  • JCP Awards 10 Year Retrospective

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

  • Talking JavaOne with Rock Star Kirk Pepperdine

    - by Janice J. Heiss
    Kirk Pepperdine is not only a JavaOne Rock Star but a Java Champion and a highly regarded expert in Java performance tuning who works as a consultant, educator, and author. He is the principal consultant at Kodewerk Ltd. He speaks frequently at conferences and co-authored the Ant Developer's Handbook. In the rapidly shifting world of information technology, Pepperdine, as much as anyone, keeps up with what's happening with Java performance tuning. Pepperdine will participate in the following sessions: CON5405 - Are Your Garbage Collection Logs Speaking to You? BOF6540 - Java Champions and JUG Leaders Meet Oracle Executives (with Jeff Genender, Mattias Karlsson, Henrik Stahl, Georges Saab) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Ellen Kraffmiller Martijn Verburg, Jeff Genender, and Henri Tremblay) I asked him what technological changes need to be taken into account in performance tuning. “The volume of data we're dealing with just seems to be getting bigger and bigger all the time,” observed Pepperdine. “A couple of years ago you'd never think of needing a heap that was 64g, but today there are deployments where the heap has grown to 256g and tomorrow there are plans for heaps that are even larger. Dealing with all that data simply requires more horse power and some very specialized techniques. In some cases, teams are trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work -- let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one where if you were to even consider using a transaction, you've lost." When asked about the greatest misconceptions about performance tuning that he currently encounters, he said, “If you have a performance problem, you should start looking at code at the very least and for that extra step, whip out an execution profiler. I'm not going to say that I never use execution profilers or look at code. What I will say is that execution profilers are effective for a small subset of performance problems and code is literally the last thing you should look at.And what is the most exciting thing happening in the world of Java today? “Interesting question because so many people would say that nothing exciting is happening in Java. Some might be disappointed that a few features have slipped in terms of scheduling. But I'd disagree with the first group and I'm not so concerned about the slippage because I still see a lot of exciting things happening. First, lambda will finally be with us and with lambda will come better ways.” For JavaOne, he is proctoring for Heinz Kabutz's lab. “I'm actually looking forward to that more than I am to my own talk,” he remarked. “Heinz will be the third non-Sun/Oracle employee to present a lab and the first since Oracle began hosting JavaOne. He's got a great message. He's spent a ton of time making sure things are going to work, and we've got a great team of proctors to help out. After that, getting my talk done, the Java Champion's panel session and then kicking back and just meeting up and talking to some Java heads."Finally, what should Java developers know that they currently do not know? “’Write Once, Run Everywhere’ is a great slogan and Java has come closer to that dream than any other technology stack that I've used. That said, different hardware bits work differently and as hard as we try, the JVM can't hide all the differences. Plus, if we are to get good performance we need to work with our hardware and not against it. All this implies that Java developers need to know more about the hardware they are deploying to.” Originally published on blogs.oracle.com/javaone.

  • Making the most of next weeks SharePoint 2010 developer training

    - by Eric Nelson
    [you can still register if you are free on the afternoons of 9th to 11th – UK time] We have 50+ registrations with more coming in – which is fantastic. Please read on to make the most of the training. Background We have structured the training to make sure that you can still learn lots during the three days even if you do not have SharePoint 2010 installed. Additionally the course is based around a subset of the channel 9 training to allow you to easily dig deeper or look again at specific areas. Which means if you have zero time between now and next Wednesday then you are still good to go. But if you can do some pre-work you will likely get even more out of the three days. Step 1: Check out the topics and resources available on-demand The course is based around a subset of the channel 9 training to allow you to easily dig deeper or look again at specific areas. Take a lap around the SharePoint 2010 Training Course on Channel 9 Download the SharePoint Developer Training Kit Step 2: Use a pre-configured Virtual Machine which you can download (best start today – it is large!) Consider using the VM we created If you don't have access to SharePoint 2010. You will need a 64bit host OS and bare minimum of 4GB of RAM. 8GB recommended. Virtual PC can not be used with this VM – Virtual PC only supports 32bit guests. The 2010-7a Information Worker VM gives you everything you need to develop for SharePoint 2010. Watch the Video on how to use this VM Download the VM Remember you only need to download the “parts” for the 2010-7a VM. There are 3 subtly different ways of using this VM: Easiest is to follow the advice of the video and get yourself a host OS of Windows Server 2008 R2 with Hyper-V and simply use the VM Alternatively you can take the VHD and create a “Boot to VHD” if you have Windows 7 Ultimate or Enterprise Edition. This works really well – especially if you are already familiar with “Boot to VHD” (This post I did will help you get started) Or you can take the VHD and use an alternative VM tool such as VirtualBox if you have a different host OS. NB: This tends to involve some work to get everything running fine. Check out parts 1 to 3 from Rolly and if you go with Virtual Box use an IDE controller not SATA. SATA will blue screen. Note in the screenshot below I also converted the vhd to a vmdk. I used the FREE Starwind Converter to do this whilst I was fighting blue screens – not sure its necessary as VirtualBox does now work with VHDs. or Step 3 – Install SharePoint 2010 on a 64bit Windows 7 or Vista Host I haven’t tried this but it is now supported. Check out MSDN. Final notes: I am in the process of securing a number of hosted VMs for ISVs directly managed by my team. Your Architect Evangelist will have details once I have them! Else we can sort out on the Wed. Regrettably I am unable to give folks 1:1 support on any issues around Boot to VHD, 3rd party VM products etc. Related Links: Check you are fully plugged into the work of my team – have you done these simple steps including joining our new LinkedIn group?

  • New Working Environment Starting November

    - by Jenson
    Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 This is actually a post dated update. After I’ve been working in the private sectors for so many years (the 2 years when I was working as IT trainer in a secondary school is not counted, as I was working under a contract with a private IT training agency), I’ve decided to try my luck into public sector. And fortunately, I passed the interview and I was offered a position of Web Administrator in a government statutory board, that’s Agency for Science, Technology and Research (of Singapore). During my previous employment with a Japanese MNC (multinational company), it was a totally new environment for me, as I had never worked for a Japanese company before, but the first time I work for Japanese company also gave me the very first nightmare I have with them, and vowed not to work for them anymore, and any other Japanese companies. No doubt I have freedom of choosing the tools and methods I wish to use for the projects, but the project management is simply too messy and out of order. And a lot of time, I don’t find that everyone is working as a team, more like achieving their own goals. Accountability for project is not shared, all lumped onto the shoulders of the developer in charge (they called it Software Engineer). I was working on a windows based .NET project, which I already voiced out that it’s not manageable by just 1 software engineer, but it seems like nobody cares, even the one who propose the solution to customer doesn’t care much. What he cares is whether you deliver the project on time so that he can please his customer and the senior management of his good work. Too many stories to tell, and I just simple doesn’t want to talk too much on this as it has already became the past to me. With my new title with the government agency, I hope to contribute my best to them, while learning as much as I can. I will share whatever I can on technologies, methodologies, and etc whichever I’m allowed and permitted to (of course, for those non-work-related stuff, I would be glad to share with you without much hesitation). Thank you! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • How do you report out user research results?

