• Turn Windows 7 desktop into grayscale

  - by Axarydax

  Is there a universal way to turn Windows 7 Aero desktop, all windows, etc into grayscale? I had an option to do this in Intel video drivers on my old laptop, now I have NVIDIA and don't know how to replicate this effect. There might be a shader or filter that would cause Aero to render stuff into grayscale, but I was unable to find anything. Or must it be explicitly supported by video driver as a bonus?

• What is the simplest batch scheduler to set up on a small linux cluster?

  - by Peltier

  We have about 10 heterogeneous machines we would like to run various jobs on. The current situation is that people log in on a machine with ssh, see if other people are running stuff on it, then use screen to run the job. I'd like to automate this process, but I don't have enough time to install a full-fledged cluster solution. So what's the simplest thing I can do?

• Unable to delete Gmail profile in Outlook 2010

  - by Michele

  I used to have 2 Gmail profiles set up in Outlook 2010. I initially had it set up using IMAP, but I deleted it (or so I thought), and re-set it up the old-fashioned way without IMAP. Then finally, I deleted the 2nd Gmail profile altogether. So now I only have ONE Gmail profile set up in Outlook 2010 and it works fine. The problem is that the original Gmail IMAP folder for the 2nd Gmail account is still in my list of folders when I use Outlook. I've already disabled IMAP via my Google Gmail account. But I am unable to delete the folder from Outlook 2010. I have checked in the account settings and it is NOT in my list of email profiles or the data files. Has anyone else had this problem?

• What are the IPv6 Public and Private and Reserved ranges

  - by vipin raj

  I just want to know what are all the public IPv6 ranges which ISPs or other users can use? Also need a list of addresses which can be used in private networks and also the list of addresses which never can be used in any network. I have been searching through different web sites. But none gives a reliable answer. Actually we are developing an application which allows user to plan their IP address(create supernets, subnets, hosts, assign host to ports etc). So my application should be able to distinguish between all kinds of address ranges, whether it is reserved, public, private, multicast etc

• Fixing/Extending Standard Windows File Open/Save Dialog [closed]

  - by scunliffe

  Possible Duplicate: Change left side link of the Save As Dialog for a DropBox one? Almost every time I use the standard Windows (XP) File Open/Save Dialog I get frustrated in how long it takes me to navigate to where I want to go. :-( (I won't even get into the MS Office dialog that makes things even worse) This is the dialog I'm referring to (with some notes) Notes: Wouldn't a Drive list be handy in here? C:\, D:\, E:\, etc. What about a breadcrumb URI? (the magenta list of links) Why isn't Program Files one of the icons on the left? (green) I'm always going in there for something Why can't I type "../../../" to navigate up multiple directories in the File name box? (blue) There has got to be some utilities out there that can "hijack" or "overwrite" this core windows dialog to provide a much better set of options. I'm looking for any/all solutions to help fix this dialog.

• bigbluebutton or openmeetings?

  - by Adam Monsen

  I want to set up a server for small group meetings. I'm looking for features like audio conferencing, multi-point video, screen sharing... stuff like that. I'm familiar/comfortable administering Ubuntu servers, so for this task I'd likely fire up a small EC2 server running Ubuntu. I'm most interested in using FLOSS. I see there are at least a couple of options out there. For example: bigbluebutton and openmeetings. Anyone installed either (or a different one) and have recommendations/tips? If yes, have you ever upgraded same? I notice bigbluebutton has deb packages, so that might be pretty straightforward. openmeetings appears to support logging in with a facebook account; that might be a good way to avoid having to manage logins.

• SQL Server 2000 -- Log Shipping reliability?

  - by Chris J

  I've been asked to look into log shipping for SQL Server 2000 (yes, 2000): something in my memory tells me that I looked at this years ago and there were question marks over it's reliability. I'm trying to google stuff, but given the age of 2000 now I've put pulled up anything to confirm this -- most seem to say they're using it without problem, so just want confirm whether I'm just being delusional, or whether there were problems, but with a fully patched SP4 box these don't exist any more. Cheers!

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• Quick way to bypass proxy with DownThemAll

  - by endolith

  I've been using an SSH proxy to my home network to encrypt my internet surfing, which is fine. But the connection is much slower than the direct one, and when I'm downloading large files I'd rather go around the proxy. Currently, I send it to Downthemall, go to FoxyProxy and disable the proxy, cancel and resume the download, then when it's started go back to FoxyProxy and re-enable it. Is there any way I can just get DownThemAll stuff to skip the foxyproxy?

