FLAME: A Lightweight Language Model for Spreadsheet Formulas

2025-01-22

Large language models are expensive to train and deploy for assisting with Excel formula authoring. This paper introduces FLAME, a transformer-based model trained exclusively on Excel formulas. With only 60 million parameters and a fraction of the training data used by larger models, FLAME achieves competitive or even superior performance on formula repair, completion, and retrieval tasks compared to models like Codex and CodeT5. This is attributed to its novel pre-training objectives and Excel-specific tokenizer.

Critical AMD Zen CPU Microcode Vulnerability Allows Malicious Code Injection

Google's security team discovered a critical vulnerability in AMD Zen CPUs (Zen 1-4). An attacker with local administrator privileges can bypass insecure signature verification to load malicious microcode patches, compromising the confidentiality and integrity of confidential computing workloads protected by AMD SEV-SNP and potentially the Dynamic Root of Trust for Measurement (DRTM). AMD released a fix on December 17th, urging users to verify TCB values for SNP. Further details and tools will be released on March 5th by Google to allow time for remediation.

Chinese Scientists Achieve Breakthrough in High-Temperature Superconductivity

Scientists at Southern University of Science and Technology (Sustech) in China have observed high-temperature superconductivity in a thin film of nickel oxide crystals, achieving resistance-free electricity conduction at a relatively high temperature of 45 Kelvin (-228°C) without high pressure. Published in Nature, this research offers new hope for understanding the mechanism of high-temperature superconductivity and designing room-temperature superconductors. The discovery promises to make technologies like magnetic resonance imaging significantly cheaper and more efficient. While the critical temperature of nickel-based superconductors still needs improvement compared to copper-based ones, the team is actively exploring ways to optimize the material's growth and composition to further raise its critical temperature.

Australia's Treasury Copilot Trial: ROI Positive, But Employee Confidence Lags

A 14-week trial of Microsoft 365 Copilot by Australia's Department of the Treasury showed a positive return on investment (ROI), but employee confidence in its workplace effectiveness fell short. The trial revealed Copilot's actual applicability was lower than anticipated, with most participants using it less than three times a week. While Copilot excelled at basic administrative tasks like summarizing information and generating meeting minutes, it struggled with more complex tasks. The Treasury concluded that more careful staff selection, comprehensive training, and ongoing monitoring of AI's impact are crucial. The findings also hinted that AI-as-a-service might not be suitable for organizations handling sensitive data like the Treasury, suggesting on-premises AI infrastructure may be preferable.

Argentine President's Memecoin Promotion Ends in $107M Insider Dump

Argentine President Javier Milei's tweet promoting a memecoin called Libra, touted as a project to boost the Argentine economy, led to a spectacular crash. The token initially soared, but within hours, insiders holding roughly 82% of the tokens dumped their holdings, cashing out approximately $107 million and causing a 95% price drop. Milei subsequently deleted his tweet and claimed ignorance of the project's details. The incident highlights the risks of memecoins and the potential for manipulation in highly concentrated markets.

The Myth of High IQ: Just How Smart Was Einstein?

2025-02-23

The Myth of High IQ: Just How Smart Was Einstein?

This article challenges the common fantasy of assigning high IQ scores to historical figures, particularly Einstein's supposed IQ of 160. By analyzing Einstein's academic record and the limitations of modern IQ tests, the author argues that extremely high IQ scores (e.g., above 160) are unreliable. High-range IQ tests suffer from significant measurement error, and the correlation between such scores and real-world achievements is weak. The author critiques flawed studies, such as Anne Roe's estimations of Nobel laureates' IQs. The conclusion is that the obsession with stratospheric IQ scores is unfounded; true genius lies in creativity, deep thinking, and drive, not a single number.

First Fatal Crash Involving a Driverless Car

A multi-vehicle crash in San Francisco marks the first fatal collision in the U.S. involving a fully autonomous vehicle with no one behind the wheel. While a Waymo self-driving car was involved, it wasn't at fault; a speeding vehicle hit a line of stopped cars, resulting in one human fatality and the death of a dog. Despite Waymo's claim of superior safety records compared to human drivers, based on millions of miles driven, the incident raises serious questions about the safety of autonomous vehicles and will likely trigger further scrutiny of the technology.

The Gordian Knot of Online Schema Changes and Foreign Keys in MySQL

This post dissects the inherent challenges of performing online schema changes in MySQL, particularly when dealing with tables linked by foreign key relationships. The author analyzes the limitations of existing tools like pt-online-schema-change and gh-ost, highlighting the complexities and risks involved in altering parent tables. Altering a parent table necessitates concurrent alterations of all child tables, creating a fragile process with minimal tolerance for errors. A single failure can lead to data inconsistencies or outages. The author concludes that online schema changes involving foreign key constraints on large tables are practically infeasible.

Microsoft's Breakthrough: The World's First Topological Qubit

Microsoft announced a major breakthrough in quantum computing, unveiling Majorana 1, the world's first Quantum Processing Unit (QPU) powered by a topological core. Built using a novel topoconductor material, it's designed to scale to a million qubits on a single chip. This breakthrough leverages Majorana Zero Modes (MZMs) as qubit building blocks, employing measurement-based computation instead of traditional rotation, significantly simplifying quantum error correction. Partnering with DARPA, Microsoft aims to build a fault-tolerant prototype based on topological qubits within years, not decades, paving the way for a practical quantum computer capable of tackling real-world problems.

Clean: An Embedded DSL and Formal Verification Framework for ZK Circuits in Lean4

2025-03-27

Researchers have developed Clean, an embedded domain-specific language (DSL) and formal verification framework in Lean4 for building zero-knowledge (ZK) circuits. ZK circuits are prone to bugs, and Clean aims to improve correctness by allowing users to define circuits in Lean4, specify their desired properties, and formally prove them. This project is part of the zkEVM Formal Verification Project, aiming to provide infrastructure and tooling for formal verification of zkEVMs. Clean supports four basic operations for defining circuits: witness, assert, lookup, and subcircuit, and offers a monadic interface for enhanced usability. At its core is the FormalCircuit structure, which tightly packages—in a dependently-typed way—the circuit definition, assumptions, specification, soundness, and completeness proofs. Large circuits can be formally verified by recursively replacing subcircuit constraints with their (formally verified) specifications. The framework has successfully verified simple circuits like 8-bit addition, with future plans to add more low-level gadgets, define common hash function circuits, and build a formally verified minimal VM for a subset of RISC-V.

Refactoring Pitfalls: When Not to Refactor

This article explores the pitfalls of code refactoring, highlighting that not all code needs refactoring. The author presents several scenarios where refactoring is inappropriate, such as attempting to fix bugs or adapt to third-party changes through refactoring; introducing unnecessary abstraction leading to code complexity; tackling multiple code smells simultaneously; refactoring untested code; and refactoring unchanging code. The article emphasizes that refactoring should be incremental, behavior-preserving, and involve small, reversible changes with test coverage. It advocates for pausing refactoring when understanding is lacking or new requirements emerge. Refactoring frequently changing and complex code yields the best results.
