• Second query to SQLite (on iPhone) errors.

  - by Luke

  Hi all, On the iPhone, I am developing a class for a cart that connects directly to a database. To view the cart, all items can be pulled from the database, however, it seems that removing them doesn't work. It is surprising to me because the error occurs during connection to the database, except not the second time I connect even after the DB has been closed. #import "CartDB.h" #import "CartItem.h" @implementation CartDB @synthesize database, databasePath; - (NSMutableArray *) getAllItems { NSMutableArray *items = [[NSMutableArray alloc] init]; if([self openDatabase]) { const char *sqlStatement = "SELECT * FROM items;"; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(cartDatabase, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while(sqlite3_step(compiledStatement) == SQLITE_ROW) { int rowId = sqlite3_column_int(compiledStatement, 0); int productId = sqlite3_column_int(compiledStatement, 1); NSString *features = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; int quantity = sqlite3_column_int(compiledStatement, 3); CartItem *cartItem = [[CartItem alloc] initWithRowId:rowId productId:productId features:features quantity:quantity]; [items addObject:cartItem]; [cartItem release]; } } sqlite3_finalize(compiledStatement); } [self closeDatabase]; return items; } - (BOOL) removeCartItem:(CartItem *)item { sqlite3_stmt *deleteStatement; [self openDatabase]; const char *sql = "DELETE FROM items WHERE id = ?"; if(sqlite3_prepare_v2(cartDatabase, sql, -1, &deleteStatement, NULL) != SQLITE_OK) { return NO; } sqlite3_bind_int(deleteStatement, 1, item.rowId); if(SQLITE_DONE != sqlite3_step(deleteStatement)) { sqlite3_reset(deleteStatement); [self closeDatabase]; return NO; } else { sqlite3_reset(deleteStatement); [self closeDatabase]; return YES; } } - (BOOL) openDatabase { if(sqlite3_open([databasePath UTF8String], &cartDatabase) == SQLITE_OK) { return YES; } else { return NO; } } - (void) closeDatabase { sqlite3_close(cartDatabase); } The error occurs on the line where the connection is opened in openDatabase. Any ideas? Need to flush something? Something gets autoreleased? I really can't figure it out. --Edit-- The error that I receive is GDB: Program received signal "EXC_BAD_ACCESS". --Edit-- I ended up just connecting in the init and closing in the free methods, which might not be the proper way, but that's another question altogether so it's effectively persistent instead of connecting multiple times. Still would be nice to know what was up with this for future reference.

• Running two wsgi applications on the same server gdal org exception with apache2/modwsgi

  - by monkut

  I'm trying to run two wsgi applications, one django and the other tilestache using the same server. The tilestache server accesses the db via django to query the db. In the process of serving tiles it performs a transform on the incoming bbox, and in this process hit's the following error. The transform works without error for the specific bbox polygon when run manually from the python shell: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 325, in __call__ mimetype, content = requestHandler(self.config, environ['PATH_INFO'], environ['QUERY_STRING']) File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 231, in requestHandler mimetype, content = getTile(layer, coord, extension) File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 84, in getTile tile = layer.render(coord, format) File "/usr/lib/python2.7/dist-packages/TileStache/Core.py", line 295, in render tile = provider.renderArea(width, height, srs, xmin, ymin, xmax, ymax, coord.zoom) File "/var/www/tileserver/providers.py", line 59, in renderArea bbox.transform(METERS_SRID) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/geos/geometry.py", line 520, in transform g = gdal.OGRGeometry(self.wkb, srid) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geometries.py", line 131, in __init__ self.__class__ = GEO_CLASSES[self.geom_type.num] File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geometries.py", line 245, in geom_type return OGRGeomType(capi.get_geom_type(self.ptr)) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geomtype.py", line 43, in __init__ raise OGRException('Invalid OGR Integer Type: %d' % type_input) OGRException: Invalid OGR Integer Type: 1987180391 I think I've hit the non thread safe issue with GDAL, metioned on the django site. Is there a way I could configure this so that it would work? Apache Version: Apache/2.2.22 (Ubuntu) mod_wsgi/3.3 Python/2.7.3 configured Apache apache2/sites-available/default: <VirtualHost *:80> ServerAdmin ironman@localhost DocumentRoot /var/www/bin LogLevel warn WSGIDaemonProcess lbs processes=2 maximum-requests=500 threads=1 WSGIProcessGroup lbs WSGIScriptAlias / /var/www/bin/apache/django.wsgi Alias /static /var/www/lbs/static/ </VirtualHost> <VirtualHost *:8080> ServerAdmin ironman@localhost DocumentRoot /var/www/bin LogLevel warn WSGIDaemonProcess tilestache processes=1 maximum-requests=500 threads=1 WSGIProcessGroup tilestache WSGIScriptAlias / /var/www/bin/tileserver/tilestache.wsgi </VirtualHost> Django Version: 1.4 httpd.conf: Listen 8080 NameVirtualHost *:8080 UPDATE I've added the a test.wsgi script to determine if the GLOBAL interpreter setting is correct, as mentioned by graham and described here: http://code.google.com/p/modwsgi/wiki/CheckingYourInstallation#Sub_Interpreter_Being_Used It seems to show the expected result: [Tue Aug 14 10:32:01 2012] [notice] Apache/2.2.22 (Ubuntu) mod_wsgi/3.3 Python/2.7.3 configured -- resuming normal operations [Tue Aug 14 10:32:01 2012] [info] mod_wsgi (pid=29891): Attach interpreter ''. I've worked around the issue for now by changing the srs used in the db so that the transform is unnecessary in tilestache app. I don't understand why the transform() method, when called in the django app works, but then in the tilestache app fails. tilestache.wsgi #!/usr/bin/python import os import time import sys import TileStache current_dir = os.path.abspath(os.path.dirname(__file__)) project_dir = os.path.realpath(os.path.join(current_dir, "..", "..")) sys.path.append(project_dir) sys.path.append(current_dir) os.environ['DJANGO_SETTINGS_MODULE'] = 'bin.settings' sys.stdout = sys.stderr # wait for the apache django lbs server to start up, # --> in order to retrieve the tilestache cfg time.sleep(2) tilestache_config_url = "http://127.0.0.1/tilestache/config/" application = TileStache.WSGITileServer(tilestache_config_url) UPDATE 2 So it turned out I did need to use a projection other than the google (900913) one in the db. So my previous workaround failed. While I'd like to fix this issue, I decided to work around the issue this type by making a django view that performs the transform needed. So now tilestache requests the data through the django app and not internally.

