• Spirent Communications Improves Customer Experience with Knowledge Management

  - by Tony Berk

  Spirent Communications plc is a global leader in test and measurement inspiring innovation within development labs, communication networks and IT organizations. The world’s leading communications companies rely on Spirent to help design, develop, validate, and deliver world-class network, devices, and services. Spirent’s customers require high levels of support for a diverse and complex product portfolio, and the company is committed to delivering on this requirement. Spirent needed a solution to help its customers get the information they need quickly and at their convenience through its Web site. After evaluating several solutions, Spirent selected and deployed Oracle Knowledge for Web Self Service Enterprise Edition. Oracle Knowledge Management uses natural language processing to understand the true intent of each inquiry logged via the support portal’s search function. The Spirent Knowledge Base on the company’s Customer Support Center (CSC) finds the best possible answer using search enhancement features?such as communications industry-specific libraries and federation to search external sources. Spirent has reduced contact center call volume while better serving its customers. Each time a customer uses the knowledge base, they find answers faster than by calling, and it saves Spirent an average of US$210 per call?which is significant when multiplied across the thousands of calls received monthly. Oracle Knowledge also helps support engineers find answers more quickly, enabling the company to scale without adding additional support engineers. Oracle Knowledge is integrated with Spirent's Siebel Contact Center implementation to provide an integrated desktop for CRM and agent intelligence, avoiding the need for contact center personnel to toggle between various screens to address customer inquiries, thereby accelerating customer service.

• Convert MP3 to AAC,FLAC to AAC (.NET/C#) FREE :)

  - by PearlFactory

  So I was tasked with looking at converting 10 million tracks from mp3 320k to AAC and also Converting from mp3 320k to mp3 128k After a bit of hunting around the tool you need to use is FFMPEG Download x64 WindowsAlso for the best results get the Nero AACEncoder Download Now the command line STEP 1(From Flac)ffmpeg -i input.flac -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of output.m4aor (From mp3)ffmpeg -i input.mp3 -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of output.m4aNow the output.m4a is a intermediate state that we now put a ACC wrapper on via FFMpeg STEP 2ffmpeg -i output.m4a -vn -acodec copy final.aacDone :) There are a couple of options with the FFMPEG library as in we can look at importing the librarys and manipulation the API for the direct result FFMPEG has this support. You can get the relevant librarys from HereThey even have the source if you are that keen :-)In this case I am going to wrap the command lines into c# external process threads.( For the app that i am building to convert the 10 million tracks there is a complex multithreaded app to support this novel code )//Arrange Metadata about Call Process myProcess = new Process();ProcessStartInfo p = new ProcessStartInfo();string sArgs = string.format(" -i {0} -f wav - | neroAacEnc -ignorelength -q 0.5 -if - -of {1}",inputfile,outputfil) ; p.FileName = "ffmpeg.exe" ; p.CreateNoWindow = true; p.RedirectStandardOutput = true; //p.WindowStyle = ProcessWindowStyle.Normal p.UseShellExecute = false;//Execute p.Arguments = sArgs; myProcess.StartInfo = p; myProcess.Start(); myProcess.WaitForExit();//Write details about call  myProcess.StandardOutput.ReadToEnd();Now in this case we would execute a 2nd call using the same code but with different sArgs to put the AAC wrapper on the m4a file. Thats it. So if you need to do some conversions of any kind for you ASP.net sites/apps this is a great start and super fast.. With conversion times of around 2-3 seconds all of this can be done on the fly:-)Justin Oehlmannref : StackOverflow.com

  I meet are having difficulty in moving my camera behind an object in a 3D world. I would create two view mode. 1: for fps (first person). 2nd: external view behind the character (second person). I searched the net some example but it does not work in my project.

• How to solve SocketException: Permission denied: connect

  - by luxinxian

  I recently encountered a problem getting a headache, need help... System consists of: Two subsystems, called A, B (each running on a standalone tomcat instance), currently running on the same machine. A invoke B's service via spring httpInvoker(http). B system also invoke other system's services via http. Symptoms: 1, the system starts to run normally after 10-15 days; 2, the system will run for a period of time after an exception: org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service at [http://xxx.xxx.xxx.xxx/remoting/call]; nested exception is java. net.SocketException: Permission denied: connect 3, when the exception occour, it continues, not only occasional .(it looks like some resources exhausted, but cpu rate < 5%, memory < 15%, network < 5%) 4, A, B when the system call fails, B system via http call to an external service also failed for the same exception. 5, closed two tomcat services, restart, and working properly. So repeatedly (step 1 - 5), has not found the root reason. Emvironment: windows 2008 R2 tomcat7.0.42 x86_64 oralce-jdk-1.7.0_40 Any ideas?

