  • whats the difference between GPU and framegrabber?

    - by user261002
    I am working on a project to monitor if human tissue has been fused with radio frequency during the surgery or not, therefore we are using a very fast camera (1800fps) and also laser illumination on the tissue and a framegrabber (1GB memory). I notice that, instead of a framegrabber, I'm able to use GPU as well, but I am not sure on what's the difference between them? Can any body explain what is the difference between a frame grabber and a GPU?

  • assign, not toggle, category

    - by Hemal Pandya
    The Home/Categorize option in ribbon on Outlook 2010 toggles categories. If a group of mails is selected where some of the mails already have the selected category assigned then the action removes the category from those mails and assigns to the rest. I view mails grouped by conversation and would like to repeatedly assign a category to all mails in the group. I can clear all categories before assigning, but that would work only if the mails have only one category assigned. Ideally, I would like to change the behavior of the existing button. If not, a different menu option or shortcut. Is there a way to do either of this?

  • Groups and Symlinks, is this safe?

    - by sjohns
    Hi, Im trying to serve similar content over two websites, but don't want to have 2 of each file, especially when they are growing. The basics, im running CentOS, with cPanel. Is it safe to do the following, I have folder downloads1 in /home/user1/www/downloads1/ i have user2, can i make a group - groupadd sharedfiles add both users to the group: useradd -g sharedfiles user1 useradd -g sharedfiles user2 then chown -r -v user1:sharedfiles downloads1/ User 2 i want to have /home/user2/www/downloads1 but i want it to be a symlink like ln "downloads1" "/home/user1/www/downloads1/" lrwxrwxrwx 1 user2 sharedfiles 11 May 9 14:20 downloads1 -> /home/user1/www/downloads1/ Is this a safe practice? Or is there a better way to do this if I want them both to be able to share the files for distribution over apache. Is there any drawbacks to this? Thanks in advance for any light shed on this. I'm not 100% sure weather this should have gone here or on serverfault.

  • A proper way to create non-interactive accounts?

    - by AndreyT
    In order to use password-protected file sharing in a basic home network I want to create a number of non-interactive user accounts on a Windows 8 Pro machine in addition to the existing set of interactive accounts. The users that corresponds to those extra accounts will not use this machine interactively, so I don't want their accounts to be available for logon and I don't want their names to appear on welcome screen. In older versions of Windows Pro (up to Windows 7) I did this by first creating the accounts as members of "Users" group, and then including them into "Deny logon locally" list in Local Security Policy settings. This always had the desired effect. However, my question is whether this is the right/best way to do it. The reason I'm asking is that even though this method works in Windows 8 Pro as well, it has one little quirk: interactive users from "User" group are still able to see these extra user names when they go to the Metro screen and hit their own user name in the top-right corner (i.e. open "Sign out/Lock" menu). The command list that drops out contains "Sign out" and "Lock" commands as well as the names of other users (for "switch user" functionality). For some reason that list includes the extra users from "Deny logon locally" list. It is interesting to note that this happens when the current user belongs to "Users" group, but it does not happen when the current user is from "Administrators". For example, let's say I have three accounts on the machine: "Administrator" (from "Administrators", can logon locally), "A" (from "Users", can logon locally), "B" (from "Users", denied logon locally). When "Administrator" is logged in, he can only see user "A" listed in his Metro "Sign out/Lock" menu, i.e. all works as it should. But when user "A" is logged in, he can see both "Administrator" and user "B" in his "Sign out/Lock" menu. Expectedly, in the above example trying to switch from user "A" to user "B" by hitting "B" in the menu does not work: Windows jumps to welcome screen that lists only "Administrator" and "A". Anyway, on the surface this appears to be an interface-level bug in Windows 8. However, I'm wondering if going through "Deny logon locally" setting is the right way to do it in Windows 8. Is there any other way to create a hidden non-interactive user account?

  • Can send to individual users but not when they are in a global distribution list.

    - by Jake
    I am able to send email to individual users but when not when they are in a distribution group. When I do I get this report. The message could not be delivered because the recipient's destination email system is unknown or invalid. Please check the address and try again, or contact your system administrator to verify connectivity to the email system of the recipient. #5.3.1 However, like I said before I can select their name from the GAL and send mail that way. Their email address is exactly the same in both the GAL and distribution group. The only difference is these users have external email addresses. Windows Server 2003 Exchange Server 2003 Outlook 2007 and 2010.

  • Any way to recover ext4 filesystems from a deleted LVM logical volume?