    - by user12277104
    A couple weeks ago, one of my mentees asked to meet, because she wanted my advice on how to report out user research results. She had just conducted her first usability test for her new employer, and was getting to the point where she wanted to put together some slides, but she didn't want them to be boring. She wanted to talk with me about what to present and how best to present results to stakeholders. While I couldn't meet for another week, thanks to slideshare, I could quickly point her in the direction that my in-person advice would have led her. First, I'd put together a panel for the February 2012 New Hampshire UPA monthly meeting that we then repeated for the 2012 Boston UPA annual conference. In this panel, I described my reporting techniques, as did six of my colleagues -- two of whom work for companies smaller than mine, and four of whom are independent consultants. Before taking questions, we each presented for 3 to 5 minutes on how we presented research results. The differences were really interesting. For example, when do you really NEED a long, written report (as opposed to an email, spreadsheet, or slide deck with callouts)? When you are reporting your test results to the FDA -- that makes sense. in this presentation, I describe two modes of reporting results that I use.  Second, I'd been a participant in the CUE-9 study. CUE stands for Comparative Usability Evaluation, and this was the 9th of these studies that Rolf Molich had designed. Originally, the studies were designed to show the variability in evaluation methods practitioners use to evaluate websites and applications. Of course, using methods and tasks of their own choosing, the results were wildly different. However, in this 9th study, the tasks were the same, the participants were the same, and the problem severity scale was the same, so how would the results of the 19 practitioners compare? Still wildly variable. But for the purposes of this discussion, it gave me a work product that was not proprietary to the company I work for -- a usability test report that I could share publicly. This was the way I'd been reporting results since 2005, and pretty much what I still do, when time allows.  That said, I have been continuing to evolve my methods and reporting techniques, and sometimes, there is no time to create that kind of report -- the team can't wait the days that it takes to take screen shots, go through my notes, refer back to recordings, and write it all up. So in those cases, I use bullet points in email, talk through the findings with stakeholders in a 1-hour meeting, and then post the take-aways on a wiki page. There are other requirements for that kind of reporting to work -- for example, the stakeholders need to attend each of the sessions, and the sessions can't take more than a day to complete, but you get the idea: there is no one "right" way to report out results. If the method of reporting you are using is giving your stakeholders the information they need, in a time frame in which it is useful, and in a format that meets their needs (FDA report or bullet points on a wiki), then that's the "right" way to report your results.

  • Iterative and Incremental Principle Series 4: Iteration Planning – (a.k.a What should I do today?)

    - by llowitz
    Welcome back to the fourth of a five part series on applying the Iteration and Incremental principle.  During the last segment, we discussed how the Implementation Plan includes the number of the iterations for a project, but not the specifics about what will occur during each iteration.  Today, we will explore Iteration Planning and discuss how and when to plan your iterations. As mentioned yesterday, OUM prescribes initially planning your project approach at a high level by creating an Implementation Plan.  As the project moves through the lifecycle, the plan is progressively refined.  Specifically, the details of each iteration is planned prior to the iteration start. The Iteration Plan starts by identifying the iteration goal.  An example of an iteration goal during the OUM Elaboration Phase may be to complete the RD.140.2 Create Requirements Specification for a specific set of requirements.  Another project may determine that their iteration goal is to focus on a smaller set of requirements, but to complete both the RD.140.2 Create Requirements Specification and the AN.100.1 Prepare Analysis Specification.  In an OUM project, the Iteration Plan needs to identify both the iteration goal – how far along the implementation lifecycle you plan to be, and the scope of work for the iteration.  Since each iteration typically ranges from 2 weeks to 6 weeks, it is important to identify a scope of work that is achievable, yet challenging, given the iteration goal and timeframe.  OUM provides specific guidelines and techniques to help prioritize the scope of work based on criteria such as risk, complexity, customer priority and dependency.  In OUM, this prioritization helps focus early iterations on the high risk, architecturally significant items helping to mitigate overall project risk.  Central to the prioritization is the MoSCoW (Must Have, Should Have, Could Have, and Won’t Have) list.   The result of the MoSCoW prioritization is an Iteration Group.  This is a scope of work to be worked on as a group during one or more iterations.  As I mentioned during yesterday’s blog, it is pointless to plan my daily exercise in advance since several factors, including the weather, influence what exercise I perform each day.  Therefore, every morning I perform Iteration Planning.   My “Iteration Plan” includes the type of exercise for the day (run, bike, elliptical), whether I will exercise outside or at the gym, and how many interval sets I plan to complete.    I use several factors to prioritize the type of exercise that I perform each day.  Since running outside is my highest priority, I try to complete it early in the week to minimize the risk of not meeting my overall goal of doing it twice each week.  Regardless of the specific exercise I select, I follow the guidelines in my Implementation Plan by applying the 6-minute interval sets.  Just as in OUM, the iteration goal should be in context of the overall Implementation Plan, and the iteration goal should move the project closer to achieving the phase milestone goals. Having an Implementation Plan details the strategy of what I plan to do and keeps me on track, while the Iteration Plan affords me the flexibility to juggle what I do each day based on external influences thus maximizing my overall success. Tomorrow I’ll conclude the series on applying the Iterative and Incremental approach by discussing how to manage the iteration duration and highlighting some benefits of applying this principle.

  • Hardware wireless switch has no effect after suspend and 13.10 upgrade

    - by blaineh
    This seems to be a fairly chronic problem, as shown by the following questions: How do I fix a "Wireless is disabled by hardware switch" error? Wireless disabled by hardware switch "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this? but no good solutions have been found! Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. All My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A ip=155.99.215.79 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. xev shows that no internal event is triggered for my wireless switch (f12), but other function keys also acting as hardware switches work fine. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. I just tried to reload bios defaults (or something) as shown by this video. Didn't work. Edit. I tried the contents of this answer, and it didn't work. Edit. I made a pastebin of dmesg. I couldn't even begin to understand the contents. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

