As I wrote last week, Hillary Clinton is probably going to become the next
president. But there’s an awful lot of room to debate what “probably”
means.
FiveThirtyEight’s polls-only model puts Clinton’s chances at 85 percent,
while our polls-plus model has her at 83 percent. Those odds have been
pretty steady over the past week or two, although if you squint you can see

来自主题: Stock版 - 凑热闹说说Model 3
我已经定了model 3。我来简单说两句model 3的问题:
1)profitability: 均价10万的model S毛利率不到25%,也就是说成本要达到7.5万
。model 3物理尺寸和里程也就是小20%,再加上scale of economy,成本递减40%。
那么也得要有4.5万的成本,算均价5万,最多就是10%的毛利。这个毛利率不能支持太
高的multiple;
2)business model: 目前特斯拉自建supercharger, store, service center。这个
business model 能不能适应几十万上百万的model 3交货量?也就是说model 3量产上
市后,这些基础设施投资会是目前的10倍几十倍的增长。作为一个重资产的startup
公司,核心汽车领域的研发生产已经非常消耗资金了,完全没有必要继续负担基础设施
的建设。如果这个business model 不能改变,会成为发展的瓶颈。
以上还是远期的问题。Hype过后,下面几个月,最直接的问题就是,model S的销

上周发布会刚刚结束的时候, Model 3 的预售量就已经突破了 12.5 万。据特斯拉
CEO 埃隆·马斯克透露,截至 4 月 2 日,Model3 的订单数量已经达到 27.6 万辆,
超过了特斯拉目前为止的全部销量总和。特斯拉的股价也受此提振不断高涨,创下去年
10 月以来的新高。
Model 3 大热的背后,让人又不免开始担心 Model 3 生产的方方面面自建工厂是否能
顶得住产能压力?尚未确定的交付日期是否会遥遥无期?同样,很多人也不理解特斯拉
为什么坚持自建工厂,而不是全球制造。
当我们回顾特斯拉的诞生时,曾描述过 Roadster 的量产是怎样一种噩梦——车身面板
由法国制造,发动机则由中国台湾制造,在中国大陆购买的单块电池,运到泰国组装成
电池组,然后在最短的时间内送到英国去清关,以防它们降解。整车在英国组装好后,
经由好望角运至洛杉矶。当时,特斯拉最年轻有活力的一群工程师深陷泰国,督促供应
商给生产电池组的厂棚加上一圈墙壁。
从变速齿轮到挡风玻璃,事实一再证明,特斯拉这种硅谷初创公司即使找到了顶级供应
商,也得不到他们最好的团队的支持,即使特斯拉再有雄心魄力,也很难... 阅读全帖

虽然 model 3 车子小,比model S/X 便宜,但是电动车核心技术和很多设计比现在 的
modelS/X 领先一代:
1. 电池包2170的能量密度超过 model s 18650 30%。 另外, 成本大大降低,因为钴%
已经低于5%,未来5个月-一年要实现完全没有钴。 下一代model SX 很快采用新技术
, 马上要推出130 度电电池包。
2。逆变器全部采用sic 技术,虽成本较高(每个die 本身成本增加),但是因为效率
提高~1.2%,导热性能极大提高,耐高温,电池里程提高的电池成本节省可以抵消逆变
器成本增加。 实话实说,model S 本身逆变器技术就已经行业大幅领先,主要是自
己封装技术远远超过其他公司,包括英飞凌(特斯拉10几人团队干翻 英飞凌200 多人
团队)。 其他公司目前不能赶上model S的技术,更不用说model 3.

没有什么学习材料,我觉得目前这块还处于扯蛋的地步
所谓model就是数据结构的抽象,data model就是抽象结构化的数据结构
稍微不同于本科数据结构课程里面学的list, set,map那些
这种数据结构一般是硬盘上的数据结构
modeling就是通过一个抽象化过程把model给建立起来
然后所有的数据都能够通过这种model来存放
db就是这种玩意下的产物,先建一个schema,然后根据schema这个结构
来实现具体的table,来存放具体的数据,里面有pk,fk这些东西
however

现在都在挖掘,如何从无结构或者说很少的结构中抽取出你想要的结果

知识点有很大一部分是是关于这个的技术,比如tf idf这些

来自主题: Stock版 - 凑热闹说说Model 3
本来不打算说什么的。不过既然这两天这么热闹,就跟风揣测一下未
来。
1. 35,000的价格是否合理?
如果Musk承诺的功能都能实现的话,那这个价格算是童叟无欺,是有
竞争力的,即便没有tax credit。
别的不说,乞丐版0-60mph加速时间6秒,这比BBA毫不逊色。更是秒杀
dfbb和一切电动车。
2. 眼下的预定量究竟有多少能兑现?
毫无疑问目前23万的预定量还会持续攀升。等量产开始的时候达到50万
应该一点也不算稀奇。
假设其中一半的预定来自美国,而美国一半的预定会因为tax credit
phase out或用完而取消,那么也只是十几万的影响。再保守些,算
国际订单也取消一半,那最终还是会有25万辆的订单进入生产交付。
后续的销量则会取决于市场对实际产品的反应。
换个角度看,能放心交一千块给tesla两年的,就算不是铁杆粉丝,至
少也是认真想拥有一辆tesla的人。而且人都有从众和争先恐后的心理。
如果到时真车水平达到消费者期望的话,那已经在排队的人恐怕更不愿
意放弃自己的位置。就算自己改变了注意,大概最多也就是转让给亲
戚朋友。
3. tesla真的能把成本降到那么低... 阅读全帖

标 题: 对比bmw 328i,model 3驾驶感受
发信站: BBS 未名空间站 (Sun Aug 19 16:24:54 2018, 美东)
之前一直开的是E92平台的bmw 328i,开了几十mile model 3,对比谈谈驾驶感受
感觉model 3对比328i最大的不同就是平稳,model 3 实在太平稳了,不管怎么快速转
弯,车身都保持很平稳,这点328赶不上,328 在高速度快速转向,车身会有明显倾斜
,但是是那种很自信可控的倾斜。这可能是因为很重的电池放在地盘上造成车身中心很
低并且前后重量平衡。 急转弯能力model 3接近328i,差别微小。高速上弯道操控性和
328差不多,在很高的速度都很轻松自信顺畅,但是model 3的车身倾斜非常明显要比
328i小非常多,这方面差别很大。在高速上model 3更显平稳,车身颤动非常少,这对
于乘客感受明显,在快速驾驶情况下,乘客在model 3要舒适很多。
对于加速,我看表盘和周围... 阅读全帖
