Systems Thoughts

Days ago I found the “previous entries” link on my index page didn’t work, the link connected correctly to “page/X/” but no pages were shown. Since I just upgraded my wordpress to 2.3.3 it is unclear whether the problem is caused by the bug of wordpress or not.

Search results helped nothing with this issue, changed the template back to default showed the same error pages. But suddenly I recalled that maybe it has something to do with those permentant link migration plugins. So I turned off all those plugins I kept from 2.3.

Now problems had been solved and finally I can read my old articles agian….

BTW: Two plugins caused this problem: Permalink Redirect, Dean’s Permalinks Migration. Or I should not use them in the same time?

最讨厌的就是旅行回来发图片，碰上我这个完美主义者每个照片都要花费大量时间。这个帖子在wp里存了好久了，怕长虫就发了吧。其他照片估计遥遥无期了。

去柏林大家最熟的,长途汽车总站,Zoologistgaten(济南长途车站离动物园也蛮近,难道也是当初德国人规划的?

This is a log for my thesis study on Stochastic Pi-Calculus Machine (SPiM).

Here is a sample code for implementing hill-type equation in SPiM:

directive sample 10.0 1000
directive plot sender();receiver()
directive graph
new comm@1.0:chan(float)
let sender(n:float) = (
!comm(n);
sender(n/2.0)
)
and receiver() = (
do delay@1.0; receiver()
or ?comm(n); delay@n
)
run (sender(1.0)|500 of receiver())

You will get a curve looks like this:

The receiver()’s degrade time is controlled by n which becomes half fold every stochastic time period. For more complex equations I think you can modify sender() and pass your private channel for communication though the parameters. Then the result will not be seen by any other processes, hopefully:). But I haven’t test it yet.

便宜没好货，果然是真理。前一阵空间到期想找个便宜的空间移了算了，后来发现了Startlogic只要3.99$/月，马上就交了订金。结果麻烦连连，就只是换DNS就换了两天。PHP怎么也运行不了，Panel难使，技术咨询基本等于没有。用了不到一个星期就恶心的我不想用了，脑子里全是dreamhost的好…

现在重新换回dreamhost了，不过是月付，$11.99 一个月。但是我还在寻找更好的hosting，更好，更强大~
