• Google Analytics - Goals - Advanced Segments - Does it keep cookies for tracking visitors?

  - by Kuko

  Hi there, I am working with Google Analytics - Goals and Funnels for quite sometime, but one thing is is not clear for me. I would very much appreciate if you could help me. We are advertising on several sites rotating several different ads. Our main goal is to collect as many sign-ups (new users) as possible for as low price as possible. We use to advertise the way, that each ad has the same URL where to land, but contains different parameter (e.g. http://www.brautpunkt.de/?ref=fb01 or ..... .de/?ref=adw03). My question is: If I am looking at the goals (Goals Overview), filtering it through Advanced Segments (Landing Page contains /?ref=fb01) is this subset of goals done only by the users who registered in the same session after they came on our site directly from the ad? or also by those users who came first time through this ad (/?ref=fb01), didn't register in the same session but came directly for example on the other day and register than? Thank you very much in advance for your advice. Peter

• How to check if two records have a self-referencing relation?

  - by Machine

  Consider the following schema with users and their collegues (friends): Users User: columns: user_id: name: user_id as userId type: integer(8) unsigned: 1 primary: true autoincrement: true first_name: name: first_name as firstName type: string(45) notnull: true last_name: name: last_name as lastName type: string(45) notnull: true email: type: string(45) notnull: true unique: true relations: Collegues: class: User local: invitor foreign: invitee refClass: CollegueStatus equal: true onDelete: CASCADE onUpdate: CASCADE Join table: CollegueStatus: columns: invitor: type: integer(8) unsigned: 1 primary: true invitee: type: integer(8) unsigned: 1 primary: true status: type: enum(8) values: [pending, accepted, denied] default: pending notnull: true Now, let's say I two records, one for the user making a HTTP request (the logged in user), and one record for a user he wants to send a message to. I want to check if these users are collegues. Questions: Does Doctrine have any pre-build functionality to check if two records with with self-relations are related? If not, how would you write a method to check this? Where would you put said method? (In the User-class, UserTable-class etc) I could probably do something like this: public function (User $user1, User $user2) { // Ensure we load collegues if $user1 was fetched with DQL that // doesn't load this relation $collegues = $user1->get('Collegues'); $areCollegues = false; foreach($collegues as $collegue) { if($collegue['userId'] === $user2['userId']) { $areCollegues = true; break; } } return $areCollegues; } But this looks a neither efficient nor pretty. I just feel that it should be solved already for self-referencing relations to be nice to use.

• How to redirect page

  - by sharun

  Hi i created one java application in which i tried to open my company's standard login page and i planned to redirect the link to open my own design page. Standard login page is displayed, instead of going to my own design page as usual its going to mail page. After sign out the mail page i'm gettting my own design page. But my need is, when i sign in the standard login page it should diplay my own design page. Is it possible? Please Help me. And this is code that i followed import java.io.IOException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.google.appengine.api.users.UserService; import com.google.appengine.api.users.UserServiceFactory; import com.google.appengine.api.users.User; public class New extends HttpServlet { /** * */ private static final long serialVersionUID = 1L; public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); resp.setContentType("text/html"); UserService userService = UserServiceFactory.getUserService(); User user = userService.getCurrentUser(); if (user != null) { if(user.getEmail().equals("[email protected]")) { resp.getWriter().println("done"); resp.sendRedirect("/login.jsp"); } else { resp.getWriter().println("Hello, " + user.getNickname()+"<br>"); resp.getWriter().println("Thanks for your interest.

• Where should I store shared resources between LocalSystem and regular user with UAC?

