• Ubuntu 9.10 and Squid 2.7 Transparent Proxy TCP_DENIED

  - by user298814

  Hi, We've spent the last two days trying to get squid 2.7 to work with ubuntu 9.10. The computer running ubuntu has two network interfaces: eth0 and eth1 with dhcp running on eth1. Both interfaces have static ip's, eth0 is connected to the Internet and eth1 is connected to our LAN. We have followed literally dozens of different tutorials with no success. The tutorial here was the last one we did that actually got us some sort of results: http://www.basicconfig.com/linuxnetwork/setup_ubuntu_squid_proxy_server_beginner_guide. When we try to access a site like seriouswheels.com from the LAN we get the following message on the client machine: ERROR The requested URL could not be retrieved Invalid Request error was encountered while trying to process the request: GET / HTTP/1.1 Host: www.seriouswheels.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.9 (KHTML, like Gecko) Chrome/5.0.307.11 Safari/532.9 Cache-Control: max-age=0 Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,/;q=0.5 Accept-Encoding: gzip,deflate,sdch Cookie: __utmz=88947353.1269218405.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none); __qca=P0-1052556952-1269218405250; __utma=88947353.1027590811.1269218405.1269218405.1269218405.1; __qseg=Q_D Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Some possible problems are: Missing or unknown request method.

Your cache administrator is webmaster. Below are all the configuration files: /etc/squid/squid.conf, /etc/network/if-up.d/00-firewall, /etc/network/interfaces, /var/log/squid/access.log. Something somewhere is wrong but we cannot figure out where. Our end goal for all of this is the superimpose content onto every page that a client requests on the LAN. We've been told that squid is the way to do this but at this point in the game we are just trying to get squid setup correctly as our proxy.

• How to make jQuery animate upwards

  - by ivannovak

  Hey there, I've got some jquery running fairly well, howeever when I hover over the element in question, the bottom expands downward which is not unexpected but is not the desired effect. I'd like the bottom of the element to remain stationary with the top of the element expanding upwards. If you'd like to see what I currently have, you may navigate to http://demo.ivannovak.com/mobia/ Any help would be greatly appreciated. Here is my code: HTML <div class="button"> <h3>Product Quality</h3> <div>Duis tristique ultricies velit sit amet adipiscing.</div> <img src="<?php bloginfo('template_url'); ?>/assets/img/INgravatar_subernova.png" alt="placeholderImage" height="70" /> <p><a href="#">Learn More &gt;</a></p> <div class="bottom"></div> </div> CSS div#buttons {} div#buttons .button { background: url(assets/img/bg_blue_top.jpg) #206094 no-repeat top left; padding: 5px 10px 0; width: 209px; float: left; margin-right: 5px; position: relative; height: 50px; } div#buttons .button h3 { font-weight: normal; color: #fff; text-transform: uppercase; } div#buttons .button:hover div, div#buttons .button:hover img { /* display: block; */ } div#buttons .button div { width: 120px; padding-right: 20px; float: left; color: #bbb; display: none; } div#buttons .button img { float: right; display: none; } div#buttons .button p { position: absolute; bottom: 10px; left: 10px; z-index: 9; font-weight: bold; text-transform: uppercase; } div#buttons .button p a { color: #7bc143; text-decoration: none; } div#buttons .button p a:hover { text-decoration: underline; } div#buttons .button .bottom { background: url(assets/img/bg_blue_bottom.jpg) no-repeat bottom left; height:26px; position: absolute; display: block; width: 229px; right: 0px; padding:0; bottom: 0; } jQuery $(document).ready(function() { $('.button').mouseenter(function() { $(this).closest('div').animate({ height: "150px", }, 400, "swing"); }); $('.button').mouseleave(function() { $(this).closest('div').animate({ height: "50px", }, 400, "swing"); }); });