• How to partition Seagate FreeAgent GoFlex 2TB hard disk?

  - by balki

  Hi I bought a new Seagate 2TB external hard disk. I opened the drive's application in my virtual windows, did product registration using the application present in it. I have few questions on how best to use it. The drive by default has some files and folders - setup.exe, System Volume Information, USB 3.0 PC Card Adapter etc,. I copied all the files to my laptop. Is it safe to delete these files? It has a dash board for windows which allows to tune power options, test the drive etc. Will I be able to use the dash board if I put back all these files and mount on windows again? I want to partition and format the hard disk. Data I like to store is Around 10 to 20 GB Files - Virtual box images. Around 4GB Files - Dvd images. Other Movies and personal Files. What is the best filesystem to store very huge files like 10 to 20GB files. So that they are written and accessed fast also best uses the drive's capacity. If I leave one of the partition as ntfs and others to different files systems, will it be able to mount on windows and Will I be able to use the device's dash board? Note: I dont need any encryption for my data. Any other advice on using the hard disk is also welcome.

• installing ubuntu on SSD

  - by kunal

  Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

• how to install 13.04 on a partitioned hardrive

  - by Denny

  First, not a computer literate person, not even a novice- so please use small words. I recently made the switch to ubuntu, it came preloaded on my new laptop that I order from a big tech dot com site. The version on it is 12.04 (i think) and 64bit. This system has a lot that I like but it is quirky for me to say the least. Apparently I have held broken packages and have no way of knowing how to find them. I discovered this when trying to download (from software center) VLC so that I could watch some movies I had on an external hard-drive. Unmet dependencies error and held broken package errors abound while trying to fix the problem. Ive scoured this site and other and followed almost all the suggestions to a T but still I am unable to fix anything. My computer is partitioned (but I don't even know how to get to the otherside so to speak). I would like to know; can I put the newer 13.04 OS on one side of the partition and then delete the older version on the other side? or, can I install 13.04 over the existing 12.04? What would I need to do this? An obstacle that I have is this, I am currently serving in Afghanistan so going someplace to buy something or running down to a computer store for service support is out of the question. I very much appreciate your help, cause right now this computer is nothing more than a word processor, which would be fine if all i wanted was a word processor. Thanks in advance.

• How can I convince my boss to invest into the developer environment?

  - by user95291

  Our boss said that developers should have fewer mistakes so the company would have money for displays, servers etc. An always mentioned example is a late firing of an underperforming colleague whose salary would have covered some of these expenses. On the other hand it happened a few times that it took a few days to free up some disk space on our servers since we can't get any more disk. The cost of mandays was definitely higher than the cost of a new HDD. Another example is that we use 14-15" notebooks for development and most of the developers get external displays after they spent one year at the company. The price of a 22-24" display is just a small fraction of a developers annual salary. Devs say that they like the company because of other reasons (high quality code, interesting projects etc.) but this kind of issues not just simply time-consuming but also demotivate them. In the point of view of the developers it seems that the boss always can find an issue in the past which they could have been done better so it's pointless to work better to get for a second display/HDD/whatever. How can I convince my boss to invest more into development environment? Is it possible to break this endless loop?

• Testcase runner for parametrized testcases

  - by Razer

  Let me explain my situation. I'm planning a kind of test case runner for doing testcases on external devices, which are microcontroller based. Lets consider the devices: Device 1 Device 2 There exist a lot of test cases which can be run with one of the devices above. For example: Testcase 1 Testcase 2 The main reason that all the testcases can be run with any device is, that the testcases validates some standard and this software should be extensible for future devices. The testcases itself must be runnable with changing parameters. For example Testcase 1 does some Timing Verification the testcase needs as input parameter the datarate: 4800, 9600, 19200. Now hoping you understand the situation, let me explain my design questions. For implementing the test cases I thought about an Attribute based approach, like nunit does it. The more complicated problem is, how to define the parametrized testcases? Like this: Device 1: Testcase 1: datarate: 4800, 9600, 19200 Testcase 2: supply: 1, 2, 3 Device 2: Testcase 1: datarate: 9600, 19200, 38400 Testcase 2: supply: 3, 4, 5 How would you design such a framework? I've done a similar desin in python where I had for every device a XML containing the testcase definitions like: <Testcase="Testcase 1" datarate=4800/> <Testcase="Testcase 1" datarate=9600/> <Testcase="Testcase 1" datarate=19200/>

• How does a one-man developer do its games' sounds?

