发帖数: 6519 | 1 I am trying to write a user-level thread library in C. My strategy is to use
ucontext_t, signal, sigaction to support thread creation, initiation, join,
mutex, yield, cancel, and exit.
Without pre-emption, my code currently works with all the methods. But when
I try to add pre-emption support, the program seems running funny and
confusing. So I need to see some examples, better implemented in C.
I am new to C, and have only started C program from 20 days ago. I am
comfortable with using struct, ... 阅读全帖 |

On April 25, 2012, the U.S. Supreme Court heard oral argument in Arizona v.
United States, involving the constitutionality of the State's effort to
combat illegal immigration. In one sense, it was a rematch between former
Solicitor General Paul Clement, arguing for Arizona, and the current
Solicitor General, Donald Verrilli, contending for the United States. The
two had squared off just a month before in United States v. Florida, the
battle royale over ... 阅读全帖 |

发帖数: 7349 | 3 What to do? Diplomacy now has even less to offer. Any appeals the North may
make to America for the normalisation of ties have only one aim: the
withdrawal of America’s 28,000 troops from South Korea.
And so pre-emptive strikes against North Korea are being talked about. South
Korea recently said it would hit first if it believed the North was about
to throw a punch. In Washington, some think-tankers now discuss, with
surprising acceptance, the merits of attacking North Korean nuclear
facilities... 阅读全帖 |

发帖数: 1 | 4 "我印象中，依法支出 5% 就达标了。"
我不知道 IRS 怎么界定，但他们会严格审查你的支出是否符合你的目的？如果不符合
，他们会取消你的免税优惠。Nonprofit tax emption status 是随时可以取消的，所
以 np 财务上不敢乱搞的！
“如果八肥捐款一亿元，可以抵税5千万，因此国家税收就少了5千万”
诶，同学，税不是这么抵的，好不好？Tax deduction 跟 tax credit 是两回事。捐款
可以当作 Tax deduction 但不是直接当作 tax credit.
“捐出的一亿元仍然在6八肥控制的实体下，只需要花费5%，剩下资金，随便怎么用。”
撇开 5% 这数字的正确性先不说，我上面讲了半天的意思就是：很多人在监督 np，包
括 IRS，所以他们的钱不能随便乱花的。严重时会被取消免税优惠的！
可有看得出来你对 Np 与 buffet 这种人很愤怒，但有些事情/常识，最好先搞清楚再
愤怒。

你说得是这个吗
in most cases, you also will not need to report the income on your Form 1040

W2，只不过是box1是0，
我仔细看了一下pub519，觉得因该如此填写
1）line7写入0，line21写入-1042s，同时注明xempt income,” the

发帖数: 77 | 7 我2013年9月H1B来美做非赢利性研究，根据中美tax treaty Article 19，前三年免税
，现在的问题是2016年1月获得绿卡，还能不能继续享用免税到2016年9月。
前三年报税的时候，记得在版上查到过非常确定的说法：变成绿卡后，如果继续从事非
赢利性科研工作，依然可以享受免税到三年期满。现在找不到那些帖子了。
按照如下Publication 519中的说明，中美的tax treaty适用于绿卡， 其他国家的
