  • Disable link with the prototype observe method...

    - by enyo
    I want to create a link like this: <a href="http://example.com">text</a> and replace the behavior so that the link downloads the content with Ajax instead when clicking. It is important for me not to replace the href attribute (so copying the link still works). One solution would be to do: $('link').onclick = function() { return false; }; but I would like to use the .observe method. But this doesn't work: $('link').observe('click', function() { return false; }); (which is quite logical). Any ideas on how I could achieve this? Thanks.

  • MySQL break out group clause from subquery

    - by Anton Gildebrand
    Here is my query SELECT COALESCE(js.name,'Lead saknas'), count(j.id) FROM jobs j LEFT JOIN job_sources js ON j.job_source=js.id LEFT JOIN (SELECT * FROM quotes GROUP BY job_id) q ON j.id=q.job_id GROUP BY j.job_source The problem is that it's allowed for each job to have more than one quote. Because of that i group the quotes by job_id. Now sure, this works. But i don't like the solution with a subquery. How can i break out the group clause from the subquery to the main query? I have tried to add q.job_id to the main group clause, both before and after the existing one but don't get the same results.

  • Are there Adaptive Replacement Cache patent-free alternatives?

    - by aleccolocco
    An open source high-performance project I'm working on needs to keep a cache of parsed/compiled files. A plain LRU or a plain LFU wouldn't fit. Plain LRU wouldn't work as there will be remote batch/spider processes hitting the service regularly. Plain LFU wouldn't work because content will age. ARC seems like the perfect solution but since IBM holds patents to it at least one open source project dropped it. Are there any (good enough) alternatives? EDIT: I'm not looking for exactly the same thing, just something that could handle those two situations. Perhaps some simple strategy with timestamps and sources. There have to be many programmers who faced this situation before. That's why the "good enough" bit.

  • java: speed up reading foreign characters

    - by Yang
    My current code needs to read foreign characters from the web, currently my solution works but it is very slow, since it read char by char using InputStreamReader. Is there anyway to speed it up and also get the job done? // Pull content stream from response HttpEntity entity = response.getEntity(); InputStream inputStream = entity.getContent(); StringBuilder contents = new StringBuilder(); int ch; InputStreamReader isr = new InputStreamReader(inputStream, "gb2312"); // FileInputStream file = new InputStream(is); while( (ch = isr.read()) != -1) contents.append((char)ch); String encode = isr.getEncoding(); return contents.toString();

  • Float over two elements

    - by eWolf
    My problem is rather complex to explain, so I'll show you an example: http://ewolf.bplaced.de/misc/float.htm I want to have a floated element (the blue box) to be be placed over two other elements (red and green) and I want the whole thing to be fixed-width and centered (done by the box with the black border) while the background of the red and green box should fill the whole width. I'm actually not quite sure if the way I've done it now is XHTML/CSS valid, but it works - at least in Firefox. In IE6, the green box expands to fit the whole blue box - how can I fix this in IE6 or find another solution to show it correctly in all browsers?

  • How do I alternate table row colors in asp.net mvc using jquery?

    - by grenade
    Probably a dumb question but I'm new to MVC and jQuery. I want to alternate the row colors of my tables and I've decided that I'm going to use jQuery to do it. I know that I could write an extension method (http://haacked.com/archive/2008/08/07/aspnetmvc_cycle.aspx), etc but after reading SH's comment on the article at http://haacked.com/archive/2008/05/03/code-based-repeater-for-asp.net-mvc.aspx I've picked jQuery as the solution I want to implement. I want to implement the method described at http://www.packtpub.com/article/jquery-table-manipulation-part2 but I haven't figured out where to put the initial jQuery call (eg: $(document).ready(function() {...}); Like I said, I'm new to jQuery...

  • buffer overflow with boost::program_options

    - by f4
    Hello, I have a problem using boost:program_options this simple program, copy-pasted from boosts' documentation : #include <boost/program_options.hpp> int main( int argc, char** argv ) { namespace po = boost::program_options; po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ; return 0; } fails with a buffer overflow. I have activated the "buffer security switch", and when I run it I get an "unknown exception (0xc0000409)" when I step over the line desc.add_options()... I use Visual Studio 2005 and boost 1.43.0. By the way it does run if I deactivate the switch but I don't feel comfortable doing so... unless it's possible to deactivate it locally. So do you have a solution to this problem? EDIT I found the problem I was linking against libboost_program_options-vc80-mt.lib which wasn't the good library.

  • How to handle all unhandled exceptions when using Task Parallel Library?

    - by Buu Nguyen
    I'm using the TPL (Task Parallel Library) in .NET 4.0. I want to be able to centralize the handling logic of all unhandled exceptions by using the Thread.GetDomain().UnhandledException event. However, in my application, the event is never fired for threads started with TPL code, e.g. Task.Factory.StartNew(...). The event is indeed fired if I use something like new Thread(threadStart).Start(). This MSDN article suggests to use Task#Wait() to catch the AggregateException when working with TPL, but that is not I want because it is not "centralized" enough a mechanism. Does anyone experience same problem at all or is it just me? Do you have any solution for this?

