• How to get JSF2 working with Seam2

  - by Walter White

  Hi all, Is it possible to get JSF2 working on the latest production Seam release (2.2.1.GA)? I get this error on startup: javax.faces.view.facelets.FaceletException: Must have a Constructor that takes in a ComponentConfig at

• XNA Xbox 360 Content Manager Thread freezing Draw Thread

  - by Alikar

  I currently have a game that takes in large images, easily bigger than 1MB, to serve as backgrounds. I know exactly when this transition is supposed to take place, so I made a loader class to handle loading these large images in the background, but when I load the images it still freezes the main thread where the drawing takes place. Since this code runs on the 360 I move the thread to the 4th hardware thread, but that doesn't seem to help. Below is the class I am using. Any thoughts as to why my new content manager which should be in its own thread is interrupting the draw in my main thread would be appreciated. namespace FileSystem { /// <summary> /// This is used to reference how many objects reference this texture. /// Everytime someone references a texture we increase the iNumberOfReferences. /// When a class calls remove on a specific texture we check to see if anything /// else is referencing the class, if it is we don't remove it.

Does anyone know the possible reason? Thank you.

• Winform/Program and how to write array information to linklabels?!!?

  - by JB

  So my program works like this: using winforms, user enters ID number, using an array, based on the right id number, that student information and class schedule outputs in a message box! My question is how to take the 4 classes in the message box/array and write them to the linklabel text in form 2???? My Getschedule class contains the array and is listed below: namespace Eagle_Eye_Class_Finder { public class GetSchedule { IDnumber[] IDnumbers = new IDnumber[3]; public string GetDataFromNumber(string ID) { foreach (IDnumber IDCandidateMatch in IDnumbers) { if (IDCandidateMatch.ID == ID) { StringBuilder myData = new StringBuilder(); myData.AppendLine(IDCandidateMatch.Name); myData.AppendLine(": "); myData.AppendLine(IDCandidateMatch.ID); myData.AppendLine(IDCandidateMatch.year); myData.AppendLine(IDCandidateMatch.class1); myData.AppendLine(IDCandidateMatch.class2); myData.AppendLine(IDCandidateMatch.class3); myData.AppendLine(IDCandidateMatch.class4); //return myData; return myData.ToString(); } } return ""; } public GetSchedule() { IDnumbers[0] = new IDnumber() { Name = "Joshua Banks", ID = "900456317", year = "Senior", class1 = "TEET 4090", class2 = "TEET 3020", class3 = "TEET 3090", class4 = "TEET 4290" };

• jQuery Datatables throws error when dynamically created row headers

  - by JM4

  I am using the Datatables jquery plugin for one of my projects. For one in particular, the number of columns can vary based on how many children a consumer has (yes I realize normalization and proper technique would insert on another row but it is a client requirement).

• Java threads, wait time always 00:00:00-Producer/Consumer

  - by user3742254

  I am currently doing a producer consumer problem with a number of threads and have had to set priorities and waits to them to ensure that one thread, the security thread, runs last. I have managed to do this and I have managed to get the buffer working. The last thing that I am required to do is to show the wait time of threads that are too large for the buffer and to calculate the average wait time. I have included code to do so, but everything I run the program, the wait time is always returned as 00:00:00, and by extension, the average is returned as the same. I was speaking to one of my colleagues who said that it is not a matter of the code but rather a matter of the computer needing to work off of one processor, which can be adjusted in the task manager settings. He has an HP like myself but his program prints the wait time 180 times, whereas mine prints usually about 3-7 times and is only 00:00:01 on one instance before finishing when I have made the processor adjustments. My other colleague has an iMac and hers puts out an average of 42:00:34(42 minutes??) I am very confused about this because I can see no difference between our codes and like my colleague said, I was wondering is it a computer issue. I am obviously concerned as I wanted to make sure that my code correctly calculated an average wait time, but that is impossible to tell when the wait times always show as 00:00:00. To calculate the thread duration, including the time it entered and exited the buffer was done by using a timestamp import, and then subtracting start time from end time. Is my code correct for this issue or is there something which is missing? I would be very grateful for any solutions. Below is my code: My buffer class package com.Com813cw; import java.text.DateFormat; import java.text.SimpleDateFormat; /** * Created by Rory on 10/08/2014. */ class Buffer { private int contents, count = 0, process = 200;

