Advice on my jQuery Ajax Function

- by NessDan

So on my site, a user can post a comment on 2 things: a user's profile and an app. The code works fine in PHP but we decided to add Ajax to make it more stylish. The comment just fades into the page and works fine. I decided I wanted to make a function so that I wouldn't have to manage 2 (or more) blocks of codes in different files. Right now, the code is as follows for the two pages (not in a separate .js file, they're written inside the head tags for the pages.): // App page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "app.php?id=<?php echo $id; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); And next up, // Profile page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "profile.php?username=<?php echo $user; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); Now, on each page the box names will always be the same (comment_box and comment_submit) so what do you guys think of this function (Note, the postComment is in the head tag on the page.): // On the page, (profile.php) $(function() { $("input#comment_submit").click(function() { postComment("profile", "<?php echo $user ?>", "<?php echo $_SESSION['username']; ?>", "<?php echo date("M. d, Y", time()) ?>", "<?php echo date("g:i A", time()); ?>"); }); }); Which leads to this function (which is stored in a separate file called functions.js): function postComment(page, argvalue, username, date, time) { if (page == "app") { var arg = "id"; } if (page == "profile") { var arg = "username"; } var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: page + ".php?" + arg + "=" + argvalue, data: {comment: comment}, success: function() { $("textarea#comment_box").attr("disabled", "disabled") $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"" + page + ".php?" + arg + "=" + username + "\" class=\"commentname\">" + username + "</a><p class=\"commentdate\">" + date + " - " + time + "</p><p class=\"commentpost\">" + nl2br(comment) + "</p>").hide().fadeIn(1000); } }); return false; } That's what I came up with! So, some problems: When I hit the button the page refreshes. What fixed this was taking the return false from the function and putting it into the button click. Any way to keep it in the function and have the same effect? But my real question is this: Can any coders out there that are familiar to jQuery tell me techniques, coding practices, or ways to write my code more efficiently/elegantly? I've done a lot of work in PHP but I know that echoing the date may not be the most efficient way to get the date and time. So any tips that can really help me streamline this function and also make me better with writing jQuery are very welcome!

"Randomly" occurring errors...

- by ClarkeyBoy

Hi, My website has a setup whereby when the application starts a module called SiteContent is "created". This runs a clearup function which basically deletes any irrelevant data from the database, in case any has been left in there from previously run functions. The module has instances of Manager classes - namely RangeManager, CollectionManager, DesignManager. There are others but I will just use these as an example. Each Manager class contains an array of items - items may be of type Range, Collection or Design, whichever one is relevant. Data for each range is then read into an instance of Range, Collection or Design. I know this is basically duplicating data - not very efficient but its my final year project at the moment so I can always change it to use Linq or something similar later, when I am not pressured by the one month deadline. I have a form which, on clicking the Save button, saves data by calling SiteContent.RangeManager.Create(vars) or SiteContent.RangeManager.Update(Range As Range, vars) (or the equivalent for other manager classes, whichever one happens to be relevant). These functions call a stored procedure to insert or update in the relevant table. Classes Range, Collection and Design all have attributes such as Name, Description, Display and several others. When the Create or Update function is called, the Manager loops through all the other items to check if an item with the same name already exists. The Update function ensures that it does not compare the item being updated to itself. A custom exception (ItemAlreadyExistsException) is thrown if another item with the same name is found. For some weird reason, if I go into a Range, Collection or Design in edit mode, change something and try to update it, it occasionally doesnt update the item. When I say occasionally I mean every 3 - 4 page loads, sometimes more. I see absolutely no pattern in when or why it occurs. I have a try-catch statement which catches ItemAlreadyExistsException, and outputs "An item with this name already exists" when caught. Occasionally it will output this; other times it will not. Does anyone have any idea why this could happen? Maybe a mistake which someone has made and solved before? I used to have regular expressions in place that the names were compared to - I believe it was [a-zA-Z]{1, 100} (between 1 and 100 lower- or upper-case characters). For some reason the customer who I am developing the site for used to get errors saying its not in the correct format. Yet he could try the same text 5 minutes later and it would work fine. I am thinking this could well be the same problem, since both problems occur at random. Many thanks in advance. Regards, Richard Clarke Edit: After much time spent narrowing down the code, I have decided to wait till my brother, who has been a programmer for at least 8 years more than I have, to come down over Easter and get him to have a look at it. If he cant solve it then I will zip the files up and put them somewhere for people to access and have a go at. I narrowed it down literally to the minimum number of files possible, and it still occurs. It seems to be about every 10th time. Having said that, I force the manager classes to refresh every 10 page loads or 5 minutes (whichever one is sooner). I may look into this - this could be causing a problem. Basically each Manager contains an array of an object. This array is populated using data from the database. The Update function takes an instance of the item and the new values to be set for the object. If it happens to be a page load where the array is reset (ie the data is loaded freshly from the database) then the object instance with the same ID wont be the same instance as the one being passed in. This explains the fact that it throws an ItemAlreadyExistsException now and then. It all makes sense now the more I think about it. If I were to pass in the ID of the object to be altered, rather than the object itself, then it should work perfectly. I will answer the question if I solve it..

Crash when trying to get NSManagedObject from NSFetchedResultsController after 25 objects?

- by Jeremy

Hey everyone, I'm relatively new to Core Data on iOS, but I think I've been getting better with it. I've been experiencing a bizarre crash, however, in one of my applications and have not been able to figure it out. I have approximately 40 objects in Core Data, presented in a UITableView. When tapping on a cell, a UIActionSheet appears, presenting the user with a UIActionSheet with options related to the cell that was selected. So that I can reference the selected object, I declare an NSIndexPath in my header called "lastSelection" and do the following when the UIActionSheet is presented: // Each cell has a tag based on its row number (i.e. first row has tag 0) lastSelection = [NSIndexPath indexPathForRow:[sender tag] inSection:0]; NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; BOOL onDuty = [[managedObject valueForKey:@"onDuty"] boolValue]; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Status" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; if(onDuty) { [actionSheet addButtonWithTitle:@"Off Duty"]; } else { [actionSheet addButtonWithTitle:@"On Duty"]; } actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque; // Override the typical UIActionSheet behavior by presenting it overlapping the sender's frame. This makes it more clear which cell is selected. CGRect senderFrame = [sender frame]; CGPoint point = CGPointMake(senderFrame.origin.x + (senderFrame.size.width / 2), senderFrame.origin.y + (senderFrame.size.height / 2)); CGRect popoverRect = CGRectMake(point.x, point.y, 1, 1); [actionSheet showFromRect:popoverRect inView:[sender superview] animated:NO]; [actionSheet release]; When the UIActionSheet is dismissed with a button, the following code is called: - (void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex { // Set status based on UIActionSheet button pressed if(buttonIndex == -1) { return; } NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; if([actionSheet.title isEqualToString:@"Status"]) { if([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"On Duty"]) { [managedObject setValue:[NSNumber numberWithBool:YES] forKey:@"onDuty"]; [managedObject setValue:@"onDuty" forKey:@"status"]; } else { [managedObject setValue:[NSNumber numberWithBool:NO] forKey:@"onDuty"]; [managedObject setValue:@"offDuty" forKey:@"status"]; } } NSError *error; [self.managedObjectContext save:&error]; [tableView reloadData]; } This might not be the most efficient code (sorry, I'm new!), but it does work. That is, for the first 25 items in the list. Selecting the 26th item or beyond, the UIActionSheet will appear, but if it is dismissed with a button, I get a variety of errors, including any one of the following: [__NSCFArray section]: unrecognized selector sent to instance 0x4c6bf90 Program received signal: “EXC_BAD_ACCESS” [_NSObjectID_48_0 section]: unrecognized selector sent to instance 0x4c54710 [__NSArrayM section]: unrecognized selector sent to instance 0x4c619a0 [NSComparisonPredicate section]: unrecognized selector sent to instance 0x6088790 [NSKeyPathExpression section]: unrecognized selector sent to instance 0x4c18950 If I comment out NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; it doesn't crash anymore, so I believe it has something do do with that. Can anyone offer any insight? Please let me know if I need to include any other information. Thanks! EDIT: Interestingly, my fetchedResultsController code returns a different object every time. Is this expected, or could this be a cause of my issue? The code looks like this: - (NSFetchedResultsController *)fetchedResultsController { /* Set up the fetched results controller. */ // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. NSEntityDescription *entity = [NSEntityDescription entityForName:@"Employee" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; // Set the batch size to a suitable number. [fetchRequest setFetchBatchSize:80]; // Edit the sort key as appropriate. NSString *sortKey; BOOL ascending; if(sortControl.selectedSegmentIndex == 0) { sortKey = @"startTime"; ascending = YES; } else if(sortControl.selectedSegmentIndex == 1) { sortKey = @"name"; ascending = YES; } else { sortKey = @"onDuty"; ascending = NO; } NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:sortKey ascending:ascending]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Edit the section name key path and cache name if appropriate. NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; if (![fetchedResultsController_ performFetch:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. */ //NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return fetchedResultsController_; } This happens when I set a breakpoint: (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x61567c0> (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x4c83630>

