  • osx bash grep - finding search terms in a large file with one single line

    - by unsynchronized
    Is there simple unix command line i can enter which lets me isolate say 512 bytes either side of a search term, even if there is only one "line" in a very large text file? Ok, this should be easy. Famous last words. I'm not that familiar with grep, but it seems it is mainly used to filter out lines in the input that contain search terms. I have a very large json file that I downloaded that i want to search for a particular term. before you click the link - it's over 244MB so be warned - it is from the internet wayback machine and contains lists of zip files of archived photos. i am trying to find mine. Their web interface is broken, so i found the json file that they make public here - it's the last one on the list. when i grep looking for my username, it finds it, but proceeds to dump that line to the console. the problem is that line is 244MB long, and it's the only line in the file. i tried using less, but could not get that to do much - it's very slow, and seems to have the same issue. is there simple unix command line i can enter which lets me isolate say 512 bytes either side of a search term?

  • Install windows XP alongside Windows 8

    - by user01
    I have a 64 bit (AMD)CPU but it has 32 bit Windows 8 installed. Could I somehow trickily install another Windows XP 64 bit alongside to that ? I want to do this because I almost never use the Windows 8 apps & majorly use this machine for java development. So I would like to run a lightweight OS implementation. Additionally, With 64 bit version of Windows XP, I would be able to take advantage of my 64 bit CPU. So, how do I do it? (I hope there's some way to do this:)

  • Restore Windows 7 bootloader after Windows 8 install

    - by JMK
    I have installed Windows 8 onto a partition after Windows 7, and when I turn my PC on, Windows 8 basically loads completely, and then I get the option to choose my OS. If I select Windows 8, I go straight to the lock screen, if I select Windows 7, my computer completely restarts and then boots into 7. I want to use the Windows 7 installation DVD to restore the Windows 7 bootloader using the method described by the How To Geek but I am worried that if I do this, Windows 8 won't boot. Can anybody advise on whether or not this will work, and if not how can I go back to selecting the OS right after the BIOS loads?

  • Ruby on rails gems and win 7

    - by cbrulak
    I have a networked home share (at work). This is my HOMEPATH,HOMESHARE,etc. When I installed the rails gem and other the .gems folder was created there (which is on a network drive) and consequently any code that needs a gem or a gem lookup is slow. And I'm wondering which environment variables need to be corrected. I've googled this but most results are dealing with cygwin so any ideas? Thanks

  • MsMpEng.exe (Windows Defender?) uses a lot of CPU at startup and runs two instances on a single core

    - by dlamblin
    I'm using Windows XP Professional SP2 on a single core AMD64 processor, and I've got two instances of MsMpEng.exe starting up when I start up and log in. They use 64MB and 32MB of ram and 140MB and 80MB of virtual memory, and fluctuate around 80% CPU usage for about 5 minutes at start up. They are (I read) associated with Windows Defender, but I'm concerned about: There's two of them, everything I read generally has only one reported. They might be scanning each other, and I want that to stop. They might be getting scanned by avgrsx.exe (AVG Free 8) (uses about 16Mb v ram) They might also be scanning moe.exe (assosciated with ms live mesh, which I'm considering getting rid of) Lastly I have Microsoft Security Essentials. I don't know the process name associated there. The main concern of mine (apart from the double instances) is that these are all trying to prioritize scanning each other at once except maybe moe.exe. This might seem legitimate but is likely a useless drain on resources. Have I made a mistake in having all of these installed, or is there a way to inform them not to do whatever they're doing that's taking about 5+ minutes at start up? [I also have Google Desktop, but I'm keeping that.] Comment if none of this makes sense to you.

  • Disabling a touchpad in Windows

    - by Shamaoke
    I want to permanently disable a touchpad in Windows running on my laptop, since firstly, I use a mouse, and secondly, when I work, I often touch it accidentally what causes definite inconviniences. I tried the following approaches to disable it but with no result: Turned it off through BIOS — there's no such function there; Turned it off through the touchpad configuration utility — there's no such function there; Turned it off through the device manager — the disable button is inactive; Turned it off through a hotkey (Fn + F1 in my case) — the hotkey doesn't work; Uninstalled the proprietary driver — Windows automatically downloaded the standard driver; Uninstalled the standard driver and turned off the automatic driver download function (Win + R ? "systempropertiesadvanced" ? Hardware ? Device Installation Settings) — all the same, Windows downloaded and installed the driver. How can I disable a touchpad? Windows 7; the Alps touchpad.

