大雪下了好几天了,可是温度又不够低,下了化,化了下,倒是很喜欢这纯白的世界,遮掉了一切的丑陋,虽然雪化了之后终究还是要露出真面目。
穿着高帮goretex在路上走路的时候冒出来一个词:雪龙号破冰船。貌似是当年中国最早的到极地考察的破冰船之类的。然后在一次考试中我不小心少写了个冰字,结果是雪龙号破船被大家笑了好长一阵子,哈。
窗外的雪是斜着飘的,煞是凶猛.spotify播放的是stairway to heaven,很喜欢前面那一段的低吟式的淡淡叙述,整首歌非常有层次。庾澄庆有次在康熙唱过这首歌,别的没记住,就记得那句“剩下的歌词我不记得~~”。我是唱不了副歌那一段,唱半首嗓子就废了,但是很喜欢前面主歌的部分。干净的旋律和电琴的配合,如果用尼龙弦伴奏不知道会是什么效果。
昨天第一次从家走到市图, 发现其实只要15分钟就足够了,还锻炼身体,真不错,哈。在路上戴着眼镜儿,忽然发现了很多之前没见过的东西,呵呵。在近视以后,都习惯除了上课之外不戴眼镜儿。生活中看到的东西好像也就一直都很模糊,呵呵。昨天第一次在路上看得那么清晰忽然觉得很奇怪的感觉。
下礼拜的execution的考试混个过就完了,书都还没,实在太贵了,Michael同学看过去挺通情达理的,随便写写应该不会太过分吧,嘻嘻。很有可能是人生最后一个考试了,唔。
刚刚想起来明天就3月了,二月只有短短的28天,上礼拜execution的课有个作业是time journal,做了自己一个礼拜的记录之后统计how much time you devote to the goals. 发现我一个礼拜花在thesis上的时间只有25-30小时,按照800-1000小时的要求我这需要25周才能搞定,进度明显不够快,吓了自己一跳,等第一P这几门课结束了,要集中突击一下了。
IDS报告完成~~
痛苦无比的IDS报告终于完成了。越写越有感觉,哈哈。

这门课虽然很务虚,还是学到了一些宏观理论的,呵呵。宏观理论不仅能帮忙解释或者预测一些技术发展,而且还有很好的唬人效果。昨天耐克的电话面试我就大谈Michael Porter,哈。
明天八点seminar,睡觉睡觉!
雪中KTH
噜噜噜
今天工作了N个小时,刚刚回到家,哈哈哈,自己都觉得很很猛!昨晚也不知道点睡的,大概也得3点了。早上9点一个电话直接叫醒了。一看号码010的,心想貌似北京没什么人会用座机给我打电话,莫非又是什么公司的,信号怒差,听了N次听出来是耐克。N久以前貌似投了个耐克的trainee,姐姐用怒甜无比的声音问我什么时候方便可以安排一次电话面试,约了下礼拜一早上9点,北京时间16点。我记得耐克招聘的网站是一个叫的卢的网站,界面写得很差,load一次等半天,好像材料都没填齐。
前天买了一大包腰果,把饼干盒都装满了,哈哈哈。腰果叫cashew,这个词原来不是很认识,还是在西班牙的餐馆被人教会的。有人要点fried chicken with cashew,菜单上没有,英国人另要的。解释成a special nut looks like kidney, 哈哈哈。才领悟了腰果的腰原来是腰子的腰,雷,哈哈。

Finance for startup 这门课真是越上越有滋味,主要授课老师南方的花本身水平就很好,guest的水平也都非常不错。今天又来了俩VC,一个是government的,主搞生命科学,另一个是私人VC,总金额1.5billion,spotify的主要VC之一。收获良多!
问了几个问题,两个牛人对我印象都还行,嘻嘻。可惜忙着搞论文,business idea只能放一放了,不然就上去找他要个名片哪天要钱去,哈。不过要是哪天真用得到,应该还是能找到。
论文题目改改停停,昨天晚上又读了3篇巨作之后,现在算是找到一个比较确定的方向。IS与SCM,做一个全供应链的模型,结合DW,IS,重点谈谈RFID的作用,用REA分析供应链的各个成分,最后porter的strategy上,找出SCM和IS及RFID的alignment。perfect!!!
Scania有个SOA的论文,貌似还行,但是我好像很喜欢现在这个题目,舍不得放,TAT。在INDEK这边,SCM这个题目貌似也能用,分出一部分来扩展一下应该行。加油加油!!
这两天在练planche, 练得浑身肌肉酸痛,发现原来很多练不到的肌肉planche都可以帮到,第一个阶段还基本没过关,哈哈。David同学已经可以第二阶段10几下了。youtube上的那个大哥的训练视频,实在是太牛了http://www.youtube.com/watch?v=YvbLSgWMJec
VC 算术
I’ve found that even sophisticated entrepreneurs didn’t necessary grasp how valuation math (or “deal algebra”) worked. VCs talk about pre-money, post-money, and share price as though these were universally defined terms that the average American voter would understand. To insure everyone is talking about the same thing, I started passing out this document. Recognize that this is about the math behind the calculations, not the philosophy of valuation (which Fred’s blog addresses).
In a venture capital investment, the terminology and mathematics can seem confusing at first, particularly given that the investors are able to calculate the relevant numbers in their heads. The concepts are actually not complicated, and with a few simple algebraic tips you will be able to do the math in your head as well, leading to more effective negotiation.
The essence of a venture capital transaction is that the investor puts cash in the company in return for newly-issued shares in the company. The state of affairs immediately prior to the transaction is referred to as “pre-money,” and immediately after the transaction “post-money.”
The value of the whole company before the transaction, called the “pre-money valuation” (and similar to a market capitalization) is just the share price times the number of shares outstanding before the transaction:
Pre-money Valuation = Share Price * Pre-money Shares
The total amount invested is just the share price times the number of shares purchased:
Investment = Share Price * Shares Issued
Unlike when you buy publicly traded shares, however, the shares purchased in a venture capital investment are new shares, leading to a change in the number of shares outstanding:
Post-money Shares = Pre-money Shares + Shares Issued
And because the only immediate effect of the transaction on the value of the company is to increase the amount of cash it has, the valuation after the transaction is just increased by the amount of that cash:
Post-money Valuation = Pre-money Valuation + Investment
The portion of the company owned by the investors after the deal will just be the number of shares they purchased divided by the total shares outstanding:
Fraction Owned = Shares Issued /Post-money Shares
Using some simple algebra (substitute from the earlier equations), we find out that there is another way to view this:
Fraction Owned = Investment / Post-money Valuation = Investment / (Pre-money Valuation + Investment)
So when an investor proposes an investment of $2 million at $3 million “pre” (short for premoney valuation), this means that the investors will own 40% of the company after the transaction:
$2m / ($3m + $2m) = 2/5 = 40%
And if you have 1.5 million shares outstanding prior to the investment, you can calculate the price per share:
Share Price = Pre-money Valuation / Pre-money Shares = $3m / 1.5m = $2.00
As well as the number of shares issued:
Shares Issued = Investment /Share Price = $2m / $2.00 = 1m
The key trick to remember is that share price is easier to calculate with pre-money numbers, and fraction of ownership is easier to calculate with post-money numbers; you switch back and forth by adding or subtracting the amount of the investment. It is also important to note that the share price is the same before and after the deal, which can also be shown with some simple algebraic manipulations.

