• Facebook calling Google App Engine code using GET instead of POST

  - by Nick Gotch

  I've been developing a Facebook app using Google App Engine in Python and the pyfacebook bindings. For weeks everything worked fine but suddenly it stopped. At first I thought it was a code change so I rolled back the entire dev directory to a version I knew worked, but still it failed. It's possible a change I made to the application's settings caused the issue but, if so, I can't figure out what. I've figured out that the problem is that instead of calling the post(self) method of my Main class, Facebook is calling using a GET. Does anyone know why Facebook would use a GET method instead of a POST? It's an IFrame app. Thanks,

• IIS6 Metabase Compatiblity not installing correctly for Vista IIS7

  - by Mr Snuffle

  I've been bashing my head against this one for a few days, and haven't had any luck with it. I'm unable to get my VS2010 ASP.NET project to deploy to IIS. I receive the error "Unable to create the virtual directory. To access local IIS Web sites, you must install the following IIS Components IIS 6 Metabase and IIS 6 Configuration Compatibility ASP.NET In addition, you must run Visual Studio in the context of an Administrator Account" I've most certainly installed the metabase option, but it still shows up. I'm also not sure why it's telling me to install ASP.NET. Google is being entirely unhelpful, I was wondering if anyone here has any suggestions. I'm running Vista Ultimate 64Bit

• Using a filename with spaces with scp and chmod in bash.

  - by speciousfool

  Periodically, I like to put files in the /tmp directory of my webserver to share out. What is annoying is that I must set the permissions whenever I scp the files. Following the advice from another question I've written a script which copies the file over, sets the permissions and then prints the URL: #!/bin/bash scp "$1" SERVER:"/var/www/tmp/$1" ssh SERVER chmod 644 "/var/www/tmp/$1" echo "URL is: http://SERVER/tmp/$1" When I replace SERVER with my actual host, everything works as expected...until I execute the script with an argument including spaces. Although I suspect the solution might be to use $@ I've not yet figured out how to get a spaced filename to work.

• How to use genstrings across multiple directories?

  - by mystify

  I have an directory, which has a lot of subdirectories. those subdirs sometimes even have subdirs. there are source files inside. How could I use genstrings to go across all these dirs and subdirs? Let's say I cd to my root dir in Terminal, and then I would type this: genstrings -o en.lproj *.m How could I tell it now to look into all these directories? Or would I have to add a lot of relative paths comma separated? how?

• how does NTFS actually work with B-tree ?

  - by bakra

  To improve performance, NTFS directories use a special data management structure called a B-tree. "B-tree" concept here refers to a "tree of storage units" that hold the contents of an individual directory. What I don't understand is where on the disk is this tree stored? Its surely not created every-time we reboot...that would take lots of time. and since its a tree(dynamic Data structure) unlike arrays it will grow. so space needs to be allocated every-time it grows. so how is this "dynamic meta-data" stored ?

• git- how to troubleshoot "cannot find command"

  - by Frank Schwieterman

  I need help getting git extensions to run with msysgit. I have had bad luck with extensions git-tfs and git-fetchall, in both cases it is the same problem. The addon will require a file to be placed where git can find it (git-tfs.exe and git-fetchall.sh). I understand this to mean the files need to be in a directory that is in the 'PATH' environment variable. In both cases I get stuck at this point: $ git-diffall bash: git-diffall: command not found When I run echo %PATH% from a regular command shell, it shows my path variable includes the directories where git-diffall and git-tfs are. How can I debug this, or am I missing something? Is there a way within msysgit to verify the command search path is what I expect?

• DOS batch command to read some info from text file

  - by Ray

  Hello All, I am trying to read some info from a text file by using windows command line, and save it to a variable just like "set info =1234" Below is the content of the txt file, actually I just need the revision number, and the location of it is always the same line 5, and from column 11 to 15.

• How to add a Web Reference to a SSL web service?

