• Welcome to the Java Training Beat!

  - by tmcginn

  We are a group of dedicated training developers for Java, located in the US, India, and now Mexico. In this blog we will announce new training content and events that might be of interest to our readers. In this first installment of the Java Training Beat, I would like to introduce three new Oracle By Example (OBE) modules I recently released and posted to the Oracle Online Learning Library. Creating a Simple Java Message Service (JMS) Producer with NetBeans and GlassFish - covers how to create a simple text message producer with NetBeans 7 and GlassFish. Creating Java Message Service (JMS) Resources in WebLogic Server 12c - covers how to create JMS resources using the console and WebLogic Server 12c. With this tutorial, you can replicate the results of the first tutorial in WebLogic. Creating a Publish/Subscribe Model with Message-Driven Beans and GlassFish Server - covers how to create a publish/subscribe application using JMS. This tutorial includes a short case study that includes a JSF front-end application that sends a hotel reservation request object to the server as a MapMessage. Hope you find these useful!  And do check out the Online Learning Library - we have a wide range of additional content posted and more being added every month!

• Forward Request to Multiple Servers

  - by cactuarz

  We have 2 servers. One is old server and another is the new one. Currently we about doing a migration because the old server is not capable enough to handle everyday requests. The specs are: Old server Ubuntu 10.04 Nginx as Reverse Proxy Apache WSGI Python/Django New Server Ubuntu 10.04 Nginx Gunicorn Python/Django Celery+Redis Our manager asked us to research if the old server can perform multiple forwarding to all incoming request, for example, set Nginx of old server to forward all request to both old and new server. The purpose is to perform unit testing to new server using old server as comparer, see if the new server is ready to take over the role. Please help, if there is an idea, or must install some engine, or what we do is impossible. Many thanks.

• Chef command to create new ec2 instance with second ebs volume attached and mounted instead of the default ephemeral volume?

  - by runamok

  We currently use this command to create a new ec2 instance with chef: knife ec2 server create --node-name=prod-apache-1 --availability-zone us-east-1c --image ami-3d4ff254 --distro ubuntu12.04-gems --groups "default" --ssh-key foo --identity-file ~/.ssh/id_rsa --ssh-user ubuntu --flavor m1.small After this command we then run further chef commands to finish provisioning the server. I was wondering if it would be possible while first setting up the instance I wanted a 100 gb volume created and mounted at /mnt and to have the ephemeral storage mounted at /tmp or /mnt-ephemeral instead. If not what further commands in chef would you advise running? I know how to do this via the aws console and can probably figure out how to do it via the ec2 command line tools but I am knew to chef and a bit overwhelmed.

• How fast can a Windows 2008 CIFS client write to SAMBA server using 10Gb NIC?

  - by one_bsd_guy

  We are experiencing a performance problem using Windows 2008 CIFS client. We have a FreeNAS server that delivers 1.3GB/s on ZFS write. We have 10Gb network connecting NAS server and CIFS clients. Using two Linux CIFS clients, we can get around 1.2GB/s. But windows 2008 clients can only give us 400MB/s. Is that the best a Windows 2008 client can deliver or we do have a poorly configured Windows client? Much appreciated.

• Choosing a JavaScript Asynch-Loader

  - by Prisoner ZERO

  I’ve been looking at various asynchronous resource-loaders and I’m not sure which one to use yet. Where I work we have disparate group-efforts whose class-modules may use different versions of jQuery (etc). As such, nested dependencies may differ, as well. I have no control over this, so this means I need to dynamically load resources which may use alternate versions of the same library. As such, here are my requirements: Load JavaScript and CSS resource files asynchronously. Manage dependency-order and nested-dependencies across versions. Detect if a resource is already loaded. Must allow for cross-domain loading (CDN's) (optional) Allow us to unload a resource. I’ve been looking at: Curl RequireJS JavaScriptMVC LABjs I might be able to fake these requirements myself by loading versions into properly-namespaced variables & using an array to track what is already loaded...but (hopefully) someone has already invented this. So my questions are: Which ones do you use? And why? Are there others that my satisfy my requirements fully? Which do you find most eloquent and easiest to work with? And why?

• OpenXML error “file is corrupt and cannot be opened.”

