  • Oracle Social Network Developer Challenge: Fishbowl Solutions

    - by Kellsey Ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network. Although this is the final, official entry we had, tomorrow, I’ll show you the work of someone who finished code, but wasn’t able to make the judging event. Stay tuned.

  • Have Your Cake and Eat it Too: Industry Best Practices + Flexibility

    - by Oracle Accelerate for Midsize Companies
    By Richard Garraputa, VP of Sales & Marketing, brij Richard joined brij in 1996 after graduating from the University of North Carolina at Greensboro with degrees in Information Systems and Accounting. He directs brij’s overall strategies of both the business development and marketing departments. Companies looking for new ERP systems spend so much time comparing features and functions of software products but too often short change the value of their own processes.  Company managers I meet often claim that they are implementing a new ERP system so they can perform better and faster.  When asked how, the answer is often “by implementing best practices”.  But the term ‘best practices’ is frequently used to mean ‘doing things the way everyone else does them’ rather than a starting point or benchmark to build upon by adding your own value. Of course, implementing standardized processes across an enterprise is an important step in improving operational efficiencies.  But not all companies are alike.  Do you ever tell your customers “We are just like our competition and have no competitive differentiation”?  Probably not.  So why should the implementation of your business processes be just like your competitor’s?  Even within the same industry, companies differentiate themselves by leveraging their unique expertise and approach to business.  These unique aspects—the competitive differentiators that companies use to thrive in a crowded marketplace—can and should be supported by the implementation of business systems like ERP. Modern ERP systems like Oracle’s JD Edwards EnterpriseOne have a broad and deep functional footprint designed to integrate a company’s core operations.  But how can a company take advantage of this footprint without blowing up their implementation budget?  Some ERP vendors claim to solve this challenge by stating that their systems come pre-configured with ‘best practices’.  Too often what they are really saying is that you will have to abandon your key operational differentiators to fit a vendor’s template for your business—or extend your implementation and postpone the realization of any benefits. Thankfully for midsize companies, there is an alternative to the undesirable options of extended implementation projects or abandoning their competitive differentiators.  Oracle Accelerate Solutions speed the time it takes to implement JD Edwards EnterpriseOne solution based on your unique business characteristics, getting your new ERP system up and running faster without forcing your business to fit a cookie-cutter solution. We’ve been a JD Edwards implementation partner since 1986 and we now leverage Oracle Business Accelerators—cloud based rapid implementation tools built and maintained by Oracle. Oracle Business Accelerators deliver the benefits of embedded industry best practices without forcing every customer in to one set of processes like many template or “clone and go” approaches do. You retain the ability to reconfigure your applications—without customization—as your business changes. Wielded by Oracle partners with industry-specific domain expertise, Oracle Accelerate Solution implementations powered by Oracle Business Accelerators help automate the application configuration to fit your business better, faster. For example, on a recent project at a manufacturing company, the project manager told me that Oracle Business Accelerators helped get them to Conference Room Pilot 20% faster than with a traditional approach. Time savings equal cost savings. And if ‘better and faster’ is your goal for your business performance, shouldn’t it be the goal for your ERP implementation as well? Established in 1986, brij has been dedicated solely to helping its customers implement Oracle’s JD Edwards solutions and to maximize the value of those customers’ IT investments. They are a Gold level member in Oracle PartnerNetwork and an Oracle Accelerate Solution provider.

  • How to Build Services from Legacy Applications

    - by Chris Falter
    The SOA consultants invaded the executive suite at your company or agency, preached the true religion, and converted the unbelievers. Now by divine imperative you must convert your legacy applications into a suite of reusable services.  But as usual, you lack the time and resources that you need in order to develop the services properly.  So you googled or bing’ed, found this blog post, and began crying in gratitude.  Yes, as the title implies, I am going to reveal my easy, 3-step, works-every-time process for converting silos of legacy applications into the inventory of services your CIO has been dreaming about.  So just close your eyes and count to 3 … now open them … and here it is…. Not. While wishful thinking is too often the coin of the IT realm, even the most naive practitioner knows that converting legacy applications into reusable services requires more than a magic wand.  The reason is simple: if your starting point is your legacy applications, then you will simply be bolting a web service technology layer on top of your legacy API.  And that legacy API is built in the image of the silo applications.  Enter the wide gate of the legacy API, follow the broad path of generating service interfaces from existing code, and you will arrive at the siloed enterprise destruction that you thought you were escaping. The Straight and Narrow Path This past week I had the opportunity to learn how the FBI Criminal Justice Information Systems department has been transitioning from silo applications to a service inventory.  Lafe Hutcheson, IT Specialist in the architecture group and fellow attendee at an SOA Architect Certification Workshop, was my guide.  Lafe has survived the chaos of an SOA initiative, so it is not surprising that he was able to return from a US Army deployment to Kabul, Afghanistan with nary a scratch.  According to Lafe, building their service inventory is a three-phase process: Model a business process.  This requires intense collaboration between the IT and business wings of the organization, of course.  The FBI uses IBM Websphere tools to model the process with BPMN. Identify candidate services to facilitate the business process. Convert the BPMN to an executable BPEL orchestration, model and develop the services, and use a BPEL engine to run the process.  The FBI uses ActiveVOS for orchestration services. The 12 Step Program to End Your Legacy API Addiction Thomas Erl has documented a process for building a web service inventory that is quite similar to the FBI process. Erl’s process adds a technology architecture definition phase, which allows for the technology environment to influence the inventory blueprint.  For example, if you are using an enterprise service bus, you will probably not need to build your own utility services for logging or intermediate routing.  Erl also lists a service-oriented analysis phase that highlights the 12-step process of applying the principles of service orientation to modeling your services.  Erl depicts the modeling of a service inventory as an iterative process: model a business process, define the relevant technology architecture, define the service inventory blueprint, analyze the services, then model another business process, rinse and repeat.  (Astute readers will note that Erl’s diagram, restricted to analysis and modeling process, does not include the implementation phase that concludes the FBI service development methodology.) The service-oriented analysis phase is where you find the 12 steps that will free you from your legacy API addiction. In a nutshell, you identify the steps in the process that need services; identify the different types of services (agnostic entity services, service compositions, and utility services) that are required; apply service-orientation principles; and normalize the inventory into cohesive service models. Rather than discuss each of the 12 steps individually, I will close by simply referring my readers to Erl’s explanation.