  • Don't Forget To Enjoy Life

    - by Justin
    I have a pretty clear stance on posting personal information in my blogs. I tend to avoid it almost instinctively. Part of that is because I am a somewhat private person. And the other is because I know how easy it is for personal information to be gathered and collected from sources such as blogs. So, this has remained a tech only blog for me. I've only posted topics mostly related to issues I have encountered at work. In a way this blog is a 'bookmark' for me. If I post something here and run into the issue again it allows me to refer back to a convenient place where the 'fix' is documented in a way that I understand. But today, I am posting something that speaks to everyone. Something PERSONAL. Honestly, I expect this entry to receive zero views. But if nothing else, I can come back to this blog one day when I'm having a bad day or something and run across this post. And I will be reminded... DON'T FORGET TO ENJOY LIFE. Say this to yourself out loud, right now. People, we can get caught up in some rather mundane details as we trek through life. It's so easy to lose track of what really matters that it should be no surprise to find yourself reading something like this and thinking to yourself 'Yeah. You are right, man. Some of this crap I'm clinging on to right now is so small in the grand scheme of things'. I have no reservation, no shame, in saying that I am more often than not caught up in the ever evolving world of 'shit that does not matter'. When you work in technology, you are surrounded by deadlines, upgrades, new versions, support 'end of life', etc. And by time you get done with your 8 hours you go home and put in a few more because you are STILL CAUGHT UP in the things you dealt with at work all day. DO YOURSELF A FAVOR. DO YOUR FAMILY AND FRIEND A FAVOR. When you are done for the day, and you drive home, get those work-related things out of your head before you pull into the driveway. If you are still thinking on them when you park the car, leave the engine running, close your eyes and take a deep breath. If you believe in God, pray. If you don't then meditate for a second with the INTENTION of letting go of the day and becoming the 'real you'. You may have forgotten who the real you is so I'll remind you.... THE REAL YOU IS THAT GUY OR GAL THAT LAUGHS, LOVES, AND LIVES. Be the real you as often as possible. If you can't do it during your 9 - 5, do it at home. YOUR RELATIONSHIPS AND YOUR PERSONAL HAPPINESS DEPEND ON IT. I am going to make you a promise right now. If you do what I've just said, your days will be longer and your joy will be exponential. I can't explain why I know this to be true. But I do know it. And if you are there reading this right now, you know it is true too. We both know it is true because it COMES FROM WITHIN EVERY MAN, WOMAN and CHILD. We are born into love and happiness. Lets not fade away into the darkness so easily found in this world. Lets keep the flame burning. The flame of passion. Passion for LIFE. Peace be with you.

  • Working and Studying in Oracle, how I balance my time....

    - by anca.rosu
    Hi, my name is Laura. I am working as an Intern within Executive Administration at Oracle Denmark, whilst studying Information Management at Copenhagen Business school. I have recently handeding a paper on Information Systems which gave me exposure to Oracle. Once completing this paper I came across a job posting on my University’s intranet site and I applied directly online. When I submitted my application for the job offer, I wondered about what language I should use for the application form, as the job posting was in Danish, but the contact person and number looked Irish. I therefore chose English. Later that same day, Fiona, one of Oracle’s Graduates Recruitment Consultants based in Ireland, contacted me. This shows how global Oracle truly is. I went for my face-to-face interview in Oracle Denmark with Charlotte, one of the team managers. I spent 5 minutes waiting in the lobby, just looking around, thinking to myself, I really want to work here. The atmosphere seemed so pleasant with a relaxed approach between colleagues, employees and guests. The interview took about an hour, but we touched on a lot of different subjects. The profile I got of Oraclewas that this is a place where you are encouraged to think for yourself, and you are given the freedom to use your ideas. Later that evening, Fiona called and offered me the job. I was very happy. At Oracle Denmark we have 4 different zones: a Quiet Zone, a Project Zone, a Dialogue Zone and a Call Zone. Everyday when you arrive you consider what will be the most productive for the day’s task, and you take your toolbox and go find a desk in the zone you have decided on. It is therefore very unusual to be next to the same person two days in a row. At Oracle, people are located all over the world, and everybody has team members, colleagues or leaders in other countries, or even other time zones. Initially,I was worried about how I would adapt to this approach but I soon realized I had nothing to worry about and now I appreciate working this way. My colleagues have been very supportive and they have openly welcomed me into my new role. I typically work two days a week and have three days at University. During exam periods, I have the flexibility to work less hours and focus on the exams, in return for putting in more hours at work when needed. The first time I had to ask for time off before handing in a paper, my boss looked at me and said, ”Of course! Your education is the most important!” I hope that by sharing my experiences with you, I can inspire or encourage you to consider Oracle as a potential employer, where you can grow both professionally and personally.

  • Future Of F# At Jazoon 2011

    - by Alois Kraus
    I was at the Jazoon 2011 in Zurich (Switzerland). It was a really cool event and it had many top notch speaker not only from the Microsoft universe. One of the most interesting talks was from Don Syme with the title: F# Today/F# Tomorrow. He did show how to use F# scripting to browse through open databases/, OData Web Services, Sharepoint, …interactively. It looked really easy with the help of F# Type Providers which is the next big language feature in a future F# version. The object returned by a Type Provider is used to access the data like in usual strongly typed object model. No guessing how the property of an object is called. Intellisense will show it just as you expect. There exists a range of Type Providers for various data sources where the schema of the stored data can somehow be dynamically extracted. Lets use e.g. a free database it would be then let data = DbProvider(http://.....); data the object which contains all data from e.g. a chemical database. It has an elements collection which contains an element which has the properties: Name, AtomicMass, Picture, …. You can browse the object returned by the Type Provider with full Intellisense because the returned object is strongly typed which makes this happen. The same can be achieved of course with code generators that use an input the schema of the input data (OData Web Service, database, Sharepoint, JSON serialized data, …) and spit out the necessary strongly typed objects as an assembly. This does work but has the downside that if the schema of your data source is huge you will quickly run against a wall with traditional code generators since the generated “deserialization” assembly could easily become several hundred MB. *** The following part contains guessing how this exactly work by asking Don two questions **** Q: Can I use Type Providers within C#? D: No. Q: F# is after all a library. I can reference the F# assemblies and use the contained Type Providers? D: F# does annotate the generated types in a special way at runtime which is not a static type that C# could use. The F# type providers seem to use a hybrid approach. At compilation time the Type Provider is instantiated with the url of your input data. The obtained schema information is used by the compiler to generate static types as usual but only for a small subset (the top level classes up to certain nesting level would make sense to me). To make this work you need to access the actual data source at compile time which could be a problem if you want to keep the actual url in a config file. Ok so this explains why it does work at all. But in the demo we did see full intellisense support down to the deepest object level. It looks like if you navigate deeper into the object hierarchy the type provider is instantiated in the background and attach to a true static type the properties determined at run time while you were typing. So this type is not really static at all. It is static if you define as a static type that its properties shows up in intellisense. But since this type information is determined while you are typing and it is not used to generate a true static type and you cannot use these “intellistatic” types from C#. Nonetheless this is a very cool language feature. With the plotting libraries you can generate expressive charts from any datasource within seconds to get quickly an overview of any structured data storage. My favorite programming language C# will not get such features in the near future there is hope. If you restrict yourself to OData sources you can use LINQPad to query any OData enabled data source with LINQ with ease. There you can query Stackoverflow with The output is also nicely rendered which makes it a very good tool to explore OData sources today.

