• django ManyToMany through help

  - by dotty

  Hay I've got a question about relationships. I want to Users to have Friendships. So a User can be a friend with another User. I'm assuming i'll need to use the ManyToManyField, through a Friendship table. But i cannot get it to work. Any ideas? Here are my models. class User(models.Model): username = models.CharField(max_length=999) password = models.CharField(max_length=999) created_on = models.DateField(auto_now = False, auto_now_add = True) updated_on = models.DateField(auto_now = True, auto_now_add = False) friends = models.ManyToManyField('User', through='Friendship') class Friendship(models.Model): user = models.ForeignKey('User') friend = models.ForeignKey('User') Thanks

• How can we calculate sea distances using waypoints ?

  - by Ashish Ranpara

  Hi Friends, I have one query in which I really stuck at that. I have port database with waypoints and also routing points which I need to use in distance calculation between two ports. I have done lots of R&D to find formula which gives me distance between two points. I also need shortest route which is possible. I have reviewed online tools which allow user to calculate the distance. But I want to do the same at my own. I have reviewed Port World Distance Calculator. I reviewed the Great Circle formula to achieve that but I don't know that how we avoid landscapes in sea distance and in which direction I need to find distance for second port.

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• SEO friendly CMS with user profile functionality

  - by kjgilla

  My company has a project to create a magazine style site with user profile functionality. We need: CMS for the article publishing. SEO Friendly urls. Commenting capability for the published articles. User profile system with limited social networking functionality (friends,friend messages,blog,account tweaking/personalization, article commenting) My area of expertise is asp.net, particularly MVC. I have read similar posts on this site regarding CMS with MVC and I'm surveying the landscape (N2, Kooboo, MvcCms, etc). What I am really interested in knowing is whether there are any platforms out there (WAMP or LAMP) that provide this functionality out of the box. I may be willing to go the LAMP route if it requires little development work. If I have to crack open any code then it probably needs to be .net unless there are compelling reasons to go another route.

• Setup GIT Server with Msysgit on Windows

  - by Tom

  Hi Guys, My friends and I are trying to setup GIT for windows using this tutorial but we just keep running into problems. I know many of you guys on this site are GIT gurus - so I was wondering whether anyone would be able to help us (and I am sure 100s of other Windows Devs who want to use GIT) write a "Setup GIT Server" guide for windows using Msysgit ? There is a comment on the guide above suggesting it cant be done with Msysgit because gitosis requires the use of an SSH Server and Bash ? Would really appreciate it if someone could do a step by step guide as there is not one available (we've search for hours)? Install Mysisgit ? Thx

• MongoMapper, Rails, Increment Works in Console but not Controller

  - by Michael Waxman

  I'm using mongo_mapper 0.7.5 and rails 2.3.8, and I have an instance method that works in my console, but not in the controller of my actual app. I have no idea why this is. #controller if @friendship.save user1.add_friend(user2) ... #model ... key :friends_count, Integer, :default => 0 key :followers_count, Integer, :default => 0 def add_friend(user) ... self.increment(:friends_count => 1) user.increment(:followers_count => 1) true end And this works in the console, but in the controller it does not change the follower count, only the friends count. What gives? The only thing I can even think of is that the way that I'm passing the user in is the problem, but I'm not sure how to fix it.

• running multi threads in Java

  - by owca

  My task is to simulate activity of couple of persons. Each of them has few activities to perform in some random time: fast (0-5s), medium(5-10s), slow(10-20s) and very slow(20-30s). Each person performs its task independently in the same time. At the beginning of new task I should print it's random time, start the task and then after time passes show next task's time and start it. I've written run() function that counts time, but now it looks like threads are done one after another and not in the same time or maybe they're just printed in this way. public class People{ public static void main(String[] args){ Task tasksA[]={new Task("washing","fast"), new Task("reading","slow"), new Task("shopping","medium")}; Task tasksM[]={new Task("sleeping zzzzzzzzzz","very slow"), new Task("learning","slow"), new Task(" :** ","slow"), new Task("passing an exam","slow") }; Task tasksJ[]={new Task("listening music","medium"), new Task("doing nothing","slow"), new Task("walking","medium") }; BusyPerson friends[]={ new BusyPerson("Alice",tasksA), new BusyPerson("Mark",tasksM), new BusyPerson("John",tasksJ)}; System.out.println("STARTING....................."); for(BusyPerson f: friends) (new Thread(f)).start(); System.out.println("DONE........................."); } } class Task { private String task; private int time; private Task[]tasks; public Task(String t, String s){ task = t; Speed speed = new Speed(); time = speed.getSpeed(s); } public Task(Task[]tab){ Task[]table=new Task[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.tasks = table; } } class Speed { private static String[]hows = {"fast","medium","slow","very slow"}; private static int[]maxs = {5000, 10000, 20000, 30000}; public Speed(){ } public static int getSpeed( String speedString){ String s = speedString; int up_limit=0; int down_limit=0; int time=0; //get limits of time for(int i=0; i<hows.length; i++){ if(s.equals(hows[i])){ up_limit = maxs[i]; if(i>0){ down_limit = maxs[i-1]; } else{ down_limit = 0; } } } //get random time within the limits Random rand = new Random(); time = rand.nextInt(up_limit) + down_limit; return time; } } class BusyPerson implements Runnable { private String name; private Task[] person_tasks; private BusyPerson[]persons; public BusyPerson(String s, Task[]t){ name = s; person_tasks = t; } public BusyPerson(BusyPerson[]tab){ BusyPerson[]table=new BusyPerson[tab.length]; for(int i=0; i < tab.length; i++){ table[i] = tab[i]; } this.persons = table; } public void run() { int time = 0; double t1=0; for(Task t: person_tasks){ t1 = (double)t.time/1000; System.out.println(name+" is... "+t.task+" "+t.speed+ " ("+t1+" sec)"); while (time == t.time) { try { Thread.sleep(10); } catch(InterruptedException exc) { System.out.println("End of thread."); return; } time = time + 100; } } } } And my output : STARTING.....................

