• How do I reattach to Ubuntu Server's 'do-release-upgrade' process?

  - by Alex Leach

  I accidentally pressed Ctrl+C during Ubuntu Server's do-release-upgrade process. I'd dropped to a shell to compare a .conf file in /etc/. When I pressed Ctrl-C, it asked whether I wanted to try to reattach to the upgrade process, but it failed to do so. So I quit, and now there's a hanging dpkg process which is holding onto the apt lock. This is a virtualised server with no GUI frontend... Is it possible to recover the upgrade process, or do I have to kill the dpkg process and start again? UPDATE:- AFAICT, there was no way to reattach to the upgrade process. However, it wasn't a disaster at all. I killed the hanging dpkg process, and then ran dpkg --configure -a. This walks you through reconfiguring all packages already installed on the system, tidying up any problems whilst it does so. After that, I used aptitude to upgrade the remaining packages, which had already been downloaded, but hadn't been installed or configured.

• Datamapper In Memory Database

  - by Daniel Ribeiro

  It is easy to setup Datamapper with a Sqlite3 in memory database with: DataMapper.setup :default, 'sqlite3::memory:'. However, when testing, I'd like to destroy the whole in memory database after each test, instead of invoking automigrate! as a shortcut on dropping everything. Is it possible? Or is it enough to set the default repository to nil, and let the garbage collector dispose of it?

• How can I launch RemoteApp on Windows Server from server itself at startup

  - by Rusted

  I have Windows Server 2008 R2 with RDS and custom desktop (GUI) application installed on the server. The app is started as RemoteApp on server by user from his desktop computer (or, sometimes, he can work from notebook over VPN). Some details about environment: the server automatically shuts down every evening and automatically power-on every morning (this is a requirement) desktop application do some precalculations/precaching on startup and it can take lot of time mentioned application have some memory leaks, so I can't use hibernate instead of shutdown When user launching this app from his computer, he can't start work with it until this app finishes pre-initialization. Is there any way to start RemoteApp session at the server startup (without actual user logon), so that the user could connect to this session from his computer later? I don't want to involve the user's computer to make it work. I have tried to do it by Windows startup script, but have no luck - starting RDP session requires actual user session.

• ubuntu12.04 hangs at checking battery state

  - by crystalbass17

  My 12.04 system hangs at "Checking battery state". At this stage, no commands work eg: ctrl+alt+f1, alt+f5. I ran recovery mode, I ran the command sudo mount -o remount, rw sudo dpkg-reconfigure gdm and gdm was the only one installed so I didn't get a GUI screen. I have an integrated graphics card "Intel Corporation Mobile 4 chipset Integrated Graphics Controller (rev 07)". So I cannot install nvidia drivers as everyone else suggests. I have gone through several similar questions but everyone suggests reconfiguring gdm or reinstalling graphic drivers. I did sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get upgrade to get the latest x-swat drivers. The system still hung at the same line. The other option is to reinstall ubuntu, which is out of the question, since we have a very specific install for our project where the settings are very hard to duplicate. Suggestions/Comments welcome.

• How to make sure rsync sets proper file permissions?

  - by BetaRide

  I'm transfering data from a synology box to a debian box with rsync. Unfortunately the permissions of all transfered files are set to rwxrwxrwx on the debian box. I want to make sure this files can be seen by the owning user only. Is there a way to tell the debian box to set the permissions to something like rwx------? The rsync job is set-up through the DSM GUI. If possible I'd rather avoid hacking the synology box and do something on the command line. This means I'm looking for a way to set the permissions on the server side (debian box). I'm using the latest DSM version (4.1).

• IRC "proxy" for persistent connection between several computers

  - by Zeta Two

  I'm looking for a program that enables me to stay connected to one or more IRC networks and be able to view the log even though I connect from several different computers. I'm thinking about something like a proxy running on a server who always is connected to the servers/channels I want and to which I connect from whichever client I want to use. Does anyone know of a program like this? Edit: Apparently I could be running a IRC session in a shell on a server and connect to this but I would like something more GUI:ish.

• sql server log shipping

  - by voam

  I am setting up log shipping with two 2008 sql servers connecting with a vpn. As far as I know as long as the sql agent is able to access the share on the primary/secondary servers everything will work. When I set up the Log shipping on the primary server using SQL Mangagement Studio, before I can set any of the "Secondary Database Settings" it asks me to connect to the secondary server. But I really don't want to open up the connection to the secondary server. I will be initialing this secondary database with a backup so as long as the transaction logs get copies everything should work. How to I work around the GUI not enabling any of the settings for the secondary server until I actually connect to it? Thanks in advance!