  - by Gustavo Maciel

  Before anything, that's not a "oh, where can I find resources?" question. Well, I've been curious about one thing in the indie games industry. For the development of the game, such tasks like game design, art, sketches, code programming and etc can be easily done by just one person. You can just take up a paper and pencil and you're a game designer. You can just take software like Photoshop or Paint and you're an artist, a scanner and you're a sketcher, a compiler and you're a programmer. For sound it's different. You may tell me: Well, follow the line, take a lot of instruments and record it. But all we know that things don't work this way. I can list up some changes for us: External noises are a big problem, sound effects can't be made with instruments, it can't sound like a recorded and clipped sound. Well I can imagine how they do this in large companies, with such big studios and etc. But to summarise, my question is: What's the best way for a one-man indie to do all its sound? Does he have to synthesize everything? Record and buy some crazy program for editing sounds?

• Kubuntu 12.04 - DNS Issues

  - by AndrewJesaitis

  Starting yesterday (6/11/12), I've been having many network problems. When requesting a page in chrome, the page hangs on "Sending request" and then will eventually timeout. I'm within a VPN that has it's own DNS server. I've tried to manually set my DNS through the Network-Manager applet and by editing /etc/network/interfaces. Having no luck I unlinked the resolv.conf file and dumped the contents of my old resolv.conf into it. Again having no luck, I deactivated the dnsmasq server in /etc/NetworkManager/NetworkManager.conf by commenting out the dns=dnsmasq. $ cat NetworkManager.conf [main] plugins=ifupdown,keyfile #dns=dnsmasq no-auto-default=D0:67:E5:EA:B6:6B, [ifupdown] managed=false $ nm-tool NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: D0:67:E5:EA:B6:6B Capabilities: Carrier Detect: yes Speed: 1000 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.254.122 Prefix: 24 (255.255.255.0) Gateway: 192.168.254.2 DNS: 192.168.254.1 What is strange is that the network will work fine for a few minutes then start to timeout. A few minutes later it will work again. I'm unable to hit internal or external sites when it is timing out. When I $dig local sites, I receive no answer. I do receive an answer from google.com. At this point, I would usually blame the DNS Server, especially since when I change to Google's DNS server things work. But, I need to use our internal DNS to hit our internal sites. Nobody else is having issues and they are all using DHCP. This group includes one user who is using 11.04. At this point, I'm at a loss for what to do, so any help would be appreciated.

• Why does everybody hate SharePoint?

  - by Ryan Michela

  Reading this topic about the most over hyped technologies I noticed that SharePoint is almost universally reviled. My experience with SharePoint (especially the most recent versions) is that it accomplishes it's core competencies smartly. Namely: Centralized document repository - get all those office documents out of email (with versioning) User-editible content creation for internal information disemination - look, an HR site with current phone numbers and the vacation policy Project collaboration - a couple clicks creates a site with a project's documents, task list, simple schedule, threaded discussion, and possibly a list of all project related emails. Very basic business automation - when you fill out the vacation form, an email is sent to HR. My experience is that SharePoint only gets really ugly when an organization tries to push it in a direction it isn't designed for. SharePoint is not a CRM, ERP, bug database or external website. SharePoint is flexible enough to serve in a pinch, but it is no replacement for a dedicated tool. (Microsoft is just as guilty of pushing SharePoint into domains it doesn't belong.) If you use SharePoint for what it's designed for, it really does work. Thoughts?

• Unknown CSS font-family oddity with IE7-10 on Windows Vista, 7, 8

  - by Jeff

  I am seeing the following "oddity" with IE7-10 on Windows Vista, 7, 8: When declaring font-family: serif; I am seeing an old bitmapped serif font that I can't identify (see screenshot below) instead of the expected font Times New Roman. I know it's an old bitmapped font because it displays aliased, without any font smoothing, with IE7-10 on Win Vista-8 (just like Courier on every version of Win). Screenshot: I would like to know (1) can anyone else confirm my research and (2) BONUS: which font is IE displaying? Notes: IE6 and IE7 on Win XP displays Times New Roman, as they should. It doesn't matter if font-family: serif; is declared in an external stylesheet or inline on the element. Quoting the CSS attribute makes no difference. Adding "Unkown Font" to the stack also makes no difference. New Screenshot: The answer from Jukka below is correct. Here is a new screenshot with Batang (not BatangChe) to illustrate. Hope this helps someone.