  - by rwired

  My application consists of two parts: A Windows Service running under the LocalSystem account and a client process running under the currently logged in regular user. I need to deploy the application across Windows versions from XP up to Win7. The client will retrieve files from the web and collect user data from the user. The service will construct files and data of it's own which the client needs to read. I'm trying to figure out the best place (registry or filesystem, or mix) to store all this. One file the client or service needs to be able to retrieve from the net is an update_patch executable which needs to run whenever an upgrade is available. I need to be sure the initial installer SETUP.EXE, and also the update_patch can figure out this ideal location and set a RegKey to be read later by both client and server telling them the magic location (The SETUP.EXE will run with elevated privileges since it needs to install the service) On my Win7 test system the service %APPDATA% points to: C:\Windows\system32\config\systemprofile\AppData\Roaming and the %APPDATA% of the client points to: C:\Users\(username)\AppData\Roaming Interestingly Google Chrome stores everything (App and Data) in C:\Users\(username)\AppData\Local\Google\Chrome Chrome runs pretty much in exactly the way I want my suite to run (able to silently update itself in the background) What I'm trying to avoid is nasty popups warning the user that the app wants to modify the system, and I want to avoid problems when VirtualStore doesn't exist because the user is running XP/2000/2003 or has UAC turned off. My target audience are non-tech-savvy general Windows users.

• Modify the server side functions using jquery

  - by ant

  Hi, I am developing one website using cakephp and jquery technologies. Server-side there are some functions which handles sql queris. As per requirement I want to modify server side functions on client side using jquery AJAX call. E.g. : Below is the function on server side to modify users information. function modifyUser(username,userid) { //update query statements } Then jquery AJAX call will be like this : $.ajax({ url: 'users/modiyUser', success: function() { alert("Updation done") or any statements. } }); and I want to modify above i.e. server side function depending upon client input criteria. $.ajax({ function users/modiyUser(username,userid) { // I will write here any other statements which gives me some other output. } }); Above AJAX call syntax may not present, but i think you all understood what I am trying to do I simply wants to modify/override server side functions on client side. Please let me know is there any way to resolve above mentioned requirement. Thanks in adavance

• Help needed setting up nginx to serve static files.

  - by Catalina

  Hi Guys, I'm trying to setup nginx to serve static files. Basically all I need is to have http://mydomain.com/site_media/ point to /var/django/myproject/site_media. I have tried so many configurations and when I test it I always get a 404 error for static files. Can anyone please tell me what I'm doing wrong or how I should be setting this up?

• Including partial views when applying the Mode-View-ViewModel design pattern

  - by Filip Ekberg

  Consider that I have an application that just handles Messages and Users I want my Window to have a common Menu and an area where the current View is displayed. I can only work with either Messages or Users so I cannot work simultaniously with both Views. Therefore I have the following Controls MessageView.xaml UserView.xaml Just to make it a bit easier, both the Message Model and the User Model looks like this: Name Description Now, I have the following three ViewModels: MainWindowViewModel UsersViewModel MessagesViewModel The UsersViewModel and the MessagesViewModel both just fetch an ObserverableCollection<T> of its regarding Model which is bound in the corresponding View like this: <DataGrid ItemSource="{Binding ModelCollection}" /> The MainWindowViewModel hooks up two different Commands that have implemented ICommand that looks something like the following: public class ShowMessagesCommand : ICommand { private ViewModelBase ViewModel { get; set; } public ShowMessagesCommand (ViewModelBase viewModel) { ViewModel = viewModel; } public void Execute(object parameter) { var viewModel = new ProductsViewModel(); ViewModel.PartialViewModel = new MessageView { DataContext = viewModel }; } public bool CanExecute(object parameter) { return true; } public event EventHandler CanExecuteChanged; } And there is another one a like it that will show Users. Now this introduced ViewModelBase which only holds the following: public UIElement PartialViewModel { get { return (UIElement)GetValue(PartialViewModelProperty); } set { SetValue(PartialViewModelProperty, value); } } public static readonly DependencyProperty PartialViewModelProperty = DependencyProperty.Register("PartialViewModel", typeof(UIElement), typeof(ViewModelBase), new UIPropertyMetadata(null)); This dependency property is used in the MainWindow.xaml to display the User Control dynamicly like this: <UserControl Content="{Binding PartialViewModel}" /> There are also two buttons on this Window that fires the Commands: ShowMessagesCommand ShowUsersCommand And when these are fired, the UserControl changes because PartialViewModel is a dependency property. I want to know if this is bad practice? Should I not inject the User Control like this? Is there another "better" alternative that corresponds better with the design pattern? Or is this a nice way of including partial views?

