  • Recap: Oracle at the Gartner Business Intelligence Summit

    - by kimberly.billings
    Getting to Vegas was no fun. As anyone who lives in the Bay Area knows, the SF airport shuts down one runway when it rains, causing major havoc. So rain, rain, rain on Sunday meant delay, delay, delay at the airport. Needless to say, my 6:30 pm flight didn't land in Vegas until 3:00 am! But the travel pains were worth it. There was a lot to be learned at the Gartner BI Summit this year, and the uptick in attendance was reflected in strong booth traffic and engaging conversations in the Oracle booth. Oracle customer, Dawn Conant, Director, Business Intelligence at Beckman Coulter, generated a lot of interest in her presentation about migrating from Business Objects to Oracle Business Intelligence, Enterprise Edition with Oracle Database 11g. Dawn's story was a very relatable one, as many of the attendees had plans for similar projects. One of the most interesting Gartner-led sessions compared BI/DW megavendors, IBM, Oracle, SAP and Microsoft. According to Gartner analyst Rita Sallam, these megavendors control about two-thirds of the BI market. Sallem attributes this in part to the fact that organizations are expanding their definitions of BI to also include analytics and performance management. In doing so, they require greater integration of BI applications with a broader set of applications and middleware. In a related session, a panel of Gartner analysts compared the Magic Quadrants for BI Platforms; CPM; Data Quality; Data Integration Tools; and Data Warehouses. Oracle is a leader in all of the Magic Quadrants in which it participates and has the most complete stack including hardware and software, according to Donald Feinberg. Feinberg also commented that in situations with VLDW and solid mixed workloads, Oracle Exadata is making a big difference! var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); try { var pageTracker = _gat._getTracker("UA-13185312-1"); pageTracker._trackPageview(); } catch(err) {}

  • Getting Internet Explorer to Open Different Sets of Tabs Based on the Day of the Week

    - by Akemi Iwaya
    If you have to use Internet Explorer for work and need to open a different set of work-specific tabs every day, is there a quick and easy way to do it instead of opening each one individually? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader bobSmith1432 is looking for a quick and easy way to open different daily sets of tabs in Internet Explorer for his work: When I open Internet Explorer on different days of the week, I want different tabs to be opened automatically. I have to run different reports for work each day of the week and it takes a lot of time to open the 5-10 tabs I use to run the reports. It would be a lot faster if, when I open Internet Explorer, the tabs I needed would automatically load and be ready. Is there a way to open 5-10 different tabs in Internet Explorer depending on the day of the week? Example: Monday – 6 Accounting Pages Tuesday – 7 Billing Pages Wednesday – 5 HR Pages Thursday – 10 Schedule Pages Friday – 8 Work Summary/Order Pages Is there an easier way for Bob to get all those tabs to load and be ready to go each day instead of opening them individually every time? The Answer SuperUser contributor Julian Knight has a simple, non-script solution for us: Rather than trying the brute force method, how about a work around? Open up each set of tabs either in different windows, or one set at a time, and save all tabs to bookmark folders. Put the folders on the bookmark toolbar for ease of access. Each day, right-click on the appropriate folder and click on ‘Open in tab group’ to open all the tabs. You could put all the day folders into a top-level folder to save space if you want, but at the expense of an extra click to get to them. If you really must go further, you need to write a program or script to drive Internet Explorer. The easiest way is probably writing a PowerShell script. Special Note: There are various scripts shared on the discussion page as well, so the solution shown above is just one possibility out of many. If you love the idea of using scripts for a function like this, then make sure to browse on over to the discussion page to see the various ones SuperUser members have shared! Have something to add to the explanation? Sound off in the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • Why All The Hype Around Live Help?

    - by ruth.donohue
    I am pleased to introduce guest blogger, Damien Acheson today. Based in Cambridge, MA, Damien is the Product Marketing Manager for ATG’s Live Help products. Welcome, Damien!! BY DAMIEN ACHESON Why all the hype around live help? An eCommerce professional recently asked me: “Why all the hype around live chat and click to call?” I already have a customer service phone number that’s available to my online visitors. Why would I want to add live help? If anything, I want my website to reduce the number of calls to my contact center, not increase it!” The effect of adding live help to a website is counter-intuitive. Done right, live help doesn’t increase your call volume; it optimizes it by replacing traditional telephone calls with smarter, more productive, live voice and live chat interactions. This generates instant cost savings, and a measurable lift in sales and customer retention. A live help interaction differs from a traditional telephone call in six radical ways: Targeting. With live help you can target specific visitors at just the exact right time with a live call or live chat invitation based on hundreds of different parameters. For example, visitors who appear to hesitate before making a large purchase may receive a live help invitation, while others may not. Productivity. By reserving live voice to visitors with complex questions, and offering self-service and live chat for more simple interactions, agents with the right domain expertise can handle simultaneous queries and achieve substantial productivity gains. Routing. Live help interactions take into account visitors’ web context to intelligently route queries to the best available agent, thereby lifting first contact resolution. Context. Traditional telephone numbers force online customers to “change channels” and “start over” with a phone agent. With Live help, agents get the context of the web session and can instantly access the customer’s transaction details and account information, substantially reducing handle times. Interaction. Agents can solve a customer’s problem more effectively co-browsing and collaborating with the visitor in real-time to complete online forms and transactions. Analytics. Unlike traditional telephone numbers, live help allows you to tie Web analytics to customer satisfaction and agent performance indicators. To better understand these differences and advantages over traditional customer service, watch this demo on optimizing customer interactions with Live Help. Technorati Tags: ATG,Live Help,Commerce

