  • DOM class injection in PHP

    - by Adam Kiss
    idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?

  • Custom constructors for models in Google App Engine (python)

    - by Nikhil Chelliah
    I'm getting back to programming for Google App Engine and I've found, in old, unused code, instances in which I wrote constructors for models. It seems like a good idea, but there's no mention of it online and I can't test to see if it works. Here's a contrived example, with no error-checking, etc.: class Dog(db.Model): name = db.StringProperty(required=True) breeds = db.StringListProperty() age = db.IntegerProperty(default=0) def __init__(self, name, breed_list, **kwargs): db.Model.__init__(**kwargs) self.name = name self.breeds = breed_list.split() rufus = Dog('Rufus', 'spaniel terrier labrador') rufus.put() The **kwargs are passed on to the Model constructor in case the model is constructed with a specified parent or key_name, or in case other properties (like age) are specified. This constructor differs from the default in that it requires that a name and breed_list be specified (although it can't ensure that they're strings), and it parses breed_list in a way that the default constructor could not. Is this a legitimate form of instantiation, or should I just use functions or static/class methods? And if it works, why aren't custom constructors used more often?

  • NoSQL replacement for memcache

    - by Juan Antonio Gomez Moriano
    We are having a situation in which the values we store on memcache are bigger than 1MB. It is not possible to make such values smaller, and even if there was a way, we need to persist them to disk. One solution would be to recompile the memcache server to allow say 2MB values, but this is either not clean nor a complete solution (again, we need to persist the values). Good news is that We can predict quite acurately how many key/values pair we are going to have We can also predict the total size we will need. A key feature for us is the speed of memcache. So question is: is there any noSQL replacement for memcache which will allow us to have values longer than 1MB AND store them in disk without loss of speed? In the past I have used tokyotyrant/cabinet but seems to be deprecated now. Any idea?

  • ASP.NET Long Process and Sending updates to Browser

    - by user204588
    Hello, I've asked this before but I was hoping for another answer and perhaps some code samples because I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this. Some code samples would be very helpful, thanks.

  • No-argument method on window.external is invoked when checking with typeof

    - by janko
    Hi, I am trying to display an HTML page with embedded JavaScript code inside a System.Windows.Forms.WebBrowser control. The JavaScript code is expected to interact with the embedding environment through the window.external object. Before invoking a method on window.external, JavaScript is supposed to check for the existance of the method. If it is not there, the code should invoke a generic fallback method. // basic idea if (typeof(window.external.MyMethod) != 'undefined') { window.external.MyMethod(args); } else { window.external.Generic("MyMethod", args); } However, checking for a no-argument method with typeof seems to invoke the method already. That is, if MyMethod accepts any positive number of arguments, the code above will work perfectly; but, if MyMethod is a no-argument method, then the expression typeof(window.external.MyMethod) will not check for its type but invoke it, too. Is there any work-around to this behavior? Can I somehow escape the expression window.external.MyMethod to prevent the method call from occurring?

  • jquery live() method on custom functions

    - by user271619
    I have a custom event handler, or I suppose some call it a custom jquery function. My problem is I'm trying to apply the live() method to it. But I'm not too successful. Here's a simple custom jquery function: $.fn.myFunction = function() { return $(this).addClass('changed'); } And here I use it: $('.changePlease').myFunction(); Ok, simple enough. But how do I apply the live() method to it?? I actually have no idea if that's even possible. But I do use live() for other things, like: $(".changePlease").live("click",function(){ alert("hello"); }); Any thoughts on this?

  • .classpath and .project - check into version control or not?

    - by amarillion
    I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

  • Obtain patterns in one file from another using ack or awk or better way than grep?

    - by Rock
    Is there a way to obtain patterns in one file (a list of patterns) from another file using ack as the -f option in grep? I see there is an -f option in ack but it's different with the -f in grep. Perhaps an example will give you a better idea. Suppose I have file1: file1: a c e And file2: file2: a 1 b 2 c 3 d 4 e 5 And I want to obtain all the patterns in file1 from file2 to give: a 1 c 3 e 5 Can ack do this? Otherwise, is there a better way to handle the job (such like awk or using hash) because I have millions of records in both files and really need an efficient way to complete? Thanks!

  • What is the need for normalizing a vector?

