回复了 CupTools 创建的主题 › Python › "Python/PHP is the same shit"

@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？

回复了 apoclast 创建的主题 › 问与答 › 怎么样才能保持每天早睡早起

想早睡早起？往东移民就行了。习惯2点睡就移民到东10区，以此类推。或者每天移几个时区，天天住宾馆。

回复了 julia 创建的主题 › Google App Engine › Entity key有没办法缩短？

转换的开销少于1ms，你愿意写很长的key为了这不到1ms的开销么…

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.

前几天还看到有人做短网址应用而被Google暂停服务了。Google指出提供这种服务必须要有能力和精力确保不被用于spam和恶意网站。
