just do a simple traversal of the Tree to have a reference to all vertices, with each vertex having a reference to its left, right, and parent nodes in the tree. Algorithm 1 For this algorithm, I'm basically planning on running DFS from each node in the Tree, with consideration to the fixed path length. In addition, since the path I'm looking for has the potential of going from left subtree to root to right subtree, I will have to consider 3 choices at each node. But this will result in a O(n*3^k) algorithm and I don't like that. Algorithm 2 I'm essentially thinking about using a modified version of Dijkstra's Algorithm in order to consider a fixed path length. Since I'm looking for heaviest and Dijkstra's Algorithm finds the lightest, I'm planning on negating all edge weights before starting the traversal. Actually... this doesn't make sense since I'd have to run Dijkstra's on each node and that doesn't seem very efficient much better than the above algorithm. So I guess my main questions are several. Firstly, do the algorithms I've described above solve the problem at hand? I'm not totally certain the Dijkstra's version will work as Dijkstra's is meant for positive edge values. Now, I am sure there exist more clever/efficient algorithms for this... what is a better algorithm? I've read about "Using spine decompositions to efficiently solve the length-constrained heaviest path problem for trees" but that is really complicated and I don't understand it at all. Are there other algorithms that tackle this problem, maybe not as efficiently as spine decomposition but easier to understand? Thanks.

• Opening Another Xib form an Xib

  - by Goods

  Not a Noob as yesterday, but still green. I have been playing around with the code that Elisabeth Robson has put together HERE. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I put a 'Learn More' button on the current xib(BookDetailView). I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Ive Tried IBAction and Pushing the Newer xib to the top. Do I need to create another view controller? Thanks for looking.

• product suggestion based on user data

  - by Enkay

  I'm trying to add suggestions to product pages along the lines of : "Customers who purchased this item also purchased x and y". The way the data is compiled right now is a mysql table with 3 rows. PRODUCT | CUSTOMER |QUANTITY Product is the product ID. Customer is the customer ID. Quantity is the number of time that product was bought by that customer. For each product description page, the system needs to figure out which users bought that product, what other products those users bought, in what quantity and then return the 2 products that were bought the most by people who bought the current product. Hopefully this makes sense and someone can point me in the right directions as to what the mysql query should look like. Thanks.

• javscript delay output

  - by tazim

  I have written some code to display server's current date and time on browser every time user clicks the button . I have done this using ajax in django with the help of jquery. Now my, problem is I have to continously display the date and time once the button is clicked . Some Sample code or utilities allowing such kind of delay will be helpful . Thanks in advance The template is : $(document).ready(function() { $("button").click(function() { $.ajax({ type: "POST", url :"/showdate/", datatype: "json ", success : function(data){ var s = data.currentdate; var sd = s $(sd).appendTo("div"); } }); }); }); <button type="button">Click Me</button> <div id="someid"></div> The view function is : def showdate(request): now = datetime.datetime.now() string_now = str(now) return_dict = {'currentdate':string_now} json = simplejson.dumps(return_dict) return HttpResponse(json,mimetype="application/json")

• How to include associative table information and still retain strong typing

  - by mwright

  I am using LINQ to SQL to create strongly typed objects in my project. Let's say I have an object that is represented by a database table. This object has a "Current State" that is kept in an associative table. I would like to make a single db call where I pull back the two tables joined but am unsure how I should be populating that information into some sort of object to preserve strong typing within my model so that the view using the information can just consume the information from the objects. I looked into creating a view model for this but it doesn't seem to quite fit. Am I thinking about this in the wrong way? What information can I include to help clarify my problem? Other details that may or may not be important: It's an MVC project....

• Rails can't render polymorphic associations to XML?

