Opera 10.50 alpha beta comes with a set of nice improvements, including the long-waited HTML5 <video> tag, CSS Transform, CSS Transition, and some enhanced CSS3 properties like box-shadow or border-radius.

To quickly sum up the usage of those newly supported properties, just notice:

• CSS Transform and Transition are implemented with the -o prefix, so properties look like -o-transform: rotate(5reg);.
• Other CSS3 properties are directly implemented without any prefix. Notice that border-radius property is implemented without prefix, too, unlike -webkit-border-raidus in Webkit and -moz-border-radius in Gecko.
• HTML5 <video> only supports ogg format, the same and open format supported by Gecko / Firefox.

HTML5 Canvas Experiment « IO 9elements

用 HTML5 的 canvas 搭配 JS + audio tag 做出來的效果，非常酷… 而且這證明了 HTML5 如果成熟了，絕對有辦法把 Flash 給幹掉啊!!!

你都不知道 Flash Player 有多慢、多耗資源… 我現在完全可以了解為什麼 Apple 堅持不放 Flash 進去 iPhone 裡面。我光是用筆電開 Restaurant City，估計可用時間馬上就掉了至少一半，而且 CPU 狂操、風扇開始狂轉，說有多可怕就有多可怕…

Safari DOMApplicationCache Reference

Availability: Safari 4+ or iPhone OS 2.2+; for other browsers, I only know that Firefox 3 implemented partial ApplicationCache object and complete in Firefox 3.5. So in future builds of Google Chrome should support it, too.

Not known for Opera… I haven’t researched yet. But for the purpose of making an Offline-compatible iPhone Web App, this is enough for me so far.