• Failed to Install Xdebug

  - by burnt1ce

  've registered xdebug in php.ini (as per http://xdebug.org/docs/install) but it's not showing up when i run "php -m" or when i get a test page to run "phpinfo()". I've just installed the latest version of XAMPP. I've used both "zend_extention" and "zend_extention_ts" to specify the path of the xdebug dll. I ensured that my apache server restarted and used the latest change of my php.ini by executing "httpd -k restart". Can anyone provide any suggestions in getting xdebug to show up? Here are the contents of my php.ini file. [PHP] ;;;;;;;;;;;;;;;;;;; ; About php.ini ; ;;;;;;;;;;;;;;;;;;; ; PHP's initialization file, generally called php.ini, is responsible for ; configuring many of the aspects of PHP's behavior. ; PHP attempts to find and load this configuration from a number of locations. ; The following is a summary of its search order: ; 1. SAPI module specific location. ; 2. The PHPRC environment variable. (As of PHP 5.2.0) ; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0) ; 4. Current working directory (except CLI) ; 5. The web server's directory (for SAPI modules), or directory of PHP ; (otherwise in Windows) ; 6. The directory from the --with-config-file-path compile time option, or the ; Windows directory (C:\windows or C:\winnt) ; See the PHP docs for more specific information. ; http://php.net/configuration.file ; The syntax of the file is extremely simple. Whitespace and Lines ; beginning with a semicolon are silently ignored (as you probably guessed). ; Section headers (e.g. [Foo]) are also silently ignored, even though ; they might mean something in the future. ; Directives following the section heading [PATH=/www/mysite] only ; apply to PHP files in the /www/mysite directory. Directives ; following the section heading [HOST=www.example.com] only apply to ; PHP files served from www.example.com. Directives set in these ; special sections cannot be overridden by user-defined INI files or ; at runtime. Currently, [PATH=] and [HOST=] sections only work under ; CGI/FastCGI. ; http://php.net/ini.sections ; Directives are specified using the following syntax: ; directive = value ; Directive names are *case sensitive* - foo=bar is different from FOO=bar. ; Directives are variables used to configure PHP or PHP extensions. ; There is no name validation. If PHP can't find an expected ; directive because it is not set or is mistyped, a default value will be used. ; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one ; of the INI constants (On, Off, True, False, Yes, No and None) or an expression ; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a ; previously set variable or directive (e.g. ${foo}) ; Expressions in the INI file are limited to bitwise operators and parentheses: ; | bitwise OR ; ^ bitwise XOR ; & bitwise AND ; ~ bitwise NOT ; ! boolean NOT ; Boolean flags can be turned on using the values 1, On, True or Yes. ; They can be turned off using the values 0, Off, False or No. ; An empty string can be denoted by simply not writing anything after the equal ; sign, or by using the None keyword: ; foo = ; sets foo to an empty string ; foo = None ; sets foo to an empty string ; foo = "None" ; sets foo to the string 'None' ; If you use constants in your value, and these constants belong to a ; dynamically loaded extension (either a PHP extension or a Zend extension), ; you may only use these constants *after* the line that loads the extension. ;;;;;;;;;;;;;;;;;;; ; About this file ; ;;;;;;;;;;;;;;;;;;; ; PHP comes packaged with two INI files. One that is recommended to be used ; in production environments and one that is recommended to be used in ; development environments. ; php.ini-production contains settings which hold security, performance and ; best practices at its core. But please be aware, these settings may break ; compatibility with older or less security conscience applications. We ; recommending using the production ini in production and testing environments. ; php.ini-development is very similar to its production variant, except it's ; much more verbose when it comes to errors. We recommending using the ; development version only in development environments as errors shown to ; application users can inadvertently leak otherwise secure information. ;;;;;;;;;;;;;;;;;;; ; Quick Reference ; ;;;;;;;;;;;;;;;;;;; ; The following are all the settings which are different in either the production ; or development versions of the INIs with respect to PHP's default behavior. ; Please see the actual settings later in the document for more details as to why ; we recommend these changes in PHP's behavior. ; allow_call_time_pass_reference ; Default Value: On ; Development Value: Off ; Production Value: Off ; display_errors ; Default Value: On ; Development Value: On ; Production Value: Off ; display_startup_errors ; Default Value: Off ; Development Value: On ; Production Value: Off ; error_reporting ; Default Value: E_ALL & ~E_NOTICE ; Development Value: E_ALL | E_STRICT ; Production Value: E_ALL & ~E_DEPRECATED ; html_errors ; Default Value: On ; Development Value: On ; Production value: Off ; log_errors ; Default Value: Off ; Development Value: On ; Production Value: On ; magic_quotes_gpc ; Default Value: On ; Development Value: Off ; Production Value: Off ; max_input_time ; Default Value: -1 (Unlimited) ; Development Value: 60 (60 seconds) ; Production Value: 60 (60 seconds) ; output_buffering ; Default Value: Off ; Development Value: 4096 ; Production Value: 4096 ; register_argc_argv ; Default Value: On ; Development Value: Off ; Production Value: Off ; register_long_arrays ; Default Value: On ; Development Value: Off ; Production Value: Off ; request_order ; Default Value: None ; Development Value: "GP" ; Production Value: "GP" ; session.bug_compat_42 ; Default Value: On ; Development Value: On ; Production Value: Off ; session.bug_compat_warn ; Default Value: On ; Development Value: On ; Production Value: Off ; session.gc_divisor ; Default Value: 100 ; Development Value: 1000 ; Production Value: 1000 ; session.hash_bits_per_character ; Default Value: 4 ; Development Value: 5 ; Production Value: 5 ; short_open_tag ; Default Value: On ; Development Value: Off ; Production Value: Off ; track_errors ; Default Value: Off ; Development Value: On ; Production Value: Off ; url_rewriter.tags ; Default Value: "a=href,area=href,frame=src,form=,fieldset=" ; Development Value: "a=href,area=href,frame=src,input=src,form=fakeentry" ; Production Value: "a=href,area=href,frame=src,input=src,form=fakeentry" ; variables_order ; Default Value: "EGPCS" ; Development Value: "GPCS" ; Production Value: "GPCS" ;;;;;;;;;;;;;;;;;;;; ; php.ini Options ; ;;;;;;;;;;;;;;;;;;;; ; Name for user-defined php.ini (.htaccess) files.

