Ultralight camping - sleep system

In the hiking and camping world everything is a system or a kit. It feels awkward to use the glossary but at least we are all talking about the same thing. And I'm glad I did not coin the term or I might be postal by now.

Reading the first few points in this ultralight camping book I decided to go back over my pack. While I returned my Yukon Outfitters El Capitan for a sternum strap repair I decided to put my latest day hike system in my 400g haversack. Needless to say it felt heavy.

Here are the weights of my hammock gear(approx weight):

  • friendly swede bugnet (meant for ground camping and can be clipped but no zipper) - 150g
  • Yukon outfitter bug net - 320g
  • seatosummit bug net - 82g
  • seatosummit coolmax adapter w/insect shield - 280g
  • seatosummit thermolite extreme - 14 oz/399g
  • friendly swede sheet - 250g
  • other liner - 250g
  • Yukon fly and lines - 480g
  • 2goSystems poncho - 320g
  • Yukon featherlight and webbing cinch - 680g
  • Yukon V1 and webbing loops - 570g
  • 2goSystems Bivy - 480g
  • headnet - 30g
I have not included a ground tent here even thought I have an ultralight SMD. Big Cypress is just too wet this time of year.

Where and when will I be hiking? For the foreseeable future I'll be hiking on the Florida Trail. That means lots of critters and plenty of water or rain. And then there are the temperature swings. And so with my ultralight nerd persona in action it's time to put some kits together:

Day hike
I don't need much more than water, snacks, rain jacket, compass, map, camp stool and maybe a hammock to take a nap. A poncho or tarp might be better than a rain jacket as it's versatile. Neither of the bug-nets are needed if my clothing is pre-treated with permethrin.

320g + 570g + 30g = 920g(32oz)

Overnight Summer
The summer and fall are very wet in Florida. Mosquito population blooms and it is hot and humid. And while you might not want to hammock in the nude to stay cool blankets, quilts and liners would seem to be hot or hotter. Therefore bug-nets have the advantage pointing out that the sea2summit is 82g. And since we know that rain is the thing then a proper tarp with more coverage is the thing.

480g + 570g + 82g = 1132g(39oz)

The head-net might be needed too but not necessarily as part of the sleep system. Also the hammock needs to be pre-treated with permethrin too. The hammock underside may be unprotected with the 82g bugnet.

Overnight Winter
Simply but; there are fewer bugs, less rain, and temperatures drop in the winter and spring. Granted it's only about 2 to 4 months of the year depending, however, one can skip the bug net and add the coolmax liner. [a] the coolmax has a pillow insert which is helpful in a hammock [b] insect shield [c] I was hoping I could find some thermal value on the seatosummit website but there isn't any.

280g + 570g + 320g = 1070g(37oz)

I could add the insulating sheets and treat them with permethrin myself. they are slightly lighter than the coolmax but they are slippery (silk like) and I do not like that feeling. Doubling up on systems in Florida like the bivy and a liner is simply not needed when using a tarp or a tent.

In conclusion it seems that the sleeping system is between 2 and 3 pounds. I need to gain some experience because there is something to be said for ground or cowboy camping when it's dry but in either case there is something to be said for just a little insulation for both.

UPDATE here is the winter kit configured. Not pictured is the sleeping bag liner/blanket. Notice the poncho is asymmetrical and that it ALMOST covers the hammock. If it was a strong rain the poncho would have to be lowered a great deal. The grommets on the poncho are very small meaning it's necessary to guy them out.

Prometheus vs Bosun

In conclusion... while Bosun(B) is still not the ideal monitoring system neither is Prometheus(P).

TL;DR;

I am running Bosun in a Docker container hosted on CoreOS. Fleet service/unit files keep it running. However in once case I have experienced at least one severe crash as a result of a disk full condition. That it is implemented as part golang, java and python is an annoyance. The MIT license is about the only good thing.

I am trying to integrate Prometheus into my pipeline but losing steam fast. The Prometheus design seems to desire that you integrate your own cache inside your application and then allow the server to scrape the data, however, if the interval between scrapes is shorter than the longest transient session of your application then you need a gateway. A place to shuttle your data that will be a little more persistent.

(1) storing the data in my application might get me started more quickly
(2) getting the server to pull the data might be more secure
(3) using a push g…

Entry level cost for CoreOS+Tectonic

CoreOS and Tectonic start their pricing at 10 servers. Managed CoreOS starts at $1000 per month for those first 10 servers and Tectonic is $5000 for the same 10 servers. Annualized that is $85K or at least one employee depending on your market. As a single employee company I'd rather hire the employee. Specially since I only have 3 servers.

The pricing is biased toward the largest servers with the largest capacities; my dual core 32GB i5 IntelNuc can never be mistaken for a 96-CPU dual or quad core DELL

If CoreOS does not figure out a different barrier of entry they are going to follow the Borland path to obscurity.

Weave vs Flannel

While Weave and Flannel have some features in common weave includes DNS for service discovery and a wrapper process for capturing that info. In order to get some parity you'd need to add a DNS service like SkyDNS and then write your own script to weave the two together.
In Weave your fleet file might have some of this:
[Service] . . . ExecStartPre=/opt/bin/weave run --net=host --name bob ncx/bob ExecStart=/usr/bin/docker attach bob
In sky + flannel it might look like:
[Service] . . . ExecStartPre=docker run -d --net=host --name bob ncx/bob ExecStartPre=etcdctl set /skydns/local/ncx/bob '{"host":"`docker inspect --format '{{ .NetworkSettings.IPAddress }}' bob`","port":8080}' ExecStart=/usr/bin/docker attach bob
I'd like it to look like this:
[Service] . . . ExecStartPre=skyrun --net=host --name bob ncx/bob ExecStart=/usr/bin/docker attach bob
That's the intent anyway. I'm not sure the exact commands will work and that's partly why we…
