Excellent article describing in very layperson terms how a HTTP cache works. Also, a great pointer to an online diagramming tool.
Obama wins! Who would have ever thought that a black man named Barack Hussein Obama would be the President of the United States. The ripple effect of this is going to be so fundamental to the social and political fabric of this country. He, in the truest sense of the word, epitomizes hope and change. This is a strong signal that the US people have sent to the world. After 8 years of carnage by the Bush administration, the people of the US have signified that change is at hand. Some skeptics would argue that he is just a politician and that the system is too big for him to change. This view is one that underestimates his mere presence in the highest office of the land.
He will undoubtedly be held to a higher standard than his predecessor and there will be divisive racial politics to deal with. But Obama is above all of that and can handle it with dignity and aplomb as has been witnessed by his campaign over the past 2 years.
Last year when I was in Australia and after watching Michael Moore’s movie Sicko, I began to really wonder what was holding me back from emigrating to a country that placed the aspirations of the masses over the interests of a select few. While visiting India and talking politics with old friends, I could only share in their criticism of US foreign policy and the catastrophe of the Bush administration. Now, with this election, I feel redeemed and no longer think that fleeing the US is the answer. As I grow older, I also am developing a stronger sense of nationalism and Obama does indeed contribute to that. Lastly, yesterday evening when it looked like Obama would win, I told my 4 year old son, "You know what an Obama victory means? It means that even you, someone named Dhruv Mahendra Rao, could become President of this country." What a changed and better world we live in now.
