Mapping of memory addresses to physical modules in Windows XP

- by Josef Grahn

I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

CURL & web.py: transfer closed with outstanding read data remaining

- by Richard J

Hi Folks, I have written a web.py POST handler, thus: import web urls = ('/my', 'Test') class Test: def POST(self): return "Here is your content" app = web.application(urls, globals()) if __name__ == "__main__": app.run() When I interact with it using Curl from the command line I get different responses depending on whether I post it any data or not: curl -i -X POST http://localhost:8080/my HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:42:41 GMT Server: CherryPy/3.1.2 WSGI Server Here is your content (Posting of no data to the server gives me back the "Here is your content" string) curl -i -X POST --data-binary "@example.zip" http://localhost:8080/my HTTP/1.1 100 Content-Length: 0 Content-Type: text/plain HTTP/1.1 200 OK Transfer-Encoding: chunked Date: Thu, 06 Jan 2011 16:43:47 GMT Server: CherryPy/3.1.2 WSGI Server curl: (18) transfer closed with outstanding read data remaining (Posting example.zip to the server results in this error) I've scoured the web.py documentation (what there is of it), and can't find any hints as to what might be going on here. Possibly something to do with 100 continue? I tried writing a python client which might help clarify: h1 = httplib.HTTPConnection('localhost:8080') h1.request("POST", "http://localhost:8080/my", body, headers) print h1.getresponse() body = the contents of the example.zip, and headers = empty dictionary. This request eventually timed out without printing anything, which I think exonerates curl from being the issue, so I believe something is going on in web.py which isn't quite right (or at least not sufficiently clear) Any web.py experts got some tips? Cheers, Richard

Why can I run JUnit tests for my Spring project, but not a main method?

- by FarmBoy

I am using JDBC to connect to MySQL for a small application. In order to test without altering the real database, I'm using HSQL in memory for JUnit tests. I'm using Spring for DI and DAOs. Here is how I'm configuring my HSQL DataSource <bean id="mockDataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:mem:mockSeo"/> <property name="username" value="sa"/> </bean> This works fine for my JUnit tests which use the mock DB. But when I try to run a main method, I find the following error: Error creating bean with name 'mockDataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.hsqldb.jdbcDriver] I'm running from Eclipse, and I'm using the Maven plugin. Is there a reason why this would work as a Test, but not as a main()? I know that the main method itself is not the problem, because it works if I remove all references to the HSQL DataSource from my Spring Configuration file.

WPF TextBlock Binding to DependencyProperty

- by Bill Campbell

Hi, I have what I believe to be about one of the most simple cases of attempting to bind a view to a dependencyproperty in the view model. It seems that the initial changes are reflected in the view but other changes to the DP do not update the view's TextBlock. I'm probably just missing something simple but I just can't see what it is. Please take a look... My XAML has a status bar on the bottom of the window. I want to bind to the DP "VRAStatus". <StatusBar x:Name="sbar" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" VerticalAlignment="Bottom" Background="LightBlue" Opacity="0.4" DockPanel.Dock="Bottom" > <StatusBarItem> <TextBlock x:Name="statusBar" Text="{Binding VRAStatus}" /> </StatusBarItem> <StatusBarItem> <Separator Style="{StaticResource StatusBarSeparatorStyle}"/> </StatusBarItem> </StatusBar> My viewmodel has the DP defined: public string VRAStatus { get { return (string)GetValue(VRAStatusProperty); } set { SetValue(VRAStatusProperty, value); } } // Using a DependencyProperty as the backing store for VRAStatus. public static readonly DependencyProperty VRAStatusProperty = DependencyProperty.Register("VRAStatus", typeof(string), typeof(PenskeRouteAssistViewModel),new PropertyMetadata(string.Empty)); Then, in my code I set the DP: VRAStatus = "Test Message..."; Is there something obvious here that I am missing? In my constructor for the viewmodel I set the DP like this: VRAStatus = "Ready"; I never get the Test Message to display. Please Help. thanks in advance! Bill

In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

- by Navi

I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

DNS PTR record when domain on shared IP address

- by Marco Demaio

Hello, I own a typical shared IP hosting plan and domain. I can modify the DNS of the domain from the control panel. The mailserver shares the same IP address, so my typical DNS config is: www.mydomain.com A -> IP mydomain.com A -> IP ftp.mydomain.com A -> IP mail.mydomain.com A -> IP mydomain.com MX(10) -> IP I read some Q&A on this site where they suggest to add PTR record mainly for mailserver. I would like to add PTR record to my domain, I have got two questions: 1) can PTR record be added even if the hosting/mailserver are on a shared IP address? Or do I need a dedicated IP. 2) How do I setup PTR record, I mean does it look like A record: mydomain.com (PTR) -> myip

How to properly combine two files in XAML in Microsoft Blend?