• How can I work around problems with certificate configuration in Remote Desktop Services?

  - by Michael Steele

  I am setting up a Remote Desktop Services farm, and am having trouble configuring certificates for it to use. A demonstration of the problem I'm seeing can be found in Step #4. At this point I am convinced that there are problems with the user interface, and am looking for ways around them. Is there any way to configure certificates in Remote Desktop Services so that the settings hold and are reflected in the GUI? If not, is there any way for me to verify that the settings are correct? Step #1 - Create certificate to be used. I've configured a certificate to use with RD Web Access. The certificate is stored with in the Certificates MMC on my RD Connection Broker, and I am configuring the farm from that computer. I found by letting RD Web Access generate its own certificate that the following properties are required: Enhanced Key Usage Server Authentication Client Authentication This may not be required, but the self-signed certificate includes it. Key Usage Digital Signature Key Agreement Subject Alternative Name DNS Name=domain.com Detour about self-signed certificate generation As a quick detour, I was able to work around a problem with creating self-signed certificates using powershell. The documentation for the New-RDCertificate cmdlet gives the following example: PS C:\> $password = ConvertTo-SecureString -string "password" -asplaintext -force New-RDCertificate -Role RDWebAccess -DnsName "test-rdwa.contoso.com" -Password $password -ConnectionBroker rdcb.contoso.com -ExportPath "c:\test-rdwa.pfx" Typing this into the shell will result in an error message claiming that a function, Get-Server cannot be found. Prior to using New-RDCertificate, you must import the RemoteDesktop Module with Import-Module RemoteDesktop. Step #2 - Observe out-of-box behavior The first time you visit the Deployment Properties dialog box by navigating to Server Manager - Remote Desktop Services - Collections and selecting "Edit Deployment Properties" from the "TASKS" dropdown list in the "COLLECTIONS" grouping, you will see the following screen: This window is misleading because the level field is listed as "Not Configured". If I understand correctly all three of the role services are using a self-signed certificate. For the RD Web Access role this can be verified by visiting the website: The certificate being used also appears in the Certificates MMC: Step #3 - Assign new certificate The Deployment Properties dialog box will allow me to select my existing certificate. The certificate must be placed within the local computers Certificates MMC in the "Personal" certificate store. The private key will need to be exportable, and you will need to provide the password. I temporarily exported my certificate to a file named temp.pfx with a password, and then imported it into Remote Desktop Services from there. Once this is done the GUI will indicate that it is ready to accept the new configuration. Once I click the "Apply" button, the GUI indicates success. This can be verified by visiting the RD Web Access web site a second time. There is no certificate error. Step #4 - The GUI fails to maintain its state If the GUI is closed and reopened, all of these settings appear to be lost. Actually, the certificate I configured is still being used. I am able to continue accessing the RD Web Access site without any certificate errors. Oddly, if I use the "Create new certificate..." button to generate a self-signed certificate this window will update to an "Untrusted" level. This setting will then be maintained through the opening and closing of the Deployment Properties dialog box. Is there anything I can do to have my settings appear to stick? I feel like something is wrong when the GUI claims I haven't fully configured certificates.

• Take,Skip and Reverse Operator in Linq

  - by Jalpesh P. Vadgama

  I have found three more new operators in Linq which is use full in day to day programming stuff. Take,Skip and Reverse. Here are explanation of operators how it works. Take Operator: Take operator will return first N number of element from entities. Skip Operator: Skip operator will skip N number of element from entities and then return remaining elements as a result. Reverse Operator: As name suggest it will reverse order of elements of entities. Here is the examples of operators where i have taken simple string array to demonstrate that. C#, using GeSHi 1.0.8.6 using System; using System.Collections.Generic; using System.Linq; using System.Text;     namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {             string[] a = { "a", "b", "c", "d" };                           Console.WriteLine("Take Example");             var TkResult = a.Take(2);             foreach (string s in TkResult)             {                 Console.WriteLine(s);             }               Console.WriteLine("Skip Example");             var SkResult = a.Skip(2);             foreach (string s in SkResult)             {                 Console.WriteLine(s);             }               Console.WriteLine("Reverse Example");             var RvResult = a.Reverse();             foreach (string s in RvResult)             {                 Console.WriteLine(s);             }                       }     } } Parsed in 0.020 seconds at 44.65 KB/s Here is the output as expected. hope this will help you..