  • SSIS Technique to Remove/Skip Trailer and/or Bad Data Row in a Flat File

    - by Compudicted
    I noticed that the question on how to skip or bypass a trailer record or a badly formatted/empty row in a SSIS package keeps coming back on the MSDN SSIS Forum. I tried to figure out the reason why and after an extensive search inside the forum and outside it on the entire Web (using several search engines) I indeed found that it seems even thought there is a number of posts and articles on the topic none of them are employing the simplest and the most efficient technique. When I say efficient I mean the shortest time to solution for the fellow developers. OK, enough talk. Let’s face the problem: Typically a flat file (e.g. a comma delimited/CSV) needs to be processed (loaded into a database in most cases really). Oftentimes, such an input file is produced by some sort of an out of control, 3-rd party solution and would come in with some garbage characters and/or even malformed/miss-formatted rows. One such example could be this imaginary file: As you can see several rows have no data and there is an occasional garbage character (1, in this example on row #7). Our task is to produce a clean file that will only capture the meaningful data rows. As an aside, our output/target may be a database table, but for the purpose of this exercise we will simply re-format the source. Let’s outline our course of action to start off: Will use SSIS 2005 to create a DFT; The DFT will use a Flat File Source to our input [bad] flat file; We will use a Conditional Split to process the bad input file; and finally Dump the resulting data to a new [clean] file. Well, only four steps, let’s see if it is too much of work. 1: Start the BIDS and add a DFT to the Control Flow designer (I named it Process Dirty File DFT): 2, and 3: I had added the data viewer to just see what I am getting, alas, surprisingly the data issues were not seen it:   What really is the key in the approach it is to properly set the Conditional Split Transformation. Visually it is: and specifically its SSIS Expression LEN([After CS Column 0]) > 1 The point is to employ the right Boolean expression (yes, the Conditional Split accepts only Boolean conditions). For the sake of this post I re-named the Output Name “No Empty Rows”, but by default it will be named Case 1 (remember to drag your first column into the expression area)! You can close your Conditional Split now. The next part will be crucial – consuming the output of our Conditional Split. Last step - #4: Add a Flat File Destination or any other one you need. Click on the Conditional Split and choose the green arrow to drop onto the target. When you do so make sure you choose the No Empty Rows output and NOT the Conditional Split Default Output. Make the necessary mappings. At this point your package must look like: As the last step will run our package to examine the produced output file. F5: and… it looks great!

  • MPI Cluster Debugger launch integration in VS2010

    Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging. Ensure the "Debugger to launch" combo box value is set to MPI Cluster Debugger.2. There are a whole bunch of properties here and typically you can ignore all of them except one: Run Environment. By default it is set to run 1 process on your local machine and if you change the number after that to, for example, 4 it will launch 4 processes of your app on your local machine.You want this to run on your cluster though, so go to the dropdown arrow at the end of the Run Environment cell and open it to expose the "Edit Hpc node" menu which opens the Node Selector dialog:In this dialog you can enter (or pick from a list) the cluster head node name and then the number of processes you want to execute on the cluster and then hit OK and… you are done.3. Press F5 and watch your breakpoint get hit (after giving it some time for copying, remote execution, attachment and symbol resolution to take place).GOING DEEPERIn the MPI Cluster Debugger project properties above, you can see many additional properties to the Run Environment. They are all optional, but you may want to understand them in order to fine tune your cluster debugging. Read all about each one of these on the MSDN page Configuration Properties for the MPI Cluster Debugger.In the Node Selector dialog above you can see more options than just the Head Node name and Number of Process to run. They should be self-explanatory but I also cover them in depth in my screencast showing you an example of why you would choose to schedule processes per core versus per node. You can also read about these options on MSDN as part of the page How to: Configure and Launch the MPI Cluster Debugger.To read through an example that touches on MPI project creation, project properties, node selector, and also usage of MPI with OpenMP plus MPI with PPL, read the MSDN page Walkthrough: Launching the MPI Cluster Debugger in Visual Studio 2010.Happy MPI debugging!

  • Be the surgeon

    - by Rob Farley
    It’s a phrase I use often, especially when teaching, and I wish I had realised the concept years earlier. (And of course, fits with this month’s T-SQL Tuesday topic, hosted by Argenis Fernandez) When I’m sick enough to go to the doctor, I see a GP. I used to typically see the same guy, but he’s moved on now. However, when he has been able to roughly identify the area of the problem, I get referred to a specialist, sometimes a surgeon. Being a surgeon requires a refined set of skills. It’s why they often don’t like to be called “Doctor”, and prefer the traditional “Mister” (the history is that the doctor used to make the diagnosis, and then hand the patient over to the person who didn’t have a doctorate, but rather was an expert cutter, typically from a background in butchering). But if you ask the surgeon about the pain you have in your leg sometimes, you’ll get told to ask your GP. It’s not that your surgeon isn’t interested – they just don’t know the answer. IT is the same now. That wasn’t something that I really understood when I got out of university. I knew there was a lot to know about IT – I’d just done an honours degree in it. But I also knew that I’d done well in just about all my subjects, and felt like I had a handle on everything. I got into developing, and still felt that having a good level of understanding about every aspect of IT was a good thing. This got me through for the first six or seven years of my career. But then I started to realise that I couldn’t compete. I’d moved into management, and was spending my days running projects, rather than writing code. The kids were getting older. I’d had a bad back injury (ask anyone with chronic pain how it affects  your ability to concentrate, retain information, etc). But most of all, IT was getting larger. I knew kids without lives who knew more than I did. And I felt like I could easily identify people who were better than me in whatever area I could think of. Except writing queries (this was before I discovered technical communities, and people like Paul White and Dave Ballantyne). And so I figured I’d specialise. I wish I’d done it years earlier. Now, I can tell you plenty of people who are better than me at any area you can pick. But there are also more people who might consider listing me in some of their lists too. If I’d stayed the GP, I’d be stuck in management, and finding that there were better managers than me too. If you’re reading this, SQL could well be your thing. But it might not be either. Your thing might not even be in IT. Find out, and then see if you can be a world-beater at it. But it gets even better, because you can find other people to complement the things that you’re not so good at. My company, LobsterPot Solutions, has six people in it at the moment. I’ve hand-picked those six people, along with the one who quit. The great thing about it is that I’ve been able to pick people who don’t necessarily specialise in the same way as me. I don’t write their T-SQL for them – generally they’re good enough at that themselves. But I’m on-hand if needed. Consider Roger Noble, for example. He’s doing stuff in HTML5 and jQuery that I could never dream of doing to create an amazing HTML5 version of PivotViewer. Or Ashley Sewell, a guy who does project management far better than I do. I could go on. My team is brilliant, and I love them to bits. We’re all surgeons, and when we work together, I like to think we’re pretty good! @rob_farley

