In CakePHP, how to leave all prefixes?

- by Victor Piousbox

I have a link that goes like this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add')); I suspect it doesn't work (Firefox says the redirect will never complete), so I did this: $this->Html->link('Welcome', array('controller' => 'users', 'action' => 'add', 'my'=>false)); 'my' is a prefix. I also have 'admin', 'ajax', and 'rss'. So now instead of pointing to /users/add or /my/users/add, the link points to /rss/users/add. The link is in a header, in a layout so I don't know which prefix it will be invoked from. I want to go to /users/add, that is, leave all prefixes altogether. How do I do that in CakePHP? I'm using 1.3 version.

Object oriented n-tier design. Am I abstracting too much? Or not enough?

- by max

Hi guys, I'm building my first enterprise grade solution (at least I'm attempting to make it enterprise grade). I'm trying to follow best practice design patterns but am starting to worry that I might be going too far with abstraction. I'm trying to build my asp.net webforms (in C#) app as an n-tier application. I've created a Data Access Layer using an XSD strongly-typed dataset that interfaces with a SQL server backend. I access the DAL through some Business Layer Objects that I've created on a 1:1 basis to the datatables in the dataset (eg, a UsersBLL class for the Users datatable in the dataset). I'm doing checks inside the BLL to make sure that data passed to DAL is following the business rules of the application. That's all well and good. Where I'm getting stuck though is the point at which I connect the BLL to the presentation layer. For example, my UsersBLL class deals mostly with whole datatables, as it's interfacing with the DAL. Should I now create a separate "User" (Singular) class that maps out the properties of a single user, rather than multiple users? This way I don't have to do any searching through datatables in the presentation layer, as I could use the properties created in the User class. Or would it be better to somehow try to handle this inside the UsersBLL? Sorry if this sounds a little complicated... Below is the code from the UsersBLL: using System; using System.Data; using PedChallenge.DAL.PedDataSetTableAdapters; [System.ComponentModel.DataObject] public class UsersBLL { private UsersTableAdapter _UsersAdapter = null; protected UsersTableAdapter Adapter { get { if (_UsersAdapter == null) _UsersAdapter = new UsersTableAdapter(); return _UsersAdapter; } } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, true)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsers() { return Adapter.GetUsers(); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUserByUserID(int userID) { return Adapter.GetUserByUserID(userID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByTeamID(int teamID) { return Adapter.GetUsersByTeamID(teamID); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)] public PedChallenge.DAL.PedDataSet.UsersDataTable GetUsersByEmail(string Email) { return Adapter.GetUserByEmail(Email); } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Insert, true)] public bool AddUser(int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { // Create a new UsersRow instance PedChallenge.DAL.PedDataSet.UsersDataTable Users = new PedChallenge.DAL.PedDataSet.UsersDataTable(); PedChallenge.DAL.PedDataSet.UsersRow user = Users.NewUsersRow(); if (UserExists(Users, Email) == true) return false; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Add the new user Users.AddUsersRow(user); int rowsAffected = Adapter.Update(Users); // Return true if precisely one row was inserted, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Update, true)] public bool UpdateUser(int userID, int? teamID, string FirstName, string LastName, string Email, string Role, int LocationID) { PedChallenge.DAL.PedDataSet.UsersDataTable Users = Adapter.GetUserByUserID(userID); if (Users.Count == 0) // no matching record found, return false return false; PedChallenge.DAL.PedDataSet.UsersRow user = Users[0]; if (teamID == null) user.SetTeamIDNull(); else user.TeamID = teamID.Value; user.FirstName = FirstName; user.LastName = LastName; user.Email = Email; user.Role = Role; user.LocationID = LocationID; // Update the product record int rowsAffected = Adapter.Update(user); // Return true if precisely one row was updated, // otherwise false return rowsAffected == 1; } [System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Delete, true)] public bool DeleteUser(int userID) { int rowsAffected = Adapter.Delete(userID); // Return true if precisely one row was deleted, // otherwise false return rowsAffected == 1; } private bool UserExists(PedChallenge.DAL.PedDataSet.UsersDataTable users, string email) { // Check if user email already exists foreach (PedChallenge.DAL.PedDataSet.UsersRow userRow in users) { if (userRow.Email == email) return true; } return false; } } Some guidance in the right direction would be greatly appreciated!! Thanks all! Max

Count number of messages per user

- by Pr0no

Consider the following tables: users messages ----------------- ----------------------- user_id messages msg_id user_id content ----------------- ----------------------- 1 0 1 1 foo 2 0 2 1 bar 3 0 3 1 foobar 4 3 baz 5 3 bar I want to count the number of messages per user and insert the outcome into users.messages, like this: users ----------------- user_id messages ----------------- 1 3 2 0 3 2 I could use PHP to perform this operation, pseudo: foreach ($user_id in users) { $count = select count(msg_id) from messages where user_id = $user_id update users set messages = $count } But this is probably very inefficient as compared to one query executed in MySQL directly: UPDATE users SET messages = ( SELECT COUNT(msg_id) FROM messages ) But I'm sure this is not a proper query. Therefore, any help would be appreciated :-)

Minimizing calls to database in rails

- by ming yeow

Hi guys, i am familiar with memcached and eager loading, but neither seems to solve the problem i am facing. My main performance lag comes from hundreds of data retrieval calls from the database. The tricky thing is that I do not know which set of users i need to retrieve until i have several steps of computation. I can refactor my code, but i was wondering how you experts handle this situation? I think it should be a fairly common situation def newsfeed - find out which users i need - retrieve those users via DB - find out which events happened for these users - for each of those events - retrieve new set of users - find out which groups are relevant - for each of those groups - retrieve new set of users - etc, etc end

Is there any reason I shouldn't do database calls from the destructor?

- by ryeguy

I want to create a sort of datamapper library, where you'd do something like this: $users = Users::getTable(); $users->add($newUser1); $users->add($newUser2); Now $users contains 2 user records, but they aren't yet persisted to the database. To be efficient, I'd like to flush them all at once. I would like to have a flush() method to do this (not an issue), but I'd also like for it to happen implicitly when the $users table reference falls out of scope. Is there any reason I shouldn't do this in the destructor?

app-engine-rest-server to raise KeyError("name %s already used" % model_name)

- by fx

I'm playing with the project appengine-rest-server to create the REST webservices for all the existing models. I got a strange error, the first time I query the browser: http://localhost:8080/rest/metadata/user, it gives me the result: <xs:schema> - <xs:element name="user"> - <xs:complexType> - <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="key" type="xs:normalizedString"/> <xs:element maxOccurs="1" minOccurs="0" name="surname" type="xs:string"/> <xs:element maxOccurs="1" minOccurs="0" name="firstname" type="xs:string"/> <xs:element maxOccurs="1" minOccurs="0" name="ages" type="xs:long"/> <xs:element maxOccurs="1" minOccurs="0" name="sex" type="xs:boolean"/> <xs:element maxOccurs="1" minOccurs="0" name="updatedDate" type="xs:dateTime"/> <xs:element maxOccurs="1" minOccurs="0" name="createdDate" type="xs:dateTime"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> But refreshing the page, gives me this error: Traceback (most recent call last): File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3185, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 3128, in _Dispatch base_env_dict=env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 515, in Dispatch base_env_dict=base_env_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2387, in Dispatch self._module_dict) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2297, in ExecuteCGI reset_modules = exec_script(handler_path, cgi_path, hook) File "/Users/foo/Documents/AppEngine/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py", line 2195, in ExecuteOrImportScript script_module.main() File "/Users/foo/Documents/AppEngine/helloworld/main.py", line 48, in main rest.Dispatcher.add_models({"user": UserModel}) File "/Users/foo/Documents/AppEngine/helloworld/rest/__init__.py", line 845, in add_models cls.add_model(model_name, model_type) File "/Users/foo/Documents/AppEngine/helloworld/rest/__init__.py", line 863, in add_model raise KeyError("name %s already used" % model_name) KeyError: 'name user already used' Can someone give me the explanation on why it happens? Restarting the server, run on the browser again I get the xml result, but refreshing causes the error. Is it a bug in the appengine-rest-server application or it is in my code? My helloworld application is available for download here.

