• So&hellip; What is a SharePoint Developer?

  - by Mark Rackley

  A few days ago Stacy Draper and I were chatting about what it means to be a SharePoint Developer. That actually turns about to be a conversation with lots of shades of grey. Stacy thought it would make a good blog post… well, I can’t promise this to be a GOOD blog post… So, anyway, I decided to let off a little bomb this morning by posting the following tweet on Twitter: @mrackley: Can someone be considered a SharePoint Developer if all they know how to do is work in SPD? Now, I knew this is a debate that has been going on since the first SharePoint Designer User put SharePoint Developer on their resume. There are probably several blogs out there on the subject, but with the wildfire that is jQuery and a few other new features out there I believe it is an important subject to tackle again. I got a lot of great feedback as well on Twitter. The entire twitter conversation is at the end of this blog posting. Thanks everyone for their opinions. Who cares? Why does it matter? Can’t we all just get along? Yes it matters… everything must be labeled and put in it’s proper place. Pigeon holing is the only way to go!  Just kidding.. I’m not near that anal, but yes! It is important to be able to properly identify the skill set of those people on your team and correctly identify the role you are wanting to hire. Saying you are a “SharePoint Developer” is just too vague and just barely begins to answer the question. Also, knowing who’s on your team and what they can do will ensure you give your clients the best people for the job. A Developer writes code right? So, a Developer uses Visual Studio! Whoa, hold on there Sparky. Even if I concede that to be a developer you have to write code then you still can’t say a SharePoint Developer has to use Visual Studio.  So, you can spell C#, how well can you write XSLT? How’s your jQuery? Sorry bud, that’s code whether you like it or not. There are many ways to write code in SharePoint that have nothing to do with cracking open Visual Studio. So, what are the different ways to develop in SharePoint then? How many different ways can you “develop” in SharePoint?? A lot… Out of the box features In SharePoint you can create a site, create a custom list on that site, do basic calculations in a calculated column, set up alerts, and add all sorts of web parts to a page. Let’s face it.. that IS development! javaScript/jQuery Perhaps you’ve heard by now about this thing called jQuery? It’s all over the place and the answer to a lot of people’s prayers. However be careful, with great power comes great responsibility. Remember, javaScript is executed on the client side and if you abuse it your performance could be affected. Also, Marc Anderson (@sympmarc) wrote a pretty awesome javaScript library called SPServices.  This allows you to access SharePoint’s Web Services using jQuery. How freakin cool is that? With these tools at your disposal the number of things you CAN’T do without Visual Studio grows smaller and smaller. This is definitely development no matter what anyone else says and there is no Visual Studio involved. SharePoint Designer Ahhh.. The cause of and the answer to all of your SharePoint development problems. With SharePoint Designer you can use DataView Web Parts, develop (there’s that word again) your branding, and even connect to external datasources.  There’s a lot you can do in SharePoint Designer. It’s got it’s shortcomings, but it is an invaluable tool in the SharePoint developers toolbox. InfoPath So, can InfoPath development really be considered SharePoint development? I would say yes. You can connect to SharePoint lists, populate fields in a SharePoint list, and even write code in InfoPath. Sounds like SharePoint development to me. Visual Studio – Web Services/WCF So, get this. You can write code for SharePoint and not have a clue what the 12 hive is, what “site actions” means, or know how to do ANYTHING in SharePoint? Poppycock! You say? SharePoint Web Services I say… With SharePoint Web Services you can totally interact with SharePoint without knowing anything about SharePoint. I don’t recommend it of course, but it’s possible. What can you write using SharePoint Web Services? How about a little application called SharePoint Designer? Visual Studio – Object Model And here we are finally:  the SharePoint Object Model.  