LED bulbs the actual life


You're in the dark because the light bulb in the room has died and you're all out of spares. You head over to the local home or grocery store to get a replacement and you are face with an endless variety of shapes, sizes, wattage, lumens, incandescent, fluorescent, neon, and LED. The interesting thing is the prices are anywhere from $1.00 to $150.00 depending on the product's proximity to the front of the store and whether it is WiFi enabled and has multiple colors.

I do not remember when and if it's still enacted by incandescent bulbs were being taken out of circulation. And at the time of inflection the prices of the alternatives was crazy high. Now as things start to settle I have come to accept the fact that I will convert to LED. But there is one serious issue.

Look closely to the bottom left of the packaging above. "Last 22+ years" and "Lasts 10 years". There are 2 problems with this claim. [a] there is no way to guarantee the lifetime and in fact there is no such guarantee. [b] How would you know if it did not last 22 years? In the earlier model we accepted that the cheap price of the bulb meant that a replacement was $0.50 or less away. It was also reasonable to have a few dozen spares in storage. And in the case of an electrical storm replacing the bulbs would only cost $100 or less depending on the number of bulbs. My home requires 55 bulbs of different sizes, watts, and decor. At $5.00 a bulb that would cost about $300.

Still, the issue is that bulb lifetime is meaningless if there are no guarantees. So now what?

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…

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.

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…