Convert C++Builder AnsiString to std::string via boost::lexical_cast

- by David Klein

For a school assignment I have to implement a project in C++ using Borland C++ Builder. As the VCL uses AnsiString for all GUI Components I have to convert all of my std::strings to AnsiString for the sake of displaying. std::string inp = "Hello world!"; AnsiString outp(inp.c_str()); works of course but is a bit tedious to write and code duplication I want to avoid. As we use Boost in other contexts I decided to provide some helper functions go get boost::lexical_cast to work with AnsiString. Here is my implementation so far: std::istream& operator>>(std::istream& istr, AnsiString& str) { istr.exceptions(std::ios::badbit | std::ios::failbit | std::ios::eofbit); std::string s; std::getline(istr,s); str = AnsiString(s.c_str()); return istr; } In the beginning I got Access Violation after Access Violation but since I added the .exceptions() stuff the picture gets clearer. When the conversion is performed I get the following Exception: ios_base::eofbit set [Runtime Error/std::ios_base::failure] Does anyone have an idea how to fix it and can explain why the error occurs? My C++ experience is very limited. The conversion routine the other way round would be: std::ostream& operator<<(std::ostream& ostr,const AnsiString& str) { ostr << (str.c_str()); return ostr; } Maybe someone will spot an error here too :) With best regards! Edit: At the moment I'm using the edited version of Jem, it works in the beginning. After a while of using the programm the Borland Codeguard mentions some pointer arithmetic in already freed regions. Any ideas how this could be related?

setIncludesSubentities: in an NSFetchRequest is broken for entities across multiple persistent store

- by SG

Prior art which doesn't quite address this: http://stackoverflow.com/questions/1774359/core-data-migration-error-message-model-does-not-contain-configuration-xyz I have narrowed this down to a specific issue. It takes a minute to set up, though; please bear with me. The gist of the issue is that a persistentStoreCoordinator (apparently) cannot preserve the part of an object graph where a managedObject is marked as a subentity of another when they are stored in different files. Here goes... 1) I have 2 xcdatamodel files, each containing a single entity. In runtime, when the managed object model is constructed, I manually define one entity as subentity of another using setSubentities:. This is because defining subentities across multiple files in the editor is not supported yet. I then return the complete model with modelByMergingModels. //Works! [mainEntity setSubentities:canvasEntities]; NSLog(@"confirm %@ is super for %@", [[[canvasEntities lastObject] superentity] name], [[canvasEntities lastObject] name]); //Output: "confirm Note is super for Browser" 2) I have modified the persistentStoreCoordinator method so that it sets a different store for each entity. Technically, it uses configurations, and each entity has one and only one configuration defined. //Also works! for ( NSString *configName in [[HACanvasPluginManager shared].registeredCanvasTypes valueForKey:@"viewControllerClassName"] ) { storeUrl = [NSURL fileURLWithPath:[[self applicationDocumentsDirectory] stringByAppendingPathComponent:[configName stringByAppendingPathExtension:@"sqlite"]]]; //NSLog(@"entities for configuration '%@': %@", configName, [[[self managedObjectModel] entitiesForConfiguration:configName] valueForKey:@"name"]); //Output: "entities for configuration 'HATextCanvasController': (Note)" //Output: "entities for configuration 'HAWebCanvasController': (Browser)" if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:configName URL:storeUrl options:options error:&error]) //etc 3) I have a fetchRequest set for the parent entity, with setIncludesSubentities: and setAffectedStores: just to be sure we get both 1) and 2) covered. When inserting objects of either entity, they both are added to the context and they both are fetched by the fetchedResultsController and displayed in the tableView as expected. // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity:entity]; [fetchRequest setIncludesSubentities:YES]; //NECESSARY to fetch all canvas types [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setFetchBatchSize:20]; // Set the batch size to a suitable number. [fetchRequest setAffectedStores:[[managedObjectContext persistentStoreCoordinator] persistentStores]]; [fetchRequest setReturnsObjectsAsFaults:NO]; Here is where it starts misbehaving: after closing and relaunching the app, ONLY THE PARENT ENTITY is fetched. If I change the entity of the request using setEntity: to the entity for 'Note', all notes are fetched. If I change it to the entity for 'Browser', all the browsers are fetched. Let me reiterate that during the run in which an object is first inserted into the context, it will appear in the list. It is only after save and relaunch that a fetch request fails to traverse the hierarchy. Therefore, I can only conclude that it is the storage of the inheritance that is the problem. Let's recap why: - Both entities can be created, inserted into the context, and viewed, so the model is working - Both entities can be fetched with a single request, so the inheritance is working - I can confirm that the files are being stored separately and objects are going into their appropriate stores, so saving is working - Launching the app with either entity set for the request works, so retrieval from the store is working - This also means that traversing different stores with the request is working - By using a single store instead of multiple, the problem goes away completely, so creating, storing, fetching, viewing etc is working correctly. This leaves only one culprit (to my mind): the inheritance I'm setting with setSubentities: is effective only for objects creating during the session. Either objects/entities are being stored stripped of the inheritance info, or entity inheritance as defined programmatically only applies to new instances, or both. Either of these is unacceptable. Either it's a bug or I am way, way off course. I have been at this every which way for two days; any insight is greatly appreciated. The current workaround - just using a single store - works completely, except it won't be future-proof in the event that I remove one of the models from the app etc. It also boggles the mind because I can't see why you would have all this infrastructure for storing across multiple stores and for setting affected stores in fetch requests if it by core definition (of setSubentities:) doesn't work.

Job conditions conflicting with personal principles on software-development - how much is too much?