• Python - pyparsing unicode characters

  - by mgj

  Hi..:) I tried using w = Word(printables), but it isn't working. How should I give the spec for this. 'w' is meant to process Hindi characters (UTF-8) The code specifies the grammar and parses accordingly. 671.assess :: ????? ::2 x=number + "." + src + "::" + w + "::" + number + "." + number If there is only english characters it is working so the code is correct for the ascii format but the code is not working for the unicode format. I mean that the code works when we have something of the form 671.assess :: ahsaas ::2 i.e. it parses words in the english format, but I am not sure how to parse and then print characters in the unicode format. I need this for English Hindi word alignment for purpose. The python code looks like this: # -*- coding: utf-8 -*- from pyparsing import Literal, Word, Optional, nums, alphas, ZeroOrMore, printables , Group , alphas8bit , # grammar src = Word(printables) trans = Word(printables) number = Word(nums) x=number + "." + src + "::" + trans + "::" + number + "." + number #parsing for eng-dict efiledata = open('b1aop_or_not_word.txt').read() eresults = x.parseString(efiledata) edict1 = {} edict2 = {} counter=0 xx=list() for result in eresults: trans=""#translation string ew=""#english word xx=result[0] ew=xx[2] trans=xx[4] edict1 = { ew:trans } edict2.update(edict1) print len(edict2) #no of entries in the english dictionary print "edict2 has been created" print "english dictionary" , edict2 #parsing for hin-dict hfiledata = open('b1aop_or_not_word.txt').read() hresults = x.scanString(hfiledata) hdict1 = {} hdict2 = {} counter=0 for result in hresults: trans=""#translation string hw=""#hin word xx=result[0] hw=xx[2] trans=xx[4] #print trans hdict1 = { trans:hw } hdict2.update(hdict1) print len(hdict2) #no of entries in the hindi dictionary print"hdict2 has been created" print "hindi dictionary" , hdict2 ''' ####################################################################################################################### def translate(d, ow, hinlist): if ow in d.keys():#ow=old word d=dict print ow , "exists in the dictionary keys" transes = d[ow] transes = transes.split() print "possible transes for" , ow , " = ", transes for word in transes: if word in hinlist: print "trans for" , ow , " = ", word return word return None else: print ow , "absent" return None f = open('bidir','w') #lines = ["'\ #5# 10 # and better performance in business in turn benefits consumers . # 0 0 0 0 0 0 0 0 0 0 \ #5# 11 # vHyaapaar mEmn bEhtr kaam upbhOkHtaaomn kE lIe laabhpHrdd hOtaa hAI . # 0 0 0 0 0 0 0 0 0 0 0 \ #'"] data=open('bi_full_2','rb').read() lines = data.split('!@#$%') loc=0 for line in lines: eng, hin = [subline.split(' # ') for subline in line.strip('\n').split('\n')] for transdict, source, dest in [(edict2, eng, hin), (hdict2, hin, eng)]: sourcethings = source[2].split() for word in source[1].split(): tl = dest[1].split() otherword = translate(transdict, word, tl) loc = source[1].split().index(word) if otherword is not None: otherword = otherword.strip() print word, ' <-> ', otherword, 'meaning=good' if otherword in dest[1].split(): print word, ' <-> ', otherword, 'trans=good' sourcethings[loc] = str( dest[1].split().index(otherword) + 1) source[2] = ' '.join(sourcethings) eng = ' # '.join(eng) hin = ' # '.join(hin) f.write(eng+'\n'+hin+'\n\n\n') f.close() ''' if an example input sentence for the source file is: 1# 5 # modern markets : confident consumers # 0 0 0 0 0 1# 6 # AddhUnIk baajaar : AshHvsHt upbhOkHtaa . # 0 0 0 0 0 0 !@#$% the ouptut would look like this :- 1# 5 # modern markets : confident consumers # 1 2 3 4 5 1# 6 # AddhUnIk baajaar : AshHvsHt upbhOkHtaa . # 1 2 3 4 5 0 !@#$% Output Explanation:- This achieves bidirectional alignment. It means the first word of english 'modern' maps to the first word of hindi 'AddhUnIk' and vice versa. Here even characters are take as words as they also are an integral part of bidirectional mapping. Thus if you observe the hindi WORD '.' has a null alignment and it maps to nothing with respect to the English sentence as it doesn't have a full stop. The 3rd line int the output basically represents a delimiter when we are working for a number of sentences for which your trying to achieve bidirectional mapping. What modification should i make for it to work if the I have the hindi sentences in Unicode(UTF-8) format.

• Simple Observation in Django: How Can I Correctly Modify The `attrs` sent to __new__ of a Django Mod

