• Cannot connect to website - SSL handshaking fails

  - by ravenspoint

  So I cannot connect to certain websites. Just a few, most are OK. The one I really care about is paypal.com. I have done the usual things. Let's see: Checked my etc/hosts Flushed the DNS cache Checked firewall Switched on & off virus protection Switched on and off ad blocking pinged the sites Eventually, I decided to look at what curl is saying in detail == Info: About to connect() to www.paypal.com port 443 (#0) == Info: Trying 66.211.169.2... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 110 bytes (0x6e) 0000: 01 00 00 6a 03 01 4f 6c aa 8c 57 2b 3d 1e 74 64 ...j..Ol..W+=.td 0010: c1 27 25 a5 3a 12 7f 3f 41 0a 17 15 2e c9 67 7c .'%.:.?A.....g| 0020: b3 e1 f6 9a db a9 00 00 2a 00 39 00 38 00 35 00 ........*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 17 00 00 00 13 00 11 00 00 0e ................ 0060: 77 77 77 2e 70 61 79 70 61 6c 2e 63 6f 6d www.paypal.com (hangs here for ever) This looks to me like paypal is refusing to reply to the first SSL handshake. I don't know much about SSL, but compaing to the output from a site that works for me seems to make it obvious == Info: About to connect() to www.cibc.com port 443 (#0) == Info: Trying 159.231.80.200... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 108 bytes (0x6c) 0000: 01 00 00 68 03 01 4f 6c ad 6a 1f 67 d5 84 c4 4b ...h..Ol.j.g...K 0010: 0d 49 ae d6 b9 5b c3 63 f9 48 aa 18 da 43 d1 32 .I...[.c.H...C.2 0020: 47 ae 17 e5 cd e9 00 00 2a 00 39 00 38 00 35 00 G.......*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 15 00 00 00 11 00 0f 00 00 0c ................ 0060: 77 77 77 2e 63 69 62 63 2e 63 6f 6d www.cibc.com == Info: SSLv3, TLS handshake, Server hello (2): <= Recv SSL data, 74 bytes (0x4a) 0000: 02 00 00 46 03 01 00 00 58 cf 26 e2 e1 65 db 11 ...F....X.&..e.. 0010: bc 6f 26 7b 3b 6d eb 14 5f ad 47 dd 86 ea 4d a3 .o&{;m.._.G...M. 0020: fb 9f b7 2a 54 3e 20 5f 6b 04 5a 12 38 64 5d 18 ...*T> _k.Z.8d]. 0030: 65 9e e9 cd 61 eb 91 c1 16 25 61 30 bb 08 2a 78 e...a....%a0..*x 0040: b8 ee b8 7e f2 65 6a 00 04 00 ...~.ej... == Info: SSLv3, TLS handshake, CERT (11): ... and so on - working nicely eventually get some nice HTML Now I am reaaly stuck. This has been going on for five days, so I am pretty sure that the problem is not with paypal. But what on my system could be interfering with the SSL handshaking done by curl with this particular site? I suppose I could not be offering any certificates that PayPal accepts, but wouldn't I get a reply telling me so, or at least giving an error?

• ActiveMQ AJax Client

  - by Lily

  I try to write a simple Ajax client to send and receive messages. It's successfully deployed but I have never received msg from the client. I am beating myself to think out what I am missing, but still can't make it work. Here is my code: I creat a dynamic web application named: ActiveMQAjaxService and put activemq-web.jar and all neccessary dependencies in the WEB-INF/lib folder. In this way, AjaxServlet and MessageServlet will be deployed I start activemq server in command line: ./activemq = activemq successfully created and display: Listening for connections at: tcp://lilyubuntu:61616 INFO | Connector openwire Started INFO | ActiveMQ JMS Message Broker (localhost, ID:lilyubuntu-56855-1272317001405-0:0) started INFO | Logging to org.slf4j.impl.JCLLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog INFO | jetty-6.1.9 INFO | ActiveMQ WebConsole initialized.