• Dynamic DataGrid columns in WPF DataGrid based on the underlying set of data (and their type)

  - by StatsMan

  Hello everyone, I've got kind of a conceptual question. I am in the process of wrapping some statistics classes I wrote into WPF. For that I have two DataGrid(-Views, currently in WinForms). In one DataGrid each row represents a column in the other. There I can set-up different variables (as in mathematical/statistical variables) with fields like "Header", "DataType", "ValidationBehaviour", "DisplayType". There I can also set-up how it should be displayed. Some Columns can automatically be set to ComboBoxColumns, some TextBoxColumns, and so on and so forth. So, now once I've set-up these Columns I can go to the other grid and enter my data. I may, for instance, have generated (in grid 1) one Column called "Annual Gross Salary" with input of numerical values. Another Column called "Education" with "0=NoEducation", "1=College Level", "3=Universitary" etc. These labels are displayed as text in the combobox and my statistics engine behind then selects the respective value (0-3) for calculations (i.e. ordinal, nominal variables). Sooo. In WinForms I could basically generate all the columns by hand in code and then add my data in the respective cells/rows. Now in WPF I thought that must be easy to realise. However, yesterday I got started with ICustomPropertyDescriptor which (maybe I was too thick) didn't give me the results I was looking for. Basically, I just need to be able to dynamically generate columns (and rows) with different Layout, Controls (ComboBox, simple Input, DateTimes) based on the data that I have. But I don't really know how to go about it? So here in summary: DataGrid 1 Purpose is to display columns that have been specified in DataGrid 2 In rows, the user can add any kind of data in the rows below the columns that is allowed as to the columns specifications DataGrid 2 Each row in this grid represents a column in DataGrid 1 Contains fields like Name/Header, DataType, Validation Behaviour, Default Value, Data Formatting, etc. Also contains a function to be able to set-up how it should be displayed. The user can select from, for instance, ComboBoxColumn (and also add the available options), DateTime, normal TextBox, CheckBox etc. After finishing adding a row it will automatically appear as a new column in DataGrid 1 I'd appreciate any kind of pointer into the right direction. Thanks very, very much in advance! :)

