位置,也会做出同样的决定吧?我知道,你一定会,一定会以自己的命保护众人的平安。

所不同的是,你有能力全身而退,而我却只能以命换命。

即使如此,我也心甘情愿,因为我终于飞到了你的高度,与你并肩看那片临近地狱的天。

你不是说过嘛!地狱和天堂只是一线之隔,黑暗和光明只在一瞬之间。这一天、这一夜、这一刻,我终于明白了,也终于看到了你的地狱和天堂。

那是黑夜和黎明交错的色彩!

有枪声!我听到了枪声!

朵猫猫像从来没有经历过战争的单纯女生,对不远处传来的枪声报以极大的恐惧。香港六合彩不是为自己的生命担心,香港六合彩在为即将到来的一切恐惧着,到底发生了什么?我要去看看!掏出腰间的枪,香港六合彩克制不住想冲出去加入战斗。

你安分一点儿。阿土适时地拉住香港六合彩,将香港六合彩拖到床边,香港六合彩让香港六合彩明白香港六合彩的职责所在,之雾小姐将优优和堂主交给了你,你不能擅离职守。虽然阿土也很想冲到邀海轩去帮之雾小姐,可香港六合彩不能,香港六合彩明白自己的位置,更知道这一刻香港六合彩该做些什么。

不管事后会不会被人笑为懦夫,现在香港六合彩只想,也必须守住堂主、津庭叔和优优小姐。

每个人都有自己的责任,不管你想与不想,都逃脱不掉的。

该来

  3. 3. Timeline Review <ul><li>Alpha - 5/15 </li></ul><ul><li>Beta - 6/15 </li></ul><ul><li>Production - 7/15 </li></ul>
  4. 4. Alpha Release <ul><li>Much of the current focus is on the framework in the Alpha release </li></ul><ul><ul><li>Support for Sakai UI components and Java Server Faces </li></ul></ul><ul><ul><li>OKI OSID Implementations </li></ul></ul><ul><ul><li>Hibernate Object Relational Mapping </li></ul></ul><ul><ul><li>uPortal Integration </li></ul></ul>

  9. 9. Hibernate <ul><li>Evaluated by team led by Lance Speelmon of IU - excellent talk at recent Sakai architect meeting </li></ul><ul><li>Team is now at training in NYC with the inventor of Hibernate </li></ul><ul><li>Excellent performance (5% slower than raw JDBC) </li></ul><ul><li>Clustering and caching solution </li></ul><ul><li>Little secret: EJB 3.0 is looking like Spring inversion of control and Hibernate Query Language </li></ul><ul><li>We are go for Hibernate - Should have the jars in Alpha - maybe even one tiny implementation By Beta will have several OSID implementations </li></ul><ul><li>IU/Stanford have converted their OKI 1.0RC OSID impls to Hibernate and are going into production - Yikes - trial by fire :) </li></ul>
  10. 10. uPortal Integration <ul><li>Three versions </li></ul><ul><ul><li>Embedded - all of Sakai in a single JSR-168 portlet (Version 1.0) - Could be integrated into a uPortal 2.3 without modifications </li></ul></ul><ul><ul><li>Injected - uPortal 2.3 navigation is altered to support hierarchical navigation needed by Sakai. This is a modified version of uPortal 2.3 where Sakai has “taken over” much like CHEF and Jetspeed (Version 1.0) </li></ul></ul><ul><ul><li>Integrated - uPortal 3.0 - will look like injected but will work in unmodified uPortal 3.0 and use uPortal administration for layout rather than Sakai administration. </li></ul></ul>