I can run the demo portfolioPublisher demo successfully at http://localhost:8161/demo/portfolio/portfolio.html, and see the numbers updated all the time. But for my simple web-app, nothing really works. Any suggestion/hint is welcomed. Thanks so much Lily

• Asynchrony in C# 5: Dataflow Async Logger Sample

  - by javarg

  Check out this (very simple) code examples for TPL Dataflow. Suppose you are developing an Async Logger to register application events to different sinks or log writers. The logger architecture would be as follow: Note how blocks can be composed to achieved desired behavior. The BufferBlock<T> is the pool of log entries to be process whereas linked ActionBlock<TInput> represent the log writers or sinks. The previous composition would allows only one ActionBlock to consume entries at a time. Implementation code would be something similar to (add reference to System.Threading.Tasks.Dataflow.dll in %User Documents%\Microsoft Visual Studio Async CTP\Documentation): TPL Dataflow Logger var bufferBlock = new BufferBlock<Tuple<LogLevel, string>>(); ActionBlock<Tuple<LogLevel, string>> infoLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Info: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> errorLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Error: {0}", e.Item2)); bufferBlock.LinkTo(infoLogger, e => (e.Item1 & LogLevel.Info) != LogLevel.None); bufferBlock.LinkTo(errorLogger, e => (e.Item1 & LogLevel.Error) != LogLevel.None); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Info, "info message")); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Error, "error message")); Note the filter applied to each link (in this case, the Logging Level selects the writer used). We can specify message filters using Predicate functions on each link. Now, the previous sample is useless for a Logger since Logging Level is not exclusive (thus, several writers could be used to process a single message). Let´s use a Broadcast<T> buffer instead of a BufferBlock<T>. Broadcast Logger var bufferBlock = new BroadcastBlock<Tuple<LogLevel, string>>(     e => new Tuple<LogLevel, string>(e.Item1, e.Item2)); ActionBlock<Tuple<LogLevel, string>> infoLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Info: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> errorLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Error: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> allLogger =     new ActionBlock<Tuple<LogLevel, string>>(     e => Console.WriteLine("All: {0}", e.Item2)); bufferBlock.LinkTo(infoLogger, e => (e.Item1 & LogLevel.Info) != LogLevel.None); bufferBlock.LinkTo(errorLogger, e => (e.Item1 & LogLevel.Error) != LogLevel.None); bufferBlock.LinkTo(allLogger, e => (e.Item1 & LogLevel.All) != LogLevel.None); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Info, "info message")); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Error, "error message")); As this block copies the message to all its outputs, we need to define the copy function in the block constructor. In this case we create a new Tuple, but you can always use the Identity function if passing the same reference to every output. Try both scenarios and compare the results.

• Custom Templates: Using user exits

  - by Anthony Shorten

  One of the features of Oracle Utilities Application Framework V4.1 is the ability to use templates and user exits to extend the base configuration files. The configuration files used by the product are based upon a set of templates shipped with the product. When the configureEnv utility asks for configuration settings they are stored in a configuration file ENVIRON.INI which outlines the environment settings. These settings are then used by the initialSetup utility to populate the various configuration files used by the product using templates located in the templates directory of the installation. Now, whilst the majority of the installations at any site are non-production and the templates provided are generally adequate for that need, there are circumstances where extension of templates are needed to take advantage of more advanced facilities (such as advanced security and environment settings). The issue then becomes that if you alter the configuration files manually (directly or indirectly) then you may lose all your custom settings the next time you run initialSetup. To counter this we allow customers to either override templates with their own template or we now provide user exits in the templates to add fragments of configuration unique to that part of the configuration file. The latter means that the base template is still used but additions are included to provide the extensions. The provision of custom templates is supported but as soon as you use a custom template you are then responsible for reflecting any changes we put in the base template over time. Not a big task but annoying if you have to do it for multiple copies of the product. I prefer to use user exits as they seem to represent the least effort solution. The way to find the user exits available is to either read the Server Administration Guide that comes with your product or look at individual templates and look for the lines: #ouaf_user_exit <user exit name> Where <user exit name> is the name of the user exit. User exits are not always present but are in places that we feel are the most likely to be changed. If a user exit does not exist the you can always use a custom template instead. Now lets show an example. By default, the product generates a config.xml file to be used with Oracle WebLogic. This configuration file has the basic setting contained in it to manage the product. If you want to take advantage of the Oracle WebLogic advanced settings, you can use the console to make those changes and it will be reflected in the config.xml automatically. To retain those changes across invocations of initialSetup, you need to alter the template that generates the config.xml or use user exits. The technique is this. Make the change in the console and when you save the change, WebLogic will reflect it in the config.xml for you. Compare the old version and new version of the config.xml and determine what to add and then find the user exit to put it in by examining the base template. For example, by default, the console is not automatically deployed (it is deployed on demand) in the base config.xml. To make the console deploy, you can add the following line to the templates/CM_config.xml.win.exit_3.include file (for windows) or templates/CM_config.xml.exit_3.include file (for linux/unix): <internal-apps-deploy-on-demand-enabled>false</internal-apps-deploy-on-demand-enabled> Now run initialSetup to reflect the change and if you check the splapp/config/config.xml file you will see the change applied for you. Now how did I know which include file? I check the template for config.xml and found there was an user exit at the right place. I prefixed my include filename with "CM_" to denote it as a custom user exit. This will tell the upgrade tools to leave that file alone whenever you decide to upgrade (or even apply fixes). User exits can be powerful and allow customizations to be added for advanced configuration. You will see products using Oracle Utilities Application Framework use this exits themselves (usually prefixed with the product code). You are also taking advantage of them.

