创业俱乐部都800人了。。。

好久没有更新这个博客了，惭愧 :-(

最近诸事繁忙，做consulting和编程，挺累。但同时，也在培养创业俱乐部。倒是不断的有网友加入的。结果今天偶然一看，wk, 都800人了。这事儿闹的，有些出乎意料了。

不过，想想，现在在美国，风投和各种高大上流行，但哪儿有给我们草根创业提供个交流场所的地方啊？所以，剑知网的这个俱乐部，还是对大伙儿不错的了。

希望这个俱乐部给真正想个人创业的，特别是bootstrap的Chinese entrepreneur们提供一个好的共享信息的地方。

厌倦了朝九晚五的，想自己做自己喜欢的事情并发展成为一份自己的事业的，欢迎来哈，链接如下:

给在美国找工作的同学一个好用的搜索面经的工具

继沉寂一段时间以后，剑知网再次发力，推出了搜索美国面试面经搜索。链接在这里：
http://www.jiansnet.com/about/jobsearch.html

一篇一篇的翻看帖子找面经，太累。还是搜一下方便，省你的时间。可以用来多复习和准备上。

没有搜索的功能，找个东西都费劲；有了这个功能，好比有了clear vision。这就是我自己的感觉，相信与我有相同感觉的同学也有不少吧。

试试看吧，如果好用，记得帮着咱们给多推广一下哈。

先谢谢读这个帖子的各位亲们了。。。

External MergeSort Sample Code

Today I practiced external merge sort just for fun. Here is the java code, for merge-sorting 5 sorted files, each of which contains a list of sorted integers. The input are out0.txt, out1.txt, out2.txt, out3.txt, out4.txt, output is sorted.txt.

import java.io.FileWriter;

import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

public class ExternalMergeSort
{
public static void main(String[] args) throws Exception
{
// initialize n buffers for merge sort
List bufferList = new ArrayList();
for (int i = 0; i < 5; i++)
{
bufferList.add(new MergeSortBuffer("out" + i + ".txt"));
}

// output stream
PrintWriter out = new PrintWriter(new FileWriter("sorted.txt"));

// store merge sort result into output buffer
int[] outputBuf = new int[1000];

// merge until only one mergebuffer left
while (bufferList.size() > 1)
{
int min = -1;
int minPtr = -1;
for (int i = 0; i < bufferList.size(); i++)
{
if (minPtr < 0 || bufferList.get(i).pokeNext() < min)
{
min = bufferList.get(i).pokeNext(); minPtr = i;
}
}

// now we got minPtr buffer, write it out
out.println(bufferList.get(minPtr).getNext());

// remove the maxPtr buffer if it doesn't have elements anymore
if (!bufferList.get(minPtr).hasNext())
{
bufferList.remove(minPtr);
}
}

// output last buffer
MergeSortBuffer buf = bufferList.get(0);
while(buf.hasNext())
{
out.println(buf.getNext());
}

out.close();
}
}

--------------------------------------------------

import java.io.BufferedReader;
import java.io.FileReader;

public class MergeSortBuffer
{
private BufferedReader reader;
private int[] buf = new int[1000];
private int bufSize;
private int start;

public MergeSortBuffer(String fileName) throws Exception
{
reader = new BufferedReader(new FileReader(fileName));
refillBuf();
}

public boolean hasNext() throws Exception
{
return bufSize > 0;
}

public int pokeNext() throws Exception
{
return buf[start];
}

public int getNext() throws Exception
{
int next = buf[start];
start++;
if (start >= bufSize)
{
refillBuf();
}
return next;
}

private void refillBuf() throws Exception
{
int i = -1;
while (true)
{
String line = reader.readLine();
if (line == null || line.equals(""))
{
break;
}
i++; buf[i] = Integer.parseInt(line);
if (i + 1 == buf.length)
{
break;
}
}

start = 0;
bufSize = i + 1;
}

来美国父母老人探亲医疗保险问题

最近根据网上的讨论仔细攒了一篇超强的美国父母探亲保险文章.很多人的父母都有心脏病或者心脏有问题。这种病有时候确实不能耽误。大概的情况就是，即使没有保险也可以去看急诊并且不付或者少付款。 但操作中有些细节的东西， 详情请看USA Visiting Parents Insurance Coverage

FindTheBest.com Alternatives Everyone?

I was searching for comparison engine related topics on the web and came across FindTheBest.com. It is a startup that is trying to do this be-all-end-all type of work, to compare any and all services, products etc.

But, when I visited the site, I have to say, it is not very impressive. The site seems a bit cluttered and search loads slowly, also, the search box slides far to the right hand side. It is a surprise that the search result is powered by Google custom search.

I couldn't believe FindTheBest.com secured a lot of VC funding. A one-man shop like JiansNet.com has good search result, and the best part is that it is not powered by some type of custom search.

The bottom line is that, it is always interesting to see this and other startups popping up from time to time, but only to see that they are still perfecting their technology/websites.

I buy and wear skecher shoes. They are the best, light weight and good quality. Other than Skechers, I also have new balance, Nike etc. But to me, fashion-wise, Skecher shoes are more chic/elegant.http://www.blogger.com/img/blank.gif

Just checked our site, we have some pages that are related to Skechers here:
