• How can I sync three classes?

  - by TheMachineCharmer

  class Foo { Bar b; List<Foo> Neighbours; } class Bar { Spam s; List<Bar> Neighbours; } class Spam { List<string> Neighbours; } Each of these classes have AddNeighbour,RemoveNeighbour methods. User can add/remove Neighbours from any of the class at random. I want these three objects to be in sync. How can I do this?

• Is window.location.href = 'some_page.html' followed by search engines?

  - by Arkaaito

  Currently our website uses links to allow the user to change their locale. The problem with this is that you get a lot of random outlinks from each page on the site to... the same page, in other languages. When a search engine traverses this, it gets an excessively complex view of the site. We were going to change it to a form post to avoid this. However, it seems to me that we should just be able to change it to an onclick="window.location.href='change_my_language.php'" rather than an href="change_my_language.php". Am I right? Or do the major search engines scan for and follow this sort of thing nowadays?

• a completely decoupled OO system ?

  - by shrini1000

  To make an OO system as decoupled as possible, I'm thinking of the following approach: 1) we run an RMI/directory like service where objects can register and discover each other. They talk to this service through an interface 2) we run a messaging service to which objects can publish messages, and register subscription callbacks. Again, this happens through interfaces 3) when object A wants to invoke a method on object B, it discovers the target object's unique identity through #1 above, and publishes a message on the message service for object B 4) message services invokes B's callback to give it the message 5) B processes the request and sends the response for A on message service 6) A's callback is called and it gets the response. I feel this system is as decoupled as practically possible, but it has the following problems: 1) communication is typically asynchronous 2) hence it's non real time 3) the system as a whole is less efficient. Are there any other practical problems where this design obviously won't be applicable ? What are your thoughts on this design in general ?

• Recommendations with hierarchical data on non-relational databases?

  - by Luki

  I'm developing an web application that uses a non-relational database as a backend (django-nonrel + AppEngine). I need to store some hierarchical data (projects/subproject_1/subproject_N/tasks), and I'm wondering which pattern should I use. For now I thought of: Adjacency List (store the item's parent id) Nested sets (store left and right values for the item) In my case, the depth of nesting for a normal user will not exceed 4-5 levels. Also, on the UI, I would like to have a pagination for the items on the first level, to avoid to load too many items at the first page load. From what I understand so far, nested sets are great when the hierarchy is used more for displaying. Adjacency lists are great when editing on the tree is done often. In my case I guess I need the displaying more than the editing (when using nested sets, even if the display would work great, the above pagination could complicate things on editing). Do you have any thoughts and advice, based on your experience with the non-relational databases?

• Background thread in C#

  - by Xodarap

  When the user saves some data, I want to spin off a background thread to update my indexes and do some other random stuff. Even if there is an error in this indexing the user can't do anything about it, so there is no point in forcing the main thread to wait until the background thread finishes. I'm doing this from a ASP.NET process, so I think I should be able to do this (as the main thread exiting won't kill the process). When I set a breakpoint in the background thread's method though, the main thread also appears to stop. Is this just an artifact of visual studio's debugger, or is the main thread really not going to return until the background thread stops?

• System("pause"); - Why is it wrong?

  - by Faken

  Here's a question that I don't quite understand: The command, System("pause"); is taught to new programmers as a way to pause a program and wait for a keyboard input to continue. However, it seems to be frowned on by many veteran programmers as something that should not be done in varying degrees. Some people say it is fine to use. Some say it is only to be used when you are locked in your room and no one is watching. Some say that they will personally come to your house and kill you if you use it. I, myself am a new programmer with no formal programming training. I use it because I was taught to use it. What I don't understand is that if it is not something to be used, then why was I taught to use it? Or, on the flip side, is it really not that bad after all? What are your thoughts on this subject?

• PC reboots spontaenously: debugging tips [closed]

  - by aaron

  I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!

• Up to date Ruby On Rails books?

  - by Earlz

  Hello, I've been trying to learn Rails for a while now and I just can not piece it all together with random blogs and SO questions, so I've decided I need a full book/ebook. Can anyone suggest a good one? I've been looking at Agile Web Development With Rails 4th edition. There is an old question about Ruby On Rails books but it is from 2008 and there has been new Rails releases since then. I basically would like a book that is more than a reference, but also doesn't assume I'm a non-programmer. Also, I already know a lot of Ruby. So, what books would you recommend that is up to date and also doesn't treat me like a baby?

• Ruby w/ Postgres & Sinatra - Query won't order right with parameter??