LIKE and % Wildcard in Doctrine's findBy*()

- by 01010011

Hi, How do I write the following MySQL query using Doctrine's findBy*() method?: SELECT column_name1, column_name2 FROM table_name WHERE column_name3 LIKE '%search_key%'; For Example, to fetch multiple rows from a column named "ColumnName" (below) using Doctrine: $users = Doctrine::getTable('User')->findByColumnName('active'); echo $users[0]->username; echo $users[1]->username; I tried: $search_key = 'some value'; $users = Doctrine::getTable('User')->findByColumnName('%$search_key%'); echo $users[0]->username; echo $users[1]->username; and I got no errors, but nothing displayed. Any assistance will be really appreciated. Thanks in advance.

I have a very long and repetitive python path, where do I look to correct this?

- by ninja123

I know it is probably not necessary to paste the whole path, but just for the record I have done so below. Whenever I run a python command, it takes a long time to load this path I suppose. I have checked in .bash_profile and only have these two lines: export PATH=/Users/username/bin:/opt/local/Library/Frameworks/Python.framework/Versions/2.5/bin:/opt/local/bin:/opt/local/sbin:/opt/local/apache2/bin:$PATH export PYTHONPATH=/opt/local/lib/python2.5/site-packages/ And my python path as outputed by Django's debug is: Python path : ['/Users/username/Sites/videocluster/eggs/ipython-0.10-py2.5.egg', '/Users/username/Sites/videocluster/eggs/South-0.6.1-py2.5.egg', '/Users/username/Sites/videocluster/eggs/django_markitup-0.5.2-py2.5.egg', '/Users/username/Sites/videocluster/eggs/DateTime-2.12.0-py2.5.egg', '/Users/username/Sites/videocluster/eggs/Markdown-2.0.3-py2.5.egg', '/Users/username/Sites/videocluster/eggs/PIL-1.1.7-py2.5-macosx-10.5-i386.egg', '/Users/username/Sites/videocluster/eggs/djangorecipe-0.20-py2.5.egg', '/Users/username/Sites/videocluster/eggs/zc.recipe.egg-1.2.3b2-py2.5.egg', '/Users/username/Sites/videocluster/eggs/zc.buildout-1.5.0b2-py2.5.egg', '/Users/username/Sites/videocluster/eggs/pytz-2010h-py2.5.egg', '/Users/username/Sites/videocluster/eggs/zope.interface-3.6.1-py2.5-macosx-10.5-i386.egg', '/Users/username/Sites/videocluster/eggs/setuptools-0.6c11-py2.5.egg', '/Users/username/Sites/videocluster/parts/django', '/Users/username/Sites/videocluster', '/Users/username/Sites/videocluster/bin', '/opt/local/lib/python2.5/site-packages/setuptools_git-0.3.3-py2.5.egg', '/opt/local/lib/python2.5/site-packages/pysqlite-2.5.5-py2.5-macosx-10.5-i386.egg', '/opt/local/lib/python2.5/site-packages/CouchDB-0.5-py2.5.egg', '/opt/local/lib/python2.5/site-packages/httplib2-0.4.0-py2.5.egg', '/opt/local/lib/python2.5/site-packages/PyYAML-3.08-py2.5-macosx-10.5-i386.egg', '/opt/local/lib/python2.5/site-packages/simple_db_migrate-1.2.8-py2.5.egg', '/opt/local/lib/python2.5/site-packages/PyDispatcher-2.0.1-py2.5.egg', '/opt/local/lib/python2.5/site-packages/pyOpenSSL-0.9-py2.5-macosx-10.5-i386.egg', '/opt/local/lib/python2.5/site-packages/greenlet-0.2-py2.5-macosx-10.5-i386.egg', '/opt/local/lib/python2.5/site-packages/Supay-0.0.2-py2.5.egg', '/opt/local/lib/python2.5/site-packages/configobj-4.6.0-py2.5.egg', '/opt/local/lib/python2.5/site-packages/Fabric-0.9b1-py2.5.egg', '/opt/local/lib/python2.5/site-packages/fudge-0.9.3-py2.5.egg', '/opt/local/lib/python2.5/site-packages/pydelicious-0.5.3-py2.5.egg', '/opt/local/lib/python2.5/site-packages/feedparser-4.1-py2.5.egg', '/opt/local/lib/python2.5/site-packages/github_cli-0.2.5.2-py2.5.egg', '/opt/local/lib/python2.5/site-packages/simplejson-2.0.9-py2.5-macosx-10.5-i386.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', '/opt/local/lib/python2.5/site-packages/setuptools-0.6c11-py2.5.egg', ......(repeating).......

MonoTouch App Crashes When Returning From MFMailComposeViewController

My MonoTouch Version Info: Release ID: 20401003 Git revision: 2f1746af36f421d262dcd2b0542ce86b12158f02 Build date: 2010-12-23 23:13:38+0000 The MFMailComposeViewController is displayed and works correctly as a dialog using the following code: if (MFMailComposeViewController.CanSendMail) { MFMailComposeViewController mail; mail = new MFMailComposeViewController (); mail.SetSubject ("Subject Test"); mail.SetMessageBody ("Body Test", false); mail.Finished += HandleMailFinished; this.navigationController.PresentModalViewController (mail, true); } else { new UIAlertView ("Mail Failed", "Mail Failed", null, "OK", null).Show (); } However, once the user selects Cancel | Delete Draft or Cancel | Save Draft or Send, the App throws a run-time error like the following: Stacktrace: at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at MonoTouch.UIKit.UIApplication.Main (string[],string,string) [0x00038] in /Users/plasma/Source/iphone/monotouch/UIKit/UIApplication.cs:26 at MonoTouch.UIKit.UIApplication.Main (string[]) [0x00000] in /Users/plasma/Source/iphone/monotouch/UIKit/UIApplication.cs:31 at MailDialog.Application.Main (string[]) [0x00000] in /Users/rrkhan/Projects/Sandbox/MailDialog/Main.cs:15 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) Native stacktrace: 0 MailDialog 0x000be66f mono_handle_native_sigsegv + 343 1 MailDialog 0x0000e43e mono_sigsegv_signal_handler + 313 2 libSystem.B.dylib 0x903e946b _sigtramp + 43 3 ???

