The real cost of containers

It's too bad that there have been no studies on the costs of containers. At least none that I know of an none that are not biased in some way.

Currently I'm working on a reporting cluster and while the usual etcd cluster with arbitrary worker worker nodes is good enough I realized that if my domain were evenly slightly more complicated that events like SDN (software defined networks) might require a complete redeploy; and while that is ok for a reporting system that has wide maintenance windows a 24x7 webapp might not have the same outcome.

Even so, as an operations person I would hate to dump the existing deployment without having deployed and tested the new environment. While this overlap makes perfect sense when using AWS or GCE, if I wanted to accomplish the same in a private environment I would need 4x or 3x the hardware regardless of how the hardware was partitioned.

Consider this: If you were going to perform green/blue deploy strategies in production just how much of your infrastructure would you need to deploy?

UPDATE: something I need to be clear about is that there is a thin layer between the hardware network and the SDN above it. That same network has an analog in the baremetal deployment as well as the VM, vSphere, environments.

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.

UPDATE 2017-10-30: With gratitude the CoreOS team has provided updated information on their pricing, however, I stand by my conclusion that the effective cost is lower when you deploy monster machines. The cost per node of my 1 CPU Intel NUC is the same as a 96 CPU server when you get beyond 10 nodes. I'll also reiterate that while my pricing notes are not currently…

Agile is still dead and has been since 1991

[updated 2011.09.30] yet another response to Agile is good.
When you have so much of you career invested in something like Agile, XP etc... it can be hard to see the forest for the trees. I had a consulting job in The Haag many years ago. IBM was the incumbent contractor at the customer site (a bank) but after 5 years on the job they had not written a single line of functioning code. In the office there were two teams of software people... both behind closed doors. The first team was the Data team and the second team was Functional. They rarely spoke and they never shared information. I was there for a week, introduced the client to OO and we had a functioning prototype. Smart people do smart things, You cannot make an underachiever exceptional by using Agile. Either they get "it" or they don't.
I just commented on a blog. I'm sure there is some validity to his post beyond observing that Agile Scrum is broken. It certainly is not what it was originally intended but for…

eGalax touch on default Ubuntu 14.04.2 LTS

I have not had success with the touch drivers as yet.  The touch works and evtest also seems to report events, however, I have noticed that the button click is not working and no matter what I do xinput refuses to configure the buttons correctly.  When I downgraded to ubuntu 10.04 LTS everything sort of worked... there must have been something in the kermel as 10.04 was in the 2.6 kernel and 4.04 is in the 3.x branch.

One thing ... all of the documentation pointed to the wrong website or one in Taiwanese. I was finally able to locate the drivers again: http://www.eeti.com.tw/drivers_Linux.html (it would have been nice if they provided the install instructions in text rather than PDF)
Please open the document "EETI_eGTouch_Programming_Guide" under the Guide directory, and follow the Guidline to install driver.
