April 23 z.t: 狗认同了鸭,坚持的力量前几天,一名记者在网上发了一则消息:一对英国夫妇养了一只“迷糊”鸭子,它以为自己是条狗,并在主人遛狗的时候形影不离。现在,它终于被家里的两条宠物狗所接纳,每天都会一同外出散步。这在当地形成了一道颇为有趣的风景。 主网站URL: http://vincentyang.cn/blogs/vincentyang/archive/2009/04/23/z-t.aspx April 22 低烧呓语好久没病了,有点小病就倒了。也没多大的事,就是怕传染给别人。没去天津做项目,就老老实实在床上,脑子却不老实。仿佛是温度高点,车的引擎还转得快。把最近的一些杂乱的笔记,胡乱的说一下:
这一段学到的最重要的是李宗南老师的告诫:每次会议或接触后,要有Follow-up,thank you letter,非常重要的习惯,我非常欠缺!今后重点提高! 另:这个贴真乱,人没大病(低烧,不用担心);是脑子有点忙,顶多属于精神范畴的病吧,别怕。呵呵。 主网站URL:http://vincentyang.cn/blogs/vincentyang/archive/2009/04/22/788.aspx April 19 更正消息:上周五只有三个到职。有必要更正一下,上周五只有三位到职,不是上周说的四位。有一位被人抢走了。而且是被做外包的公司抢走了。在这种经济环境中,外包公司居然比我们公司有前景,有吸引力,“很没面子”到了无语的地步。不过这非常正常,创业公司开始,一切还是画的大饼,我也没实力和人拼薪酬。所以我只简单的回这位同学一条短信:“OK,Best Wishes.” 以后,这种事还是不要太早说,一切没发生的,都有可能变。但在这,还是要更正一下,要不“吹牛”就变“撒谎”了。(上次其实是挺激动、挺感激,才在博客里记录感谢一下,只是太早了点)。 这样,我们又有一个Headcount,如果你们有推荐,我们还有兴趣。。。 主网站URL:http://vincentyang.cn/blogs/vincentyang/archive/2009/04/19/783.aspx April 13 转:郎咸平:中国企业存在病态心理http://www.jsmedia.tv/bbs/viewthread.php?tid=44406&extra=page%3D1 我在全中国各在演讲,西到乌鲁木齐,北到内蒙,东到丹东,南到三亚,我走到任何一个地方,企业家问我问题之类似让我感到震惊。他们问:郎教授,你能不能谈一下,哪一个行业是最有潜力的, 我想去投资。地方干部也会问我一个问题:郎教授能不能请你谈一下我们这个区域的区域竞争优势。他们问的这些问题都是错的,问这些问题的原因就是僵化思维,企业家也是这么想问题的。我现在就想从中华文化来谈谈,什么是中华文化的本质。 主网站 URL: http://vincentyang.cn/blogs/vincentyang/archive/2009/04/13/775.aspx April 12 转:郭台铭说..................转自:http://www.rfidworld.com.cn/bbs/Read-b11-t15988.htm 各位: 2009-4-11:感恩经过一个多月的招聘,我们终于确认了三个非常好的人选。因为预算计划只有两个空缺职位,实在难以取舍。因而特别内部讨论两天。最终发现我的团队比我还贪心,成功地“忽悠”了我,决定都要!这样加上原来的同事,同事的推荐,公司已到了10人。4-5个月达到我要“严格控制的一年计划规模”;而且都是“白骨精”,原预算也不得不提高。不得不说我们团队信心好像不比我小,但换来的实力可以说是值得骄傲的! 昨天,原来跟了我多年的Levi,正式从微软离职。今天,三位人选都在24小时内接受了我们的Offers。下周,他们都能开始到岗,开始工作。 2009年4月11日,我非常激动,更加感恩:谢谢你们四位,也谢谢现在团队里的每一个人! 主站点URL:http://vincentyang.cn/blogs/vincentyang/archive/2009/04/12/2009-4-11.aspx April 11 转:为什么坏同学都当了老板?http://www.rfidworld.com.cn/bbs/Read-b11-t16882.htm 一次回老家与几位小学同学相聚,“忆往昔”之后,聊起了其他人现在的情况。谢老大自己办工厂,资产几百万元;大王二当包工头,在县城买了几套房;杨拐子从卖盒饭起家,如今在城里盘下两家大酒店;小王二靠跑运输起家,发展到拥有60多台大小车辆的运输公司。大家纷纷感慨:想当年,他们还抄我们的试卷,如今却个个都当老板。而我们这些当初成绩优异的好学生,多半拿着死工资,境遇一般。 为什么坏同学都当了老板?仔细琢磨了一阵子,我逐渐瞧出了点儿门道。
我的回帖: 非常有意思。收藏了。

As good design cannot be measured in a finite way he set about expressing the ten most important criteria for what he considered was good design. Subsequently they have become known as the ‘Ten commandments’. Here they are. Vitsœ’s designer Dieter Rams. Good design is innovative It does not copy existing product forms, nor does it produce any kind of novelty for the sake of it. The essence of innovation must be clearly seen in all functions of a product. The possibilities in this respect are by no means exhausted. Technological development keeps offering new chances for innovative solutions. TP 1 radio/phono combination, 1959, by Dieter Rams for Braun Good design makes a product useful A product is bought in order to be used. It must serve a defined purpose – in both primary and additional functions. The most important task of design is to optimise the utility of a product. MPZ 21 multipress citrus juicer, 1972, by Dieter Rams and Jürgen Greubel for Braun Good design is aesthetic The aesthetic quality of a product – and the fascination it inspires – is an integral part of its utility. Without doubt, it is uncomfortable and tiring to have to put up with products that are confusing, that get on your nerves, that you are unable to relate to. However, it has always been a hard task to argue about aesthetic quality, for two reasons. Firstly, it is difficult