2019 year-end summary - J_Knight_

emm, looks like a belated annual colorectal, though, in time for the Lunar New Year 2020 finished TT

2019 harvest in general, whether in technology, work, values, ability to invest, contacts are very large: since I can say is the biggest change in my own practitioners a year.

Here from five aspects this year to expand the personal summary.

1. Technology & Workplace
2. investment
3. reading
4. life
5. 2020 outlook

1. Technical & Workplace

First technically, the biggest change is in the technology stack opened a new branch: Java development background. The reason is that the limitations do not want to end in the mobile platform, while the group is also suitable for this environment and I started the project. So it took a bit of background development work. The current work is mainly to iOS development, Java development, supplemented by background.

Java after the advent of Objective-C, the same object-oriented language, Java is not difficult transition in the writing, publishing and Java projects in this area convenient than iOS APP lot (on the line who had iOS APP Who knows TT).

And after contact with Java development background, I found backstage to learn and consider things very much, but in fact this is the reason for me to learn the background: the system point of view to consider a project, but not limited to mobile terminals.

In iOS development, we do some optimization and learning SDK design, the performance and improve the SDK development capabilities.

Also worth mentioning is that this year's pay to learn some technical courses, completion are:

1. iOS development master class
2. Code sophisticated road
3. 10x programmer Work Act
4. Message Queue master class

Still learning include:

1. Compiler theory of beauty
2. Something about network protocol
3. Asked 40 high concurrency system design

The above courses is good, each of which are not long, only to explain the basic thing; learning good rhythm, you can dash, taking notes. Some courses are more wonderful comments below, it is worth learning. Especially for areas not familiar to explain by experienced developers can relatively quickly build on our knowledge. At a minimum, you can let us know about the framework and ideas.

Workplace this year increased more is the ability to communicate, in fact, because it is more communication time relationship. Mainly because I do SDK related development, the need to integrate some business there, even some I integrate both iOS and Java in two parts.

The business integration will require some communication (some projects and not just a team), so this year I should be doing most of the year to communicate at work, but also communication skills to enhance the biggest of the year. A year later probably know a method for cross-team communication, mobile terminal and the other to take the lead as a mobile terminal, the back end of the communication; as a back-end developers communicate with each other back-end, mobile terminal; as the owner and other projects, products, communication development, etc. Wait.

2. Investment

In addition to technical learning precipitation this year, but also to do one thing, but also began to do this thing, it is to invest in A shares, Hong Kong stocks, US stocks. Overall, the results can also be, A-share stock earnings + 40%, the United States and Hong Kong stocks return 30% +, 20 +% income of the Fund; details can see my summary of this investment: 2019 annual investment summary .

This article from my public investment numbers. In the second half of this year, I feel like I can be the same number of public technology, recording some of their investment in learning things and feelings, then opened a "compounding vitamin" No public in June, and start the update at the end of July, until now the public number of circumstances:

• Fans are currently 1800 +
• Article 27
• Micro-channel public fan base No. 2, where the first group already full

This year in addition to these benefits make the investment, but also to get to know a lot from the brokerage, insurance, professional investors and other businesses, like-minded friends. We in the group which will discuss and exchange ideas about investment, a lot of harvest. Group 1 and group 2 there are some big snowballs V forum to help out, in addition to sharing their own articles outside, will share some of their ideas, which all of us are invaluable.

And to hear some of my friends make money after following me to buy some investment targets (stocks, funds) when still very happy, and sometimes also make happier than myself because I know I have a positive impact on others, this I also learned in terms of investment and establish confidence. This fact, and colleagues to get there before the offer was similar after seeing my article. So I want to stick to it ~

For programmers, an investment is quite advantageous. Advantage relative to wages in other industries, especially the more advanced line of programmers: there is only money guaranteed wealth management which in fact is a pity (taking into account the market and the compounding effect). And programmers also must continue to learn a profession, and this investment is to do the same.

Some might say that programmers busy, can not read the disc, but for professionals who do not have time to read the tape, there are corresponding investment strategy. Detailed contents can be seen in my article: Why do I put myself as an investment interests .