  - by DGGenuine

  Hello, I'm a strong proponent of the observer pattern, and this is what I'd like to be able to do in my Django models.py: class AModel(Model): __metaclass__ = SomethingMagical @post_save(AnotherModel) @classmethod def observe_another_model_saved(klass, sender, instance, created, **kwargs): pass @pre_init('YetAnotherModel') @classmethod def observe_yet_another_model_initializing(klass, sender, *args, **kwargs): pass @post_delete('DifferentApp.SomeModel') @classmethod def observe_some_model_deleted(klass, sender, **kwargs): pass This would connect a signal with sender = the decorator's argument and receiver = the decorated method. Right now my signal connection code all exists in __init__.py which is okay, but a little unmaintainable. I want this code all in one place, the models.py file. Thanks to helpful feedback from the community I'm very close (I think.) (I'm using a metaclass solution instead of the class decorator solution in the previous question/answer because you can't set attributes on classmethods, which I need.) I am having a strange error I don't understand. At the end of my post are the contents of a models.py that you can pop into a fresh project/application to see the error. Set your database to sqlite and add the application to installed apps. This is the error: Validating models... Unhandled exception in thread started by Traceback (most recent call last): File "/Library/Python/2.6/site-packages//lib/python2.6/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 253, in validate raise CommandError("One or more models did not validate:\n%s" % error_text) django.core.management.base.CommandError: One or more models did not validate: local.myothermodel: 'my_model' has a relation with model MyModel, which has either not been installed or is abstract. I've indicated a few different things you can comment in/out to fix the error. First, if you don't modify the attrs sent to the metaclass's __new__, then the error does not arise. (Note even if you copy the dictionary element by element into a new dictionary, it still fails; only using the exact attrs dictionary works.) Second, if you reference the first model by class rather than by string, the error also doesn't arise regardless of what you do in __new__. I appreciate your help. I'll be githubbing the solution if and when it works. Maybe other people would enjoy a simplified way to use Django signals to observe application happenings. #models.py from django.db import models from django.db.models.base import ModelBase from django.db.models import signals import pdb class UnconnectedMethodWrapper(object): sender = None method = None signal = None def __init__(self, signal, sender, method): self.signal = signal self.sender = sender self.method = method def post_save(sender): return _make_decorator(signals.post_save, sender) def _make_decorator(signal, sender): def decorator(view): return UnconnectedMethodWrapper(signal, sender, view) return decorator class ConnectableModel(ModelBase): """ A meta class for any class that will have static or class methods that need to be connected to signals.

• What is the cause of exception in wcf peer-to-peer service with callbacks ?

  - by miensol

  I've been playing around with WCF peer to peer, one way operation contract and callbacks. I have a following service: [ServiceContract(CallbackContract = typeof(ICodeFoundCallback))] public interface ICodeSearch { [OperationContract(IsOneWay = true)] void Search(string searchQuery); } public interface ICodeFoundCallback { [OperationContract(IsOneWay = true)] void Found(string found); } public class CodeSearchService : ServiceWithCallback<ICodeFoundCallback>, ICodeSearch { public void Search(string searchQuery) { Console.WriteLine("Searching for :" + searchQuery); Callback(t=> t.Found(searchQuery)); } } public class ServiceWithCallback<T> { protected void Callback(Action<T> call) { var callbackChanel = OperationContext.Current.GetCallbackChannel<T>(); call(callbackChanel); } } with such config on server <system.serviceModel> <services> <service name="CodeSearch.Service.CodeSearchService" behaviorConfiguration="CodeSearchServiceBehavior"> <host> <baseAddresses> <add baseAddress="net.p2p://CodeSearchService"/> </baseAddresses> </host> <endpoint name="CodeSearchServiceEndpoint" address="" binding="netPeerTcpBinding" bindingConfiguration="BindingUnsecure" contract="CodeSearch.Service.ICodeSearch" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="CodeSearchServiceBehavior"> <serviceMetadata /> </behavior> </serviceBehaviors> </behaviors> <bindings> <netPeerTcpBinding> <binding name="BindingUnsecure"> <security mode="None"/> <resolver mode="Pnrp"/> </binding> </netPeerTcpBinding> <customBinding> <binding name="CodeSearchServiceEndpoint"> <binaryMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" maxSessionSize="2048"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> </binaryMessageEncoding> <peerTransport maxBufferPoolSize="524288" maxReceivedMessageSize="65536" port="0"> <security mode="None" /> </peerTransport> </binding> </customBinding> </bindings> <system.serviceModel> And simple client generated by Visual studio tooling.

Could anyone help me solve this issue ?

• Calling webservice from WCF service

  - by Balaji

  I am having an issue consuming a webservice (c#.net) from a WCF service. The error i am getting is EndPointNotFoundException "TCP error code 10061: No connection could be made because the target machine actively refused it" I wrote a unit test to check if i could send a request to the web service and it worked fine [The unit test is using the same binding configuration as my WCF service] The web service and WCF service (client) have basichttp binding. Did anyone had similar kind of issue calling a webservice from a WCF service? The service Model section is as follows <system.serviceModel> <bindings> <basicHttpBinding> <binding name="DataService" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> <message clientCredentialType="UserName" algorithmSuite="Default"/> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://10.22.33.67/Service/DataService.asmx" binding="basicHttpBinding" bindingConfiguration="DataService" contract="Service.DataService" name="DataService"/> </client> <services> <service name="TestToConsumeDataService.WCFHost.Service1" behaviorConfiguration="TestToConsumeDataService.WCFHost.Service1Behavior"> <!-- Service Endpoints --> <endpoint address="" binding="basicHttpBinding" contract="TestToConsumeDataService.WCFHost.IService1"> <!-- Upon deployment, the following identity element should be removed or replaced to reflect the identity under which the deployed service runs.

