SAFARI OS X MAC Corporate Single Sign On using Windows Credentials SSO LDAP Kerberos

Kerberos is built into Mac OS X as well, but isn't as simple to use and configure with Chrome and FireFox as it is with Explorer on a Windows workstation.
You need to do two things before you can use Kerberos for authentication in Chrome/FireFox:

1. Create a Kerberos ticket with the Ticket Viewer application (/System/Library/CoreServices/Ticket Viewer)  
2. OR via the command line (kinit username@example.com, then enter your password). See this article for more detailed instructions.

Research on RPM DROP on AUDI A4 v6 3.0L- Replace PCV valve and Ignition Coil packs

1. interchange spark plugs with the misfiring ones -
   - recheck the code and notice if the misfire codes move to different cylinder
2. Interchange Ignition Coil packs
   - Recheck the scan codes if they change and if it moves to different cylinder
3. A broken PCV valve can also be the reason. (Check the Intake Mainfold Runner Motor)

The most common ones are:

PCV

Intake Manifold Runner Motor

Fuel Pressure Sensor

Might be missing one.

Just had the first two done a few weeks ago, car is driving better than ever!

GSmartControl : GUI for smartctl

GSmartControl is a graphical user interface for Linux smartctl, which is a tool for querying and controlling S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk drives.  You can read about smartctl at : http://unixfoo.blogspot.com/2007/11/disk-information-using-smartctl.html . It allows you to inspect the drive's S.M.A.R.T. data to determine its health, as well as run various tests on it.

GSmartControl features include

• Automatically report and highlight any abnormal SMART information.
• Ability to enable / disable SMART.
• Ability to enable / disable Automatic Offline Data Collection – A short self-check that the drive will perform automatically every four hours with no impact on performance.
• Ability to set global and per-drive options for smartctl.
• Display drive identity, capabilities, attributes, error and self-test logs.
• Perform SMART self-tests.
• Ability to load smartctl output as a "virtual" device, which acts just like a real (read-only) device.
• Works on most smartctl-supported operating systems.

Very hesitantly, I ran xfs_db on the two inodes that xfs_repair complained about. Then ran xfs_repair again, and this time it didn't mention them.... and now I can delete the files I could not delete before...

Hopefully nothing else is missing...

(in my case below instead of mapper/data its md0)

$ xfs_db -x -c 'inode 4497195' -c 'write core.nextents 0' -c 'write core.size 0' /dev/mapper/Data

core.nextents = 0
core.size = 0


$ xfs_db -x -c 'inode 349982619' -c 'write core.nextents 0' -c 'write core.size 0' /dev/mapper/Data

core.nextents = 0
core.size = 0
