要不要等新 Mac Mini

liuhui998 — Thu, 24 Oct 2013 10:43:53 +0800

公司里有 MacBookPro，然后外接显示器 Dell U2312。

因为觉得笔记本难背，家里也有显示器 Dell U2312，所以想买一个 MacMini，方便家里有时写写代码、看看资料什么的。

本来想等 10.22 Apple 发布新款的 MacMini，但是人家不出，你也没有办法。

我现在纠结是等新款的 MacMini 还是就买老款的。

Daniel Lv 明天是否有喜事呀

请教一下 rails 论坛程序选择

liuhui998 — Wed, 21 Nov 2012 14:46:33 +0800

最近在考虑给公司的产品换个论坛，原来的是用 discuz , 现在想换成一个可以和 rails 程序集成在一起的论坛。

现在有几个选择：

forem 可以和原来的 rails 程序很好的集成但是好不能上传图片，可能要花时间自己改造
Rabel 程序功能比较符合的中国人的习惯它要求的环境是 Nginx + Passenger 或 Nginx + Thin，但是我环境是 Nginx + Unicorn, 不知可不可以跑起来，我目前 Unicorn 用的还可以，不想换。还有不知道它的 Memcached 需要多大的内存

希望大家多指教

ruby.taobao.org 少一个 gem

昨天就找不到这个包，今天再试了一下，还是没有

bash-3.2$ gem sources *** CURRENT SOURCES ***

我想问一下各位学习 css 有什么好的办法

liuhui998 — Sat, 19 May 2012 17:11:56 +0800

在项目上使用 rails 有了一段时间了

对我而言的最大问题是在 css 的使用上

设计师对于 css 不是很熟，所以有很大一部分 css 工作到我的头上。

我想问一下，css 学习领域有没有像：

railscasts.com

railscasts-china.com

这种网站

或是其它好的快速有效的学习方法

Grape 在 Nginx + Unicorn + rbenv 无法加载

liuhui998 — Thu, 26 Apr 2012 15:58:22 +0800

最近有一个项目，使用了 grape 来进行 api 的处理在本地是使用 WEBrick 在 development 下一切正常

class API < Grape::API prefix "api" version 'v1'

.......... end

但是布署到了服务器端后，查看 unicorn.rb 提示：

uninitialized constant Grape (NameError) /funny1/apps/menu/releases/20120426060007/lib/api/api.rb:7:in `'

详细 log:

rvm 下载加速

liuhui998 — Mon, 16 Jan 2012 14:31:15 +0800

今天注册了 ruby-china, 想先冒个泡，我把以前写的一个贴子翻出来，希望对大家能有帮助吧。

当时在看 @huacnlee 和 ruby-china 上的教程，但是 rvm 下载速度实在太慢了，于是改了一下：

http://liuhui998.com/2011/12/28/speed-up-rvm-download/

同时也谢谢 @huacnlee 的 ror 入门教程，写的很不错
