是寄I-129F申请表的时候连同寄上还是等签证中心通知收到表以后再寄?
还有各自陈述双方怎样认识的信如果对方英文不好可以用中文写吗?
谢谢!

大概09-10年跳startup的, 有六分之五原地踏步, 六分之一有了一到三米的equity
。 当然还有现在还没ipo的。 回报和跳的时间关系不大,和跳的公司大小关系也不大
, 和水平有一定的关系。 基本上发展好的都是能力情商原来就冒尖的,能力情商高的
也不一定发展的好, 有几个同事去了zynga, groupon就白忙了 。 去linkedin,
facebook的就开心了。跳A B round startup的相对少, fail的可能性也更大。
如果简单的用回报乘以风险,pre-ipo然后股票又在ipo以后涨了是最赚的。 问题是你
不知道上市以后公司股票会怎么走。。。如果你知道不如直接去买股票了。每个人的情
况不一样, 面临的选择也不一样。 这一轮泡泡估计还有一年, 然后象01年, 08年
那样垮下来。我感觉要套现也要抓紧了。

我现在的蛋白是个his-tagged homo dimer,我想把 WT 和 active-site mutant 放在
一起组成一个heterodimer.
请问大虾有没有什么好的办法能够得到这样一个homogeneous population 的
heterodimer ?

理论上可以这样:
构建两个带有不同purification tags而且可以相容的载体,如6xHis tag on pET和
Strep tag on p15A or dual vector。让这两个monomer coexpress,用Ni-NTA和Strep
tag的亲和柱顺序纯化即可。

谢谢楼上的。
我的这个蛋白WT和active-site mutant都是homo-dimer,这样的两个载体co-express能
得到heterodimer吗?会不会只能得两种homodimer?还是两种homodimer加上
heterodimer(minor species)?

exactly, 不是it泡沫,而是创投泡沫,
这一轮疯狂地VC投资风潮很大一部分是美国的QE和利率政策导致的,有大量的闲置资本
在追逐可怜的一点return。
不过现在看来,利率还会长期低迷,所以创投泡沫破灭的时间可能会比我们预期的晚。

I am not talking about new grads. I am talking about senior engineers with
10 yrs experience. Regardless, Twitter got 3-4 folds up 6 months after IPO.
That's the kind of pre-ipo companies you want to chase. Low risk, high award
. It can be a hit and miss, and most won't get that kind of return. But you
can always jump after one year. Compared to early startup, the chance to get
IPO or a material acquisition is remote. That's the point I am trying to
make.

70k RSU package is total bullsxxx, if you are talking about Director
or above position that's a maybe, most common package was 10-15k RSU
for a Sr. level position. Keep in mind IRS & California automatically
took 48% when your RSU vest. A 15k RSU package ends up with $300k after
tax money with 4 years vesting period.

That's a package preipo, not a package now. $800K RSU over 4 years is not
bullshit. That gives you a package of 400k a year with salary. Good enough
to attract engineers from flg. Airbnb and Uber also give that kind of
package today.

Twitter was worth about $16 in secondary market before it filed IPO, and not
without risk (see FB IPO). If you
think 15K shares or $60K/year will help you compete with FLG for seniors,
think
again.

Did you get an offer that prints 70k RSU shares on it from Twitter?

70k shares RSU is definitely possible for certain level position (as I said,
Director or principle Engineer level), but no way a regular Sr. SW will get
that.

70k shares of RSU was possible in summer 2013. It should be for staff
engineers at least. I know a few cases with similar numbers but certainly
all were pretty senior and had several competing offers.
Interesting thing is that all those engineers I know didn't choose to go to
Twitter. :-)