  • Recording Topics manually and automatically

    - by maria.cozzolino(at)oracle.com
    When you are recording UPK topics, the default mode for recording is manual recording, where you tell the system when to record each screen shot. This mode allows you to take the exact screen shot you need. However, it does get a bit tedious when you are recording long topics, especially if you forget to take a few screen shots. In UPK 3.5, a new version of recording was introduced - Automatic Recording. It was designed to simplify the recording process by automatically capturing screen shots as you perform your transaction. If you haven't experimented with Automatic Recording, I'd recommend you give it a try - it might make your recording life easier. If you are recording with sound, you can also narrate your topic while recording it. To turn on Automatic Recording: 1. In Tools/Options, there are two recorder tabs. The first tab, under content defaults, includes settings that you may want to share between developers, like whether keyboard shortcuts are automatically captured. 2. The second tab is the one that contains the personal preferences, like screen shot capture key and whether to record automatically or manually. On this tab, choose the option for Automatic Recording. 3. Save the settings. Note that this setting will NOT impact content defaults; this is for your user only. When you launch the recorder, you will notice a slightly different message with guidance on how to start and stop automatic recording. Once you start recording, the recorder window is hidden until the end of the recording session to allow you to capture your transaction. In the task tray, there is a series of icons that let you know that you are capturing content. You can pause the recording, as well as set and view your sound levels if you are using sound. A camera appears during each screen capture to help you know when the system is capturing a screen shot, and a context indicator appears to show the recognition. With automatic recording, you can let the system capture the necessary screen shots. It may provide a more natural recording experience, and is probably easier for the untrained developer. On the other hand, you have a bit more control with manual recording on which screen shot appears, but it also means you have to remember to capture the screen shot. :) We'd be interested in hearing which type of recording you do, and any rationale on why you made that choice. Please comment and let us know. --Maria Cozzolino, Manager of UPK Software Requirements and UI Design

  • Travelling MVP #3: Community event in Varna, Bulgaria

    - by DigiMortal
    Second stop in my DevReach 2012 trip was at Varna. We had not much time to hang around there but this problem will get fixed next year if not before. But still we had sessions there with Dimitar Georgijev and I had also chance to meet local techies. Next time we will have more tech and beers for sure! We started in the morning from Bucharest and travelled through Ruse, Razgrad and Shumen to Varna. It’s about 275km. We used cab, local bus and Dimitar father’s car. We had one food stop in Ruse and after that we went directly to Varna. Here is our route on map. Varna is Bulgarian city that locates on western coast of Black Sea. I have been there once before this trip and it’s good place to have vacation under sun. Also autumn is there milder than here in Estonia (third day of snow is going on). Bulgaria has some good beers, my favorite mankind killer called rakia and very good national cuisine. Food is made of fresh stuff and it is damn good experience. Here are some arbitrarily selected images (you can click on these to view at original size): Old bus “monument” in Razgrad Stuffed peppers, Bulgarian national cuisine Infra-red community having good time and beers We made our sessions at one study class of Varna technical university. It’s a little bit old style university but everything we needed was there and we had no problems with machinery. Sessions were same as in Bucharest. The user group in Varna is brand new and hopefully it will be something bigger one good day. At least I try to make my commits so they get on their feet quicker. As we had not much time to announce the event there was about 15 guys listening to us and I’m happy that it was not too much hyped event because still I was getting my first experiences with foreign audiences. After sessions we took our stuff to hotel and went to hang around with local techies. We had some good time there and made some new friends. Next time when I go to Varna I go back as more experienced speaker and I plan to do there one tougher and highly challenging session. Maybe somebody from Estonian community will join me and then it will be well planned surprise-attack to Varna :)

  • OTN Latinoamérica Tour 2012

    - by Dana Singleterry
    Better late than never. Sorry for the delay on getting this content up for all of you and thanks again for your attendance. A number of excellent questions came out of the sessions I delivered and herein I'm providing you with the content, in pdf format, for those sessions. I'm also providing pointers to Forms to ADF integration/migration as well as some details around OAF as used in E-Business Suite and ADF. Here's the sessions delivered by location. Click on any of the links to download the session content in pdf format. Montevideo Uruguay: Is Oracle ADF Simpler than Oracle Forms? Understanding the Fusion Development Platform Building Web Data Dashboards Without Coding Buenos Aires, Argentina: Is Oracle ADF Simpler than Oracle Forms? Developing Cross Device Mobile Applications Sao Paulo, Brazil Understanding the Fusion Development Platform Is Oracle ADF Simpler than Oracle Forms? A brief note on Form Integration & Migration: Does your organization have an Oracle Forms application that you'd like to migrate to ADF? Or, perhaps you're an Oracle Forms Developer and want to modernize your application development skills? If so, you've come to the right place! This section will strive to answer common questions that arise as you move from Forms to ADF. Our Oracle Forms Statement of Direction points out that Oracle is committed to the long-term support of Oracle Forms and Reports. However, many customers feel they are outgrowing their Forms applications. Users are demanding more sophisticated and interactive users interfaces. Executives are requiring SOA-enabled applications that integrate with peripheral services. Development leads are encouraging a more modern approach to application development, including adherence to design patterns like MVC. So even as Oracle still supports Forms, the list of reasons to move off of it is becoming more compelling and is only gaining further momentum by the fact that Oracle's own Fusion Applications are using ADF. Developers and organizations looking to align with both the technology stack and look-and-feel of Fusion Applications are choosing ADF, and thus reaping the benefits of years of best practices in enterprise application development that are baked into the ADF framework. So, if you decide to migrate off of Forms for any of these reasons, ADF is the way to go. Grant Ronald has published a video of our position on the subject, along with an ODTUG article explaining our direction. These materials explain that there are other migration tools/frameworks/paths, but the best choice is usually to follow Gartner's recommendation that if you are going to migrate off of Oracle Forms, ADF is the least risky and least costly migration path. Please visit the Oracle Forms page here. For details around OAF as used in E-Business Suite (EBS) and when to use ADF with EBS you can review the following blogs from Shay Shmeltzer. To ADF or to OAF? or Can I use ADF with Oracle E-Business Suite?

