  • How to build a NAS?

    - by Walter White
    Hi all, I have quite a bit of photos I'd like to organize and get away from sparse DVDs and move to a NAS solution. Ideally, this would let me have some level of redundancy and more easily find what I'm looking for. That being said, hard drives are relatively cheap. My next question is, I would like to run ZFS on the drives with the ability to add / remove drives for additional redundancy, or change the configuration of the drives possibly. Is there a NAS box that let's you run your OS of choice (FreeNAS) so all I'd need to do is get the hard drives, the NAS box, and modify the firmware / OS with FreeNAS? Walter

  • ODF (Open Document Format) para ISVs - 16/Dez/10

    - by Paulo Folgado
    Os ISVs (Independent Software Vendors) sentem frequentemente necessidade de incluir nas suas aplicações uma funcionalidade de exportação de informação - uma carta, uma tabela com dados financeiros, um gráfico, etc - para que possa ser trabalhada externamente com ferramentas ditas de Produtividade num 'desktop' (também designadas por 'Suites de Office'). Nessas situações são confrontados com a necessidade de elegerem que formato deve ser usado para essa exportação de dados, sendo a escolha mais usual a utilização dos formatos do Microsoft Office. Contudo, se fôr essa a sua única opção, estarão a auto excluir-se de um mercado em crescimento constituído pelos clientes que utilizam outras ferramentas de produtividade, nomeadamente as que são baseadas no standard ISO Open Document Format (ODF), como é o caso do Open Office. Este seminário tem por objectivo dar aos parceiros ISVs da Oracle: Uma visão sobre o mercado actual de 'suites' de Office e dos standards usados pelos principais fornecedores de soluções A estratégia da Oracle para o Open Office Razões para deverem suportar a norma ODF Como suportar ODF nas suas aplicações Agenda O mercado actual das Suites Office Os standards actuais "de facto" e oficiais - MS-Office, OOXML e ODF Que produtos usam o ODF hoje Estratégia Oracle para o Open Office Porquê suportar ODF nas aplicações Como adaptar as aplicações actuais à utilização de ODF Local: Oracle - Lagoas ParkData: 16 de DezembroDuração: 1/2 diaHorário: 9:30 - 12:00 Inscrições: Email, ou pelo telefone 211929708 Para mais informações, por favor contacte Claudia Costa via Email ou telefone 214235027.

  • Is this an apt-get issue or network issue?

    - by zharvey
    I just installed my first Ubuntu server (12.04) instance and immediately am noticing a few things: Running apt-get install or update fails (see below) Running ifconfig produces peculiar IP addresses starting with 10.x.x.x and my router does not see the server at all in its "Attached Devices" page (its a consumer grade Netgear) When I run apt-get I get 50+ of the following errors: Failed to fetch <some-http-url. Temporary failure resolving <blah.ubuntu.com I read up on this error for 12.04, and found some similar posts on this forum and on serverfault that recommended going into /etc/resolv.conf and adding an entry: nameserver 8.8.8.8 To my surprise, I found that /etc/resolve.conf was a symlink pointing to somewhere else and I had to delete it first, then create a new one with the entry indicated above. I restarted the server and tried running apt-get again: same results. How do I start diagnosing the problem (I'm a relatively new Linux/Ubuntu user)? Additional details that may help: This is actually a virtual machine running as a VirtualBox guest OS The physical host that is running this VM is my laptop which has a wireless connection; I'm wondering if (somehow) the laptop is getting the network wirelessly, but perhaps either the VBox VM and/or the Ubuntu server OS isn't configured for wireless and so nothing is "getting through"? Thanks in advance for any pointers! Edit: Here is a snapshot of my VM's Network settings (only Adapter 1 has any information populating its fields, so I assume my VM has only 1 adapter): Here is the output when I run ifconfig from the terminal: And here is the output when I run route from the terminal: Running ping google.com:

  • How to check system performance?

