• View changelog of all packages to be upgraded before upgrading

  - by Stein G. Strindhaug

  When using synaptic on my Ubuntu desktop computer i can review all changelog of all the packages to be upgraded, and unselect a package for upgrade if I want. On my desktop I usually install everything, but I like to at least review what the changes are so that I can delay the upgrade if I suspect it could cause problems with the development tools I use. On a server (Ubuntu Server) with no x-server how can I do the same thing on the console: list all packages that will be updated (apt-get --dry-run upgrade does this along with a lot of noisy simulated install messages), view the changelog (if any) from last upgrade to the version it will be upgraded to. select which packages I want to ignore, or which I want to upgrade I've searched a lot for this but I haven't found anything, possibly I'm not using the correct terminology; but surely this must be possible. Synaptic must get it's info from some some low-level tool I assume? Complicated shellscripts are welcome too, if this is not already easily done with the existing tools.

• How to check if cell contains a value of another cell

  - by Antonio Oliveira

  Here is the scenario: On column A each cell has random text within it (names, address, account numbers, etc). Column A extends down to over 40 thousand rows. On column B I have a list of (account) numbers. Column B extends down to about 5 thousand rows. I need to filter column A to show only the rows that contain the account numbers that are part of column B. Neither column A nor B are in any specific order. I think he above scenario speaks for itself, but I can provide a quick example if needed (don't want to over complicate it).

• delete multiple files on linux with spaces in file names

  - by raido

  I have a directory on my Linux box with over 10000 files that I have to delete. Running... sudo rm -rf /var/tmp/* Gives the error message... sudo: unable to execute /bin/rm: Argument list too long The solution to this is to run sudo find /var/tmp | xargs sudo rm This only works for files with no spaces in the file name. However, some of the files have names with spaces in them and they are not deleted. For example, if a file is named 'A File With Spaces in the Name.dat', Running the command gives me errors like this.... rm: cannot remove `/var/tmp/A': No such file or directory rm: cannot remove `File': No such file or directory rm: cannot remove `With': No such file or directory rm: cannot remove `Spaces': No such file or directory rm: cannot remove `in': No such file or directory rm: cannot remove `the': No such file or directory rm: cannot remove `Name.dat': No such file or directory How do I pass the complete file path to xargs sudo rm without breaking up the file name.

• VM: Windows 7 host, Linux guest, VT-d?

  - by chx

  I am sick of the driver issues of Linux. So I am planning to switch to Windows 7 as a host and virtualize my Linux into it. My laptop has integrated Intel graphics and supports VT-d. For speed reasons I would like to assign that card to Linux. Now, Parallels could do it but this page says Note: If you have only one PCIe video adapter, its name will be grayed out in the PCI Devices list and you will not be able to allocate it to your virtual machines. I would be perfectly fine with a headless Windows 7 (I can remotely admin from other computers or just the Linux guest) -- is there any VM software that doesn't have this restriction?

• Boot from Second SATA Drive

  - by Chris

  I have a Dell Precision 490 Workstation, and I just had my other question answered, Install Ubuntu to drive B without impacting drive A, and now I'm having a boot sequence issue. The external drive is great, boots up fine on my laptop, but how do I tell my desktop to boot from my second SATA drive and not the first SATAdrive. My drive configuration as follows SATA-0: Windows SATA-1: DVDR SATA-2: Ubuntu When I choose the boot menu, the option I have is "Internal Hard Drive". I assume it searches all drives, and loads the first bootable one it finds (which happens to be Windows), but I'd like to be able to select the drive from a list. Has anyone experienced this? Is possible without disabling the first hard drive in the BIOS?

• Debian - Can't stop MySQL; permissions?

  - by anon

  I just tried to upgrade from debian squeeze to unstable by replacing 'squeeze' with 'unstable' in /etc/apt/sources.list. The upgrade went smoothly except for mysql, which failed because it couldn't stop mysql. /etc/init.d/mysql stop simply returns that it failed, but if I try to get the status with /etc/init.d/mysql status it gives me this error: me@debian:~$ sudo /etc/init.d/mysql status /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)' . mysql is running fine, and I checked the permissions for debian-sys-maint in phpmyadmin and it's allowed to do everything, but only connect from 'localhost.'

