• 13 MORE Things from the Oracle Social Summit You Should Know

  - by Mike Stiles

  In our previous blog, we started giving those of you who couldn’t make it just a sampling of the valuable takeaways from the first annual Oracle Social Summit, held Nov 14 and 15 in Las Vegas. And while yes, 13 items is a pretty healthy sampling, we wanted to go the extra mile and give you 13 more, an indication of just how much great information came out of it.  Follow the arrow, and come on in as if you were there with us. 1. Weber Shandwick takes a 70/20/10 approach when advising clients how to allocate resources to paid social opportunities. 70% of spend should go toward paid opportunities the agency and client both know work, 20% should go toward paid social the agency knows works, and 10% should go toward experimentation. (Matt Dickman – Weber Shandwick) 2. By 2017, the technically competent CMO will spend more on IT than the CIO. (Gartner Study) 3. CIOs are focused on infrastructure. As the roles of the CMO and CIO continue coming together, those CIOs have to make a very conscious decision to get CMOs what they need. 4. It’s now harder for brands to differentiate based on product. The advantage will go to the brands that are successful in garnering customer trust. 5. More and more, enterprise software is going to start looking like the software consumers are used to seeing and using. 6. You will see brands prioritizing mobile and dropping investments in www, HTML, POS systems, etc. 7. The social graph has to be added to brands’ customer data for a more holistic view. Customers will give you the information you need if the reward is appropriate. 8. Viacom did a study that showed viewers are most honest on social. Not so much on surveys or other feedback vehicles. 9. How are you determining your influencers? Influence isn’t about reach. It’s about getting people to change behavior. 10. A mix of skills is becoming critically important in a social staff. It shouldn’t be a mixture of several disciplines, not just a bunch of “social experts.” 11. If senior management isn’t engaged, the social team is forced into guessing what might be considered a “success” by the C-suite. 12. Mobile customization will be getting big investments from brands in 2013. Brands need to provide shoppers utility, not just information. 75% will use mobile this holiday season to avoid in-store madness. 13. Data becomes information, information becomes insight, and insight becomes actionable. The Oracle Social Summit brought together brands, agencies, Oracle social experts and industry thought leaders to take a serious look at where social stands today, and where it’s headed in the near future. Given the speed of social’s evolution, attending such events (or at least reading nifty summary blogs) is a good investment in making sure your enterprise isn’t falling gradually behind.

• Open source adventures with... wait for it... Microsoft

  - by Jeff

  Last week, Microsoft announced that it was going to open source the rest of the ASP.NET MVC Web stack. The core MVC framework has been open source for a long time now, but the other pieces around it are also now out in the wild. Not only that, but it's not what I call "big bang" open source, where you release the source with each version. No, they're actually committing in real time to a public repository. They're also taking contributions where it makes sense. If that weren't exciting enough, CodePlex, which used to be a part of the team I was on, has been re-org'd to a different part of the company where it is getting the love and attention (and apparently money) that it deserves. For a period of several months, I lobbied to get a PM gig with that product, but got nowhere. A year and a half later, I'm happy to see it finally treated right. In any case, I found a bug in Razor, the rendering engine, before the beta came out. I informally sent the bug info to some people, but it wasn't fixed for the beta. Now, with the project being developed in the open, I was able to submit the issue, and went back and forth with the developer who wrote the code (I met him once at a meet up in Bellevue, I think), and he committed a fix. I tried it a day later, and the bug was gone. There's a lot to learn from all of this. That open source software is surprisingly efficient and often of high quality is one part of it. For me the win is that it demonstrates how open and collaborative processes, as light as possible, lead to better software. In other words, even if this were a project being developed internally, at a bank or something, getting stakeholders involved early and giving people the ability to respond leads to awesomeness. While there is always a place for big thinking, experience has shown time and time again that trying to figure everything out up front takes too long, and rarely meets expectations. This is a lesson that probably half of Microsoft has yet to learn, including the team I was on before I split. It's the reason that team still hasn't shipped anything to general availability. But I've seen what an open and iterative development style can do for teams, at Microsoft and other places that I've worked. When you can have a conversation with people, and take ideas and turn them into code quickly, you're winning. So why don't people like winning? I think there are a lot of reasons, and they can generally be categorized into fear, skepticism and bad experiences. I can't give the Web stack teams enough credit. Not only did they dream big, but they changed a culture that often seems immovable and hopelessly stuck. This is a very public example of this culture change, but it's starting to happen at every scale in Microsoft. It's really interesting to see in a company that has been written off as dead the last decade.

• Lessons Building KeyRef (a .NET developer learning Rails)