to talk about anything visual, since words have a different meaning for different people. Secondly, aesthetic quality deals with details, subtle shades, harmony and the equilibrium of a whole variety of visual elements. A good eye is required, schooled by years and years of experience, in order to be able to draw the right conclusion. RT 20 tischsuper radio, 1961, by Dieter Rams for Braun Good design helps a product to be understood It clarifies the structure of the product. Better still, it can make the product talk. At best, it is self-explanatory and saves you the long, tedious perusal of the operating manual. T 1000 world receiver, 1963, by Dieter Rams for Braun Dieter Rams on T 1000 Dieter Rams talks about his design for the Braun T 1000 radio Good design is unobtrusive Products that satisfy this criterion are tools. They are neither decorative objects nor works of art. Their design should therefore be both neutral and restrained leaving room for the user’s self-expression. Cylindric T 2 lighter, 1968, by Dieter Rams for Braun Good design is honest An honestly-designed product must not claim features – more innovative, more efficient, of higher value – it does not have. It must not influence or manipulate buyers and users. Wall mounted Audio 2/3 (Components: control TS 45, reel-to-reel tape deck TG 60, slim speakers L 450, record player PCS 5), 1962/1962, by Dieter Rams for Braun Good design is durable It is nothing trendy that might be out-of-date tomorrow. This is one of the major differences between well-designed products and trivial objects for a waste-producing society. Waste must no longer be tolerated. See more of 606 Universal Shelving System 606 Universal Shelving System, 1960, by Dieter Rams for Vitsœ Things which are different in order simply to be different are seldom better, but that which is made to be better is almost always different. Dieter Rams, 1993 My goal is to omit everything superfluous so that the essential is shown to best possible advantage. Dieter Rams, 1980 Good design is thorough to the last detail Thoroughness and accuracy of design are synonymous with the product and its functions, as seen through the eyes of the user. World traveller ET 88 calculator, 1987, by Dietrich Lubs for Braun Good design is concerned with the environment Design must contribute towards a stable environment and a sensible use of raw materials. This means considering not only actual pollution, but also the visual pollution and destruction of our environment. 850 Conference table, 1985, by Dieter Rams for Vitsœ.

Google for the first time showed off its server design. (Click to enlarge) (Credit: Stephen Shankland/CNET) Updated at 4:08 PDT with further details about Google's data center efficiency and shipping containers modules. MOUNTAIN VIEW, Calif.--Google is tight-lipped about its computing operations, but the company for the first time on Wednesday revealed the hardware at the core of its Internet might at a conference here about the increasingly prominent issue of data center efficiency. Most companies buy servers from the likes of Dell, Hewlett-Packard, IBM, or Sun Microsystems. But Google, which has hundreds of thousands of servers and considers running them part of its core expertise, designs and builds its own. Ben Jai, who designed many of Google's servers, unveiled a modern Google server before the hungry eyes of a technically sophisticated audience.