• Relational MySQL - fetched properties?

  - by Kelso.b

  I'm currently using the following PHP code: // Get all subordinates $subords = array(); $supervisorID = $this->session->userdata('supervisor_id'); $result = $this->db->query(sprintf("SELECT * FROM users WHERE supervisor_id=%d AND id!=%d",$supervisorID, $supervisorID)); $user_list_query = 'user_id='.$supervisorID; foreach($result->result() as $user){ $user_list_query .= ' OR user_id='.$user->id; $subords[$user->id] = $user; } // Get Submissions $submissionsResult = $this->db->query(sprintf("SELECT * FROM submissions WHERE %s", $user_list_query)); $submissions = array(); foreach($submissionsResult->result() as $submission){ $entriesResult = $this->db->query(sprintf("SELECT * FROM submittedentries WHERE timestamp=%d", $submission->timestamp)); $entries = array(); foreach($entriesResult->result() as $entries) $entries[] = $entry; $submissions[] = array( 'user' => $subords[$submission->user_id], 'entries' => $entries ); $entriesResult->free_result(); } Basically I'm getting a list of users that are subordinates of a given supervisor_id (every user entry has a supervisor_id field), then grabbing entries belonging to any of those users. I can't help but think there is a more elegant way of doing this, like SELECT FROM tablename where user->supervisor_id=2222 Is there something like this with PHP/MySQL? Should probably learn relational databases properly sometime. :(

• What online sites are available to help organize redundant error/cron emails?

  - by xyld

  I feel like I saw a site somewhere that would "dedupe" error messages commonly sent from frameworks like Django or cron errors. I cannot seem to re-find the site however. Have people heard of online tools like this that help wade through the hundreds of emails applications can possibly send at times?

• Handling Types Defined in Plug-ins That Are No Longer Available

  - by Chris

  I am developing a .NET framework application that allows users to maintain and save "projects". A project can consist of components whose types are defined in the assemblies of the framework itself and/or in third-party assemblies that will be made available to the framework via a yet-to-be-built plug-in architecture. When a project is saved, it is simply binary-serialised to file. Projects are portable, so multiple users can load the same project into their own instances of the framework (just as different users may open the same MSWord document in their own local copies of MSWord). What's more, the plug-ins available to one user's framework might not be available to that of another. I need some way of ensuring that when a user attempts to open (i.e. deserialise) a project that includes a type whose defining assembly cannot be found (either because of a framework version incompatibility or the absence of a plug-in), the project still opens but the offending type is somehow substituted or omitted. Trouble is, the research I've done to date does not even hint at a suitable approach. Any ideas would be much appreciated, thanks.

• Event feed implementation - will it scale?

  - by SlappyTheFish

  Situation: I am currently designing a feed system for a social website whereby each user has a feed of their friends' activities. I have two possible methods how to generate the feeds and I would like to ask which is best in terms of ability to scale. Events from all users are collected in one central database table, event_log. Users are paired as friends in the table friends. The RDBMS we are using is MySQL. Standard method: When a user requests their feed page, the system generates the feed by inner joining event_log with friends. The result is then cached and set to timeout after 5 minutes. Scaling is achieved by varying this timeout. Hypothesised method: A task runs in the background and for each new, unprocessed item in event_log, it creates entries in the database table user_feed pairing that event with all of the users who are friends with the user who initiated the event. One table row pairs one event with one user. The problems with the standard method are well known – what if a lot of people's caches expire at the same time? The solution also does not scale well – the brief is for feeds to update as close to real-time as possible The hypothesised solution in my eyes seems much better; all processing is done offline so no user waits for a page to generate and there are no joins so database tables can be sharded across physical machines. However, if a user has 100,000 friends and creates 20 events in one session, then that results in inserting 2,000,000 rows into the database. Question: The question boils down to two points: Is this worst-case scenario mentioned above problematic, i.e. does table size have an impact on MySQL performance and are there any issues with this mass inserting of data for each event? Is there anything else I have missed?