• Maintain cookie session in Android

  - by datguywhowanders

  Okay, I have an android application that has a form in it, two EditText, a spinner, and a login button. The user selects the service from the spinner, types in their user name and password, and clicks login. The data is sent via POST, a response is returned, it's handled, a new webview is launched, the html string generated form the response is loaded, and I have the home page of whatever service the user selected. That's all well and good. Now, when the user clicks on a link, the login info can't be found, and the page asks the user to login again. My login session is being dropped somewhere, and I'm not certain how to pass the info from the class that controls the main part of my app to the class that just launches the webview activity. The on click handler from the form login button: private class FormOnClickListener implements View.OnClickListener { public void onClick(View v) { String actionURL, user, pwd, user_field, pwd_field; actionURL = "thePageURL"; user_field = "username"; //this changes based on selections in a spinner pwd_field = "password"; //this changes based on selections in a spinner user = "theUserLogin"; pwd = "theUserPassword"; List<NameValuePair> myList = new ArrayList<NameValuePair>(); myList.add(new BasicNameValuePair(user_field, user)); myList.add(new BasicNameValuePair(pwd_field, pwd)); HttpParams params = new BasicHttpParams(); DefaultHttpClient client = new DefaultHttpClient(params); HttpPost post = new HttpPost(actionURL); HttpResponse response = null; BasicResponseHandler myHandler = new BasicResponseHandler(); String endResult = null; try { post.setEntity(new UrlEncodedFormEntity(myList)); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } try { response = client.execute(post); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { endResult = myHandler.handleResponse(response); } catch (HttpResponseException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } List cookies = client.getCookieStore().getCookies(); if (!cookies.isEmpty()) { for (int i = 0; i < cookies.size(); i++) { cookie = cookies.get(i); } } Intent myWebViewIntent = new Intent(MsidePortal.this, MyWebView.class); myWebViewIntent.putExtra("htmlString", endResult); myWebViewIntent.putExtra("actionURL", actionURL); startActivity(myWebViewIntent); } } And here is the webview class that handles the response display: public class MyWebView extends android.app.Activity{ private class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.web); MyWebViewClient myClient = new MyWebViewClient(); WebView webview = (WebView)findViewById(R.id.mainwebview); webview.getSettings().setBuiltInZoomControls(true); webview.getSettings().setJavaScriptEnabled(true); webview.setWebViewClient(myClient); Bundle extras = getIntent().getExtras(); if(extras != null) { // Get endResult String htmlString = extras.getString("htmlString"); String actionURL = extras.getString("actionURL"); Cookie sessionCookie = MsidePortal.cookie; CookieSyncManager.createInstance(this); CookieManager cookieManager = CookieManager.getInstance(); if (sessionCookie != null) { cookieManager.removeSessionCookie(); String cookieString = sessionCookie.getName() + "=" + sessionCookie.getValue() + "; domain=" + sessionCookie.getDomain(); cookieManager.setCookie(actionURL, cookieString); CookieSyncManager.getInstance().sync(); } webview.loadDataWithBaseURL(actionURL, htmlString, "text/html", "utf-8", actionURL); } } } I've had mixed success implementing that cookie solution. It seems to work for one service I log into that I know keeps the cookies on the server (old, archaic, but it works and they don't want to change it.) The service I'm attempting now requires the user to keep cookies on their local machine, and it does not work with this setup. Any suggestions?

• How to configure LocalSessionFactoryBean to release connections after transaction end?

  - by peter

  I am testing an application (Spring 2.5, Hibernate 3.5.0 Beta, Atomikos 3.6.2, and Postgreql 8.4.2) with the configuration for the DAO listed below. The problem that I see is that the pool of 10 connections with the dataSource gets exhausted after the 10's transaction. I know 'hibernate.connection.release_mode' has no effect unless the session is obtained with openSession rather then using a contextual session. I am wandering if anyone has found a way to configure the LocalSessionFactoryBean to release connections after any transaction.

