• iPhone: Switching from a map screen to a battle screen without the map progress being reset

  - by user298261

  Hello! I'm trying to make a role-playing game, and I want the game to work so that it transitions to the battle NIB for battles, then returns back to the map NIB afterward, yet still retain all the progress the player has made exploring the dungeon. I've tried proto-typing this with just a view-switcher, where one view creates content, and then switches to the other view, and then coming back from the other view. However, once the view goes back to the original, the original view is reset. How to make the data persistent so that it doesn't reset after every "battle"? Thanks!

• How to compile and build C# projects with Ant and Mono?

  - by Wing C. Chen

  I am currently working on a project with both java and C# codes within. Java takes the major role in this project. However, C# still takes a small part in it. I am using Ant to build the projects, and would very much like to use it to build C# too. I have learned that it's possible to build C# under Ant with the help of Mono. Can anybody provide any link of tutorial or guidance here? I was trying to google for it. But I haven't found any comprehensive data.

• How to increase wifi speed for laptops

  - by sagar

  Now, Let me explain the situation. I am having a query regarding Wi-Fi network. I am having PC & laptop. I requested my Wi-Fi providers that I want connection in my PC. So that - Wi-Fi provider set up an Antenna on my building Terrace - They joined a cable to pc & that Antenna. ( I think using RJ45 connector ) - The reason behind this - my does not have a built in Wi-Fi adapter. Now - almost laptops have built in Wi-Fi. Now - On terrace there is Wi-Fi with superb speed. But on my flat - Wi-fi comes with low speed. So, when ever I use internet on my pc - it has great speed - but my laptop works with low speed. The reason behind this - PC is catching wifi from terrace & laptop is catching the wifi from it's own place. Now, My question is something like this. Can we place an antenna or something like that & connect it to laptop for better wifi speed? ( I am not technical person - Please add comment for down vote - if any ) ( Please add comment for more explanation of my Problem ) Thanks in advance for sharing your knowledge. Sagar

• Giving Zend Navigation Pages Multiple ACL Privileges

  - by Sonny

  I'm using Zend_Navigation and am trying to integrate it with Zend_Acl. Each page in the navigation has a privilege attribute. What I can't determine is how to define multiple privileges for a single page. Use case: A page that is for managing users. I want to display that page (in navigation) if the current signed in user's role has add, edit, or delete privileges on the Users resource. Example entry in the navigation XML: <admin_users> <label>Users</label> <route>default</route> <controller>admin</controller> <action>users</action> <resource>Users</resource> <privilege>add,edit,delete</privilege> </admin_users> Using a comma-separated list as above doesn't lend the desired behavior.

• MembershipProvider, IPrincipal, IIdentity?

  - by MRFerocius

  Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

• Active Directory LDAP and user issues (using apache2 for svn access)

  - by CaCl

  I currently have a setup where I work that lets users use their active directory domain logins and passwords to authenticate and authorize access to Subversion. Currently I need to allow application accounts the same access. So our IT group creates application accounts in the active directory for us to use. But they want to be "secure" so they set the "Workstations Allowed" to be only a limited number of workstations. So when an application account hits the apache2 server for authentication they can't login for some reason and I'm having a heck of a time trying to debug. The error logs only show me: [Tue Apr 06 11:24:25 2010] [warn] [client 24.24.24.24] [3469] auth_ldap authenticate: user appuser13 authentication failed; URI /svn [ldap_simple_bind_s() to check user credentials failed][Invalid credentials] [Tue Apr 06 11:24:25 2010] [error] [client 24.24.24.24] user appuser13: authentication failure for "/svn": Password Mismatch I've checked the password numerous times and it appears to be correct but I can't seem to get the user to authenticate properly. Below is a snippet of the apache configuration for ldap: # Auth providers # Active Directory <AuthnProviderAlias ldap ldap1> AuthBasicProvider ldap AuthLDAPURL "ldap://dmain.company.com:389/dc=dmain,dc=company,dc=com?sAMAccountName?sub?(objectClass=*)" AuthLDAPBindDN "CN=svnuser13,OU=Application Accounts,dc=dmain,dc=teradata,dc=com" AuthLDAPBindPassword secret3 </AuthnProviderAlias> # Another set of users from a different group <AuthnProviderAlias ldap ldap2> AuthBasicProvider ldap AuthLDAPURL ldap://diffldapserver:389/dc=specialusers,dc=com?uid </AuthnProviderAlias> # Another set of users from a different group <AuthnProviderAlias file file1> AuthUserFile /var/svn/auth/htpasswd </AuthnProviderAlias> <Location /svn> DAV svn SVNPath /var/svn Satisfy Any Require valid-user AuthType Basic AuthName "SVN Repository" AuthBasicProvider ldap1 file1 ldap2 AuthzSVNAccessFile /var/svn/auth/access AuthzLDAPAuthoritative on Require valid-user </Location> Any help, like tips for debugging is appreciated!