- by Baelnorn

Sorry for the incoming wall'o'text (and for my probably bad English) but I just need to get this off somehow. I also accept that this question will be probably closed as subjective and argumentative, but I need to know one thing: "how much BS are programmers supposed to put up with before breaking?" My background I'm 27 years old and have a B.Sc. in Computer engineering with a graduation grade of 1.8 from a university of applied science. I went looking for a job right after graduation. I got three offers right away, with two offers paying vastly more than the last one, but that last one seemed more interesting so I went for that. My situation I've been working for the company now for 17 months now, but it feels like a drag more and more each day. Primarily because the company (which has only 5 other developers but me, and of these I work with 4) turned out to be pretty much the anti-thesis of what I expected (and was taught in university) from a modern software company. I agreed to accept less than half of the usual payment appropriate for my qualification for the first year because I was promised a trainee program. However, the trainee program turned out to be "here you got a computer, there's some links on the stuff we use, and now do what you colleagues tell you". Further, during my whole time there (trainee or not) I haven't been given the grace of even a single code-review - apparently nobody's interested in my work as long as it "just works". I was told in the job interview that "Microsoft technology played a central role in the company" yet I've been slowly eroding my congnitive functions with Flex/Actionscript/Cairngorm ever since I started (despite having applied as a C#/.NET developer). Actually, the company's primary projects are based on Java/XSLT and Flex/Actionscript (with some SAP/ABAP stuff here and there but I'm not involved in that) and they've been working on these before I even applied. Having had no experience either with that particular technology nor the framework nor the field (RIA) nor in developing business scale applications I obviously made several mistakes. However, my boss told me that he let me make those mistakes (which ate at least 2 months of development time on their own) on purpose to provide some "learning experience". Even when I was still a trainee I was already tasked with working on a business-critical application. On my own. Without supervision. Without code-reviews. My boss thinks agile methods are a waste of time/money and deems putting more than one developer on any project not efficient. Documentation is not necessary and each developer should only document what he himself needs for his work. Recently he wanted us to do bug tracking with Excel and Email instead of using an already existing Bugzilla, overriding an unanimous decision made by all developers and testers involved in the process - only after another senior developer had another hour-long private discussion with him he agreed to let us use the bugtracker. Project management is basically not present, there are only a few Excel sheets floating around where the senior developer lists some things (not all, mind you) with a time estimate ranging from days to months, trying to at least somehow organize the whole mess. A development process is also basically not present, each developer just works on his own however he wants. There are not even coding conventions in the company. Testing is done manually with a single tester (sometimes two testers) per project because automated testing wasn't given the least thought when the whole project was started. I guess it's not a big surprise when I say that each developer also has his own share of hundreds of overhours (which are, of course, unpaid). Each developer is tasked with working on his own project(s) which in turn leads to a very extensive knowledge monopolization - if one developer was to have an accident or become ill there would be absolutely no one who could even hope to do his work. Considering that each developer has his own business-critical application to work on, I guess that's a pretty bad situation. I've been trying to change things for the better. I tried to introduce a development process, but my first attempt was pretty much shot down by my boss with "I don't want to discuss agile methods". After that I put together a process that at least resembled how most of the developers were already working and then include stuff like automated (or at least organized) testing, coding conventions, etc. However, this was also shot down because it wasn't "simple" enought to be shown on a business slide (actually, I wasn't even given the 15 minutes I'd have needed to present the process in the meeting). My problem I can't stand working there any longer. Seriously, I consider to resign on monday, which still leaves me with 3 months to work there due to the cancelation period. My primary goal since I started studying computer science was being a good computer scientist, working with modern technologies and adhering to modern and proven principles and methods. However, the company I'm working for seems to make that impossible. Some days I feel as if was living in a perverted real-life version of the Dilbert comics. My question Am I overreacting? Is this the reality each graduate from university has to face? Should I betray my sound principles and just accept these working conditions? Or should I gtfo of there? What's the opinion of other developers on this matter. Would you put up with all that stuff?

Prim's MST algorithm implementation with Java

- by user1290164

I'm trying to write a program that'll find the MST of a given undirected weighted graph with Kruskal's and Prim's algorithms. I've successfully implemented Kruskal's algorithm in the program, but I'm having trouble with Prim's. To be more precise, I can't figure out how to actually build the Prim function so that it'll iterate through all the vertices in the graph. I'm getting some IndexOutOfBoundsException errors during program execution. I'm not sure how much information is needed for others to get the idea of what I have done so far, but hopefully there won't be too much useless information. This is what I have so far: I have a Graph, Edge and a Vertex class. Vertex class mostly just an information storage that contains the name (number) of the vertex. Edge class can create a new Edge that has gets parameters (Vertex start, Vertex end, int edgeWeight). The class has methods to return the usual info like start vertex, end vertex and the weight. Graph class reads data from a text file and adds new Edges to an ArrayList. The text file also tells us how many vertecis the graph has, and that gets stored too. In the Graph class, I have a Prim() -method that's supposed to calculate the MST: public ArrayList<Edge> Prim(Graph G) { ArrayList<Edge> edges = G.graph; // Copies the ArrayList with all edges in it. ArrayList<Edge> MST = new ArrayList<Edge>(); Random rnd = new Random(); Vertex startingVertex = edges.get(rnd.nextInt(G.returnVertexCount())).returnStartingVertex(); // This is just to randomize the starting vertex. // This is supposed to be the main loop to find the MST, but this is probably horribly wrong.. while (MST.size() < returnVertexCount()) { Edge e = findClosestNeighbour(startingVertex); MST.add(e); visited.add(e.returnStartingVertex()); visited.add(e.returnEndingVertex()); edges.remove(e); } return MST; } The method findClosesNeighbour() looks like this: public Edge findClosestNeighbour(Vertex v) { ArrayList<Edge> neighbours = new ArrayList<Edge>(); ArrayList<Edge> edges = graph; for (int i = 0; i < edges.size() -1; ++i) { if (edges.get(i).endPoint() == s.returnVertexID() && !visited(edges.get(i).returnEndingVertex())) { neighbours.add(edges.get(i)); } } return neighbours.get(0); // This is the minimum weight edge in the list. } ArrayList<Vertex> visited and ArrayList<Edges> graph get constructed when creating a new graph. Visited() -method is simply a boolean check to see if ArrayList visited contains the Vertex we're thinking about moving to. I tested the findClosestNeighbour() independantly and it seemed to be working but if someone finds something wrong with it then that feedback is welcome also. Mainly though as I mentioned my problem is with actually building the main loop in the Prim() -method, and if there's any additional info needed I'm happy to provide it. Thank you. Edit: To clarify what my train of thought with the Prim() method is. What I want to do is first randomize the starting point in the graph. After that, I will find the closest neighbor to that starting point. Then we'll add the edge connecting those two points to the MST, and also add the vertices to the visited list for checking later, so that we won't form any loops in the graph. Here's the error that gets thrown: Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.rangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) at Graph.findClosestNeighbour(graph.java:203) at Graph.Prim(graph.java:179) at MST.main(MST.java:49) Line 203: return neighbour.get(0); in findClosestNeighbour() Line 179: Edge e = findClosestNeighbour(startingVertex); in Prim()

Sorting/Paginating/Filtering Complex Multi-AR Object Tables in Rails

- by Matt Rogish

I have a complex table pulled from a multi-ActiveRecord object array. This listing is a combined display of all of a particular user's "favorite" items (songs, messages, blog postings, whatever). Each of these items is a full-fledged AR object. My goal is to present the user with a simplified search, sort, and pagination interface. The user need not know that the Song has a singer, and that the Message has an author -- to the end user both entries in the table will be displayed as "User". Thus, the search box will simply be a dropdown list asking them which to search on (User name, created at, etc.). Internally, I would need to convert that to the appropriate object search, combine the results, and display. I can, separately, do pagination (mislav will_paginate), sorting, and filtering, but together I'm having some problems combining them. For example, if I paginate the combined list of items, the pagination plugin handles it just fine. It is not efficient since the pagination is happening in the app vs. the DB, but let's assume the intended use-case would indicate the vast majority of the users will have less than 30 favorited items and all other behavior, server capabilities, etc. indicates this will not be a bottleneck. However, if I wish to sort the list I cannot sort it via the pagination plugin because it relies on the assumption that the result set is derived from a single SQL query, and also that the field name is consistent throughout. Thus, I must sort the merged array via ruby, e.g. @items.sort_by{ |i| i.whatever } But, since the items do not share common names, I must first interrogate the object and then call the correct sort by. For example, if the user wishes to sort by user name, if the sorted object is a message, I sort by author but if the object is a song, I sort by singer. This is all very gross and feels quite un-ruby-like. This same problem comes into play with the filter. If the user filters on the "parent item" (the message's thread, the song's album), I must translate that to the appropriate collection object method. Also gross. This is not the exact set-up but is close enough. Note that this is a legacy app so changing it is quite difficult, although not impossible. Also, yes there is some DRY that can be done, but don't focus on the style or elegance of the following code. Style/elegance of the SOLUTION is important, however! :D models: class User < ActiveRecord::Base ... has_and_belongs_to_many :favorite_messages, :class_name => "Message" has_and_belongs_to_many :favorite_songs, :class_name => "Song" has_many :authored_messages, :class_name => "Message" has_many :sung_songs, :class_name => "Song" end class Message < ActiveRecord::Base has_and_belongs_to_many :favorite_messages belongs_to :author, :class_name => "User" belongs_to :thread end class Song < ActiveRecord::Base has_and_belongs_to_many :favorite_songs belongs_to :singer, :class_name => "User" belongs_to :album end controller: def show u = User.find 123 @items = Array.new @items << u.favorite_messages @items << u.favorite_songs # etc. etc. @items.flatten! @items = @items.sort_by{ |i| i.created_at } @items = @items.paginate :page => params[:page], :per_page => 20 end def search # Assume user is searching for username like 'Bob' u = User.find 123 @items = Array.new @items << u.favorite_messages.find( :all, :conditions => "LOWER( author ) LIKE LOWER('%bob%')" ) @items << u.favorite_songs.find( :all, :conditions => "LOWER( singer ) LIKE ... " ) # etc. etc. @items.flatten! @items = @items.sort_by{ |i| determine appropriate sorting based on user selection } @items = @items.paginate :page => params[:page], :per_page => 20 end view: #index.html.erb ... <table> <tr> <th>Title (sort ASC/DESC links)</th> <th>Created By (sort ASC/DESC links))</th> <th>Collection Title (sort ASC/DESC links)</th> <th>Created At (sort ASC/DESC links)</th> </tr> <% @items.each |item| do %> <%= render { :partial => "message", :locals => item } if item.is_a?

