When code and operations collide :)

I’ve just seen CBT Nuggets video on YouTube entitled “How to Transition to DevOps” and though I cancelled their subscription quite some time ago it sparked my interest and made it very tempting to subscribe again (if only not my financial and time budget constraints).

I really like expressive quotes and explanations which use analogy and one from this video which I really liked can be found below. Along with some basic theory on what is and how to approach DevOps in this video Shawn Powers shows little demo which demonstrates how to use Chef recipe for configuration management, and next goes the following conclusion:

“…configuration automation is awesome example of how DevOps is kind of taking two different worlds the world of installing packages and uploading files and code which allows us to programmatically solve problems and put them together kind of like peanut butter and chocolate goes together to make a Reese’s Cup and it’s you know awesome it’s better than the sum of its parts…”

Nice. And I also need to try these Reese’s Peanut Butter Cups now even if it a bit violates healthy diet 🙂 Think it goes well with coffee and IT training videos (if consumed in limited amounts).

I just looked at DevOps courses available at CBT Nuggets at the moment and though it seems there is no DevOps overview/general course available so far they already have courses on specific tools (Puppet, Chef, Docker, Ansible).


Understanding computations in R

Well it is actually not even a post, but I just wanted to jot down this quote of John Chambers, the creator of R, which is helpful for understanding computations in R:

To understand computations in R, two slogans are helpful:  1. Everything that exists is an object. 2. Everything that happens is a function call.

Nelson Mandela on language

Being keen language learner and somewhat amateur linguist I just started quite interesting course on edx.org“Language Revival: Securing the Future of Endangered Languages”. This course offered by University of Adelaide and delivered by Ghil’ad Zuckermann and Rob Amery. Course promises interesting overview of such things as linguicide (language killing) and glottophagy (language eating) and most importantly language reclamation as response to that (why and how). Course will use case studies of Hebrew and Kaurna languages. I just started with course materials but already found it very interesting starting from palimpsest as a metaphor for language and the quote of 1st South African president Nelson Mandela which I wanted to jot down here in this post. Here is the quote:

“If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart.”

Nelson Mandela

This is proper way to look at the language which sometimes can be forgotten in the world dominated by some “dialect(s) with an army and navy”.

By the way Nelson Mandela learned Afrikaans during his time imprisoned in Robben Island. There is another his quote on language I found, this one from his book “Long Walk to Freedom” worth mentioning here:

“Without language, one cannot talk to people and understand them; one cannot share their hopes and aspirations, grasp their history, appreciate their poetry, or savor their songs.”

Nelson Mandela

“Err and err and err again but less and less and less”

The quote in the title of this post is from one of the recent episodes of Numberophile YouTube channel, and I really like this quote, so decided to jot it down here:


“The road to wisdom? Well it’s plain and simple  to express err and err and err again but less and less and less”\n

Piet Hein

The video I mentioned features Don Knuth (author of “The Art of Computer Programming” and father of the analysis of algorithms) speaking about the Dragon Curve, superellipse  and learning from his mistakes, here it is:


Garbage in garbage out

Found this nice quotation in “Governance of IT: An executive guide to ISO / IEC 38500” by A. L. Holt:


On two occasions I have been  asked [by members of Parliament], Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ I am not able to comprehend the kind of confusion of ideas that could provoke such a question.

\n(Babbage 1864)