• Getting random record from database with group by

  - by Saif Bechan

  Hello i have a question on picking random entries from a database. I have 4 tables, products, bids and autobids, and users. Products ------- id 20,21,22,23,24(prime_key) price........... etc........... users ------- id(prim_key) name user1,user2,user3 etc bids ------- product_id user_id created autobids -------- user_id product_id Now a multiple users can have an autobid on an product. So for the next bidder I want to select a random user from the autobid table example of the query in language: for each product in the autobid table I want a random user, which is not the last bidder. On product 20 has user1,user2,user3 an autobidding. On product 21 has user1,user2,user3 an autobidding Then I want a resultset that looks for example like this 20 – user2 21 – user3 Just a random user. I tried miximg the GOUP BY (product_id) and making it RAND(), but I just can't get the right values from it. Now I am getting a random user, but all the values that go with it don't match. Can someone please help me construct this query, I am using php and mysql

• Advice, pls: web app stack suitable for shared hosting ...

  Considerations: greatly prefer Python want to build as little as possible myself (I suppose this is obvious) prefer built-in or availability of add-on wiki and conferencing (nothing fancy) need three levels of authentication: single 'super user', one administration user for each of several groups, individual 'ordinary' users authenticate to one of these groups cron substitute à la Django or Zope would be nice, for keeping an RSS feed up-to-date, principally hosting I use does not provide mod_wsgi, mod_python, etc. Your thoughts, please.

• SQLAlchemy & Complex Queries

  - by user356594

  I have to implement ACL for an existing application. So I added the a user, group and groupmembers table to the database. I defined a ManyToMany relationship between user and group via the association table groupmembers. In order to protect some ressources of the app (i..e item) I added a additional association table auth_items which should be used as an association table for the ManyToMany relationship between groups/users and the specific item. item has following columns: user_id -- user table group_id -- group table item_id -- item table at least on of user_id and group_id columns are set. So it's possible to define access for a group or for a user to a specific item. I have used the AssociationProxy to define the relationship between users/groups and items. I now want to display all items which the user has access to and I have a really hard time doing that. Following criteria are used: All items which are owned by the user should be shown (item.owner_id = user.id) All public items should be shown (item.access = public) All items which the user has access to should be shown (auth_item.user_id = user.id) All items which the group of the user has access to should be shown. The first two criteria are quite straightforward, but I have a hard time doing the 3rd one. Here is my approach: clause = and_(item.access == 'public') if user is not None: clause = or_(clause,item.owner == user,item.users.contains(user),item.groups.contains(group for group in user.groups)) The third criteria produces an error. item.groups.contains(group for group in user.groups) I am actually not sure if this is a good approach at all. What is the best approach when filtering manytomany relationships? How I can filter a manytomany relationship based on another list/relationship? Btw I am using the latest sqlalchemy (6.0) and elixir version Thanks for any insights.

• MySQL - Structure for Permissions to Objects

  - by Kerry

  What would be an ideal structure for users permissions of objects. I've seen many related posts for general permissions, or what sections a user can access, which consists of a users, userGroups and userGroupRelations or something of that nature. In my system there are many different objects that can get created, and each one has to be able to be turned on or off. For instance, take a password manager that has groups and sub groups. Group 1 Group 2 Group 3 Group 4 Group 5 Group 6 Group 7 Group 8 Group 9 Group 10 Each group can contain a set of passwords. A user can be given read, write, edit and delete permissions to any group. More groups can get created at any point in time. If someone has permission to a group, I should be able to make him have permissions to all sub groups OR restrict it to just that group. My current thought is to have a users table, and then a permissions table with columns like: permission_id (int) PRIMARY_KEY user_id (int) INDEX object_id (int) INDEX type (varchar) INDEX read (bool) write (bool) edit (bool) delete (bool) This has worked in the past, but the new system I'm building needs to be able to scale rapidly, and I am unsure if this is the best structure. It also makes the idea of having someone with all subgroup permissions of a group more difficult. So, as a question, should I use the above structure? Or can someone point me in the direction of a better one?