• Booting the liveCD/USB in EFI mode fails on Samsung Tablet XE700T1A

  - by F.L.

  My tablet is Samsung Series 7 Slate (XE700T1A-A02FR (French Language)). It operates an Intel Sandy Bridge architecture. The main issue about this tablet is that it ships with an installed Windows 7 in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu. But it seems I can't boot on the liveCD in EFI mode. It starts loading (up to initrd), but I then get a blank (black) screen. I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. [2012-09-27] I have used the Ubuntu 12.04.1 Desktop ISO (I have read somewhere that it is the only one that can boot in EFI mode). I'd say this has something to do with UEFI since the LiveCD boots in bios mode but not in efi mode. Besides, I am not sure my boot info will help, since I can't boot the LiveCD in EFI mode. As a result I can't install ubuntu in EFI mode. So it would be the boot info from the liveCD boot in bios mode. This happens on a ubuntu-12.04.1-desktop-amd64 iso used on a LiveUSB. Live USB was created by dd'ing the iso onto the full disk device (i.e. /dev/sdx no number) of the Flash drive. I have also tried copying the LiveCD files on a primary GPT partition, but with no luck, I just get the grub shell, no menu, no install option. [2012-09-28] I tried today a flash drive created with Ubuntu's Startup Disk Creator and the alternate 12.04.1 64 bit ISO. I get a grub menu in text mode (which meens it did start in efi mode) with install options / test options. But when I start any of these, I simply get a black screen (no cursor, neither mouse nor text-mode cursor). I tried removing the 'quiet' option and adding nomodeset and acpi=off, but it didn't do any good. So this is the same result as for the LiveCD. [2012-10-01] I have tried with a version of the secure remix version via usb-creator-gtk. The boot on the USB key has the same symptoms. Boot in EFI mode is impossible (I have menu but whatever entry I choose, I get the blank screen problem). The boot in BIOS mode works, I did the install. Then I used boot-repair to try installing grub-efi and get a system that would boot in efi mode. But I can't boot this system, because the EFI firmware doesn't seem to detect that sda contains a valid efi partition. Here is the resulting boot-info Boot info 1253554 [2012-10-01] Today, I have reinstalled the pre-shipped version of windows 7, and then installed ubuntu from a secure-remix iso dumped on USB flash drive vie usb-creator-gtk booted in BIOS mode. When install ended, I said "continue testing" then I used boot-repair to try get the bootloader installed. Now, when I boot the tablet, I get the grub menu, it can chainload windows 7 flawlessly. But when I try to start one of the ubuntu options I get the same old blank screen. Here is the new boot-info: Boot info 1253927 [2012-10-01] I tried installing the 3.3 kernel by chrooting a live usb boot (secure remix again) into the installed system. Same symptoms. I feel the key to this is that the device's efi firmware (which is EFI v2.0) would expose the graphics hardware in a way that prevents the kernel to initialize it, and thus prevents it from booting (the kernel stops all drive access just after the screen turns kind of very dark purple). Here is some info on the UEFI firmware as given by rEFInd: EFI revision: 2.00 Platform: x86_64 (64 bit) Firmware: American Megatrends 4.635 Screen Output: Graphics Output (UEFI), 800x600 [2012-10-08] This week end I tried loading the kernel with elilo. Eventhough I didn't have more luck on booting the kernel, elilo gives more info when loading the kernel. I think the next step is trying to load a kernel with EFI stub directly.

