Magento 用了 dynarch.com 的 calendar 1.0 javascript，有个 bug：无法得到 time 的值。 dynarch.com calendar 已经是 2.0 了，单独使用的话，能显示和修改 time 的值。 我暂时没想好该怎么办：我倾向于用 jQuery 去增强 Magento（prototype 我也用不好，其他的就更不要说了），但 jQuery 现下的版本只有 datepicker，官方还没有 datetimepicker。试过很多第三方 jQuery datetimepicker plugin，没觉得某一款有 jQuery 的神韵。

I could use Google apps account as my OpenId
Years ago, I knew OpenId. Years ago, I knew Google account supports OpenId as OpenId provider. Years ago, I knew Google apps premium version account support SSO. And I was misled by many threads that Google apps standard version account does not support OpenId. I did try several times without success, but I did not… Continue reading I could use Google apps account as my OpenId
Controller override and request rewrite in Magento
There are three ways to override controller in Magento. They fit for various purposes. The first and easiest way can be used to route the request to more than one module. When a request arrives on a frontName, it usually is rounted to a module. For example, /cms/page/view is routed to cms module page controller… Continue reading Controller override and request rewrite in Magento

What is web 2.0?
Web 2.0 这个名词都出来好多年了。它还是新鲜名词的时候，我买了本书 Web 2.0 strategy guide，太深奥，扔在那里没看。还已有人嚷嚷着 web 3.0，我现在再来讨论“什么是 Web 2.0”似乎有点过时。 迟了这么多年谈这个，跟我不是搞理论的有关。我倒不是说理论不重要，恰恰相反，理论很重要。我总结不出理论，只能关心我要怎么做才能 web 2.0。当然了，名词也不重要，2.0、3.0 当然就更不重要了，就说怎么做一个好网站吧。 话题的起因是今天看到一个论坛帖：几月几日某地到某地回程空车，找想搭车的。那个论坛纯属杂谈，突然冒出这个让我有点想笑，转念一想其实没什么好笑的——我22号要去 Heathrow 接老婆，也可以找搭车出程的。但我不屑于在那论坛上发帖，一是不看好那坛的人气，二是都 web 2.0 了，肯定有更好的办法。于是调查了一下，果然有，叫 liftshare。 唉，我怎么早先没想到呢？几年的独自上下班本来也可以 share 的嘛。唉，这年头只有想不到，没有做不到的。唉，题外话。 玩了一下 liftshare，感觉还不错。只是它在路线、时间的匹配上不是那么智能，毕竟 liftshare 的算法不是 IBM Watson，我提醒自己。liftshare 到底干了什么呢？它的卖点就是提供一种匹配互补行程的功能，网站不做任何内容，内容是行程，而行程都是用户提供的。 联想到 YouTube，网站也不做内容，内容是 video，而 video 都是用户上传的。而且，不上传 video 的用户也可以参与做一些既是内容又不是内容、半内容半功能的东西，比如说 playlist。YouTube 有成千上百的有关 jeopardy Watson 的 video，良莠不齐，我看了 Watson 的三天比赛 6 段 video，是不同的人上传的 。我留意了一下，还没有一个人完整上传过这 6 段视频。所以我把它们组织成一个 playlist，方便我介绍给朋友们看。YouTube 在其中干了什么？要说它什么都没干也可以，因为… Continue reading What is web 2.0?
Is it a serious security leak for WordPress bloggers?
By WordPress default settings, anyone who knows WordPress blog administrator’s email address can put this address in comment required field, and make comment without being moderated as if he was the administrator. I think it is very bad design of authentication. It worries me a lot although none of my blog users pretend to be… Continue reading Is it a serious security leak for WordPress bloggers?
jQuery dialog widget moves dialog DOM to the very end of body
我在 checkout page 上使用 jQuery dialog widget 来显示 terms and conditions。Terms and conditions 的内容不随 checkout 页面加载（因为大部分顾客不会去读它），而在首次点击 Read terms and conditions 链接后以 ajax 获取内容后用 jQuery dialog 展示。再次点击则不必再用 ajax 获取，而直接用 jQuery dialog 展示。 因为不同种类的产品会对应不同的 terms and conditions，所以 checkout page 会根据 shopping cart 里的所有产品列示出对应的 terms and conditions，可能会有多条。我原想把每条 Read terms and conditions 链接获取的 terms and conditions 内容插入在该链接的后面，在点击事件发生后就可以判断其后的内容 DOM 存在与否决定是否要执行… Continue reading jQuery dialog widget moves dialog DOM to the very end of body

The trash has reached its maximum size
估计 KDE 用户碰到这个问题的概率比较高。这个问题的起因不明，症状是要删除文件时出现 The trash has reached its maximum size! Cleanup the trash manually. 检查垃圾箱里没有东西，却无法删除文件进垃圾箱。直接删除操作不受影响。 问题的直接原因是 Trash 的 metadata 有误，解决办法是把 $HOME/.local/share/Trash 直接删掉，然后执行一下 Empty Trash 操作（其实是让 Trash 重建 metadata），以后就正常了。
