• Are there any Python reference counting/garbage collection gotchas when dealing with C code?

  - by Jason Baker

  Just for the sheer heck of it, I've decided to create a Scheme binding to libpython so you can embed Python in Scheme programs. I'm already able to call into Python's C API, but I haven't really thought about memory management. The way mzscheme's FFI works is that I can call a function, and if that function returns a pointer to a PyObject, then I can have it automatically increment the reference count. Then, I can register a finalizer that will decrement the reference count when the Scheme object gets garbage collected. I've looked at the documentation for reference counting, and don't see any problems with this at first glance (although it may be sub-optimal in some cases). Are there any gotchas I'm missing? Also, I'm having trouble making heads or tails of the cyclic garbage collector documentation. What things will I need to bear in mind here? In particular, how do I make Python aware that I have a reference to something so it doesn't collect it while I'm still using it?

• Partial Git deployment strategy?

  - by MatW

  I need to setup a Kohana dev environment that allows me to make full use of shared module / system classes across separate applications. Each application typically belonging to a different client. I use Git for source control, but am struggling to come up with a clean deployment method that will allow me to pull only those parts of the dev environment specific to a client / app down into that client's production environment (assuming that the client's production environment will have Git installed). Dev enviroment: - kohana - applications - clientapp1 - clientapp2 - modules - public_html - clientapp1 - clientapp2 - system - 3.0.1 - 3.0.5 Client 1's production environment: - / - applications - clientapp1 - modules - public_html - client_app1 - system - 3.0.5 Naturally, I want to have total control over each client "sub repo" as if it were an independent repo (in terms of gitignore, etc). I have seen topics that cover Git's sparse checkout feature, but it seems like it may cause a few problems down the line from a maintenance point of view, and I don't like the idea of the entire repo's metadata existing in client's production environment repo. As you can probably tell, I'm not exactly a Git poweruser, so any suggestions / wisdom are very welcome!

• Authentication Error in C# Send Mail App

  - by doc

  I'm developing a simple send mail app in C#, using my CMail Server: MailMessage mail = new MailMessage("[email protected]", "[email protected]"); mail.Subject = "Sub"; mail.Body = "Hi!"; SmtpClient smtp = new SmtpClient("MyServer"); System.Net.NetworkCredential cred = new System.Net.NetworkCredential("user", "pass"); smtp.UseDefaultCredentials = false; smtp.Credentials = cred; smtp.Send(mail); Obviously i ommited my account information, so, this code throws me an Authentication Exception for some reason. I first thought that the code was wrong, so i change the info to my gmail account and everything goes fine, with the only SMTP server that i having trouble is with the CMail. Is there a problem with .NET and CMail's SMTP ? Thanks for the help and comments!

• Unable to connect to sql database only from asp

  - by Brian

  In a VB6 program: Dim conn As Object Set conn = CreateObject("ADODB.Connection") conn.Open "DRIVER={SQL Server}; Server=(local)\aaa; Database=bbb; UID=ccc; PWD=ddd" In an ASP program: Sub ProcessSqlServer(conn) Set conn = Server.CreateObject("ADODB.Connection") conn.Open "DRIVER={SQL Server}; Server=(local)\aaa; Database=bbb; UID=ccc; PWD=ddd" The VB6 program works, the ASP program does not (see error below). I tried checking the event log for errors, but found nothing. Or more precisely, I did find local an activation permission error, but this was fixed once I added local launch/activation permission for Network Service to the Machine Debug Manager via the component services tool. Error: Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC SQL Server Driver]Timeout expired

• Hierarchical data table for JSF2 and RichFaces

  - by Iravanchi

  I'm using RichFaces on my JSF2 application, and I need a way to have something like a tree-column or tree-table. As far as I know, there's no support for such thing in RichFaces. Something's mentioned for RichFaces 4.0, but the priority of this in their plan isn't promising at all, and I don't think that it's going to be included in 4.0. I know there's a tree table available in IceFaces, but I'd rather not add another library to avoid conflicts and learning curve and ... So, I'm looking for the simplest way that I can achieve the same results with minimum efforts, maybe using sub-tables in RichFaces? Any ideas would be appreciated.

• Optimal way to generate list of PHP object properties with delimiter character, implode()?

  - by Kris

  I am trying to find out if there is a more optimal way for creating a list of an object's sub object's properties. (Apologies for the crude wording, I am not really much of an OO expert) I have an object "event" that has a collection of "artists", each artist having an "artist_name". On my HTML output, I want a plain list of artist names delimited by a comma. PHP's implode() seems to be the best way to create a comma delimited list of values. I am currently iterating through the object and push values in a temporary array "artistlist" so I can use implode(). That is the shortest I could come up with. Is there a way to do this more elegant? $artistlist = array(); foreach ($event->artists as $artist) { $artistlist[] = $artist->artist_name; } echo implode(', ', $artistlist);

• Combining a web application with another (larger).

