• Dye Sub printer with specific prints remaining - can I command-line query this?

  - by Jason N

  Hey, I've got a Sony Dye-Sub printer that holds ink/paper sets - i.e. a very certain amount of ink and paper for ~200 prints. This information is available to me from within Control Panel Printers Preferences Printer Device Information (i.e. current 189 remaining prints). Any way I can perhaps get this information from the command line? I'd like to write a little program to tell me when the number of prints gets low (i.e. < 20), rather than suffer the annoying Windows "run out of paper" popup. I've found the Windows VBScript print utilities, but can't seem to find the request I need for this. Any suggestions? Jason

• How to use my computer to control a lamp?

  - by nona urbiz

  I've been researching computer automation systems, but everything I've found has been overkill for what I'm interested in. Can anyone help me control a lamp that is on my desk, plugged in the wall beneath the desk, with my computer (also on the desk, usually). What got me thinking is that I have the lamp plugged into a Belkin extension cord/surge protector that came with a wireless switch that toggles the power going to 6 of the eight sockets. Can I somehow hook my computer into this? I'm not too afraid to get into some wiring type thing, but do have a somewhat limited budget. It'd also be cool to get a dimmer in the loop too. thanks aha. after more research, i have realized what i'm looking for is instructions for a DIY version of this that won't look so ugly, and that i can build a UI for rather than shortcuts.

• Windows 2000 under Windows 7 Virtual PC not working correctly

  - by dave

  I have just moved my Windows 2000 Virtual PCs from Vista to Windows 7 Professional (64-bit). The machines work to a point but I have found some problems: drive mapping does not seem to work any more. I need this to exchange data. I do not need network access to the virtual PC so would rather leave it unconnected. the virtual PC would automatically shutdown the session and go to the login screen after a few minutes of inactivity. I tried installing the Virtual PC Integration Components but the install failed (one of the messages basically says it's XP+ only). Now I'm stuck in 640x480 mode with mouse capture. I have heard that you can install an older version of the Integration Components but this sounds a bit suspect. Does anyone have any ideas on how to get Windows2000 working with drive sharing on a Virtual PC?

• Identify SATA hard drive

  - by Rob Nicholson

  Very similar question to: Physically Identify the failed hard drive But for Windows 2003 this time. Scenario: Four identical SATA hard drives plugged into motherboard (no RAID controller here) Configured as single drive in Windows as a spanned volume One of them is starting to fail with error "The driver detected a controller error on \Device\Harddisk3" How do you cross-reference Harddisk3 to the physical SATA connection on the motherboard so you know which drive to replace? I know replacing this drive will trash the spanned array requiring it to be rebuilt anyway so my rough and ready solution is: Delete the spanned partition Create individual partitions on each drive labelled E: F: G: and H: and work out which one is Harddisk3 Power down, remove each disk one at a time, power-up until the drive letter disappears But this seems a rather crude method of identifying the drive. The SATA connectors will be numbered on the motherboard but I appreciate this might not cross-match to what Windows calls them. Thanks, Rob.

• What's the difference between sudo su - postgres and sudo -u postgres?

  - by Craig Ringer

  PostgreSQL users peer authentication on unix sockets by default, where the unix user must be the same as the PostgreSQL user. So people frequently use su or sudo to become the postgres superuser. I often see people using constructs like: sudo su - postgres rather than sudo -u postgres -i and I'm wondering why. Similarly, I've seen: sudo su - postgres -c psql instead of sudo -u postgres psql Without the leading sudo the su versions would make some sense if you were on an old platform without sudo. But why on a less than prehisoric UNIX or Linux would you use sudo su ?

• Renting an "EC2" server VS buying one (for a start up in initial stages)

  - by krish p

  We are a small start up in the early stages and are working on a SaaS-based Rails product. Currently, we use EC2 for a small instance and have a need for another large/extra-large instance as we are beginning to deploy to the Cloud and get ready to release our "alpha" version. While EC2 was my choice for numerous reasons (reliability, accessibility - small team is geographically dispersed, maintainability, and things of that nature), it appears to be rather expensive. While the product will ultimately be deployed in the Cloud (be it EC2 or otherwise) and that experience would help the development team, would it make sense to purchase a physical server and stick it in the basement or bite the bullet and pay the price for EC2 (or other Cloud Providers)? While such decisions are driven by numerous factors, it would certainly help to get the thoughts of other folks who may have been in similar situations. Hence, the post. Thanks much!