IDS之硬盘发展史,dilemma of innovation
Industrial dynamic 马上就要最后一个senimar了,都说比较扯,其实还是学到点儿东西的,看问题的角度要足够全面广泛还要有一定的高度才能总结出那些东西。Hughes Thomas. Kline, Rosenberg, Eric Dahmen, Michael porter, Mashall, 都是宗师级的人物,呵呵。最新读的一篇文章是讲硬盘的演进史并结合分析其中的商业循环。历数从14英寸时代一直到1.8寸,中间经历了8,5.25,3.5,2.5,等众多时代。而每一次的历史轮回都是如此的相似。在每次的更新换代中,总有一些公司倒下,而每次倒下的原因总是相同的,呵呵。
1978年以前,市场基本是14英寸盘的天下,到1978年,几家公司开始生产八寸盘,有Micropolis,Quantum,Shugart Associates等。当时的市场情况是8寸盘只能生产到上限40兆的容量,而当时的主要市场—大型机(mainframe)的需求是300-400兆的容量,新的8寸盘对于他们来说没什么用处,即满足不了需求而且还比14寸更贵,另外体积小对于大型机影响也不大。于是14寸盘的供应商们在他们的大客户的反馈一家下,做出了战略决定是做好14寸就行。
然而被忽略的是小型机(minicomputer)市场的发展,这个时期的小型机生产商大多也是新公司(startups), 其中的代表就是Hewleet Packard,估计很多人不知道这是什么,这就是HP,哈哈,惠普同学。技术上看,小型机的硬盘容量需求不用那么大,8寸盘能提供的40兆基本够用,在价格稍高的情况下,小型机的产商们愿意付钱购买尺寸更小的硬盘。于是8存盘占领了新的小型机市场。当14寸盘产商意识到这个问题的时候,两三年已经过去了,这一轮更新的结果是,原来硬盘界的大牛,14寸盘的产商们,几乎全死光了。
到后来几轮更新换代,相同的故事一直在发生着,8寸盘的产商们倒在了5.25的新产商脚下,5.25寸盘产商又大部分倒在3.5寸盘脚下。历史一直在重复,而人们却总是缺乏足够的警觉性。这中间有个比较例外的是Seagate,就是大名鼎鼎的希捷硬盘,应该也是由于时机好一下,初次进入市场是5.25寸,吸取了前两轮更新的教训,在3.5寸盘初现的时候,研发的力量基本有跟上,1984年Rodime作出3.5寸盘,希捷在1985年就跟进并作出prototype并交付IBM测试使用,结果不出意外,IBM对此产品根本不感兴趣,因为他们正准备新一轮的计算机升级,需要40-60兆的硬盘,而当时的3.5寸盘只能做到20兆的容量。对于市场的冷淡回应,高层又降低了对3.5寸盘市场的预期,最终决策层决定取消3.5寸盘的上市。他们的理由很简单:5.25寸的市场要大得多,把研发精力投入到5.25盘的容量升级要比开发的3.5寸市场带来更对的revenue。当然,害怕挤占本公司同类产品的市场也是新技术推迟的一个重要原因。希捷比较幸运的是后来比较顺利的转轨生产3.5寸盘于是成了今天的领头羊。可是过去几年希捷一直被人说就台式机硬盘好估计很大原因也是这个技术的升级吧,哈哈。
同样的故事发生在很多其他的行业,想当年90年代大陆的通信市场传呼机、大哥大清一色摩托罗拉的市场,可是moto死守自己很牛逼的第一代模拟通信市场,最后的下场也很惨淡。
回头看这些历史的时候总觉得前人很没眼光,可是想想我们现在所处的年代,又有谁能作出准确的预测,1.8寸盘的市场回事如何,如果你是公司的决策者,该如何做决断,很难,呵呵!