Getting a NullPointerException at seemingly random intervals, not sure why

- by Miles

I'm running an example from a Kinect library for Processing (http://www.shiffman.net/2010/11/14/kinect-and-processing/) and sometimes get a NullPointerException pointing to this line: int rawDepth = depth[offset]; The depth array is created in this line: int[] depth = kinect.getRawDepth(); I'm not exactly sure what a NullPointerException is, and much googling hasn't really helped. It seems odd to me that the code compiles 70% of the time and returns the error unpredictably. Could the hardware itself be affecting it? Here's the whole example if it helps: // Daniel Shiffman // Kinect Point Cloud example // http://www.shiffman.net // https://github.com/shiffman/libfreenect/tree/master/wrappers/java/processing import org.openkinect.*; import org.openkinect.processing.*; // Kinect Library object Kinect kinect; float a = 0; // Size of kinect image int w = 640; int h = 480; // We'll use a lookup table so that we don't have to repeat the math over and over float[] depthLookUp = new float[2048]; void setup() { size(800,600,P3D); kinect = new Kinect(this); kinect.start(); kinect.enableDepth(true); // We don't need the grayscale image in this example // so this makes it more efficient kinect.processDepthImage(false); // Lookup table for all possible depth values (0 - 2047) for (int i = 0; i < depthLookUp.length; i++) { depthLookUp[i] = rawDepthToMeters(i); } } void draw() { background(0); fill(255); textMode(SCREEN); text("Kinect FR: " + (int)kinect.getDepthFPS() + "\nProcessing FR: " + (int)frameRate,10,16); // Get the raw depth as array of integers int[] depth = kinect.getRawDepth(); // We're just going to calculate and draw every 4th pixel (equivalent of 160x120) int skip = 4; // Translate and rotate translate(width/2,height/2,-50); rotateY(a); for(int x=0; x<w; x+=skip) { for(int y=0; y<h; y+=skip) { int offset = x+y*w; // Convert kinect data to world xyz coordinate int rawDepth = depth[offset]; PVector v = depthToWorld(x,y,rawDepth); stroke(255); pushMatrix(); // Scale up by 200 float factor = 200; translate(v.x*factor,v.y*factor,factor-v.z*factor); // Draw a point point(0,0); popMatrix(); } } // Rotate a += 0.015f; } // These functions come from: http://graphics.stanford.edu/~mdfisher/Kinect.html float rawDepthToMeters(int depthValue) { if (depthValue < 2047) { return (float)(1.0 / ((double)(depthValue) * -0.0030711016 + 3.3309495161)); } return 0.0f; } PVector depthToWorld(int x, int y, int depthValue) { final double fx_d = 1.0 / 5.9421434211923247e+02; final double fy_d = 1.0 / 5.9104053696870778e+02; final double cx_d = 3.3930780975300314e+02; final double cy_d = 2.4273913761751615e+02; PVector result = new PVector(); double depth = depthLookUp[depthValue];//rawDepthToMeters(depthValue); result.x = (float)((x - cx_d) * depth * fx_d); result.y = (float)((y - cy_d) * depth * fy_d); result.z = (float)(depth); return result; } void stop() { kinect.quit(); super.stop(); } And here are the errors: processing.app.debug.RunnerException: NullPointerException at processing.app.Sketch.placeException(Sketch.java:1543) at processing.app.debug.Runner.findException(Runner.java:583) at processing.app.debug.Runner.reportException(Runner.java:558) at processing.app.debug.Runner.exception(Runner.java:498) at processing.app.debug.EventThread.exceptionEvent(EventThread.java:367) at processing.app.debug.EventThread.handleEvent(EventThread.java:255) at processing.app.debug.EventThread.run(EventThread.java:89) Exception in thread "Animation Thread" java.lang.NullPointerException at org.openkinect.processing.Kinect.enableDepth(Kinect.java:70) at PointCloud.setup(PointCloud.java:48) at processing.core.PApplet.handleDraw(PApplet.java:1583) at processing.core.PApplet.run(PApplet.java:1503) at java.lang.Thread.run(Thread.java:637)

Help needed with Javascript Variable Scope / OOP and Call Back Functions

- by gargantaun

I think this issue goes beyond typical variable scope and closure stuff, or maybe I'm an idiot. Here goes anyway... I'm creating a bunch of objects on the fly in a jQuery plugin. The object look something like this function WedgePath(canvas){ this.targetCanvas = canvas; this.label; this.logLabel = function(){ console.log(this.label) } } the jQuery plugin looks something like this (function($) { $.fn.myPlugin = function() { return $(this).each(function() { // Create Wedge Objects for(var i = 1; i <= 30; i++){ var newWedge = new WedgePath(canvas); newWedge.label = "my_wedge_"+i; globalFunction(i, newWedge]); } }); } })(jQuery); So... the plugin creates a bunch of wedgeObjects, then calls 'globalFunction' for each one, passing in the latest WedgePath instance. Global function looks like this. function globalFunction(indicator_id, pWedge){ var targetWedge = pWedge; targetWedge.logLabel(); } What happens next is that the console logs each wedges label correctly. However, I need a bit more complexity inside globalFunction. So it actually looks like this... function globalFunction(indicator_id, pWedge){ var targetWedge = pWedge; someSql = "SELECT * FROM myTable WHERE id = ?"; dbInterface.executeSql(someSql, [indicator_id], function(transaction, result){ targetWedge.logLabel(); }) } There's a lot going on here so i'll explain. I'm using client side database storage (WebSQL i call it). 'dbInterface' an instance of a simple javascript object I created which handles the basics of interacting with a client side database [shown at the end of this question]. the executeSql method takes up to 4 arguments The SQL String an optional arguments array an optional onSuccess handler an optional onError handler (not used in this example) What I need to happen is: When the WebSQL query has completed, it takes some of that data and manipulates some attribute of a particular wedge. But, when I call 'logLabel' on an instance of WedgePath inside the onSuccess handler, I get the label of the very last instance of WedgePath that was created way back in the plugin code. Now I suspect that the problem lies in the var newWedge = new WedgePath(canvas); line. So I tried pushing each newWedge into an array, which I thought would prevent that line from replacing or overwriting the WedgePath instance at every iteration... wedgeArray = []; // Inside the plugin... for(var i = 1; i <= 30; i++){ var newWedge = new WedgePath(canvas); newWedge.label = "my_wedge_"+i; wedgeArray.push(newWedge); } for(var i = 0; i < wedgeArray.length; i++){ wedgeArray[i].logLabel() } But again, I get the last instance of WedgePath to be created. This is driving me nuts. I apologise for the length of the question but I wanted to be as clear as possible. END ============================================================== Also, here's the code for dbInterface object should it be relevant. function DatabaseInterface(db){ var DB = db; this.sql = function(sql, arr, pSuccessHandler, pErrorHandler){ successHandler = (pSuccessHandler) ? pSuccessHandler : this.defaultSuccessHandler; errorHandler = (pErrorHandler) ? pErrorHandler : this.defaultErrorHandler; DB.transaction(function(tx){ if(!arr || arr.length == 0){ tx.executeSql(sql, [], successHandler, errorHandler); }else{ tx.executeSql(sql,arr, successHandler, errorHandler) } }); } // ---------------------------------------------------------------- // A Default Error Handler // ---------------------------------------------------------------- this.defaultErrorHandler = function(transaction, error){ // error.message is a human-readable string. // error.code is a numeric error code console.log('WebSQL Error: '+error.message+' (Code '+error.code+')'); // Handle errors here var we_think_this_error_is_fatal = true; if (we_think_this_error_is_fatal) return true; return false; } // ---------------------------------------------------------------- // A Default Success Handler // This doesn't do anything except log a success message // ---------------------------------------------------------------- this.defaultSuccessHandler = function(transaction, results) { console.log("WebSQL Success. Default success handler. No action taken."); } }

New hire expectations... (Am I being unreasonable?)

