• Laptop monitor stopped working and can't be re-enabled on a Dell Latitude E6410

  - by xektrum

  I'm using Ubuntu 12.04 (upgraded from 11.10), everything seemed to work fine until today when my laptop monitor suddenly stopped working. Here are the facts: My laptop is a Dell Latitude E6410, Intel graphics. External Monitor is attached through a docking station. Everything worked fine for about 6-7 month, then upgraded to 12.04 Issue started today after a week of upgrade. I think the issue started after I ran CounterStrike 1.6, both monitors blinked and then only the attached monitor which is connected to a docking station continued to work I thought at first that was a transient issue but then I've rebooted, removed the battery but the same happens. Laptop Monitor and external monitor work fine up to login screen, but after I login it goes black Whenever I try to re-enable laptop monitor from Display Manager I get errors: The selected configuration for displays could not be applied could not set the configuration for CRTC 63 Not sure what technical details are required but here are some: $ xrandr Screen 0: minimum 320 x 200, current 3120 x 1050, maximum 8192 x 8192 eDP1 connected (normal left inverted right x axis y axis) 1440x900 60.0 + 40.0 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) $ tail /var/log/Xorg.0.log [ 8367.132] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.132] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.174] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.174] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.174] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.174] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.265] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.265] (WW) intel(0): Page flip failed: Device or resource busy [ 8367.265] (WW) intel(0): flip queue failed: Device or resource busy [ 8367.265] (WW) intel(0): Page flip failed: Device or resource busy I'm using gnome-shell, and the only ways I've been able to get both display working have been: 1) Booting with laptop disconnected from docking and then re attach external with VGA instead of DVI, but only worked for a session. 2) Removing xserver-xorg-video-intel, but then I gnome-shell is gone as well as dri I would appreciate any suggestions. Regards, ============================= WORKAROUND FOUND ============================= So I have tried few things and here is what worked: I've installed a newer version of xserver-xorg-video-intel (2.19 vs 2.17) from ppa:xorg-edgers/ppa, it didn't work at first, it was only showing low graphics mode, so I tried with a different linux-image 3.0.0-19-generic-pae instead of 3.2.0-24-generic-pae, which I believe is 12.04 precise default, then everything started to work again, Now I've installed 3.4.0-1-generic-pae from same ppa and everything goes flawless so I believe the issue is either with linux-image 3.0.0-19-generic-pae or xserver-xorg-video-intel 2.17. Hope this helps someone in the future.

• Normalisation and 'Anima notitia copia' (Soul of the Database)

  - by Phil Factor

  (A Guest Editorial for Simple-Talk) The other day, I was staring  at the sys.syslanguages  table in SQL Server with slightly-raised eyebrows . I’d just been reading Chris Date’s  interesting book ‘SQL and Relational Theory’. He’d made the point that you’re not necessarily doing relational database operations by using a SQL Database product.  The same general point was recently made by Dino Esposito about ASP.NET MVC.  The use of ASP.NET MVC doesn’t guarantee you a good application design: It merely makes it possible to test it. The way I’d describe the sentiment in both cases is ‘you can hit someone over the head with a frying-pan but you can’t call it cooking’. SQL enables you to create relational databases. However,  even if it smells bad, it is no crime to do hideously un-relational things with a SQL Database just so long as it’s necessary and you can tell the difference; not only that but also only if you’re aware of the risks and implications. Naturally, I’ve never knowingly created a database that Codd would have frowned at, but around the edges are interfaces and data feeds I’ve written  that have caused hissy fits amongst the Normalisation fundamentalists. Part of the problem for those who agonise about such things  is the misinterpretation of Atomicity.  An atomic value is one for which, in the strange virtual universe you are creating in your database, you don’t have any interest in any of its component parts.  If you aren’t interested in the electrons, neutrinos,  muons,  or  taus, then  an atom is ..er.. atomic. In the same way, if you are passed a JSON string or XML, and required to store it in a database, then all you need to do is to ask yourself, in your role as Anima notitia copia (Soul of the database) ‘have I any interest in the contents of this item of information?’.  If the answer is ‘No!’, or ‘nequequam! Then it is an atomic value, however complex it may be.  After all, you would never have the urge to store the pixels of images individually, under the misguided idea that these are the atomic values would you?  I would, of course,  ask the ‘Anima notitia copia’ rather than the application developers, since there may be more than one application, and the applications developers may be designing the application in the absence of full domain knowledge, (‘or by the seat of the pants’ as the technical term used to be). If, on the other hand, the answer is ‘sure, and we want to index the XML column’, then we may be in for some heavy XML-shredding sessions to get to store the ‘atomic’ values and ensure future harmony as the application develops. I went back to looking at the sys.syslanguages table. It has a months column with the months in a delimited list January,February,March,April,May,June,July,August,September,October,November,December This is an ordered list. Wicked? I seem to remember that this value, like shortmonths and days, is treated as a ‘thing’. It is merely passed off to an external  C++ routine in order to format a date in a particular language, and never accessed directly within the database. As far as the database is concerned, it is an atomic value.  There is more to normalisation than meets the eye.