  - by Matt W

  Hi, I have a web service in a C#/3.5 project which has been running fine. This is until I set the "SSL port" in IIS to 443 and set the "IIS - Directory Security - Secure Communications - Require secure channel (SSL)" option to true. Now, the web reference cannot be updated and I cannot add a new web reference to the web service in that site. When I try to view the service in a browse using just HTTP I get the "This page must be viewed over a secure channel" and when viewed with HTTPS on the front I get "This web page not available." Could someone tell me how to get a Web Reference added using Visual Studio to this secure web service, please? Thanks, Matt.

• Guice + Quartz + iBatis

  - by DroidIn.net

  I'm trying to wire together Guice (Java), Quartz scheduler and iBatis (iBaGuice) to do the following: Start command line utility-scanner using main() Periodically scan directory (provided as argument) for files containing formatted output (XML or YAML) When file is detected, parse and output result to the database The problems: I used this example to wire Guice and Quartz. However I'm missing some important details which I'm asking in the comments but the post is somewhat dated so I'm quoting it here also: It's not obvious how to set-up the scheduler. Where and how would I wire the Trigger (I can use Trigger#makeMinutelyTrigger)? I really have just one type of job I will be executing, I understand that details in the JobFactory#newJob are coming from the TriggerFiredBundle parameter but where/how do I wire that? And where/how do I create or wire concrete Job?

• Preventing Rails from opening production.log, when it is deployed with jruby-rack into tomcat.

  - by gregor

  I have to to deploy a Ruby on Rails application to an tomcat application server using jruby-rack. Due to security reasons my customer has the webapps directory mounted read only and he won't changed this. The problem that arises is, that the rails logger wants to open the WEB-INF/log/production.log in write mode. He writes nothing to this file because log4j and friends are configured and working, but rails complains that the file is not readable. Are there any suggestions from preventing rails from opening this file?

• Connecting two Windows XP with MSMQ

  - by NealWalters

  This question is a cross between a developer and a server setup question. I asked on Serverfault but no answer yet. As a developer, I need to setup a test to see how MSMQ works between two machines, and I'm unclear what to do. I will use C# or BizTalk to do the read/write to/from the queues. I have MSMQ installed on two Windows XP computers. Can I configure them to pass messages back and forth, or do I need an MSMQ server in the middle? If I need an MSMQ server, does the normal MSMQ with Win2003 able to act as that? And then, how do I connect my Windows XP to that Windows 2003 server? Is it a) On screen admin dialog in the MSMQ plug-in to MMC, b) a config file, c) Active Directory, d) something else? Thanks, Neal Walters

• Should I obscure primary key values?

  - by Scott

  I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?

• How do I set the Execute Permissions for an IIS6 website with Powershell using WMI?

  - by DarkwingDuck

  In inetmgr you can set the property I desire by going to Home Directory - Application Settings - Execute Permissions - and setting the drop down to 'Scripts Only'. I'm trying to replicate this behavior in Powershell. The Target OS is Windows Server 2003 running IIS6. Currently I have this simple code to get the site: $Site = get-wmiobject -Namespace root\MicrosoftIISv2 -query ('select * from IISWebServerSetting where ServerComment="mySite"') There are lots of properties it might be but nothing really leaps out. I've tried changing the setting in inetmgr and dumping the properties out before and after, but I see no differences (it could be a child property though). Any ideas? Thanks in advance.

• Ruby on Rails ActiveRecord: eager loading issue with foreign and primary key

  - by Krishnaswamy Subramanian

  The eager loading on Ruby on Rails is not working properly for the following scenario. First we had a model called marks which has the following fields id, student, subject, mark the student is a string column which has the active directory login value, later on for reporting functionality we introduce another table called user which has the following fields id, ad_name, full_name Now on the Mark model, we have added the belongs to class belongs_to :student_details, :class_name = "User", :foreign_key = "student", :primary_key = "ad_name" and when loading using the ActiveRecord's find method we are passing in the include conditon for eager loading Marks.find(:all, :include = :reserved_user) but when the find is executed, for each and every mark a student select query executed. Is this a known bug in ROR? or am i missing something?