Windows Azure: Backup Services Release, Hyper-V Recovery Manager, VM Enhancements, Enhanced Enterprise Management Support

- by ScottGu

This morning we released a huge set of updates to Windows Azure. These new capabilities include: Backup Services: General Availability of Windows Azure Backup Services Hyper-V Recovery Manager: Public preview of Windows Azure Hyper-V Recovery Manager Virtual Machines: Delete Attached Disks, Availability Set Warnings, SQL AlwaysOn Configuration Active Directory: Securely manage hundreds of SaaS applications Enterprise Management: Use Active Directory to Better Manage Windows Azure Windows Azure SDK 2.2: A massive update of our SDK + Visual Studio tooling support All of these improvements are now available to use immediately. Below are more details about them. Backup Service: General Availability Release of Windows Azure Backup Today we are releasing Windows Azure Backup Service as a general availability service. This release is now live in production, backed by an enterprise SLA, supported by Microsoft Support, and is ready to use for production scenarios. Windows Azure Backup is a cloud based backup solution for Windows Server which allows files and folders to be backed up and recovered from the cloud, and provides off-site protection against data loss. The service provides IT administrators and developers with the option to back up and protect critical data in an easily recoverable way from any location with no upfront hardware cost. Windows Azure Backup is built on the Windows Azure platform and uses Windows Azure blob storage for storing customer data. Windows Server uses the downloadable Windows Azure Backup Agent to transfer file and folder data securely and efficiently to the Windows Azure Backup Service. Along with providing cloud backup for Windows Server, Windows Azure Backup Service also provides capability to backup data from System Center Data Protection Manager and Windows Server Essentials, to the cloud. All data is encrypted onsite before it is sent to the cloud, and customers retain and manage the encryption key (meaning the data is stored entirely secured and can’t be decrypted by anyone but yourself). Getting Started To get started with the Windows Azure Backup Service, create a new Backup Vault within the Windows Azure Management Portal. Click New->Data Services->Recovery Services->Backup Vault to do this: Once the backup vault is created you’ll be presented with a simple tutorial that will help guide you on how to register your Windows Servers with it: Once the servers you want to backup are registered, you can use the appropriate local management interface (such as the Microsoft Management Console snap-in, System Center Data Protection Manager Console, or Windows Server Essentials Dashboard) to configure the scheduled backups and to optionally initiate recoveries. You can follow these tutorials to learn more about how to do this: Tutorial: Schedule Backups Using the Windows Azure Backup Agent This tutorial helps you with setting up a backup schedule for your registered Windows Servers. Additionally, it also explains how to use Windows PowerShell cmdlets to set up a custom backup schedule. Tutorial: Recover Files and Folders Using the Windows Azure Backup Agent This tutorial helps you with recovering data from a backup. Additionally, it also explains how to use Windows PowerShell cmdlets to do the same tasks. Below are some of the key benefits the Windows Azure Backup Service provides: Simple configuration and management. Windows Azure Backup Service integrates with the familiar Windows Server Backup utility in Windows Server, the Data Protection Manager component in System Center and Windows Server Essentials, in order to provide a seamless backup and recovery experience to a local disk, or to the cloud. Block level incremental backups. The Windows Azure Backup Agent performs incremental backups by tracking file and block level changes and only transferring the changed blocks, hence reducing the storage and bandwidth utilization. Different point-in-time versions of the backups use storage efficiently by only storing the changes blocks between these versions. Data compression, encryption and throttling. The Windows Azure Backup Agent ensures that data is compressed and encrypted on the server before being sent to the Windows Azure Backup Service over the network. As a result, the Windows Azure Backup Service only stores encrypted data in the cloud storage. The encryption key is not available to the Windows Azure Backup Service, and as a result the data is never decrypted in the service. Also, users can setup throttling and configure how the Windows Azure Backup service utilizes the network bandwidth when backing up or restoring information. Data integrity is verified in the cloud. In addition to the secure backups, the backed up data is also automatically checked for integrity once the backup is done. As a result, any corruptions which may arise due to data transfer can be easily identified and are fixed automatically. Configurable retention policies for storing data in the cloud. The Windows Azure Backup Service accepts and implements retention policies to recycle backups that exceed the desired retention range, thereby meeting business policies and managing backup costs. Hyper-V Recovery Manager: Now Available in Public Preview I’m excited to also announce the public preview of a new Windows Azure Service – the Windows Azure Hyper-V Recovery Manager (HRM). Windows Azure Hyper-V Recovery Manager helps protect your business critical services by coordinating the replication and recovery of System Center Virtual Machine Manager 2012 SP1 and System Center Virtual Machine Manager 2012 R2 private clouds at a secondary location. With automated protection, asynchronous ongoing replication, and orderly recovery, the Hyper-V Recovery Manager service can help you implement Disaster Recovery and restore important services accurately, consistently, and with minimal downtime. Application data in an Hyper-V Recovery Manager scenarios always travels on your on-premise replication channel. Only metadata (such as names of logical clouds, virtual machines, networks etc.) that is needed for orchestration is sent to Azure. All traffic sent to/from Azure is encrypted. You can begin using Windows Azure Hyper-V Recovery today by clicking New->Data Services->Recovery Services->Hyper-V Recovery Manager within the Windows Azure Management Portal. You can read more about Windows Azure Hyper-V Recovery Manager in Brad Anderson’s 9-part series, Transform the datacenter. To learn more about setting up Hyper-V Recovery Manager follow our detailed step-by-step guide. Virtual Machines: Delete Attached Disks, Availability Set Warnings, SQL AlwaysOn Today’s Windows Azure release includes a number of nice updates to Windows Azure Virtual Machines. These improvements include: Ability to Delete both VM Instances + Attached Disks in One Operation Prior to today’s release, when you deleted VMs within Windows Azure we would delete the VM instance – but not delete the drives attached to the VM. You had to manually delete these yourself from the storage account. With today’s update we’ve added a convenience option that now allows you to either retain or delete the attached disks when you delete the VM: We’ve also added the ability to delete a cloud service, its deployments, and its role instances with a single action. This can either be a cloud service that has production and staging deployments with web and worker roles, or a cloud service that contains virtual machines. To do this, simply select the Cloud Service within the Windows Azure Management Portal and click the “Delete” button: Warnings on Availability Sets with Only One Virtual Machine In Them One of the nice features that Windows Azure Virtual Machines supports is the concept of “Availability Sets”. An “availability set” allows you to define a tier/role (e.g. webfrontends, databaseservers, etc) that you can map Virtual Machines into – and when you do this Windows Azure separates them across fault domains and ensures that at least one of them is always available during servicing operations. This enables you to deploy applications in a high availability way. One issue we’ve seen some customers run into is where they define an availability set, but then forget to map more than one VM into it (which defeats the purpose of having an availability set). With today’s release we now display a warning in the Windows Azure Management Portal if you have only one virtual machine deployed in an availability set to help highlight this: You can learn more about configuring the availability of your virtual machines here. Configuring SQL Server Always On SQL Server Always On is a great feature that you can use with Windows Azure to enable high availability and DR scenarios with SQL Server. Today’s Windows Azure release makes it even easier to configure SQL Server Always On by enabling “Direct Server Return” endpoints to be configured and managed within the Windows Azure Management Portal. Previously, setting this up required using PowerShell to complete the endpoint configuration. Starting today you can enable this simply by checking the “Direct Server Return” checkbox: You can learn more about how to use direct server return for SQL Server AlwaysOn availability groups here. Active Directory: Application Access Enhancements This summer we released our initial preview of our Application Access Enhancements for Windows Azure Active Directory. This service enables you to securely implement single-sign-on (SSO) support against SaaS applications (including Office 365, SalesForce, Workday, Box, Google Apps, GitHub, etc) as well as LOB based applications (including ones built with the new Windows Azure AD support we shipped last week with ASP.NET and VS 2013). Since the initial preview we’ve enhanced our SAML federation capabilities, integrated our new password vaulting system, and shipped multi-factor authentication support. We've also turned on our outbound identity provisioning system and have it working with hundreds of additional SaaS Applications: Earlier this month we published an update on dates and pricing for when the service will be released in general availability form. In this blog post we announced our intention to