  - by Liam McLennan

  Just because I like to build things, and I like to learn, I have been working on a keyboard shortcut reference site. I am using this as an opportunity to improve my ruby and rails skills. The first few days were frustrating. Perhaps the learning curve of all the fun new toys was a bit excessive. Finally tonight things have really started to come together. I still don’t understand the rails built-in testing support but I will get there. Interesting Things I Learned Tonight RubyMine IDE Tonight I switched to RubyMine instead of my usual Notepad++. I suspect RubyMine is a powerful tool if you know how to use it – but I don’t. At the moment it gives me errors about some gems not being activated. This is another one of those things that I will get to. I have also noticed that the editor functions significantly differently to the editors I am used to. For example, in visual studio and notepad++ if you place the cursor at the start of a line and press left arrow the cursor is sent to the end of the previous line. In RubyMine nothing happens. Haml Haml is my favourite view engine. For my .NET work I have been using its non-union Mexican CLR equivalent – nHaml. Multiple CSS Classes To define a div with more than one css class haml lets you chain them together with a ‘.’, such as: .span-6.search_result contents of the div go here Indent Consistency I also learnt tonight that both haml and nhaml complain if you are not consistent about indenting. As a consequence of the move from notepad++ to RubyMine my haml views ended up with some tab indenting and some space indenting. For the view to render all of the indents within a view must be consistent. Sorting Arrays I guessed that ruby would be able to sort an array alphabetically by a property of the elements so my first attempt was: Application.all.sort {|app| app.name} which does not work. You have to supply a comparer (much like .NET). The correct sort is: Application.all.sort {|a,b| a.name.downcase <=> b.name.downcase} MongoMapper Find by Id Since document databases are just fancy key-value stores it is essential to be able to easily search for a document by its id. This functionality is so intrinsic that it seems that the MongoMapper author did not bother to document it. To search by id simply pass the id to the find method: Application.find(‘4c19e8facfbfb01794000002’) Rails And CoffeeScript I am a big fan of CoffeeScript so integrating it into this application is high on my priorities. My first thought was to copy Dr Nic’s strategy. Unfortunately, I did not get past step 1. Install Node.js. I am doing my development on Windows and node is unix only. I looked around for a solution but eventually had to concede defeat… for now. Quicksearch The front page of the application I am building displays a list of applications. When the user types in the search box I want to reduce the list of applications to match their search. A quick googlebing turned up quicksearch, a jquery plugin. You simply tell quicksearch where to get its input (the search textbox) and the list of items to filter (the divs containing the names of applications) and it just works. Here is the code: $('#app_search').quicksearch('.search_result'); Summary I have had a productive evening. The app now displays a list of applications, allows them to be sorted and links through to an application page when an application is selected. Next on the list is to display the set of keyboard shortcuts for an application.

• Apprentice Boot Camp in South Africa (Part 2)

  - by Tim Koekkoek

  By Maximilian Michel (DE), Jorge Garnacho (ES), Daniel Maull (UK), Adam Griffiths (UK), Guillermo De Las Nieves (ES), Catriona McGill (UK), Ed Dunlop (UK) Today we have the second part of the adventures of seven apprentices from all over Europe in South-Africa!  Kruger National Park & other experiences Going to the Kruger National Park was definitely an experience we will all remember for the rest of our lives. This trip,organised by Patrick Fitzgerald, owner of the Travellers Nest (where we all stayed), took us from the hustle and bustle of Joburg to experience what Africa is all about, the wild! Although the first week’s training we had prior to this trip to the Kruger was going very well, we all knew this was to be a very nice break before we started the second week of training. And we were right, the animals, scenery and sights we saw were just simply incredible and like I said something we will remember for the rest of our lives. To see lions, elephants, cheetahs and rhinos and many more in a zoo is one thing, but to see them in the wild, in their natural habitat is very special and I personally only realised this from the early 5 am start on the first morning in the Kruger, which was definitely worth it. Not only was it all about the safari, we ate some wonderful food, in particular on the Saturday night, Patrick made us a traditional South African Braai which was one of my favourite meals of the whole two weeks. After the Kruger National Park we had a whole day of traveling back to Johannesburg but even this was made to be a good day by our hosts. Despite the early start on the road it was all worth it by the time we reached God's Window. The walk to the top was made a lot harder by all the steaks we had eaten in the first week but the hard walk was worth it at the top, with views that stretched for miles. The Food The food in South Africa is typically meat and in big amounts, while there we ate a lot of big beef steaks, ribs and kudu sausage. All of the meat we ate was usually cooked with a sauce such as a Barbeque glaze. The restaurants we visited were: Upperdeck Restaurant, with live music and a great terrace to eat, the atmosphere was good for enjoying the music and eating our food. Most of us ate  Spare ribs that weighed 600 kg, with barbecue sauce that was delicious. Die Bosvelder Pub & Restaurant is a restaurant with a very surprising decor, this is because the walls had many of south Africa’s famous animals on them. The food was maybe the best we ate in South Africa. Our orders were: Springbokvlakte Lambs' Neck Stew, beef in gravy and steaks topped with cheese and then more meat on top! All meals were accompanied by a selection of white sauce cauliflower, spinach and zanhorias. Pepper Chair Restaurant, where the specialty is T-Bone steaks of 1.4 kg, but most of us were happy to attempt the 1 kg. Cooked with barbecue sauce over the meat, it was very good!  The only problem was their size causing the  the meat to get cold if you did not eat it very fast! We’re all waiting for our 1.0 kg t-bone steak including our Senior Director EMEA Systems Support Germany & Switzerland: Werner Hoellrigl The Godfather Restaurant, the food here was more meat in abundance. We ate: great ribs, hamburgers, steaks and all accompanied with a small plates of carrot and sauteed spinach, very good. We had two great weeks in South-Africa!

• Valuing "Working Software over Comprehensive Documentation"

As Oracle's chief methodologist, that might seem a self-deprecating attitude. After all, the agile manifesto tells us that we should value "individuals and interactions" over "processes and tools." My job includes process development. I also subscribe to ideas put forth in a number of subsequent works including Balancing Agility and Discipline: A Guide for the Perplexed (Boehm/Turner, Addison-Wesley) and Agile Project Management: Creating Innovative Products (Highsmith, Addison-Wesley). Both of these books talk about finding the right balance between "agility and discipline" or between a "predictive and adaptive" project approach. So there still seems to be a place for us in creating the Oracle Unified Method (OUM) to become the "single method framework that supports the successful implementation of every Oracle product." After all, the real idea is to apply just enough ceremony and produce just enough documentation to suit the needs of the particular project that supports an enterprise in moving toward its desired future state. The thing I've been struggling with - and the thing I'd like to hear from you about right now - is the prevalence of an ongoing obsession with "documents." OUM provides a comprehensive set of guidance for an iterative and incremental approach to engineering and implementing software systems. Our intent is first to support the information technology system implementation and, as necessary, support the creation of documentation. OUM, therefore, includes a supporting set of document templates. Our guidance is to employ those templates, sparingly, as needed; not create piles of documentation that you're not gonna (sic) need. In other words, don't serve the method, make the method serve you. Yet, there seems to be a "gimme" mentality in some circles that if you give me a sample document - or better yet - a repository of samples - then I will be able to do anything cheaply and quickly. The notion is certainly appealing AND reuse can save time. Plus, documents are a lowest common denominator way of packaging reusable stuff. However, without sustained investment and management I've seen "reuse repositories" turn quickly into garbage heaps. So, I remain a skeptic. I agree that providing document examples that promote consistency is helpful. However, there may be too much emphasis on the documents themselves and not enough on creating a system that meets the evolving needs of the business. How can we shift the emphasis toward working software and away from our dependency on documents - especially on large, complex implementation projects - while still supporting the need for documentation? I'd like to hear your thoughts.