  • Talking JavaOne with Rock Star Kirk Pepperdine

    - by Janice J. Heiss
    Kirk Pepperdine is not only a JavaOne Rock Star but a Java Champion and a highly regarded expert in Java performance tuning who works as a consultant, educator, and author. He is the principal consultant at Kodewerk Ltd. He speaks frequently at conferences and co-authored the Ant Developer's Handbook. In the rapidly shifting world of information technology, Pepperdine, as much as anyone, keeps up with what's happening with Java performance tuning. Pepperdine will participate in the following sessions: CON5405 - Are Your Garbage Collection Logs Speaking to You? BOF6540 - Java Champions and JUG Leaders Meet Oracle Executives (with Jeff Genender, Mattias Karlsson, Henrik Stahl, Georges Saab) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Ellen Kraffmiller Martijn Verburg, Jeff Genender, and Henri Tremblay) I asked him what technological changes need to be taken into account in performance tuning. “The volume of data we're dealing with just seems to be getting bigger and bigger all the time,” observed Pepperdine. “A couple of years ago you'd never think of needing a heap that was 64g, but today there are deployments where the heap has grown to 256g and tomorrow there are plans for heaps that are even larger. Dealing with all that data simply requires more horse power and some very specialized techniques. In some cases, teams are trying to push hardware to the breaking point. Under those conditions, you need to be very clever just to get things to work -- let alone to get them to be fast. We are very quickly moving from a world where everything happens in a transaction to one where if you were to even consider using a transaction, you've lost." When asked about the greatest misconceptions about performance tuning that he currently encounters, he said, “If you have a performance problem, you should start looking at code at the very least and for that extra step, whip out an execution profiler. I'm not going to say that I never use execution profilers or look at code. What I will say is that execution profilers are effective for a small subset of performance problems and code is literally the last thing you should look at.And what is the most exciting thing happening in the world of Java today? “Interesting question because so many people would say that nothing exciting is happening in Java. Some might be disappointed that a few features have slipped in terms of scheduling. But I'd disagree with the first group and I'm not so concerned about the slippage because I still see a lot of exciting things happening. First, lambda will finally be with us and with lambda will come better ways.” For JavaOne, he is proctoring for Heinz Kabutz's lab. “I'm actually looking forward to that more than I am to my own talk,” he remarked. “Heinz will be the third non-Sun/Oracle employee to present a lab and the first since Oracle began hosting JavaOne. He's got a great message. He's spent a ton of time making sure things are going to work, and we've got a great team of proctors to help out. After that, getting my talk done, the Java Champion's panel session and then kicking back and just meeting up and talking to some Java heads."Finally, what should Java developers know that they currently do not know? “’Write Once, Run Everywhere’ is a great slogan and Java has come closer to that dream than any other technology stack that I've used. That said, different hardware bits work differently and as hard as we try, the JVM can't hide all the differences. Plus, if we are to get good performance we need to work with our hardware and not against it. All this implies that Java developers need to know more about the hardware they are deploying to.”

  • Why We Do What We Do. (Part 3 of 5 Part Series on JDE 5G Postponed)

    - by Kem Butller-Oracle
    By Lyle Ekdahl - Oracle JD Edwards Sr. VP General Manager  In the closing of part two of this 5 part blog series, I stated that in the next installment I would explore the expected results of the digital overdrive era and the impact it will have on our economy. While I have full intentions of writing on that topic, I am inspired today to write about something that is top of mind. It’s top of mind because it has come up several times recently conversations with my Oracle’s JD Edwards team members, with customers and our partners, plus I feel passionately about why I do what I do…. It is not what we do but why we do that thing that we do Do you know what you do? For the most part, I bet you could tell me what you do even if your work has changed over the years.  My real question is, “Do you get excited about what you do, and are you fulfilled? Does your work deliver a sense of purpose, a cause to work for, and something to believe in?”  Alright, I guess that was not a single question. So let me just ask, “Why?” Why are you here, right now? Why do you get up in the morning? Why do you go to work? Of course, I can’t answer those questions for you but I can share with you my POV.   For starters, there are several things that drive me. As many of you know by now, I have a somewhat competitive nature but it is not solely the thrill of winning that actually fuels me. Now don’t get me wrong, I do like winning occasionally. However winning is only a potential result of competing and is clearly not guaranteed. So why compete? Why compete in business, and particularly why in this Enterprise Software business?  Here’s why! I am fascinated by creative and building processes. It is about making or producing things, causing something to come into existence. With the right skill, imagination and determination, whether it’s art or invention; the result can deliver value and inspire. In both avocation and vocation I always gravitate towards the create/build processes.  I believe one of the skills necessary for the create/build process is not just the aptitude but also, and especially, the desire and attitude that drives one to gain a deeper understanding. The more I learn about our customers, the more I seek to understand what makes the successful and what difficult issues cause them to struggle. I like to look for the complex, non-commodity process problems where streamlined design and modern technology can provide an easy and simple solution. It is especially gratifying to see our customers use our software to increase their own ability to deliver value to the market. What an incredible network effect! I know many of you share this customer obsession as well as the create/build addiction focused on simple and elegant design. This is what I believe is at the root of our common culture.  Are JD Edwards customers on a whole different than other ERP solutions’ customers? I would argue that for the most part, yes, they are. They selected our software, and our software is different. Why? Because I believe that the create/build process will generally result in solutions that reflect who built it and their culture. And a culture of people focused on why they create/build will attract different customers than one that is based on what is built or how the solution is delivered. In the past I have referred to this idea as character of the customer, and it transcends industry, size and run rate. Now some would argue that JD Edwards has some customers who are characters. But that is for a different post. As I have told you before, the JD Edwards culture is unique, and its resulting economy is valuable and deserving of our best efforts.

  • My collection of favourite TFS utilities

    - by Aaron Kowall
    So, you’re in charge of your company or team’s Team Foundation Server.  Wish it was easier to manage, administer, extend?  Well, here are a few utilities that I highly recommend looking at. I’ve recently had need to rebuild my laptop and upgrade my local TFS environment to TFS 2012 Update 1.  This gave me cause to enumerate some of the utilities I like to have on hand. One of the reasons I love to use TFS on projects is that it’s basically a complete ALM toolkit.  Everything from Task Management, Version Control, Build Management, Test Management, Metrics and Reporting are all there ‘in the box’.  However, no matter how complete a product set it, there are always ways to make it better.  Here are a list of utilities and libraries that are pretty generally useful.  this is not intended to be an exhaustive list of TFS extensions but rather a set that I recommend you look at.  There are many more out there that may be applicable in one scenario or another.  This set of tools should work with TFS 2012 or 2010 if you grab the right version. Most of these tools (and more) are available from the Visual Studio Gallery or CodePlex. General TFS Power Tools – This is ‘the’ collection of utilities and extensions delivered by the Product Group.  Highly recommended from here are the Best Practice Analyzer for ensuring your TFS implementation is healthy and the Team Foundation Server Backups to ensure your TFS databases are backed up correctly. TFS Administrators Toolkit – helps make updates to work item types and reports across many team projects.  Also provides visibility of disk usage by finding large files in version control or test attachments to assist in managing storage utilization. Version Control Git-TF - a set of cross-platform, command line tools that facilitate sharing of changes between TFS and Git. These tools allow a developer to use a local Git repository, and configure it to share changes with a TFS server.  Great for all Git lovers who must integrate into a TFS repository. Testing TFS 2012 Tester Power Tool – A utility for bulk copying test cases which assists in an approach for managing test cases across multiple releases.  A little plug that this utility was written and maintained by Anna Russo of Imaginet where I also work. Test Scribe - A documentation power tool designed to construct documents directly from the TFS for test plan and test run artifacts for the purpose of discussion, reporting etc. Reporting Community TFS Report Extensions - a single repository of SQL Server Reporting Services report for Team Foundation 2010 (and above).  Check out the Test Plan Status report by Imaginet’s Steve St. Jean.  Very valuable for your test managers. Builds TFS Build Manager – A great utility if you are build manager over a complex build environment with many TFS build definitions. Community TFS Build Extensions – contains many custom build activities.  Current release binaries are for TFS 2010 but many of the activities can be recompiled for use with TFS 2012. While compiling this list, I was surprised by the number of TFS utilities and extensions I no longer use/need in TFS 2012 because of the great work by the TFS team addressing many gaps since the 2010 release. Are there any utilities you depend on that I’ve missed?  I’d love to hear about them in the comments!