  • Case Management Patterns with Oracle Unified Business Process Management Suite

    - by Ajay Khanna
    Contributed by Heidi Buelow, Oracle Product Management Case Management was a hot topic all week at Oracle OpenWorld so I was excited to share our current features and upcoming plans at the session Thursday morning on Case Management Patterns with Oracle Unified Business Process Management Suite.  My colleague, Ravi Rangaswamy, the Case Management Development Manager, and I, Heidi Buelow, the Case Management Product Manager, discussed case management use case patterns with an interested audience.  We also talked about the current BPM Suite offering for Case Managment and showed a demo of our upcoming release where Case Management becomes a first class component in a BPM composite application. Case Management use case patterns cover a wide range of horizontal applications such as Accounts Payable, Dispute Resolution, Call Center, Employee OnBoarding, and many vertical applications in domains and industries such as Public Sector services, Insurance claims, and Healthcare.  Really, it is any use case where the resolution of a request may require a knowledge worker making decisions using experienced judgement in the current situation.  This allows for expidited care and customer satisfaction, both being highly valued for consumer loyalty, regulatory compliance, and efficient resolution. Today, BPM Suite provides the tools for creating Case Management applications using BPMN 2.0, Business Rules, and rich BAM and Case Analytics.  The Process Composer provides the agility to change rules and processes by the business users.  The case manager and case workers have the flexibilty they need.  With integrated content management and the concept of a BPM Process Spaces instance (case) space, the current release enables case management use case applications. In the next release, Case Management becomes a first class component. By this, we mean, Case is a separate component in the composite.  We are adding case attributes such as milestones, case events, case stakeholders, and more, providing a rich toolset for the use cases that require a flexible Case Management approach.  Activites become available according to the conditions that you specify and information can be protected by permissions indicated.  In BPM Studio, you design a Case and associate all of the attributes and activities that are needed, yet, at runtime you have the flexibility to add and change these as needed. We enjoyed sharing Case Management and it was well received by the audience.  The presentation is available online and we have viewlets of the demo that will be available at release time.

  • Advice on designing a robust program to handle a large library of meta-information & programs

    - by Sam Bryant
    So this might be overly vague, but here it is anyway I'm not really looking for a specific answer, but rather general design principles or direction towards resources that deal with problems like this. It's one of my first large-scale applications, and I would like to do it right. Brief Explanation My basic problem is that I have to write an application that handles a large library of meta-data, can easily modify the meta-data on-the-fly, is robust with respect to crashing, and is very efficient. (Sorta like the design parameters of iTunes, although sometimes iTunes performs more poorly than I would like). If you don't want to read the details, you can skip the rest Long Explanation Specifically I am writing a program that creates a library of image files and meta-data about these files. There is a list of tags that may or may not apply to each image. The program needs to be able to add new images, new tags, assign tags to images, and detect duplicate images, all while operating. The program contains an image Viewer which has tagging operations. The idea is that if a given image A is viewed while the library has tags T1, T2, and T3, then that image will have boolean flags for each of those tags (depending on whether the user tagged that image while it was open in the Viewer). However, prior to being viewed in the Viewer, image A would have no value for tags T1, T2, and T3. Instead it would have a "dirty" flag indicating that it is unknown whether or not A has these tags or not. The program can introduce new tags at any time (which would automatically set all images to "dirty" with respect to this new tag) This program must be fast. It must be easily able to pull up a list of images with or without a certain tag as well as images which are "dirty" with respect to a tag. It has to be crash-safe, in that if it suddenly crashes, all of the tagging information done in that session is not lost (though perhaps it's okay to loose some of it) Finally, it has to work with a lot of images (10,000) I am a fairly experienced programmer, but I have never tried to write a program with such demanding needs and I have never worked with databases. With respect to the meta-data storage, there seem to be a few design choices: Choice 1: Invidual meta-data vs centralized meta-data Individual Meta-Data: have a separate meta-data file for each image. This way, as soon as you change the meta-data for an image, it can be written to the hard disk, without having to rewrite the information for all of the other images. Centralized Meta-Data: Have a single file to hold the meta-data for every file. This would probably require meta-data writes in intervals as opposed to after every change. The benefit here is that you could keep a centralized list of all images with a given tag, ect, making the task of pulling up all images with a given tag very efficient