  - by nmgomes

  From time to time I ear some people saying their new web application supports data export to Excel format. So far so good … but they don’t tell the all story … in fact almost all the times what is happening is they are exporting data to a Comma-Separated file or simply exporting GridView rendered HTML to an xls file. Ok … it works but it’s not something I would be proud of. So … yesterday I decided to take a look at the Office Open XML File Formats Specification (Microsoft Office 2007+ format) based on well-known technologies: ZIP and XML. I start by installing Open XML SDK 2.0 for Microsoft Office and playing with some samples. Then I decided to try it on a more complex web application and the “file is corrupt and cannot be opened.” message start happening. Google show us that many people suffer from the same and it seems there are many reasons that can trigger this message. Some are related to the process itself, others with encodings or even styling. Well, none solved my problem and I had to dig … well not that much, I simply change the output file extension to zip and extract the zip content. Then I did the same to the output file from my first sample, compare both zip contents with SourceGear DiffMerge and found that my problem was Culture related. Yes, my complex application sets the Thread.CurrentThread.CurrentCulture  to a non-English culture. For sample purposes I was simply using the ToString method to convert numbers and dates to a string representation but forgot that XML is culture invariant and thus using a decimal separator other than “.” will result in a deserialization problem. I solve the “file is corrupt and cannot be opened.” by using Convert.ToString(object, CultureInfo.InvariantCulture) method instead of the ToString method. Hope this can help someone.

• Backup solution

  - by user66115

  We are currently looking for a new backup solution. Our current network is 5 remote location with a tape backup in each plant. Right now we are looking at a MPLS VPN and running backups out of our main plant. The main thing that we backup are user private folders and department files. And each plant has it's own file server that houses CAD drawings. My main plan is to have every thing but that CAD drawing at the main faculty. We would start with a main backup of the drawing files and then do change backups back to the main plant. Besides tapes what would be the best way to backup. Our contact at Pc Connection is point us toward a Tandberg Data device.

• Marking Discussions as Answered

  As a contributor to a number of projects on CodePlex I really like the fact that the discussions feature exists but also I need ways to help me sort the discussions threads so I can make sure no-one is getting forgotten about. Seems like a lot of you agreed as the feature request Provide feature to allow Coordinators to mark Discussions threads as 'Answered' is our number 2 voted feature right now with 178 votes.  Today we rolled out the first iteration of “answer” support to discussions. In this first iteration we wanted to keep it simple and lightweight. The original poster of the thread along with project owners, developers or editors can mark any post to the thread as an answer. You can have any number of answers marked in a thread and it’s very quick to mark or unmark a post as an answer.  We deliberately keep the answers in the originally posted order so that you can see them in context with the discussion thread. When viewing discussions the default view is still to see everything, but you can easily filter by “Unanswered”.  You can even save that as a bookmark so as someone interested in the project can quickly jump to the unanswered discussion threads to go help out on. As I mention, we kept this first pass of the answering feature as simple and as lightweight as possible so that we can get some feedback on it. Head on over to the issue tracking this feature if you have any thoughts once you have used it for a bit or feel free to respond in the comments. I already have a couple of things I think we want to do such as a refresh of the look and feel of discussions in general along, make it easier to navigate to posts that are marked an answered and surface posts that you do that were marked as answered in your profile page - but if you have ideas then please let us know.

I am thinking that the card is DOA but could it also be the Mobo? Since I am in the BIOS I can't think how the mobo could be the problem. HD 4870 works perfect btw regardless of what I throw at it. Any way to prove that the card is OK? Thanks

• IIS wont run a BAT File

  The problem we have run into is as follows. We have an ASP.NET WebService which runs under IIS7. The code in the WebService works 100%, however when the WebService tries to run a .BAT file, nothing happens. Nothing at all, the code doesn't crash, the server doesn't warn us about anything, nothing at all. We have tried setting the User Permissions, we have attempted difference ways of running the BAT, we have tried playing around with the registry, cmd.exe has full rights as well. We are now quite stumped as of what to do, any help would be appreciated.

• What gaming keyboard(s) will work with Ubuntu?