  • Dont Throw Duplicate Exceptions

    In your code, youll sometimes have write code that validates input using a variety of checks.  Assuming you havent embraced AOP and done everything with attributes, its likely that your defensive coding is going to look something like this: public void Foo(SomeClass someArgument) { if(someArgument == null) { throw new InvalidArgumentException("someArgument"); } if(!someArgument.IsValid()) { throw new InvalidArgumentException("someArgument"); }   // Do Real Work } Do you see a problem here?  Heres the deal Exceptions should be meaningful.  They have value at a number of levels: In the code, throwing an exception lets the develop know that there is an unsupported condition here In calling code, different types of exceptions may be handled differently At runtime, logging of exceptions provides a valuable diagnostic tool Its this last reason I want to focus on.  If you find yourself literally throwing the exact exception in more than one location within a given method, stop.  The stack trace for such an exception is likely going to be identical regardless of which path of execution led to the exception being thrown.  When that happens, you or whomever is debugging the problem will have to guess which exception was thrown.  Guessing is a great way to introduce additional problems and/or greatly increase the amount of time require to properly diagnose and correct any bugs related to this behavior. Dont Guess Be Specific When throwing an exception from multiple code paths within the code, be specific.  Virtually ever exception allows a custom message use it and ensure each case is unique.  If the exception might be handled differently by the caller, than consider implementing a new custom exception type.  Also, dont automatically think that you can improve the code by collapsing the if-then logic into a single call with short-circuiting (e.g. if(x == null || !x.IsValid()) ) that will guarantee that you cant easily throw different information into the message as easily as constructing the exception separately in each case. The code above might be refactored like so:   public void Foo(SomeClass someArgument) { if(someArgument == null) { throw new ArgumentNullException("someArgument"); } if(!someArgument.IsValid()) { throw new InvalidArgumentException("someArgument"); }   // Do Real Work } In this case its taking advantage of the fact that there is already an ArgumentNullException in the framework, but if you didnt have an IsValid() method and were doing validation on your own, it might look like this: public void Foo(SomeClass someArgument) { if(someArgument.Quantity < 0) { throw new InvalidArgumentException("someArgument", "Quantity cannot be less than 0. Quantity: " + someArgument.Quantity); } if(someArgument.Quantity > 100) { throw new InvalidArgumentException("someArgument", "SomeArgument.Quantity cannot exceed 100. Quantity: " + someArgument.Quantity); }   // Do Real Work }   Note that in this last example, Im throwing the same exception type in each case, but with different Message values.  Im also making sure to include the value that resulted in the exception, as this can be extremely useful for debugging.  (How many times have you wished NullReferenceException would tell you the name of the variable it was trying to reference?) Dont add work to those who will follow after you to maintain your application (especially since its likely to be you).  Be specific with your exception messages follow DRY when throwing exceptions within a given method by throwing unique exceptions for each interesting case of invalid state. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Rotation of viewplatform in Java3D

    - by user29163
    I have just started with Java3D programming. I thought I had built up some basic intuition about how the scene graph works, but something that should work, does not work. I made a simple program for rotating a pyramid around the y-axis. This was done just by adding a RotationInterpolator R to the TransformGroup above the pyramid. Then I thought hey, can I now remove the RotationInterpolator from this TransformGroup, then add it to the TransformGroup above my ViewPlatform leaf. This should work if I have understood how things work. Adding the RotationInterpolator to this TransformGroup, should make the children of this TransformGroup rotate, and the ViewingPlatform is a child of the TransformGroup. Any ideas on where my reasoning is flawed? Here is the code for setting up the universe, and the view branchgroup. import java.awt.*; import java.awt.event.*; import javax.media.j3d.*; import javax.vecmath.*; public class UniverseBuilder { // User-specified canvas Canvas3D canvas; // Scene graph elements to which the user may want access VirtualUniverse universe; Locale locale; TransformGroup vpTrans; View view; public UniverseBuilder(Canvas3D c) { this.canvas = c; // Establish a virtual universe that has a single // hi-res Locale universe = new VirtualUniverse(); locale = new Locale(universe); // Create a PhysicalBody and PhysicalEnvironment object PhysicalBody body = new PhysicalBody(); PhysicalEnvironment environment = new PhysicalEnvironment(); // Create a View and attach the Canvas3D and the physical // body and environment to the view. view = new View(); view.addCanvas3D(c); view.setPhysicalBody(body); view.setPhysicalEnvironment(environment); // Create a BranchGroup node for the view platform BranchGroup vpRoot = new BranchGroup(); // Create a ViewPlatform object, and its associated // TransformGroup object, and attach it to the root of the // subgraph. Attach the view to the view platform. Transform3D t = new Transform3D(); Transform3D s = new Transform3D(); t.set(new Vector3f(0.0f, 0.0f, 10.0f)); t.rotX(-Math.PI/4); s.set(new Vector3f(0.0f, 0.0f, 10.0f)); //forandre verdier her for å endre viewing position t.mul(s); ViewPlatform vp = new ViewPlatform(); vpTrans = new TransformGroup(t); vpTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE); // Rotator stuff Transform3D yAxis = new Transform3D(); //yAxis.rotY(Math.PI/2); Alpha rotationAlpha = new Alpha( -1, Alpha.INCREASING_ENABLE, 0, 0,4000, 0, 0, 0, 0, 0); RotationInterpolator rotator = new RotationInterpolator( rotationAlpha, vpTrans, yAxis, 0.0f, (float) Math.PI*2.0f); RotationInterpolator rotator2 = new RotationInterpolator( rotationAlpha, vpTrans); BoundingSphere bounds = new BoundingSphere(new Point3d(0.0,0.0,0.0), 1000.0); rotator.setSchedulingBounds(bounds); vpTrans.addChild(rotator); vpTrans.addChild(vp); vpRoot.addChild(vpTrans); view.attachViewPlatform(vp); // Attach the branch graph to the universe, via the // Locale. The scene graph is now live! locale.addBranchGraph(vpRoot); } public void addBranchGraph(BranchGroup bg) { locale.addBranchGraph(bg); } }

