RIO DE JANEIRO, Brazil—In her first televised speech since wining the presidential election, Dilma Rousseff, the next head of state of Brazil, praised current President Luiz Inácio Lula da Silva and emphasized women's rights. She also promised to respect freedom of religion, freedom of the press, and human rights, but above all, she will work to eradicate poverty, reported O Globo.

“We cannot rest while there are hungry Brazilians and while poor children are abandoned to their own luck,” said Rousseff. “It is about an abyss in a developing Brazil.”

Indonesia’s Mount Merapi erupted again Monday, spitting smoke, ash and hot gasses, AP reported. So far no injuries have been reported.

Merapi, the most active of Indonesia’s volcanoes, has erupted several times since Tuesday Oct. 26, killing 38 and forcing the evacuation of 40,000 residents to temporary shelters.

“There are more and more refugees coming down the mountain,” Rukman, the head of disaster response for the Indonesian Red Cross (PMI), told the Christian Science Monitor. “We need water and better sanitation; that is the big problem.”

Chinese Public Warned to Expect Further Inflation

2010-10-31T13:34:00.001-07:00

T
hough inflation exists in China, rarely will an official warn the public to expect it to continue.

A member of the Chinese National Development and Reform Commission recently spoke anonymously to domestic media, saying that further interest rate increases will not control inflation so the public must simply be resigned to it, according to Deutsche Welle.

Subsequently, many media outlets, including China's state-run Xinhua News Agency, reported numerous responses from Internet users. The public decried the NDRC’s warning as illogical.

US Govt. Investigating China Trade

2010-10-31T13:33:00.000-07:00

WASHINGTON—The United Steelworkers union (USW) opposed China’s entrance into the WTO ten years ago, fearing the loss of American manufacturing jobs. Today, the steelworkers are still fighting, saying that by not adhering to WTO rules, China gets an unfair advantage over the United States.

“We fought China’s accession to the WTO because we know that they cheat and they lie and they say we want to be players and play by the rules, and they don’t,” says Gary Hubbard, a spokesperson for United Steelworkers.

In September the U.S. Trade Representative accepted a 5,800-page petition from the USW accusing China's clean energy sector of wide-spread violations of WTO rules.

China’s ‘Map World’ Without Google

2010-10-29T12:52:00.000-07:00

hina’s State Bureau of Surveying and Mapping (SBSM) announced that it will redistribute the market of Internet maps at the end of this year or early next year. Noticeably, Google Maps is not included.

On Oct. 21, China’s Map World, a national, public Internet service of geographic information, was officially up and running. The new Map World has almost the same functions as Google Maps. Information includes roads, water systems, administrative districts, residential areas, and geographic names. It has real-image mode and three-dimensional mode. It also provides information on business locations, such as shops and restaurants. According to the SBSM, Map World will be updated every six months. So far, this website cannot provide high-resolution images of areas outside China.

In March, Google withdrew its Internet search service from China and moved its servers to Hong Kong to avoid Chinese regime censorship. Since then Google’s Internet service market share has been dropping in China. However, mainland Internet users can still access Google, including its map service, through the Hong Kong server.
Chinese Business License

In the past, map information in China has been classified as military secret. And survey and mapping services are still restricted in China. A company must obtain a license before it can provide these services. To apply for the license, the company server that keeps the mapping information must be located inside China, and the company must provide the server’s public IP.

In May, China issued a new regulation called and said all companies who provide Internet geographic information must apply for business permits.

The that were announced in 2007, stipulate that foreign businesses involved in mapping in China, must have joint venture and cooperation with a Chinese business. Also, the Chinese company must be the holding company.

As of the end of September, authorities have issued business permits to 31 companies, including Tencent, Baidu, Sina, and Nokia. Google is not among them.

Since Google Maps did not get a license to operate in China, it has no chance of entering the map service market in China, unless Google moves its servers back to China and agrees to let a Chinese company hold the majority of its stock.

Same Satellite Images

After China set up Map World, Chinese media said that the software is the intellectual property of the Chinese government. However, a Chinese Internet user found out that the satellite images on Map World and Google Maps are exactly the same in many instances, including the number of cars on highways, the cars’ shapes, positions, and colors. The Internet user surmised that the two satellite maps have to come from the same source.

Jiang Jie, Chief of the Bureau’s Center of National Basic Geological Information, admitted, “the satellite images are purchased from overseas.”

So far Google has not commented.