- by user295841

I work for a very small custom software shop. We currently consist me and my boss. My boss is an old FoxPro DOS developer and OOP makes him uncomfortable. He is planning on taking a back seat in the next few years to hopefully enjoy a “partial retirement”. I will be taking over the day to day operations and we are now desperately looking for more help. We tried Monster.com, Dice.com, and others a few years ago when we started our search. We had no success. We have tried outsourcing overseas (total disaster), hiring kids right out of college (mostly a disaster but that’s where I came from), interns (good for them, not so good for us) and hiring laid off “experienced” developers (there was a reason they were laid off). I have heard hiring practices discussed on podcasts, blogs, etc... and have tried a few. The “Fizz Buzz” test was a good one. One kid looked physically ill before he finally gave up. I think my problem is that I have grown so much as a developer since I started here that I now have a high standard. I hear/read very intelligent people podcasts and blogs and I know that there are lots of people out there that can do the job. I don’t want to settle for less than a “good” developer. Perhaps my expectations are unreasonable. I expect any good developer (entry level or experienced) to be billable (at least paying their own wage) in under one month. I expect any good developer to be able to be productive (at least dangerous) in any language or technology with only a few days of research/training. I expect any good developer to be able to take a project from initial customer request to completion with little or no help from others. Am I being unreasonable? What constitutes a valuable developer? What should be expected of an entry level developer? What should be expected of an experienced developer? I realize that everyone is different but there has to be some sort of expectations standard, right? I have been giving the test project below to potential canidates to weed them out. Good idea? Too much? Too little? Please let me know what you think. Thanks.

Difficulty creating a paging function with MySQL and ColdFusion

- by Mel

I'm trying to create pagination for search results using MySQL and ColdFusion. My intention is to only retrieve the queries that can be displayed on a single page, thus making the process efficient. I tried using two queries in my function, but I could not return two variables to the cfinvoke. The following code does not paginate, but it displays the result search results using a CFC:  <cfparam name="variables.searchResponse" default=""> <cfparam name="URL.titleName" default=""> <cfparam name="URL.genreID" default=""> <cfparam name="URL.platformID" default="">  <cfif StructKeyExists(URL, "searchQuery") AND (Len(Trim(URL.titleName)) LTE 2 AND Len(URL.genreID) IS 0 AND Len(URL.platformID) IS 0)> <cfset variables.searchResponse = "invalidString"> <cfelseif StructKeyExists(URL, "searchQuery")> <cfinvoke component="gz.cfcomp.test" method="searchGames" returnvariable="resultData" argumentcollection="#URL#"> <cfset variables.searchResponse = "hasResult"> </cfif> <cfif searchResponse EQ "hasResult" AND resultData.RecordCount EQ 0> <cfset variables.searchResponse = "noResult"> </cfif> Using this logic, I can display what I need to display on the page: <cfif searchResponse EQ "invalidString"> <cfoutput>Invalid search</cfoutput> </cfif> <cfif searchResponse EQ "noResult"> <cfoutput>No results found</cfoutput> </cfif> <cfif searchResponse EQ "hasResult"> <cfoutput>Display Results</cfoutput> </cfif> If I were executing the queries on the same page, it would be easy to follow the many tutorials out there. But the queries are executing in a function. Displaying the data is easy, but paginating it has become a nightmare for me. Here is my function: <cffunction name="searchGames" access="public" output="false"> <cfargument name="titleName" required="no" type="string"> <cfargument name="genreID" required="no" type="string"> <cfargument name="platformID" required="no" type="string">  <cfset var resultData = "">  <cfquery name="resultData" datasource="myDSN"> SELECT *  WHERE  </cfquery>  <cfreturn resultData> </cffunction> To paginate, I thought about modifying my function to the following (a new query using a count statement):  <cfset var resultCount = "">  <cfquery name="resultCount" datasource="myDSN"> SELECT COUNT(gameID) AS rowsFound FROM GAMES  WHERE  </cfquery>  <cfreturn resultCount> Then I figured if there is a result to return, I would execute a nested query and create the pagination variables: <cfif resultCount.rowsFound GTE 0> <cfparam name="pageNumber" default="1"> <cfset var recordsPerPage = 5> <cfset var numberOfPages = Int(resultCount.RecordCount / recordsPerPage)> <cfset var recordsToSkip = pageNumber * recordsPerPage - recordsPerPage>  <cfset var resultData = ""> <cfquery name="resultData" datasource="myDSN">  </cfquery>  <cfreturn resultData> </cffunction> I figured I would return two variables: resultCount and resultData. I would use #resultCount# to build my pagination, and #resultData# to display the output. The problem is I can't return two variables in the same cfinvoke tag. Any ideas of how to approach the the right way? I'm totally lost as to the logic I need to follow.

Hibernate without primary keys generated by db?

- by Michael Jones

I'm building a data warehouse and want to use InfiniDB as the storage engine. However, it doesn't allow primary keys or foreign key constraints (or any constraints for that matter). Hibernate complains "The database returned no natively generated identity value" when I perform an insert. Each table is relational, and contains a unique integer column that was previously used as the primary key - I want to keep that, but just not have the constraint in the db that the column is the primary key. I'm assuming the problem is that Hibernate expects the db to return a generated key. Is it possible to override this behaviour so I can set the primary key field's value myself and keep Hibernate happy? -- edit -- Two of the mappings are as follows: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  <hibernate-mapping> <class name="com.example.project.Visitor" table="visitor" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <property name="firstSeen" type="timestamp"> <column name="first_seen" length="19" /> </property> <property name="lastSeen" type="timestamp"> <column name="last_seen" length="19" /> </property> <property name="sessionId" type="string"> <column name="session_id" length="26" unique="true" /> </property> <property name="userId" type="java.lang.Long"> <column name="user_id" /> </property> <set name="visits" inverse="true"> <key> <column name="visitor_id" /> </key> <one-to-many class="com.example.project.Visit" /> </set> </class> </hibernate-mapping> and: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  <hibernate-mapping> <class name="com.example.project.Visit" table="visit" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <many-to-one name="visitor" class="com.example.project.Visitor" fetch="join" cascade="all"> <column name="visitor_id" /> </many-to-one> <property name="visitId" type="string"> <column name="visit_id" length="20" unique="true" /> </property> <property name="startTime" type="timestamp"> <column name="start_time" length="19" /> </property> <property name="endTime" type="timestamp"> <column name="end_time" length="19" /> </property> <property name="userAgent" type="string"> <column name="user_agent" length="65535" /> </property> <set name="pageViews" inverse="true"> <key> <column name="visit_id" /> </key> <one-to-many class="com.example.project.PageView" /> </set> </class> </hibernate-mapping>

