Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

What evidence does Google present for Chinese government censorship? How does this impact the Jasmine revolution? Describe LinkedIn. Why was LinkedIn disrupted?

1. What evidence does Google present for Chinese government censorship? Google says that Chinese customers and advertisers have increasingly been complaining about their Gmail service in the past month. Attempts by users to send messages, mark messages as unread and use other services have generated problems for Gmail customers. Google shows potential signs that the Chinese government is increasing their censorship by revealing that Gmail's e-mailing system features have been disrupted for Gmail users as well as other Gmail interfaces such as sending e-mails. Google also reveals that the users who filed in these complaints are mostly potential threats to the Chinese government such as the activist accounts also with financial, technology, media and chemical companies users' accounts. Thus, even though there is no concrete evidence, there are signs that are most likely to be linked to the Chinese government. 2. How does this impact the Jasmine revolution? The move follows extensive attempts by the Chinese authorities to crack down on the Jasmine revolution, an online dissident movement inspired by events in the Middle East. The censorship was supposed to prevent people from getting too much information but instead, this can provoke people to go against the government since people are aware that they have been treated unfairly. 3. Describe LinkedIn. LinkedIn is a business-oriented social networking site. LinkedIn operates the world's largest professional network on the Internet with more than 100 million members in over 200 countries and territories. The purpose of the site is to allow registered users to maintain a list of contact details of people they know and trust in business. The people in the list are called Connections. Users can invite anyone to become a connection. 4. Why was LinkedIn disrupted? LinkedIn is business-social networking and Chinese can use this site as the means of evoking opposition against the government. China's president Hu Jint

manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.