• TechEd 2010 Day Three: The Database Designer (Isn't)

  - by BuckWoody

  Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

• Getting Started with StreamInsight 2.1

  - by Roman Schindlauer

  If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get me going? If that describes you, then this blog entry might be just what you need. If you're already a StreamInsight wiz, keep reading anyway - you may find some helpful links here that you weren't aware of. But here's what we'd like from you experienced readers in particular: if you know of other good resources that we missed, please feel free to add them in the comments below. We appreciate you sharing your expertise. The Book The basic documentation for StreamInsight is located in the MSDN Library (Microsoft StreamInsight 2.1). You'll notice that previous versions of StreamInsight are still there (1.2 and 2.0), but if you're just getting started you can stick to the 2.1 section. The documentation has been organized to function as reference material, which is fine after you're familiar with the technology. But if you're trying to learn the basics, you might want to take a different path instead of just starting at the top. The following is one map you can use. What Is StreamInsight? Here is a sequence of topics that should give you a good overview of what StreamInsight is and how it works: Overview answers the question, "what is it?" StreamInsight Server Architecture gives you a quick look at a high-level architectural drawing StreamInsight Concepts lays out an overview of the basic components Deploying StreamInsight Entities to a StreamInsight Server describes the mechanics of how these components work together Getting an Example Running Once you have this background, go ahead and install StreamInsight and get a basic example up and running: Installation download and install the software StreamInsight Examples walk through a set of 3 simple StreamInsight applications that work together to demonstrate what you learned in the topics above; you can copy and paste the code into Visual Studio, compile, and run That's it - you now have a real, functioning StreamInsight system! Now that you have a handle on the basics, you might want to start digging deeper. Digging Deeper Here's a suggested path through the documentation to help you understand the next layer of StreamInsight technologies: Using Event Sources and Event Sinks sources supply data and sinks consume it; this topic gives you an overview of how they work Publishing and Connecting to the StreamInsight Server practical details on how to set up a StreamInsight server A Hitchhiker’s Guide to StreamInsight 2.1 Queries queries are the heart of how StreamInsight performs data analytics, and this whitepaper will help you really understand how they work Using StreamInsight LINQ root through this section for technical details on specific query components Using the StreamInsight Event Flow Debugger in addition to troubleshooting, the debugger is a great way to learn more about what goes on inside a StreamInsight application And Even Deeper Finally, to get a handle on some of the more complex things you can do with StreamInsight, dig into these: Input and Output Adapters adapters can be useful for handling more complex sources and sinks Building Resilient StreamInsight Applications a resilient application is able to recover from system failures Operations this section will help you monitor and troubleshoot a running StreamInsight system The StreamInsight Community As you're designing and developing your StreamInsight solutions, you probably will find it helpful to see working examples or to learn tips and tricks from others. Or maybe you need a place to post a vexing question. Here are some community resources that we have found useful. If you know of others, please add them in the comments below. Code samples and tools Official StreamInsight code samples Introduction to LinqPad Driver for StreamInsight 2.1 - LinqPad is a very useful tool for developing queries The following case studies are based on earlier versions of StreamInsight, but they still are useful examples: Microsoft Media Analytics - real-time monitoring and analytic Edgenet - responding to information from multiple source ICONICS - managing energy usage Blogs Microsoft StreamInsight Ruminations of J.net Richard Seroter's Architecture Musings pluralsight Forums MSDN StreamInsight Forum stackoverflow Training Microsoft StreamInsight Fundamentals (“Introducing StreamInsight” is free) from pluralsight Twitter @streaminsight   You’re a StreamInsight Expert That should get you going.

• Compute directional light frustum from view furstum points and light direction

  - by Fabian

  I'm working on a friends engine project and my task is to construct a new frustum from the light direction that overlaps the view frustum and possible shadow casters. The project already has a function that creates a frustum for this but its way to big and includes way to many casters (shadows) which can't be seen in the view frustum. Now the only parameter of this function are the normalized light direction vector and a view class which lets me extract the 8 view frustum points in world space. I don't have any additional infos about the scene. I have read some of the related Questions here but non seem to fit very well to my problem as they often just point to cascaded shadow maps. Sadly i can't use DX or openGl functions directly because this engine has a dedicated math library. From what i've read so far the steps are: Transform view frustum points into light space and find min/max x and y values (or sometimes minima and maxima of all three axis) and create a AABB using the min/max vectors. But what comes after this step? How do i transform this new AABB back to world space? What i've done so far: CVector3 Points[8], MinLight = CVector3(FLT_MAX), MaxLight = CVector3(FLT_MAX); for(int i = 0; i<8;++i){ Points[i] = Points[i] * WorldToShadowMapMatrix; MinLight = Math::Min(Points[i],MinLight); MaxLight = Math::Max(Points[i],MaxLight); } AABox box(MinLight,MaxLight); I don't think this is the right way to do it. The near plain probably has to extend into the direction of the light source to include potentional shadow casters. I've read the Microsoft article about cascaded shadow maps http://msdn.microsoft.com/en-us/library/windows/desktop/ee416307%28v=vs.85%29.aspx which also includes some sample code. But they seem to use the scenes AABB to determine the near and far plane which I can't since i cant access this information from the funtion I'm working in. Could you guys please link some example code which shows the calculation of such frustum? Thanks in advance! Additional questio: is there a way to construct a WorldToFrustum matrix that represents the above transformation?

