• Becoming a Certified Information Professional

  - by Lance Shaw

  Yesterday, we participated with AIIM in a webinar about the Certified Information Professional (CIP) program that they are now offering.  The interest level is very high in the program, as evidenced by the high turnout at the event. You might be asking yourself, what does the Oracle WebCenter team care about an AIIM certification program? Well, we sponsored this program because we consistently find that the more educated our customers and prospects are, the more value they are going to get out of the technology we provide.  As an ECM vendor, we provide plenty of WebCenter product training and certifications to help you make the most of WebCenter technology. While these are essential and valuable, technologists that also have an operational command of the business and the various impacts that the flow of information can have are even more valuable to an organization. Thinking about the management of content and information and its effect on business process can have wide-ranging benefits, not only to your company but to your personal bottom line.  And let's be honest, a customer who is looking holistically at how content is managed is going to see more opportunities to leverage that content and in many cases, this will motivate the purchase of additional product licenses.   Now if you are regretting the fact that you missed the webinar yesterday, never fear!  It is now available for playback and you can view it at your convenience by visiting the AIIM website. We hope you find it informative and that you can personally profit from being able to showcase your certification as an Information Professional. Additionally, we hope it will help you identify additional opportunities to leverage Oracle WebCenter in order to further reduce your operational costs and drive your business forward.

• Solaris at LISA 2011

  - by dminer

  As is our custom, the Solaris team will be out in force at the USENIX LISA conference; this year it's in Boston so it's sort of a home game for me for a change.  The big event we'll have is Tuesday, December 6, the Oracle Solaris 11 Summit Day.  We'll be covering deployment, ZFS, Networking, Virtualization, Security, Clustering, and how Oracle apps run best on Solaris 11.  We've done this the past couple of years and it's always a very full day.On Wednesday, December 7, we've got a couple of BOF sessions scheduled back-to-back.  At 7:30 we'll have the ever-popular engineering panel, with all of us who are speaking at Tuesday's summit day there for a free-flowing discussion of all things Solaris.  Following that, Bart & I are hosting a second BOF at 9:30 to talk more about deployment for clouds and traditional data centers.Also, on Wednesday and Thursday we'll have a booth at the exhibition where there'll be demos and just a general chance to talk with various Solaris staff from engineering and product management.The conference program looks great and I look forward to seeing you there!

• 48hrs in Cambridge.

  - by Fatherjack

  In just over 2 weeks something pretty big in the SQL Server Community in the UK is taking place. We are going to witness the first SQL Saturday on these shores. The event is running in Cambridge, the home of the SQL Cambs user group and the chapter leader there (Mark Broadbent) is the lead on the SQL Saturday event too. Mark and his team are making final preparations and looking forward to this event getting started with the Pre-Con day on Friday 7th Sept. They have 3 great sessions from Buck Woody, Jen Stirrup and Mark Rasmussen for those lucky enough to be able to attend on the Friday. There are over 30 speakers providing 4 tracks of sessions on the Saturday so there will be plenty to interest and inform anyone working with SQL Server, take a look at all the sessions on the schedule. In addition to all of this you will be able to spend some quality time talking to all the other attendees, sponsors and PASS representatives to make the most of your time there.

• How to get a Toshiba L505 to boot USB or CD

  - by ShroudedCloud

  OK, have a Toshiba L505 (not sure of the extended model number) that got a virus on Windows and will no longer will boot into that, so I'm trying to revive it with Ubuntu. Problem is, when I tell it to boot into a USB image of 12.04 32- or 64-bit, 13.04 64-bit, or elementary Luna 32-bit, it gives me some screen with a copyright from 2000 for Intel, invariably spits out a "media not recognized" type of error and then says PXE-ROM exiting. Well, that's annoying. So I went in with a CD (12.04 x86_64 having tried 32-bit in the past as well). Boot menu, select, starts running. Seeing the loading screen for Ubuntu, going well... until it's not. Again, invariably, it fails. The CD drive will cease spinning at around the same time each time and then the laptop will stop doing everything altogether (at least, everything spins down and it goes quiet). As far as I can tell, it's not to do with what function is being loaded from the CD at the time (because that bit is variable). I'd love to be able to boot from USB (since it will be all but required going forward), but getting the CD to work would be wondrous too. Anyone have any ideas of where I can go from here to try to fix this? My friends and I have turned up nothing.