• WCF RIA Services DomainContext Abstraction Strategies–Say That 10 Times!

  - by dwahlin

  The DomainContext available with WCF RIA Services provides a lot of functionality that can help track object state and handle making calls from a Silverlight client to a DomainService. One of the questions I get quite often in our Silverlight training classes (and see often in various forums and other areas) is how the DomainContext can be abstracted out of ViewModel classes when using the MVVM pattern in Silverlight applications. It’s not something that’s super obvious at first especially if you don’t work with delegates a lot, but it can definitely be done. There are various techniques and strategies that can be used but I thought I’d share some of the core techniques I find useful. To start, let’s assume you have the following ViewModel class (this is from my Silverlight Firestarter talk available to watch online here if you’re interested in getting started with WCF RIA Services): public class AdminViewModel : ViewModelBase { BookClubContext _Context = new BookClubContext(); public AdminViewModel() { if (!DesignerProperties.IsInDesignTool) { LoadBooks(); } } private void LoadBooks() { _Context.Load(_Context.GetBooksQuery(), LoadBooksCallback, null); } private void LoadBooksCallback(LoadOperation<Book> books) { Books = new ObservableCollection<Book>(books.Entities); } } Notice that BookClubContext is being used directly in the ViewModel class. There’s nothing wrong with that of course, but if other ViewModel objects need to load books then code would be duplicated across classes. Plus, the ViewModel has direct knowledge of how to load data and I like to make it more loosely-coupled. To do this I create what I call a “Service Agent” class. This class is responsible for getting data from the DomainService and returning it to a ViewModel. It only knows how to get and return data but doesn’t know how data should be stored and isn’t used with data binding operations. An example of a simple ServiceAgent class is shown next. Notice that I’m using the Action<T> delegate to handle callbacks from the ServiceAgent to the ViewModel object. Because LoadBooks accepts an Action<ObservableCollection<Book>>, the callback method in the ViewModel must accept ObservableCollection<Book> as a parameter. The callback is initiated by calling the Invoke method exposed by Action<T>: public class ServiceAgent { BookClubContext _Context = new BookClubContext(); public void LoadBooks(Action<ObservableCollection<Book>> callback) { _Context.Load(_Context.GetBooksQuery(), LoadBooksCallback, callback); } public void LoadBooksCallback(LoadOperation<Book> lo) { //Check for errors of course...keeping this brief var books = new ObservableCollection<Book>(lo.Entities); var action = (Action<ObservableCollection<Book>>)lo.UserState; action.Invoke(books); } } This can be simplified by taking advantage of lambda expressions. Notice that in the following code I don’t have a separate callback method and don’t have to worry about passing any user state or casting any user state (the user state is the 3rd parameter in the _Context.Load method call shown above). public class ServiceAgent { BookClubContext _Context = new BookClubContext(); public void LoadBooks(Action<ObservableCollection<Book>> callback) { _Context.Load(_Context.GetBooksQuery(), (lo) => { var books = new ObservableCollection<Book>(lo.Entities); callback.Invoke(books); }, null); } } A ViewModel class can then call into the ServiceAgent to retrieve books yet never know anything about the DomainContext object or even know how data is loaded behind the scenes: public class AdminViewModel : ViewModelBase { ServiceAgent _ServiceAgent = new ServiceAgent(); public AdminViewModel() { if (!DesignerProperties.IsInDesignTool) { LoadBooks(); } } private void LoadBooks() { _ServiceAgent.LoadBooks(LoadBooksCallback); } private void LoadBooksCallback(ObservableCollection<Book> books) { Books = books } } You could also handle the LoadBooksCallback method using a lambda if you wanted to minimize code just like I did earlier with the LoadBooks method in the ServiceAgent class.  If you’re into Dependency Injection (DI), you could create an interface for the ServiceAgent type, reference it in the ViewModel and then inject in the object to use at runtime. There are certainly other techniques and strategies that can be used, but the code shown here provides an introductory look at the topic that should help get you started abstracting the DomainContext out of your ViewModel classes when using WCF RIA Services in Silverlight applications.

• OSI Model

  - by kaleidoscope

  The Open System Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model. A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. Description of OSI layers: Layer 1: Physical Layer ·         Defines the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a physical medium. ·         Establishment and termination of a connection to a communications medium. ·         Participation in the process whereby the communication resources are effectively shared among multiple users. ·         Modulation or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a communications channel. Layer 2: Data Link Layer ·         Provides the functional and procedural means to transfer data between network entities. ·         Detect and possibly correct errors that may occur in the Physical Layer. The error check is performed using Frame Check Sequence (FCS). ·         Addresses is then sought to see if it needs to process the rest of the frame itself or whether to pass it on to another host. ·         The Layer is divided into two sub layers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. ·         MAC sub layer controls how a computer on the network gains access to the data and permission to transmit it. ·         LLC layer controls frame synchronization, flow control and error checking.   Layer 3: Network Layer ·         Provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks. ·         Performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors. ·         Network Layer Routers operate at this layer—sending data throughout the extended network and making the Internet possible.   Layer 4: Transport Layer ·         Provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. ·         Controls the reliability of a given link through flow control, segmentation/de-segmentation, and error control. ·         Transport Layer can keep track of the segments and retransmit those that fail. Layer 5: Session Layer ·         Controls the dialogues (connections) between computers. ·         Establishes, manages and terminates the connections between the local and remote application. ·         Provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. ·         Implemented explicitly in application environments that use remote procedure calls. Layer 6: Presentation Layer ·         Establishes a context between Application Layer entities, in which the higher-layer entities can use different syntax and semantics, as long as the presentation service understands both and the mapping between them. The presentation service data units are then encapsulated into Session Protocol data units, and moved down the stack. ·         Provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer. Layer 7: Application Layer ·         This layer interacts with software applications that implement a communicating component. ·         Identifies communication partners, determines resource availability, and synchronizes communication. o       When identifying communication partners, the application layer determines the identity and availability of communication partners for an application with data to transmit. o       When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists. o       In synchronizing communication, all communication between applications requires cooperation that is managed by the application layer.

• What I've Gained from being a Presenter at Tech Events

  - by MOSSLover

  Originally posted on: http://geekswithblogs.net/MOSSLover/archive/2014/06/12/what-ive-gained-from-being-a-presenter-at-tech-events.aspxI know I fail at blogging lately.  As I've said before life happens and it gets in the way of best laid out plans.  I thought about creating some type of watch with some app that basically dictates using dragon naturally speaking to Wordpress, but alas no time and the write processing capabilities just don't exist yet.So to get to my point Alison Gianotto created this blog post: http://www.snipe.net/2014/06/why-you-should-stop-stalling-and-start-presenting/.  I like the message she has stated in this post and I want to share something personal.It was around 2007 that I was seriously looking into leaving the technology field altogether and going back to school.  I was calling places like Washington University in Saint Louis and University of Missouri Kansas City asking them how I could go about getting into some type of post graduate medical school program.  My entire high school career was based on Medical Explorers and somehow becoming a doctor.  I did not want to take my hobby and continue using it as a career mechanism.  I was unhappy, but I didn't realize why I was unhappy at the time.  It was really a lot of bad things involving the lack of self confidence and self esteem.  Overall I was not in a good place and it took me until 2011 to realize that I still was not in a good place in life.So in about April 2007 or so I started this blog that you guys have been reading or occasionally read.  I kind of started passively stalking people by reading their blogs in the SharePoint and .Net communities.  I also started listening to .Net Rocks & watching videos on their corresponding training for SharePoint, WCF, WF, and a bunch of other technologies.  I wanted more knowledge, so someone suggested I go to a user group.  I've told this story before about how I met Jeff Julian & John Alexander, so that point I will spare you the details.  You know how I got to my first user group presentation and how I started getting involved with events, so I'll also spare those details.The point I want to touch on is that I went out I started speaking and that path I took helped me gain the self confidence and self respect I needed.  When I first moved to NYC I couldn't even ride a subway by myself or walk alone without getting lost.  Now I feel like I can go out and solve any problem someone throws at me.  So you see what Alison states in her blog post is true and I am a great example to that point.  I stood in front of 800 or so people at SharePoint Conference in 2011 and spoke about a topic.  In 2007 I would have hidden or stuttered the entire time.  I have now spoken at over 70 events and user groups.  I am a top 25 influencer in my technology.  I was a most valued professional for years in a row in Microsoft SharePoint.  People are constantly trying to gain my time, so that they can pick my brain for solutions and other life problems.  I went from maybe five or six friends to over hundreds of friends in various cities across the globe.  I'm not saying it's an instant fame and it doesn't take a ton of work, but I have never looked back once at my life and regretted the choice I made in 2007.  It has lead me to a lot of other things in my life, including more positivity and happiness.  If anyone ever wants to contact me and pick my brain on a presentation go ahead.  If you want me to help you find the best meetup that suits you for that presentation I can try to help too (I might be a little more helpful in the Microsoft or iOS arenas though).  The best thing I can state is don't be scared just do it.  If you need an audience I can try to pencil it in my schedule.  I can't promise anything, but if you are in NYC I can at least try.

• What is the best Broadphase Interface for moving spheres?