    - by Woltan
    Hi all, I am a new Ubuntu user and really like the look and the features of the OS. However, I have a feeling that the performance could be better. With that I mean: Somehow the scrolling within firefox of sites seems laggy. I do not know how I should measure it but there is a difference. Not that it is unusable but it is aggravating. Java programs are running really slow. As a comparison (I know it is not a fair one), I tried to run a game using wine. The graphic specifications using windows were much higher (1600x1200) with a high level of detail, and in ubuntu with the lowest level of detail 1024x768 was the maximum. (My graphics card is a GeForce GTS 450 with 1gb RAM) Coming to my question: Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something!? Any help, link, suggestion is appreciated! Cherio Woltan

  • Configuring Weblogic Server 10.3.6 from 32-bit mode to 64-bit mode

    - by Ekta Malik
    This post pertains to the configuration of Weblogic Server from 32-bit mode to 64-bit mode on Solaris OS. Just in case, you have WLS 10.3.6 running in 32-bit mode and the JDK being used is installed for 64-bit mode [On Solaris OS, JDK 64-bit installation comprises of installing 32-bit JDK followed by a patch for 64-bit JDK].  Verification of the mode being used One can verify the mode of Weblogic Server in the following ways Either check the commonEnv.sh script located at $MIDDLEWARE_HOME/wlserver_10.3/common/bin where $MIDDLEWARE_HOME refers to the install directory of Middleware. Look for the patterns - SUN_ARCH_DATA_MODEL and JAVA_USE_64BIT in the file. For 32-bit mode, the parameters would appear as shown belowSUN_ARCH_DATA_MODEL="32"JAVA_USE_64BIT=false Check the server console logs; which JDK is being used during start-up By checking which JDK is used by the running process of Weblogic Server Configuration Steps Take a backup of the commonEnv.sh script located at $MIDDLEWARE_HOME/wlserver_10.3/common/bin where $MIDDLEWARE_HOME refers to the install directory of Middleware Modify the commonEnv.sh script for the following parameters: The values should be 64 and true respectively for 64-bit modeSUN_ARCH_DATA_MODEL="64"JAVA_USE_64BIT=true  Restart the weblogic server. One can confirm that the JDK being used is 64-bit by looking at the Weblogic console logs during server start up or by looking at the running process.

  • winusb formatting and installation error, lost data storage on 32gb flash drive

    - by Cary Felton
    i recently purchased a pny brand 32gb usb drive to use for configuring a dual boot on my computer, and for hdd files backup. i also recently installed zorin os 6.1 as my main os, and then downloaded winusb for linux, and set it to install the iso for windows 8 release preview as the activation code is still good untill jan.2013, and there was an error on the installation. i rebooted the computer, plugged in the usb drive, and i went from 32gb usable space to somehow having a partitioned drive (mounted as two separate drives) one being 3.7gb, and the other being i believe 25gb or so... i then formatted the drive with gparted back to fat32, and it still read as a windows usb with the installation files on it still? so then i took my usb drive to my library which runs windows 8, i installed bootice, and completely reformatted my usb drive, and somehow it is usable, but still not perfect. it reads i only have 29.9gb usable space... i have already thought of the non usable area, and that doesnt account for this error as when i first bought the drive and plugged it in on linux, it read total drive space was 32.2 and exactly 32 was usable. somehow i am short by 2gb of space which is very critical for what i am doing. i love linux, i only needed windows for bluray playback with daplayer as it wont work well in wine, but if i keep losing space on my usb drives im afraid ill have to switch back. any help would be appreciated as i already visited pny's site, and they have no support for this issue, and im not that fond of partitions, file systems, or formatting.

  • Asus P6X58D & 12GB of RAM

    - by Hunter
    I just assembled my new PC and it screams, BUT it's only recognizing 8GB of ram in BIOS and OS rather than the installed 12GB. In the BIOS the RAM was registering at 1066 so I set it to 1600MHz.

  • Foward slash in kibana 3 query

    - by G Mawr
    I'm trying to add a query that will match a request that ends with a slash, like this one: n.n.n.n - - [16/Oct/2013:16:40:41 +0100] "GET / HTTP/1.1" 200 25058 "-" "Mozilla/5.0 (iPad; CPU OS 7_0_2 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A501 Safari/9537.53" I'm using the Lucene query type. If my query is set to *, I see the event. If I set it to request:"css", I see CSS requests, as expected. However, all of the following yield no results: request:"/" request:"\/" request:"\\/" I tried a Lucene regular expression, with no luck: request:/\// I note that someone else is getting what appears to be a similar issue, although that's on Kibana 2: https://github.com/rashidkpc/Kibana/issues/401 How can I query for requests that end with a / character?