  • Taking a screenshot from within a Silverlight #WP7 application

    - by Laurent Bugnion
    Often times, you want to take a screenshot of an application’s page. There can be multiple reasons. For instance, you can use this to provide an easy feedback method to beta testers. I find this super invaluable when working on integration of design in an app, and the user can take quick screenshots, attach them to an email and send them to me directly from the Windows Phone device. However, the same mechanism can also be used to provide screenshots are a feature of the app, for example if the user wants to save the current status of his application, etc. Caveats Note the following: The code requires an XNA library to save the picture to the media library. To have this, follow the steps: In your application (or class library), add a reference to Microsoft.Xna.Framework. In your code, add a “using” statement to Microsoft.Xna.Framework.Media. In the Properties folder, open WMAppManifest.xml and add the following capability: ID_CAP_MEDIALIB. The method call will fail with an exception if the device is connected to the Zune application on the PC. To avoid this, either disconnect the device when testing, or end the Zune application on the PC. While the method call will not fail on the emulator, there is no way to access the media library, so it is pretty much useless on this platform. This method only prints Silverlight elements to the output image. Other elements (such as a WebBrowser control’s content for instance) will output a black rectangle. The code public static void SaveToMediaLibrary( FrameworkElement element, string title) { try { var bmp = new WriteableBitmap(element, null); var ms = new MemoryStream(); bmp.SaveJpeg( ms, (int)element.ActualWidth, (int)element.ActualHeight, 0, 100); ms.Seek(0, SeekOrigin.Begin); var lib = new MediaLibrary(); var filePath = string.Format(title + ".jpg"); lib.SavePicture(filePath, ms); MessageBox.Show( "Saved in your media library!", "Done", MessageBoxButton.OK); } catch { MessageBox.Show( "There was an error. Please disconnect your phone from the computer before saving.", "Cannot save", MessageBoxButton.OK); } } This method can save any FrameworkElement. Typically I use it to save a whole page, but you can pass any other element to it. On line 7, we create a new WriteableBitmap. This excellent class can render a visual tree into a bitmap. Note that for even more features, you can use the great WriteableBitmapEx class library (which is open source). On lines 9 to 16, we save the WriteableBitmap to a MemoryStream. The only format supported by default is JPEG, however it is possible to convert to other formats with the ImageTools library (also open source). Lines 18 to 20 save the picture to the Windows Phone device’s media library. Using the image To retrieve the image, simply launch the Pictures library on the phone. The image will be in Saved Pictures. From here, you can share the image (by email, for instance), or synchronize it with the PC using the Zune software. Saving to other platforms It is of course possible to save to other platforms than the media library. For example, you can send the image to a web service, or save it to the isolated storage on the device. To do this, instead of using a MemoryStream, you can use any other stream (such as a web request stream, or a file stream) and save to that instead. Hopefully this code will be helpful to you! Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Get Your Enterprise Working With Oracle On Track Communication 1.0

    - by Josh Lannin
    The On Track Development team is very pleased to announce that today On Track is available for our customers to download and evaluate.  To learn more about what On Track does start with our whitepaper and datasheet.   If you are a developer, take a look at our documentation and samples posted to our OTN page. For this first blog post, I’ll be speaking to several notable points about our product. Graceful Escalation via Conversations: On Track addresses the “Collaboration Problem” through a single guiding principle – graceful escalation – within the construct of a Conversation. In On Track, collaboration is based on a context (called a “Conversation”) that gracefully escalates in form, structure, and content, as dictated by the particular needs of a given collaboration.  Within that context, On Track provides a rich set of tools to choose from.  These tools provide for communication, coordination, content management, organization, decision making, and analysis -- all essential aspects of collaboration, but not all of them are essential all of the time.  Every collaborative interaction will evolve differently.  Some will evolve to represent work spreading over the course of years and involving a large, distributed team, while others may involve few people and not evolve at all.  Regardless, all collaborative contexts are built from the same parts, utilize the same concepts, and start the same way.  The principle of graceful escalation is that you only use the tools and structure you need; so you only incur the complexity you need. Purposeful Collaboration: Through application integration, On Track Conversations bring enterprise application users the communication and collaboration capabilities required to complete business process.  By association with specific processes or business objects conversations extend the possible interactions and broaden participation to internal or external non-application users and provide a sophisticated interaction experience, all the while enhancing the data set within the owning application.  Purposeful collaboration not only needs to happen in the context of applications, it must support a full range of real-time and long-running interactions to provide the greatest value. Multi Client, Multi Modal: This On Track 1.0 product release includes the same day availability of  multiple clients, including iPhone and iPad applications which are now available on the Apple Store, a fully capable and accessible Outlook Add-In, along with our browser web client.  With each client we have sought to leverage the strengths of each unique device- our iPhone client supports picture and voice posts, the iPad is optimized for meeting room situations and document viewing, and our Outlook add-in allows you to take emails in context and bring them into On Track.  In addition to supporting a diverse array of clients, On Track provides a unified multi modal experience support starting with basic messages moving through to integrated documents with live annotations, snapshots, application sharing, and voice. Next Generation Web Architecture: We believe On Track will help move the bar higher for what users can expect from all web applications, most notably ones that involve real-time activity.  On Track is built from the ground up with an innovative, real-time architecture that leverages the extensive push capabilities of our server.  Whether you are receiving a new message, viewing where crowds of people are collaborating, or doing live annotation on a document with a set of people, that information comes to you immediately without refreshes or moving back and forth between pages.  We’ve leveraged this core architecture across the product experience and raised the user experience bar for this type of application.  As well these capabilities are based on open standards and protocols, and are fully extensible by anyone- enabling sophisticated integrations to be created with a wide variety of both legacy and next-generation applications. Agile Product Development: As a product team we operate using continuous feedback and modified agile development methodologies.  We have thousands of active internal Oracle users who have helped pilot our product for critical business functions, and the On Track product development team uses our product as our primary vehicle for all our collaboration.  Additionally we been working with early access customers who are adopting our technology and providing us valuable feedback - which our process has rapidly realized in improvements to our software.  On Track agility extends to our server as well, which is built to scale, and is very simple to install and configure. We are pleased to make this product announcement and encourage you to join us on Facebook or follow us on Twitter, as well as checking back here for the latest product information.