• centos 5.6, virtual on Vsphere

  - by Glasnhost

  suddenly my virtual centos server (5.6 on VMWare-VSphere) is not working... It started with the url not responding, nor the ip. (NO HTTP response, no ping). When I entered on the server via ssh to start troubleshooting I noticed that most of commands don't work anymore: top- machine hangs (it's not slow anyway) ps - machine hangs (funny enough apache server and web app are running and sending me emails) on some directory ls -l - machine hangs after first file, if ls l.txt the file show only the first file "more" command, also hangs on some file. So there are very little things I can try. I recovered my virtual machine from yesterday and before yesterday, and they show the same behaviour, it hangs on commands (but yesterday they were working). There is no firewall on the machine, there is on the host though. I can connect with ftp but I can't download files nor list directory apart the user top directory... Working hard right now, any idea appreciated

• Finding (listing) all Youtube videos embedded under a single domain?

  - by Tylerr

  Is there a way (a google search, maybe?) to list/find all Youtube videos embedded under a single domain? There used to be (if memory servers) an option on youtube, to find all videos from a single site (they were referencing them as "blogs"), but was available for short period of time and it totally disappeared. I was experimenting with a couple google searches, but to no avail, like this one: site:theverge.com intext:"youtube.com/embed" Even if it worked, it wouldn't provide elegant "thumbnailed" results. Anyone has any ideas? Thanks

• Touchpad not working after login in Ubuntu

  - by Maria Mateescu

  At some point my touchpad stopped working on Lenovo x220 under Ubuntu 11.10, after login. I have found two possible solutions for that online, but neither of them work. First, gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true and a second one, xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Off" 8 0 After looking more carefully into xinput I have realized that xinput list-props "SynPS/2 Synaptics TouchPad" outputs: Device Enabled (132): 0 This field seems to be stuck to zero, because trying to set it back to 1 by: xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 8 1 doesn't seem to have any effect, e.g. I still have: Device Enabled (132): 0 Any ideas? Thank you!

• Close lid option "Do nothing" absent

  - by Jaap

  I just unpacked my new Sony Vaio, with windows 8 pro installed. Everything is nice, so I tried setting my power management options. The "When I close the lid" option only list: Hibernate Sleep Shutdown The "Do nothing" option is not present. I've seen loads of stuff on google where people ask or explain how to set this option to "Do nothing", but in all my power plans this option is absent... Can I use a tool to prevent this, or is there a way to force windows to show me this option (and that it actually works)? UPDATE powercf /q guid gives me this output: Subgroup GUID: 4f971e89-eebd-4455-a8de-9e59040e7347 (Power buttons and lid) GUID Alias: SUB_BUTTONS Power Setting GUID: 5ca83367-6e45-459f-a27b-476b1d01c936 (Lid close action) GUID Alias: LIDACTION Possible Setting Index: 000 Possible Setting Friendly Name: Sleep Possible Setting Index: 001 Possible Setting Friendly Name: Hibernate Possible Setting Index: 002 Possible Setting Friendly Name: Shut down Current AC Power Setting Index: 0x00000000 Current DC Power Setting Index: 0x00000000 Other sections have different enumerations where 000 stands for No action

• Sharepoint 2007 reset permission inheritance

  - by e-mre

  I have this SharePoint 2007 document library which has several levels of folders and files. Some folders in the middle of the hierarchy do not inherit permissions from their parents and have their unique permissions defined. It is a huge library and there are many folders like this. I am currently changing the permission model of my library and I want to reset all those unique permissions and have all of them inherit permissions from the library root. (Something like "Replace child object permissions" checkbox available in windows files system security window) If this is not possible, seeing a list of folders that have their unique permissions defined would also do.