Using C# to detect whether a filename character is considered international

- by Morten Mertner

I've written a small console application (source below) to locate and optionally rename files containing international characters, as they are a source of constant pain with most source control systems (some background on this below). The code I'm using has a simple dictionary with characters to look for and replace (and nukes every other character that uses more than one byte of storage), but it feels very hackish. What's the right way to (a) find out whether a character is international? and (b) what the best ASCII substitution character would be? Let me provide some background information on why this is needed. It so happens that the danish Å character has two different encodings in UTF-8, both representing the same symbol. These are known as NFC and NFD encodings. Windows and Linux will create NFC encoding by default but respect whatever encoding it is given. Mac will convert all names (when saving to a HFS+ partition) to NFD and therefore returns a different byte stream for the name of a file created on Windows. This effectively breaks Subversion, Git and lots of other utilities that don't care to properly handle this scenario. I'm currently evaluating Mercurial, which turns out to be even worse at handling international characters.. being fairly tired of these problems, either source control or the international character would have to go, and so here we are. My current implementation: public class Checker { private Dictionary<char, string> internationals = new Dictionary<char, string>(); private List<char> keep = new List<char>(); private List<char> seen = new List<char>(); public Checker() { internationals.Add( 'æ', "ae" ); internationals.Add( 'ø', "oe" ); internationals.Add( 'å', "aa" ); internationals.Add( 'Æ', "Ae" ); internationals.Add( 'Ø', "Oe" ); internationals.Add( 'Å', "Aa" ); internationals.Add( 'ö', "o" ); internationals.Add( 'ü', "u" ); internationals.Add( 'ä', "a" ); internationals.Add( 'é', "e" ); internationals.Add( 'è', "e" ); internationals.Add( 'ê', "e" ); internationals.Add( '¦', "" ); internationals.Add( 'Ã', "" ); internationals.Add( '©', "" ); internationals.Add( ' ', "" ); internationals.Add( '§', "" ); internationals.Add( '¡', "" ); internationals.Add( '³', "" ); internationals.Add( '', "" ); internationals.Add( 'º', "" ); internationals.Add( '«', "-" ); internationals.Add( '»', "-" ); internationals.Add( '´', "'" ); internationals.Add( '`', "'" ); internationals.Add( '"', "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 147 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 148 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 153 } )[ 0 ], "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 166 } )[ 0 ], "." ); keep.Add( '-' ); keep.Add( '=' ); keep.Add( '\'' ); keep.Add( '.' ); } public bool IsInternationalCharacter( char c ) { var s = c.ToString(); byte[] bytes = Encoding.UTF8.GetBytes( s ); if( bytes.Length > 1 && ! internationals.ContainsKey( c ) && ! seen.Contains( c ) ) { Console.WriteLine( "X '{0}' ({1})", c, string.Join( ",", bytes ) ); seen.Add( c ); if( ! keep.Contains( c ) ) { internationals[ c ] = ""; } } return internationals.ContainsKey( c ); } public bool HasInternationalCharactersInName( string name, out string safeName ) { StringBuilder sb = new StringBuilder(); Array.ForEach( name.ToCharArray(), c => sb.Append( IsInternationalCharacter( c ) ? internationals[ c ] : c.ToString() ) ); int length = sb.Length; sb.Replace( " ", " " ); while( sb.Length != length ) { sb.Replace( " ", " " ); } safeName = sb.ToString().Trim(); string namePart = Path.GetFileNameWithoutExtension( safeName ); if( namePart.EndsWith( "." ) ) safeName = namePart.Substring( 0, namePart.Length - 1 ) + Path.GetExtension( safeName ); return name != safeName; } } And this would be invoked like this: FileInfo file = new File( "Århus.txt" ); string safeName; if( checker.HasInternationalCharactersInName( file.Name, out safeName ) ) { // rename file }

CSS Containers and Framing

- by CaffeineAddiction

I am attempting to code a dynamic object for use in an unordered list. I have a mock up of the HTML here: <ul class='Main'> <li class='Node'> <span class='Node_Light'> </span> <span class='Node_Control'> <span class='Ctrl_Name'> <span class='CtrlN_Text'>Random Name</span> <span class='CtrlN_Edit'>[%]</span> </span><br/> <span class='Ctrl_ID'>ff:ff:ff:ff:ff:ff</span><br/> <span class='Ctrl_Buttons'> <span class='CBttn_On'>[%]</span> <span class='CBttn_Off'>[%]</span> <span class='CBttn_Blink'>[%]</span> <span class='CBttn_Config'>[%]</span> <span class='CBttn_Graph'>[%]</span> </span> </span> <span class='Node_Data'> <span class='ND_Sens0'> <span class='Sens_Lable'>temp:</span> <span class='Sens_Data'>72</span> <span class='Sens_Units'>°F</span> </span><br/> <span class='ND_Sens1'> <span class='Sens_Lable'>Sens1:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens2'> <span class='Sens_Lable'>Sens2:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens3'> <span class='Sens_Lable'>Sens3:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens4'> <span class='Sens_Lable'>Sens4:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span> </span> </li> </ul> and I am attempting to wrangle this HTML into something like: My first problem was that the 3x Outer elements would stack vertically instead of horizontally ... I solved this with the following CSS, but it doesnt feel like the right solution: ul { list-style-type: none; padding:0; margin:0; } .Node { } .Node_Light { height:6em; width:2em; position:absolute; border-style:solid; border-width:1px; } .Node_Control { height:6em; width:15em; position:absolute; left:2.55em; border-style:solid; border-width:1px; } .Node_Data { height:6em; width:6em; position:absolute; left:17.6em; border-style:solid; border-width:1px; } One thought was to use a table, but I dont think that is the correct solution either. Ideas? I would like to have the content dynamically resize on page resize and am not opposed to doing it all via JavaScript, but I have a feeling it would be more efficient to do it via CSS ... I just dont know where to begin.

Android Video Camera : still picture

- by Alex

I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work. Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); If I use this line of code, after press the recording button, the camera is freezed, I mean, the picture is still. Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); BTW, when I use $Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); to capture a picture, it works fine. The java file is as follows: package com.camera.picture; import java.io.File; import java.text.SimpleDateFormat; import java.util.Date; import android.app.Activity; import android.content.ContentValues; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast; import android.widget.VideoView; public class PictureCameraActivity extends Activity { private static final int IMAGE_CAPTURE = 0; private static final int VIDEO_CAPTURE = 1; private Button startBtn; private Button videoBtn; private Uri imageUri; private Uri videoUri; private ImageView imageView; private VideoView videoView; /** Called when the activity is first created. * sets the content and gets the references to * the basic widgets on the screen like * {@code Button} or {@link ImageView} */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView)findViewById(R.id.img); videoView = (VideoView)findViewById(R.id.videoView); startBtn = (Button) findViewById(R.id.startBtn); startBtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { startCamera(); } }); videoBtn = (Button) findViewById(R.id.videoBtn); videoBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startVideoCamera(); } }); } public void startCamera() { Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testphoto.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera"); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); imageUri = getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, IMAGE_CAPTURE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == IMAGE_CAPTURE) { if (resultCode == RESULT_OK){ Log.d("ANDROID_CAMERA","Picture taken!!!"); imageView.setImageURI(imageUri); } } if (requestCode == VIDEO_CAPTURE) { if (resultCode == RESULT_OK) { Log.d("ANDROID_CAMERA","Video taken!!!"); Toast.makeText(this, "Video saved to:\n" + data.getData(), Toast.LENGTH_LONG).show(); videoView.setVideoURI(videoUri); } } } private void startVideoCamera() { // TODO Auto-generated method stub //create new Intent Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testvideo.mp4"; ContentValues values = new ContentValues(); values.put(MediaStore.Video.Media.TITLE, fileName); values.put(MediaStore.Video.Media.DESCRIPTION, "Video captured by camera"); values.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4"); videoUri = getContentResolver().insert( MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); //Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // start the Video Capture Intent startActivityForResult(intent, VIDEO_CAPTURE); } private static File getOutputMediaFile() { // TODO Auto-generated method stub // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this.

