Introduction

Last year I wrote about my favorite podcasts so I figured I'd do the same this year. In no particular order, though I will call out the ones that I'm still listening to first.

Merry Christmas, Happy Hanukkah, Happy Saturnalia, Happy Festivus, Joyous Yule, and congratulations on surviving the solstice to everyone. Be safe and enjoy some time with the people that are important to you this holiday season as the Earth hurtles towards perihelion.

If you have read my previous post about monitoring my ADS-B receiver it probably won't come as a surprise that the impetus for this whole project has been to deprecate MRTG from my environment. MRTG was a fine enough tool when it was basically all we had (though I had rolled a few iterations of a replacement for personal projects over the years) but these days it is woefully dated. The biggest issues lie in the data gathering engine. Even a moderately sized environment is asking for trouble, dropped polls, and stuck perl processes. MRTG also fails to provide any information beyond the aggregated traffic statistics.

I'm trying to figure out a way to balance the lack of surprise and schadenfreude I have at Tumblr/Verizon's decision to paint all sexual content with the regressive and transparent 'but think of the children' brush. Tumblr grew largely thanks to the alternative and adult communities that found its permissive and accepting nature welcoming. It became what it is today because of the LGBTQ+ and sex worker communities, and now it has decided to break up. Their post paints a pretty picture full of platitudes, inclusiveness, acceptance, and love of community but it is obvious to the most casual of observer that it is just a sham. Tumblr is breaking up with the people that helped it grow because it is easier than trying to actually make the service a better place.

I have been running a FlightAware / FlightRadar24 ADS-B feeder for almost 4 years now. It is an older Raspberry Pi B with a RTL-SDR stick running dump1090 at its core. These days it is mounted in my garage with the antenna on the roof. When I built it I stuffed a Honeywell HIH6130 temperature and humidity sensor in the enclosure. At the time it was mounted on a fence in my back yard so it would be in full sun for much of the day so I hooked it up to Icinga to alert me if it ever got too hot or too wet inside.

While I was waiting for new tires to be put on my car today I was able to watch the landing of Mars InSight which was relayed via the MarCo A&B experimental interplanetary cube sats.

I know it's not particularly uncommon for web sites these days to drastically change things and in fact most people consider this a feature. The fail fast mentality is great and all except that it means you are often failing more than not and the general consensus seems to be that it's perfectly acceptable to do it in public to the detriment of your users.

A little over six and a half years ago I left the Linux as a desktop community for the Mac community. I replaced a Lenovo Thinkpad T500 for an Apple refurbished late 2011 MacBook Pro and honestly have not regretted it.

It's probably too late to change anyone's mind, but I saw a particularly salient Twitter come across this morning.

Getting Started

Tor in Containers

I have been looking for reasons to try Docker on one of the random stack of un-used Raspberry Pis that I have laying around and thought it might be fun to build a little travel router. Somehow that morphed into lets get Tor working on here and then well if I can get a client, and a relay, why not an onion service?

I was making some firewall changes last weekend and while watching the logs I discovered that every now and then some host would try to connect to 169.254.169.254 on port 80. This was peculiar since I don't use the IPv4 link local addresses anywhere in my network. It seemed to be happening randomly from all of my Linux hosts, both physical and virtual.

I installed one of the Mojave public betas last week on the Mac Mini I have in the office. I used it as an excuse to finally tweak a script I wrote for customizing macOS out of the box.

For a while now I've used a Yubikey Neo as a PIV card to authenticate to my public facing hosts. This is fairly straightforward but requires a host with OpenSC on it. In my .profile I have a function called add_smartcard which will add the PIV driver to the ssh-agent. This means I actually authenticate with the key that was generated in the Yubikey and not my password.

So, I mentioned a while back that I watch Acquisitions Inc on the yubtubs. Well through there I also started watching Dice, Camera, Action. During the Stream of Many Eyes event there was a DCA episode featuring Travis McElroy and that reminded me of the fact that I have had The Adventure Zone languishing away on my iPhone for a while now, un-listened to. Now I'm pretty terrible about keeping up with podcasts (there is so much good stuff out there to listen to and watch these days) so I just wanted to toss out a few words about what happened next.

Recently I had a rental VW with the fancy new radio in it and I figured I'd give CarPlay a shot.

Welp.
