Online File Sharing

I was needing a way to share a few large files with some different individuals and decided to search for free and easy to use online file sharing.

Microsoft has Windows Live Sky Drive. http://skydrive.live.com/

MediaFire “File Hosting Made Simple”. http://www.mediafire.com/

Currently I think Sky Drive requires all parties to have a Windows Live ID, but MediaFire does not. I was able to create the account and share the folder with multiple people using a customized URL. They were not required to create a MediaFire account just to access the files I had made available.

Speed up Revit FBX Renderings in Max Design

A simple change in the DesignVIZ options can vastly improve mental ray Pre-Processing when rendering scenes imported from Revit FBX files.
In Notepad, open the file "CurrentDefaults.ini in your local User's files (typically at C:\Users\YourUserName\AppData\Local\Autodesk\3dsMaxDesign\2010 - 32bit\enu\defaults\DesignVIZ.mentalray\CurrentDefaults.ini").
Search for the parameter 'DontRepeatRefMsg' and change it's value from 0 to 1.
Four lines down is the parameter 'InvalidateTMOptimization' and change it's parameter from 0 to 1. You should now have:
DontRepeatRefMsg=1
; comment comment comment...
; comment comment comment...
; comment comment comment...
InvalidateTMOptimization=1
Pre-Processing at the start of mental ray rendering should now happen in a few seconds instead of minutes.
You have to restart Max to accept the change. You should also edit the DesignVIZ.mentalray preset at your program installation folder, usually "C:\Program Files\Autodesk\3ds Max Design 2010\Defaults\DesignVIZ.mentalray\FactoryDefaults\CurrentDefaults.ini"
Be sure to do the editing for both x32 and x64 if you have both installed. Editing the INI file in the Max installation folder prevents a change if you choose an option from the "Customize>Custom UI and Defaults Switcher".

Enable the Administrator Account In Vista Home Premium

1. Go To Start > Accessories > Command Prompt
   Right-click on the icon “Command Prompt” and choose “Run-As Administrator”

      (this will enable the administrator account)
   2. net user administrator /active:no
      (this will disable the administrator account)
   3. net user administrator password

      (in this example “password” is the password)
   4. net user
      (this will list all the user accounts on the system)

Vista Home – Net Account

I stumbled on how to accomplish changing the password expire settings in Vista Home Premium.

To remove the password expire date in Vista Home Premium, you have to use the old command line and use the net command to do this. I looked all over the GUI account dialog box for an option to to this but could not find one.

So to lift the password expire day do this.

 

1. Under Start>Accessories> “Right-Click” on Command Prompt and click on “Run As Administrator”
2. This will open a dos dialog box. At the prompt type in
1. net accounts (this will list out all the settings for the current user)
2. net accounts ? (this will list the syntax for using the command)
3. net accounts /maxpwage:unlimited (this syntax will remove the password expiration date)
4. net accounts /maxpwage:100 (this will set the password to expire in 100 days)

FreeBSD with ZFS filesystem

My notes to remember different zfs commands.

The FreeBSD Handbook is a good starting place.

or

The OpenSolaris.org website.

zpool create zfsstorage /dev/ad0

zfs create zfsstorage/compressed

zfs set compression=on zfsstorage/compressed

zfs set compression=gzip-4 zfsstorage/compressed

zfs list

zfs set sharenfs="-maproot=root -network 10.1.41.0" zfsstorage/compressed

zfs get compressratio zfsstorage/compressed

zs get all

Using Ubuntu as a backup server

1. Install Ubuntu 8.04 LTS with a minimal install
2. Use apt-get update to update the repositories
3. Use apt-get upgrade to make your new server current with security patches
4. Use apt-get install rsnapshot, rsnapshot will be the backup technique we will use
5. Configure your raid volume where your backups will be stored
6. I use a hardware raid card, so all I need to do is make the partition.
7. Use fdisk to create the partition.
   fdisk /dev/sdb
8. I use jfs for my backup storage filesystem
9. Use mkfs.jfs –L raid5 /dev/sdb1
10. Add the new partition to /etc/fstab
    LABEL=raid5     /mnt/raid5      jfs     rw,atime        0    0
    If you want you can use blkid to get the UUID of the new partition and use UUID instead of LABEL in /etc/fstab
11. If you try to mount the partition, you will probably get an error relating to there is not a /dev/ created yet.
12. You now need to run partprobe to create the new /dev
13. Now you can mount the partition
14. mount /mnt/raid5
15. Now we can edit the rsnapshot file located at /etc/rsnapshot.conf
16. Set snapshot_root to be on your newly created partition like below
    snapshot_root   /mnt/raid5/rsnapshot/
17. Skim thru the rest of /etc/rsnapshot.conf and modify as needed.
18. Update here about ssh-keygen –t rsa
19. Update here about sftp id_pub to server 2
20. Update here about server 2 path in /etc/rsnapshot.conf
21. Update here about running rsnapshot daily
22. Update here about adding cron entries
23. Update here about adding a samba share to access the backup from windows.