  • How to Make the Gnome Panels in Ubuntu Totally Transparent

    - by The Geek
    We all love transparency, since it makes your desktop so beautiful and lovely—so today we’re going to show you how to apply transparency to the panels in your Ubuntu Gnome setup. It’s an easy process, and here’s how to do it. This article is the first part of a multi-part series on how to customize the Ubuntu desktop, written by How-To Geek reader and ubergeek, Omar Hafiz. Making the Gnome Panels Transparent Of course we all love transparency, It makes your desktop so beautiful and lovely. So you go for enabling transparency in your panels , you right click on your panel, choose properties, go to the Background tab and make your panel transparent. Easy right? But instead of getting a lovely transparent panel, you often get a cluttered, ugly panel like this: Fortunately it can be easily fixed, all we need to do is to edit the theme files. If your theme is one of those themes that came with Ubuntu like Ambiance then you’ll have to copy it from /usr/share/themes to your own .themes directory in your Home Folder. You can do so by typing the following command in the terminal cp /usr/share/themes/theme_name ~/.themes Note: don’t forget to substitute theme_name with the theme name you want to fix. But if your theme is one you downloaded then it is already in your .themes folder. Now open your file manager and navigate to your home folder then do to .themes folder. If you can’t see it then you probably have disabled the “View hidden files” option. Press Ctrl+H to enable it. Now in .themes you’ll find your previously copied theme folder there, enter it then go to gtk-2.0 folder. There you may find a file named “panel.rc”, which is a configuration file that tells your panel how it should look like. If you find it there then rename it to “panel.rc.bak”. If you don’t find don’t panic! There’s nothing wrong with your system, it’s just that your theme decided to put the panel configurations in the “gtkrc” file. Open this file with your favorite text editor and at the end of the file there is line that looks like this “include “apps/gnome-panel.rc””. Comment out this line by putting a hash mark # in front of it. Now it should look like this “# include “apps/gnome-panel.rc”” Save and exit the text editor. Now change your theme to any other one then switch back to the one you edited. Now your panel should look like this: Stay tuned for the second part in the series, where we’ll cover how to change the color and fonts on your panels.

  • MIX 2010 Covert Operations Day 3

    - by GeekAgilistMercenary
    I rolled over to the Mandalay for breakfast.  There I met a couple guys that were really excited about the new Windows 7 Phone.  They, as I, are also hopeful that the phone really gets a big push and some penetration into the market.  Not because we don’t like any other of the phones, but because this phone is so much better in many ways.  From a developer's perspective creating applications in Windows 7 Mobile will be vastly superior in ease, capabilities, and other aspects.  The architectural, existing code base, examples, and provisions to create things on the 7 Mobile Device are already existing as of RIGHT NOW.  There is no reason, except for fickle market conditions, for this phone to not just explode onto the market.  But alas, I won't hold my breath. Day three keynote had a whole new slew of things provided.  It also seemed that things got a lot more technical on this second keynote.  The oData was one of the very technical bits, yet it included almost no code.  Starting with a Netflix example and all the way to the Codename "Dallas" effort the oData Services provide some expansive possibilities. A mash up going 4 ways was then shown for finding a movie, finding local places to have a viewing, and information about the movie and were to prospectively find and buy additional movie bits.  The display was of course, in a Windows 7 Mobile device with literally a click to view each set of data.  The backend and the front end of this was beautifully smooth. The Dallas Project has a lot of potential for analytics in dashboard and scorecard creation also.  If there is a need or reason to provide data to a vast and wide range of clients, Dallas is a prime example of how to do that. Azure Clouds After the main keynote I checked out (while developing a working WPF & Silverlight Application for work) the session on deploying ASP.NET Applications, services, etc, into the cloud.  The session was pretty good, but I'll admit I got a little unfocused from it a few times.  It is after all hard to do two things at one time. I did take note that the cloud still is a multiple step process for deploying to.  This is a good thing and a bad thing.  There needs to be more checks and verifications when deploying something into the cloud just for technical reasons.  However, I feel that there should be some streamlining to the process.  Going back and forth between web and Visual Studio as the interface also seems kind of clunky.  Deployment should be able to be completed from within Visual Studio in my perspective.  Overall, the cloud is getting more and more impressive in function as well as theory. That's it from me so far on the third day of MIX.  I'll be note taking and studying hard to have more good tidbits to provide. Thanks for reading, if you're curious about more of my writing, check out this original entry at my other blog Agilist Mercenary.

  • "Why We Chose Fusion CRM" by Vikas Bhambri, Managing Partner, The Athene Group

The company has accomplished a lot in ten years overcoming a number of hurdles and challenges to have grown organically to a 150+ person global company with offices in the US, UK, and India and customers in the US, Canada, and Europe. Now more than ever with the current global landscape from an economic and competitive standpoint it was vital that we make some changes to remain successful for the next ten years. There were two key initiatives that we discussed internally that would enable us to successfully accomplish this – collaboration and the concept of “insight to action”. With our existing Oracle CRM On Demand platform we had components of this but not the full depth and breadth that we were looking for. When we started to discuss Fusion CRM we immediately saw several next generation tools that would embrace these two objectives. For a consulting and development organization the collaboration required between business development and consulting delivery is as important as the collaboration required during the projects between the project delivery and account management teams. The Activity Streams functionality in Fusion CRM immediately addressed the communication of key discussion topics and exchanges around our clients. Of course when we saw the Oracle Social Network (which is part of our Fusion CRM roadmap) we were blown away. The combination OSN and our CRM is going to make us more effective as we discuss and work cohesively on client engagements – ensuring mutual success for both Athene and our clients. When we looked at “insight to action” we saw that we had a great platform when folks were at their desks, unfortunately a lot of our business development and consulting folks are on the road. The Fusion Mobile Sales and Fusion Outlook Desktop provide information to our teams when they are on the go. So that they can provide real-time information and react to real-time information provided by their peers. We are in the early stages of our transformative experience with Fusion CRM but we believe the platform along with our people and processes are going to help us achieve our goals in the future.