• XSL testing empty strings with <xsl:if> and sorting

  - by AdRock

  I am having trouble with a template that has to check 3 different nodes and if they are not empty, print the data I am using for each node then doing the output but it is not printing anything. It is like the test returns zero. I have selected the parent node of each node i want to check the length on as the template match but it still doesn't work. Another thing, how do i sort the list using . I tried using this but i get an error about loading the stylesheet. If i take out the sort it works <xsl:template match="folktask/member"> <xsl:if test="user/account/userlevel='3'"> <xsl:sort select="festival/event/datefrom"/> <div class="userdiv"> <xsl:apply-templates select="user"/> <xsl:apply-templates select="festival"/> </div> </xsl:if> </xsl:template> <xsl:template match="festival"> <xsl:apply-templates select="contact"/> </xsl:template> This should hopefully finish all my stylesheets. This is the template I am calling <xsl:template match="contact"> <xsl:if test="string-length(contelephone)!=0"> <div class="small bold">TELEPHONE:</div> <div class="large"> <xsl:value-of select="contelephone/." /> </div> </xsl:if> <xsl:if test="string-length(conmobile)!=0"> <div class="small bold">MOBILE:</div> <div class="large"> <xsl:value-of select="conmobile/." /> </div> </xsl:if> <xsl:if test="string-length(fax)!=0"> <div class="small bold">FAX:</div> <div class="large"> <xsl:value-of select="fax/." /> </div> </xsl:if> </xsl:template> and a section of my xml.

• CruiseControl.NET: using $(CCNetLabel ) inside ccnet.config file

  - by minty

  When calling external processes like MSBuild cruise control sets environment variables. One of values is CCNetLabel. it holds the value of the current projects label. I want to use the same values in ccnet config itself but when I try ccnet config has a problem. I get the following error: [CCNet Server:ERROR] INTERNAL ERROR: Reference to unknown symbol CCNetLabel ---------- ThoughtWorks.CruiseControl.Core.Config.Preprocessor.EvaluationException: Reference to unknown symbol CCNetLabel at ThoughtWorks.CruiseControl.Core.Config.Preprocessor.ConfigPreprocessorEnvironment._GetConstantDef(String name) at ThoughtWorks.CruiseControl.Core.Config.Preprocessor.ConfigPreprocessorEnvironment.eval_text_constant(String name) ..... ---------- I actually want to append the CCNetLabel to another variable so I need to access the property in ccnet.config. is there a different way to reference these variables?

• How to print PCL Directly to the printer? Vb.net VS 2010

  - by Justin

  Good day, I've been trying to upgrade an old Print Program that prints raw pcl directly to the printer. The print program takes a PCL Mask and a PCL Batch Spool File (just pcl with page turn commands, I think) merges them and sends them off to the printer. I'm able to send to the Printer a file stream of PCL but I get mixed results and i do not understand why printing is so difficult under .net. I mean yes there is the PrintDocument class, but to print PCL... Let's just say I'm ready to detach my printer from the network and burn it a live. Here is my class PrintDirect (rather a hybrid class) Imports System Imports System.Text Imports System.Runtime.InteropServices <StructLayout(LayoutKind.Sequential)> _ Public Structure DOCINFO <MarshalAs(UnmanagedType.LPWStr)> _ Public pDocName As String <MarshalAs(UnmanagedType.LPWStr)> _ Public pOutputFile As String <MarshalAs(UnmanagedType.LPWStr)> _ Public pDataType As String End Structure 'DOCINFO Public Class PrintDirect <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=False, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function OpenPrinter(ByVal pPrinterName As String, ByRef phPrinter As IntPtr, ByVal pDefault As Integer) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=False, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function StartDocPrinter(ByVal hPrinter As IntPtr, ByVal Level As Integer, ByRef pDocInfo As DOCINFO) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function StartPagePrinter(ByVal hPrinter As IntPtr) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Ansi, ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function WritePrinter(ByVal hPrinter As IntPtr, ByVal data As String, ByVal buf As Integer, ByRef pcWritten As Integer) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function EndPagePrinter(ByVal hPrinter As IntPtr) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function EndDocPrinter(ByVal hPrinter As IntPtr) As Long End Function <DllImport("winspool.drv", CharSet:=CharSet.Unicode, ExactSpelling:=True, CallingConvention:=CallingConvention.StdCall)> _ Public Shared Function ClosePrinter(ByVal hPrinter As IntPtr) As Long End Function 'Helps uses to work with the printer Public Class PrintJob ''' <summary> ''' The address of the printer to print to.

