prototype, reminding team members to keep their features and functions focused and concise, and when engineers suggest new features, He raised the wood and asked, "Where's the add?" "This piece of wood as a prototype always reminds the team to notice the actual experience." Finally, Palm Pilot was successful, and Apple's Newton failed on the contrary. In designing a Web product, the user Experience Department often produces prototypes to make people feel like a real-life product experience. Pro

Summary When writing a high-load server program with a large number of connections, the classic multi-thread mode and select mode are no longer applicable.They should be discarded and epoll/kqueue/dev_poll should be used to capture I/O events. Finally, we briefly introduce AIO. Origin Network services are often inefficient or even completely paralyzed when handling tens of thousands of client connections.C10K problem.

construction of individualized quality culture must be people-oriented, establish quality concept and cultivate quality consciousness. Therefore, a quality expert said: "Product quality is not manufactured, quality is a habit." "The IBM School of Management also has a famous saying:" Quality is because 90% in attitude, knowledge only 10%. "Secondly, the construction of personalized brand culture also needs to build a personalized marketing culture. Marketing is to realize the brand value of the

As a common consumer commodity, digital camera its basic principle is to use CCD optical coupling device to convert the light signal into electrical signals, after a/D conversion, data compression and so on through the serial port or USB port in the PC-side application control of the picture (mostly JPEG format) to the PC's hard drive. The current PC-side applications are provided by the camera manufacturer. Few people have noticed that some digital camera manufacturers provide developers with

When I was about to finish at noon today, I found a problem that was maddening.A lite AIO application should theoretically be more concurrent than a full version of the AIO application (because the full version of the transaction is more complex) and tested on the same machine.However, the test results show that the concurrency of the lite version is less than the full version of the