    - by Vegar Nilsen
    The other day I had a proper brain fart moment while expanding a disk on a Linux guest under Vmware. I stretched the Vmware disk file to the desired size and then I did what I usually do on Linux guests without LVM: I deleted the LVM partition and recreated it, starting in the same spot as the old one, but extended to the new size of the disk. (Which will be followed by fsck and resize2fs.) And then I realized that LVM doesn't behave the same way as ext2/3/4 on raw partitions... After restoring the Linux guest from the most recent backup (taken only five hours earlier, luckily) I'm now curious on how I could have recovered from the following scenario. It's after all virtually guaranteed that I'll be a dumb ass in the future as well. Virtual Linux guest with one disk, partitioned into one /boot (primary) partition (/dev/sda1) of 256MB, and the rest in a logical, extended partition (/dev/sda5). /dev/sda5 is then setup as a physical volume with pvcreate, and one volume group (vgroup00) created on top of it with the usual vgcreate command. vgroup00 is then split into two logical volumes root and swap, which are used for / and swap, logically. / is an ext4 file system. Since I had backups of the broken guest I was able to recreate the volume group with vgcfgrestore from the backup LVM setup found under /etc/lvm/backup, with the same UUID for the physical volume and all that. After running this I had two logical volumes with the same size as earlier, with 4GB free space where I had stretched the disk. However, when I tried to run "fsck /dev/mapper/vgroup00-root" it complained about a broken superblock. I tried to locate backup superblocks by running "mke2fs -n /dev/mapper/vgroup00-root" but none of those worked either. Then I tried to run TestDisk but when I asked it to find superblocks it only gave an error about not being able to open the file system due to a broken file system. So, with the default allocation policy for LVM2 in Ubuntu Server 10.04 64-bit, is it possible that the logical volumes are allocated from the end of the volume group? That would definitely explain why the restored logical volumes didn't contain the expected data. Could I have recovered by recreating /dev/sda5 with exactly the same size and disk position as earlier? Are there any other tools I could have used to find and recover the file system? (And clearly, the question is not whether or not I should have done this in a different way from the start, I know that. This is a question about what to do when shit has already hit the fan.)

  • restrict windows remote desktop

    - by radioactive21
    Is there any way to prevent users from launching and using remote desktop and to restrict it to only local admins or domain admins? The reason being is that we do not want users to remote desktop home, but at the same time we want it to be available to certain users like administrators or power users. Ideally there is a group policy that can be set to groups or users who have access to the remote desktop application from their machine. Clarifications: I need the machine to be able to still have remote desktop work, just only with a specific user or group. The point is that we allow certain users to use remote desktop and others to not have access to it. There are machines where there are multiple users, so we cant just block a whole machine or by IP. This needs to be done per a user account or login.

  • OS X server 10.6 - how to restore default groups?

    - by Zoran Simic
    I've set up my OS X server as an open directory master first, then (experimenting), I've changed it to standalone server, then set it back as an open directory master again. Now, all the default groups I saw before are gone (Domain Administrators, Domain users etc). Do you know how to restore these groups? Note that the groups are gone only from the Workgroup Manager UI. They do seem to be still there otherwise. id -G gives the usual list of groups. If I create an account and makes its primary group 'staff', Workgroup Manager shows all the inherited groups properly (but not on the main list). If I create an account and associate it to a new group I just created, then the account has no inherited groups...

  • Stuck on Login PhpMyAdmin

    - by TMP
    Hi. I've isntalled phpmyadmin via apt-get. I've set the apache env-vars to the correct user:group. I've set ownership of /etc/apache2 and /etc/phpmyadmin to this user:group. I've restarted both apache2 and mysql several times. My Problem: When I access [ServerIP]/phpmyadmin I get the login screen, I enter the information, and i'm right back at the login screen, with not even an error "permission denied" or "password wrong" or whatever. The only things thats different is the URL: Instead of the Original http://[ServerIP]/phpmyadmin/index.php I am now at http://[ServerIP]/phpmyadmin/index.php?token=[Long Hex string here] However, still the login dialog. My Question: How Do I fix this?

  • Different buddy lists for different accounts in iChat

    - by Idlecool
    I have currently 4 accounts added to iChat, Standard GTalk GTalk For Google Apps Facebook Olark Facebook and Olark have their own Buddy List Group viz. Facebook and WebUser groups and thus those buddies come in a separate list, while the buddies from GTalk and GTalk from Google Apps do not have any group associated with them and they come under Buddies list. It's a bit of a pain because I want to have buddies from GTalk for Google Apps in a separate buddy list than the default one. Is it possible to do it in iChat?

