It is proud that we were the time-honored, a group of people who truly changed the world; Sadly, many of our programmers who are committed to changing the world are living in their own world, unable to extricate themselves and become "computer geeks" after "nerds". Computer is only a tool, we

By the time you prepare to read this book, you should have known and practiced 99% concepts in the book. -Esac2. programmer CultivationRecommendation: 1504This is an excellent book for programmers who have learned programming mechanisms. Maybe they are still in school, but they do not feel very safe about what they want to do. Just like the difference between sketch and architecture. Although you learned drawing in school classes, you can also draw

But it's not enough to keep a job going, and if you can't always do things better than the people around you, your enthusiasm will fade away and you'll start to wonder if your decision is right and whether your insistence is meaningful. So, my advice is to give yourself a period of

How programmers Choose Computers
In commercial office, there are so special with a group of people, every day to face the dense programming code, they are programmers. Programmers on the computer performance requirements are high, not only need to deal with complex operations and become, more competent multitasking, a good desktop computer is a better choice, to ensure the stability of complex work complet

In the past 50 years, few people have remembered the women behind the world's first computer ENIAC (Electronic Numerical Integrator and computer). As the world's first programmer, they created the software industry. A month ago, Computer History Museum-CHM awarded the lifetime achievement award to one of the world's ea

I feel that most of my labs are full of mixed life and there are only a few things I really want to do. In this environment, we need to strengthen our own recuperation and access more technologies. I hope to read more b