• 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).

• Compiz shutdown hook?

  - by ???

  I want to check 10+ local Git repositories if they have any unpushed commit, before shutdown. (I always forgot to push them, so later, the next morning I came office and back home again) I think maybe the shutdown process can check some conditions to meet, if any condition is not met, then give the user the choice to continue to shutdown or just cancel. Then, I can write something to hook the shutdown to check my Git repository to push. EDIT I have changed the title from Ubuntu shutdown hook to Compiz shutdown hook. I want to hook to the small lovely shutdown button, rather then click another ugly shortcut icon on the desktop.

• How do you sync photos with your family?

  - by romkyns

  We've always been trying to share photos within our family, despite all living in different countries. This has been very challenging. We have about 50GB of photos that we share with each other. Everyone organizes them differently, so rsync/Syncplicity don't work. Everyone likes their photos on the fast hard drive rather than a slow website with reduced quality, so online sharing websites are a no-go. So far we have been essentially syncing them manually, via a shared folder that new photos are placed to and collected from. This is laborious and prone to errors, that usually leave one of us without all the photos without even knowing. To those who are in a similar situation, how do you solve this?

• Forward emails from specific domain in Exchange

  - by neildeadman

  Our Exchange server handles emails for @ourdomain.com (for example). We have multiple clients that will send emails to our [email protected] email address and we want to configure server-side rules that will forward emails from each client's domain to a different email address within our exchange server. For example: [email protected] sends an email to [email protected] and we forward it to [email protected] [email protected] sends an email to [email protected] and we forward it to [email protected] ...and so on. It would be nice if we can additionally stop the email arriving in the [email protected] mailbox, but that is not a specific requirement. We have a rule setup in Outlook that sort of works, but it doesn't do all from a domain only specific email addresses. It does work when Outlook is not running which is a start. I realise it would be easier to give each client a partiuclar email address and have them email straight to that rather than all use the same, but this is what I have been asked to setup.... :S

• Can GoogleApps exist with Exchange 2003

  - by Adam M.

  I am looking at the next step in our Groupware solutions. Rather got with a conventional add a new MS Server/MS Exchange to allow for growth and expanding offices. Could an Office operate with both an existing Exchange server setup and migrate a portion of mailboxes to the GoogleApps platform? I want to see if the we could use the GoogleApps for managers and larger mailboxes, and leave a large amount of small mailboxes on the existing hardware that is configured for Exchange/outlook? Can the two co-exist in an longterm configuration, where they can 'play nice' together? Is there any options that would allow for for this and would this have limitations? Such as the Free/busy connectors (Calendaring)? Is there any pitfalls for this type of design? Thanks

• How to rename database without first stopping SQL instance to flush connections

  - by John Galt

  Is there a way to force a database into single user mode so a script can be run to rename databases? I find I have to Restart the instance of SQL (to force off any connections from a web app, etc.) and then I can run this script: USE master go sp_dboption MDS, "single user", true go sp_dboption StagingMDS, "single user", true go sp_renamedb MDS, LastMonthMDS go sp_renamedb StagingMDS, MDS go sp_dboption LastMonthMDS, "single user", false go sp_dboption MDS, "single user", false go After this script runs, I can restart IIS for my web app and it can connect to the new production database. All the above works well and we've been doing this for years but now we've upgraded to SQL 2008 and the SQL2008 instance also hosts other databases that support other web apps. So, rather than using a Restart of the whole SQL instance to enable subsequent single-user mode on 2 databases, is there a less intrusive way of accomplishing this? Thanks.