• idioms for returning multiple values in shell scripting

  - by Wang

  Are there any idioms for returning multiple values from a bash function within a script? http://tldp.org/LDP/abs/html/assortedtips.html describes how to echo multiple values and process the results (e.g., example 35-17), but that gets tricky if some of the returned values are strings with spaces in. A more structured way to return would be to assign to global variables, like foo () { FOO_RV1="bob" FOO_RV2="bill" } foo echo "foo returned ${FOO_RV1} and ${FOO_RV2}" I realize that if I need re-entrancy in a shell script I'm probably doing it wrong, but I still feel very uncomfortable throwing global variables around just to hold return values. Is there a better way? I would prefer portability, but it's probably not a real limitation if I have to specify #!/bin/bash.

• How to write php->mysql queries?

  - by Bluemagica

  Is there any good tutorial that has all the basic rules for writing queries to store $_Post vars from php to mysql? Like when to use backticks and singleqoutes, and how to safely write code with functions like get_magic_quotes_gpc()? Another thing is, assuming there is no javascript validation(since the user can easily turn it off), how should I handle empty form fields being sent as empty $_post variables and throwing errors? Do I have to use isset() call on all the post variables? What is the best way to handle users turning off javascript validation on a form?

You can cancel setup at any time by typing 'cancelSetup' Thankyou""" #Step 1 (Name): print print """Step 1 of 7: Type in a name for your PotatoHead: """ inputPHName = raw_input('|Enter Name:|') if inputPHName == 'cancelSetup': sys.exit() #Step 2 (Gender): print print """Step 2 of 7: Choose the gender of your PotatoHead: input either 'm' or 'f' """ inputPHGender = raw_input('|Enter Gender:|') if inputPHGender == 'cancelSetup': sys.exit() #Step 3 (Colour): print print """Step 3 of 7: Choose the colour your PotatoHead will be: Only Red, Blue, Green and Yellow are currently supported """ inputPHColour = raw_input('|Enter Colour:|') if inputPHColour == 'cancelSetup': sys.exit() #Step 4 (Favourite Thing): print print """Step 4 of 7: Type your PotatoHead's favourite thing: """ inputPHFavThing = raw_input('|Enter Favourite Thing:|') if inputPHFavThing == 'cancelSetup': sys.exit() # Step 5 (First Toy): print print """Step 5 of 7: Choose a first toy for your PotatoHead: """ inputPHFirstToy = raw_input('|Enter First Toy:|') if inputPHFirstToy == 'cancelSetup': sys.exit() #Step 6 (Check stats): while 1: print print """Step 6 of 7: Check the following details to make sure that they are correct: """ print print """Name:\t\t\t""" + inputPHName + """ Gender:\t\t\t""" + inputPHGender + """ Colour:\t\t\t""" + inputPHColour + """ Favourite Thing:\t""" + inputPHFavThing + """ First Toy:\t\t""" + inputPHFirstToy + """ """ print print "Enter 'y' or 'n'" inputMCheckStats = raw_input('|Is this information correct?|') if inputMCheckStats == 'cancelSetup': sys.exit() elif inputMCheckStats == 'y': break elif inputMCheckStats == 'n': print "Re-enter info: ..." print break else: "The value you entered was incorrect, please re-enter your choice" if inputMCheckStats == 'y': break #Step 7 (Define variables for the creation of the PotatoHead): MFCreatePH = [] print print """Step 7 of 7: Your PotatoHead will now be created...

