Drew Endy taught undergraduate students how to make e. coli bacteria that smelled like wintergreen, using his biobricks. This shows us a future for biology where "useful biological tasks" can be "automated" using "components". The quotes indicate where research and development are going—building components, figuring out how biological amateurs can assemble them, and to what end. The overlap with open source and the low-barrier-to-entry that's reminiscent of the web are particularly interesting to us. Watch list: Drew Endy, George Church, Christina Smolke, Open Wetware, Ginkgo Bioworks. |
上次说到slideshare.net里正在举行一个名字叫做Presentation Design Tennis的活动,每个人提交一个幻灯片,最后组合成一个14个幻灯片的幻灯片作品。小容参与了整个过程,虽然第一张幻灯片被宣布无效,不过,小容却中选了最后一张幻灯片。不过,看起来这个活动并不如预期的火爆,每天参与的人数很少。这反映出Slideshare.net的社区氛围还不是很成熟。
1.
最后的成品如下,这个幻灯片的主题What is community倒是非常应景——最近大陆网络圈子里的SNS社区讨论的话题非常火爆。
在小容看来,这个幻灯片协作活动本身也回答了它自己提出的问题:
• 社区意味着会话——基于了解建立信任
• 社区意味着参与——参与越多收获越多
• 社区意味着规则——共同契约达成秩序
• 社区意味着协作——每个个体彼此信任
• 社区意味着创造——群体智慧解决问题
••••••
拿最近大陆网络圈中讨论热烈的“SNS社区”来和上述的理想境界对比一下,小容感觉,在纷纷扰扰的嘈杂声中,社区俨然浮现出扑朔迷离的幻象。许多讨论缺乏统一的术语界定,语境背景也参差不齐。

其实小容住的地方离太空中心很近,冬天和春天里也经常z在清晨跑步到那里。朋友也经常介绍说太空中心也很精彩,只是小容一直懒惰,许多个周末过去了,依然没有去吃吃窝边草。记得很久很久以前小容是个科幻迷,在初中时看了许多航天科普读物。或许是想着既然住这么近,那么,随时都会有机会来玩。可是日子飞快,一眨眼已经过去两个季节。
上周的时候,女友请了两周假期从纽约过来玩,于是上个周末一起去太空中心。小容这次办理了会员卡,这样倒是以后可以常去了。太空中心和NASA隔着一条马路。太空中心其实就是一个大型的以太空科普为主题的展览馆和游览场,有航天航空实物、科普图片展览、电视纪录片、电影院、航天飞机模拟控制游戏,还有太空生活模拟真人表演。此外,还有让小孩玩得不亦乐乎的冒险娱乐城。当然,还少不了餐厅和纪念品商店:)
上午的时候我们在太空中心里逐个项目欣赏,下午就从太空中心做游览车穿过马路下面的短短的隧道,到NASA游览了一圈,这圈旅程实际上就是在NASA里转了一大圈,途中逗留两站,一站是在火箭发射控制室听讲解,另一站是参观火箭公园,有硕大无比的火箭实物。小容这次不仅拍了相片,而且拍了视频。NASA游览的过程只有视频,没有照片。(网络上找到其他人的游记,请看这里)
下面先分享几张照片,更多照片已经分享在Flickr上,请看这里。视频需要等待一些时日。

在游览了太空中心后,某日发现Google的主页变成航天图案,原来是纪念NASA成立50周年。
小容很喜欢NASA成立50周年的标志。这里是NASA成立50周年的专题网站。
NASA制作了许多网站,并为互联网贡献了许多宝贵的资料。对比庞大的经费预算,NASA所做的一些面向公众的公关宣传活动和信息开放看起来就很正常。
这是NASA设立的图片网站,有兴趣的朋友可以在这里搜索图片,了解太外空的秘密。

