考虑到很多人可能今天第一次使用Opera（自从Opera免费以来），所以我想让你在需要的时候可以知道如何获取帮助。你可能倾向于忽略帮助菜单，但是最好不要！那里还是有很多好东西的。

今天的主题是解剖学-但是Opera的解剖学不同于人类解剖学，因为膝盖骨不是必须和大腿骨连接的-需要的话，你可以把它连到颈骨上。但是我们还是有一些原则要遵循的，下面的内容就是帮你了解一些基本的名词。

Solidot - 希捷的750G硬盘:

希捷网站的一个PDF文件泄露了即将推出的750G梭鱼7200.10 硬盘的情况。这种硬盘第一次在桌面电脑上使用垂直记录，带有16M缓存，7200RPM 。拥有ST3750640A (PATA) 和ST3750640SA (SATA) 两种模式。图片展示了该系列的不同型号。

折腾了半天，终于成功地把Opera里面的数千封email成功地导入了Seamonkey。办法如下：

1. 下载MBS2MBX。如果是Opera 7的话，下载V1.2就可以了；7.5以上的可以下载1.6版本；
2. 解压，因为是Python程序，需要安装Phython2.3以上运行；
3. 运行后界面如下，选择你的Opera Email的文件夹，然后选择导出的文件夹，如果多账号且需要分开的话选择account.ini文件，然后运行”Start Mbox-conversion”，会有进度显示到完成；
4. 完成转换后，启动Seamonkey/Email，工具-〉导入-〉选择Eudora，然后选择保存的文件夹位置，就可以转换了。一切顺利的话，你的Opera中的邮件就可以成功地导入Seamonkey了。我操作的大概是4000封左右的邮件，一切OK；
5. 当然了，为了安全起见，请做好相应的备份工作。

All my years in studying Urban Planning helped me grow a greater appreciation for the dense downtown skyline of the big city. The downtown core of big cities across the Americas, Europe and Asia are the cultural pulse and economic engines of urban regions where millions of people live. All urban “life” begins and ends, each day and night under the watch of the city’s tallest skyscrapers and most grand architectural structures. So kick back and appreciate the view that they have to offer…

1. Hong Kong, China
Hong Kong is number one on my list for many reasons: Hong Kong has a whopping 43 buildings over 200 metres tall, 30 of which were built in the year 2000 or later!!! It also boasts four of the 15 tallest buildings in the world… that’s all in one city! Hong Kong’s skyline shows a large selection of distinct sky-reaching towers, with beautiful night lighting and reflection. This city exemplifies the post-modern skyscraper and skyline. Finally, the mountain backdrop makes this skyline (as you can clearly see) the greatest on the planet!
Metro/Urban Population: 6.9 million

2. Chicago, USA
Chicago is the birthplace of the modern skyscraper. When Chicago built its first steel high-rise in 1885, it was not the tallest structure in the world but the first example of a new form of engineering that would change nearly every city on earth. Chicago has 19 buildings over 200 metres tall (three of which are among the top 20 tallest buildings in the world, including the tallest in North America). Chicago has some of the finest mid-century architecture and examples of modern skyscrapers.
Metro/Urban Population: 9.5 million

3. Shanghai, China
Not to be mistaken for a space station, Shanghai is a real city! China’s biggest and most advanced city, Shanghai was said to be the most cosmopolitan city in the beginning of the 20th century, but lost its glory during the “Mao era”. It is now quickly regaining its position as one of the biggest economic powerhouses in the world as well as a showcase of modern architecture. In Shanghai you’ll find 25 structures that are over 200 metres tall, one of which is the insanely tall, the 468m downtown Oriental Pearl TV Tower.
Metro/Urban Population: 13.1 million

4. New York City, USA
New York City has one of the densest and most diverse skylines, with a huge collection of buildings and building styles. Thanks to Hollywood’s obsession with the city, it is also the most easily recognizable skyline in the world. New York City has an amazing 47 buildings over 200 metres - the most in the world! The four tallest buildings in NYC were all built in the early 1930s! Home of the famous, (now tragically destroyed) World Trade Center Towers, the Empire State building, the Statue of Liberty and the United Nations, New York City is the financial capital of the western world! Upon the completion of the new “Freedom Tower” (built on the old site of the World Trade Centers), it may rank higher in this list.
Metro/Urban Population: 21.0 million

