Cyber Sprocket Labs started a fun and exciting relationship that is the perfect cross section of two of our favorite things, programming and beer. While we’ve worked on many exciting projects over the years, this is definitely in the top two. None of our esteemed programmers ever thought they’d be working on an application that facilitates the delivery of beer directly to the consumer. Yet, that is exactly what they are doing.
The Table Tap provides a unique and innovate new service to bars and restaurants anywhere in the world. This service puts full service beer taps within the consumer’s reach, literally. A computer controlled interface with up to 4 beer taps is installed directly in the table. A quick swipe of an RFID card activates the taps and allows the customer to pour their own beer, as much or as little as they’d like.
Cyber Sprocket has been instrumental in the helping Jeff Libby bring his concept to the next level. By providing technical support both during and after the installation he has been able to speed up his deployment cycle, increasing revenue. We have also provided extensive programming services to update the business manager, hostess, and system administrator interfaces. During our first few months working on the project we’ve also been tasked with several new additions to the software, the newest of which is enabling direct table-to-table chat using the system’s built in color LCD displays.
Like we said, a very fun and exciting project that has taken our technology services to places we never expected. Thanks Jeff, we look forward to a long and prosperous relationship as your one-of-a-kind solution takes off!

The following has been distilled from https://help.ubuntu.com/10.04/serverguide/C/advanced-installation.html and revised to match our operating process.
Follow the installation steps until you get to the Partition disks step, then:
- Select Manual as the partition method.
- Select the first hard drive, and agree to “Create a new empty partition table on this device?”.
- Repeat this step for the second drive.
- Select the “FREE SPACE” on the first drive then select “Create a new partition”.
- Next, select the Size of the partition. This partition will be the swap partition, and a general rule for swap size is twice that of RAM. Enter the partition size, then choose Primary, then Beginning.
- Select the “Use as:” line at the top. By default this is “Ext4 journaling file system”, change that to “physical volume for RAID” then “Done setting up partition”.
- For the / partition once again select “Free Space” on the first drive then “Create a new partition”.
- Use the rest of the free space on the drive and choose Continue, then Primary.
- As with the swap partition, select the “Use as:” line at the top, changing it to “physical volume for RAID”. Also select the “Bootable flag:” line to change the value to “on”. Then choose “Done setting up partition”.
With the partitions setup the arrays are ready to be configured:
- Back in the main “Partition Disks” page, select “Configure Software RAID” at the top.
- Select “yes” to write the changes to disk.
- Choose “Create MD device”.
- Select “RAID1”
- Enter the number of active devices “2”, or the amount of hard drives you have, for the array. Then select “Continue”.
- Next, enter the number of spare devices “0” by default, then choose “Continue”.
- Choose which partitions to use. Generally they will be sda1, sdb1
- For the swap partition choose sda1 and sdb1. Select “Continue” to go to the next step.
- Repeat steps three through seven for the / partition choosing sda2 and sdb2.
- Once done select “Finish”.
There should now be a list of hard drives and RAID devices. The next step is to format and set the mount point for the RAID devices. Treat the RAID device as a local hard drive, format and mount accordingly.
- Select “#1” under the “RAID1 device #0” partition.
- Choose “Use as:”. Then select “swap area”, then “Done setting up partition”.
- Next, select “#1” under the “RAID1 device #1” partition.
- Choose “Use as:”. Then select “Ext4 journaling file system”.
- Then select the “Mount point” and choose “/ – the root file system”. Change any of the other options as appropriate, then select “Done setting up partition”.
- Finally, select “Finish partitioning and write changes to disk”.
- The installer will then ask if you would like to boot in a degraded state, select Yes.