• Using Gentoo's `ebegin`, `eend` etc under Ubuntu

  - by Marcus Downing

  We're quite fond of the style of the ebegin, eend, eerror, eindent etc commands used by Portage and other tools on Gentoo. The green-yellow-red bullets and standard layout make for very quick spotting of errors, on what would otherwise be very grey command line output. #!/bin/sh source /etc/init.d/functions.sh ebegin "Copying data" rsync .... eend $? Producing output similar to: * Copying data... [ OK ] As a result we're using these commands in some of our common shell scripts, which is a problem for the people using Ubuntu and other linuxes. (linuces? linuxen? linucae? other distros) On Gentoo these functions are provided by OpenRC, and imported with functions.sh file (whose exact position seems to vary slightly). But is there a simple way of getting these commands on Ubuntu? In theory we could replace them all with dull echos, but we'd rather not?

• VirtualBox, physical disks, and snapshots

  - by noamtm

  I have an Ubuntu guest installed on a raw HDD (entire disk, not a partition). It runs just fine under WinXP. In addition, I was able to boot directly into it (using the BIOS boot-device selector). At some point, I have created a snapshot of the VM. I have made some changes since then. Today, after a long time, I tried booting into the "VM" disk. It worked, but all the data there is pre-snapshot (or, rather, frozen at the snapshot). Can I somehow merge the changes since I took the snapshot into the physical state?

• Windows Media Center command line options?

  - by Pridkett

  Is there a command line interface to Windows Media Center in Windows 7. I have an SSH daemon installed on my media center box and would love to be able log in via SSH and get the list of upcoming recordings. As it is, I need to use Remote Desktop and then tell Media Center to run in GDI mode to display the upcoming recordings which is slow and cumbersome. Here are interesting commands that I'm wondering about: List upcoming recordings List most recent recordings Status of scheduler I'd rather not have to install Remote Potato to accomplish this.

• Software to draw custom street maps?

  - by jay

  I'm looking for any (Windows) software that allows me to draw custom street maps. I'm not looking for something that displays existing maps from real places, but something that allows me to define my own map. Obviously this can be achieved through any graphics program however I am wondering if there's a software which makes it almost drag-drop easy to create your own maps of visual quality to that of Open Street Maps, Google Maps, street directories etc. Preferably an offline desktop app with attention on design rather than complex geospacial specifics. Context: I want to make a detailed street map for a game I'm making.

• firefox addons and their silly news tabs

  - by jettero

  Something like 30% of the addons I have in firefox update every other week and feel the need to pop open a tab about how awesome they are and all the cool things they changed. I just don't care at all and I'm very annoyed by these news tabs. When firefox opens, I want to see my home page. I've been looking for an addon to disable or kill them before I even have to look at them. Rather like addblock-for-addons. Short of finding a plugin that disables them, I'm seeking information about common interfaces so I can try to figure it out on my own. I'm wondering if I could do it in greasemonkey somehow. For example, is there something common about the url for the tabs?

• Virtual Machine files on ramdisk doesn't run faster than on physical disk

  - by Landy

  I installed total 36G memory (4x8G + 2x2G) in the host (Windows 7) and I used ImDisk to create a 32G ramdisk and format it to NTFS file system. Then I copied the virtual machine (in VMware Workstation format) folder, including vmx, vmdk, etc... to the new created ram disk. Then I tried to power on it in VMware Workstation. What made me surprised is that the performance is not better than before. It cost almost the same time to power on the Windows 7 VM. I check the Resource Monitor in the Windows 7 host, and the statistics of CPU, disk, network are rather normal. The memory has reported 3000+ hard fault/sec when guest OS boot then drop to 0 after the guest powered on. Any idea about this issue? I had thought the performance of ramdisk will be better than physical disk in this case. Am I wrong? Thanks.

• How to open recovered files in word?

  - by GiH

  My computer restarted while I was asleep because of system updates (need to turn that off), and when I opened up Word the first time after it restarted, it gave me a pane on the left hand side that showed me all the documents I had opened. I chose one of the documents but I want to open them all, how can I bring that pane back? Update: I forgot to mention I'm on Word 2007. I've found that if you go to C:\Users*YOURUSER*\AppData\Roaming\Microsoft\Word you can see the autorecovery files. Mine are still in there, but I don't want to touch them, I'd rather bring back that pane and do it right just in case they disappear as soon as I double click haha...

• Is there no such thing as a Gigabit switch?

