• Django choking oddly on some static media

  - by Edan Maor

  My situation: I'm serving static media via Django on my dev machine. On some files that I try and load, I get back this error: Traceback: File "c:\Program Files\Python26\Lib\site-packages\django\core\handlers\base.py" in get_response 92. response = callback(request, *callback_args, **callback_kwargs) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\views.py" in userpage 71. so_user = site.user(userid) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\stackexchange.py" in user 476. u, = self.users((nid,), **kw) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\stackexchange.py" in users 481. return self._get(User, ids, 'users', kw) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\stackexchange.py" in _get 471. return self.build(root, typ, coll, kw) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\stackexchange.py" in build 448. json = self._request(url, kw) File "E:\Stack2Blog\src.hg\stack2blog\..\stack2blog\stack2blogapp\stackexchange.py" in _request 422. dump = json.load(data) File "c:\Program Files\Python26\lib\json\__init__.py" in load 264. return loads(fp.read(), Exception Type: AttributeError at /userpage/362498 Exception Value: 'str' object has no attribute 'read' I've traced it to specific files which don't work (by going to their specific urls). Here's the odd part: changing the filename of the files makes them suddenly work. For example, I had a file called 'post.jpg', which gave this error. I renamed it to 'pos.jpg' and it worked. Back to 'post.jpg' and it gives the same error.

• C# Virtual method call in constructor - how to refactor?

  - by Cristi Diaconescu

  I have an abstract class for database-agnostic cursor actions. Derived from that, there are classes that implement the abstract methods for handling database-specific stuff. The problem is, the base class ctor needs to call an abstract method - when the ctor is called, it needs to initialize the database-specific cursor. I know why this shouldn't be done, I don't need that explanation! This is my first implementation, that obviously doesn't work - it's the textbook "wrong way" of doing it. The overridden method accesses a field from the derived class, which is not yet instantiated: public abstract class CursorReader { private readonly int m_rowCount; protected CursorReader() { m_rowCount = CreateCursor(sqlCmd); //virtual call ! } protected abstract int CreateCursor(string sqlCmd); } public class SqlCursorReader : CursorReader { private SqlConnection m_sqlConnection; public SqlCursorReader(string sqlCmd, SqlConnection sqlConnection) { m_sqlConnection = sqlConnection; //field initialized here } protected override int CreateCursor(string sqlCmd) { //uses not-yet-initialized member *m_sqlConnection* //so this throws a NullReferenceException var cursor = new CustomCursor(sqlCmd, m_sqlConnection); return cursor.Count(); } } I will follow up with an answer on my attempts to fix this...

• access JRUN jndi environment vaiables from coldfusion (java)

  - by jake

  I want to put some instance specific configuration information in JNDI. I looked at the information here: http://www.adobe.com/support/jrun/working_jrun/jrun4_jndi_and_j2ee_enc/jrun4_jndi_and_j2ee_enc03.html I have added this node to the web.xml: <env-entry> <description>Administrator e-mail address</description> <env-entry-name>adminemail</env-entry-name> <env-entry-value>[email protected]</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> In coldfusion I have tried several different approaches to querying the data: <cfset ctx = createobject("java","javax.naming.InitialContext") > <cfset val = ctx.lookup("java:comp/env") > That lookup returns a jrun.naming.JRunNamingContext. If i preform a lookup on ctx for the specific binding I am adding I get an error. <cfset val = ctx.lookup("java:comp/env/adminemail") > No such binding: adminemail Preforming a listBindings returns an empty jrun.naming.JRunNamingEnumeration. <cfset val = ctx.listBindings("java:comp/env") > I only want to put a string value (probably several) into the ENC (or any JNDI directory at this point).

• uefa.com is a great website

  - by olst

  Hi all. I was wondering if anyone knows in what technology/web platform the uefa.com website was built. Its page suffix is ".html", but I don't see how it could be built with just html, since it probably has a lot of dynamic content... Anyway, it's a great website with fast loading pages and nice design. Does anyone know who built it ? ... thanks ...

