WikiLeaks revealed the CIA distributed a fake VLC build with a DLL that exfiltrated documents during movie playback; Chinese hackers also used a signed VLC DLL; VLC was temporarily banned in India. [1] — Jean-Baptiste Kempf "At least two intelligence agencies approached VideoLAN requesting backdoors in VLC. The answer was an unambiguous no. VLC compiles on air-g…" 3:55:50
Real-time robot control demands video latency measured in milliseconds, not seconds. Kyber encodes a single video frame in 4 milliseconds, uses QUIC-based multi-stream transport with forward error correction, and handles clock drift across multi-camera robot setups to guarantee coherent training data for AI models. Current achievement: 7ms glass-to-glass. Target: 4ms (240 Hz equivalent).
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
Humans are estimated to have 5,000–7,000 thoughts per day, yet can recall essentially none of them afterward, highlighting why in-the-moment emotional tracking matters.
A large Harvard study found that a wandering mind is an unhappy mind — people report greater happiness when their attention is tethered to the present, even if the task is unpleasant.
A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.
Rejection sensitivity can be observed as early as age 2 or 3, suggesting it has strong developmental and likely genetic roots.
A Yale study found that non-judgmental observation of emotions — without rushing to resolve them — reduces activation in the brain, making it a powerful regulation tool.
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
