• Culture Shmulture?

  - by steve.diamond

  I've been thinking about "Customer Experience Management" lately. Here at Oracle, we arguably have the most complete suite of applications for managing the customer experience across and in the context of multiple channels -- from marketing to loyalty to contact center to self-service to analytics offerings, and more. And stay tuned, because in coming months let's just say we'll have even more to talk about on this front. But that said............ Last weekend my wife and I stayed at one of the premiere hotel chains on the planet. I won't name them, but we all know the short list. It could have been the St. Regis or the Ritz Carlton or Four Seasons or Hyatt Park or....This stay, at this particular hotel, was simply outstanding. Within a chain known for providing "above and beyond" levels of service, this particular hotel, under this particular manager, exceeded expectations on so many fronts. For example, at the Spa we mentioned to the two attendants that my wife is seven months pregnant and that we had previously had a lot of trouble conceiving. We then went to our room. Ten minutes later we heard a knock at the door and received a plate of chocolate covered strawberries with a heartfelt note and an inspiring quote, signed by the two spa attendees. The following day we arranged to have a bellhop drive us to the beach. Although they had a pre-arranged beach shuttle service with time limits, etc., he greeted us by saying, "I'm yours for the day until 4 p.m. Whatever you want to do is fine by me, as long as it's legal!" The morning that we left we arranged to have a taxi drive us to the airport--a nearly 40 mile drive. What showed up was a private coach complete with navy blue suited driver dude. And we were charged the taxi fare price. And there were many other awesome exchanges I won't mention here, although I did email the GM of this hotel two nights ago and expressed our effusive praise and gratitude. I'd submit that this hotel chain would have a definitive advantage using even more Oracle software to manage and optimize its customer interactions (yes, they are a customer). But WITHOUT the culture--that management team--and that instillation of aligned values across all employees of exemplifying 'the golden rule,' I wonder how much technology really matters in providing a distinctively positive and memorable customer experience. Lest you think I'm alone in these pontifications, have you read Paul Greenberg's blog lately? Have you seen one of his most recent posts? Now this SPECIFIC post is NOT about customer service per se. But it is about people. So yes, please think long and hard about the technology you seek to deploy. But never forget who will be interacting with your systems, and your customers.

• Working with EO composition associations via ADF BC SDO web services

  - by Chris Muir

  ADF Business Components support the ability to publish the underlying Application Modules (AMs) and View Objects (VOs) as web services through Service Data Objects (SDOs).  This blog post looks at a minor challenge to overcome when using SDOs and Entity Objects (EOs) that use a composition association. Using the default ADF BC EO association behaviour ADF BC components allow you to work with VOs that are based on EOs that are a part of a parent-child composition association.  A composition association enforces that you cannot create records for the child outside the context of the parent.  As example when creating invoice-lines you want to enforce the individual lines have a relating parent invoice record, it just simply doesn't make sense to save invoice-lines without their parent invoice record. In the following screenshot using the ADF BC Tester it demonstrates the correct way to create a child Employees record as part of a composition association with Departments: And the following screenshot shows you the wrong way to create an Employee record: Note the error which is enforced by the composition association: (oracle.jbo.InvalidOwnerException) JBO-25030: Detail entity Employees with row key null cannot find or invalidate its owning entity.  Working with composition associations via the SDO web services  Shay Shmeltzer recently recorded a good video which demonstrates how to expose your ADF Business Components through the SDO interface. On exposing the VOs you get a choice of operation to publish including create, update, delete and more: For example through the SDO test interface we can see that the create operation will request the attributes for the VO exposed, in this case EmployeesView1: In this specific case though, just like the ADF BC Tester, an attempt to create this record will fail with JBO-25030, the composition association is still enforced: The correct way to to do this is through the create operation on the DepartmentsView1 which also lets you create employees record in context of the parent, thus satisfying the composition association rule: Yet at issue here is the create operation will always create both the parent Departments and Employees records.  What do we do if we've already previously created the parent Departments records, and we just want to create additional Employees records for that Department?  The create method of the EmployeeView1 as we saw previously doesn't allow us to do that, the JBO-3050 error will be raised. The solution is the "merge" operation on the parent Departments record: In this case for the Departments record you just need to supply the DepartmentId of the Department you want the Employees record to be associated with, as well as the new Employees record.  When invoked only the Employees record is created, and the supply of the DepartmentId of the Departments record satisfies the composition association without actually creating or updating the associated Department record that already exists in the database. Be warned however if you supply any more attributes for the Department record, it will result in a merge (update) of the associated Departments record too.

