多说总能看到好东西哈哈
大神您要蛋定,蛋定了之后说话比较有水平,看起来也很high
我说的ui和多线程这个恰恰是我最近一直在琢磨滴
先说ui,ui的主要问题在于,如果你不思考内存的使用
上来就用一种很简单的方式去操作ui,几乎在一瞬间就会挂掉
一个简单的60fps的屏幕刷新,就会有严重的闪烁问题
所以让人不得不去考虑一些很低级的问题,就向您说的
opengl的编程比c还恶心
不过所幸的是,一般工作不需要我去处理ui的问题
我玩ui完全是个人兴趣所致,倒不是说靠这个混饭吃
所以大神您谈ui,我很爱听啊,哈哈
然后ui如果再结合上多线程,乖乖不得了,这个简直就是要人命的玩意
目前貌似没有完美的解决方案,都只能采用一种伪多线程
也就是保证刷新ui的主线程的效率,然后调低其它分支线程优先级的方式操作
大神对此您有什么更好的建议没有?
多线程是脚本语言的软肋,就像其它人说的mpp
你这个不上多线程你怎么办?像您之前说的绕开恐怕不是个好办法
您说对不对?

z****e 发帖数: 54598 | 9 专业一点就是paradigm了
java就是最接近纯粹oop的impl语言
其他语言有各自的定位
比如haskell是fp之类的等等
那从一个人使用语言的角度出发
越纯粹的paradigm越好
paradigm如果混用,哪怕只有两个
都会造成非常可怕的后果
就是各自表述,互相之间会冲突
例子?
c++和scala都是如此
c++是procedural programming(pp)和oop还有其他p的混杂
c++自己说自己是oop,其实扯淡,无数的人写成了pp
scala则是oop和fp的混杂
fp本身的历史很不堪,就跟小菊花说的那样
fp在oop以前造成了灾难性的后果
所以才有了oop的推广,最初几次oop的尝试都取得了一定的进展并发展到现在
你今天学的四人帮的最常见的design pattern那本书
里面就用smalltalk, c++和java做例子
smalltalk就是oop最初的impl
所以
第一,多个paradigm混杂所带来的后果是灾难性的
其次,某些paradigm本身就很不堪
比如fp
所以oop至少可以说是目前为止,少数得到大多数人接受的paradigm
所以... 阅读全帖 |

z****e 发帖数: 54598 | 10 当然说要100%只用一个p,有一定难度
但是尽量保持纯净性
java是这么做的
首先java保证自己是一个oop
其次,通过增加一些相对高级的类库
来添加其他的p
比如aop,你不用aspectj或者spring或者app server的话
是没有办法用的,而你如果主动去download这些东西的话
你应该知道自己在做什么
再比如reflection,也就是mpp
那这个大多数时候,不是常见的功能
而且学习有一定难度,很多人甚至搞不懂为什么要reflection
更谈不上使用,所以通过这种方式有效地控制了低级程序员乱搞
而c++和scala则基本上不存在这种控制
c++如果涉及到一些底层编程的话,那还有另外一种p
那就是imperative programming(ip)就有点汇编那种感觉
总之到底是什么p,弄到最后你也不知道是什么p
p就好比是一只军队的战斗纪律,如果战斗纪律混乱的话
那就意味着战场上士兵会有收到多个命令
肯定会乱,士兵一乱,等着死吧 |