• Python - help on custom wx.Python (pyDev) class

  - by Wallter

  I have been hitting a dead end with this program. I am trying to build a class that will let me control the BIP's of a button when it is in use. so far this is what i have (see following.) It keeps running this weird error TypeError: 'module' object is not callable - I, coming from C++ and C# (for some reason the #include... is so much easier) , have no idea what that means, Google is of no help so... I know I need some real help with sintax and such - anything woudl be helpful. Note: The base code found here was used to create a skeleton for this 'custom button class' Custom Button import wx from wxPython.wx import * class Custom_Button(wx.PyControl): # The BMP's # AM I DOING THIS RIGHT? - I am trying to get empty 'global' # variables within the class Mouse_over_bmp = None #wxEmptyBitmap(1,1,1) # When the mouse is over Norm_bmp = None #wxEmptyBitmap(1,1,1) # The normal BMP Push_bmp = None #wxEmptyBitmap(1,1,1) # The down BMP Pos_bmp = wx.Point(0,0) # The posisition of the button def __init__(self, parent, NORM_BMP, PUSH_BMP, MOUSE_OVER_BMP, pos, size, text="", id=-1, **kwargs): wx.PyControl.__init__(self,parent, id, **kwargs) # The conversions, hereafter, were to solve another but.

• .animate question/help

  - by Josh

  So, I've built this navigation bar so far and I'm curious if it's even possible to achieve what I'm thinking. Currently, when you hover over each of the links they drop down (padding is increased). Now, what I'm curious in doing is if you hover over say "test1", test2-4 also drop with it but in the padding that has been created from the drop down, "test1" information shows up. Allowing the user to click or read whatever information is in there. Also, if the user would like to, they can move their mouse to test2 and everything would animate (opacity, this I can do I think) to whatever is in the test2 field, test3 doing the same and so on. I haven't had much success with this, I've created a completely separate panel before, but that didn't exactly work or I wasn't doing it correctly. Here is what I've been working on, ANY help would be appreciated!

• Internet Explorer ajax request not returning anything

  - by Ryan Giglio

  At the end of my registration process you get to a payment screen where you can enter a coupon code, and there is an AJAX call which fetches the coupon from the database and returns it to the page so it can be applied to your total before it is submitted to paypal. It works great in Firefox, Chrome, and Safari, but in Internet Explorer, nothing happens. The (data) being returned to the jQuery function appears to be null. jQuery Post function applyPromo() { var enteredCode = $("#promoCode").val(); $(".promoDiscountContainer").css("display", "block"); $(".promoDiscount").html("<img src='/images/loading.gif' alt='Loading...' title='Loading...' height='18' width='18' />"); $.post("/ajax/lookup-promo.php", { promoCode : enteredCode }, function(data){ if ( data != "error" ) { var promoType = data.getElementsByTagName('promoType').item(0).childNodes.item(0).data; var promoAmount = data.getElementsByTagName('promoAmount').item(0).childNodes.item(0).data; $(".promoDiscountContainer").css("display", "block"); $(".totalWithPromoContainer").css("display", "block"); if (promoType == "percent") { $("#promoDiscount").html("-" + promoAmount + "%"); var newPrice = (originalPrice - (originalPrice * (promoAmount / 100))); $("#totalWithPromo").html(" $" + newPrice); if ( promoAmount == 100 ) { skipPayment(); } } else { $("#promoDiscount").html("-$" + promoAmount); var newPrice = originalPrice - promoAmount; $("#totalWithPromo").html(" $" + newPrice); } $("#paypalPrice").val(newPrice + ".00"); $("#promoConfirm").css("display", "none"); $("#promoConfirm").html("Promotion Found"); finalPrice = newPrice; } else { $(".promoDiscountContainer").css("display", "none"); $(".totalWithPromoContainer").css("display", "none"); $("#promoDiscount").html(""); $("#totalWithPromo").html(""); $("#paypalPrice").val(originalPrice + ".00"); $("#promoConfirm").css("display", "block"); $("#promoConfirm").html("Promotion Not Found"); finalPrice = originalPrice; } }, "xml"); } Corresponding PHP Page include '../includes/dbConn.php'; $enteredCode = $_POST['promoCode']; $result = mysql_query( "SELECT * FROM promotion WHERE promo_code = '" . $enteredCode .

I know this is wrong way. I should set left position instead of hiding content but it is empty I tried to set left position but no luck. Let me know How the block can be moved one by one using javascript and what is the best approach to do this?

• css, unordered list not displaying icon in right place...