• Perspective Is Everything

  - by juanlarios

  Sitting on a window seat on my way back from Seattle I looked out the window and saw the large body of water. I was reminded of childhood memories of running as hard as I could through burning hot sand with the anticipation of the splash of the ocean. Looking out the window the water appeared like a sheet draped over land. I couldn’t help but ponder how perspective changes everything.  Over the last several days I had a chance to attend the MVP Summit in Redmond. I had a great time with fellow MVP’s and the SharePoint Product Group. Although I can’t say much about what was discussed and what is coming in the future, I want to share some realizations I had while experiencing the MVP summit.  The SharePoint Product is ever-improving, full of innovation but also a reactionary embodiment of MVP, client and market feedback. There are several features that come to mind that clients complain about where I have felt helpless in informing them that the features are not as mature as they would like it. Together, we figure out a way to make it work and deal with the limitations. It became clear that there are features that have taken a different purpose in the market place from the original vision. The SP Product group is working hard to react to these changes in vision and make SharePoint better for real life implementations.  It is easy to think that SharePoint should be all things to all people. In reality there are products that are very detailed in specific composites, they do this one thing well but severely lack in other areas.  Its easy sometimes to say, “What was Microsoft thinking with this feature?” the Product group is doing all they can to make the moving pieces better and dealing with challenges with having all of them work together.  Sometimes the features don’t fully embody the vision because of the many challenges, but trust me when I say the product group is really focused on delivery and innovation.  As I was speaking with a fellow MVP throughout the session, we spoke about the iPad 2(ironically announced this past week during the MVP summit) and Microsoft’s possible product answer; I realized the days of reactionary products from MS is over. There are many users that will remember Vista and the painful execution in that product, but there has been a lot of success in Windows 7. There was no rush for a reactionary answer to the Nintendo Wii, as a result a ground breaking and game changing product was brought to market, the XBOX –Kinect! I can’t say much here, but it’s safe to say, expect innovation, and execution of products and technology that will change the market instead of react to them!       There are many things I learned and I would love to share that have to do with perspective, technology, etc… but this is far as I can go in details. This might not be new to you or specifically the message that was shared during the summit. These are just my impressions of the event and the spirit of future vision. Great things ahead!

  I have One Server (Srv1) which holds data with file shares and the storage is full. Now I have second Server (Srv2) which has alot more space. No I would like to transfer all the data von Serv1 to Serv2 and have links to the new destination. I found mklink very useful here but unfortunately it does not work over the network. Which also points the docu out. People heavily rely on the path's so it would be helpful if somone has a pointer for me... how to handle symbolic links a cross the network with Windows Servers. I am running Windows Server 2008. Thanks for any help

• Framework 4 Features: Summary of Security enhancements

  - by Anthony Shorten

  In the last log entry I mentioned one of the new security features in Oracle Utilities Application Framework 4.0.1. Security is one of the major "tent poles" (to borrow a phrase from Steve Jobs) in this release of the framework. There are a number of security related enhancements requested by customers and as a result of internal reviews that we have introduced. Here is a summary of some of the security enchancements we have added in this release: Security Cache Changes - Security authorization information is automatically cached on the server for performance reasons (security is checked for every single call the product makes for all modes of access). Prior to this release the cache auto-refreshed every 30 minutes (or so). This has beem made more nimble by supporting a cache refresh every minute (or so). This means authorization changes are reflected quicker than before. Business Level security - Business Services are configurable services that are based upon Application Services. Typically, the business service inherited its security profile from its parent service. Whilst this is sufficient for most needs, it is now required to further specify security on the Business Service definition itself. This will allow granular security and allow the same application service to be exposed as different Business Services with their own security. This is particularly useful when you base a Business Service on a query zone. User Propogation - As with other client server applications, the database connections are pooled and shared as needed. This means that a common database user is used to access the database from the pool to allow sharing. Unfortunently, this means that tracability at the database level is that much harder. In Oracle Utilities Application Framework V4 the end userid is now propogated to the database using the CLIENT_IDENTIFIER as part of the Oracle JDBC connection API. This not only means that the common database userid is still used but the end user is indentifiable for the duration of the database call. This can be used for monitoring or to hook into Oracle's database security products. This enhancement is only available to Oracle Database customers. Enhanced Security Definitions - Security Administrators use the product browser front end to control access rights of defined users. While this is sufficient for most sites, a new security portal has been introduced to speed up the maintenance of security information. Oracle Identity Manager Integration - With the popularity of Oracle's Identity Management Suite, the Framework now provides an integration adapter and Identity Manager Generic Transport Connector (GTC) to allow users and group membership to be provisioned to any Oracle Utilities Application Framework based product from Oracle's Identity Manager. This is also available for Oracle Utilties Application Framework V2.2 customers. Refer to My Oracle Support KBid 970785.1 - Oracle Identity Manager Integration Overview. Audit On Inquiry - Typically the configurable audit facility in the Oracle Utilities Application Framework is used to audit changes to records. In Oracle Utilities Application Framework the Business Services and Service Scripts could be configured to audit inquiries as well. Now it is possible to attach auditing capabilities to zones on the product (including base package ones). Time Zone Support - In some of the Oracle Utilities Application Framework based products, the timezone of the end user is a factor in the processing. The user object has been extended to allow the recording of time zone information for use in product functionality. JAAS Suport - Internally the Oracle Utilities Application Framework uses a number of techniques to validate and transmit security information across the architecture. These various methods have been reconciled into using Java Authentication and Authorization Services for standardized security. This is strictly an internal change with no direct on how security operates externally. JMX Based Cache Management - In the last bullet point, I mentioned extra security applied to cache management from the browser. Alternatively a JMX based interface is now provided to allow IT operations to control the cache without the browser interface. This JMX capability can be initiated from a JSR120 compliant JMX console or JMX browser. I will be writing another more detailed blog entry on the JMX enhancements as it is quite a change and an exciting direction for the product line. Data Patch Permissions - The database installer provided with the product required lower levels of security for some operations. At some sites they wanted the ability for non-DBA's to execute the utilities in a controlled fashion. The framework now allows feature configuration to allow delegation for patch execution. User Enable Support - At some sites, the use of temporary staff such as contractors is commonplace. In this scenario, temporary security setups were required and used. A potential issue has arisen when the contractor left the company. Typically the IT group would remove the contractor from the security repository to prevent login using that contractors userid but the userid could NOT be removed from the authorization model becuase of audit requirements (if any user in the product updates financials or key data their userid is recorded for audit purposes). It is now possible to effectively diable the user from the security model to prevent any use of the useridwhilst retaining audit information. These are a subset of the security changes in Oracle Utilities Application Framework. More details about the security capabilities of the product is contained in My Oracle Support KB Id 773473.1 - Oracle Utilities Application Framework Security Overview.

