  • How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

    - by Kris
    We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

    - by Gopinath
    Nokia released it’s first set of smartphones, Lumia 800 & Lumia 710,  powered by Microsoft’s Windows Phone OS few weeks ago in Europe. India being it’s one of the favourite markets, Nokia is all set to launch the Lumia on November 14 in New Delhi. Unlike Apple who releases iPhones in India very late, Nokia is planning to bring its flagship smart mobiles very early to Indian market.  This is a good move by Nokia to keep it’s existing market share that is continuously challenged by Android OS smart phones from various manufactures. Nokia Lumia 710 runs on version 7.5 of Windows Phone OS(nick named as Mango) with 512 MB RAM, 8 GB internal storage capacity, 3.7″ WVGA TFT display, WIFI, GPS,  and 5 MP camera. Price details of the phone is not available but to be competitive in the market it should be priced some where between 25,000 to 30,000. Lets wait two more days and we will get the full details after the press release on Nov 14th. source: nirmaltv This article titled,Nokia Lumia Windows Phones Coming To India On Nov 14, was originally published at Tech Dreams.

  • Asset and Work Management in Utilities: An Integrated Enterprise Success Story

    - by stephen.slade(at)oracle.com
    Jan 11 '11 Webcast: Utilities are turning to Oracle to deliver an integrated EAM platform that manages all of their assets from fleet to facilities and distribution to generation. Hear from solutions experts and from Sunflower Electric Power Corporation about how an integrated enterprise asset and work management system helped them deliver bottom line results Do you have different work management systems for generation, distribution, and transmission? Fleet maintenance? Facilities? Are you on the latest release of these products? Have you considered your options when the product is no longer supported? Do you struggle with integration and keeping the various systems "in balance"? Do you have trouble retrieving data from these disparate systems and getting an enterprise view of asset and work management operations? Utilities are challenged to better manage information on generation, transmission and distribution assets. Point solutions for Enterprise Asset Management (EAM) and Computerized Maintenance Management Systems (CMMS) are often effective as departmental solutions but have limited ability to deliver an enterprise solution with accessible business intelligence.

  • Portal and Content - Components, part 3 – Applied Customization Framework (4 of 7)

    - by Stefan Krantz
    Have you ever been challenged with the situation where your work task asks you to implement functionality in the WebCenter Portal and you browse through the Resource Catalog (Business Dictionary) and find the functionality you need. However when you get started there is small short comings and you ask your self- how can I re-use what is out of the box ca?- I wonder what code I need to use to produce the similar functions and include my new requirements?- Must I write a new taskflow? The answer to above questions are in many times answered with simply you can  do a taskflow customization to out-of-the-box taskflows. In this post I will help you understand how to do such customization. Best described is a 4 step process, see image flow below for illustration: Just to clarify few naming confusions that might occur when go through above process. Customization Role is a function within JDeveloper that will allow you to implement view and flow customizations to existing taskflows WebCenter Portal – Spaces Taskflow Customization Framework this technology scope do not only refer to WebCenter Spaces, this also include WebCenter Portal/Framework A taskflow customization do not overwrite or replace any code, it just creates an additional tip view of the taskflow in the MDS for the current application (WebCenter Portal or WebCenter Spaces) To sum up this simple procedure I also like to help you find your way around the main topic for this post series, this post series is focusing primarily on Content integration with WebCenter Portal, so where can I find content related taskflows in the WebCenter Libraries. The list below mention some useful locations to taskflows and each taskflow page fragments. Library Reference - WebCenter Document Library Service View Content Presenter Path: oracle.webcenter.doclib.view.jsf.taskflows.presenterTaskflow: contentPresenter.xml - The Content Presenter taskflowTaskflow: contentPresenterWizard.xml - The publishing wizard to select content, select template and preview including contributionDocument Manager Path: oracle.webcenter.doclib.view.jsf.taskflows.docManager Taskflow: documentManager.xml - The Document Manager taskflow which includes references to document management feature including browsing, download, uploading and viewing. For more information on Taskflow customizations please see following documentation:http://docs.oracle.com/cd/E23943_01/webcenter.1111/e10148/jpsdg_taskflows.htm#BACIEGJD

