Precipitate, share, grow, and let yourself and others gain something! 😄

1. It's coming, it's already being done!

Scroll Kings, has the new year started?

During the New Year holiday, I stabbed nucleic acid three times, went to three places, and experienced three kinds of happiness. However, the holiday refill is coming to an end, and I also returned to my comfortable computer desk, and this comfort comes from the wide, large, and thick solid wood computer desk that I placed on my bookshelf, monitor, stereo, Ornaments, writing pads, and a MacBook Pro for content creation in an office chair and at your fingertips 💻

Then the new year is about to start rolling up from here again, but this kind of volume, is volume those fresh techniques that have not been written and learned, is volume is the field that has never been tried before, is Volume 's expansion of blind spot vision raises awareness.

Just like in the actual combat distributed project study initiated by Xiao Fu, joining the planet: the readers of the Code Farm Club are always tossing and learning on their own technical routes, moving towards another workplace, Another position, another pay hits head on. I believe that as long as you study hard and prepare for the battle, you will definitely have a harvest of gold three silver four, and hereby I would like to share the learning of this group of scroll kings, and give some motivation and reference to the partners on this road.

Second, what are they rolling?

They are in volume: Lottery Distributed Lottery Spike System - Four-tier Architecture Practice Based on Domain-Driven Design

In fact, some knowledge is not so difficult, but because it is inaccessible, so when you suddenly hear such technical words or technical solutions during an interview, defense, or job debriefing, you will feel that you have never heard of it, and because you have never used it. And it seems to be difficult. But this level is more difficult because you are not in that circle, and there is no corresponding technical soil for you to grow.

In particular, some code farmers from small companies or traditional enterprises want to enter the big Internet factories, just like asking you: Have you used RPC, what is the role of MQ here, What is your idempotence? How to design, have you used sub-database and sub-table, how to switch the data source of sub-database and sub-table, how to query the data after sub-database and sub-table, what is canal for, etc. You may feel a series of Unfamiliar scene and solution problems, but these problems are basically very common in Internet development. As long as you have participated in the development of a project, you will have mastered the implementation of these technologies.

Therefore, these partners follow the practical project of Brother Fu, and use such a large project to penetrate the technical knowledge system required in the entire Internet, so as to follow the core technology lines in the study and improve their own technology stack knowledge. Also, DDD , design patterns, data structures, algorithm logic, etc. are all applied in the project one after another, and see how these stretch a programmer to the direction of senior development and architect how to design and write code.

A brief topology diagram of this project is as follows: - Maybe you have learned not only project development, but also a lot about the architectural drawing method in the lottery system

Three, how did they roll!

Now that I'm in the car, of course I have to take everyone to roll it together. After all, I'm also the head of the roll king!

The entire practical project, including: large factory specifications, function implementation, operation background, scenario application and system operation and maintenance, covering 5 chapters and 36 courses, through video explanations, booklet documents, progressive branch development and submission of punch-in assignments to learn. The top three of this punch-in study are as follows:

</div>

• Check-in time: January 1st - January 31st
• Punch-in instructions: punch in within 21 days and complete 70% of the learning content. You need to use the STAR rule to describe the learning process, summarize the learning situation and record study notes and artwork.
• Good readers: sunny, orcl , one day eight glasses of water, Force , Cang then years, jumping pig, owned by Sri Lanka, congee porridge, not take heart, lalaquan and other members involved in the project plus 1700 +

👣 Next, let's enjoy the footsteps of the kings in the next volume!

1. 1st place: sunny day

• Nickname: Sunny
• Rank: 1st
• Tags: drawing monsters, hand coding, liver emperor
• Comments: Sunny's study punch is very serious, the learning content is complete, and the drawings are clearly organized. PS: A paper king who submits homework at 23:00 in the middle of the night!

2. 2nd place: orcl

• Nickname: orcl
• Rank: 2nd
• Labels: Kuaishou, Scroll King, More Ideas
• Comments: He likes to get to the bottom of his studies and study in depth. From the content of each article, we can see his learning, thinking and gains. He is also a guy who likes to submit homework in the middle of the night.

3. No. 3: Eight glasses of water a day

• Nickname: Eight glasses of water a day
• Rank: 3rd
• Tags: ruthless, smart, thoughtful
• Comments: If there are difficulties, you must go up, and if there are no difficulties, you must go up. From the study, you can see that if you keep digging deeply, you may not be able to come out for a while, but you must do it clearly after you come out. .

There are also many excellent check-in learning contents of partners here. Follow everyone's footsteps and have a learning atmosphere circle, which can make you better progress.

Project learning issue

Fourth, prepare for war, gold three silver four

Don't be asked questions in the interview, you can answer them if you know them!

In fact, many R&D partners will break through their own technical bottlenecks little by little, and then grow to the next stage, and some of these technical bottlenecks are really not too difficult, but you lack a learning circle. PS : Spend some money for yourself and make a valuable investment, just buy one less skin

1. Join the study

2. What can I learn

This is a project that integrates and develops the actual needs of the technology stack in the real scene . It will inevitably introduce the use of various technology stacks because of the needs to be completed, and will also be used to solve the three high problems in the C-side scene in the Internet. Corresponding technologies implement different types of solutions and solutions, and we can also understand such solutions as business domain model development in DDD. In the process of design and development, architecture design, technology application, and scene implementation will be involved. Each piece of content will have a lot of practical knowledge, which can allow readers to learn a lot, such as:

• How to develop distributed system architecture ( RPC , MQ , distributed tasks, sub-libraries and sub-tables)
• The combination of DDD four-tier architecture design and design pattern is implemented
• Code development specifications, requirements review, and operation and maintenance monitoring of Internet giants
• Docker operation and maintenance practices, environment, deployment, configuration, monitoring, logs, etc.

3. Who is it suitable for?

• R&D personnel with Java programming foundation and want to improve their technical ability
• Hope to improve coding thinking and remove bad smells from code
• Willing to become an architect, but still in a certain bottleneck period
• I want to join a big factory as a code farmer, but I always feel that I can't find a way

Five, as above, like a tiger adding billions

On the road of technology learning and growth, walking with fellow friends, like a tiger adding billions!

In fact, not only you who read the article, but also Brother Fu, all need a circle that can break through the bottleneck at each stage. Just like myself, I like to mix in the architecture group very much. Listening to the technical discussions and ideological collisions of the big guys can always give me a lot of experience and learn a lot from the big guys.

But don't narrow the road at any time, thinking that you have 123 in your hand and attacking other people's 456, who knows that there are 789. Therefore, we need to maintain a good empty cup mentality and constantly receive more opinions to improve our thinking. Whenever these contents are absorbed, we can always focus on new projects, technologies, and explorations. Get the application, you can also grow up a little bit.

come on! On the way forward, you will always meet people who are like you!