  • Find a Faster DNS Server with Namebench

    - by Mysticgeek
    One way to speed up your Internet browsing experience is using a faster DNS server. Today we take a look at Namebench, which will compare your current DNS server against others out there, and help you find a faster one. Namebench Download the file and run the executable (link below). Namebench starts up and will include the current DNS server you have configured on your system. In this example we’re behind a router and using the DNS server from the ISP. Include the global DNS providers and the best available regional DNS server, then start the Benchmark. The test starts to run and you’ll see the queries it’s running through. The benchmark takes about 5-10 minutes to complete. After it’s complete you’ll get a report of the results. Based on its findings, it will show you what DNS server is fastest for your system. It also displays different types of graphs so you can get a better feel for the different results. You can export the results to a .csv file as well so you can present the results in Excel. Conclusion This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. If you’re looking for a method to help find a faster DNS server for your system, Namebench is a cool free utility to help you out. If you’re looking for a public DNS server that is customizable and includes filters, you might want to check out our article on helping to protect your kids from questionable content using OpenDNS. You can also check out how to speed up your web browsing with Google Public DNS.

  • VSDB to SSDT Part 1 : Converting projects and trimming excess files

    - by Etienne Giust
    Visual Studio 2012 introduces a change regarding Database Projects : they now use the SSDT technology, which means old VS2010 database projects (VSDB projects) need to be converted. Hopefully, VS2012 does that for you and it is quite painless, but in my case some unnecessary artifacts from the old project were left in place.  Also, when reopening the solution, database projects appeared unconverted even if I had converted them in the previous session and saved the solution.   Converting the project(s) When opening your Visual Studio 2010 solution with Visual Studio 2012, every standard project should be converted by default, but Visual Studio will ask you about your database projects : “Functional changes required Visual Studio will automatically make functional changes to the following projects in order to open them. The project behavior will change as a result. You will be able to open these projects in this version and Visual Studio 2010 SP1.” If you accept, your project is converted. And it should compile with no errors right away except if you have dependencies to dbschema files which are no longer supported.   The output of a SSDT project is a dacpac file which replaces the dbschema file you were accustomed to. References to dacpac files can be added to SSDT projects in the same fashion references to dbschema could be added to VSDB projects.   Cleaning up You will notice that your project file is now a sqlproj file but the old dbproj is still here. In fact at that point you can still reopen the solution in Visual Studio 2010 and everything should show up.   If like me you plan on using VS2012 exclusively, you can get rid of the following files which are still on your disk and in your source control : the dbproj and dbproj.vspscc files Properties/Database.sqlcmdvars Properties/Database.sqldeployment Properties/Database.sqlpermissions Properties/Database.sqlsettings   You might wonder where the information which used to be in the Properties files is now stored. Permissions : a Permissions.sql was created at the root level of your project. Note that when you create a new database project and import a database using the Schema Compare capabilities from Visual Studio, imported table and stored procedure definition files will hold the permission information (along with constraints and, indexes) SQLVars : they are defined inside the publish.xml files Deployment : they are also in the publish.xml files Settings : I was unable to find where those are now. I suppose they are not defined anymore   But Visual Studio still says my database projects should be converted ! I had this error upon closing and then re-opening the solution : my database projects would appear unconverted even though I did all the necessary steps previously.   Easy solution : remove those projects from the solution and add them again (the sqlproj files).   More For those who run into problems when converting from VSDB to SSDT, I suggest reading the following post : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/top-vsdb-gt-ssdt-project-conversion-issues.aspx   Also interesting, is a side by side comparison of VSDB and SSDT project features : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/sql-server-data-tools-ctp4-vs-vs2010-database-projects.aspx

  • Lubuntu Desktop messed up for logged in user, but not for guest

    - by RPi Awesomeness
    I recently upgraded my laptop from Lubuntu 12.04 to 14.04.1 and the upgrade process seemed to go fine. However, when I went to login as my normal user, I encountered an issue. The background loaded up, but none of LXDE or LXPanel showed up, leaving me with an empty desktop and nothing else except two errors. I thought that this was weird, so I just figured something had been messed up and would be fixed by a reboot. But it wasn't. I then tried logging in as guest, and it's just fine. I checked the ~/.xsession-errors file (for my main user, not guest, did it via TTY1) and this is what I got: Script for ibus started at run_im. Script for auto started at run_im. Script for default started at run_im. init: Unable to register as subreaper: Invalid argument init: lxsession main process (1649) killed by TERM signal init: Disconnected from notified D-Bus bus init: job dbus failed to stop init: job upstart-dbus-session-bridge failed to stop init: job upstart-dbus-system-bridge failed to stop init: job upstart-file-bridge failed to stop I also read the sometimes removing the ~/.Xauthority file can help, if the ownership is messed up. ls -l /home/MYUSER/.Xauthority tells me -rw------- 1 MYUSER MYUSER 60 Aug 16 09:57 /home/MYUSER/.Xauthority. Should that be root or something else, or should I try deleting that and ~/.profile. Here's what ~/.profile looks like: # ~/.profile: executed by the command interpreter for login shells. # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # see /usr/share/doc/bash/examples/startup-files for examples. # the files are located in the bash-doc package. # the default umask is set in /etc/profile; for setting the umask # for ssh logins, install and configure the libpam-umask package. #umask 022 # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi Should I post the output of dmesg? I'll try and get a screenshot, but does anyone have any idea what could be causing the desktop (LXDE/LXPanel) not to display? EDIT I attempted removing the ~/.XAuthority file, but that didn't seem to do anything.