  • Game-a-Week One

    - by Matt Christian
    Anyone who chats with me on a semi-regular basis knows I am absolutely horrible at completing something from beginnning to end.  Often times I'll begin something, lose interest at some point, and end up moving onto the next thing.  For example, I have 1/2 a full game created, 1/3 of a novel written, and half of a model set created.  Needless to say, unless I have some sort of pressure to finish something I don't stick to it. Recently however one of my online buddies challenged me to create a simple game.  The start date was last Thursday and the final game needed to be delivered by this next Sunday (giving me just over a week).  However, I am going out of town this Friday so will need to deliver it by Thursday, giving me exactly 1 week to develop a game.  Here is what the game needed to include: The player should be able to shoot Shooting things should score points Sounds very simple, but given a single week to produce all art assets plus the game isn't an easy task.  So far I've developed: An animated Main Menu that loads via script files, allows the user to start a new game or exit the game The game is 3D and the player can move around the play area with an 'over-the-shoulder' camera HUD elements are drawn to display the player's current score When the player presses Esc they are shown a pause menu where they can resume the game by pressing Esc again, or quit the game by pressing Space There are also 2 items implemented that don't work perfectly: JigLibX physics library implementation On the main menu there is an arrow symbol that rotates to always point at your mouse I've got 2 days of development left so hopefully I can get collision working, some of the art cleaned up, and some more of the camera functionality working.  Also, I'll need to take some time to package the game up which hopefully shouldn't take too long.

  • What&rsquo;s in your wallet, er&hellip;Inbox?

    - by johndoucette
    Since my first UUCP operation in UNIX to deliver and receive an email, I have always been challenged to find the ultimate email organizer. About a year ago, I switched to a very simple process of managing email and have found the ultimate in organization. On the craziest of days with 250+ emails, I keep my inbox empty. Here is how I do it; First, start with the following folders in your mailbox; Inbox    Archive    FollowUp    Hold Of course, all inbound emails will start in the Inbox. As you work throughout the day, follow these steps to keep your inbox empty; Read the email. Are you responsible for any action? If you are and can do it immediately, then do it. If you need to do it later, move the email to the “FollowUp” folder If you are not responsible for any action, move it to the archive folder. Use Outlook’s search to find them when you need them. If you will need to reference the email later in the week or for a short term (week or two), then move the email to the “Hold” folder As your day progresses, frequently review the FollowUp folder and accomplish the task *Notes: If I am waiting for someone to do something for me, I keep it in the FollowUp folder. As I review the folder, I am constantly reminded that there is something I am waiting on – and can send a simple reminder by forwarding the original email. I sometimes send myself a “todo” email and park it in the FollowUp folder I like to know how many emails are in the folders so I set the “Show total number of items” property on the folder to show the amount of emails.

  • Oracle India Provides Choices For Students

    - by user769227
    For next year's graduating class of computer science and engineering students, the world is their oyster. I believe that in today's day and age the opportunities for graduates are truly endless. Many students have a misconception that Oracle is mainly a Database Company. While we certainly are leaders in the database space, there is so much more that we do. If you look a little bit deeper you will find we have business groups within Oracle creating technical solutions across all areas of the business world. I think that the opportunities available at Oracle can be those 'life changing' roles that students are looking for where they will learn, develop, be challenged and still have the opportunity to be themselves. What other company provides as many choices for students as Oracle. The range of business and technical solutions we provide is enormous.

  • Comb Over

    - by Tim Dexter
    Being some what follicly challenged, and to my wife's utter relief, the comb over is not something I have ever considered. The title is a tenuous reference to a formatting feature that Adobe offers in their PDF documents. The comb provides the ability to equally space a string of characters on a pre-defined form layout so that it fits neatly in the area. See the numbers above are being spaced correctly. Its not a function of the font but a property of the form field. For the first time, in a long time I had the chance to build a PDF template today to help out a colleague. I spotted the property and thought, hey, lets give it a whirl and see in Publisher supports it? Low and behold, Publisher handles the comb spacing in its PDF outputs. Exciting eh? OK, maybe not that exciting but I was very pleasantly surprise to see it working. I am reliably informed, by Leslie, BIP Evangelist and Tech Writer that, this feature was introduced from version 10.1.3.4.2 onwards. Official docs and no mention of comb overs here. Happy Combing!

