  • Diffing file contents

    - by PHeiberg
    I have two plain text files, each file is containing a list of strings sorted alphabetically with one string per line. I want to diff the files and have an output of all strings that exist only in file2. Preferabbly I want the operation to be possible without any 3rd party tools, or with a minimum of installations of tools that is "normal" to find in a windows command line environment, such as GNU Diffutils, Powershell, etc. The output should be in text form (file or as command line output). Example: File 1 contents: A C D File 2 contents: A B C E Result wanted: B E

  • ATI Radeon 5850 I cant seem to get 3 monitors up at the same time. 2 Monitors and a HDTV but still.

    - by Jan
    Ive just bought the top end ATI Radeon card with 2 normal monitor ports and a HDMI. The idea was to continue using my dual screen setup as always and to use the last plug, the HDMI on my TV. I got a new 52 inch HD TV with all the necessary bits. This should work fine. But.. in Display Properties I still get only my 2 monitors up as options. Not the Digital TV. When I unplug 1 monitor and restart the computer, I get the TV and the other monitor. But never all 3 at the same time. Why is this ? Where can I go to tell it that I need all 3 screens at the same time. Also I get a message saying my gfx card also gives sound through the HDMI cable.. But the TV tells me its recieving a sound format that it does not understand. Any ideas on that too while were at it ?

  • QuickTime X incorrect aspect ratio for H.264 video

    - by Adam Robinson
    I'm running Snow Leopard and have a serious issue with QuickTime X. I have a Samsung HMX-H100N/XAA camcorder that records H.264 video in either 720p or 1080i. In either of these resolutions, QuickTime X (and, by extension, all QuickTime-associated applications like FCP, iMovie, etc.) displays an incorrect aspect ratio for all video produced by this camcorder. For example, 720p video is reported as being 1280x720 in the movie inspector (which is normal), but the displayed size is always at an aspect ratio of something like 63:20 (never heard of such a ratio) with sizes like 1700x539. If I open the video in QuickTime 7 player on the same computer, it is displayed correctly. If I process the video through something like MPEG Streamclip to transcode it, it displays correctly. As it stands right now I have to transcode all of my video in order to use it in any iLive (or other QT-based application) unless I want it to look ridiculous. I've tried installing Perian, but that seemed to have no effect.

  • How to install OSX into VirtualBox on a Macbook Air using Apple's Reinstall USB

    - by eug
    I'm currently dual-booting OSX and Ubuntu on my Macbook Air, but it'd be nice to run OSX within Ubuntu via VirtualBox. This seems possible using VirtualBox and is legal - there's even a post on an Oracle blog describing this: http://blogs.oracle.com/karim/entry/installing_mac_os_x_in. Actually, I've read elsewhere that it's only legal with OSX Server, but can't find a reason why it'd be illegal with normal OSX - please let me know if you think otherwise. The problem I have is that a MacBook Air doesn't come with a bootable DVD, but with a "Reinstall Drive" which is a USB stick that comes up as a CDROM drive. It doesn't seem to be ISO9660-formatted though but has an Apple partition table, with OSX installed on an HFS partition. refit says that it has a "boot.efi" as well. I don't know Apple booting/partitioning very well and would really appreciate some advice on how to convert this USB into an ISO or boot it in VirtualBox some other way.

  • OOM-Killer called every now and then..

    - by SpyrosP
    Hello there, i have a dedicated server where i've installed apache2, as well as Rails Passenger. Although i have 2GBs of RAM and most times about 1,5GB is free, there are some random times when i lose ssh and generic connectivity because oom-killer is killing processes. I suppose there is a memory leak but i cannot find out where it comes from. oom-killer kills apache2, mysql, passenger, whatever. Yesterday, i did a "cat syslog | grep -c oom-killer" and got 57 occurences ! It seems that something seriously destroys the memory. Once i reboot, everything comes back to normal. I suspect that it can be related to Passenger, but i'm still trying to figure it out. Can you think of anything else, or do you have anything to suggest that will make the leak identification procedure easier ? (i was even thinking of writing a bash script, to be run with cron for like every 5 minutes).

  • How to automatically show USB camera or memory stick contents in Icewm?