• How to deal with forward declaration / #import in Cocoa Touch (Objective-C cross C++) correctly?

  I am trying to write this header file: //@class AQPlayer; //#import "AQPlayer.h" @interface AQ_PWN_iPhoneViewController : UIViewController { AQPlayer* player; } @end AQPlayer is a .mm file written in C++. I tried to make a class forward declaration here, but it complains to me: error: cannot find interface declaration for 'AQPlayer' So I tried to "#import" the header file instead, but it complains something completely off and weird.

• Sorting and Pagination does not work after I build a custom keyword search that is build using relat

  - by Roland

  I recently started to build a custom keyword search using Yii 1.1.x The search works 100%. But as soon as I sort the columns and use pagination in the admin view the search gets lost and all results are shown. So with otherwords it's not filtering so that only the search results show. Somehow it resets it. In my controller my code looks as follows $builder=Messages::model()->getCommandBuilder(); //Table1 Columns $columns1=array('0'=>'id','1'=>'to','2'=>'from','3'=>'message','4'=>'error_code','5'=>'date_send'); //Table 2 Columns $columns2=array('0'=>'username'); //building the Keywords $keywords = explode(' ',$_REQUEST['search']); $count=0; foreach($keywords as $key){ $kw[$count]=$key; ++$count; } $keywords=$kw; $condition1=$builder->createSearchCondition(Messages::model()->tableName(),$columns1,$keywords,$prefix='t.'); $condition2=$builder->createSearchCondition(Users::model()->tableName(),$columns2,$keywords); $condition = substr($condition1,0,-1) .

• How to structure the tables of a very simple blog in MySQL?

  - by Programmer

  I want to add a very simple blog feature on one of my existing LAMP sites. It would be tied to a user's existing profile, and they would be able to simply input a title and a body for each post in their blog, and the date would be automatically set upon submission. They would be allowed to edit and delete any blog post and title at any time. The blog would be displayed from most recent to oldest, perhaps 20 posts to a page, with proper pagination above that. Other users would be able to leave comments on each post, which the blog owner would be allowed to delete, but not pre-moderate. That's basically it. Like I said, very simple. How should I structure the MySQL tables for this? I'm assuming that since there will be blog posts and comments, I would need a separate table for each, is that correct? But then what columns would I need in each table, what data structures should I use, and how should I link the two tables together (e.g. any foreign keys)? I could not find any tutorials for something like this, and what I'm looking to do is really offer my users the simplest version of a blog possible. No tags, no moderation, no images, no fancy formatting, etc. Just a simple diary-type, pure-text blog with commenting by other users.

• Zend hostname route doesn't match when it has child routes

  - by talisker

  I am implementing an Admin module, which contains the following routes: 'router' => array( 'routes' => array( 'admin' => array( 'type' => 'Zend\Mvc\Router\Http\Hostname', 'options' => array( 'route' => ':subdomain.mydomain.local', 'constraints' => array( 'subdomain' => 'admin', ), 'defaults' => array( 'module' => '__NAMESPACE__', 'controller' => 'Admin\Controller\Index', 'action' => 'index', ), ), 'priority' => 9000, 'may_terminate' => true, 'child_routes' => array( 'users' => array( 'type' => 'Zend\Mvc\Router\Http\Literal', 'options' => array( 'route' => '/users', 'defaults' => array( 'module' => '__NAMESPACE__', 'controller' => 'Admin\Controller\Users', 'action' => 'index', ), ), ), ) ), ), ), And this is the home route configuration: 'home' => array( 'type' => 'Zend\Mvc\Router\Http\Literal', 'options' => array( 'route' => '/', 'defaults' => array( 'controller' => 'Application\Controller\Index', 'action' => 'index', ), ), ), When I try to access to http://admin.mydomain.com, the route match always with the homeroute, but if I remove all the child routes from the admin route, the behavior is correct and a http://admin.mydomain.com matches with the adminroute. Any idea?