  • XNA: Networking gone totally out of sync

    - by MesserChups
    I'm creating a multiplayer interface for a game in 2D some of my friends made, and I'm stuck with a huge latency or sync problem. I started by adapting my game to the msdn xna network tutorial and right now when I join a SystemLink network session (1 host on PC and 1 client on Xbox) I can move two players, everything is ok, but few minutes later the two machines start being totally out of synchronization. When I move one player it takes 10 or 20 seconds (increasing with TIME) to take effect on the second machine. I've tried to : Create a thread which calls NetworkSession.Update() continuously as suggested on this forum, didn't worked. Call the Send() method one frame on 10, and the receive() method at each frame, didn't worked either. I've cleaned my code, flushed all buffers at each call and switched the host and client but the problem still remain... I hope you have a solution because I'm running out of ideas... Thanks SendPackets() code : protected override void SendPackets() { if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { //Write in the packet manager m_packetWriter.Write(m_packetManager.PacketToSend.ToArray(), 0, (int)m_packetManager.PacketToSend.Position); m_packetManager.ResetPacket(); //flush //Sends the packets to all remote gamers foreach (NetworkGamer l_netGamer in m_networkSession.RemoteGamers) { if (m_packetWriter.Length != 0) { FirstLocalNetGamer.SendData(m_packetWriter, SendDataOptions.None, l_netGamer); } } m_packetWriter.Flush();//m m_packetWriter.Seek(0, 0); } } ReceivePackets() code : public override void ReceivePackets() { base.ReceivePackets(); if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { if (m_networkSession.LocalGamers.Count > 0) //Verify that there's at least one local gamer { foreach (LocalNetworkGamer l_localGamer in m_networkSession.LocalGamers) { //every LocalNetworkGamer must read to flush their stream // Keep reading while packets are available. NetworkGamer l_oldSender = null; while (l_localGamer.IsDataAvailable) { // Read a single packet, even if we are the host, we must read to clear the queue NetworkGamer l_newSender; l_localGamer.ReceiveData(m_packetReader, out l_newSender); if (l_newSender != l_oldSender) { if ((!l_newSender.IsLocal) && (l_localGamer == FirstLocalNetGamer)) { //Parsing PacketReader to MemoryStream m_packetManager.Receive(new MemoryStream(m_packetReader.ReadBytes(m_packetReader.Length))); } } l_oldSender = l_newSender; m_packetReader.BaseStream.Flush(); m_packetReader.BaseStream.Seek(0, SeekOrigin.Begin); } } m_packetManager.ParsePackets(); } } }

  • 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!

