I have actually been building the static content of the site from a python(1) script for a while, though until recently it ran from cron(8) and rebuilt all the pages every hour. This wasn't too bad since there were a few internal pages that also got rebuilt, including my graphing pages that are built from SNMP queries of various network gear.

I am hoping this will be the first of three or four posts detailing some of the technical bits under the covers of the new website. In this particular post I'll talk mostly about the design decisions that went into the whole infrastructure.

I have lately started using MikroTik RouterBoards for various remote sites on my network. Mostly the RB951Ui-2HnD as they are inexpensive, powerful, and an all-in-one remote access solution. I typically only route prefixes for my network and networks I have direct VPN links to, but there are a few sites where I don't trust the local Internet provider and will route everything via the VPN.

So I found myself stumbling across /r/unixporn/ the other day and a fair number of people seem to use screenfetch to display information about their systems in the screenshots they post.

I found myself needing to make roughly 100 DNS records for a DHCP pool. In BIND I usually accomplish this with some fancy vi(1) work, but sadly this was for a Windows based lab at work.

In the previous post on this topic I talked about building my ADS-B receiver to feed FlightAware and FlightRadar24. I got decent results but was waiting for some final pieces to put the unit outdoors and attach the LNA and filter (some ethernet cables and an antenna in the end).

So when most people think about how they are going to spend a birthday they probably think about cake, cocktails, dinner, maybe presents. I thought a reasonable way to celebrate another year in the books was to complete a pretty major milestone in my flying career.

It is hard to describe the experience of learning to fly to people who have not done it. It is equal parts elation and frustration as you try to assimilate all the procedures, regulations, and knowledge required to become a pilot. Instead of a ``learning curve'' it is periods of frustration followed by discovery and joy. It is an investment in brain real-estate and muscle memory as well as the more obvious time and money.

I provide BaaS (Backup as a Service) on a NetApp FAS2020 to a number of friends using a vFiler on the system that hosts my public virtual machines (such as the one that runs this particular website). This provides separation and allows me to delegate administration of the backup location to the users that actually consume this data. When it came time to monitor the vFiler though I found that check_nac (which I use to monitor my instance) does not have access to vFiler resources. It looks like this is a limitation of the SNMP agent so the solution was to use the wonderful NetApp Manageability API.

Nothing major to report, went down to the Rochester Air Center last Thursday and after buying a new plotter (I seem to have lost mine between taking the practice test to get the sign-off on Monday evening and Thursday afternoon...) took and passed the written exam. I scored a 92% (missing 5 questions).

Last night was a perfect night to fly. No clouds, clear, nice strong wind from the south to help us scoot home.

In typical Rochester weather news, this week was forecast to be crap but all of a sudden it ended up being quite nice. In fact it was nice enough that I was able to get my night orientation flight in the book.

Last weekend I finally had the opportunity to get out and fly my first dual cross country. For those who aren't versed in the bowels of the FAA's flight training requirements a 'cross country' is a flight in excess of 50 Nautical Miles from your 'home' airport. The dual means I had my instructor along as opposed to the 'solo' variety which is still coming up. We planed to fly KSDC SYR KRME then KRME GGT KSDC.

So it's not a secret that I am a big fan of Debian Linux, and also not a secret that I am a big fan of NetApp's storage technology (I did go work for them when given the chance after all), however in the "Enterprise" world Debian is kind of a second class citizen. Most people have heard of it but RedHat kinda rules the day... Thankfully if you do it right Linux is pretty much Linux from a compiled binary standpoint.

| I have been spending a lot of time lately with the handy NetApp Data ONTAP 8.1.1 cluster mode simulator, including getting a lab setup at home. It's a fantastic product and stands to be a very disruptive revolution in the way enterprises manage and think about storage but all of that has been covered over and over again by people more articulate on the messaging than I. But since I monitor all my personal IT infrastructure with Nagios already I wanted to monitor my cluster (even though it is a simulator) as well.