release the service in general availability form by the end of the year. We also announced that the below features would be available in a free tier with it: SSO to every SaaS app we integrate with – Users can Single Sign On to any app we are integrated with at no charge. This includes all the top SAAS Apps and every app in our application gallery whether they use federation or password vaulting. Application access assignment and removal – IT Admins can assign access privileges to web applications to the users in their active directory assuring that every employee has access to the SAAS Apps they need. And when a user leaves the company or changes jobs, the admin can just as easily remove their access privileges assuring data security and minimizing IP loss User provisioning (and de-provisioning) – IT admins will be able to automatically provision users in 3rd party SaaS applications like Box, Salesforce.com, GoToMeeting, DropBox and others. We are working with key partners in the ecosystem to establish these connections, meaning you no longer have to continually update user records in multiple systems. Security and auditing reports – Security is a key priority for us. With the free version of these enhancements you'll get access to our standard set of access reports giving you visibility into which users are using which applications, when they were using them and where they are using them from. In addition, we'll alert you to un-usual usage patterns for instance when a user logs in from multiple locations at the same time. Our Application Access Panel – Users are logging in from every type of devices including Windows, iOS, & Android. Not all of these devices handle authentication in the same manner but the user doesn't care. They need to access their apps from the devices they love. Our Application Access Panel will support the ability for users to access access and launch their apps from any device and anywhere. You can learn more about our plans for application management with Windows Azure Active Directory here. Try out the preview and start using it today. Enterprise Management: Use Active Directory to Better Manage Windows Azure Windows Azure Active Directory provides the ability to manage your organization in a directory which is hosted entirely in the cloud, or alternatively kept in sync with an on-premises Windows Server Active Directory solution (allowing you to seamlessly integrate with the directory you already have). With today’s Windows Azure release we are integrating Windows Azure Active Directory even more within the core Windows Azure management experience, and enabling an even richer enterprise security offering. Specifically: 1) All Windows Azure accounts now have a default Windows Azure Active Directory created for them. You can create and map any users you want into this directory, and grant administrative rights to manage resources in Windows Azure to these users. 2) You can keep this directory entirely hosted in the cloud – or optionally sync it with your on-premises Windows Server Active Directory. Both options are free. The later approach is ideal for companies that wish to use their corporate user identities to sign-in and manage Windows Azure resources. It also ensures that if an employee leaves an organization, his or her access control rights to the company’s Windows Azure resources are immediately revoked. 3) The Windows Azure Service Management APIs have been updated to support using Windows Azure Active Directory credentials to sign-in and perform management operations. Prior to today’s release customers had to download and use management certificates (which were not scoped to individual users) to perform management operations. We still support this management certificate approach (don’t worry – nothing will stop working). But we think the new Windows Azure Active Directory authentication support enables an even easier and more secure way for customers to manage resources going forward. 4) The Windows Azure SDK 2.2 release (which is also shipping today) includes built-in support for the new Service Management APIs that authenticate with Windows Azure Active Directory, and now allow you to create and manage Windows Azure applications and resources directly within Visual Studio using your Active Directory credentials. This, combined with updated PowerShell scripts that also support Active Directory, enables an end-to-end enterprise authentication story with Windows Azure. Below are some details on how all of this works: Subscriptions within a Directory As part of today’s update, we have associated all existing Window Azure accounts with a Windows Azure Active Directory (and created one for you if you don’t already have one). When you login to the Windows Azure Management Portal you’ll now see the directory name in the URI of the browser. For example, in the screen-shot below you can see that I have a “scottgu” directory that my subscriptions are hosted within: Note that you can continue to use Microsoft Accounts (formerly known as Microsoft Live IDs) to sign-into Windows Azure. These map just fine to a Windows Azure Active Directory – so there is no need to create new usernames that are specific to a directory if you don’t want to. In the scenario above I’m actually logged in using my @hotmail.com based Microsoft ID which is now mapped to a “scottgu” active directory that was created for me. By default everything will continue to work just like you used to before. Manage your Directory You can manage an Active Directory (including the one we now create for you by default) by clicking the “Active Directory” tab in the left-hand side of the portal. This will list all of the directories in your account. Clicking one the first time will display a getting started page that provides documentation and links to perform common tasks with it: You can use the built-in directory management support within the Windows Azure Management Portal to add/remove/manage users within the directory, enable multi-factor authentication, associate a custom domain (e.g. mycompanyname.com) with the directory, and/or rename the directory to whatever friendly name you want (just click the configure tab to do this). You can also setup the directory to automatically sync with an on-premises Active Directory using the “Directory Integration” tab. Note that users within a directory by default do not have admin rights to login or manage Windows Azure based resources. You still need to explicitly grant them co-admin permissions on a subscription for them to login or manage resources in Windows Azure. You can do this by clicking the Settings tab on the left-hand side of the portal and then by clicking the administrators tab within it. Sign-In Integration within Visual Studio If you install the new Windows Azure SDK 2.2 release, you can now connect to Windows Azure from directly inside Visual Studio without having to download any management certificates. You can now just right-click on the “Windows Azure” icon within the Server Explorer and choose the “Connect to Windows Azure” context menu option to do so: Doing this will prompt you to enter the email address of the username you wish to sign-in with (make sure this account is a user in your directory with co-admin rights on a subscription): You can use either a Microsoft Account (e.g. Windows Live ID) or an Active Directory based Organizational account as the email. The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio server explorer and be available to start using: No downloading of management certificates required. All of the authentication was handled using your Windows Azure Active Directory! Manage Subscriptions across Multiple Directories If you have already have multiple directories and multiple subscriptions within your Windows Azure account, we have done our best to create a good default mapping of your subscriptions->directories as part of today’s update. If you don’t like the default subscription-to-directory mapping we have done you can click the Settings tab in the left-hand navigation of the Windows Azure Management Portal and browse to the Subscriptions tab within it: If you want to map a subscription under a different directory in your account, simply select the subscription from the list, and then click the “Edit Directory” button to choose which directory to map it to. Mapping a subscription to a different directory takes only seconds and will not cause any of the resources within the subscription to recycle or stop working. We’ve made the directory->subscription mapping process self-service so that you always have complete control and can map things however you want. Filtering By Directory and Subscription Within the Windows Azure Management Portal you can filter resources in the portal by subscription (allowing you to show/hide different subscriptions). If you have subscriptions mapped to multiple directory tenants, we also now have a filter drop-down that allows you to filter the subscription list by directory tenant. This filter is only available if you have multiple subscriptions mapped to multiple directories within your Windows Azure Account: Windows Azure SDK 2.2 Today we are also releasing a major update of our Windows Azure SDK. The Windows Azure SDK 2.2 release adds some great new features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter I’ll post a follow-up blog shortly with more details about all of the above. Additional Updates In addition to the above enhancements, today’s release also includes a number of additional improvements: AutoScale: Richer time and date based scheduling support (set different rules on different dates) AutoScale: Ability to Scale to Zero Virtual Machines (very useful for Dev/Test scenarios) AutoScale: Support for time-based scheduling of Mobile Service AutoScale rules Operation Logs: Auditing support for Service Bus management operations Today we also shipped a major update to the Windows Azure SDK – Windows Azure SDK 2.2. It has so much goodness in it that I have a whole second blog post coming shortly on it! :-) Summary Today’s Windows Azure release enables a bunch of great new scenarios, and enables a much richer enterprise authentication offering. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today. Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