• Determining the State of a User using their Hostname

  - by PhpMyCoder

  Not sure if this is the right SE site. I figured this question doesn't belong on SO, but if you think it doesn't belong here either, I apologize. I've been looking into determining the location, specifically the state, of a user accessing my website. One of the options I've known about for a while is the GeoIP City Database, however this isn't the most cost effective solution and I'm cheap so I was looking for a less expensive way. Something that occurred to me was that my state was in the public hostname assigned to me by Comcast: (Dash Separated IP).hsd1.ma.comcast.net Could it be possible that other ISPs follow this same pattern of inserting the state abbreviation into their users' hostnames? I've been looking around for a list of hostnames for other ISPs, but I haven't found anything. Can anyone verify that this holds true for other major ISPs?

• Trying to install PHP 5.2 on IIS/Win 2008 - Error 500

  - by Razor

  I have a fresh install of IIS 7 - I just added Web Platform Installer, and PHP 5.2 thru that. However, when trying to access to a simple test.php file (just has phpinfo() in it), I get the following list of errors: • IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly. • IIS was not able to process configuration for the Web site or application. • The authenticated user does not have permission to use this DLL. • The request is mapped to a managed handler but the .NET Extensibility Feature is not installed. The domain was created with dot net panel, but I don't think that has to do with this problem, unless maybe it uses a specific user? Maybe I need to add php thruough dot net panel? Any idea of what I'm doing wrong here?

• Use System Restore to rescue lost user profile in Win XP?

  - by im_chc

  Hi! My win XP account profile has recently been "reset". Many app settings are lost. For example, the "recent project" list in VS 2005 is empty. There should be lots of other stuffs that are painfully lost without me knowing! What can I do? Can I retrieve the app settings from System Restore? I don't have much confidence on this util, even tho I think restoring to a point when the profile still works, and back up away the C:\Documents and Settings (is it where all the app setting files are located?), that should work... Is it reliable to restore to a previous restore pt and then goes back to the latest RP? I've googled on System Restore, looks like what the util does is just back up some physical files, and restore them when doing System Restore. That sounds quite safe, but I am still uncomfortable to this. Thx for u guys' help in advance!

• Powershell enters foreach loop with null object

  - by SteB

  I'm listing all backups in a given directory: $backups = Get-ChildItem -Path $zipFilepath | Where-Object {($_.lastwritetime -lt (Get-Date).addDays(-7)) -and (-not $_.PSIsContainer) -and ($_.Name -like "backup*")} If I set it to deliberately return no files (.addDays(-600) then the following prints "Empty" (as expected): if (!$backups) { "Empty" } If I try to list the names with an empty $backups variable: foreach ($file in $backups) { $file.FullName; } I get nothing (as expected), if I change this to: "test"+ $file.FullName; then I get a single "test" under the "Empty". How is this possible if $backups is empty?

• Windows 8 - uninstall AppFabric?

  - by downatone

  I recently upgraded from Win 7 - Win 8. AppFabric was not one of the programs that came up as being incompatible when I ran the upgrade wizard, so I did not uninstall it. Now whenever I goto "Add or remove features" I get the following error: --------------------------- Windows Server AppFabric Setup Wizard --------------------------- Windows Server AppFabric is not supported on current operating system Windows 8 Pro(version 6.2.9200.0). Please refer to installation guide for the list of supported operating systems. --------------------------- OK --------------------------- Unfortunately the only way to uninstall AppFabric is via the "Add or remove features" - does anyone know a commandline command to kick the uninstall so I can at least access "Add or remove features"?

• How to Read XML and Generate SQL Insert

  - by hackerkatt

  I am trying to write a VB Script to read a XML file (downloaded daily) and insert the information into a MSSQL DB. The content of the XML is a list if CDRs (Call Data Records). I need to parse the file and insert the cdr's into a table. I'm a Ruby,Perl,PHP,Javascript,SQL,... programer. But I've really never written any VB Script. I've done some googling and find a number of examples on how to generate XML from a SQL Query, but not the reverse. Any help/suggestions would be greatly appreciated. Thank you!

• Blocking facebook's Like button in firefox

  - by Quiark

  Many sites today use widgets from facebook such as the Like button, list of friends who are fans of that site and so on. While it may be a nice feature, I perceive it to be a serious privacy intrusion, because facebook most likely stores information about which sites you visit. I also heard that when you are not logged into facebook, it still tracks the sites you visit (probably with a cookie) and once you log in attaches the data to your real account. For now, I want to keep using facebook, but I would like to block just these widgets so it can't track me. Is there any Firefox extension which could do that?