  - by Ronedog

  I'm really frustrated with this one. A few weeks ago I got it working in both firefox and ie just fine. Went back today to do some testing and found a problem with the display in firefox and I've been searching the code but can't find anything. I could use a few tips from anyone willing, I'm sure I'm looking at the wrong things. I upgraded my firefox version but I imagine my code is broke, not firefox. I'm assuming the problem is somewhere in my css file, but I'm not sure. Here's what I've confirmed so far. There don't seem to be conflicts in other css files with < ul 's or < li 's that may be overriding settings. The other confirmation is that This works fine in Internet Explorer...therefore I must be an idiot, because its usually been the other way around (working in FF, but failing in IE). Here's How it looks in IE (Notice the position of the folder icon right next to the text): Here's how it looks in FF (Notice the folder icon is not being pushed down with its corresponding text). Here's the Unordered List: <ul id="nav"> <li><a>Utah</a></li> <ul> <li><a>ParkCity</a> <ul> <li><a>Com1</a></li> <ul> <li class="folder_closed"><a>Timber</a></li> <div>SQUARE CONTAINER IS INSIDE THIS DIV</div> </ul> </ul> </ul> </ul> Here's the CSS that is used for the whole menu: /* MENU NAVIGATION (<UL><LI> LISTS ****************************************/ ul#nav{ /* This handles the main root <ul> */ margin-left:0; margin-right:0; padding-left:0px; text-indent:15px; } ul#nav div{ overflow: hidden; } #nav li>a:hover { cursor: pointer; } #nav li > ul{ /* This will hide any element with an id of "nav" and an "li" that has a direct child that is a "ul" */ display:none; margin-left:0px; margin-right:0px; padding-left:15px; padding-right:0px; text-indent:15px; } #nav li { list-style-type:none; list-style-image: none; } #nav > li{ vertical-align: top; left:0px; text-align:left; clear: both; margin:0px; margin-right:0px; padding-right:0px; } .menu_parent{ background-image: url(../images/maximize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .menu_parent_minimized{ background-image: url(../images/minimize.png); background-repeat: no-repeat; background-position: 0px 1px; position:relative; } .folder_closed{ position:relative; background-image: url(../images/folder_closed12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } .folder_open{ position:relative; background-image: url(../images/folder_open12x14.png); background-repeat: no-repeat; background-position: 0px -2px; } </ul>

Paticularly I want to fade in the .menu li a:hover class with jquery. .menu { padding:0; margin:0; list-style:none; } .menu li { float:left; margin-left:1px; } .menu li a { display:block; height:44px; line-height:40px; padding:0 5px; float:right; color:#fff; text-decoration:none; font-family:"Palatino Linotype", "Book Antiqua", Palatino, serif; font-size:12px; font-weight:bold; } .menu li a b { text-transform:uppercase; } .menu li a:hover { color:#E4FFC5; background: url(../images/arrow.png) no-repeat center bottom; } .current { background: url(../images/arrow.png) no-repeat center bottom; font-size:16px; font-weight:bold; } .spacer p { display:block; height:44px; line-height:40px; padding:0 5px; float:right; color:#fff; text-decoration:none; font-family:"Palatino Linotype", "Book Antiqua", Palatino, serif; font-size:12px; font-weight:bold; } <ul class="menu"> <li class="current"><a href="index.html">Home</a></li> <li class="spacer"> <p>|</p> </li> <li><a href="#">Mission &amp; Values </a></li> <li class="spacer"> <p>|</p> </li> <li><a href="#">Caregivers</a></li> <li class="spacer"> <p>|</p> </li> <li><a href="#">Special Programs </a></li> <li class="spacer"> <p>|</p> </li> <li><a href="#">Enployment</a></li> <li class="spacer"> <p>|</p> </li> <li><a href="#">Contact</a></li> </ul> <script type="text/javascript"> $(function() { $('a').mouseover(function() { $('.logo').animate ({opacity:'0.6'}, 'normal'); }); $('a').mouseout (function() { $('.logo').animate ({opacity:'1'}, 'normal'); $('.menu li a:hover').fadeIn ('slow'); }); </script>

