Review: Chromebit

I really like the idea of a Chromebit I'm just not sure it's ready for daily or travel use.

During a recent business trip I packed my Chromebit in my go bag. It was so small and light that I nearly forgot about it when I was at my destination as I had already started working with my Chromebook and so there was no need. That first evening the geeks started bragging about their toys so I decided to break mine out. Since I had never used it I was expecting greatness. Once I finished the regular registration things and the update I was ready to go. Unfortunately the monitor I was using was a Dell curved 34" display with 3300x1800 (from memory). Disappointingly the Chromebit could not drive the display in it's best resolution.

So here are some observations...

  • depending on what is at your destination you will either have to bring or buy a keyboard and mouse
  • if you're planning to use it in a hotel room TV then the OSHA rating is going to be very low. Working from a bed for prolonged periods is terrible and it requires a different type of keyboard. And you cannot use the TV for anything else... I'm not sure how performant the device is when listening to music or watching video at the same time. This is worse when you're traveling with your family.
  • even though logitech has a few tiny keyboard and trackpad combos the keyboards are really small.
The jury is still out but not looking good.

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…
