Saying Goodbye to CSS Classes: Building a Classless Website

Saying Goodbye to CSS Classes: Building a Classless Website

Following a previous post advocating for leveraging browser built-in elements, the author put this philosophy into practice by completely removing all CSS classes from his personal website. He experimented with more granular default styles, nested selectors, modern CSS features like `:where()` and `:has()`, and custom elements and attributes as replacements. While this requires more careful planning and isn't suitable for all projects, the experiment led the author to question the necessity of CSS classes and has had a lasting influence on his future work. A small concession was made for a syntax highlighting plugin which utilizes classes.

pnpm Update: Delayed Dependency Updates and Advanced Dependency Finding

The latest pnpm release introduces two significant features: First, a new `minimumReleaseAge` setting delays the installation of newly released dependencies to mitigate security risks. Second, it adds support for finder functions in `.pnpmfile.cjs` allowing for custom search rules via `pnpm list` or `pnpm why` with the `--find-by` flag, enabling more granular dependency searching; for example, finding packages with a specific React version in their peerDependencies. Bug fixes include resolving deprecation warnings in Node.js 24 and ensuring a non-zero exit code when a process is cancelled with Ctrl-C.

OpenAI Admits: AI Hallucinations Stem from Fundamental Training Flaws

OpenAI Admits: AI Hallucinations Stem from Fundamental Training Flaws

OpenAI has published a paper revealing that the 'hallucinations' in its large language models aren't accidental; they're a consequence of fundamental flaws in the training methodology. Models are trained to prioritize guessing over admitting ignorance, as this yields higher scores in current evaluation systems. The paper uses the example of finding a researcher's birthday to demonstrate how the training mechanism leads to incorrect answers. OpenAI acknowledges that mainstream evaluation methods reward this 'hallucinatory' behavior and states it's improving training mechanisms, such as prompting models to more frequently respond with 'I don't know,' but completely resolving the issue remains a challenge.

Congress Summons CEOs of Discord, Steam, Twitch, and Reddit Over Online Radicalization

The House Oversight Committee has summoned the CEOs of Discord, Steam, Twitch, and Reddit to testify on October 8th regarding the radicalization of online forum users on their platforms. The investigation stems from the killing of right-wing activist Charlie Kirk, with the suspect allegedly using Discord to discuss the event. These platforms have a history of hosting extremist content, with past incidents including the 2017 Unite the Right rally and the 2022 Buffalo and Highland Park shootings linked to their use.

Sony Quietly Releases Downgraded PS5 Digital Edition with 825GB SSD

Sony has quietly released a revised PlayStation 5 Digital Edition (CFI-2116) with a reduced 825GB SSD, down from the previous 1TB. While the price remains the same, this move is speculated to be a cost-cutting measure in response to economic challenges. The change has sparked debate among gamers, with some arguing the 200GB reduction is insignificant, while others worry about the 1TB version's availability. The revised console is currently available on select European Amazon sites, with its future availability in other regions uncertain.

Self-Healing Organogel Stretches 46x its Size and Repairs Itself

Scientists in Taiwan have created a self-healing organogel that can stretch up to 46 times its original length. Even when broken, it repairs itself completely within 10 minutes at room temperature. This remarkable material combines covalently linked cellulose nanocrystals and modified mechanically interlocked molecules (MIMs) acting as artificial muscles. These muscles make the gel responsive to external forces, changing color from orange to blue depending on its state. Its self-healing and color-changing properties show promise for applications in flexible electronics, soft robotics, and anti-counterfeiting.

Manually Decoding GZIP: A Deep Dive into the Deflate Algorithm

2025-09-18

The author attempts to manually decode the string "TOBEORNOTTOBEORTOBEORNOT" compressed with GZIP, providing a deep dive into the Deflate algorithm. The article details the GZIP data structure, including magic numbers, compression methods, timestamps, and other fields. It focuses on the core of Deflate compression—the LZ77 algorithm. LZ77 uses characters and copy commands (length and distance) for encoding, effectively reducing data size. By manually parsing the compressed data, the author reconstructs the original string step-by-step. The conclusion: bit encoding is more efficient than byte encoding for data compression, but manual decoding is complex.

Malicious npm Packages Published via Compromised GitHub Actions Workflow

A malicious GitHub Actions workflow exfiltrated an npm token with broad publishing rights from a shared repository, leading to the publication of malicious versions of 20 packages, including the popular @ctrl/tinycolor. While the author's GitHub account and repository weren't directly compromised, a collaborator with admin access to a shared repository allowed the attack to succeed. The attackers exploited a GitHub Actions secret containing the npm token. GitHub and npm security teams swiftly responded, unpublishing the malicious packages. The author released clean versions to clear caches. The incident highlights the risks of shared repositories and static tokens, prompting a move towards npm's Trusted Publishing (OIDC) for enhanced security.

Ant Queens Cloning Males of a Different Species: Rewriting the Rules of Reproduction

Iberian harvester ant (Messor ibericus) queens are defying reproductive biology norms by cloning males of an entirely different species, Messor structor. Researchers discovered isolated M. ibericus colonies thriving without nearby M. structor populations. This led to the astonishing revelation that M. ibericus queens produce male M. structor offspring, which then father the colony's workers. This is the first documented case of an animal producing offspring from another species as part of its normal life cycle, challenging established understanding of species barriers and highlighting the unexpected complexity of natural cooperation and conflict.

Rendezvous Hashing: A Distributed Hashing Algorithm with Excellent Load Balancing

2025-09-18

Rendezvous hashing solves the distributed hash table problem by generating a prioritized server list for each key and selecting the first server. Unlike consistent hashing, it offers superior load balancing but has an O(N) lookup time. It's a good choice for small to medium-sized distributed caches, but adding servers in larger systems requires careful management to maintain the "first choice" invariant. Its popularity lagged behind consistent hashing, possibly due to a lack of a 'killer app' moment, despite its earlier invention and inherent advantages.

YouTube View Count Drop: Are Ad Blockers to Blame?

YouTube View Count Drop: Are Ad Blockers to Blame?

Many YouTubers have recently reported significant drops in video view counts. The most plausible explanation points to YouTube not accurately counting views from users with ad blockers enabled, a potential escalation in YouTube's ongoing battle against ad blockers. Several creators noticed a roughly 50% drop in computer views, while mobile and tablet views remained steady. While YouTube denies a systemic issue, it acknowledges that ad blockers can impact view count accuracy. Other explanations, such as seasonal viewing habits and platform competition, exist, but the ad blocker theory seems the most likely, especially since ad revenue hasn't decreased.

The LLM Hype Bubble Bursts: The Rise of Small Language Models

2025-09-18

The initial excitement surrounding large language models (LLMs) is fading, with many companies yet to see a return on investment. The author argues that we've been fooled by LLMs' fluent language, mistaking it for genuine intelligence. The future, they suggest, lies in smaller, more distributed models, mirroring the evolution of dynamo technology. Small language models (SLMs) will focus on smaller, more specific language tasks, such as query rewriting, rather than attempting to mimic human intelligence. This will lower costs, increase efficiency, and reduce ethical concerns. Instead of pursuing 'intelligent' applications, the author advocates using LLMs for their strengths in low-level language processing, such as proofreading and text summarization. This, they argue, is the true path forward for LLMs.
