• Windows XP Setup Fails to Recognize USB Floppy after formatting AHCI disk

  - by Strahn

  I am attempting to install Windows XP Professional x64 onto a HP EliteBook 8540w. I have downloaded both the latest Intel Rapid Storage Technology drivers and the Intel Storage Matrix drivers that are listed on HPs website and copied the drivers over to a floppy disk (two separate floppies, one for each version of the drivers.) Booting to my WinXP Pro x64 install CD, I go through the F6 process, load the driver and am able to see my HDD, delete, create and format partitions on it. When I go to continue the install, after checking the disk, the system asks me to enter the disk labeled "Intel Rapid Storage Technology" and press enter to continue. Nothing happens at this point when I press enter. This happens if I use the latest drivers or the older drivers. We have created a slipstreamed install CD using nLite that has the AHCI drivers integrated, which installs fine. However, we have identified a number of issues with the system that I believe are side-effects of using nLite for the slipstreaming and I am attempting to verify that. I have researched this issue and found a few examples of others having the same problem, but no solution. The USB floppy is a Lacie branded floppy, connecting it to a working XP workstation shows it to be the Y-E Data USB floppy drive that is supposedly 100% compatible with XP per MS KB 916196.

• How to customize and reuse a DataGridColumnHeader style?

  - by instcode

  Hi all, I'm trying to customize the column headers of a DataGrid to show sub-column headers as in the following screenshot: I've made a style for 2 sub-column as in the following XAML: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:primitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls.Data" xmlns:sl="clr-namespace:UI" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Class="UI.ColumnHeaderGrid" mc:Ignorable="d"> <UserControl.Resources> <Style x:Key="SplitColumnHeaderStyle" TargetType="primitives:DataGridColumnHeader"> <Setter Property="Foreground" Value="#FF000000"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="IsTabStop" Value="False"/> <Setter Property="SeparatorBrush" Value="#FFC9CACA"/> <Setter Property="Padding" Value="4"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="primitives:DataGridColumnHeader"> <Grid x:Name="Root"> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <Rectangle x:Name="BackgroundRectangle" Fill="#FF1F3B53" Stretch="Fill" Grid.ColumnSpan="2"/> <Rectangle x:Name="BackgroundGradient" Stretch="Fill" Grid.ColumnSpan="2"> <Rectangle.Fill> <LinearGradientBrush EndPoint=".7,1" StartPoint=".7,0"> <GradientStop Color="#FCFFFFFF" Offset="0.015"/> <GradientStop Color="#F7FFFFFF" Offset="0.375"/> <GradientStop Color="#E5FFFFFF" Offset="0.6"/> <GradientStop Color="#D1FFFFFF" Offset="1"/> </LinearGradientBrush> </Rectangle.Fill> </Rectangle> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition Width="1"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Grid.ColumnSpan="3" Text="Headers" TextAlignment="Center"/> <Rectangle Grid.Row="1" Grid.ColumnSpan="3" Fill="{TemplateBinding SeparatorBrush}" Height="1"/> <TextBlock Grid.Row="2" Grid.Column="0" Text="Header 1" TextAlignment="Center"/> <Rectangle Grid.Row="2" Grid.Column="1" Fill="{TemplateBinding SeparatorBrush}" Width="1"/> <TextBlock Grid.Row="2" Grid.Column="2" Text="Header 2" TextAlignment="Center"/> <Path x:Name="SortIcon" Grid.Column="2" Fill="#FF444444" Stretch="Uniform" HorizontalAlignment="Left" Margin="4,0,0,0" VerticalAlignment="Center" Width="8" Opacity="0" RenderTransformOrigin=".5,.5" Data="F1 M -5.215,6.099L 5.215,6.099L 0,0L -5.215,6.099 Z "/> </Grid> <Rectangle x:Name="VerticalSeparator" Fill="{TemplateBinding SeparatorBrush}" VerticalAlignment="Stretch" Width="1" Visibility="{TemplateBinding SeparatorVisibility}" Grid.Column="1"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </UserControl.Resources> <data:DataGrid x:Name="LayoutRoot"> <data:DataGrid.Columns> <data:DataGridTemplateColumn HeaderStyle="{StaticResource SplitColumnHeaderStyle}"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Border Grid.Column="0" BorderBrush="#FFC9CACA" BorderThickness="0,0,0,0"> <TextBlock Grid.Column="0" Text="{Binding GridData.Column1}"/> </Border> <Border Grid.Column="1" BorderBrush="#FFC9CACA" BorderThickness="1,0,0,0"> <TextBlock Grid.Column="0" Text="{Binding GridData.Column2}"/> </Border> </Grid> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns> </data:DataGrid> Now I want to reuse & extend this style to support 2-6 sub-column headers but I don't know if there is a way to do this, like ContentPresenter "overriding": <Style x:Key="SplitColumnHeaderStyle" TargetType="primitives:DataGridColumnHeader"> <Setter property="Template"> <Setter.Value> ... <ContentPresenter Content="{TemplateBinding Content}".../> ... </Setter.Value> </Setter> </Style> <Style x:Key="TwoSubColumnHeaderStyle" BasedOn="SplitColumnHeaderStyle"> <Setter property="Content"> <Setter.Value> <Grid 2x2.../> </Setter.Value> </Setter> </Style> <Style x:Key="ThreeSubColumnHeaderStyle" BasedOn="SplitColumnHeaderStyle"> <Setter property="Content"> <Setter.Value> <Grid 2x3.../> </Setter.Value> </Setter> </Style> Anyway, please help me on these issues: Given the template above, how to support more sub-column headers without having to create new new new new template for each? Assume that the issue above is solved. How could I attach column names outside the styles? I see that some parts, properties & visualization rules in the XAML are just copies from the original Silverlight component's style, i.e. BackgroundGradient, BackgroundRectangle, VisualStateManager... They must be there in order to support default behaviors or effects but... does anyone know how to remove them, but keep all the default behaviors/effects? Please be specific because I'm just getting start with C# & Silverlight. Thanks.