• Improving performance in this query

  - by Luiz Gustavo F. Gama

  I have 3 tables with user logins: sis_login = administrators tb_rb_estrutura = coordinators tb_usuario = clients I created a VIEW to unite all these users by separating them by levels, as follows: create view `login_names` as select `n1`.`cod_login` as `id`, '1' as `level`, `n1`.`nom_user` as `name` from `dados`.`sis_login` `n1` union all select `n2`.`id` as `id`, '2' as `level`, `n2`.`nom_funcionario` as `name` from `tb_rb_estrutura` `n2` union all select `n3`.`cod_usuario` as `id`, '3' as `level`, `n3`.`dsc_nome` as `name` from `tb_usuario` `n3`; So, can occur up to three ids repeated for different users, which is why I separated by levels. This VIEW is just to return me user name, according to his id and level. considering it has about 500,000 registered users, this view takes about 1 second to load. too much time, but is becomes very small when I need to return the latest posts on the forum of my website. The tables of the forums return the user id and level, then look for a name in this VIEW. I have registered 18 forums. When I run the query, it takes one second for each forum = 18 seconds. OMG.

• Seeding many to many tables with Entity Framework

  - by Doozer1979

  I have a meeting entity and a users entity which have a many to many relationship. I'm using Autopoco to create seed data for the Users and meetings How do i seed the UserMeetings linking table that is created by EntityFramework with seed data? The linking table has two fields in it; User_Id, and Meeting_ID. I'm looping through the list of users that autopoco creates and attaching a random number of meetings Here's what i've got so far. foreach (var user in userList) { var rand = new Random(); var amountOfMeetingsToAdd = rand.Next(1, 300); for (var i = 0; i <= amountOfMeetingsToAdd; i++) { var randomMeeting = rand.Next(1, MeetingRecords); //Error occurs on This line user.Meetings.Add(_meetings[randomMeeting]); } } I got an 'Object reference not set to an instance of an object.' even though the meeting record that i'm trying to attach does exist. For info all this is happening prior to me saving the context to the DB.

• Zend Framework - counting rows in select clause ?

  - by moogeek

  Hello! I'm investigating Zend Framework and currently stucked in counting resulting rows of sql query... Every method I try (from documentation and some blogposts and tutorials) returns an error (like Call to undefined function) or simply gives the incorrect value. I've tried this: $checkquery = $db->select() ->from('users', 'COUNT(*)') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=fetchRow($checkquery)->num; ...then this one: $checkquery = $db->select() ->from('users', '*') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=count($checkquery->fetchAll()); and even: $checkquery = $db->select() ->from('users', '*') ->where('login = ?', $login) ->where('password = ?', $password) ->query(); $checkrequest=$checkquery->fetchAll()->num; Also rowCount() and count(fetchRow()) and count(fetchAll()->toArray()). But always I got an error message or duplicate inserts in db in further insert function. So what is the correct way to do the resulting row calculation in select clause in Zend Framework 1.9 (I use this one) ?

• How can I cluster short messages [Tweets] based on topic ? [Topic Based Clustering]

  - by Jagira

  Hello, I am planning an application which will make clusters of short messages/tweets based on topics. The number of topics will be limited like Sports [ NBA, NFL, Cricket, Soccer ], Entertainment [ movies, music ] and so on... I can think of two approaches to this Ask for users to tag questions like Stackoverflow does. Users can select tags from a predefined list of tags. Then on server side I will cluster them on based of tags. Pros:- Simple design. Less complexity in code. Cons:- Choices for users will be restricted. Clusters will not be dynamic. If a new event occurs, the predefined tags will miss it. Take the message, delete the stopwords [ predefined in a dictionary ] and apply some clustering algorithm to make a cluster and depending on its popularity, display the cluster. The cluster will be maintained according to its sustained popularity. New messages will be skimmed and assigned to corresponding clusters. Pros:- Dynamic clustering based on the popularity of the event/accident. Cons:- Increased complexity. More server resources required. I would like to know whether there are any other approaches to this problem. Or are there any ways of improving the above mentioned methods? Also suggest some good clustering algorithms.I think "K-Nearest Clustering" algorithm is apt for this situation.