• OpenWorld Day 1

  - by Antony Reynolds

  A Day in the Life of an OpenWorld Attendee Part I Lots of people are blogging insightfully about OpenWorld so I thought I would provide some non-insightful remarks to buck the trend! With 50,000 attendees I didn’t expect to bump into too many people I knew, boy was I wrong!  I walked into the registration area and immediately was hailed by a couple of customers I had worked with a few months ago.  Moving to the employee registration area in a different hall I bumped into a colleague from the UK who was also registering.  As soon as I got my badge I bumped into a friend from Ireland!  So maybe OpenWorld isn’t so big after all! First port of call was Larrys Keynote.  As always Larry was provocative and thought provoking.  His key points were announcing the Oracle cloud offering in IaaS, PaaS and SaaS, pointing out that Fusion Apps are cloud enabled and finally announcing the 12c Database, making a big play of its new multi-tenancy features.  His contention was that multi-tenancy will simplify cloud development and provide better security by providing DB level isolation for applications and customers. Next day, Monday, was my first full day at OpenWorld.  The first session I attended was on monitoring of OSB, very interesting presentation on the benefits achieved by an Illinois area telco – US Cellular.  Great discussion of why they bought the SOA Management Packs and the benefits they are already seeing from their investment in terms of improved provisioning and time to market, as well as better performance insight and assistance with capacity planning. Craig Blitz provided a nice walkthrough of where Coherence has been and where it is going. Last night I attended the BOF on Managed File Transfer where Dave Berry replayed Oracles thoughts on providing dedicated Managed File Transfer as part of the 12c SOA release.  Dave laid out the perceived requirements and solicited feedback from the audience on what if anything was missing.  He also demoed an early version of the functionality that would simplify setting up MFT in SOA Suite and make tracking activity much easier. So much for Day 1.  I also ran into scores of old friends and colleagues and had a pleasant dinner with my friend from Ireland where I caught up on the latest news from Oracle UK.  Not bad for Day 1!

• Multiple render targets and gamma correctness in Direct3D9

  - by Mario

  Let's say in a deferred renderer when building your G-Buffer you're going to render texture color, normals, depth and whatever else to your multiple render targets at once. Now if you want to have a gamma-correct rendering pipeline and you use regular sRGB textures as well as rendertargets, you'll need to apply some conversions along the way, because your filtering, sampling and calculations should happen in linear space, not sRGB space. Of course, you could store linear color in your textures and rendertargets, but this might very well introduce bad precision and banding issues. Reading from sRGB textures is easy: just set SRGBTexture = true; in your texture sampler in your HLSL effect code and the hardware does the conversion sRGB-linear for you. Writing to an sRGB rendertarget is theoretically easy, too: just set SRGBWriteEnable = true; in your effect pass in HLSL and your linear colors will be converted to sRGB space automatically. But how does this work with multiple rendertargets? I only want to do these corrections to the color textures and rendertarget, not to the normals, depth, specularity or whatever else I'll be rendering to my G-Buffer. Ok, so I just don't apply SRGBTexture = true; to my non-color textures, but when using SRGBWriteEnable = true; I'll do a gamma correction to all the values I write out to my rendertargets, no matter what I actually store there. I found some info on gamma over at Microsoft: http://msdn.microsoft.com/en-us/library/windows/desktop/bb173460%28v=vs.85%29.aspx For hardware that supports Multiple Render Targets (Direct3D 9) or Multiple-element Textures (Direct3D 9), only the first render target or element is written. If I understand correctly, SRGBWriteEnable should only be applied to the first rendertarget, but according to my tests it doesn't and is used for all rendertargets instead. Now the only alternative seems to be to handle these corrections manually in my shader and only correct the actual color output, but I'm not totally sure, that this'll not have any negative impact on color correctness. E.g. if the GPU does any blending or filtering or multisampling after the Linear-sRGB conversion... Do I even need gamma correction in this case, if I'm just writing texture color without lighting to my rendertarget? As far as I know, I DO need it because of the texture filtering and mip sampling happening in sRGB space instead, if I don't correct for it. Anyway, it'd be interesting to hear other people's solutions or thoughts about this.

• SSAS Tabular Workshop online and other upcoming dates (and updates!) #ssas #tabular

  - by Marco Russo (SQLBI)

  After many conferences and travels, this summer I had some time to write and prepare new sessions for the next wave of conferences. In reality I am just doing that, even if I already restarted traveling for consulting and training. So expect new content about DAX and Tabular coming in the next months! Starting to see real customer adopting Tabular is showing many new challenges and there is still a lot to learn and to create. If you still didn’t started working on Tabular, well, you should. As I always say, as a BI developer you should be able to choose between Tabular and Multidimensional, and in order to do that you should know both of them! One thing that I don’t like very much about marketing is that “Tabular is simpler”, because it’s often translated in “Tabular is for simple projects” when this last statement is not true. Actually, I see a lot of good reasons to adopt Tabular in complex data models, especially in non-traditional scenarios. I know, this is because I love to understand what are the actual limits of a technology, and I’m learning that there is simple a lot of space of improvement also for Tabular. It’s already fast, but it could be faster! How can you start? Well, first of all, by reading our book. Then, by attending to our SSAS Tabular workshop. There is an online edition of the workshop on September 3-4, 2012 (hurry up if you want to register), and there are already several dates planned for the next months (and others will be added soon!). And, of course, by installing SQL Server 2012 and trying to create models over your databases. If you are too lazy, just start with PowerPivot. As soon as you start working with Tabular or PowerPivot, you will see that there is one important skill you need: learning DAX. In the next few days I should publish an article that I’m finishing these days about best practices using SUMMARIZE and ADDCOLUMNS. If only someone published this article one year ago, I would have saved many hours of my life. But, you know, flight manuals are written in blood… and someone has to write! Stay tuned.

• WinMo&rsquo;s Demise: Notifying Next of &ldquo;Kin&rdquo;

