• Have SkyDrive not sync some subfolders of "SkyDrive"

  - by Bram Vanroy

  I am working with SkyDrive for a while now and it is GREAT! The only downside is that I am syncing my laptop and my desktop and that they don't have the same files. Example: For recording, I have Cubase installed on my laptop. This programme creates a folder "Cubase LE" in "My Documents". "My Documents" is being sync'd. This means, that on my desktop a folder will appear, named "Cubase LE". But it is not needed there at all! So what I'm looking for is an option to disable some folders from being sync'd. Can this be done? Like, right-clicking on a folder and selecting an option "Don't sync with SkyDrive". Thanks.

• Equivalent of Windows 7 Winkey+Left / Winkey+Right for Window Tiling in OSX

  - by Koobz

  Windows 7 has a neat feature where the Windows Key in conjunction with the arrow keys tiles the active window. Windows key + left arrow moves it to the left half, windows key + right arrow moves your window to the right half of your monitor. Is there an equivalent to this functionality in OS X? Can anyone suggest some alternative metaphors by which to manage my windows? I find that OSX windows tend to be a bit more scatterbrained than their windows counterparts.

• Is there a small business router that shows bandwidth usage graphs in the admin panel?

  - by Robert Drake

  I support a large number of public libraries that are having their networks upgraded in response to a grant application. These libraries are generally home to between 6-15 computers and have little or no tech services either onsite or contracted remotely. In order to justify current and future purchases, a number of the libraries have requested routers that can provide bandwidth usage graphs that they can show to their managing boards. Is there a small business router that displays traffic graphs in the router administration web interface? The router needs to suppport DHCP and basic firewalling. No other features are required. Further, the reports just need to show overall trends. It is not necessary to show traffic by IP, by protocol/application, or by time of day. They just need an overall week to week, month to month, trend line. I'm familiar with MRTG/PRTG/tools that collect SNMP data from the router, but the libraries don't have the expertise for the configuration. I've considered installing the tomato firmware on some cheap home/home office routers, but if there's a commercial product that can be purchased that would be significantly simpler. Also the library boards would be much more likely to approve the purchase of a commercial product over a 'hacked' one. Any assistance would be appreciated.

• Finding out whether files are added, changed or deleted on a FTP server

  - by futureelite7

  I've recently been given the task to migrate about 200GB of data from one dedicated server to another. As this will take a week or more, I've been taking a snapshot of the current files on the FTP server using wget's mirror feature. However, since other users will probably be uploading / changing stuff in the meantime, the snapshot that I have made will not include the most recent changes. Since I only have access to FTP on this server, I'm planning to write a script that will recursively do a FTP stat on all files in the FTP folder, and compare the directory listing against the snapshot I have locally. If there are differences in the number of files, then I know files have been added or deleted. If the modification dates have been changed, then I know the files have been changed, and should redownload those files specifically. Am I missing anything in my approach, or are there any possible improvements to this approach?

• Need a good mp3/internet radio organization system...

  - by Zombies

  So I feel that winamp alone doesn't work well for me. I have this one playlist that all kinds of stuff gets crammed into. I need a system (this can easily be 1 program or several): Need to be able to... play mp3's from my library (just a directory structure with mp3's). Save radio station's, and easily remove/add new stations play random mp3's which are not part of my library and will probably be deleted in the future, yet won't clutter my library index!

• How to update grub with puppet?

  - by Tombart

  I would like to change a line in /etc/default/grub with puppet to this: GRUB_CMDLINE_LINUX="cgroup_enable=memory" I've tried to used augeas which seems to do this magic: exec { "update_grub": command => "update-grub", refreshonly => true, } augeas { "grub-serial": context => "/files/etc/default/grub", changes => [ "set /files/etc/default/grub/GRUB_CMDLINE_LINUX[last()] cgroup_enable=memory", ], notify => Exec['update_grub'], } It seems to work, but the result string is not in quotes and also I want to make sure that any other values will be separated by space. GRUB_CMDLINE_LINUX=cgroup_enable=memory Is there some mechanism how to append values and escape the whole thing? GRUB_CMDLINE_LINUX="quiet splash cgroup_enable=memory"