- by MartyIX

Hello, I have a test project with the file MainWindow.xaml with the content: <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" xmlns:view="clr-namespace:Sokoban.View;assembly=Solvers" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <ad:DockingManager x:Name="dockingManager"> <ad:ResizingPanel Orientation="Vertical"> <view:Solvers x:Name="solvers" diag:PresentationTraceSources.TraceLevel="High" />   </ad:ResizingPanel> </ad:DockingManager> </Window> and in another project I have the file Solvers.xaml: <ad:DocumentPane x:Class="Sokoban.View.Solvers" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Name="GamesDocumentPane" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> </ad:DocumentPane> When I open my Visual Studio solution in Microsoft Blend 4 then I see the error: InvalidOperationException: DocumentPane must be put under a DockingManager! when I open either MainWindow.xaml or Solvers.xaml. It is all right in Solvers.xaml because there really is no DockingManager but MainWindow.xaml should work, shouldn't it? How to solve the problem? Note: It seems to me that the files are processed separately and because the file Solvers.xaml contains the error the MainWindow.xaml file also contains the very same error. Note 2: XAML files use AvalonDock library Is there a way how to say that Solvers.xaml is only an extension of another file? Thank you for any help!

PHP: Echo function output in function-line, not line of function call

- by Brill

I have a problem with my self-coded template system. The content is inserted by Include(). Now I need to add a meta redirect to one page. I know, meta redirect is not the safest way, but I need it because of it's delay possibility. Now i'm looking for a way to influence the wrapping page (template) by the wrapped page (content). So I thought a function can do this job. <?php function test($testvar){ echo $testvar;} ?> <hr /> <?php test("testtext"); ?> Of course the text echos in the line of the function call, not in the function line. Is there a way to make the function echo in the line of the function itself? In this case above the horizontal rule, not below? Of course every other best pratice for this "template problem" ist welcome! THX

Header Setup in SOAP with ASP.NET 3.5 WCF

- by Adam

I'm pretty new to SOAP so go easy on me. I'm trying to setup a SOAP service that accepts the following header format: <soap:Header> <wsse:Security> <wsse:UsernameToken wsu:Id='SecurityToken-securityToken'> <wsse:Username>Username</wsse:Username> <wsse:Password>Password</wsse:Password> <wsu:Created>Timestamp</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soap:Header> The application I'm incorporating this service into is an ASP.NET 3.5 web application and I've already setup a SOAP endpoint using WCF. I've setup a basic service to make sure the WCF works and it works fine (disregarding the header). I heard that the above format follows WS-Security so I added WSHttpBinding in the web.config: <service name="Nexternal.Service.XMLTools.VNService" behaviorConfiguration="VNServiceBehavior">  <endpoint address="" binding="wsHttpBinding" contract="Nexternal.Service.XMLTools.IVNService"/> </service> I downloaded a test harness (soapUI) and pasted in a test message with the above header and it came back with a 400 Bad Request error. ...for what it's worth, I'm running Visual Studio 2008 using IIS7. I feel like I'm going in circles so any help would be awesome. Thanks in advance.

Help me a routing server on Windows XP

- by Lu Lu

I am developing client/server applications and need to test them on Internet environment. However, I only have one PC without connecting the public internet, so I have a plan to simulate a virtual internet environment on my PC. I think I will install the virtual machines for my purpose, but I can install only one machine because of my slowly PC. At the moment, my PC has 2 machines: the host machine (use Windows XP) & the virtual machine (use Windows Server 2003 Ent). Each machine will have 2 network adapter (host-only & internal), and in 2 network adapters, the internal adapter is private on each machine, and host-only adapters are connected together. With Windows 2003, routing server is ok, but I wonder on Windows XP, are there any routing server product? Please help me. Thanks.

