4 train

Lexington Av express train that goes from Crown Heights Utica Av in Brooklyn to Woodlawn in the Bronx. Has a total of 35 stops and when you wait for the train at Utica Av, it does not open its doors right away, you have to wait about 5 minutes for the doors to open while suffocating underground in the heat. The 5 train is a little bit faster than the 4 in my opinion.

Type 4 Fun

Type 4 Fun is fun for no one in the situation, and an experience that is wished to be forgotten.
Person 1: "Remember that camping trip where everyone got bitten by the ants under the tent?"

Person 2: "I'd forgotten it until now, that was Type 4 Fun."

Watching your favorite streamers debate an extremely boring topic is 'Type 4 Fun.'

FR-4

FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

"FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The designation FR-4 was created by NEMA in 1968.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.

Grade designations for glass epoxy laminates are: G-10, G-11, FR-4, FR-5 and FR-6. Of these, FR-4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics. Hence, FR-4 has sincewhen? replaced G-10 in most applications.
Fenhar FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable traitcitation needed will still use G-10 non flame resistant.

4 is an open door

In the Australian university system, 4 is a pass, and 7 is a full mark, so at the end of the semester, you will see a bunch of hustlers who did not watch a single lecture sitting outside during the exam block singing "4 is an open door," which is the urban version of the frozen song "Love is an open door, "where Anna met the evil prince Hans, the man she wanted to settle for life.
Hey man, how did your exam go?
It's been crazy.
Crazy?
Yeah, I winged every single thing.

All my life has been a series of doors in my face.
And then, suddenly, this one smashed right into my face
I was thinking the same thing, 'cause like
I've been studying my whole life to get into a university like this
And maybe I've been partying too hard, but I love the thrill of jumping on the edge of a 49 and a 50.

But with you (but with you...)
4 is an open door
with you
with you

Life could be so much more!

4 Factors

According to AI

1. Purpose and Character of the Use: This factor considers whether the use is transformative, meaning it adds new meaning, purpose, or message to the original work. Uses like criticism, commentary, news reporting, teaching, scholarship, or research are generally favored. Commercial uses are viewed less favorably, but not automatically ruled out as fair use, according to Emerson College Library.

2. Nature of the Copyrighted Work: The nature of the copyrighted work plays a role. Factual or public documents are more likely to be considered fair use than creative works. For example, using factual information from a book in a news article might be fair use, but using a large portion of a creative novel in a new work might be less likely to be fair use.

3. Amount and Substantiality of the Portion Used: This factor looks at how much of the original work is used. Generally, the less used, the better. Courts also consider whether the portion used is the "heart" of the original work. Using only a small portion or a non-essential part is more likely to be fair use, according to Emory Libraries.

4. Effect of the Use on the Market: This factor considers whether the use harms the market for the original work or any potential markets for it. If the use directly competes with the original work or could potentially harm its future sales, it's less likely to be fair use, according to the University of Washington.
Hym "1. I definitely have an interpretation that adds new meaning (at least as it pertains to the parts of the bible and more broadly Jordan Peterson's work) and I definitely added a new message. Used like criticism. ✔️

2. I use factual work mostly or work put forth as factual. I'll plug some creative work or even use quotes. And I DEFINITELY USE NEWS ARTICLES! That's for sure! ✔️

3. Not much actually. Usually never more than a proposition. But you can't really say Jordan is using Nietzsches work in the "heart." Therefore, my work is in the same "heart" as Jordan's in that regard (all be it in the opposite direction) And you can't say the same about you using MY work because the "heart" of MY work is A. shedding light on the targeted harassment that mirrors the delusions of reference commonly associated with schizophrenia I've been subjected to since I was 19 (or sooner) and remediation of this harassment WHICH NONE OF THE MOVIES OR SHOWS ADDRESS AND HAS ONLY GOTTEN WORSE. B. (And I'm quoting myself here) "Demonstrating my abject superiority to all men, women, and children." Which none of this does. The Anime gets a pass but the rest of you don't. C. Getting myself credit AND MONEY for creating AI. I was explicit. ✔️ for me and not for you.