When you hear “SharePoint Developer” most people think of someone opening Visual Studio and creating a custom web part, workflow, event receiver, etc.. etc.. but I hope that by now I have made the point that this is NOT the only form of SharePoint Development! Again… Who cares? Just crack open Visual Studio for everything! Problem solved! Let’s ponder for a moment, shall we? The business comes to you with a requirement that involves some pretty fancy business calculations, and a complicated view that they do NOT want to look like SharePoint. “No Problem” you proclaim you mighty SharePoint Developer. You go back to your cube, chuckle at the latest Dilbert comic, and crack open Visual Studio. Then you build your custom web part… fight with all the deployment, migration, and UAT that you must go through and proclaim victory two weeks later!!!! Well done my good sir/ma’am! Oh wait… it turns out Sally who is not a “developer” did the exact same thing with a Dataview web part and some jQuery and it’s been in production for two weeks? #CockinessFail I know there are many ASP.NET developers out there that can create a custom control and wrap it to be a SharePoint Web Part.  That does NOT mean they are SharePoint Developers though as far as I’m concerned and I personally would much rather have someone on my team that can manipulate the heck (yes, I said ‘heck’) out of SharePoint using Dataview Web Parts, jQuery, and a roll of duct tape. Just because you know how to write code in Visual Studio does not mean you are a SharePoint Developer. What’s the conclusion here? How do we define ‘it’ and what ‘it’ is called? Fortunately, this is MY blog. I don’t have to give answers, I can stir the pot, laugh and leave you to ponder what it means! There is obviously no right or wrong answer here (unless you disagree with me,then you are flat out wrong). Anyway, there are many opinions.  Here’s mine.  If you put SharePoint Developer on your resume make sure to clearly specify HOW you develop in SharePoint and what tools you use. If we must label these gurus of jQuery and SPD, how about “SharePoint Client Developer” or “SharePoint Front End Developer”? Just throwing out an idea. Whatever we call them, to say they are not developers is short-sighted, arrogant, and unfair. Of course, then we need to figure out what to call all those other SharePoint development types.  Twitter Conversation @next_connect: RT @mrackley: Can someone be considered a SharePoint Developer if all they know how to do is work in SPD? | I say no.... @mikegil:  @mrackley re: yr Developer question: SPD expert <> SP Developer. Can be "sous-developer," though. #SharePoint #SPD @WonderLaura:  Rt @mrackley Can someone be considered a SharePoint Dev if all they know how to do is work in SPD? -- My opinion is that devs write code. @exnav29:  Rt @mrackley Can someone be considered a SharePoint Dev if all they know how to do is work in SPD? => I think devs would use VS as well @ssKevin:  @WonderLaura @mrackley does that mean strictly vb and c# when it comes to #SharePoint ? @jimmywim:  @exnav29 @mrackley nah, I'd say they were a power user. Devs know their way around the 12 hive ;) @sympmarc:  RT @mrackley: Can someone be considered a SharePoint Developer if all they know how to do is work in SPD? -> Fighting words. @sympmarc:  @next_connect @mrackley Besides, we prefer to be called "hacks". ;+) @next_connect:  @sympmarc The important thing is that you don't have to develop code to solve problems and create solutions. @mrackley @mrackley:  @sympmarc @next_connect not tryin to pick fight.. just try and find consensus on definition @usher:  @mrackley I'd still argue that you have a DevLite title that's out there for the collaboration engineers (@sympmarc @next_connect) @next_connect: @usher I agree. I've called it Light Dev/ Configuration before. @sympmarc @mrackley @usher:  @next_connect I like DevLite, low calorie but still same great taste :) @mrackley @sympmarc @mrackley:  @next_connect @usher @sympmarc I don't think there's any "lite" to someone who can bend jQuery and XSLT to their will. @usher:  @mrackley okay, so would you refer to someone that writes user controls and assemblies something different (@next_connect @sympmarc) @usher:  @mrackley when looking for a developer that can write .net code, it's a bit different than an XSLT/jQuery designer. @sympmarc @next_connect @jimmywim:  @mrackley @sympmarc @next_connect I reckon a "dev" does managed code and works in the 12 hive @sympmarc:  @jimmywim @mrackley @next_connect We had a similar debate a few days ago @toddbleeker et al @sympmarc:  @sympmarc @jimmywim @mrackley @next_connect @toddbleeker @stevenmfowler More abt my Middle Tier term, but still connected.

