  • Rollback driver in Windows via command line

    - by ultrasawblade
    I have a remote system in which I've updated the Nvidia graphics driver, but now RDPDD.dll, which I'm guessing stands for RDP Display Driver, will not load (found this out via Event Viewer). I can use Sysinternal's Psexec to execute commands though. I'm sure something has gone very wrong and the user of this system (a CAD engineer) won't be able to use his system normally. I've tried two remote reboots and that has not resolved the issue. So I would like to use the "Roll Back" option for the Nvidia driver in the device manager. Is there a command-line way of doing this?

  • How To Create An FTP User That Has Permission To EVERYTHING

    - by Serg
    I've spent the last two hours trying to create an FTP user so I can transfer some files over to my Wordpress blog folder. /var/www/sergiotapia.me I'm using vsftpd and Ubuntu 12.04 for my FTP server and I've read tons of documentation, none of which seem to work. I still cannot log in with the FTP user, let alone test if I even have the read/write file permissions. Can a Linux guru here, help me out with a small step by step? I'm comfortable with the terminal and nano, so that's not an issue - I'll SSH into my box. Just tell me what to do and what commands to run. Specifically, this user needs to have read and write access to the /var/ folder and anything within it. I want to have 1 user that can do whatever the heck he wants on my Ubuntu 12.04 VPS machine.

  • How to reuse backup on Time Machine on Snow Leopard after a logic board change, after choosing wrong

    - by kmiffy
    After my logic board was replaced, I connected my laptop back to my network, and Time Machine gave me a popup, as shown on this thread: http://superuser.com/questions/78068/recycle-time-machine-for-new-machine/78264#78264 I misread the question and clicked on "Create New Backup" when I should have clicked on "Reuse Backup" to connect to my old backup file. How can I trigger that popup again? Turning Time Machine on and off does not work, and the instructions on forums to fix via terminal doesn't work because snow leopard is missing the fsaclctl command (and I'm also not familiar with terminal commands.) Thanks.

  • Using ROBOCOPY to MOVE data around, not copy it

    - by Nate Bross
    I have the following powershell script, which executes a few robocopy commands: ROBOCOPY.exe $q3 $q4 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $q2 $q3 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $q1 $q2 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $src $q1 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD This works fine, but it takes a really long time, I'm wondering, if there is a way that I can have robocopy do a "cut + paste" instead of a "copy + paste" so windows will move the NTFS pointer to the file, instead of actually copying all of the bits of each file?

  • Mercurial says hgrc is untrusted in Emacs, but works fine from the command line

    - by Ken
    I've got some Mercurial checkouts in a directory that was mounted by root. Mercurial is usually suspicious of files that aren't mine, but I'm the only user here, so I put: [trusted] users = root groups = root in my ~/.hgrc, and now I can use hg from the command line with no warnings or errors about anything being untrusted. So far, great. But when I try to run, say, vc-annotate in Emacs, I get an Annotate buffer that says: abort: unknown revision 'Not trusting file /home/me/.../working-copy/.hg/hgrc from untrusted user root, group root Not trusting file /home/me/.../working-copy/.hg/hgrc from untrusted user root, group root 7648'! The message area says: Running hg annotate -d -n --follow -r... my-file.c...FAILED (status 255) I don't have anything in my .emacs related to vc or hg. Other commands, like vc-diff, work fine. What am I missing here?

  • looking for information on porting Linux apps to windows

    - by claws
    Today I've encountered a very good book : UNIX to Linux® Porting: A Comprehensive Reference By Alfredo Mendoza, Chakarat Skawratananond, Artis Walker This reminded me of the thing I always wanted to know. "Porting Linux apps to Windows". I mean porting native Linux apps to native Windows with no platforms involved. If I can find any good book which explains this topic. I've lot of amazing linux command line tools in mind which needs a windows port. Please point me to relevant articles/tutorials/books. PS: please don't tell me to use linux emulation platforms like Cygwin.

  • State server in webfarm scenario?

    - by Curtis White
    This is a fairly basic question about state server but assume there are 2 servers behind a load balancer. How do I configure the session state server? So, I have machine1 and machine2. I would assume that I would need to install the state server on 1 machine only and then use the internal IP to refer to that machine. Is this correct? As oppose too, I would not install state server on both machines.

  • Type problem with Observable.Create from Boo

    - by Tristan
    I'm trying to use Reactive Extensions from Boo and am running into type problems. Here's the basic example: def OnSubscribe(observer as IObservable[of string]) as callable: print "subscribing" def Dispose(): print "disposing" return Dispose observable = System.Linq.Observable.Create[of string](OnSubscribe) observer = System.Linq.Observer.Create[of string]({x as string | print x}) observable.Subscribe(observer) The Subscribe here gives a System.InvalidCastException: Cannot cast from source type to destination type. The issue appears to be with how I'm creating the observable, but I've struggled to see where the type problem arises from. Ideas?

