出，但是想给

Hi everyone,
I am on F1&OPT for the tax year 2010. I received a letter from IRS for my
submitted 8833 (e-filed with taxact):
"Thank you for your recently submitted form 8833......."
"Cut out and return the voucher immediately below if you only have an
inquiry. Do not use if you are making a
payment."
"Cut out and return the voucher at the bottom of this page if you are making
a payment, even if you also have
an inquiry."
I do not understand why I receive this. I have already received the tax
refund in March.
Any suggestion for me?
Thanks.

运动是造成无线通信不稳定的原因
太阳能动力过了傍晚就歇菜
怎么看也不觉得比气球好
感觉就是FB钱多撑着了，对么？

我觉得IRS会再给你退一笔钱，因为我之前遇到过一样的情况。你是Non Resident吧，
你的退税是寄
到Texas的是么？

Are you serious?
What back haul link is it using? What is the point of using laserU/L, not
even mentioning its technical difficulty to get good LOS channel.
Given its size, its solar probably can do 5kw using the best solar cells. I
guess that would be hard to sustain 24 hours flying. But I do not know
typical requirements here.

are u too stupid to read through internet?
You want to do your own "science equations" to prove your preciseness.
But your thoughts is based your own imagination . There is nothing
impossible. Your school skill is stupid and lame.

I am not as stupid as jerks like you who believe in ambitious Internet press
without own technical justification.
I am not talking about anything technical impossible, I am talking about lab
results vs real deployment.
Going up high at 60000-90000ft, maybe you can educate us the typical
pathloss and channel model for the that spectrum band?
So if you are half as smart as you think of yourself, better show some
technical knowledge instead of just dog barking.
Of course if you are in the FB team, you have all rights to keep whatever
confidential. No one forces you to answer anything. I am just asking a
question anyway.

我觉得后面有军方的影子.
1)能够在一个地方连续飞行30多天的无人自动飞机,就是一个最好的侦查平台.
2)使用地面激光连续照射一个空中物体;一个空中物体使用激光连续照射地面目标.这不
就是军队最常做的"射击"训练吗?或者说, 不是激光的话,可能就是一个大分辨率相机,
24x7的瞄准一个地面目标拍照或录像或实时转播,这是干什么?
很可能这就是一个军方项目的基础研究,只是为了保密,编造一个可笑的民用理由.这个"
supply internet to rural area"的理由太可笑了.连网都不能上的地方,能不能有电还
是个问题.现在有电话就能上网,不能上网的地方的人就是不需要用电话,难道他们会为
了上facebook网站专门买个手机??
想来想去,最可能的用途就是军队出去打仗的时候,到了哪里就发个飞机提供局域网络,
供大兵使用.比如说美军打到伊拉克去,显然不能让大兵去当地isp买无线上网sim,军队
又总是呆在荒无人烟的地方.说到底还是军方项目.