• What is controlling the desktop display?

  - by Bart Silverstrim

  I have two Ubuntu systems and in the course of changing configurations something has become muddled. I have disabled Unity in favor of gnome shell, the older style display of the desktop. Then I installed xfce 4. Seemed everything would be working okay, and for the most part it does. Except I noticed that on one system there's something else controlling settings. On one, if I right click the desktop, I get the menu with the options: open in new window create launcher... create url link... create folder... create from template -> open terminal here paste desktop settings... properties... applications -> On system two, right clicking brings up the menu: Create new folder Create new document -> organize desktop by name keep aligned paste Change Desktop Background Additionally, even though I set the background with the xfce settings manager, on system two that background will appear for a few seconds before it's replaced by something that looks like a background from Ubuntu's original desktop. And it's being controlled by what comes up with the "change desktop background" when right clicking, which isn't the xfce settings manager. On the first system, that right click does bring up the xfce settings tool. In short, something is controlling/overriding the xfce settings on machine two, but I can't find what file or configuration tool is doing it. How can I get system two to behave as system one, giving control of settings and configuration of X to XFCE's tools?

• CoffeeScript Test Framework

  - by Liam McLennan

  Tonight the Brisbane Alt.NET group is doing a coding dojo. I am hoping to talk someone into pairing with me to solve the kata in CoffeeScript. CoffeeScript is an awesome language, half javascript, half ruby, that compiles to javascript. To assist with tonight’s dojo I wrote the following micro test framework for CoffeeScript: <html> <body> <div> <h2>Test Results:</h2> <p class='results' /> </div> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script type="text/coffeescript"> # super simple test framework test: { write: (s) -> $('.results').append(s + '<br/>') assert: (b, message...) -> test.write(if b then "pass" else "fail: " + message) tests: [] exec: () -> for t in test.tests test.write("<br/><b>$t.name</b>") t.func() } # add some tests test.tests.push { name: "First Test" func: () -> test.assert(true) } test.tests.push { name: "Another Test" func: () -> test.assert(false, "You loose") } # run them test.exec(test.tests) </script> <script type="text/javascript" src="coffee-script.js"></script> </body> </html> It’s not the prettiest, but as far as I know it is the only CoffeeScript test framework in existence. Of course, I could just use one of the javascript test frameworks but that would be no fun. To get this example to run you need the coffeescript compiler in the same directory as the page.

• Go Big or Go Home

  - by Justin Kestelyn

  The Oracle Develop conference (#oracledevelop10), being co-located for the first time ever with JavaOne in San Francisco, is guaranteed to be the ultimate rush for developers this year. Where else can you go to learn about, interact with, and meet fellow devotees of the entire Oracle Development stack (welcome, Oracle Solaris)? This will also be the first time that the community space traditionally located at Oracle OpenWorld - and hosted by Oracle Technology Network, as always - will be present at the "developer" conference during this busy week. So, Oracle OpenWorld's loss is Oracle Develop's gain. And what a community space it will be: nearly 4,000 square feet for meeting space, contests and give-aways, consumption of various beverages, special speakers (Oracle ACEs among them, no doubt), and video-casting. The entire Oracle Technology Network crew will be on hand to "facilitate" your experience, of course. Even better, you can rub shoulders and share war stories with attendees from that "other" conference, JavaOne. (You have access to both conferences as a single package, so you may be having a conversation with yourself.) We call the whole enchilada "The Zone". As time goes on, we'll bring you more news about the activities described above, as well as OTN Night (which proves to be more raucous than ever), technical sessions and keynotes not to be missed, the unconference/open sessions, things to do at night, and more. In the meantime, stay in touch with us via Twitter or Oracle Mix.

• SQL SERVER – A Funny Cartoon on Index

  - by pinaldave

  Performance Tuning has been my favorite subject and I have done it for many years now. Today I will list one of the most common conversation about Index I have heard in my life. Every single time, I am at consultation for performance tuning I hear following conversation among various team members. I want to ask you, does this kind of conversation happens in your organization? Any way, If you think Index solves all of your performance problem I think it is not true. There are many other reason one has to consider along with Indexes. For example I consider following various topic one need to understand for performance tuning. ?Logical Query Processing ?Efficient Join Techniques ?Query Tuning Considerations ?Avoiding Common Performance Tuning Issues Statistics and Best Practices ?TempDB Tuning ?Hardware Planning ?Understanding Query Processor ?Using SQL Server 2005 and 2008 Updated Feature Sets ?CPU, Memory, I/O Bottleneck Index Tuning (of course) ?Many more… Well, I have written this blog thinking I will keep this blog post a bit easy and not load up. I will in future discuss about other performance tuning concepts. Let me know what do you think about the cartoon I made.

• What happened to Alan Cooper's Unified File Model?

  - by PAUL Mansour

  For a long time Alan Cooper (in the 3 versions of his book "About Face") has been promoting a "unified file model" to, among other things, dispense with what he calls the most idiotic message box ever invented - the one the pops up when hit the close button on an app or form saying "Do you want to discard your changes?" I like the idea and his arguments, but also have the knee-jerk reaction against it that most seasoned programmers and users have. While Cooper's book seems quite popular and respected, there is remarkably little discussion of this particular issue on the Web that I can find. Petter Hesselberg, the author of "Programming Industrial Strength Windows" mentions it but that seems about it. I have an opportunity to implement this in the (desktop) project I am working on, but face resistance by customers and co-workers, who are of course familiar with the MS Word and Excel way of doing things. I'm in a position to override their objections, but am not sure if I should. My questions are: Are there any good discussions of this that I have failed to find? Is anyone doing this in their apps? Is it a good idea that it is unfortunately not practical to implement until, say, Microsoft does it?