Investment with the intention of friends can focus on my personal investing public number. After attention, in reply to micro letter backstage "audience" added the public administrator complex number Lijun friends (actually I ^ ^), the administrator will give you pull into the audience.

This year met a lot number of the primary public through other means such as public numbers:

• Melon (No public: let technology were eating a melon)
• Architect (Record Maker App Developers)
• Fritters (Public number: Meng pet vitamins, pet Meng Diary App Developers)
• Zhenhua (Apple invited developers tomato App list of participants)
• There are number of other main investments, please see: recommended me in public finance and investment No. No. owners to get to know this year

There are also just recently learned knowledge and public investment in the last number:

• Peanuts (Public number: Decade 1024 times)

In terms of investment most grateful or early 2019 to join the lonely planet small birch stocks, micro-channel exchange group in the planet's where I learned a lot. Lonely small birch should be known I would most stocks programmer, 19 A-share performance is + 100%, the highest gains in US stocks was 600 +%. US stocks added to the planet in ways that respond to vitamin background compound interest, will be added to boot.

3. Reading

Reading the book is divided into technical and non-technical book two kinds.

3.1 Technical Books

Reading this book is less technical, but most are more difficult, so read more slowly (the feeling is jiekou):

1. "Reconstruction of the second edition of"
2. "Algorithm graphic"
3. "Westward data structure"
4. "Effective Java Third Edition" (~ 80%)
5. "Architecture neat way" (~ 70%)
6. "MacOS the iOS and performance optimization" (~ 50%)
7. "Pragmatic Programmer" (~ 40%)
8. "Java core technology Volume 1 Basics" (~ 30%)

Mo Kanwan part in addition to lack of time, there is reason for the difficulty from current knowledge system is too large, so progress slowly, but in 2020 would have ended.

3.2 Non-technical book

Reading this book are basically non-technical aspects of the investment book, a total of 30, the number is relatively larger; the reason is more interested in addition, there is a low degree of difficulty of these books, some books and few words; and with Kindle APP look very easy to see anytime, anywhere, you can use pieces of time:

I can see the details of this article: a brief summary of my book in terms of financial investment in 2019, read the (total 30) .

4. Life

In 2019, the biggest gain in life is licensing, and can be considered completed a major event in life. Follow-up as head of the family will take care of life and family assets, to contribute to improving the quality of life at home.

It followed made a memorable international travel: the National Day in Dubai and Abu Dhabi's time to play again. Although I spend a bit more (but better stock market this year good) but the feeling is very worthwhile, as detailed below: 2019 National Day Travels Dubai .

5.2020 Outlook

Article the beginning of this year when I mention his big change, but change is inevitable because so much invested a lot of time to do change, and the time is always limited: because the investment this matter, I hold a lot of things , such as short video, fitness, TV series. Moreover and family, classmates and few ties, especially the contribution of the technical community very, very small.

Reflected in the above Nuggets after March there will be no updates; and technical public number (programmer vitamin) is not the original technical articles. Tidied notes had no time to sort out the update up, but 2020 will find the time to do. Here is an apology to the TT technology fans.

According to the current situation, in 2020, the same should abandon the short video, fitness (fitness fitness ring with adventure replaces the experience quite good, mainly no time), TV. But the family, classmates and contribution to the art community should do. In order to do these things, in fact, still need more time, so I decided to get up early years after the start of the time to do something squeezed out.

In addition, the technology, investment and aspects of reading to do:

1. Technology: continue to carry iOS; SpringBoot on Java can be used to do some back-end pure small projects. And whether it is iOS or Java, or to look at some of the source code framework, learning good design, especially the Spring framework of this system.
2. Investment: continue to maintain superior profitability of the Shanghai and Shenzhen 300, continue to improve its investment system
3. Reading: technical books: read some classic books abroad; non-technical books: Keep reading investment books, the establishment of their own investment system.

Look for stocks of investment is the company's continuing growth, while we, as individuals, then why do not need sustainable growth? Because we belong to itself an asset - human assets.

I believe at a later time, I can continue to learn, and can have a positive impact on others, 2020 refueling ~