ASP.NET and WIF: Showing custom profile username as User.Identity.Name

- by DigiMortal

I am building ASP.NET MVC application that uses external services to authenticate users. For ASP.NET users are fully authenticated when they are redirected back from external service. In system they are logically authenticated when they have created user profiles. In this posting I will show you how to force ASP.NET MVC controller actions to demand existence of custom user profiles. Using external authentication sources with AppFabric Suppose you want to be user-friendly and you don’t force users to keep in mind another username/password when they visit your site. You can accept logins from different popular sites like Windows Live, Facebook, Yahoo, Google and many more. If user has account in some of these services then he or she can use his or her account to log in to your site. If you have community site then you usually have support for user profiles too. Some of these providers give you some information about users and other don’t. So only thing in common you get from all those providers is some unique ID that identifies user in service uniquely. Image above shows you how new user joins your site. Existing users who already have profile are directed to users homepage after they are authenticated. You can read more about how to solve semi-authorized users problem from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages. The other problem is related to usernames that we don’t get from all identity providers. Why is IIdentity.Name sometimes empty? The problem is described more specifically in my blog posting Identifying AppFabric Access Control Service users uniquely. Shortly the problem is that not all providers have claim called http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name. The following diagram illustrates what happens when user got token from AppFabric ACS and was redirected to your site. Now, when user was authenticated using Windows Live ID then we don’t have name claim in token and that’s why User.Identity.Name is empty. Okay, we can force nameidentifier to be used as name (we can do it in web.config file) but we have user profiles and we want username from profile to be shown when username is asked. Modifying name claim Now let’s force IClaimsIdentity to use username from our user profiles. You can read more about my profiles topic from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages and you can find some useful extension methods for claims identity from my blog posting Identifying AppFabric Access Control Service users uniquely. Here is what we do to set User.Identity.Name: we will check if user has profile, if user has profile we will check if User.Identity.Name matches the name given by profile, if names does not match then probably identity provider returned some name for user, we will remove name claim and recreate it with correct username, we will add new name claim to claims collection. All this stuff happens in Application_AuthorizeRequest event of our web application. The code is here. protected void Application_AuthorizeRequest() { if (string.IsNullOrEmpty(User.Identity.Name)) { var identity = User.Identity; var profile = identity.GetProfile(); if (profile != null) { if (profile.UserName != identity.Name) { identity.RemoveName(); var claim = new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", profile.UserName); var claimsIdentity = (IClaimsIdentity)identity; claimsIdentity.Claims.Add(claim); } } } } RemoveName extension method is simple – it looks for name claims of IClaimsIdentity claims collection and removes them. public static void RemoveName(this IIdentity identity) { if (identity == null) return; var claimsIndentity = identity as ClaimsIdentity; if (claimsIndentity == null) return; for (var i = claimsIndentity.Claims.Count - 1; i >= 0; i--) { var claim = claimsIndentity.Claims[i]; if (claim.ClaimType == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name") claimsIndentity.Claims.RemoveAt(i); } } And we are done. Now User.Identity.Name returns the username from user profile and you can use it to show username of current user everywhere in your site. Conclusion Mixing AppFabric Access Control Service and Windows Identity Foundation with custom authorization logic is not impossible but a little bit tricky. This posting finishes my little series about AppFabric ACS and WIF for this time and hopefully you found some useful tricks, tips, hacks and code pieces you can use in your own applications.

Updated Security Baseline (7u45) impacts Java 7u40 and before with High Security settings

- by costlow

The Java Security Baseline has been increased from 7u25 to 7u45. For versions of Java below 7u45, this means unsigned Java applets or Java applets that depend on Javascript LiveConnect calls will be blocked when using the High Security setting in the Java Control Panel. This issue only affects Applets and Web Start applications. It does not affect other types of Java applications. The Short Answer Users upgrading to Java 7 update 45 will automatically fix this and is strongly recommended. The More Detailed Answer There are two items involved as described on the deployment flowchart: The Security Baseline – a dynamically updated attribute that checks to see which Java version contains the most recent security patches. The Security Slider – the user-controlled setting of when to prompt/run/block applets. The Security Baseline Java clients periodically check in to understand what version contains the most recent security patches. Versions are released in-between that contain bug fixes. For example: 7u25 (July 2013) was the previous secure baseline. 7u40 contained bug fixes. Because this did not contain security patches, users were not required to upgrade and were welcome to remain on 7u25. When 7u45 was released (October, 2013), this critical patch update contained security patches and raised the secure baseline. Users are required to upgrade from earlier versions. For users that are not regularly connected to the internet, there is a built in Expiration Date. Because of the pre-established quarterly critical patch updates, we are able to determine an approximate date of the next version. A critical patch released in July will have its successor released, at latest, in July + 3 months: October. The Security Slider The security slider is located within the Java control panel and determines which Applets & Web Start applications will prompt, which will run, and which will be blocked. One of the questions used to determine prompt/run/block is, “At or Above the Security Baseline.” The Combination JavaScript calls made from LiveConnect do not reside within signed JAR files, so they are considered to be unsigned code. This is correct within networked systems even if the domain uses HTTPS because signed JAR files represent signed "data at rest" whereas TLS (often called SSL) literally stands for "Transport Level Security" and secures the communication channel, not the contents/code within the channel. The resulting flow of users who click "update later" is: Is the browser plug-in registered and allowed to run? Yes. Does a rule exist for this RIA? No rules apply. Does the RIA have a valid signature? Yes and not revoked. Which security prompt is needed? JRE is below the baseline. This is because 7u45 is the baseline and the user, clicked "upgrade later." Under the default High setting, Unsigned code is set to "Don’t Run" so users see: Additional Notes End Users can control their own security slider within the control panel. System Administrators can customize the security slider during automated installations. As a reminder, in the future, Java 7u51 (January 2014) will block unsigned and self-signed Applets & Web Start applications by default.

Understanding Collabnet’s LDAP binding

- by Robert May

We want to use both subversion usernames and passwords as well as Active Directory for our authentication on our Collabnet subversion server. This has proven to be more of a challenge than we thought, mostly because Collabnet’s documentation is pretty poor. To supplement that documentation, I add my own. The first thing to understand is that the attribute that you specify in the LDAP Login Attribute ONLY applies to lookups done for the user. It does NOT apply to the LDAP Bind DN field. Second, know that the debug logs (error is the one you want) don’t give you debug information for the bind DN, just the login attempts. Third, by default, Active Directory does not allow anonymous binds, so you MUST put in a user that has the authority to query the Active Directory ldap. Because of these items, the values to set in those fields can be somewhat confusing. You’ll want to have ADSI Edit handy (I also used ldp, which is installed by default on server 2008), since ADSI Edit can help you find stuff in your active directory. Be careful, you can also break stuff. Here’s what should go into those fields. LDAP Security Level: Should be set to None LDAP Server Host: Should be set to the full name of a domain controller in your domain. For example, dc.mydomain.com LDAP Server Port: Should be set to 3268. The default port of 389 will only query that specific server, not the global catalog. By setting it to 3268, the global catalog will be queried, which is probably what you want. LDAP Base DN: Should be set to the location where you want the search for users to begin. By default, the search scope is set to sub, so all child organizational units below this setting will be searched. In my case, I had created an OU specifically for users for group policies. My value ended up being: OU=MyOu,DC=domain,DC=org. However, if you’re pointing it to the default Users folder, you may end up with something like CN=Users,DC=domain,DC=org (or com or whatever). Again, use ADSI edit and use the Distinguished Name that it shows. LDAP Bind DN: This needs to be the Distinguished Name of the user that you’re going to use for binding (i.e. the user you’ll be impersonating) for doing queries. In my case, it ended up being CN=svn svn,OU=MyOu,DC=domain,DC=org. Why the double svn, you might ask? That’s because the first and last name fields are set to svn and by default, the distinguished name is the first and last name fields! That’s important. Its NOT the username or account name! Again, use ADSI edit, browse to the username you want to use, right click and select properties, and then search the attributes for the Distinguished Name. Once you’ve found that, select it and click View and you can copy and paste that into this field. LDAP Bind Password: This is the password for the account in the Bind DN LDAP login Attribute: sAMAccountName. If you leave this blank, uid is used, which may not even be set. This tells it to use the Account Name field that’s defined under the account tab for users in Active Directory Users and Computers. Note that this attribute DOES NOT APPLY to the LDAP Bind DN. You must use the full distinguished name of the bind DN. This attribute allows users to type their username and password for authentication, rather than typing their distinguished name, which they probably don’t know. LDAP Search Scope: Probably should stay at sub, but could be different depending on your situation. LDAP Filter: I left mine blank, but you could provide one to limit what you want to see. LDP would be helpful for determining what this is. LDAP Server Certificate Verification: I left it checked, but didn’t try it without it being checked. Hopefully, this will save some others pain when trying to get Collabnet setup. Technorati Tags: Subversion,collabnet

The new Internet Explorer 7 Tax

- by TATWORTH

An Australian online retailer, Kogan, has just announced a 6.8% tax (really a surcharge) on users of IE7. (I wonder how IE6 users would be treated?)To avoid the surcharge, all users have to do is switch to more up to date IE or switch to an alternative browser such as Chrome, Firefox, Opera or Safari.One has to admire the pluck of such a retailer.