  • Apache 2.2 / Win7 - slow or not responsive

    - by joey
    My configuration - Windows 7 x64, Php 5.3, Apache 2.2.15, latest Mysql. When loading pages from localhost, the response time shown by firebug is more 530ms for the main 'index.php' file, sometimes the connection is reset. It's painfully slow. I googled the problem and found a workaround - switch off and on again a win service called BFE - base filtering engine. Then everything works like a lightning but xdebug doesn't work in netbeans. Why is this response time so long? Can you think of any other solution than BFE toggling? joey33

  • multi-dimensional ArrayList

    - by wishi
    Hi! Just a very small question... I seem to run into too much complexity here: I have to realize an index-structure like {42, someString}. I tried: Object entry[][] = new Object[1][1]; ArrayList<Object> my_list = new ArrayList<Object>(); However that looks really strange. Isn't there a better much simpler solution to just store some Integer and a String? I need to perfrom search for the Strings and return the Integer... so I thought Collections and ArrayLists are good friends in the Java API.

  • For simple C cmd programs: how to add "program executed in 12,345 seconds" ?

    - by WoodsieLord
    I'm a windows user, and I'm learning C. I use Codeblocks and visual c++ 2008 express at home to write simple C command line programs (I'm a beginner) and I find really useful when codeblocks adds a few lines at the end with the time it takes (example: "Process returned 0 (0x0) execution time : 6.848 s"). I want to add this functionality to the .exe so I can 'benchmark' or 'test' the program on a few computers. I tried using time(NULL) but it only works with 1 second precision. I also found very interesting answers here (I'm actually looking for the same thing): http://stackoverflow.com/questions/2173323/calculating-time-by-the-c-code The solution proposed by Mark Wilkins, works fine on visual c++ 2008 express on my windows 64 bit PC, but the .exe does not work anywhere else. Am I doing something wrong? I would like a method to count elapsed wall time for my programs, that must have 32bit compatibility. Thanks in advance!

  • Storing CLLocationCoordinates2D in NSMutableArray

    - by Amarsh
    After some searching, I got the following solution : ref: http://stackoverflow.com/questions/1392909/nsmutablearray-addobject-with-mallocd-struct CLLocationCoordinate2D* new_coordinate = malloc(sizeof(CLLocationCoordinate2D)); new_coordinate->latitude = latitude; new_coordinate->longitude = longitude; [points addObject:[NSData dataWithBytes:(void *)new_coordinate length:sizeof(CLLocationCoordinate2D)]]; free(new_coordinate); And access it as: CLLocationCoordinate2D* c = (CLLocationCoordinate2D*) [[points objectAtIndex:0] bytes]; However, someone claims that there is a memory leak here? Can anyone suggest me where is the leak and how to fix it. Further, is there a better way of storing a list of CLLocationCoordinate2D in NSMutableArray? Please give sample code since I am an Objective C newbie.

  • .NET security: how to check if a method is allowed to execute under current user's perrmissions

    - by Gart
    Given an ASP.NET MVC Controller class declaration: public class ItemController : Controller { public ActionResult Index() { // ... } public ActionResult Details() { // ... } [Authorize(Roles="Admin, Editor")] public ActionResult Edit() { // ... } [Authorized(Roles="Admin")] public ActionResult Delete() { // .. } } I need to reflect a list of methods in this class which may be invoked with the current user's permissions. The [Authorized] attribute is specific to ASP.NET MVC, and this is only an example. I would prefer a universal solution for this problem which works for any .NET class. Please share some ideas of what could be done in this case.

  • Renaming files: Visual Studio vs Version control

    - by Benjol
    The problem with renaming files is that if you want to take advantage of Visual Studio refactoring, you really need to do it from inside Visual Studio. But most (not all*) version control system also want to be the ones doing the renaming. One solution is to use integrated source control, but this is not always available, and in some cases is pretty clunky. I'd personally be more comfortable using source control separately, outside of Visual Studio, but I'm not sure how to manage this question of file renames. So, for those of you that use Visual Studio, which source control do you use? Do you use a VS integration (which one?) and otherwise, how do you resolve this renaming problem? (* git is smart enough to work it out for itself)

  • Android : How to Remove all capital letters from image filenames before importing into Eclipse

    - by Hubert
    As you know, you can't have capital letters in your image filenames that you use in your Android project (Ressource/Drawables folder). I've got hundreds of small images (GOOG.GIF as an exemple) that I need to import into my project (I usually do a simple drag and drop from a desktop folder into Eclipse). So here's the question : How do I quickly change all the filenames (replace all capital letters to lower case) before importing into my project ? So, GOOG.GIF becomes goog.gif AAPL.GIF becomes aapl.gif etc. Any quick command line solution or another tool to do just that ? Thanks.

  • Advanced example-driven C book with a lot of code.