• installing and running google-chrome on an old Ubuntu 7.10 legacy system

  - by 12632

  I am trying to get google-chrome to work on Ubuntu 7.10. I installed it with --force-depends and got it to install, but now when I try to run it, I get this error: /usr/bin/google-chrome: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory Is there a way to still get google-chrome to load even without this dependency satisfied? This is an old system that needs to keep this old 7.10 Ubuntu version and I would like to have google-chrome if possible installed, even if it means no sound or other features that are not compatible.

• network topology including many services

  - by mete

  I know this is yet another question on how to setup network but I hope you are not bored of such questions yet. The site is also an office, so it includes windows dc, windows ad, exchange, sql, file sharing, development app servers and other pcs. In addition to office (internal) things, there are both test and prod environments consisting of a web server-app server-sql stack. There is also ftp service open to public. I consider: dmz1 - web server - exchange edge - ftp dmz2 - app server - sql for app server internal - dc and ad - exchange hub and transport - internal file sharing - sql for internal use - app servers for internal use - pcs public - dmz1, only web, ftp and smtp public - dmz2 not possible public - internal not possible dmz1 - dmz2 is possible from web servers to app servers by using http or ajp dmz1 - internal is only possible for exchange, otherwise not possible dmz2 - internal not possible Does this sound ok ? Any other recommendations ? It will be configured using either MS ISA or Jupiter SSG. Thank you.

• KVM Virtual guest Paused on Reboot

  - by David Hamilton

  I'm running REHL 6 and just installed a Ubuntu Server Guest via KVM set to start at boot. This works correctly and the guest loads, but it loads "paused" and requires that I manually un-pause it.

• Clever recording using AVFoundation

  - by martin

  Hello I am working on my master thesis and I am programming app for iOS using AVFoundation framework. I can make by myself session and attach devices to it and record video with sound. The main problem is that I need continous recording (3hours or longer). After three hours user will stop recording and user will choose time eg. 15 mins (max 30 mins) and only this last 15 mins will be stored to iphone memory. Is it possible to 'cut' video while recording or should I record it eg. in 10 minutes block and then delete old video segments and last two segments connect to one bigger? Will perform these connections (stop recording, start new recording and then connect these two segments) lags in final long video segment? Is there any way to perform this 'clever' recording? Thank you for any ideas.

