Limit Time Machine Disk Usage
as root (size in megs, example 1.5TB):
defaults write com.apple.TimeMachine MaxSize 1500000 (might really be) defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 1500000
to remove quota:
defaults delete com.apple.TimeMachine MaxSize
to speed up TimeMachine:
sudo sysctl debug.lowpri_throttle_enabled=0
OSX Secure swap
sysctl vm.swapusage sudo defaults write /Library/Preferences/com.apple.virtualMemory UseEncryptedSwap -boolean no or: sudo defaults write /Library/Preferences/com.apple.virtualMemory DisableEncryptedSwap -boolean yes reboot

Weblogic Filtering
Login into the console. Click on the Domain Name –> Security –> Filter
You can use the default class : weblogic.security.net.ConnectionFilterImpl
target localAddress localPort action protocolList
Here are the definitions for the parameters of a connection filter rule:
target - specifies the client hosts that the rule must examine. We discuss its syntax later.
localAddress - refers to the server’s host address to which the client connects. If you specify an asterisk (*), this matches all local IP addresses.
localPort - indicates the server port to which the client connects. If you specify an asterisk (*), this matches all available ports.
action - indicates whether the rule should allow or reject the incoming connection request. It can take two possible values: allow or deny.
protocolList - define a space-separated list of protocol names that should be matched. The protocol names can be: http, https, t3, t3s etc. If no protocols are listed, the rule checks for all protocols.
For Example:
www.abc.com 127.0.0.1 7001 deny t3 t3s http https
If you want to deny t3 t3s http https protocol access from www.abc.com to the local server.

Reset Surface 3 Pro
Step 1: Press and hold the power button on your Surface for 30 seconds. Step 2: Press and hold the volume-up button and the power button on your Surface at the same time for at least 15 seconds, and then release both. The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds. Step 3: After you release the buttons, wait 10 seconds. Step 4: Press and release the power button on your Surface to turn it back on.
find
My favorite find:
find . -name "*" -exec grep -i "search term" {} /dev/null \;
You can also exec a rm to get rid of files when a directory has too many entries and "rm *" no longer works.
clone a machine (physical-to-virtual)
Boot using your favorite linux livecd:
# mount a usb drive (example /mnt/usb) # dd sda to file dd if=/dev/sda of=/mnt/usb/sda.dd conv=sync,noerror bs=8192k # move file to VirtualBox host VBoxManage convertdd sda.dd sda.vdi --format VDI # now create a num VM using existing hard drive sda.vdi ...
You can also exec a rm to get rid of files when a directory has too many entries and "rm *" no longer works.

# zpool upgrade
This system is currently running ZFS pool version 8.
All pools are formatted using this version.
# zpool upgrade -v
This system is currently running ZFS pool version 8.
The following versions are supported:

1 Initial ZFS version
2 Ditto blocks (replicated metadata)
3 Hot spares and double parity RAID-Z
4 zpool history
5 Compression using the gzip algorithm
6 pool properties
7 Separate intent log devices
8 Delegated administration
For more information on a particular version, including supported
releases, see:

Where 'N' is the version number.
Display pools format version. The -v flag shows the features supported by the current version. Use the -a flag to upgrade all pools to the latest on-disk version. Pools that are upgraded will no longer be accessible to any systems running older versions.