Google server designer Ben Jai (Credit: Stephen Shankland/CNET) Google's big surprise: each server has its own 12-volt battery to supply power if there's a problem with the main source of electricity. The company also revealed for the first time that since 2005, its data centers have been composed of standard shipping containers--each with 1,160 servers and a power consumption that can reach 250 kilowatts. It may sound geeky, but a number of attendees--the kind of folks who run data centers packed with thousands of servers for a living--were surprised not only by Google's built-in battery approach, but by the fact that the company has kept it secret for years. Jai said in an interview that Google has been using the design since 2005 and now is in its sixth or seventh generation of design. "It was our Manhattan Project," Jai said of the design. Google has an obsessive focus on energy efficiency and now is sharing more of its experience with the world. With the recession pressuring operations budgets, environmental concerns waxing, and energy prices and constraints increasing, the time is ripe for Google to do more efficiency evangelism, said Urs Hoelzle, Google's vice president of operations. "There wasn't much benefit in trying to preach if people weren't interested in it," said Hoelzle, but now attitudes have changed. The company also focuses on data center issues such as power distribution, cooling, and ensuring hot and cool air don't intermingle, said Chris Malone, who's involved in the data center design and efficiency measurement. Google's data centers now have reached efficiency levels that the Environmental Protection Agency hopes will be attainable in 2011 using advanced technology. "We've achieved this now by application of best practices and some innovations--nothing really inaccessible to the rest of the market," Malone said.

Typical data centers rely on large, centralized machines called uninterruptible power supplies (UPS)--essentially giant batteries that kick in when the main supply fails and before generators have time to kick in. Building the power supply into the server is cheaper and means costs are matched directly to the number of servers, Jai said. "This is much cheaper than huge centralized UPS," he said. "Therefore no wasted capacity." Efficiency is another financial factor. Large UPSs can reach 92 to 95 percent efficiency, meaning that a large amount of power is squandered. The server-mounted batteries do better, Jai said: "We were able to measure our actual usage to greater than 99.9 percent efficiency."
Urs Hoelzle, Google's vice president of operations (Credit: Stephen Shankland/CNET) The Google server was 3.5 inches thick--2U, or 2 rack units, in data center parlance. It had two processors, two hard drives, and eight memory slots mounted on a motherboard built by Gigabyte. Google uses x86 processors from both AMD and Intel, Jai said, and Google uses the battery design on its network equipment, too. Efficiency is important not just because improving it cuts power consumption costs, but also because inefficiencies typically produce waste heat that requires yet more expense in cooling. Costs add up Jai has borne a lot of the burden himself. He was the only electrical engineer on the server design job from 2003 to 2005, he said. "I worked 14-hour days for two and a half years," he said, before more employees were hired to share the work. Google has patents on the built-in battery design, "but I think we'd be willing to license them to vendors," Hoelzle said. Another illustration of Google's obsession with efficiency comes through power supply design. Power supplies convert conventional AC (alternating current--what you get from a wall socket) electricity into the DC (direct current--what you get from a battery) electricity, and typical power supplies provide computers with both 5-volt and 12-volt DC power. Google's designs supply only 12-volt power, with the necessary conversions taking place on the motherboard.
Google's data center efficiency has been improving gradually. (Credit: Stephen Shankland/CNET) That adds $1 or $2 to the cost of the motherboard, but it's worth it not just because the power supply is cheaper, but because the power supply can be run closer to its peak capacity, which means it runs much more efficiently. Google even pays attention to the greater efficiency of transmitting power over copper wires at 12 volts compared to 5 volts. Google also revealed new performance results for data center energy efficiency measured by a standard called power usage effectiveness. PUE, developed by a consortium called the Green Grid, measures how much power goes directly to computing compared to ancillary services such as lighting and cooling. A perfect score of 1 means no power goes to the extra costs; 1.5 means that half the power goes to ancillary services. Google's PUE scores are enviably low, but the company is working to lower them further. In the third quarter of 2008, Google's PUE was 1.21, but it dropped to 1.20 for the fourth quarter and to 1.19 for the third quarter of 2009 through March 15, Malone said. Older Google facilities generally have higher PUEs, he said; the best has a score of 1.12. When the weather gets warmer, Google notices is that it's harder to keep servers cool.
An excerpt from a video tour Google presented of its data center containers. Like conventional data centers, Google's shipping containers have raised floors. (Credit: Stephen Shankland/CNET) Shipping containers Modular data centers are not unique to Google; Sun Microsystems and Rackable Systems both sell them. But Google started using them in 2005. Google's first experiments had some rough patches, though, Clidaras said--for example when they found the first crane they used wasn't big enough to actually lift one. Overall, Google's choices have been driven by a broad analysis on cost that encompasses software, hardware, and facilities. "Early on, there was an emphasis on the dollar per (search) query," Hoelzle said. "We were forced to focus. Revenue per query is very low." Mainstream servers with x86 processors were the only option, he added. "Ten years ago...it was clear the only way to make (search) work as free product was to run on relatively cheap hardware. You can't run it on a mainframe. The margins just don't work out," he said. Operating at Google's scale has its challenges, but it also has its silver linings. For example, a given investment on research can be applied to a larger amount of infrastructure, yielding return faster, Hoelzle said.
