9/25/17 Software Design


This week I picked Joel on Software. The blog lead me to a 20 minute video on how software is changing the future. The video is of Joel talking on software and technology changing the world. He mentions technology and tools we use everyday and the program behind them. For example Uber is a program someone created to call for rides whenever needed. This is a step up from being in the city and trying to hail for a taxi. There is even code written up for something as simple as an alarm clock, allowing the user to decide when the alarm should go off everyday. More complex algorithm ad program are used online for different sites like social media. Facebook and twitter have special algorithm that manipulate certain viewing of post for people to see. The algorithm will put up certain posts to make the user feel happy or angry depending on what the post was about. An example Joel used was someone asking his friend to go to a party with him. The friend could not saying he was sick or to busy to attend. The first person later went on Facebook only to learn his friend went to the party with his ex girlfriend. The post made the person angry. Twitter uses a similar algorithm as well. Twitter pulls up tweets onto the users’ feeds based on if the tweet will make the user happy or not. One user created a fake news post on twitter on busses arriving that held protesters during the election. The tweet went around the site thanks to the algorithm. The tweet even reached the president elect to which he tweeted it but saying that the bus were carrying his supporters for the election. Algorithms used for news site and social media post pages based on the user’s interest. It does not post pages from everyone’s point of view on a topic just the certain point of view that the user prefers and wants to learn more about. Joel also talks about the site Stack overflow, which he created to help programmers with their programming. There users post question about a piece of code that they are working on and other users can comment and correct the code or give advice where needed.

I liked this blog a lot along with the video. I liked how he talks about various sites that people use everyday and the coding and program behind them. This explains how different sites work and a warning to not fully believe in the story or news that are posted. This gives an insight of how software and programming is changing the future of our world and what to expect from it.