• How do I reduce number of redundant requests with mod_perl properly?

  - by rassie

  In a fairly big legacy project, I've refactored several hairy modules into Moose classes. Each of these modules requires database access to (lazy) fetch its attributes. Since those objects are used pretty heavily, I want to reduce the number of redundant requests, for example for unchanged data. Now, how do I do that properly? I've got several alternatives: Implement caching in my Moose classes via a role to store them in memcached with expiration of 5-10 minutes (probably not too difficult, but tricky with lazy attributes) update: KiokuDB could probably help here, have to read up about attributes Migrate to DBIx::Class (needs to be done anyway) and implement caching on this level (DBIC will probably take most of the pain away just by itself) Somehow make my objects persist inside the mod_perl process (no clue how to do this :() How would you do this and what do you consider a sane way? Is caching data preferred on object or the ORM level?

• Programatical authentication in J2EE 6

  - by Kevin

  Hello, is it possible to authenticate programmatically a user in J2ee 6? Let me explain with some more details: I've got an existing Java SE project with Servlets and hibernate; where I manage manually all the authentication and access control: class Authenticator { int Id string username } Authenticator login(string username, string password) ; void doListData(Authenticator auth) { if (isLoggedIn(auth)) listData(); else doListError } void doUpdateData (Authenticator auth) { if (isLoggedAsAdmin(auth)) updateData() ; else doListError(); } void doListError () { listError() ; } And Im integrating J2ee/jpa/servlet 3/... (Glassfish 3) in this project. I've seen anotations like : @RolesAllowed ("viewer") void doListdata (...) { istData() ; } @RolesAllowed("admin") void doUpdateData (...) { updateData() ; } @PermotAll void dolisterror () { listerror() ; } but how can I manually state, in login(), that my user is in the admin and/or viewer role?

• Converting array to Drupal format

  - by theo

  Hi all, This statement gives me the value I want in Drupal (namely the last user role): global $user; return (end($user->roles)); however I need to convert it to this format: return array( 0 => array('value' => value for value), // You'll usually want to stop here. Provide more values // if you want your 'default value' to be multi-valued: 1 => array('value' => value for value), 2 => ... ); and I've got no idea how to (also, is this format a multidimensional array?)... Any ideas? Thanks for any help, Theo.

• HP to Cisco spanning tree root flapping

  - by Tim Brigham

  Per a recent question I recently configured both my HP (2x 2900) and Cisco (1x 3750) hardware to use MSTP for interoperability. I thought this was functional until I applied the change to the third device (HP switch 1 below) at which time the spanning tree root started flapping causing performance issues (5% packet loss) between my two HP switches. I'm not sure why. HP Switch 1 A4 connected to Cisco 1/0/1. HP Switch 2 B2 connected to Cisco 2/0/1. HP Switch 1 A2 connected to HP Switch 2 A1. I'd prefer the Cisco stack to act as the root. EDIT: There is one specific line - 'spanning-tree 1 path-cost 500000' in the HP switch 2 that I didn't add and was preexisting. I'm not sure if it could have the kind of impact that I'm describing. I'm more a security and monitoring guy then networking. EDIT 2: I'm starting to believe the problem lies in the fact that the value for my MST 0 instance on the Cisco is still at the default 32768. I worked up a diagram: This is based on every show command I could find for STP. I'll make this change after hours and see if it helps.

