记不清这是第几个了。 LinuxDevices消息Cellphone giants unveil mobile Linux foundation。25号,几家最大的通信技术公司正式成立了一个旨在创建common的移动Linux软件平台的非赢利性组织,LiMo Foundation。发起成员是Moto,NEC,NTT DoCoMo,Panasonic Mobile Communication,Samsung Electronics还有Vodafone。 去年年中是LiMo初露端倪的时候,那时这个组织的名字和目标还有点神秘。据称在量产Linux手机出货量上,全球从高到底顺序是,Moto,Panasonic,NEC,Samsung。如果属实的话,LiMo貌似具备统一mobile Linux平台的能力。 LiMo宣称的目标是,创建”适用于移动设备的,世界上第一个具备全球竞争力的,基于Linux的软件平台”。为达到这一目标,他们会定义: API spec架构open source的参考代码由成员贡献的源码级的组件参考实现使用到的第三方软件的spec 非常high level的技术开发计划已经发布,5页的paper包括了工作范围描述。 老实话说,看上去实在没不出什么新意,所谓architecture,特别是来自联盟类组织的architecture,都是妥协的产物,当然,希望这些都是”伟大的妥协”。 LiMo成员会贡献上图中绿色所示的组件代码。 Paper中除了简略描述了上面那些组件的定义外,还提到了可能会被纳入的已有的open source产品,比如GTK+可能会用于UI Framework。 用最简单的术语说,LiMo会发布定义了common的,low level的Linux操作系统的spec。还会提供测试集帮助制造商验证产品对spec的符合性。符合者可以使用LiMo的logo。 从法律角度看,LiMo的API对成员可以royalty free的使用,他们享受Foundation Public License。Kernel和其他中间件等本来就有的,如果采用GPL,那自然仍是GPL覆盖范围内。非LiMo成员的第三方开发者需要按Foundation API许可使用LiMo定义的API,头文件则要用Object Code License。FPL有类似GPL的地方,比如要求所有改动要原封不动地contribute回给所有LiMo成员,同时,FPL禁止将source code发对非LiMo成员――比如上面说的第三方开发者。这还没完,FPL有两个variant,一个是包含了专利和版权的,LiMo管理的common core 的组件需要这种license;第二种就是仅有版权的FPL,非common core 可以选用这种license,通过这种license,LiMo成员可以互相授权专利技术。Foundation API和Object Code License 没有提及,听上去是个很悲伤的名字,从FPL的描述推断起来,这后两个license更够呛。 这种license设计看上去超级没脑子的样子,写spec的无论组织还是人,没哪个不想自己的条条框框能被广泛接受的,授权条款大多宽松,鼓励人使用。不知是不是电信行业出身的家伙肚子里天生有邪恶的种子。 Open source或者Linux,在这儿也就那么一幌子而已。 LiMo的Founder级成员资格已经不再授予,Core和Associate级别的当然还在open啦。情况是: Founder:第一年年费80万美元;5年后回归Core级别;可以任命executive,architecture,和requirements councils的代表;可以访问,修改foundation code,可以发布基于foundation code 的商业产品 Core:第一年40万美元;可以参与所有council;可以领导working group;可以访问,修改foundation code,可以发布基于foundation code 的商业产品 Associate:第一年4万;可以参与council和working group;只能访问和修改foundation code,不能发布机遇其code的商业产品 看上去在Linux手机圈儿里混的流氓,无论大小,个个都想在标准化工作上插一脚。LiMo的目标一点都不新鲜,此前已经有类似的组织和活动: Trolltech的GreenSuite;买了PalmSource的Access的Access Linux Platform(ALP)(介绍1,介绍2),open source的Hiker Application Framework;OSDL――哦,改名儿了,现在叫Linux Foundation――的Mobile Linux Initiative,目前主要focus在kernel level上;Linux Phone Standards [...]

Source favicon19:44 FreeNAS 当选 SourceForge 月度项目 » DBA notes

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。

FreeNAS.png


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。

googlebooksmap.jpg
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?)

Source favicon04:30 Find and compare local businesses » Official Google Blog


Many people come to Google.com to navigate the web, but are you aware that you can use it to navigate the real world as well? Over the past few months, we've been hard at work making it easier to find and compare local businesses and services right from the standard web results page. Here's what we've come up with:
From now on, you'll see this every time you search for a place, business, or other local information. In addition to providing the basic contact information and map locations for several choices at the top of the page, we also show ratings and provide one-click access to reviews on the search results page so that you can make more informed decisions about where you want to go.

Here are a few specific examples of how you can use Google to search and compare local businesses and services.

We're really excited to offer this easier access to qualitative information about local spots. We find the reviews and ratings generated by others in the know to be quite useful when we want to head to a restaurant, catch a movie, or stay at a hotel -- and we hope you will too.
Source favicon00:15 SMS on orkut » Official Google Blog


While orkut users love having an online social network, we understand that a good deal of your social life happens offline. We wanted orkut to enrich the offline social life of its members, so we thought we could either give you computers with really long cords or we could bring orkut to the device you carry around in your pocket: the mobile phone. Thus the idea for an orkut SMS service was born.

With orkut's new SMS feature, you can scrap your friends, look up their contact information and receive scrap notifications. Now you can send scraps from the bus, bar or bathroom, and your friends can get notified of those scraps when on bicycle, beach or bed. Along with the standard orkut features, we've included a few hidden goodies for the adventurous to find.

This week, orkut SMS will become available to orkut members in Brazil who use Claro as their mobile service provider. When the feature becomes available to you, a message will be displayed when you sign in to your account. We hope to expand soon to other mobile service providers in Brazil and around the globe.

So next time you want to scrap your friend Sergio about a party, just text message orkut with "scrap Sergio it's party time man!"