    - by darenw
    I normally use a very lightweight Linux setup. No desktop like Gnome or KDE, just Icewm as the windows manager and nothing else that normal users might consider essential. Well, I do need a file manager - I use Thunar. Recently I've been trying Gnome. Whenever I shove a memory stick into a USB port, or connect my digital camera, it can automatically pop up a file manager showing all the goodies on that device. KDE does this too. I like this. Although quick at the command line, I like not having to go sudo to mount the device and all that. If I want to stick with a lightweight setup using Icewm+Thunar, is there something non-huge I can install to make external devices fire up a Thunar window, or otherwise make access to the contents brainlessly easy?

  • How do I share a complete XP disk so it can be seen from a Windows 7 system?

    - by Ian Ringrose
    This should be easier! (both computers can see the internet etc so I know the network it’s self is working) I have a normal home network with a Windows XP machine on it and the new Windows 7 (64 bit) machine. So I can transfer the files to the new Windows 7 machine, I wish to share the complete disk (and all files) from the Windows XP machine and access them from the Windows 7 machine. Is there a step by step set of instructions for doing this anywhere? So fare I have: put both computers into the same workgroup put the windows 7 machine into work network mode so it can see the XP machine in the work group shared the XP disk as read only But when I try to access a lot of the folders on the XP disks, I am told I am not allowed to access them. (I was not asked for any passwords by the windows 7 machine when I accessed the XP machine. The XP machine just has its default account with no password set on it)

  • Is there any way to disable certain keyboard shortcuts in Windows 7?

    - by matt b
    There is something going on with my Windows 7 machine where attempting to unlock the workstation the Win key is "stuck" on (not quite sure what is causing this). What this causes is that when I am entering my password, which contains a "p", Windows thinks I am pressing Win + p as if I want to change my display settings to enable a projector. This is highly annoying when attempting to unlock my workstation! The workaround I've found to "unstick" the Win key is to cycle through the projector/display settings once, land back on the original value, and then resume entering my password as normal. But is there any way to completely disable the shortcut for Win + p ? In all likelihood I will never hook up a projector to this machine, or on the once-in-a-lifetime chance that I do, I am more than happy with having to go into the Display Settings myself.

  • 10 gigabit or 1 gigabit switch

    - by Guntis
    We are planning to move mysql to dedicated box. At this moment we have web servers and mysql is running on each. Question is: cheaper is to buy 10G switch and put 10G network card into mysql server. Or buy normal gigabit switch and connect mysql box to switch with multiple network cables. In 1G scenario then we give each web server different mysql IP address. I don't think, that mysql box with one 1G link is enough to to satisfy multiple web box mysql traffic. At this moment we have 3 servers witch are running mysql/web. Plan is to add fourth server for mysql only. Thanks. Edit: if we buy 1G switch with mini-GBIC ports. Can we put in mini-GBIC 10G connectors and then connect mysql box to that port?

  • How can I check whether a volume is mounted where it is supposed to be using Python?

    - by Ben Hymers
    I've got a backup script written in Python which creates the destination directory before copying the source directory to it. I've configured it to use /external-backup as the destination, which is where I mount an external hard drive. I just ran the script without the hard drive being turned on (or being mounted) and found that it was working as normal, albeit making a backup on the internal hard drive, which has nowhere near enough space to back itself up. My question is: how can I check whether the volume is mounted in the right place before writing to it? If I can detect that /external-backup isn't mounted, I can prevent writing to it. The bonus question is why was this allowed, when the OS knows that directory is supposed to live on another device, and what would happen to the data (on the internal hard drive) should I later mount that device (the external hard drive)? Clearly there can't be two copies on different devices at the same path! Thanks in advance!

  • How to get HTTP preseed to work correctly on Ubuntu 10.04 LTS (Lucid)?

    - by netvope
    Installation media: ubuntu-10.04-desktop-i386.iso I tried a lot of different boot parameters, but either the installer ignored the preseed configuration, or it boot itself directly as LiveCD. An example of the boot parameters I've tried: auto url=http://mydomain.com/path/preseed.cfg boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash -- If I remove only-ubiquity, it boots as a LiveCD. If I remove boot=casper, it won't boot. If I add vga=normal locale=en_US console-setup/layoutcode=us console-setup/ask_detect=false interface=auto, it still can't do automatic install. If I remove auto, it's the same. What is the correct boot parameters for launching such an installation? From the apache log of the server hosting preseed.cfg, I see that the installer has no problems fetching the preseed file. My preseed file is almost identical to the one at https://help.ubuntu.com/10.04/installation-guide/example-preseed.txt. Moreover, I have run debconf-set-selections -c preseed.cfg to ensure that the preseed file is correct.