• SQL 2008 Database tuning advisor won't start

  - by Andrew Hancox

  For some reason I can't get DTA to connect to my development machine. It connects to a remote DB just fine but when I point it to my dev machine I get an error saying: Failed to initialize MSDB database for tuning (exit code: -1073741819). I'm pretty sure it's not a permissions issue since I've used profiler to capture what it's doing and all of the commands it's run so far look fine and are being run under my account which is associated with the sysadmin role, when I run them in sql management studio they go through fine. I'm pretty convinced that the problem is related to creating the objects in MSDB that are used by DTA but I tried creating these manually (I found scripts on the web) and it just seems to push the problem along the line slightly. I'm going out of my mind - have even tried reinstalling SQL but that's not fixed it. I'm using SQL 2008 with SP1 (10.0.2531) on windows server 2008 (patched up to date). SAVE ME!!!!!

• Are Colocation Cross Connects Worth While

  - by SvrGuy

  We currently operate three clusters of collocated machines in different data centers. Recently, I became aware that our newest data center will offer to cross connect us to a bandwidth provider free of charge. In the past, I never really investigated a cross connect for bandwidth because I figured that the rates would be similar to what we are paying the colo now and that it would reduce our resiliency (because we would only be using one or two carriers for IP, where as the colo uses, say 8 different providers). Then I saw an ad for hurricane electric internet services (http://he.net/cgi-bin/ip_transit_quote) that gave a price for IP transit at $1/Mbs, which is much better than the $30/Mb we pay for the blended bandwidth. What are people out there typically paying for bandwith via cross connect and how hard is to setup? Is my understanding that what you do is open agreemetns with two or three ISPs, cross connect to them and then configure your top of rack router on their network. Can you really get IP transit down to a couple of dollars per megabit per month just by doing the routing yourself? Or, is my understanding of cross connection fundamentally wrong?

• Alternate way to connect a vpn through a MIFI

  - by questor

  This has gotten to be a major problem at our company and depending on who I ask, the problem either does not really exist (mfr. and vendor) or is insoluble ( according to most users including techs who know how to prove their point). The problem involves getting a normal Windows 7 system to connect to a normal Server 2008 R2 Server over a cellular router (usually called a Mifi). A very few brands/models appear to work but the majority cannot make the connection. Since it is a cellular device, there are many variables that come into play and I wondered if anyone had ever found a consistent way to either make one work or else prove to the providers that their equipment was at fault. They all specifically state “VPN use” on the sales brochures. But few if any work. And those that do are not reliable. From a standpoint of pure knowledge, I just wondered if anyone knew the real reason why they fail? Pptp, L2tp, IPsec doesn’t matter. I have not tried Shrew or OpenVPN and am using strictly MS Windows protocols. Plenty of Google Searches back up my complaints but none seem to be any closer to knowing "why" they fail, just that they do. This is a "quest for knowledge"question. I don't expect a solution. Just a reason for the problem if anyone has any ideas.

• What's the shebang in Facebook URLs for?

  - by BoltClock

  I've just noticed that the long, convoluted Facebook URLs that we're used to now look like this: http://www.facebook.com/example.profile#!/pages/Some-Other-Page/123456789012345 As far as I can recall, earlier this year it was just a normal URL-fragment-like string (starting with #), without the exclamation mark. But now it's a shebang (#!), which I've previously only seen in shell scripts and Perl scripts. Does #! now play some special role in URLs, like for a certain Ajax framework or something since Facebook's interface is now largely Ajaxified? Or is it for some other purpose?