  • Visual Studio Extensions

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/18/visual-studio-extensions.aspxAs a product, Visual Studio has been around for a long time. In fact, it’s been 18 years since the first Visual Studio product was launched. In that time, there have been some major changes but perhaps the most important (or at least influential) changes for the course of the product have been in the last few years. While we can argue over what was and wasn’t an important change or what has and hasn’t changed, I want to talk about what I think is the single most important change Microsoft has made to Visual Studio. Specifically, I’m referring to the Visual Studio Gallery (first introduced in Visual Studio 2010) and the ability for third-parties to easily write extensions which can add new functionality to Visual Studio or even change existing functionality. I know Visual Studio had this ability before the Gallery existed, but it was expensive (both from a financial and development resource) perspective for a company or individual to write such an extension. The Visual Studio Gallery changed all of that. As of today, there are over 4000 items in the Gallery. Microsoft itself has over 100 items in the Gallery and more are added all of the time. Why is this such an important feature? Simply put, it allows third-parties (companies such as JetBrains, Telerik, Red Gate, Devart, and DevExpress, just to name a few) to provide enhanced developer productivity experiences directly within the product by providing new functionality or changing existing functionality. However, there is an even more important function that it serves. It also allows Microsoft to do the same. By providing extensions which add new functionality or change existing functionality, Microsoft is not only able to rapidly innovate on new features and changes but to also get those changes into the hands of developers world-wide for feedback. The end result is that these extensions become very robust and often end up becoming part of a later product release. An excellent example of this is the new CodeLens feature of Visual Studio 2013. This is, perhaps, the single most important developer productivity enhancement released in the last decade and already has huge potential. As you can see, out of the box CodeLens supports showing you information about references, unit tests and TFS history.   Fortunately, CodeLens is also accessible to Visual Studio extensions, and Microsoft DevLabs has already written such an extension to show code “health.” This extension shows different code metrics to help make sure your code is maintainable. At this point, you may have already asked yourself, “With over 4000 extensions, how do I find ones that are good?” That’s a really good question. Fortunately, the Visual Studio Gallery has a ratings system in place, which definitely helps but that’s still a lot of extensions to look through. To that end, here is my personal list of favorite extensions. This is something I started back when Visual Studio 2010 was first released, but so much has changed since then that I thought it would be good to provide an updated list for Visual Studio 2013. These are extensions that I have installed and use on a regular basis as a developer that I find indispensible. This list is in no particular order. NuGet Package Manager for Visual Studio 2013 Microsoft CodeLens Code Health Indicator Visual Studio Spell Checker Indent Guides Web Essentials 2013 VSCommands for Visual Studio 2013 Productivity Power Tools (right now this is only for Visual Studio 2012, but it should be updated to support Visual Studio 2013.) Everyone has their own set of favorites, so mine is probably not going to match yours. If there is an extension that you really like, feel free to leave me a comment!

  • Analytics in an Omni-Channel World

    - by David Dorf
    Retail has been around ever since mankind started bartering.  The earliest transactions were very specific to the individuals buying and selling, then someone had the bright idea to open a store.  Those transactions were a little more generic, but the store owner still knew his customers and what they wanted.  As the chains rolled out, customer intimacy was sacrificed for scale, and retailers began to rely on segments and clusters.  But thanks to the widespread availability of data and the technology to convert said data into information, retailers are getting back to details. The retail industry is following a maturity model for analytics that is has progressed through five stages, each delivering more value than the previous. Store Analytics Brick-and-mortar retailers (and pure-play catalogers as well) that collect anonymous basket-level data are able to get some sense of demand to help with allocation decisions.  Promotions and foot-traffic can be measured to understand marketing effectiveness and perhaps focus groups can help test ideas.  But decisions are influenced by the majority, using faceless customer segments and aggregated industry data points.  Loyalty programs help a little, but in many cases the cost outweighs the benefits. Web Analytics The Web made it much easier to collect data on specific, yet still anonymous consumers using cookies to track visits. Clickstreams and product searches are analyzed to understand the purchase journey, gauge demand, and better understand up-selling opportunities.  Personalization begins to allow retailers target market consumers with recommendations. Cross-Channel Analytics This phase is a minor one, but where most retailers probably sit today.  They are able to use information from one channel to bolster activities in another. However, there are technical challenges combining data silos so its not an easy task.  But for those retailers that are able to perform analytics on both sources of data, the pay-off is pretty nice.  Revenue per customer begins to go up as customers have a better brand experience. Mobile & Social Analytics Big data technologies are enabling a 360-degree view of the customer by incorporating psychographic data from social sites alongside traditional demographic data.  Retailers can track individual preferences, opinions, hobbies, etc. in order to understand a consumer's motivations.  Using mobile devices, consumers can interact with brands anywhere, anytime, accessing deep product information and reviews.  Mobile, combined with a loyalty program, presents an opportunity to put shopping into geographic context, understanding paths to the store, patterns within the store, and be an always-on advertising conduit. Omni-Channel Analytics All this data along with the proper technology represents a new paradigm in which the clock is turned back and retail becomes very personal once again.  Rich, individualized data better illuminates demand, allows for highly localized assortments, and helps tailor up-selling.  Interactions with all channels help build an accurate profile of each consumer, and allows retailers to tailor the retail experience to meet the heightened expectations of today's sophisticated shopper.  And of course this culminates in greater customer satisfaction and business profitability.

  • Working for free?

    - by Jonny
    I came across this article Work for Free that got me thinking. The goal of every employer is to gain more value from workers than the firm pays out in wages; otherwise, there is no growth, no advance, and no advantage for the employer. Conversely, the goal of every employee should be to contribute more to the firm than he or she receives in wages, and thereby provide a solid rationale for receiving raises and advancement in the firm. I don't need to tell you that the refusenik didn't last long in this job. In contrast, here is a story from last week. My phone rang. It was the employment division of a major university. The man on the phone was inquiring about the performance of a person who did some site work on Mises.org last year. I was able to tell him about a remarkable young man who swung into action during a crisis, and how he worked three 19-hour days, three days in a row, how he learned new software with diligence, how he kept his cool, how he navigated his way with grace and expertise amidst some 80 different third-party plug-ins and databases, how he saw his way around the inevitable problems, how he assumed responsibility for the results, and much more. What I didn't tell the interviewer was that this person did all this without asking for any payment. Did that fact influence my report on his performance? I'm not entirely sure, but the interviewer probably sensed in my voice my sense of awe toward what this person had done for the Mises Institute. The interviewer told me that he had written down 15 different questions to ask me but that I had answered them all already in the course of my monologue, and that he was thrilled to hear all these specifics. The person was offered the job. He had done a very wise thing; he had earned a devotee for life. The harder the economic times, the more employers need to know what they are getting when they hire someone. The job applications pour in by the buckets, all padded with degrees and made to look as impressive as possible. It's all just paper. What matters today is what a person can do for a firm. The resume becomes pro forma but not decisive under these conditions. But for a former boss or manager to rave about you to a potential employer? That's worth everything. What do you think? Has anyone here worked for free? If so, has it benefited you in any way? Why should(nt) you work for free (presuming you have the money from other means to keep you going)? Can you share your experience? Me, I am taking a year out of college and haven't gotten a degree yet so that's probably why most of my job applications are getting ignored. So im thinking about working for free for the experience?

