Truchet Tiles: Simple Geometry, Infinite Possibilities

2025-07-29

Truchet tiles, simple square tiles with non-rotationally symmetric patterns, create surprisingly complex and captivating visual effects. First described in 1704 by Sébastien Truchet, they're now widely used in information visualization and graphic design. By varying the tile orientations, diverse patterns emerge, even creating labyrinths. Their elegant simplicity extends to programming; a single line of code can generate endless variations, highlighting the beauty of concise algorithms and infinite possibilities. This makes them a prime example of generative art.

Anker Appears to Be Abandoning Its 3D Printer Business

Anker's EufyMake brand has quietly stopped selling its AnkerMake M5 and M5C 3D printers and key accessories, leading to speculation that Anker is abandoning the 3D printing business. While Anker claims sales are paused and future models are possible, the printers are currently unavailable on the website, and critical components like the M5C hotend are also out of stock, leaving users frustrated. This follows Anker's rocky start in 3D printing, with its products plagued by quality issues. In contrast, companies like Creality and Bambu have gained market share through rapid iteration and improvement.

Sentry: Redefining Enterprise Software – The Fortune 500,000 Approach

2025-02-11

Sentry, with over 50,000 paying customers, challenges traditional enterprise software models. The author argues that focusing on building a product every customer wants, at a reasonable price, and targeting the "Fortune 500,000" is a superior strategy to the legacy model of solely focusing on large enterprises. This product-led growth approach prioritizes community building, branding, and low-friction customer experience over massive sales teams. The author claims this model isn't just viable but also efficient and measurable, offering a new pathway for enterprise software companies.

Dissecting a Minimalist Transformer: Unveiling the Inner Workings of LLMs with 10k Parameters

This paper presents a radically simplified Transformer model with only ~10,000 parameters, offering a clear window into the inner workings of large language models (LLMs). Using a minimal dataset focused on fruit and taste relationships, the authors achieve surprisingly strong performance. Visualizations reveal how word embeddings and the attention mechanism function. Crucially, the model generalizes beyond memorization, correctly predicting "chili" when prompted with "I like spicy so I like", demonstrating the core principles of LLM operation in a highly accessible manner.

Heat Pumps Surpass Gas Furnaces in US Sales: A Clean Energy Win?

Heat pump sales in the US surged 37% in the first 11 months of the year, outpacing gas furnaces to become the most popular heating appliance. This 21% year-over-year increase is driven by their superior efficiency, lower carbon emissions, and technological advancements enabling use in colder climates. While installation costs remain high ($17,000-$30,000), government incentives (like the Inflation Reduction Act) and growing consumer awareness are boosting adoption. However, price, compatibility issues, and concerns about grid reliability remain barriers. Future growth hinges on effective communication highlighting long-term savings and improved home comfort.

Rust Ring Buffers: A Deep Dive

2025-02-20

While working on a MIDI project, the author needed a way to store recent messages without unbounded memory growth. A ring buffer proved to be the solution. This post explains ring buffers, their functionality, and use cases. It compares Rust's standard library `VecDeque` with third-party libraries like `circular-buffer` and `ringbuffer`. `VecDeque` offers flexibility but resizes dynamically; fixed-size alternatives like `circular-buffer` and `ringbuffer` avoid reallocation overhead but are less flexible. The author concludes that for fixed-size needs, third-party libraries save development time and effort.

Don't Roll Your Own Crypto: Why Developers Keep Failing at Encryption

Developers often mistakenly believe that using lower-level cryptography libraries avoids the risks of 'rolling their own crypto.' This article argues that many developers misunderstand cryptography, and even using existing libraries doesn't guarantee security if mistakes are made in protocol design or key management. The author presents real-world examples and stresses the importance of robust key management and the need for developers to deeply understand and have expert review of their cryptographic implementations.

The Secret Language of Movie Poster Colors: A Data-Driven Analysis

An analysis of nearly 60,000 movie posters reveals a fascinating correlation between film genre and color palette. Orange emerges as the most frequently used color, often paired with yellow in comedies, adventures, and family films to evoke warmth and fun. Action, sci-fi, and thrillers utilize the contrast between orange and blue to emphasize spectacle and conflict. Red is prevalent across horror, action, and romance, but its meaning shifts depending on context. Blue frequently represents oceanic or atmospheric settings, while green dominates in animation, family, and adventure films. Purple and pink often signal unconventional films, highlighting their unique style. This research provides data-backed insights for movie poster design, revealing the patterns of color usage across different genres.

The German parliament rejected a proposal to supply Ukraine with Taurus cruise missiles. The proposal urged the government to provide missiles, assist in integrating them into Ukrainian aircraft, train Ukrainian soldiers, remove obstacles to information sharing, replenish the Bundeswehr's equipment, increase industrial production capacity, and procure more missiles. The decision likely reflects concerns about escalating the conflict and the potential uses of the missiles.

Telegram's Security Flaw: A Russian Network Engineer's Secret Ties to the Kremlin

A new investigation reveals a critical vulnerability in Telegram, the wildly popular messaging app. It finds that the maintenance of Telegram's networking equipment and assignment of its IP addresses are controlled by a virtually unknown Russian network engineer, Vladimir Vedeneev. Vedeneev's companies have close ties to Russian security services, having served clients including the FSB. While there's no evidence of direct government data sharing, it raises serious questions about Telegram's claims of security and privacy, especially given its default lack of end-to-end encryption. This discovery highlights how even seemingly secure messaging apps can be vulnerable to exploitation.

The Chrome permissions team is experimenting with a new declarative HTML `` element to simplify how web apps request powerful features like location access. Traditional imperative methods suffer from permission spam, poor contextualization, and difficulty in revoking permissions. The `` element offers a more secure and user-friendly approach, allowing developers to declaratively request permissions while the browser dynamically updates the element's text based on user interaction and provides clear permission management. Currently in origin trial in Chrome 126, it aims for standardization.

Optimizing a Rust AV1 Decoder: Avoiding Unnecessary Zeroing and Optimizing Struct Comparisons

By comparing the performance of the Rust-based AV1 decoder rav1d and the C-based dav1d, the author, using a sampling profiler, identified two performance bottlenecks. The first was unnecessary zeroing of a buffer in rav1d on ARM architecture, leading to performance degradation. The second was an inefficient implementation of struct comparisons in rav1d. By using `MaybeUninit` to avoid unnecessary zeroing and optimizing struct comparisons, the author improved rav1d's performance by almost 2%.