  - by Molmasepic

• Oracle Announces Release of PeopleSoft HCM 9.1 Feature Pack 2

  - by Jay Zuckert

  Big things sometimes come in small packages.  Today Oracle announced the availability of PeopleSoft HCM 9.1 Feature Pack 2 which delivers a new HR self service user experience that fundamentally changes the way managers and employees interact with the HCM system.  Earlier this year we reviewed a number of new concept designs with our Customer Advisory Boards.  With the accelerated feature pack development cycle we have adopted, these innovations are  now available to all 9.1 customers without the need for an upgrade.   There are no new products that need to be licensed for the capabilities below. For more details on Feature Pack 2, please see the Oracle press release. Included in Feature Pack 2 is a new search-based menu-free navigation that allows managers to search for employees by name and take actions directly from the secure search results.  For example, a manager can now simply type in part of an employee’s first or last name and receive meaningful results from documents related to performance, compensation, learning, recruiting, career planning and more.   Delivered actions can be initiated directly from these search results and the actions are securely tied to HCM security and user role.  The feature pack also includes new pages that will enable managers to be more productive by aggregating key employee data into a single page.  The new Manager Dashboard and Talent Summary provide a consolidated view of data related to a manager’s team and individual team members, respectively.   The Manager Dashboard displays information relevant to their direct reports including team learning, objective alignment, alerts, and pending approvals requiring their attention.  The Talent Summary provides managers with an aggregated view of talent management-related data for an individual employee including performance history, salary history, succession options, total rewards, and competencies.   The information displayed in both the Manager Dashboard and Talent Summary is configurable by system administrators and can be personalized by each of your managers. Other Feature Pack 2 enhancements allow organizations to administer Matrix or Dotted-Line Relationship Management, which addresses the challenge of tracking and maintaining project-based organizations that cut across the enterprise and geographic regions.  From within the Company Directory and Org Viewer organization charts, managers now have access to manager self-service transactions from related actions.  More than 70 manager and employee self-service transactions have been tied into the related action framework accessible from Org Viewer, Manager Dashboard, Talent Summary and Secure Enterprise Search (SES) results.  In addition to making it easier to access manager self-service transactions, the feature pack delivers streamlined transaction pages making everyday tasks such as promoting an employee faster and more efficient. With the delivery of PeopleSoft HCM 9.1 Feature Pack 2, Oracle continues to deliver on its commitment to our PeopleSoft customers.  With this feature pack, HCM 9.1 customers will be able to deploy the newest functionality quickly, without a major release upgrade, and realize added value from their existing PeopleSoft investment.    For customers newly deploying 9.1, a new download with all of Feature Pack 2  will be available early next year.   This will aslo include recertified upgrade paths from 8.8, 8.9 and 9.0, for customers in the upgrade process.

• The Connected Company: WebCenter Portal - Feedback - Analytics and Polls

  - by Michael Snow

  Evernote Export body, td { }Guest Post by: Mitchell Palski, Staff Sales Consultant The importance of connecting peers has been widely recognized and socialized as a critical component of employee intranets. Organizations are striving to provide mediums for sharing knowledge and improving awareness across their enterprise. Indirectly, the socialization of your enterprise should lead to cost savings and improved product/service quality. However, many times the direct effects of connecting an organization’s leadership with its employees are overlooked. Oracle WebCenter Portal can help you bridge that gap by gathering implicit and explicit feedback. Implicit Feedback Through Usage Analytics Analytics allows administrators to track and analyze WebCenter Portal traffic and usage. Analytics provides the following basic functionality: Usage Tracking Metrics: Analytics collects and reports metrics of common WebCenter Portal functions, including community and portlet traffic. Behavior Tracking: Analytics can be used to analyze WebCenter Portal metrics to determine usage patterns, such as page visit duration and usage over time. User Profile Correlation: Analytics can be used to correlate metric information with user profile information. Usage tracking reports can be viewed and filtered by user profile data such as country, company or title. Usage analytics help measure how users interact with website content – allowing your IT staff and business analysts to make informed decisions when planning development for your next intranet enhancement. For example: If users are not accessing your Announcements page and missing critical information that they need to be aware of, you may elect to use graphical links on the home page to direct more users to that page. As a result, the number of employee help-requests to HR decreases. If users are not accessing your News page to read recent articles, you may elect to stop spending as much time updating the page with new stories and cut costs in your communications department. You notice that there is a high volume of users accessing the Employee Dashboard page so your organization decides to continue making personalization enhancements to the page and investing in the Portal tool that most users are accessing. Usage analytics aren’t necessarily a new concept in the IT industry. What sets WebCenter Portal Analytics apart is: Reports are tailored for WebCenter specific tools Report can be easily added to a page as simple as a drag-and-drop Explicit Feedback Through Polls WebCenter Portal users can create, edit, take, and analyze online polls. With polls, you can survey your audience (such as their opinions and their experience level), check whether they can recall important information, and gather feedback and metrics. How many times have you been involved in a requirements discussion and someone has asked a question similar to “Well how do you know that no one likes our home page?” and the response is “Everyone says they hate it! That’s all anyone complains about.” No one has any measurable, quantifiable metric to gauge user satisfaction. Analytics measure usage, but your organization also needs to measure the quality of your portal as defined by the actual people that use it. With that information, your leadership can make informed decisions that will not only match usage patterns but also relate to employees on a personal level. The end result is a connection between employees and leadership that gives everyone in the organization a sense of ownership of their Portal rather than the feeling of development decisions being segregated to leadership only. Polls can be created and edited through the Poll Manager: Polls and View Poll Results can easily be added to a page through drag-and-drop. What did we learn? Being a “connected” company doesn’t just mean helping employees connect with each other horizontally across your enterprise. It also means connecting those employees to the decisions that affect their everyday activities. Through WebCenter Portal Usage Analytics and Polls, any decision that is made to remove a Portal page, update a Portal page, or develop new Portal functionality, can be justified by quantifiable metrics. Instead of fielding complaints and hearing that your employees don’t have a voice, give those employees a voice and listen!