  - by ambertch

  When I render XML with an :include clause for a polymorphic association I have, it doesn't work. I end up with the XML returning the object pointers instead of the actual objects, like: <posts> #<Comment:0x102ed1540>#<Comment:0x102ecaa38>#<Comment:0x102ec7fe0>#<Comment:0x102ec3cd8> </posts> Yet as_json works! When I render JSON with :include clause, the associations are rendered correctly and I get something like: posts":[ {"type":"Comment","created_at":"2010-04-20T23:02:30-07:00","id":7,"content":"fourth comment"}, {"type":"Comment","created_at":"2010-04-20T23:02:26-07:00","id":6,"content":"third comment"}] My current workaround is using XML builder, but I'm not too comfortable with that in the long run. Does anyone happen to know about this issue? I'm kind of in a catch-22 because while XML doesn't render the associations, as_json doesn't render in a kosher json format (returns an array rather than a list of hashes as proper json should) and the deserializer I'm using on the client side would require modification to parse the json correctly.

• Java Future and infinite computation

  - by Chris

  I'm trying to optimize an (infinite) computation algorithm. I have an infinte Sum to calculate ( Summ_{n- infinity} (....) ) My idea was to create several threads using the Future < construct, then combine the intermediate results together. My problem hoewer is that I need a certain precision. So I need to constantly calculate the current result while other threads keep calculating. My question is: Is there some sort of result queue where each finished thread can put its results in, while a main thread can receive those results and then either lets the computation continues or terminate the whole ExecutorService? Any Help would really be appreciated! Thanks!

• How do I do this Database Model in Django?

  - by alex

  Django currently does not support the "Point" datatype in MySQL. That's why I created my own. class PointField(models.Field): def db_type(self): return 'Point' class Tag(models.Model): user = models.ForeignKey(User) utm = PointField() As you can see, this works, and syncdb creates the model fine. However, my current code calculates a length between two Points using raw SQL. cursor.execute("SELECT user_id FROM life_tag WHERE\ (GLength(LineStringFromWKB(LineString(asbinary(utm), asbinary(PointFromWKB(point(%s, %s)))))) < 55)... This says: Select where the length between the given point and the table point is less than 55. How can I do this with Django instead of RAW SQL? I don't want to do cursors and SELECT statements anymore. How can I modify the models.py in order to do this?

• Jquery Datepicker not selecting the default date

  - by Chirantan

  I have my datepicker set up like this $("#scheduled_date_163").datepicker({ onSelect: function(dateText, inst) { jQuery.get("/tasks/inplace_edit?id=scheduled_date_163&class_name=Task&value=" + dateText, function(data){ $('#scheduled_date_163').html(data); $('#scheduled_date_163').removeClass('hasDatepicker'); }) } }); $('#scheduled_date_163').datepicker( "option", "defaultDate", $.datepicker.parseDate("d m y", "31 8 2009") ); As you can see the date is hardcoded. It is supposed to be replaced with some code. However, the datepicker refuses to pick the date up! It always shows me the current date. Unable to figure out why. I even tried giving the date in string and +7 etc. But today's date itself is shown as the default date. What could be causing this?

• ASP.NET MVC AuthorizeAttribute passing values to ActionMethod?

  - by subskii

  Hi everyone I'm only a newcomer to ASP.NET MVC and am not sure how to achieve a certain task the "right way". Essentially, I store the logged in userId in HttpContext.User.Identity and have written an EnhancedAuthorizeAttribute to perform some custom authorization. In the overriden OnAuthorization method, my domain model hits the database to ensure the current user id can access the passed in routeValue "BatchCode". The prototype is: ReviewGroup GetReviewGroupFromBatchCode(string batchCode); It will return null if the user can't access the ReviewGroup and the OnAuthorization then denies access. Now, I know the decorated action method will only get executed if OnAuthorization passes, but I don't want to hit the database a second time to get the ReviewGroup again. I am thinking of storing the ReviewGroup in HttpContext.Items["reviewGroup"] and accessing this from the controller at the moment. Is this a feasible solution, or am I on the wrong path? Thanks!

• Appending Dataset in Core Data execution of Update through iTuneStore

  - by Yoon Lee

  So I have completed my code work. This is first time releasing the app through iTuneStore. Current state of reading Core Data (.sqlite) file is already prefetched (already has information like apple's 'Reciepie' program). Assuming I have successfully released through apple store, and decide to update my application to existing users. Say I have sqlite contents but it contains bit more information than previous SQLite file under same structure. Question 1. Every time update held to the existing user, does it removes previous ones and move new updated application? Question 2. if it is not, then HOW can I append the existing sql value?