• mailman not relaying email to external address

  - by gozzilli

  I have a setup of mailman with postfix on an ubuntu server 12.04. My problem is that mailing list emails are not forwarded to email addresses external to my institution. However the initial welcome email is received by everyone, internally and externally. in fact, a simple email from command line with mail is successfully sent to anyone after that, mailing list emails are only forwarded to internal addresses. the domain name I'm using for the server is not that of my institution who is hosting the server. Here is my main.cf: myorigin = sub.myinstitution.tld mynetworks = 127.0.0.0/8 xxx.xxx.xxx.xxx/16 # this is my institution ip range relayhost = smtp.myinstitution.tld inet_interfaces = loopback-only local_transport = error:local delivery is disabled virtual_alias_maps = hash:/etc/postfix/virtual smtpd_recipient_restrictions = permit_mynetworks myhostname = mywebsite.tld mydestination = $myhostname, localhost.$mydomain, localhost I also found these two links on serverfault and ubuntu forums, but neither of these solutions seem to do the trick for me. Any help would be much appreciated.

• Using more recent kernel for Xen Dom0 in production.

  - by thelsdj

  Does anyone have experience running Xen dom0 on a more recent kernel than the stock 2.6.18? What host distro are you running? What release of Xen (or hg/git changeset)? What set of patches are you using on kernel source? (Has anyone got the pvops dom0 stuff working in production or is it better to stick with something like the SUSE patches? Any other tips and tricks to running a more recent kernel version as dom0 would be helpful.

• Easiest way to get Perfmon counter names into a text file?

  - by Bill Paetzke

  I'd like to create a settings file for my logman command. I expect to have lots of perfmon counters. Is there any easy way to get all the perfmon counters' exact text anywhere? The only thing I thought of was to create a Perfmon Counter Log through the GUI and then export the list of selected counters--but I don't see an export option! I guess I could manually copy what I see on the screen, but that seems inefficient. I'm going to be dealing with tens of counters. Maybe there is a list somewhere? That'd be easier to copy and paste from.

• Domain pointing to wrong subscription in Plesk 10

  - by Michal Gow

  I recently moved a domain name in the Plesk 10 control panel from one subscription to another. DNS is managed by another server so there is no change in DNS at all. The IP address is shared and remains the same so there is really no need for a DNS change. But the domain is still managed by its former subscription (where it should have been removed from) and is pointing to exactly the same folder as in the past, even when is not in the list of domains there. Subsequently, the new subscription do not have the domain under its control. Even this domain is in list of domains here and points to another folder.

• Can a virus infect an ISO file?

  - by Frederick

  I feel that it's going to be very difficult for a virus to infect an ISO file. What's your experience? Have you seen it happening ever? Is it not nearly unlikely? I ask because I've just found that my computer is infected and I wish to salvage as much stuff as possible. So I was wondering if I could keep my ISO files.

• Does anyone know why rsync would keep sending the files over and over again?

  - by beagleguy

  I'm trying to using rsync to backup some files, about half a TB. It's now it a state where it keeps sending the same files everytime it runs. for example: rsync -av /data/source/* user@host:/data/dest sending incremental file list source/file1.txt source/file2.txt I then verify those files are copied over... then the next time it runs it does the same thing rsync -av /data/source/* user@host:/data/dest sending incremental file list source/file1.txt source/file2.txt any idea why it's getting stuck on these files? I've tried to wipe the whole dest directory out and start over but no luck. thanks,

• Multiple Selections from Dropdown in Word 2011 Form

  - by BR Hudgens

  Anyone know if there is a way to setup a Word form to allow the user to select multiple items from a dropdown list that are then displayed? For example, I need to setup a form to identify applicability of specific procedures to various levels of our organization. Since the listing of all departments under all divisions can be pretty lengthy, I was hoping for the ability to check off a division and then have a dropdown list on the same line to select the applicable departments (so the selections are specific to that division and not all listed on the form if that division is not applicable). First, I'm not seeing how to create a dropdown that would allow multiple selections. Beyond that, I don't know if that form element alone would then display all selected items or if that would require another element of some type. Anyone have any suggestions on this? Thanks in advance!

• How do you determine if your domain isn't AD or ADAM?

  - by icurious

  I'm trying to get some authentication stuff set up in ASP MVC, but keep getting thrown errors about how it doesn't support anything but Active Directory (AD) and Active Directory Application Mode (ADAM). How can I figure out the actual running version of my LDAP provider? Is there some sort of command or query I can run against it? It's entirely possible it isn't AD or ADAM, but I have no idea how to figure that out.