上次小容去纽约的时候,女友就说想要做提拉米苏,这次她过来之后,我们买了材料和器具,经过不懈的努力,终于做出一个看起来很像样的提拉米苏。
小容把这个提拉米苏改名为德拉米苏。据说提拉米苏的意思上“带我走”,各位读者看到这里,请动动脑筋帮助小容想想德拉米苏的含义。
前文回顾:
I did not usually go to “Elite” servers on Dell web site but looking at customers system today I went to check Dell Poweredge R900. This monster takes up to 4 Quad Core CPUs and has 32 memory slots, which allows to get 128GB of memory with 4GB of memory chips. This means upgrade to default configuration to 128GB of memory will cost you just $9600 (list price). I’ve been able to configure on a web the system with 8*2.5″ hard drives RAID and 2 CPUs (just as we usually configure PowerEdge 2950) with 128GB of RAM for about $16000. This means talking to Dell Sales rep it can purchases within $15000. This may sounds as a lot but if you’re memory constrained it is cheaper per GB than buying 32GB box for $6000
So am I scale-up advocate ? No. But it is quite frequently systems are designed to have “working set to fit in memory” to perform well and such systems can avoid good consolidation factor for such application, or would allow them to delay sharding.
This box also has 4 CPU sockets which means 16 fast cores and 128GB of memory becomes commodity - Quite a challenge for MySQL to take
I have not had a chance to play with such box myself besides couple of customer production installations but it looks pretty sweet.

有句话这样说,zsh: The last shell you’ll ever need! Z是最后一个字母,所以是终极Shell。
我曾经搜索到一个比较各种Shell的文章,Zsh交互性是A+级别的,远高于其它Shell。在编程方面,Zsh是A级的吧,也是最高的。只是不知道出于什么原因,Zsh被严重的低估了。

Today FortiusOne announced its acquisition of Mapufacture, the web's original geo-feed aggregator. FortiusOne is the creator of GeoCommons, a geo-data repository with analysis tools (Radar post). This acquisition brings Fortiusone both talent and the technology to handle third-party feeds. Mapufacture was created by Andrew Turner and Mikel Maron, two well-known geohackers. In addition to collaborating on Mapufacture they have also worked on the Mapstraction Javascript library (Radar post) and GeoPress, a mapping plugin for Wordpress blogs (Radar post). Mikel is also known as the creator and champion of GeoRSS. Andrew Turner will be joining the company as CTO. Mikel will become an advisor. At its core Mapufacture is a map making tool. Users can create maps by combining feeds or their own geo data sets. If you're not sure where to find a geofeed check out Platial, Flickr, Yahoo! Pipes or any hosted KML file. The maps can be embedded on third-party sites. Mapufacture also provides timeline tools so that you can see how your data changes over time. GeoCommons first launched at Where 2.0 in 2007. Later that year it went offline for a complete redesign. The company has slowly been releasing pieces of it back out. The first major component out the door is Finder! Finder! lets you search for datasets, bookmark them to your account and download them as KML, ShapeFile or a spreadsheet. You can find datasets of almost any type including some about employment, universities, or the internet. Mapufacture will eventually be merged into GeoCommons; it will become Maker, a portion of GeoCommons that will let you make and share maps. This will complete the relaunch of GeoCommons major features. The importance of geodata often goes unnoticed by people who don't work with it everyday. Until mashups and Google Earth I doubt many people ever gave geodata a second thought. I hope that GeoCommons continues to bridge that gap. GeoCommons is going to provide us with easy-to-use, web-based tools that allow for powerful analysis and a repository of geodata in open formats. Hopefully their tools and data will not go unnoticed. |

ETech's CFP has launched. The theme this year is Living, Reinvented: The Technology of Abundance and Constraints. To that end I spent time with MITs Scratch Team (changing computer education) and the RoboScooter team (changing transportation). We're going to explore the following themes. Make sure that you get your submissions in by September 17th.
But ETech isn’t just about “haves” and “have-nots.” Some people choose to live with constraints within the abundant world. What trends and innovations are emerging?
