Where did you see validate? I have not seen it before...

#18 楼 @kgen If portability is not a concern... Mac mini is a better choice

Don't do it if you don't like it. Go ahead and keep sharpening your PHP skills. PHP is good.

#16 楼 @riskgod If you read carefully, you will notice that PO wants to learn iOS development and needs to use PhotoShop. I don't know about you, but I find it hard to do either on Ubuntu.

I prefer Air. Especially if you are going to bring it around. Buy the 8GB model

hmm I only started looking Slim yesterday, I think you can do something like this

| Text1 #{ link_to 'LINKA', '#'} Text2 #{ link_to 'LINKB', '#' } Text3

However I have not tested it.

Slim renders faster than Haml, or so I was told.

Yes, change it to bootstrap or something

You come from python?

Self is the default

#14 楼 @chenge lol, I was being sarcastic ......

#12 楼 @badboy 懂 ruby 不懂 c 更更更可笑，懂 c 不懂 汇编 更更更更可笑，懂汇编不懂纯机器码 更更更更更可笑

usertimesheet.hrid= custom.value.to_s you called hrid on usertimesheet

usertimesheet = usertimesheetMap[entry.user.id.to_i] so usertimesheet is an element in usertimesheetMap.

We know usertimesheetMap is a hash, but not usertimesheet. usertimesheet is probably an array

btw this is not how we name ruby variables.

高手可以不用任何 Ruby 已有的东西 - String Integer if def … 通通不用，只用一个 Proc 编出所有东西来 XD

其实 mixin 也是继承，不过是经过巧妙设计的继承

Which service? Different service providers use different terms.

Usually an instance means a "resource bundle" - typically includes CPU time, memory, disk quota and bandwidth. You can see an instance as a VPS.

However it can mean other things.

#8 楼 @taozui That would be rails tutorial , the first link I gave you

yes, top to bottom

Please for once try rails server , so that we can know whether the problem is in your app or in the web server .

#2 楼 @mistbow apache can't run rails apps directly. try use rails server to see what happens

rails server

then visit localhost:3000

#59 楼 @orion_chang just install command line tools, where is the trouble?

#22 楼 @kgen haha that's OK, I won't be doing serious stuff when using phones anyway

#20 楼 @kgen 我在 iPhone 上一直可以打中文啊，只是把 mac 上的卸了

Is it hosted on GitHub?

No problem here

#12 楼 @lgn21st Ubuntu server is good. Ubuntu desktop is a mess

#5 楼 @syutran nono, that's not what I mean. We should not hold back our words just to avoid being blocked. However, we tend to judge other people by their political stands. That is normal - political stands reveal one's worldview after all. The problem is many Chinese people - myself included - were not educated to mutually accept different values. We start labelling each other on these issues. Then we form small circles. Then the small circles fight on every topics. Then people are annoyed and leave the community.

This happened in so many forums, and is still happening. The recent example would be the V forum. Political discussions are necessary. But there are forums dedicated to them. Ruby China is a tech forum in its very nature. I enjoyed its purity. So I don't feel comfortable seeing a political topic - especially when it may lead to destruction.

No offence. Just my 2c.

I've seen too many forums fell apart due to political discussions. I like ruby-china. Please don't ruin it.
