我的J1今年6月到期,今天收到院里小米发的邮件提醒该去renew我的J1身份了。于是问
老板,老板说,新的funding还没拿到,现在无法跟我续签合同。问小米,小米说,也
不知道renew J1 visa status需要多久。
想请问一下:
1. 所谓的J1 visa的renew是不是就是重新签个DS2019?需要去大使馆把护照重新renew
吗?我的护照上visa状态也是6月到期的。
2. 如果不换地方,renew一下J1 status 需要多久?
3. 如果换地方,像我6月到期,最迟什么时间要得到新老板的offer并renew我的J1呢?

你在这里的合法居留的文件是ds2019和i94,visa只是你进入美国的时候才有用。
你的visa 6月到期的意思是在6月之前你可以多次往返中美。

楼上抱怨IDE的那位明显是没有用python做过科学计算的。
IPython(以及IPython Notebook)是最好的做交互式的数据分析的平台。

Short answer: impossible! They are for different purposes.
Long answer:
If you ONLY use the plotting mechanism. Of course, there are tons of
alternatives to MATLAB. In some aspect, using MATLAB only for plotting is
purely extravagant.
MATLAB thrives on its toolboxes. It hires lots of big sharks in all fields
to work for its libs. Python NEVER has any chance or intention to compete
because it is free and aim to provide a "real generic" programming language
to ease daily life ...
From time to time, there will be some good libs in python/C/C++ in emerging
fields. But MATLAB will always catch up very soon and hire those top
scientists.

:-),我确实没用过matlab做出产品级别的东西,我在工业界也没应用过matlab。
我以前用matlab做统计和machine learning,后来用open source的R和python完全取代
,而且还做的更好。
matlab很强的image processing,近年来也有被python抢饭碗的趋势。
可能你比较有工业界matlab的应用经验,能不能给大家介绍介绍工业界的具体应用好吗
?能否进一步介绍介绍,具体是哪些领域,以及,为什么matlab在这些领域的应用是很
难被开源的软件所取代的呢。
先谢谢了。

You must confuse me with other ID. I never 大骂python.
In our projects we use python intensively. I also answered several python
questions on this forum.
No popular language is 坑, you just need to use it for correct things.
In my team, we use MATLAB for system analysis, math/scientific model
verification; Labview for hardware prototyping; use python for daily
scripting, prototyping and non-performance-critical components; use C/C++
for performance-critical components; java for web backend ...
Someone said MATLAB also have OOP and GUI. But to me, MATLAB's OOP and GUI
are really crappy, one should avoid them. Even they start to adding much
more features since 2010, it is still crappy and buggy.

Productive image processing is never been strong in MATLAB ... But I think
it is still popular for computing vision prototyping in research groups.
Though I am using python for CV prototyping but from time to time I still
need to compare the result to MATLAB. For pure image processing, I do not
have enough experience to discuss.
Statistics toolbox is about précising implementation. For publication, the
most important thing is novelty thus R is far more popular in journals. But
finance companies need speed and completeness, thus MATLAB is dominating in
industry. My friends from banks told me that it is common that companies
hire scientists to translate some novel method from R to MATLAB toolkit. But
Revolution R is changing the situation, now R is also used in companies
like google, facebook for machine learning. However, the license is not
cheap either.
Statistics is ONLY one of the important fields in MATLAB. I think MATLAB is
more for physical sciences. Its symbolic math is also primitive, I guess
mathematicians may dislike MATLAB.
