原创 想写晨写
书上说,那些牛人,都有晨写的习惯。所以自己也想晨写。晨写,就是当早上起来的时候,当脑袋一片空白,还停留在伟大的潜意识中时,拿起笔,想到什么写什么,不加修饰。据说这可以开发右脑,更可以获得某些平时难以追寻,难以抓住的都写伟大的思想。据说安迪生就有这样的类似的习惯,他躺在椅子上睡觉的时候,手里总是会拿着一个小球,当他熟睡的时候,手里的小球就会掉下来,然后把他惊醒。然后他醒来之后就会马上

转载 用户体验是个什么东西?用户体验如何评价好坏?怎样用一句话描述用户体验评价方法的核心?
个人对用户体验的目标是,做到“自然”。举几个例子,我观察3岁的小孩用iphone很容易上手。比如,iphone的开锁,小孩甚至不用学就会用。因为触摸是人的天性,同时iphone通过箭头图标,向右滑动的文字条(小孩看不懂文字),来暗示手指触摸向右滑动来解锁。自然和人的天性是一致的。大人因为成年后受污染较多,反而不一定立即学会iphone解锁,可能需要看文字解释来理解。所以不识字的小孩

1.很少有软件企业要招那种性格极端内向的程序员。2.面试时,要避免一问一答,要主动地在重点问题上谈谈自己的看法和想法,主动和面试官进行沟通。3.用人单位招收程序员一般有两种类型,一类是招来即用,一类是培训后使用。4.应聘者千万不要过度地表现自己的学习欲望,说一些“到单位之后,我会好好学习的”之类的话。用人单位要的不是一个学生,而是让你为它创造财富的。你不如说“我到单位后,将多做工作,为

转载 栈和堆的区别【总结】
1.1内存分配方面:堆:一般由程序员分配释放,若程序员不释放,程序结束时可能由OS回收 。注意它与数据结构中的堆是两回事,分配方式是类似于链表。可能用到的关键字如下:new、malloc、delete、free等等。栈:由编译器(Compiler)自动分配释放,存放函数的参数值,局部变量的值等。其操作方式类似于数据结构中的栈。1.2申请方式方面:堆:需要程序员自己申请,并指明大小。