• Java, the Cloud, and Oracle at QCon San Francisco 2011

  - by Bob Rhubart

  If you're part of the lucky bunch attending this week's sold-out QCon San Francisco conference at Westin San Francisco Market Street, I'd like to bring several sessions to your attention. On Wednesday Nov 16, Alex Buckley, specification lead for the Java Language and the Java Virtual Machine at Oracle, will present Java 7 and 8: Where We've Been, Where We're Going, part of the Why is Java still sexy? track. The session begins at 10:35 a.m. in the Olympic room. On Thursday Nov 17, Tyler Jewell, VP Product Management for Oracle's Platform as a Service, will participate in the Performance and Scalability Panel moderated by InfoQ founder and QCon SF Program Committee Member Floyd Marinescu. That panel, part of the Performance and Scalability Solutions track, begins at 10:35 a.m. in the Olympic room. Following that panel discussion, Tyler will fly solo with a presentation on Java EE 7: Developing for the Cloud, also part of the Performance and Scalability Solutions track. That session kicks off at 12:05 p.m., also in the Olympic room. On Friday Nov 18 Tyler will jump tracks, so to speak, when he presents The Architecture of Oracle's Public Cloud, part of the Architecture Case Studies: Cloud track. That session begins at 4:50 p.m. in the Stanford room. Of course, QCon also offers ample meet-and-greet opportunities. One such opportunity happens in the hospitality suite hosted by the Java Community Process Executive Committee. That shindig gets in gear at 5:50 pm on Thursday. Throughout the QCon San Francisco conference, members of the OTN team (including your's truly) and members of the Oracle Fusion Middleware team will be on hand at the OTN booth in the conference lobby. Stop by to say hello, score some swag, and catch a demo or two.

• Daylight Saving Time Visualized

  - by Jason Fitzpatrick

  When you map out the Daylight Saving Time adjusted sunrise and sunset times over the course of the year, an interesting pattern emerges. Chart designer Germanium writes: I tried to come up with the reason for the daylight saving time change by just looking at the data for sunset and sunrise times. The figure represents sunset and sunrise times thought the year. It shows that the daylight saving time change marked by the lines (DLS) is keeping the sunrise time pretty much constant throughout the whole year, while making the sunset time change a lot. The spread of sunrise times as measured by the standard deviation is 42 minutes, which means that the sunrise time changes within that range the whole year, while the standard deviation for the sunset times is 1:30 hours. Whatever the argument for doing this is, it’s pretty clear that reason is to keep the sunrise time constant. You can read more about the controversial history of Daylight Saving Time here.

• Ubuntu eats itself after I followed updater instruction

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I (and this is from noob memory) sudo apt-get install -f. I did this and typed in the confirmation phrase and watched apt-get systematically remove every component of linux, both the stuff I installed and the core ubuntu packages. I could only assume at this stage that this was for a fresh install but of course, I know better now. There's much complaint about Windows, but I've never met with advice from Microsoft tools to wipe out the operating system because of a couple of missing .dlls. So what gives? This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. I'm tempted, but I have hopes of recovering the data that I had enough misguided faith to trust to the linux ext4 partition. I've tried pen driving back into it with a 32 bit iso but I'm simply informed that ubuntu is running in low graphics mode and get to watch the dots cycle indefinitely. EDIT: Thanks for the advice vis positive request. I've got onto the machine with a 64 bit stick and can see the file structure left behind by the installation. My first instinct was to run install from the stick but it did not seem to offer a recovery option. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings. I'm particularly worried about losing email from evolution - the rest I could probably lash back together. I would also be interested how this disaster came about. I see people in the know recommending this same procedure in similar circumstances. Thanks for your attention, Tony Martin

