An invention that could change the internet for ever
A Silver Ooze That Could Shrink the iPod
http://bits.blogs.nytimes.com/2009/05/01/a-silver-ooze-that-could-shrink-the-ipod/
I think the Kindle is significant because it can really change the portability of having books. You will be able to read hundreds of books using 1 electronic device
Also, I think the idea of having a slimmer iPod is a great idea. It would be more portable. They would find a technique for cramming large amounts of flash memory into a tight space. By using Vertical Circuits’ technology, device makers can fit lots of high-speed memory into their products and leave more room for bigger displays and larger batteries.
Google Sketchup
May 4, 2009
Google SketchUp is a fast, flexible, and fun 3D modeling application that allows you to quickly mock up designs of objects, buildings, or anything else you want. You can use SketchUp for fun to draw three-dimensional virtual neighborhoods or for practical projects, such as renovating a kitchen or building a bookshelf. Google broadens the power and novelty of this program by enabling you to share your creations with the public online; just upload your designs to Google’s 3D Warehouse Web site or drop them into Google Earth. In turn, you can view models made by other SketchUp users and save them to integrate into your own designs.

BeOS
BeOS was an operating system for personal computers which began development by Be Inc. in 1991. It was first written to run on BeBox hardware. BeOS was optimized for digital media work and was written to take advantage of modern hardware facilities such as symmetric multiprocessing by utilizing modular I/O bandwidth, pervasive multithreading, preemptive multitasking and a custom 64-bit journaling file system known as BFS. The BeOS GUI was developed on the principles of clarity and a clean, uncluttered design. The API was written in C++ for ease of programming. It has POSIX compatibility and access to a command line interface through Bash, although internally it is not a Unix-derived operating system.

Google Latitude
March 3, 2009
“Google Latitude”
“Google Latitude allows you to share your location with friends and view their locations on a map. Latitude is completely opt-in, so you must enable it before you can start sharing location and can disable it at any time. Google Latitude is a new feature for Google Maps on your mobile device. It’s also an iGoogle gadget on the computer. Once you’ve opted in to Latitude, you can see the approximate location of your friends and family who have decided to share their location with you. And with Latitude, not only can you see your friends’ locations on a map, but you can also be in touch directly via SMS, Google Talk, Gmail, or by updating your status message. To use Google Latitude and accept location sharing requests, you must sign into Latitude using a Google Account. Google Accounts include Gmail usernames, Google Accounts you’ve created for other email addresses, and Google Apps accounts.”
Possible Privacy concerns
The sensitivity of location data can violate privacy. However, with this you not only control exactly who gets to see your location, but you also decide the location that they see. Everything is under your control and, of course, you can sign out of Latitude at any time. Google Latitude notifies the user of the device that it is sharing the location of the device. The service allows the user to decide how much information to submit, who to, and also allows the user not to share any information at all. The negative effect of Google Latitude allows the user to control their privacy settings when they are running Google Latitude, what if the user doesn’t know they are running it? It is the concern that Privacy International has been raising. As the program doesn’t notify the user that it is running, depending on the situation, the user could be completely oblivious to the fact that their location was being broadcasted to whoever the employer set it up to broadcast to.
Concerns of my image being added into social networking sites
Getting my pictures added into social networking sites is dangerous. Other people that I don’t know can see my latest pictures and see what possessions I might have. I also risk getting my identity taken by someone who wanted to use my picture and using it to meet my friends and family.
Possible implications of Facebook privacy concerns
On Facebook, things such as, photos, images, wall-to-wall’s can be publically placed on the news feed, where strangers are able to stalk the people they want. Secondly, if you don’t put the privacy “lock” on your facebook (like me) random strangers are able to look through your profile as if they were your “friend.” Secondly, your bosses at work are able to see what you’re up to, and they may even judge you from what they see on your facebook. Also, when facebook asks you to put your email, or mobile number, or your work place, or birth date and current school, it is very easy to be tracked down.
Website Process
February 6, 2009
Http (Hypertext Transfer Protocol) – provides a standard for Web browsers and servers to communicate. The definition of HTTP is a technical specification of a network protocol that software must implement. HTTP is an application layer network protocol built on top of TCP. HTTP clients (such as Web browsers) and servers communicate via HTTP request and response messages. The three main HTTP message types are GET, POST, and HEAD. HTTP utilizes TCP port 80 by default, though other ports such as 8080 can alternatively be used.
DNS (Domain Name System) - In Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they’re easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn’t know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
IP (Internet Protocol) – IP specifies the format of packets, also called datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP by itself is something like the postal system. It allows you to address a package and drop it in the system, but there’s no direct link between you and the recipient. TCP/IP, on the other hand, establishes a connection between two hosts so that they can send information back and forth for a period of time.
Traceroute – A utility that traces a packet from your computer to an Internet host, showing how many hops the packet requires to reach the host and how long each hop takes. If you’re visiting a Web site and pages are appearing slowly, you can use traceroute to figure out where the longest delays are occurring. The original traceroute is a UNIX utility, but nearly all platforms have something similar. Windows includes a traceroute utility called tracert. In Windows, you can run tracert by selecting Start->Run…, and then entering tracert followed by the domain name of the host.