• Nagios Check_hpjd giving me problems!

  - by Mister IT Guru

  When I run the following [root@host plugins]# ./check_hpjd -H printer1.mydomain.com : Timeout from host printer1.mydomain.com I have Net-snmp installed on my system, I noted that i didn't have net-snmp-utils installed, and then I was able to run [root@host plugins]# snmpwalk -Os -c public -v 1 printer1.mydomain.com system sysDescr.0 = STRING: HP ETHERNET MULTI-ENVIRONMENT sysObjectID.0 = OID: enterprises.11.2.3.9.1 sysUpTimeInstance = Timeticks: (325408663) 37 days, 15:54:46.63 sysContact.0 = STRING: sysName.0 = STRING: printer1 sysLocation.0 = STRING: sysServices.0 = INTEGER: 72 So I know that the printer is working as expected, (as far as SNMP is concerned). But when I run [root@host plugins]# ./check_hpjd -H printer1.mydomain.com -C public Error in packet () I get this error - From what I've tried so far, I know my host can communicate via SNMP, I know the printer responds via SNMP, so I guess I'm left to look at the plug-in, which I will be checking up on. I'm new to SNMP, I am investigating this with my good friend Google search, but I am on a learning curve here, so please forgive my questions if they sound stupid,

• Tools to automate recording streaming radio

  - by Stan

  Is there any tool that can automate recording online streaming radio? I've been use totalrecorder which it has below upside: 1. Handy scheduler. 2. Support create recording templates, so I can customize some high/low quality recording. The downside are it requires to open the streaming radio in browser and can't have another sound source. It's recording what comes out from the speaker. What I am looking for is given a online radio url, and the tool can record the audio stream. No matter if I am playing any other music or not. Thanks.

• Does btrfs balance also defragment files?

  - by pauldoo

  When I run btrfs filesystem balance, does this implicitly defragment files? I could imagine that balance simply reallocates each file extent separately, preserving the existing fragmentation. There is an FAQ entry, 'What does "balance" do?', which is unclear on this point: btrfs filesystem balance is an operation which simply takes all of the data and metadata on the filesystem, and re-writes it in a different place on the disks, passing it through the allocator algorithm on the way. It was originally designed for multi-device filesystems, to spread data more evenly across the devices (i.e. to "balance" their usage). This is particularly useful when adding new devices to a nearly-full filesystem. Due to the way that balance works, it also has some useful side-effects: If there is a lot of allocated but unused data or metadata chunks, a balance may reclaim some of that allocated space. This is the main reason for running a balance on a single-device filesystem. On a filesystem with damaged replication (e.g. a RAID-1 FS with a dead and removed disk), it will force the FS to rebuild the missing copy of the data on one of the currently active devices, restoring the RAID-1 capability of the filesystem.

• Movie colors are off on ubuntu using Movieplayer?

  - by chris

  I've been playing with a new SLR that also happens to record movies. When I try to view a movie using Movie Player, it plays fine, and the sound is there, but the colors are off - green grass is purple, and my golden retriever is a blue retriever. VLC reports that the file is broken, offers to repair it, and plays it with the same problem. The same file plays fine under WinXP with both Media Player and Quicktime, and with no problems under MacOS also with Quicktime. What's the problem, and how can I fix it?

• How do I disable aalert beeps

  - by wheresrhys

  My HP pavilion laptop is getting pretty old and the speakers no longer work properly. So I've disabled all audio devices, including disabling the light-touch volume controls at boot-up. The one sound still here that I can't get rid of is teh alert beep whenever there's an error. It's annoying at the best of times, but when your laptop has no other sounds at all it's intensly irritating! Nothing I chaneg in the windows settings or in the BIOS seems to have any effect. Any ideas how to switch them off?

• Subversion multi checkout post-commit hook?