• Implementing an Interceptor Using NHibernate’s Built In Dynamic Proxy Generator

  - by Ricardo Peres

  NHibernate 3.2 came with an included proxy generator, which means there is no longer the need – or the possibility, for that matter – to choose Castle DynamicProxy, LinFu or Spring. This is actually a good thing, because it means one less assembly to deploy. Apparently, this generator was based, at least partially, on LinFu. As there are not many tutorials out there demonstrating it’s usage, here’s one, for demonstrating one of the most requested features: implementing INotifyPropertyChanged. This interceptor, of course, will still feature all of NHibernate’s functionalities that you are used to, such as lazy loading, and such. We will start by implementing an NHibernate interceptor, by inheriting from the base class NHibernate.EmptyInterceptor. This class does not do anything by itself, but it allows us to plug in behavior by overriding some of its methods, in this case, Instantiate: 1: public class NotifyPropertyChangedInterceptor : EmptyInterceptor 2: { 3: private ISession session = null; 4:  5: private static readonly ProxyFactory factory = new ProxyFactory(); 6:  7: public override void SetSession(ISession session) 8: { 9: this.session = session; 10: base.SetSession(session); 11: } 12:  13: public override Object Instantiate(String clazz, EntityMode entityMode, Object id) 14: { 15: Type entityType = Type.GetType(clazz); 16: IProxy proxy = factory.CreateProxy(entityType, new _NotifyPropertyChangedInterceptor(), typeof(INotifyPropertyChanged)) as IProxy; 17: 18: _NotifyPropertyChangedInterceptor interceptor = proxy.Interceptor as _NotifyPropertyChangedInterceptor; 19: interceptor.Proxy = this.session.SessionFactory.GetClassMetadata(entityType).Instantiate(id, entityMode); 20:  21: this.session.SessionFactory.GetClassMetadata(entityType).SetIdentifier(proxy, id, entityMode); 22:  23: return (proxy); 24: } 25: } Then we need a class that implements the NHibernate dynamic proxy behavior, let’s place it inside our interceptor, because it will only need to be used there: 1: class _NotifyPropertyChangedInterceptor : NHibernate.Proxy.DynamicProxy.IInterceptor 2: { 3: private PropertyChangedEventHandler changed = delegate { }; 4:  5: public Object Proxy 6: { 7: get; 8: set;} 9:  10: #region IInterceptor Members 11:  12: public Object Intercept(InvocationInfo info) 13: { 14: Boolean isSetter = info.TargetMethod.Name.StartsWith("set_") == true; 15: Object result = null; 16:  17: if (info.TargetMethod.Name == "add_PropertyChanged") 18: { 19: PropertyChangedEventHandler propertyChangedEventHandler = info.Arguments[0] as PropertyChangedEventHandler; 20: this.changed += propertyChangedEventHandler; 21: } 22: else if (info.TargetMethod.Name == "remove_PropertyChanged") 23: { 24: PropertyChangedEventHandler propertyChangedEventHandler = info.Arguments[0] as PropertyChangedEventHandler; 25: this.changed -= propertyChangedEventHandler; 26: } 27: else 28: { 29: result = info.TargetMethod.Invoke(this.Proxy, info.Arguments); 30: } 31:  32: if (isSetter == true) 33: { 34: String propertyName = info.TargetMethod.Name.Substring("set_".Length); 35: this.changed(this.Proxy, new PropertyChangedEventArgs(propertyName)); 36: } 37:  38: return (result); 39: } 40:  41: #endregion 42: } What this does for every interceptable method (those who are either virtual or from the INotifyPropertyChanged) is: For methods that came from the INotifyPropertyChanged interface, add_PropertyChanged and remove_PropertyChanged (yes, events are methods ), we add an implementation that adds or removes the event handlers to the delegate which we declared as changed; For all the others, we direct them to the place where they are actually implemented, which is the Proxy field; If the call is setting a property, it fires afterwards the PropertyChanged event. In order to use this, we need to add the interceptor to the Configuration before building the ISessionFactory: 1: using (ISessionFactory factory = cfg.SetInterceptor(new NotifyPropertyChangedInterceptor()).BuildSessionFactory()) 2: { 3: using (ISession session = factory.OpenSession()) 4: using (ITransaction tx = session.BeginTransaction()) 5: { 6: Customer customer = session.Get<Customer>(100); //some id 7: INotifyPropertyChanged inpc = customer as INotifyPropertyChanged; 8: inpc.PropertyChanged += delegate(Object sender, PropertyChangedEventArgs e) 9: { 10: //fired when a property changes 11: }; 12: customer.Address = "some other address"; //will raise PropertyChanged 13: customer.RecentOrders.ToList(); //will trigger the lazy loading 14: } 15: } Any problems, questions, do drop me a line!

