1/26: The Internet, World Wide Web, Wi-Fi and Bluetooth

     Every day, we mindlessly scroll through our phones and use technology without a second thought. As a Gen Z, I take for granted that only 30 years ago this type of accessibility and the era of social media was seemingly much obsolete. Computers were just giant calculators and only used by the people who created them or were rich enough to buy one. Now, smartphones have more computing power than the rockets that sent people to the moon. Now, we use int internet and World Wide Web without even knowing how it was created and who created it. As far back as the 1900’s people like Nikola Tesla and Guglielmo Marconi wanted ways to connect with people around the world without using wires.

    Then, the World Telegraphy system was created as a global network in the 1900’s. In the 1970’s two engineers, Robert Kahn and Vinton Cerf began inventing the modern-day Internet and coined the names The Founding Fathers of the Internet. They originally created this idea because they wanted to be able to communicate- they basically created a set of guidelines called TCP/ IP which is the backbone for an efficient and large web of interconnected networks—thus the name “Internet.” In 1990, Tim Berners Lee created the early technologies of the modern-day World Wide Web which included HTML, URI, and HTTP. By the end of this year, all people were able to access what is known as the Web.

    Basically, the internet is a network of networks, and the web is a system we use to access the internet.  The internet can exist without the web but not vice-versa. The internet is the hardware, machines, and data and the web is what allows us to access this technology and use it the way that we do. Tim Berners-Lee also created the first website: http://info.cern.ch/hypertext/WWW/TheProject.html . It is still up today and can be accessed by anyone. 

To make the Internet accessible we need to be connected to Wi-Fi. Hedy Lamarr, an actress from the 1930’s doubled as an inventor who pioneered the technology that would soon be the foundation for Wi-Fi, Bluetooth, and GPS. Although she was not accredited for her inventions until later, others were able to expand her research and modernize her ideas. The real inventor of Bluetooth is actually a group of men who worked at a company called Ericsson.

    The team included Jaap Haartsen and Sven Mattisson. In fact, Bluetooth coined its name from one of its team members, Jim Kardach who was reading about Vikings at the time of his work borrowed the name Bluetooth from the second King of Denmark- Harald Bluetooth. He drew his inspiration from King Harald's ability to unite Scandinavia just as Kardach would unite PC and cellular industries with a wireless link.

    Moreover, the logo was a combination of “H” and “B” as a tribute to the late king. Similarly, Wi-Fi has an origin story but one that is much more basic. With its standards being IEEE 802.11., its creator Vic Hayes agreed it needed a better name. Working for the Wi-Fi Alliance, someone proposed “Wi-Fi” which also sounds a lot like hi-fi (high fidelity.) It was way catchier than its actual name and it stuck. As far as its logo, it is based on a yin-yang to represent W-Fi’s certification of a product for interoperability.

4/18: Somewhere

Image
      For this assignment I was very excited to be able to photoshop myself into one of my favorite movies. I really enjoyed being able to choose the scene and make it my own. I really had a fun time utilizing the various tools and techniques we used in photoshop. Before shooting my photo, I looked at the lighting and overall color of the image and tried to recreate it. There is a lot of natural light in the photo so I shot my picture in daylight and also used a LED lights to replicate that glow in the photo. I found this project to be very enjoyable and not too hard. It was fairly easy to take the picture and decide where I wanted to crop myself in. I had trouble adjusting my body size because my head had to be proportional to Timothee Chalamets and also the book I was holding had to be comparable to the books on the ledge. Because I got the lighting pretty much spot on, and the magnetic lasso tool made it easy to cut myself in, the only thing I really had to play a...

4/6: Tagbrush Logo

 This project was particularly tough for me to figure out but now that I have this brush option, I understand why we completed this. Its a rally fun and easy project once you are finished as it is stylizes your logo to make it stand out on your artwork. Now that I have this brush downloaded onto my folder, I think it is a really unique way to suggest the artwork is mine.  At first, I found this project to be a bit difficult. Although there were a lot of steps, after reviewing the directions provided and completing them one step out of a time, it became a lot easier. I really enjoyed seeing how my logo came out in this stylized matter I think it gave it a really unique look.