  - by alleywayjack

  So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants. In my main ruby file: grants_main_order = "id_num" get '/grants' do erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]} end In the erb template: db = locals[:db] getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]]) This produces some very random ordering, however if I replace the $1 with id_num, it works as it should. Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.

• java detect clicked buttons

  - by user253530

  I have multiple panels on a JFrame window. I am going to populate each panel differently every time. For example: i start the GUI: (image center panel, right panel, bottom panel). Center panel is populated with 20 buttons, right panel with 10 buttons and bottom panel with 3. second start of the GUI (same gui). Center panel has 50 buttons, right panel has 12 buttons, bottom has 3. So everytime there is a random number of buttons, impossible to be all uniquely named. Given the fact that I don't have a unique name for each button (just a list) I would like to know which buttons were clicked according to the panel they belong to. is that possible?

• How to buffer stdout in memory and write it from a dedicated thread

  - by NickB

  I have a C application with many worker threads. It is essential that these do not block so where the worker threads need to write to a file on disk, I have them write to a circular buffer in memory, and then have a dedicated thread for writing that buffer to disk. The worker threads do not block any more. The dedicated thread can safely block while writing to disk without affecting the worker threads (it does not hold a lock while writing to disk). My memory buffer is tuned to be sufficiently large that the writer thread can keep up. This all works great. My question is, how do I implement something similar for stdout? I could macro printf() to write into a memory buffer, but I don't have control over all the code that might write to stdout (some of it is in third-party libraries). Thoughts? NickB

• jQuery doesn't fire some events while I'm not logged in (Joomla)

  - by Andrew Sekaev

  So basically, .resize function fails until I log in. What does that mean? And how that can be fixed? Almost all other functions work fine. The site is still in developement, so no live version sadly. UPDATE: jQuery(window).resize(function() { var windowSize = jQuery(window).width() var windowWidth = (jQuery(window).width()-60)/6; var windowHeight = windowWidth/1.6; /*grid resize*/ jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight}); }); This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...

• Check if CSS Class exists in StyleSheet using javascript/jQuery

  - by Akhil Sekharan

  Is there a way to check if there is a class named 'some-class-name' in css? For example, I have: <style type="text/css"> .box { position: absolute; left: 150%; } </style> My intention is to randomly assign a class to a div on certain event: var classList = []; //Need to populate this array $('#updateClass').on('click', function() { $('#resultDiv').attr('class',classList[Math.floor((Math.random()*classList.length)+1)]); }); Is it possible to check by JS/jQuery whether a class named 'box' exists in the stylesheet? Thanks.

• create a dataset by using modulo division method

  - by ayoom

  create a dataset with 101 integers. Use the modulo division method of hashing to store the random data values into hash tables with table sizes of 7, 51, and 151. Use the linear probing and quadratic method of collision resolution. Print out the tables after the data values have been stored. Search for 10 different values in each of the three hash tables, counting the number of comparisons necessary. Print out the number of comparisons necessary in each case, in tabular form.

• Stack Overflow Accessing Large Vector

  - by cam

  I'm getting a stack overflow on the first iteration of this for loop for (int q = 0; q < SIZEN; q++) { cout<<nList[q]<<" "; } nList is a vector of type int with 376 items. The size of nList depends on a constant defined in the program. The program works for every value up to 376, then after 376 it stops working. Any thoughts?

• MacOSX: OSAtomic vs OSAtomicBarrier

  - by anon

  For the functions here: #include <libkern/OSAtomic.h> there are OSAtomic and OSAtomicBarrier versions. However, the documentation does not show sample code for: When is it safe to use just OSAtomic, without the OSAtomicBarrier version When is it that OSAtomic would be unsafe, but OSAtomiBarrier would be safe. Can anyone provide explainations + sample codes? [Random ramblings of "your opinion" without actual code is useless. Readers: please down vote such answers; and vigrously upvote answers with actual code.] [C/C++ code preferred; Assembly okay too.]

• No download dialog with FileResult

  - by majkinetor

  I am returning File result from action triggered by the form post event. I can't get download dialog. Instead, if I use: return File(Encoding.UTF8.GetBytes(reportPath), "text/plain", "Report.csv"); I get path to the file upon ajax execution in the target div. When I use return File(reportPath, "text/plain", "Report.csv"); I get content of the file in the target div. Any thoughts ? The action is declared as [HttpPost] public virtual ActionResult ExportFilter(Model model) { string outputFile = CreateReport(model); return File(....) }