  - by andrewbrust

  This past Monday, April 12th, Visual Studio 2010 was launched.  And on that same day, Microsoft also launched a new line of  mobile phone handsets, called Kin.  The two product launches are actually connected, but only by what they do not have in common, and what they commonly lack. On the former point: VS 2010 had released to manufacturing a couple weeks prior to its launch.  The Kin phones, meanwhile are not yet available.  We don’t even know what they will cost.  (And I think cost will be a major factor in Kin’s success…I told ChannelWeb’s Yara Souza so in this article). What do the two products both lack? Simple: Windows Mobile 6.x. For example, Kin seems to be based on the same platform as Windows Phone 7 (albeit a subset).  And VS 2010 does not support .NET Compact Framework development, which means no .NET development support for WinMo 6.x and earlier. So I guess April 12th marks Windows Phone “clean slate day.”  If you want to develop for the old phone platform, you will need to use the old version of Visual Studio (i.e. 2008).  Luckily VS 2010 and 2008 can be installed side-by-side.  But I doubt that’s much consolation to developers who still target WinMo 6.5 and earlier. Remember, WinMo isn’t just about the phone.  There are all sorts of non-telephony mobile devices, including ruggedized Pocket PC-style instruments, bar code readers and shop-floor-deployed units that don’t run Windows Phone 7 and couldn’t, even if they wanted to. Where will developers in these markets go?  I would guess some will stick with WinMo 6.x and earlier, until Windows Phone 7 can handle their workloads, assuming that does indeed happen.  Others will likely go to Google’s Android platform. For OEMs and developers who need a customizable mobile software stack, Android is turning out to be out-WinMo-ing WinMo.  As I wrote in this post, Google took Microsoft’s model (minus the licensing fees) and combined it with a modern SmartPhone feature set (rather than a late 90s/early oughts PDA paradigm), to great success.  You might say Google embraced and extended. You might also say Microsoft shunned and withdrew.

• Video stutter when using external drive

  - by psion

  When using boxee to play video files off of an external western digital 1TB drive formatted NTFS, I notice a slight stutter in the video every 5-10 seconds. When using mplayer, it doesn't stutter as often, but it still stutters occasionally. If I play the video off of the local sata drive, it plays fine even in boxee. I use this computer as my HTPC and I just switched from windows to linux on it. In windows, I never had any sort of stutter playing movies from the drive. I am using the latest intel graphics drivers (for the intel GMA 950) root@eee-htpc:/home/htpc# grep wd /etc/mtab /dev/sdb1 /mnt/wd2 fuseblk rw,nosuid,nodev,allow_other,blksize=512 0 0 I notice that despite trying to use ntfs or ntfs-3g, ubuntu uses ntfs-fuse which I've heard is slower. /dev/sdb1: Timing buffered disk reads: 80 MB in 3.07 seconds = 26.08 MB/sec root@eee-htpc:/mnt/wd2# dd if=/dev/zero of=./120mb bs=1024 count=120000 root@eee-htpc:/mnt/wd2# time mv ./120mb /home/htpc real 0m2.095s user 0m0.016s sys 0m0.736s Even though fuse has a reputation for being slow, it should easily be fast enough for playing standard definition video files. So why the video stutter? edit: The issue seems to be overhead cpu usage from either playing off of a usb device or ntfs/fuse. Watching CPU usage with top, local files use 10-40% CPU. Watching the same video on the external formatted ntfs, it spikes to 170% (over 100% because of hyperthreading). To me it seems like it must be overhead from the fuse driver, though I don't know if it has more or less overhead than ntfs-3g. It's a EEEBox B202 that has an atom 270, so not exactly the most powerful out there. edit2: I believe the solution would be to use non-fuse drivers or different fuse drivers. so far I have not been able to. edit3: I've probably edited this more times than I should, but as an update I have upgraded ntfs drivers to ntfs-3g 2010.8.8 external FUSE 28 - Third Generation NTFS Driver using the following PPA - ppa:x3lectric/team-iquik-releases. When first opening a video file in boxee that's on ntfs there's still the same amount of lag. After a few minutes of video, the lag seems to go away and the cpu usage comes down to 10-40%. Every so often though, it begins to stutter again. Also, if I skip ahead/back in the file, it begins to stutter a lot.

• Dissing Architects, or "What's wrong with the coffee?"

  - by Bob Rhubart

  In my conversations with people in architect roles, tales of animosity, disrespect, and outright hostility aren't uncommon. And it's clear that in more than a few organizations architects regularly face a tough uphill climb. For architects with the requisite combination of technical, organizational, and people skills, that rough treatment is grossly undeserved. But tales of unqualified people in positions up and down the IT food chain are also easy to come by. So what's the other side of the architect story? Are some architects tarnishing the role and making life miserable for their more qualified colleagues? The various quotes included below were culled from a variety of sources. The criticism is harsh, and the people behind these quotes clearly have issues with architects. Still, whether based on mere opinion or actual experience, the comments shed some light on behaviors that should raise red flags for anyone pursuing a career as an architect. If you're an architect, and you've ever noticed that your coffee tastes like window cleaner, or your car is repeatedly keyed, or no one ever holds the elevator for you, maybe you need to do a little soul searching... Those Who Can, Code; Those Who Can't, Architect | Joe Winchester [May 18, 2007] "At the moment there seems to be an extremely unhealthy obsession in software with the concept of architecture. A colleague of mine, a recent graduate, told me he wished to become a software architect. He was drawn to the glamour of being able to come up with grandiose ideas - sweeping generalized designs, creating presentations to audiences of acronym addicts, writing esoteric academic papers, speaking at conferences attended by headless engineers on company expense accounts hungrily seeking out this year's grail, and creating e-mails with huge cc lists from people whose signature footer is more interesting than the content. I tried to re-orient him into actually doing some coding, to join a team that has a good product and keen users both of whom are pushing requirements forward, to no avail. Somehow the lure of being an architecture astronaut was too strong and I lost him to the dark side." Don't Let Architecture Astronauts Scare You | Joel Spolsky [April 21, 2001] "It's very hard to get them to write code or design programs, because they won't stop thinking about Architecture. They're astronauts because they are above the oxygen level, I don't know how they're breathing. They tend to work for really big companies that can afford to have lots of unproductive people with really advanced degrees that don't contribute to the bottom line. Remember that the architecture people are solving problems that they think they can solve, not problems which are useful to solve." Non Coding Architects Suck | Richard Henderson [May 24, 2010] "If a guy with a badge saying 'system architect' looks blank on low-level issues then he is not an architect, he is a business-analyst who went on a course. He will probably wax lyrical on all things high-level and 'important.' He will produce lovely object hierarchies without a clue to implementation. He will have a moustache and play golf." Architects Play Golf | Sunir Shah [August 15, 2012] "Often arrogant architects are difficult to get a hold of during the implementation phase because they no longer feel the need to stick around. Especially around midnight when most of the poor sob [sic] developers are still banging away. After all, they've already solved the problem--the rest is just an implementation exercise." Engineer vs Architect(Part of a discussion on the IT Architect Network Group on LinkedIn) "[An] architect spends his time producing white papers full of acronyms he does not understand but that impress his boss [while the] engineer keeps his head down and does the actual job." Architects Don't Code | [Author Unknown] "Faulty belief: System Architects don't need to code anymore. They know what they are talking about by virtue of the fact that they are System Architects."