  • Is a university education really worth it for a good programmer?

    - by Jon Purdy
    The title says it all, but here's the personal side of it: I've been doing design and programming for about as long as I can remember. If there's a programming problem, I can figure it out. (Though admittedly StackOverflow has allowed me to skip the figuring out and get straight to the doing in many instances.) I've made games, esoteric programming languages, and widgets and gizmos galore. I'm currently working on a general-purpose programming language. There's nothing I do better than programming. However, I'm just as passionate about design. Thus when I felt leaving high school that my design skills were lacking, I decided to attend university for New Media Design and Imaging, a digital design-related major. For a year, I diligently studied art and programmed in my free time. As the next year progressed, however, I was obligated to take fewer art and design classes and more technical classes. The trouble was of course that these classes were geared toward non-technical students, and were far beneath my skill level at the time. No amount of petitioning could overcome the institution's reluctance to allow me to test out of such classes, and the major offered no promise for any greater challenge in the future, so I took the extreme route: I switched into the technical equivalent of the major, New Media Interactive Development. A lot of my credits moved over into the new major, but many didn't. It would have been infeasible to switch to a more rigorous technical major such as Computer Science, and having tutored Computer Science students at every level here, I doubt I would be exposed to anything that I haven't already or won't eventually find out on my own, since I'm so involved in the field. I'm now on track to graduate perhaps a year later than I had planned, which puts a significant financial strain on my family and my future self. My schedule continues to be bogged down with classes that are wholly unnecessary for me to take. I'm being re-introduced to subjects that I've covered a thousand times over, simply because I've always been interested in it all. And though I succeed in avoiding the cynical and immature tactic of failing to complete work out of some undeserved sense of superiority, I'm becoming increasingly disillusioned by the lack of intellectual stimulation. Further, my school requires students to complete a number of quarters of co-op work experience proportional to their major. My original major required two quarters, but my current requires three, delaying my graduation even more. To top it all off, college is putting a severe strain on my relationship with my very close partner of a few years, so I've searched diligently for co-op jobs in my area, alas to no avail. I'm now in my third year, and approaching that point past which I can no longer handle this. Either I keep my head down, get a degree no matter what it takes, and try to get a job with a company that will pay me enough to do what I love that I can eventually pay off my loans; or I cut my losses now, move wherever there is work, and in six months start paying off what debt I've accumulated thus far. So the real question is: is a university education really more than just a formality? It's a big decision, and one I can't make lightly. I think this is the appropriate venue for this kind of question, and I hope it sticks around for the sake of others who might someday find themselves in similar situations. My heartfelt thanks for reading, and in advance for your help.

  • New Working Environment Starting November

    - by Jenson
    Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 This is actually a post dated update. After I’ve been working in the private sectors for so many years (the 2 years when I was working as IT trainer in a secondary school is not counted, as I was working under a contract with a private IT training agency), I’ve decided to try my luck into public sector. And fortunately, I passed the interview and I was offered a position of Web Administrator in a government statutory board, that’s Agency for Science, Technology and Research (of Singapore). During my previous employment with a Japanese MNC (multinational company), it was a totally new environment for me, as I had never worked for a Japanese company before, but the first time I work for Japanese company also gave me the very first nightmare I have with them, and vowed not to work for them anymore, and any other Japanese companies. No doubt I have freedom of choosing the tools and methods I wish to use for the projects, but the project management is simply too messy and out of order. And a lot of time, I don’t find that everyone is working as a team, more like achieving their own goals. Accountability for project is not shared, all lumped onto the shoulders of the developer in charge (they called it Software Engineer). I was working on a windows based .NET project, which I already voiced out that it’s not manageable by just 1 software engineer, but it seems like nobody cares, even the one who propose the solution to customer doesn’t care much. What he cares is whether you deliver the project on time so that he can please his customer and the senior management of his good work. Too many stories to tell, and I just simple doesn’t want to talk too much on this as it has already became the past to me. With my new title with the government agency, I hope to contribute my best to them, while learning as much as I can. I will share whatever I can on technologies, methodologies, and etc whichever I’m allowed and permitted to (of course, for those non-work-related stuff, I would be glad to share with you without much hesitation). Thank you! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • What DX level does my graphics card support? Does it go to 11?

