New Barcodes use light to store data

Ever wonder why they don’t make barcodes easier to read on packages? Sometimes it takes several tries to get a bag of chips to blip. But at MIT the barcode is getting a makeover. Using a small lens (3mm) and LED the new Bokode stores ridiculous amounts of data in a 3D optical layering. The best news is this new optical barcode can be read from up to several meters away meaning no more waiting in line while the store clerk tries countless times to scan those chips.

The Process of Learning a Word

Deb Roy studied the environment around his child to see how he learns a new language and how that develops over time. What I found interesting with this idea was the methodology he used to conduct this research. He documented the process over time in such a way that he was able to filter out the words that the baby heard the most and the people he was around the most. Based on this, he was able to diagram a process of his language learning. He used simple technology such as camera around the house. However he was able to extract the data that was relevant to his study.