    - by Inso Reiges
    Hello, I am looking for a book on advanced C programming that: Teaches how to effectively express one's solution in C when one already knows the language in depth. Shows some common design idioms expressed in C, like encapsulation, modularity and that kind of thing. Is example-driven with a lot of good-quality code. I already know the language itself so books like otherwise wonderful "Expert C Programming" by Peter van der Linden is not really what i am looking for. What i need is a book on how to express my design in C, what are the common idioms, best practices, etc. I would also like to note that i am primarily interested in C, not C++, C#, Objective-C or any other languages inspired by C-like syntax. Thank you.

  • LINQ to Entity, joining on NOT IN tables

    - by SlackerCoder
    My brain seems to be mush right now! I am using LINQ to Entity, and I need to get some data from one table that does NOT exist in another table. For example: I need the groupID, groupname and groupnumber from TABLE A where they do not exist in TABLE B. The groupID will exist in TABLE B, along with other relevant information. The tables do not have any relationship. In SQL it would be quite simply (there is a more elegant and efficient solution, but I want to paint a picture of what I need) SELECT GroupID, GroupName, GroupNumber, FROM TableA WHERE GroupID NOT IN (SELECT GroupID FROM TableB) Is there an easy/elegant way to do this? Right now I have a bunch of queries hitting the db, then comparing, etc. It's pretty messy. Thanks.

  • main content wrapper div get's pushed down the page in IE

    - by Blankman
    I have a 2 column layout, with the left side for navigation and the right side for the main content. The right side content has a wrapper div that looks like: Now this looks fine in FF and GC, and it IE but if I change the padding to anything over 4px that section gets pushed down below the left navigation. #content { padding:3px; // 4 makes it get pushed down } Does this mean IE has a different way of calculating the width of all my elements? Is this a common problem that has a solution for it?

  • Limit scope of #define

    What is the correct strategy to limit the scope of #define and avoid unwarrented token collisions. In the following configuration: Main.c # include "Utility_1.h" # include "Utility_2.h" VOID Utility() // Was written without knowing of: Utility_1 & Utility_2 { const UINT ZERO = 0; } VOID Main() { ... } // Collision; for Line:5 Compiler does not indicate what replaced Utility_1.h # define ZERO "Zero" # define ONE "One" BOOL Utility_1(); Utility_2.h # define ZERO '0' # define ONE '1' BOOL Utility_2(); Utility_2.c # include "Utility_2.h" BOOL Utility_2() { // Using: ZERO & ONE } //Collision: Character Literal replaced with String {Edit} Note: This is supposed to be a generic quesition so do not limit yourself to enum or other defined types. i.e. What to do when: I MUST USE #define Please comment on my proposed solution below.. _

  • Time Complexities of recursive algorithms

    - by Peter
    Whenever I see a recursive solution, or I write recursive code for a problem, it is really difficult for me to figure out the time complexity, in most of the cases I just say its exponential? How is it exponential actually? How people say it is 2^n, when it is n!, when it is n^n or n^k. I have some questions in mind, let say find all permutations of a string (O(n!)) find all sequences which sum up to k in an array (exponential, how exactly do I calculate). Find all subsets of size k whose sum is 0 (will k come somewhere in complexity , it should come right?). Can any1 help me how to calculate the exact complexity of such questions, I am able to wrote code for them , but its hard understanding the exact time complexity.

  • Hibernate bug using Oracle?

    - by Lothar
    Hello, I've got the problem, that I use a property in the persistence.xml which forces Hibernate to look only for tables in the given schema. <property name="hibernate.default_schema" value="FOO"/> Because we are using now 4 different schemas the actual solution is to generate 4 war files with a modified persistence.xml. That not very elegant. Does anybody know, how I can configure the schema with a property or by manipulation the JDBC connection string? I'm using Oracle 10g, 10_2_3 Patch. Thanks a lot.

  • Anyone who actually got Tycho to work?

    - by Erik Nordinder
    I'm trying to get Tycho working with m2eclipse. Problem is that all I find are outdated sites and old versions to download. I've found my way to hxxp://github.com/sonatype/sonatype-tycho and downloaded the source. Problem is that the guide at https://docs.sonatype.org/display/TYCHO/BuildingTycho isn't of much help. When trying to build I run into an error message saying I'm using invalid syntax..... And there seems to be nowhere to ask for further guidance. So are there anyone out there who actually got this working? Or got a better alternative for continuous integration / automatic build solution for eclipse plug-ins?

  • How to determine Windows Java installation location

    - by Lance May
    I'm trying to dynamically run a .jar from a C# assembly (using Process.Start(info)). Now, from a console application I am able to just run: ProcessStartInfo info = new ProcessStartInfo("java", "-jar somerandom.jar"); In an assembly, however, I keep getting a Win32Exception of "The system cannot find the file specified" and have to change the line to the full path of Java like so: ProcessStartInfo info = new ProcessStartInfo("C:\\Program Files\\Java\\jre6\\bin\\java.exe", "-jar somerandom.jar"); This obviously won't do. I need a way to dynamically (but declaratively) determine the installed location of Java. I started thinking of looking to the registry, but when I go there I noticed that there were specific keys for the versions and that they could not even be guaranteed to be numeric (e.g. "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.6" and "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.6.0_20"). What would be the most reliable "long-haul" solution to finding the most up-to-date java.exe path from a C# application? Thanks much in advance.