• Hey You! Stop Using the Apply Button and Just Click OK! [Geek Rants]

  - by The Geek

  As a computer geek, I often find myself helping people, and watching them change settings on their PC… and they almost always click the Apply button, and then the OK button. Why? Whenever you encounter a dialog box in Windows, there are the standard OK, Cancel, Apply buttons—but you don’t actually have to click the Apply button first. The OK button does the same thing, saves the settings, and then closes the dialog box… saving you an extra click. Don’t believe me? Try it out for yourself. Only the worst possible application won’t behave that way, and you probably don’t want to use that type of application to begin with. The only exception to this rule is a multiple tab dialog box, on a badly written application. Sometimes… your settings on one tab won’t stick unless you click Apply. Note that in this particular case, you can make changes in any one of the tabs, and they will carry through without having to click Apply, because this dialog window is well written. We’re just using the screenshot as an example of a multiple tab setting interface. So now that you know better, you can tell us… do you always use the Apply button first? Have you ever found an instance where it behaves differently? Similar Articles Productive Geek Tips Got Awesome Skills?

• Is commented out code really always bad?

  - by nikie

  Practically every text on code quality I've read agrees that commented out code is a bad thing. The usual example is that someone changed a line of code and left the old line there as a comment, apparently to confuse people who read the code later on. Of course, that's a bad thing. But I often find myself leaving commented out code in another situation: I write a computational-geometry or image processing algorithm. To understand this kind of code, and to find potential bugs in it, it's often very helpful to display intermediate results (e.g. draw a set of points to the screen or save a bitmap file). Looking at these values in the debugger usually means looking at a wall of numbers (coordinates, raw pixel values). Not very helpful. Writing a debugger visualizer every time would be overkill. I don't want to leave the visualization code in the final product (it hurts performance, and usually just confuses the end user), but I don't want to loose it, either. In C++, I can use #ifdef to conditionally compile that code, but I don't see much differnce between this: /* // Debug Visualization: draw set of found interest points for (int i=0; i<count; i++) DrawBox(pts[i].X, pts[i].Y, 5,5); */ and this: #ifdef DEBUG_VISUALIZATION_DRAW_INTEREST_POINTS for (int i=0; i<count; i++) DrawBox(pts[i].X, pts[i].Y, 5,5); #endif So, most of the time, I just leave the visualization code commented out, with a comment saying what is being visualized. When I read the code a year later, I'm usually happy I can just uncomment the visualization code and literally "see what's going on". Should I feel bad about that? Why? Is there a superior solution? Update: S. Lott asks in a comment Are you somehow "over-generalizing" all commented code to include debugging as well as senseless, obsolete code? Why are you making that overly-generalized conclusion? I recently read Robert Glass' "Clean Code", which says: Few practices are as odious as commenting-out code. Don't do this!. I've looked at the paragraph in the book again (p. 68), there's no qualification, no distinction made between different reasons for commenting out code. So I wondered if this rule is over-generalizing (or if I misunderstood the book) or if what I do is bad practice, for some reason I didn't know.

• How to design a scalable notification system?

