Hong Kong Consumer Council: Shocking Sunscreen Efficacy Test Results!

The Hong Kong Consumer Council tested 30 daily-use sunscreens, revealing alarming results! Over 80% performed below their labeled SPF, with some high-SPF sunscreens measuring below SPF15. Many also failed to meet labeled UVA protection levels and ingredient disclosure requirements. The Council urges manufacturers to improve production and labeling accuracy, providing clear instructions. Consumers are advised to choose carefully to avoid inadequate sun protection and potential skin damage.

Microdot: A Tiny Web Framework for Microcontrollers

2025-09-07

At EuroPython 2025, Miguel Grinberg presented Microdot, a lightweight web framework running on both MicroPython and CPython, suitable for systems ranging from IoT devices to cloud servers. Inspired by Flask but significantly smaller, Microdot's creation stemmed from Grinberg's experience with a faulty smart thermostat in his Irish home. He built a MicroPython-based system to control heating and used Microdot to create a simple web interface for monitoring temperature and humidity. Microdot's core is remarkably concise at 765 lines of code, supporting asynchronous operations and common features, with extensions providing advanced functionality. Its design emphasizes simplicity and avoids complexity, making it ideal for building web applications on microcontrollers.

Roku Streaming Surpasses Traditional TV Viewing in the US

Nielsen data reveals that for the third consecutive month, US viewers spent more time streaming on Roku devices than watching traditional broadcast television in July. Roku-powered devices accounted for 21.4% of all TV viewing, surpassing broadcast TV's 18.4%. This signifies a major shift in viewing habits. Roku's success isn't solely attributed to its own streaming service, The Roku Channel, but also its vast ecosystem of thousands of apps and live TV providers. Roku aims to be more than a content provider; it aspires to be the gateway to modern television.

Anonymous Recursive Functions in Racket: The lam/anon♻️ Macro

Racket programmers often find themselves writing anonymous functions and realizing mid-way that recursion is needed. Traditional solutions require rewriting code, introducing `letrec`, increasing indentation, and adding complexity. This article introduces a macro called `lam/anon♻️` that enables anonymous recursive functions in Racket without explicit naming. It mimics PowerShell's syntax by binding `$MyInvocation`, simplifying code and improving efficiency. While Racket already offers `rec` for similar functionality, `lam/anon♻️` provides a more concise approach to anonymous recursion.

Say Goodbye to Redundant CLI Validation: Introducing Optique

Tired of writing repetitive command-line argument validation code? The author shares their experience building the Optique library. Optique leverages parser combinators to directly parse command-line arguments into the expected type, eliminating the need for subsequent validation and avoiding issues like validation logic getting out of sync with options. TypeScript's type inference catches errors at compile time, significantly improving development efficiency and code reliability.

Shocking! Online Poker Game's Card Shuffling Algorithm Exploited by Hackers!

In the late 1990s, a serious flaw was discovered in the card shuffling algorithm of an online poker game. The algorithm used the computer's system time to generate random numbers, but due to limitations in its mechanism, the number of possible card combinations generated was far less than the theoretical value, only about 200,000 possibilities. This meant hackers could easily predict the outcome of the game by synchronizing their system time with the game's, allowing them to manipulate the game. This incident highlights the importance of algorithm security and warns developers about the risks of relying on random number generators.

Water-Walking Robot Inspired by Ripple Bugs

Scientists have created a tiny robot called Rhagobot, inspired by Rhagovelia water striders (also known as ripple bugs). These semiaquatic insects glide effortlessly across water thanks to unique fan-like appendages on their middle legs. Rhagobot mimics this adaptation, using passively morphing structures that adjust to water flow for propulsion. The five-year study, published in Science, reveals the previously unknown intricate structure of the water strider's legs and provides insights into developing self-morphing artificial propellers for semi-aquatic robots.

Stop Shipping PNGs as Game Textures!

Still using PNGs for game textures? This post explains why that's suboptimal and introduces a better approach. While PNGs are great for interchange, they weren't designed for texture data and lack support for GPU-compatible texture compression (like BCn), leading to slow loading times and high VRAM usage. The author advocates for texture formats like KTX2 or DDS, providing an open-source tool, Zex, to convert PNGs to KTX2 with BC7 compression and zlib supercompression. Tips on pregenerating mipmaps and automating the conversion process are also shared, along with a recommendation to use Tacentview for viewing texture formats.

Smalltalk MVC: Untangling the Misconceptions of Model-View-Controller

2025-09-07

This article delves into the Smalltalk MVC pattern, clarifying long-standing misconceptions surrounding MVC, particularly the deviations in Apple's Cocoa version. The author emphasizes the independence and reusability of the model in Smalltalk MVC, noting that the model interacts with the view and controller only indirectly through notifications. This contrasts with the Cocoa version of MVC, where controllers (and now view controllers) often become the least reusable components. The article further explains how to correctly identify models, ranging from simple observable booleans to complex models, and how to handle view models and function argument models to build cleaner, more maintainable application architectures.

Pushing Linux File I/O Performance to the Limit with Zig and io_uring

2025-09-07

This post explores maximizing file I/O performance on Linux using Zig and io_uring. A custom Zig implementation is benchmarked against fio, achieving write speeds of 3.802 GB/s and read speeds of 6.996 GB/s—slightly slower than fio's 4.083 GB/s write and 7.33 GB/s read speeds but still within expected ranges. The author details crucial implementation techniques, including polled I/O, registered buffers, and the SQ_THREAD_POLL feature, all significantly impacting performance. While marginally slower than fio, the Zig code's performance is remarkably close, and its runtime almost exactly matches fio's, suggesting minor differences in bandwidth measurement.

Rare Kimsuky Leak Reveals Tactics and Infrastructure of North Korean-Linked APT

A rare security incident involving a data breach attributed to a North Korean-affiliated actor, dubbed “Kim,” offers unprecedented insights into Kimsuky (APT43) tactics, techniques, and infrastructure. The group focuses on credential-centric intrusions targeting South Korean and Taiwanese networks, blending Chinese-language tooling, infrastructure, and potential logistical support. The “Kim” dump, containing bash histories, phishing domains, OCR workflows, compiled stagers, and rootkit evidence, reveals a hybrid operation between DPRK attribution and Chinese resource utilization. The leaked data includes malware development, OCR parsing of Korean PKI and VPN documents, and reconnaissance targeting Taiwanese government and academic institutions. Analysts uncovered an advanced Linux rootkit employing syscall hooking and stealth persistence. The incident highlights the evolving capabilities of North Korean threat actors and their potential connections to Chinese resources.

Gut Bacteria Leakage Exacerbates Liver Damage in Chronic Alcohol Use: A New Mechanism

Gut Bacteria Leakage Exacerbates Liver Damage in Chronic Alcohol Use: A New Mechanism

A new study uncovers a previously unknown mechanism by which chronic alcohol consumption worsens liver damage. Research reveals that chronic alcohol use impairs the production of the cellular signaling protein mAChR4 in the small intestine. This protein is crucial for the formation of goblet cell-associated antigen passages (GAPs), which help the immune system identify and respond to gut bacteria escaping into other parts of the body. Lower mAChR4 levels weaken GAP formation, allowing gut bacteria to leak into the liver, exacerbating alcohol-related liver damage. Fortunately, restoring mAChR4 function can repair the immune response and lessen liver damage. Published in Nature, this research offers a potential new therapeutic target for alcoholic liver disease and may also offer insights into treating alcohol use disorder.