  • windows server 2008 vs ubuntu 11 [closed]

    - by user472875
    I am working on implementing a custom server application that should be capable of handling a very large volume of traffic. I am aware that this type of question has been asked a lot, but I haven't been able to find a good answer. What I'm really looking for is for a server with given specs which OS will be able to handle a larger traffic faster and more reliably. I do not care about rights management or any other features. I am fairly good with both platforms, and so I would like to pick the OS with better performance on a clean install, and with nothing else running. Thanks in advance.

  • Third party biometric software.

    - by Iszi
    Most of us with fingerprint readers and such devices probably use the software provided by the vendor, to enable biometric OS login or single sign-on functionality. However, I've recently wondered if there is any third-party software that will do the same thing? This would be similar to how you don't need the manufacturer's software to use a scanner, printer, or webcam - you just use their drivers and your choice of software. Is there anything like this for fingerprint readers or other biometric devices? Free or Open Source projects are preferred, but I'd be interested in learning about any existing solutions regardless. I personally am particularly interested in Windows-compatible software, but I'll leave the query open for any OS.

  • Windows 7 Activation: Can I use OEM key for retail version? [closed]

    - by Joudicek Jouda
    Possible Duplicate: Windows 7 and Vista Activation FAQ: How do language, version, 64-bit or 32-bit, and source affect ability to install and transfer Windows licenses? I have a Lenovo notebook with pre-installed Windows 7 Professional x64. I just did a clean reinstall with retail installation Win7 Professional x64 disk I got from MSDNAA programme I'm member. I wanted to install the OS as Lenovo OEM with the same key I had before, but when I tried to activate the newly installed Windows, it gave me 0xc004e003 error. So the question is, can I use my OEM key for Win7 installed as retail? If not, can I somehow change the installed OS to OEM? The other think is, the OEM key I have tried is just some key I found in my notes, because I don't have any Windows sticker on beneath my laptop as it used to be on all my previous ones. Can I somehow find out "what is the origin" of the supposed key I'm trying to use?

  • Missing disc when installing windows 7

    - by Anders
    Hi, when I was installing windows 7 on my new bought computer it asked me on which disc I would like to install the OS on, either the 1 tera byte disc or the ssd disc, I chose to install it on the ssd disc. But now when I have installed the OS, the 1 tera byte disc isn't visible in "my computer" and I don't know how to access it, I didn't do anything strange in the installation, that by the way is idiot secure. So my question, what do you think have happend and how do you believe that this issue is solved? Regards Anders

  • Ask the Readers: Do You Use the Command Line?

    - by Jason Fitzpatrick
    Despite over two decades of GUI interfaces many power users still turn to the command prompt. This week we want to hear about when and how you use the command prompt on your computer. Long ago in a time before you could manipulate your computer with a mouse and a series of buttons and windows, the command line ruled all. Even after years of GUI development and refinement many people still turn to the command line to get things done. This week we want to hear all about your command line tips and tricks. Do you use the default command line for your OS? Have you enhanced it? Replaced it? What keeps you coming back to the command line when everyone happily works away in the OS’s GUI?

  • Create USB installer from the command line?