• Some OBI EE Tricks and Tips in the Admin Tool By Gerry Langton

  - by hamsun

  How to set the log level from a Session variable Initialization block As we know it is normal to set the log level non-zero for a particular user when we wish to debug problems. However sometimes it is inconvenient to go into each user’s properties in the Admin tool and update the log level. So I am showing a method which allows the log level to be set for all users via a session initialization block. This is particularly useful for anyone wanting an alternative way to set the log level. The screen shots shown are using the OBIEE 11g SampleApp demo but are applicable to any environment. Open the appropriate rpd in on-line mode and navigate to Manage Variables. Select Session Initialization Blocks, right click in the white space and create a New Initialization Block. I called the Initialization block Set_Loglevel . Now click on ‘Edit Data Source’ to enter the SQL. Chose the ‘Use OBI EE Server’ option for the SQL. This means that the SQL provided must use tables which have been defined in the Physical layer of the RPD, and whilst there is no need to provide a connection pool you must work in On-Line mode. The SQL can access any of the RPD tables and is purely used to return a value of 2. The ‘Test’ button confirms that the SQL is valid. Next, click on the ‘Edit Data Target’ button to add the LOGLEVEL variable to the initialization block. Check the ‘Enable any user to set the value’ option so that this will work for any user. Click OK and the following message will display as LOGLEVEL is a system session variable: Click ‘Yes’. Click ‘OK’ to save the Initialization block. Then check in the On-LIne changes. To test that LOGLEVEL has been set, log in to OBIEE using an administrative login (e.g. weblogic) and reload server metadata, either from the Analysis editor or from Administration > Reload Files and Metadata link. Run a query then navigate to Administration > Manage Sessions and click ‘View Log’ for the query just issued (which should be approximately the last in the list). A log file should exist and with LOGLEVEL set to 2 should include both logical and physical sql. If more diagnostic information is required then set LOGLEVEL to a higher value. If logging is required only for a particular analysis then an alternative method can be used directly from the Analysis editor. Edit the analysis for which debugging is required and click on the Advanced tab. Scroll down to the Advanced SQL clauses section and enter the following in the Prefix box: SET VARIABLE LOGLEVEL = 2; Click the ‘Apply SQL’ button. The SET VARIABLE statement will now prefix the Analysis’s logical SQL. So that any time this analysis is run it will produce a log. You can find information about training for Oracle BI EE products here or in the OU Learning Paths. Please send me an email at [email protected] if you have any further questions. About the Author: Gerry Langton started at Siebel Systems in 1999 working as a technical instructor teaching both Siebel application development and also Siebel Analytics (which subsequently became Oracle BI EE). From 2006 Gerry has worked as Senior Principal Instructor within Oracle University specialising in Oracle BI EE, Oracle BI Publisher and Oracle Data Warehouse development for BI.

• Tellago releases a RESTful API for BizTalk Server business rules

  - by Charles Young

  Jesus Rodriguez has blogged recently on Tellago Devlabs' release of an open source RESTful API for BizTalk Server Business Rules.   This is an excellent addition to the BizTalk ecosystem and I congratulate Tellago on their work.   See http://weblogs.asp.net/gsusx/archive/2011/02/08/tellago-devlabs-a-restful-api-for-biztalk-server-business-rules.aspx   The Microsoft BRE was originally designed to be used as an embedded library in .NET applications. This is reflected in the implementation of the Rules Engine Update (REU) Service which is a TCP/IP service that is hosted by a Windows service running locally on each BizTalk box. The job of the REU is to distribute rules, managed and held in a central database repository, across the various servers in a BizTalk group.   The engine is therefore distributed on each box, rather than exploited behind a central rules service.   This model is all very well, but proves quite restrictive in enterprise environments. The problem is that the BRE can only run legally on licensed BizTalk boxes. Increasingly we need to deliver rules capabilities across a more widely distributed environment. For example, in the project I am working on currently, we need to surface decisioning capabilities for use within WF workflow services running under AppFabric on non-BTS boxes. The BRE does not, currently, offer any centralised rule service facilities out of the box, and hence you have to roll your own (and then run your rules services on BTS boxes which has raised a few eyebrows on my current project, as all other WCF services run on a dedicated server farm ).   Tellago's API addresses this by providing a RESTful API for querying the rules repository and executing rule sets against XML passed in the request payload. As Jesus points out in his post, using a RESTful approach hugely increases the reach of BRE-based decisioning, allowing simple invocation from code written in dynamic languages, mobile devices, etc.   We developed our own SOAP-based general-purpose rules service to handle scenarios such as the one we face on my current project. SOAP is arguably better suited to enterprise service bus environments (please don't 'flame' me - I refuse to engage in the RESTFul vs. SOAP war). For example, on my current project we use claims based authorisation across the entire service bus and use WIF and WS-Federation for this purpose.   We have extended this to the rules service. I can't release the code for commercial reasons :-( but this approach allows us to legally extend the reach of BRE far beyond the confines of the BizTalk boxes on which it runs and to provide general purpose decisioning capabilities on the bus.   So, well done Tellago.   I haven't had a chance to play with the API yet, but am looking forward to doing so.