  - by Kevin Brown

  I'm writing a web app, initially meant to be stand-alone--it's essentially a survey with user-management/authentication built on Codeigniter. The company I'm doing this for wants to merge it with their main system so that it acts like a feature, or a sub-app of their website. What is the best thing for me to do? I think I could do one of two things: Finish my application, as I had planned to initially, and let them handle the merging.It would probably save me a headache. Stop where I am in development, and migrate my authentication system to theirs, migrate the payment system to use theirs, and then finish the app. In your opinion, or experience, what is the best thing to do?

• Is C# 4.0 Tuple covariant

  - by RichK

  (I would check this out for myself, but I don't have VS2010 (yet)) Say I have 2 base interfaces: IBaseModelInterface IBaseViewInterface And 2 interfaces realizing those: ISubModelInterface : IBaseModelInterface ISubViewInterface : IBaseViewInterface If I define a Tuple<IBaseModelInterface, IBaseViewInterface> I would like to set that based on the result of a factory that returns Tuple<ISubModelInterface, ISubViewInterface>. In C# 3 I can't do this even though the sub interfaces realize the base interfaces. And I'm pretty sure C# 4 lets me do this if I was using IEnumerable<IBaseModelInterface> because it's now defined with the in keyword to allow covariance. So does Tuple allow me to do this? From what (little) I understand, covariance is only allowed on interfaces, so does that mean there needs to be an ITuple<T1, T2> interface? Does this exist?

• What is the problem with this Java code dealing with Generics?

  - by devoured elysium

  interface Addable<E> { public E add(E x); public E sub(E y); public E zero(); } class SumSet<E extends Addable> implements Set<E> { private E element; public SumSet(E element) { this.element = element; } public E getSum() { return element.add(element.zero()); } } It seems that element.add() doesn't return an E extends Addable but rather an Object. Why is that? Has it anything to do with Java not knowing at run-time what the object types really are, so it just assumes them to be Objects(thus requiring a cast)? Thanks

• python json_encode throws KeyError exception

  - by MattM

  In a unit test case that I am running, I get a KeyError exception on the 4th json object in the json text below. I went through the sub-objects and found that it was the "cpuid" object that is the offending object, but I am completely at a loss as to what is wrong with the formatting. response = self.app.post( '/machinestats', params=dict(record=self.json_encode([ {"type": "crash", "instance_id": "xxx", "version": "0.2.0", "build_id": "unknown", "crash_text": "Gah!"}, {"type": "machine_info", "machine_info": "I'm awesome.", "version": "0.2.0", "build_id": "unknown", "instance_id": "yyy"}, {"machine_info": "Soup", "crash_text": "boom!", "version": "0.2.0", "build_id": "unknown", "instance_id": "zzz", "type": "crash"}, {"build_id" : "unknown", "cpu_brand" : "intel", "cpu_count" : 4, "cpuid": { "00000000": {"eax" :123,"ebx" :456, "ecx" :789,"edx" :321}, "00000001": {"eax" :123,"ebx" :456, "ecx" :789,"edx" :321}}, "driver_installed" : True, "instance_id" : "yyy", "version" : "0.2.0", "machine_info" : "I'm awesome.", "os_version" : "linux", "physical_memory_mib" : 1024, "product_loaded" : True, "type" : "machine_info", "virtualization_advertised" : True} ])))

• Implementing Google Search Appliance results into website

  - by Adam Jenkin

  I’m interested to hear peoples preferred methods or approaches to implementing the search results from a Google Search Appliance into an existing website. More specifically how do people prefer to implement/embed the search results into their existing site and persist the surrounding website elements (menus, membership etc) around the search results. As far as I am aware there are 3 different approaches. Sub-domain, handle everything in the xslt – create a search.mysite.com which is completely handled by google xslt and embed surround site components in xslt. Embed search results into existing site using an iframe – Use the existing website and just use an iframe to import results into page. Embed results into existing site by using server side processing – This is how I have previously integrated search into a site using a combination of bespoke dev and the GSALib project. I would be interested to hear if anyone has other suggestions, and were people have benefited or regretted using the above approaches.

• Creating/Handling events for controls when added during runtime.

