• How much RAM on a windows VPS (2003, 2008, 2008R2)

  - by Pietro

  Right now I'm running Windows Server 2003 on a VPS with 640mb RAM and it works fine. I would like to upgrade OS to Windows Web Server 2008 or Windows Web Server 2008 R2. I understand that it is difficult to say how much RAM is needed, but can you make a comparison between 2003 and the two new 2008 versions? RAM on VPS is by far the most expensive item, so I wonder if I can get similar performances with 1GB and 2008 or 2008R2 compared to 640MB and 2003. Basically I run IIS, SQL Server and MailEnable.

• Lightweight window manager for Linux for Virtual Desktop / Multimon

  - by mattcodes

  Previous used Ubuntu Gnome with Compiz but for my basic spec intel macbook (4 years old) its a little too heavyweight.

• How to start Ubuntu with no working video card?

  - by ViliusK

  I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?

• Why are "Inverted Colors" considered an accessibility feature? [migrated]

  - by RLH

  Why is it that in Apple software (OS X and iOS,) the "Inverted Colors" display feature is considered an accessibility option? I understand that some users are color-blind. This would justify the Black & White, or grey-scale modes. What I don't understand is how or why does inverting the display color help someone with any specific, visual impairment or dysfunction. As a programmer that wants to understand the need so that I can develop better, accessible software, what purpose does this feature serve to the end user who has some form of visual impairment? NOTE: I felt that this was a hard question to categorize on StackExchange. I settled here on Programmers because I assume that questions of accessibility are important to all developers and this question sits somewhere in the middle between topics that StackOverflow and SuperUser may cover. Also, this question isn't specific to Apple software. I've just noticed that this feature has been available on Macs for a very long time, it's a feature on iOS, and it's always associated with the Accessibility settings. If I can garner some information regarding the needs of some users, I think that I can develop better, accessible software.

• Computers displaying an unwanted password change prompt

  - by evesirim

  We run a small network of users from a central SBS 2008 server that handles group policy & AD. Most of our users operate under a policy that propts them for a password change every 6 months as a security measure, with a few administrator accounts & terminal machines not using the policy for the sake of ease as they are needed all the time. Recently all machines regardless of policy have started asking for a password change out of schedule. Some PCs run Windows 7 & some XP, though the password prompts don't seem to discriminate between OS. What could this be down to? Many thanks

• In linux: how to exit a program but not kill it?

  - by biomed

  I use Ubuntu 10.10 and I have a python program (mnemosyne) that I synchronize the data files using dropbox. If I forget to close (exit) this program. Here is my problem scenario. I leave the program running at home and go to work but if I open the program at work and work on it the data file is changed and I loose my progress at home when I exit (it automatically saves) when exitimg. I thought I could create a cron job to automatically close mnemosyne every morning regardless os me remembering to do it or not but if I use kill the program exits without saving the datafile and I end up with a tmp file and an error message when I restart it. Is there a better way of sending the exit signal to this program emulating me clicking fileexit menu option. Thanks

• Sudden slow read & write speed on all IO

  - by user23392

  I have a custom built rig that has 2 storage drives. for OS: Western Digital 1.0TB HARD DR 64MB for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ] The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device. I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable. Here's my benchmark on the HDD ( read speed - write speed ): And the SSD: Anyone knows what could be the issue?

• page up/down print ~ instead of history search in terminal

  - by Desmond

  I am on a Macbook Pro with mac os x 10.8.2 I have set: page up: \033[5~ page down: \033[6~ in terminal keyboard settings (pressing esc to get \033). My ~/.xinputrc is: # Be 8 bit clean. set input-meta on set output-meta on set convert-meta off # Auto completion options set show-all-if-ambiguous on set completion-ignore-case on # Keybindings "\e[1~": beginning-of-line # Home key "\e[4~": end-of-line # End key "\e[5~": history-search-backward # Page Up "\e[6~": history-search-forward # Page Down "\e[3~": delete-char # Delete key "\e[5C": forward-word # Ctrl+right "\e[5D": backward-word # Ctrl+left I am just following a guide found on internet (actually there are a lot of guide really similar): http://macimproved.wordpress.com/2010/01/04/fix-page-updown-home-end-in-terminal/ Unfortunately, the only (terrific) result is that when I press page up (fn + up arrow) just a "~" is printed in the terminal.

