The quest to migrate 27TB of data from an old onsite backup server over to an S3 bucket on AWS was an interesting task. I am replacing our old backup server that is connected to an MD3000 power vault array with a virtual machine and a AWS storage gateway. The virtual machine has 18GB of […]

Diagnosing Linux disk space usage

By on February 15, 2015 in Technology with No Comments

The du command with the -kx options is the ideal tool for this job. The k option is for displaying block counts in 1024-byte (1-Kbyte) blocks. I prefer kilobytes because it sorts better than gigabytes. The […]

iPhone 6 plus size review

By on September 25, 2014 in Technology with No Comments

Is the iPhone 6 plus too big for me? The answer to that question will depend on what you mainly use your smart phone for. More people are using their mobile phones for apps and watching videos more than actually making phone calls. “It’s important to note that Facebook’s monthly user base has grown 14 […]

There are several methods to share an article on Facebook via your iPhone. Copying the URL and pasting it as a status update is one way. It’s also the worst way to do it. This only shows the URL on your post, which could be some long weird name that doesn’t say anything about the […]

Checking foward and reverse DNS

By on October 18, 2013 in Technology with No Comments

Setting up a DNS record is important, especially in large environments. I dislike lazy sysadmins that don’t take the time to setup the reverse DNS record. You can check for this by adding a Bash script to your newly imaged servers via kickstart or puppet. This script alerts you via email if the forward or […]
