真人真事：CentOS apache test page 差點驚動 FBI （news by CentOS）

http://www.centos.org/modules/news/article.php?storyid=127

這是真人真事。一日CentOS團隊收到一封政府的電郵。
某鎮政府去信centos, 說他們的website給centos的人hack了.
而政府發言人所看到的, 是centos3 apache的test page.
像這頁:
http://centos.hughesjr.com/testing/noindex_new.html
並威脅CentOS開發人員若在12小時內不修理好, 就找FBI.

世事真是無奇不有。

最後一天

今日是本人最後一天在英國倫敦的日子, 三年在倫敦的生活, 就此結束.
雖不捨得, 但沒有辦法, 因找不到工作, 因所有公司都需要工作證, 都是要離開.
雖visa在10月31日到期, 但早些回港可更快找到工作.
本人當然希望能在英國生活, 但已盡了力, 看看他日有沒有機會.

恐怖襲擊

要不是同學們打電話來, 都不知今日有恐怖襲擊,
本來今晩和同學餞別的說.
幸好父親昨晚離開倫敦回香港, 若是今天就麻煩了.

恐怖襲擊已預了會來, 但猜不到會在倫敦伸奧成功後第二日出現.
今日還要是她的畢業禮, 亦是七七盧溝橋事件記念日, 世事就是有那麼多巧合的出現,
希望死難者能安息.

畢業

今日畢業, 終於以取得First Class Honour, 完成了3年的留學生涯, 希望能在英找到工作.

巴黎一日遊

今日和父親遊巴黎, 由於法國的房租貴, 因此只遊一日.
由London坐Eurostar到巴黎都只是3小時, 和去英國中部的時間差不多.
而價錢, 只比到中部貴些少而已.

到了巴黎, 覺得還是london的環境好得多.

巴黎的房屋感覺太高, 有5層, 而倫敦只是3層, 覺得巴黎比較密集, 而倫敦比舒服.
而且巴黎的交通比較亂, 覺得好像到了東南亞, 和英國有條理的感覺有很大的分別.

今日到了不少巴黎的名勝, 不過因時間有限, 很多都只是走馬看花就算了.

父親來英

因為畢業, 父親特地請了一星期假來參加我的畢業禮, 並順道過來旅遊.
