Calculating Binary Number
December 15, 2008
Binary works on “base two” which contains the of digit of 1 and 0. “Base Ten” is 0-9 which we use every day.
Base 2 = Binary = 01 (2 digits)
Base 10 = 0123456789 (9 digits)
Binary uses the exponential form of 2 like 2^0, 2^1, 2^2…. Also binary works from right to left instead of our regular left to right that we read with.

2^0=1, 2^1=2, 2^2=4, 2^3=8, 2^4=16, 2^5=32, 2^6=64, 2^7=128, 2^8=256

Each base is 1 bit, and 8 bits like the table above equals to 1 byte.
1024 bytes are 1 kilo byte.

By using the table above, you can convert base 2 to base 10 and base 10 to base 2. To convert base 10 to base 2, just convert the base 2 digits until it equals the base 10 number.
Obama uses technology during electoral campaign
December 15, 2008
Barack Obama used technology as an advantage during his electoral campaign. He came up with many creative ways to connect with the people especially with teens. The McCain and Obama campaigns have heavily used the Internet and other technologies but Obama is the leader who effectively used it as an advantage. The amount of technology and the use of internet have never been surpassed compared to any advertising in the history of humankind.
Obama is the only presidential candidate to buy ad space in video games. He placed in-game ads on eighteen games, including “Guitar Hero” and “Madden 09″ from the Obama campaign that appear on billboards and other signage during the duration of the game. Obama also used Apple’s iPhone as an advantage to let his supporters know that about the latest news about his campaign.
Obama and Mcain both used “social media”; making use of social sites such as facebook and myspace. The Obama campaign had official presence on 16 networking and information sharing websites. Some of these include photo sharing sites like flickr and networking sites such as LinkedIn.
Obama’s campaign website provides registered volunteers a detailed script and a list of voters to call. These voters are largely from swing states and volunteers have the option of selecting the state they want to call. The candidate websites have also developed since the last elections and both McCain and Obama have campaign websites that act as one-stop shops for supporters. The website of Obama includes and his views on various issues, it also provides online volunteer registration and online fund contribution. Obama’s official website Barackobama.com has sections addressing specific groups. His site also has an “Obama-Biden Tax Calculator” where you can find out how much tax cut to expect if Obama wins.
Barack Obama has clearly used technology as an advantage during the election and it heavily contributed to the outcome of the election. Both the candidates have established a new way of electoral campaign by using technology to acquire supporters for the election.