  • libgdx draw issue and animation

    - by johnny-b
    it seems as though i cannot get the draw method to work??? it seems as though the bullet.draw(batcher) does not work and i cannot understand why as the bullet is a sprite. i have made a Sprite[] and added them as animation. could that be it? i tried batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY(), bullet.getOriginX() / 2, bullet.getOriginY() / 2, bullet.getWidth(), bullet.getHeight(), 1, 1, bullet.getRotation()); but that dont work, the only way it draws is this batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY()); below is the code. // this is in a Asset Class texture = new Texture(Gdx.files.internal("SpriteN1.png")); texture.setFilter(TextureFilter.Nearest, TextureFilter.Nearest); bullet1 = new Sprite(texture, 380, 350, 45, 20); bullet1.flip(false, true); bullet2 = new Sprite(texture, 425, 350, 45, 20); bullet2.flip(false, true); Sprite[] bullets = { bullet1, bullet2 }; bulletAnimation = new Animation(0.06f, bullets); bulletAnimation.setPlayMode(Animation.PlayMode.LOOP); // this is the GameRender class public class GameRender() { private Bullet bullet; private Ball ball; public GameRenderer(GameWorld world) { myWorld = world; cam = new OrthographicCamera(); cam.setToOrtho(true, 480, 320); batcher = new SpriteBatch(); // Attach batcher to camera batcher.setProjectionMatrix(cam.combined); shapeRenderer = new ShapeRenderer(); shapeRenderer.setProjectionMatrix(cam.combined); // Call helper methods to initialize instance variables initGameObjects(); initAssets(); } private void initGameObjects() { ball = GameWorld.getBall(); bullet = myWorld.getBullet(); scroller = myWorld.getScroller(); } private void initAssets() { ballAnimation = AssetLoader.ballAnimation; bulletAnimation = AssetLoader.bulletAnimation; } public void render(float runTime) { Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT); batcher.begin(); // Disable transparency // This is good for performance when drawing images that do not require // transparency. batcher.disableBlending(); // The ball needs transparency, so we enable that again. batcher.enableBlending(); batcher.draw(AssetLoader.ballAnimation.getKeyFrame(runTime), ball.getX(), ball.getY(), ball.getWidth(), ball.getHeight()); batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY()); // End SpriteBatch batcher.end(); } } // this is the gameworld class public class GameWorld { public static Ball ball; private Bullet bullet; private ScrollHandler scroller; public GameWorld() { ball = new Ball(480, 273, 32, 32); bullet = new Bullet(10, 10); scroller = new ScrollHandler(0); } public void update(float delta) { ball.update(delta); bullet.update(delta); scroller.update(delta); } public static Ball getBall() { return ball; } public ScrollHandler getScroller() { return scroller; } public Bullet getBullet() { return bullet; } } is there anyway so make the sprite work?

  • Fast Data - Big Data's achilles heel

    - by thegreeneman
    At OOW 2013 in Mark Hurd and Thomas Kurian's keynote, they discussed Oracle's Fast Data software solution stack and discussed a number of customers deploying Oracle's Big Data / Fast Data solutions and in particular Oracle's NoSQL Database.  Since that time, there have been a large number of request seeking clarification on how the Fast Data software stack works together to deliver on the promise of real-time Big Data solutions.   Fast Data is a software solution stack that deals with one aspect of Big Data, high velocity.   The software in the Fast Data solution stack involves 3 key pieces and their integration:  Oracle Event Processing, Oracle Coherence, Oracle NoSQL Database.   All three of these technologies address a high throughput, low latency data management requirement.   Oracle Event Processing enables continuous query to filter the Big Data fire hose, enable intelligent chained events to real-time service invocation and augments the data stream to provide Big Data enrichment. Extended SQL syntax allows the definition of sliding windows of time to allow SQL statements to look for triggers on events like breach of weighted moving average on a real-time data stream.    Oracle Coherence is a distributed, grid caching solution which is used to provide very low latency access to cached data when the data is too big to fit into a single process, so it is spread around in a grid architecture to provide memory latency speed access.  It also has some special capabilities to deploy remote behavioral execution for "near data" processing.   The Oracle NoSQL Database is designed to ingest simple key-value data at a controlled throughput rate while providing data redundancy in a cluster to facilitate highly concurrent low latency reads.  For example, when large sensor networks are generating data that need to be captured while analysts are simultaneously extracting the data using range based queries for upstream analytics.  Another example might be storing cookies from user web sessions for ultra low latency user profile management, also leveraging that data using holistic MapReduce operations with your Hadoop cluster to do segmented site analysis.  Understand how NoSQL plays a critical role in Big Data capture and enrichment while simultaneously providing a low latency and scalable data management infrastructure thru clustered, always on, parallel processing in a shared nothing architecture. Learn how easily a NoSQL cluster can be deployed to provide essential services in industry specific Fast Data solutions. See these technologies work together in a demonstration highlighting the salient features of these Fast Data enabling technologies in a location based personalization service. The question then becomes how do these things work together to deliver an end to end Fast Data solution.  The answer is that while different applications will exhibit unique requirements that may drive the need for one or the other of these technologies, often when it comes to Big Data you may need to use them together.   You may have the need for the memory latencies of the Coherence cache, but just have too much data to cache, so you use a combination of Coherence and Oracle NoSQL to handle extreme speed cache overflow and retrieval.   Here is a great reference to how these two technologies are integrated and work together.  Coherence & Oracle NoSQL Database.   On the stream processing side, it is similar as with the Coherence case.  As your sliding windows get larger, holding all the data in the stream can become difficult and out of band data may need to be offloaded into persistent storage.  OEP needs an extreme speed database like Oracle NoSQL Database to help it continue to perform for the real time loop while dealing with persistent spill in the data stream.  Here is a great resource to learn more about how OEP and Oracle NoSQL Database are integrated and work together.  OEP & Oracle NoSQL Database.

