Preview Color Tool in Snow Leopard 20 Sep 2009
I used the Preview Color Tool a lot in Leopard, mainly for picking color from an image. For reason unknown Apple has removed the Color Tool menu from Preview.app in Snow Leopard. Since the Annotations Tool also uses the color we can still show the Colors Pane, here's how:
- If the Annotations Toolbar is hidden, show it by View → Show Annotations Toolbar (shortcut: command-shift-A).
- Click Arrow (or Oval or Rectangle) to toggle on an annotation tool and enable the Color Menu icon.
- Click the Color Menu icon to bring the Colors Pane up to front.
- Now do whatever you want to in the Colors Pane.
使用wake on lan远程唤醒 13 Aug 2009
客厅里的那台htpc，在无下片任务的时候，大部分时间里都在白白浪费电。主板是支持wake on lan的，把它弄成可以远程控制会比较经济。
首先要设置bios，将电源管理下的 Wake On Lan (或叫PME Event Wake Up) 启用。
Snow Leopard下使用华为天翼3G网卡 10 Aug 2009
中国电信天翼3G搭配的网卡之一华为EC1260可以在OS X下使用，但是仅支持10.4和10.5。这款网卡在Snow Leopard上无法正常工作，运行MobileConnect程序会直接崩溃。
这也怪不得华为，毕竟这款网卡上市的时候离Snow Leopard的发布还远着呢。作为用户来说，我们当然也不能在未来的一年多时间里由于升级操作系统而放弃使用已经购买的3G网络服务。好在问题并不复杂。
VirtualBox NAT vs Bridged Adapter 31 Jul 2009
I've encountered networking problem for VirtualBox guest OS (Windows XP) several times. It's very slow to access internet. It appears that the default NAT doesn't play very well. The problem was solved by attaching the network adapter to Bridged Adapter instead. To do so:
- Shut down the guest OS
- Go to Settings - Network
- From the Attached to drop down list, choose Bridged Adapter
- Start the guest OS and try it
I mainly use VirtualBox on a Mac. I have friends who run it on Arch Linux and they also have this issue.
Rename James Chan -> James Chen 16 Jul 2009
I've been using James Chan as my English name for quite a long time. I did some search years ago (at that time there was even no Google) and found that people usually use Chan for my Chinese last name 陈, so I took it as mine too.
This confuse people a lot, especially for those from Mainland China Chan looks and sounds quite odd. Chan is used widely in Hong Kong, where 陈 is pronounced like that in Cantonese.
Migrate to jekyll 15 Jun 2009
I'm migrating this blog from WordPress (self hosted) to jekyll, so in the future I don't need to worry about database backup, workpress upgrade and other house keeping anymore. The blog source will be on github, and the generated static pages are hosted on my own vps. (github offers CNANE for paying account, which saves even more time and energy)
I've been publishing new blog entries with markdown for more than one year. This means most entries are safe to move. There might be some style or data lost, but that won't matter much. I've also imported most comments to DISQUS, which will be used as the comment system from now on.
