windows_hater_7on Math Academy, part 1: My eigenvector embarassment

I asked myself the same thing. The article said “learn” Linear Algebra, not “review” Linear Algebra. Do some undergrad math programs not teach Linear Algebra?

windows_hater_7on In a showdown of psychotherapists vs. ChatGPT, the latter wins, new study finds

> “participants in most cases preferred ChatGPT’s take on the matter at hand.”

That doesn’t come as a surprise to me. I’ve tried several modalities and intensities of therapy from CBT and DBT to Psychoanalysis, and I find ChatGPT more beneficial. A crucial benefit of ChatGPT is its 24/7 availability. By reducing the barrier to availability, it becomes much easier to get help as unhealthy beliefs and behaviors emerge. Perhaps, LLMs could augment clinician understanding of the environmental factors that trigger patient symptoms.

windows_hater_7on Do AI detectors work? Students face false cheating accusations

A high school I worked at had a similar system in place called Evolv. It’s not a metal detector, but it did successfully catch a student with a loaded gun in his backpack.

They often arrive late when security procedures like bag scanning are not in place.

windows_hater_7on Show HN: Peak Brain Plasticity book – maximize brain power

Given that he has no formal qualifications in neuroscience or any related field you shouldn’t trust him. The author of the book posted the thread. Anyone offering to offer “actionable insights to fortify the brain against degenerative diseases and enhance cognitive performance” should have a prefix of “Dr.” with MD or PhD after their name, and peer reviewed experiments as evidence. He is a “certified IT project manager” and is calling his personal anecdotes “experiments.”
