1.java,.net,php, which one should I learn and which one should I use?
They can all write high-performance, scalable, usable, and safe programs. Government software does not trust windows servers. They think linux is more secure, so .net is naturally excluded. Some companies’ computers are equipped with windows systems. They think this is very good, so .net becomes a good choice. webapplication, I chose PHP for its affordability and easy deployment. Don't worry about copyright issues. free. So one of the main reasons why many web2.0 websites, webgame companies choose php. php does a good job in request processing, but there are also some unsatisfactory aspects. For example, it does not support multi-threading. I saw someone on the Internet using php to simulate multi-threading. In fact, it puts the cart before the horse and does not work. The original purpose of increasing performance. It is better to choose a language as a supplement and use another server to specifically handle the message queue. At this time, whether you choose .net or java, depends on your choice of windows Threads are still linuxthreads.
2.Which platform is more efficient.
To this day, java, .net, php are actually very efficient, and even if the application volume reaches a certain level, they will not be able to sustain it. If you need to expand the hardware, it depends on the scalability of your program. Increase the ratio of hardware to performance improvement, whether to support distribution, and whether to consider partitioning. That is to say, the coupling between unrelated functions is reduced to a minimum, whether the "pool" technology is used for rare resources, and whether it even supports parallel operations...
3.I amweb Front-end programmer! !
Front-end technology is no longer limited to the display of data. In 08~09, everyone’s biggest feeling is that the world is changing, society is changing, and technology is also changing. When our broadband speed changes from 4MBProgrammed, 40MB, HTML5The formulation of specifications has destined front-end programmers to do more data collection, data modification, and even pure data——SQL . In current WEB development, front-end technology has developed to the current stage, which may require more programmers than back-end programmers. It also requires understanding and innovation of data structures and algorithms. When network transmission is no longer a problem. google’s o3d runs smoothly, javascript, and what is the mission of a front-end programmer? I want to learn new ideas and the latest technology in functional programming when I enter the first one. I want to learn c++, operating systems, and object-oriented when I leave the first one. Increase understanding of the nature and principles of computers. Not impetuous, calm and positive.
Borrow the thoughts of Mr. Cao Jingxian, an old man who only met me 2. Across all disciplines, across ancient and modern times, and across the world, learning, resource reorganization, innovation, innovation! ——Studying can only let you know the wisdom of the ancients. Creation reflects your wisdom and your value.
