Create a gPXE bootable USB drive

gPXE is an open source network bootloader which I have been using to boot of iSCSI targets.

In order to get gPXE onto a bootable USB drive you must first create a custom image using their ROM-o-matic. Here you can choose the appropriate NIC and add additional options or an embedded script that will run automatically. You will want to choose “USB Keychain disk image (.usb)’ as the output format.

Rename the downloaded gpxe-xxxx.usb to gpxe-xxxx.img

Then download and run Win32DiskImager and point the application to gpxe-xxxx.img

Chose the device that corresponds to your USB flash drive and press ‘Write’.

Now all you have to do is plug the USB drive into the destination and boot from the USB device.

Switching from Remember the Milk to Producteev with Astrid

A couple of days ago the popular Android tasks application, Astrid, announced that they will no longer be able to provide task syncing with Remember the Milk. Astrid did however give users the option of running an older version of Astrid or a version with certain features disabled (these features violated RTMs ToS and are the reason for this announcement). Additionally, Astrid will work with Producteev and Google Tasks.

I have chosen to jump ship from RTM and try out Producteev which seems to have many of the same features as RTM and the ones that GTasks lack, such as tagging. I was wondering how I was going to get all my tasks/assignments in the middle of the semester over to this new service, but figured I would just try syncing all my information into Producteev with Astrid and cross my fingers.

I signed up for a Producteev account and opened up Astrid on my Droid. I typed in my new credentials under the sync settings for Producteev and a sync began. I opened up the Producteev website and my tasks were immediately popping up, one at a time. To finish up, within Astrid I logged out of RTM sync.

In just a few minutes all my tasks had been accurately moved from RTM to Producteev using Astrid and now I can continue syncing my tasks from my phone to the cloud for safe keeping and easy editing while staying with the most up to date version of Astrid for my phone.

Test Read/Write speed in FreeNAS

Navigate using the ‘cd’ command into your zpool which is in the /mnt directory.

Run the following command to test Write speed
# dd if=/dev/zero of=testfile bs=1024 count=50000

Run the following command to test Read speed
# dd if=testfile of=/dev/zero bs=1024 count=50000

The first test will write a file called ‘testfile’ to your zpool and then the second test will read back that same file. You can change the count in order to change how large a file to create.