  • Process Improvement and the Data Professional

    - by BuckWoody
    Don’t be afraid of that title – I’m not talking about Six Sigma or anything super-formal here. In many organizations, there are more folks in other IT roles than in the Data Professional area. In other words, there are more developers, system administrators and so on than there are the “DBA” role. That means we often have more to do than the time we need to do it. And, oddly enough, the first thing that is sacrificed is process improvement – the little things we need to do to make the day go faster in the first place. Then we get even more behind, the work piles up and…well, you know all about that. Earlier I challenged you to find 10-30 minutes a day to study. Some folks wrote back and asked “where do I start”? Well, why not be super-efficient and combine that time with learning how to make yourself more efficient? Try out a new scripting language, learn a new tool that automates things or find out ways others have automated their systems. In general, find out what you’re doing and how, and then see if that can be improved. It’s kind of like doing a performance tuning gig on yourself! If you’re pressed for time, look for bite-sized articles (like the ones I’ve done here for PowerShell and SQL Server) that you can follow in a “serial” fashion. In a short time you’ll have a new set of knowledge you can use to make your day faster. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Review of TechEd 2012 - so far

    - by Stefan Barrett
    Disclaimer: probably going to next years TechEd.  (but not 100% sure) As with most TechEd's, this is not one of the best - but it's not bad.  Some impressions so far: The food is not bad, through perhaps not as much choice as in previous years.  The snacks, while a bit limited, are at least available.  The alumni lounge is ok, through perhaps not as good as last years.  Wifi is a bit worse than previous years - not really working in the big room, and a bit sporadic in the rest of the building. The device seems to make a big difference - the iPad seems to connect the easiest, while the iPhone & Lumia 800 are really struggling.  The real problem is the content - not as developer focused as in previous years.  This shows up in a number of different ways, for example while there is a visual studio booth, there is not much sign of anybody from the language teams.  This is one of few TechEd's where I don't feel very surprised about anything - seen most of the developer stuff in previews. One example where I was surprised was the pre-conf on c++ - its been years since I did any c++, but based on that session perhaps I should start again. While there are sessions, I'm not finding my schedule very challenged. For each time-slot there only seems to 1, or rarely 2, interesting sessions.  The focus seems to be on windows 8, Azure and the phone, which while interesting (might give win8 a go), are not enough.

  • Keeping Your Employees Engaged Requires More Than Bright Shiny Objects

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein | Sr. Principal Product Marketing Director | Oracle Midsize Programs | @JimLein If you are experiencing the challenges of hiring and retaining the best talent then you understand how important it is to keep employees engaged. An engaged employee is "one who understands his/her place in the organization and fully comprehends how they contribute to and participate in the firm's execution of its Mission and Vision". It goes deeper than just what I call "bright shiny objects". During my ski bum days, all my boss at the ski shop had to do was say, "If you put all these boots away before noon you can make a few powder runs and come back for the afternoon rush". That's as bright and shiny as it gets. Pamela Stroko heads up Oracle's HCM Sales Enablement and Development and is Talent Management and Expert and Evangelist. Our Oracle Accelerate quarterly newsletter features a Q&A with Stroko on the Current State of Employee Engagement. Stroko provides perspective on how to keep employees engaged when hiring managers are challenged to find and retain top talent. Read the entire Q&A here. Click here to see the entire newsletter.

