After adding some upgrades for icanhazip.com, I wanted to go a bit further. Adding reverse DNS (PTR) lookups and traceroutes seemed like a decent idea! Want to beta test some new features on icanhazptr.com and icanhaztrace.com? Give them a try! Getting your reverse DNS entry is easy: $ curl -4 icanhazptr.com ord.icanhazip.com $ curl -6 icanhazptr.com ord.icanhazip.com Traceroutes are straightforward as well: $ curl -4 icanhaztrace.com traceroute to 126.96.36.199 (188.8.131.52), 30 hops max, 60 byte packets 1 212.
Today marks the fifth year that this blog has existed on the internet. I bought the domain on February 14th, 2007 and tossed together a quick WordPress installation (I can’t even remember the version now!) to hold my notes that I was gathering at work. Rackspace as an entry-level Linux system administrator. The abrupt change from “top dog at the startup” to “wow, I don’t know anything about Linux” caught me by surprise and I was trying to stuff as much knowledge into my brain as quickly as I could.
A videographer from CNN Money stopped by the office today to ask about what makes Rackspace a unique place to work. As soon as we got started, everyone started to make as many distractions as they could to crack me up. Very few succeeded. ;-) Thanks to @pinojo for snapping the photo.
Quite a few people who couldn’t make it to Xen Summit 2011 this year asked me to write a post summarizing my takeaways from the event. I’m not generally one to back down from peer pressure, so read on if you’re interested about the discussions at this year’s Summit. The feeling I had at last year’s summit is that Xen was on the verge of losing traction in the market. Very few distributions still had Xen support going forward and much of the discussion was around the lack of dom0 support in upstream Linux kernels.
I’ll be taking a short break from posting, but I should be back underway within week! Here’s what I’m working on during the break: MySQLTuner - Thank you for all of the e-mails with suggestions, patches and complaints. The 1.0 version of MySQLTuner is in the works and I hope that it helps you get more done with your MySQL server. Boxcheck - A new version of boxcheck.com is coming and it will include more tests for you to use.