• C# Asynchronous Network IO and OutOfMemoryException

  - by The.Anti.9

  I'm working on a client/server application in C#, and I need to get Asynchronous sockets working so I can handle multiple connections at once. Technically it works the way it is now, but I get an OutOfMemoryException after about 3 minutes of running. MSDN says to use a WaitHandler to do WaitOne() after the socket.BeginAccept(), but it doesn't actually let me do that. When I try to do that in the code it says WaitHandler is an abstract class or interface, and I can't instantiate it. I thought maybe Id try a static reference, but it doesnt have teh WaitOne() method, just WaitAll() and WaitAny(). The main problem is that in the docs it doesn't give a full code snippet, so you can't actually see what their "wait handler" is coming from. its just a variable called allDone, which also has a Reset() method in the snippet, which a waithandler doesn't have. After digging around in their docs, I found some related thing about an AutoResetEvent in the Threading namespace. It has a WaitOne() and a Reset() method. So I tried that around the while(true) { ... socket.BeginAccept( ... ); ... }. Unfortunately this makes it only take one connection at a time. So I'm not really sure where to go. Here's my code: class ServerRunner { private Byte[] data = new Byte[2048]; private int size = 2048; private Socket server; static AutoResetEvent allDone = new AutoResetEvent(false); public ServerRunner() { server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint iep = new IPEndPoint(IPAddress.Any, 33333); server.Bind(iep); Console.WriteLine("Server initialized.."); } public void Run() { server.Listen(100); Console.WriteLine("Listening..."); while (true) { //allDone.Reset(); server.BeginAccept(new AsyncCallback(AcceptCon), server); //allDone.WaitOne(); } } void AcceptCon(IAsyncResult iar) { Socket oldserver = (Socket)iar.AsyncState; Socket client = oldserver.EndAccept(iar); Console.WriteLine(client.RemoteEndPoint.ToString() + " connected"); byte[] message = Encoding.ASCII.GetBytes("Welcome"); client.BeginSend(message, 0, message.Length, SocketFlags.None, new AsyncCallback(SendData), client); } void SendData(IAsyncResult iar) { Socket client = (Socket)iar.AsyncState; int sent = client.EndSend(iar); client.BeginReceive(data, 0, size, SocketFlags.None, new AsyncCallback(ReceiveData), client); } void ReceiveData(IAsyncResult iar) { Socket client = (Socket)iar.AsyncState; int recv = client.EndReceive(iar); if (recv == 0) { client.Close(); server.BeginAccept(new AsyncCallback(AcceptCon), server); return; } string receivedData = Encoding.ASCII.GetString(data, 0, recv); //process received data here byte[] message2 = Encoding.ASCII.GetBytes("reply"); client.BeginSend(message2, 0, message2.Length, SocketFlags.None, new AsyncCallback(SendData), client); } }

• One letter game problem?

  - by Alex K

  Recently at a job interview I was given the following problem: Write a script capable of running on the command line as python It should take in two words on the command line (or optionally if you'd prefer it can query the user to supply the two words via the console). Given those two words: a. Ensure they are of equal length b. Ensure they are both words present in the dictionary of valid words in the English language that you downloaded. If so compute whether you can reach the second word from the first by a series of steps as follows a. You can change one letter at a time b. Each time you change a letter the resulting word must also exist in the dictionary c. You cannot add or remove letters If the two words are reachable, the script should print out the path which leads as a single, shortest path from one word to the other. You can /usr/share/dict/words for your dictionary of words. My solution consisted of using breadth first search to find a shortest path between two words. But apparently that wasn't good enough to get the job :( Would you guys know what I could have done wrong? Thank you so much. import collections import functools import re def time_func(func): import time def wrapper(*args, **kwargs): start = time.time() res = func(*args, **kwargs) timed = time.time() - start setattr(wrapper, 'time_taken', timed) return res functools.update_wrapper(wrapper, func) return wrapper class OneLetterGame: def __init__(self, dict_path): self.dict_path = dict_path self.words = set() def run(self, start_word, end_word): '''Runs the one letter game with the given start and end words.

• Need to hide displayed div when I show others

  - by adrian collins

  I am stuck. I have a page with 3 buttons, the 3 buttons do a couple things - they change the style of a div, and they also show/hide a content div. The changing of the div style works fine, but I am having issues with the content div. If you land on the page and click the "Our Brands" tab, then click the other 2 tabs, it works fine. If you land on the page, and click "What's New" or "About Us" first, then the show/hide does not work correctly - it does not until you actually click on "Our Brands." http://www.adriancollins.net/clients/kennys/ Any help would be appreciated, I am a designer first, a developer about 9000th. Show/Hide Code <script type="text/javascript"> var _hidediv = null; function showdiv(id) { if(_hidediv) _hidediv(); var div = document.getElementById(id); div.style.display = 'block'; _hidediv = function () { div.style.display = 'none'; }; } </script> Tab Divs <div id="brand_button"><a href="#" onClick="showdiv('brands_content'); lower.className='blue';angle.className='blue_angle';return false"><img src="wp-content/uploads/2012/10/brands_button.png"></a></div> <div id="whatsnew_button"><a href="#" onClick="showdiv('new_content');lower.className='black';angle.className='black_angle';return false"><img src="wp-content/uploads/2012/10/whatsnew_button.png"></a></div> <div id="about_button"><a href="#" onClick="showdiv('about_content');lower.className='green';angle.className='green_angle';return false"><img src="wp-content/uploads/2012/10/about_button.png"></a></div> Content Divs <div id="brands_content">Content...</div> <div id="whats_content">Content...</div> <div id="about_content">Content...</div> CSS #brands_content { position: relative; display: block; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 12; } #new_content { position: relative; display: none; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 999; color: #fff; } #about_content { position: relative; display: none; width: 990px; top: 10px; height: auto; min-height: 800px; margin-left: auto; margin-top: 0px; margin-right: auto; border: 0px; padding: 0px 0px 0px 0px; z-index: 999; } Thanks