  • Constituent Experience Counts In Public Sector

    - by Michael Seback
      Businesses and government organizations are operating in an era of the empowered customer where service  and communication channels are challenged every day.  Consumers in the private sector have high expectations from purchasing gifts online, reading reviews on social sites, and expecting the companies they do business with to know and reward them.   In the Public Sector, constituents also expect government organizations to provide consistent and timely service across agencies and touch points.  Examples include requesting critical city services, applying for social assistance or reviewing insurance plans for a health insurance exchange. If an individual does not receive the services they need at the right time and place, it can create a dire situation – involving housing, food or healthcare assistance. Government organizations need to deliver a fast, reliable and personalized experience to constituents. Look at a few recent statistics from a Government focused survey: How do you define good customer service? 70 % improved services, 48% shortest time to provide information, 44% shortest time to resolve complaints What are ways/opportunities to improve customer service? 69% increased collaboration across agencies and 41% increased customer service channels Are you using data collected to make informed decisionsto improve customer service efforts? 39% data collection is limited, not used to improve decision making Source: Re-Imagining Customer Service in Government, 2012 Click here to see the highlights.  Would you like to get started – read Eight Steps to great constituent experiences for government.

  • Forcing an External Activation with Service Broker

    - by Davide Mauri
    In these last days I’ve been working quite a lot with Service Broker, a technology I’m really happy to work with, since it can give a lot of satisfaction. The scale-out solution one can easily build is simply astonishing. I’m helping a company to build a very scalable and – yet almost inexpensive – invoicing system that has to be able to scale out using commodity hardware. To offload the work from the main server to satellite “compute nodes” (yes, I’ve borrowed this term from PDW) we’re using Service Broker and the External Activator application available in the SQL Server Feature Pack. For those who are not used to work with SSB, the External Activation is a feature that allows you to intercept the arrival of a message in a queue right from your application code. http://msdn.microsoft.com/en-us/library/ms171617.aspx (Look for “Event-Based Activation”) In order to make life even more easier, Microsoft released the External Activation application that saves you even from writing even this code. http://blogs.msdn.com/b/sql_service_broker/archive/tags/external+activator/ The External Activator application can be configured to execute your own application so that each time a message – an invoice in my case – arrives in the target queue, the invoking application is executed and the invoice is calculated. The very nice feature of External Activator is that it can automatically execute as many configured application in order to process as many messages as your system can handle.  This also a lot of create a scale-out solution, leaving to the developer only a fraction of the problems that usually came with asynchronous programming. Developers are also shielded from Service Broker since everything can be encapsulated in Stored Procedures, so that – for them – developing such scale-out asynchronous solution is not much more complex than just executing a bunch of Stored Procedures. Now, if everything works correctly, you don’t have to bother of anything else. You put messages in the queue and your application, invoked by the External Activator, process them. But what happen if for some reason your application fails to process the messages. For examples, it crashes? The message is safe in the queue so you just need to process it again. But your application is invoked by the External Activator application, so now the question is, how do you wake up that app? Service Broker will engage the activation process only if certain conditions are met: http://msdn.microsoft.com/en-us/library/ms171601.aspx But how we can invoke the activation process manually, without having to wait for another message to arrive (the arrival of a new message is a condition that can fire the activation process)? The “trick” is to do manually with the activation process does: sending a system message to a queue in charge of handling External Activation messages: declare @conversationHandle uniqueidentifier; declare @n xml = N' <EVENT_INSTANCE>   <EventType>QUEUE_ACTIVATION</EventType>   <PostTime>' + CONVERT(CHAR(24),GETDATE(),126) + '</PostTime>   <SPID>' + CAST(@@SPID AS VARCHAR(9)) + '</SPID>   <ServerName>[your_server_name]</ServerName>   <LoginName>[your_login_name]</LoginName>   <UserName>[your_user_name]</UserName>   <DatabaseName>[your_database_name]</DatabaseName>   <SchemaName>[your_queue_schema_name]</SchemaName>   <ObjectName>[your_queue_name]</ObjectName>   <ObjectType>QUEUE</ObjectType> </EVENT_INSTANCE>' begin dialog conversation     @conversationHandle from service        [<your_initiator_service_name>] to service          '<your_event_notification_service>' on contract         [http://schemas.microsoft.com/SQL/Notifications/PostEventNotification] with     encryption = off,     lifetime = 6000 ; send on conversation     @conversationHandle message type     [http://schemas.microsoft.com/SQL/Notifications/EventNotification] (@n) ;     end conversation @conversationHandle; That’s it! Put the code in a Stored Procedure and you can add to your application a button that says “Force Queue Processing” (or something similar) in order to start the activation process whenever you need it (which should not occur too frequently but it may happen). PS I know that the “fire-and-forget” (ending the conversation without waiting for an answer) technique is not a best practice, but in this case I don’t see how it can hurts so I decided to stay very close to the KISS principle []