• Using Content Analytics for More Effective Engagement

  - by Kellsey Ruppel

  Using Content Analytics for More Effective Engagement: Turning High-Volume Content into Templates for Success By Mitchell Palski, Oracle WebCenter Sales Consultant Many organizations use Oracle WebCenter Portal to develop these basic types of portals: Intranet portals used for collaboration, employee self-service, and company communication Extranet portals used by customers and partners for self-service and support Team collaboration portals that allow users to share documents and content, track activity, and engage in discussions Portals are intended to provide a personalized, single point of interaction with web-based applications and information. The user experiences that a Portal is capable of displaying should be relevant to an individual user or class of users (a group or role). The components of a Portal that would vary based on a user’s identity include: Web content such as images, news articles, and on-screen instruction Social tools such as threaded discussions, polls/surveys, and blogs Document management tools to upload, download, and edit files Web applications that present data visualizations and data entry modules These collections of content, tools, and applications make up valuable workspaces. The challenge that a development team may have is defining which combinations are the most effective for its users. No one wants to create and manage a workspace that goes un-used or (even worse) that is used but is ineffective. Oracle WebCenter Portal provides you with the capabilities to not only rapidly develop variations of portals, but also identify which portals are the most effective and should be re-used throughout an enterprise. Capturing Portal AnalyticsOracle WebCenter Portal provides an analytics service that allows administrators and business users to track and analyze portal usage. These analytics are captured in the form of: Usage tracking metrics Behavior tracking User Profile Correlation The out-of-the-box task reports that come with Oracle WebCenter Portal include: WebCenter Portal Traffic Page Traffic Login Metrics Portlet Traffic Portlet Response Time Portlet Instance Traffic Portlet Instance Response Time Search Metrics Document Metrics Wiki Metrics Blog Metrics Discussion Metrics Portal Traffic Portal Response Time By determining the usage and behavior tracking metrics that are associated with specific user profiles (including groups and roles), your administrators will be able to identify the components of your solution that are the most valuable.  Your first step as an administrator should be to identify the specific pages and/or components are used the most frequently. Next, determine the user(s) or user-group(s) that are accessing those high-use elements of a portal. It is also important to determine patterns in high-usage and see if they correlate to a specific schedule. One of the goals of any development team (especially those that are following Agile methodologies) should be to develop reusable web components to minimize redundant development. Oracle WebCenter Portal provides you the tools to capture the successful workspaces that have already been developed and identified so that they can be reused for similar user demographics. Re-using Successful PortalsWhen creating a new Portal in Oracle WebCenter, developers have the option to base that portal on a template that includes: Pre-seeded data such as pages, tools, user roles, and look-and-feel assets Specific sub-sets of page-layouts, tools, and other resources to standardize what is added to a Portal’s pages Any custom components that your team creates during development cycles Once you have identified a successful workspace and its most valuable components, leverage Oracle WebCenter’s ability to turn that custom portal into a portal template. By creating a template from your already successful portal, you are empowering your enterprise by providing a starting point for future initiatives. Your new projects, new teams, and new web pages can benefit from lessons learned and adjustments that have already been made to optimize user experiences instead of starting from scratch. ***For a complete explanation of how to work with Portal Templates, be sure to read the Fusion Middleware documentation available online.

• I.T. Chargeback : Core to Cloud Computing

  - by Anand Akela

  Contributed by Mark McGill Consolidation and Virtualization have been widely adopted over the years to help deliver benefits such as increased server utilization, greater agility and lower cost to the I.T. organization. These are key enablers of cloud, but in themselves they do not provide a complete cloud solution. Building a true enterprise private cloud involves moving from an admin driven world, where the I.T. department is ultimately responsible for the provisioning of servers, databases, middleware and applications, to a world where the consumers of I.T. resources can provision their infrastructure, platforms and even complete application stacks on demand. Switching from an admin-driven provisioning model to a user-driven model creates some challenges. How do you ensure that users provisioning resources will not provision more than they need? How do you encourage users to return resources when they have finished with them so that others can use them? While chargeback has existed as a concept for many years (especially in mainframe environments), it is the move to this self-service model that has created a need for a new breed of chargeback applications for cloud. Enabling self-service without some form of chargeback is like opening a shop where all of the goods are free. A successful chargeback solution will be able to allocate the costs of shared I.T. infrastructure based on the relative consumption by the users. Doing this creates transparency between the I.T. department and the consumers of I.T. When users are able to understand how their consumption translates to cost they are much more likely to be prudent when it comes to their use of I.T. resources. This also gives them control of their I.T. costs, as moderate usage will translate to a lower charge at the end of the month. Implementing Chargeback successfully create a win-win situation for I.T. and the consumers. Chargeback can help to ensure that I.T. resources are used for activities that deliver business value. It also improves the overall utilization of I.T. infrastructure as I.T. resources that are not needed are not left running idle. Enterprise Manager 12c provides an integrated metering and chargeback solution for Enterprise Manager Targets. This solution is built on top of the rich configuration and utilization information already available in Enterprise Manager. It provides metering not just for virtual machines, but also for physical hosts, databases and middleware. Enterprise Manager 12c provides metering based on the utilization and configuration of the following types of Enterprise Manager Target: Oracle VM Host Oracle Database Oracle WebLogic Server Using Enterprise Manager Chargeback, administrators are able to create a set of Charge Plans that are used to attach prices to the various metered resources. These plans can contain fixed costs (eg. $10/month/database), configuration based costs (eg. $10/month if OS is Windows) and utilization based costs (eg. $0.05/GB of Memory/hour) The self-service user provisioning these resources is then able to view a report that details their usage and helps them understand how this usage translates into cost. Armed with this information, the user is able to determine if the resources are delivering adequate business value based on what is being charged. Figure 1: Chargeback in Self-Service Portal Enterprise Manager 12c provides a variety of additional interfaces into this data. The administrator can access summary and trending reports. Summary reports allow the administrator to drill-down through the cost center hierarchy to identify, for example, the top resource consumers across the organization. Figure 2: Charge Summary Report Trending reports can be used for I.T. planning and budgeting as they show utilization and charge trends over a period of time. Figure 3: CPU Trend Report We also provide chargeback reports through BI Publisher. This provides a way for users who do not have an Enterprise Manager login (such as Line of Business managers) to view charge and usage information. For situations where a bill needs to be produced, chargeback can be integrated with billing applications such as Oracle Billing and Revenue Management (BRM).