• When to use PHP or ASP.NET? [closed]

  - by loyalpenguin

  I have worked extensively in developing web applications using PHP and ASP.NET, but one of the questions that I'm constantly asked by customers is whether to move forward with a php website or an asp.net website. So naturally the first thing that comes to mind is to answer the question like this: PHP is open-source and ASP.NET is from Microsoft. Usually after something like that is said the customer has a blank look on there face. Apparently the fact that one is open source and the other isn't doesn't really faze them. And for good reason, because when I first heard it, it really doesn't tell me much. I know from working with both that each have their + and - when it comes to developing websites. NOTE: THIS QUESTION IS NOT TO QUESTION WHICH IS BETTER TO DEVELOP WITH. THIS QUESTION IS INTENDED TO BE OBJECTIVE. My question is what are differences between ASP.NET and PHP as far as Features Security Extendability Frameworks Average Development Time And when one is generally used over the other for certain types of projects. I am trying to compile a list of facts to be able to compare with the customer what developement platform is better for there particular project. I have done a simple search on google and a ton of articles come up, but the problem is the majority are usually biased towards PHP or ASP.NET. Also if you can maybe provide examples from experience when one technology was more preferable than the other that would be awesome.

• Antenna Aligner Part 8: It's Alive!!!

  - by Chris George

  Finally the day has come, Antenna Aligner v1.0.1 has been uploaded to the AppStore and . "Waiting for review" .. . fast forward 7 days and much checking of emails later WOO HOO! Now what? So I set my facebook page to go live  https://www.facebook.com/AntennaAligner, and started by sending messages to my mates that have iphones! Amazingly a few of them bought it! Similarly some of my colleagues were also kind enough to support me and downloaded it too! Unfortunately the only way I knew they had bought is was from them telling me, as the iTunes connect data is only updated daily at about midday GMT. This is a shame, surely they could provide more granular updates throughout the day? Although I suppose once an app has been out in the wild for a while, daily updates are enough. It would, however, be nice to get a ping when you make your first sale! I would have expected more feedback on my facebook page as well, maybe I'm just expecting too much, or perhaps I've configured the page wrong. The new facebook timeline layout is just confusing, and I'm not sure it's all public, I'll check that! So please take a look and see what you think! I would love to get some more feedback/reviews/suggestions... Oh and watch out for the Android version coming soon!

• New Responsibilities

  - by Robert May

  With the start of the new year, I’m starting new responsibilities at Veracity. One responsibility that is staying constant is my love and evangelism of Agile.  In fact, I’ll be spending more time ensuring that all Veracity teams are performing agile, Scrum specifically, in a consistent manner so that all of our clients and consultants have a similar experience. Imagine, if you will, working for a consulting company on a project.  On that project, the project management style is Waterfall in iterations.  Now you move to another project and in that project, you’re doing real Scrum, but in both cases, you were told that what you were doing was Scrum.  Rather confusing.  I’ve found, however, that this happens on many teams and many projects.  Most companies simply aren’t disciplined enough to do Scrum.  Some think that being Agile means not being disciplined.  The opposite is true! So, my goals for Veracity are to make sure that all of our consultants have a consistent feel for Scrum and what it is and how it works and then to make sure that on the projects they’re assigned to, Scrum is appropriately applied for their situation.  This will help keep them happier, but also make switching to other projects easier and more consistent.  If we aren’t doing the project management on the project, we’ll help them know what good Agile practices should look like so that they can give good advice to the client, and so that if they move to another project, they have a consistent feel. I’m really looking forward to these new duties. Technorati Tags: Agile,Scrum

• Adding 2D vector movement with rotation applied

  - by Michael Zehnich

  I am trying to apply a slight sine wave movement to objects that float around the screen to make them a little more interesting. I would like to apply this to the objects so that they oscillate from side to side, not front to back (so the oscillation does not affect their forward velocity). After reading various threads and tutorials, I have come to the conclusion that I need to create and add vectors, but I simply cannot come up with a solution that works. This is where I'm at right now, in the object's update method (updated based on comments): Vector2 oldPosition = new Vector2(spritePos.X, spritePos.Y); //note: newPosition is initially set in the constructor to spritePos.x/y Vector2 direction = newPosition - oldPosition; Vector2 perpendicular = new Vector2(direction.Y, -direction.X); perpendicular.Normalize(); sinePosAng += 0.1f; perpendicular.X += 2.5f * (float)Math.Sin(sinePosAng); spritePos.X += velocity * (float)Math.Cos(radians); spritePos.Y += velocity * (float)Math.Sin(radians); spritePos += perpendicular; newPosition = spritePos;

• Sitecore Item Web API and Json.Net Test Drive (Part II –Strongly Typed)

