  • Java EE/GlassFish Adoption Story by Kerry Wilson/Vanderbilt University

    - by reza_rahman
    Kerry Wilson is a Software Engineer at the Vanderbilt University Medical Center. He served in a consultant role to design a lightweight systems integration solution for the next generation Foundations Recovery Network using GlassFish, Java EE 6, JPA, @Scheduled EJBs, CDI, JAX-RS and JSF. He lives in Nashville, TN where he helps organize the Nashville Java User Group. Kerry shared his Java EE/GlassFish adoption story at the JavaOne 2013 Sunday GlassFish community event - check out the video below: Here is the slide deck for his talk: GlassFish Story by Kerry Wilson/Vanderbilt University Medical Center from glassfish Kerry outlined some of the details of the implementation and emphasized the fact that Java EE can be a great solution for applications that are considered small/lightweight. He mentioned the productivity gains through the modern Java EE programming model centered on annotations, POJOs and zero-configuration - comparing it with competing frameworks that aim towards similar productivity for lightweight applications. Kerry also stressed the quality of the excellent NetBeans integration with GlassFish and the need for community self-support in free, non-commercial open source projects like GlassFish.

  • Vertex Normals, Loading Mesh Data

    - by Ramon Johannessen
    My test FBX mesh is a cube. From what I surmise, it seems that the cube is on the extreme end of this issue, but I believe that the same issue would be able to occur in any mesh: Each vertex has 3 normals, each pointing a different direction. Of course loading in any type of mesh, potentially ones having thousands of vertices, I need to use indices and not duplicate shared verts. Currently, I'm just writing the normals to the vertex at the index that the FBX data tells me they go to, which has the effect of overwriting any previous normal data. But for lighting calculations I need more info, something that's equivalent to a normal per face, but I have no idea how this should be done. Do I average the 3 different verts' normals together or what?

  • How does landscape calculate free memory?

    - by David Planella
    I'm trying to debug an OOM situation in an Ubuntu 12.04 server, and looking at the Memory graphs in Landscape, I noticed that there wasn't any serious memory usage spike spike. Then I looked at the output of the free command and I wasn't quite sure how both memory usage results relate to each other. Here's landscape's output on the server: $ landscape-sysinfo System load: 0.0 Processes: 93 Usage of /: 5.6% of 19.48GB Users logged in: 1 Memory usage: 26% IP address for eth0: - Swap usage: 2% Then I run the free command and I get: $ free -m total used free shared buffers cached Mem: 486 381 105 0 4 165 -/+ buffers/cache: 212 274 Swap: 255 7 248 I can understand the 2% swap usage, but where does the 26% memory usage come from?

  • How can videos from Ubuntu drive appear on web page and play in an embedded Flash Player?

    - by nLinked
    I have a shared folder on Ubuntu Server 12.04. Users drop videos in. Ubuntu runs a Cron task to convert them to FLV format and put them into another folder. All I would like is a simple web page that displays all the files in that folder as links, and when you click on the link for the video you want to play, it should play in the same web page inside an embedded Flash/SWF player. Sounds really basic but I'm actually struggling to find a simple solution. Any thoughts appreciated!

  • It is possible to hibernate an LXC container?

    - by Jo-Erlend Schinstad
    I know about lxc-freeze and lxc-unfreeze, but as I understand it, these simply pauses the container, similar to sending SIGSTOP and SIGCONT to a process. If I reboot the host, then the containers will cease to exist, right? I would really like a way to save state to persistent storage so that I could resume them at some later time, even the host is rebooted or something like that. I can achieve exactly what I want using VirtualBox by using the "Save machine state" mechanism, but if I could do it with LXC, it would be completely awesome.

  • Creating Hosting Accounts in WHM on a Single IP

    - by Daniel Hanly
    I've just purchased a VPS with the hope of transferring multiple shared hosting accounts onto it. The problem is that I've only got 2 IP addresses with my VPS. I can create an account and assign it an IP address, but once I've done this once, I can't do it again. (1 IP address is my main root WHM IP, the other is my new hosting account IP). Can I create multiple hosting accounts and use the same IP? How would I manage multiple hosting accounts in this way? The domain for this hosting account has been purchased by the client, and they hold it (can't transfer for 60 days), so I need to adjust the DNS settings to redirect to my newly created hosting area - how can I do this without a dedicated IP address?