• Materialized View vs POJO View based on Objects representing Oracle tables

  - by Zack Macomber

  I have about 12 Oracle tables that represent data that's being integrated from an external system into my web application. This data is going to be used in an informational and comparative manner for the clients using my web application. On one particular page of my web application, I need to combine data from 3 - 5 Oracle tables for display as an HTML table on the page. We are NOT currently using a framework (Apache Struts for instance) and we're not in a position to move this Java web application into one at this moment (I'm trying to get us there...). I am certainly not an architect, but I see one of two ways that I can effectively build this page (I know there are other ways, but these seem like they would be good ones...): 1. Create an Oracle Materialized View that represents what the HTML table should look like and then create a POJO based on the View that I can then integrate into my JSP. 2. Create POJOs that represent the Oracle tables themselves and then create another POJO that is the View used for the HTML table and then integrate that POJO into my JSP. To me, it seems the Materialized View would possibly offer quicker results which is always what we strive for in web applications. But, if I just create 12 POJOs that represent the Oracle tables and then build POJO Views off of those, I have the advantage of keeping all the code in one place for this and possibility for creating any number of different views and reusable components in my web application. Any thoughts on which one might be the better route? Or, maybe you know of an even better one?

• Unity Greeter login screen cuts off login options

  - by ammianus

  I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

• Can't access any functions after chown command.

  - by explorex

  I am not being to access any functions in my desktop and I don't have an OS besides Ubuntu and I am new to Ubuntu. I think I rebooted my computer thinking that Google Chrome crashed. I opened Google Chrome but it showed opening message but never opened so I restarted my computer. and when my system was loading (I was playing with keyboard dont know what I typed) and when by Ubuntu loaded, I was unable to access anything some of characteristics are listed below: I cannot hear any sound I cannot access wired ethernet connection on the right corner where I usually enable to access internet and I have no internet. There is no local apache server either. when ever I try to start apacer I get setuid must be root or something. When I type sudo then I get message setuid must be root. I cannot access orther external storage devices like pendrive and portable hard drive and cannot mount my other drives with FAT32 filesystem. When I try to start my apache webserver with out typing sudo then I get message cannnot open socket or something like it. I remember also doing command chown -R www-data / earlier and got error message I cannot shutdown my computer, it only logs off

• Show USB drives in launcher, but not mounted internal partitions

  - by Gabriel

  Well the title pretty much says it all. I have partitions that appear in the launcher when the system mounts them, just like when a USB key is plugged in. I do not want these mounted internal hard disc partitions to show as icons in the launcher, but I do want my external USB to show there when I plug it in. I've tried MyUnity - it has only an option to not show/hide all mounted devices, which is not what I want. Can this be done? From /proc/mounts (in order seen in screenshot): /dev/sdb1 /media/CEDD-DE31 vfat rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=cp437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0 /dev/sda3 /media/A423-E0E8 vfat rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=cp437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0 /dev/sda5 /media/586C25656C253EDE fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0 /dev/sda6 /home/greg/80gb ext4 rw,relatime,user_xattr,barrier=1,data=ordered 0 0 Other items from /proc/mounts not appearing in Unity launcher: /dev/sda1 /boot/efi vfat rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0 /dev/sda9 /mnt/backup ext4 rw,relatime,user_xattr,barrier=1,data=ordered 0 0

  - by user35201

  Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount.

• Installer gets stuck with a grayed out forward button.

  - by TRiG

  I have a CD with Ubuntu 10.10 and a laptop with Ubuntu 8.10. The laptop had all sorts of crud on it, and anything I wanted to keep was backed up on an external drive, so I was happy to do a wipe and reinstall instead of an update. So after a bit of faffing about trying to work out how to get the thing to boot from the CD drive, I did that. So the screen comes up with the choice: the options are Try Ubuntu and Install Ubuntu. I choose to install and to overwrite my current installation. So far so good. I then get a progress bar labelled something like copying files (I forget the exact wording) and further options to fill in for my location, keyboard locale, username and password. On each of these screens there are forward and back buttons. On the last screen (password), the forward button is greyed out. Well, I think to myself, no doubt it will become active when that copying files progress bar completes. The progress bar never completes. It hangs. And the label changes from copying files to the chirpy ready when you are. The forward button remains greyed out. The back button is as unhelpful as you'd expect it to be. And there's nothing else to click. We have reached an impasse. I tried restarting the laptop, to test whether it actually was properly installed. It wasn't. I tried to run Ubuntu live from the CD, to test whether the disk was damaged. That wouldn't work either, but I suspect it's just because the laptop is old and has a slow disk drive. I'm typing this question on another computer using the Ubuntu live CD and it's working fine. So there's nothing wrong with the CD.