  - by belacqua

  I've been looking at gaming keyboards to use on Ubuntu system. Microsoft has a few popular ones (e.g., Sidewinder X4, X6), but the programmable function keys appear to be unusable without the Windows software. (Though here's a post from someone who has a more recent project that uses usbmon and xdotool to add functions to some keys.) Another choice in my budget is the Cyborg V.05. It seems about right for my needs, but I would be depressed having a bunch of useless, nonprogrammable keys on it. Logitech has some models (e.g., the Logitech G110), though again I expect that the extensive macro capabilities (which I don't need) would be lost under Linux. There's a project called g15tools which has some code to work with older Logitech gaming models, but I don't know what the current status is. Last entry there was in March 2010. There are also a number of very old posts around the internet with regard to the Logitech G11 and G15. Compatibility with the current keyboards, Ubuntu version, and Linux kernel are suspect. I'm in the U.S., and so it appears that few of the Roccat keyboards are available, and they're over-priced. Support might be OK for these, though -- there's a short Phoronix article about Roccat improving their Linux support, and there's also a project and webpage for "Using Roccat Hardware with Linux". Honestly, the only feature I have to have is good backlighting for the keys, and if it's not wired (which is fine), the wireless capability should function. I could probably live with dead function keys, as long as they weren't in places that would interfere with things like Unity/compiz shortcuts. Any experience or suggestions? I've not seen much to inspire confidence with programmable/macro keys. There is a thread (with no solutions) on the Sidewinder X4 on ubuntuforums here. I'm also considering the Logitech Illuminated Keyboard as a possibility, even though it's not specifically a gaming keyboard. It is backlit, and it's supposed to be a nice keyboard.

• Scientific calculator app/site that saves calculations for Win 7?

  - by verve

  Are there any scientific calculator apps that aren't browser specific that's easy to use which displays whatever is inputted clearly and one that can be used by a keyboard only but can be used by only a mouse too? Also, I want one that saves the history of calculations and lets us paste it into a document at another time. Also, please don't recommend ones from sketchy-looking sites. Freeware or paidware. I prefer paidware if it's the only way to guarantee accurate calculations. Win 7 Pro.

• Is The Ease Of Windows Phone Development Ruining Its Image

  - by Tim Murphy

  I was reading an article on Mashable recently by a long time iPhone user who is living solely on a Lumia 920 at the moment and giving her assessment.  One thing that struck a nerve with me was her describing the Windows Phone ecosystem as immature.  She wasn’t saying this because of the number of apps or the big names like most people do.  She means the quality of the apps in the store. This hit a nerve with me.  I find it hard to believe that the majority of app on iOS are of any higher quality than any other platform.  I believe in any ecosystem you are going to find some high end, high quality apps, but the majority by default will be from people who are trying to solve a problem but do not have the resources to have top graphics and full blown testing.  There will also be a large number that are just there trying to trick you into giving up some cash. Does any of the mean that we shouldn’t take notice of this complaint?  Of course not!  We should always strive to publish the best quality apps possible.  Don’t do things like leaving default app icons and backgrounds.  Put a little effort into your design.  You should also spend as much time as possible ensuring against crashes and giving the user the best experience possible.  Think through your apps organization and navigation.  Go the extra step of putting it into beta and letting select people use it and give you feedback before going to full release. Remember, if we want people to appreciate the Windows Phone platform we have to make sure we give them apps that they are going to enjoy using. del.icio.us Tags: Windows Phone,iPhone,iOS,Nokia,Lumia 920,Mashable

• Network Monitoring Tool Recommendation

  - by user42801

  Hello, My company is looking for a monitoring app/tool that would allow us to capture and graph statistics on network performance. As a starting point, we would like to ping remote host(s) and gateway(s) from several of our servers, grab an average of the ping times from each of our servers to the remote host(s), and then graph it (preferably in a central location). Also, we would like to be able to graph the results for time frames as short as a week to as long as 6 months. It is reasonable to expect that we would ask more of the selected monitoring app/tool as we come up with other key network performance indicators in the future. So an app with great flexibility and features would be ideal. Upon first glance, Cacti looks like it might be a fit. Any other recommendations? Thanks in advance for any input.

• Spend Analytics on a Grand Scale

  - by jacqueline.coolidge(at)oracle.com

  The Wall St. Journal reports in Billions in Bloat Uncovered in Beltway that a recent study by Government Accountability Office (GAO) has released a massive study of several programs and agencies that cost U.S. taxpayers billions of dollars each year.  This report help save $100 to $200 Billion dollars by identifying duplicate spending and ineffective programs that can be consolidated or eliminated. Now, that is spend analytics on a massive scale! It remains to be seen how actionable that information will be.  Certainly, there have been studies before that identify wasteful spending.  But, it’s a great case of the power of business intelligence and spend analytics.   Many companies do find significant savings when they implement spend and procurement analytics. What makes for an excellent spend analysis? It should be: Objective and provide visibility across programs and/or divisions A cross functional analysis that links financial with performance metrics Prescriptive and actionable Spend and procurement analytics have been HOT during the economic downturn! I expect 2011 will see many more companies get serious about spend analytics and would love to hear from companies who are willing to share their experience.