  • 3D picking lwjgl

    - by Wirde
    I have written some code to preform 3D picking that for some reason dosn't work entirely correct! (Im using LWJGL just so you know.) I posted this at stackoverflow at first but after researching some more in to my problem i found this neat site and tought that you guys might be more qualified to answer this question. This is how the code looks like: if(Mouse.getEventButton() == 1) { if (!Mouse.getEventButtonState()) { Camera.get().generateViewMatrix(); float screenSpaceX = ((Mouse.getX()/800f/2f)-1.0f)*Camera.get().getAspectRatio(); float screenSpaceY = 1.0f-(2*((600-Mouse.getY())/600f)); float displacementRate = (float)Math.tan(Camera.get().getFovy()/2); screenSpaceX *= displacementRate; screenSpaceY *= displacementRate; Vector4f cameraSpaceNear = new Vector4f((float) (screenSpaceX * Camera.get().getNear()), (float) (screenSpaceY * Camera.get().getNear()), (float) (-Camera.get().getNear()), 1); Vector4f cameraSpaceFar = new Vector4f((float) (screenSpaceX * Camera.get().getFar()), (float) (screenSpaceY * Camera.get().getFar()), (float) (-Camera.get().getFar()), 1); Matrix4f tmpView = new Matrix4f(); Camera.get().getViewMatrix().transpose(tmpView); Matrix4f invertedViewMatrix = (Matrix4f)tmpView.invert(); Vector4f worldSpaceNear = new Vector4f(); Matrix4f.transform(invertedViewMatrix, cameraSpaceNear, worldSpaceNear); Vector4f worldSpaceFar = new Vector4f(); Matrix4f.transform(invertedViewMatrix, cameraSpaceFar, worldSpaceFar); Vector3f rayPosition = new Vector3f(worldSpaceNear.x, worldSpaceNear.y, worldSpaceNear.z); Vector3f rayDirection = new Vector3f(worldSpaceFar.x - worldSpaceNear.x, worldSpaceFar.y - worldSpaceNear.y, worldSpaceFar.z - worldSpaceNear.z); rayDirection.normalise(); Ray clickRay = new Ray(rayPosition, rayDirection); Vector tMin = new Vector(), tMax = new Vector(), tempPoint; float largestEnteringValue, smallestExitingValue, temp, closestEnteringValue = Camera.get().getFar()+0.1f; Drawable closestDrawableHit = null; for(Drawable d : this.worldModel.getDrawableThings()) { // Calcualte AABB for each object... needs to be moved later... firstVertex = true; for(Surface surface : d.getSurfaces()) { for(Vertex v : surface.getVertices()) { worldPosition.x = (v.x+d.getPosition().x)*d.getScale().x; worldPosition.y = (v.y+d.getPosition().y)*d.getScale().y; worldPosition.z = (v.z+d.getPosition().z)*d.getScale().z; worldPosition = worldPosition.rotate(d.getRotation()); if (firstVertex) { maxX = worldPosition.x; maxY = worldPosition.y; maxZ = worldPosition.z; minX = worldPosition.x; minY = worldPosition.y; minZ = worldPosition.z; firstVertex = false; } else { if (worldPosition.x > maxX) { maxX = worldPosition.x; } if (worldPosition.x < minX) { minX = worldPosition.x; } if (worldPosition.y > maxY) { maxY = worldPosition.y; } if (worldPosition.y < minY) { minY = worldPosition.y; } if (worldPosition.z > maxZ) { maxZ = worldPosition.z; } if (worldPosition.z < minZ) { minZ = worldPosition.z; } } } } // ray/slabs intersection test... // clickRay.getOrigin().x + clickRay.getDirection().x * f = minX // clickRay.getOrigin().x - minX = -clickRay.getDirection().x * f // clickRay.getOrigin().x/-clickRay.getDirection().x - minX/-clickRay.getDirection().x = f // -clickRay.getOrigin().x/clickRay.getDirection().x + minX/clickRay.getDirection().x = f largestEnteringValue = -clickRay.getOrigin().x/clickRay.getDirection().x + minX/clickRay.getDirection().x; temp = -clickRay.getOrigin().y/clickRay.getDirection().y + minY/clickRay.getDirection().y; if(largestEnteringValue < temp) { largestEnteringValue = temp; } temp = -clickRay.getOrigin().z/clickRay.getDirection().z + minZ/clickRay.getDirection().z; if(largestEnteringValue < temp) { largestEnteringValue = temp; } smallestExitingValue = -clickRay.getOrigin().x/clickRay.getDirection().x + maxX/clickRay.getDirection().x; temp = -clickRay.getOrigin().y/clickRay.getDirection().y + maxY/clickRay.getDirection().y; if(smallestExitingValue > temp) { smallestExitingValue = temp; } temp = -clickRay.getOrigin().z/clickRay.getDirection().z + maxZ/clickRay.getDirection().z; if(smallestExitingValue < temp) { smallestExitingValue = temp; } if(largestEnteringValue > smallestExitingValue) { //System.out.println("Miss!"); } else { if (largestEnteringValue < closestEnteringValue) { closestEnteringValue = largestEnteringValue; closestDrawableHit = d; } } } if(closestDrawableHit != null) { System.out.println("Hit at: (" + clickRay.setDistance(closestEnteringValue).x + ", " + clickRay.getCurrentPosition().y + ", " + clickRay.getCurrentPosition().z); this.worldModel.removeDrawableThing(closestDrawableHit); } } } I just don't understand what's wrong, the ray are shooting and i do hit stuff that gets removed but the result of the ray are verry strange it sometimes removes the thing im clicking at, sometimes it removes things thats not even close to what im clicking at, and sometimes it removes nothing at all. Edit: Okay so i have continued searching for errors and by debugging the ray (by painting smal dots where it travles) i can now se that there is something oviously wrong with the ray that im sending out... it has its origin near the world center (nearer or further away depending on where on the screen im clicking) and always shots to the same position no matter where I direct my camera... My initial toughts is that there might be some error in the way i calculate my viewMatrix (since it's not possible to get the viewmatrix from the gluLookAt method in lwjgl; I have to build it my self and I guess thats where the problem is at)... Edit2: This is how i calculate it currently: private double[][] viewMatrixDouble = {{0,0,0,0}, {0,0,0,0}, {0,0,0,0}, {0,0,0,1}}; public Vector getCameraDirectionVector() { Vector actualEye = this.getActualEyePosition(); return new Vector(lookAt.x-actualEye.x, lookAt.y-actualEye.y, lookAt.z-actualEye.z); } public Vector getActualEyePosition() { return eye.rotate(this.getRotation()); } public void generateViewMatrix() { Vector cameraDirectionVector = getCameraDirectionVector().normalize(); Vector side = Vector.cross(cameraDirectionVector, this.upVector).normalize(); Vector up = Vector.cross(side, cameraDirectionVector); viewMatrixDouble[0][0] = side.x; viewMatrixDouble[0][1] = up.x; viewMatrixDouble[0][2] = -cameraDirectionVector.x; viewMatrixDouble[1][0] = side.y; viewMatrixDouble[1][1] = up.y; viewMatrixDouble[1][2] = -cameraDirectionVector.y; viewMatrixDouble[2][0] = side.z; viewMatrixDouble[2][1] = up.z; viewMatrixDouble[2][2] = -cameraDirectionVector.z; /* Vector actualEyePosition = this.getActualEyePosition(); Vector zaxis = new Vector(this.lookAt.x - actualEyePosition.x, this.lookAt.y - actualEyePosition.y, this.lookAt.z - actualEyePosition.z).normalize(); Vector xaxis = Vector.cross(upVector, zaxis).normalize(); Vector yaxis = Vector.cross(zaxis, xaxis); viewMatrixDouble[0][0] = xaxis.x; viewMatrixDouble[0][1] = yaxis.x; viewMatrixDouble[0][2] = zaxis.x; viewMatrixDouble[1][0] = xaxis.y; viewMatrixDouble[1][1] = yaxis.y; viewMatrixDouble[1][2] = zaxis.y; viewMatrixDouble[2][0] = xaxis.z; viewMatrixDouble[2][1] = yaxis.z; viewMatrixDouble[2][2] = zaxis.z; viewMatrixDouble[3][0] = -Vector.dot(xaxis, actualEyePosition); viewMatrixDouble[3][1] =-Vector.dot(yaxis, actualEyePosition); viewMatrixDouble[3][2] = -Vector.dot(zaxis, actualEyePosition); */ viewMatrix = new Matrix4f(); viewMatrix.load(getViewMatrixAsFloatBuffer()); } Would be verry greatfull if anyone could verify if this is wrong or right, and if it's wrong; supply me with the right way of doing it... I have read alot of threads and documentations about this but i can't seam to wrapp my head around it... Edit3: Okay with the help of Byte56 (thanks alot for the help) i have now concluded that it's not the viewMatrix that is the problem...

