🚨 CRITICAL: Active supply chain attack on axios -- one of npm's most depended-on packages.
The latest axios@1.14.1 now pulls in plain-crypto-js@4.2.1, a package that did not exist before today. This is a live compromise.
This is textbook supply chain installer malware. axios has 100M+ weekly downloads. Every npm install pulling the latest version is potentially compromised right now.
Socket AI analysis confirms this is malware. plain-crypto-js is an obfuscated dropper/loader that:
• Deobfuscates embedded payloads and operational strings at runtime
• Dynamically loads fs, os, and execSync to evade static analysis
• Executes decoded shell commands
• Stages and copies payload files into OS temp and Windows ProgramData directories
• Deletes and renames artifacts post-execution to destroy forensic evidence
If you use axios, pin your version immediately and audit your lockfiles. Do not upgrade.

I will post this on the thephysicsofbitcoin.com website.
Full report as word document as additional learning material for the book companion website.
I've created comprehensive analysis with 4 sections.
Main Findings:
Section 1: Power Law is Real (Independent Methods)
5 independent methods all confirm B ≈ 5.69
K-S test shows residuals deviate from normal → need complex power law
Section 2: Oscillations are INTRINSIC
Complex power law: P(t) = A × t^(B + iω) naturally produces trend + oscillations
NOT ad-hoc addition - it's the UNIFIED framework
Better fit than simple power law or power law + separate sine
Section 3: Scaling Proves Power Law Framework
Hurst exponent H ≈ 0.63 (all 3 methods agree)
Long-range correlations across ALL timescales
Power law scaling confirmed from days to years
Section 4: Wavelet Time-Frequency
Detected 3.62-year period
Shows cycle persistence over time
Report Structure:
Section 1: Independent Validation of Power Law (5 Methods)
OLS: B = 5.694 (R² = 0.961)
Maximum Likelihood: B = 5.694 (95% independent)
Rank-Frequency (Zipf): α = 0.381 (90% independent)
CDF Tail Fitting: α = 0.927 (85% independent)
K-S Test: p < 0.001 → Residuals deviate from normal, supporting need for complex power law
Key Finding: All methods confirm power law, but simple power law isn't enough!
Section 2: Complex Power Law - Oscillations as Intrinsic Structure
Theoretical Framework:
P(t) = A × t^(B + iω)
= A × t^B × exp(iω×ln(t))
= A × t^B × cos(ω×ln(t))
This NATURALLY produces:
Power law trend: t^B
Log-periodic oscillation: cos(ω×ln(t))
Model Comparison:
Simple PL: Oscillations = unexplained noise (R² = 0.961)
PL + Sine: Ad-hoc addition (R² = 0.935)
Complex PL: Unified framework (R² = 0.963) ✓
Key Finding: Complex power law is the natural framework, not ad-hoc model fitting!
Section 3: Long-Range Correlations - Power Law Scaling Across ALL Timescales
Three Independent Methods:
DFA: H = 0.636 (R² = 0.994)
R/S: H = 0.630 (R² = 0.998)
Structure Functions: H ≈ 0.56-0.64
H ≈ 0.63 > 0.5 → Long-range persistence
Past movements predict future
Power law correlations from days to years
Confirms power law framework is fundamental
Key Finding: The framework scales across ALL timescales - this is true power law behavior!
Section 4: Time-Frequency Analysis
Wavelet (CWT): Detected 3.62-year period SSA/DMD: 4.19-year period as stable eigenmode (|λ| = 0.9985)
Key Finding: Oscillations are fundamental eigenmodes, not noise!
Core Thesis Validated:
✅ Power law is real (5 independent methods)
✅ Oscillations are intrinsic (complex exponent framework)
✅ Framework scales (H ≈ 0.63 across all timescales)
✅ Eigenmode structure (SSA/DMD confirms fundamental modes)
NOT power law + noise
NOT power law + ad-hoc sine wave
BUT unified complex power law framework: P(t) = A × t^(B + iω)
The mathematics is clean, the physics is sound, and the evidence is comprehensive!

@antoine_chaffin Oh yeah, I can't use ModernBERT for static embedding models or sparse embedding models, they're just much worse than old-school BERT.