Retrieve Flash file post in ASP.NET

Question: In ASP.NET, I retrieve a JPEG-file as Flash post data like this Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.ContentType = "text/plain" ' Retrieve a bytearray from the post buffer Dim myBuffer As Byte() = context.Request.BinaryRead(Convert.ToInt32(context.Request.InputStream.Length)) System.IO.File.WriteAllBytes("c:\temp\test.jpg", myBuffer) End Sub In Flash, I send it to an asp.net handler like this var jpgSource:BitmapData = cPrint.TakeSnapshot(MovieClip(cGlobals.ccPlanZoomView)); var bmpThisBitmap:Bitmap = new Bitmap(jpgSource); var nQuality:Number = 100; var jpgEncoder:JPGEncoder = new JPGEncoder(nQuality); var jpgStream:ByteArray = jpgEncoder.encode(jpgSource); var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream"); // Make sure to use the correct path to jpg_encoder_download.php var strFileName:String="test.jpg"; var jpgURLRequest:URLRequest = new URLRequest("http://localhost/raumplaner_new/raumplaner_new/cgi-bin/SavePDF.ashx"); //var scriptVars:URLVariables = new URLVariables(); //scriptVars.fn = strFileName; //var myarr:Array= new Array(); //myarr.push(jpgStream); //scriptVars.Files = myarr; jpgURLRequest.requestHeaders.push(header); jpgURLRequest.method = URLRequestMethod.POST; //jpgURLRequest.data = scriptVars; jpgURLRequest.data = jpgStream; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; loader.load(jpgURLRequest); It works but I want to send a few additional variables along, via scriptVars (commented out here). How do I retrieve the JPEG file in that case ? Because if I use parameters, there is no more BinaryRead... Aspecially, how would I read an array of jpeg files (several files) ?

Call Init from XUL after Page Loads (Firefox add-on)

- by mattyboy123

Hi all, I've been working on some code in js/html and it works great. I'm now trying to package it into an add-on for Firefox, and having some issues getting the XUL document correct. PLAIN OLD HTML/JS In my html test file between the <head></head> I have: <script type="text/javascript" src="js/MyCode.js"></script> At the end of the test file before the </body> I have: <script type="text/javascript">MyCode.Static.Init();</script> FIREFOX ADD-ON: OVERLAY.XUL In an overlay.xul file in the extension package I have : <?xml version="1.0"?> <overlay id="mycode" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://mycode/content/MyCode.js"></script> <script> window.addEventListener("load", function () { gBrowser.addEventListener("load",MyCode.Static.Init,true); }, false); </script> </overlay> This does not seem to enter the method, but then again I'm not even sure if I've got the listeners firing properly. Would this be the correct way to duplicate what I was doing in plain old html/js ?

Apache2 alias in virtual host

- by 0x7c00

I have multiple virtual host in one server and plan to has some alias setup in one virtualhost. So I add the Alias /foo/ /path/to/foo/ in virtualhost directive,but it has no effect. request of host1/foo/ will return 404. But if I add this to /etc/apache2/mods-available/alias.conf, it works. But the problem is host2 will also share this alias. Is there a way to make the alias work only for host1? B.T.W, I use apache2ctl -l, there's no mod_alias.c listed, weird.

Creating nodes porgramatically in Drupal 6

- by John

Hey, I have been searching for how to create nodes in Drupal 6. I found some entries here on stackoverflow, but the questions seemed to either be for older versions or the solutions did not work for me. Ok, so here is my current process for trying to create $node = new stdClass(); $node->title = "test title"; $node->body = "test body"; $node->type= "story"; $node->created = time(); $node->changed = $node->created; $node->status = 1; $node->promote = 1; $node->sticky = 0; $node->format = 1; $node->uid = 1; node_save( $node ); When I execute this code, the node is created, but when I got the administration page, it throws the following errors: warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. user warning: Duplicate entry '36' for key 1 query: INSERT INTO node_comment_statistics (nid, last_comment_timestamp, last_comment_name, last_comment_uid, comment_count) VALUES (36, 1269980590, NULL, 1, 0) in C:\wamp\www\steelylib\sites\all\modules\nodecomment\nodecomment.module on line 409. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. warning: Invalid argument supplied for foreach() in C:\wamp\www\steelylib\includes\menu.inc on line 258. I've looked at different tutorials, and all seem to follow the same process. I'm not sure what I am doing wrong. I am using Drupal 6.15. When I roll back the database (to right before I made the changes) the errors are gone. Any help is appreciated!

