full_context: Document 1: Ultima Tower: The Ultima Tower is a hypothetical supertall skyscraper, designed by American architect Eugene Tsui in 1991. It has been envisioned to be built in San Francisco, California and could accommodate up to 1 million people. With a total height of , the tower would be 2 miles tall, and comprise 500 stories if built. It is one of the tallest buildings/man-made structures ever conceived.
Document 2: Transamerica Pyramid: The Transamerica Pyramid at 600 Montgomery Street between Clay and Washington Streets in the Financial District of San Francisco, California, United States, is a 48 - story postmodern building and the second - tallest skyscraper in the San Francisco skyline. Its height will be surpassed by Salesforce Tower, currently under construction. The building no longer houses the headquarters of the Transamerica Corporation, which moved its U.S. headquarters to Baltimore, Maryland, but it is still associated with the company and is depicted in the company's logo. Designed by architect William Pereira and built by Hathaway Dinwiddie Construction Company, at 853 feet (260 m), on completion in 1972 it was the eighth - tallest building in the world.
Document 3: Houston: Centered on Post Oak Boulevard and Westheimer Road, the Uptown District boomed during the 1970s and early 1980s when a collection of mid-rise office buildings, hotels, and retail developments appeared along Interstate 610 west. Uptown became one of the most prominent instances of an edge city. The tallest building in Uptown is the 64-floor, 901-foot (275 m)-tall, Philip Johnson and John Burgee designed landmark Williams Tower (known as the Transco Tower until 1999). At the time of construction, it was believed to be the world's tallest skyscraper outside of a central business district. The new 20-story Skanska building and BBVA Compass Plaza are the newest office buildings built in Uptown after 30 years. The Uptown District is also home to buildings designed by noted architects I. M. Pei, César Pelli, and Philip Johnson. In the late 1990s and early 2000s decade, there was a mini-boom of mid-rise and high-rise residential tower construction, with several over 30 stories tall. Since 2000 more than 30 high-rise buildings have gone up in Houston; all told, 72 high-rises tower over the city, which adds up to about 8,300 units. In 2002, Uptown had more than 23 million square feet (2,100,000 m²) of office space with 16 million square feet (1,500,000 m²) of Class A office space.
Document 4: Sociology of the Internet: Governments are also getting online. Some countries, such as those of Cuba, Iran, North Korea, Myanmar, the People's Republic of China, and Saudi Arabia use filtering and censoring software to restrict what people in their countries can access on the Internet. In the United Kingdom, they also use software to locate and arrest various individuals they perceive as a threat. Other countries including the United States, have enacted laws making the possession or distribution of certain material such as child pornography illegal but do not use filtering software. In some countries Internet service providers have agreed to restrict access to sites listed by police.
Document 5: 1201 Third Avenue: 1201 Third Avenue (formerly Washington Mutual Tower) is a , 55-story skyscraper in Downtown Seattle, in the U.S. state of Washington. It is the second-tallest building in the city, the eighth-tallest on the West Coast of the United States, and the 74th-tallest in the United States. Developed by Wright Runstad & Company, construction began in 1986 and finished in 1988. 1201 Third Avenue was designed by Kohn Pedersen Fox Associates and The McKinley Architects. The building was the world headquarters of the financial company Washington Mutual from the building's opening until 2006, when the company moved across the street to the WaMu Center (renamed the Russell Investments Center after the bank collapsed in 2008).
Document 6: Computer security: The question of whether the government should intervene or not in the regulation of the cyberspace is a very polemical one. Indeed, for as long as it has existed and by definition, the cyberspace is a virtual space free of any government intervention. Where everyone agree that an improvement on cybersecurity is more than vital, is the government the best actor to solve this issue? Many government officials and experts think that the government should step in and that there is a crucial need for regulation, mainly due to the failure of the private sector to solve efficiently the cybersecurity problem. R. Clarke said during a panel discussion at the RSA Security Conference in San Francisco, he believes that the "industry only responds when you threaten regulation. If industry doesn't respond (to the threat), you have to follow through." On the other hand, executives from the private sector agree that improvements are necessary, but think that the government intervention would affect their ability to innovate efficiently.