• DPMS, keep screen off when lid shut

  - by Evan Teran

  I have a laptop running linux. In my xorg configuration, I have DPMS setup so that the screen automatically turns off during several events. In addition to that I have to the following script tied to ACPI lid open/close events: #!/bin/sh for i in $(pidof X); do CMD=$(ps --no-heading $i) XAUTH="$(echo $CMD | sed -n 's/.*-auth \(.*\)/\1/p')" DISPLAY="$(echo $CMD | sed -n 's/.* \(:[0-9]\) .*/\1/p')" # turn the display off or back on export XAUTHORITY=$XAUTH /usr/bin/xset -display $DISPLAY dpms force $1 done Basically, this script takes one parameter ("on" or "off") then iterates through all of my running X sessions and either turns on or turns off the monitor. Here's my issue. When I close the lid of the laptop, the screen goes off as expected, but if a mouse event occurs (like if something bumps into the table...) then the screen turns back on even though it is closed (I can see the light through the side of the laptop). Is there a way to prevent the screen from turning on during a mouse event if the lid is closed?

• gvim Cannot make changes, 'modifiable' is off issues with file explorer.

  - by nos

  In gvim using netrw(the file explorer), I usually middle click a file to open it in the last active window. This just leads to an error stating "Cannot make changes, 'modifiable' is off". Another middle click, and the file opens fine where I expect it to. All buffers are saved, there's no uncommuted changes anywhere. What causes this, and what can I do about it ? Here's a pic when I middle click a file:

• ghc6 install trouble: hGetContents: invalid argument (invalid UTF-8 byte sequence)

  - by olimay

  Having trouble installing ghc6 on Ubuntu Maverick via apt. Here's what seems to be the relevant error that comes up when I try to (apt-get|aptitude) install ghc6: A package failed to install. Trying to recover: Setting up ghc6 (6.12.1-13ubuntu1) ... ghc-pkg: /home/opm/.ghc/i386-linux-6.12.1/package.conf.d/unix-compat-0.2-edefa7bced91ebe610d455bab466e200.conf: hGetContents: invalid argument (invalid UTF-8 byte sequence) (Here's the full output, if you're interested: http://paste.ubuntu.com/566475/ ) This still happens after apt-get clean and apt-get update. My searching around has not really helped me understand what's going on, except that it might be caused by a mismatch in locale. So, here's the output of locale too: LANG=en_US.utf8 LANGUAGE=en_US:en LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" LC_COLLATE="en_US.utf8" LC_MONETARY="en_US.utf8" LC_MESSAGES="en_US.utf8" LC_PAPER="en_US.utf8" LC_NAME="en_US.utf8" LC_ADDRESS="en_US.utf8" LC_TELEPHONE="en_US.utf8" LC_MEASUREMENT="en_US.utf8" LC_IDENTIFICATION="en_US.utf8" LC_ALL= Any ideas? Additional background: this all seems very strange to me, because I used to have ghc6 installed correctly--I use XMonad as my main window manager most of the time. I tried to install haskell-platform (through apt), which failed and told me that there was something wrong with ghc6, and so I reinstalled ghc6 and began to get the above error message.

• User for MSSQL 2008 Service Accounts

  - by Campo

  I want to create a Domain User that runs the SQL Service Accounts. The reason for this is that I have setup mirroring and MS recommends having the same user (a domain user account) running the services across all the the computers in the configuration to ensure mirroring will work properly. Right now in the test environment I just had them run under my user for simplicity. But now that I know what I am doing I would like to test the configuration more accurately. I am also aware that it makes things much simpler if this user is an administrator. My question is. Should I just create a simple user SQLSERVICEUSER and make it an administrator? Seems a little insecure to me. Anyone have a more elegant solution?

• Windows 7 Goes to Sleep in conflict with Power Option Setting

  - by Decker

  My Del Dimension E521 running Windows 7 puts itself in sleep mode each night -- despite the fact that I have chosen a power option that specifies NEVER Each morning I find the monitor blank and I have to hit the power button on the PC at which point Windows "resumes". The system event log shows this: Source: Microsoft-Windows-Kernel-Power Date: 3/27/2010 3:21:10 AM Description: The system is entering sleep. Sleep Reason: System Idle My specific power options are: Turn off Display : 20 Minutes Put the computer to sleep : Never Is there some other setting coming into play here?

• Best way to find the computer a user last logged on from?

  - by Garrett

  I am hoping that somewhere in Active Directory the "last logged on from [computer]" is written/stored, or there is a log I can parse out? The purpose of wanting to know the last PC logged on from is for offering remote support over the network - our users move around pretty infrequently, but I'd like to know that whatever I'm consulting was updating that morning (when they logged in, presumably) at minimum. I'm also considering login scripts that write the user and computer names to a known location I can reference, but some of our users don't like to logout for 15 days at a time. If there is an elegant solution that uses login scripts, definitely mention it - but if it happens to work for merely unlocking the station, that would be even better!