  • Async CTP (C# 5): How to make WCF work with Async CTP

    - by javarg
    If you have recently downloaded the new Async CTP you will notice that WCF uses Async Pattern and Event based Async Pattern in order to expose asynchronous operations. In order to make your service compatible with the new Async/Await Pattern try using an extension method similar to the following: WCF Async/Await Method public static class ServiceExtensions {     public static Task<DateTime> GetDateTimeTaskAsync(this Service1Client client)     {         return Task.Factory.FromAsync<DateTime>(             client.BeginGetDateTime(null, null),             ar => client.EndGetDateTime(ar));     } } The previous code snippet adds an extension method to the GetDateTime method of the Service1Client WCF proxy. Then used it like this (remember to add the extension method’s namespace into scope in order to use it): Code Snippet var client = new Service1Client(); var dt = await client.GetDateTimeTaskAsync(); Replace the proxy’s type and operation name for the one you want to await.

  • Accessing Server-Side Data from Client Script: Using WCF Services with jQuery and the ASP.NET Ajax Library

    Today's websites commonly exchange information between the browser and the web server using Ajax techniques - the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. which then processes the request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Two earlier articles - Accessing JSON Data From an ASP.NET Page Using jQuery and Using Ajax Web Services, Script References, and jQuery, looked at using both jQuery and the ASP.NET Ajax Library on the browser to initiate an Ajax request and both ASP.NET pages and Ajax Web Services as the entities on the web server responsible for servicing such Ajax requests. This article continues our examination of techniques for implementing lightweight Ajax scenarios in an ASP.NET website. Specifically, it examines how to use the Windows Communication Foundation, or WCF, to serve data from the web server and how to use both the ASP.NET Ajax Library and jQuery to consume such services from the client-side.

  • Forcing an External Activation with Service Broker

    - by Davide Mauri
    In these last days I’ve been working quite a lot with Service Broker, a technology I’m really happy to work with, since it can give a lot of satisfaction. The scale-out solution one can easily build is simply astonishing. I’m helping a company to build a very scalable and – yet almost inexpensive – invoicing system that has to be able to scale out using commodity hardware. To offload the work from the main server to satellite “compute nodes” (yes, I’ve borrowed this term from PDW) we’re using Service Broker and the External Activator application available in the SQL Server Feature Pack. For those who are not used to work with SSB, the External Activation is a feature that allows you to intercept the arrival of a message in a queue right from your application code. http://msdn.microsoft.com/en-us/library/ms171617.aspx (Look for “Event-Based Activation”) In order to make life even more easier, Microsoft released the External Activation application that saves you even from writing even this code. http://blogs.msdn.com/b/sql_service_broker/archive/tags/external+activator/ The External Activator application can be configured to execute your own application so that each time a message – an invoice in my case – arrives in the target queue, the invoking application is executed and the invoice is calculated. The very nice feature of External Activator is that it can automatically execute as many configured application in order to process as many messages as your system can handle.  This also a lot of create a scale-out solution, leaving to the developer only a fraction of the problems that usually came with asynchronous programming. Developers are also shielded from Service Broker since everything can be encapsulated in Stored Procedures, so that – for them – developing such scale-out asynchronous solution is not much more complex than just executing a bunch of Stored Procedures. Now, if everything works correctly, you don’t have to bother of anything else. You put messages in the queue and your application, invoked by the External Activator, process them. But what happen if for some reason your application fails to process the messages. For examples, it crashes? The message is safe in the queue so you just need to process it again. But your application is invoked by the External Activator application, so now the question is, how do you wake up that app? Service Broker will engage the activation process only if certain conditions are met: http://msdn.microsoft.com/en-us/library/ms171601.aspx But how we can invoke the activation process manually, without having to wait for another message to arrive (the arrival of a new message is a condition that can fire the activation process)? The “trick” is to do manually with the activation process does: sending a system message to a queue in charge of handling External Activation messages: declare @conversationHandle uniqueidentifier; declare @n xml = N' <EVENT_INSTANCE>   <EventType>QUEUE_ACTIVATION</EventType>   <PostTime>' + CONVERT(CHAR(24),GETDATE(),126) + '</PostTime>   <SPID>' + CAST(@@SPID AS VARCHAR(9)) + '</SPID>   <ServerName>[your_server_name]</ServerName>   <LoginName>[your_login_name]</LoginName>   <UserName>[your_user_name]</UserName>   <DatabaseName>[your_database_name]</DatabaseName>   <SchemaName>[your_queue_schema_name]</SchemaName>   <ObjectName>[your_queue_name]</ObjectName>   <ObjectType>QUEUE</ObjectType> </EVENT_INSTANCE>' begin dialog conversation     @conversationHandle from service        [<your_initiator_service_name>] to service          '<your_event_notification_service>' on contract         [http://schemas.microsoft.com/SQL/Notifications/PostEventNotification] with     encryption = off,     lifetime = 6000 ; send on conversation     @conversationHandle message type     [http://schemas.microsoft.com/SQL/Notifications/EventNotification] (@n) ;     end conversation @conversationHandle; That’s it! Put the code in a Stored Procedure and you can add to your application a button that says “Force Queue Processing” (or something similar) in order to start the activation process whenever you need it (which should not occur too frequently but it may happen). PS I know that the “fire-and-forget” (ending the conversation without waiting for an answer) technique is not a best practice, but in this case I don’t see how it can hurts so I decided to stay very close to the KISS principle []

