• Audio Line-In on Ubuntu/Linux Mint

  - by hahuang65

  I'm currently on Windows, and want to switch to Linux, but some hardware issues are preventing me. Mainly, I have a sound card that supports Line-In. On Windows, anything I plug into the line-in gets outputted to the speakers. However, when I installed Linux, because there is not a control application that comes with the driver, I have no idea how to set this up. I tried going to the sound settings and it doesn't seem to be there. I also want to configure it for 2.1 sound, and do not know how to do that... Anyone here done it before? Thanks in advance for the help!

• Change base language of Windows 8 Installer

  - by Firedragon

  I have access to Dreamspark and Windows 8. When I picked the version I picked English which is fine, but it is US English however I realised I should have picked UK English instead. You are only allowed one version so i cannot switch it. Now, I can change the language pack later to UK English but in the language bar US English is always listed and seems impossible to remove and system restore reverts to US English. Is there a way to fully change the base language to UK in the installer, so in effect makin the installer offer US and UK English, or just UK English as if I had chosen the correct version?

• Wireless option grayed out in Windows Mobility Center

  - by thomasvdb

  We currently have a Lenovo ThinkPad L512 which can't connect to wireless networks. He simply indicates he can't find any networks. Other notebooks (also ThinkPad L512-notebooks) in the company do find the network so nothings wrong with the configuration of the wireless router. As indicated on answer.microsoft.com, I should check Windows Mobility Center and enable the entry "Turn Wireless On". Unfortunately this option has been grayed out. How can I enable this option? There isn't a physical switch on the laptop to turn on the wireless.

• tricks for speeding up tar while tarring up a huge directory of little files?

  - by Trevor Harrison

  I'm trying to tar up a directory that has about 3M tiny files in it. Tar is chugging along, but I'm thinking its going to take longer than I can wait. I'm wondering if telling tar to not store metadata (owner, group, perms) would reduce the churn on reading and re-reading this huge directory and maybe speed things up, and if there is a tar switch that does this. My initial perusal of the man page only gets me something like --no-xattrs, which looks like a start, but I was hoping someone had some specific knowledge.

• With Bash + iTerm2, how to name tabs?

  - by Problemaniac

  In iTerm2 (Build 1.0.0.20120203), I typically open several tabs, each of which has split panes , and is about one particular theme of work, for example revision control, coding, managing files, mysql terminal work. I typically need to switch between 5 or more tabs in my work flow. It is sometimes hard to remember or tell which is which by looking at the content of the screen. I'd like to name the tabs somehow, so I can quickly tell which is which by quickly glancing. Is this possible?

• Excel - Chart that sums the values in multiple rows for each series

  - by Chaulky

  Suppose I have a spread sheet that looks something like this... Now, I'd like to create a column chart that has 3 series, one for each country. Then, I want series for each category, but I want to plot the total, not each individual order total. So, something like this (excuse the horrible artwork)... The data label placement isn't all the important, the key is that for each Category (Bikes and Clothes) I chart the total for each country, not individual values from the "Order Total" column. Is this possible? Is it possible to do the same idea, but to switch Country and Category around?

• Is it possible to group chrome extension processes?

  - by Shajirr

  I have a problem with Chrome - most extensions, even those which consume merely 5-10 MB of memory, each have their own process, and because of that Chrome uses a single process for all the tabs, which consume a lot more memory compared to extensions, even with --proccess-per-tab switch. This behavior seemes illogical - why do you need extensions in separate processes if you can't use your browser properly when it takes 5-10 seconds just to load a tab and freezes constantly? Is it possible somehow to limit the number of processes which can be used for extensions, maybe group them to 10 extensions per 1 process?

• ESXI 4.0 Slow response in opening anything accross the network on a Virtual Server running Win2008

  - by user40944

  Hi I recently installed a HP ML350G6 Server with Windows Small Business Server 200864bit, Exchange 2007. The server was running fantastically and we transferred all user data onto the new server and no problems for 2 weeks! We then installed SQL2008 and transferred the accounts package onto the server and this is where the problems started. Users are now complaining to open a work document can take 2 minutes and the same with regard to anything else. The server itself seems fine, the virtual server seems fine! No disk performance problems (doesn't go above 50% unless i really copy lots of things), no memory, (12Gb only using 7Gb) cpu (usage is low average about 15%) etc on both the VM and in Windows Task manager. I have made sure disk caching is enabled on the raid controller (which made no difference). Network cards are running 1Gb and plugged into HP GB switch. Please help!

• Viewsonic monitor keeps showing its on-screen menu incessantly

  - by markvgti

  Since yesterday my Viewsonic 22" monitor (VX2255wmb) keeps showing its on-screen menu incessantly, without my touching any of its buttons. The menu comes on in the centre of the screen, stays on for 8-10 seconds, disappears for a second or two, then repeats the cycle. This happens whenever there's a signal being sent to the monitor. I can't actually navigate the menu when it appears on-screen. Pressing the power button, or the Up and Down buttons on its right edge dismiss the menu, only for it to reappear again. These symptoms have appeared before, but earlier they'd stop after 5-10 mins. The power button on the monitor has always been iffy, but now it doesn't seem to be working at all--have to switch off power supply from mains when I leave my desk. Using DVI input on this monitor as my HP desktop has DVI output.

