• customizing Django look and feel in Python

  - by user248237

  I am learning Django and got it to work with wsgi. I'm following the tutorial here: http://docs.djangoproject.com/en/1.1/intro/tutorial01/ My question is: how can I customize the look and feel of Django? Is there a repository of templates that "look good", kind of like there are for Wordpress, that I can start from? I find the tutorial counterintuitive in that it goes immediately toward customizing the admin page of Django, rather than the main pages visible to users of the site. Is there an example of a "typical" Django site, with a decent template, that I can look at and built on/modify? The polls application is again not very representative since it's so specialized. any references on this would be greatly appreciated. thanks.

• How to change the app name in OSX menubar in a pure-Python application bundle?

  - by gyim

  I am trying to create a pure-Python application bundle for a wxPython app. I created the .app directory with the files described in Apple docs, with an Info.plist file etc. The only difference between a "normal" app and this bundle is that the entry point (CFBundleExecutable) is a script which starts with the following line: #!/usr/bin/env python2.5 Everything works fine except that the application name in the OSX menubar is still "Python" although I have set the CFBundleName in Info.plist (I copied the result of py2app, actually). The full Info.plist can be viewed here: http://tinyurl.com/32qgpjt How can I change this? I have read everywhere that the menubar name is only determined by CFBundleName. How is it possible that the Python interpreter can change this in runtime? Note: I was using py2app before, but the result was too large (50 MB instead of the current 100KB) and it was not even portable between Leopard and Snow Leopard... so it seems to be much easier to create a pure-Python app bundle "by hand" than transforming the output of py2app.

• iPhone - UIScrollView is scrolling before UIDatePicker that is placed inside it

  - by Oliver

  Hello, I have a UIDatePicker inside a UIScrollView. But the UIDatePicker does not respond to scroll touches. It's the scrollview that is scrolling. Reading some docs on the net, I've set "Delay Content Touches" to NO, an now I see the datepicker starting a slight scroll, but it's still the scrollview that take the final word. I have some place on the screen where the user can touch to scroll the view. So how may I separate the two kind of scrolls ans make the datepicker scroll in a normal way ? Thank you for your help

• Google app engine sessions now supported???

  - by user246114

  Hi, I thought google app engine did not support sessions (last time I checked was a few months ago). Now I was searching again for it and saw this: http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions says it supports: javax.servlet.http.HttpSession does this mean we have servlet session support now? If so, does anyone have an example of using this? I wanted to create my own User class and support user login and session management (I know app engine already supports this for google users, but wanted my own users for various requirements) Thanks!

• Android remote code loading

  - by sehugg

  I am developing a library for Android that requires frequent updates from a central server. I was thinking how nice it would be if my library could update itself -- or if I could just release a bootstrap library that downloads the target library when the app is installed. I see this class in 1.5 called "DexClassLoader" but there seems to be precious little on the web besides the API docs. Has anyone used this successfully for the scenario which I described? Also, do the terms of the Android Market permit such a thing?

• jquery ui dialog - live not working?

  - by ile

  I'm using this dialog: http://docs.jquery.com/UI/Dialog To open dialog I do it this way: $('a.openModal').live("click", function() { var idArr = $(this).attr('id').split("OpenNote"); var id = idArr[1]; alert($(".modalNote#dialog-modal" + id).html()); $(".modalNote#dialog-modal" + id).dialog('open'); return false; }); This dialog is used to display content of note when title is clicked. When I generated html on pageload, then this works fine, but if I add html dynamically then dialog won't open. It is also not hidden when it's appended to div. Is it possible to open it "on-fly"?

• DispatcherOperations.Wait()

  - by Mark

  What happens if you call dispatcherOperation.Wait() on an operation that has already completed? Also, the docs say that it returns a DispatcherOperationStatus, but wouldn't that always be Completed since it (supposedly) doesn't return until it's done? I was trying to use it like this: private void Update() { while (ops.Count > 0) ops.Dequeue().Wait(); } public void Add(T item) { lock (sync) { if (dispatcher.CheckAccess()) { list.Add(item); OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item)); } else { ops.Enqueue(dispatcher.BeginInvoke(new Action<T>(Add), item)); } } } I'm using this in WPF, so all the Add operations have to occur on the UI thread, but I figured I could basically just queue them up without having to wait for it to switch threads, and then just call Update() before any read operations to ensure that the list is up to date, but my program started hanging.