• How can I load an image directly into the Windows clipboard from the command line?

  - by Daniel J. Pritchett

  My dad asked me how he could script the pasting/inclusion of images in various applications. I'm sure I could script out some quick <img src=... HTML but I believe he's also looking to do this in Windows GUI applications like Word or Outlook. So, how could I script a process with the following inputs and outputs: load_image_into_clipboard_script.cmd sample_file.jpg Clipboard now contains the aforementioned image file, just as if I'd e.g. opened it in Paint and done a Select All - Copy. I noticed there's a clip.exe utility with Vista/Win2003 and up; perhaps that will be a useful intermediary?

• Best way to replicate servers

  - by Matthew

  I currently have two servers both with linux software RAID1 configurations. They use heartbeat and DRBD to create a shared DRBD device that hosts a a exported NFS directory. The servers run Ubuntu Server with a LXDE GUI and some IP These servers are going to be placed on fishing vessels to act has redundant storage for IP cameras. My boss wants me to figure out the most efficient way to create these servers. We might be looking at pushing out several systems a week. Each configuration will be almost identical besides IP addressing. What would be the best method to automate the configuration process? We are trying to cut down on labor costs to set these up. Imaging and Proceeding are both on my mind right now

• Where to find free-to-use, complex test databases?

  - by Jay

  I need a database for testing a data masking solution. Any database would do (Oracle/MSSQL flavor). I just need the schema / db definition. I have tools to generate data records. The magnitude of database I am looking should have 30 odd tables with 30 odd columns in each table - a HUGE database. Do freely available complex database /schema definitions exist on the internet? If yes, where do I find them?

  Hi, I'm looking for a package (any language, really) that I can use on a corpus of 50 documents to perform interdocument similarity testing in various metrics, like tfidf, okapi, language models, lsa, etc. I want as a result a document similarity matrix, i.e. doc1 is x% similar to doc2, etc... This is for research purposes, not for production. I specifically want the doc similarity matrix as I want to correlate this with human ratings. Thank you in advance!

• ubuntu pptp connections from command line

  - by Ian R

  I'm using a lot of vpn connections daily for my work and I want to program a pptp dialer in python to ease my job a little bit by automating things. I usually go with network-manager-pptp to setup my connections but I would like to skip this gui tool and do it from the script. Something like a dialer. My question is. Can pptp connections be established using the command tools only? Also, where does network-manager-pptp saves its failes so I can take a look and see what configs it generates. Any help is much appreciated.

• RIA: Manipulate DOM

  - by stephanos

  I want to display a website embedded in my own site and modify the DOM (e.g. change a button's color/size), similar to what Firebug is capable of. I'm aware of the security issues that arise - my plan is to use this approach to do live website usability testing (A/B style). I'm not limited to any specific RIA framework (yet would prefer Flex) - but it has to work without installing anything (so no AIR). Cheers :-)

• How can I figure out exactly which process is keeping my Mac from going to sleep and waking it up?

  - by pattern86

  I have read this knowledgebase article, but would like to know if there's a way to tell exactly which process is causing my Mac not to follow the sleep schedule I have set in System Preferences Energy Saver. I have narrowed it down to a being a process and will explain why I think so (see below). I am running OS X (10.6.5) on the new iMac 27" and I am certain it's not the following: The "Wake for Network Access" checkbox in Energy Saver settings (has never been a previous issue) Peripherals (has never been a previous issue) Any active GUI application (all are closed) Additional USB/FireWire drives (none are connected) Bluetooth (it's off) Sharing services (has never been a previous issue) The symptoms are as follows: The computer doesn't go to sleep at the predetermined time. It will wake up some number of hours after being put manually to sleep (but not within the first few seconds/minutes.) Is there a specific string I should be looking for in Console? I have tried searching for "wake" and "sleep" but can't make total sense of the results.

• Objective-C Using Accelerometer (iPhone)

  - by Johannes Jensen

  I have a class called MainGame, which is defined like this in my .h: @interface MainGame : Renderer <UIAccelerometerDelegate> Then later in my .m I have this: - (void) accelerometer: (UIAccelerometer *)accelerometer didAccelerate: (UIAcceleration *)acceleration { // here I would read values like accelerometer.x NSLog(@"accelerated!!1"); } Am I doing it right? Currently I'm only testing in iPhone simulator, I'm going to buy the apple $99 developer thing soon. It doesn't log "accelerated!!1", but I'm guessing that's because I'm not running it on an actual device yet?
