• First Fluent NHibernate Project

  - by Andy

  I'm trying to follow the "Your first project" tutorial at http://wiki.fluentnhibernate.org/Getting_started and have hit a roadblock. When I try to run the console application, I'm getting this error: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. I have created a SQLite database "firstProject.db" and referenced the full path to the file in the call to: return Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile)) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); so I don't know what I'm doing wrong. What/where is this "PotentialReasons" collection? Thank you for the help. Andy

• how to use font-faces in css file within spring 3

  - by miguel.angel

  I'm trying to use font-faces inside a style.css file. I have put my style font .ttf file into resources with Spring 3. When use font-faces i need to put the path to the .ttf file like this: @font-face{ font-family: NosiferCaps-Regular; src: url('../fonts/1942/1942.ttf'); } .myClass{ font:39px/1.2 NosiferCaps-Regular, verdana ; text-shadow:2px 2px 9px gray; } So, how do I refer to "src: url('../fonts/1942/1942.ttf')" inside a style.css file with Spring?

• Operant conditioning algorithm?

  - by Ken

  What's the best way to implement real time operant conditioning (supervised reward/punishment-based learning) for an agent? Should I use a neural network (and what type)? Or something else? I want the agent to be able to be trained to follow commands like a dog. The commands would be in the form of gestures on a touchscreen. I want the agent to be able to be trained to follow a path (in continuous 2D space), make behavioral changes on command (modeled by FSM state transitions), and perform sequences of actions. The agent would be in a simulated physical environment.

• Autotest notifications on Ubuntu virtual environment

  - by Luciano

  I am having trouble getting Rails autotest notifications to work on the Engine Yard Vagrant environment. On the Mac, I normally get the notifications via Growl. However, on the virtual environment (which runs Ubuntu) that doesn't work. I tried running Linux notification setups such as libnotify+autotest-notification, but I get the following error: libnotify-Message: Unable to get session bus: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_call: assertion `DBUS_IS_G_PROXY (proxy)' failed Another path would be to have Growl receive the notifications remotely, but I don't even know where to begin with that... Any suggestions?

• RewriteRule being greedy

  - by lardlad

  I have been looking for an answer for a few hours now, so sorry if this was asked a ton of times, I missed it. I basically want to make a rewrite to ignore the first directory. That first dir in the path will be different so I thought I could use a regex. But my regex is matching all the way to the file name: RewriteRule ^([a-z]+)?/(.+)$ $2 [L] this works if I am one level deep: http://test.domain.com/one/index.php I get the actual index page of the root. Which is what I want. but if I were to go deeper: http://test.domain.com/one/two/index.php I get a message saying /index.php was not found. So it seems my regex is not stopping after the last [a-z]. I appreciate any help. This is Apache2 if that matters at all.

• How to set the bounce address using System.Net.Mail?

  - by Anthony

  I'm trying to implement the Variable envelope return path (VERP) method to manage email addresses (ie when an email I send bounces back I want it to be sent to a specific email address so that I can update my database to avoid sending emails to that email address in the future). According to this article it is possible to specify the email address a bounce email is sent to. How do you do this in .Net? For example say I ([email protected]) want to send an email to you ([email protected]). If [email protected] doesn't exist anymore I want yourserver to send the bounce email to [email protected]). This way when I receive this bounced email I know that [email protected] is not a valid email address anymore and I can update my database accordingly. In this example, the bounce address would be: [email protected] How do you specify it using System.Net.Mail?

• Given a Member Access lambda expression, convert it to a specific string representation with full ac

  - by Nathan

  Given an Expression<Func<T, object>> (e.g. x = x.Prop1.SubProp), I want to create a string "Prop1.SubProp" for as deep as necessary. In the case of a single access (e.g. x = x.Prop1), I can easily do this with: MemberExpression body = (expression.Body.NodeType == ExpressionType.Convert) ? (MemberExpression)((UnaryExpression)expression.Body).Operand : (MemberExpression)expression.Body; return body.Member.Name; However, if there is deeper nesting, e.g. x = x.Prop1.SubProp1, this only gets the most deeply nested name, e.g. "SubProp1" instead of "Prop1.SubProp1" Is there anyway to access the full property path of a lambda expression?