  • Ctrl+Z and fg to append commands

    - by avilella
    I would like to know what is the behaviour of Ctrl+Z and fg in bash when wanting to append commands to be executed after a running command has finished. For example, in the sequence for commands below, I would expect the console to display "1", then "2", then "3", then "4", but I only get the last command, echo 4, after sleep 30 finishes: avilella@magneto:~$ sleep 30 && echo 1 ^Z [1]+ Stopped sleep 30 avilella@magneto:~$ fg && sleep 5 && echo 2 sleep 30 ^Z [1]+ Stopped sleep 30 avilella@magneto:~$ fg && sleep 5 && echo 3 sleep 30 ^Z [1]+ Stopped sleep 30 avilella@magneto:~$ fg && sleep 5 && echo 4 sleep 30 4 Any ideas?

  • WinPcap/Wireshark install: where is packet.ddl?

    - by Annonomus Penguin
    I have Wireshark installed, and I'm getting this error: The NPF driver isn't running. You may have trouble capturing or listing interfaces. I realize this is something to do with WinPcap. It's not in control panel, as the FAQ states it should be. I've tried installing it, and it says that there is a previous version installed. This leaves me to believe this is the problem: To be absolutely sure that WinPcap has been installed, please look at your system folder: you should find files called packet.* and wpcap.dll. Please check the file dates: these should be compatible with the WinPcap release dates. We've had reports of trojans or other malware that silently install the WinPcap driver, NPF.sys. If you've been infected by them, you'll probably see the driver file in Windows\System32\Drivers, but no entries in the "Add or Remove Programs" applet and no dlls. I've searched my hard drive, but the only path is this: C:\Windows\SysWOW64\packet.dll Is this the file they are talking about? Should I delete this file? I'm not quite sure, so I thought I'd verify that this file is the right one.

  • Processor speeds on my machine don't live up to manufacturer hype

    - by atch
    Why am I not seeing the promised speed claims of processor manufacturers on my computer? Producers of processors claim that their product can perform so many thousands (or millions) of operations per second. And yet on my machine (4GB, 3500hz), the typical program (Word, Visual Studio etc.) takes at least 10 seconds to start. I've formatted my hard drive and ticked all the necessary boxes to optimize my machine and yet I'm not seeing the promised speeds. Say it takes Outlook ten seconds to load. How many millions of operations does it really go through in order to start up?

  • Using themes in visio

    - by JohnW
    I'm looking for a good reference on how to properly use themes in Visio. Here's been my experience so far: Create a flowchart diagram - nothing fancy, just all black & white. No formatting applied to any object. Select & apply a theme to the diagram. Despite the theme showing a set of matching colors, the diagram now has a single color applied to all objects. Right-click the object, format, fill, and pick a color from the set of matching theme colors. End up with an amalgamation of the original theme color I picked (blue) and the new color (green). With enough 'playing' with the object, I can get it to look OK, but it feels like I'm missing something, that it shouldn't be this hard to get a matching color. Any advice would be appreciated. :)

  • Dell XPS m1530 system cannot boot need 130w or greater

    - by KPS
    I have a Dell XPS M1530 and I lost my old AC adapter but ordered a new one. For the longest time it always had a battery charge so I was able to boot into the OS but now it is completely dead. I have a generic charger that slowly charged the laptop when it was in the OS but does not when the computer is off. When I boot up I get the following error: The AC power adapter type cannot be determined. The system can only boot with a 130 W power adapter or greater. Strike F1 key to shutdown. I cannot even enter the BIOs setup screen or boot menu, is there a way around this? I heard from the local tech that Dell has a special feature to boot from thumb drive before getting past the initial logo. I am doing my best to avoid purchasing a new charger since it worked just fine when the OS was running, I am hoping to get this thing going. Is there a way to charge the battery externally? Thanks in advance for any help!

  • All files trying to start in Notepad

    - by Jormal
    This question has been asked, but the solutions given were worthless to me because ALL files are trying to open in Notepad. I mistakenly associated all exe files with Notepad and everything is trying to open within Notepad now. That includes regedit, so suggesting I use regedit to doctor files does not work (cmd window will not open from Winkey + R - Run). It also includes any program I download to fix the issue. I also can not right click and choose Open With because that is not a given option when right clicking on a majority of files, at least none of the exe files I want to start. Yes, I tried it on the program files, not the shortcut. I also can not use System Restore because it, too, tries to open in Notepad. I've been banging my head uselessly on this for hours. Could someone help me out?

  • Windows 8 Restore Problems

    - by Joe
    I created a Windows 8 system image backup on a separate drive before I installed Linux, and during the Linux installation process I accidentally wiped out Windows. I now want to restore my Windows 8 backup that I have on the separate drive. I created a repair USB stick and I followed the directions according to this article. After selecting the image on the hard drive, I get this error: "To restore this computer, Windows needs to format the hard drive." I don't know what this means! The drive partitions are different now then they were when I backup up, so I don't know if that matters. I re-installed Windows and I can restore my files from this backup, but I don't think this covers the registry, etc. I want a full restore. Does anyone know how to fix this problem, or how to restore in a different way? Thanks!