• About C# objects and the possibilties it has

  - by user527825

  As a novice programmer and I always wonder about c# capabilities. I know it is still early to judge that but all i want to know is can c# do complex stuffs or something outside windows OS. I think C# is a proprietary language (I don't know if I said that right) meaning you can't do it outside Visual Studio or Windows. Also you can't create your own controller (called object right?) like you are forced to use these available in toolbox and their properties and methods. Can C# be used with OpenGL API or DirectX API Finally it always bothers me when I think I start doing things in Visual Studio, I know it sounds arrogant to say but sometimes I feel that I don't like to be forced to use something even if its helpful, like I feel (do I have the right to feel?) that I want to do all things by myself? Don't laugh I just feel that this will give me a better understanding. Is Visual C# like using MaxScript inside 3ds max in that C# is exclusive to do Windows and Forms and Components that are Windows related and maxscript is only for 3d editing and manipulation for various things in the software. If it is too difficult for a beginner I hope you don't answer the fourth question as I don't have enough motivation and I want to keep the little I have. Note: Sorry for my English, I am self taught and never used the language with native speakers so expect so errors. I have a lot of questions regarding many things, what is the daily ratio you think for asking (number of questions) that would not bother the admins of the site and the members here. Thank you for your time.

• Why does Windows Media Center try to open zip files?

  - by gpryatel

  Notes: OS is windows 7, browser is latest firefox. After saving a zip file to the desktop, Windows Media Center opens up. I looked around its config settings but could not find anything related to zip files. How do I turn that off? Also, don't know if this should be a separate question or not: Unless I right click save link as... for zip files, I don't get a firefox dialogue asking what to do with the file (Open/Save). The files get saved to some place like c:\users\namegoeshere\appdata This only happens on the win7 computer. I looked around in firefox's settings for saving files, and I do have 'ask me where to download...' enabled. I can get more exact path names when I get home.

• Setting up Mac VPN on simple network with separate IPs

  - by Dave

  Hi there, We have a pretty simple network configuration. A typical ASDL line with two extra IP addresses. We have a basic home network router Dlink DIR-655. We have two Mac OS X Snow Leopard Servers that we want to setup VPN on. The problem is that we can't change the ports which VPN works under ie. we can only setup port forwarding for UDP 500,1701,4500 to a single server. I'm wondering how we can cost effectively re-work our network so that we can take advantage of the separate IP addresses and have both VPNs working with the same router. Is that possible with our current hardware setup or do we need something more powerful? We're also toying with Mobile Access and wondering if that might be easier to setup. Expert help is greatly appreciated.

• XenServer 5.6.1-fp1. Can't get network working

  - by casey_miller

  I have a PC where XenServer 5.6.1 fp-1 has been successfully installed. I've manually set the network settings: 192.168.1.50 255.255.255.0 192.168.1.1 but it's set to xenbr0 iface. While eth0 is empty. When I click on "Configure Management Inteface" it shows that eth0 is connected. But when I ping a default gateway (which is 100% should be accessible) it fails. I used to another shell (Alt+F3) and logged as root. I also failed to ping. with both: ping -I eth0 192.168.1.1 and ping -I xenbr0 192.168.1.1 Be assured that: Cable works Ethernet adapter is 100% functional (prev OS was Ubuntu it was working) There is no firewall rule to deny anything. (everything is allowed) So the question is: What is a problem???

• How to create a Windows 7 installation usb from Linux or Mac?

  - by Shane

  I have a Windows 7 installation DVD that came with a computer with no optical drive. I have an empty USB thumb drive. I have access to two computers with optical drives, one running Linux and the other running Mac OS X. Notably, I do not have access to any Windows computer at this time. With the tools that I have, how can I create a thumb drive that I can boot with and install Windows 7? Do I have to look out for anything when making the ISO from the DVD (DRM or anything)? After the ISO is made, will UNetbootin work? How about dd?

• tmux -- any way to enable scrolling, but not selection?

  - by gatoatigrado

  I like that when mode-mouse is on in tmux, I can scroll through the buffer, but I don't like that I can't copy stuff to my OS clipboard by selecting it (as when tmux is disabled). Question: Is there any way to enable mouse scrolling, but not selection? I'm using KDE's konsole, if it matters. I've tried setting, set -g mouse-select-pane off set -g mouse-select-window off but no luck -- the only difference seems to be whether mode-mouse is on (tmux captures scrolling and selection) or off (tmux captures neither scrolling nor selection).

