"Qt on Android Core Programming" Preface: Why write this book

In 2008, I started writing technical blogs in csdn. Before this, my ideal is to write a novel to be seen, I have been on the Internet forum his pen to get some results, but also published some essays and novels. And that year, when I picked up the pen again to write things, but chose the technology. This world, the only constant is the change, with the sex as I, what can accept, understand not accept, do not want to accept also accept, the goal can not be accepted, so the technical blog wrote for a few months do not want to write, but also persuaded themselves to accept, it seems indifferent to the appearance, but I do not like Yang Kun's "indifferent" This song.

As 2013 approached the end of the year, I decided to start writing a technical blog again. This time it was a rational thought, not the whim of the 2008.

In the 2013, I felt my brain capacity began to become smaller, the former project used a lot of technology slowly with the wind away, and finally gradually gradually away from the book, too much to ponder also difficult to tell. Is the iterative cycle getting shorter? Is it my machine that is starting to age? This time I can recall, is only the beginning of learning a technology has encountered setbacks and hesitant hesitation, once tossing and turning antigen sleep, no other, I do not want to do this: in old age squat on the threshold, the only can recall, is young once mastered 8 languages, developed 100 software, review my technical Road, I'm stuck in the phrase "think ...".

As Franz Kafka said, "Any obstacle can shatter me", some simple questions always stumble over people, and senior technicians don't understand why. In fact, he forgot that he had traveled the same way, Russell said the right, uneven polymorphism is the source of happiness, but we are too good at bushel, to their own rope people.

The hardships of the learning process, the accumulation of the gradual realization or the moment between the Daigo, with the passage of time, will eventually become a distant and vague memories, and you have been puzzled repeatedly stumble of the potholes, after the study looked so "incredible", so that you forget to walk, can not understand why people always in a place to make mistakes. Indeed, who will mark the place where he has repeatedly fallen, kid? Who will be the scrutiny of the experience of the breakdown of the written, open source to the post-scholar to make it to avoid the mistakes? In fact, I never want to actively forget their halfway decent beginner programming pain, but the son in Sichuan said, lost time husband, forget always happen, and we still move forward, if not to record, the years of wind and snow rain will bury you have walked the road. Therefore, write the article this matter, more is for oneself, write down also is put down, but can in want to use at any time according to write down the experience memory that wakes up at any moment, to others or can solve its confusion, self-interest person's thing, he le?

So I decided to restart the Technical blog Update tour, can not only identify their own learning model, curing the existing experience, the formation of a system of knowledge system, but also restudying, gain knowledge of the breadth and thickness. And the writing of this book is the origin of the article on my blog, I cannot but say it is an accident of joy. I am willing to complete this book without any cost in a limited time, which is my personal interest. A person should always have something at some point, let you go all out to complete, regardless of success or failure, do not want to gain and loss, all your motivation, just you like, you prefer to do it well.