• Less daunting front end for SQL Server

  - by Martin

  We currently have a few users who have been using Access very succesfully to throw around large amounts of data. We've now got to the point where the data is just too large to be held in Access, as well as wanting to hold it in a single place where multiple users can access it. We have therefore moved the data over to SQL Server. I want to provide a general tool that they can use to view the data on the server and do some simple things like run queries and filters and export the data for offline manipulation. I don't want the support headaches that might come with rolling out SQL Management Studio, and neither do I want to have to create an Access database with links for each current database or ones that are created in the future. Can anyone recommend a simple tool that will connect to a server, list all the databases and allow a user to drill into a table and look at the data. Many thanks.

• How to stream multiple files on demand in VLC?

  - by romkyns

  Is there any way at all that I can set up VLC on a server PC in such a way that I can access a list of all my videos from another PC, and pick one to be streamed on demand? I've been pointed at this streaming guide (pdf), but it's pretty useless. For a start, most of the menus in those screenshots don't match the actual current version VLC, and then it sort of assumes you already know what you're doing. So far I managed to figure out how to stream a single file, which I must choose before watching on the server PC - pretty useless if you ask me! The impenetrable "UI" doesn't help either... (P.S. The reason I'm going for streaming rather than the very simple to set up network drive is described in this question)

• Visual Studio Express 2012 - Moving items to tab control loses actions

  - by JohnP

  VS 2012 Express on Windows 7 Professional, this was pre SP1 install. I have a windows form that I had several elements (Listboxes, buttons, text and labels), with some actions associated with changing indices on the list boxes and of course the button actions. I decided I wanted to add a tab control to enable a second tab with a different feature set, so I copied/cut/pasted all of the original items to a tab control that I added. When I did this, all of the elements lost their click action in the events window. I had to go and re-associate all of them. Is this a normal behavior/known issue, or is there some method to move controls that I am not aware of?

• Wireless WAN (WWAN) on a Lenovo T500 - built-in or do I need a WWAN modem?

  - by Justin Grant

  I use a Lenovo ThinkPad 2055-3AU at work and I want to get a Wireless WAN data plan with a local mobile telecom provider. I've read conflicting reports online about whether my system is "WWAN-ready" or not. How can I find out which wireless WAN providers (if any) my system can support without buying a separate modem? I looked through Device Manager for anything resembling a WWAN device and didn't see anything, but I also wiped the machine when I bought it and clean-installed Windows 7 with only out-of-the-box Windows and Windows-Update drivers, so it's possible that the device is there but the drivers aren't installed. FWIW, the support page at http://www-307.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=20553AU does not specfically list anything about Wireless WAN.

• Write hash password to LDAP when creating a new user

  - by alibaba

  I am working on a project with a central user database system. One of the requirements of the system is that there should be only one set of users for all the application. FreeRADIUS and Samba are two my applications that both use LDAP as their backend. Since users must be the same for the entire system that contains many other applications, I have to read the list of users from the central database and recreate them in the LDAP directories for Samba and FreeRADIUS. The problem is that users are sent to me from another entity and I can save them in the database with their hash passwords. I don't have access to their cleartext passwords. I am wondering if I could enter directly a hash password for a new user in LDAP with my preferred hash mechanism. If not, can any one tell me what strategy I have to use? I am running my server on UBUNTU 12.04 and all other applications are the latest versions. My database system is PostgreSQL 9.2. Thank you

• Set an Excel cell's color based on multiple other cells' colors

  - by Lord Torgamus

  I have an Excel 2007 spreadsheet for a list of products and a bunch of factors to rate each one on, and I'm using Conditional Formatting to set the color of the cells in the individual attribute columns. It looks something like this: I want to fill in the rating column for each item with a color, based on the color ratings of its individual attributes. Examples of ways to determine this: the color of the category in which the item scored worst the statistical mode of the category colors the average of the category ratings, where each color is assigned a numerical value How can I implement any or all of the above rules? (I'm really just asking for a quick overview of the relevant Excel feature; I don't need step-by-step instructions for each rule.)