• Google Gears hangs when capturing (unmanaged resource store)

  - by Gus

  Our code was written based on the example from Google Gears' own docs. We're using an unmanaged resource store. So we declare the files in an array, create the store, and capture all the files. Trouble is, the capturing process hangs. It always hangs on a random file (no discernible pattern has emerged), and when you reload the page, it always successfully captures. We're capturing 48 files. It seems to have nothing to do with the files themselves, as it hangs on every file type. I've seen it hang on the 6th file or the 47th. Windows and Mac. FF, IE, and Safari. We are not using a WorkerPool, and I'm thinking this may be necessary. Any other ideas why it would hang?

• Tabulated log file format with the python logging system

  - by yorjo

  Hi everybody, I'm using the python logging module with the "native" configuration file support (config.fileconfig) as describe in the documentation here : http://docs.python.org/library/logging.html (see the logging.conf file) I was wondering if it's possible to supply a tabulated data format in the configuration file? The sample configuration file is the following: [formatter_simpleFormatter] format=%(asctime)s - %(name)s - %(levelname)s - %(message)s I though that using the \t in the format would be enough but it doesn't. format=%(asctime)s\t%(name)s\t%(levelname)s\t%(message)s\t If I do so it print \t in the result. I tried a couple of thing without success. I suppose it's really easy to do but I don't find it! How can I do that?

• Can you pull the connectionString for a log4net AdoNetAppender from elsewhere in a web.config file?

  - by mrsharps

  Hey all. This is my first StackOverflow question. I'm already have a db connection string in my web.config file. I scanned the log4net docs, but can't seem to find a way to use it within the log4net section of my web.config file. Is is possible to do something like this? <connectionStrings> <add name="connStr" connectionString="Data Source=localhost; ..." /> </connectionStrings> <log4net> <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender"> <connectionString connectionStringName="connStr"/> ... </log4net> Thanks!

  - by Nishant Kumar

  Hi, I want to access the messages stored in inbox through my android project. I have tried the method of forming URI for sms (content://sms/ inbox) and then quering it for various parametres.

• How to track dealloc of an abstract object class (NSMutable...)

  - by Thomas Tempelmann

  I have a bug in my code caused by a premature freeing of a ObjC object. I seem not to be able to find it by just looking at my code. There's usually a simple trick to track the dealloc to any class: Implement dealloc, and set a breakpoint. This even usually works with standard objects, by subclassing them and making sure I instantiate the subclass instead of the standard class. However, this does not seem to work with NSMutableArray, and probably neither with similar NSMutable... classes. Some explanations for this can be found here: link text Any other ideas how to track the dealloc invocation of a particular class or object so that I can see the call stack? It's probably possible with DTrace. Any pointers without having to read the entire dtrace docs first?

• Persisting non-entity class that extends an entity (jpa) - example?

  - by Michal Minicki

  The JPA tutorial states that one can have a non-entity that extends entity class: Entities may extend both entity and non-entity classes, and non-entity classes may extend entity classes. - http://java.sun.com/javaee/5/docs/tutorial/doc/bnbqa.html Is it possible to persist such structure? I want to do this: @Entity abstract class Test { ... } class FirstConcreteTest extends Test { ... } // Non-ntity class SecondConcreteTest extends Test { ... } // Non-entity Test test = new FirstConcreteTest(); em.persist(test); What I would like it to do is to persist all fields mapped on abstract Test to a common database table for all concrete classes (first and second), leaving all fields of first and second test class unpersisted (these can contain stuff like EJBs, jdbc pools, etc). And a bonus question. Is it possible to persist abstract property too? @Entity abstract class Test { @Column @Access(AccessType.PROPERTY) abstract public String getName(); } class SecondConcreteTest extends Test { public String getName() { return "Second Concrete Test"; } }

• Annotations: methods vs variables

  - by Zenzen

  I was always sure (don't know why) that it's better to add annotations to variables, but while browsing the Hibernate doc http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-hibspec-collection I noticed they tend to annotate the methods. So should I put my annotations before methods, like this: @Entity public class Flight implements Serializable { private long id; @Id @GeneratedValue public long getId() { return id; } public void setId(long id) { this.id = id; } } Or is it better to do it like this: @Entity public class Flight implements Serializable { @Id @GeneratedValue private long id; public long getId() { return id; } public void setId(long id) { this.id = id; } } Or maybe there's no difference?

