  • Read -> change -> save. Thread safe.

    - by Pavel Alexeev
    This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.

I have the following code: Contact newContact = new Contact(); When I let the code run without any breakpoints, I get a NullReferenceException on all of the properties of this object. However, if I put a breakpoint just after this line, I can see all of the properties have been initialises and the rest of my code executes fine. Any idea's would be greatly appreciated

  • GQL Request BadArgument Error. How to get around with my case?

    - by awegawef
    My query is essentially the following: entries=Entry.all().order("-votes").order("-date").filter("votes >", VOTE_FILTER).fetch(PAGE_SIZE+1, page* PAGE_SIZE) I want to grab N of the latest entries that have a voting score above some benchmark (VOTE_FILTER). Google currently says that I cannot filter on 'votes' because I order by 'date.' I don't see a way that I can do this the way I want to, so I'd appreciate any advice.

  • Localized Android app without using "res" folder. Is there a downside?

    - by user312916
    I am developing a game with Unity 3D and want to use custom code to get strings in the various languages I will be supporting. I've read articles about using the Android "res/values-xx/" directories (such as this page: http://developer.android.com/training/basics/supporting-devices/languages.html). If I do not store my translated strings in this way is there a downside? My main concern is whether the Google Play store may not know what languages my app is localized for.

  • Authentication mechanism comparison

    - by Heavy Bytes
    I have to start a new project where user authentication/management will be required. A lot of websites use existing authentication mechanisms like facebook/twitter/openID/google/etc (even SO). While I might understand that they are used to simplify some parts of this workflow can someone enumerate the pluses and minuses of using one of these authentication mechanisms vs. an usual user creation and what should I look for when I do this? Thanks in advance!
