Dockerfile quicky - templating with M4
Creating abstracted Dockerfile is something I really wish existed. Every time,
I write a Dockerfile for a specific base image I must specify the correct
package manager command. You either use apt-get or apk or yum or any other
call for the package manager. This is unfortunately, not very reusable. But,
here is a simple schema how to use M4 macros to achieve this abstraction.
On learning Ruby coming from Python ...
I am learning Ruby, and coming from Python it's not a an easy thing.
Ruby is confusing, it has a weird syntax, and things are not really

Yet another case of Python vs. Regular Expressions
Regular Expressions are really awesome, and If you read the last post you might got the wrong impression I am totally against their use. I love using regular expressions, but sometimes, knowing Python is more than enough.
Python's regex is not always the best option
When programming in Python, regex are not always your best tool. This has a few reasons, regex can be computationally expensive, unreadable and unmaintainble, and finally, sometimes there is a better pythonic way without them. Here are a few examples.