• Forms Authentication and Login controls

  - by DotnetDude

  I am upgrading a website written using ASP.NET 1.1 and the logic for the login page includes verifying the credentials, calling FormsAuthentication.SetAuthCookie() and populating the Session with the user information. I am updating this page to use Login controls and the Membership API and am trying to wrap my head around the concepts that have been changed. Most of the samples I see do not do anything on the login button event handler, so is the logic of setting the cookie abstracted out into the control? Also, how do I check if a user is logged in or not on other pages. Does it still store user information using the Session? How do I check if a user belongs to a particular role or not (Earlier, I would look in the Session object to do something like this) Is the Session a bad way of storing user info? Thanks

• Using OpenSessionInViewInterceptor with Hibernate and JSF 2

  - by sammy

  I'm building an application in Hibernate, Spring and JSF2 using only annotations. How can I take advantage of OpenSessionInViewInterceptor found in Spring to catch any hibernate session that might open within a bean? I'm trying to elegantly solve the common “failed to lazily initialize a collection of role: your.Class.assocation no session or session was closed.” problem when trying to read from a yet uninitialized list of POJOs inside another POJO (A Tag entity retrieved by a DAO that contains a List of Project objects I want to read). I've found this: http://www.paulcodding.com/blog/2008/01/21/using-the-opensessioninviewinterceptor-for-spring-hibernate3/ but failed to make use of it in my environment. Please provide a detailed answer, as the Internet is full of foggy, unhelpful tutorials. I'll also be greatful for an alternative solution, given a step-by-step instruction is provided.

• How can I use Moose with Test::Class?

  - by rassie

  I'm currently refactoring a test suite built up by a colleague and would like to use Test::Class[::Most] while doing so. As I started I figured out I could really use a couple of Moose roles to decouple code a little bit. However, it seems it's not quite possible -- I'm getting error messages like this one: Prototype mismatch: sub My::Test::Class::Base::blessed: none vs ($) at /usr/lib/perl5/vendor_perl/5.8.8/Sub/Exporter.pm line 896 So the question is: can I use Moose together with Test::Class and if so, how? PS: The code goes like this: package My::Test::Class::Base; use Moose; use Test::Class::Most; with 'My::Cool::Role'; has attr => ( ... );

• Pair programming: How should the pairs be chosen?

  - by Jon Seigel

  This topic has been covered peripherally in bits and pieces in some of the other pair-programming questions, but I want to (a) consolidate this knowledge into a separate question, and, most importantly, (b) go into much more depth on the subject. From the perspective of being an effective manager, how should pairs be arranged for pair programming to maximize both the happiness and productivity of the overall team? Some ideas to get started: Should two people never be paired (because of personalities, for example)? How much overlap in skillsets is needed? How much disconnect in skillsets is too much to overcome? (No two people will overlap 100%, and a disconnect in skills can be very beneficial to both people.) Should everyone pair with everyone else on a fixed/rotating basis? Should certain pairs be arranged to accomplish specific tasks? How important a role does HR play when growing or reorganizing the team?

Most of us have never met each other before, so I'm trying to create a questionnaire to help us find the appropriate roles for each team-member. We have the following responsibilities: Database design Programming User interface design Training Documentation / technical writing Network design Project management Business analysis Testing And we have the following roles: Project Manager Developer Tester Business Analyst Our group has people with various experience: a full-time graduate student, an associate director at the CME (Chicago Mercantile Exchange), full-time professionals, etc. Do any of you know of any tools that would help build a questionnaire or do you have a reference to an online questionnaire that can help us identify the most suitable role(s) for each team member?

