News summary for September 21st by Stefan Saroiu. All articles come from NYT. 1. "Costly, Sure, But It's Nirvana for TiVo Fans" Summary: ========= TiVo is coming out with support for HDTV. Its newest box can hold 32 hours of HDTV (ouch!) or 200 hours of standard TV. It costs $800. Implication: ============ Time-shifting TV is here to stay. Observation: ============= The reason why YouTube is spending a lot of bandwidth to deliver content is because it delivers content only when a user requests. A different way to deliver content on the Internet is to build a broadcast system (something like Digital Fountains) and to equip clients with large caches (their TiVo). The amount of bandwidth consumer by YouTube would be constant over time. Idea: ====== Build a YouTube system like TV + TiVo. 2. "Effort to Combat Child Pornography on Internet would Close Sites" Summary: ======== The US Congress has convinced ISPs to report cases of child pornography. Several ISPs have already agreed: AOL, Google, Microsoft, EarthLink. Several financial companies have also agreed to track the child pornography customers and websites through their use of credit cards. Observation: ============ There are several reasons why legislative measures to combat technological problems have traditionally been infective. First, the rate of change in technology greatly surpasses the rate of change in laws (the law cannot keep up with technology change). Second, many of these illegal activities, like child pornography, spyware, phishing have always had a hard time to define properly ("I don't know what pornography is, but I know it when I see it".) Third, the Internet is an international network and US's laws only have limited jurisdiction. Question: ========== If child pornography can be addressed by the US Congress, could the Congress also address phishing? Are these problems similar enough? 3. "Many Theories on Income Inequality, but One Answer Lies in Just a Few Places" Summary: ======== It is well know that income inequality (or the gap between the poor and the rich) has grown in the '90s. It has been thought that the reasons for this gap widening are due to declining unionization, outsourcing, immigration, etc.. A recent study has shown that this growth is due only to four US counties (out of 3100): Santa Clara, San Mateo, San Francisco, and King County (Seattle/Redmond). Implication: ============= The IT industry has had an enormous impact on society in the '90s. It managed to create wealth in a hugely disproportionate way compared to the rest of the industries. Another implication is that income inequality is also accompanied with geographical inequality. Wealth is not distributed geographically uniform.