    - by Rashed Hassan
    Trying to understand vectors a bit more. What is the need for normalizing a vector? If I have a vector, N = (x, y, z) What do you actually get when you normalize it - I get the idea you have to divide x/|N| y/|N| & z/|N|. My question is, why do we do this thing, I mean what do we get out of this equation? What is the meaning or 'inside' purpose of doing this. A bit of a maths question, I apologize, but I am really not clear in this topic.

  • Castle windsor registration

    - by nivlam
    interface IUserService class LocalUserService : IUserService class RemoteUserService : IUserService interface IUserRepository class UserRepository : IUserRepository If I have the following interfaces and classes, where the IUserService classes have a dependency on IUserRepository. I can register these components by doing something like: container.AddComponent("LocalUserService", typeof(IUserService), typeof(LocalUserService)); container.AddComponent("RemoteUserService", typeof(IUserService), typeof(RemoteUserService)); container.AddComponent("UserRepository", typeof(IUserRepository), typeof(UserRepository)); ... and get the service I want by calling: IUserService userService = container.Resolve<IUserService>("RemoteUserService"); However, if I have the following interfaces and classes: interface IUserService class UserService : IUserService interface IUserRepository class WebUserRepository : IUserRepository class LocalUserRepository : IUserRepository class DBUserRepository : IUserRepository How do I register these components so that the IUserService component can "choose" which repository to inject at runtime? My idea is to allow the user to choose which repository to query from by providing 3 radio buttons (or whatever) and ask the container to resolve a new IUserService each time.

  • How exactly does dependency injection reduce coupling?

    - by dotnetdev
    Hi, I've done plenty of reading on Dependency Injection, but I have no idea, how does it actually reduce coupling? The analogy I have of DI is that all components are registered with a container, so theyre are like in a treasure chest. To get a component, you obviously register it first, but then you would have to interrogate the treasure chest (which is like a layer of indirection). Is this the right analogy? It doesn't make obvious how the "injection" happens, though (how would that fit in with this analogy?). Thanks

  • Access the internal phonebook

    - by L0rdAli3n
    For more than two days now, I'm trying to grab a list of all contacts, from the internal phonebook (no facebook-, gmail- or twittercontacts) with their family- and givenname. I managed to get a list with all contacts, socialcontacts included. So I looked at the account_type and saw that on my HTC Desire they were all "com.htc.android.pcsc" and I was like "Great, I just have to filter the whole list". But then all people with non-htc android cellphones would be unable to use my app, if I would hardcode this filter. Next idea was to let the user choose which account he wants to use, but unfortunately the "com.htc.android.pcsc" didn't appear in the list I got from the AccountManager?!? So my question is: Is there any standardized way to access the internal phonebook? I'm really stuck with that and any hint is highly appreciated!

  • JSP cant find bean Class using "" modifiers

    - by Ravana
    Hey I'm using Netbeans for my IDE and I'm getting an error when I try to run my EJB program. I get an error when I declare and give the path of the class in my JSP to a bean. <jsp:useBean id="book" class="BookBean.Book" scope="application" /> <jsp:setProperty name="book" property="*" /> When I run the program I get this error javax.servlet.ServletException: java.lang.InstantiationException: class BookBean.Book : java.lang.IllegalAccessException: Class java.beans.Beans can not access a member of class BookBean.Book with modifiers "" and java.lang.InstantiationException: class BookBean.Book : java.lang.IllegalAccessException: Class java.beans.Beans can not access a member of class BookBean.Book with modifiers "" I removed the "" and put in '' to see if that works, but it doesn't. Any idea? I also put a breakpoint there and it def. is the root of the problem. Thanks.

  • Getting Notifications in Background Mode iOS?

    - by Pau Senabre
    I'm trying to get Notifications in Background Mode by running a method every minute to see if there are new notifications. This works great in Active Mode, but I saw for background mode it is restricted to 7 keys. I enabled the Background Mode with the option Background Fetch, but seems like the method is being called but it's not complete. In AppDelegate I'm calling: - (void)applicationDidEnterBackground:(UIApplication *)application { //This has a Timer to execute every minute [self GetNotifications]; //This executes a NSMutableURLRequest *request //giving back the JSON data with the notifications } I would like to do something like Facebook does for Notifications. Any idea how to do this?