• Jersey, Apache HTTPD, and javax.annotation.security usage

  - by Nick Klauer

  So I'm having a heck of a time trying to piece together what I think is a pretty simple implementation. This is very similar to another StackOverflow question only I can't leverage Tomcat to handle role based authentication. I have an Apache httpd server in front of my app that handles authentication and then passes LDAP roles to a Jersey service through Headers. I've created a servlet filter to parse the header and tease out the roles the request came from, which works fine globally to the app, but isn't fine-grained enough to dictate what an Admin could do that a User could not. I'm thinking I could use the javax.annotation.security annotations that JAX-RS supports, but I don't know how to take what I've parsed out using a servlet filter to set or instantiate the SecurityContext necessary for the roles @RolesAllowed.

• Programmatic authentication in JEE 6

  - by Kevin

  Hello, is it possible to authenticate programmatically a user in J2ee 6? Let me explain with some more details: I've got an existing Java SE project with Servlets and hibernate; where I manage manually all the authentication and access control: class Authenticator { int Id string username } Authenticator login(string username, string password) ; void doListData(Authenticator auth) { if (isLoggedIn(auth)) listData(); else doListError } void doUpdateData (Authenticator auth) { if (isLoggedAsAdmin(auth)) updateData() ; else doListError(); } void doListError () { listError() ; } And Im integrating J2ee/jpa/servlet 3/... (Glassfish 3) in this project. I've seen anotations like : @RolesAllowed ("viewer") void doListdata (...) { istData() ; } @RolesAllowed("admin") void doUpdateData (...) { updateData() ; } @PermotAll void dolisterror () { listerror() ; } but how can I manually state, in login(), that my user is in the admin and/or viewer role?

• Rails XML Builder - Code refactoring

  - by Vijay Dev

  I have written the following code in my Rails app to generate XML. I am using Aptana IDE to do Rails development and the IDE shows a warning that the code structure is identical in both the blocks. What changes can be done to the code to remove the duplicity in structure? Is there any other way to write the same? xml.roles do @rolesList.each do |r| xml.role(:id => r["role_id"], :name => r["role_name"]) end end xml.levels do @levelsList.each do |lvl| xml.level(:id => lvl["level_id"], :name => lvl["level_name"]) end end

• how to get the value of a kendoui dropdown list selected value in a listview

  - by user1568738

  am having Some kendoui listviews which consists of kendoui dropdown lists and i want to get those dropdown list selected values. To do this am trying, $("#cnty1").val(); and here is my dropdownlist,i.e., list of countries coming from Database table, <input select STYLE="width:90px;height:auto" id ="cnty1" data-bind="value:cnty1" name="cnty1" data-type="string" data-text-field="cnty" data-value-field="cntyid" data-source="sourcedata1" class="k-d" data-role="dropdownlist" /> <span data-for="cnty1" class="k-invalid-msg"></span> here cnty1 is the id of the dropdown list, but am not getting the value instead am getting "id" of the slected value but not the selected value. And also if the value is not selected am getting the first value id by using $("#cnty1").val(); So, please suggest me a solution so that, 1) I should get only the Selected value and 2) Value of the dropdown list Only if the user selects a value from the list, but don't get the value of the list without selecting.

• How to access drop down list from EditItemTemplate of FormView

  - by IrfanRaza

  Hello friends, I have a formview on my aspx page containing various controls arranged using table. There is a DDL "cboClients" which i need to enable or disabled depending upon role within Edit mode. The problem here is that i am not able to get that control using FindControl() method. I have tried following code - DropDownList ddl = null; if (FormView1.Row != null) { ddl = (DropDownList)FormView1.Row.FindControl("cboClients"); ddl.Enabled=false; } Even I ave used the DataBound event of the same control - protected void cboClients_DataBound(object sender, EventArgs e) { if (FormView1.CurrentMode == FormViewMode.Edit) { if ((Session["RoleName"].ToString().Equals("Clients")) || (Session["RoleName"].ToString().Equals("Suppliers"))) { DropDownList ddl = (DropDownList)sender; ddl.Enabled = false; } } } But this databound event occurs only once, but not when formview mode is changed. Can anyone provide me proper solution? Thanks for sharing your time.