• Adventures in Scrum: Lesson 1 &ndash; The failed Sprint

  - by Martin Hinshelwood

  I recently had a conversation with a product owner that wanted to have the Scrum team broken up into smaller units so that less time was wasted on the Scrum Ceremonies! Their complaint was around the need in Scrum to have the entire “Team” (7+-2) involved in the sizing of the work during the “Sprint Planning Meeting”.  The standard flippant answer of all Scrum professionals, “Well that's not Scrum”, does not get you any brownie points in these situations. The response could be “Well we are not doing Scrum then” which in turn leads to “We are doing Scrum…But, we have split the scrum team into units of 2/3 so that they can concentrate on a specific area of work”. While this may work, it is not Scrum and should not be called so… It is just a form of Agile. Don’t get me wrong at this stage, there is nothing wrong with Agile, just don’t call it Scrum. The reason that the Product Owner wants to do this is that, in effect, through a number of miscommunications and failings in our implementation of Scrum, there was NO unit of potentially Shippable software at the end of the first sprint. It does not matter to them that most Scrum teams will fail the first Sprint, even those that are high performing teams. Remember it is the product owners their money! We should NOT break up scrum teams into smaller units for the purpose of having less people tied up in the Scrum Ceremonies. The amount of backlog the Team selects is solely up to the Team… Only the Team can assess what it can accomplish over the upcoming Sprint. - Scrum Guide, Scrum.org The entire team must accept the work and in order to understand what they can accept they must be free to size it as a team. This both encourages common understanding and increases visibility on why team members think a task is of a particular size. This has the benefit of increasing the knowledge of the entire team in the problem domain. A new Team often first realizes that it will either sink or swim as a Team, not individually, in this meeting. The Team realizes that it must rely on itself. As it realizes this, it starts to self-organize to take on the characteristics and behaviour of a real Team. - Scrum Guide, Scrum.org This paragraph goes to the why of having the whole team at the meeting; The goal of Scrum it to produce a unit of potentially shippable software at the end of every Sprint. In order to achieve this we need high performing teams and this is what Scrum as a framework has been optimised to produce. I think that our Product Owner is understandably upset over loosing two weeks work and is losing sight the end goal of Scrum in the failures of the moment. As the man spending the money, I completely understand his perspective and I think that we should not have started Scrum on an internal project, but selected a customer  that is open to the ideas and complications of Scrum. So, what should we have NOT done on our first Scrum project: Should not have had 3 interns as the only on site resource – This lead to bad practices as the experienced guys were not there helping and correcting as they usually would. Should not have had the only experienced guys offsite – With both the experienced technical guys in completely different time zones it was difficult to get time for questions. Helping the guys on site was just plain impossible. Should not have used a part time ScrumMaster – Although the ScrumMaster attended all of the Ceremonies, because they are only in 2 full days of the week it makes it difficult for the team to raise impediments as they go. Should not have used a proxy product owner. – This was probably the worst decision that was made. Mainly because the proxy product owner did not have the same vision as the product owner. While Scrum does not explicitly reject the idea of a Proxy Product Owner, I do not think it works very well in practice. The “single wringable neck” needs to contain both the Money and the Vision as well as attending the required meetings. I will be brining all of these things up at the Sprint Retrospective and we will learn from our mistakes and move on.