    - by j-g-faustus
    I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. unetbootin scripting: Requires X server (graphics support) to run, even when fully scripted. (The command sudo unetbootin lang=en method=diskimage isofile=~/ubuntu-10.10-server-amd64.iso installtype=USB targetdrive=/dev/sdg1 autoinstall=yes gives an error message unetbootin: cannot connect to X server.) Update Also tried GRUB fiddling: Merging information from pendrivelinux.com a related question on the Linux Stackexchange and a grub configuration example I was able to get halfway there - it booted from USB, displayed the grub menu and started the installation, but installation did not complete. For reference, this is the closest I got: sudo su # mount USB pen mount /dev/sd[X]1 /media/usb # install GRUB grub-install --force --no-floppy --root-directory=/media/usb /dev/sd[X] # copy ISO image to USB cp ~/ubuntu-10.10-server-amd64.iso /media/usb # mount ISO image, copy existing grub.cfg mount ~/ubuntu-10.10-server-amd64.iso /media/iso/ -o loop cp /media/iso/boot/grub/grub.cfg /media/usb/boot/grub/ I then edited /media/usb/boot/grub.cfg to add an .iso loopback, example grub entry: menuentry "Install Ubuntu Server" { set gfxpayload=keep loopback loop /ubuntu-10.10-server-amd64.iso linux (loop)/install/vmlinuz file=(loop)/preseed/ubuntu-server.seed iso-scan/filename=/ubuntu-10.10-server-amd64.iso quiet -- initrd (loop)/install/initrd.gz } When booting from USB, this would give me the Grub boot menu and start the installer, but the installer gave up after a couple of screens complaining that it couldn't find the CD-ROM drive. (Naturally, as the box I'm installing on doesn't have an optical drive.) I resolved this particular issue by giving up and doing the "create USB drive" routine using the Ubuntu Live desktop CD (on a computer that does have an optical drive), then the USB install works. But I expect that there is some way to do this from the command line of an Ubuntu system without X server and without an optical drive, so the question still stands. Does anyone know how?

  • Undertanding .bashrc and .bash_profile

    - by Blankman
    On a server when I login as root I see .bashrc (ubuntu 10.10). On my Mac I have a .bash_profile, does ubuntu always have only a .bashrc file and not .bash_profile? (just confused so asking, I realize they are different o/s's but maybe there is a relationship somehow?) On my server, I want to create an alias, should I put it in .bashrc? What if I want this alias to be applied so all users can use it?

  • Exciting product releases (and one disappointing thing) with Mix10

    - by Jeff
    Sadly, I'm not at Mix this year, for the first time in a few years. It's a little harder to go if you work for Microsoft, oddly enough. And then there's this little guy next to me, who at ten days old really needs his daddy to be around! But oh, the excitement of what Microsoft has in store! It's great to finally see all of these major releases coming together for Microsoft developer products. There is a great deal of excitement among people internally no matter where you work, because there is so much cool stuff in the pipe. In case you live under a rock...Visual Studio 2010 - Great to see all of the positive feedback on the Twitter and what not. I've been using it on one of my home products for awhile, and I really like it. The newer nightly builds of ReSharper also seem to be gaining speed in quality as well. I like the new debugging features, and the text readability is not imagined. Love it.Silverlight 4 - I've been running a couple of minor SL3 apps on my personal sites for awhile now, and I'm thrilled with the platform. With a couple of key concepts down, .NET folk like you and me can do some stellar things with this, and if you're a Mac nerd (like me), it's all kinds of awesome to be able to build stuff for it without the agony of Objective-C and X Code.Windows Phone 7 Series - A few weeks ago you got to see the shiny new UI that went beyond the icon grid, and now you've got the developer story as well. That I can adapt my existing Silverlight apps with minimal effort to work on the phone is pretty powerful. Millions of .NET devs just because phone developers, using the tools they already know. How great is that?ASP.NET MVC2 - The final bits shipped last week, and there was much rejoicing. I love this framework because of the testability and the real ability to get to the true mechanics of HTTP. The other cool thing is the speed at which the framework has evolved. v2 in less than a year is pretty "un-Microsoft" in a lot of eyes.The video of keynotes and sessions is starting to appear on the Mix site, but for reasons I can't understand, they're WMV downloads. For real? Not that helpful for Mac folk. Why wouldn't they be using a Silverlight player?In any case, the thing that continues to motivate me is that getting what you imagine on to the Internet gets easier every year. This is not a new revelation for me. I've only been at Microsoft for four months, but I've felt this way for years. I'm thrilled to be a part of it.

  • Recover from a recover partition when F11 doesn't work and windows is corrupt

    - by jherlitz
    I have someones presario V3000 laptop. It has a D drive which is the recovery partition. The user brought it to me and windows would no longer even boot up. I could only reload XP and try to find a way to recover from the recovery partition. However haven't been able to. I read, hold F11 down when booting up, but that didn't do anything, and the other item I read is to create the CDs from the software installed in the OS from the factory. Well that is the OS that went corrupt and is no longer there. A new reloaded version of XP is there now. Is there still a way I can either create recover CD's/DVD's or boot from the recovery partition?