Changing multiple objects with a new class name using Jquery

- by liquilife

I'd like to click on a trigger and show a specific image. There are multiple triggers which would show a specific image related to it within a set. There are 4 sets The challenge for me is toggling the other images to hide only in this 'set' when one of these triggers are clicked, as there can only be one image showing at a time in each set. Here is the HTML I've put together thus far:  <div class="materials"> <a href="javascript:;" id="shirtgrey"><img src="/grey_shirt.png" height="122" width="122" /></a> <a href="javascript:;" id="shirtred"><img src="red_shirt.png" height="122" width="122" /></a> <a href="javascript:;" id="shirtblue"><img src="hblue_shirt.png" height="122" width="122" /></a> <a href="javascript:;" id="shirtgreen"><img src="green_shirt.png" height="122" width="122" /></a> </div> <div class="collars"> <a href="javascript:;" id="collargrey"><img src="grey_collar.png" height="122" width="122" /></a> <a href="javascript:;" id="collarred"><img src="red_collar.png" height="122" width="122" /></a> <a href="javascript:;" id="collarblue"><img src="blue_collar.png" height="122" width="122" /></a> <a href="javascript:;" id="collargreen"><img src="green_collar.png" height="122" width="122" /></a> </div> <div class="cuffs"> <a href="javascript:;" id="cuffgrey"><img src="grey_cuff.png" height="122" width="122" /></a> <a href="javascript:;" id="cuffred"><img src="red_cuff.png" height="122" width="122" /></a> <a href="javascript:;" id="cuffblue"><img src="blue_cuff.png" height="122" width="122" /></a> <a href="javascript:;" id="cuffgreen"><img src="/green_cuff.png" height="122" width="122" /></a> </div> <div class="pockets"> <a href="javascript:;" id="pocketgrey"><img src="grey_pocket.png" height="122" width="122" /></a> <a href="javascript:;" id="pocketred"><img src=".png" height="122" width="122" /></a> <a href="javascript:;" id="pocketblue"><img src="blue_pocket.png" height="122" width="122" /></a> <a href="javascript:;" id="pocketgreen"><img src="green_pocket.png" height="122" width="122" /></a> </div>  <div class="selectionimg"> <div class="selectShirt"> <img src="grey_shirt.png" height="250" width="250" class="selectShirtGrey show" /> <img src="red_shirt.png" height="250" width="250" class="selectShirtRed hide" /> <img src="blue_shirt.png" height="250" width="250" class="selectShirtBlue hide" /> <img src="green_shirt.png" height="250" width="250" class="selectShirtGreen hide" /> </div> <div class="selectCollar"> <img src="grey_collar.png" height="250" width="250" class="selectCollarGrey show" /> <img src="red_collar.png" height="250" width="250" class="selectCollarRed hide" /> <img src="blue_collar.png" height="250" width="250" class="selectCollarBlue hide" /> <img src="green_collar.png" height="250" width="250" class="selectCollarGreen hide" /> </div> <div class="selectCuff"> <img src="grey_cuff.png" height="250" width="250" class="selectCuffGrey show" /> <img src="red_cuff.png" height="250" width="250" class="selectCuffRed hide" /> <img src="blue_cuff.png" height="250" width="250" class="selectCuffBlue hide" /> <img src="green_cuff.png" height="250" width="250" class="selectCuffGreen hide" /> </div> <div class="selectPocket"> <img src="grey_pocket.png" height="250" width="250" class="selectPocketGrey show" /> <img src="hred_pocket.png" height="250" width="250" class="selectPocketRed hide" /> <img src="blue_pocket.png" height="250" width="250" class="selectPocketBlue hide" /> <img src="green_pocket.png" height="250" width="250" class="selectPocketGreen hide" /> </div> </div> How can jQuery be used to change a class of an image to "show" and ensure that all other images in that same div are set to a class of "hide"? First time posting here. I'm very efficient with HTML and CSS and have a basic understanding of jQuery. I'm learning and this just seems a little bit beyond my abilities at the moment. I hope this all makes sense. Thanks for any help.

Simple prime number program - Weird issue with threads C#

- by Para

Hi! This is my code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; namespace FirePrime { class Program { static bool[] ThreadsFinished; static bool[] nums; static bool AllThreadsFinished() { bool allThreadsFinished = false; foreach (var threadFinished in ThreadsFinished) { allThreadsFinished &= threadFinished; } return allThreadsFinished; } static bool isPrime(int n) { if (n < 2) { return false; } if (n == 2) { return true; } if (n % 2 == 0) { return false; } int d = 3; while (d * d <= n) { if (n % d == 0) { return false; } d += 2; } return true; } static void MarkPrimes(int startNumber,int stopNumber,int ThreadNr) { for (int j = startNumber; j < stopNumber; j++) nums[j] = isPrime(j); lock (typeof(Program)) { ThreadsFinished[ThreadNr] = true; } } static void Main(string[] args) { int nrNums = 100; int nrThreads = 10; //var threadStartNums = new List<int>(); ThreadsFinished = new bool[nrThreads]; nums = new bool[nrNums]; //var nums = new List<bool>(); nums[0] = false; nums[1] = false; for(int i=2;i<nrNums;i++) nums[i] = true; int interval = (int)(nrNums / nrThreads); //threadStartNums.Add(2); //int aux = firstStartNum; //int i = 2; //while (aux < interval) //{ // aux = interval*i; // i=i+1; // threadStartNums.Add(aux); //} int startNum = 0; for (int i = 0; i < nrThreads; i++) { var _thread = new System.Threading.Thread(() => MarkPrimes(startNum, Math.Min(startNum + interval, nrNums), i)); startNum = startNum + interval; //set the thread to run in the background _thread.IsBackground = true; //start our thread _thread.Start(); } while (!AllThreadsFinished()) { Thread.Sleep(1); } for (int i = 0; i < nrNums; i++) if(nums[i]) Console.WriteLine(i); } } } This should be a pretty simple program that is supposed to find and output the first nrNums prime numbers using nrThreads threads working in parallel. So, I just split nrNums into nrThreads equal chunks (well, the last one won't be equal; if nrThreads doesn't divide by nrNums, it will also contain the remainder, of course). I start nrThreads threads. They all test each number in their respective chunk and see if it is prime or not; they mark everything out in a bool array that keeps a tab on all the primes. The threads all turn a specific element in another boolean array ThreadsFinished to true when they finish. Now the weird part begins: The threads never all end. If I debug, I find that ThreadNr is not what I assign to it in the loop but another value. I guess this is normal since the threads execute afterwards and the counter (the variable i) is already increased by then but I cannot understand how to make the code be right. Can anyone help? Thank you in advance. P.S.: I know the algorithm is not very efficient; I am aiming at a solution using the sieve of Eratosthenes also with x given threads. But for now I can't even get this one to work and I haven't found any examples of any implementations of that algorithm anywhere in a language that I can understand.

Re-opening closed dialog puts it in the start position after moving it

- by semmelbroesel

I'm using multiple instances of the JQuery-UI dialog along with draggable and resizable. Whenever I drag or resize one of the dialog boxes, the position and dimensions of the current box are saved to a database and then loaded the next time the page opens. This is working well. However, when I close a dialog box and re-open it using a button, jQuery sets the position of the box back to its original location in the center of the screen. Furthermore, I use a show effect to slide the box off to the left on closing and in from the left on re-opening. I found two ways to update its position when the slide in animation is done, however, it still slides into the center of the screen, and I have yet to find a way to get it to slide in towards the location it is supposed to have. Here are the parts of the code that play a part in this: $('.box').dialog({ closeOnEscape: false, hide: { effect: "drop", direction: 'left' }, beforeClose: function (evt, ui){ var $this = $(this); SavePos($this); // saves the dimensions to db }, dragStop: function() { var $this = $(this); SavePos($this); }, resizeStop: function() { var $this = $(this); SavePos($this); }, open: function() { var $this = $(this); $this.dialog('option', { show: { effect: "drop", direction: 'left'} } ); if (init) // meaning only load this code when the page has finished initializing { // tried it both ways - set the position before and after the effect - no success UpdatePos($this.attr('id')); // I tried this section with promise() and effect / complete - I found no difference $this.parent().promise().done(function() { UpdatePos($this.attr('id')); }); } } }); function UpdatePos(key) { // boxpos is an object holding the position for each box by the box's id var $this = $('#' + key); //console.log('updating pos for box ' + boxid); if ($this && $this.hasClass('ui-dialog-content')) { //console.log($this.dialog('widget').css('left')); $this.dialog('option', { width: boxpos[key].width, height: boxpos[key].height }); $this.dialog('widget').css({ left: boxpos[key].left + 'px', top: boxpos[key].top + 'px' }); //console.log('finished updating pos'); //console.log($this.dialog('widget').css('left')); } } The button that re-opens the box has this code on it to make that happen: var $box = $('#boxid'); if ($box) { if ($box.dialog('isOpen')) { $box.dialog('moveToTop'); } else { $box.dialog("open") } } I don't know what jQuery-UI does to the box as it hides it (other than display:none) or to make it slide in, so maybe there's something I'm missing here that might help... Basically, I need JQuery to remember the box' position and put the box back into that location when it is re-opened. It took me days to make it this far, but this is one obstacle I have yet to overcome. Maybe there's a different way I can re-open the box? Thanks! EDIT: Forgot - this issue ONLY happens when I use my UpdatePos function to set the location of a box (i.e. on page load). When I drag a box with my mouse, close it, and re-open it, everything works. So I'm guessing there's one more storage location for the box' position that I'm missing here... EDIT2: After more messing with it, my code for debugging now looks like this: open: function() { var $this = $(this); console.log('box open'); console.log($this.dialog('widget').position()); // { top=0, left=-78.5} console.log($this.dialog('widget').css('left')); $this.dialog('option', { show: { effect: "drop", direction: 'left'} } ); if (init) { UpdatePos($this.attr('id')); $this.parent().promise().done(function() { console.log($this.dialog('widget').position()); // { top=313, left=641.5} console.log($this.dialog('widget').css('left')); UpdatePos($this.attr('id')); console.log($this.dialog('widget').position()); // { top=121, left=107} console.log($this.dialog('widget').css('left')); }); } The results I'm getting are: box open Object { top=0, left=-78.5} -78.5px Object { top=313, left=641.5} 641.5px Object { top=121, left=107} 107px So looks to me as if the widget is being moved off screen (left=-78.5) and then moved for the animation, and then my code moves it into the location that it should be in (121/107). The position() results for $box.position() or $box.dialog().position() do not change during this debugging section. Maybe this will help someone here - I'm still out of ideas here... ... and I just discovered that when I drag the item around myself, then close and re-open it, it is very unpredictable. Sometimes, it will end up in the correct location horizontally, but not vertically. Sometimes, it will end up back in the center of the screen...