• Guidance: How to layout you files for an Ideal Solution

  - by Martin Hinshelwood

  Creating a solution and having it maintainable over time is an art and not a science. I like being pedantic and having a place for everything, no matter how small. For setting up the Areas to run Multiple projects under one solution see my post on  When should I use Areas in TFS instead of Team Projects and for an explanation of branching see Guidance: A Branching strategy for Scrum Teams. Update 17th May 2010 – We are currently trialling running a single Sprint branch to improve our history. Whenever I setup a new Team Project I implement the basic version control structure. I put “readme.txt” files in the folder structure explaining the different levels, and a solution file called “[Client].[Product].sln” located at “$/[Client]/[Product]/DEV/Main” within version control. Developers should add any projects you need to create to that solution in the format “[Client].[Product].[ProductArea].[Assembly]” and they will automatically be picked up and built automatically when you setup Automated Builds using Team Foundation Build. All test projects need to be done using MSTest to get proper IDE and Team Foundation Build integration out-of-the-box and be named for the assembly that it is testing with a naming convention of “[Client].[Product].[ProductArea].[Assembly].Tests” Here is a description of the folder layout; this content should be replicated in readme files under version control in the relevant locations so that even developers new to the project can see how to do it. Figure: The Team Project level - at this level there should be a folder for each the products that you are building if you are using Areas correctly in TFS 2010. You should try very hard to avoided spaces as these things always end up in a URL eventually e.g. "Code Auditor" should be "CodeAuditor". Figure: Product Level - At this level there should be only 3 folders (DEV, RELESE and SAFE) all of which should be in capitals. These folders represent the three stages of your application production line. Each of them may contain multiple branches but this format leaves all of your branches at the same level. Figure: The DEV folder is where all of the Development branches reside. The DEV folder will contain the "Main" branch and all feature branches is they are being used. The DEV designation specifies that all code in every branch under this folder has not been released or made ready for release. And feature branches MUST merge (Forward Integrate) from Main and stabilise prior to merging (Reverse Integration) back down into Main and being decommissioned. Figure: In the Feature branching scenario only merges are allowed onto Main, no development can be done there. Once we have a mature product it is important that new features being developed in parallel are kept separate. This would most likely be used if we had more than one Scrum team working on a single product. Figure: when we are ready to do a release of our software we will create a release branch that is then stabilised prior to deployment. This protects the serviceability of of our released code allowing developers to fix bugs and re-release an existing version. Figure: All bugs found on a release are fixed on the release.  All bugs found in a release are fixed on the release and a new deployment is created. After the deployment is created the bug fixes are then merged (Reverse Integration) into the Main branch. We do this so that we separate out our development from our production ready code.  Figure: SAFE or RTM is a read only record of what you actually released. Labels are not immutable so are useless in this circumstance.  When we have completed stabilisation of the release branch and we are ready to deploy to production we create a read-only copy of the code for reference. In some cases this could be a regulatory concern, but in most cases it protects the company building the product from legal entanglements based on what you did or did not release. Figure: This allows us to reference any particular version of our application that was ever shipped.   In addition I am an advocate of having a single solution with all the Project folders directly under the “Trunk”/”Main” folder and using the full name for the project folders.. Figure: The ideal solution If you must have multiple solutions, because you need to use more than one version of Visual Studio, name the solutions “[Client].[Product][VSVersion].sln” and have it reside in the same folder as the other solution. This makes it easier for Automated build and improves the discoverability of your code and its dependencies.

• Choosing the right TV tuner - USB or PCI TV tuners, hardware/software, DVB? Hybrid/combo/analog?

  - by Nucleon

  Greetings, I'll start with some background information so you know what I'm trying to accomplish and then get to my question. I work at a Television station in the US and we are working on setting up an online DVR/Podcast system for all of our newscasts. So basically we would be recording every newscast in HD, encoding it to flv/h.264 for viewing in a browser on flash compatible and iphone/ipad devices, eventually migrating to WebM when it's browser compliant. This task is theoretically pretty simple as it all it involves is a TV tuner device and a program like VLC, MythTV or whatever to schedule and dump it to a file, encode it with VLC/FFMPEG and push it to the streaming server. Now to the hardware, in order to accomplish that task, should I use an internal PCI tuner or a USB 2.0 tuner? Is there a difference? The bus speeds of both are not too far apart, and is the bus speed really relevant in this case? Does it matter if the device has a hardware encoder or a software encoder? On many sites the USB was recommended for ease of set up and use, but would it overly task a processor, or is that not a concern as long as it's a decent PC (at least duo core, 6gb ram). What's the difference between the stick USB and the Box USBs? To my understanding analog is basically gone in the US, so we would want a hybrid or combo tuner correct? How do those differ from DVB? Are there any other features or concepts which I am missing which may influence the recommended product. It would be ideal if the device which could work in both Linux and a Windows environment, to my knowledge most Hauppauge are? Example 1: PCI Hauppage http://www.newegg.com/Product/Product.aspx?Item=N82E16815116033 Example 2: USB 2.0 Box http://www.newegg.com/Product/Product.aspx?Item=N82E16815116029 Example 3: USB 2.0 Stick http://www.newegg.com/Product/Product.aspx?Item=N82E16815116031 Any guidance from the Superusers would be much appreciated!