• How to use NUnit GUI with a C#/ASP.NET website?

  - by Amber Shah

  I have a C#/ASP.NET website that has some code (*.cs) files in the App_Code directory. I would like to test them using NUnit. I have written a test file with the proper [TestFixture] and [Test] annotations and have put it here: App_Code/Test/TestClassName.cs. I load up the NUnit GUI to run it but it wants me to select a .exe or .dll file. There is none in the bin folder of my project. My project does successfully run and is built and everything, but still no exe or dll file. How can I get the NUnit Gui to just run the test in that class?

• Hide horizontal scrollbar in IE 7 and below

  - by Bradley Bell

  Hi all. Basically, I'm having trouble removing the horizontal scrollbar in Internet Explorer 7 and Below. I've tried the code below and It seems to work fine in every browser except IE. overflow-x: hidden; The even bigger problem is that, even though the scrollbar isn't even removed, it seems to completely screw the layout.. It somehow hides the majority of the page content in boxes 2 and 3? It also.. adds a second vertical scrollbar which moves relatively/absolute positioned items down?! I did contemplate just leaving the scrollbar in IE via a specified stylesheet, but even that seems to be messing with the page? The website is on a test directory here.. I'll post the stylesheet in a comment below. Any suggestions? Thanks in advance, hope you can help! Bradley

• Merging two folders using git

  - by vrish88

  I'm working on a project with some people who have never used git before. Not knowing the capabilities of git, they created two version of the project: development and production. These two versions are both present in the current environment. To complicate things further, this other user created these folders in addition to the old development folder. So the project directory looks like this /root /proj (old dev folder with my own code in it) /dev_proj (new folder which I would like to merge /prod with) /prod_proj (production code) So what I'd like to do is merge the work that I've done in /proj with the work in the /dev_proj. Is there a way to do this with git? I've thought about creating a branch, copying all the files from /proj to /dev_proj and merging that branch with master. Would this work? Thanks and if I could clarify something let me know.

• python object AttributeError: type object 'Track' has no attribute 'title'

  - by ccwhite1

  I apologize if this is a noob question, but I can't seem to figure this one out. I have defined an object that defines a music track (NOTE: originally had the just ATTRIBUTE vs self.ATTRIBUTE. I edited those values in to help remove confusion. They had no affect on the problem) class Track(object): def __init__(self, title, artist, album, source, dest): """ Model of the Track Object Contains the followign attributes: 'Title', 'Artist', 'Album', 'Source', 'Dest' """ self.atrTitle = title self.atrArtist = artist self.atrAlbum = album self.atrSource = source self.atrDest = dest I use ObjectListView to create a list of tracks in a specific directory ....other code.... self.aTrack = [Track(sTitle,sArtist,sAlbum,sSource, sDestDir)] self.TrackOlv.AddObjects(self.aTrack) ....other code.... Now I want to iterate the list and print out a single value of each item list = self.TrackOlv.GetObjects() for item in list: print item.atrTitle This fails with the error AttributeError: type object 'Track' has no attribute 'atrTitle' What really confuses me is if I highlight a single item in the Object List View display and use the following code, it will correctly print out the single value for the highlighted item list = self.TrackOlv.GetSelectedObject() print list.atrTitle

• Creating an installer with WPF forms, packaged files and custom setup actions in C#

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• How to deal with symbolic links when going between Linux and Windows?

  - by Jesse Beder

  I have a django project that runs on a Linux server, and I've been working on it both on Linux and OS X. I've noticed that some of the pages are a bit off, to put it politely, in Internet Explorer, and so I checked out the subversion repository on Windows and tried to run a local server. My media directory has symbolic links to all of the media from each different app, and obviously Windows doesn't know what to do with them. I could simply hard-copy or link everything manually in Windows, but then I wouldn't be able to check that in (since the site runs on a Linux server), so it'd be a pain in the neck. What is typically done in this case?
