An Inside View From a Google Employee

http://blog.outer-court.com/archive/2006-06-15-n22.html

ZorbaTHut says that Google is mostly C++, Java, and Python (or so he’s been told).

“We’ve got extensive automated unit tests, all of which (obviously) must pass.”

Zorba writes that he has only about one meeting per month.

“The company’s structure, at least for engineers, is amazingly flat.”
Zorba says the Google hierarchy is just five levels: Programmer - Tech lead - Manager - 
Department lead - Larry/Sergey/Eric. Google just assumes their workers are competent, 
Zorba adds.

“[M]ost people are Linux-only”

Zorba says that in his opinion, C++ is the best single programming language out 
there. He says however that it also doesn’t protect you from shooting yourself in the foot.

On how Google goes about staffing a Test Engineer position, Zorba replies: “I don’t know 
what other teams are like, but on my team everyone owns their own tests and handles 
their own quality.”

如何寫一份好的師程工簡歷

如何寫一份好的師程工簡歷
1．談到你做過的技術時，應該提到用的程序語言、你的個人貢獻和產品細節。
2．多講事實, 少用形容詞。
3．你獲得的獎、商業的榮譽或表揚、受用戶歡迎的產品和你做過的有難度的業餘項目都該包括在簡歷裡。
4．分清主次，刪掉相比之下不起眼的成績，以免沖淡更加突出的成績。

因為每次yahoo登入都記不住帳號跟密碼, 所以寫了一個簡單的來自動填
順便練習了一下addEventListener的用法,
這樣寫的優點可以等到整各頁面load完之後在開始執行function()的部份.
在這邊有人寫一樣的東西

// @inclue   http://login.yahoo.com/
// ==/UserScript==
window.addEventListener(
         'load', 
         function() { 
                var login = document.getElementsByName('login')[0];
                var passwd = document.getElementsByName('passwd')[0];
                login.value = "username";
                passwd.value = "passwd";
        },
        false
);

Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken
一開始是一個簡單的binary search

1:     public static int binarySearch(int[] a, int key) {
2:         int low = 0;
3:         int high = a.length - 1;
4: 
5:         while (low <= high) {
6:             int mid = (low + high) / 2;
7:             int midVal = a[mid];
8:
9:             if (midVal < key)
10:                 low = mid + 1;
11:             else if (midVal > key)
12:                 high = mid - 1;
13:             else
14:                 return mid; // key found
15:         }
16:         return -(low + 1);  // key not found.
17:     }

如果low+high比int(2^31-1)大的話, 會有bug

作者提供了解決的方法


6:             int mid = low + ((high - low) / 2);

或者

6:             mid = ((unsigned) (low + high)

http://googlesystem.blogspot.com/2006/05/random-files.html
Google indexes not just web pages and documents, but also interesting file types like executables, databases or source code files. To search for a file with a specific extension, you need to use the operator filetype.

1. Find applications.
If you search for [winamp filetype:exe], the first result is a direct link to Winamp 5.08. Searching for [python filetype:msi] brings many direct links to Python 2.4 setup. It's interesting to see that Google actually indexes the files and gets some metadata from them.

2. Find source code.
There's a lot of code available on Google: some on governmental sites, other useful for educational purposes. You can even restrict your search to a certain type of license.

3. Find databases.
You can find CSV files, SQL scripts, DBF files, MDB files.

4. Find feeds.
Get a list of great feeds to import to your favorite feed reader. This way you can search for the feed address of your favorite site, without looking in the source code.

5. Other interesting files.
Registry files, configuration files and, my favorite, Inno Setup scripts.

So the next type you need a file to test an application or to use it as an example, try Google.

Serving JavaScript Fast

He talks about several different approaches, including:

* Monolith - the bigger the chunks the better, less overhead of loading more than one file for each page execution
* Splintered Approach - divide it up into multiple subfiles and only load what you need
* Compression - gzipping up the content to reduce its filesize as sent to the browser
* Caching- sending headers to correctly cache the javascript file(s)