• Impressions of Pivotal Tracker

  Pivotal Tracker is a free, online agile project management system. Ive been using it recently to better communicate to customers about the current state of our project. In Pivotal Tracker, the unit of work is a story and stories are arranged into iterations or delivery cycles. Stories can be any level of granularity you want, but the idea is to use stories to communicate clearly to customers, so you dont want to write a novel. You especially dont want to write a list of detailed programming tasks. A good story for a point of sale system might be: Allow managers to override the price of an item while ringing up a customer. A less useful story: Script out the process of adding a manager flag to the user table and stage that script into the deploy directory. Stories are estimated using a point scale, by default 1, 2 or 3. Iterations are then automatically laid out by combining enough tasks to fill the point total for that period of time. You have to start with a guess on how many points your team can do in an iteration, then adjust with real data as you complete iterations. This is basic agile methodology, but where Pivotal Tracker adds value is that it automatically and graphically lays out iterations for you on your project site. This makes communication and planning easy. Compiling release notes is no longer painful as it has been clear from the outset what work is going on. While I much prefer Pivotal Trackers customer facing interface over what we used previously (TFS), I see a couple of gaps. First, I have not able to make much headway with the reporting tools. Despite my complaints about TFS, it can produce some nice reports. Second, its not clear where if at all, Id keep track of purely internal tasks. Im talking about server maintenance, cleaning up source control, checking back on some code which you never quite felt right about. Theres no purpose in cluttering up an iteration backlog with these items, but if you dont track them, you lose them. Im not sure what a good answer for that is. One gap I thought Id see, which I dont, is more granular dev tasks. If Im implementing a story, Ill write out the steps and track my progress, but really, those steps arent useful to anybody but me. The only time Ive found that level of detail really useful is when my tasks are defined at too high a level anyway or when Im working with someone who needs more coaching and might not be able to finish a story in time without some scaffolding to get them going.

• At the Java DEMOgrounds - Oracle Java ME Embedded Enables the “Internet of Things”

  - by Janice J. Heiss

  I caught up with Oracle’s Robert Barnes, Senior Director, Java Product Management, who was demonstrating a new product from Oracle’s Java Platform, Micro Edition (Java ME) product portfolio, Oracle Java ME Embedded 3.2, a complete client Java runtime optimized for microcontrollers and other resource-constrained devices. Oracle’s Java ME Embedded 3.2 is a Java ME runtime based on CLDC 1.1 (JSR-139) and IMP-NG (JSR-228).“What we are showing here is the Java ME Embedded 3.2 that we announced last week,” explained Barnes. “It’s the start of the 'Internet of Things,’ in which you have very very small devices that are on the edge of the network where the sensors sit. You often have a middle area called a gateway or a concentrator which is fairly middle to higher performance. On the back end you have a very high performance server. What this is showing is Java spanning all the way from the server side right down towards the type of chip that you will get at the sensor side as the network.” Barnes explained that he had two different demos running.The first, called the Solar Panel System Demo, measures the brightness of the light.  “This,” said Barnes, “is a light source demo with a Cortex M3 controlling the motor, on the end of which is a sensor which is measuring the brightness of the lamp. This is recording the data of the brightness of the lamp and as we move the lamp out of the way, we should be able using the server to turn the sensor towards the lamp so the brightness reading will go higher. This sends the message back to the server and we can look at the web server sitting on the PC underneath the desk. We can actually see the data being passed back effectively through a back office type of function within a utility environment.” The second demo, the Smart Grid Response Demo, Barnes explained, “has the same board and processor and is still using Java ME embedded with a different app on top. This is a demand response demo. What we are seeing within the managing environment is that people want to track the pricing signals of the electricity. If it’s particularly expensive at any point in time, they may turn something off. This demo sets the price of the electricity as though this is coming from the back of the server sending pricing signals to my home.” The demo had a lamp and a fan and it was tracking the price of electricity. “If I set the price of the electricity to go over 5 cents, then the device will turn off,” explained Barnes. “I can go into my settings and, in this case, change the price to 50 cents and we can wait a minus and the lamp will go off. When I change the pricing signal so that it is lower, the lamp will come back on. The key point is that the Java software we have running is the same across all the different devices; it’s a way to build applications across multiple devices using the same software. This is important because it fixes peak loading on the network and can stops blackouts.” This demo brought me back to a prior decade when Sun Microsystems first promoted  Jini technology, a version of Java that would put everything on the network and give us the smart home. Your home would be automated to tell you when you were out of milk, when to change your light bulbs, etc. You would have access to the web and the network throughout your home.It’s interesting to see how technology moves over time – from the smart home to the Internet of Things.

