A Smooth Sea Never Made a Skillful Sailor

I was recently asked to write a script assuming there are 100 files and they're all equal-sized, how to process them evenly across 10 nodes. I went in completely wrong direction suggesting regex where my regex-fu is really not that strong. Thinking it over on a different occasion, I came up with a simple script that will do just that. Of course the simplest solution is the best. As usual, your comments are welcome. __author__ = ' artem ' nodes = {} files = [] for filenum in range ( 100 ): filename = ' file_00 ' + str (filenum) files.append(filename) for node in range ( 10 ): subset = files[ 0 : 10 ] nodes[node] = subset files[ 0 : 10 ] = [] for node in nodes: print (node, nodes[node]) and the output: 0 ['file_000', 'file_001', 'file_002', 'file_003', 'file_004', 'file_005', 'file_006', 'file_007', 'file_008', 'file_00

One great thing about subscription services like Safari Books Online is the choice of all great books available at the moment's notice. What I find happening over and over is that I would start reading a book and never finish. This post is a list of all books I started reading but yet to finish. Here it goes. ActiveMQ in Action    excellent book based on the first four chapters I read. I'm not giving up, just shifted in priorities. I intend to finish the book soon. I'm up to chapter 5. Hadoop: The Definitive Guide 2nd edition 3rd edition  4th edition     Hadoop bible, a must read for any self-respecting Hadoop engineer. I made a mistake reading this book first, jumping from Microsoft platform to Java and Big Data. I intend to pick it up again when 4th edition is released. This is a really an in-depth book and not recommended for first time users. After having some considerable time with Hadoop, this is the book to turn to. I read the chapters in no particular order.

   I am finding myself doing repetitive work once in a while and I've been thinking for a while how to automate the redundant parts of my job. I am familiar with Puppet, Ansible and SaltStack but I never played with Chef before nor Ruby before. I started reading "Learning Chef" and I was surprised to learn that Ruby is the primary language for working with Chef. The other interesting tidbit is that Chef uses Microsoft Powershell for automation on Windows. Onto the review...    The book is pretty easy to read and is intentionally beginner-friendly. The author right off the bat points out two more professional books for Chef, which I appreciated. Kudos go to the author for following a developer approach, referencing Stack Overflow and Ruby language creator's arguments for better programming practices and argument for scripting language such as Ruby vs. a compiled language like Java for automation. The 1st chapter is an introduction to automation principles and how