• Adding Command-Line Switches To Windows Shortcuts

  - by jaytea

  Is there a way to, in general, create a Windows shortcut to a file and instruct Windows to pass certain switches to the application before passing the filename? For example: I have an Excel file, abc.xlsx. If I want to create a shortcut to open this file read-only, I would change the target to "C:\Program Files\Microsoft Office\Office12\EXCEL.EXE" /r abc.xlsx, but this fails when another person on my network opens the shortcut and their EXCEL.EXE is not in that same folder. Surely there's a way to tell Windows to pass the /r switch without supplying the path/filename of the application that is supposed to open the file?

• is using Hosts for resolving a sql-server more performant?

  - by Ice

  Hi, we have a legacy application which uses a access.mdb with hundreds of ODBC-connected tables on a sql-server. the access.mdb contains nothing else than these odbc-connections. Now we consider to use a virtual sql-servername for these odbc connections and resolve it in the local hosts-file with the ip-address of the real sql-server. Like this we can easy switch between a test-sql-database server and the the server for production in changing one single entry in the hosts. EVERYTHING works fine and now comes the question: Could it be that this is more performant because there is one single point on resolving the sql-server (name or ip-address)? Is there something like a network-cache / DNS-Cache? peace Ice

• Transfer disk image to larger/smaller disk

  - by forthrin

  I need to switch the hard drive on a 2006 iMac to a new SSD. I don't have the original installation CDs. I know I can order CDs from Apple, but this costs money. Someone told me it's possible to rip the image of the old drive and transfer to the new drive. If so, does the size of the new drive have to be exactly the same as the old? If not, my questions are: Is it possible to "stretch" the image from 120 MB disk to a 256 MB disk (numbers are examples)? If so, what is the command line for this? Likewise, is it possible to "shrink" an image from a larger disk (eg. 256 MB) to a smaller disk (eg. 120 MB), provided that the actual space used on the disk does not exceed 120 MB? How do you do this on the command line?

• Explaining svn / apache permissions error? (I know "how" but not "why")

  - by Neil

  I have the following error occurring on occasion when trying to do an svn switch (have it set up to do via a web request): svn: Can't open file '/root/.subversion/servers': Permission denied This happens after an apache httpd.conf change and corresponding restart. How to fix this? I can get it to fix by doing an apache restart - BUT, it often takes multiple tries. Curious if anybody can explain this. Why did this error go away on my 8th apache restart, but not on the prior ones (with no edits to the conf file)? Basically, I kind of have a "how" in terms of solving this, but I don't have a "why" . . . Thanks!

• Screen tail -f window closes immediately

  - by t.heintz

  I have this in my ~/.screenrc file: startup_message off screen -t top 0 top screen -t log 2 tail -f /path/to/application/log/* screen -t action 1 #caption always "%?%F%{.R.}%?%3n %t%? [%h]%?" hardstatus alwayslastline "%-Lw%{= BW}%50>%n%f* %t%{-}%+Lw%<" When I start screen, it opens all three windows, but as soon as I try to switch to window 2, it closes immediately. I would assume there is a problem with the shell and it exits instantly, but I can't find anything wrong with it. I have tried using quotation marks around the path and the entire command, which only leads to "file not found" errors. The command works just fine when I enter it directly into a shell. The screen version is: Screen version 4.00.02 (FAU) 5-Dec-03 Help?

• How can I turn off flash fill automatically in Excel 2013?

  - by user3480643

  Flash fill breaks a lot of things in older excel documents. It causes maddeningly slow transfers from cell to cell after updating. I am trying to find a way to turn off "flash fill" in Excel 2013 automatically before rolling the product out to the rest of the staff in my company. Is there (preferably) a registry key that I can apply or a switch that I can include during the install that will turn this option off? Here is an image of the setting that I am looking to turn off: I haven't been able to find any documentation online about turning this off, other than this one page from MS: http://office.microsoft.com/en-ie/excel-help/turn-flash-fill-on-HA104043292.aspx

• Xmodmap: six characters to one key and two layouts?

  - by sup

  I know how to have six symbols on one key thanks to this question: Xmodmap: Six characters to one key? However, when I have two layouts and switch them, weird things happen. I have the following (well, different, but this is easier to talk about) line in my xmodmap: keycode 31 = a A b B c C When I log in, everything works as you would expect. Pressing key 31 give a, with Shift A, with AltGr c and C respectively and with ISO_Level3_Shift. However, when I change the layout, key 31 gives me b and B with shift and c and C with AltGr. This is on Ubuntu 11.10 under Ubuntu. Does anybody undestand what is happening? Could I restrict xmodmap to just one layout?

• Prevent Virtualbox intercepting certain key combinations?