    - by Daniel Moth
    Recently I run into a situation that I have run into quite a few times. Someone encounters a machine and the question arises: "Is there a DirectX 11 card in this machine?". Typically the reason you are interested in that is because cards with DirectX 11 drivers fully support DirectCompute (and by extension C++ AMP) for GPGPU programming. The driver specifically is WDDM (1.1 on Windows 7 and Windows 8 introduces WDDM 1.2 with cool new capabilities). There are many ways for figuring out if you have a DirectX11 card, so here are the approaches that you can use, with a bonus right at the end of the post. Run DxDiag WindowsKey + R, type DxDiag and hit Enter. That is the DirectX diagnostic tool, which unfortunately, only tells you on the "System" tab what is the highest version of DirectX installed on your machine. So if it reports DirectX 11, that doesn't mean you have a DX11 driver! The "Display" tab has a promising "DDI version" label, but unfortunately that doesn't seem to be accurate on the machines I've tested it with (or I may be misinterpreting its use). Either way, this tool is not the one you want for this purpose, although it is good for telling you the WDDM version among other things. Use the Microsoft hardware page There is a Microsoft Windows 7 compatibility center, that lists all hardware (tip: use the advanced search) and you could try and locate your device there… good luck. Use Wikipedia or the hardware vendor's website Use the Wikipedia page for the vendor cards, for both nvidia and amd. Often this information will also be in the specifications for the cards on the IHV site, but is is nice that wikipedia has a single page per vendor that you can search etc. There is a column in the tables for API support where you can see the DirectX version. Check if it is one of these recommended DX11 cards You may not have a DirectX 11 card and are interested in purchasing one. While I am in no position to make recommendations, I will list here some cards from two big IHVs that we know are DirectX 11 capable. Some AMD (aka ATI) cards Low end, inexpensive DX11 hardware: Radeon 5450, 5550, 6450, 6570 Mid range (decent perf, single precision): Radeon 5750, 5770, 6770, 6790 High end (capable of double precision): Radeon 5850, 5870, 6950, 6970 Single precision APUs: AMD E-Series APUs AMD A-Series APUs Some NVIDIA cards Low end, inexpensive DX11 hardware: GeForce GT430, GT 440, GT520, GTS 450 Quadro 400, 600 Mid-range (decent perf, single precision): GeForce GTX 460, GTX 550 Ti, GTX 560, GTX 560 Ti Quadro 2000 High end (capable of double precision): GeForce GTX 480, GTX 570, GTX 580, GTX 590, GTX 595 Quadro 4000, 5000, 6000 Tesla C2050, C2070, C2075 Get the DirectX SDK and run DirectX Caps Viewer Download and install the June 2010 DirectX SDK. As part of that you now have the DirectX Capabilities Viewer utility (find it in your start menu by searching for "DirectX Caps Viewer", the filename is DXCapsViewer.exe). It will list all your devices (emulated, and real hardware ones) under the first node. Expand the hardware entries and then expand again the Direct3D 11 folder. If you see D3D_FEATURE_LEVEL_11_ under that, then your card supports feature level 11 which means it supports DirectCompute and C++ AMP. In the following screenshot of one of my old laptops, the card only goes to feature level 10. Run a utility from the web that just tells you! Of course, writing some C++ AMP code that enumerates accelerators and lists the ones that are capable is trivial. However that requires that you have redistributed the runtime, so a more broadly applicable approach is to use the DX APIs directly to enumerate the DX11 capable cards. That is exactly what the development lead for C++ AMP has done and he describes and shares that utility at this post. Comments about this post by Daniel Moth welcome at the original blog.

  • How the number of indexes built on a table can impact performances?

    - by Davide Mauri
    We all know that putting too many indexes (I’m talking of non-clustered index only, of course) on table may produce performance problems due to the overhead that each index bring to all insert/update/delete operations on that table. But how much? I mean, we all agree – I think – that, generally speaking, having many indexes on a table is “bad”. But how bad it can be? How much the performance will degrade? And on a concurrent system how much this situation can also hurts SELECT performances? If SQL Server take more time to update a row on a table due to the amount of indexes it also has to update, this also means that locks will be held for more time, slowing down the perceived performance of all queries involved. I was quite curious to measure this, also because when teaching it’s by far more impressive and effective to show to attended a chart with the measured impact, so that they can really “feel” what it means! To do the tests, I’ve create a script that creates a table (that has a clustered index on the primary key which is an identity column) , loads 1000 rows into the table (inserting 1000 row using only one insert, instead of issuing 1000 insert of one row, in order to minimize the overhead needed to handle the transaction, that would have otherwise ), and measures the time taken to do it. The process is then repeated 16 times, each time adding a new index on the table, using columns from table in a round-robin fashion. Test are done against different row sizes, so that it’s possible to check if performance changes depending on row size. The result are interesting, although expected. This is the chart showing how much time it takes to insert 1000 on a table that has from 0 to 16 non-clustered indexes. Each test has been run 20 times in order to have an average value. The value has been cleaned from outliers value due to unpredictable performance fluctuations due to machine activity. The test shows that in a  table with a row size of 80 bytes, 1000 rows can be inserted in 9,05 msec if no indexes are present on the table, and the value grows up to 88 (!!!) msec when you have 16 indexes on it This means a impact on performance of 975%. That’s *huge*! Now, what happens if we have a bigger row size? Say that we have a table with a row size of 1520 byte. Here’s the data, from 0 to 16 indexes on that table: In this case we need near 22 msec to insert 1000 in a table with no indexes, but we need more that 500msec if the table has 16 active indexes! Now we’re talking of a 2410% impact on performance! Now we can have a tangible idea of what’s the impact of having (too?) many indexes on a table and also how the size of a row also impact performances. That’s why the golden rule of OLTP databases “few indexes, but good” is so true! (And in fact last week I saw a database with tables with 1700bytes row size and 23 (!!!) indexes on them!) This also means that a too heavy denormalization is really not a good idea (we’re always talking about OLTP systems, keep it in mind), since the performance get worse with the increase of the row size. So, be careful out there, and keep in mind the “equilibrium” is the key world of a database professional: equilibrium between read and write performance, between normalization and denormalization, between to few and too may indexes. PS Tests are done on a VMWare Workstation 7 VM with 2 CPU and 4 GB of Memory. Host machine is a Dell Precsioni M6500 with i7 Extreme X920 Quad-Core HT 2.0Ghz and 16Gb of RAM. Database is stored on a SSD Intel X-25E Drive, Simple Recovery Model, running on SQL Server 2008 R2. If you also want to to tests on your own, you can download the test script here: Open TestIndexPerformance.sql

  • Persevering & Friday Night Big Ideas

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein, Oracle Midsize Programs Every successful company, personal accomplishment, and philanthropic endeavor starts with one good idea. I have my best ideas on Friday evenings. The creative side of my brain is stimulated by end of week endorphins. Free thinking. Anything is possible. But, as my kids love to remind me, most of Dad's Friday Night Big Ideas (FNBIs) fizzle on the drawing board. Usually there's one barrier blocking the way that seems insurmountable by noon on Monday. For example, trekking the 486 mile Colorado Trail is on my bucket list. Since I have a job, I'll have to do it in bits and pieces--day hikes, weekends, and a vacation week here and there. With my trick neck, backpacking is not an option. How to survive equip myself for overnight backcountry travel was that one seemingly insurmountable barrier.  Persevering Lewis and Clark wouldn't have given up so I explored options and, as I blogged about back in December, I had an FNBI to hire llamas to carry my load. Last weekend, that idea came to fruition. Early Saturday morning, I met up with Bill, the owner of Antero Llamas, for an overnight training expedition along segment 14 of the Colorado Trail with a string of twelve llamas. It was a crash course on learning how to saddle, load, pasture, and mediate squabbles. Amazingly, we left the trailhead with me, the complete novice, at the lead. Instead of trying to impart three decades of knowledge on me in two days, Bill taught me two things: "Go With the Flow" and "Plan B". It worked. There were times I would be lost in thought for long stretches of time until one snort would remind me that I had a string of twelve llamas trailing behind. A funny thing happened along the trail... Up until last Saturday, my plan had been to trek all 28 segments of the trail east to west and sequentially. Out of some self-imposed sense of decorum. That plan presented myriad logistical challenges such as impassable snow pack on the Continental Divide when segment 6 is up next. On Sunday, as we trekked along the base of 14,000 ft peaks, I applied Bill's llama handling philosophy to my quest and came up with a much more realistic and enjoyable strategy for achieving my goal.  Seize opportunities to hike regardless of order. Define my own segments. Go west to east for awhile if it makes more sense. Let the llamas carry more creature comforts. Chill out.  I will still set foot on all 486 miles of the trail. Technically, the end result will be the same.And I and my traveling companions--human and camelid--will enjoy the journey more. Much more. Got Big Ideas of Your Own? Check out Tongal.

