Book Review - Jump Start Git

The author has gone a little bit beyond Jump Starting to Git in the last of the chapters where he briefs about refs, reflogs, fsck, etc. 

The author has also given instances from the real world where a few git commands come handy. All these are important in setting the context of how Git helps in the real world. 

This book can always serve as a quick reference guide in the everyday usage of Git. Nice job!

Book Review - Jump Start SASS

This book is a page turner. I finished reading this book and got comfortable with Sass faster than I had expected.

What is to be truly appreciated is that the authors have taken due diligence to share their experience and perspective by way of showing some nice real-world examples and explaining them too. Not often, do you find this in tech books.

Kudos to the authors for their efforts to help the reader by way of sharing their experience early on where required.

Book Review - Jump Start Sketch


A great primer. Expect no more.

This book is for beginners - a great primer. It details what is what and how to use it for quick in your everyday use.

All said, one example of a simple web page design with the lessons learnt all through the book, would have been great and helped it gain the full 5 stars. It's because of this missing piece, I didn't give it a full 5-star rating.

Note: I am a developer that read this book to aid learning to prototype web-page design in Sketch 3.

You may get your copy from Amazon, should you want it.

Change screen orientation in GenyMotion

Pre-requisite
Ensure like in your Android Devices, you've set the screen orientation to Auto-Rotate. It should not be in Portrait or Landscape mode, otherwise the user actions in this blog post won't work. And that is correct behaviour :)

Chat between Agile Coaches - Case 1

The Context

In the United States of Fairy Land, there is this much celebrated automobile company that decided to embrace Agile to better position itself in the competitive market. The management at the top of the pyramid makes a huge bet on this initiative and extends its full support with much openness and belief. The company then hires hordes of Agile coaches from varied consulting firms. Its been a couple of years since this initiative has started and they wanted more Agile Coaches. They included another consulting firm in its basked and started to hire their coaches.

As things will have it, nearly every team has two coaches, one for processes and other for software engineering discipline. Mr. Gabbu is a certified Agile process coach (you name it and he has go it) who has been with a new product development team since its inception, for the last 6 months so to say. The team's management felt for a need to induce a software craftsmanship coach and calls for one. The company hires Mr. Kartz to help the team in technical discipline. Kartz has no certification to his credit and yet has the  all-round experience of learning things the hard/soft/nice way mostly from delivering software wearing varied hats.

It's day one of Kartz stepping into the company and being introduced to the team. Incidentally, Kartz and Gabbu seemed to be acquaintances from conference circuit. At the end of day, these coaches meet each other in cafeteria and have a conversation. A snippet of that conversation is below for you to read, think and share your thoughts in comments section below. Cheers!

Accessing localhost server in host machine from Genymotion Emulator

Genymotion runs on Virtualbox, and the default network configuration is “Host-Only”. Host-only essentially means all network requests within Genymotion are routed through the host machine. Put other way, the host becomes the network proxy for Genymotion.

Now should we run any service in the host machine that Genymotion needs to make use of, all we need to do is get the host machine ip address as seen by Genymotion Virtualbox. From host machine perspective, the name of the Genymotion’s network will be vboxnet0.