  With OpenWorld over October was time to get back to serious work for everyone, including the Fusion Applications Developer Relations team. Don't forget the OpenWorld content is still available, including presentation downloads, for a limited period of time so be sure to grab anything you found useful or take another scan for anything you might have missed. Of all the announcements, the continued evolution of the Oracle Cloud services for extending and integrating with Fusion Applications is increasing in popularity, and certainly the Cloud Marketplace is something we're becoming involved in. More details to follow. Fusion Concepts Last week Vik from our team started the new "Fusion Concepts" series of articles, providing those new to Fusion Applications an explanation of the architectural basics, with the aim to reduce the learning curve and lay the platform for more efficient and effective development. The series begun with an insightful first post on the different schemas that exist in the Fusion Applications database. Look out for upcoming posts on multi-lingual entities, profile options, look-ups and more. New Learning Resources Our YouTube channel continued to expand with more 'how to' videos on using page composer, extending the Simplified UI (aka FUSE), and integrating BI reports and analytics. Also the Oracle Learning Library is now well established as a central resource for knowledge, now with thousands of tutorials, videos, and documents. Of particular note are the great new extensibility-related videos added by the CRM Product Management team, including more on the ever-expanding capabilities of Application Composer. To see some examples of these search using keyword 'customization' or the product 'Sales Cloud'. Finally on learning resources, as Oliver mentioned the Oracle Press book on Fusion Application Customization and Extensibility is now available for pre-order on Amazon (due out 1st Jan). Out And About October also saw us attend the annual Apps Conference held by the UK Oracle User Group in London. Interestingly there was an Applications Transformation stream of sessions and content that included Fusion Applications with all the latest in the Oracle Applications evolution, as always focused around the three tenets of social, mobile, and cloud. Read more in Richard's post-event write up. Other teams around Oracle have also been busy. Angelo from the Platform Technical Services group has done quite a bit of work using web services with Fusion SaaS and has published many interesting findings on his blog. It's definitely recommended reading if you are working on any related integration projects. The middleware-for-applications group has built a new tool called "AppAdvantage" offering an online assessment of your use of Fusion Middleware technologies with Oracle Applications. As the popularity of integrating cloud applications with on-premises systems continued to grow, leveraging existing middleware technologies (and licenses) to support the integration solution is likely to be of paramount importance. Similarly the "Build Enterprise Application Extensions with Ease" section of the related webpage has AppsUX director Killan Evers speaking about customization using the composer tools. Both are useful resources for those just getting started with a move to Fusion Applications. The Oracle A-Team, specialists in middleware technical architecture, always publish superb content via their 'chronicles' site, now with a substantial amount specifically related to Fusion Applications. Click on the Fusion Applications menu on the top right of their homepage to see more. Last month of particular note was an article on customizing the timeout pop-up message that shows to inactive users, providing design-time insight and easy-to-follow steps. Finally if you're looking at using Oracle Middleware and Cloud to tailor and extend your applications then you may also be interested in this new blog post on the roadmap for Oracle SOA and the latest on-demand Cloud Development webcast.

• Dell 3721 Wifi problem Ubuntu 13.04

  - by Sebastian

  I have a Dell 3721 which comes original with windows 8. I managed it to install ubuntu 12.10 on this laptop, even there was no out of the box drivers. With 12.10 I was forces to install this .deb package couple of times. After installing it, it was ok for some weeks before I have to install it again. Maybe some security updates destroy something which made in necessary to install it again... http://jas.gemnetworks.com/debian/pool/main/w/wireless-bcm43142/wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb My problem is, that this package isnt working with ubuntu 13.04 anymore. So I cant use Wifi now. Also my display is almost dark, I cant change the brightness level with ubuntu 13.04. Hope you can give me some advice.

• Good DBAs Do Baselines

  - by Louis Davidson

  One morning, you wake up and feel funny. You can’t quite put your finger on it, but something isn’t quite right. What now? Unless you happen to be a hypochondriac, you likely drag yourself out of bed, get on with the day and gather more “evidence”. You check your symptoms over the next few days; do you feel the same, better, worse? If better, then great, it was some temporal issue, perhaps caused by an allergic reaction to some suspiciously spicy chicken. If the same or worse then you go to the doctor for some health advice, but armed with some data to share, and having ruled out certain possible causes that are fixed with a bit of rest and perhaps an antacid. Whether you realize it or not, in comparing how you feel one day to the next, you have taken baseline measurements. In much the same way, a DBA uses baselines to gauge the gauge health of their database servers. Of course, while SQL Server is very willing to share data regarding its health and activities, it has almost no idea of the difference between good and bad. Over time, experienced DBAs develop “mental” baselines with which they can gauge the health of their servers almost as easily as their own body. They accumulate knowledge of the daily, natural state of each part of their database system, and so know instinctively when one of their databases “feels funny”. Equally, they know when an “issue” is just a passing tremor. They see their SQL Server with all of its four CPU cores running close 100% and don’t panic anymore. Why? It’s 5PM and every day the same thing occurs when the end-of-day reports, which are very CPU intensive, are running. Equally, they know when they need to respond in earnest when it is the first time they have heard about an issue, even if it has been happening every day. Nevertheless, no DBA can retain mental baselines for every characteristic of their systems, so we need to collect physical baselines too. In my experience, surprisingly few DBAs do this very well. Part of the problem is that SQL Server provides a lot of instrumentation. If you look, you will find an almost overwhelming amount of data regarding user activity on your SQL Server instances, and use and abuse of the available CPU, I/O and memory. It seems like a huge task even to work out which data you need to collect, let alone start collecting it on a regular basis, managing its storage over time, and performing detailed comparative analysis. However, without baselines, though, it is very difficult to pinpoint what ails a server, just by looking at a single snapshot of the data, or to spot retrospectively what caused the problem by examining aggregated data for the server, collected over many months. It isn’t as hard as you think to get started. You’ve probably already established some troubleshooting queries of the type SELECT Value FROM SomeSystemTableOrView. Capturing a set of baseline values for such a query can be as easy as changing it as follows: INSERT into BaseLine.SomeSystemTable (value, captureTime) SELECT Value, SYSDATETIME() FROM SomeSystemTableOrView; Of course, there are monitoring tools that will collect and manage this baseline data for you, automatically, and allow you to perform comparison of metrics over different periods. However, to get yourself started and to prove to yourself (or perhaps the person who writes the checks for tools) the value of baselines, stick something similar to the above query into an agent job, running every hour or so, and you are on your way with no excuses! Then, the next time you investigate a slow server, and see x open transactions, y users logged in, and z rows added per hour in the Orders table, compare to your baselines and see immediately what, if anything, has changed!