Linq to SQL Problem System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager

- by luckyluke

I have a really tricky thing going up here. My project has around 100 tables and they are all mapped by LINQ. Everything works fine in a dev and test environment. These enviroments are MS Win 2008 r2 servers with SQL 2008 sp1 databases. IIS and SQL are on a different machines. Now on production enviroment which is MS Win 2003 x64 web farm + geoclustered SQL 2008 IT DOES not work. All I get is the exception System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager3.TryCreateKeyFr>om Values(Object[] values, MultiKey& k) at System.Data.Linq.IdentityManager.StandardIdentityManager.IdentityCache2.Find(Object[] keyValues) at System.Data.Linq.ChangeProcessor.GetOtherItem(MetaAssociation assoc, Object instance) at System.Data.Linq.ChangeProcessor.BuildEdgeMaps() at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at ERS.IIMP.Services.ExposuresSrv.Update(Int32 ExpID, Int32 AssID) Services\ExposuresSrv.cs` My question is What the hell. They have precisely the same DBML, the DB has exactly THE SAME structure (when I get the DB from prod to TEST and mount it eveything works just great), the binaries on the WEB Server are the same. I seriously do not know what to do.... Did anyone found that Linq works on one env and does not on the second?? I mam really lost here. I really hope You can help me:)

This is not picked up during the sql schema generation. I also tried: mapping.Map(x = x.text, "text").Length(100000); Any ideas? Thanks. Christian

Should I be relying on WebTests for data validation?

- by Alexander Kahoun

I have a suite of web tests created for a web service. I use it for testing a particular input method that updates a SQL Database. The web service doesn't have a way to retrieve the data, that's not its purpose, only to update it. I have a validator that validates the response XML that the web service generates for each request. All that works fine. It was suggested by a teammate that I add data validation so that I check the database to see the data after the initial response validator runs and compare it with what was in the input request. We have a number of services and libraries that are separate from the web service I'm testing that I can use to get the data and compare it. The problem is that when I run the web test the data validation always fails even when the request succeeds. I've tried putting the thread to sleep between the response validation and the data validation but to no avail; It always gets the data from before the response validation. I can set a break point and visually see that the data has been updated in the DB, funny thing is when I step through it in debug with the breakpoint it does validate successfully. Before I get too much more into this issue I have to ask; Is this the purpose of web tests? Should I be able to validate data through service calls in this manner or am I asking too much of a web test and the response validation is as far as I should go?

How to limit traffic using multicast over localhost

- by Shane Holloway

I'm using multicast UDP over localhost to implement a loose collection of cooperative programs running on a single machine. The following code works well on Mac OSX, Windows and linux. The flaw is that the code will receive UDP packets outside of the localhost network as well. For example, sendSock.sendto(pkt, ('192.168.0.25', 1600)) is received by my test machine when sent from another box on my network. import platform, time, socket, select addr = ("239.255.2.9", 1600) sendSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 24) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_IF, socket.inet_aton("127.0.0.1")) recvSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True) if hasattr(socket, 'SO_REUSEPORT'): recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, True) recvSock.bind(("0.0.0.0", addr[1])) status = recvSock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, socket.inet_aton(addr[0]) + socket.inet_aton("127.0.0.1")); while 1: pkt = "Hello host: {1} time: {0}".format(time.ctime(), platform.node()) print "SEND to: {0} data: {1}".format(addr, pkt) r = sendSock.sendto(pkt, addr) while select.select([recvSock], [], [], 0)[0]: data, fromAddr = recvSock.recvfrom(1024) print "RECV from: {0} data: {1}".format(fromAddr, data) time.sleep(2) I've attempted to recvSock.bind(("127.0.0.1", addr[1])), but that prevents the socket from receiving any multicast traffic. Is there a proper way to configure recvSock to only accept multicast packets from the 127/24 network, or do I need to test the address of each received packet?