  • Working with barcode fonts in Word

    - by Bob Rivers
    I need to create labels in Microsoft Word 2010 with numbers encoded as barcodes. The barcode's format (ean, code39, upc, etc) does not matter. I have downloaded a barcode conversion font that I found at this site. When I type the number that I want and then I format it with my new font, it produces a barcode. I then print it on an OKI laser printer (1200 dpi). The result seems to be fine, at least for common people. But, when I try to scan it, nothing happens. I tried both with a barcode scanner and a data collector, but neither of them read the barcode. My barcode scanner is working fine, because I can read commercial barcodes printed on products. Does anybody have any advice? How do I do this kind of stuff? I want to do it using Word because I will generate labels using Mail Merge. Therefore using external programs aren't option for me.

  • Hiding a file or data from being accessed unless on scheduled days [closed]

    - by gkt.pro
    Possible Duplicate: restricting access to volumes disk even for admin account windows How to restrict use of a computer? I want to limit my access to some data and what I want is that I should be able to access the data only on certain days of the month (e.g., every 3rd day). Is there any way like encryption or some utility to allow me to only access data on specific days? One idea that I was thinking of was to encrypt the data and store the password (will be complex and long so that I couldn't remember it right away) on some website which would then email me back the password in future on those specific days.

  • Windows 7 fails to install on KVM with qemu

    - by kief_morris
    I'm trying to install Windows 7 on a virtual machine on my 64 bit Ubuntu Karmic box. I get to the point of selecting my language settings and clicking 'install now', but a short while later I get a blue screen of death. I've tried a few variations, including using the 32 bit (fails very quickly). The virt-install command I've tried includes this: sudo virt-install --connect qemu:///system -n ksm-win7 -r 2048 \ --disk path=/home/kief/VM-Images/ksm-win7.qcow2,size=50 \ -c /var/Software/Windows7/Full/64bit/SW_DVD5_SA_Win_Ent_7_64BIT_English_Full_MLF_X15-70749.ISO \ --vnc --os-type windows --os-variant vista --hvm The limited info I could find suggested that 'vista' should work as the --os-variant, I haven't found any values specific to windows 7. Here's my blue screen: I've found very little by Googling, so I'm guessing this isn't a case of KVM simply not supporting Windows 7. Thanks for any help. Update: I have been able to successfully create a Windows 7 VM using the graphical "Virtual Machine Manager" app, although I don't really understand the cause of the problem with the VM created with virt-install. Comparing the configuration files under /etc/libvirt/qemu provides some clues, although I don't know enough to interpret them properly. The interesting differences in the two VM configurations are: --- win7-virt-install.xml +++ win7-vmm.xml -<domain type='qemu'> +<domain type='kvm'> @@ -21 +21 @@ - <emulator>/usr/bin/qemu-system-x86_64</emulator> + <emulator>/usr/bin/kvm</emulator> @@ -23 +23 @@ - <source file='/home/kief/VM-Images/ksm-win7.qcow2'/> + <source file='/var/lib/libvirt/images/ksm-win7x64.img'/> I'm not sure if this means the working VM is not using qemu at all, or if there is some other difference in the way it's used with kvm. Update2: So I've answered my own question (mostly) below. A KVM VM needs to use KVM's own CPU emulation rather than qemu's in order for me to get Windows 7 installed. I'm not sure whether there is something that can be done to get it working on a qemu-emulation CPU, or whether a newer version will support it. But at least it is possible to get it running on a KVM VM.

  • Is putting the swapfile & temp folder to ramdisk a good idea in Windows 7 64 bit with lots of RAM?

    - by Tony_Henrich
    I want my Windows to run as fast as possible. If I have 12GB RAM in Windows 7 64bit, quad core CPU, and all apps fit in memory, will the swap file ever be used for anything? The question is about if it's a good idea to put the swap file in a RAM disk. Would a RAM disk help in any way or will Windows intelligently use all the available memory for all its work? I am also thinking of putting the temp folder on a RAM disk. I know the RAM disk is volatile memory and I don't care about its content if it gets lost.

  • Is there a webproxy via email?

    - by mafutrct
    This is probably a bit weird, and I don't think it exists yet. I'm basically asking for a program that, upon receiving a request via email, downloads a html page and sends it via email, possibly changing the links inside the page into outgoing emails to this program asking for another page. This is certainly one of the most crude ways of accessing the web, and obviously fails at anything beyond the most basic stuff. But it may still be useful to those that can send email, but can't access the web due to company policy or whatever reason. In the (likely) case this does not exist, I'd be interested to write such a proxy.