  - by AllStar11

  I am using a Repeater which contains a placeholder. The placeholder is bound to my database and each ItemTemplate contains 1-6 radiobuttons depending on what the database returns. What I need to do is somehow keep track of which one of the radiobuttons is checked for each question so I can write the user's answers to the database when they complete the test, any ideas?? <asp:Repeater ID="Repeater1" OnItemDataBound="R1_ItemDataBound" runat="server"> <ItemTemplate> <asp:PlaceHolder ID="phAnswers" runat="server"> </asp:PlaceHolder> </ItemTemplate> </asp:Repeater> Sub R1_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs) Dim tempPH As PlaceHolder tempPH = e.Item.FindControl("phAnswers") For x As Integer = 0 To (t_MC.Count - 1) newRadio = New RadioButton newRadio.ID = "Answer" + x.ToString newRadio.GroupName = "Answer" + tempQuestion.ID.ToString newRadio.Text = t_MC(x).Value newRadio.Width = 800 tempPH.Controls.Add(newRadio)

• extracting a quadrilateral image to a rectangle

  - by Will

  In the image below, the sign on the side of the van is not face-on to the camera. I want to calculate, as best I can with the pixels I have, what it'd look like face on. I imagine that this is some kind of loop through the x and y axis doing a Bresenham's line on both dimensions at once with some kind of mixing when pixels in the source image overlap - some sub-pixel mixing of some sort? What approaches are there, and how do you mix the pixels? Is there a standard approach for this?

• How can I expose a service bus by a wcf service to be consumed by a silverlight client

  - by illdev

  In a Silverlight application, instead of consuming and writing (wcf) wrappers around messages that finally get sent to the bus, I want to send use my message bus as directly as possible. My idea was to expose the service bus directly as a wcf service, or, in other terms, I want to bidirectionally pub/sub over the wire. Has this been done already? Is bi-directionality doable at all? After all, we are (are we restricted to that?) in the http domain? Lots of questions. Some head start would be greatly appreciated! I am in .NET land, with using Rhino Service Bus, but the pattern should apply to different platforms.

• how to create a new variant in bjam

  - by steve jaffe

  I've tried reading the documentation but it is rather impenetrable so I'm hoping someone may have a simple answer. I want to define a new 'variant', based on 'debug', which just adds some macro definitions to the compiler command line, eg "-DSOMEMACRO". I think I may be able to do this as a "sub-variant" of debug, or else just define a new variant copying 'debug', but I'm not even sure where to do this. It looks like feature.jam in $BOOST_BUILD_DIR/build may be the place. Perhaps what I really want is simply a new 'feature' but it's still not clear to me exactly what I need to do and where, and I don't know if a 'feature' allows me to direct the build products to a different directory to the 'debug' build. Any suggestions will be appreciated. (In case you're wondering, I have to use bjam since it has been adopted as our corporate standard.)

• Javascript: Using the Module Pattern for larger projects

  - by Rob

  I'm interested in using the Module Pattern to better organize my future projects. Unfortunately, there are only a few brief tutorials and proof-of-concept examples of the Module Pattern. Using the module pattern, I would like to organize projects into this sort of structure: project.arm.object.method(); Where "project" is my global project name, "arm" is a sub-section or branch of the project, "object" is an individual object, and so on to the methods and properties. However, I'm not sure how I should be declaring and organizing multiple "arms" and "objects" under "project". var project = window.project || {}; project.arm = project.arm || {}; project.arm.object = (function() { var privateVar = "Private contents."; function privateMethod() { alert(privateVar); } return { method: privateMethod }; }()); Are there any best practices or conventions when defining a complex module structure? Should I just declare a new arm/object underneath the last?

• Implement subitem in SQLite

  - by Mohit Deshpande

  How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a parent task. How would I implement this in SQLite for Android? NOT IN SQL! So no foreign keys (triggers are allow, though)! Could I just have a separate table (subtask) and have a foreign key trigger to link subtask(INTEGER parent) to task(INTEGER PRIMARY KEY AUTOINCREMENT _id)? Or should I add a column to my original task table(INTEGER parent)? How could I implement this?

• What's a good Perl OO interface for creating and sending email?

  - by aidan

  I'm looking for a simple (OO?) approach to email creation and sending. Something like $e = Email->new(to => "test <[email protected]>", from => "from <[email protected]>"); $e->plain_text($plain_version); $e->html($html_version); $e->attach_file($some_file_object); I've found Email::MIME::CreateHTML, which looks great in almost every way, except that it does not seem to support file attachments. Also, I'm considering writing these emails to a database and having a cronjob send them at a later date. This means that I would need a $e->as_text() sub to return the entire email, including attachments, as raw text which I could stuff into the db. And so I would then need a way of sending the raw emails - what would be a good way of achieving this? Many thanks

There will be about 40 users per site. the two options I'm trying to decide between are have a central website running the php and directing the users off to their own database using sub domains for each user each with their own php in htdocs I dont even know if 2 is possible/stupid but if it was, would it make any difference to performance as they're all being run by the same server.