Prioritizing Product Features

- by Robert May

A very common task in Agile Environments is prioritization. Teams that are functioning well will prioritize new features, old features, the backlog, and any other source of stories for the team, and they’ll do it regularly. Not all teams are good at prioritizing according to the real return on investment that building stories will yield to the company. This is unfortunate. Too often, teams end up building features that are less valuable, and everyone seems to know it except perhaps the product owner! Most features built into software are never even used. Clearly, not much return for features that go unused. So how does a company avoid building features that add little value to the company? This is a tough question to answer, but usually, this prioritization starts at the top with the executives of the company. After all, they’re responsible for the overall vision of the company. Here’s what I recommend: Know your market. Know your customers and users. Know where you’re going and what you want to achieve. Implement the Vision Know Your Market We often see companies that don’t know their market. Personally, I’m surprised by this. These companies don’t know who their competitors are, don’t know what features make their product desirable in the market, and in many cases, get by with saying, “I’ve been doing this for XX years. I know what the market wants!” In many cases, they equate “marketing” with “advertising” and don’t understand the difference. This is almost never true. Good companies will spend significant amounts of time and money finding out who they’re competing against and what makes their competitors successful in the marketplace. Good companies understand that marketing involves more than just advertising. Often, marketing is mostly research and analysis, not sales. Until you understand your market, you cannot know what features will give you the best return on your investment dollar. Good companies have a marketing department and can answer the next important step which is to know your customers and your users. Know your Customers and Users First, note that I included both customers and users. They’re often not the same thing. Users use the product that you build. Customers buy the product that you build. It’s a subtle difference, but too often, I’ve seen companies that focus exclusively on one or the other and are not successful simply because they ignore an important part of the group. If your company is doing appropriate marketing, you know that these are two different aspects of your product and that both deserve attention to have a product that is successful in your target market. Your marketing department should be spending a lot of time understanding these personas and then conveying that information to the company. I’m always surprised when development teams think that they can build a product that people want to use without understanding the users of that product. Developers think differently than most people in the world. They know what the computer is doing. The computer isn’t magic to them. So when they assume that they know how to build something, they bring with them quite a bit of baggage. Never assume that you know your customer unless you’re regularly having interaction with them. Also, don’t just leave this to Marketing or Product Management. Take them time to get your developers out with the customers as well. Developers are very smart people, and often, seeing how someone uses their software inspires them to make a much better product. Very often, because the users and customers aren’t know, teams will spend a significant amount of time building apps that are super flexible and configurable so that any possible combination of feature can be used. This demonstrates a clear lack of understanding of the customer. Most configuration questions can quickly be answered by talking to the customer. In most cases, if your software requires significant setup and configuration before its usable, you probably don’t know your customers and users very well. Until you know your customers, you cannot know what features will be most valuable to your customers and you cannot build those features in a way that your customers can use. Know Where You’re Going and What You Want to Achieve Many companies suffer from not having a plan. Executives will tell the team to make them a plan. The team, not knowing their market and customers and users, will come up with a plan that doesn’t reflect reality and doesn’t consider ROI. Management then wonders why the product is doing poorly in the market place. Instead of leaving this up to the teams, as executives, work with Marketing to understand what broad categories of features will sell the most product in the marketplace. Then, once you’ve determined that, give this vision to the team and let them run with it. Revise the vision as needed, but avoid changing streams frequently. Sure, sometimes you need to, but often, executives will change priorities many times a month, leading to nothing more than confusion. If the team has a vision, they’ll be able to execute that vision far better than they could otherwise. By knowing what products are most important, you can set budgetary goals and guidelines that will help you achieve the vision that was created. Implement the Vision Creating the vision is often where the general executives stop participating in the plan. The team is responsible for implementing that vision. Executives should attend showcases and and should remain aware of the progress that the team is making towards meeting the vision, however. Once a broad vision has been created, the team should break that vision down into minimal market features (MMF). These MMFs should be sized using story points so that, using the team’s velocity, an estimated cost can be determined for each feature. The product management team should then try to quantify the relative value of the MMFs based on customer feedback and interviews. Once the value and cost of creating the feature is understood, a return on investment can be calculated. The features should then be prioritized with the MMF’s that have the highest value and lowest cost rising to the top of features to implement. Don’t let politics get in the way! Once the MMF’s have been prioritized, they should go through release planning to schedule them for implementation. Conclusion By having a good grasp on the strategy of the company, your Agile teams can be much more effective. Each and every story the team is implementing will roll up into features that matter to the company and provide ROI to them. The steps outlined in this post should be repeated on a regular basis. I recommend reviewing them at least once per quarter to make sure that the vision hasn’t shifted and that the teams are still working on what matters most to the company.

Unable to connect to Samba printer

- by user127236

I have a headless Ubuntu 12.04 server for files and printers. It shares files via Samba just fine. However, the HP PSC-750xi connected to the server via USB is not accessible from my Ubuntu 12.04 laptop.

How do you put price on your source code?

- by deviDave

I was asked to sell the source code of small utility app I did years ago with existing users of this app. I tried investigating how to put price on the source code and haven't come up with a good solution so far. I first tried searching the net, but information I found there are somehow far from reality. Then I found a few people how also sold their source code with users as well. But their price seems unrealistic (too high). For example, one person had an app which price was around $200 for 1 user and he had 80 users. He sold the source with users for $30k. How did he come up with this price? Is it a good price if I charge the code by formula: num_of_users x app_price + app_price x num_of_new_users_in_one_year ? This means that I count the price by selling each user for the price of the app then adding the amount of money I earn in 1 year from this app. If this is a good formula, what shall I do with sources who do not have users yet?

HTG Explains: Do Non-Windows Platforms Like Mac, Android, iOS, and Linux Get Viruses?

