• I Can't run the Netbeans but I installed successfully

  - by David

  I'm new to Ubuntu as well as Netbeans. I installed Netbeans, and I've made sure to install all the JDKs and JREs I could find. It installed without errors. I also saw this question and made sure I followed all the instructions there as well. I never got any error messages of any kind. So far as I know, it installed okay. However, when I try to run Netbeans, I get the message in the bottom of the Netbeans IDE like this: ant -f /root/NetBeansProjects/samp1 -Djsp.includes=/root/NetBeansProjects/samp1/build/web/one.jsp -DforceRedeploy=false -Dclient.urlPart=/one.jsp -Ddirectory.deployment.supported=true -Djavac.jsp.includes=org/apache/jsp/one_jsp.java -Dnb.wait.for.caches=true run /root/NetBeansProjects/samp1/nbproject/build-impl.xml:774: The libs.CopyLibs.classpath property is not set up. This property must point to org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part of NetBeans IDE installation and is usually located at <netbeans_installation>/java<version>/ant/extra folder. Either open the project in the IDE and make sure CopyLibs library exists or setup the property manually. For example like this: ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar BUILD FAILED (total time: 0 seconds)

• Why is a software development life-cycle so inefficient?

  - by user87166

  Currently the software development lifecycle followed in the IT company I work at is: The "Business" works with a solution manager to build a Business Requirement document The solution manager works with the Program manager to build a Functional Spec The PM works with the engineering lead to develop a release plan and with the engineering team to develop technical specifications If there are any clarifications required, developers contact the PM who contacts the solution manager who contacts the business and all the way back introducing a latency of nearly 24 hours and massive email chains for any clarifications By the time the tech spec is made, nearly 1 month has passed in back and forth Now, 2 weeks go to development while the test writes test cases Code is dropped formally to test, test starts raising bugs. Even if there is 1 root cause for 10 different issues, and its an easily fixed one, developers are not allowed to give fresh code to test for the next 1 week. After 2-3 such drops to test the code is given to the ops team as a "golden drop" ( 2 months passed from the beginning) Ops team will now deploy the code in a staging environment. If it runs stable for a week, it will be promoted to UAT and after 2 weeks of that it will be promoted to prod. If there are any bugs found here, well, applying for a visa requires less paperwork This entire process is followed even if a single SSRS report is to be released. How do other companies process such requirements? I'm wondering why, the business cannot just drop the requirements to developers, developers build and deploy to UAT themselves, expose it to the business who raise functional bugs and after fixing those promote to prod. (even for more complex stuff)

• Kind of lost, and I don't know where to start

  - by Rasheed Mehrinfar

  I am 16-year-old who's always been interested in the world of programming. I was wondering if anyone could point me in the right direction in what language I should learn first, and possibly suggest any good tutorials/ guides to learn from. Also, do you think it's worth it to kinda of "play around" and get familiar with a program like 3ds max, as my goal is to work in the gaming industry. Or would that just be a waste of time?

• Need some critique on .NET/WCF SOA architecture plan

  - by user998101

  I am working on a refactoring of some services and would appreciate some critique on my general approach. I am working with three back-end data systems and need to expose an authenticated front-end API over http binding, JSON, and REST for internal apps as well as 3rd party integration. I've got a rough idea below that's a hybrid of what I have and where I intend to wind up. I intend to build guidance extensions to support this architecture so that devs can build this out quickly. Here's the current idea for our structure: Front-end WCF routing service (spread across multiple IIS servers via hardware load balancer) Load balancing of services behind routing is handled within routing service, probably round-robin One of the services will be a token Multiple bindings per-service exposed to address JSON, REST, and whatever else comes up later All in/out is handled via POCO DTOs Use unity to scan for what services are available and expose them The front-end services behind the routing service do nothing more than expose the API and do conversion of DTO<-Entity Unity inject service implementation to allow mocking automapper for DTO/Entity conversion Invoke WF services where response required immediately Queue to ESB for async WF -- ESB will invoke WF later Business logic WF layer Expose same api as front-end services Implement business logic Wrap transaction context where needed Call out to composite/atomic services Composite/Atomic Services Exposed as WCF One service per back-end system Standard atomic CRUD operations plus composite operations Supports transaction context The questions I have are: Are the separation of concerns outlined above beneficial? Current thought is each layer below is its own project, except the backend stuff, where each system gets one project. The project has a servicehost and all the services are under a services folder. Interfaces live in a separate project at each layer. DTO and Entities are in two separate projects under a shared folder. I am currently planning to build dedicated services for shared functionality such as logging and overload things like tracelistener to call those services. Is this a valid approach? Any other suggestions/comments?

• Hardware recommendations for building an Ubuntu encrypted file server

  - by Robert Mashlan

  I would like to build a file server for my home network using Ubuntu. It will serve files from RAID1 configured disks, either in the OS or in hardware. It will be connected to a Gigabit ethernet LAN. The disks will use an encrypted file system. It will serve samba shares. I would like a recommendation on what kind of processing power/memory I would need to build a box that would be able to sustain the full capacity of the Gigabit ethernet connection in a file transfer for a single connection with the overhead of serving from an encrypted disk. I'm not looking to build a dream server, I just want enough processing capacity for high performance (and reliable) file sharing and spend as little as possible for it. This may be tangential, but what kind of hardware would I need to have a server be able to reliably go into a low power mode when no requests are being made of it?

• HDDs randomly falling off raid

  - by michael

  I really need help on this it's Saturday long weekend.No customer service help:( .I recently build new server/light duty desktop.Main purpose is only file sharing.Raid configuration :Adaptec 6805 ,8x 3TB HDD WD Red,Intel RES2SV240 expander,Raid 6,set in Intel mobo DZ 77GA-70K.I upgraded firmwares, but I'm having strange problem. During Build Verify segment 7 got missing.I just reinsert drive into hot swap bay and it started to rebuild Array.After rebuild was done another segments 0 and 5 gone missing while build/verify.I reinserted drives and now I'm praying that raid is going to rebuild successfully from remaining 6 drives,because i already transfer some data on it(I know it was bad idea).I checked S.M.A.R.T on missing drives , it only says link failure and aborted commands on one of them.No Errors on HDDs.Connections and cables are good.I added 2 fans blowing on RAID controller because it was getting too hot, so I guess overheating shouldn't be issue.What can be possibly wrong? Thank you for help.

• Excellent C Tutorials

  - by nebffa

  I've looked high and low for C tutorials that have lots of exercises to do along the way, but in my experience all the guides I've found have mostly explanation with a bit of code pre-written, lacking exercises for you to do. I started learning Python using Learn Python the Hard Way, and for almost all other standard languages there are good sites to learn and grapple with the syntax - for example codecademy.com, programr.com. Is there any site like any of the above for C?

  I'm sort of a beginner with eclipse but I want to update the libraries or build path or whatever to java 1.7 from java 1.6 and I can't figure it out.

• MXMLC Ant task results in java.lang.OutOFMemoryError

  - by Mims H. Wright

  I'm making a change to a set of code for a Flex project that I didn't write and was set up to compile using ant tasks. I assume that the codebase was stable at the last checkin but I'm running into memory issues when trying to build a project using MXMLC and ant (see stack trace below). Before, I was just getting an out of memory error. I tried using a different machine and got this more verbose exception (including problems with the image fetcher). I've tried using various versions of the SDK, I've tried replacing the <mxmlc> tag with <exec executable="mxmlc"> with no luck. Here is my java version in case that has anything to do with it: » java -version java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065) Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode) Any help would be appreciated.