• Glenn Fiedler's fixed timestep with fake threads

  - by kaoD

  I've implemented Glenn Fiedler's Fix Your Timestep! quite a few times in single-threaded games. Now I'm facing a different situation: I'm trying to do this in JavaScript. I know JS is single-threaded, but I plan on using requestAnimationFrame for the rendering part. This leaves me with two independent fake threads: simulation and rendering (I suppose requestAnimationFrame isn't really threaded, is it? I don't think so, it would BREAK JS.) Timing in these threads is independent too: dt for simulation and render is not the same. If I'm not mistaken, simulation should be up to Fiedler's while loop end. After the while loop, accumulator < dt so I'm left with some unspent time (dt) in the simulation thread. The problem comes in the draw/interpolation phase: const double alpha = accumulator / dt; State state = currentState*alpha + previousState * ( 1.0 - alpha ); render( state ); In my render callback, I have the current timestamp to which I can subtract the last-simulated-in-physics-timestamp to have a dt for the current frame. Should I just forget about this dt and draw using the physics thread's dt? It seems weird, since, well, I want to interpolate for the unspent time between simulation and render too, right? Of course, I want simulation and rendering to be completely independent, but I can't get around the fact that in Glenn's implementation the renderer produces time and the simulation consumes it in discrete dt sized chunks. A similar question was asked in Semi Fixed-timestep ported to javascript but the question doesn't really get to the point, and answers there point to removing physics from the render thread (which is what I'm trying to do) or just keeping physics in the render callback too (which is what I'm trying to avoid.)

• List SQL Server Instances using the Registry

  - by BuckWoody

  I read this interesting article on using PowerShell and the registry, and thought I would modify his information a bit to list the SQL Server Instances on a box. The interesting thing about listing instances this was is that you can touch remote machines, find the instances when they are off and so on. Anyway, here’s the scriptlet I used to find the Instances on my system: $MachineName = '.' $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName) $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" ) $regkey.GetValueNames() You can read more of his article to find out the reason for the remote registry call and so forth – there are also security implications here for being able to read the registry. 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. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people.

• What is the best way to evaluate new programmers?

  - by Rafael

  What is the best way to evaluate the best candidates to get a new job (talking merely in terms of programming skills)? In my company we have had a lot of bad experiences with people who have good grades but do not have real programming skills. Their skills are merely like code monkeys, without the ability to analyze the problems and find solutions. More things that I have to note: The education system in my country sucks--really sucks. The people that are good in this kind of job are good because they have talent for it or really try to learn on their own. The university / graduate /post-grad degree doesn't mean necessarily that you know exactly how to do the things. Certifications also mean nothing here because the people in charge of the certification course also don't have skills (or are in low paying jobs). We need really to get the good candidates that are flexible and don't have mechanical thinking (because this type of people by experience have a low performance). We are in a government institution and the people that are candidates don't necessarily come from outside, but we have the possibility to accept or not any candidates until we find the correct one. I hope I'm not sounding too aggressive in my question; and BTW I'm a programmer myself. edit: I figured out that asked something really complex here. I will un-toggle "the correct answer" only to let the discussion going fluent, without any bias.

• Welcome to the Weblog on Oracle ADF Mobile!

  - by joe.huang

  Welcome to ADF Mobile team's weblog.  My name is Joe Huang - I am the product manager for ADF Mobile.  Oracle ADF Mobile is a part of Oracle's Application Development Framework (ADF) that support the development of enterprise/business applications that run on mobile devices.  The development tool for this framework is of course Oracle JDeveloper.  As some of you may know, we currently support the development of mobile browser-based application - this part of product is called ADF Mobile Browser.  Additionally, we are close to release a technology preview of ADF Mobile Client, which supports development of on-device, disconnect capable mobile applications.  What's truly unique about ADF Mobile development process is that it's a very visual and declarative experience, while still allow power Java developers to completely extend the framework to their liking.  The framework also provides a rich set of services needed by an enterprise-grade mobile application - these services would literally take years to implement if they are to be built from the ground up.  However, by using JDeveloper and ADF Mobile, you get the entire framework at your service!In the coming entries, the ADF Mobile product development team will publish any news, best practices, our observation on mobile technology trends, or just our experiences in playing with "gadgets".  Be sure to check back on this page!Sincerely,Joe HuangOracle