• ASP.NET Build Images Links Dynamically

  - by coson

  Good Day, I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code): DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "http://external_server/path/to/file1.jpg" If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML. Any thoughts? TIA, coson

• simple EJB jar deployed in jboss with its own log4j configuration

  - by user309281

  Hi All I have a simple EJB jar with a stateless session bean, deployed in JBOSS AS 4.2.2, unde r/server/default/deploy. The bean is registered under JNDI tree as viewed from jboss jmx console and I am able to access it through a remote java client outside JBOSS. Inside EJB jar, I have added some logging to be written to a separate log file, using apache log4j jar and log4j.xml. But I am not able to view any of the logs. Also I do not wish to use jboss-log4j.xml, since there will be many other EJBs to be deployed and wish to have separate log4j for each EJB application. Here is my one of the EJB-jar contents: EJB_DS.jar: log4j.xml classes apache log4j jar is added to /server/default/lib path. Kindly highlight if i have missed any points for enabling log4j configuration With Regards, Krishna

• Determine calling executable in Python

  - by Brian Rosner

  I am trying to find the best way of re-invoking a Python script within itself. Currently it is working like http://github.com/benoitc/gunicorn/blob/master/gunicorn/arbiter.py#L285. The START_CTX is created at http://github.com/benoitc/gunicorn/blob/master/gunicorn/arbiter.py#L82-86. The code is relying on sys.argv[0] as the "caller". However, this fails in cases where it is invoked with: python script.py ... This case does work: python ./script.py ... because the code uses os.chdir before running os.execlp. I did notice os.environ["_"], but I am not sure how reliable that would be. Another possible case is to check if sys.argv[0] is not on PATH and is not executable and use sys.executable when calling os.execlp. Any thoughts on a better approach solving this issue?

• How do I get Cabal to bypass my Windows proxy settings?

  - by Brent.Longborough

  When retrieving packages with Cabal, I frequently get errors with this message: user error (Codec.Compression.Zlib: premature end of compressed stream) It looks like Cabal is using my Windows Networking proxy settings (for Privoxy). From digging around Google, Cabal or its libraries appear to have (had) a problem in this area. Possible solutions I can see are: Turn off proxying while using Cabal (not very keen on this one); or Get a patch and start hacking. I'm hesitant to go down this path, as I'm a complete Haskell noob and I'm not yet comfortable with Darcs; or Give it the magic "can I haz no proxy" parameter. Hence the question.

• Search for a pattern in a list of strings - Python

  - by Holtz

  I have a list of strings containing filenames such as, file_names = ['filei.txt','filej.txt','filek.txt','file2i.txt','file2j.txt','file2k.txt','file3i.txt','file3j.txt','file3k.txt'] I then remove the .txt extension using: extension = os.path.commonprefix([n[::-1] for n in file_names])[::-1] file_names_strip = [n[:-len(extension)] for n in file_names] And then return the last character of each string in the list file_names_strip: h = [n[-1:] for n in file_names_strip] Which gives h = ['i', 'j', 'k', 'i', 'j', 'k', 'i', 'j', 'k'] How can i test for a pattern of strings in h? So if i,j,k occur sequentially it would return True and False if not. I need to know this because not all file names are formatted like they are in file_names. So: test_ijk_pattern(h) = True no_pattern = ['1','2','3','1','2','3','1','2','3'] test_ijk_pattern(no_pattern) = False

• I can't use dashes in XPATH on iphone using libxml2

  - by user249488

  I'm trying to parse HTML data using KissXML for iphone. I've noticed that I can't have dashes in the id() tag, otherwise it won't evaluate. For example, if I'm trying to get the element at I would do id("foo") However, if I try to get at element , and I try id("foo-bar") the libxml2 XPATH engine doesn't seem to return anything. It works using the XPATH check for firefox, though. Anyone run into this issue and know of a reason why it's happening or have a workaround (besides using the absolute XPATH path?)

