大家觉得Ruby和RoR怎么样？
呵呵

I think it's case by case. RoR hasn't been proven beyond
CRUD application.

RoR is not good for high performance systems. Take twitter for example, I
think they are RoR but now they are experiencing performance issues.
They are thinking to convert to java or php. So you figure...

我一个朋友的公司做payment gateway，用ROR做的，一个月的交易笔数200来万次
运行很稳定
大部分中小企业的网络应用这个量级足够了吧？

中小型企业用什么都差不多，Java至少IDE比Ruby要好。

I think transaction based systems are ok with RoR, but, for high performance
systems like twitter, they need something that's very fast. So, different
market I guess.

I think to use java or not. I would consider.
1. Legacy system, if you have some legacy system to support, chance is
it's easier to find a connector in Java
2. Security and reliablity. Java is proven in mission critical system,
can't say the same thing for dynamic languages, it's more likely you'll
get a runtime error using RoR
3. Extension and maintenance, it's likely you'll find a good 3rd party lib
for java, and have to write it yourself in RoR. How about thick client,
is it possible to suppo

As must as I like ruby for a script language, I've
never been a big fan of RoR - or any web framework
entirely based on a DSL.
I've been toying with the idea of incorporating
ruby into the JEE framework. Ruby is ideal for
implementing the more "volatile" parts of the architecture,
for instance the request handlers, the business validation
rules, etc.
OTOH, I'd like to stay with good old java for the
domain model, and the service and data repository tiers.

No matter what programming language you choose, the difficulties of software
engineering are largely contributed by the complexities of the business
requirements.

Another point to make, the performance of an application is mostly
determined by the database design and the data access code. Those simple
CRUD prototypes usually do lazy loading to fetch an object graph, no wonder
the performance is poor.

Given that most of the web apps are CRUD apps, I do think that Java is a
little too much for regular web apps. But nothing replaces Java for big
enterprise apps.
