How not to conduct an interview

I came across this interview question site and it drove me to fits. Anyone who would use this site, it's questions, develop or use interview questions like it is just stupid and lazy. The site represents 4 years of college and two years of ACM competitions.  At the time they were fun but they are meaningless in the context of the work I have performed over 35 years.

In my professional programming career I've only had to implement or model against a standard deviation once. And never once had I specifically answered an interview question that was remotely related to any higher level math. Let's face it... these questions are all derivatives from university studies and while that was 25 years ago I wouldn't remember any of these the day after graduation.

The frustration is that while I was in college we bumped chests and high-fived with the idea that university was teaching us to research and think critically. The specifics of maths, physical sciences or humanities were actually unimportant.

And now that we are on the outside looking for work it has changed from that to can you fit the packages on a truck. Of course it's important to FedEx and UPS but if you are building an email client or text editor where is the parity? Looking at that site I have no particular favorites or raspberries ... I know I hate them all.

When I interview a candidate I'm looking for just a few things:

  • aptitude - does the candidate like the field and are they likely to stick with it
  • are they arrogant to excel but not enough to disrupt the team or quit prematurely
  • focus - watch out for the butterflies and shiny new tech.
  • lazy enough to be efficient

(**) it's better if the candidate is smarter than me too. And I favor individuals who have changed their primary language at least once.

The difficulty, every time, is trying to customize the interview so that I can make an intuitive score on these attributes. I'm not perfect but in my career and hiring 100+ candidates I have only made 3-4 sub par hires and 2 of the four were under duress from management.

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…
