2020 corresponds to programmers, is a multi-year disaster, many companies have carried out different proportions of optimization and layoffs. Once the epidemic under control, will be looking for work in the peak period , from last year's interview experience, it will now simply write code for business people looking for work is particularly difficult for many manufacturers interviewer will be the underlying principle to ask questions, inspection System and if you really get to know the principles underlying. Environmental requirements higher and higher, so we have a positive change, the sense of learning.
How to become a master of iOS development, it is the ultimate ideal for many iOS developers. As an iOS development engineers, in addition to master the basic knowledge of iOS, to become familiar with the application development beyond understanding iOS underlying data structure algorithms, architecture and performance optimization capabilities, but also become the iOS development master essential skills. Further technical reserves are: cross-platform, visual and audio and video technologies such as reverse security attack and defense need to learn to master!
Being a high degree of engineer
As a technical engineer, whether you are engaged in the development of front-end or back-end development, T-theoretical and technical personnel are more suitable for the so-called "T" refers to both horizontal and vertical dimensions. The longitudinal depth of the problem is solved, the lateral breadth of the problem is solved. I am more respected and breadth to depth again, because the technology is a pass Belden.
As a highly mobile development engineers need to be able vertical depth, lateral thinking can have every question fully. For example, we need to implement a data point buried reporting system, the team hopes accuracy and real-time data management problems, if standing on the client's point of view, is to think about how to achieve a set of data is not lost, as well as real-time high buried performance reporting component. We know that there's a process model, memory model, synchronization mechanisms are very complicated, to do a high-availability report components do need to have some technical depth.
But if standing on a higher point of view, you will find components optimized reported data does not fundamentally solve the fundamental problem of the team. What is the point specification buried? What is the point of the process buried? Products, research, data, test data for which several teams have pain points? We need to sort out a buried point from product definition, a client Buried development, testing, validation, back-end data processing, data display and monitoring of the whole process. Data Governance for the team, we need to think about each point of the problem system, to consider the overall situation from a higher perspective.
Cross-terminal end of a single
As a born nearly 10 years of mobile operating systems, (June 7, 2010 announced renamed iOS WWDC conference) iOS development experience various update iteration, iOS system has been very well now, but also a lot of information and frameworks.
Recall, then iOS because immature and imperfect system, it has created a flourishing era of mobile development. In this day and age, we can always find a lot of optimization points, and continue grinding. As the complexity of applications and business requirements increase, simple single-point optimization client has failed to meet the demands of the business, such as in complex scenarios such live applet.
At this point, we are the first step is to get out of their limited role of the client, from a more global perspective of the problem, thinking. You need to understand that the client achieve just a small piece of content only.
If you received an upgrade H5 page opens speed task, the ultimate basis for optimization is that we can study in depth the principles of rendering and browser caching mechanism, the front and rear but what can be done, what we should do about it? In addition, the page where produce, how to publish, where to publish, how to download, how to interpret, how to render, how to measure and monitor the performance of the page, all of these are issues we need to think about.
From the platform to the station
I believe that many students are engaged in the development of iOS engaged in component-based, so-called component-based, means that can be compiled into a single app, generally only responsible for a single business, with its own life cycle.
Component-based client technology only the most basic abstract expression. How to understand it? With performance components for example, although the performance data we collect various dimensions of the application, but how to aggregate the data in the background, how to store, how to analyze, how the police, we do not provide a solution.
Each access application or takes a lot of effort to build a complete system, in order to solve this problem, the construction of integrated services began to appear, such as with Google's Firebase for each developer platform represents. In order to address different application scenarios, we continue to hatch different service platforms, this time in the station concept was put out.
What is it in Taiwan? Simple to understand is to unify these disparate platforms and a large platform. Some people may think we are not turn back the clock? Remember when we put a huge split into various sub-systems platform how hard yes. In fact, here in Taiwan, "unity", is more developer-oriented level, for example, use the same account does not need to repeat the registration, such as a closed loop between each platform.
At home, Ali in Taiwan is doing the best. Of course, Tencent, headlines these companies are aware of its importance, most recently are actively adjust the organizational structure, set up a special department in Taiwan. But whether in Taiwan or platform, is optimized by numerous large and small have to pile up points, they need to accumulate slowly, it is difficult in a very short time construction was very well.
to sum up
After nearly 10 years of grinding, iOS long past the outbreak, is now more stable trend, the mobile applications are more focused on performance and optimization, if you both technical depth, breadth but also it is certainly that it will be sought after by others.
So for a long time work experience is not developers, should first study the depth, breadth or expand it?
I suggest you should at least first pay a lot of energy in the field of technology, in-depth study and thorough, then go to the breadth of thinking.
This is because experienced programmers to learn something new very fast, because now is not so much new technology prone, the so-called new technologies are actually regroup and innovative micro-old technology. Growth is no shortcut, only the depth principle, to understand its implementation process, you can go further.
So whether you're in the start-up team, or in the companies, we must adhere to the study in his spare time, continuing to explore their technical depth. So in the future, whether it is the start-up promotion within the team, or jump manufacturers, such efforts can experience the future numerous interviews, raise a highlight.