• Complex knowledge management system with CRM..written internally

  - by JonH

  We've all heard of salesforce and sugarcrm and the likes of systems like this. Unfortunately at my workplace we have been asked to write a similiar system (rather then license or purchase). Basically the database is fairly large. Think of modules such as: Corporate groups, customers, programs, projects, sub projects, and issue management. In simple terms a corporate group has one to many customers. A program has one or more projects. A project has one or more sub projects. And an issue can be created on many sub projects. Of course the system is a bit more complex but instead of listing every single module I think its best to keep it simple. In any event, the system in its current state has only two resources to be working on it (basically we have to do it all: CSS, database, jquery, asp.net and C#). We've started off well by defining the UI master and footer pages that way we can reuse those across all of our pages. Now comes the hard part. The system will have about 4k end users with say 5-10% being concurrent users. We are wondering if it makes sense to cache our database data (For say 5-10 minutes) rather then continously hit our database. The reason being is some of these pages may have 5-10 search filters associated with the page. Imagine every time a selection is made from a search box how many database hits. Also some of these search fields cascade so selecting for instance an initial drop down may cascade several drop down boxes under them. Is it wrong to cache because I am not finding too many articles on whether it is a good idea or not. Remember the system is similiar to say a CRM system where we manage our various customers, projects, sub projects, issues, etc.

• Advantages of using pure JavaScript over JQuery

  - by Shivan Dragon

  What are the advantages of using Javascript-only versus using JQuery-only? I have limited experience with JavaScript and JQuery coding. I've added bits and snippets of each to HTML pages but I've mostly coded server-side stuff in other languages. I've noticed that while you can theoretically do the same things using either of the two approaches (and of course you can even mix 'em up in the same project) there seems to be a tendency to always start using JQuery from the very beginning no-matter what the project demands are. So I'm simply wondering, are there any punctual benefits to not use JQuery-only but instead to just use plain old JavaScript? I know this looks like a non-question because it can be said about it that "there's no definite answer" or "it can be debated for ever", but I'm actually hoping for punctual answers such as "You can do this in one approach and you cannot do it with the other". ==EDIT== As per scrwtp's comment, I'm not referring just to the DOM Handling part. My question is rather: JQuery is a library. For Javascript. What I find strange about this library as opposed to other libraries for other languages is that in JQyery's case it seems to be designed to be able to use it exclusively and not need to touch Javascript directly. This is as opposed to let's say Hibernate and SQL, where even though the library (or rather framework in this case, but I think the analogy still applies) takes the handle on A LOT of aspects, you still get to use SQL when using it, at least for some fringe cases. However in JQuery & Javascript case, you could do anything you do with Javascript using only JQuery (or at least that's how it seems to me).

• Unleash AutoVue on Your Unmanaged Data

  - by [email protected]

  Over the years, I've spoken to hundreds of customers who use AutoVue to collaborate on their "managed" data stored in content management systems, product lifecycle management systems, etc. via our many integrations. Through these conversations I've also learned a harsh reality - we will never fully move away from unmanaged data (desktops, file servers, emails, etc). If you use AutoVue today you already know that even if your primary use is viewing content stored in a content management system, you can still open files stored locally on your computer. But did you know that AutoVue actually has - built-in - a great solution for viewing, printing and redlining your data stored on file servers? Using the 'Server protocol' you can point AutoVue directly to a top-level location on any networked file server and provide your users with a link or shortcut to access an interface similar to the sample page shown below. Many customers link to pages just like this one from their internal company intranets. Through this webpage, users can easily search and browse through file server data with a 'click-and-view' interface to find the specific image, document, drawing or model they're looking for. Any markups created on a document will be accessible to everyone else viewing that document and of course real-time collaboration is supported as well. Customers on maintenance can consult the AutoVue Admin guide or My Oracle Support Doc ID 753018.1 for an introduction to the server protocol. Contact your local AutoVue Solutions Consultant for help setting up the sample shown above.

• Mission critical embedded language

  - by Moe

  Maybe the question sounds a bit strange, so i'll explain a the background a little bit. Currently i'm working on a project at y university, which will be a complete on-board software for an satellite. The system is programmed in c++ on top of a real-time operating system. However, some subsystems like the attitude control system and the fault detection and a space simulation are currently only implemented in Matlab/Simulink, to prototype the algorithms efficiently. After their verification, they will be translated into c++. The complete on-board software grew very complex, and only a handful people know the whole system. Furthermore, many of the students haven't program in c++ yet and the manual memory management of c++ makes it even more difficult to write mission critical software. Of course the main system has to be implemented in c++, but i asked myself if it's maybe possible to use an embedded language to implement the subsystem which are currently written in Matlab. This embedded language should feature: static/strong typing and compiler checks to minimize runtime errors small memory usage, and relative fast runtime attitude control algorithms are mainly numerical computations, so a good numeric support would be nice maybe some sort of functional programming feature, matlab/simulink encourage you to use it too I googled a bit, but only found Lua. It looks nice, but i would not use it in mission critical software. Have you ever encountered a situation like this, or do you know any language, which could satisfies the conditions? EDIT: To clarify some things: embedded means it should be able to embed the language into the existing c++ environment. So no compiled languages like Ada or Haskell ;)

