• xmonad + urxvt issue: text disappears after resizing

  - by user1212010

  I'm using Arch Linux + xmonad + urxvt bundle and trying to resolve the conflict between xmonad and urxvt. Better to explain with shots: Firstly, open the terminal and get some full-length output. Secondly, create another window, which squeezes the first. And, finally, close it to find out that half of the output disappeared. Sometimes it behaves correctly, sometimes not. Tried to find out why, but failed. Many thx in advance!

• Unable to view users and groups

  - by Ewr Xcerq

  I am using Centos5 running on a VMWare but whenever I choose to open the User Manager menu from System-Administration, an error message always displays The user database cannot be read. This problem is most likely caused by a mismatch between etc/passwd and /etc/shadow or /etc/group and /etc/gshadow/. The program will now exit. I am a Linux novice and have no idea how to fix this tiny issue. ANy help is thankful. Thank you.

• Canonical configuration for multiple-instance Postfix?

  - by threecheeseopera

  I recently attempted to reconfigure an existing single-instance Postfix server (multi-homed) to support multiple MTA instances, but failed miserably (read: open relay, nastygram from ISP). It appears that there are several methods that can be used to accomplish this, and the various (and numerous) secondary sources that I found online were 'all over the map' with respect to which they used/glued together. Can anyone provide a working configuration (or tips) that use postmulti to manage a multi-instance Postfix setup?

• How to measure TCP connection time in Linux

  - by Paul Draper

  I want to measure the overhead in creating a TCP connection. I know of many tools like hping and netperf, but they seem oriented at measuring latency. I want to know how long the 3-way handshake takes, and allocating any buffers, etc., and then closing it. So I want to open a real, legitimate TCP connection, and then close it. Are there any tools that will do that and help me measure performance?

• Better way to quad+ boot operating systems?

  - by Wijagels

  I currently have Windows 7, Ubuntu 12.04, Fedora 17, and open SUSE installed. I currently use BURG boot loader to load up all the systems. However, BURG does not work with windows(I still manage) and it is a little finicky. So, I want to make windows work and have all the other OSes I want all on one boot loader. I already tried easy BCD and for whatever reason Fedora took over and blocked out the other OSes.

• How to map PageDown and PageUp Keys to function normally

  - by mtk

  When I open a document using vi or vim, I am unable to navigate the page using Page Up and Page Down keys. On pressing these keys, vim seems to behave in abnormal maaner, and changes the case of character beneath the cursor. It then takes few seconds to come back again in insert mode. Please let me know, how to map these keys, so that on pressing them I can scroll through pages smoothly just like Ctrl+ (f / b / u / d ).

• Install Visual Studio 2010 on SSD drive, or HDD for better performance?

  - by Steve

  I'm going to be installing Visual Studio 2010. I already have my source code on the SSD. For best performance, especially time to open the solution and compiling time, would it be better to install VS 2010 on the SSD or install it on the HDD. If both were on the SSD, loading the VS 2010 files would be quicker, but there would be contention between loading the source and the program files. Thanks!

• Copying info from the device manager to the clipboard

  - by user12816

  I have a Logitech webcam, which I can plug into my Windows XP machine via USB. When I open the Device Manager, I can select the webcam and choose Properties--Driver--Driver Details. This gives me the following list of driver filenames: C:\Program Files\Common Files\logishrd\WUApp32.exe [25 more filenames...] C:\WINDOWS\TWAIN_32\QuickCam\reset.wav My question is, is there any way to copy this list to the clipboard? Copying it by hand is a drag.

• How do I install Skype on computer so that anyone who logs in does NOT have to go through the initial config?

  - by Matt

  I installed Skype when logged on to the (local) admin account. Now, when I log off that, and log on as myname on the domain, I have to click through the intial setup steps (after you've already run the installer) of Skype. So, I have to click next to get through the mic setup/test, and it asks me if I want to take a pic. How do I get it so that any person who logs in can just open Skype and go straight to the login screen? Windows 7 64 bit, 2008R2

• How do I minimize Evolution to the system tray in Ubuntu?

  - by Jephir

  In Ubuntu some applications can be set to minimize instead of exit on close. For example, Empathy minimizes to the system tray (mail icon) when the close button is pressed in the application window. How do I make Evolution do this as well? Essentially I would like to have Evolution hidden in the system tray instead of having to re-launch it every ten minutes to check for new messages (or leave it open and clutter the taskbar).

• Full File Path in Reference to Another Workbook in Excel

  - by SHARIQ MUSANI

  I have two Excel files, one on D:\ and the other one on E:\. I reference one from the other, for example, using vlookup in the E: file to search from the D: file, like that: VLOOKUP(A1,'D:\SHARIQ\[FILE NAME.XLS]SHEETNAME'!A1:10,3,FALSE) As long as D:\SHARIQ\FILE NAME.XLS is open, I get the formula in the E: file displayed like this: VLOOKUP(A1,'[FILE NAME.XLS]SHEETNAME'!A1:10,3,FALSE) Why does it remove the whole path?

• Typing in web forms lagging - output very slow!

  - by intransit

  Hi all, Just recently, typing in forms on the internet has become rediculously slow. I'm on an oldish PC with low memory (1gb) and amd athlon XP 2800+ (2.08 ghz) and get an awesome 1.0 rating from windows :) Thing is though - it only just started happening. Was fine last week. Also, It doesn't only happen when heaps of other processes are open/running. I can have only one IE window up, after fresh reboot, and still happens. Any ideas why?

• Unix bidirectional pipe on commandline

  - by John W

  I've been able to use this linux command to connect Netcat to a serial port: nc -l 80 <> /dev/ttyS0 I would like to be able to log this transaction. My backup plan is to use Wireshark to monitor the netcat stream, but ideally I'd like to do something like this: cat /dev/ttyS0 | tee upstream.bin | nc -l 80| tee downstream.bin | /dev/ttyS0 This tries to open ttyS0 twice and therefore throws a permissions error. Does anyone know a smarter way to do this?