C#: Searching through arrays

- by Jonathan Oberhaus

I have a dvd app that stores dvds and blu-rays, I want to search the arrays by director. Below is the code for the inventory class I have seen many different ways to do this. There seems to be some debate as the best/most efficient way to accomplish this, any suggestions? Blockquote namespace MovieInventoryApplication { class Inventory { public Bluray[] BlurayMovies; public DVD[] DVDMovies; private int blurayCount; private int dvdCount; public Inventory() { BlurayMovies = new Bluray[5]; DVDMovies = new DVD[5]; blurayCount = 0; dvdCount = 0; } public void AddBluray() { String strTitle; int intReleaseYear; int intRunningTimeMinutes; String strDirector; int intPrice; int intRegionCode; try { Console.Write("Enter a title: "); strTitle = Console.ReadLine(); Console.Write("Enter a release year: "); intReleaseYear = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter the running time in minutes: "); intRunningTimeMinutes = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter the directors name: "); strDirector = Console.ReadLine(); Console.Write("Enter a rental price: "); intPrice = Convert.ToInt32(Console.ReadLine()); BlurayMovies[blurayCount] = new Bluray(strTitle, intReleaseYear, intRunningTimeMinutes, strDirector, intPrice); blurayCount++; Console.Write("Enter the DVD region code: "); intRegionCode = Convert.ToInt32(Console.ReadLine()); DVDMovies[dvdCount] = new DVD(strTitle, intReleaseYear, intRunningTimeMinutes, strDirector, intPrice, intRegionCode); dvdCount++; } catch (FormatException FormatException) { Console.WriteLine(FormatException.Message); Console.WriteLine("Please enter a number in this field."); } } public void AddDVD() { String strTitle; int intReleaseYear; int intRunningTimeMinutes; String strDirector; int intPrice; int intRegionCode; try { Console.Write("Enter a title: "); strTitle = Console.ReadLine(); Console.Write("Enter a release year: "); intReleaseYear = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter the running time in minutes: "); intRunningTimeMinutes = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter the directors name: "); strDirector = Console.ReadLine(); Console.Write("Enter a rental price: "); intPrice = Convert.ToInt32(Console.ReadLine()); Console.Write("Enter the region code: "); intRegionCode = Convert.ToInt32(Console.ReadLine()); DVDMovies[dvdCount] = new DVD(strTitle, intReleaseYear, intRunningTimeMinutes, strDirector, intPrice, intRegionCode); dvdCount++; } catch (FormatException FormatException) { Console.WriteLine(FormatException.Message); Console.WriteLine("Please enter a number in this field."); } } public void ListAllBluray() { int position = 0; while (BlurayMovies[position] != null) { Console.WriteLine(position + " " + BlurayMovies[position].strTitle); position++; } } public void ListAllDVD() { int position = 0; while (DVDMovies[position] != null) { //position + 1 + " " + Console.WriteLine(position + " " + DVDMovies[position].strTitle); position++; } } public void BlurayInfo(int position) { Console.WriteLine("Title: {0}", DVDMovies[position].strTitle); Console.WriteLine("Release Year: {0}", DVDMovies[position].intReleaseYear); Console.WriteLine("Running Time (Minutes): {0}", DVDMovies[position].intRunningTimeMinutes); Console.WriteLine("Director: {0}", DVDMovies[position].strDirector); Console.WriteLine("Price: {0}", DVDMovies[position].intPrice); } public void DVDInfo(int position) { Console.WriteLine("Title: {0}", DVDMovies[position].strTitle); Console.WriteLine("Release Year: {0}", DVDMovies[position].intReleaseYear); Console.WriteLine("Running Time (Minutes): {0}", DVDMovies[position].intRunningTimeMinutes); Console.WriteLine("Director: {0}", DVDMovies[position].strDirector); Console.WriteLine("Price: {0}", DVDMovies[position].intPrice); Console.WriteLine("Region Code: {0}", DVDMovies[position].intRegionCode); } } }

File Access problems with SLES 10 SP2 OES2 SP1

- by Blackhawk131

We have identified a couple of repeatable, demonstrable scenarios with unexplained rejected folder access on our servers for Mac users. Hopefully, this can be presented to Novell for a solution. What we did to demonstrate scenario 1; 1. setup a PC and Mac side-by-side 2. login to our server and open up to a central location on both Mac and PC 3. on the PC in that central location create a folder 4. on the Mac in that central location drag the created folder to the Mac desktop, this should work fine, no problem 5. on the PC rename that folder 6. on the Mac drag a file to that renamed folder, this should error with the following message; a. You cannot copy some of these items to the destination because their names are too long for the destination. Do you want to skip copying these items and continue copying the other items? b. Select skip, response is the filename is copied to the location with zero or small byte size. Try opening it and you get file is corrupted error message. What we did to demonstrate scenario 2; 1. setup a PC and Mac side-by-side 2. login to our server and open up to a central location on both Mac and PC 3. on the PC in that central location create a folder then create a subfolder 4. copy some content into the subfolder 5. on the Mac in that central location drag the created top level folder to the Mac desktop, this should work fine, no problem 6. on the PC rename that subfolder 7. on the Mac drag that top level folder to the Mac desktop, this should error on the Mac with the following; a. The operation cannot be completed because you do not have sufficient privileges for b. The operation cannot be completed because you do not have sufficient privileges for 8. on the Mac, if you open that subfolder you can see the file copied in step 4 above but, you can not open that file, you get the following message if you try; a. There was an error opening this document. You do not have permission to open this file. 9. on the PC drag some content into the top level folder 10. on the Mac you can open that file directly from the server or copy it locally, no problem, however-the subfolder is still corrupted or locked, whichever 11. on the PC rename the top level folder 12. on the Mac that same file just opened in step 10 above is now not accessible, get the following message; a. The document could not be opened. I have observed some variances in the above. For instance, a change on the PC side may take a moment before you can observer or act on the Mac side - kind of like the server is slow to respond. Also, the error message may vary. However, the key is once a folder, or subfolder, gets renamed by a PC, Mac problems commence. The solution is to create a new folder from a PC and copy the contents of the corrupted folder to the new folder and not rename the folder name. This has to be done on a PC because the corrupted folder is not accessible by a Mac user. Another problem that dovetails with the above is that we know certain characters are not allowed for PC folder or filenames. If a Mac user creates a folder with a slash in the file name, from the PC the user does not see that slash in the name. As soon as the PC user copies a file to that folder, the Mac user is locked from that folder. Will get the following error message; - Sorry, the operation could not be completed because an unexpected error occurred. - (Error code - 50) In addition to the above mentioned character issue with folders, the problem is more evil with filenames. If, for example, you create a file with a slash in the filename on a Mac and copy it to the server you will get the following error message; - You cannot copy some of these items to the destination because their names are too long for the destination. Do you want to skip copying these items and continue copying the other items? Select either Stop or Skip buttons. It does not matter which button is selected. The file name gets copied to the destination location at a reduced size. Depending on the file type, the icon associated with the file may or may not be present. Furthermore, if you open that file on the server you will get the following message; - Couldnt open the file. It may be corrupt or a file format that doesnt recognize. From the users perspective, if they are not observant of the icon or file size, they may disregard the error message and think their file has copied as intended. Only later do they discover the file is corrupt if they open that file. I want to make a note on this problem. It is the PC causing the issue. You can change folder and file names all day on a MAC and you don't have a problem as long as a character is not the issue. Once you change the file name or folder name from a PC the entire folder structure from that level down is corrupted. But it has to be resolved from a PC by creating a new folder and copying the contents to the new folder like stated above. Is something not configured correctly?
