DeepSeek, Open-Source AI Startup, Shifts Focus to Monetization

Chinese AI startup DeepSeek has updated its business registration, signaling a shift towards monetizing its cost-efficient large language models (LLMs). The updated scope includes "internet information services," indicating a move away from pure R&D and towards a business model. This follows the release of their open-source LLMs, previously developed with a research-focused approach. The company, spun out of hedge fund High-Flyer, has yet to comment on this strategic change.

Adaptive Hashing in SBCL: Making Hash Tables Faster and More Robust

2025-05-11

A talk at the 2024 ELS focused on adaptive hashing, aiming to make general-purpose hash tables faster and more robust. Traditional hash table theory primarily concerns itself with asymptotic worst-case costs, neglecting the impact of constant factors on real-world performance. This research introduces an online adaptive approach, adjusting the hash function based on the actual key distribution to reduce collisions and improve cache utilization. Experiments demonstrate significant improvements in reducing expected comparisons and speeding up PUT operations, particularly with specific key distributions. SBCL's built-in hash tables now employ this technique, dynamically switching hash functions (including linear search, bit-shifting hash, and MurmurHash) based on collision counts and hash table size. For composite keys like strings and lists, a truncation strategy is used, dynamically adjusting the truncation length when too many collisions occur. This improvement enhances SBCL hash table speed in common cases and robustness in others.

The Hidden Engineering of Wildlife Crossings

The Wallis Annenberg Wildlife Crossing, a $92 million project near Los Angeles, is the world's largest wildlife crossing of its kind. This article delves into the engineering behind these vital structures, addressing the challenges of habitat fragmentation, noise pollution, and wildlife-vehicle collisions caused by roads. It explores various design aspects, including site selection, crossing types (underpasses, overpasses, culverts), fencing strategies, and attracting animals to use the crossings. The article highlights the different crossing behaviors of various species and corresponding engineering solutions, such as elevated bridges for large animals and culverts for smaller ones. Design considerations include animal behavior, topography, vegetation, and ensuring the crossings blend seamlessly into the landscape, minimizing human-wildlife conflict.

Protocol Buffers: An Amateur Disaster?

2025-09-05

This article criticizes the design flaws of Protocol Buffers (protobuf), arguing that its type system is poor, its design is ad-hoc, and that it leads to a series of problems that permeate the code. The many restrictions of protobuf stem from its poor solutions to already-solved problems, lacking compositionality. Examples include the inability to repeat oneof fields, and various map field limitations. The article also criticizes protobuf's claims of hassle-free backwards and forwards compatibility, and how it pollutes codebases, making code difficult to write and maintain. The author argues that protobuf is only suitable for large companies like Google, not for most companies, and advises developers to abandon the use of protobuf.

Slashing AWS Bandwidth Costs by 95%: The dm-cache Story

Upsun dramatically reduced its AWS bandwidth costs by leveraging underutilized local SSD storage on its instances. Using Linux's dm-cache, they implemented a read cache for their Ceph-based network storage. By caching frequently accessed data blocks locally, they minimized costly inter-AZ traffic. Employing a write-through policy ensured data integrity, resulting in a 95% reduction in bandwidth costs, a 30x IOPS improvement, and significant performance gains for their e-commerce applications. The key was exploiting the locality of reference inherent in application I/O patterns.

Google Translate Breaks React (and other Web Apps): A DOM Showdown

Google Translate, Chrome's built-in extension, manipulates the DOM in a way that breaks many modern web apps, particularly those using React. The article dives deep into how Google Translate works, replacing TextNodes with FontElements, disrupting React's Virtual DOM and causing crashes or data inconsistencies. Common errors like `NotFoundError` and `insertBefore` failures are analyzed, along with workarounds such as monkey patching and wrapping TextNodes in `` elements, but these solutions have limitations. Ultimately, the article suggests developers weigh the pros and cons, potentially disabling Google Translate or implementing their own localization to ensure app stability and user experience.

Undocumented Power Macintosh G3 Easter Egg Discovered After 27 Years

2025-06-24

A developer accidentally stumbled upon an undocumented easter egg hidden within the ROM of the original Power Macintosh G3. The egg is a JPEG image featuring the team who worked on the Mac models. By analyzing the SCSI Manager code in the ROM, the developer discovered the trigger: formatting the RAM disk after startup and typing 'secret ROM image' into the format dialog. This creates a JPEG file named 'The Team' on the RAM disk, revealing the team photo. This find might be one of the last easter eggs on Macs before their reported banning in 1997, adding a layer of mystery to Mac history.

First Fatal Crash Involving a Driverless Car

A multi-vehicle crash in San Francisco marks the first fatal collision in the U.S. involving a fully autonomous vehicle with no one behind the wheel. While a Waymo self-driving car was involved, it wasn't at fault; a speeding vehicle hit a line of stopped cars, resulting in one human fatality and the death of a dog. Despite Waymo's claim of superior safety records compared to human drivers, based on millions of miles driven, the incident raises serious questions about the safety of autonomous vehicles and will likely trigger further scrutiny of the technology.

To Compile or Not to Compile Database Queries: A Deep Dive

2025-02-12

This article explores the trade-offs of compiling database queries. Traditional query interpreters struggle with the speed of modern NVMe SSDs, leading to significant performance bottlenecks. Compiling queries offers substantial speed improvements, especially for OLAP workloads. However, compilation time and optimization challenges create unpredictable performance cliffs. Vectorized interpreters, conversely, are easier to build, debug, and offer more consistent performance. The article contrasts this with browser JavaScript/Wasm engines, which use a tiered compilation approach (interpreter, baseline compiler, optimizing compiler) to achieve a smooth performance trade-off. The author proposes a similar approach for databases, suggesting a baseline compiler as a key component. Several implementation strategies, including 'copy-and-patch' and Wasm compilation, are explored. Ultimately, the article argues that building a baseline compiler isn't prohibitively difficult and offers perspectives on future directions.