  • Visual Studio Async CTP

    - by Daniel Moth
    While most of the buzz at the recent PDC here at Microsoft's headquarters has been about Windows Azure and Windows Phone, there is a truly noteworthy technology that as a .NET developer (of any kind of application) you should pay attention to, even in its early technology preview stage: Visual Studio Async CTP. I could provide many more direct links, but you do not need them: just visit the home page of this technology to download whitepapers, watch videos on how this technology integrates with C# and with VB, (through the new async and await language keywords) as well as videos on how the technology works under the covers (based largely on the Task Parallel Library). More importantly, download the actual bits (they install on top of your Visual Studio 2010), which include many samples. Get ready for a revolution in Asynchronous Programming with C# and Visual Basic. Comments about this post welcome at the original blog.

  • Semi-blocking Transformations in SQL Server Integration Services SSIS

    In a SSIS data flow, there are multiple types of transformations. On one hand you have synchronous and asynchronous transformations, but on the other hand you have non-blocking, semi-blocking and fully-blocking components. In this tip, Koen Verbeeck takes a closer look on the performance impact of semi-blocking transformations in SSIS. Can 41,000 DBAs really be wrong? Join 41,000 other DBAs who are following the new series from the DBA Team: the 5 Worst Days in a DBA’s Life. Part 3, As Corrupt As It Gets, is out now – read it here.

  • OpenJDK DIO Project Now Live! Java SE Embedded API Accessing Peripherals

    - by hinkmond
    The DIO project on OpenJDK is now live! For those who grew up in the 1970's and 1980's, you might remember Ronnie James Dio, lead singer of Black Sabbath after Ozzy was fired, and lead singer of his own band, Dio. Well, this DIO is not that Dio. This DIO is the OpenJDK Device I/O project which provides a Java-level API for accessing generic device peripherals on embedded devices, like your Raspberry Pi running Java SE Embedded software. See: OpenJDK DIO Project Here's a quote: + General Purpose Input/Output (GPIO) + Inter-Integrated Circuit Bus (I2C) + Universal Asynchronous Receiver/Transmitter (UART) + Serial Peripheral Interface If you're familiar with Pi4J, then you're going to like DIO. And, if you liked Ozzy, you probably liked Ronnie James Dio. This will probably make Robert Savage happy too. The part about DIO being live now, not the part about Dio replacing Ozzy, because everyone likes Ozzy. Hinkmond
