• Most inappropriate function or variable names you have encountered?

  - by Andrioid

  I was reading through my daily doze of RSS when I noticed a link to the python compiler documentation where class names like assList, assName and assTuple exist. While starting names with 'ass' is perfectly acceptable to me, it just sparked this idea that there probably exist much better examples of this. Have you personally used or otherwise encountered any inappropriate function or variable names? Personally I have used 'crap' and 'moo' for temporary purposes, forgot them and at a later point they came too integrated for me to bother with fixing them.

• AES and CBC in PHP

  - by Kane

  I am trying to encrypt a string in php using AES-128 and CBC, but when I call mcrypt_generic_init() it returns false. $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '',MCRYPT_MODE_CBC, ''); $iv_size = mcrypt_enc_get_iv_size($cipher); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $res = mcrypt_generic_init($cipher, 'aaaa', $iv); //'aaaa' is a test key Can someone tell me why is returning 0/false? I read the php documentation and seems correct (http://us.php.net/manual/en/mcrypt.examples.php)

• How to diff just the source files?

  - by Kimvais

  I have two almost similar source code trees, but do not have access to the source code repository so I am stuck with release packages that contain also test reports, documentation, binaries etc. the diff command only support --exclude, but I would like to do something like diff -wbur --include='*.c,*.h' tree1 tree2 I know that this question is somewhat related, but does not really address my issue. Bonus points for ignoring change blocks that are completely in C comments :)

• Cocoa : How do I catch drag operations initiated from an IKBrowserView?

  - by bucketmouse

  So I've got an IKBrowserView all wired up and happily dragging my custom datatype (provided lazily via PasteboardItem) from one window to another, but now I'm interested in detecting when the user drops some data onto the trashcan. Cocoa's documentation says to check the return type of the drag operation itself, but how exactly do I do this with an IKBrowserView? Once I call imageBrowser:writeItemsAtIndexes:toPasteboard: I don't seem to get any notifications other than the request for the pasteboard contents, which doesn't provide a pointer to the drag operation that invoked it.

  - by panofish

  I want to build perl apps with a gui that: A: are windows compatible (no cygwin or the like) B: utilize a nice GUI builder C: is easily distributed (minimizing additional components that must be installed) D: has good documentation and tutorials for building and using the GUI E: is still be developed (has a future) and appears to be the future of perl GUIs Maybe someone could provide a table something like the following for the alternatives (wxperl, perlqt, tk gtk2...etc)?: tool1 = AB tool2 = CE tool3 = ACD ...

• DataGridView live display of datatable using virtual mode

  - by Chris

  I have a DataGridView that will display records (log entries) from a database. The amount of records that can exist at a time is very large. I would like to use the virtual mode feature of the DataGridView to display a page of data, and to minimize the amount of data that has to be transferred across a network at a given time. Polling for data is out of the question. There will be several clients running at a time, all of which are on the same network and viewing the records. If they all poll for data, the network will run very slowly. The data is read-only to the user; they won't be able to edit any of it, just view it. I need to know when updates occur in the database, and I need to update the screen with those updates accordingly using virtual mode. If a page of data a user is viewing contains data that has change, he/she will see those updates on that page. If updates were made to data in the database, but not in the data the user is viewing, then not much really changes on the user screen (Maybe just the scroll bar if records were added or removed). My current approach is using SQL server change tracking with the sync framework. Each client has a local SQL Server CE instance and database file that is kept in sync with the main database server. I use the information from the synchronization event to see if any changes were made to the main database and were sync'ed to the client. I need to use the DataGridView virtual mode here because I can't have thousands of records loaded into the DataGridView at once, otherwise memory usage goes through the roof. The main challenge right now is knowing how to use virtual mode to provide a seamless experience to the user by allowing them to scroll up and down through the records, and also have records update on the fly without interfering with the user inappropriately. Has anybody dealt with this issue before, and if so, where I can see how they did it? I've gone through some of the MSDN documentation and examples on virtual mode. So far, I haven't found documentation and/or examples on their site that explains how to do what I am trying to accomplish.

• Differentiate gtk.Entry icons

  - by Ubersoldat

  I'm adding two icons to a gtk.Entry in PyGTK. The icons signals are handled by the following method def entry_icon_event(self, widget, position, event) I'm trying to differentiate between the two of them: <enum GTK_ENTRY_ICON_PRIMARY of type GtkEntryIconPosition> <enum GTK_ENTRY_ICON_SECONDARY of type GtkEntryIconPosition> How can I do this? I've been digging through the documentation of PyGTK but there's no object GtkEntryIconPosition nor any definition for this enums. Thanks

