WordPress latest version rocks

I have to say that the latest incarnation of WordPress (2.7.1) really does show what a well crafted package can do. I use it for blogging and would absolutely recommend it to anyone who wants a well designed – well laid out and genuinely nice to use piece of web based software. The upgrade process is pretty much bullet proof and allows you to maintain the content you generate whilst upgrading the fabric of the application.

I love the new layout and look forward to whatever the next release brings – Onwards and upwards WordPress !!!

RRRRepeated Characters when TTTTyping in Remote Console

I’ve noticed this several times recently when evaluating new VMs – typically unix based across a wireless link to an ESX 3.5 server.

If you are using a wide-area or low-bandwidth connection, the time delay over the network may be long enough to cause the virtual machine to start auto-repeat.

To reduce these effects, increase the time threshold necessary for auto-repeat in the remote console.
Power off the virtual machine.

Add a line similar to the following to your virtual machine’s configuration (.vmx) file.

keyboard.typematicMinDelay = “2000000″

The delay is specified in micro-seconds, so the line in the example above increases the repeat time to 2 seconds. This should ensure that you never get auto-repeat unless you intend it.

Power on the virtual machine.

Backup virtual esx machines to usb drive

I noted this while researching a backup question for VMware – useful to know that the esx can talk directly to the usb device !!

so heres the info

Storage USB devices can be used to back up virtual machines. By default, USB devices are supported on ESX 3.x. The USB drivers are pre-loaded in ESX 3.5.

The following filesystems are supported:
FAT32 read/write.
ext3 read/write
NTFS read only

To copy data from Service Console to a USB device:
Plug in the storage USB device

Run the following command to determine which device name the kernel assigned to it:

tail /var/log/dmesg

Run the following command to create a mount point:

mkdir /mnt/usb

Run the following command to mount the drive:

mount /dev/[device_name] /mnt/usb -t [filesystem_type]

Note:
Replace [device_name] with your device name found in step 2
Replace [filesystem_type] with vfat (FAT32) or ext3

Run the following command to unmount the device:

umount /dev/[device_name]

To export the VMDK (virtual disk):

vmkfstools -i /vmfs/volumes/[datastore_name]/[vm_name]/[vm_name].vmdk /mnt/usb/[vm_name].vmdk -d 2gbsparse

To import the VMDK (virtual disk):

vmkfstools -i /[path_to_USB_mount]/[vm_name].vmdk /vmfs/volumes/[datastore_name]/[vm_name]/[vm_name].vmdk

To copy the configuration files for a virtual machine:

cd /vmfs/volumes/[datastore_name]/[vm_name]
tar -czvf [vm_name].tar.gz *.vmx *.log *.nvram *.vmxf *.vmsd
cp [vm_name].tar.gz /mnt/usb

To extract the configuration files of a virtual machine:

tar -xzvf [vm_name].tar.gz /vmfs/volumes/[datastore_name]/[vm_name]

so there you have it – another little tip for working with your vmware ESX server and Vms….