• Printing saved HTML to jsp keeps getting corrupted

  - by JWL

  I have a JAVA object where I save a HTML string value I call message. The saved data looks like the below, You have received a new <a href='' onclick='return popupRentalView('5282053859835904');'>Rental Request 5282053859835904</a>. Please view your open orders. But when printed to the JSP file and displayed at runtime using <%=pm.getMessage()%> or <%out.print(pm.getMessage());%> The actual html code comes out all messed up, You have received a new <a 5282053859835904');'="" onclick="return popupRentalView(" href="">Rental Request 5282053859835904</a> . Please view your open orders. Any thoughts on why the displayed string does not match the saved string? JAVA code for saving is note.setMessage("You have received a new <a href=\"\" onclick='return popupRentalView('" + requestId + "');'> Rental Request " + requestId + "</a>. Please view your open orders.");

• Getting text from a URL in ASP.NET

  - by user102533

  I am looking for a reliable way of extracting text given the web address, in ASP.NET/C#. Can anyone point me the right direction? Also, the web address could be say a news site that might have a lot of ads and menus etc. I need some intelligent way of extracting only the relevant content. Not sure how this could be done as how would I define what relevance is? Should I maybe read from a RSS feed? Any thoughts on this?

• WindowsPhone App data connection FAILS in MarketPlace published App but WORKS in Visual Studio development (same XAP)

  - by Tom

  Tearing my hair out(!) My last App update has been accepted and released by MarketPlace but the remote server data connection does NOT work/connect from the downloaded App (from MarketPlace). However, the same App (the accepted XAP) when I'm running it from Visual Studio, using the same remote server address works just fine. WHY!... Has anyone else ever run into anything like this? Here's the remote path: http://www.streamcommunication.com/ZenAwaken/DownloadableCollections.xml I can load that to a browser and retrieve the XML When I'm in Visual Studio I can connect via that path and retrieve the file and consume the data BUT!! The exact same XAP which has been accepted and distributed by Windows Phone marketplace FAILS. Is it possible that MarketPlace does something (encryption?) to the XAP that would corrupt the path string? Any thoughts or experiences would be very helpful! Tom

• Setting up Matcher for String phrase match in file

  - by randomCoder

  Having trouble figuring out how to match a phrase string to a phrase in file stream. The file I'm dealing with contains random words such as: 3 little pigs built houses and 1 little pig went to the market etc. for many lines Using "little pig" as my pattern and matcher.find() I can locate 2 matches: "little pig" and "little pigs". However, I only want it to match "little pig". What can I do? I thought about using matcher.lookingAt() but I wouldn't know how to set a proper region when I can't rely on the file string phrases I'm matching being on separate lines.

• PHP Framework Benefits / Downfalls

  - by Lizard

  I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can deffinately seen the benefits of MVC keeping the logic sperate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

• Child service not writing to event log

  - by Tommy Fisk

  I am having a very simple (but incredibly frustrating) issue with a parent service and the child service. Let's call the parent service "Service A" and the child "Service B". Both services reside on the same box. Using WCF Storm, when I send Service B a message, I see lots of entries in the event viewer for it. However, if I send a message to Service A, which calls Service B, I only see entries from Service A. So for some reason, the child logs are not written when the parent calls it, but if I call it myself, the logs do indeed show up, so I know it's not a problem with the logging or anything like that. Here is what I am using to write to the event log. // in some random static class private static EventLog el = new EventLog(); el.WriteEntry("In " + location + ", " + message); // params passed in Does anyone know why this is happening? And more importantly what I can do about it?

• Using static strings to define input field names in JSPs - good idea or not?

  - by Derek Clarkson

  Hi all, I've just be asked to work on a large portal project and have been looking through the established code. I keep finding this in the jsps: <input class="portlet-form-button" name="<%=ModifyUserProfile.FORM_FIRST_TIME_LOGIN_SUBMIT%>" type="submit" ... The authors are using static strings defined in classes to define the names of input fields and buttons in jsp forms. I've never seen this done before and was wondering if this is common practice. I'm inclined to think not, but I'm asking because, apart from centralising names which I would have thought are not likely to change, I can't see the reason why. Any thoughts on this?

• Setting a Global Doctype

  - by Batfan

  Is it possible using PHP (I was thinking may the phpinfo file or a php.ini file) or an .htaccess file to set a doctype for an entire subdirectory? Basically, in a nutshell, I'm using a software that uses XSL templates to output data to a set of HTML files. Modifying the xsl:output tag to include the doctype breaks the template and therefore, does not work. Just adding the doctype in the XSL file, breaks it as well. I need the proper doctypes in place for my CSS to function properly, cross-browser. I realize that I could add the doctype to the HTML files after export but, I'm really striving to automate this process. Any thoughts?
