That’s right. No extra data, no changes to the image. All the pixels and colours are exactly the same. Any data you want inside a GIF without any trace. But how? I’m glad you asked.
During highschool I was interested in steganography, the study of hiding messages in plain sight.

However, there is an area of education swiftly rising in competition and rankings: Canadian technology universities. Universities like the University of Waterloo have been making global headlines for their billion dollar startups and excellent tech programs.

Often times the word “data” is synonymous with “fact”, however, there is an intermediate step for this conversion. Facts are created by looking at data and extrapolating causality.

You can learn about how to make your first webpage or how a Mosfet transistor works. This incredible span of topics creates a problem when the idea of “learning technology” or “working in technology” is presented.
Determining what range of knowledge is required is a constant problem in technology…