• A story of Murphy&ndash;my technical issues at TechDays Switzerland #chtd

  - by Laurent Bugnion

  I had two sessions at the recent Swiss TechDays. While the first one (Advanced Development for Windows Phone 8) went extremely well (I think), I had a very annoying technical issue in the beginning of my second session. First let me add that I talked to Microsoft about that and I hope they will change a few things in the room assignment for next year. My two sessions were one right after the other, with only 15 minutes break to change room. I don’t mind having two sessions so close from each other, but I would really like them to be in the same room in order to avoid having to move my laptops (plural, that will become important later) and redoing the tech check. That being said, I am guilty of not checking where my talks would be before the day before the conference, and when I did notice, it was too late to change it. After my first session, I quickly moved to the other room and setup my main laptop, a Dell Precision. We tested the video output (VGA) and didn’t notice anything special. The projectors are using a fairly high resolution (kudos to the Basel conference center for not having old school 1024x768 projectors anymore, that makes Blend really hard to demo ;) but since everything went great during the first talk, I was not worried. In fact I even had some time to chat with some early attendees about my Microsoft Surface and the Samsung Slate 7, which I had carried with me in addition to the Precision. I just thought it would be nice to show the hardware that Windows 8 can run on, without thinking any further. When the session started, I immediately noticed that the main screen was not showing anything. I thought I had just forgotten to switch to “duplicate” for the video output, and did that with a quick Win-P. However it didn’t “hold”. After 2 seconds, it reverted back to a black display for my attendees. Then I started to really worry. We tried everything, switching from VGA to HDMI, changing the resolution, setting the projector as primary display, but nothing did the trick. The projector was just refusing to show my screen. Now, to show you how despaired I started to be, I even considered using the “extend” setting (which worked just fine), and to use one of the feedback monitors on the floor but really it was super cumbersome. Eventually, my last resort arrived: I started my Samsung Slate 7, which by chance has Visual Studio 12 and Blend 5 installed, plugged the HDMI projector in the dock (yes, I had the dock with me, which I usually don’t!), connected it to internet (had to enter a long password for that), loaded the source code from my main machine using a USB stick and…. finally started to give my presentation. All in all I think we lost about 10 minutes. Amongst the most horrible minutes of my whole life, truly (yes I am blessed, I didn’t have that many horrible minutes in my life ;) I really want to apologize to my attendees. We joked a bit during the attempts to resolve the issue, the reactions I had after the session were all very nice and sympathetic. Only a handful of people left my session while I was having the issues, and I really don’t blame them (who knew how long the problem would last!!). But still, I probably talked at more than 60 sessions over the years, and this was by far my most painful moment. What did I learn? So what did I learn from this? Well from now on I will always have my slate ready with the latest source code, internet connection and every tool I might need during the presentation. This way, if I detect even a hint that the Precision might not work, I will just switch to the Slate. The experience of presenting on the slate is actually not bad at all, it is just a bit slow for my taste, but it does work. By the way, I will be posting the code and slides for my sessions very soon, I just need to “clean it and zip it”. Stay tuned, and thanks again for your patience in that horrible circumstance.

• SQL Authority News – FalafelCON 2014: 2 days with the Best Developers in the World

  - by Pinal Dave

  I love presenting at various forums on various technologies. I am extremely excited that I got invited to speak at Falafel Conference 2014 in San Francisco. I will present two technology sessions on SQL Server. If you are into web development or if you just want to attend a conference with the best of the industry speakers, this may be the right conference for you. What set apart this conference from other conference is technology presented as well as speakers. Usually one has to attend very expensive and high scale event when they have to hear good speakers. At this conference, you will find quite a many industry legends are available to present on the bleeding edge technology. Here are few of the reasons why I believe you should attend this conference: Choose from four tracks covering Web, Mobile development and testing, Sitefinity, and Automated Testing, or attend sessions from all four! Learn from the best developers and testers in the business in an intimate setting. Surround yourself with your peers and the opportunity to network Learn about the latest platforms and technologies including Kendo UI, AngularJS, ASP.NET MVC, WebAPI, and more! Here are the details for the sessions which I am going to present at Falafel Conference. Secrets of SQL Server: Database Worst Practices Abstract: Chances are you have heard, or even uttered, this expression. This demo-oriented session will show many examples where database professionals were dumbfounded by their own mistakes, and could even bring back memories of your own early DBA days. The goal of this session is to expose the small details that can be dangerous to the production environment and SQL Server as a whole, as well as talk about worst practices and how to avoid them. Shedding light on some of these perils and the tricks to avoid them may even save your current job. After attending this session, Developers will only need 60 seconds to improve performance of their database server in their SharePoint implementation. We will have a quiz during the session to keep the conversation alive. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Additionally, all attendees of the session will have access to learning material presented in the session. The Unsung Hero Abstract: Slow Running Queries are the most common problem that developers face while working with SQL Server. While it is easy to blame the SQL Server for unsatisfactory performance, however the issue often persists with the way queries have been written, and how Indexes has been set up. The session will focus on the ways of identifying problems that slow down SQL Server, and Indexing tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Register Now! I have learned from the Falafel Team that they are running out of tickets and soon they will close the registration.  For next 10 days the price for the registration is only USD 149. Trust me, you can’t get such a world class training and networking opportunity at such a low price. Click to Register Here!