  • MSSQL: Choice of service accounts

    - by Troels Arvin
    When installing MS SQL Server 2008, one needs to associate a service account with the installation (possibly even several accounts, one for the SQL Server Agent, one for Analysis Services, ..., but let's leave that for the case of simplicity). The service account may be local account, or a Windows domain account. If a domain account is used: Can MSSQL start, if connectivity to the domain controllers is temporarily down? If the answer is yes: Should each DBMS instance on each server have a separate account, or does it make sense to use a particular "MSSQL" domain account on all MSSQL-installations in the organization? If separate accounts are used for each instance on each server: Does it make sense to create a special MSSQL security group in the domain and place all the MSSQL service accounts in that group, perhaps to ease replication, etc? Is there a common, generally accepted naming convention for MSSQL service account(s)?

  • unable to properly execute binaries from PHP

    - by Lowgain
    I was building an app on a SUSE box, and had a binary called create_group for instance, which had a suid bit and allowed my PHP app to call exec('create group grpname'); and create a new group (there are others for users, etc). The binary was a small c script that calls setuid(0) and then runs the user creation stuff. This worked perfectly on the SUSE box I recently moved my project to Ubuntu and everything works fine except these binaries. I can run them from the shell and they work okay, but when I get the PHP app to run them it just does nothing. Is there anything Ubuntu would be doing differently that I'm missing?

  • Email client wont connect to SMTP Authentication server

    - by Jason
    Im having trouble installing SMTH Auth for my ubuntu email server. I have followed ubuntu own guide for SMTH AUT (https://help.ubuntu.com/14.04/serverguide/postfix.html). But my email client thunderbird is giving this error " lost connection to SMTP-client 127.0.0.1." I cant add new users to thundbird either because of this connection problem.

  • Share in inbox in Google Apps Standard

    - by Saif Bechan
    I have recently signed up for the Standard account of Google apps. In my company I have certain email addresses that are handled by multiple users. For example the support emails are handled by multiple users. Now I have just multiple users log into the same account, but this is not a good practice. It can get quite messy when some emails are handled by different users but on the same email address. Now I looked into the groups option. I have made a group for [email protected], and added all the users to the group. Now everybody gets a copy of the support message sent. But its got a bigger mess because the users don't know who handles which message. Is there some workaround to this so I can make good use of this all in this way.

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • Add Bookmark to IE automatically for new users on a computer

    - by Kyle Brandt
    When I set up a PC, I would like to be able to have it so when anyone logs into that PC from the domain a couple of IT bookmarks will be in IE. I read I can do this with a Domain-Level group policy, but unfortunately, with my current domain group policies have not gone well, so I have fear (Rather not get into this in this question). Can I do this at the PC level when I deploy a new computer? So any domain users who log into the PC will have these bookmarks added when their profile is created (no roaming profiles). These are XP machines, and the domain is run by 2003 controllers.

  • Diff and ignore lines missing in one file

    - by Millianz
    I want to diff two files and ignore lines that are present in one file but missing in the other. For example File1: foo bar baz bat File2: foo ball bat I'm currently running the following diff command diff File1 File2 --changed-group-format='%>' --unchanged-group-format='' Which in this case would produce bar baz as the output, i.e. only missing or conflicting lines. I would like to only print conflicting lines, i.e. ignore cases where one line is missing from File2 and is present in File1 (not the other way around). Is there any way to do something like this using diff or do I have to resort to other tools? If so, what would you recommend?

  • Linux: Can I link multiple destinations via softlinks?

    Attempting to end up with something similar to this: $ ls -l lrwxrwxrwx 1 user group 4 Jun 28 2010 foo -> /home/bar lrwxrwxrwx 1 user group 4 Jun 29 2010 foo -> /etc/bar The intention is to be able to move a file to foo & have it go to both destination directories for now. The goal is to eventually unlink /home/bar link after confirming there are no issues with moving the files to /etc/bar. I am restricted in that I am unable to change or add to the process that moves the files.

  • Network Role based routing

    - by Steve Butler
    Apologies my networking skills are a tad rusty. I'm looking for a way to setup a system that gives me the ability to setup Role-based access to specific network resources. For example, i have three private subnets for specific groups, users will need access to one one or more subnets. I'd like to have all client machines on the same subnet/vlan, and then use 802.1x to authorize into a router(NAC device/whatever), the router would then see what user had authenticated(huge plus if it could determine AD group), and then allow routing to one or more of the three private subnets based upon their group membership. I've looked at packetFence, and it appears to work by assigning a client to a VLAN, but i'd still need a way to route some users into different back-end networks.