  • Making it GREAT! Oracle Partners Building Apps Workshop with UX and ADF in UK

    - by ultan o'broin
    Yes, making is what it's all about. This time, Oracle Partners in the UK were making great looking usable apps with the Oracle Applications Development Framework (ADF) and user experience (UX) toolkit. And what an energy-packed and productive event at the Oracle UK, Thames Valley Park, location it was. Partners learned the fundamentals of enterprise applications UX, why it's important, all about visual design, how to wireframe designs, and then how to build their already-proven designs in ADF. There was a whole day on mobile apps, learning about mobile design principles, free mobile UX and ADF resources from Oracle, and then trying it out. The workshop wrapped up with the latest Release 7 simplified UIs, Mobilytics, and other innovations from Oracle, and a live demo of a very neat ADF Mobile Android app built by an Oracle contractor. And, what a fun two days both Grant Ronald of ADF and myself had in running the workshop with such a great audience, too! I particularly enjoyed the wireframing and visual design sessions interaction; and seeing some outstanding work done by partners. Of note from the UK workshop were innovative design features not seen before and made me all the happier that developers were bringing their own ideas from the consumer IT world of mobility, simplicity, and social to the world of work apps in a smart way within an enterprise methodology too.  Partner wireframe exercise. Applying mobile design principles and UX design patterns means you've already productively making great usable apps! Next, over to Oracle ADF Mobile with it! One simple example from the design of a mobile field service app was that participants immediately saw how the UX and device functionality of the super UK-based app Hailo app could influence their designs (the London cabbie influence maybe?), as well as how we all use maps, cameras, barcode scanners and microphones on our phones could be used in work. And, of course, ADF Mobile has the device integration solutions there too! I wonder will U.S. workshops in Silicon Valley see an Uber UX influence (LOL)! That we also had partners experienced with Oracle Forms who could now offer a roadmap from Forms to Simplified UI and Mobile using ADF, and do it through through the cloud, really made this particular workshop go "ZING!" for me. Many thanks to the Oracle PartnerNetwork (OPN) team for organizing this event with us, and to the representatives of the Oracle Partners that showed and participated so well. That's what I love out this outreach. It's a two-way, solid value-add for all. Interested? Why would partners and developers with ADF skills sign up for this workshop? Here's why: Learn to use the Oracle Applications User Experience design patterns as the usability building blocks for applications development in Oracle Application Development Framework. The workshop enables attendees to build modern and visually compelling desktop and mobile applications that look and behave like Oracle Cloud Applications, and that can co-exist with partner integrations, new, or existing applications deployments. Partners learn to offer customers and clients more than just coded functionality; instead they can provide a complete user experience with a roadmap for continued ROI from applications that also creating more business and attracts the kudos and respect from other makers of apps as they're wowed by the results. So, if you're a partner and interested in attending one of these workshops and benefitting from such learning, as well as having a platform to show off some of your own work, stay well tuned to your OPN channels, to this blog, to the VoX blog, and to the @usableapps Twitter account too.

  • Managing software projects - advice needed

    - by Callum
    I work for a large government department as part of an IT team that manages and develops websites as well as stand alone web applications. We’re running in to problems somewhere in the SDLC that don’t rear their ugly head until time and budget are starting to run out. We try to be “Agile” (software specifications are not as thorough as possible, clients have direct access to the developers any time they want) and we are also in a reasonably peculiar position in that we are not allowed to make profit from the services we provide. We only service the divisions within our government department, and can only charge for the time and effort we actually put in to a project. So if we deliver a project that we have over-quoted on, we will only invoice for the actual time spent. Our software specifications are not as thorough as they could be, but they always include at a minimum: Wireframe mockups for every form view A data dictionary of all field inputs Descriptions of any business rules that affect the system Descriptions of the outputs I’m new to software management, but I’ve overseen enough software projects now to know that as soon as users start observing demos of the system, they start making a huge amount of requests like “Can we add a few more fields to this report.. can we redesign the look of this interface.. can we send an email at this part of the workflow.. can we take this button off this view.. can we make this function redirect to a different screen.. can we change some text on this screen… can we create a special account where someone can log in and get access to X… this report takes too long to run can it be optimised.. can we remove this step in the workflow… there’s got to be a better image we can put here…” etc etc etc. Some changes are tiny and can be implemented reasonably quickly.. but there could be up to 50-100 or so of such requests during the course of the SDLC. Other change requests are what clients claim they “just assumed would be part of the system” even if not explicitly spelled out in the spec. We are having a lot of difficulty managing this process. With no experienced software project managers in our team, we need to come up with a better way to both internally identify whether work being requested is “out of spec”, and be able to communicate this to a client in such a manner that they can understand why what they are asking for is “extra” work. We need a way to track this work and be transparent with it. In the spirit of Agile development where we are not spec'ing software systems in to the ground and back again before development begins, and bearing in mind that clients have access to any developer any time they want it, I am looking for some tips and pointers from experienced software project managers on how to handle this sort of "scope creep" problem, in tracking it, being transparent with it, and communicating it to clients such that they understand it. Happy to clarify anything as needed. I really appreciate anyone who takes the time to offer some advice. Thanks.

  • Trouble rotating viewplatform in Java3D [closed]

    - by user29163
    I have just started with Java3D programming. I thought I had built up some basic intuition about how the scene graph works, but something that should work, does not work. I made a simple program for rotating a pyramid around the y-axis. This was done just by adding a RotationInterpolator R to the TransformGroup above the pyramid. Then I thought hey, can I now remove the RotationInterpolator from this TransformGroup, then add it to the TransformGroup above my ViewPlatform leaf. This should work if I have understood how things work. Adding the RotationInterpolator to this TransformGroup, should make the children of this TransformGroup rotate, and the ViewingPlatform is a child of the TransformGroup. Any ideas on where my reasoning is flawed? Here is the code for setting up the universe, and the view branchgroup. import java.awt.*; import java.awt.event.*; import javax.media.j3d.*; import javax.vecmath.*; public class UniverseBuilder { // User-specified canvas Canvas3D canvas; // Scene graph elements to which the user may want access VirtualUniverse universe; Locale locale; TransformGroup vpTrans; View view; public UniverseBuilder(Canvas3D c) { this.canvas = c; // Establish a virtual universe that has a single // hi-res Locale universe = new VirtualUniverse(); locale = new Locale(universe); // Create a PhysicalBody and PhysicalEnvironment object PhysicalBody body = new PhysicalBody(); PhysicalEnvironment environment = new PhysicalEnvironment(); // Create a View and attach the Canvas3D and the physical // body and environment to the view. view = new View(); view.addCanvas3D(c); view.setPhysicalBody(body); view.setPhysicalEnvironment(environment); // Create a BranchGroup node for the view platform BranchGroup vpRoot = new BranchGroup(); // Create a ViewPlatform object, and its associated // TransformGroup object, and attach it to the root of the // subgraph. Attach the view to the view platform. Transform3D t = new Transform3D(); Transform3D s = new Transform3D(); t.set(new Vector3f(0.0f, 0.0f, 10.0f)); t.rotX(-Math.PI/4); s.set(new Vector3f(0.0f, 0.0f, 10.0f)); //forandre verdier her for å endre viewing position t.mul(s); ViewPlatform vp = new ViewPlatform(); vpTrans = new TransformGroup(t); vpTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE); // Rotator stuff Transform3D yAxis = new Transform3D(); //yAxis.rotY(Math.PI/2); Alpha rotationAlpha = new Alpha( -1, Alpha.INCREASING_ENABLE, 0, 0,4000, 0, 0, 0, 0, 0); RotationInterpolator rotator = new RotationInterpolator( rotationAlpha, vpTrans, yAxis, 0.0f, (float) Math.PI*2.0f); RotationInterpolator rotator2 = new RotationInterpolator( rotationAlpha, vpTrans); BoundingSphere bounds = new BoundingSphere(new Point3d(0.0,0.0,0.0), 1000.0); rotator.setSchedulingBounds(bounds); vpTrans.addChild(rotator); vpTrans.addChild(vp); vpRoot.addChild(vpTrans); view.attachViewPlatform(vp); // Attach the branch graph to the universe, via the // Locale. The scene graph is now live! locale.addBranchGraph(vpRoot); } public void addBranchGraph(BranchGroup bg) { locale.addBranchGraph(bg); } }