- by Chris Hoffman

Viruses and other types of malware seem largely confined to Windows in the real world. Even on a Windows 8 PC, you can still get infected with malware. But how vulnerable are other operating systems to malware? When we say “viruses,” we’re actually talking about malware in general. There’s more to malware than just viruses, although the word virus is often used to talk about malware in general. Why Are All the Viruses For Windows? Not all of the malware out there is for Windows, but most of it is. We’ve tried to cover why Windows has the most viruses in the past. Windows’ popularity is definitely a big factor, but there are other reasons, too. Historically, Windows was never designed for security in the way that UNIX-like platforms were — and every popular operating system that’s not Windows is based on UNIX. Windows also has a culture of installing software by searching the web and downloading it from websites, whereas other platforms have app stores and Linux has centralized software installation from a secure source in the form of its package managers. Do Macs Get Viruses? The vast majority of malware is designed for Windows systems and Macs don’t get Windows malware. While Mac malware is much more rare, Macs are definitely not immune to malware. They can be infected by malware written specifically for Macs, and such malware does exist. At one point, over 650,000 Macs were infected with the Flashback Trojan. [Source] It infected Macs through the Java browser plugin, which is a security nightmare on every platform. Macs no longer include Java by default. Apple also has locked down Macs in other ways. Three things in particular help: Mac App Store: Rather than getting desktop programs from the web and possibly downloading malware, as inexperienced users might on Windows, they can get their applications from a secure place. It’s similar to a smartphone app store or even a Linux package manager. Gatekeeper: Current releases of Mac OS X use Gatekeeper, which only allows programs to run if they’re signed by an approved developer or if they’re from the Mac App Store. This can be disabled by geeks who need to run unsigned software, but it acts as additional protection for typical users. XProtect: Macs also have a built-in technology known as XProtect, or File Quarantine. This feature acts as a blacklist, preventing known-malicious programs from running. It functions similarly to Windows antivirus programs, but works in the background and checks applications you download. Mac malware isn’t coming out nearly as quick as Windows malware, so it’s easier for Apple to keep up. Macs are certainly not immune to all malware, and someone going out of their way to download pirated applications and disable security features may find themselves infected. But Macs are much less at risk of malware in the real world. Android is Vulnerable to Malware, Right? Android malware does exist and companies that produce Android security software would love to sell you their Android antivirus apps. But that isn’t the full picture. By default, Android devices are configured to only install apps from Google Play. They also benefit from antimalware scanning — Google Play itself scans apps for malware. You could disable this protection and go outside Google Play, getting apps from elsewhere (“sideloading”). Google will still help you if you do this, asking if you want to scan your sideloaded apps for malware when you try to install them. In China, where many, many Android devices are in use, there is no Google Play Store. Chinese Android users don’t benefit from Google’s antimalware scanning and have to get their apps from third-party app stores, which may contain infected copies of apps. The majority of Android malware comes from outside Google Play. The scary malware statistics you see primarily include users who get apps from outside Google Play, whether it’s pirating infected apps or acquiring them from untrustworthy app stores. As long as you get your apps from Google Play — or even another secure source, like the Amazon App Store — your Android phone or tablet should be secure. What About iPads and iPhones? Apple’s iOS operating system, used on its iPads, iPhones, and iPod Touches, is more locked down than even Macs and Android devices. iPad and iPhone users are forced to get their apps from Apple’s App Store. Apple is more demanding of developers than Google is — while anyone can upload an app to Google Play and have it available instantly while Google does some automated scanning, getting an app onto Apple’s App Store involves a manual review of that app by an Apple employee. The locked-down environment makes it much more difficult for malware to exist. Even if a malicious application could be installed, it wouldn’t be able to monitor what you typed into your browser and capture your online-banking information without exploiting a deeper system vulnerability. Of course, iOS devices aren’t perfect either. Researchers have proven it’s possible to create malicious apps and sneak them past the app store review process. [Source] However, if a malicious app was discovered, Apple could pull it from the store and immediately uninstall it from all devices. Google and Microsoft have this same ability with Android’s Google Play and Windows Store for new Windows 8-style apps. Does Linux Get Viruses? Malware authors don’t tend to target Linux desktops, as so few average users use them. Linux desktop users are more likely to be geeks that won’t fall for obvious tricks. As with Macs, Linux users get most of their programs from a single place — the package manager — rather than downloading them from websites. Linux also can’t run Windows software natively, so Windows viruses just can’t run. Linux desktop malware is extremely rare, but it does exist. The recent “Hand of Thief” Trojan supports a variety of Linux distributions and desktop environments, running in the background and stealing online banking information. It doesn’t have a good way if infecting Linux systems, though — you’d have to download it from a website or receive it as an email attachment and run the Trojan. [Source] This just confirms how important it is to only run trusted software on any platform, even supposedly secure ones. What About Chromebooks? Chromebooks are locked down laptops that only run the Chrome web browser and some bits around it. We’re not really aware of any form of Chrome OS malware. A Chromebook’s sandbox helps protect it against malware, but it also helps that Chromebooks aren’t very common yet. It would still be possible to infect a Chromebook, if only by tricking a user into installing a malicious browser extension from outside the Chrome web store. The malicious browser extension could run in the background, steal your passwords and online banking credentials, and send it over the web. Such malware could even run on Windows, Mac, and Linux versions of Chrome, but it would appear in the Extensions list, would require the appropriate permissions, and you’d have to agree to install it manually. And Windows RT? Microsoft’s Windows RT only runs desktop programs written by Microsoft. Users can only install “Windows 8-style apps” from the Windows Store. This means that Windows RT devices are as locked down as an iPad — an attacker would have to get a malicious app into the store and trick users into installing it or possibly find a security vulnerability that allowed them to bypass the protection. Malware is definitely at its worst on Windows. This would probably be true even if Windows had a shining security record and a history of being as secure as other operating systems, but you can definitely avoid a lot of malware just by not using Windows. Of course, no platform is a perfect malware-free environment. You should exercise some basic precautions everywhere. Even if malware was eliminated, we’d have to deal with social-engineering attacks like phishing emails asking for credit card numbers. Image Credit: stuartpilbrow on Flickr, Kansir on Flickr

security stuff's

http://fmwdocs.us.oracle.com/doclibs/fmw/E10285_01/appslib7/web.1111/b31974/adding_security.htm#BGBGJEAH At design time, JDeveloper saves all policy store and identity store changes in a single file for the entire application. In the development environment, this is the jazn-data.xml file. After you configure the jazn-data.xml file using the editors, you can run the application in Integrated WebLogic Server and the contents of the policy store will be added to the domain-level store, the system-jazn-data.xml file, while the test users will be migrated to the embedded LDAP server that Integrated WebLogic Server uses for its identity store. The domain-level store allows you to test the security implementation by logging on as test users that you have created. looks like above part did went well with me, apart from following all instruction provided in doc, I need to create users from adminconsole in security-realms-Users and Groups sections to successfully login to pages.