• Search Form in Responsive Design - Remove Search button on Mobile

  - by Kevin

  I'm working with a search box in the header of a responsive website. On desktop/tablet widths, there's a search input field and a styled 'search' button to the right. You can type in a search term and either click 'SEARCH' button or just hit enter on the keyboard with the same result. When you scale down to mobile widths, the search input field fills the width of the screen. The submit button falls below it. On a desktop, clicking the button or hitting enter activate the search. On an actual iphone phone, you can hit the 'SEARCH' button, but the native mobile keyboard that rises from the bottom of the screen has a search button where the enter/return key would normally be. It seems to know I'm in a form and the keyboard automatically gives me the option to kick off the search by basically hitting the ENTER key location....but it says SEARCH. So far so good. I figure I don't need the button in the header on mobile since it's already in the keyboard. Therefore, I'll hide the button on mobile widths and everything will be tighter and look better. So I added this to my CSS to hide it in mobile: #search-button {display: none;} But now the search doesn't work at all. On mobile, I don't get the option in the keyboard that showed up before and if I just hit enter, it doesn't work at all. On desktop at mobile width, hitting enter also not longer works. So clearly by hiding the submit/search button, the phone no longer gave me the native option to run the search. In addition, on the desktop at mobile width, even hitting enter inside the search input box also fails to launch the the search. Here's my search box: <form id="search-form" method="get" accept-charset="UTF-8, utf-8" action="search.php"> <fieldset> <div id="search-wrapper"> <label id="search-label" for="search">Item:</label> <input id="search" class="placeholder-color" name="item" type="text" placeholder="Item Number or Description" /> <button id="search-button" title="Go" type="submit"><span class="search-icon"></span></button> </div> </fieldset> </form> Here's what my CSS looks like: #search-wrapper { float: left; display: inline-block; position: relative; white-space: nowrap; } #search-button { display: inline-block; cursor: pointer; vertical-align: top; height: 30px; width: 40px; } @media only screen and (max-width: 639px) { #search-wrapper { display: block; margin-bottom: 7px; } #search-button { /* this didn't work....it hid the button but the search failed to load */ display: none;*/ } } So.....how can I hide this submit button when I'm on a mobile screen, but still let the search run from the mobile keyboard or just run by hitting enter when in the search input box. I was sure that putting display:none on the search button at mobile width would do the trick, but apparently not. Thanks...

• opening a fancybox from a drop down box and passing the selected value to it directly

  <select name="mySelectboxsituation_found" id="mySelectboxsituation_found"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> < a href="#" class="incidenttype" name="all" onClick="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"/>CLICK HERE < / a> function cleanUp(){ var subsituation_found1 = $("#fancybox- frame").contents().find('input:radio[name=incident_subcate]:checked').val(); } $(".incidenttype").fancybox({ 'width' : 900, 'height' : 600, 'autoScale': false, 'transitionIn': 'none', 'transitionOut': 'none', 'type': 'iframe', 'onCleanup': cleanUp ); }); clicking on "CLICK HERE" opens the fancybox and transfers the value selected in the drop down box. What I would like to do is open the fancy box when i change the value in the dropdown box...without having to click on the click here link.....i know it is posisble using something like _this....but i am not sure and am looking for some direction... ideally some thing like this ... <select name="mySelectboxsituation_found" id="mySelectboxsituation_found" onChange="JavaScript:var dropdown=document.getElementById('mySelectboxsituation_found');this.href='main_situation_found.php?incident_maincateid='+dropdown.options[dropdown.selectedIndex].value;return true;"> <option value="100">Firecall</option> <option value="200">FireAlarm</option> <option value="300">FireAlarm2</option> <option value="400">FireAlarm4</option> </select> does any have an idea how to do it....

• Session state provider and global.asax not interacting properly?