  • Profiling Startup Of VS2012 &ndash; dotTrace Profiler

    - by Alois Kraus
    Jetbrains which is famous for the Resharper tool has also a profiler in its portfolio. I downloaded dotTrace 5.2 Professional (569€+VAT) to check how far I can profile the startup of VS2012. The most interesting startup option is “.NET Process”. With that you can profile the next started .NET process which is very useful if you want to profile an application which is not started by you.     I did select Tracing as and Wall time to get similar options across all profilers. For some reason the attach option did not work with .NET 4.5 on my home machine. But I am sure that it did work with .NET 4.0 some time ago. Since we are profiling devenv.exe we can also select “Standalone Application” and start it from the profiler. The startup time of VS does increase about a factor 3 but that is ok. You get mainly three windows to work with. The first one shows the threads where you can drill down thread wise where most time is spent. I The next window is the call tree which does merge all threads together in a similar view. The last and most useful view in my opinion is the Plain List window which is nearly the same as the Method Grid in Ants Profiler. But this time we do get when I enable the Show system functions checkbox not a 150 but 19407 methods to choose from! I really tried with Ants Profiler to find something about out how VS does work but look how much we were missing! When I double click on a method I do get in the lower pane the called methods and their respective timings. This is something really useful and I can nicely drill down to the most important stuff. The measured time seems to be Wall Clock time which is a good thing to see where my time is really spent. You can also use Sampling as profiling method but this does give you much less information. Except for getting a first idea where to look first this profiling mode is not very useful to understand how you system does interact.   The options have a good list of presets to hide by default many method and gray them out to concentrate on your code. It does not filter anything out if you enable Show system functions. By default methods from these assemblies are hidden or if the checkbox is checked grayed out. All in all JetBrains has made a nice profiler which does show great detail and it has nice drill down capabilities. The only thing is that I do not trust its measured timings. I did fall several times into the trap with this one to optimize at places which were already fast but the profiler did show high times in these methods. After measuring with Tracing I was certain that the measured times were greatly exaggerated. Especially when IO is involved it seems to have a hard time to subtract its own overhead. What I did miss most was the possibility to profile not only the next started process but to be able to select a process by name and perhaps a count to profile the next n processes of this name.

  • Review: Windows 8 - Initial Experience

    - by Tim Murphy
    I originally started this post when I had the Windows 8 preview setup on VirtualBox image.  I have since put the RTM bits on a Dell E6530 that is my new work laptop.  It isn’t a table so I am not getting the touch experience, but as a developer this makes the most sense for the moment. This is the first Windows OS that I have had to spend much time exploring to even get started.  The first thing I ran into was when I clicked on the desktop icon I was lost.  Where is the Start menu? Where are my programs?  How do I get back to the Metro environment?  I finally tried hitting the Windows button and it popped back out to the Metro screen. Once I got past that I found that the look of the Metro interface is clean and well organized.  It should be familiar to anyone who is already using a Zune or Windows Phone 7.  In the Desktop, aside from the lack of the Start button to bring up programs the desktop is just like the Windows 7 environment we are all used to.  I do have to say though that I don’t like popping out to the Metro screen to find program.  I think installers for programs like ones that developers usually work in for a desktop mode will need to give an option for creating a desktop icon and pinning to the task bar of the desktop. One of the things I do really enjoy is having live tiles in the Metro environment.  It is a nice way of feeding my need for constant information.  The one drawback though is that the task bar at the bottom of my screen used to be where I got this information without leaving what I was working on.  It allowed me to see current temperatures and when there were messages waiting.  I have since found that these still work as expected in the Desktop and Toast message keep you up on what is going on in the Metro apps. Thankfully familiar functionality like Alt-Tab and Windows-Tab still work regardless of if apps are in the Metro or the Desktop environment.  Add to this the ability to find any application on the Metro screen by simply typing and things get very comfortable. I also started exploring some of the apps.  If you want see a ton of stats on your team at a glance check out the Sports app.  What games are coming up? Who are the leaders in a number of stats?  The Weather and Finance apps have good features as well and I am sure they will improve as users supply feedback. I have had to install Visual Studio 2010 side-by-side with VS2012 because the Windows Phone 7 SDK would only install on VS2010.  This isn’t a Windows 8 issue per se, but something that you need to be aware of if you are a developer moving to the new ecosystem. The overall experience is a joy despite a few hiccups.  For anyone moving to Windows 8 in on a non-touch laptop or desktop I do suggest this list of keyboard shortcuts.  Enjoy. del.icio.us Tags: Windows 8,Win8,Metro,Review

  • Squibbly: LibreOffice Integration Framework for the Java Desktop

    - by Geertjan
    Squibbly is a new framework for Java desktop applications that need to integrate with LibreOffice, or more generally, need office features as part of a Java desktop solution that could include, for example, JavaFX components. Here's what it looks like, right now, on Ubuntu 13.04: Why is the framework called Squibbly? Because I needed a unique-ish name, because "squibble" sounds a bit like "scribble" (which is what one does with text documents, etc), and because of the many absurd definitions in the Urban Dictionary for the apparently real word "squibble", e.g., "A name for someone who is squibblish in nature." And, another e.g., "A squibble is a small squabble. A squabble is a little skirmish." But the real reason is the first definition (and definitely not the fourth definition): "Taking a small portion of another persons something, such as a small hit off of a pipe, a bite of food, a sip of a drink, or drag of a cigarette." In other words, I took (or "squibbled") a small portion of LibreOffice, i.e., OfficeBean, and integrated it into a NetBeans Platform application. Now anyone can add new features to it, to do anything they need, such as create a legislative software system as Propylon has done with their own solution on the NetBeans Platform: For me, the starting point was Chuk Munn Lee's similar solution from some years ago. However, he uses reflection a lot in that solution, because he didn't want to bundle the related JARs with the application. I understand that benefit but I find it even more beneficial to not need to require the user to specify the location of the LibreOffice location, since all the necessary JARs and native libraries (currently 32-bit Linux only, by the way) are bundled with the application. Plus, hundreds of lines of reflection code, as in Chuk's solution, is not fun to work with at all. Switching between applications is done like this: It's a work in progress, a proof of concept only. Just the result of a few hours of work to get the basic integration to work. Several problems remain, some of them potentially unsolvable, starting with these, but others will be added here as I identify them: Window management problems. I'd like to let the user have multiple LibreOffice applications and documents open at the same time, each in a new TopComponent. However, I haven't figured out how to do that. Right now, each application is opened into the same TopComponent, replacing the currently open application. I don't know the OfficeBean API well enough, e.g., should a single OfficeBean be shared among multiple TopComponents or should each of them have their own instance of it? Focus problems. When putting the application behind other applications and then switching back to the application, typing text becomes impossible. When closing a TopComponent and reopening it, the content is lost completely. Somehow the loss of focus, and then the return of focus, disables something. No idea how to fix that. The project is checked into this location, which isn't public yet, so you can't access it yet. Once it's publicly available, it would be great to get some code contributions and tweaks, etc. https://java.net/projects/squibbly Here's the source structure, showing especially how the OfficeBean JARs and native libraries (currently for Linux 32-bit only) fit in: Ultimately, would be cool to integrate or share code with http://joeffice.com!