  - by Torben Gundtofte-Bruun

  According to the manufacturer specification, even my rather plain desktop computer has "Gigabit Ethernet". So when I want to copy large files over the LAN (not Internet) it would make sense to have a gigabit switch. I'm searching eBay for a gigabit switch for a planned home network upgrade. The products I find are all labeled "gigabit" but they all have 24 x 10/100Mbit autosensing ports and sometimes 2 x 10/100/1000Mbit autosensing ports. It was my understanding that 10/100 is ancient and that modern computers have network interfaces that work with 1000Mbit, so it would make sense to get a switch that has 24 x 1000Mbit ports. Did I misunderstand, or are sellers (deliberately?) mislabeling older hardware? (Let's not dive into wired vs. wireless networks and how "N" wireless is fast. You'd be right, but not answering the question.)

• Windows 8 Automatic Logon Tick Box Missing

  - by Luke Kenny

  Recently (in the past few days,) perhaps following the latest Windows Update, it appears the tick box to allow automatic logon in "control userpasswords2" or "netplwiz" has disappeared. I have two machines running Windows 8 and the option is no longer available for either. Both machines user a Microsoft account, rather than a local account, for the primary user to logon. The only other recent change I can think of, and I am confident this change was made well before this issue arose, was enabling HomeGroup. How can I re-enable automatic logon for the affected user?

• CentOS 6 - YUM Local Repo - Ensure consistent package distribution

  - by Mike Purcell

  I've read a few guides outlining how to setup a local YUM repo, but none of them explicitly stated an answer to my question; If I set up a local YUM repo, does that mean that any CentOS servers which pull from said repo will never be "ahead" of the local YUM repo? I want to ensure a consistent package distribution across all my servers. Right now, when I do a yum update, even on a daily basis, the servers can be out of alignment. For example if I run YUM update on my dev server in the morning, then run YUM update on one of my production servers in the afternoon, the production server may have picked up a new version of a package that the dev server did not pick up, due to the time window between the update commands. Rather, I'd prefer that I run yum update from my dev server which has access to remote upstream yum repos, then let it sit for 2 weeks, after which I run yum update on my production servers against the local repo on my dev server.

• Grant relay to servers based on AD security group membership

  - by john

  We're moving our relay from an Exchange 2003 server to an Exchange 2010 server. I was hoping the "Grant or deny relay permissions to specific users or groups" option would still be available in some form, but I can't find out how to do it. I've read up on recieve connectors and so far I can't get it to work. I have edited the security on the Recieve Connector to allow the following extended rights to the group and added computer accounts to that group: Accept Routing Headers Bypass Anti-spam Submit to Server Accept any Sender Accept any Recipient Then I suddenly realised while testing... How would the receive connector resolve the permission to a particular AD object, maybe a reverse DNS lookup? What I'd like to know is if what I'm trying to achieve is possible, and how it would be possible. I would rather not revert to an IP-based list as this is not as manageable, and I'm trying to avoid creating static IPs/reservations for a number of workstations that would otherwise not need them.

• Is there a way to customise PPD distribution of printer drivers effectively with Mac Os X server?

  - by glenstorey

  Hi, we have two network printers shared via our 10.5.8 Mac Os Server machine. They have drivers provided by the manufacturer that allow job logging (printing with a print code). I've installed said drivers on the server, but when we distribute the printer on our Mac Os clients (using add printer via bonjour) it deploys older drivers that don't support Job Logging. Is there a way to update the store of print drivers (cups drivers?) on the server so it distributes the updated drivers, rather than the older one?

• Horde on Debian: packages or upstream?

  - by fhd

  I'm currently using the Horde projects IMP, DIMP, MIMP, Ingo, Kronolith, Mnemo, Nag, Turba and Sork. I ignored the (rather outdated) Debian packages and installed the upstream versions. A few years later, my Horde installation is a bit outdated and I consider updating each project and each version individually a pain. The Debian stable packages are as outdated as ever, but squeeze will deliver reasonably current versions, so I'm considering switching to the Debian packages as soon as squeeze is released. What would you recommend for software packages like Horde? Using the upstream versions and manually updating or using the distribution's packages?