  - by yodaj007

  I'm experimenting with creating a crude, proof-of-concept session state store provider in ASP.Net. But I've got a problem and I'm not sure what to do about it. The website works properly when using the InProc provider. The Session_Start in global.asax is called on session creation as it should. But not if I implement my own provider. The Session_Start method from global.asax isn't being called at all if a new session is being created (that is, I delete the session state file). Am I missing something important here? public class TestSessionProvider : SessionStateStoreProviderBase { private const string ROOT = "c:\\projects\\sessions\\"; private const int TIMEOUT_MINUTES = 30; public string ApplicationName { get { return HostingEnvironment.ApplicationVirtualPath; } } private string GetFilename(string id) { string filename = String.Format("{0}_{1}.session", ApplicationName, id); char[] invalids = Path.GetInvalidPathChars(); for (int i = 0; i < invalids.Length; i++) { filename = filename.Replace(invalids[i], '_'); } return Path.Combine(ROOT, Path.GetFileName(filename)); } public override void Initialize(string name, NameValueCollection config) { if (config == null) throw new ArgumentNullException("config"); if (String.IsNullOrEmpty(name)) name = "Sporkalicious"; base.Initialize(name, config); } public override SessionStateStoreData CreateNewStoreData(HttpContext context, int timeout) { SessionStateItemCollection items = new SessionStateItemCollection(); HttpStaticObjectsCollection objects = SessionStateUtility.GetSessionStaticObjects(context); return new SessionStateStoreData(items, objects, TIMEOUT_MINUTES); } /// <summary> /// The CreateUninitializedItem method is used with cookieless sessions when the regenerateExpiredSessionId /// attribute is set to true, which causes SessionStateModule to generate a new SessionID value when an /// expired session ID is encountered. /// </summary> /// <param name="context"></param> /// <param name="id"></param> /// <param name="timeout"></param> public override void CreateUninitializedItem(HttpContext context, string id, int timeout) { FileStream fs = File.Open(GetFilename(id), FileMode.CreateNew, FileAccess.Write, FileShare.None); BinaryWriter writer = new BinaryWriter(fs); SessionStateItemCollection coll = new SessionStateItemCollection(); coll.Serialize(writer); fs.Flush(); fs.Close(); } public override SessionStateStoreData GetItem(HttpContext context, string id, out bool locked, out TimeSpan lockAge, out object lockId, out SessionStateActions actions) { return GetItemExclusive(context, id, out locked, out lockAge, out lockId, out actions); } public override SessionStateStoreData GetItemExclusive(HttpContext context, string id, out bool locked, out TimeSpan lockAge, out object lockId, out SessionStateActions actions) { locked = false; lockAge = TimeSpan.FromDays(1); lockId = 0; actions = SessionStateActions.None; if (!File.Exists(GetFilename(id))) { return null; } FileStream fs = File.Open(GetFilename(id), FileMode.Open, FileAccess.ReadWrite, FileShare.Read); BinaryReader reader = new BinaryReader(fs); SessionStateItemCollection coll = SessionStateItemCollection.Deserialize(reader); fs.Close(); return new SessionStateStoreData(coll, new HttpStaticObjectsCollection(), TIMEOUT_MINUTES); } public override void ReleaseItemExclusive(HttpContext context, string id, object lockId) { } public override void RemoveItem(HttpContext context, string id, object lockId, SessionStateStoreData item) { File.Delete(GetFilename(id)); } public override void ResetItemTimeout(HttpContext context, string id) { } public override void SetAndReleaseItemExclusive(HttpContext context, string id, SessionStateStoreData item, object lockId, bool newItem) { if (!File.Exists(GetFilename(id))) { CreateUninitializedItem(context, id, 10); } FileStream fs = File.Open(GetFilename(id), FileMode.Truncate, FileAccess.Write, FileShare.None); BinaryWriter writer = new BinaryWriter(fs); SessionStateItemCollection coll = (SessionStateItemCollection)item.Items; coll.Serialize(writer); fs.Flush(); fs.Close(); } public override bool SetItemExpireCallback(SessionStateItemExpireCallback expireCallback) { return false; } public override void InitializeRequest(HttpContext context){} public override void EndRequest(HttpContext context){} public override void Dispose(){} }

• Div width: auto and IE

  - by Andrew Heath

  I'm using the jQuery qTip to show individual users and their votes when an average rating is mousedover. qTip calls a PHP file which grabs all the users and votes for the item from the MySQL database and builds a 3 column table, which appears as the tooltip. In Firefox, the tooltip displays properly. In IE7 (haven't tested on IE8 yet), the tooltip is the proper height, but the width is only 2 or 3 characters - not the entire table. If I set the width of the div to a fixed number, say width: 300px; I can coax IE into displaying it properly. However, the length of my users' names varies considerably, and I'd rather not nail down the div to its maximum possible width and then have a crapload of whitespace when you look at an item voted on only by "Joe". Using width: auto; has no effect in IE7. Are there alternatives? Sorry if I've overlooked a similar question. I searched for a bit before posting but didn't find anything suitable. EDIT TO ADD CODE: <div style="-moz-border-radius: 0pt 0pt 0pt 0pt; position: absolute; width: 358px; display: none; top: 384.617px; left: 463.5px; z-index: 6000;" class="qtip qtip-defaults" qtip="0"> <div style="position: relative; overflow: hidden; text-align: left;" class="qtip-wrapper"> <div style="overflow: hidden; background: none repeat scroll 0% 0% white; border: 1px solid rgb(211, 211, 211);" class="qtip-contentWrapper"> <div class="qtip-content qtip-content" style="background: none repeat scroll 0% 0% white; color: rgb(17, 17, 17); overflow: hidden; text-align: left; padding: 5px 9px;"> <div id="WhoResults"> <table> <tbody> <tr> <td>guy1</td> <td>guy2</td> <td>guy3</td> </tr> <tr> <td>guy4</td> <td>guy5</td> <td>guy6</td> </tr> </tbody> </table> </div> </div> </div> </div> </div> I have applied no CSS styling. That's all been handled by qTip. I tried to format it as best I could. Thanks for any help you can provide.