  • Excel 2007 Save as PDF with pagesize/pagewidth auto or not breaking Excel lines.

    - by mxg
    Hi everyone! I tried to export an Excel file into PDF, but it looks horrible. I need at least that one row form Excel to be saved into a one row in PDF. I know that it is not so simple, because Excel does no have any page size. At least, they could make some estimations. Can anyone recommend me how to save in MS Office an excel file into PDF, to have a normal look? Thanks in Advance!

  • Web service not accessible from behind corporates firewalls - how come?

    - by Niro
    We run a Saas serving a widget which is embedded in customer websites. The service include static javascript code hosted on amazon S3 and dynamic part hosted on EC2 with Scalr (using scalr name servers). We received some feedback from users behind corporate firewalls that they cant access our service (while they can access the sites including the widget). This does not make sense to me since the service is using normal http calls on port 80 and our URL is quite new without any reason to be banned by firewalls. My questions are: 1. Why is the service is not accessible and what can I do about it? 2. Is it possible that one of the following is blocked by corporate firewalls: Amazon s3, the dynamic IP address provided by amazon, Scalr name servers. Any other possible reasons, way to check them and remedies for this? Thanks!

  • remote desktop network failed connection

    - by tbischel
    I was trying to create a remote desktop connection from Windows XP to my Windows Vista Ultimate Addition machine at home. This normally works fine. Today after my connection was dropped, I tried to reconnect to my machine. It brings me to the normal startup screen, but when I tried to log in, it gave me the message "This network connection doesn't exist". This doesn't make much sense, as I have reached a Windows style login screen already. My connection returned later that day, but I'm curious as to what happened. Anyone see this before?

  • How to install Windows7 on Hitachi HTS545050a7e380 harddrive?

    - by wurlog
    I have a Samsung NP530U3B with a Hitachi HTS545050a7e380 Harddrive. In the Bios it shows as one drive Hitachi hts545050a7e380 When I try to install Windows 7 it show 2 drives in the setup Drive 0 with 15 GB Drive 1 with 460 GB Guess it is a hybrid of SSD and normal harddrive, right? I tried to install it on the second drive, but after restarting it goes back into the beginning of the Windows 7 installation. The installation routine automatically activated a 100 MB partition on Drive 0. I guess for the bootmanager. Second try: Installation on the 15GB drive. The same. After reboot it wants to install win7 all over again. If I remove the USB Stick I get the message "Missing operation system" Any ideas?

  • Laptop harddisk produces clicking sound

    - by Alfred James
    This happens when I am booting up into windows, shutdown or things in which I access the harddrive excessively. It doesn't happen all the time. I have checked it with "Crystal disk Info" and it displays no problem, and shows HDD to perfectly fine. Should I be worried about my HDD? I have Hitachi HDD in laptop. Some times my harddrive temps reach upto 43C while watching movies or playing games. What are the normal temps, which are safe for HDD to operate and increase the lifetime of HDD. Thanks

  • Skype 2.1beta for Linux and sound quality

    - by vava
    I've been using Skype 2.1beta for Linux with my bluetooth headset and quality of the sound is just awful. But not always though, if I call echo service, quality is acceptable, but when I call real people there's echo, sound is crippling, there's pauses, voice is unrecognizable, all sorts of quality problems in one call. If I use newest Skype under WIndows with the same headset to call to the same people, quality is more than normal. So, is there some settings I can tweak, like tell Skype which codec to use or maybe there's noise cancellation plugin for PulseAudio I can use or any other system setting I can try to play with?

  • Computer freezes for 2+ seconds, mouse still moves

    - by xsaero00
    I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause. System: CPU: i7-920 Memory: 12G of Patriot DDR3, 6 modules OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome Main board: Asus P6T Video: two Nvidia 9500GT connected to three displays I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there. Any ideas? Where should I start looking?

  • Linksys EA3500 : use WAN port as WAN + LAN possible?