• The Healthy Tension That Mobility Creates

  - by Kathryn Perry

  A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps In my previous post, I talked about the value of the mobile revolution on businesses and workers. Now let me put on a different hat and view the world from the IT department and the IT leader’s viewpoint. The IT leader has different concerns – around privacy, potential liability of information leakage, and intellectual property protection. These concerns and the leader’s goals create a healthy tension with the users. For example, effective device management becomes a must have for the IT leader, especially if you look at the Android ecosystem as an example. There are benefits to the Android strategy, but there are also drawbacks, such as uniformity – in device management, in operating systems, and in the application taxonomy and capabilities. Whereas, if you compare Android to iOS, Apple's operating system, iOS is more unified, more streamlined, and easier to manage. In either case, this is where mobile device management in the cloud makes good sense. I don't think IT departments should be hosting device management and managing that complexity. It should be a cloud service and I predict it's going to be key for our customers. A New Focus for IT Departments So where does that leave the IT departments? I think their futures are in governance, which is a more strategic play than a tactical one. Device management is tactical and it's the “now” topic. But the mobile phenomenon, if you will, is going to drive significant change in terms of how IT plans, hosts, and deploys enterprise applications. For example, opening up enterprise applications for mobile users presents some challenges unless you deploy more complicated network topologies, such as virtual private networks and threat protection technology. If you really want employees to be mobile you need to remove those kinds of barriers. But I don’t think IT departments want to wrestle with exposing their private enterprise data centers and being responsible for hosted business applications – applications in a sense that they’re making vulnerable to the public world. This opens up a significant need and a significant driver for cloud applications. However, it's not just about taking away the complexity – it's also about taking away the responsibility. Why should every business have to carry the responsibility and figure out all the nuts and bolts of how to protect themselves in this public, mobile world? When you use apps in the cloud, either your vendor or your hosting partner should have figured all that out. They need to assure the business that they are adhering to all sorts of security and compliance regulations so users can be connected and have access to information anywhere anytime. More Ideas and Better Service What’s more interesting is the world of possibilities that the connected, cloud-based world enables. I believe that the one-size-fits-all, uber-best practices, lowest-common denominator-like capabilities will go away. IT will now be able to solve very specific business challenges for the different corporate functions it serves. In this new world, IT will play a key role in enabling different organizations within a company to be best in class and delivering greater value to the line of business managers. IT will actually help to differentiate. Net result is a more agile workforce and business because each department is getting work done its own way.

• Ubuntu keyboard shortcuts - two-part question

  - by Don

  Background: I come from a Windows background and just started dual-booting Ubuntu (my first Linux experience) about 4 days ago. So my systems are Windows 7/Ubuntu 12.04, and so far I'm loving Ubuntu. I am a dedicated mouse-abolitionist (trackpads are hell) and do most of my browsing and navigation with keyboard shortcuts. However, on switching to Ubuntu, a lot of my keyboard shortcuts are gone, and my productivity has resultantly taken a huge hit anytime I am using Ubuntu. Problem 1: My computer was designed to display on-screen notifications for a second when I hit caps-lock or num-lock, and there are no constant indicators of the lock status (LEDs, etc). In Ubuntu, the keys still worked, but the notifications were gone. Googling got me a tutorial on key-binding(Compiz) and scripts, so now I have capslock and numlock running this script: #!/bin/bash icon="/usr/share/icons/gnome/scalable/devices/keyboard.svg" case $1 in 'scrl') mask=3 key="Scroll" ;; 'num') mask=2 key="Num" ;; 'caps') mask=1 key="Caps" ;; esac value=$(xset q | grep "LED mask" | sed -r "s/.*LED mask:\s+[0-9a-fA-F]+([0-9a-fA-F]).*/\1/") if [ $(( 0x$value & 0x$mask )) == $mask ] then output="$key Lock" output2="On" else output="$key Lock" output2="Off" fi notify-send -i $icon "$output" "$output2" -t 1000 But, whether turning it off or on, the notifications always say that I have turned it on. Is there an easy fix for this, or an easier way to work it to get it do display the CORRECT notifications? Problem 2: I'm not sure if this is because of my keyboard or Ubuntu. In Windows, I use Chrome and use the ctrl+pgUp/pgDwn shortcuts quite a bit to switch between tabs. On my keyboard, I can enter pgUp and pgDwn by either disabling NumLock and hitting 9 or 3 respectively on the 10key. Alternately I can hold the fn key and hit up or down arrow. The first method is the one I very heavily relied upon, and it works in Firefox for Ubuntu, but not in Chrome nor in Chromium. The second method (ctrl + fn + up/down) works fine in Chrome. However, I'd dearly like to find a method to make the first method work. Any suggestions? Thanks in advance for your help. Update: @julien: I've checked the keyboard layout options - I didn't find anything that seemed useful for this goal. @Marty: The script runs once when the button is pressed. In Compiz, I've tied those two keys to the script, so when I press the button, it runs the script with the button pressed as a parameter. Update: @elmicha: Thanks. That one works a lot better, and it even pops an icon into the status bar when caps lock is on. There's still a very slight problem in that if I quickly tap the key twice, the image will show that it has been turned on and then turned off, and the notifaction will come and go from my status area, but the text of both notifications will be "Caps Lock on". Same with Num Lock. However, if the time between presses is long enough for the first notification to disappear, everything displays correctly. Given how quickly the notifications disappear, I don't expect this will pose too much of a problem for me.

• Errors when trying to compile the driver for the rtl8192su wireless adapter

  I have a wireless to usb adapter, and I'm having some trouble to install the drivers on Ubuntu. First of all, the readme says to use the make command, and I already got errors: $ make make[1]: Entering directory `/usr/src/linux-headers-2.6.35-22-generic' CC [M] /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’: /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12325: error: ‘struct net_device’ has no member named ‘open’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12326: error: ‘struct net_device’ has no member named ‘stop’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12327: error: ‘struct net_device’ has no member named ‘tx_timeout’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12328: error: ‘struct net_device’ has no member named ‘do_ioctl’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12329: error: ‘struct net_device’ has no member named ‘set_multicast_list’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12330: error: ‘struct net_device’ has no member named ‘set_mac_address’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12331: error: ‘struct net_device’ has no member named ‘get_stats’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12332: error: ‘struct net_device’ has no member named ‘hard_start_xmit’ make[2]: *** [/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o] Error 1 make[1]: *** [_module_/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic' make: *** [all] Error 2 /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/ is the path where I copied the drivers on my computer.