• Debugging apache seg fault with gdb

  - by Joyce Babu

  Apache on a production server of mine is seg faulting intermittently. I have enabled core dump option in apache configuration and have several dumped core files. Unfortunately, since it is a production server, apache or the loaded modules are not compiled with debug symbols. From what I understand, gdb cannot do much without debug symbols. Can I at least find out which module is causing the seg fault, without debug symbols? If so, how? Following is the output from a gdb backtrace (gdb) bt full #0 0xb7f1f832 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 No symbol table info available. #1 0xb7be82bc in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 No symbol table info available. #2 0xb771652a in ??

Does this mean that /lib/ld-linux.so.2 is causing the seg fault?

• Tracking a subdomain serately within the main domain account [closed]

  - by Vinay

  I have a website, for example: xyz.com and info.xyz.com. I created a profile for xyz and tracking is good. I added a new profile for info.xyz.com in xyz.com. Analytics tracking for info.xyz.com is showing traffic from both xyz.com and info.xyz.com. How do I change to show only info.xyz traffic in the info.xyz.com profile. I used the following code: Analytics code for xyz.com domain: <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-xxxxxx-x']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> Analytics code for info.xyz.com <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-xxxxxx-x']); _gaq.push(['_setDomainName', 'xyz.com']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

• how to rewrite '%25' in url

  - by nn4l

  My website software replaces space characters with '+' characters in the URL, A proper link would look like 'http://www.schirmacher.de/display/INFO/How+to+reattach+a+disk+to+XenServer' for example. Some websites link to that article but somehow their embedded editor can't handle the encoding, so what I see in the httpd log files is actually GET /display/INFO/How%2525252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer which of course leads to a 404 error. It seems that the '+' character is encoded as '%2b' and then the '%' character is encoded as '%25' - several times. Since there are many such references to different pages from different websites, I would like to rewrite the url so that the visitors get the correct page. Here's my attempt which does not work: RewriteRule ^(.*)%25(.*)$ $1%$2 [R=301] What it is supposed to do is: take everything before the %25 string and everything after it, concat those strings with a '%' in between, then redirect. With the example input URL the rule should rewrite to /display/INFO/How%25252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer followed by a redirect, then it should rewrite to /display/INFO/How%252bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and again to /display/INFO/How%2bto%2525252breattach%2525252ba%2525252bdisk%2525252bto%2525252bXenServer and so on. Finally, after a lot of redirects I should have left /display/INFO/How%2bto%2breattach%2ba%2bdisk%2bto%2bXenServer which is a valid url equivalent to /display/INFO/How+to+reattach+a+disk+to+XenServer. My problem is that the expression does not match at all, so it does not even replace a single occurrence of %25. I understand that there is a limit in the number of redirects and I should really use the [N] flag however I don't even get the first step right.

• Use cell formatting (e.g. "Good", "Bad", "Neutral") in formulas?

  - by ngm

  I am compiling a comparison of different pieces of software in an Excel spreadsheet. It is a big long list of features (the rows), with each column being one of the applications I'm evaluating. I've used styles to visually show how well each product meets each feature, as well as the importance of that feature, and now I'm wondering if there's a way I can use those annotations in a formula. The table is like: . | Product A | Product B | Product C Feature A | blah blah blah Feature B | blah blah blah Feature C | blah blah blah .... | .... | etc | Where I've put 'blah' in the table above, in my actual spreadsheet is (potentially lengthy) descriptive text explaining something about this feature in the given product. I've then used the styles "Good", "Neutral" and "Bad" to visually annotate the description, to show how well each product meets that feature. For each feature I've also used the styles Accent4, 60% Accent4, 40% Accent4, etc, to annotate the importance of each feature. Now I'm wondering if somehow I can use those styles (the annotations) to tot up a total score for each product. e.g., Score for feature A = valueof(60% Accent4) * valueof(Good) Is it possible at all?
