, technology is linked through the way people live. Second, they all reflect the values of life, the vitality of youth culture, or their childlike innocence and family life. Third, they all take the customer experience as the core of the design philosophy. With these deeper things, managing the business model recently discussed in the magazine is actually not the most fundamental thing. Compare Google's ten creden, such as focusing on customer experie

It involves job hunting for college students, job-hopping for on-the-job employees, and how senior talents can deal with headhunting. What's more valuable is that Leo's many years of experience in human resource recruitment and interview work has been carried out to provide a thorough analysis of the job psychology of different groups of people. At the same time, it has also proposed solutions to corresponding probl

This week is busy. Made an electronic journal. Although the journal was created using iebook, many pasters and Flash animations are stored online. However, it is quite laborious to do it. It is the same style as the newspaper version. However, more and more things were added later. Finally, I made a 40-page magazine. There are military training diaries, military training photos, and new revelations. Especially the celebration information. I changed it

I will mainly talk about the award-winning bibliography (because I have recently been engaged in testing and defect management, I will talk about these two products later) Unfortunately, I have never read any of the general books, and I have read three of them in the second type of technical books, which are accurate to being browsed. To be honest, it is not easy to write impressive books. I noticed that both of the first prizes were published by o'reilly. Complete list of winners: http:/

A little bit of leisure time, so do a small color palette for the vast number of design friends to communicate with. This tutorial only makes the details of the method of tinting not modified and processed. When we make a film, we must deal with it carefully ah hehe! First, look at the original artwork Look at the effect chart: Note: This picture does not have any stamp modification, a little lazy hehe no cosmetic skin The original image looks more flat light level,

This picture was designed by Serbian illustrator Becha for a fashion magazine called "Silent Spring" (Silent Spring). This picture is a good illustration of the colorful clothes designed by the designer Ana Ljubinkovic in the form of poster posters. This piece combines photographic work and becha design elements. In this PS tutorial, you can learn how to combine photographic elements and hand-drawn design elements naturally into a single image,
