The Perils of Pseudo-Randomness: Why You Need True Random Numbers for Security

2025-05-31

RFC 4086 details the critical need for true randomness in security systems. Relying on pseudo-random numbers leaves vulnerabilities exploitable by sophisticated attackers who can recreate the environment to easily crack them. The document highlights the pitfalls of using low-entropy sources or traditional pseudo-random number generation techniques, advocating for true hardware random techniques such as leveraging sound cards, hard disk drives, or ring oscillators. It also provides mitigation strategies when hardware solutions are unavailable and illustrates the required size of random numbers for various applications.

Windows 11 Finally Overtakes Windows 10

With just three months until Microsoft ends support for Windows 10, Windows 11 has finally surpassed its predecessor in market share. July's StatCounter data shows Windows 11 at 50.24% and Windows 10 at 46.84%. This surge is largely attributed to enterprise migrations driven by the approaching end-of-support date, rather than a consumer-led boom. While sales of high-end devices like AI PCs remain sluggish, businesses are upgrading to Windows 11 or Windows 365 to avoid security risks.

Subaru STARLINK Flaw Lets Hackers Remotely Control Cars, Access PII

Security researchers discovered a critical vulnerability in Subaru's STARLINK connected car service. Attackers, knowing only a victim's last name and zip code, email, or license plate, could remotely start, stop, lock, unlock, and track vehicles. They could also access a year's worth of location history and retrieve sensitive personal information (address, billing details, etc.). The vulnerability allowed complete vehicle control and was patched within 24 hours. This highlights the critical need for enhanced security in connected car systems and robust user data protection.

Game-Changing Steel: Twisting Technique Creates Submicron 'Anti-Crash Wall'

Researchers from the Chinese Academy of Sciences, Shandong University, and the Georgia Institute of Technology have developed a novel twisting technique that dramatically enhances the fatigue resistance of stainless steel. By creating a submicron-scale, three-dimensional 'anti-crash wall' within 304 austenitic stainless steel, the technique significantly improves strength and reduces cyclic creep. Tests showed a 2.6-fold increase in strength and a 2-4 order of magnitude reduction in strain due to ratcheting, resulting in up to a 10,000-fold improvement in fatigue resistance. This breakthrough has potential applications in aerospace and other demanding industries.

Physics-Informed Neural Networks: Solving Physics Equations with Deep Learning

2025-02-17

This article introduces a novel method for solving physics equations using Physics-Informed Neural Networks (PINNs). Unlike traditional supervised learning, PINNs directly use the differential equation as a loss function, leveraging the powerful function approximation capabilities of neural networks to learn the solution to the equation. The author demonstrates the application of PINNs in solving different types of differential equations using the simple harmonic oscillator and heat equation as examples. Comparisons with traditional numerical methods show that PINNs can achieve high-accuracy solutions with limited training data, especially advantageous when dealing with complex geometries.

Hidden Gems in C's stdint.h: Beyond limits.h for Integer Type Definitions

Hidden Gems in C's stdint.h: Beyond limits.h for Integer Type Definitions

This blog post recounts the author's unexpected discovery about integer type definitions while learning C. In the early days of C, the size of integers varied greatly across different architectures, leading compiler vendors to create custom type definitions like Microware's types.h. Later, the ANSI C standard introduced stdint.h, providing standard type definitions like uint32_t and maximum value definitions like INT_MAX from limits.h. However, the author recently discovered that stdint.h also includes definitions like INT8_MAX and UINT32_MAX, which can be directly used to define the maximum and minimum values of integer types of specific sizes, making the code more portable and avoiding errors caused by platform differences.

Apollo 13: A Space Odyssey of Ingenuity and Survival

In 1970, Apollo 13's mission to the moon turned into a desperate fight for survival when an oxygen tank exploded, leaving three astronauts stranded 200,000 miles from Earth. Facing dwindling oxygen, power, and water, the crew found themselves in a critical situation due to insufficient carbon dioxide scrubbers. Ground control, in a feat of ingenuity, guided the astronauts through a makeshift repair using only materials available on board. They successfully modified the CO2 system, averting disaster and ensuring a safe return. This harrowing tale highlights human resilience and problem-solving in the face of unimaginable challenges.

Norwegian Startup's Airhull Tech Lets Electric Boats Glide on Air

Pascal Technologies, a Norwegian electric boat startup, is equipping two of its boats, the Nabcrew Zero AirBlue 1240 and Hugin DC, with Airhull technology. This innovative technology creates an air cushion under the hull, reducing drag and significantly increasing efficiency, potentially saving up to 50% of energy consumption. Simpler to implement than hydrofoil technology, Airhull uses a comb-like structure on the hull's underside and a blower at the bow to lift the boat 15-20cm out of the water. Suitable for boats from 6m to 30m, the technology is showcased on a 12m workboat (Nabcrew Zero AirBlue 1240) and a 9.15m leisure boat (Hugin DC), both slated for launch later this year.

FCC Approves Verizon's $20B Frontier Acquisition After DEI Policy Drop

The FCC, led by Chairman Brendan Carr, approved Verizon's $20 billion acquisition of Frontier Communications after Verizon pledged to end its diversity, equity, and inclusion (DEI) policies. Carr hailed the move as a positive step for equal opportunity and the public interest. This approval comes as Paramount Global and Skydance Media's $8 billion merger remains pending, potentially due to DEI concerns. Carr previously indicated he would block mergers involving companies promoting DEI programs. The acquisition allows Verizon to upgrade Frontier's network in 25 states, potentially bringing fiber to over 1 million homes annually.

Conquering JavaScript Fatigue: MESH, a Modular SSR Framework Built on HTMX

2025-09-23

Web development is facing "JavaScript fatigue" and "framework fatigue." This post explores using HTMX, a declarative approach to web development using HTML attributes, as a solution. However, HTMX's lack of structure led the author to create MESH, a modular server-side rendering (SSR) framework. MESH uses a "one component, one endpoint" model, leveraging Go and Web Components for SSR and hydration. Challenges with HTMX's inability to cross shadow DOM boundaries were overcome with clever workarounds. Real-time collaboration with Server-Sent Events (SSE) was also implemented. Ultimately, the author even removed HTMX entirely, using cleaner JS to achieve the same functionality, and reflects on the shortcomings and future directions of HTMX.