Binary Numbers Part 2
February 2, 2009
| Hex | F | E | D | C | B | A | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
| Binary | 1111 | 1110 | 1101 | 1100 | 1011 | 1010 | 1001 | 1000 | 0111 | 0110 | 0101 | 0100 | 0011 | 0010 | 0001 |
Converting Binary to Hexadecimal…
1 10 – A
211 – B
3 12 – C
4 13 – D
514 – E
615 – F
You’ll typically see hexadecimal numbers preceded by 0x, it just means that the number is hexadecimal, but the actual 0x is irrelevant to the number. So 0×42FE means that 42FE is a hexadecimal number, we know that because of the 0x, ignore the 0x when you’re actually working with the number.
Converting from binary to hexadecimal is very easy, you first separate the binary number into 4 bits. For example, the number 20, which is 00010100 in binary, you would set it up as 0001 0100. Then, what you do, is you convert each nibble into decimal, for example, for the first nibble, 0001, since it equals one in decimal, you would then convert the decimal into hexadecimal, and since in hex 1 is 1, you would write 1. Now, for the second nibble, 0100, in decimal is 4, and in hex its 4, so 0001 1000 in hexadecimal is 0×18.
To convert from hexadecimal to binary, all you do is get the number. We then read from left to right, or right to left, it doesn’t matter, as long as we maintain the order. Do it from right to left. If the first digit is 0, and in binary 0 is 0000. Note that each digit in hexadecimal is 4 bits, so even though we can express 0 in 000000, and also 0, we have to fill up 4 bits, so it would be 0000.
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.
Base Two
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

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.

3 Stories
1) Is Your Username Taken? Usernamecheck Will Tell You.
People tend to use the same username when signing up for an account, but sometimes you might not remember if you have signed up for this website or if someone already has the same username. I found Usernamecheck very useful because it allows you to check usernames for websites and see if people have the same username as the one you want to use. Also, Usernamecheck is a helpful tool because people will know which one they have once signed up for but have forgotten about.

2) Google Earth comes to the iPhone
Apple’s popular iPhone have recently launched Google Earth software for the iPhone. It is available in the iPhone App Store. I think the Google Earth on the iPhone is very useful because it provides portability to check maps and directions without using a GPS or a real map. It would really help a person who doesn’t want to buy a separate GPS when one has an iPhone that is capable of doing things that a GPS can do. Google Earth allows you to fly to the far reaches of the world from the palm of your hand.

3) Mitsubishi beams out first laser-powered TV
Mistubushi have recently announced the first laser powered television. The LaserVue L65-A90 is a 65-inch projection that uses DLP technology that is supposedly to deliver a very clear and crisp colour depth. The A90 comes ‘3D Ready’, but most probably there will be a few games that make use of it in the future. It will revolutionize technology and every company will want to make a TV that is laser-powered to compete with the LaserVue L65-A90.