  - by Trent

  I need to write a notification system manager. Here is my requirements: I need to be able to send a Notification on different platforms, which may be totally different (for exemple, I need to be able to send either an SMS or an E-mail). Sometimes the notification may be the same for all recipients for a given platform, but sometimes it may be a notification per recipients (or several) per platform. Each notification can contain platform specific payload (for exemple an MMS can contains a sound or an image). The system need to be scalable, I need to be able to send a very large amount of notification without crashing either the application or the server. It is a two step process, first a customer may type a message and choose a platform to send to, and the notification(s) should be created to be processed either real-time either later. Then the system needs to send the notification to the platform provider. For now, I end up with some though but I don't know how scalable it will be or if it is a good design. I've though of the following objects (in a pseudo language): a generic Notification object: class Notification { String $message; Payload $payload; Collection<Recipient> $recipients; } The problem with the following objects is what if I've 1.000.000 recipients ? Even if the Recipient object is very small, it'll take too much memory. I could also create one Notification per recipient, but some platform providers requires me to send it in batch, meaning I need to define one Notification with several Recipients. Each created notification could be stored in a persistent storage like a DB or Redis. Would it be a good it to aggregate this later to make sure it is scalable? On the second step, I need to process this notification. But how could I distinguish the notification to the right platform provider? Should I use an object like MMSNotification extending an abstract Notification? or something like Notification.setType('MMS')? To allow to process a lot of notification at the same time, I think a messaging queue system like RabbitMQ may be the right tool. Is it? It would allow me to queue a lot of notification and have several worker to pop notification and process them. But what if I need to batch the recipients as seen above? Then I imagine a NotificationProcessor object for which I could I add NotificationHandler each NotificationHandler would be in charge to connect the platform provider and perform notification. I can also use an EventManager to allow pluggable behavior. Any feedbacks or ideas? Thanks for giving your time. Note: I'm used to work in PHP and it is likely the language of my choice.

• How (recipe) to build only one kernel module?

  - by Pro Backup

  I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash).

• The importance of Unit Testing in BI

  - by Davide Mauri

  One of the main steps in the process we internally use to develop a BI solution is the implementation of Unit Test of you BI Data. As you may already know, I’ve create a simple (for now) tool that leverages NUnit to allow us to quickly create Unit Testing without having to resort to use Visual Studio Database Professional: http://queryunit.codeplex.com/ Once you have a tool like this one, you can start also to make sure that your BI solution (DWH and CUBE) is not only structurally sound (I mean, the cube or the report gets processed correctly), but you can also check that the logical integrity of your business rules is enforced. For example let’s say that the customer tell you that they will never create an invoice for a specific product-line in 2010 since that product-line is dismissed and will never be sold again. Ok we know that this in theory is true, but a lot of this business rule effectiveness depends on the fact the people does not do a mistake while inserting new orders/invoices and the ERP used implements a check for this business logic. Unfortunately these last two hypotesis are not always true, so you may find yourself really having some invoices for a product line that doesn’t exists anymore. Maybe this kind of situation in future will be solved using Master Data Management but, meanwhile, how you can give and idea of the data quality to your customers? How can you check that logical integrity of the analytical data you produce is exactly what you expect? Well, Unit Testing of a DWH or a CUBE can be a solution. Once you have defined your test suite, by writing SQL and MDX queries that checks that your data is what you expect to be, if you use NUnit (and QueryUnit does), you can then use a tool like NUnit2Report to create a nice HTML report that can be shipped via email to give information of data quality: In addition to that, since NUnit produces an XML file as a result, you can also import it into a SQL Server Database and then monitor the quality of data over time. I’ll be speaking about this approach (and more in general about how to “engineer” a BI solution) at the next European SQL PASS Adaptive BI Best Practices http://www.sqlpass.org/summit/eu2010/Agenda/ProgramSessions/AdaptiveBIBestPratices.aspx I’ll enjoy discussing with you all about this, so see you there! And remember: “if ain't tested it's broken!” (Sorry I don’t remember how said that in first place :-)) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Best practices for logging and tracing in .NET