• Attunity Oracle CDC Solution for SSIS - Beta

  We in no way work for Attunity but we were asked to test drive a beta version of their Oracle CDC solution for SSIS.  Everybody should know that moving more data than you need to takes too much time and uses resources that may better be employed doing something else.  Change data Capture is a technology that is designed to help you identify only the data that has had something done to it and you can therefore move only what is needed.  Microsoft have implemented this exact functionality into SQL server 2008 and I really like it there.  Attunity though are doing it on Oracle. DISCLAIMER: This is a BETA release and some of the parts are a bit ugly/difficult to work with.  The idea though is definitely right and the product once working does exactly what it says on the tin.  They have always been helpful to me when I have had a problem with the product and if that continues then beta testing pain should be eased somewhat. In due course I am going to be doing some videos around me using the product.  If you use Oracle and SSIS then give it a go. Here is their product description.   Attunity is a Microsoft SQL Server technology partner and the creator of the Microsoft Connectors for Oracle and Teradata, currently available in SQL Server 2008 Enterprise Edition. Attunity released a beta version of the Attunity Oracle-CDC for SSIS, a product that integrates continually changing Oracle data into SSIS, efficiently and in real-time. Attunity designed the product and integrated it into SSIS to create the simple creation of change data capture (CDC) solutions, accelerate implementation time, and reduce resources and costs. They also utilize log-based CDC so the solution has minimal impact on the Oracle source system. You can use the product to implement enterprise-class data replication, synchronization, and real-time business intelligence (BI) and data warehousing projects, quickly and efficiently, leveraging their existing SQL Server investments and resource skills. Attunity architected the product specifically for the Microsoft SSIS developer community and the product is available for both SQL Server 2005 and SQL Server 2008. It offers the following key capabilities: · Log-based, non-intrusive Oracle CDC · Full integration into SSIS and the Business Intelligence Developer Studio · Automatic generation of SSIS packages for CDC as well as full-loads of Oracle data · Filtering of Oracle tables and columns at the source · Monitoring and control of CDC processing Click to learn more and download the beta.

• How to sort a ListView control by a column in Visual C#

  - by bconlon

  Microsoft provide an article of the same name (previously published as Q319401) and it shows a nice class 'ListViewColumnSorter ' for sorting a standard ListView when the user clicks the column header. This is very useful for String values, however for Numeric or DateTime data it gives odd results. E.g. 100 would come before 99 in an ascending sort as the string compare sees 1 < 9. So my challenge was to allow other types to be sorted. This turned out to be fairly simple as I just needed to create an inner class in ListViewColumnSorter which extends the .Net CaseInsensitiveComparer class, and then use this as the ObjectCompare member's type. Note: Ideally we would be able to use IComparer as the member's type, but the Compare method is not virtual in CaseInsensitiveComparer , so we have to create an exact type: public class ListViewColumnSorter : IComparer {     private CaseInsensitiveComparer ObjectCompare;     private MyComparer ObjectCompare;     ... rest of Microsofts class implementation... } Here is my private inner comparer class, note the 'new int Compare' as Compare is not virtual, and also note we pass the values to the base compare as the correct type (e.g. Decimal, DateTime) so they compare correctly: private class MyComparer : CaseInsensitiveComparer {     public new int Compare(object x, object y)     {         try         {             string s1 = x.ToString();             string s2 = y.ToString();               // check for a numeric column             decimal n1, n2 = 0;             if (Decimal.TryParse(s1, out n1) && Decimal.TryParse(s2, out n2))                 return base.Compare(n1, n2);             else             {                 // check for a date column                 DateTime d1, d2;                 if (DateTime.TryParse(s1, out d1) && DateTime.TryParse(s2, out d2))                     return base.Compare(d1, d2);             }         }         catch (ArgumentException) { }           // just use base string compare         return base.Compare(x, y);     } } You could extend this for other types, even custom classes as long as they support ICompare. Microsoft also have another article How to: Sort a GridView Column When a Header Is Clicked that shows this for WPF, which looks conceptually very similar. I need to test it out to see if it handles non-string types. #

