Talk About Those Interesting whatsapp database

With the Internet and mobile Internet sweeping the world today, Steve Jobs, Bill Gates, Larry Page and others have become contemporary myths. Many people say: Geeks change the world. The unfamiliar terminology, the weirdly shaped machines, the day and night upside down routines, all began to change from mysterious to interesting. Just like the great whatsapp database success of The Big Bang Theory, at this moment, the creations of geniuses who shine with human wisdom and light are attracting people like never before. Those imaginative inventions and exciting creations continue to appear in people's vision, not necessarily successful, but dazzling whatsapp database and gorgeous. Just like the flying human beings who dreamed, they tried different methods and instruments again and again, and even paid the price of their lives, and finally the Wright brothers fulfilled this long-cherished wish.

The first aircraft went down in history, and we can't forget those brave attempts to fly. Today, when Steve Jobs has extended "design" to the power that ordinary people can feel, we advocate simplicity, we advocate user experience, we advocate whatsapp database innovation, we advocate cool products, and we advocate survival. Those "cool" creations are not necessarily "good", but they are worth writing about. mouse and trackball Speaking of "cool" design, let's forget about the iPhone that blows the sky and Windows that almost ruled the world. In computing, the history of elegant, minimalist design is much older, and it seems to come more from that amazing whatsapp database kid named Engelbart and his invention of what he calls the "mouse." In 1952, a group of engineers in Toronto invented a cool thing - "trackball", which is a way to freely spin a predetermined ball and convert the rotation into a trajectory input on a Cartesian coordinate system.

Compared with the input of paper tape and keyboard, the trackball can locate the position more efficiently and intuitively. Due to technical limitations and almost no civilian demand at that time, trackballs were used more in the military field for a long time. It seems whatsapp database that the first trackball looks a lot more high-end than the first mouse~ In 1968, Douglas Engelbart of Stanford University led the team to try many times, and finally found that putting the rolling trackball in a "box" and moving with the box can make it more intuitive for people to be able to screen. position. After more than 20 years of technological innovation and redesign, the new mouse, the prototype whatsapp database of the mouse, has finally reached the public with the popularity of Mac and Windows, and has become an indispensable part of PC.