5. Tokyo, Japan
Tokyo is the world’s most populated city. Its skyline has a number of unique characteristics that set it apart from other big city skylines, among them 15 structures at over 200 metres tall (including the Tokyo Tower which changes colors every night). But because of the density and vast size of the city, every corner appears to have its own skyline. With the height restrictions and the required red lights that flash atop all mid to tall-sized buildings make the city look spectacular at night. Tokyo is filled with neon lighting and unique, contemporary architecture, and like New York City is also often portrayed in movies for its aesthetic and eye-catching cityscapes. Interesting fact: Tokyo houses the world’s largest fleet of helicopters to get around town if traffic gets too crazy.
Metro/Urban Population: 32.0 million

6. Singapore
One of the best (urban) planned and cleanliest metropolitan cities in the world, Singapore looks like an architectural model city come to life. The buildings cannot be higher than 280 metres due to air traffic control restrictions, but that has added a tall (but not too tall) and consistent building height and space pattern that makes this skyline unique: Three buildings are exactly 280 metres tall and 5 others (8 total) stand at just over 200 metres. The buildings are mostly light-coloured and there is a large expanse of greenery dotted around the city core. This South-Eastern city is definitely in a league of its own.
Metro/Urban Population: 3.8 million

7. Toronto, Canada
Toronto is a meeting place, a crossroads of many cultures and ethnicities. Toronto is downtown Canada, the biggest city in the country with a skyline to match. Toronto has 7 structures in its skyline that stand at over 200 metres, including the astonishingly tall 553 metre, CN Tower, which is often referred to as the tallest free-standing structure in the world. While mostly untrue (because there are taller TV masts in the world), the CN Tower possess the world’s highest observation deck, making this city’s skyline one of the most immediately identifiable.
Metro/Urban Population: 5.1 million

8. Kuala Lumpur, Malaysia
This is probably the most impressive city worldwide that has less than 2 million residents. Marvelous modern buildings reach the sky here, and while the skyline is not too dense, it does allow buildings to soar and stand out. Kuala Lumpar has three of the 25 tallest buildings worldwide, including the tallest twin buildings, the Petronas Towers (which are arguably the second and third tallest overall in the world) as well as the 420 metre Menara Kuala Lumpur Tower.
Metro/Urban Population: 1.5 million

9. Shenzhen, China
What was a tiny fishing village on the border of Hong Kong in 1970 is now a buzzing metropolis of over four million people. With 13 buildings at over 200 meters tall, including the Shun Hing Square (the 8th tallest building in the world), Shenzen is a marvel of lights after sunset. You can’t help but ask yourself if you are in a video game or in a real city.
Metro/Urban Population: 4.2 million

10. Seoul, South Korea
This city’s skyscrapers are divided into many clusters, spread amongst the main businesses and residential districts. Most of the recent growth in Seoul’s skyline, however, has been of residential towers over 60 storeys high that are shooting up like blades of grass! There are 10 buildings in Seoul over 200 meters tall and much of the mid-rise to high-rise structures are lined up in a linear fashion, creating a “wall” of buildings like no other. Seoul is where the ancient Eastern world meets the modern West.
Metro/Urban Population: 20.8 million

11. Sao Paolo, Brazil
“What building did you say they lived in?” Finding it in the largest mass of condensed apartment buildings anywhere would be like finding a needle in a haystack. Sao Paolo has a population of over 18 million people! While the buildings are not super tall (with only a single structure at over 200 meters tall) this skyline is nevertheless stacked. Sao Paolo has a fleet of over 500 helicopters, the second largest helicopter fleet in the world.
Metro/Urban Population: 18.3 million

