Robert Frost - 1874-1963

Two roads diverged in a yellow wood. And sorry I could not travel both, And be one traveler, long I stood, and looked down one as far as I could, to where it bent in the undergrowth.

I took the other, as just as fair, and having perhaps the better claim, because it was grassy and wanted wear, though as for that the passing there, had worn them really about the same.

And both that morning equally lay, in leaves no step had trodden black, oh I kept the first for another day, yet knowing how way leads on to way, I doubted if I should ever come back.

I shall be telling this with a sigh, somewhere ages and ages hence, two roads diverged in a wood, and I, I took the one less traveled by, and that has made all the difference.

Data Gathering Methods

Physical Data Gathering Methods

1. Notes

   • Pros: Good overview, flexible, less intrusive, aids focus.
   • Cons: Can be difficult and slow, requires concentration, potential for bias.

2. Audio/Video Recording

   • Audio combined with photos can add valuable context.
   • Requires explicit permission from participants.
   • Raises potential privacy issues.
   • Requires good quality recording equipment.

Data Gathering Techniques

Surveys

Recruitment

• Define the target population clearly.
• Gather relevant demographic information.

Sampling

• Probabilistic Sampling: Each member has a known probability of being chosen.
  • Example: Census.
  • Random Sampling: Every individual has an equal chance.
  • Stratified Sampling: Ensures representation from each subset of the population.
• Non-probabilistic

To start a backend project.

- npm init

Then make a file with whatever entry point you named it as, for example, server.js

Once package.json is created:

• npm i <package>
• connect-mongo (store sessions in DB)
• dotenv (for config files, environment variables)
• express
• mongoose
• express-sessions (sessions and cookies)
• method-override (to use PUT, UPDATE, DELETE requests)
• moments (date formatting)
• morgan (logging)
• passport (authentication)

npm i -D <package>

• nodemon (Update every file change instantly without having to restart the server)
• cross-env (To update environment variables in script definition itself)

After installing the dependencies, edit the scripts in package.json

High School Reflections

High school has given me very good and not so good moments, but it was undoubtedly the best time of my life. I had many friends, and the days in class were fun and enjoyable. I remember that the first day of high school I entered with a lot of fear of not making friends since I didn't know anyone, but after the first playground I had already made 3 friends, one of whom today is my best friend. A not so good stage in high school was repeating the course, since I had a bad time both socially with my new classmates and on a personal level.

The Digital Connection

Anatomy of the Eye

The retina of the eye, lining the posterior two-thirds of the eyeball, is located within the inner tunic.

The jelly-like substance located between the lens and retina is the vitreous body.

True or false: Accommodation refers to the change in lens thickness in order to provide fine focus of an image. The answer is true.

Functions of the Vitreous Body:

• Maintains shape of eyeball
• Refracts rays of light
• Keeps retina smoothly pressed against inner surface of eye chamber

Hemidecussation occurs within the visual projection pathway at the optic chiasm.
