OCR Challenge: Digitizing Saint-Simon's Memoirs

2024-12-17

The author spent several weeks using OCR to digitize a late 19th-century edition of the 18th-century French memoirs, *Les Mémoires de Saint-Simon*. This 45-volume behemoth, containing over 3 million words, is available online as images, but is difficult to read. The goal was to create a readable, searchable, and copyable text version. Challenges included poor image quality and parsing different page zones (headers, main text, margin comments, footnotes, etc.). Google Vision API was used for OCR, with a Python program processing the results to identify and separate text from different areas. While LLMs failed to reliably handle footnote references, the author improved the program and incorporated manual review, resulting in the release of the first volume.

DeepSeek's V3: Beating Benchmarks on a Budget

DeepSeek's new V3 model, trained on a mere 2,048 H800 GPUs—a fraction of the resources used by giants like OpenAI—matches or surpasses GPT-4 and Claude on several benchmarks. Their $5.5M training cost dwarfs the estimated $40M for GPT-4. This success, partly driven by US export controls limiting access to high-end GPUs, highlights the potential for architectural innovation and algorithmic optimization over sheer compute power. It's a compelling argument that resource constraints can, paradoxically, spur groundbreaking advancements in AI development.

Upgrading Capitalism: A Survival Guide

The author recounts personal experiences of the dot-com bubble burst in 2000 and the 2008 financial crisis, highlighting the inherent instability within capitalism despite its undeniable successes. He argues that while capitalism has lifted billions out of poverty, its core is inherently unstable. With a potential 'Papa Bear' level crash looming, the author suggests that ignoring the risks is as dangerous as blindly fighting the system. The essay calls for upgrading capitalism – retaining its strengths while mitigating its flaws – and invites readers to join the crucial conversation.

Bloom Filters: The Secret to Making SQLite 10x Faster

2024-12-22

Researchers cleverly used Bloom filters to make SQLite analytical queries 10x faster. They discovered that SQLite's nested loop joins were inefficient, with much time spent on B-tree probes. By using a Bloom filter before the join operation to quickly filter out rows unlikely to match, and then performing B-tree probes only on potential matches, the number of probes was significantly reduced. Bloom filters have minimal memory overhead and were easy to integrate into SQLite's existing query engine, resulting in a significant performance boost. This improvement has been integrated into SQLite v3.38.0.

Angel Investor Hits Pause After 15 Years: A Deep Dive into the Why and What's Next

After 15 years and 54 investments, an angel investor decided to pause his angel investing activities. He found that over-diversification led to superficial founder relationships, limited learning opportunities, and returns that didn't justify the time commitment, risk, and opportunity cost. His future plans involve deeper founder engagement through board positions, learning through podcasting and teaching, and becoming an LP in VC funds. He concludes that sometimes, the best investment decision is not to invest at all.

Reliable Data Sending with JavaScript's Beacon API: Ditching Unreliable `beforeunload`

Reliable Data Sending with JavaScript's Beacon API: Ditching Unreliable `beforeunload`

Sending data reliably to servers when a user leaves a website has always been a challenge. Traditional methods using the `beforeunload` event with `fetch` or `XMLHttpRequest` are unreliable, as browsers may cancel requests for a better user experience. JavaScript's Beacon API offers a 'fire-and-forget' solution; the browser doesn't wait for a response, ensuring data is sent reliably. While the Beacon API limits data size and only supports POST requests, it's perfect for sending small, critical data like analytics or page leave events. It's also great for any scenario requiring reliable asynchronous data sending, such as real-time data synchronization.

Speed, Anxiety, and the Echoes of 1910 in the 21st Century

This article explores the unsettling parallels between the anxieties of the early 20th century, marked by rapid technological advancements (automobiles, airplanes, bicycles), and the challenges facing our own time. Drawing from Philipp Blom's 'The Vertigo Years,' it recounts the pervasive anxiety and mental strain resulting from the accelerated pace of life, and how artists responded through their work. From the widespread prevalence of neurasthenia to the birth of abstract art, the author argues that modernism wasn't simply a reflection of modernity, but a reaction to it. The piece delves into the contrasting yet complementary theories of Max Weber and Sigmund Freud, offering sociological and psychological perspectives on the roots of this anxiety. It ultimately prompts reflection on the relationship between technological progress and human nature: is technological advancement the ultimate expression of our humanity, or its ultimate threat?

Tesla's German Nightmare: Musk's Politics Tank Sales

2025-03-14

A survey of over 100,000 Germans reveals that 94% won't buy a Tesla. This is disastrous news for Tesla, whose sales have plummeted in the crucial European market. In 2024, despite a 27% surge in overall EV sales, Tesla saw a 41% sales drop in Germany. The first two months of 2025 saw a further 70% decline. Industry experts blame Elon Musk's meddling in German elections and support for the far-right AfD party. Musk is under investigation in Europe, and his reputation in Germany is severely damaged. A new survey shows only 3% of respondents would consider buying a Tesla. German consumers are clearly rejecting the brand.

The Evaporative Cooling Effect in Social Networks: Why High-Value Contributors Leave

2025-01-07

This blog post explores the 'evaporative cooling effect,' where high-value contributors leave a community due to lack of benefit, leading to a decline in community quality. It analyzes how factors like openness, community access mechanisms (e.g., paid membership or knowledge barriers), internal communication styles, and rewarding high contributors affect this effect. The author argues that 'evaporative cooling' is inevitable in community growth, and the key is to slow it down. The post suggests combining 'plaza' (easily expandable) and 'warren' (more stable) community structures to balance scalability and stability.

In a final push before leaving office, the Biden administration plans to further restrict the export of AI chips from companies like Nvidia, aiming to prevent advanced technologies from reaching China and Russia. New regulations will create three tiers of restrictions: close allies will face minimal limits; adversaries will be effectively blocked; and most countries will face limits on total computing power, though higher caps can be obtained by meeting US security and human rights standards. Nvidia opposes the proposal, arguing it will harm economic growth and US leadership.

Wayland's Fragmentation: A Cross-Desktop Compatibility Nightmare

2025-06-17

Wayland's design omits basic functionality enjoyed by X11, Windows, and macOS applications for decades—like window positioning and mouse cursor control. This wasn't an oversight; it was intentional. Further compounding the issue is fragmentation: GNOME, KDE, and other compositors interpret Wayland protocols differently. Application developers can't rely on consistent implementations, leading to unsustainable support burdens, especially for niche applications on already-fragmented Linux. Worse, these problems reside in Wayland protocols, window managers, and compositors—beyond the reach of application developers. We hope the Wayland ecosystem matures, but we aren't there yet.