    - by Dough
    I'm waiting for deliver of a Linksys EA3500 router. I was wondering if it was possible to get the WAN port act as normal WAN port (Internet IP) + LAN switch ? My problem is that my Internet box is in a room with NAS and PC, and the router will be in another room with TV, PS3 and PC. The Internet box have a 4 port Gigabit switch so one cable will plug from there to the router's WAN in the other room. The router will get the Internet IP from the Internet box, but will it be possible to have private network through this link too ? I could have a first network between the Internet box and the router, and another network form router and devices but that will do double NAT for nothing... Thanks for reading me and your help !

  • Unexpected network traffic?

    - by robwalker
    My internet connection is via a fixed wireless connection using a 900MHz Motorola Canopy module. The router reports a fairly consistent 32-64Kbps of incoming traffic on the WAN port. When I attached a PC directly to the port and run Wireshark, I get a dump showing a lot of chatter from other machines that I presume are connected to the same tower. This didn't include end-to-end traffic, but was there were a lot of ARP requests, SSDP traffic, ICMP and other network discovery type stuff. Is this 'normal' or does it suggest a misconfiguration somewhere? As far as I can tell there is no need for my modem to be receiving any of this traffic (other than wanting to know what the names of my neighbours machines and printers are!) Since the internet connection is slow at the best of time, having this amount of background noise seems very wasteful.

  • Can't get any SMART or temperature data from HDDs

    - by Regs
    I have a PC with recently installed Gigabyte GA-X79-UD5 MB. I've encountered some weird problem with getting SMART data or temperature for HDDs. Every single tool I've tried in Windows 7 just can't get any data (HDTune, AIDA64...). I was suspecting that SMART feature is disabled in BIOS but it's seems like there is no such option in BIOS settings. I've even tried to update BIOS but still no luck. Same issue with both controllers on that MB (Intel and Marvell). It seems unlikely that both controllers end up with exact same issue. Both controllers are working in AHCI mode. Is there anythig that can interfere with getting SMART ant temp data from HDDs? Or is there any way to check that it's actuall MB issue? Is it even possible that it is hardware issue since all HDDs seems to work normal despite the fact that I can't get any temperature or SMART data from it.

  • VPN trace route

    - by Jake
    I am inside an Active Directory (AD) domain and trying to trace route to another AD domain at a remote site, but supposedly connected by VPN in between. the local domain can be accessed at 192.168.3.x and the remote location 192.168.2.x. When I do a tracert, I am suprised to see that the results did not show the intermediate ISP nodes. If I used the public IP of the remote location, then a normal tracert going through every intermediate node would show. 1 <1 ms <1 ms <1 ms 192.168.3.1 2 1 ms <1 ms <1 ms 192.168.3.254 3 7 ms 7 ms 7 ms 212.31.2xx.xx 4 197 ms 201 ms 196 ms 62.6.1.2xx 5 201 ms 201 ms 210 ms vacc27.norwich.vpn-acc.bt.net [62.6.192.87] 6 209 ms 209 ms 209 ms 81.146.xxx.xx 7 209 ms 209 ms 209 ms COMPANYDOMAIN [192.168.2.6] Can someone explain how does this VPN tunnelling works? Does this mean VPN is technically faster than without?

  • What are the benefits of running a app server in user space, like Unicorn, as opposed to as sudo?

    - by dan
    I've been using Phusion Passenger + Rails/Sinatra for a lot of projects. Passenger runs under the main Nginx or Apache process. But I'm interested in Unicorn, partly because it runs in user space. You just set up Nginx to proxy_pass requests to a unix socket that is connected to Unicorn processes that you fire up under a normal user account. Is there anything to be said as far as advantages and disadvantages of these two alternative approaches to running an web app? I mean in terms of ease of administration, stability, simplicity, etc.

  • How can I get the real Emailaddress of a recipient?

    - by Boas Enkler
    a user in out Company has 2 mail-addresses on one Exchange-Mailbox. e.g test@... and test1@... the Primary SMTP-address off the Mailbox is test@. If I send a message to test1@, load it using EWS and parse through the TORecipients-Collection there is exactly one emailadress. But the mailaddress EWS gives to me is test@... and not test1@... where I sent the mail. My problem is, that all mails sent to test@ should be imported in our CRM using my program. All mails sent to test1@... must not be imported. In real life both mailaddresses are from my Boss. One is used for normal purposes the other one is for confidential e.g. from his lawyer. Does anyone know how I can get the real-emailaddress the message was sent to?
