• Django query to get a unique set based on a particular column's value

  - by kchau

  Hope this makes sense... Is there a simple way to return a set of values from a table based on a single column's values being distinctly unique? What I'm hoping for is something like: SegCode.query.filter(ref.unique()).only('ref') That's not real code, but I was hoping there was some simple function out there that will accomplish this...

• jQuery cannot retrieve data from localhost

  - by fatnic

  I have a very simple bit of jQuery to retrieve my latest Tweet $.getJSON("http://twitter.com/statuses/user_timeline/username.json?count=1", function(data) { $("#tweet_text").html(data[0].text); }); This works fine on a simple HTML file on my desktop. However, once the file is accessed from my localhost (apache) no data is being returned. I was wondering if any part of Apache was blocking the request somehow? Or any other ideas?

• JSON serialization of Google App Engine models

  - by user111677

  I've been search for quite a while with no success. My project isn't using Django, is there a simple way to serialize App Engine models (google.appengine.ext.db.Model) into JSON or do I need to write my own serializer? My model class is fairly simple. For instance: class Photo(db.Model): filename = db.StringProperty() title = db.StringProperty() description = db.StringProperty(multiline=True) date_taken = db.DateTimeProperty() date_uploaded = db.DateTimeProperty(auto_now_add=True) album = db.ReferenceProperty(Album, collection_name='photo') Thanks in advance.

  - by ThePower

  I need an simple way to check whether a string that is sent to my function is of the form: (x + n)(x + m) //the +'s can be minus' //n and m represent a double //x represents the char 'x' Is there a simple string format that I can use to check that this is the form. As opposed to checking each character singularly. The whitespace will be removed to save any confusion. Regards Lloyd

• Installation of Jetty into Eclipse

  - by Claus Jørgensen

  Hi I've had Jetty recommended as a good container for fast and simple development, in my case, Java Server Faces. I wish to use it with my Eclipse IDE (Version: 3.4.1), but quite frankly, can't figure out how. I've tried various outdated plugins, only with large amounts of errors in return, so I'm hoping someone could guide me from downloading the right version to installing it, and being able to press "RUN", and see a simple Hello World in JSP/JSF work. Cheers.

• `strip`ing the results of a split in python

  - by Igor

  i'm trying to do something pretty simple: line = "name : bob" k, v = line.lower().split(':') k = k.strip() v = v.strip() is there a way to combine this into one line somehow? i found myself writing this over and over again when making parsers, and sometimes this involves way more than just two variables. i know i can use regexp, but this is simple enough to not really have to require it...

  Does anybody have a PHP (or other language) script for drawing a spiral. A simple (Archimedean spiral) would be just fine. Of course the principle is simple but coding it in SVG or GD would take some time, so I wonder if somebody has one ready :-)

• Creating a zip archive of the maven "target" directory

  - by Yaneeve

  Hi all, I am wish to create a zip archive of my "target" directory (${project.build.directory). using the maven-assembly-plugin seems to me like overkill for such a simple task (and a bit complicated - why must I use another file, the assembly descriptor, for such a task) I can't locate the seemingly more simple maven-zip-plugin in the http://repo1.maven.org/maven2 repository. Any input?

• Creating an intro followed by a loop

  - by voodoo555

  Hey everybody, I just recorded some song and cut it into two parts. The first part contains an intro and the second is supposed to loop. What I want to do now, is to have a simple graphical animation (5 keyframes or so) that loops as well, while the music plays along. There's probably a simple solution to it, when you're familiar with AS. Unfortunately this is the first thing I've ever tried to do with Flash. I'm using Flash CS4. Greetings

• Database that consumes less disk space

  - by Hugo Palma

  I'm looking at solutions to store a massive quantity of information consuming the less possible disk space. The information structure is very simple and the queries will also be very simple. I've looked at solutions like Apache Cassandra and relations databases but couldn't find a comparison where disk usage is mentioned. Any ideas on this would be great.

• New to Android - Drawing a view at runtime

  - by Brian515

  HI all, I'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here. Thanks in advance!