  - by jonel

  In the earlier post I did related to this topic, I have talked about using Json.Net to consume the result of Sitecore Item Web API. In that post, I have used the keyword dynamic to express my intention of consuming the returned json of the API. In this article, I will create some useful classes to write our implementation of consuming the API using strongly-typed. We will start of with the Record class which will hold the top most elements the API will present us. Pretty straight forward class. It has 2 properties to hold the statuscode and the result elements. If you intend to use a different property name in your class from the json property, you can do so by passing a string literal of the json property name to the JsonProperty attribute and name your class property differently. If you look at the earlier post, you will notice that the API returns an array of items that contains all of the Sitecore content item or items and stores them under the result->items array element. To be able to map that array of items, we have to write a collection property and decorate that with the JsonProperty attribute. The JsonItem class is a simple class which will map to the corresponding item property contained in the array. If you notice, these properties are just the basic Sitecore fields. And here’s the main portion of this post that will binds them all together. And here’s the output of this code. In closing, the same result can be achieved using the dynamic keyword or defining classes to map the json propery returned by the Sitecore Item Web API. With a little bit more of coding, you can take advantage of power of strongly-typed solution. Have a good week ahead of you.

• What Should I Do? [closed]

  - by Laxmidi

  What is a reasonable goal in terms of traffic for my Flex 3 site: www.brainpinata.com Since I began a couple of months ago, I've gotten roughly 5500 ad views and 280 ad clicks. And the ad revenue is a whopping $4.80. (I don't use Google Adsense). I advertise my site using Google Adwords to try to build traffic. My budget is $10/day. What should I do? a) Push the marketing. Add a blog. Try to get backlinks, contact blogs, start a Facebook page, tweet, etc. b) Google is only indexing the static content in the SWF. The questions/answers are pulled from a mySQL database. So, Google doesn't index 99% of the content. Should I re-do the site in HTML/Javascript and hard-code the questions for each puzzle? (This would be a challenge as I don't know javascript worth squat.) Or should I hard-code the questions in XML and put them in the Flex app? If I put the questions in an XML file it's roughly 500 KB. Other ideas? c) Should I switch ad networks? (I currently get about 100 visitors a day). My ad network pays so little that if I were to make even $500/month, I would need 550,000 ad views/month, which seems impossible. If I go ahead and switch ad networks, I need to find one that allows iFrames as I've got a Flex website. Which ad networks permit their ads to be shown in iFrames? d) Should I cut and run? I put a lot of work into this project and it would really stink to get nothing out of it. I'm looking for some good advice. Looking forward to your suggestions. Thank you. -Laxmidi

• Using PDO with MVC

  - by mister martin

  I asked this question at stackoverflow and received no response (closed as duplicate with no answer). I'm experimenting with OOP and I have the following basic MVC layout: class Model { // do database stuff } class View { public function load($filename, $data = array()) { if(!empty($data)) { extract($data); } require_once('views/header.php'); require_once("views/$filename"); require_once('views/footer.php'); } } class Controller { public $model; public $view; function __construct() { $this->model = new Model(); $this->view = new View(); // determine what page we're on $page = isset($_GET['view']) ? $_GET['view'] : 'home'; $this->display($page); } public function display($page) { switch($page) { case 'home': $this->view->load('home.php'); break; } } } These classes are brought together in my setup file: // start session session_start(); require_once('Model.php'); require_once('View.php'); require_once('Controller.php'); new Controller(); Now where do I place my database connection code and how do I pass the connection onto the model? try { $db = new PDO('mysql:host='.DB_HOST.';dbname='.DB_DATABASE.'', DB_USERNAME, DB_PASSWORD); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch(PDOException $err) { die($err->getMessage()); } I've read about Dependency Injection, factories and miscellaneous other design patterns talking about keeping SQL out of the model, but it's all over my head using abstract examples. Can someone please just show me a straight-forward practical example?

• Are these company terms good for a programmer or should I move?

  - by o_O

  Here are some of the terms and conditions set forward by my employer. Does these make sense for a job like programming? No freelancing in any way even in your free time outside company work hours (may be okay. May be they wanted their employees to be fully concentrating on their full time job. Also they don't want their employees to do similar work for a competing client. Completely rational in that sense). - So sort of agreed. Any thing you develop like ideas, design, code etc while I'm employed there, makes them the owner of that. Seriously? Don't you think that its bad (for me)? If I'm to develop something in my free time (by cutting down sleep and hard working), outside the company time and resource, is that claim rational? I heard that Steve Wozniak had such a contract while he was working at HP. But that sort of hardware design and also those companies pay well, when compared to the peanuts I get. No other kind of works allowed. Means no open source stuffs. Fully dedicated to being a puppet for the employer, though the working environment is sort of okay. According to my assessment this place would score a 10/12 in Joel's test. So are these terms okay especially considering the fact that I'm underpaid with peanuts?