• iPhone SDK 3.2 UIGestureRecognizer interfering with UIView animations?

  - by Brian Cooley

  Are there known issues with gesture recognizers and the UIView class methods for animation? I am having problems with a sequence of animations on a UIImageView from UIGestureRecognizer callback. If the sequence of animations is started from a standard callback like TouchUpInside, the animation works fine. If it is started via the UILongPressGestureRecognizer, then the first animation jumps to the end and the second animation immediately begins. Here's a sample that illustrates my problem. In the .xib for the project, I have a UIImageView that is connected to the viewToMove IBOutlet. I also have a UIButton connected to the startButton IBOutlet, and I have connected its TouchUpInside action to the startButtonClicked IBAction. The TouchUpInside action works as I want it to, but the longPressGestureRecognizer skips to the end of the first animation after about half a second. When I NSLog the second animation (animateTo200) I can see that it is called twice when a long press starts the animation but only once when the button's TouchUpInside action starts the animation. - (void)viewDidLoad { [super viewDidLoad]; UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(startButtonClicked)]; NSArray *recognizerArray = [[NSArray alloc] initWithObjects:longPressRecognizer, nil]; [startButton setGestureRecognizers:recognizerArray]; [longPressRecognizer release]; [recognizerArray release]; } -(IBAction)startButtonClicked { if (viewToMove.center.x < 150) { [self animateTo200:@"Right to left" finished:nil context:nil]; } else { [self animateTo100:@"Right to left" finished:nil context:nil]; } } -(void)animateTo100:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Right to left" context:nil]; [UIView setAnimationDuration:4]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animateTo200:finished:context:)]; viewToMove.center = CGPointMake(100.0, 100.0); [UIView commitAnimations]; } -(void)animateTo200:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Left to right" context:nil]; [UIView setAnimationDuration:4]; viewToMove.center = CGPointMake(200.0, 200.0); [UIView commitAnimations]; }

• Customizing Django form widgets? - Django

  - by RadiantHex

  Hi folks, I'm having a little problem here! I have discovered the following as being the globally accepted method for customizing Django admin field. from django import forms from django.utils.safestring import mark_safe class AdminImageWidget(forms.FileInput): """ A ImageField Widget for admin that shows a thumbnail.

• Subclassing UINavigationBar ... how do I use it in UINavigationController?

  - by funkadelic

  Hi, I wanted to subclass UINavigationBar (to set a custom background image & text color) and use that for all the navigation bars in my app. Looking at the API docs for UINavigationController, it looks like navigationBar is read-only: @property(nonatomic, readonly) UINavigationBar *navigationBar Is there a way to actually use a custom UINavigationBar in my UIViewControllers? I know that other apps have done custom navigation bars, like flickr: Here is my UINavigationBar subclass: #import <UIKit/UIKit.h> @interface MyNavigationBar : UINavigationBar <UINavigationBarDelegate> { } @end the implementation #import "MyNavigationBar.h" @implementation MyNavigationBar - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // override the standard background with our own custom one UIImage *image = [[UIImage imageNamed:@"navigation_bar_bgd.png"] retain]; [image drawInRect:rect]; [image release]; } #pragma mark - #pragma mark UINavigationDelegate Methods - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ // use the title of the passed in view controller NSString *title = [viewController title]; // create our own UILabel with custom color, text, etc UILabel *titleView = [[UILabel alloc] init]; [titleView setFont:[UIFont boldSystemFontOfSize:18]]; [titleView setTextColor:[UIColor blackColor]]; titleView.text = title; titleView.backgroundColor = [UIColor clearColor]; [titleView sizeToFit]; viewController.navigationItem.titleView = titleView; [titleView release]; viewController.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.1 green:0.2 blue:0.3 alpha:0.8]; } - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ } - (void)dealloc { [super dealloc]; } @end I know that I can use a category to change the background image, but i still want to be able to set the text color of the navigation bar title @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"navigation_bar_bgd.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end any suggestions or other solutions? I basically want to create a light background and dark text like Flickr's app navigation bars

• Core Data: Keypath "objectID" not found in entity

  - by Martin Gordon

  I'm using NSFetchedResultsController with a predicate to load a list of Documents in my application. I want to load all the Documents except the currently active one. I am using Rentzsch's MOGenerator to create a _Document class and then I put all my custom code in the Document subclass. _Document generates an objectID property with type DocumentID. In the class that creates the controller, I set the controller's currentDocID property: controller.currentDocID = self.document.objectID; In the controller itself, I lazy load the fetchedResultsController like this: - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Document" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(objectID != %@)", self.currentDocID]; [fetchRequest setPredicate:predicate]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"dateModified" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [sortDescriptor release]; [sortDescriptors release]; return fetchedResultsController; } When the fetchedResultsController loads, my app crashes with an unhandled exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath objectID not found in entity <NSSQLEntity Document id=1>' It's my understanding that all NSManagedObjects have an objectID, whether temporary or permanent. Is this not the case? Any thoughts?