• Is there a difference between NSString compare: and isEqual(ToString): ?

  - by frenetisch applaudierend

  Occasionally I find code which tests if two NSStrings are the same like this: if ([str1 compare:str2] == NSOrderedSame) { // Do something } Now, I believe this is less readable than using isEqualToString: and it also has some nasty side effects, like if str1 == nil the if(..) evaluates to true, or when str2 == nil havoc might break upon us according to the Apple docs. But before I crusade against those statements in my companys code, I wanted to make sure I didn't miss some important point. So my question basically boils down to: Is there any difference between a compare: to NSOrderedSame and isEqual:?

• Merging tables in MySQL - sum up columns

  - by Alan Williamson

  I have an interesting problem, that i am sure has a simple answer, but i can't seem to find it in the docs. I have two separate database tables, on different servers. They are both identical table schema with the same primary keys. I want to merge the tables together on one server. But, if the row on Server1.Table1 exists in Server2.Table2 then sum up the totals in the columns i specify. Table1{ column_pk, counter }; "test1", 3 "test2", 4 Table2{ column_pk, counter }; "test1", 5 "test2", 6 So after i merge i want: "test1",8 "test2",10 Basically i need to do a mysqldump but instead of it kicking out raw INSERT statements, i need to do a INSERT..ON DUPLICATE KEY UPDATE statements. What are my options? Appreciate any input, thank you

• Integer v/s int

  - by Siddhartha

  Read this on the oracle docs java.lang page: Frequently it is necessary to represent a value of primitive type as if it were an object. The wrapper classes Boolean, Character, Integer, Long, Float, and Double serve this purpose. I'm not sure I understand why these are needed. It says they have useful functions such as equals(). But if I can do (a==b), why would I ever want to declare them as Integer, use more memory and use equals()? How does the memory usage differ for the 2?

• iPhone audio Filter Question

  - by Joe

  Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

• Using code from this site

  - by user553798

  Hi, The legal section of this site mentions that all code by the contributors is licensed under the Creative Commons Attribution Share Alike License. Does this mean that I have to attribute the submitter even if the code in question is a few lines amongst hundreds or thousands of lines of code? What if I use code from a book or SDK? For eg; If I use the sample code from Google's Android SDK documentation, does that mean I need to attribute Google every time I write an app, after all it would be impossible to write an app without consulting the SDK docs, atleast initially... I am totally confused :S

• Allowing pop-up's and downloads with flex

  I'm building an flex app that is basically a wrapper for a few websites.

• Open two new tabs using Javascript

  - by Permana

  I have this situation: There are a login page with a login form (form action is $_SERVER['PHP_SELF']). When user login, it will check what application the user can access and open all the application that available for that user in new tab. If user can access application (for example) 'Docs' and 'Sites', it will open 2 tabs. I Open new tab using window.open('app1.html','_newhtml');, some people say that it only works in Firefox. It's OK, no big deal for me. The problem is, It only open 1 tab, although I write it 2 times window.open('app1.html','_newhtml'); window.open('app2.html','_newhtml'); How can I open 2 tabs? are there any hacks from server side or client side programming?

• Are volatile data members trivially copyable?

  - by Lightness Races in Orbit

  Whilst writing this answer I realised that I'm not as confident about my conclusions as I usually would ensure before hitting Post Your Answer. I can find a couple of reasonably convincing citations for the argument that the trivial-copyability of volatile data members is either implementation defined or flat-out false: https://groups.google.com/forum/?fromgroups=#!topic/comp.std.c++/5cWxmw71ktI http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48118 http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3159.html#496 But I haven't been able to back this up in the standard1 itself. Particularly "worrying" is that there's no sign of the proposed wording change from that n3159 issues list in the actual standard's final wording. So, what gives? Are volatile data members trivially copyable, or not? 1   C++11

• Solr match all aka *:* does not work

  - by Karussell

  Don't know what I did wrong. I have two indices with identical documents in it. The local index was replicated from a master which responds correctly, so the same solrconfig.xml and schema.xml file. But if I query the index on my local machine with *:* I get 0 docs. (other queries on my local machine are working correct) I tried jetty and tomcat for the local index. no success. The *:* behaviour is crucial for me, because some test cases are failing now. Do you have an idea what could be wrong?
