  • Is there a better way to write this URL Manipulation in Python?

    - by dnolen
    I'm curious if there's a simpler way to remove a particular parameter from a url. What I came up with is the following. This seems a bit verbose. Libraries to use or a more pythonic version appreciated. parsed = urlparse(url) if parsed.query != "": params = dict([s.split("=") for s in parsed.query.split("&")]) if params.get("page"): del params["page"] url = urlunparse((parsed.scheme, None, parsed.path, None, urlencode(params.items()), parsed.fragment,)) parsed = urlparse(url)

  • how to scan a LAN for live hosts using PHP and SNMP?

    - by aag
    I would like to have a quick script listing all active hosts in a LAN, and I am a bit lost. From other posts I figured that this can be done most effectively by polling the DHCP server (in my case a Lancom router) using SNMP. However, I am not familiar with the SNMP commands in PHP. Is snmpwalk() the correct function? Can I get snmpwalk() or any other php function to return an array that contains a list of all live hosts?

  • Determining the word width in C

    - by das_weezul
    Hi! I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU. Thanks in advance, C gurus ;o)

  • Why would I use Scala/Lift over Java/Spring?

    - by Chris J
    Hi, I know this question is a bit open but I have been looking at Scala/Lift as an alternative to Java/Spring and I am wonder what are the real advantages that Scala/Lift has over it. From my perspective and experience, Java Annotations and Spring really minimizes the amount of coding that you have to do for an application. Does Scala/Lift improve upon that?

  • unobtrusive "default" text in input WITHOUT jQuery

    - by Adam Kiss
    Hello, i'm trying to write unobtrusive default/placeholder text in input (actually, relatively placed label over input, which hides on onFocus, and stays hidden if input isn't empty on onBlur), but I don't want to use jQuery, because this is the only javascript used on page - therefore using jQuery seems a bit over the top. Please, how can I do this without jQuery? Thank you.

  • Passing data to overridden base method in C#

    - by UpTheCreek
    Bit of a dumb question, but I'm wondering what the accepted way of passing data from back to an overridden base method is in c#. e.g. I guess I could do: class A { int x; public virtual void DoStuff() { Console.WriteLine(x); } } class B : A { public override void DoStuff() { x = 1; base.DoStuff(); } } But is there a better method that for example doesn't require the use of a member variable?

  • Why should Java ThreadLocal variables be static

    - by kellyfj
    I was reading that JavaDoc for Threadlocal here http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ThreadLocal.html and it says "ThreadLocal instances are typically private static fields in classes that wish to associate state with a thread (e.g., a user ID or Transaction ID). " But my question is why did they choose to make it static (typically) - it makes it a bit confusing to have "per thread" state but its static?

  • kill a process in bash

    - by wyatt
    How do I kill a process which is running in bash - for example, suppose I open a file: $ gedit file.txt is there any way within the command prompt to close it? This example is fairly trivial, since I could just close the window, but it seems to come up a bit, particularly when I mistype commands. Also is there any way to escape an executable which is running? This probably has the same solution, but I thought I'd ask anyway. Thanks

  • find all text before using regex

    - by jeff
    How can I use regex to find all text before the text "All text before this line will be included"? I have includes some sample text below for example This can include deleting, updating, or adding records to your database, which would then be reflex. All text before this line will be included You can make this a bit more sophisticated by encrypting the random number and then verifying that it is still a number when it is decrypted. Alternatively, you can pass a value and a key instead.

  • How to free static member variable in C++?

    - by user299831
    Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

  • Adding images to a JAR file in Eclipse?

    - by ChrisFreeley
    I'm trying to make a game in java, but I'm a bit of a newb. The game has images, and when I run the application from eclipse, they all show up fine. But when I export the project as an application, the images don't show up. When I put the application in the same folder as the images, they show up when I run the application, so someone suggested that I just need to put the image files inside my JAR. Can someone tell me how? Thank you