• What is the best approach for database design with lots of columns?

  - by Pratyush

  I am writing a query based financial application. It lets the user to write complicated equations (much like WHERE part of an SQL query) and find companies matching those criteria. For the above, I currently have more than 500 columns in the database table (each column representing a financial field). Example of Columns are: company_name, sales_annual_00, sales_annual_01, sales_annual_02, sales_annual_03, sales_annual_04, protit_annual_00, profit_annual1...(over 500 such columns). The number of rows is around 5000. Going forward, I would like to further increase the number of columns/financial-fields. For the above I would like to get help regarding: 1) What is the best database design approach? Is it ok to have these many number of columns? 2) How can it be normalized? (User can use any of these fields in search criteria). 3) Is it ok to stick with MySQL, or modern document based databases like MongoDB should be better for it? P.S. (Update): I have been using MySQL till now and a running example of the usage is at: http://screener.in/companies/89/Formula-- In above there around 500 fields/columns to create your query on, however, I seek to increase that number to much more in future.

• Small-scale database options for .NET

  - by raney

  I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

• Can't (re)install lazarus

  - by twice

  I had Lazarus installed (from website, not USC), while upgrading to 13.10 and after that, it posted some error message (which I can't remember) at every start. I decided it shouldn't suffer, so I started reinstalling it, but it didn't work. then I thought I'll start all over, and deleted and purged everything. But it still would not install. I found a similar, very similar question to mine here: Cant correctly install Lazarus I tried everything said there: sudo dpkg -l | grep "^rc" returned some packages: since sudo apt-get -f brought up the apt-get help message, and sudo apt-get -f install did nothing, I went ahead and manually purged every broken package, which seemed to bring me forward, since it removed the entries in sudo dpkg -l | grep "^rc". When I was done I tried it again, since it didn't work I rebooted, no change. this is the error message I get on the attempt to install the first package (fpc-2.6.2): root@Someone-PC:~# dpkg -i /home/someone/Desktop/fpc_2.6.2-0_amd64\ \(3\).deb (Reading database ... 242209 files and directories currently installed.)

• JavaOne + Develop Registration is Open!

  - by justin.kestelyn

  Welcome to "The Zone". Here's what the new JavaOne + Develop registration Website says: The world's most important developer conferences are creating the world's coolest neighborhood for the developer community. Having been intimately involved in the planning process, I can vouch for that statement. Remember, if either co-located conference - JavaOne or Oracle Develop - are the confines of your interest, you can experience either one in standalone mode, if you like (although there are some areas of common interest, of course). Or, considering that a single Full Conference Pass gives you access to both of them, you can partake in any measure that you like. It's up to you. Either way, you will get access not only to session content and keynotes, but also to the massive OTN Night party on Monday night, to open unconference sessions, and to the legendary Appreciate Night concert (acts TBD) on Wednesday. Furthermore, as is customary, the Oracle Technology Network team will offer a full slate of community-focused activities and goodies while the conferences are running - more details on those as we have them. A GOOD time is ensured for all; I look forward to seeing you there!

• How can I use domain masking without having self referral in Google Analytics

  - by Cdore

  I have one old domain that points to a website's server's ip (let's call it www.oldsite.com). I have a new one, www.newsite.com, that is set up to be forwarded to a specific page on the website. Due to the way the host of newsite.com places the website in a frame, in Google Analystics, the newsite.com is listed as a source rather than the source they were at before hand, causing a self referral. A solution is to edit the code of the iframe as I looked up, but there's no way to really edit the host's masking source code of course. Another solution I did previously was have www.newsite.com point to the address that www.oldsite.come pointed to. It solved the analytics problems, but in exchange, the url masking no longer worked. In the address bar, it came up as www.oldsite.com. Is there a way to make me have url masking and be able to forward to agree with google analytics? The server of the website is hosted on a cloud server, if this is anymore information.

• SQL Server DBA - How to get a good one!

  - by ETFairfax

  I'm a lone developer. I am currently developing an application which is seeing me get way way way out of my depth when it comes to SQL DBA'ing, and have come to realise that I should hire a DBA to help me (which has full support from the company). Problem is - who? This SO thread sees someone hire a DBA only to realise that they will probably cause more harm then good! Also, I have just had a bad experience with a ASP.NET/C# contractor that has let us down. So, can anyone out there on SO either... a) Offer their services. b) Forward me onto someone that could help. c) Give some tips on vetting a DBA. I know this isn't a recruitment site, so maybe some good answers for c) would be a benefit for other readers!! BTW: The database is SQL Server 2008. I'm running into performance issues (mainly timeouts) which I think would be sorted out by some proper indexing. I would also need the DBA to provide some sort of maintenance plan, and to review how our database will deal what we intend at throwing at it in the future!

