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

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.

Global Fertility Crash: A Silent Crisis

Global Fertility Crash: A Silent Crisis

A dramatic decline in global fertility rates is causing widespread concern. From Mexico to South Korea, many countries have fertility rates far below the level needed to sustain their populations. This not only leads to labor shortages and slower economic growth, but can also weaken national strength. While some countries are trying to raise fertility rates through economic incentives and other measures, the effects are limited. Experts recommend shifting the focus from raising fertility rates to increasing societal resilience to adapt to the challenges posed by demographic change. Sub-Saharan Africa is an exception, with its population expected to continue growing.

Chernobyl Radiation Crashed a Soviet Rail System

2025-08-20

In the 1980s, programmer Sergei encountered mysterious crashes on an SM-1800 microcomputer at a Soviet rail station. The system, used for routing trains, would randomly fail at night. Investigation revealed the crashes only occurred when processing livestock from northern Ukraine and western Russia. Suspecting Chernobyl radiation, Sergei confirmed his theory: high radiation levels flipped bits in the SM-1800's memory. The Soviet government mixed contaminated and uncontaminated meat to avoid waste. Upon discovering this, Sergei immediately filed immigration papers. The computer crashes resolved themselves as radiation levels dropped.

Image Scaling Attacks: A New Vulnerability in AI Systems

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.

A 1Hz Clock from Three Candles: Reversing Millennia of Optimization

For millennia, candlemakers have strived for flicker-free candles. However, when three candles are bundled together, they surprisingly begin to oscillate naturally at ~9.9Hz, a frequency primarily determined by gravity and flame diameter. The author ingeniously uses a wire suspended in the flame to sense capacitance changes caused by ionized gases, detecting this frequency and dividing it down to 1Hz. The result? A 1Hz clock built with a simple microcontroller and an LED, powered by the flickering of three candles.

The UK will no longer compel Apple to provide backdoor access to its iCloud encryption, according to US Director of National Intelligence Tulsi Gabbard. This follows a January order demanding access to encrypted data globally. Apple challenged the order, citing the CLOUD Act, a bilateral agreement preventing such data demands between the US and UK. US pressure reportedly led the UK to withdraw its request. It remains unclear if Apple will reinstate its enhanced encryption service in the UK.

MCP Tools with Dependent Types: A Defold Editor Experiment

2025-08-18

This post details an experiment using a Large Language Model (LLM) within the Defold game editor. The author initially attempted to use Claude to directly manipulate Lua code, but faced low accuracy. The proposed solution involved using JSON Schemas to define tool inputs, but this ran into a limitation: the inability to implement dependent types within the Model-Code-Prompt (MCP) framework. This means the structure of tool input depends on runtime information. For example, editing 3D models requires different properties depending on the chosen material. The solution is a two-step process: the LLM selects a resource, the program looks up its data structure and constructs a JSON Schema; then, the LLM uses this schema to generate edits. The author suggests MCP should support dependent types to handle complex data more effectively.

Firefox's CRLite: Faster, More Private Certificate Revocation Checking

Firefox is the first browser to implement fast and comprehensive certificate revocation checking without revealing user browsing activity. Previously, the OCSP protocol leaked user privacy. Firefox's new CRLite mechanism solves this by periodically downloading a compact encoding of revoked certificates, storing and updating it locally. CRLite is a thousand times more bandwidth-efficient than traditional CRLs and significantly improves TLS handshake times. Firefox will disable OCSP in version 142, further enhancing user privacy and performance.

Mastering Attention: Crafting Effective Prompts for LLMs

This article delves into the attention mechanism of Large Language Models (LLMs) and how to leverage it through carefully crafted prompts. It explains that LLMs don't read sequentially like humans, instead weighting relationships between all tokens simultaneously. Prompt structure, therefore, is more impactful than word choice. The article contrasts structured and unstructured prompts, illustrating how a step-by-step approach guides the model's reasoning. It simplifies the attention mechanism: calculating each word's influence on others to generate output. Heuristics for effective prompts are offered: prioritizing key information, using structured formatting, employing personas, and avoiding vagueness. The article concludes by emphasizing the economic benefits of efficient prompting—saving engineer time, improving efficiency, and reducing costs.

Your MCP Doesn't Need 30 Tools: Code Is Enough

This article explores a novel approach using a single-tool MCP server that accepts programming code as input. The author points out challenges with CLI tools, such as platform dependency, version dependency, and lack of documentation, making them difficult for agent tools to use. In contrast, an MCP server can maintain state and expose a single tool (e.g., a Python interpreter running eval()), allowing agent tools to better manage sessions and compose tools. The author demonstrates the effectiveness of this approach with pexpect-mcp, which transforms the MCP server into a stateful Python interpreter, simplifying debugging and improving efficiency. Furthermore, the author explores replacing Playwright's MCP with one exposing the Playwright API via JavaScript, reducing tool definitions and improving data transfer efficiency. While security concerns exist, the author argues this approach has significant potential and warrants further exploration.
