  • What groupware/collaboration system to choose?

    - by Ivan
    I am looking for a good (stable enough, intuitive enough, and the more technologically modern and advanced - the better) free PHP-based online groupware/collaboration system. 100% UTF-8 is a requirement. OOP-style code is an advantage. And collaborative mindmapping would be a cool feature to have. The team is of ~20 people. Any suggestions?

  • Bug Repository

    - by goldenmean
    Hello, Is there any opensource or public domain repository of bugs where one can see the various bugs, symptoms of those bugs, and their fixes.

  • Given year, month and day, all in int, how would I generate an NSDate

    - by BU
    I think the solution is really simple, I just haven't come across it online. Suppose I am given int year, int month, int day, int hour, int min, int sec.. how do I generate NSDate out of it? I know we can use [NSDate initWithString:] but I think it gets complicated if month/day/hour/min/sec are one digit numbers. Thanks in advance for your help.

  • Fluent NHibernate caching with automapping

    - by md1337
    I'm trying to understand how to configure Fluent NHibernate to enable 2nd-level caching for queries, entities, etc... There is very little information online on how to do that. I see it can be achieved by manually mapping the entities but I don't want that. I want to be able to cache all entities and not address the classes individually. How can I do that? Thanks.

  • Receiving data with Winsock

    - by Tamir
    Right now, I'm programming the networking for my online game, and I'm not really sure what to do about receiving data. The problem is that I can't really guess the packet's size, so I thought of reading just 4 bytes from the packet and converting them to an int to know what's the packet's size. Then I'll just create a buffer in that size and receive the rest of the packet, is that a good idea? For your information, I'm using non-blocking i/o.

  • Why use "foo" in coding examples? [closed]

    - by ThePower
    Possible Duplicates: To foo bar, or not to foo bar: that is the question. Bit of a general question here, but it's something I would like to know! Whenever I am looking for resolutions to my C# problems online, I always come across "foo" being used as an example. Does this represent anything or is it just one of those unexplained catchy object names, used by many people in examples?

  • AJAX Web Application Design

    - by Colonel Sponsz
    I'm working on a personal project to build a small web app that is built using AJAX requests and talks to a RESTful API rather than traditional HTML pages and form submissions. Are there any online articles or tutorials or any books that people could recommend that cover design patterns for this kind of thing?

  • Where can you find fun/educational programming challenges?

    - by tj9991
    I've searched around for different challenge sites, and most of them seem to be geared towards difficulty in problem solving logically, rather than trying to use your language of choice to do something you haven't used it for. Their center is around mathematics rather than function design. Some kind of point system for correctly solving challenges, or solving them the most efficient/smallest would be neat as well.

  • Treebeard admin in Django

    - by Sharath
    I've setup Treebeard in Django and everything seems to have gone well. I tried to setup the admin system and I can see my models being presented in the admin interface. However, when I try to add new data using the admin interface, I get the following error in my template. The code still works fine, and I did a check in my DB and the data seems to be inserted properly. However, the view doesn't seem to load properly. Any idea about what is causing this?? The exception am getting is.. Caught an exception while rendering: Failed lookup for key [request] in u'[{\'action_index\': 0, \'block\': , , , , , , ]}, {\'block\': , , , ], , , , , \n \', ], , ], , , , ], , , \n \', , , , , , , , , ], , ], \n \']}, {\'cl\': , \'root_path\': None, \'actions_on_bottom\': False, \'title\': u\'Select album to change\', \'has_add_permission\': True, \'media\': , \'is_popup\': False, \'action_form\': , \'actions_on_top\': True, \'app_label\': \'gallery\'}, {\'MEDIA_URL\': \'\'}, {\'LANGUAGES\': ((\'ar\', \'Arabic\'), (\'bn\', \'Bengali\'), (\'bg\', \'Bulgarian\'), (\'ca\', \'Catalan\'), (\'cs\', \'Czech\'), (\'cy\', \'Welsh\'), (\'da\', \'Danish\'), (\'de\', \'German\'), (\'el\', \'Greek\'), (\'en\', \'English\'), (\'es\', \'Spanish\'), (\'et\', \'Estonian\'), (\'es-ar\', \'Argentinean Spanish\'), (\'eu\', \'Basque\'), (\'fa\', \'Persian\'), (\'fi\', \'Finnish\'), (\'fr\', \'French\'), (\'ga\', \'Irish\'), (\'gl\', \'Galician\'), (\'hu\', \'Hungarian\'), (\'he\', \'Hebrew\'), (\'hi\', \'Hindi\'), (\'hr\', \'Croatian\'), (\'is\', \'Icelandic\'), (\'it\', \'Italian\'), (\'ja\', \'Japanese\'), (\'ka\', \'Georgian\'), (\'ko\', \'Korean\'), (\'km\', \'Khmer\'), (\'kn\', \'Kannada\'), (\'lv\', \'Latvian\'), (\'lt\', \'Lithuanian\'), (\'mk\', \'Macedonian\'), (\'nl\', \'Dutch\'), (\'no\', \'Norwegian\'), (\'pl\', \'Polish\'), (\'pt\', \'Portuguese\'), (\'pt-br\', \'Brazilian Portuguese\'), (\'ro\', \'Romanian\'), (\'ru\', \'Russian\'), (\'sk\', \'Slovak\'), (\'sl\', \'Slovenian\'), (\'sr\', \'Serbian\'), (\'sv\', \'Swedish\'), (\'ta\', \'Tamil\'), (\'te\', \'Telugu\'), (\'th\', \'Thai\'), (\'tr\', \'Turkish\'), (\'uk\', \'Ukrainian\'), (\'zh-cn\', \'Simplified Chinese\'), (\'zh-tw\', \'Traditional Chinese\')), \'LANGUAGE_BIDI\': False, \'LANGUAGE_CODE\': \'en-us\'}, {}, {\'perms\': , \'messages\': [], \'user\': }, {}]' This happens after I hit the save button in Django admin.