  - by Levidad

  I've been reading a lot about tracing and logging, trying to find some golden rule for best practices in the matter, but there isn't any. People say that good programmers produce good tracing, but put it that way and it has to come from experience. I've also read similar questions in here and through the internet and they are not really the same thing I am asking or do not have a satisfying answer, maybe because the questions lack some detail. So, folks say that tracing should sort of replicate the experience of debugging the application in cases where you can't attach a debugger. It should provide enough context so that you can see which path is taken at each control point in the application. Going deeper, you can even distinguish between tracing and event logging, in that "event logging is different from tracing in that it captures major states rather than detailed flow of control". Now, say I want to do my tracing and logging using only the standard .NET classes, those in the System.Diagnostics namespace. I figured that the TraceSource class is better for the job than the static Trace class, because I want to differentiate among the trace levels and using the TraceSource class I can pass in a parameter informing the event type, while using the Trace class I must use Trace.WriteLineIf and then verify things like SourceSwitch.TraceInformation and SourceSwitch.TraceErrors, and it doesn't even have properties like TraceVerbose or TraceStart. With all that in mind, would you consider a good practice to do as follows: Trace a "Start" event when begining a method, which should represent a single logical operation or a pipeline, along with a string representation of the parameter values passed in to the method. Trace an "Information" event when inserting an item into the database. Trace an "Information" event when taking one path or another in an important if/else statement. Trace a "Critical" or "Error" in a catch block depending on weather this is a recoverable error. Trace a "Stop" event when finishing the execution of the method. And also, please clarify when best to trace Verbose and Warning event types. If you have examples of code with nice trace/logging and are willing to share, that would be excelent. Note: I've found some good information here, but still not what I am looking for: http://msdn.microsoft.com/en-us/magazine/ff714589.aspx Thanks in advance!

• Using ext4 in VMware machine

  First of all, using a journaling filesystems like NTFS, ext4, XFS, or JFS (not to name all of them) is a very good idea and nowadays unthinkable not to do. Linux offers a good variety of different option as journaling filesystem for your system. Since years I am using SGI's XFS and I am pretty confident with stability, performance and liability of the system. In earlier years I had to struggle with incompatibilities between XFS and the boot loader. Using an ext2 formatted /boot solved this issue. But, wow, that is ages ago! Lately, I had to setup a fresh Lucid Lynx (Ubuntu 10.04 LTS) system for a change of our internal groupware / messaging system. Therefore, I fired up a new virtual machine with almost standard configuration in VMware Server and run through our network-based PXE boot and installation procedure. At a certain step in this process, Ubuntu asks you about the partitioning of your hard drive(s). Honestly, I have to say that only out of curiousity I sticked to the "default" suggestion and gave my faith and trust into the Ubuntu installation routine... Resulting to have an ext4 based root mount point ( / ). The rest of the installation went on without further concerns or worries. Note:I really can't remember why I chose to go away from my favourite... Well, it should turn out to be the wrong decision after all. Ok, let's continue the story about ext4 in a VMware based virtual machine. After some hours installing additional packages and configuring the new system using LDAP for general authentication and login, I had an "out-of-the-box" usable enterprise messaging system based on Zarafa 6.40 Community Edition inclusive proper SSL-based Webaccess interface and Z-Push extension for ActiveSync with my Nokia mobile. Straightforward and pretty nice for the time spent on the setup. Having priority on other tasks I let the system just running and didn't pay any further attention at all. Until I run into an upgrade of "Mail for Exchange" on Symbian OS. My mobile did not bother me at all with the upgrade and everything went smooth, but trying to re-establish the ActiveSync connection to the Zarafa messaging system resulted in a frustating situation. So, I shifted my focus back to the Linux system and I was amazed to figure out that the root had been remounted readonly due to hard drive failures or at least ext4 reported errors. Firing up Google only confirmed my concerns and it seems that using ext4 for VMware based virtual machines does not look like a stable and reliable candidate to me. You might consider reading those external resources: ext4 fs corruption under VMWare Server 2.01Bug #389555 - ext4 filesystem corruption Well, I learned my lesson and ext{2|3|4} based filesystems are not going to be used on any of my Linux systems or customer installations in the future. Addendum: I did not try this setup in other virtualization environments like VirtualBox, qemu, kvm, Xen, etc.