Entity Framework Batch Update and Future Queries

- by pwelter34

Entity Framework Extended Library A library the extends the functionality of Entity Framework. Features Batch Update and Delete Future Queries Audit Log Project Package and Source NuGet Package PM> Install-Package EntityFramework.Extended NuGet: http://nuget.org/List/Packages/EntityFramework.Extended Source: http://github.com/loresoft/EntityFramework.Extended Batch Update and Delete A current limitations of the Entity Framework is that in order to update or delete an entity you have to first retrieve it into memory. Now in most scenarios this is just fine. There are however some senerios where performance would suffer. Also, for single deletes, the object must be retrieved before it can be deleted requiring two calls to the database. Batch update and delete eliminates the need to retrieve and load an entity before modifying it. Deleting //delete all users where FirstName matches context.Users.Delete(u => u.FirstName == "firstname"); Update //update all tasks with status of 1 to status of 2 context.Tasks.Update( t => t.StatusId == 1, t => new Task {StatusId = 2}); //example of using an IQueryable as the filter for the update var users = context.Users .Where(u => u.FirstName == "firstname"); context.Users.Update( users, u => new User {FirstName = "newfirstname"}); Future Queries Build up a list of queries for the data that you need and the first time any of the results are accessed, all the data will retrieved in one round trip to the database server. Reducing the number of trips to the database is a great. Using this feature is as simple as appending .Future() to the end of your queries. To use the Future Queries, make sure to import the EntityFramework.Extensions namespace. Future queries are created with the following extension methods... Future() FutureFirstOrDefault() FutureCount() Sample // build up queries var q1 = db.Users .Where(t => t.EmailAddress == "[email protected]") .Future(); var q2 = db.Tasks .Where(t => t.Summary == "Test") .Future(); // this triggers the loading of all the future queries var users = q1.ToList(); In the example above, there are 2 queries built up, as soon as one of the queries is enumerated, it triggers the batch load of both queries. // base query var q = db.Tasks.Where(t => t.Priority == 2); // get total count var q1 = q.FutureCount(); // get page var q2 = q.Skip(pageIndex).Take(pageSize).Future(); // triggers execute as a batch int total = q1.Value; var tasks = q2.ToList(); In this example, we have a common senerio where you want to page a list of tasks. In order for the GUI to setup the paging control, you need a total count. With Future, we can batch together the queries to get all the data in one database call. Future queries work by creating the appropriate IFutureQuery object that keeps the IQuerable. The IFutureQuery object is then stored in IFutureContext.FutureQueries list. Then, when one of the IFutureQuery objects is enumerated, it calls back to IFutureContext.ExecuteFutureQueries() via the LoadAction delegate. ExecuteFutureQueries builds a batch query from all the stored IFutureQuery objects. Finally, all the IFutureQuery objects are updated with the results from the query. Audit Log The Audit Log feature will capture the changes to entities anytime they are submitted to the database. The Audit Log captures only the entities that are changed and only the properties on those entities that were changed. The before and after values are recorded. AuditLogger.LastAudit is where this information is held and there is a ToXml() method that makes it easy to turn the AuditLog into xml for easy storage. The AuditLog can be customized via attributes on the entities or via a Fluent Configuration API. Fluent Configuration // config audit when your application is starting up... var auditConfiguration = AuditConfiguration.Default; auditConfiguration.IncludeRelationships = true; auditConfiguration.LoadRelationships = true; auditConfiguration.DefaultAuditable = true; // customize the audit for Task entity auditConfiguration.IsAuditable<Task>() .NotAudited(t => t.TaskExtended) .FormatWith(t => t.Status, v => FormatStatus(v)); // set the display member when status is a foreign key auditConfiguration.IsAuditable<Status>() .DisplayMember(t => t.Name); Create an Audit Log var db = new TrackerContext(); var audit = db.BeginAudit(); // make some updates ... db.SaveChanges(); var log = audit.LastLog;

Active Directory Password Policy Problem

- by Will

To Clarify: my question is why isn't my password policy applying to people in the domain. Hey guys, having trouble with our password policy in Active Directory. Sometimes it just helps me to type out what I’m seeing It appears to not be applying properly across the board. I am new to this environment and AD in general but I think I have a general grasp of what should be going on. It’s a pretty simple AD setup without too many Group Policies being applied. It looks something like this DOMAIN Default Domain Policy (link enabled) Password Policy (link enabled and enforce) Personal OU Force Password Change (completely empty nothing in this GPO) IT OU Lockout Policy (link enabled and enforced) CS OU Lockout Policy Accouting OU Lockout Policy The password policy and default domain policy both define the same things under Computer ConfigWindows seetings sec settings Account Policies / Password Policy Enforce password History : 24 passwords remembered Maximum Password age : 180 days Min password age: 14 days Minimum Password Length: 6 characters Password must meet complexity requirements: Enabled Store Passwords using reversible encryption: Disabled Account Policies / Account Lockout Policy Account Lockout Duration 10080 Minutes Account Lockout Threshold: 5 invalid login attempts Reset Account Lockout Counter after : 30 minutes IT lockout This just sets the screen saver settings to lock computers when the user is Idle. After running Group Policy modeling it seems like the password policy and default domain policy is getting applied to everyone. Here is the results of group policy modeling on MO-BLANCKM using the mblanck account, as you can see the policies are both being applied , with nothing important being denied Group Policy Results NCLGS\mblanck on NCLGS\MO-BLANCKM Data collected on: 12/29/2010 11:29:44 AM Summary Computer Configuration Summary General Computer name NCLGS\MO-BLANCKM Domain NCLGS.local Site Default-First-Site-Name Last time Group Policy was processed 12/29/2010 10:17:58 AM Group Policy Objects Applied GPOs Name Link Location Revision Default Domain Policy NCLGS.local AD (15), Sysvol (15) WSUS-52010 NCLGS.local/WSUS/Clients AD (54), Sysvol (54) Password Policy NCLGS.local AD (58), Sysvol (58) Denied GPOs Name Link Location Reason Denied Local Group Policy Local Empty Security Group Membership when Group Policy was applied BUILTIN\Administrators Everyone S-1-5-21-507921405-1326574676-682003330-1003 BUILTIN\Users NT AUTHORITY\NETWORK NT AUTHORITY\Authenticated Users NCLGS\MO-BLANCKM$ NCLGS\Admin-ComputerAccounts-GP NCLGS\Domain Computers WMI Filters Name Value Reference GPO(s) None Component Status Component Name Status Last Process Time Group Policy Infrastructure Success 12/29/2010 10:17:59 AM EFS recovery Success (no data) 10/28/2010 9:10:34 AM Registry Success 10/28/2010 9:10:32 AM Security Success 10/28/2010 9:10:34 AM User Configuration Summary General User name NCLGS\mblanck Domain NCLGS.local Last time Group Policy was processed 12/29/2010 11:28:56 AM Group Policy Objects Applied GPOs Name Link Location Revision Default Domain Policy NCLGS.local AD (7), Sysvol (7) IT-Lockout NCLGS.local/Personal/CS AD (11), Sysvol (11) Password Policy NCLGS.local AD (5), Sysvol (5) Denied GPOs Name Link Location Reason Denied Local Group Policy Local Empty Force Password Change NCLGS.local/Personal Empty Security Group Membership when Group Policy was applied NCLGS\Domain Users Everyone BUILTIN\Administrators BUILTIN\Users NT AUTHORITY\INTERACTIVE NT AUTHORITY\Authenticated Users LOCAL NCLGS\MissingSkidEmail NCLGS\Customer_Service NCLGS\Email_Archive NCLGS\Job Ticket Users NCLGS\Office Staff NCLGS\CUSTOMER SERVI-1 NCLGS\Prestige_Jobs_Email NCLGS\Telecommuters NCLGS\Everyone - NCL WMI Filters Name Value Reference GPO(s) None Component Status Component Name Status Last Process Time Group Policy Infrastructure Success 12/29/2010 11:28:56 AM Registry Success 12/20/2010 12:05:51 PM Scripts Success 10/13/2010 10:38:40 AM Computer Configuration Windows Settings Security Settings Account Policies/Password Policy Policy Setting Winning GPO Enforce password history 24 passwords remembered Password Policy Maximum password age 180 days Password Policy Minimum password age 14 days Password Policy Minimum password length 6 characters Password Policy Password must meet complexity requirements Enabled Password Policy Store passwords using reversible encryption Disabled Password Policy Account Policies/Account Lockout Policy Policy Setting Winning GPO Account lockout duration 10080 minutes Password Policy Account lockout threshold 5 invalid logon attempts Password Policy Reset account lockout counter after 30 minutes Password Policy Local Policies/Security Options Network Security Policy Setting Winning GPO Network security: Force logoff when logon hours expire Enabled Default Domain Policy Public Key Policies/Autoenrollment Settings Policy Setting Winning GPO Enroll certificates automatically Enabled [Default setting] Renew expired certificates, update pending certificates, and remove revoked certificates Disabled Update certificates that use certificate templates Disabled Public Key Policies/Encrypting File System Properties Winning GPO [Default setting] Policy Setting Allow users to encrypt files using Encrypting File System (EFS) Enabled Certificates Issued To Issued By Expiration Date Intended Purposes Winning GPO SBurns SBurns 12/13/2007 5:24:30 PM File Recovery Default Domain Policy For additional information about individual settings, launch Group Policy Object Editor.
