"Python/PHP is the same shit"

Actually, for most web apps, language is not the bottleneck.
Rendering an page normally costs less than 10ms, while the database accessing and network latency are much more expansive than it (maybe hundreds or thousand ms).

I don't think Java could do it better since it took more time for rendering a same dynamic JSP page and connecting to MySQL in my previous testing.
Don't think dynamic languages are always slow than static languages, you'll find the answer when you need dynamic features.

In my opinion, Java is almost the worst choice which makes everything much much more complex (normally 10x code lines), uses much much more memories (normally 3x memory usage), and also takes much much more money to buy suitable servers.

I've been a Java coder for years, I couldn't find any interesting of it.
The only superiority of Java coders I found was coming from the performance of toy programs. Otherwise, I can't explain why your friend likes complaining by using "shit" while Pythoners don't.

At least python doesn't use \ for namespace delimiter. lol

Just choose the language that will let you get things done, that's all.

按这人的逻辑，所有的动态语言都是垃圾了……
貌似在他眼里，只有C/C++才是王道了。
其实要看具体应用的，动态语言的开发效率不是静态语言能比拟的

@ayanamist 他玩PHP/C/C++/ASM

最后一段说得还是对的，语言不重要，你才重要

看不懂英文。。

重点在于，用Py的人鄙视PHP也不是一次两次了，还好已经习惯了……

@francis PHP有很多地方让人不爽的……某从PHP跳到Python后深深的感到Python的好，PHP的丑陋

机器编译的速度慢容易弥补，写代码的速度慢很难弥补。

@ayanamist 话说Python的确很不错，但是我觉得php也没什么丑的，2个语言风格不太一样，但是写起来感觉都挺爽

我觉得这人说的话并不是在贬低python或者php吧

php有trait，python有么？（找茬来的

@reus 首先确认你问的是不是这个： http://wiki.php.net/rfc/traits

粗略看了下，类似于Ruby的mixin。

A Trait is a unit of reuse much like a class, but only intended to group functionality in a fine-grained and consistent way.
Python是支持多继承的，所以没有traits。

简单来说，这个问题好比拿了台手机，然后问别人你的电脑键盘可以敲3下2打出个c么？

我还是不在乎你的女朋友比我的女朋友漂亮/跑得快。

@francis @ayanamist 说话者没有贬低任何一种他提到的language...

@keakon http://web.cecs.pdx.edu/~black/publications/TR_CSE_02-012.pdf 请阅读此论文并自行判断，我的理解是这个是比mixin和多继承更好用的实现代码复用的机制

快有2种：开发效率高和执行效率高~
Python属于前者，C/C++属于后者~
对于一个实际项目，语言选择最好是采用上动下静这样的体位~

“体位”一词来自这篇文章~

我现在过渡到NodeJS了....
改天玩一下神气haXe

shit means thing.
"it's a new shit"

除了脏话，说的挺有道理的嘛~

语言争论是没有意义的，完全可以说所有语言都是shit，因为根本不存在一种完全能在任何场合都胜任的语言。语言的好在于它适应了你的需求，脱离了具体的场景去比较是完全没有意义的。

what's really important is not to choose a language because it is "fast" or not, but choose a language because you "master" it"

看这一句就够了，其它的看了反倒容易造成误解。

＊/＊ is the same shit.

我的疑问是python真的没有字节码优化吗？

C++和JAVA基本就是手动档和自动挡的区别。各有各的优势。

C/C++, Python, PHP都在学习当中，暂不作评论，感觉各有各的用处
