MIT Media Lab researchers have developed a wireless system that leverages the cheap RFID tags already on hundreds of billions of products to sense potential food contamination.


"Putting food-safety detection in the hands of consumers

Simple, scalable wireless system uses the RFID tags on billions of products to sense contamination."


Media lab researches have developed a wireless system that leverages the cheap tags on food and can sense potential food contamination. 
With the simple, scalable system, the researchers hope to bring food-safety detection to the general public.The researchers’ system, called RFIQ, includes a reader that senses minute changes in wireless signals emitted from RFID tags when the signals interact with food. For this study they focused on baby formula and alcohol, but in the future, consumers might have their own reader and software to conduct food-safety sensing before buying virtually any product. 

I believe this is the perfect invention. There are many people who don't have a lot of resources and will eventually eat what they can afford. Sometimes that food isn't in the best conditions and people could fall sick; with this new invention, it can be easier for people to detect which food is good to eat and which isn't. People can even eat healthier food and the rate of healthy people can go up.

Difference between 300ppi and 72ppi

   When you need to print a picture, you need a 300ppi resolution in order for it to have a high resolution and for it to look professional. When you are inserting a picture in a webpage, you need a 72ppi resolution so it doesn't look too bright. For example, when printing out the two pictures, the one with 300ppi resolution was a good picture because since it had a high resolution, you were able to see the picture clearly as if it was a regular picture and not something that was printed. Compared to the 72ppi resolution, which was too dim and you weren't able to distinguish things very clearly.

Lab 6 Reflection

For lab 6 we had to use what we learned in lab 4 to animate a box in the same way. I t was basically like a redo of lab 5 but with a stop button included. Although, in this lab we had to include a “stop” button which, when pressed, will stop the animation currently in progress. For example, if you clicked on the move animation, originally, the box would move from its initial position to wherever it’s ending position is. With the stop button you can stop the animation halfway through so the box only moves halfway to were it was supposed to be. The set up for this is the same to the lab 4. First, we create the stop button in HTML whilst giving it an ID so that we can call it with a JQuery selector. In your javascript file you add an event listener to the stop button. Then if the button is pressed you use the built in JQuery function “.stop()” which stops the animations.

CTE Expo

CTE expo is a way for communicating to the freshman. As well as to show the freshman what we do in the web design academy. To prepare, we created a board showing off the business cards which is one of the many projects that you do In the first year of the web design academy. I presented my board a few teachers and some students in order to receive their attention.  I was able to convince a few students into joining the web design academy. And I was able to present without surprisingly having a anxiety, hehe. In order to improve, I can include more information about what the academy is about and how it is based on my current experiences. I felt that it went very well and a bit as planned