  • Building a virtualized SPARC environment

    - by Owen Allen
    If you're interested in making effective use of virtualization tools like Oracle VM Server, there's a whitepaper on oracle.com that you should check out. The whitepaper starts with a few specific technologies and hardware: Oracle VM Server for SPARC, T4 Servers, Ops Center, Solaris 11, Sun Network 10GbE Switches, and Sun ZFS Storage Appliances. It then explains how to use them to plan and set up a virtualized environment, in which guests are grouped in Server Pools with high availability and are managed through Ops Center. It explains how Ops Center simplifies the management of logical domains by using custom plans to create new logical domains and managing their life cycle through its user interface. So, if you're interested in setting up a cloud and you want to avoid surprises along the way, have a look.

  • File Transfer using RDP

    - by DesigningCode
    I often use RDP to log into servers.   A couple of issues I have had is that its a pain to get files onto the server from my PC at times, and, if there is something missing from the servers windows install, I can’t simply pop the DVD into remote server in some unknown location on the internet somewhere. The other day I was curious if RDP actually had anything…since it did support shared clipboards, so I went for a look through the options and low and behold, *hidden* away….. Select Options… Go to the “Local Resources” Tab, then where it has “Local devices and resources” it sneakily has a “More…” button. Which then displays a drive selection box.  Select the drive you want …. Then on your server you will get….. Nice.  That is useful.

  • Unable to get screen signal after purge FGLRX

    - by Boris
    I thought that my ATI driver was not running well so I wanted to re-instal it completely. I did: sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon and after a boot I wanted to intal the ATI driver BUT at the boot no more signal to my screen. Since, every time I turn on my PC it gets to purple screen and then screen shuts down ! Note that: Even if the screen is off, PC seems to be running almost well: I m still able to use my network to access data shared with NFS. Using live USB I have no screen problem. I tried to plug my screen on an alternative output but it did not work. I tried CTRL+ALT+F1 while being on purple screen but it does not do anything, screen shut down anyway. I m going to try the SHIFT thing and learn from blackscreen wiki...

  • Best practice to propagate preferences of application

    - by Shebuka
    What is your approach with propagation to all classes/windows of preferences/settings of your application? Do you share the preference_manager class to all classes/windows who need it or you make variables in each classes/windows and update them manually each time setting are changed? Currently I have a PreferencesInterface class that hold all preferences and is responsible to default all values with a dedicated method called on create and when needed, all values are public, so non getters/setters, also it have virtual SavePreferences/LoadPreferences methods. Then I have PreferencesManager that extends from PreferencesInterface and is responsible for actually implementation of SavePreferences/LoadPreferences. I've made this basically for cross-platform so that every platform can have a different implementation of actual storage (registry, ini, plist, xml, whatever).

  • Do I need to install a package (openSWAN or strongSWAN maybe) to use ipsec?

    - by user68886
    I want to connect to a windows share that only accepts ipsec transport mode. I have a list of security policies and a shared secret. I've skimmed through the man page on ipsec.conf on the web and it seems to be the place to put these polices. If ipsec is part of the kernel (and I think it is, I'm using Ubuntu 12.04) do I need to install some other package in order to get this working? I'm guessing it's either openSWAN or strongSWAN but don't know the difference.

  • Morgan Stanley chooses Solaris 11 to run cloud file services

    - by Frederic Pariente
    At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as it calls it in his blog. Mike used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Mike is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

  • T-SQL Tuesday - IO capacity planning

    - by Michael Zilberstein
    This post is my contribution to Adam Machanic's T-SQL Tuesday #004 , hosted this time by Mike Walsh . Being applicative DBA, I usually don't take part in discussions which storage to buy or how to configure it. My interaction with IO is usually via PerfMon. When somebody calls me asking why everything is suddenly so slow on database server, "disk queue length" or "average seconds per transfer" counters provide an overwhelming answer in 60-70% of such cases. Sometimes it can be...(read more)

  • Is data integrity possible without normalization?

    - by shuniar
    I am working on an application that requires the storage of location information such as city, state, zip code, latitude, and longitude. I would like to ensure: Location data is accurate Detroit, CA Detroit IS NOT in California Detroit, MI Detroit IS in Michigan Cities and states are spelled correctly California not Calefornia Detroit not Detriot Cities and states are named consistently Valid: CA Detroit Invalid: Cali california DET d-town The D Also, since city/zip data is not guaranteed to be static, updating this data in a normalized fashion could be difficult, whereas it could be implemented as a de facto location if it is denormalized. A couple thoughts that come to mind: A collection of reference tables that store a list of all states and the most common cities and zip codes that can grow over time. It would search the database for an exact or similar match and recommend corrections. Use some sort of service to validate the location data before it is stored in the database. Is it possible to fulfill these requirements without normalization, and if so, should I denormalize this data?

