美國政府暗中介入好萊塢的劇本,影響大眾對戰爭的看法

透過 Freedom of Information Act (FOIA) 取得的資料顯示美國政府 (包括了五角大廈、CIA、NSA) 如何介入好萊塢,影響大眾對於戰爭的看法:「EXCLUSIVE: Documents expose how Hollywood promotes war on behalf of the Pentagon, CIA and NSA」。

灰標「US military intelligence agencies have influenced over 1,800 movies and TV shows」可以看出影響的層面。

The documents reveal for the first time the vast scale of US government control in Hollywood, including the ability to manipulate scripts or even prevent films too critical of the Pentagon from being made — not to mention influencing some of the most popular film franchises in recent years.

從很意想不到的地方介入... 引用其中一個說明:


Jon Voight in Transformers — in this scene, just after American troops have been attacked by a Decepticon robot, Pentagon Hollywood liaison Phil Strub inserted the line ‘Bring em home’, granting the military a protective, paternalistic quality, when in reality the DOD does quite the opposite.

RSA Conference 2015 禁止 Show Girl

前幾天的消息:「RSA Conference Bans "Booth Babes"」。報導出自於「RSA Conference bans ‘booth babes’」。

規範的文字:

All Expo staff are expected to dress in business and/or business casual attire. Exhibitors should ensure that the attire of al staff they deploy at their booth (whether the exhibitor’s direct employees or their contractors) be considered appropriate in a professional environment. Attire of an overly revealing or suggestive nature is not permitted. Examples of such attire may include but are not restricted to:

  • Tops displaying excessive cleavage;
  • Tank tops, halter tops, camisole tops or tube tops;
  • Miniskirts or minidresses;
  • Shorts;
  • Lycra (or other Second-Skin) bodysuits;
  • Objectionable or offensive costumes.

These guidelines are applicable to all booth staff, regardless of gender, and will be strictly enforced. We reserve the right to request that individual booth staff change their attire or leave the premises immediately if we feel their appearance might be offensive to other exhibitors or attendees.

讓我想起 2009 年 Yahoo! 辦的 Taiwan Open Hack Day:「Yahoo Sorry About Lap Dancers at Hack Day in Taiwan–So What's the Excuse for Last Year's Go-Go Girls?」。

MySQL InnoDB 遇到 Deadlock 時的判讀

Percona 的「How to deal with MySQL deadlocks」這篇文章裡面提到了 MySQL InnoDB Deadlock 的判讀與處理。

在支援 transaction 的 engine 裡 deadlock 是不可避免的常態。

在 MySQL 5.5 以及之前的版本,可以透過 Percona 的 pt-deadlock-logger 這隻 script,每固定幾秒鐘就跑一次 SHOW ENGINE INNODB STATUS 記錄下來。在 MySQL 5.6 之後,可以直接使用 innodb_print_all_deadlocks 這個參數,遇到 deadlock 時就寫到 error log 裡。

有了 log 後,接下來就可以判讀 deadlock 的情況,得知是什麼樣的情況造成 deadlock。

文章最後面則是對減少 deadlock 的方法給了一些建議,都是比較一般性。一般還是要靠 bussiness logic 的分析來切割降低 deadlock 的情況。

不過這篇文章需要一些背景知識,像是 InnoDB Lock Modes 與維基百科上的「Multiple granularity locking」,對解讀會有更多幫助。

Gmail 將會自動讀入圖片顯示...

上個禮拜超熱鬧的消息,Gmail 將會自動讀入圖片顯示:「Images Now Showing」。

在 Support 的「Choose whether to show images」說明裡有提到這個機制是透過 Gmail 的 server 去讀取圖片,所以可以達到這些事情:

  • 發信人將不會知道你現在用的 IP address。
  • 發信人將無法設定 cookie 追蹤。
  • 發信人將無法埋入 malware 或是 virus。

但圖片一直都是發開信率計算很重要的指標,而 Gmail 這一次的行為讓這些發廣告信的廠商暈了...

然後正反兩方的意見當然都有,像是「Gmail blows up e-mail marketing by caching all images on Google servers」這篇的語氣就頗袒護廣告商,最後還以陰謀論的角度來解釋這次行為:

No doubt Google hopes this move pushes marketers to spend less on e-mail and more on Adsense.