Document 7: Computer security: This has led to new terms such as cyberwarfare and cyberterrorism. More and more critical infrastructure is being controlled via computer programs that, while increasing efficiency, exposes new vulnerabilities. The test will be to see if governments and corporations that control critical systems such as energy, communications and other information will be able to prevent attacks before they occur. As Jay Cross, the chief scientist of the Internet Time Group, remarked, "Connectedness begets vulnerability."
Document 8: Estonia: The Ministry of Defence and the Defence Forces have been working on a cyberwarfare and defence formation for some years now. In 2007, a military doctrine of an e-military of Estonia was officially introduced as the country was under massive cyberattacks in 2007. The proposed aim of the e-military is to secure the vital infrastructure and e-infrastructure of Estonia. The main cyber warfare facility is the Computer Emergency Response Team of Estonia (CERT), founded in 2006. The organisation operates on security issues in local networks.
Document 9: Computer security: On October 3, 2010, Public Safety Canada unveiled Canada’s Cyber Security Strategy, following a Speech from the Throne commitment to boost the security of Canadian cyberspace. The aim of the strategy is to strengthen Canada’s "cyber systems and critical infrastructure sectors, support economic growth and protect Canadians as they connect to each other and to the world." Three main pillars define the strategy: securing government systems, partnering to secure vital cyber systems outside the federal government, and helping Canadians to be secure online. The strategy involves multiple departments and agencies across the Government of Canada. The Cyber Incident Management Framework for Canada outlines these responsibilities, and provides a plan for coordinated response between government and other partners in the event of a cyber incident. The Action Plan 2010–2015 for Canada's Cyber Security Strategy outlines the ongoing implementation of the strategy.
Document 10: Renewable energy commercialization: Just as there is a need for tax shifting, there is also a need for subsidy shifting. Subsidies are not an inherently bad thing as many technologies and industries emerged through government subsidy schemes. The Stern Review explains that of 20 key innovations from the past 30 years, only one of the 14 was funded entirely by the private sector and nine were totally publicly funded. In terms of specific examples, the Internet was the result of publicly funded links among computers in government laboratories and research institutes. And the combination of the federal tax deduction and a robust state tax deduction in California helped to create the modern wind power industry.
Document 11: Computer security: Berlin starts National Cyber Defense Initiative: On June 16, 2011, the German Minister for Home Affairs, officially opened the new German NCAZ (National Center for Cyber Defense) Nationales Cyber-Abwehrzentrum located in Bonn. The NCAZ closely cooperates with BSI (Federal Office for Information Security) Bundesamt für Sicherheit in der Informationstechnik, BKA (Federal Police Organisation) Bundeskriminalamt (Deutschland), BND (Federal Intelligence Service) Bundesnachrichtendienst, MAD (Military Intelligence Service) Amt für den Militärischen Abschirmdienst and other national organisations in Germany taking care of national security aspects. According to the Minister the primary task of the new organisation founded on February 23, 2011, is to detect and prevent attacks against the national infrastructure and mentioned incidents like Stuxnet.
Document 12: Computer security: Public Safety Canada’s Canadian Cyber Incident Response Centre (CCIRC) is responsible for mitigating and responding to threats to Canada’s critical infrastructure and cyber systems. The CCIRC provides support to mitigate cyber threats, technical support to respond and recover from targeted cyber attacks, and provides online tools for members of Canada’s critical infrastructure sectors. The CCIRC posts regular cyber security bulletins on the Public Safety Canada website. The CCIRC also operates an online reporting tool where individuals and organizations can report a cyber incident. Canada's Cyber Security Strategy is part of a larger, integrated approach to critical infrastructure protection, and functions as a counterpart document to the National Strategy and Action Plan for Critical Infrastructure.
Document 13: William Pereira: William Leonard Pereira (April 25, 1909 – November 13, 1985) was an American architect from Chicago, Illinois, who was noted for his futuristic designs of landmark buildings such as the Transamerica Pyramid in San Francisco. Remarkably prolific, he worked out of Los Angeles, and was known for his love of science fiction and expensive cars, but mostly for his unmistakable style of architecture, which helped define the look of mid-20th century America.