12. Sydney, Australia
Australia’s showcase city, Sydney has one of the most recognizable skylines due to its world-famous harbour, often referred to as the most beautiful natural harbour in the world. The Sydney Harbour has many bays, inlets and secondary harbours. It is spanned by the monumental Harbour Bridge, and the Opera House decorates the shoreline like a white flower. The Sydney skyline is world-class with hundreds of skyscrapers in the central business district and many more high-rise buildings in the outlying neighbourhoods. Sydney has 8 buildings over 200 metres tall.
Metro/Urban Population: 4.2 million

13. Frankfurt, Germany
Certainly one of Europe’s most interesting cities in terms of skylines, Frankfurt is home to five structures that are over 200 metres tall. These modern skyscrapers are marvels compared to those other, mostly non-existent ones scattered across European cities. The contrast here is interesting: The city combines low-rise, high-density traditional European architecture (some of which is over 1,000 years old), with modern towers that stick out like sore thumbs, but are impressive nonetheless.
Metro/Urban Population: 4.1 million

14. Dubai, United Arab Emirates
Is this a mirage in the Middle East? Seemingly out of nowhere emerges a city in the middle of a desert. This is Dubai, a city that produces only the best modern architecture in the world. Already home of the world’s tallest all-hotel building and the tallest all-residential building in the world, AND currently proposed to build the world’s tallest building, this skyline might just leap to the number 1 spot in the near future. While the skyline is not so dense, each building is a marvel all on its own. As a skyline it probably can’t compete with the larger cities, however the individual buildings in this city are by far the greatest examples of modern architectural accomplishments. All seven structures in this city at over 200 metres tall were built in 1999 or later - that’s how new this city is.
Metro/Urban Population: 1.6 million

15. Seattle, USA
Seattle is the commercial, cultural and advanced technology hub of the Northwest USA and a major port city for Pacific and European trade. Home 4 buildings over 200m and the famous 184m Space Needle observation tower, Seattle is surrounded by mountains and water and offers some picture-perfect views. Seattle is commonly referred to as the Emerald City and renowned as a great social and corporate city with great planning.
Metro/Urban Population: 3.6 million

Honorable Mentions

16. Pittsburgh, USA
Although Pittsburgh only has two buildings over 200m tall, its skyline is very impressive nonetheless. Pittsburgh has nicknames like the “city of bridges”, “the Burgh” or the “golden triangle” which outlines its true characteristics. It is surround by three rivers and the CBD is shaped in a triangle and surrounded by golden color bridges. The city is also surrounded by hills and valley’s giving access to great views of the city. The city has not had a major skyscraper raised since 1988, but good planning and a scenic surrounding region still makes it a great skyline.
Metro/Urban Population: 2.4 million

17. Guangzhou, China
Guangzhou is a very modern city, yet it is called “the City of Flowers,” as each of its spectacular skyscrapers is surrounded by grand green spaces and flower beds. Although it only has six structures at over 200 metres tall, there are plenty of other high-rises, each displaying a design that stands out in its own respect. This includes the 391 metre, 80-floor, CITIC Plaza which appears transparent against the (usually) clear blue sky!
Metro/Urban Population: 4.1 million

18. Dallas, USA
The “Big D”, is a major inland American city. The city and metropolitan area lies amidst vast, high, and varying rolling prairies - with hundreds of large & small lakes, rivers, creeks, waterways and meanders. But Dallas; downtown is the center of the Forth-Worth-Dallas Metro Region which is home to 5.9 million people. Dallas’ skyline is home to 7 buildings over 200 meters and the 187m Reunion Tower which looks like huge sphere of light! The skyline is very distinctive at night as it building lighting is very colorful, particularly with lots of green.
Metro/Urban Population: 5.2 million

总是在不停的自我贬抑和自我改进中存活，然而效果并不明显，因为未尝觉自己的进步。想如果某一天，我失去了自省奋进的动力，却活在贬抑中，岂不是莫大的痛苦，虽不觉得现在是快乐。还是那句话，人，还是要有理想的；当你理想渐渐幻灭的时候，才是真实的人生。

Just a testing from outside.
