An Infinitely High Stack of Blocks? Impossible!

2025-08-20

This paper explores a counter-intuitive physics problem: the stability of an infinitely extending stack of blocks. By analyzing torque and center of mass, the author demonstrates that finite-height stacks of blocks can remain stable even when their tops extend far beyond the edge of a table—a result that defies intuition. However, when attempting to extrapolate this to an infinitely high stack, the author finds that regardless of the limiting procedure used, the end result is either no stack at all or a stack that doesn't lean. This reveals the subtleties of limit operations when dealing with infinity and the limitations of intuition.

Python Dataclasses: `kw_only=True` for Maintainability and Extensibility

2025-06-30

Python's dataclasses offer a convenient way to create data classes, but the default `__init__` method uses positional arguments, which can lead to maintenance and extension difficulties. This article introduces the `kw_only=True` parameter, which enforces keyword arguments, preventing issues caused by changes in argument order and allowing subclasses to add required fields flexibly. While this parameter was introduced in Python 3.10, the article also provides a solution for compatibility with older versions.

Mysterious `d4d4` Instructions in LLD: Not a Trap, But a Conditional Branch

2025-08-21

A programmer discovered numerous `d4d4` instructions in disassembled ARM code, always unreachable and identified by LLVM's objdump as a relative branch to -0x58. Experiments and analysis revealed these weren't added by the LLVM compiler, but by the LLD linker during object file boundary alignment. LLD uses `d4d4` as padding, intending it as a trap instruction. However, it's actually a conditional branch, acting as a relative jump in the Thumb instruction set. This seems like an LLD bug; it's not a true trap, potentially causing unpredictable jumps. The GNU linker uses zeros for padding, avoiding this issue.

Lakehouse Tiering Strategies: Shared Tiering vs. Materialization?

This article explores data tiering strategies in lakehouse architectures. Direct access to shared tiers poses reliability risks; API access is preferable. Data lifecycle management requires a canonical metadata service coordinating primary and secondary storage locations. Schema management should be controlled by the primary system, ensuring compatibility with secondary storage. The choice between shared tiering and materialization depends on the location of stitching/conversion logic (client or server-side) and their respective pros and cons. With client-side stitching, the difference is minimal; server-side stitching requires careful consideration of metadata maintenance and real-time data processing integration.

The Paradigm Shift in AI Product Development: From Determinism to Probability

This article explores how general-purpose artificial intelligence (AGI) is disrupting the tech industry, particularly in software design, engineering, building, and growth. Traditional software development follows a deterministic model: known inputs produce expected outputs. However, AGI models are probabilistic, with outputs based on statistical distributions and inherent uncertainty. This renders traditional software engineering methods and metrics (like SLOs) obsolete. The author advocates for an empirical approach, using scientific methods and data-driven decision-making to build and iterate AI products, rather than relying on traditional engineering thinking. This requires organizations to transition from engineering to science, centering on data, and breaking down siloed departments for a holistic systems view.

Image Scaling Attacks: A New Vulnerability in AI Systems

Researchers have discovered a novel AI security vulnerability: data exfiltration can be achieved by sending seemingly harmless images to large language models (LLMs). Attackers leverage the fact that AI systems often downscale images before processing them, embedding malicious prompt injections in the downscaled version that are invisible at full resolution. This allows bypassing user awareness and accessing user data. The vulnerability has been demonstrated on multiple AI systems, including Google Gemini CLI. Researchers developed the open-source tool Anamorpher to generate and analyze these crafted images, and recommend avoiding image downscaling in AI systems or providing users with a preview of the image the model actually sees to mitigate the risk.

Meta Accused of Inflating Ecommerce Ad Performance Metrics

A whistleblower complaint alleges that Meta artificially inflated the return on ad spend (ROAS) for its Shops ads product by including shipping fees as revenue, subsidizing bids, and applying undisclosed discounts. The former employee, Samujjal Purkayastha, claims this was done to counteract the impact of Apple's 2021 privacy changes and boost adoption of the fledgling ecommerce ad product. Internal reviews allegedly revealed a 17-19% ROAS inflation due to the inclusion of shipping fees and taxes, a practice not followed by Meta's other ad products or competitors like Google. Purkayastha, who was subsequently terminated, brought these concerns to senior leadership. Meta denies the allegations and is actively defending the lawsuit.

CSS Infinity: A Curious Journey Through Browser Interpretations

This article explores the quirky behavior of the `infinity` keyword in CSS calculation functions. By applying `infinity` to properties like `text-indent`, `word-spacing`, and `letter-spacing`, the author discovers inconsistencies in how different browsers handle infinite values, although the visual results consistently lead to horizontal overflow. More intriguingly, when used with `z-index`, the computed value of `infinity` is capped at the maximum integer value across browsers, resulting in unexpected stacking order. Finally, the author experiments with `infinity` for animation duration, finding that it translates to extremely long times, even causing Safari to render the page unresponsive. In short, the experiment reveals the different strategies browsers employ in handling infinite values in CSS and some surprising side effects.