• OpenGL texture on sphere

  - by Cilenco

  I want to create a rolling, textured ball in OpenGL ES 1.0 for Android. With this function I can create a sphere: public Ball(GL10 gl, float radius) { ByteBuffer bb = ByteBuffer.allocateDirect(40000); bb.order(ByteOrder.nativeOrder()); sphereVertex = bb.asFloatBuffer(); points = build(); } private int build() { double dTheta = STEP * Math.PI / 180; double dPhi = dTheta; int points = 0; for(double phi = -(Math.PI/2); phi <= Math.PI/2; phi+=dPhi) { for(double theta = 0.0; theta <= (Math.PI * 2); theta+=dTheta) { sphereVertex.put((float) (raduis * Math.sin(phi) * Math.cos(theta))); sphereVertex.put((float) (raduis * Math.sin(phi) * Math.sin(theta))); sphereVertex.put((float) (raduis * Math.cos(phi))); points++; } } sphereVertex.position(0); return points; } public void draw() { texture.bind(); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, sphereVertex); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); } My problem now is that I want to use this texture for the sphere but then only a black ball is created (of course because the top right corner s black). I use this texture coordinates because I want to use the whole texture: 0|0 0|1 1|1 1|0 That's what I learned from texturing a triangle. Is that incorrect if I want to use it with a sphere? What do I have to do to use the texture correctly?

• Major Google not follow increase since introducing 301 to site

  - by jakob

  Recently we implemented Varnish in front of our web nodes so that the backend would get some rest from time to time. Since varnish is case sensitive and our app was not we implemented a 301 in varnish to redirect to small case. Example: You search for PlumBer StockHOLM you will get a 301 redirect to plumber stockholm and then plumber stockholm will be cached. This worked as a charm, but when checking the Google webmaster tools we suddenly got a crazy amount of Status - Not able to follow errors. As you can see in the image below: This of course stirred up some panic and I started to read up on the documentation once again. If I pressed on one of the links I got to the help section where i found this: Well this is strange, but as the day progressed more and more errors were thrown by Google. We took the decision to make varnish return 200 instead of the 301. Now when testing the links that appears in the Not able to follow section I get a 200 back. I have tested with Chrome, curl and lynx reader and everything looks ok but the amount of errors are still increasing. What is a little bit comforting is that the links that appears in the Not able to follow section are dated before the 200 change in varnish. Why do I get these errors and why do they keep increasing? Did google release something new on October 31? Maybe I do not understand the docs correctly?

• Progress 4GL and DB to Oracle and cloud

  - by llaszews

  Getting from client/server based 4GLs and databases where the 4GL is tightly linked to the database to Oracle and the cloud is not easy. The least risky and expensive option (in the short term) is to use the Progress OpenEdge DataServer for Oracle: Progress OpenEdge DataServer This eliminates the need to have to migrate the Progress 4GL to Java/J2EE. The database can be migrated using SQLWays Ispirer: Ispirer SQLWays ProgressDB migrations tool The Progress 4GL can remain as is. In order to get the application on the cloud there are a few approaches: 1. VDI - Virtual Desktop is a way to put all of the users desktop in a centralized environment off the desktop. This is great in cases where it is just not one client/server application that the user needs access too. In many cases, users will utilize MS Access, MS Excel, Crystal Reports and other tools to get at the Progress DB and other centralized databases. Vmware's acquistion of Wanova shows how VDI is growing in usage. Citrix is the 800 pound gorilla in the VDI space with Citrix WinFrame (now called XenDesktop). Oracle offers a VDI solution that Oracle picked up when it acquired Sun. 2. Hypervisor Server Virtualization - Of course you can place applications written in client/server languages like Progress 4GL buy using server virtualization from Oracle, VMWare, Microsoft, Citrix and others. 3. Microsoft Remote Desktop Services (aka: Terminal Services Client) The entire idea is to eliminate all the client/server desktop devices and connections which require desktop software and database drivers. A solution to removing database drivers from the desktop is to use DataDirect SQLLink

• Create Windows Bootloader/Boot into Windows from Ubuntu

  - by Kincaid

  I have computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I have decided I wanted to remove Ubuntu, as I hardly used it. As a stupid mistake, I deleted the Ubuntu partition before changing the bootloader to replace Grub. Whenever I know boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better. I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader solutions. I have looked into using boot-repair to solve the problem using the instructions here, although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Is there any options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? In the end, I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine -- I can use EasyBCD from there. Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows. Any help would be greatly appreciated.