  • SoX on Windows 7 64-Bit Outfile Missing

    - by Christian
    I have come across the strangest problem when trying to run sox.exe on my Windows 7 installation. Whenever I try and record audio it works without any issues but it will not output an audio file. The crazy thing is that when I use the play command it successfully plays what I just recorded. Has anyone ever heard of this happening? Here are the commands (and output) that I'm using: C:\Program Files (x86)\Vox\sox-14-4-0>sox -d test.wav trim 0 00:05 Input File : 'default' (waveaudio) Channels : 2 Sample Rate : 48000 Precision : 16-bit Sample Encoding: 16-bit Signed Integer PCM In:0.00% 00:00:05.03 [00:00:00.00] Out:240k [ | ] Clip:0 Done. C:\Program Files (x86)\Vox\sox-14-4-0>play test.wav test.wav: File Size: 960k Bit Rate: 1.54M Encoding: Signed PCM Channels: 2 @ 16-bit Samplerate: 48000Hz Replaygain: off Duration: 00:00:05.00 In:100% 00:00:05.00 [00:00:00.00] Out:240k [ | ] Clip:0 Done. Am I losing my mind or is something up here?

  • Is LSB's init script function "start_daemon" really used for real daemons or should I stick to start-stop-daemon?

    - by Fred
    In the context of init scripts, according to the LSB specification, "Each conforming init script shall execute the commands in the file /lib/lsb/init-function", which then defines a couple of functions to be used when using daemons. One of those functions is start_daemon, which obviously "runs the specified program as a daemon" while checking if the daemon is already running. I'm in the process of daemonizing a service app of mine, and I'm looking at how other daemons are run to try to "fit in". In the process of looking how it's done elsewhere, I noticed that not a single daemon on my Ubuntu 10.04 machine uses start_daemon. They all call start-stop-daemon directly. Same goes for my Fedora 14 machine. Should I try to play nice and be the first one to use start_daemon, or is there really no point and start-stop-daemon is the way to go since everybody is already using that? Why is there no daemons using LSB's functions?

  • Is it possible to use different keyboards for different applications?

    - by Paperflyer
    What I would like is this: I would have two keyboards. One of them is "connected" to Matlab, the other is "connected" to my text editor of choice. This way, I could edit some script and still test some commands in Matlab without having to constantly switch between the applications. Basically, I would want to have an additional keyboard attached to my computer that solely controlled Matlab. That would be awesome! Is there any way to do this? Preferably with OSX, but it would be fun on Windows or Linux, too.

  • Is there an FTP client for Windows 7 with a text-based UI? (not text-prompt based, like ftp.exe)

    - by Alan B
    Is there such as thing as a text-mode FTP client for Windows 7 ? By 'text-mode' I mean one that runs in a CMD.EXE window as opposed to a Windows GUI application. It also needs to be something along the lines of FileZilla, i.e. menu-driven as opposed to command-entry clients like NcFTP or indeed the built-in one. edit: To avoid confusion, what I mean is an application similar to that pictured (ZTreeWin File Manager), which runs from CMD.EXE and uses text characters for its UI, within the CMD.EXE window. The built-in FTP client, and things like NcFTP offer a prompt at which you issue commands. That's not what I'm looking for.

  • Optimizing a memoization decorator not increase call stack

    - by Tyler Crompton
    I have a very, very basic memoization decorator that I need to optimize below: def memoize(function): memos = {} def wrapper(*args): try: return memos[args] except KeyError: pass result = function(*args) memos[args] = result return result return wrapper The goal is to make this so that it doesn't add on to the call stack. It actually doubles it right now. I realize that I can embed this on a function by function basis, but that is not desired as I would like a global solution for memoizing. Any ideas?

  • How to recursively move all files (including hidden) in a subfolder into a parent folder in *nix?

    - by deadprogrammer
    This is a bit of an embarrassing question, but I have to admit that this late in my career I still have questions about the mv command. I frequently have this problem: I need to move all files recursively up one level. Let's say I have folder foo, and a folder bar inside it. Bar has a mess of files and folders, including dot files and folders. How do I move everything in bar to the foo level? If foo is empty, I simply move bar one level above, delete foo and rename bar into foo. Part of the problem is that I can't figure out what mv's wildcard for "everything including dots" is. A part of this question is this - is there an in-depth discussion of the wildcards that cp and mv commands use somewhere (googling this only brings very basic tutorials).

  • Confluence not showing tips on wiki markup

    - by Guillaume
    After an upgrade, our confluence installation doesnt show the "Help Tips" on wiki markup (a box on the right side of the edit pane which give basic informations on wiki markup). If I view the source, I see that the div is there, but with a display:none attribute. This lead me to think that there is an option somewhere to activate or deactivate this, but I cant find it. Any idea ?

  • Cannot acess the new cloned server even after new IP address assignment

    - by tough
    I was able to clone a Ubuntu 10.04 server residing in Cloud. It appeared that I was not getting some IP for the new VM so I followed some of these: # cd /etc/udev/rules.d # cp 70-persistent-net.rules /root/ # rm 70-persistent-net.rules # reboot I didn't follow the later commands as I was unable to see two eth MACs as available in the referenced site. After this I am able to see some the IP for it, and is different form the original IP, I have added new IP to DNS server. Now when I try to access it with its assigned(new) domain it is directed to the old server. I can see both the VMs running with different IP. Where I might have gone wrong, I am new to this admin thing.
