  • We are moving to two servers from one server due to performance issues. How do we monitor the value of this change?

    - by MikeN
    We are moving to two servers from one server due to performance issues. We are moving our MySQL DB to its own dedicated server and will keep the original machine as the front end machine running nginx/apache (Django backend.) How do we monitor the value of this change? It is possible our whole site could actually get slower since the MySQL queries will be going out over a secure remote connection instead of locally?

  • What OS for Eee PC ?

    - by crivateos
    Hello. I've just bought new Eee PC 1005 (with Atom N450, 250GB and 2GB memory) without any pre-installed system. Now I'd like to install windows and linux distribution on in. What should I choose ? I am a programmer and web designer, so I need Java IDE , Python interpreters, and Photoshop (on windows). Will Win 7 Pro 32bit work ?Or should I choose Windows XP ? And what about linux distro ? Ubuntu, Eeebuntu, Ubuntu netbook edition ? btw is it true that linux's grub overrides mbr so that hardware system restore doesn't work ?

  • how to recover data from my disk - I accidentally copied with dd an iso on it

    - by sijoune
    I wanted to create a bootable usb from an iso image and i accidentally put as the output of the dd, instead of my usb drive, one of my hard disks. The iso was 3,3 GB and my disk is 1TB! And it was almost full. Can i at least restore the data that has not been overwritten? Right now i can't even mount it. I get this error: Error mounting /dev/sdd1 at /media/main/UDF Volume: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sdd1" "/media/main/UDF Volume"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdd1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Also since i know which filesystem my disk used if i reformat it to this filesystem is there any chance i can mount it and retrieve the rest of the files?

  • Why is my PC boot time slow when USB HDD attached?

    - by John
    I have a USB Hard disk that I am using as a secondary drive just for extra storage. When this is attached and I start my PC the second screen says searching for mass storage dives for about 5 minutes before continuing on. The same happens when I have a USB pen disk attached upon boot. If I attach the device after the PC has loaded then it is very quick however plugging and unplugging is not ideal. Is there away to disable this in the BIOS as I cannot instantly see an option. On boot it informs me I have an American Trends AMIBIOS in the BIOS setup it states the version as v02.58 2006. This is running on a ASUS MV2 Motherboard.

  • How do I stop Mac OS X Snow Leopard from losing the keyboard shortcuts I create in System Preferences?

    - by Philip
    I can't explain it. In OS X 10.6.6 (but also in previous versions; nothing to do w/ latest update), I create some keyboard shortcuts both for individual applications and for "all applications." I use them for a while. Later, sometimes after restart sometimes not, they're gone. Where'd they go?!?! (More importantly, how do I make them stop disappearing? Less ideal solution: how do I back them up and quickly restore them?) Thanks!

  • How to recover the data from the crashed (external) hard disk drive (NTFS)?

    - by shveerab
    The 300 GB harddisk has 2 partitions,90 GB and 200 GB! I can see the drives in windows(XP) but unable to access them, the file system is shown as RAW, 0 used space and 0 free space!..chkdsk returns the error "unable to determine volume version and date. chkddsk aborted." Is the MBR corrupt? How do I restore it? TestDisk tool isn't recognizing the partitions and says invalid entry for heads/cylinder, 15 and should be 255 and suggests to change it..Should I go ahead and change it? Please advise!

  • How do I find out when and by whom a particular user was deleted in linux?

    - by executor21
    I've recently ran into a very odd occurrence on one system I'm using. For no apparent reason, my user account was deleted, although the home directory is still there. I have root access, so I can restore the account, but first, I want to know how this happened, and exactly when. Inspecting the root's .bash_history file and the "last" command gave nothing, and I'm (well, was) the only sudoer on the system. How would I know when this deletion happened? The distro is CentOS release 5.4 (Final), if that helps.

  • Problem accessing MICROSOFT##SSEE database (Error: 18456, Severity: 14, State: 16.)

    - by Philipp Schmid
    After an unexpected server shutdown due to a power failure, I can no longer connect to the internal windows database MICROSOFT##SSEE which is hosting Central Admin for my SBS 2008 server. The log shows: Error: 18456, Severity: 14, State: 16. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. [CLIENT: <named pipe>] I've tried to connect using the SQL Management studio (connecting to .pipemssql$microsoft##sseesqlquery) but no luck. The SQL Server Configuration Manager doesn't show a entry for 'Protocols for MICROSOFT##SSEE' (but shows it for 2 other database hosted on the same SQL server 2005 Express edition. I have tried to restore the master.ldf and mastlog.log files from a backup, but the issue persists.

