Current Events #13 (MP3 #4)

     A computer processor, or CPU, is a small but very significant chip inside a computer. It is responsible for executing instructions of computer programs and dealing with inputs and outputs. CPUs have always gotten smaller in size yet doubled in speed every 2 years by increasing the amount of transistors in the build (Moore's law). The future of the CPU may not be in getting smaller, however, with Intel's latest announcement of their new product. The Foveros chip will be the first 3D stackable chip to be implemented in the industry. The design philosophy of the chip is dividing key elements of a CPU into sections known as 'chiplets' and making processing components stackable and a premade chip die/mold. The benefits of this philosophy increase power and efficiency of a CPU but also help make it viable to make chips at a 10nm scale, something Intel has faced many bumps in the road doing. The different sections of the processor are made in a process called 2D stacking; essentially the different parts are made using a different node.
     Intel also announced a side project named Sunny Cove. It is a processing architecture that Intel claims will decrease latency and and allow more operations to be conducted simultaneously. Another new project is the new Gen11 integrated graphics, designed to surpass 1 teraflop, which will be part of the Foveros chip. Many questions are raised by the recent announcements, such as if Sunny Cove will have Foveros style chips or not and if the new Foveros chips will be used in smartphones and other mobile devices along side traditional computers. While Intel says that mobile devices are included in the range of devices the Foveros can operate in previous attempts with developing smartphone procesors suggest otherwise.
     My personal reflections are that processors are continuing to get more powerful but perhaps the idea of getting smaller has been ditched. In recent years it seemed like Moore's law would become obsolete, many CPU manufactures saying it was no longer their goal. Building up, instead of increasing transistors per inch and becoming more compact every two years, may keep part of Moore's law alive. It allows for a new, maybe even easier, way to double CPU speed every two years without the stress of making everything so small. The result is the continuation of Moore's law in a way that Gordon Moore probably didn't imagine. I am also eager to see the boost in performance computers get from using this processor. Just how faster will my computer run programs and how many can I run at a time are among the many things I excited to see will be affected by the capabilities of this processor.

Favicons

Image
     Favicons are small square graphics, ranging from 17 x 17 px to 28 x 28 px in preferred size, that give a graphical representation of the site the user is visiting. The favicon appear in the address bar on the left. The main reason websites use favicons is to improve their user's experience. Favicons, by giving a graphical representation of their site, make it easy for the user to recognize the site they're on while they might be switching tabs or scrolling through a list of bookmarks. A favicon adds to a website's uniqueness by making it stand out and different from other sites through use of graphics.      To create a favicon you need a favicon generator, a software where you can design your favicon. Sites may be owned by businesses that have logos to represent themselves but when it comes to favicons simply converting the image file for the logo into a .ico (file format that favicons use) may not be optimal. Favicons have a limited size, biggest siz...

Favorite Teacher Project Reflection

Image
     The second project for DD this year was about creating a website in appreciation of your favorite teacher. This project was a lot like the our first project except it revolved around a teacher and not movies, otherwise, it required all the same skills we learned in the first project. Just like in the first project, the beginning steps were not in the computer, rather, they were on paper. After deciding which teacher to make the site about (Ms. Sakhno), I begun by creating wireframes both of the website itself and how the folders for the project would be organized. My website wireframe consisted of 4 pages all with relative links that took the user to all the other pages from any single page. There was a home page, which explained the purpose of the site and why the teacher I chose was my favorite, a biography page, which described the teacher's life up until now, a subject page, which discussed the subject the teacher taught, a trivia page, which displayed an infog...

Lab 20 Reflection

Image
     Lab 20 incorporated many of the things we learned from Lab 18, with the functionality holding many similarities. In Lab 20 we were to create a webpage that compares 2 numbers, x and y. The user is supposed to be able to see if x is greater than y, y is greater than x, x and y are equal, etc. The interface is similar to Lab 18; there is an area to input two values, there is an area with many buttons that lead to a specific outcome, and there is an area to view what the outcome is. Unlike Lab 18, the buttons don't perform an arithmetic operation on the 2 values but check if a certain comparison between the 2 values is true or false. The result area, instead of displaying the result of an arithmetic operation done on 2 numbers, displays if a certain comparison between 2 values is true or false, essentially displaying the result of clicking the now comparison buttons.      I started Lab 20 just like I started Lab 19, by duplicating the code for Lab 18.