• Creating a complex tree model in Qt

  - by Zeke

  I'm writing an IRC Client (yes another one). Long story short. I'm writing a Server dialogue that keeps a list of this: Identity Networks Channels Addresses I have 3 different list views that will be for the Networks, Channels and Addresses. When the user changes the Identity (combo box). The network listview will lookup all the networks for that specific Identity. After it loads up the Networks it will automatically select the first network and then load all the channels and addresses for that specific network. The problem is I want to have 3 views for 1 model, to minimise all the memory and the loading of data. So that it makes it much easier to manage and not do a bunch of work. If you'd look at QColumnView it's the same exact thing. But I don't need it to be on one exact page since the views are on entirely different tabs to make it easier to go through the Server dialogue. I'm wondering what will be the best way to go about handling this complexity. The information is stored in a SQLite database. I already have the classes written to extract and store it. Just the modelling is the painful part of this solution.

• How does porting between Linux and Windows work?

  - by Matt

  If a particular piece of software is made to be run on one platform and the programmer/company/whatever wants to port it to the other, what exactly is done? I mean, do they just rewrite linux or windows-specific references to the equivalent in the other? Or is an entire rewrite necessary? Just trying to understand what makes it so cost-prohibitive that so many major vendors don't port their software to Linux (specifically thinking about Adobe) Thanks

• Why doesn't java.util.Set have get(int index)?

  - by Marty Pitt

  I'm sure there's a good reason, but could someone please explain why the java.util.Set interface lacks get(int Index), or any similar get() method? It seems that sets are great for putting things into, but I can't find an elegant way of retrieving a single item from it. If I know I want the first item, I can use set.iterator().next(), but otherwise it seems I have to cast to an Array to retrieve an item at a specific index? What are the appropriate ways of retrieving data from a set? (other than using an iterator) I'm sure the fact that it's excluded from the API means there's a good reason for not doing this -- could someone please enlighten me? EDIT: Some extremely great answers here, and a few saying "more context". The specific scneario was a dbUnit test, where I could reasonalby assert that the returned set from a query had only 1 item, and I was trying to access that item. However, the question is more valid without the scenario, as it remains more focussed : What's the difference between set & list. Thanks to all for the fantastic answers below.

• ASP MVC Controller Method not always called from $.getJSON request

  - by johnvpetersen

  I have a controller method that returns a jSON object and in one calling situation, it works and in another calling situation, it does not work. When the URL in my browser is this: http://localhost:65247/Client -- it works. But, when my url looks like this: http://localhost:65247/Client/UserAdmin?id=6 -- it DOES NOT work In a nutshell, clients have users. From within the client, I wish to work on a specific user (this is the UserAdmin view). In this case, the client id is 6. From within the UserAdmin view that was launched with Id=6, I then wish to select a user from a dropdown. The idea was to use javascript and $.getJSON to fetch data for the specific user so as not to have to refresh the entire page. I use this approach in other parts of the app. The only difference I can see is with the URL in the browser. It would appear the presence of parameters via the '?' is futzing things up a bit. Any ideas?? Thanks in advance. John

• Looking for similar projects: Iphone/Android + Google Maps + "external" database = sightseeing map

  - by sniurkst

  Hello, sorry, it's not exactly a programming question, but I am currently in a research state and looking for similar projects, so I could analyze them: It should be application to iPhone or Android or other mobile platform, where, basically, user can access map with "places of interest" and add it's own "place of interest" (with photo and description). Kind of, community generated sightseeing map. I know it is quite simple and not a groundbreaking idea, but my google-fu is quite weak and I can't find anything like that.

• Are there any good e-commerce extensions/plugins for Umbraco?

  - by JasonS

  I'm working on a project that will use Umbraco for CMS capability, but also has a fairly simple ecommerce requirement. I'm aware of Commerce4Umbraco, are there others? Or, should I look elsewhere for simple e-commerce functionality. Would be nice to use the same platform for CMS and e-commerce... stuck with Umbraco though.