  • Tweeting about Oracle Applications Usability: Points to Consider

    - by ultan o'broin
    Here are a few pointers to anyone interested in tweeting about Oracle Applications usability or user experience (UX). These are based on my own experiences and practice, and may not necessarily reflect the views of Oracle, of course (touché, see the footer). If you are an Oracle employee and tweet about our offerings, then read up and follow the corporate social media policy. For the record, I tweet under the following account names: @ultan, @localization, @gamifyOracle, and @usableapps. The last two are supposedly Oracle subject-dedicated, but I mix it up on occassion. Fill out your Twitter account profile, and add a profile picture too. Disclose your interest. Don’t leave either the profile or image blank if you want to be taken seriously (or followed by me). Don’t tweet from a locked down Twitter account, as the message cannot be circulated to anyone who doesn't follow you. Open up the account if you really want to get that UX message out. Stay on message. The usable apps website, Misha Vaughan's VoX blog, and the Oracle Applications blog are good sources of UX messages and information, but you can find many other product team, individual, and corporate-wide sources with a little bit of searching. Set up a Google Alert with pertinent related keywords to get a daily digest of new information right in your inbox. Be original about it. Add your own insight and wit to the message, were relevant. Just circulating and RTing stock headlines adds no value to your effort or to the reader, and is somewhat lazy, in my opinion. Leave room for RTing of your tweet. So, don’t max out those 140 characters. Keep it under 130 if you want to be RTed without modification (or at all-I am not a fan of modifying tweets [MT], way too much effort for the medium). Remove articles and punctuation marks and use fragments, abbreviations, and so on at will to keep the tweet short enough, but leave keywords intact, as people search on those. Follow any Fusion UX Advocates who are on Twitter too (you can search for these names), and not just Oracle employees. Don't just follow people you like or think like you, or those who you think like you or are like-minded. Take a look at who is following or being followed by other tweeters and er, follow up. Create and socialize others to use an easily remembered or typed hashtag, or use what’s already popularized (for an event or conference, for example). We used #gamifyOracle for the applications UX gamification design jam, and other popular applications UX ones are #fusionapps and #usableapps (or at least I’m trying to popularize it). But, before you start the messaging, if you want to keep a record of the hashtag traffic, then set it up with an archiving service. Twitter’s own tweet lifespan is short. Don't mix up hashtags (#) with Twitter handles (@) that have the same name. Sending a tweet to @gamifyOracle will just be seen by @gamifyOracle (me) and any followers we have in common. Sending it to #gamifyOracle is seen by anyone following or searching for that hashtag. No dissing the competition. But there is no rule about not following them on Twitter to see the market reactions to Oracle announcements and this can even let you can tailor your own message accordingly. Don’t be boring. Mix it up a bit. Every 10th or so tweet, divert into other areas of interest, personal ones, even. No constant “I just received K+ in this and that” or “I just checked into wherever” on foursquare pouring into the Twittersteam, please. I just don’t care and will probably unfollow such people pretty quickly. And now, your Twitter tips and experiences with this subject? Them go in the comments...

  • Silverlight ProgressBar issues with Binding

    - by Chris Skardon
    The ProgressBar pretty much does what it says on the tin, displays progress, in a bar form (well, by default anyhow). It’s pretty simple to use: <ProgressBar Minimum="0" Maximum="100" Value="50"/> Gives you a progress bar with 50% of it filled: Easy! But of course, we’re wanting to use binding to change the value, again, pretty easy, have a ViewModel with a ‘Value’ in it, and bind: <ProgressBar Minimum="0" Maximum="100" Value="{Binding Value}"/> Spiffy, and whilst we’re at it, why not bind the Maximum value as well – after all, we can’t be sure of the size of the progress, and it’s a pain to have to work out the percentage (when the progress bar can do it for us): <ProgressBar Minimum="0" Maximum="MaximumValue" Value="{Binding Value}"/> Right, this will work absolutely fine. Or will it??? On the face of it, it looks good, and testing it shows no issues, until at one point we go from: Maximum = 100; Value = 90; to Maximum=60; Value=50; On the face of it not unreasonable. The problem is more obvious if we look at the states of the properties after each set (initially Maximum is set at 1, Value = 0): Code Maximum Value Value < Maximum Maximum = 100; 100 0 True Value = 90; 100 90 True Maximum = 60; 60 90 False Value = 50; 60 50 True Everything is good until the Value is less than the Maximum, at this point the Progress Bar breaks. That’s right, it no longer updates itself, it will always look 100% full. The simple solution – always ensuring you set Value before Maximum is fine unless you’re using a ProgressBar in a less controlled environment – where for example you’re setting a ‘container’ with both values at the same time. The example I have is in a DataTemplate, I have a DataTemplate for a BusyIndicator, (specifically the BusyContentTemplate). The binding works this way: <BusyIndicator BusyContent="{Binding BusyContent}" BusyContentTemplate="{Binding ProgressTemplate}"/> With the template as the ProgressBar defined above… I was setting my BusyContent like this: BusyContent = content; aaaaaand finally, ‘content’ is a class: public class ContentClass : INotifyPropertyChanged { //Obviously this is properly implemented… public double Maximum { get;set;} public double Value { get;set;} } Soooo… As I was replacing the BusyContent wholesale, the order of the binding being set was outside of my control, so – how to go about it? Basically? Fudge it. Modify the ContentClass to include a method: public void Update(double value, double max) { Value = value; Maximum = max; } and change where the setting is to be: BusyContent.Update(content.Value, content.Maximum); Thereby getting the order correct.. Obvious really. Meh :|