• Can you open an SPSite object while being within a different site collection?

  - by Chris Stewart

  I'm working on creating a common navigation experience across two site collections in MOSS 2007. I've looked around for various solutions and haven't found anything that fits. Our navigation is dynamic and driven by a number of factors, including audience targeting. Most of what I've found relates to having static XML and that just won't work for our requirements. What I'm down to at the moment is just getting a navigation item from site collection A while in the context of site collection B. Are there reasons I shouldn't be able to just open a navigation item from site collection A and gets its audience? Certainly there could be permissions problems on my end, or code related issues, or things that are in my control. What I'm wondering is if there's something inherent to SharePoint that would not allow this. Something I don't have control over which would force me to travel a different path.

• Rails testing authlogic

  - by pepernik

  I just started using tests. I try to test the login like this require 'test_helper' class UserFlowsTest < ActionController::IntegrationTest fixtures :all # Replace this with your real tests. test "login and browse" do https! get "/users/new" assert_response :success post "/user_sessions", :email => '[email protected]', :password => 'aaaa' follow_redirect! assert_equal root_path, path end end I use authlogic gem in my rails app. What is wrong with this test? It breaks at 'follow_redirect!' saying it is not a redirection but login through a browser works. Thx!

• [Zend Framework] Is there any way to use more than 1 bootstrap class?

  - by rasouza

  It should sound workaround or something like, but I'll tell you what: I chose to have a separated "project" with every library I could use. It's like a global library which I included Zend library, Doctrine ORM, JQuery, Blueprint CSS, etc. Then I set the include path. Nothing wrong. The problem is: I'd like to have also a global bootstrap class inside the library folder and an individual bootstrap class on each project I create for individual use. I don't know how to set more than 1 bootstrap class. Is it possible?

• How do you set the height of an object to Auto when Animating in WPF?

  - by discwiz

  Tring to animate the expanding and contracting of a WPF Expander in .Net 4.0 using PowerEase. The animation works except I have to hardcode the height or bind to the height of an object in the expander which does not give the desired height. I need to set the "To" of the expander to Auto in animation. <Storyboard x:Name="myStoryboardContract" x:Key="myStoryboardContract"> <DoubleAnimation From="{Binding ElementName=MapsExpander, Path=ActualHeight}" To="30" Duration="00:00:3" Storyboard.TargetName="MapsExpander" Storyboard.TargetProperty="Height"> <DoubleAnimation.EasingFunction> <PowerEase Power="20" EasingMode="EaseOut"/> </DoubleAnimation.EasingFunction> </DoubleAnimation> </Storyboard> </Expander.Resources> <TextBlock x:Name="Text1" Text="Hi this is nothing but junk."/> </Expander>

• I would like to useJava 7's FileVisitor to walk up a tree

  - by John Ormerod

  I have looked and searched for some guidance on how to start at a low point in a path and walk up (or 'back'), until I find a folder with the name I am searching for. The FileVisitor class looks like it ought to be able to help me, but it only seems to work from head to toe. Is there something that someone could point me to? Thanks, John {edited: I seem to be discouraged from saying thanks to the two people who replied in a comment. So thanks! I had a 'duh!' moment when I saw the simple approach. And the article looks useful to someone starting to use FileVisitor. Put them together, and I could go up and then down, if I needed to. John]

• Sharing [config] data across modules,functions

  - by williamstw

  I have some configuration data in a config file that I read off disk when the app starts. I need to make that configuration data available to other functions/modules in the application. I started down the path of looking into ets/mnesia to store the data on startup to make it shared among all processes, but then my inner voice cautioned me that there must be a more functional, erlang-y way to do this. The only alternate approach I've come up with so far is setting up a module that has an actor loop that reads the data on startup and responds to messages like {Key, From} and responds by From ! {ok,Value}. Then, I gave up and decided to ask... Thanks, --tim