  • DNS Setting keeps changing on me

    - by Chiggins
    So on my Windows Server 2008 box, I have a DNS server installed on it. For some reason, every ten minutes or so, the Host (A) address for the computer keeps on changing to its internal private IP address. I want it to have its public address for Active Directory purposes, but it keeps changing itself back to the private IP address. Any idea as to why, and how to change it? If it makes a difference, this is an Amazon EC2 server. Thanks

  • Can files deleted on an ecnrypted drive be restored?

    - by roddik
    Hi. There are ways to restore files, deleted from the system by default, I'm not sure about the way they work but I guess thet read content, that has not been overwritten. On the other hand, there are programs (e.g. TrueCrypt), that encrypt disks, claiming that it wouldn't be possible to tell apart random data and file contents on such a disk without a password. Therefore I think that files, deleted from such disks can't be restored. Is that correct? I know one way to find out would be to try it, but there is a possibility, that I would just pick the wrong restoring software. Moreover, I'm more interested in theorethical explanation why it would/wouldn't be possible. Thanks

  • What is the bitrate of itunes streaming

    - by The Journeyman geek
    I've been using itunes streaming (in part cause its easy) to access my music collection between two windows PCs. I'm half certain it sounds kinda 'flat' so i'm wondering, what bitrate it uses, and format - it sounds fine off a PMP, and even better on a PC, so i assume i can tell the difference.

  • Make a temp network.

    - by giodamelio
    I have a XAMPP test server running on my Windows Vista laptop. I also have a small wireless router. I would like be able to create a small temp network that could broadcast that network so any other computers connected to the wifi can go to localhost/ or an internal ip address and view my server. The router will not be able to be connected to the internet, but I don't see how that would make a difference Thanks giodamelio

  • Windows XP alt-tab: How to restrict options to certain applications, in certain order and exclude others?

    - by Rob
    In Windows XP Alt-tab keypress sequence to select applications, how can I ensure that certain applications always appear, in a certain order, with others always excluded? Background for asking is that most XP-based machines that I am working with on a shop floor present the list of shortcuts in a certain order and certain applications. There is one machine however, that displays an additional application. This is a hindrance to the users of the machines, as the nature of their work is routine and this variation disrupts the remembered sequence, "disrupts their flow". Thoughts? Being a good superuser, I research first before asking, and I found: Applications randomly alt-tab? (especially full screen games) Restore Alt-Tab behavior so that minimizing an app once again moves it to the end? (2. looks close to the control I need, but would need more finer, preciser control over what appears in the selection). Suggestions? (Thanks in advance.)

  • Would it be better to have 10 GB PC5300 or 8 GB PC6400?

    - by jayrdub
    My development machine is heavy on memory usage. It currently only has 4GB of PC5300. I'm going to buy 8 GB of RAM, but should I take out all my existing memory and install just PC6400 or leave some of the original and stick with 5300? I don't know if I'll ever need more than 8GB, I might, I'm just wondering if the speed difference between 5300 and 6400 is worth trashing the 2 or 3 GB of old RAM I would still have room for after adding the new RAM.

I have Internet access through a wireless modem/router (2 Mbps DSL connection, wireless reception is excellent). I use Opera and when I turn on Opera turbo the same sites download fully. I tried changing to some other dns (opendns, google dns), but it made no difference. What would you suggest I try? OS : Windows 7 64 bit

  • ubuntu 9.10 on an external usb drive: grub1 does not work

    - by Toc
    I have installed Ubuntu on a partition of my external usb drive. Since I had problems with grub2, I have uninstalled it and installed grub1. But then the usb drive didn't boot anymore, and I am forced to the limited shell of grub1. If I write manually kernel (hd0,4)/vmlinuz-2.6.31-15-generic root=/dev/sdb4 ro quiet splash initrd (hd0,4)/boot/initrd.img-2.6.31-15-generic boot then Ubuntu is loaded, but if I execute the commands root (hd0,4) setup (hd0) as explained at http://www.gnu.org/software/grub/manual/html_node/Installing-GRUB-natively.html#Installing-GRUB-natively, next time I boot from usb I am forced again to the grub limited shell. How can I restore a working grub?