• Numpad's Enter key is acting like the Command key instead

  - by user19294

  I can't get the numpad Enter key to work on OS X 10.6.5. The numpad works fine, as do the plus and minus keys. Only the Enter is not working. I tried 2 keyboards and I get the same problem with both, so it's got to be a setting somewhere. In Keyboard Viewer, when I press the key, it shows that the ? keys are pressed. And indeed, pressing Enter-L puts the cursor in the location bar of my browser, just like Command-L would. Is there a way to remap it?

• Windows 7 RC sleep on Thinkpad R51?

  - by Ragesh

  I have an old Thinkpad R51 and Windows 7 just doesn't give me a Sleep option. I suspect it's because it's running the default VGA driver. The machine has an Intel 855 GME graphics adapter but there doesn't seem to be a WDDM driver available publicly. Lenovo's driver download page just says that drivers for Vista are bundled with the OS. Apparently, they aren't bundled with Windows 7 as it always defaults to a generic VGA driver. Is there a reliable way to get Sleep to work on this machine?

• root directory - www or public_html

  - by Phil Jackson

  Is the root directory where all files are kept (directly from accessing from FTP) always "www" or "public_html" depending on what OS? Or is it possible to rename this folder? And if so, what would be unique about this folder to be able to identify it? i.e. currently I just wrote this; my $root; my $ftp = Net::FTP->new($DB_ftpserver, Debug => 0) or die "Cannot connect to some.host.name: $@"; $ftp->login($DB_ftpuser, $DB_ftppass) or die "Cannot login ", $ftp->message; my @list = $ftp->dir; if( scalar @list != 0 ) { foreach( @list ){ if( $_ =~ m/www$/g ){ $root = "www"; last; }elsif( $_ =~ m/public_html$/g ){ $root = "public_html"; last; } } } but would not work if it has a different name. Any help much appreciated.

• something like persistent X forwarding?

  - by Arthur Ulfeldt

  I'm having trouble with the title on this one, please edit. When users connect to a VM with VNC/NX/RDP/other-tla they get a persistent desktop in a window . When they connect using ssh -X forwarding they get a local window managed by the local windo-manager that is not persistent. 1: is there a way to run a program on the VM and have it managed locally AND have it persistent? 2: can the client be on windows or OS-X? ps: in this case the vm's are running Ubuntu

• Migrate to SSD - NTFS mount point for Program Files

  - by Icode4food

  Here is my thought. I have a new computer that I just built and am considering migrating to a SSD. I have Windows all setup and my Development environment configured so I want to avoid having to re-install a bunch of stuff. My thought is to clone my OS (win7) to the SSD and then mount a HDD partion to C:\Program Files (x86)\ with C being my SSD. This way as far as the programs are concerned they still live on the C drive but in reality they are physically located on the HDD. This seems to me like a good idea but after searching around a bit and not having found anyone else that had the same idea, I'm wondering why not. Maybe I am missing something that is obvious to everyone but me. Why is this a good or a bad idea?

• raid advice with SSD and two HDD

  - by Nin

  I have a new machine with one 128GB SSD and two 1TB HDD. On the SSD is the OS and my initial thought was to put the two HDD in RAID 1 for user data. After some more thought I came up with two other setups and now I'm in doubt :) Can someone advise what would be the best setup? 1: single SSD and HDD in RAID 1 (original thought) 2: Create 2 partitions on the HDD (128GB and 872GB). Put the two 872GB in RAID 1 and create another RAID 1 with the SSD and one 128GB HDD partition. 3: Create 2 partitions on the HDD (750/250), put the 705GB in RAID 1 and use the 2 250GB as backup and make automatic snapshots of the SSD to (one of) these partitions. I think the 2 main questions are: Is it advisable to create a raid array with only part of a drive and actively use the other part of that drive or should you always use the full disk? Is it advisable to create a raid 1 array with a SSD and HDD or will that blow the whole speed advantage of the SSD?

• Will Windows 7 setup overwrite Windows 8 and Ubuntu boot records?

  - by Jens

  I have Windows 8 and Ubuntu installed, both an the same physical hd (2 partitions). Windows 8 was installed after a format, Ubuntu afterwards. I used EasyBCD to setup the boot records and the boot menu order. I want to install Windows 7 as a third operating system and just add its boot record with EasyBCD. Will there be any unwanted behavior when I install it on a third partition? I already have 100 GB of unallocated space on the disk, though have not yet made the partition. I red on this site that I should install the oldest OS first, but than I would have to do a format and start again from scratch (which I clearly do not want to do). edit: On this site, the opposite is claimed, saying it's also possible to install Windows 7 after Windows 8. However, it will restore a Windows 7 boot menu instead one of Windows 8.
