我家人因为雾霾肺都不好了，估计已经到了快肺气肿的地步。一般国内怎样才能防PM2.
5啊？家里是不是要买个空气净化器啊？哪个牌子的靠谱呢？谢谢

在美国LA,
如果补办会象护照一样要很长时间吗?
如果重新申请2年的,会从现在的时间算起吗?不会只给剩下的一年吧?
谁有经验啊?谢谢...

我的H1-B 今年十月份就满3年了,最近需要让公司的律师帮我办H1-B的延期。想请问一
下，如果从现在到10月份这期间，我换了新的工作，原雇主帮我做延期这件事会对更换
H1-B的sponsership有什么影响么？
个人感觉，H1-B的延期和sponsership是没有冲突关系的。。。但是还是想听听有经验
的人的意见。
非常感谢！

recently ran into some questions regarding what java is doing when its
starting virtual space is 2G, while running a no-op program.
then I dug into what happens when malloc() is called.
it looks malloc() has 2 mem management methods: it has its own cache of
memory blocks, using "buddy" algorithm, then for larger block requests, it
just mmaps() an anonymous block , **** essentially delegating the task to
kernel mem management *****
then my question is , what happens to kernel when it tries to allocate a
block? it seems that it is never a problem when you request large blocks
that are bigger than several pages, right? ---- you don't have a problem
with finding continuous memory blocks, since all the pages are mapped by
page tables. kernel mem management is only concerned with managing requests
for small blocks (smaller than 1 page ) ???
thanks lot

有经验，虽然年头不是很长
面试了几家，有的都给background check了，就是没有offer
真不知道问题出在哪里了，好灰心
我知道现在经济不好，一个职位很多人申请，没有办法，竞争力不行吧
不知道拿到cpa license能有多大帮助，我现在在准备考试阶段

空气净化器也许有点帮助，但你不可能不出门吧，最好还是搬到空气质量好点的城市。
我最近去福州，感觉那里的空气质量很不错，基本上每天都是良好。

I am trying to answer your questions. However, it is involved in some
complicated mechanism which I can't explain easily.
what happens to kernel when it tries to allocate a
block?
--If you are asking for a block of physical memory, then kernel will
allocate it from its buddy manager.
it seems that it is never a problem when you request large blocks
that are bigger than several pages, right?
---Sure, kernel can allocate a large block, but maybe less than 1024 pages.
This mechanism may change with different kernel version.
you don't have a problem with finding continuous memory blocks, since all
the pages are mapped by page tables.
---yes, Normally user space program won't need continuous physical memory at
all. Only those related to hardware will need it.
kernel mem management is only concerned with managing requests
for small blocks (smaller than 1 page ) ???
---It depends. Those small blocks are managed by slab allocator. Kernel
surely need to manage those requests larger than 1 page.