• Sending Facebook notifications

  - by antpaw

  Hey i have a little facebook iframe application written with rails and the facebooker plugin. I can loop through the users friends and see whether they also have this application. To do this I use a fql qeury, and my own html (no fbml). Now i want to create a button right beside every friend who doesn't have this app, that sends an invite massage. Is it possible to do this without this FBML/JS voodoo? I looked through the RESTful api but the only thing i could found was this deprecated method :( Can someone provide me an code example on how to do this? I really don't want to use this FBML stuff because it doesn't fit into the ui concept of the app, but if that the only way, please explain how to do this (every fbml tag I've tried is just invisible :( ) Thanks a lot.

• a missing variable in a switch statement ?!!

  - by mechhfly

  hi folks, i have a strange issue. a variable seems to be missing during a pass through a case statement i have a function like so function checklink($var0, $var1, $var2) { switch($var0) { case "case1": print $var2; //code uses $var2 successfully case "case2": print $var2; //variable has disappeared! } } essentially what i am doing is constructing a string from the last variable based on the first. if i run the code in which the first case is true, i get the expected results, but when i run the second case, my variable seems to have vanished. these first two case statements are syntactically the same and the variable is gathered from the $_GET array (hard coded into hyperlink). any light on this issue? if more explanation is needed let me know, its late and my brain is getting mushy. thanks my friends.

• best way to store 1:1 user relationships in relational database

  - by aharon

  What is the best way to store user relationships, e.g. friendships, that must be bidirectional (you're my friend, thus I'm your friend) in a rel. database, e.g. MYSql? I can think of two ways: Everytime a user friends another user, I'd add two rows to a database, row A consisting of the user id of the innitiating user followed by the UID of the accepting user in the next column. Row B would be the reverse. You'd only add one row, UID(initiating user) followed by UID(accepting user); and then just search through both columns when trying to figure out whether user 1 is a friend of user 2. Surely there is something better?

• How do I free SQLServerCE's COM instance from the current running process?

  - by David Thornley

  It's been a while since I touched COM so be nice ;) This is under WindowsCE 5.0 with SQLServerCE 2.0. After calling this to load SQLServerCE 2.0 : - IDBInitialize *pIDBInitialize = NULL; CoCreateInstance(CLSID_SQLSERVERCE_2_0, NULL, CLSCTX_INPROC_SERVER, IID_IDBInitialize, (void**)&pIDBInitialize); Module load occurs for SSCE20.dll which obviously loads the SQLServerCE engine into the process space. What I don't understand is if I do this immediately after :- pIDBInitialize->Release(); I don't see a dll module unload, so that SSCE20.dll (and friends) are still loaded into my process. Now I tried CoFreeUnusedLibraries() which I figure forces COM to purge any unused libraries, but it doesn't seem to do the trick. At runtime I want to be able to completely unload the SQLServerCE 2.0 dll from the process to streamline an upgrade to 3.5SP1. I suspect this has something to do with the shared dll model that Microsoft use under WindowsCE... but, I might be wrong :) Thanks in advance, David.

• checkins/recent not returning comments or even counts of comments

  - by Gilbert

  My application has been using the checkins/recent endpoint to show where all the current users friends are currently at and I had included a button the user could press to comment on a checkin. The button used to have the comment count on it until recently. It seems the checkins/recent endpoint no longer returns comments or even a comment count for those checkins. I would have to query each checkin in order to get the comment count which adds to the data usage not to mention API usage counts. Is there another way to do this that I'm not seeing? Could you please at least put the comment count back? You have the photo information, why not comments? Thanks

• Can the opensocial API remotely search for users in orkut etc.?

  - by Martin

  Does anyone know if (and how) I can build an application (Java/Ruby/whatever) doing REST or RPC calls to a social network like Orkut (using opensocial) to search for a user by name or email address? So far I know that I can list all friends for a particular user ID, but I want to search among all users. Would I need to code it as an app/gadget running inside the google sandbox or is there a way to get a list of matching user ID via REST? So far I got this one to work: http://code.google.com/p/opensocial-ruby-client/wiki/GettingStarted. But with this API and the gadget linked there I only get people that are already linked to me... Thanks for answers, Martin
