1. www.Jobguideweb.com
, 此网站将Indeed和Simplyhired上的信息综合在一起，可以叫做advanced
aggregator, 用户可以在首页直接点击感兴趣的职位，尤其适合IT, engineering, web
,
finance等行业。
3. Indeed.com, simplyhired.com
这两个网站都是Job Search Aggregator, 将来自众多企业网站和招聘网站的信息综合
在一
起，信息比较全面。但也不是万全的，有的小公司或者小网站上的信息就不能被这两家
搜到。
3. Monster, careerbuilder, hotjobs
这就是传统的三大网站，不过已经是日趋衰落了，recruiting agency发布的信息的比
例越来
越高，这些机会大多是Contract. 但是这三个网站投递简历还是比较方便，在上面发布
简历也有
机会被Recruiter找到，但要经常update。
4. Linkedin
这个网站的求职功能日益增强，但是职位要求相对比较高。

发帖数: 55 | 3 I'm running some test based on 802.11n using iperf.
iperf allows me to specify the size of a data packet. However, 802.11n
introduces packet aggregation mechanisms (i.e., A-MSDU and A-MPDU). As a
result, the packet size on the MAC or PHY layer may not be equal to the
packet size specified in iperf.
Is there a way to know the length of the data packet on the MAC layer and
PHY layer before a transmission?
I tried wireshark, but it only analyzes the packet structure above the MAC

发帖数: 29 | 6 I think the way polymer dispersing in water is very different
from the way water dispersing in polymer, e.g., water aggregates
then coalesces, which forms very good spherical structure. However,
Non-water soluble polymer in water tends to aggregates, but is hard to
coalesce, which forms a fractal structure.
This is only my GUESS.

发帖数: 190 | 7 3mg/ml concentration is high enough...one possibility is that your polymer or
copolymer is a highly aggregated polymer, which means there is no indivadual
marcomolecules in the polymer solution, just big particles. If the
particles are big enough, say >0.45micron, after filtering, no polymers will
be left in the solution, or cut off by guard columns. If so, no signal can
be detected in main columns. The viscosity measurement will tell you how
serious your polymer aggregation is.
