  • retrieving 'nulls' from website using Java URL input stream

    - by Roio
    hi all, i'm trying to read the text from a website using the Java URL input stream as follows - URL u = new URL(str); br3 = new BufferedReader(new InputStreamReader(u.openStream())); while(true) System.out.println(br3.readLine()); this seems to work fine for most websites, but for some url shortening services like linkbee, the object draws a blank. e.g. http://linkbee.com/FUAKF, i can view the source code using an explorer, however i repeatedly get nulls when i use the above code.

  • SED whitespace removal within a string

    - by blazeprogrammer
    I'm trying to use sed to replace whitespace within a string. For example, given the line: var test = 'Some test text here.'; I want to get: var test = 'Sometesttexthere.'; I've tried using (\x27 matches the '): sed 's|\x27\([^x27[:space:]]*\)[[:space:]]|\x27\1|g but that just gives var test = 'Sometest text here.'; Any ideas?

  • HTML Special Entity Codes in Actionscript3/Flex

    - by BlairHippo
    I have a Flex/Actionscript 3 application that displays RSS feeds in a Text element. It strips out any HTML formatting present, but it's not handling HTML special entity codes properly -- it's rendering &mdash as the literal string instead of replacing it with an em-dash, etc. Is there any systematic way I can make it handle those codes properly, or am I going to need to manually replace those strings regex style?

    - by Patrick
    Hi! I want to upgrade jQuery inside my drupal installation. At the moment I have jQuery 1.2.6 and I would like to upgrade it to jQuery 1.4 I guess some Drupal modules still depends on the old jQuery version. I've tried jquery_update module to upgrade jQuery, but it didn't work. It asked to replace the original Drupal files in the "misc" folder with the new ones, but it didn't work. Anyway, I was wondering if there is a better method instead of using another module thanks

  • TCP Scanner Python MultiThreaded

    - by user1473508
    I'm trying to build a small tcp scanner for a netmask. The code is as follow: import socket,sys,re,struct from socket import * host = sys.argv[1] def RunScanner(host): s = socket(AF_INET, SOCK_STREAM) s.connect((host,80)) s.settimeout(0.1) String = "GET / HTTP/1.0" s.send(String) data = s.recv(1024) if data: print "host: %s have port 80 open"%(host) Slash = re.search("/", str(host)) if Slash : netR,_,Wholemask = host.partition('/') Wholemask = int(Wholemask) netR = struct.unpack("!L",inet_aton(netR))[0] for host in (inet_ntoa(struct.pack("!L", netR+n)) for n in range(0, 1<<32-Wholemask)): try: print "Doing host",host RunScanner(host) except: pass else: RunScanner(host) To launch : python script.py 10.50.23.0/24 The problem I'm having is that even with a ridiculous low settimeout value set, it takes ages to cover the 255 ip addresses since most of them are not assigned to a machine. How can i make a way faster scanner that wont get stuck if the port is close.MultiThreading ? Thanks !

  • In Perl, can I limit the length of a line as I read it in from a file (like fgets)

    - by SB
    I'm trying to write a piece of code that reads a file line by line and stores each line, up to a certain amount of input data. I want to guard against the end-user being evil and putting something like a gig of data on one line in addition to guarding against sucking in an abnormally large file. Doing $str = <FILE> will still read in a whole line, and that could be very long and blow up my memory. fgets lets me do this by letting me specify a number of bytes to read during each call and essentially letting me split one long line into my max length. Is there a similar way to do this in perl? I saw something about sv_gets but am not sure how to use it (though I only did a cursory Google search). Thanks.

  • Any method to denote object assignment?

    - by Droogans
    I've been studying magic methods in Python, and have been wondering if there's a way to outline the specific action of: a = MyClass(*params).method() versus: MyClass(*params).method() In the sense that, perhaps, I may want to return a list that has been split on the '\n' character, versus dumping the raw list into the variable a that keeps the '\n' intact. Is there a way to ask Python if its next action is about to return a value to a variable, and change action, if that's the case? I was thinking: class MyClass(object): def __init__(*params): self.end = self.method(*params) def __asgn__(self): return self.method(*params).split('\n') def __str__(self): """this is the fallback if __asgn__ is not called""" return self.method(*params)

  • PHP Multiple form tokens

    - by Juddling
    I understand the idea of generating a form token and storing it in a session, and also putting it as a hidden input in my forms. But how could I make this work if I have pages with multiple forms, is it still safe to use the same token for each form? And I still feel weary about bots and stuff on my website, can these form tokens really safely replace CAPTCHAs?