  • Whoosh: PASS Board Year 1, Q4

    - by Denise McInerney
    "Whoosh". That's the sound the last quarter of 2012 made as it rushed by. My first year on the PASS Board is complete, and the last three months of it were probably the busiest. PASS Summit 2012 Much of October was devoted to preparing for Summit. Every Board  member, HQ staffer and dozens of volunteers were busy in the run-up to our flagship event. It takes a lot of work to put on the Summit. The community meetings,  first-timers program, keynotes, sessions and that fabulous Community Appreciation party are the result of many hours of preparation. Virtual Chapters at the Summit With a lot of help from Karla Landrum, Michelle Nalliah, Lana Montgomery and others at HQ the VCs had a good presence at Summit. We started the week with a VC leaders meeting. I shared some information about the activities and growth during the first part of the year.   From January - September 2012: The number of VCs increased from 14 to 20 VC membership  grew from 55,200 to 80,100 Total attendance at VC meetings increased from 1,480 to 2,198 Been part of PASS Global Growth with language-based VC- including Chinese, Spanish and Portuguese. We also heard from some VC leaders and volunteers. Ryan Adams (Performance VC) shared his tips for successful marketing of VC events. Amy Lewis (Business Intelligence VC) described how the BI chapter has expanded to support PASS' global growth by finding volunteers to organize events at times that are convenient for people in Europe and Australia. Felipe Ferreira (Portuguese language VC) described the experience of building a user group first in Brazil, then expanding to work with Portuguese-speaking data professionals around the world. Virtual Chapter leaders and volunteers were in evidence throughout Summit, beginning with the Welcome Reception. For the past several years VCs have had an organized presence at this event, signing up new members and advertising their meetings. Many VC leaders also spent time at the Community Zone. This new addition to the Summit proved to be a vibrant spot were new members and volunteers could network with others and find out how to start a chapter or host a SQL Saturday. Women In Technology 2012 was the 10th WIT Luncheon to be held at Summit. I was honored to be asked to be on the panel to discuss the topic "Where Have We Been and Where are We Going?" The PASS community has come a long way in our understanding of issues facing women in tech and our support of women in the organization. It was great to hear from panelists Stefanie Higgins and Kevin Kline who were there at the beginning as well as Kendra Little and Jen Stirrup who are part of the progress being made by women in our community today. Bylaw Changes The Board spent a good deal of time in 2012 discussing how to move our global growth initiatives forward. An important component of this is a proposed change to how the Board is elected with some seats representing geographic regions. At the end of December we voted on these proposed bylaw changes which have been published for review. The member review and feedback is open until February 8. I encourage all members to review these changes and send any feedback to [email protected]  In addition to reading the bylaws, I recommend reading Bill Graziano's blog post on the subject. Business Analytics Conference At Summit we announced a new event: the PASS Business Analytics Conference. The inaugural event will be April 10-12, 2013 in Chicago. The world of data is changing rapidly. More and more businesses want to extract value and insight from their data. Data professionals who provide these insights or enable others to do so are in demand. The BA Conference offers expert content on predictive analytics, data exploration and visualization, content delivery strategies and more. By holding this new event PASS is participating in important discussions happening in our industry, offering our members more educational value and reaching out to data professionals who are not currently part of our organization. New Year, New Portfolio In addition to my work with the Virtual Chapters I am also now responsible for the 24 Hours of PASS portfolio. Since the first 24HOP of 2013 is scheduled for January 30 we started the transition of the portfolio work from Rob Farley to me right after Summit. Work immediately started to secure speakers for the January event. We have also been evaluating webinar platforms that can be used for 24HOP as well as the Virtual Chapters. Next Up 24 Hours of PASS: Business Analytics Edition will be held on January 30. I'll be there and will moderate one or two sessions. The 24HOP topics are a sneak peek into the type of content that will be offered at the Business Analytics Conference. I hope to see some of you there. The Virtual Chapters have hit the ground running in 2013; many of them have events scheduled. The Application Development VC is getting restarted  and a new Business Analytics VC will be starting soon. Check out the lineup and join the VCs that interest you. And watch the Events page and Connector for announcements of upcoming meetings. At the end of January I will be attending a Board meeting in Seattle, and February 23 I will be at SQL Saturday #177 in Silicon Valley.
