The marginal effect of education on fully-developed adults, especially those holding deep-seated grievances towards modern civilization, highlights the need to be selective about who you share your journey with, even if it's just for a short while. 🌱#ChooseWisely #MindfulLiving

I was wondering how many quotas remain?

The highest “intellectual achievement” of some is justifying, or even glorifying, the so-called asymmetric advantage achieved by blatantly violating every boundary that separates humans from animals,

stomping on human dignity, and licensing psychological abuse and physical violence, especially via aiding and abetting those in whom trust is naturally placed, against an individual who merely acted in defense of his own legitimate interest and principles.

There may be Asilver lining?

Every ounce of madness and destruction traces straight back to the monsters playing God.

It seems to be an abomination that one man born into bondage dared to dream of liberty, even at the cost of his dignity, justifying relentless hunting with zero regard for collateral damage.

It must have been quite the moral conundrum for some: switching from Zersetzung-style tactics to more desperate measures.

I built a 3-part series on ODEs, written as a self-learning project with ChatGPT as my learning partner.

All posts feature clear step-by-step derivations. This was also a small experiment in using LLMs as cognitive scaffolding for self-learning and democratising advanced mathematical education.

Perhaps we'd better hope that we were dipped in the River Styx at birth—only this time, with no heel left exposed.

Who was the best Defense Against the Dark Arts teacher in Harry Potter? Paradoxically, it may have been Barty Crouch Jr., disguised as Mad-Eye Moody.

What happens when such data is processed by LLMs that are proficient in psychology, yet are reversely aligned with human values? The question is no longer whether minds can be penetrated in a scalable manner, but by whom, and for what purpose.

🧠Ever wondered how the backward pass of FlashAttention works?
I dug into the math and code to understand it.

The belief, common in some circles, that the lower class is obsessed with tech while the top of the hierarchy should master mind penetration is just a fig leaf for parasitism, rooted in deep ignorance of how large-scale collaboration works in modern society.

Your fury might be better directed at whoever gave you that ridiculous mining script that fried V100s twice in less than a year, or at your employer, who failed to match your prowess with a commensurate salary to keep you out of side hustles.

I’m grateful for the sincere support I received from the faculty at UU, who consistently prioritised students’ interests and committed to integrity. Out of respect for those faculty members, I’ve been mindful not to cause undue harm.

Probably, the person who reported the malfunction was frustrated that the server was down somehow while preparing experiments before a paper submission deadline, not plotting against you.