• Why do I need two Instances in Windows Azure?

  - by BuckWoody

  Windows Azure as a Platform as a Service (PaaS) means that there are various components you can use in it to solve a problem: Compute “Roles” - Computers running an OS and optionally IIS - you can have more than one "Instance" of a given Role Storage - Blobs, Tables and Queues for Storage Other Services - Things like the Service Bus, Azure Connection Services, SQL Azure and Caching It’s important to understand that some of these services are Stateless and others maintain State. Stateless means (at least in this case) that a system might disappear from one physical location and appear elsewhere. You can think of this as a cashier at the front of a store. If you’re in line, a cashier might take his break, and another person might replace him. As long as the order proceeds, you as the customer aren’t really affected except for the few seconds it takes to change them out. The cashier function in this example is stateless. The Compute Role Instances in Windows Azure are Stateless. To upgrade hardware, because of a fault or many other reasons, a Compute Role's Instance might stop on one physical server, and another will pick it up. This is done through the controlling fabric that Windows Azure uses to manage the systems. It’s important to note that storage in Azure does maintain State. Your data will not simply disappear - it is maintained - in fact, it’s maintained three times in a single datacenter and all those copies are replicated to another for safety. Going back to our example, storage is similar to the cash register itself. Even though a cashier leaves, the record of your payment is maintained. So if a Compute Role Instance can disappear and re-appear, the things running on that first Instance would stop working. If you wrote your code in a Stateless way, then another Role Instance simply re-starts that transaction and keeps working, just like the other cashier in the example. But if you only have one Instance of a Role, then when the Role Instance is re-started, or when you need to upgrade your own code, you can face downtime, since there’s only one. That means you should deploy at least two of each Role Instance not only for scale to handle load, but so that the first “cashier” has someone to replace them when they disappear. It’s not just a good idea - to gain the Service Level Agreement (SLA) for our uptime in Azure it’s a requirement. We point this out right in the Management Portal when you deploy the application: (Click to enlarge) When you deploy a Role Instance you can also set the “Upgrade Domain”. Placing Roles on separate Upgrade Domains means that you have a continuous service whenever you upgrade (more on upgrades in another post) - the process looks like this for two Roles. This example covers the scenario for upgrade, so you have four roles total - One Web and one Worker running the "older" code, and one of each running the new code. In all those Roles you want at least two instances, and this example shows that you're covered for High Availability and upgrade paths: The take-away is this - always plan for forward-facing Roles to have at least two copies. For Worker Roles that do background processing, there are ways to architect around this number, but it does affect the SLA if you have only one.

• PowerShell: Read Excel to Create Inserts

  - by BuckWoody

  I’m writing a series of articles on how to migrate “departmental” data into SQL Server. I also hold workshops on the entire process – from discovering that the data exists to the modeling process and then how to design the Extract, Transform and Load (ETL) process. Finally I write about (and teach) a few methods on actually moving the data. One of those options is to use PowerShell. There are a lot of ways even with that choice, but the one I show is to read two columns from the spreadsheet and output statements that would insert the data using a stored procedure. Of course, you could re-write this as INSERT statements, out to a text file for bcp, or even use a database connection in the script to move the data directly from Excel into SQL Server. This snippet won’t run on your system, of course – it assumes a Microsoft Office Excel 2007 spreadsheet located at c:\temp called VendorList.xlsx. It looks for a tab in that spreadsheet called Vendors. The statement that does the writing just uses one column: Vendor Code. Here’s the breakdown of what I’m doing: In the first block, I connect to Microsoft Office Excel. That connection string is specific to Excel 2007, so if you need a different version you’ll need to look that up. In the second block I set up a selection from the entire spreadsheet based on that tab. Note that if you’re only after certain data you shouldn’t get the whole spreadsheet – that’s just good practice. In the next block I create the text I want, inserting the Vendor Code field as I go. Finally I close the connection. Enjoy! $ExcelConnection= New-Object -com "ADODB.Connection" $ExcelFile="c:\temp\VendorList.xlsx" $ExcelConnection.Open("Provider=Microsoft.ACE.OLEDB.12.0;` Data Source=$ExcelFile;Extended Properties=Excel 12.0;") $strQuery="Select * from [Vendors$]" $ExcelRecordSet=$ExcelConnection.Execute($strQuery) do { Write-Host "EXEC sp_InsertVendors '" $ExcelRecordSet.Fields.Item("Vendor Code").Value "'" $ExcelRecordSet.MoveNext()} Until ($ExcelRecordSet.EOF) $ExcelConnection.Close() Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary.