• samba sync password with unix password on debian wheezy

  - by Oz123

  I installed samba on my server and I am trying to write a script to spare me the two steps to add user, e.g.: adduser username smbpasswd -a username My smb.conf states: # This boolean parameter controls whether Samba attempts to sync the Unix # password with the SMB password when the encrypted SMB password in the # passdb is changed. unix password sync = yes Further reading brought me to pdbedit man page which states: -a This option is used to add a user into the database. This com- mand needs a user name specified with the -u switch. When adding a new user, pdbedit will also ask for the password to be used. Example: pdbedit -a -u sorce new password: retype new password Note pdbedit does not call the unix password syncronisation script if unix password sync has been set. It only updates the data in the Samba user database. If you wish to add a user and synchronise the password that im- mediately, use smbpasswd’s -a option. So... now I decided to try adding a user with smbpasswd: 1st try, unix user still does not exist: root@raspberrypi:/home/pi# smbpasswd -a newuser New SMB password: Retype new SMB password: Failed to add entry for user newuser. 2nd try, unix user exists: root@raspberrypi:/home/pi# useradd mag root@raspberrypi:/home/pi# smbpasswd -a mag New SMB password: Retype new SMB password: Added user mag. # switch to user pi, and try to switch to mag root@raspberrypi:/home/pi# su pi pi@raspberrypi ~ $ su mag Password: su: Authentication failure So, now I am asking myself: how do I make samba passwords sync with unix passwords? where are samba passwords stored? Can someone help enlighten me?

• What is the best package repository for Debian ?

  - by Dan Sosedoff

  Hello everybody I have a question regarding packages repository in Debian (Lenny). A new server at rackspace cloud service comes with nothing (plain system) so i had to upgrade system and install all necessary packages by myself. But the problem is that default repositories does not provide newer versions of software i need (PHP is 5.2.6, comparing to 5.2.13). In CentOS i used to get all new packages from third-party sources, which works really well till now. I have talked to guys from rackspace about it and looks like they cant provide anything except kernel headers. And i dont really want to build from source. So, whats the way to get newer software ? Any good third party sources? Thanks.

• How have you saved green by going green?

  - by Bob

  For the purpose of this question, I am interested in server/datacenter related hardware. Have you had any measureable amount of ROI by swapping existing hardware to more "green" or energy efficient hardware? For example, VMWare says you can reduce energy consumption by up to 80% by using virtualization. I have also heard of a cooling solution from HP which is suppose to reduce a small amount of engery usage (<25% I think). Google has also done something by integrating a UPS into their power supplies to reduce energy consumption. Any real world experiences would be great, but if you have any details on initial cost, savings and pay off time about what changes were make that would fantastic. I am not only interested in virtualization, I am interested in anything.

• How tot track which program causes my harddrive to spin up

  - by Andreas

  I have a strange problem: Every half hour one of my hard disks gets powered on again. I recognize this by the sound of a hard disk spinning up. So far I was not able to track which program could cause this. I ran Process Monitor to see whether there is an I/O peak coinciding with the spin-up. I checked Windows event viewer if there is an appropriate event at the same time Any ideas other than the usual disabling-services/programs etc. (which would be my next investigation step)? Also, it would be helpful to have a program that shows the current power status of all my drives, if there is one. Harddisk Sentinel unfortunately cannot do the job because it powers on all drives upon start and prevents their going into sleep mode. Thanks in advance. :)

• Using Xbox 360 controller with Mac OS X (specifically turning it off)

  - by Bob King

  So I've been using this driver for a few months with the Xbox 360 Wireless Controller For Windows with my Mac Mini. Here's an article about the driver on Gizmodo. The driver works really well for actually using the controller, but there doesn't seem to be a way to power off the controller without pulling the batteries. Does anyone know of a replacement driver that includes power-off capabilities, or know of some other undocumented way to turn the controller off? Note: I've been having problems getting to the site, but it could be our corporate filtering.

• Error removing packages in Ubuntu using Synaptic

  - by ronakin

  I'm using Ubuntu 10.04 and during my tries to free space I've removed several packages such as: openoffice, all editors, and some more packages such as players and printers drivers that I don't need and seem o.k to remove. However, after restart, the graphical interface doesn't load, I'm in the xserver, I have console but not gui. I was wondering if anyone can tell me which packages I should not remove or let me know of dependencies I need to consider when messing with packages? Thanks!
