Releasing a new "Agentic Reviewer" for research papers. I started coding this as a weekend project, and @jyx_su made it much better.

I was inspired by a student who had a paper rejected 6 times over 3 years. Their feedback loop -- waiting ~6 months for feedback each time -- was painfully slow. We wanted to see if an agentic workflow can help researchers iterate faster.

When we trained the system on ICLR 2025 reviews and measured Spearman correlation (higher is better) on the test set:
- Correlation between two human reviewers: 0.41
- Correlation between AI and a human reviewer: 0.42

This suggests agentic reviewing is approaching human-level performance.

The agent grounds its feedback by searching arXiv, so it works best in fields like AI where research is freely published there. It’s an experimental tool, but I hope it helps you with your research.

🇱🇰 3 Months, No Policy — E-Commerce Still in Limbo

⭕ It has been over 3 months since the government supposedly began working on a new framework for taxing and releasing e-commerce goods.

⭕ As usual with the Department of Trade and Investment policies & Dept of Customs, nothing has materialized.

⭕ Meanwhile, 🇨🇳 AliExpress continues to impose arbitrary taxes on goods electronic parts, circuit components, and educational items that cannot be sourced elsewhere.

⭕ The worst part is that there is no cross-check mechanism between what customers pay as “taxes” and what intermediaries declare to customs — meaning much of the changed fees as "taxes" never reaches government coffers.

🚆 Passport/NIC Verification System Now Operational for Sri Lanka Train Bookings 🇱🇰

Sri Lanka Railways has launched a mandatory identification verification system for train ticket reservations.

⭕ All passengers now must provide NIC number (Sri Lankan citizens) or passport number (foreign nationals) when booking seats online or at counters, with original documents required for verification during boarding and ticket checks.

⭕ Policy applies exclusively to reserved seats on intercity, long-distance, and premium train services across all routes, while unreserved ticket purchases remain unaffected by this requirement.

⭕ System is designed to eliminate illegal resale activities, and stop black market sales that were inflating prices, particularly on popular tourist routes like Kandy-Ella.

The single most destructive falsehood taught in school wasn’t a fact, it was a frame:

“The system is neutral.”

We were taught:
•History is objective
•The economy is fair
•Science is apolitical
•Authority is earned
•Success is linear
•Money follows merit
•The future will reward obedience

All of it designed to manufacture compliance not understanding.

The truth is:
•History is written by power.
•The economy is shaped by leverage, not labor.
•Science is real, but funding decides the questions.
•Authority is often inherited or engineered.
•Success follows strategic asymmetry.
•Money follows network, not virtue.
•The system rewards signal, not submission.

We weren’t taught how the world works.
We were taught how to function inside the world they already built.

That’s why so many wake up at 30, 40, or 50 and feel betrayed.
The curriculum was never designed to liberate you.
It was designed to format you.

The deepest falsehood wasn’t any one fact.
It was the illusion that the system was built for truth.

Wow, actual grown men are still doing the "I asked the LLM about itself and it said" thing.

In 2025.

Folks, LLMs don't know anything about how they themselves are built or deployed, unless they've been explicitly programmed with that information (which they almost never are).

Both for-profit education & for-profit healthcare are both highly efficient & highly profitable for shareholders.

The only problem is that students & patients are not the shareholders.