  • getView() (for a Custom ListView ) doesn't get called on notifyDatasetChanged()

    - by hungson175
    Hi everyone, I have the following problem, and searched for a while but haven't got any solution from the net: I have a custom list view, each item has the following layout (I just post the essential): <LinearLayout> <ImageView android:id="@+id/friendlist_iv_avatar" /> <TextView andorid:id="@+id/friendlist_tv_nick_name" /> <ImageView android:id="@+id/friendlist_iv_status_icon" /> </LinearLayout> And I have a class FriendRowItem, which is inflated from the above layout: public class FriendRowItem extends LinearLayout{ private ImageView ivAvatar; private ImageView ivStatusIcon; private TextView tvNickName; public FriendRowItem(Context context) { super(context); RelativeLayout friendRow = (RelativeLayout) Helpers.inflate(context, R.layout.friendlist_row); this.addView(friendRow); ivAvatar = (ImageView)findViewById(R.id.friendlist_iv_avatar); ivStatusIcon = (ImageView)findViewById(R.id.friendlist_iv_status_icon); tvNickName = (TextView)findViewById(R.id.friendlist_tv_nick_name); } public void setPropeties(Friend friend) { //Avatar ivAvatar.setImageResource(friend.getAvatar().getDrawableResourceId()); //Status Status.Type status = friend.getStatusType(); if ( status == Type.ONLINE) { ivStatusIcon.setImageResource(R.drawable.online_icon); } else { ivStatusIcon.setImageResource(R.drawable.offline_icon); } //Nickname String name = friend.getChatID(); if ( friend.hasName()) { name = friend.getName(); } tvNickName.setText(name); } } In the main activity, I have a custom listview: lvMainListView, with an custom adapter (whose class extends ArrayAdapter - and off course: override the method getView ), the data set of the adapter is: ArrayList<Friend> friends: private class FriendRowAdapter extends ArrayAdapter<Friend> { public FriendRowAdapter(Context applicationContext, int friendlistRow, ArrayList<Friend> friends) { super(applicationContext, friendlistRow, friends); } @Override public View getView(int position,View convertView,ViewGroup parent) { Friend friend = getItem(position); FriendRowItem row = (FriendRowItem) convertView; if ( row == null ) { row = new FriendRowItem(ShowFriendsList.this.getApplicationContext()); } row.setPropeties( friend ); return row; } } the problem is when I change the status of a friend from OFFLINE to ONLINE, then call notifyDataSetChanged(), nothing happens : the status icon of that friend doesn't change. I tried debugging, and saw the code: notifyDataSetChanged() get called, but the custom getView() is not fired ! Can you please tell me, that is normal in Android, or did I do something wrong ? (I am using Android 1.5). Thank you in advance, Son