• #OOW 2012: Big Data and The Social Revolution

  - by Eric Bezille

  As what was saying Cognizant CSO Malcolm Frank about the "Futur of Work", and how the Business should prepare in the face of the new generation  not only of devices and "internet of things" but also due to their users ("The Millennials"), moving from "consumers" to "prosumers" :  we are at a turning point today which is bringing us to the next IT Architecture Wave. So this is no more just about putting Big Data, Social Networks and Customer Experience (CxM) on top of old existing processes, it is about embracing the next curve, by identifying what processes need to be improve, but also and more importantly what processes are obsolete and need to be get ride of, and new processes put in place. It is about managing both the hierarchical and structured Enterprise and its social connections and influencers inside and outside of the Enterprise. And this does apply everywhere, up to the Utilities and Smart Grids, where it is no more just about delivering (faster) the same old 300 reports that have grown over time with those new technologies but to understand what need to be looked at, in real-time, down to an hand full relevant reports with the KPI relevant to the business. It is about how IT can anticipate the next wave, and is able to answers Business questions, and give those capabilities in real-time right at the hand of the decision makers... This is the turning curve, where IT is really moving from the past decade "Cost Center" to "Value for the Business", as Corporate Stakeholders will be able to touch the value directly at the tip of their fingers. It is all about making Data Driven Strategic decisions, encompassed and enriched by ALL the Data, and connected to customers/prosumers influencers. This brings to stakeholders the ability to make informed decisions on question like : “What would be the best Olympic Gold winner to represent my automotive brand ?”... in a few clicks and in real-time, based on social media analysis (twitter, Facebook, Google+...) and connections link to my Enterprise data. A true example demonstrated by Larry Ellison in real-time during his yesterday’s key notes, where “Hardware and Software Engineered to Work Together” is not only about extreme performances but also solutions that Business can touch thanks to well integrated Customer eXperience Management and Social Networking : bringing the capabilities to IT to move to the IT Architecture Next wave. An example, illustrated also todays in 2 others sessions, that I had the opportunity to attend. The first session bringing the “Internet of Things” in Oil&Gaz into actionable decisions thanks to Complex Event Processing capturing sensors data with the ready to run IT infrastructure leveraging Exalogic for the CEP side, Exadata for the enrich datasets and Exalytics to provide the informed decision interface up to end-user. The second session showing Real Time Decision engine in action for ACCOR hotels, with Eric Wyttynck, VP eCommerce, and his Technical Director Pascal Massenet. I have to close my post here, as I have to go to run our practical hands-on lab, cooked with Olivier Canonge, Christophe Pauliat and Simon Coter, illustrating in practice the Oracle Infrastructure Private Cloud recently announced last Sunday by Larry, and developed through many examples this morning by John Folwer. John also announced today Solaris 11.1 with a range of network innovation and virtualization at the OS level, as well as many optimizations for applications, like for Oracle RAC, with the introduction of the lock manager inside Solaris Kernel. Last but not least, he introduced Xsigo Datacenter Fabric for highly simplified networks and storage virtualization for your Cloud Infrastructure. Hoping you will get ready to jump on the next wave, we are here to help...

• Configurable Objects - Introduction

  - by Anthony Shorten

  One of the interesting facilities in the framework is Configurable Object functionality (it is also known as Task Optimization and also known as Cool Tools). The idea is that any implementation can create their own views of the base product objects and services and implement functionality against those new views. For example, in Oracle Utilities Customer Care and Billing, there is a Person object. That object is used to store and manage information about individuals as well as companies. In the base product you would use the Person Maintenance screen and fill in some of the screen when you wanted to register or maintain and individual as well and fill out other parts of the screen when you wanted to register or maintain a company. This can be somewhat confusing to some customers. Using Configurable Objects this can be simplified. A business object can be created that is a view of the any object. For example, you could create a Human business object which would cover the aspects of the Person object pertaining to an individual and a Company business object to cover the aspects unique to a company. Even the tag names (i.e. Field Names) in the object can be changed to be more what the implementation is familiar with. The object can also restructure the object. For example, a common identifier for an individual in the USA is the Social Security number, this value is a Person Identifier (as this varies in each country). In the new Human object you can remap the Person Identifier as a Social Security number. To define a Business Object you use a schema editor built into the browser user interface and use a mapping language to setup the business objects. An example of the language is shown below in an extract of the schema for the Human business object. As you can see there are mapping as well as formatting and other tags. This information can be built manually or using a wizard which generates the base structure for you to alter. This is all stored as meta data when saved. Once a Business object is built it can be used as basis for code, other business objects (we support inheritance), called by a screen (called a UI Map) or even as a Web Service. This is just a start with Configurable Objects as you can also create views of base services called Business Services, Service Scripts used for non-object or complex object processing (as well as other things), UI Maps used for screens and Data Areas to reuse definitions across multiple objects. Configurable Objects are powerful and I only really touched on them here. Over the next few months I hope to add lots more entries about them.

• Win7 is not a tablet OS, no matter what the boys in Redmond think.

  - by John Conwell

  Despite what execs at Microsoft think, Windows 7 is NOT a tablet OS.  Just because you can install some software (or OS) on a device, doesn't mean that device is meant to run that software.  This seems to be the step that the non-engineer execs at Microsoft have seem to not understood.  In order to seamlessly work with a device, the software needs to be designed with that device in mind.  That has been the problem with the Windows PDA platform, the Windows Mobil platform, and now with trying to force fit Windows 7 on a tablet.  Its just not designed for that style of interaction.   Windows is designed to be interacted with via a mouse and keyboard.  In fact, it is brilliant at that.  But, It is NOT designed to be interacted with by your fingers.  And that is why the Windows tablet failed 10 years ago, and why it will fail today.  Its not the hardware's fault like Microsoft claimed 10 years ago.  Its the User Interaction design that failed. And this is why the iPhone and Android OS's work wonderfully on a tablet.  The user interaction was designed for small screens, navigated by big fat fingers.  I love these OS's and how I interact with them.  And when I play with a touch screen Windows 7 device, I am feel like I'm playing with a brittle wana-be.  And its not the hardware's fault.  The touchscreen is very responsive.  I actually like the hardware.  But the OS and the software are just not designed to be interacted with, with my big fat fingers.  In order to be successful, Microsoft needs to start from scratch, and build a platform AND SOFTWARE specifically for use by fingers.  Thats why everyone was so excited when they though Microsoft was going to release the Courier tablet.  Because it looked like a totally different platform.  Something that might actually work.  But Windows 7...I hate to burst your bubble, but you are not a touch platform.

