    - by pedro
    I want to split a file into multiple files with at most 25 lines each. I'm using this: split -l 25 /etc/adduser.conf > /home/ubuntu/PL/trab3/rc_ But I do not get the files I expect. How can I get files with filenames like rc_01, rc_02, etc.?

  • Partition External Harddrive already using Time Machine?

    - by Wex
    I have a 1TB external that I've used to backup my Mac for the past year using Time Machine. Unfortunately, my hard drive is getting close to full, and I'd like to move some of the stuff off of my Mac onto the same external drive. The problem is that the external drive is already full with my Time Machine Backups. I'd like to partition 750GB to the Time Machine Backups, and save the other 250GB for personal use. Is there any way I can go about this without corrupting my current backups? I'm willing to delete some of the older backups if necessary; again I'm just worried about corrupting the data.

  • Separate computers in my apartment can't communicate to each other?

    - by Razor Storm
    In my apartment, the management provides the building with a network connection. I have my computer plugged into the ethernet coming out of the walls, and my friend who also lives in the apartment building has his computer connected to a separate ethernet jack. As far as I know our two computers are not within a LAN, and ipconfig shows that we only have external ip addresses. The problem, then, appears when we attempt make direct communication between our computers. I have some hosting server set up on my machine, and my friend is unable to connect to it via my ip address. Other people who do not live in the apartment can connect fine. Ethernet adapter Local Area Connection: IPv4 Address. . . . . . . . . . . : 204.29.113.41 Subnet Mask . . . . . . . . . . . : 255.255.254.0 Default Gateway . . . . . . . . . : 204.29.112.1 His ip: 204.29.113.104 Using a fulltunnel vpn doesn't help.

  • Won`'t read Unicode characters over NFS mount ?

    - by Julz
    Hello, I'm getting this strange issue when trying to play mp3's containing unicode characters ( accents ) over an NFS on OSX, it's all good over AFP, but I'm setup with NFS because it's a linux server on the other end . This is my disk utility setup : nfs://192.168.1.112/Music advanced mount parameters : -P , nolocks nosuid The strange thing is that I can see those files in the finder ( with the accents .. ) but I cant play them !! So Im wondering if it's an unicode issue, since I can see the files properly or a permission issue since I can't play them, but them it wouldn`t make sense that I can't play ONLY the files containing accents .. help ?? Thanks

  • Tutuorial for Quick Look Generator for Mac

    - by vgm64
    I've checked out Apple's Quick Look Programming Guide: Introduction to Quick Look page in the Mac Dev Center, but as a more of a science programmer rather than an Apple programmer, it is a little over my head (but I could get through it in a weekend if I bash my head against it long enough). Does anyone know of a good basic Quick Look Generators tutorial that is simple enough for someone with only very modest experience with Xcode? For those that are curious, I have a filetype called .evt that has an xml header and then binary info after the header. I'm trying to write a generator to display the xml header. There's no application bundle that it belongs to. Thanks!

  • Crystal Reports 8 - Error 533 PESStartPrintJob

    - by Federico Giust
    We have on the company I work for an application built in Delphi V with Crystal Reports 8. We all know that Crystal & Delphi can be temperamental sometimes and the worst thing is, nearly no detail on the error. Also there is a big lack of documentation on the web about this. There's lot of people with similar issue but no solution. The error I'm talking about in particular is the one on the image below. This happens when trying to print any Crystal Reports on screen. This has happened sometimes in the clients computer and it was hard for us to replicate on our environment. Since it's an old version of Crystal it is very hard to find any helpful documentation to know the exact source of the problem.

    I would like to change the name/ssn/tax information that is currently signed up with the iTunes Connect account. Basically I want to transfer the account to a different person. I know you need to contact them directly and you can't do it online, but I'm wondering how difficult it is to do? And what are the chances that Apple will do this for me?

  • MS Access split database queries

    - by Lance Roberts
    When the frontend of a MS Access db queries a MS Access backend on another machine over the network, does it pull in the whole table/database/file, or does it have some way of extracting just what it needs from the backend, thereby lessening network load.

Later I deleted the partition, but when I restart the macbook it kept telling that "No bootable device found" even after deleting the partition, I'm expecting it to boot directly to Mac OSX. Is there any solution to fix this problem?

  • Show the number of messages within a group in Outlook 2010

    - by Brendan
    In outlook 2010 I am unable to show the number of messages within a particular group. For example, I categorise my messages and then when I sort by category, there is no way to show the number of messages within that(those) category(ies). Previous versions of outlook would do this by default, but I am not finding the setting to do this in Outlook 2010. If it isn't possible, is there anything method to count those messages within a group/category easily?

