您没发现Win后继无力也就才几年光景?Intel的CPU搞不定mobile市场也不过这几年的

思想。不要光看外表看不到本质,这些思想不用Java,换一套别的也能起来。当然

从我的角度看,除非马鬃自己疯了,否则后发者已经机会很小了。哪怕是google和msft
倾力,也不过是争夺老二的位置。就好像,现在不管谁来,在search上都无法撼动
google一样。
马鬃已经建立了完整的ecosystem,这个可不是买个操作系统回来再装软件,现在大家
选择一个云,就必须考虑以后所有的后续研发,所以黏性之大,不下于操作系统,今天
任何没吃错药的普通公司基本上都是选择马鬃(某些有特别需求的文艺公司和2B公司我
就不知道了)。
马鬃的云今天已经self sustainable了,马鬃一年在云上现在营收4B美金,我不知道这
个部分的毛利率多少,但是就凭这个,基本上每家每年都要多掏出2B才能和它打平吧。
所以说这个竞争是完全不公平的,马鬃目前的优势会在未来不断的扩大。最可怕的是,
因为马鬃云的巨大客户群,它对ecosystem的后续投入会立刻转化为更高的营收,提供
更高的黏性,建立更高的bar。比如马鬃今天说它搞个load balancer(当然这个已经有

“界面”这种东西俺确实不屑,也理解别人非常需要,得有。anyway,俺不关心。
clojure为啥没有tail recursion?closure为啥没有continuation?因为closure活在
java机上。所以说clojure没啥意思,甚至多此一举。
c族有多少变种?lisp有多少变种?长命的lisp实现ecosystem都巨大。racket以前叫

c*最重要的是将来如果你要上hadoop的话

都帮你做好了,你可以直接跟hadoop common,yarn这些对接上
毕竟都是一个community里面的东西
如果你用的是其他的话,这都要自己去倒腾
这种不同系统之间的整合最烦了,随便一个不兼容可以让你卡半天
如果是support要钱的话,有些还故意给你下套让你掏钱,日它祖宗
而且support很多p用没有,那些人水平还不如你自己搞,很多时候

产品越多,平台绑定越难。说白了,紧约束的ecosystem设计难度超大。
我最近在研究ecosystem设计的形式理论。可以确切的证明简化模型中,紧约束能成功
的是极少数。能打倒紧约束的扰动,往往只需要很小的“能量”。相比较而言,松约束
的劣势是自身的一致性不强,会导致内爆。
Apple同样也有这个问题.为啥icloud driver那么难用.果粉都没几个能搞清楚policy的.
google driver次之.drop box最好用.我觉得这不是程序员的问题.其实是更高层次的技

标 题: 生物大牛们讨论转基因也是瞎子摸象
发信站: BBS 未名空间站 (Thu Sep 12 10:20:40 2013, 美东)
我承认,证明一个事情不容易,怀疑一个东西却容易的多。
但是,转基因的确有一些生物大牛们不能回答的问题,这些问题在不同层面:
1。很多生物大牛懂得遗传,不懂毒理,不知道为什么转基因要做生殖发育毒性,以为
过敏这样的东西很快就能鉴定,其实不然。或许有些转基因食品对吃者的危害,是造成
下一代更容易过敏。
2。转基因作物的环境影响研究目前不完备,应该研究有些转基因作物能否成为

3。转基因作物对土壤的影响,包括对土壤中细菌结构的影响。你通过转基因压制某些
