Explain the issue with Path. Evaluate Apple's solution.  Should services such as Path take or hold our data? all feb 21 johnroy

Explain the issue with Path. When you take apps by log in from your iOS device then it would take you personal information and put it into the Apple server. It does this without permission of the user. The reason why is doing this to locate the user where you are at and your friends. Evaluate Apple's solution. Their solution is just to add new feature so you would be aware that apps would take your private information and put into the main server apple server. When you're downloading or getting apps you need to approve that they get you privacy information. Should services such as Path take or hold our data? I believe that they shouldn't because it's hard to trust large companies. The information that they have could be sold to other person that interest about your privacy. Another possible solution is that the data that is stored could be hacked anytime and when this occurrence happens. The hacker can sell my privacy to someone or he directly knows where I live, what's my name and etc.

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

Agree or disagree? all feb 10 soobin

Agree Agree to some extent. Internet freedom can be sacrificed only to a certain extent to fight piracy. Getting rid of internet freedom is basically the same thing as shutting out the communication lines of the world. The source of the reason why piracy is done is mainly due to the fact that people can't afford the items that they wish to use, or need to use, because they are ridiculously overpriced. These industries don't think that way because they want profit, however, if piracy was stopped, then no one will buy their products anyways because they still can't afford it. Popularity of the product will decrease, and the marketing of the product basically just failed. We need to compromise something so that piracy is decreased until there is no more. But suddenly stopping everything in one shot with something like SOPA isn't the way to go. Disagree I disagree. The internet should be free and open. We need to educate people not to download pirated software, movies and music. Doing so is the same as stealing from a shop, which most people would not do. Most people would be prepared to pay small amount for the right to download these things. If governments try to remove websites, it is the same as censorship which sometimes happens in dictatorships but should not happen in free societies. We really need freedom for the internet, so that we can easily share our own ideas, and thoughts. Unlike China, where people can't even talk gossip about governments, which is a basic human right. But China is still very famous for internet piracy. The United States should not have the power to prevent freedom of internet because they are not the world's police force. They should not have the power to dictate what happens in the rest of the world. That's why internet freedom should not be sacrificed.

Would you try a new network? all feb 10 nat

Personally I wouldn't try new networks, unless I have friends there. A lot of my friends are focused on Facebook, and I don't mind sharing my content with people I am friends with, as I usually decline requests from strangers, and are friends with people who I actually know or have mutual friends. However, I wouldn't mind giving Pinterest a go, as I think it sounds interesting, and also it sounds like Tumblr, which I like a lot, because we can share images with people with the same interest.
