Flipper Zero Firmware Bypasses Car Security: Single Button Press Unlock

2025-08-08

YouTube channel Talking Sasquach demonstrated a custom Flipper Zero firmware that breaks the rolling code security of many modern vehicles. The attack requires only a single button-press recording from the key fob to replicate all functions, including unlocking doors and trunks, rendering the original key fob unusable. Affected brands include Chrysler, Dodge, Fiat, Ford, Hyundai, Jeep, Kia, Mitsubishi, and Subaru. Currently, there's no easy fix, potentially requiring mass vehicle recalls. The attack's mechanism might involve reverse-engineering the rolling code sequence or a 'RollBack' attack that resets synchronization by replaying captured codes in a specific order.

2025-05-31

Artyom Bologov shares his unusual journey of building a static website using the ancient text editor ed(1). He's tried various methods, from Lisp to the C preprocessor, finally settling on ed(1) as his static site generator. While ed(1) has limitations, lacking features like file inclusion, its flexibility allows for custom syntax and processing of older preprocessor formats. He uses ed(1) scripts for preprocessing and format conversion, supporting multiple output formats (txt, gmi, 7, tex, etc.). While not a best practice, the article showcases the unexpected potential of ed(1) and the author's unique approach to text processing.

Google's Browser Monopoly: A Looming Internet Crisis

2025-05-01

Google funds over 80% of the development budgets for the four major web browsers: Chrome, Edge, Firefox, and Safari. The US Department of Justice is moving to force Google to cut off funding for its competitors and divest from Chrome. This would cripple the development of all major browsers, severely impacting the internet ecosystem. Google's search engine deals with Mozilla and Apple provide massive payments, accounting for 83% of Mozilla's revenue and a significant portion of Apple's R&D budget. Edge is essentially a white-label version of Google's Chromium open-source project, with Google contributing the vast majority of its code. While the DOJ's action aims to combat Google's anti-competitive practices, the potential consequence is the destabilization of the browser market and the internet's foundational infrastructure.

Lost Nicknames and the Origins of Surnames

Many English surnames derive from patronyms, often nicknames. For example, "Jackson" comes from "Jack" (a nickname for John). This article explores numerous now-obscure nicknames and their resulting surnames, such as "Wat" (a nickname for Walter) yielding "Watts," "Watson," "Watkins"; "Gib" (a nickname for Gilbert) yielding "Gibbs," "Gibson"; and "Hob" (a nickname for Robert) yielding "Hobbs," "Hobson," "Hobkins." The author invites further examples and adds the nickname "Hick" (for Richard) and its derivatives, and speculates on "-mott" possibly indicating an in-law.

Beyond Zig and Rust: A More Human-Friendly Approach to Metaprogramming

2025-05-26

This article explores a novel programming language design that combines the strengths of Rust's Hindley-Milner type system and Zig's compile-time capabilities, while avoiding the complexities of Zig's 'types as values' approach. By introducing the `@` operator for compile-time execution, the `Abstract` type for compile-time abstractions, `TypeInfo` and `Field` types for type introspection, and `Code` and `parse` functions for code manipulation, this design achieves powerful metaprogramming capabilities such as automatic code generation and the implementation of TypeScript-like utility types like `Partial`, all while maintaining code readability and ease of reasoning. This represents a new approach to achieving powerful metaprogramming while preserving type system friendliness, offering fresh perspectives for future language design.

Municipal vs. Airport Fire Trucks: A Tale of Two Trucks

While both municipal and airport fire trucks (ARFF) fight fires, their roles and capabilities differ significantly. Municipal trucks prioritize maneuverability in urban environments, carrying varying water tank sizes (500-1000 gallons) and equipment like hoses, air packs, and small tools. ARFF vehicles, however, are designed for rapid response (within 3 minutes) at airports, boasting larger water tanks (1500-4500 gallons) and a High Reach Extendable Turret (HRET) for tackling aircraft fires. They also carry a wider range of fire suppressants and have stricter acceleration requirements. Differences extend to chassis design and cab configurations, tailored to each environment's unique demands.

Legacy Airlines Crack Down on Carry-On Bags

Flying with legacy carriers like British Airways or Air France used to mean included checked baggage and carry-on. However, to compete with low-cost airlines, many legacy carriers are now eliminating free carry-on allowances and even complimentary meals. Air Canada, for example, will no longer allow standard carry-on bags on North American and Caribbean routes from January 3rd, only permitting small personal items. Other airlines like United and Finnair have adopted similar strategies. This 'basic economy' fare is blurring the lines between legacy and budget airlines, adding extra costs for passengers.

Building Effective AI Agent Evaluation: From E2E Tests to N-1 Evaluations

2025-09-04

This article explores building efficient AI agent evaluation systems. The author stresses that while models constantly improve, evaluation remains crucial. It advocates starting with end-to-end (E2E) evaluations, defining success criteria and outputting simple yes/no results to quickly identify problems, refine prompts, and compare different model performances. Next, "N-1" evaluations, simulating previous user interactions, can directly pinpoint issues, but require maintaining updated "N-1" interactions. Checkpoints within prompts are also suggested to verify LLM adherence to desired conversation patterns. Finally, the author notes that external tools simplify setup, but custom evaluations tailored to the specific use case are still necessary.

Execution Units are Often Pipelined

2024-12-30

This blog post explores the pipelining of execution units in out-of-order microarchitectures. The author initially assumed execution units remain occupied until µop completion, but using the Firestorm microarchitecture (A14 and M1) as an example, demonstrates that two integer execution units can handle multiple multiplications concurrently, each taking three cycles. By comparing dependent and independent instruction sequences, the author reveals that many execution unit/µop combinations are heavily pipelined, allowing a µop to be issued while the unit processes others. This reduces execution time for independent instructions from a predicted 6 cycles to 4. Finally, the author explains why instruction latency and bandwidth tables specify reciprocal throughput – it's equivalent to cycles/instruction.
