海底光缆修好了,Sourceforge 访问也正常了,07 年 1 月份当选的特色项目(Project of the Month)是 FreeNAS 。以前逛 Sourceforge 的时候总是会盯住那些访问量比较靠前的一些项目,其实有些特色项目就忽略掉了。FreeNAS 就是这样一个项目,我们总说创新、创新,FreeNAS 就是一个不折不扣的创新。
提起 NAS(network-attached storage) ,总要想到专有设备,价格不菲。FreeNAS 可以用旧 PC 机来实现"穷人的 NAS" 。操作系统用的是定制的 FreeBSD,硬件资源要求也不高(最低 128M), 上面的一层是 m0n0wall 防火墙,从而完成 PC 到 NAS Server 的转换,支持磁盘管理以及软 RAID。开发语言基本上是 PHP,提供全 Web 管理配置界面。 FreeNAS 支持 FTP/NFS/RSYNC/CIFS/AFP/UNISON/SSH 等众多协议。
家里如果有旧的 PC 机的话,买几块大的硬盘,自己搭建一个 NAS,用来存放多媒体倒是不错。
项目组的核心成员年龄都不算小了,最小的 Oliver Cochard-Labbe (他也是项目领导者)也 29 岁了,其他几个人都超过 30 岁。国内超过 30 岁的 IT 人还有这个心劲儿来做这个么? 怕是很难。有的时候想想,国内国内的程序员心态差异太大了,扯远了。

an interesting new Google Maps feature that animates the static information found in books by organizing a sample of locations from them on an interactive map, with snippets of text from the book, & links to the actual pages where the locations are mentioned. when the automatic techniques determine that there are a good number of quality locations from a book to show you, you'll find a map on the "About this book" page.
(seems to be limited to a few examples only?)

a transformation method of music into an image. colors correspond to harmonic interval values, as a "correspondence of 2 super-harmonious structures: white light & the consonant chord". the diagonal, vertical & horizontal intersections through the rectangle center reflect strong beats. the distance from the center to the rectangle edge reflects the pitch of note. musical notes are transferred to respective paths. there are 12 paths for the octave, according to the number of semitones in the octave.