• How load WebView with another URL when navigated through tab bar viewController

  - by TechFusion

  Hello, I have created window based application, root controller as Tab bar controller. WebView is being loaded in Tab bar interfaced ViewController's View.WebView is created using IB.WebView object declared in ViewController as per below. //ViewController.h @interface ViewController:UIViewController{ IBOutlet UIWebview *Webview; } @property(nonatomic,retain)IBOutlet UIWebview *Webview; @end I am calling [WebView loadrequest] method in -viewDidLoad method and stopLoading will be called in -viewWillDisappear method. I am again reload it in -viewWillAppear:animated method to load it again when tab bar is pressed. //ViewController.m @implementation viewcontroller @synthesize Webview; -(void)viewDidLoad{ [super viewDidLoad]; [self.Webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"www.apple.com"]]]; } -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.Webview reload]; } -(void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; [self.Webview stopLoading]; } I am releasing WebView in -ViewDidUnload method -(void)viewDidUnload{ [super viewDidUnload]; [Webview release]; } -(void)dealloc{ [Webview release]; [super dealloc]; } Does Webview released correctly ? Here how to kill connection with URL when ViewWillDisappear method called ? How to load View with Different URL then it's loaded in -viewDidLoad method when ViewController interfaced tab is pressed ? Means if naviagated from one tab to another that ViewController interface tab which has WebView should load request with another URL. Does it correct to call [self.Webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"www.stackoverflow.com"]]]; this method again in -viewWillAppear:animated method to load with another URL ? Thanks,

• Failed to set the initialPlaybackTime for a MPMoviePlayerController when recreating it in the second

  - by vicky

  Hi, everyone. It's really wired. When at the first time a MPMoviePlayerController (e.g., theMovie) is created, its initialPlaybackTime can be set successfully. But when theMoive is released and re-create a new MPMoviePlayerController, its intialPlaybackTime can not be set correctly, actually the movie always plays from the start. The code is as follows. -(void)initAndPlayMovie:(NSURL *)movieURL { MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; // create a notification for moviePlaybackFinish [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie]; theMovie.initialPlaybackTime = 15; [theMovie setScalingMode:MPMovieScalingModeAspectFill]; [theMovie play];} -(void) moviePlayBackDidFinish:(NSNotification*)notification { MPMoviePlayerController * theMovie = [notification object]; [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:theMovie]; [theMovie release]; [self initAndPlayMovie:[self getMovieURL]]; } With the above code, when the viewcontroller did load and run initAndPlayMovie, the movie starts to play from 15 seconds, but when it plays finished or "Done" is pushed, a new theMovie is created and starts to play from 0 second. Does anybody know what happened with the initialPlaybackTime property of MPMoviePlayerController? And whenever you reload the viewController where the above code is (presentModalViewController from a parent viewcontroller), the movie can start from any playback time. I am really confused what's the difference of the MPMoviePlayerController registration methods between the viewcontroller load and the recreating it after release. Need your help! Thank you!

• little more help with a CATiledLayer

  - by Brodie4598

  Okay so I am trying to adapt an online tutorial for CATiledLayer to use in my app. The example uses a PDF but I need to display a JPG. I'm getting close, but I just cant figure this out. Should I be using a UIImage or something else? #import <QuartzCore/QuartzCore.h> #import "practiceViewController.h" @implementation practiceViewController - (void)viewDidLoad { [super viewDidLoad]; NSBundle *bundle = [[NSBundle mainBundle]autorelease]; NSString *path = [bundle pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, 1600, 2400); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1024.0, 1024.0); tiledLayer.levelsOfDetail = 1000; tiledLayer.levelsOfDetailBias = 1000; tiledLayer.frame = pageRect; myContentView = [[UIView alloc] initWithFrame:pageRect]; [myContentView.layer addSublayer:tiledLayer]; CGRect viewFrame = self.view.frame; viewFrame.origin = CGPointZero; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:viewFrame]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.maximumZoomScale = 1000; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NEED HE:LP WITH THIS } @end

• TTStyledTextLabel offset between link and regular text when changing from default font

  - by Guy Ephraim

  I'm using Three20 TTStyledTextLabel and when I change the default font (Helvetica) to something else it creates some kind of height difference between links and regular text The following code demonstrate my problem: #import <Three20/Three20.h> @interface TestController : UIViewController { } @end @implementation TestController -(id)init{ self = [super init]; TTStyledTextLabel* label = [[[TTStyledTextLabel alloc] initWithFrame:CGRectMake(0, 0, 320, 230)] autorelease]; label.text = [TTStyledText textFromXHTML:@"<a href=\"aa://link1\">link</a> text" lineBreaks:YES URLs:YES]; [label setFont:[UIFont systemFontOfSize:16]]; [[self view] addSubview:label]; TTStyledTextLabel* label2 = [[[TTStyledTextLabel alloc] initWithFrame:CGRectMake(0, 230, 320, 230)] autorelease]; label2.text = [TTStyledText textFromXHTML:@"<a href=\"aa://link1\">link2</a> text2" lineBreaks:YES URLs:YES]; [label2 setFont:[UIFont fontWithName:@"HelveticaNeue" size:16]]; [[self view] addSubview:label2]; return self; } @end In the screen shot you can see that the first link is aligned and the second one isn't How do I fix it? I think there is a bug in the TTStyledTextLabel code...