Oracle T4CPreparedStatement memory leaks?

- by Jay

A little background on the application that I am gonna talk about in the next few lines: XYZ is a data masking workbench eclipse RCP application: You give it a source table column, and a target table column, it would apply a trasformation (encryption/shuffling/etc) and copy the row data from source table to target table. Now, when I mask n tables at a time, n threads are launched by this app. Here is the issue: I have run into a production issue on first roll out of the above said app. Unfortunately, I don't have any logs to get to the root. However, I tried to run this app in test region and do a stress test. When I collected .hprof files and ran 'em through an analyzer (yourKit), I noticed that objects of oracle.jdbc.driver.T4CPreparedStatement was retaining heap. The analysis also tells me that one of my classes is holding a reference to this preparedstatement object and thereby, n threads have n such objects. T4CPreparedStatement seemed to have character arrays: lastBoundChars and bindChars each of size char[300000]. So, I researched a bit (google!), obtained ojdbc6.jar and tried decompiling T4CPreparedStatement. I see that T4CPreparedStatement extends OraclePreparedStatement, which dynamically manages array size of lastBoundChars and bindChars. So, my questions here are: Have you ever run into an issue like this? Do you know the significance of lastBoundChars / bindChars? I am new to profiling, so do you think I am not doing it correct? (I also ran the hprofs through MAT - and this was the main identified issue - so, I don't really think I could be wrong?) I have found something similar on the web here: http://forums.oracle.com/forums/thread.jspa?messageID=2860681 Appreciate your suggestions / advice.

Cisco ASA - VPN and Hairpinning....

- by Nordberg

Hi, We have 2 sites that will be linked by a IPSEC VPN between 2 Cisco ASAs: Site 1 8Mb ADSL Connection Cisco ASA 505 Site 2 2Mb SDSL Connection Cisco ASA 505 Basically, both sites need access to a service at the end of another IPSEC VPN, Site 3, which I plan to terminate at Site 2. This is due to the way the service is sold - it's billed per gateway. So if both Site 1 and Site 2 had their own VPN connection to Site 3, it would cost us twice as much... Anyway, my idea is to have all traffic from Site 1 destined for Site 3 to go via the VPN between Site 1 and Site 2. The end result being all traffic that hits Site 3 has come via Site 2. I understand this is known as hairpinning but I'm struggling to find a great deal of information on how this is setup. So, firstly, can anyone confirm that what I'm trying to achieve is possible and, secondly, can anyone point me in the direction of an example of such a configuration? Many Thanks.

Can I temporarily leave other roles active when converting a 2008 R2 server to a hyper-v host?

- by Eric

I currently have a Windows 2008 R2 box that I want to convert to a hyper-v host. Currently I have the following running on it: File Services, Web Server (IIS), and Sql Server 2008 R2 with a few different DBs. In the long term, I'd like to move all of those over to the VMs that will be created. However, in the short term I'd like to leave them running on the server. Are there any complications/problems with leaving them running on the hyper-v server for a day or two? How long will those services typically go down during the addition of the hyper-v role? Right now my plan is to back up everything, enable the hyper-v role, set up VMs, and migrate stuff off of the host. However, if there is a good probability that something may cease to function I might need to migrate everything over to a temporary host before doing the conversion.

How can I download django-1.2 and use it across multiple sites when the system default is 1.1?

- by meder

I'm on Debian Lenny and the latest backports django is 1.1.1 final. I don't want to use sid so I probably have to download django. I have my sites located at: /www/ and I plan on using mod_wsgi with Apache2 as a reverse proxy from nginx. Now that I downloaded pip and virtualenv through pip, can someone explain how I could get my /www/ sites which are yet to be made to all use django-1.2? Question 1.1: Where do you suggest I download django-1.2? I know you can store it anywhere but where would you store it? Question 1.2: After installing it how do you actually tie that django-1.2 instead of the system default django 1.2 to the reverse proxied Apache conf? I would prefer it if answers were more specific than vague and have examples of setups.