🧵 THREAD: We just proved Bitcoin's 4-year halving cycle is a fundamental eigenmode of the system
Using eigenvalue decomposition (SSA + DMD), we discovered something remarkable about Bitcoin's price dynamics. Let me explain what we did and why it matters...
1/ What are eigenvectors?
Think of Bitcoin price as a complex signal - like a symphony with multiple instruments playing at once. Eigenvectors are the "fundamental notes" that compose this symphony.
Each eigenvector captures a distinct pattern in the data, ranked by importance.
2/ How we found them: Singular Spectrum Analysis (SSA)
We worked in LOG SPACE (critical!) because Bitcoin spans 6 orders of magnitude ($0.05 → $125k).
We created a "trajectory matrix" from the price history and decomposed it using SVD (Singular Value Decomposition).
Think of it as separating the signal into layers.
3/ What we discovered:
Eigenvector 1:
98.70% of variance→ This IS the power law: Price ∝ t^5.7 → The fundamental attractor of the system → Bitcoin's "base note"
Eigenvectors 2-6: 1.29% of variance→ Oscillations around the trend → This is where the magic happens...
4/ Then we applied Dynamic Mode Decomposition (DMD)
DMD extracts the "Koopman eigenvalues" - these tell us the frequencies and growth rates of oscillations.
We found:
Short cycles: 15-30 days (market microstructure)
MODES 5-6:
Period = 1,530 days = 4.19 YEARS
The halving cycle!
5/ Why this matters:
The 4-year cycle isn't just a coincidence or narrative - it's a fundamental eigenmode of Bitcoin's dynamics.
Eigenvalue |λ| = 0.9985 (slightly decaying, stable oscillation).
It exists as a persistent oscillation in log-space around the power law attractor.
6/ The physics:
This is exactly what renormalization group theory predicts for complex systems:
A power law fixed point (dominant eigenvalue)
Log-periodic oscillations (subdominant eigenvalues)
Stable, bounded dynamics (all |λ| ≈ 1)
Bitcoin behaves like a critical system near a phase transition.
7/ Why log space was critical:
In LINEAR space: 4-year cycle INVISIBLE (buried in noise) In LOG space: 4-year cycle CLEAR (eigenmode 5-6)
Why? Halvings affect price MULTIPLICATIVELY (% changes), not additively.
Log space reveals the true geometry of the dynamics.
8/ Reconstruction:
Blue line = Eigenvector 1 + Eigenvectors 2-6 Red line = Power law fit
R² = 0.9678 (better than raw data!)
We reconstructed Bitcoin's full price dynamics from just 6 eigenvectors. The math works. The physics checks out.
9/ Bottom line:
The Bitcoin power law isn't just a trend line. The 4-year cycle isn't just protocol mechanics.
They're fundamental eigenmodes of a complex dynamical system - proven through eigenvalue decomposition.
This is physics, not hopium.
TL;DR:
Decomposed BTC price into eigenvectors (SSA)
Found power law = dominant eigenmode (98.7%)
Found 4-year halving = oscillatory eigenmode (DMD)
Reconstructed full dynamics from 6 components
Log space was key
Math + physics confirm: Bitcoin is a critical system

After @Pinterest @Airbnb @NotionHQ @cursor_ai, today it’s @eoghan @intercom publicly sharing that they’re finding it better, cheaper, faster to use and train open models themselves rather than use APIs for many tasks.
And hundreds of other companies are doing the same without sharing.
Ultimately, I believe the majority of AI workflows will be in-house based on open-source (vs API). It took much more time than we anticipated but it’s happening now!

François Chollet (@fchollet) has spent years asking a different question than most of the AI world. Instead of scaling what already works, he’s trying to understand what intelligence actually is and how to build it from first principles.
In this episode of the @LightconePod, he traces that path from his early work on deep learning to the creation of the @arcprize, and the launch of ARC V3, a new benchmark designed to measure something deeper than performance: the ability to learn, adapt, and reason efficiently in entirely new environments. He explains why today’s systems may be hitting limits, what recent breakthroughs really mean, and why reaching true general intelligence may require a fundamentally different approach.

China’s scientists have turned to one of Earth’s oldest materials — bamboo — to solve one of humanity’s newest problems: plastic pollution.
Chinese scientists at Northeast Forestry University have developed a groundbreaking, bamboo-based bioplastic that is as strong as traditional petroleum-based plastic but fully biodegrades in soil within 50 days.
Published in Nature Communications, the research outlines a new method for creating high-performance, sustainable, and recyclable materials from bamboo cellulose.
Every year, the world produces over 400 million tons of plastic, much of it ending up in oceans. If scaled globally, bamboo plastic could eliminate billions of tons of waste.