• Tool or script to detect moved or renamed files on Linux prior to a backup

  - by Pharaun

  Basically I am searching to see if there exists a tool or script that can detect moved or renamed files so that I can get a list of renamed/moved files and apply the same operation on the other end of the network to conserve on bandwidth. Basically disk storage is cheap but bandwidth isn't, and the problem is that the files often will be reorganized or moved around into a better directory structure thus when you use rsync to do the backup, rsync won't notice that its a renamed or moved file and re-transmission it over the network all over again despite having the same file on the other end. So I am wondering if there exists a script or tool that can record where all the files are and their names, then just prior to a backup, it would rescan and detect moved or renamed files, then I can take that list and re-apply the move/rename operation on the other side. Here's a list of the "general" features of the files: Large unchanging files They can be renamed or moved around [Edit:] These all are good answers, and what I end up doing in the end was looking at all of the answers and will be writing some code to deal with this. Basically what I am thinking/working on now is: Using something like AIDE for the "initial" scan and enable me to keep checksums on the files because they are supposed to never change, so it would aid on detecting corruption. Creating an inotify daemon that would monitor these files/directory and recording any changes relating to renames & moving the files around to a log file. There are some edge cases where inotify might fail to record that something happened to the file system, thus there is a final step of using find to search the file system for files that has a change time latter than the last backup. This has several benefits: Checksums/etc from AIDE to be able to check/make sure that some media did not get corrupt Inotify keeps resource usage low and no need to re-scan the filesystem over and over No need to patch rsync; If I have to patch things I can, but I would prefer to avoid patching things to keep the burden lower, (IE don't need to re-patch everytime there is an update). I've used Unison before and its really nice, however I could've sworn that Unison does keep copies around on the filesystem and that its "archive" files can grow to be rather large?

• Why does the mouse always move to the bottom left?

  - by AngryHacker

  In the course of doing stuff on the computer, the mouse always moves, by itself, to the bottom left of the screen - I'd say several times in the course of an hour. I thought this might be an issue with the driver, so I re-installed the driver, but the problem continued. Then thinking that the mouse is faulty, I replaced my Microsoft Wheel Mouse with a Dell mouse. The problem still continues. How can I fix this problem?

• Can qmail-ldap replace the validrcptto file?

  - by T. Fabre

  We are using qmail to route incoming mail to our Domino server. However, that requires us to maintain the validrcptto with the list of all allowed email addresses. Since Domino provides an LDAP directory, does qmail-ldap provide functionnality to lookup valid rcpt to addresses in the Domino directory instead of the validrcptto file, so that we wouldn't have to maintain that extra list ? We have about 150~200 users, so is setting up qmail-ldap worth the extra mile if it can verify addresses in the LDAP directory ? If anyone has experience with qmail-ldap and its setup, I'd be glad to hear from you.

• Outlook.com Sweep rule vs Filter rule

  - by Mahesha999

  New outlook.com introduced new sweep option. With it, you can create a filter to move messages from particular sender to a particular folder after certain days the mail comes. This rules gets added to the Filter list. However we cannot edit this rule by clicking Edit in front of it in that list. The dialog appears saying you should delete the rule and create the new one. I don't understand why sweep rules are considered differently from Filter rules? I have 68 filter rules. What if I want to add such time clause to these filter rules so that instead of moving the incoming mails immediately to a certain folder, they will be kept in Inbox for say 10 days and then they will be moved. Such time clause cannot be added to the filter rules. So should I delete all these 68 filters and create new Sweep rules?

• Mailman bounces go to me, do not unsubscribe user! (MacOS Server)

  I run a large mailing list (30,000 users). Every month I get a whole slew of bounces in my mailbox from the "mailing list memberships reminder" that get sent out.

• Identify Long Running or Slow PHP Scripts

  - by Kirk

  I have web server that is getting around 25K visits a day up at yougetsignal.com. Sometimes the site feels a bit sluggish. I am hosting it on nginx with php5-fpm. Is there a way for me to see a list of all of the long running requests that are coming to the site? I'd love to have a real-time list of all of the active requests that PHP is handling and how long they have been running. Kind of like top, but just for the web server. This would let me know how long requests are taking and which script is the culprit. Anyone have any ideas on how I can do this?

• crontab: question about a special case of the dash character in the time field spec

  - by mdpc

  In the SuSE /etc/crontab the entry to run the cron.{hourly,daily,monthly,weekly} scripts is coded as: -*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons /dev/null 2&1 Notice that the very first character of the specification is a dash character (-), and this is NOT a typo. Can somebody explain what the time spec '-*/15' means? BTW, the stuff seems to be running fine. Thanks