• Working with Multiple Layers - KineticJS

  - by Bruno Sampaio

  I'm using KineticJS 4.0.5 and I'm currently trying to draw the contents of several layers but only the last one added to stage is drawn... If I understood the documentation correctly this should be possible, otherwise why would we need a layer? I have three different layers: a background layer with just a Kinectic.Rect object; a elements layer with several types of shapes; and a top layer with elements I want to be always on top of everything. I populate those layers inside a draw function I have inside a object I created, this object also has a shape attribute which refers to the background and a contents attribute with the elements to add to the elements layer. My code for the draw function is the following: this.draw = function() { var stage = E.game.stage, layers = E.game.layers; stage.clear(); // Add Background this.shape.setSize(stage.getWidth(), stage.getHeight()); layers.background.add(this.shape); // Iterate over contents for(var i = 0; i < this.contents.length; i++) { layers.elements.add(this.contents[i].shape); } // Draw Everything stage.add(layers.background); stage.add(layers.elements); stage.add(layers.top); // This one is currently empty stage.draw(); } After running this function, only layers.top is drawn in the canvas, and if I comment the line where it is added only layers.elements is drawn. However the stage has 3 childrens (I checked it with inspect element on chrome) and in the documentation it says the draw function draws all layers... Am I doing something wrong here? Or it isn't possible? And if it's not possible why would I need a layer and a stage? Wouldn't one be enough? Thank you in advance. Edit: I was able to solve the problem, I was applying a white background color with css to the canvas element and since each layer creates a new canvas element above the others I could only see the contents for the top most layer (in this case just white). However, I still have a problem related with multiple layers that I didn't have before with just one layer. When I use the clear function on the stage it should clear the layers right? But instead the layers remain exactly the same, even if I try to call clear on each individual layer they won't change... I'm also using the stage draw function after clearing them but still no changes at all... The only solution I found until now was by removing the layer from the stage and adding it again :s Is there a better way to reset the layers contents? Thank you again and sorry for the confusion with the first question.

• R Package for Bayesian Belief Networks

  - by user187395

  Is anyone aware of an R package for Bayesian Belief Networks (BBN) that can handle latent (hidden) nodes? I am referring to process learning the structure and the parameters of the model. Based on the documentation, the "bnlearn" package does not provide for such capability. In addition, is anyone aware of R packages that allow for making inferences and sensitivity analysis for BBN? Thank you in advance.

• How can I configure apigee to fail stale if the backend is unavialble?

  - by Anurag Kapur

  We have an API proxy configured with cache ttl of 2mins. Is it possible to configure apigee to serve stale cached content if the backend goes down so that our end users don't see errors? We would rather have our end users get copies of stale cached content (even after the configured ttl of 2mins expires) instead of errors when the backend goes down. Would appreciate if someone could point me to the relevant documentation if this is possible.

• FlexBuilder debugger: what can the "expressions" tab be used for?

  - by David Wolever

  As the title suggests, is there any documentation on the FlexBuilder "expressions" tab, and what expressions it can accept? As far as I can tell, it can show the value of variables, but that's it: comparisons, function and method calls all fail: Edit: this is specific to FB3 — Flex Builder. Apparently FB4 — Flash Builder — is slightly less incompetent.

• Add newlines to a text resource in Android?

  - by shmuelp

  I have a custom Dialog that contains only a TextView to display some text in my application. The documentation lists that only the b, i, u, tt, big, small, sup, sub, and strike tags are supported. I really need to add some newlines for readability. Do I need to change to a more complicated layout, or is there some way to encode newlines in the resource? I tried adding br tags, but that did not help.

• Why are there magic attributes exposed in the Servlet spec?

  - by Brabster

  It's always seemed a little at odds with the principles of Java that the Java Servlet Spec (2.5 version here) includes a set of magic attributes containing info about included resources, namely: javax.servlet.include.request_uri javax.servlet.include.context_path javax.servlet.include.servlet_path javax.servlet.include.path_info javax.servlet.include.query_string It's not even specifically pointed out in the API documentation, only in the spec where it is a must for correct implementation. This approach feels very wrong, an exposed implementation detail that clients will use and depend on. Why is this information exposed in this way?

• Library to write javascript code

  - by Melursus

  Is there a c# library that can help to write and indent Javascript code. It's because I'm writing some c# code that generated some Javascript code. Something like this : js += "<script type=\"text/javascript\">\n"; js += " function()...\n"; And I find that generated a lot of ugly code. So, I thought that maybe a existing library can help me doing that ?

• how to start with a voip/public announcement project?

  - by Metiu

  The main requirements are: open source solution on Linux support P2P VoIP calls support presence support multicast VoIP announcements (and maybe some way of setting up such a "conference") preferably serverless (maybe the network can get split and I'd need to keep the functionality for all clients that still see each other) I tried looking at telepathy, in particular telepathy-salut, but it seems to be quite a new technology, so it lacks clear/good documentation and/or working examples. I'm also evaluating SIP (e.g. SofiaSIP), but it's working only if connected to a server.

• Where does User.Identity data come from?

  - by niaher

  For example: if I am retrieving User.Identity.Name, does it come from .ASPXAUTH cookie or is retrieved from the database using my membership provider? Are any database requests made when I access User.Identity? Thanks. EDIT: Right now I am pretty sure it comes from an authentication ticket cookie, but can't find any official documentation to confirm this. Anyone?

• How to access Virtual machine using powershell script

  - by Sheetal

  I want to access the virtual machine using powershell script. For that I used below script, Enter-PSSession -computername sheetal-VDD -credential compose04.com\abc.xyz1 where, sheetal-VDD is hostname of virtual machine compose04.com is the domain name of virtual machine and abc.xyz1 is the username of virtual machine After entering above command , it asks for password. When the password is entered I get below error, Enter-PSSession : Connecting to remote server failed with the following error message : WinRM cannot process the reques t. The following error occured while using Kerberos authentication: There are currently no logon servers available to s ervice the logon request. Possible causes are: -The user name or password specified are invalid. -Kerberos is used when no authentication method and no user name are specified. -Kerberos accepts domain user names, but not local user names. -The Service Principal Name (SPN) for the remote computer name and port does not exist. -The client and remote computers are in different domains and there is no trust between the two domains. After checking for the above issues, try the following: -Check the Event Viewer for events related to authentication. -Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or us e HTTPS transport. Note that computers in the TrustedHosts list might not be authenticated. -For more information about WinRM configuration, run the following command: winrm help config.