  - by FLX

  The title must sound strange but I'm trying to achieve the following: SVN repo location: /home/flx/svn/flxdev SVN repo "flxdev" structure: + Project1 ++ files + Project2 + Project3 + Project4 I'm trying to set up a post-commit hook that automatically checks out on the other end when I do a commit. The post-commit doc explicitly lists the following: # POST-COMMIT HOOK # # The post-commit hook is invoked after a commit. Subversion runs # this hook by invoking a program (script, executable, binary, etc.) # named 'post-commit' (for which this file is a template) with the # following ordered arguments: # # [1] REPOS-PATH (the path to this repository) # [2] REV (the number of the revision just committed) So I made the following command to test: REPOS="$1" REV="$2" echo "Updated project $REPOS to $REV" However when I edit files in Project1 for example, this outputs "Updated project /home/flx/svn/flxdev to 1016" I'd like this to be: "Updated project Project1 to 1016" Having this variable allows me to specify to do different actions per project post-commit. How can I specify the project parameter? Thanks! Dennis

• Ubuntu displaying GDM but no login

  - by Shawn

  Ubuntu (Wubi, Lucid Lynx) boots and shows the login screen itself with the background and plays the boot sound but a list of users is never displayed. A mouse is on screen and I can move it but, alas, it does nothing. Dropping to a virtual term with CTRL+Alt+F# drops me to a cursor but I can't actually input anything. I can't boot into single-user with GRUB since it's Wubi and it never specifies a boot kernel directly in GRUB's initial menu.lst (only in files that it then reads from). Other details that may be helpful: Single monitor Same video card that's been working for months No new hardware Edit: I ssh'd in since it evidently booted up the sshd which is handy. dpkg-reconfigure gdm didn't do anything helpful. I do, however, get a "no seat-id found" when manually running it.

I have nothing running in my tray except - Sound control, Laptop power plan indicator,Network status indicator. There are no other processes whose memory usage adds up to so high to make Free memory as 0. Then what could be hogging the memory and make the laptop very slow. Any pointers would help as it is crawling at the moment.

• Unable to force Debian to do unattended install... libc6 wants interactive confirm

  - by JD Long

  I'm trying to create a script that forces a Debian Lenny install to install the latest version of CRAN R. During the install it appears libc6 is upgraded and the install wants interactive confirm that it's OK to restart three services (mysql, exim4, cron). This process HAS to be unattended as it runs on Amazon's Elastic Map Reduce (EMR) machines. But I'm running out of options. Here's a few things I've tried: This previous question appears to be exactly what I'm looking for. So I set up my install script as follows: # set my CRAN repos... yes, I know there's a new convention where to put these. echo "deb http://cran.r-project.org/bin/linux/debian lenny-cran/" | sudo tee -a /etc/apt/sources.list echo "deb-src http://cran.r-project.org/bin/linux/debian lenny-cran/" | sudo tee -a /etc/apt/sources.list # set the dpkg.cfg options per the previous SuperUser question echo "force-confold" | sudo tee -a /etc/dpkg/dpkg.cfg echo "force-confdef" | sudo tee -a /etc/dpkg/dpkg.cfg export DEBIAN_FRONTEND=noninteractive # add key to keyring so it doesn't complain gpg --keyserver pgp.mit.edu --recv-key 381BA480 gpg -a --export 381BA480 > jranke_cran.asc sudo apt-key add jranke_cran.asc sudo apt-get update # install the latest R sudo apt-get install --yes --force-yes r-base But this script hangs with the following request for input: OK, so I tried stopping the services using the following script: sudo /etc/init.d/mysql stop sudo /etc/init.d/exim4 stop sudo /etc/init.d/cron stop sudo apt-get install --yes --force-yes libc6 This does not work and the interactive screen comes back, but this time with only cron listed as the service that must be restarted. So is there a way to make libc6 just restart these services with no user input? Or is there a way to stop cron so it does not cause an interactive prompt? Maybe a creative option I've never thought of? Keep in mind that this system is brought up, some Hadoop code is run, and then it's torn down. So I can put up with side effects and bad behavior that we might not want in a production desktop machine or web server.