• Stupid Geek Tricks: Change Your IP Address From the Command Line in Linux

  - by Taylor Gibb

  Almost everybody can figure out how to change their IP address using an interface, but did you know you can set your network card’s IP address using a simple command from the command line? Changing Your IP From the Command Line in Linux Note: This will work on all Debian based Linux Distro’s. To get started type ifconfig into the terminal and hit enter, take note of the name of the interface that you want to change the settings for. To change the settings, you also use the ifconfig command, this time with a few parameters: sudo ifconfig eth0   192.168.0.1 netmask 255.255.255.0 That’s about all all you need to do to change your IP, of course the above command assumes a few things: The interface that you want to change the IP for is eth0 The IP you want to give the interface is 192.168.0.1 The Subnet Mask you want to set for the interface is 255.255.255.0 If you run ifconfig again you will see that your interface has now taken on the new settings you assigned to it. If you wondering how to change the Default Gateway, you can use the route command. sudo route add default gw 192.168.0.253 eth0 Will set your Default Gateway on the eth0 interface to 192.168.0.253. To see your new setting, you will need to display the routing table. route -n That’s all there is to it.

• Changing the BizTalk message output file name

  - by Bill Osuch

  By default, BizTalk creates the filename of the message dropped to a send port as %MessageID%, which is the unique identifier (GUID) of the message. What if you want to create your own filename? To start, create a simple schema, and a basic orchestration that will receive the message and send it right back out, like this: If you deploy this and wire up the ports, you can drop an xml file into your receive port and have it come out at your send port named something like {7A63CAF8-317B-49D5-871F-9FD57910C3A0}.xml. Now, we'll create a new message with a custom filename. First, create a new orchestration variable called NewFileName, of the type System.String. Next, create a second message using the same schema as the message you're receiving in the Receive shape. Now, drag a Construct Message shape to the orchestration. In the shape's properties, set Messages Constructed to be the new message you just created. Double click the Message Assignment shape (inside the Construct shape...) and paste in the following code: Message_2 = Message_1;   NewFileName = Message_1(FILE.ReceivedFileName); NewFileName = NewFileName.Replace(".xml","_"); NewFileName = NewFileName + "output_" + System.DateTime.Now.Year.ToString() + "-" + System.DateTime.Now.Month.ToString();   Message_2(FILE.ReceivedFileName) = NewFileName; Here we make a copy of the received message, get it's original file name (ReceivedFileName), replace its extension with an underscore, and date-stamp it. Finally, add a Send shape and a Port to the surface, and configure them to send the message you just created. You should wind up with an orchestration like this: Deploy it, and create a new send port. It should be just about identical to the first send port, except this time the file name will be "%SourceFileName%.xml" (without the quotes of course). Fire up the application, drop in a test file, and you should now get both the xml file named with a GUID, and a second file named something along the lines of "MySchemaTestFile_output_2011-6.xml".

• Ambiguous in the namespace problem

  - by Agha Usman Ahmed

  From the last few days, I was ignoring an error that keep coming at the compile time. I spent some two hours on it before but didn’t get it work. The error is quit confusing and of course difficult to manage. 'ApplicationSettingsBase' is ambiguous in the namespace 'System.Configuration' 'MailMessage' is ambiguous in the namespace 'System.Net.Mail' And there are couple of other similar errors that is pointing to some ambiguous references in my project.  The confusing part is that the MailMessage object throws similar error when you are importing the old and new email namespace. For example, Imports System.Web.Mail Imports System.Net.Mail So if you are only encountering ambiguous problem in MailMessage object. It is more possible that you have define both the namespaces in your code behind which is actually confusing the compiler about your referencing object. The quick solve for this problem is that remove Imports System.Web.Mail and it should work smooth. But with me, I never used the old asp.net mail namespace in my project. Then I start looking at my references and luckily I found the problem there. Follow the steps below to investigate the issue 1. Go to your project 2. Then references 3. Right click on “System” and see properties. it should point to the following path x:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll Where x is name of your operating system directory. This was the problem with my project. I had my operating system install on “D” drive and some how it is pointing to “C” drive which is the root cause of this problem. After that I verify all my references and found 5 –6 assemblies that are pointing to wrong path and get it worked. Also note, the problem can occur in any type of project either it is website , web application etc.
