CloudTrax, the free online Mesh wifi networking platform, has undergone a major update. CloudTrax 4 introduces several improvements and new features:

To disable automatic suspend, but leave manual suspend working in Ubuntu 14.04, create the text file:
[Disable suspend (upower)] Identity=unix-user:* Action=org.freedesktop.upower.suspend ResultActive=no ResultInactive=no ResultAny=no [Disable suspend (logind)] Identity=unix-user:* Action=org.freedesktop.login1.suspend ResultActive=yes ResultInactive=no ResultAny=yes [Disable suspend when others are logged in (logind)] Identity=unix-user:* Action=org.freedesktop.login1.suspend-multiple-sessions ResultActive=yes ResultInactive=no ResultAny=yes
Backups with HP Data Protector may fail with the following error:
First, attempt to perform a manual clean of the drive, then try re-running the backup. If it fails again, power-cycle/reboot the drive/library.
If the error still persists, start HP Library and Tape Tools and run a drive assessment. You'll need to load a tape into the drive first. If the test fails (i.e. it returns an error code, such as internal error), call HP for support.
A quick (minor) bug fix on the site just before going to vacation: the search and login boxes now maintain the proper size in Google Chrome so the submit button images behind them no longer shift to below them.

When restoring a database, you usually start with restoring a full backup, then any differentials, and finally the transaction logs. You set the database restore mode to WITH NORECOVERY, which allows you to perform these additional restores.
But what if you find out that there's nothing more to restore, leaving you with a database stuck in Restoring mode? Then you only need to run a single T-SQL statement:
RESTORE DATABASE [db_name] WITH RECOVERY
Replace db_name with the name of your database.

No_Light means there's no link on the port. Usually this indicates a problem with the physical wiring, either a faulty cable, or the TX/RX have been swapped.
No_Sync means there's a link on the port (so technically, wiring is okay), but there's a problem with the actual communication. The most common problem is a mismatch in speed on the switch port and the HBA on the other side. Your best bet would be to set the port's speed (temporarily) to auto-negotiate and see what speed is selected. If this does not work, try manually setting the port fixed to lower speeds.
RFC1918 states the following blocks of IPv4 addresses that can be used in a Local Area Network. These are "private" address ranges that do not overlap with public IP addresses.
|Network/mask||Class||First usable addr.||Last usable addr.|
|172.16.0.0/12||Class B (x16)||172.16.0.1||172.31.255.254|
|192.168.0.0||Class C (x256)||192.168.0.1||192.168.255.254|

Also, if your domain is top-level in the AD forest, configure DC1 to sync with external time sources.
To safely remove a node from a Windows 2003 Fail-Over Cluster, follow these steps:

It may be useful to know whether your Mac has a 32-bit or 64-bit EFI. This can be done by running the following command from an OSX Terminal (can run from the installer or recovery partition):
ioreg -l -p IODeviceTree | grep firmware-abi
This should return something like the following:
|• For 32-bit EFI:||| | "firmware-abi" = <"EFI32">|
|• For 64-bit EFI:||| | "firmware-abi" = <"EFI64">|