• How to check value of stored procedure output parameter

  - by Anna T

  I have a stored procedure that: A. inserts some rows into a "table variable" based on some joins B. selects all values from column x from that table into a string with comma separated values C. selects all from the "table variable" If I execute the procedure like this: EXEC CatalogGetFilmDetails2 2,111111; a table is returned as instructed per step C above. How can I execute it so that also the output parameter value is displayed? (see point B above). I need to check if it's calculated properly. And since the second parameter is of output type, meaning it's calculated inside the procedure, why is it mandatory to specify a value for it when executing the procedure? I normally use a random value for it, it anyway doesn't matter/impact the result. On the other hand if I try to execute it without the output parameter, it returns an error) Thank you very much! This is how the procedure starts: CREATE PROCEDURE CatalogGetFilmDetails2 (@FilmID int, @CommaSepString VARCHAR(50) OUTPUT) AS And this is how @CommaSepString is calculated: SELECT @CommaSepString = STUFF((SELECT ', ' + Categ FROM @Filme1 FOR XML PATH('')), 1,1,'')

• Changing the HTML of CKEditor form elements (in the dialog window)

  - by Kenny Meyers

  I'm trying to modify the HTML of the dialog boxes in CKEditor. The HTML inside each of those boxes is an absolute nightmare, and even worse, the source code is compressed and it's unclear what the path of execution is. I want to take something like this: <div class="cke_dialog_ui_select" id="44_uiElement" role="presentation"><label style="" for="42_select" id="43_label" class="cke_dialog_ui_labeled_label">Link Type</label><div role="presentation" class="cke_dialog_ui_labeled_content"><select aria-labelledby="43_label" class="cke_dialog_ui_input_select" id="42_select"><option value="url"> URL</option><option value="anchor"> Link to anchor in the text</option><option value="email"> E-mail</option></select></div></div> and turn it into something more legible and easier to style, removing one of the divs. These are for the Image and Anchor dialog boxes (Modal dialogues) respectively. Thanks for your help.

• Selenium / FlashSelenium calling the wrong methods?

  - by bug-a-lot

  Seems like sometimes when Selenium should call a certain method, it instead calls another, as pointed out by the following log: 14:57:18.328 INFO - Command request: getEval[this.browserbot.findElement("someElement").doFlexClick('someIdOfAButton','');, ] on session 21708b0a4a154ebc96c9720c14578e74 14:57:18.343 INFO - Got result: OK,Error: Cannot type text into someIdOfAButton on session 21708b0a4a154ebc96c9720c14578e74 I've tried both Selenium server 1.0.3 and the 2.0 alpha 7 versions, they both display this behaviour. FlashSelenium is involved so I'm not sure where along the way lies the bug. Furthermore it's hard to reproduce as it doesn't happen only for some methods, and doesn't always happen. I've tried searching for issues similar to these but couldn't find any remotely similar... Anyone experienced the same behavior? And if so, is there a fix for it? Edit: I doubt FlashSelenium is at fault for this, as the log tells that the command arrives correctly at the server... But I can't seem to be able to follow the path of execution from the moment the Selenium server gets the command and passes over to the browser, to the moment where it gets the response.

• generic function for extracting values from an array with one particular key in PHP

  - by Sabya

  Is it possible in PHP to extract values from an array with a particular key path and return an array of those values? I'll explain with an example: $user = array ( array( id => 1, email =>'[email protected]', project => array ('project_id' => 222, 'project_name' => 'design') ), array( id => 2, email =>'[email protected]', project => array ('project_id' => 333, 'project_name' => 'design') ) ); /** I have to write a function something like: */ $projectIds = extractValuesWithKey($user, array('project', 'project_id')); print_r($projectIds); Output: Array( [0] => 222, [1] => 333 )
