Vertical AI's Bitter Pill: The Rise of Horizontal AI

2025-01-21

This post explores the competition between vertical AI applications (AI optimized for specific domains) and horizontal AI applications (more general-purpose, scalable AI). Using personal experience and Hamilton Helmer's Seven Powers framework, the author argues that as model performance improves, vertical AI applications struggle to maintain a competitive edge. Except for a rare few possessing exclusive and essential resources, most vertical AI applications will eventually be overtaken by superior horizontal AI. Horizontal AI, akin to a remote coworker, is easily integrated, cheaper, and continuously improves performance through model advancements. The author uses their AcademicGPT project as a case study, showing how a vertical AI application was surpassed by more general horizontal AI models.

Akira Ransomware Cracked: GPU Brute-Force Method Discovered

Security researcher Tinyhack has discovered a GPU-based brute-force method to decrypt the Akira ransomware. Akira, known for its exorbitant ransom demands (reaching tens of millions of dollars), targets high-profile victims. Using an RTX 4090, Tinyhack cracked encrypted files in 7 days; 16 GPUs reduced this to just over 10 hours. The method exploits four nanosecond timestamps used as seeds in Akira's encryption, brute-forcing to find the precise timestamps and generate decryption keys. Success requires untouched files and local disk storage (NFS complicates decryption). While a significant cybersecurity win, Akira's developers will likely patch this vulnerability quickly.

The 2022 Tax Law Change That's Causing Tech Layoffs

A seemingly innocuous change in the 2017 Tax Cuts and Jobs Act, effective in 2022, mandated the amortization of R&D expenses over five years instead of immediate deduction. This significantly impacted tech companies' cash flow, forcing many to lay off employees to cover increased tax liabilities. Smaller firms were particularly hard hit, while larger companies shifted R&D to countries with more favorable tax systems, resulting in US job losses. This wasn't just a tech problem; it affected a large swathe of the US economy, prompting calls for a policy reversal.

The Royal Navy's Century-Long Battle Against Lightning Rods

In the mid-18th century, Benjamin Franklin elucidated the nature of lightning and advocated for lightning rods. Yet, a century later, the British Navy remained unconvinced. Dr. William Snow Harris invented a shipborne lightning rod system and demonstrated its principles through an ingenious booklet with interactive, gold-leafed illustrations. Despite his decades-long efforts, backed by data, experiments, and key lightning incidents, the Navy resisted. Only after political maneuvering was Harris finally successful in 1842, getting his lightning rods installed on all Royal Navy vessels. His victory was short-lived, however; the advent of ironclad ships rendered them obsolete. This story highlights the enduring struggle between scientific discovery and political decision-making.

Building a Robust Evaluation Framework for RAG Systems

Qodo built a Retrieval Augmented Generation (RAG)-based AI coding assistant and developed a robust evaluation framework to ensure accuracy and comprehensiveness. Challenges included verifying the correctness of RAG outputs derived from large, private datasets. The framework evaluates the final retrieved documents and the final generated output, focusing on 'answer correctness' and 'retrieval accuracy'. To address the challenges of natural language outputs, they employed an 'LLM-as-judge' approach and built a ground truth dataset with real questions, answers, and context. For efficiency, they leveraged LLMs to assist in dataset construction and used LLMs and RAGAS to evaluate answer correctness. Ultimately, they built their own LLM judge and combined it with RAGAS for improved reliability, integrating it into their workflow with regression testing, dramatically reducing the effort to verify code changes' impact on quality.

Near-Catastrophic OpenZFS Bug Highlights the Power of Rust's Type System

A subtle yet devastating bug in OpenZFS's core disk allocation function was recently discovered. The bug, a simple type error resulting in the wrong size being returned, could silently overwrite data. It took nearly two days to track down. While the bug wasn't present in any released version, it spurred reflection on the limitations of static analysis in C and the advantages of Rust's type system. Rust's ability to define custom types (like `PhysicalSize` and `AllocatedSize`) would have prevented this. The author argues that relying solely on programmer perfection is flawed; leveraging tools and language features to improve code quality and mitigate hard-to-detect, high-impact bugs is key.