  • I/O APIC on Virtualbox

    - by RidDeBakTiYar
    I'm trying to use the PIT to do APIC timer calibration, and I want to use the PIT through I/O APIC instead of PIC. On Bochs I get interrupts from the PIT at the asked frequency from the I/O APIC, while on Virtualbox I can't receive a single interrupt. It must be an I/O APIC configuration problem because as I unmask the first PIC entry, the IRQ fires. However that's not what I want. Can you imagine any possible condition that wouldn't make Virtualbox fire the IRQ? I'm not assuming single I/O APIC configuration (even though Virtualbox has only 1). I'm not assuming identity mappings between ISA IRQs and I/O APIC GSIs (using ACPI MADT table to get I/O APIC base address and Int override). I'm setting the Trigger Mode and Polarity bits correctly (on Virtualbox they are set as '00 - default' which means edge high right?). I'm putting the BSP APIC ID into the Destination field (using Physical destination) and vector 0x20. Being the BSP APIC ID 0 on Virtualbox, it ends up with 0x0000000000000020 written to the IOREDTBL. And, just in case I'm getting the wrong values from the Interrupt Override descriptor, I'm setting this value to all the IOREDTBL entries (I know this is very very bad, and it wont be kept as I understand what's going on). The only thing I didn't check out is Local APIC configuration. Actually I'm not writing any value to the BSP LAPIC. Just reading the APIC ID and using it to boot APs through IPIs. And obviously I'm setting bit 11 in the IA32_APIC_BASE MSR to enable the LAPIC. Any ideas? Thanks in advance.

  • Looping through a batch file only if the response is "everything is okay"

    - by PeanutsMonkey
    I have a batch file that loops through the contents of a directory and compresses the files in the directory as follows; for %%a in (c:\data\*.*) do if "%%~xa" == "" "C:\Program Files\7-Zip\7za.exe" a -tzip -mx9 "%%a.zip" "%%a" Seeing that I am using 7zip to compress the file, it returns the message "everything is okay" if it has successfully compressed the file and it then moves onto the next file in any. What I would like to do is the following; Only move to the next file if the response is "everything is okay" If the response is anything but "everything is okay", the error is logged Since an error has occurred, it attempts to compress the file again Once when it has succeeded i.e. "everything is okay" it goes to the next file Steps 3 & 4 only occur a maximum of 3 times before it gives up and moves onto the next file. How can I achieve this?

  • BIOS corrupted? How to proceed? Acer Travelmate 290

    - by dtlussier
    I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

  • The cleaner way to upgrading a Mac

    - by AngryHacker
    This page list a way to do a clean install of Snow Leopard without loosing any of your settings. This sounds pretty darn good since my mac did get a bit slower over time. The method basically involves copying your existing drive to an external one, then doing an Erase and Install from the installation DVD. After the installation, supposedly, I'll be presented with an option to migrate settings from another Mac. I am not all that familiar with the Mac, hence what is probably a simple question. With this migration option, will I be able to copy over all my applications or will I have to reinstall them from scratch?

  • Torrentflux broke after upgrade

    - by parker.sikand
    A working torrentflux setup seems to have gone broken after upgrading PHP to 5.3 and Postrgres to 9.2beta3 on a FreeBSD 8.2 server. The login screen will show up fine, but after clicking the login button, I get an error : Fatal error: Call to undefined function pg_escape_string() in \ /usr/home/parker/tf/html/inc/lib/adodb/drivers/adodb-postgres64.inc.php \ on line 241 Seems to be an error with PHP and the pgsql php package. The phppgsql package itself is not totally broken because I'm using it to host database driven apps on this server. This is the first and only error I'm seeing from it. How might I go about fixing this problem?

  • windows 8.1 does not boot after CHKDSK command

    - by sepehr
    I had problem with Windows 8.1 high Disk usage so in order to solve , searched forums. A voted answer suggested to use CHKDSK command as follow: run command prompt and as administrator type code snippet below: CHKDSK /f /v /b C: (I can not remember accurately) CHKDSK printed : can not run CHKDSK right now , would you like to schedule C drive to be checked next time windows starts? (Y/N) my response was "Y" ,please ! Following this suggestion not only didn't solve my problem as expected but also added another one ! The next time system booted, after windows authentication I just could see a black screen and mouse pointer. So I force shut downed the system and tried to start windows again. This time , windows got stuck in Scanning and Repairing on 22% for around 3 hours so I got tired and forced shut downed again. is CHKDSK source of Scanning and Repairing problem or they are discrete ? is there any hope to overcome this problem without re-installing windows ? can any one else run CHKDSK on newer versions of windows without problem? is CHKDSK effective but inefficient ?(it finally get to end but will take a long time) If yes, how much time does it take? I also have Linux Ubuntu 14.04 installed along side windows.

    What kind of executable files can run on windows xp-7? I know of PE, but I don't know if there are any others. I'm also interested in knowing different kinds of interpretive executables, like a java program and such. Thanks. I'd also like to know what extensions they use, like PE uses .exe and .dll.