  • From J2EE to Java EE: what has changed?

    - by Bruno.Borges
    See original @Java_EE tweet on 29 May 2014 Yeap, it has been 8 years since the term J2EE was replaced, and still some people refer to it (mostly recruiters, luckily!). But then comes the question: what has changed besides the name? Our community friend Abhishek Gupta worked on this question and provided an excellent response titled "What's in a name? Java EE? J2EE?". But let me give you a few highlights here so you don't lose yourself with YATO (yet another tab opened): J2EE used to be an infrastructure and resources provider only, requiring developers to depend on external 3rd-party frameworks to then implement application requirements or improve productivity J2EE used to require hundreds of XML lines of codes to define just a dozen of resources like EJBs, MDBs, Servlets, and so on J2EE used to support only EAR (Enterprise Archives) with a bunch of other archives like JARs and WARs just to run a simple Web application And so on, and so on! It was a great technology but still required a lot of work to get something up and running. Remember xDoclet? Remember Struts? The old days of pure Hibernate code? Or when Ajax became a trending topic and we were all implementing it with DWR Servlet? Still, we J2EE developers survived, and learned, and helped evolve the platform to a whole new level of DX (Developer Experience). A new DX for J2EE suggested a new name. One that referred to the platform as the Enterprise Edition of Java, because "Java is why we're here" quoting Bill Shannon. The release of Java EE 5 included so many features that clearly showed developers the platform was going after all those DX gaps. Radical simplification of the persistence model with the introduction of JPA Support of Annotations following the launch of Java SE 5.0 Updated XML APIs with the introduction of StAX Drastic simplification of the EJB component model (with annotations!) Convention over Configuration and Dependency Injection A few bullets you may say but that represented a whole new DX and a vision for upcoming versions. Clearly, the release of Java EE 5 helped drive the future of the platform by reducing the number of XMLs, Java Interfaces, simplified configurations, provided convention-over-configuration, etc! We then saw the release of Java EE 6 with even more great features like Managed Beans, CDI, Bean Validation, improved JSP and Servlets APIs, JASPIC, the posisbility to deploy plain WARs and so many other improvements it is difficult to list in one sentence. And we've gotta give Spring Framework some credit here: thanks to Rod Johnson and team, concepts like Dependency Injection fit perfectly into the Java EE Platform. Clearly, Spring used to be one of the most inspiring frameworks for the Java EE platform, and it is great to see things like Pivotal and Spring supporting JSR 352 Batch API standard! Cooperation to keep improving DX at maximum in the server-side Java landscape.  The master piece result of these previous releases is seen and called today as Java EE 7, which by providing a newly and improved JavaServer Faces release, with new features for Web Development like WebSockets API, improved JAX-RS, and JSON-P, but also including Batch API and so many other great improvements, has increased developer productivity and brought innovation to server-side Java developers. Java EE is not just a new name (which was introduced back in May 2006!) but a new Developer Experience for server-side Java developers. To show you why we are here and where we are going (see the Java EE 8 update), we wanted to share with you a draft of the new Java EE logos that the evangelist team created, to help you spread the word about Java EE. You can get access to these images at the Java EE Platform Facebook Album, or the Google+ Java EE Platform Album whichever is better for you, but don't forget to like and/or +1 those social network profiles :-) A message to all job recruiters: stop using J2EE and start using Java EE if you want to find great Java EE 5, Java EE 6, or Java EE 7 developers To not only save you recruiter valuable characters when tweeting that job opportunity but to also match the correct term, we invite you to replace long terms like "Java/J2EE" or even worse "#Java #J2EE #JEE" or all these awkward combinations with the only acceptable hashtag: #JavaEE. And to prove that Java EE is catching among developers and even recruiters, and that J2EE is past, let me highlight here how are the jobs trends! The image below is from Indeed.com trends page, for the following keywords: J2EE, Java/J2EE, Java/JEE, JEE. As you can see, J2EE is indeed going away, while JEE saw some increase. Perhaps because some people are just lazy to type "Java" but at the same time they are aware that J2EE (the '2') is past. We shall forgive that for a while :-) Another proof that J2EE is going away is by looking at its trending statistics at Google. People have been showing less and less interest in the term J2EE. See the chart below:  Recruiter, if you still need proof that J2EE is past, that Java EE is trending, and that other job recruiters are seeking for Java EE developers, and that the developer community is aware of the new term, perhaps these other charts can show you what term you should be using. See for example the Job Trends for Java EE at Indeed.com and notice where it started... 2006! 8 years ago :-) Last but not least, the Google Trends for Java EE term (including the still wrong but forgivable JavaEE term) shows us that the new term is catching up very well. J2EE is past. Oh, and don't worry about the curves going down. We developers like to be hipsters sometimes and today only AngularJS, NodeJS, BigData are going up. Java EE and other traditional server-side technologies such as Spring, or even from other platforms such as Ruby on Rails, PHP, Grails, are pretty much consolidated and the curves... well, they are consolidated too. So If you are a Java EE developer, drop that J2EE from your résumé, and let recruiters also know that this term is past. Embrace Java EE, and enjoy a new developer experience for server-side Java developers. Java EE on TwitterJava EE on Google+Java EE on Facebook

