Google 獨特的拍賣模式使用榮獲諾貝爾獎的經濟理論 4 來破除得標者的詛咒，也就是一種得標價格過高的感覺。雖然這個拍賣模式讓廣告客戶競標關鍵字，但是 AdWords 折扣器能夠確保他們所付的費用，只是為了領先與他們最接近的競標者而必須支付的費用。自從這套系統在 2002 開始啟動以後，這種長期的方法已經幫助 Google 吸引了超過數千名廣告客戶。
CenterICQ 這次從 4.12.0 一口氣版本號碼就跳到 4.20.0，看了一下這次的 log (作者 Konstantin Klyagin 寄到 mailing list 上的信)，不知道這次是為什麼跳這麼大，是因為 13 的關係嗎？:p
PGP encryption support was implemented for the Jabber module. In a nutshell this means that with a proper setup your communications get a way more secure. GPGME library is needed to build the PGP support.
Fixed the RTF parser that takes charge when a message from a Windows ICQ client is received. One problem was that it used to treat backspace characters wrong sometimes. Another problem with utf-16 was fixed with a patch submitted by Vadim Nosovsky.
After ICQ dual login detection centericq used to try re-connecting, though it wasn’t supposed to. Fixed.
During a long time noone reported me the bug related to libicq2000’s header files getting installed each time “make install” was run for centericq. Finally Wolfram Schlich noted this one, so I fixed it.
Logging on Yahoo! didn’t work on Sun Sparc machines. Fixed that. That might also revive Gadu-Gadu on bigendian architectures.
A couple of interface related bugs were fixed, such as a mistake in the group organization dialog as well as not clearing pending messages for contacts in non-chat communication mode.