• Ways to organize interface and implementation in C++

  - by Felix Dombek

  I've seen that there are several different paradigms in C++ concerning what goes into the header file and what to the cpp file. AFAIK, most people, especially those from a C background, do: foo.h class foo { private: int mem; int bar(); public: foo(); foo(const foo&); foo& operator=(foo); ~foo(); } foo.cpp #include foo.h foo::bar() { return mem; } foo::foo() { mem = 42; } foo::foo(const foo& f) { mem = f.mem; } foo::operator=(foo f) { mem = f.mem; } foo::~foo() {} int main(int argc, char *argv[]) { foo f; } However, my lecturers usually teach C++ to beginners like this: foo.h class foo { private: int mem; int bar() { return mem; } public: foo() { mem = 42; } foo(const foo& f) { mem = f.mem; } foo& operator=(foo f) { mem = f.mem; } ~foo() {} } foo.cpp #include foo.h int main(int argc, char* argv[]) { foo f; } // other global helper functions, DLL exports, and whatnot Originally coming from Java, I have also always stuck to this second way for several reasons, such as that I only have to change something in one place if the interface or method names change, that I like the different indentation of things in classes when I look at their implementation, and that I find names more readable as foo compared to foo::foo. I want to collect pro's and con's for either way. Maybe there are even still other ways? One disadvantage of my way is of course the need for occasional forward declarations.

• Quaternion LookAt for camera

  - by Homar

  I am using the following code to rotate entities to look at points. glm::vec3 forwardVector = glm::normalize(point - position); float dot = glm::dot(glm::vec3(0.0f, 0.0f, 1.0f), forwardVector); float rotationAngle = (float)acos(dot); glm::vec3 rotationAxis = glm::normalize(glm::cross(glm::vec3(0.0f, 0.0f, 1.0f), forwardVector)); rotation = glm::normalize(glm::quat(rotationAxis * rotationAngle)); This works fine for my usual entities. However, when I use this on my Camera entity, I get a black screen. If I flip the subtraction in the first line, so that I take the forward vector to be the direction from the point to my camera's position, then my camera works but naturally my entities rotate to look in the opposite direction of the point. I compute the transformation matrix for the camera and then take the inverse to be the View Matrix, which I pass to my OpenGL shaders: glm::mat4 viewMatrix = glm::inverse( cameraTransform->GetTransformationMatrix() ); The orthographic projection matrix is created using glm::ortho. What's going wrong?

• Does your organization still use the term "screens" to describe a user interface?

  - by bit-twiddler

  I have been in the field long enough to remember when the term "screen" entered our lexicon. As difficult as it is to believe, the early systems on which I worked had no user interface (UI), that is, unless one counts a keypunch machine and job listings as a user interface. These systems ran as "card image" production jobs back in a day when being a computer operator required a reasonably deep understanding of how computers worked. Flashing forward to today: I cringe every time I hear a systems practitioner use the term "screen." The metaphor no longer fits the medium. The term somewhat fit back when the user dialog consumed 100% of available monitor real estate; however, the term lost its relevance the moment we moved to windowed environments. With the above said, does your organization still use the term "screens" to describe an application's UI? Has anyone successfully purged the term from an organization? For those who do not use the term to describe UI dialog elements, what term do you use in place of “screen.”

• Trying to recover deleted Ubuntu partition

  - by user110984

  I made a mistake in logging into my 200 GB Ubuntu partition. I could not access Grub after that. Using a live CD I then ran Boot_Repair and apparently deleted the partition, I guess because I ran it from my 70 GB Windows partition. I can send the results of boot_info before that and of Boot_Repair. Then I ran TestDisk, which apparently found only dev/sda/ -320GB / 298 / GiB - WDC - WD3200BEVT-22A23T0 (Was there any more I could have done with TestDisk? I looked at the TestDisk_Step_By_Step example and found no way forward given that no other partitions turned up) I have run gpart and found this: /sda1 - 15 GB /sda2 - system reserved /sda3 - 70.15 GB /sda4 - extended 212.84 unallocated - 209.10 /sda5 - unknown 3.74 . I have been told I can recover the partition using gparted's Rescue start end command, but I don't know what to enter for start and end. [--EDIT: TestDisk Deeper Search stated that "the following partitions can't be recovered" and listed a 220-GB Linux partition 6 times. Then it stated that "The current number of heads per cylinder is 255 but the correct value may be 128" and I could try to change it in the Geometry menu (because apparently these are overlapping partitions) So should I do that?--]