• Consolidate multiple site files into single location

  - by seengee

  We have a custom PHP/MySQL CMS running on Linux/Apache thats rolled out to multiple sites (20+) on the same server. Each site uses exactly the same CMS files with a few files for each site being customised. The customised files for each site are: /library/mysql_connect.php /public_html/css/* /public_html/ftparea/* /public_html/images/* There's also a couple of other random files inside /public_html/includes/ that are unique to each site. Other than this each site on the server uses the exact same files. Each site sitting within /home/username/. There is obviously a massive amount of replication here as each time we want to deploy a system update we need to update to each user account. Given the common site files are all stored in SVN it would make far more sense if we were able to simply commit to SVN and deploy to a single location direct from there. Unfortunately, making a major architecture change at this stage could be problematic. In my mind the ideal scenario would mean creating an account like /home/commonfiles/ and each site using these common files unless an account specific file exists, for example a request is made to /home/user/public_html/index.php but as this file doesnt exist the request is then redirected to /home/commonfiles/public_html/index.php. I know that generally this approach is possible, similar to how Zend Framework (and probably others) redirect all requests that dont match a specific file to index.php. I'm just not sure about how exactly to go about implementing it and whether its actually advisable. Would really welcome any input/ideas people have got. Thanks.

• "Home" of Javascript similar to python.org?

  - by drewk

  Perl, Ruby, Python, Javascript / ecmascript, PHP are all similar in the sense of being open source, open documentation, multi-platform, etc. Perl has http://www.perl.org Ruby has http://www.ruby-lang.org Python has http://www.python.org PHP has http://php.net Is there a "home" for javascript in the same sense as these other languages? When I say "home" I mean the go-to place for official documentation, specifications, source code of the language, examples, etc.

• Mac OSX Programming for long time Linux geek

  I've written software on Linux since 1995 but must get up to speed with app development on the Mac. I have no experience on that platform. Obviously I should get my hands on some appropriate hardware. What are good books, tutorial websites, and other resources for experienced devs getting started on Mac? Not just APIs and app internals, but also including how does one install an app, debug it, etc?

• Getting RAW Soap Data from a Web Reference Client running in ASP.net

  - by Harry

  I'm trying to trouble shoot a web service client in my current project. I'm not sure of the platform of the Service Server (Most likely LAMP). I believe there is a fault on their side of the fence as i have eliminated the potential issues with my client. The client is a standard ASMX type web reference proxy auto generated from the service WSDL. What I need to get to is the RAW SOAP Messages (Request and Responses) What is the best way to go about this?

• master pages, form pages, form runat=server > all onclick methods on master page?

  - by b0x0rz

  the problem i have is that i have multiple nested master pages: level 1: global (header, footer, login, navigation, etc...) level 2: specific (search pages, account pages, etc...) level 3: the page itself now, since only one form can have runat=server, i put the form at global page (so i can handle things like login, feedback, etc...). now with this solution i'd have to also put the for example level 3 (see above) methods, such as search also on the level 1 master page, but this will lead to this page being heavy (for development) with code from all places, even those that are used on a single page only (change email form for example). is there any way to delegate such methods (for example: ChangeEMail) from level 1 (global masterpage) to level 3 (the single page itself). to be even more clear: i want to NOT have to have the method ChangeEMail on the global master page code behind, but would like to 'MOVE' it somehow to the only page that will actually use it. the reason why it currently has to be on the global master is that global master has form runat=server and there can be only one of those per aspx page. this way it will be easier (more logical) to structure the code. thnx (hope i explained it correctly) have searched but did not find any general info on handling this case, usualy the answer is: have all the methods on the master page, but i don't like it. so ANY way of moving it to the specific page would be awesome. thnx

  I just read that Android has a 450% performance improvement because it added a JIT compiler, I know what JIT is, but I don't really understand why is it faster than normal compiled code? or what's the difference with the older approach from the Android platform (the Java like run compiled bytecode).