  - by Blazemore

  Is it possible to prevent my Windows 7 guest OS intercepting Ctrl+Up/Down, and allow my Ubuntu how to intercept them instead? I have a dual-monitor setup with two vertical virtual desktops on Ubuntu. I have a Windows 7 fullscreen guest on one monitor, set to always display on the current workspace. This means I have effectively two vertical workspaces on one monitor, and just Windows 7 on the other. The problem occurs with Windows 7 is focussed and I hit Ctrl+Up/Down to switch workspaces. I have to click out of the VM first, which breaks my workflow. Can this be fixed?

• options for physical architecture of rails site regarding caching server or cdn

  - by timpone

  I have a rails app that is set on a single server currently. On production, I force_ssl for everything. I am interested in using a caching server for images (I'm fine with css and js being served from origin for time being). Would nginx or varnish (which I have no experience with) be a better solution (for October 2012)? I'd imagine that it would be easy to switch these around while still on this single server architecture. Or would something like cloudfront (which I also have no experience with) make sense for hosting image files? I know this is a vague question but appreciate any current feedback. thx in advance

• ALT+TAB doesn't work properly in Windows 8.1

  - by Marco1

  Holding ALT+TAB will activate the flip 2D to switch from a window to another. The problem is that this function remains active for a very short time and I'm not able to select the window I want in the foreground. I also noticed that when I put the cursor on an icon on the taskbar, the live preview thumbnail disappears quickly. With a safe mode restart the problem is no longer there, all is fine! With a clean install of Windows 8.1(no driver and applications installed) the problem is here again; obviously disappears with a safe mode restart also in this situation. What's the problem? A Windows process or service?

• cloud hosting with only root partition

  - by user123198

  We are starting a website possibly with couple of thousands hits every day and few thousands registered users. By our hosting provider we were adviced to go with cloud hosting which we can easily expand later if we need. It is Ubuntu 11 running in WM. The problem we run into is the disk is divided only in root and swap partition which is not advised from security point of view. When consulting this with technical support we got the reply that it is not possible to make more partitions and that it is mainly issue with windows server and linux is generally fine. I'm looking here for an advice if we should switch the hosting for perhaps dedicated server where we have the full control or it is something not too be worried about too much.

• Remove dual boot screen

  - by DoubleP90

  some time ago i bought an SSD and since i had to reinstall windows i bought windows 8 with it. I kept windows 7 on my old HDD and i installed Windows 8 on the SSD. For some time i had both, and a dual boot screen would allow me to switch between them. But now i deleted the windows 7 partition and merged it to the partition where i keep all my files, movies etc. But i still have the dual boot screen showing up with windows 8 and windows 7 options. How can i remove the dual boot screen and just make it boot to windows 8?

• Migrating from Desktop PC to real Server

  - by tevlon84

  i am a student, working as a part-time Administrator at a startup. I never ever used a real Server ( only a Desktop Pc with apache ) The Company i am working for is growing and they want to switch to a real Server. My idea would be to use the Ubuntu build-in Backup function and use this Backup file as Base for the Rack-Server, but i don't know, which problems i would run into. Is it a good idea ? So basically my question is : *What is the easiest way to migrate from a Desktop PC to a real Rack-Server? ( on an Ubuntu Server) *

• Can't connect to server from certain machines

  - by Joel Coel

  On a small college campus we have a VLAN setup for the computer labs. These machines get assigned IP addresses in the 192.168.7.xxx range. In the server room, all of the server are on the default VLAN and assigned an IP address in the 10.1.1.xxx range. For the most part this works, but the lab machines are unable to connect to one of the servers. They can't even ping it. They can talk to other servers on the same switch as this server just fine. At first I thought it might be a vlan issue, but I changed the server port vlan to match other known-working ports with no effect. Any ideas?

• Network connectivity issue

  - by kubiej21

  I am a novice cisco user and I am trying to investigate as to why one of our connections went down. We have a fiber network ring that is operating just fine. Connected to this ring via ethernet, is a lone 3560. This connection has worked flawlessly for the past year and a half. This morning, I noticed that I could not connect to that remote switch. I checked the configurations on both switches, and nothing has changed (as I expected). In the field, the port lights were flashing, indicating that some sort of communication is occurring. There is only 1 ethernet cable that has been run between these two locations, so testing an alternate path is not possible. What else can I do to fix this connection?

• Remotely enter encryption key?

  - by Jason Swett

  This might be a really dumb question but here goes, anyway. I just bought a couple servers. I already installed Ubuntu with encrypted LVM on one and I'm planning on doing the same with the other. This means that every time I boot up each of these machines, I have to enter the passphrase. And I'll have to do this every morning because I'll power each machine off each night for security reasons. Here's the problem: I don't have monitors or keyboards for these servers. It seems to me I have two options: Somehow enter the passphrase remotely Buy a KVM switch I doubt #1 is an option but I want to make sure it's not before I buy a KVM. Is it possible to enter the passphrase remotely? AND is it a good idea?