  • Building optimal custom machine for Sql Server

    - by Chad Grant
    Getting the hardware in the mail any day. Hardware related to my question: x10 15.5k RPM SAS Segate Cheetah's x2 Adaptec 5405 PCIe Raid cards Motherboard has integrated SAS raid. Was thinking I would build 2 RAID 10 arrays one for data and one for logs The remaining 2 drives a RAID 0 for TempDB Will probably throw in a drive for OS. Does putting the Sql Server application / exe's on a raid make a difference and is there any impact of leaving the OS on a relatively slow disk compared to the raid arrays? I have 5/6 DBs combined < 50 gigs. With a relatively good / constant load. Estimating 60-7% reads vs writes. Planning on using log shipping as well if that matters. Any advice or suggestions?

  • Hybrid Graphics on Windows 7/Ubuntu 12.04 Dual Boot

    - by Noob.
    Alright, so here's the situation: I am using an ASUS UL80VT with two graphics cards: Integrated intel graphics and NVIDIA G210M I was running an Ubuntu 12.04 - Windows 7 dual boot (on separate partitions).The machine worked perfectly (including the display drivers) without me needing to install anything special or change any settings. However, my hard drive was corrupted and I lost all my data yesterday, so after it was replaced, I installed Ubuntu 12.04 64x again after installing Windows 7. I booted up Ubuntu after installation, and noticed it was by default using Unity 2D... Gnome 3.4 wasn't working properly either, so I guessed that the NVIDIA G210M driver wasn't installed/working and the OS was instead using the integrated graphics. I checked the "Additional Drivers" thing, but there were no proprietary drivers listed there, so I went to the NVIDIA website, downloaded the driver directly and installed it. I restarted, but there was no change. After this, I read somewhere that I should change my SATA in the BIOS to "Compatible" rather than "Enhanced". This worked fine and fixed the problem (both Unity and Gnome were working perfectly) but then when I tried booting up Windows 7, I recieved the BSOD. So I changed it back to Enhanced, and once again, the NVIDIA 210M graphics isn't working on Ubuntu, but on Windows 7 it is. I do not want to keep changing from Enhanced to Compatible every time I reboot to Ubuntu and neither do I want to simply just use one OS. Note that NVIDIA 210M and integrated graphics work perfectly on Windows 7. Also, I don't care about switching between them, I just want to be able to use the NVIDIA one. What can I do so that both Windows 7 and Ubuntu work and NVIDIA G210M works on Ubuntu?

  • Prevent Win7 boot loader from taking over the WinXP boot loader

    - by Chris
    My setup: 1 physical hard drive (500gb divided equally into 2 partitions) Windows XP Partition (Current OS) Empty Partition where I will be installing Windows 7 My question is how do I prevent the Windows7 boot loader from taking over my WindowsXP boot loader when installing the new OS ? The reason I am asking is because I already have a ghosted backup of my WinXP partition and if I ever need to restore my xp partition using that backup, would it not overwrite the Windows7 boot loader that was placed in the XP partition with the one from the backup, thus making windows 7 unable to boot. Also what would happen if I decided to delete the Windows XP partition altogether somewhere down the road and along with it the Win7 boot loader that was placed there, wouldn't that cause the system not to boot at all.. To avoid these issues, I simply want to make sure that BOTH the Win7 and WinXP boot loaders are available on their respective partitions and they do not interfere with each other in any way. Is this possible? Thx, Chris

  • Windows 7 Via Hyperion 4-1 drivers

    - by Gratzy
    I have a clean install of Win 7 on some relatively old hardware. Everything works pretty well however my cpu is pegged at 100% most of the time. Task Manager shows srvchost as being a main culprit of course but also system interrupts. I have a Biostar socket 478 MB with Via chipset. I have tried to find Windows 7 drivers for this but when I download and try to install what VIA/BIOSTAR say should be good for all OS's it will not load. I get a message saying can't find components for this OS. Anybody have any idea where I might find suitable drivers for the Chipset? BTW I'm not using the integrated graphics on the board but have a radeon 4500 pci-e card.