Resolve around File Descriptor limited on Reactor Select (selector)

2010-03-23T16:43:00.000-07:00

I've been running into problem file descriptor run out using the default reactor. By default, twisted got hardcode the file descriptor to be 1024 (MAX). If you want to change the default MAX need to modify code and recompile. Or we can use the pollreactor to increase several thousand more.
>>
from twisted.internet import pollreactor
pollreactor.install()
<<
usage as normal:
from twisted.internet import reactor

Even if you change the ulimit on filesystem, it doesn't change with the library. This is something hardcode inside twisted lib.

Creating a self-signed cert with one command

The following command will generate a new key and create a certificate all in one line suitable for use by Apache or any other SSL tool.

openssl req -new -newkey rsa:1024 -days 365 -nodes -x509 -keyout www.example.com.pem -out www.example.com.pem

You can then use the file above in apache with the following two lines

If webalizer is not found, you have to add sources in /etc/apt/sources.list: can comment the universe sources.

Enable the apache2 hostname resolution: go into /etc/apache2/apache2.conf: Change
```
HostnameLookups Off
```
into
```
HostnameLookups On

By default webalizer is not well configured: it does not check in the good log. In /etc/webalizer.conf: Change
```
LogFile         /var/log/apache2/access.log.1
```
to
```
LogFile         /var/log/apache2/access.log
```

Test webalizer:
```
sudo webalizer
```
If you get a warning like warning: Truncating ...
It is because you did not put the hostnameLookup. If afterward, you get this message, it can be because you are attacked by a virus...

Run webalizer as a cronjob. This has to be run as root: Edit the root cronjobs by running the command:
```
sudo crontab -e
```
and add the line:
```
0 * * * * webalizer
```
With that line, every hour webalizer is run

Gương người xưa: Thực hành nhân đức và để lại tiếng thơm

2010-02-24T09:39:00.000-08:00

Trương Phương Bình, sống ở Nam Kinh dưới thời Bắc Tống, là người khoan dung nhân hậu và trọng lễ nghĩa. Ông luôn giữ vững tiết tháo cao thượng và rất tin tưởng vào Thần Phật. Là người có phong cách cao nhã và độ lượng, ông luôn được nhiều người kính trọng.

Vào mùa thu năm 1054 sau Công nguyên, tức năm Chí Hòa thứ nhất đời vua Tống Nhân Tông, có một tin đồn ở vùng Tứ Xuyên truyền đến rằng quân địch đang sắp sửa xâm phạm biên giới. Quân sĩ đóng nơi biên cương tỉnh Tứ Xuyên nửa đêm được tin vô cùng kinh hãi, trăm họ đều tháo chạy, đạo tặc nổi lên khắp nơi, trật tự xã hội trở nên đại loạn.

Khi tin tức truyền đến kinh thành ở Khai Phong, cả triều đình từ trên xuống dưới đều chấn động kinh hãi. Tống Nhân Tông phải tìm người chủ soái để phái đi dẹp loạn, bèn nói với triều thần: “Đừng gây nên họa loạn, cũng đừng khiến nó trở thành sự biến. Dẫu rằng tin đồn trong dân chúng có tới tấp đi nữa, nhưng chủ ý của Trẫm đã định, họa xâm lăng chưa chắc là sẽ đến, chỉ sợ sự biến nổi lên từ nội bộ mà thôi. Sự việc này cần giải quyết theo cả hai cách là ‘nhu văn’ và ‘võ công’. Trẫm cần một hoặc hai vị đại thần đi xử lý chuyện này một cách khéo léo. Ai có khả năng làm nổi sự việc này, Trẫm sẽ phái người đó đi chiêu an quân dân của Trẫm”. Mọi người trong triều đều tiến cử Trương Phương Bình. Tống Nhân Tông đồng ý và phái Trương Công đi. More

Petitioners Beware: Detainment, Detainment, Then ‘Reeducation Through Labor’

2010-02-24T09:36:00.000-08:00

This billboard reads 'Persistent and Noisy Petitioners: First time—detention, second time—detention, third time—Reeducation Through Labor,' set up by 'The Chinese Communist Party Tianxin Township Committee, Tianxin Township People's Government.' (Photo by anonymous citizen)

A billboard with a foreboding message erected beside a road in Jiahe County, China’s Hunan Province, is indicative of the ruling regime’s tighter control of dissent, according to commentators: “To All Persistent and Noisy Petitioners: First time—Detention; Second time—Detention; Third time—Reeducation Through Labor.”

According to an eyewitness, this sign is located in Tianxin Township in Jiahe County to the right of a highway. Standing in a fork in the road, the sign stood at 7-8 square meters and was inscribed with “The Chinese Communist Party (CCP) Tianxin Township Committee, Tianxin Township People's Government.” Photos of forced labor detainees, large handcuffs, and policemen with austere expressions made it a startling sight, according to an observer.