• Learn Many Languages

  - by Phil Factor

  Around twenty-five years ago, I was trying to solve the problem of recruiting suitable developers for a large business. I visited the local University (it was a Technical College then). My mission was to remind them that we were a large, local employer of technical people and to suggest that, as they were in the business of educating young people for a career in IT, we should work together. I anticipated a harmonious chat where we could suggest to them the idea of mentioning our name to some of their graduates. It didn’t go well. The academic staff displayed a degree of revulsion towards the whole topic of IT in the world of commerce that surprised me; tweed met charcoal-grey, trainers met black shoes. However, their antipathy to commerce was something we could have worked around, since few of their graduates were destined for a career as university lecturers. They asked me what sort of language skills we needed. I tried ducking the invidious task of naming computer languages, since I wanted recruits who were quick to adapt and learn, with a broad understanding of IT, including development methodologies, technologies, and data. However, they pressed the point and I ended up saying that we needed good working knowledge of C and BASIC, though FORTRAN and COBOL were, at the time, still useful. There was a ghastly silence. It was as if I’d recommended the beliefs and practices of the Bogomils of Bulgaria to a gathering of Cardinals. They stared at me severely, like owls, until the head of department broke the silence, informing me in clipped tones that they taught only Modula 2. Now, I wouldn’t blame you if at this point you hurriedly had to look up ‘Modula 2′ on Wikipedia. Based largely on Pascal, it was a specialist language for embedded systems, but I’ve never ever come across it in a commercial business application. Nevertheless, it was an excellent teaching language since it taught modules, scope control, multiprogramming and the advantages of encapsulating a set of related subprograms and data structures. As long as the course also taught how to transfer these skills to other, more useful languages, it was not necessarily a problem. I said as much, but they gleefully retorted that the biggest local employer, a defense contractor specializing in Radar and military technology, used nothing but Modula 2. “Why teach any other programming language when they will be using Modula 2 for all their working lives?” said a complacent lecturer. On hearing this, I made my excuses and left. There could be no meeting of minds. They were providing training in a specific computer language, not an education in IT. Twenty years later, I once more worked nearby and regularly passed the long-deserted ‘brownfield’ site of the erstwhile largest local employer; the end of the cold war had led to lean times for defense contractors. A digger was about to clear the rubble of the long demolished factory along with the accompanying growth of buddleia and thistles, in order to lay the infrastructure for ‘affordable housing’. Modula 2 was a distant memory. Either those employees had short working lives or they’d retrained in other languages. The University, by contrast, was thriving, but I wondered if their erstwhile graduates had ever cursed the narrow specialization of their training in IT, as they struggled with the unexpected variety of their subsequent careers.

• The Raspberry Pi JavaFX In-Car System (Part 3)

  - by speakjava

  Ras Pi car pt3 Having established communication between a laptop and the ELM327 it's now time to bring in the Raspberry Pi. One of the nice things about the Raspberry Pi is the simplicity of it's power supply.  All we need is 5V at about 700mA, which in a car is as simple as using a USB cigarette lighter adapter (which is handily rated at 1A).  My car has two cigarette lighter sockets (despite being specified with the non-smoking package and therefore no actual cigarette lighter): one in the centre console and one in the rear load area.  This was convenient as my idea is to mount the Raspberry Pi in the back to minimise the disruption to the very clean design of the Audi interior. The first task was to get the Raspberry Pi to communicate using Wi-Fi with the ELM 327.  Initially I tried a cheap Wi-Fi dongle from Amazon, but I could not get this working with my home Wi-Fi network since it just would not handle the WPA security no matter what I did.  I upgraded to a Wi Pi from Farnell and this works very well. The ELM327 uses Ad-Hoc networking, which is point to point communication.  Rather than using a wireless router each connecting device has its own assigned IP address (which needs to be on the same subnet) and uses the same ESSID.  The settings of the ELM327 are fixed to an IP address of 192.168.0.10 and useing the ESSID, "Wifi327".  To configure Raspbian Linux to use these settings we need to modify the /etc/network/interfaces file.  After some searching of the web and a few false starts here's the settings I came up with: auto lo eth0 wlan0 iface lo inet loopback iface eth0 inet static     address 10.0.0.13     gateway 10.0.0.254     netmask 255.255.255.0 iface wlan0 inet static     address 192.168.0.1     netmask 255.255.255.0     wireless-essid Wifi327     wireless-mode ad-ho0 After rebooting, iwconfig wlan0 reported that the Wi-Fi settings were correct.  However, ifconfig showed no assigned IP address.  If I configured the IP address manually using ifconfig wlan0 192.168.0.1 netmask 255.255.255.0 then everything was fine and I was able to happily ping the IP address of the ELM327.  I tried numerous variations on the interfaces file, but nothing I did would get me an IP address on wlan0 when the machine booted.  Eventually I decided that this was a pointless thing to spend more time on and so I put a script in /etc/init.d and registered it with update-rc.d.  All the script does (currently) is execute the ifconfig line and now, having installed the telnet package I am able to telnet to the ELM327 via the Raspberry Pi.  Not nice, but it works. Here's a picture of the Raspberry Pi in the car for testing In the next part we'll look at running the Java code on the Raspberry Pi to collect data from the car systems.

• Walkthrough: Scheduling jobs using Quartz.net &ndash; Part 1: What is Quartz.Net?

  - by Tarun Arora

  Quartz.NET is a full-featured, open source enterprise job scheduling system written in .NET platform that can be used from smallest apps to large scale enterprise systems. What is the problem that we trying to address? I want to schedule the execution of a task but only when something happens. Let’s call that something a trigger, so... if the trigger is met => execute the task. Sounds simple, why not use windows task scheduler for this? Well, windows task scheduler is great for tasks where the trigger can be easily defined. With windows task scheduler will you be able to schedule a task to run on every working day according to the UK calendar (exclude all weekends & bank holidays) without either writing the logic for day check in the task or a wrapper script calling into the task. The task should just contain the execution logic and should not have anything to do with the schedule for execution; Quartz.net allows you to achieve this and lots more. A quartz.net trigger gives you the flexibility for task invocation based on the following triggers, 1. at a certain time of day (to the millisecond) 2. on certain days of the week 3. on certain days of the month 4. on certain days of the year 5. not on certain days listed within a registered Calendar (such as business holidays) 6. repeated a specific number of times 7. repeated until a specific time/date 8. repeated indefinitely 9. repeated with a delay interval Did 8 – repeat indefinitely just ring a bell? I’ll be covering that in the future post. Using Quartz.net as a windows service You can have Quartz.net run as a standalone instance within its own .NET virtual machine instance via .NET Remoting. Let’s take a look at typical application architecture. In the figure below, I have the application tier set up on Machine 1, database set up on Machine 2 and Quartz.net set up on Machine 3 which is normally the architecture for most (if not all) enterprise applications. Figure 1 -  Typical Application architecture while using Quartz.net as a windows service What other options do I have if I don’t want to use Quartz.net? Quartz.net is just one of the many job scheduling services. Have a look at this comprehensive list of free and paid enterprise job scheduling software along with their feature comparison. http://en.wikipedia.org/wiki/List_of_job_scheduler_software This was first in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering how to Install Quartz.net as a windows service.