• How do I fix postfix TLS?

  - by Savanni D'Gerinel

  STARTTLS was working with my system earlier today. Without me altering the system in any way, it spontaneously broke. I've now been trying to fix it for a couple of hours, to no success. When I connect to the server, this is what I get: savanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.sasavanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.savannidgerinel.com.

Okay, obviously STARTTLS isn't present in this list. So I've been digging through my configuration files and working through the tutorials again, and that has done me no good at all. Here's my tls-related configuration: smtp_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtp_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtp_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtpd_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtpd_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtpd_tls_loglevel = 3 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache tls_random_source = dev:/dev/urandom All of the certificate files are present, the server private key is present, the server CA is present, and the smtpd_scache.db and smtp_scache.db files are both present.

• Rights and use of developed software

  - by Nils Munch

  I have been working on a piece of software for a company, that they wish to resell. There was an mail-based agreement upon a flat hourly rate for my work, and eager me chose to accept a rather low fee. Due to the stress and tempo of the task, a direct contract was never formed or signed. The software was developed locally on my machine, and I was pretty much alone with it, except by excellent help from StackOverflow when I got stuck. Now, the software is nearing completion, I suddenly hear that they have hired a new developer to make the same piece of software as me, and that I was expected to resign within long. Confused I ask around, and realize that the CEO of the company had informed the rest of the company that I was terminally ill and had cancer, and was expected to leave the company soon. Since I'm perfectly healthy, this confused me even more, until I realized what was going on. When I confronted my boss with this, I was no longer seen as a member of the company, and I left the same day, never to return. Later, I raised the question about my missing pay, since I had been working for quite a bit, and not received any payment for my software. I saw that they had already sold a fair copy of my software, and since it's not exactly sold cheap, the company should have plenty of gold to pay me. The company refused, and said that they owned the software, and everything it contained. That was a lot of drama, but my question is this: Who has the rights to the software ? The source code had my personal watermarks and copyrights inprinted, but they have since simply deleted it. The company claim that they have all the rights, because they have a website made about the product, where they write that they have "All rights reserved" in the bottom. My instinct tells me that if a company buys a service like this, and then refuses to pay their developer, then they should not be allowed to keep, and much less resell the product. I have not signed any agreements about giving the company the use of this product, I have made it in my own time and without help from the rest of the company. This all takes place in Denmark, Europe, but I would guess that the rules about this is somewhat universal. Im not the strongest person to legal-talk, so I might be wrong.