  • Finally, upgrade from Nokia X3 to Samsung Galaxy S III

    This time, something slightly different but nonetheless not less interesting, hopefully. Living on a remote island like Mauritius, ill-praised 'Cyber Island' in the Indian Ocean, has its advantages in life style and relaxed environment to life in but in terms of technological aspects it can be quite a nightmare. Well, I guess this might be different story to report about... one day. Cyber Island Mauritius Despite it's shiny advertisement as Cyber Island and business in ICT hub to Africa, Mauritius is not on the latest track of available models in computer hardware or, in the context of this article, cellulars or smart-phone, or communication technology in general. Okay, I have to admit that this statement is only partly true. Money can buy, even here in Mauritius. Luckily, there are ways and ways to deal with this outcry of modern, read: technological, civilisation issues. Online shopping you might think? Yes, for sure, until you discover in your checkout procedure that a small island in the Indian Ocean isn't a preferred destination for delivery and the precious time you spent on putting your items into your cart and feeding your personal level of anticipation gets ruined on the last stint. Ordering from abroad saves you money Anyway, I got in touch with my personal courier and luckily there were some extra-kilos left in the luggage. First obstacle sorted, we have a Transporter! Okay, on the next occasion off to Amazon online and using their Prime service for fast delivery. Actually, the order was placed on Saturday evening and everything got delivered on Tuesday morning - nice job in less than 72 hours. Okay, among the items of that shopping rush I ordered a shiny Samsung Galaxy S III 16GB in oceanic blue - did I mention, that you hardly get a blue model in Mauritius? - for my BWE. Interesting side-notes: First, Amazon Germany dropped the prices for roughly 30% on the S3, and we got the 16GB model for less than 500 Euro (or approx. Rs. 19.500,-) compared to the usual Rs. 27.000,- on the local market. It even varies whether the local price is inclusive or exclusive VAT (15%). Second, since a while she was bothering me to get an iPhone and an iPad for her, fair enough I thought, decent hardware, posh design and reliable services. Until we watched the 'magical' introduction of Samsung's new models at the IFA exhibition, she read the bashing comments on Google+ on the iPhone 5 and I gave her a brief summary on the law suit between Apple and Samsung in the USA. So, yes, Samsung USA is right, the next big thing is already here - literally. My BWE loves the look and touch of the Galaxy S3. And for me it was more cost-effective in terms of purchases done at the App Store, ups, Play Store. Transfer of contacts, text messages and media files Okay, now that the hardware is in place, how to transfer all those contacts, text messages, media files, etc. between those two devices? In the past, I used to use the Nokia Communication Suite between various models but now for Android? Well, as usual Google and Bing are reliable friends and among the first hits I came across an article about How to Transfer Contacts from Nokia to Android. Couldn't be easier, right? Well, sort of... my main Windows systems are already running on Windows 8, and this actually caused problems with the mobile/smart-phone device drivers. The article provides the download for an older version 1.10 which upgrades to 2.11 (as time of writing this entry) but both couldn't get the Galaxy S3 and the Nokia connected. Shame on me... the product page clearly doesn't mention Windows 8 (for now) and Windows 8 isn't available for the general audience at all... After I took a spare machine running on Windows Vista everything went smooth. Software installed, upgrade done, device drivers for Android automatically downloaded and installed, and the same painless routine for the Nokia part. I think, I rebooted the system twice during the whole setup procedure but hey, it was more or less a distraction while coding some stuff in ASP.NET MVC and Telerik Kendo UI. The transfer of contacts and text messages was done via Wondershare MobileGo for Android, and all media files by moving the additional microSD card from one device to the other. But even without an external SD card, it would have been very easy to copy the files via Windows Explorer directly. Little catch and excellent service Fine, we are almost done and the only step left is to shift the SIM card... Ouch, gotcha! The X3 uses a standard size SIM card while the S III only accepts microSIM form factor. What an irony, bigger smartphone needs smaller SIM card. Luckily, the next showroom of Emtel is just 5 mins away up the road, and the service staff over there know their job. Finally, after roughly 10 mins of paper work, activation and small chit-chat, the S3 came to life on the mobile network. Owning a smart-phone now and knowing that my BWE would like to interact more on social networks away from home, especially to upload pictures and provide local 'check-ins', I activated a data package for her in advance, too. Even that it is Saturday, everything was already done and ready to be used. Nice bonus: The Emtel clerk directly offered me to set up the configuration for the Emtel data services, yes sure, go ahead, this saves me to search for that in the settings. Okay, spoiler-alert here, setting a static APN to access the Emtel network and the internet wouldn't be a challenge. But hey, she already had the phone in her hands and I could keep my eyes on the children. Well done, Emtel! Resume Thanks to the useful software package by Wondershare is was a hands-free experience to transfer all the data from a Nokia mobile on Symbian S60 to a Samsung Galaxy S III on Android Ice Cream Sandwich (ICS). In the future, this wont be a serious issue at all anymore thanks to synchronisation services and cloud storage. And for now, I'm only waiting for the official upgrades for Jelly Bean.