• Same netmask or /32 for secondary IP on Linux

  - by derobert

  There appear to be (at least) two ways to add a secondary IP address to an interface on Linux. By secondary, I mean that it'll accept traffic to the IP address, and responses to connections made to that IP will use it as a source, but any traffic the box originates (e.g., an outgoing TCP connection) will not use the secondary address. Both ways start with adding the primary address, e.g., ip addr add 172.16.8.10/24 dev lan. Then I can add the secondary address with either a netmask of /24 (matching the primary) or /32. If I add it with a /24, it gets flagged secondary, so will not be used as the source of outgoing packets, but that leaves a risk of the two addresses being added in the wrong order by mistake. If I add it with /32, wrong order can't happen, but it doesn't get flagged as secondary, and I'm not sure what the bad effects of that may be. So, I'm wondering, which approach is least likely to break? (If it matters, the main service on this machine is MySQL, but it also runs NFSv3. I'm adding a second machine as a warm standby, and hope to switch between them by changing which owns the secondary IP.)

• Proxy Methods for Hosting a Low-Bandwidth Dynamic Website

  - by Casey

  I am building a webcam w/ HTTP server that will be running from a low-bandwith connection. The content on the site will be changing every 5 to 10 minutes. Instead of serving files directly from this connection, are there hosting companies that can act as a public proxy for my site? Therefore, if nobody is using the site, the local internet connection remains idle. And if I receive 1000 hits all at the same time, only one HTTP GET is required, and the hosting company (on a fat pipe) continues serving the other 999 requests? This doesn't sound like a very common usage model, but I feel like this would be the optimal solution to my situation.

• Format Factory not working for mov files

  - by LanguaFlash

  I have attempted multiple destination formats with no success. I am using Format Factor 2.30. I drag and drop a .mov file into FF, select all to mpg (or any format) then click Start. It thinks for a couple seconds and then jumps to 100%. When I open the file I get no sound or picture from the video. These mov files were created with a Canon SX10 camera. (It is my brother's camera so I'm not sure of the model.) Any suggestions? TMPGEnc is able to convert the files with the QTReader plug in so the video isn't corrupted or something. Thanks. Jeff

• Where lies the soul of a computer?

  - by Christian

  When you take the system drive and put it in a new box, do you rename it or do you keep the name? And when you put a fresh drive in the old box, do you give it a new name? What is with upgrading? How many of the components do you have to change until a computer loses its identity? So a CPU is often described as the heart or the brain of a computer but where lies its soul? What determines its identity? The data on the system drive? The majority of its components? This might sound like a not-so-serious question and it probably is but whom of you didn't already face this problem?

My development path is located under the following example path: /home/myusername/myworkspace/hptargetpath/src/pages Considering the following symbolic link mapping: #ls -l /opt/share/www/mydevelopmentrootpath: lrwxrwxrwx 1 root root 77 2011-02-13 18:53 /opt/share/www/mydevelopmentrootpath -> /home/myusername/myworkspace/hptargetpath/src/pages With this folder mapping, I configured Apache HTTPd with the following configuration: <VirtualHost *:*> ServerName local.server.com ServerAdmin [email protected] DirectoryIndex index.html DocumentRoot /opt/share/www/mydevelopmentrootpath <Directory /opt/share/www/mydevelopmentrootpath/ > Options +Indexes Options +FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> But, I'm receiving a 403 Forbidden error when I want to access index.html under the address http://local.server.com/index.html. 403 Forbidden You don't have permission to access /index.html on this server. On httpd debug log, I checked the following message: [Sun Feb 13 19:34:47 2011] [error] [client 127.0.1.1] Symbolic link not allowed or link target not accessible: /opt/share/www/mydevelopmentrootpath I'm thinking that this problem is been generated by some path permission. It's not a direct permission to directory, but some intermediate directory in the path. There's a directive on httpd core Options: SymLinksIfOwnerMatch The server will only follow symbolic links for which the target file or directory is owned by the same user id as the link. But, I tested it without effects. Somebody may help me? I think that it's a trivial configuration on development environment. Best regards, And Past