  • fast scrolling background

    - by Andre
    i want a game that scrolls the background in a similar way to a UItableView. I solved it with a timer that moves the background up and brings another copy of the same picture up if (bg1.center.y <= - self.view.bounds.size.height/2 ) { bg1.center = CGPointMake(bg1.center.x, 690); } if (bg2.center.y <= - self.view.bounds.size.height/2 ) { bg2.center = CGPointMake(bg2.center.x, 690); bg1.center = CGPointMake(bg1.center.x, bg1.center.y - movement); bg2.center = CGPointMake(bg2.center.x, bg2.center.y - movement); But the faster i move the pictures the more problems occur: There are appearing gaps between the backgrounds and they are getting biggiger the faster i move them! movement is defined by the speed of swiping over the screen Any idea to solve that?

  • How to stop IE8 from expanding a nested div's width to fit parent div?

    - by Tony_Henrich
    I have a page with several levels of divs. In one of the inner divs, there are two divs (1 & 2) which have float; left so that they are on the same horizontal level. It looks good in FireFox, but in the IE8, div 2 is below div 1. I turned the borders on and noticed div2 (violet border) is filling the width of the parent box. In FF, the width is the width of all the content only. If I use a hard coded width (not a good idea), IE8 displays it fine. How can I make IE8 not expand the width of div2 to the right edge of its parent div? IE8 (not good: div2 width is expanded) Firefox (good: width of div2 is not expanded)

  • Can you safely rely upon Yahoo Pipes to offload ETL for your application?

    - by Daniel DiPaolo
    Yahoo Pipes are a very intriguing choice for sort of a poor-man's server-free ETL solution, but would it be a good idea to build an application around one or many Pipes? I've really only used them for toy things here and there, with the only thing I've used longer than a week or two being one amalgamated and filtered RSS feed that I've plugged into Google Reader (which has worked great, but if it goes out for a while I wouldn't notice). So, my question is, would building an application around Yahoo Pipes be reliable (available most of the time)? Ideally it'd be something I could rely on being up 99+% of the time. It looks like the Pipes Terms of Use permit building apps around it, but I am unfamiliar with anyone building anything significant using them.

  • Reflection & Parameters in C#

    - by Jim
    Hello, I'm writing an application that runs "things" to a schedule. Idea being that the database contains assembly, method information and also the parameter values. The timer will come along, reflect the method to be run, add the parameters and then execute the method. Everything is fine except for the parameters. So, lets say the method accepts an ENUM of CustomerType where CustomerType has two values of CustomerType.Master and CustomerType.Associate. EDIT I don't the type of parameter that will be getting passed in. ENUM used as an example END OF EDIT We want to run Method "X" and pass in parameter "CustomerType.Master". In the database, there will be a varchar entry of "CustomerType.Master". How do I convert the string "CustomerType.Master" into a type of CustomerType with a value of "Master" generically? Thanks in advance, Jim

  • problem in reading output of dd command using pipe

    - by Ummar
    I am developing an application, in which I want to redirect the output (progress information) of dd command to my C++ program, but it is not actually getting the output, here is the code FILE * progressInfo = popen("gzip -dc backup/backup.img.gz | pv -ptrbe -i 2 -s 2339876653 | dd of=/dev/sdb","r"); if(!progressInfo) { return -1; } char buf[1024]; while(fgets(buff, sizeof(buff),progressInfo)!=NULL) { std::cout << buff << endl; } but the problem is the progress information is not received in buff, and the output is continuously printed on terminal, and above program halts on while(fgets(buff, sizeof(buff),progressInfo)!=NULL), and as soon as the dd operation is completed, the very next line to loop block is executed. if anyone has any idea why the output is not returned to buff, and its continuously retuned on terminal?

  • Is it hard problem?

    - by Lukasz Lew
    I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach.

  • Hibernate, alter identifier/primary key

    I receive the following exception when Im trying to alter my @ID in an @Entity. identifier of an instance of com.google.search.pagerank.ItemEntity was altered from 1 to 2. I know that im altering the primary key in my table. Im using JPA-annotations. I solved this by using this single HQL query: update Table set name=:newName where name=:oldName instead of using the more oo approach: beginTransaction(); T e = session.load(...); e.setName(newName); session.saveOrUdate(e); commit(); Any idea what the diff is?

  • html vertical space between blocks appears

    Please have a look at this page www.pixeli.ca/issue. I have begun making a page layout using CSS framework 960.gs. My problem is that there is some strange space appears between block with top image and blue block with "hello" string. So you can see a green stripe there that shouldn't be visible at all. I tried different variants and have no idea what's wrong with it. I noticed that it happens only with the block with images inside them, but if there is only text, no space happens. Thanks.