Then it is passed to another function that was imported from another module from potatohead import * ... welcomeMessage() MCreatePH = startGame() myPotatoHead = PotatoHead(MCreatePH) the code for the PotatoHead object is in the potatohead.py module which was imported above, and is as follows: class PotatoHead: #Initialise the PotatoHead object: def __init__(self, data): self.data = data #Takes the data from the start new game function - see main.py #Defines the PotatoHead starting attributes: self.name = data[0] self.gender = data[1] self.colour = data[2] self.favouriteThing = data[3] self.firstToy = data[4] self.age = '0.0' self.education = [self.eduScience, self.eduEnglish, self.eduMaths] = '0.0', '0.0', '0.0' self.fitness = '0.0' self.happiness = '10.0' self.health = '10.0' self.hunger = '0.0' self.tiredness = 'Not in this version' self.toys = [] self.toys.append(self.firstToy) self.time = '0' #Sets data lists for saving, loading and general use: self.phData = (self.name, self.gender, self.colour, self.favouriteThing, self.firstToy) self.phAdvData = (self.name, self.gender, self.colour, self.favouriteThing, self.firstToy, self.age, self.education, self.fitness, self.happiness, self.health, self.hunger, self.tiredness, self.toys) However, when I run the program this error appears: Traceback (most recent call last): File "/Users/Jasper/Documents/Programming/Potato Head Game/Current/main.py", line 158, in <module> myPotatoHead = PotatoHead(MCreatePH) File "/Users/Jasper/Documents/Programming/Potato Head Game/Current/potatohead.py", line 15, in __init__ self.name = data[0] TypeError: 'NoneType' object is unsubscriptable What am i doing wrong? -----EDIT----- The program finishes as so: Step 7 of 7: Your PotatoHead will now be created...

• Objective-C: how to prevent abstraction leaks

  - by iter

  I gather that in Objective-C I must declare instance variables as part of the interface of my class even if these variables are implementation details and have private access. In "subjective" C, I can declare a variable in my .c file and it is not visible outside of that compilation unit. I can declare it in the corresponding .h file, and then anyone who links in that compilation unit can see the variable. I wonder if there is an equivalent choice in Objective-C, or if I must indeed declare every ivar in the .h for my class. Ari.

  I upgraded my Ubuntu server to 14.04 and Apache 2.4.7. Now my images don't load and console yields net::ERR_INCOMPLETE_CHUNKED_ENCODING.

This means that # the standard Auth/DBMAuth methods can be used for access control. The # user name is the `one line' version of the client's X.509 certificate. # Note that no password is obtained from the user. Every entry in the user # file needs this password: `xxj31ZMTZzkVA'. # o ExportCertData: # This exports two additional environment variables: SSL_CLIENT_CERT and # SSL_SERVER_CERT. These contain the PEM-encoded certificates of the # server (always existing) and the client (only existing when client # authentication is used). This can be used to import the certificates # into CGI scripts. # o StdEnvVars: # This exports the standard SSL/TLS related `SSL_*' environment variables. # Per default this exportation is switched off for performance reasons, # because the extraction step is an expensive operation and is usually # useless for serving static content. So one usually enables the # exportation for CGI and SSI requests only. # o StrictRequire: # This denies access when "SSLRequireSSL" or "SSLRequire" applied even # under a "Satisfy any" situation, i.e. when it applies access is denied # and no other module can change it. # o OptRenegotiate: # This enables optimized SSL connection renegotiation handling when SSL # directives are used in per-directory context. #SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire #<FilesMatch "\.(cgi|shtml|phtml|php)$"> # SSLOptions +StdEnvVars #</FilesMatch> # SSL Protocol Adjustments: # The safe and default but still SSL/TLS standard compliant shutdown # approach is that mod_ssl sends the close notify alert but doesn't wait for # the close notify alert from client. When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this. #BrowserMatch ".*MSIE.*" \ # nokeepalive ssl-unclean-shutdown \ # downgrade-1.0 force-response-1.0 </VirtualHost> </IfModule> logs Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.3 OpenSSL/1.0.1f (internal dummy connection) 127.0.0.1 - - [25/Aug/2014:13:09:53 +0300] "GET /img/header/top-nav-separator.png HTTP/1.1" 200 462 "https://localhost/art" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.132 Safari/537.36"
