One application where I don’t think AI would be very useful is for therapy. Therapy is an extremely emotional and complex subject. Often in therapy there is no one right answer. When therapist work with their clients they must be able to evaluate emotions, understand body language, and interpret reactions to their questions. Although AI is good at a lot of things, understanding emotions and the human phycology is not one of them. A person like a therapist is able to connect emotionally with their clients. People have their own stories and can make their own relations with other people though similarities in past experiences. A computer model like AI does not have feeling or emotion, and certainly doesn’t have any past experiences to relate with.

Even though AI is an incredible to with nearly limitless amounts of potential, it must be said that it can’t do everything. AI does not posses the emotion capacity required to fill the role of a therapist.

The LSB holds the least weight when determining the color/intensity of a pixel. When we modify the LSB the appearance of the pixels changes insignificantly, therefore the human eye is unable recognize any difference. An image file is made up of pixels which contain three different bytes corresponding to the colors Red, Green, and Blue. LSB steganography changes the last bit to hide just one bit of data within that pixel.

Hiding text in an image is done by converting the message into binary. each letter of the message is converted to its binary code of 0s and 1s. The sender then then selects and image to be used. It is important that the image is large enough (has enough pixels) to accommodate the message without changing the image visually. Then the pixels are read into the image and the LSB is modified for each value. Once the image is saved, you now have an hidden message in your text.

LSB steganography can be utilized in many applications such as security/military purposes to copyright and watermark protection. Steganography is fascinating tool used in digital media for both art and war.

ChatGBT Prompt:

How can steganography be used to hide text in an image by modifying the least significant bit?

ChatGBT Response:

Steganography is the practice of concealing a message within another medium, such as hiding text within an image. Modifying the least significant bit (LSB) of the pixels in an image is one technique commonly used for this purpose. Here’s how it works:

1. Binary Representation of Pixels: In digital images, each pixel is represented by binary values. In an 8-bit grayscale image, each pixel value ranges from 0 to 255, and in a 24-bit color image, each pixel typically has three color channels (red, green, and blue), with each channel represented by 8 bits.
2. Least Significant Bit: The least significant bit (LSB) is the rightmost bit in a binary number. It holds the smallest value and contributes the least to the overall value of the pixel. Modifying this bit has the least noticeable effect on the appearance of the image.
3. Hiding Text: To hide text within an image using LSB steganography, you can replace the LSB of each pixel with a bit from the binary representation of the text you want to hide. Since the LSB contributes the least to the pixel value, this alteration is generally imperceptible to the human eye.
4. Encoding and Decoding: The sender encodes the text message into binary and replaces the LSB of each pixel in the image with a bit from the binary message. The receiver then extracts the hidden message by reading the LSB of each pixel in the image.
5. Considerations:
   • The length of the text message should be small enough to be hidden within the image without significantly altering its appearance.
   • The choice of pixels to modify can affect the robustness of the hidden message against image manipulation or compression.
   • Encryption can be combined with steganography to enhance security and prevent unauthorized access to the hidden message.
6. Tools and Software: Various software tools and libraries are available for implementing LSB steganography, including Python libraries like Stegano and OpenStego.

It’s important to note that while LSB steganography can effectively hide messages within images, it’s not foolproof, and sophisticated analysis techniques can potentially detect the presence of hidden data. Additionally, always ensure that the use of steganography complies with legal and ethical guidelines.

Think to yourself the last day you went without using something digital. It is almost impossible. You wake to an alarm on your phone, you get the weather and daily news using your tv, you grab food from your fancy digital fridge. I mean even some toothbrushes are digital. Its no secret that the entire world is going digital, and for good reason. Things being digital are convenient as heck.

In my Digital Revolution class, we learned of three major advantages to things being digital. Digital computers are exact, repeatable, and robust to noise, but what do all these things mean? For a digital computer to be exact, that means it uses precise mathematical rules when operating. For example, the user inputs a specific instruction that can be computed with reliable calculations and consistency. The exactness is what allows us to rely on the information in which the computer produces. Repeatability on the other hand, lets us trust what is actually being computed. When a user inputs a the same function, recognize and repeat itself allows us to trust the system. If you know anything about coding, you will know that algorithm is a step-by-step program which executes line by line. This design ensures a reliable and repeatable product. Finally, digital devices are robust to noise which means they are uninterrupted by unwanted transmissions. By utilizing binary code, digital devices are able to reliably interpret these messages and cut out unwanted frequencies. These three advantages combined help to make digital the ideal choice for computers.

When talking about digital computers, the conversation is usually all about its pros. However, its import to note that they are some draw backs within the digital world. For starters, our entire economy, government, and infrastructure all rely on digital computers for many applications. God forbid we go to war, we are just one EMP (Electromagnetic pulse) or cyberattack away from all those things being corrupted. Our significant dependency leaves us incredibly vulnerable to malicious intentions. Our incredible dependency also create knowledge gaps. I mean this in the sense that, because so many things are automated and done for us we forgotten to do simple everyday tasks. This dependency could lead to generations of people that just simply don’t know how to function without it.

Overall, digitals computers provide an incredible advantages in terms of reliability, and making many aspects of life much easier. Although there are some draw backs, it is clear that society will continue to push the envelope with what is digitally possible.

              The invention of the telegram was motivated by a need for a faster and more effective way of communicating over long distances. The telegram helped with all aspects of life, from business, government, military, and recreation. Prior to its invention, messages were sent via horse and messenger. This method was painfully slow and inefficient, that was till 1838 when Samual Morse and Alfred Vail unveiled the electric telegraph. The original version used morse code to transmit dashes and dots which would represent numbers and letters. This new form of rapid communication served as the breakthrough for economic development. When it comes to driving factors, humans played a very crucial role in the development of the telegram. Humans developed a need for more organizational capacities in the world of business. Humans also had to operate these telecommunication lines which led to a need profession of telegraph operators.

              When it comes to the technical make of the telegram, an analog system would not have been ideal. An analog system relies on continuous signals which are susceptible to interferences, especially over long distances. A digital telegraph and the use of morse code provided a stable and reliable form of communication. The telegram started to come down from its peak as newer forms of communication were invented. As the telephone and fax machines began to become more popular, telegrams quickly became outdated and slow.

 Today, humans can communicate almost instantaneously through devices they have in their pockets. Telegrams are a thing of the past, now only found in museums.