• Databases and Beer

  - by Johnm

  It is a bit of a no-brainer: Include the word "beer" in a subject line of an e-mail or blog post title and you can be certain that it will be read. While there are times this practice might be a ploy to increase readership, it is not the case for this blog post. There is inspiration that can be drawn from other industries to which we, as database professionals, can apply in our industry. In this post I will highlight one of my favorite participants of the brewing industry. The Boston Beer Company started in the 1970s in Boston, Massachusetts. Others may be more familiar with this company through their Samuel Adams Boston Lager and other various seasonal beers. I am continually inspired by their commitment to mastery of the brewing process to which they evangelize frequently in their commercials. They also are continually in pursuit of pushing the boundaries of beer as we know it while working within traditional constraints. A recent example of this is their collaboration with Weihenstephan Brewery of Munich, Germany to produce the soon to be released Infinium beer. This beer, while brewed as an ale, is touted as something closer to something like Champaign - all while complying with the Reinheitsgebot. The Reinheitsgebot is also known as the "German Beer Purity Law" which was originated in 1516. This law states that beer is to consist of water, barley, hops and yeast. That's it. Quite a limiting constraint indeed. and yet, The Boston Beer Company pushed forward. Much like the process of brewing, the discipline of database design and architecture is one that is continually in process and driven by the pursuit of mastery. While we do not have purity laws to constrain us, we have many other types: best practices, company policies, government regulations, security and budgets. Through our fellow comrades, we discuss the challenges and constraints in which we operate. We boil down the principles and theories that define our profession. We reassemble these into something that is complementary to the business needs that we must fulfill. As a result, it is not uncommon to see something amazingly innovative in a small business who is pushing the boundaries of their database well beyond its intended state. It is equally common to see innovation in the use of features available in the more advanced features of databases that are found in large businesses. The tag line for The Boston Beer Company is: "Take Pride In Your Beer.", I would like to offer an alternative and say "Take Pride In Your Database." So, As you pour your next Boston Lager into a frosted glass, consider those who spend their lives mastering the craft of brewing and strive to interject their spirit into everything that you do as a database professional. Cheers!

• What do you think of the EntLib 5.0 configuration tool?

  Hello again! Its been a while, I know. Ive been busy over the last few months with several projects, some of them software related, and one of them human my son Jesse was born on 26 February 2010. Fun times! Meanwhile, back in Redmond, the p&p team has been busy working on Enterprise Library 5.0 see Grigoris announcement for details on the beta. Theres a ton of new stuff in this release, but theres one big new feature that hasnt received a lot of attention that Im keen to hear your perspectives on. The change is the biggest overhaul to the configuration tool since Enterprise Library was launched. If you havent yet grabbed the EntLib 5.0 beta, heres a before and after shot of the config tool: Enterprise Library 4.1 config tool Enterprise Library 5.0 (beta 1) config tool The tool has been rebuilt from the ground up in response to some feedback and usability studies from the previous version of the tool. But is this a step in the right direction? Id love to hear what you think. If youve downloaded EntLib 5.0 and tried out the tool, please share your thoughts on: First impressions. Is the tool easy to understand? Easy to find what youre looking for? Easy to read existing configuration? Pretty? Ease of use for real life tasks. Rather than make up your own tasks, here are a few sample scenarios you might want to try: Configure the data access block with a SQL Server connection called Audit that points to a database called Audit on a server called DB Configure the logging block so that any log entries in the Audit category are written to both the Event Log and the Audit database (see above) Configure the validation block with a ruleset called Email Address that uses an appropriate regular expression for e-mail addresses Configure the policy injection block such that any calls to classes in the MyCompany.Security namespace are logged before and after the call using the Audit category (see above) Comparison with the old config tool. What do you like better in the new tool? What did you like better in the old tool? How do you rate your level of expertise using the old tool? Keep in mind that I no longer work in the p&p team, so I cant say how any of this feedback will be used (although Im sure the team is listening!). However since Ive invested so much time in Enterprise Library, both in leading the team and using the product on real projects Im very interested to hear what you all think of the tools new direction.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Azure Service Bus - Authorization failure

  - by Michael Stephenson

  I fell into this trap earlier in the week with a mistake I made when configuring a service to send and listen on the azure service bus and I thought it would be worth a little note for future reference as I didnt find anything online about it.  After configuring everything when I ran my code sample I was getting the below error. WebHost failed to process a request.Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/28316044Exception: System.ServiceModel.ServiceActivationException: The service '/-------/BrokeredMessageService.svc' cannot be activated due to an exception during compilation.  The exception message is: Generic: There was an authorization failure. Make sure you have specified the correct SharedSecret, SimpleWebToken or Saml transport client credentials.. ---> Microsoft.ServiceBus.AuthorizationFailedException: Generic: There was an authorization failure.