• Tuxedo Load Balancing

  - by Todd Little

  A question I often receive is how does Tuxedo perform load balancing.  This is often asked by customers that see an imbalance in the number of requests handled by servers offering a specific service. First of all let me say that Tuxedo really does load or request optimization instead of load balancing.  What I mean by that is that Tuxedo doesn't attempt to ensure that all servers offering a specific service get the same number of requests, but instead attempts to ensure that requests are processed in the least amount of time.   Simple round robin "load balancing" can be employed to ensure that all servers for a particular service are given the same number of requests.  But the question I ask is, "to what benefit"?  Instead Tuxedo scans the queues (which may or may not correspond to servers based upon SSSQ - Single Server Single Queue or MSSQ - Multiple Server Single Queue) to determine on which queue a request should be placed.  The scan is always performed in the same order and during the scan if a queue is empty the request is immediately placed on that queue and request routing is done.  However, should all the queues be busy, meaning that requests are currently being processed, Tuxedo chooses the queue with the least amount of "work" queued to it where work is the sum of all the requests queued weighted by their "load" value as defined in the UBBCONFIG file.  What this means is that under light loads, only the first few queues (servers) process all the requests as an empty queue is often found before reaching the end of the scan.  Thus the first few servers in the queue handle most of the requests.  While this sounds non-optimal, in fact it capitalizes on the underlying operating systems and hardware behavior to produce the best possible performance.  Round Robin scheduling would spread the requests across all the available servers and thus require all of them to be in memory, and likely not share much in the way of hardware or memory caches.  Tuxedo's system maximizes the various caches and thus optimizes overall performance.  Hopefully this makes sense and now explains why you may see a few servers handling most of the requests.  Under heavy load, meaning enough load to keep all servers that can handle a request busy, you should see a relatively equal number of requests processed.  Next post I'll try and cover how this applies to servers in a clustered (MP) environment because the load balancing there is a little more complicated.

• JCP Awards 10 Year Retrospective

  - by Heather VanCura

  As we celebrate 10 years of JCP Program Award recognition in 2012,  take a look back in the Retrospective article covering the history of the JCP awards.  Most recently, the JCP awards were  celebrated at JavaOne Latin America in Brazil, where SouJava was presented the JCP Member of the Year Award for 2012 (won jointly with the London Java Community) for their contributions and launch of the Global Adopt-a-JSR Program. This is also a good time to honor the JCP Award Nominees and Winners who have been designated as Star Spec Leads.  Spec Leads are key to the Java Community Process (JCP) program. Without them, none of the Java Specification Requests (JSRs) would have begun, much less completed and become implemented in shipping products.  Nominations for 2012 Start Spec Leads are now open until 31 December. The Star Spec Lead program recognizes Spec Leads who have repeatedly proven their merit by producing high quality specifications, establishing best practices, and mentoring others. The point of such honor is to endorse the good work that they do, showcase their methods for other Spec Leads to emulate, and motivate other JCP program members and participants to get involved in the JCP program. Ed Burns – A Star Spec Lead for 2009, Ed first got involved with the JCP program when he became co-Spec Lead of JSR 127, JavaServer Faces (JSF), a role he has continued through JSF 1.2 and now JSF 2.0, which is JSR 314. Linda DeMichiel – Linda thus involved in the JCP program from its very early days. She has been the Spec Lead on at least three JSRs and an EC member for another three. She holds a Ph.D. in Computer Science from Stanford University. Gavin King – Nominated as a JCP Outstanding Spec Lead for 2010, for his work with JSR 299. His endorsement said, “He was not only able to work through disputes and objections to the evolving programming model, but he resolved them into solutions that were more technically sound, and which gained support of its pundits.” Mike Milikich –  Nominated for his work on Java Micro Edition (ME) standards, implementations, tools, and Technology Compatibility Kits (TCKs), Mike was a 2009 Star Spec Lead for JSR 271, Mobile Information Device Profile 3. David Nuescheler – Serving as the CTO for Day Software, acquired by Adobe Systems, David has been a key player in the growth of the company’s global content management solution. In 2002, he became Spec Lead for JSR 170, Content Repository for Java Technology API, continuing for the subsequent version, JSR 283. Bill Shannon – A well-respected name in the Java community, Bill came to Oracle from Sun as a Distinguished Engineer and is still performing at full speed as Spec Lead for JSR 342, Java EE 7,  as an alternate EC member, and hands-on problem solver for the Java community as a whole. Jim Van Peursem – Jim holds a PhD in Computer Engineering. He was part of the Motorola team that worked with Sun labs on the Spotless VM that became the KVM. From within Motorola, Jim has been responsible for many aspects of Java technology deployment, from an independent Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP) implementations, to handset development, to working with the industry in defining many related standards. Participation in the JCP Program goes well beyond technical proficiency. The JCP Awards Program is an attempt to say “Thank You” to all of the JCP members, Expert Group Members, Spec Leads, and EC members who give their time to contribute to the evolution of Java technology.

Cloud, automation drive new growth in SOA governance market | ZDNet "SOA governance tools and processes learned over the past decade are now underpinning cloud projects as they scale across enterprises," reports Joe McKendrick. But there remains a lack of understanding about SOA Governance. DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video. Oracle OpenWorld 2012 Hands-on Lab: "Leading Your Everyday Application Integration Projects with Enterprise SOA" Yet another session to squeeze into your already-jammed Oracle OpenWorld schedule. This hands-on lab focuses on how "Oracle Enterprise Repository, Oracle Application Integration Architecture (AIA) Foundation Pack, and Oracle SOA Suite work together to help you drive your enterprisewide integration projects."

As McKendrick puts it: "IT professionals are under considerable pressure to deliver more value to the business, versus being good at coding and testing and deploying and integrating." Running RichFaces on WebLogic 12c | Markus Eisele "With all the JMS magic and the different provider checks in the showcase this has become some kind of a challenge to simply build and deploy it," says Oracle ACE Director Markus Eisele. His detailed post will help you to meet that challenge. Thought for the Day "Less is more." — Ludwig Mies van der Rohe (March 27, 1886 – August 17, 1969) Source: BrainyQuote.com
