How a Browser Silently Blocks RWX Execution

2025-01-08
How a Browser Silently Blocks RWX Execution

A security researcher discovered a browser's EDR-like mechanism that blocks RWX shellcode execution. By hooking the BaseThreadInitThunk() API, the browser intercepts thread creation and checks if the shellcode memory attributes are PAGE_EXECUTE_READ. If not, it redirects the thread's execution to a 'sinkhole', preventing malicious code from running. While simple, this unexpected feature highlights a browser's proactive security measures, significantly increasing the difficulty of exploiting RWX memory regions.

Indiana University Professor Under Investigation for Undisclosed Chinese Research Funding

Indiana University (IU) data privacy professor Xiaofeng Wang and his wife are under investigation for allegedly failing to disclose research funding received from China. The university began reviewing whether Wang received unreported funding months before the FBI raided two of the couple’s homes last week. A statement, purportedly written by a long-time collaborator, reveals IU contacted Wang in December about a 2017-2018 Chinese grant listing him as a researcher. The statement alleges IU was concerned Wang failed to properly disclose the funding to the university and in US federal grant applications. While Wang claims to have explained the situation, the investigation continues. The allegations involve research misconduct, including failure to properly disclose the principal investigator and not fully listing co-authors. Wang regularly collaborated with researchers at the Chinese Academy of Sciences' Institute of Information Engineering, but his publications show his primary funding came from US government agencies and corporations. No evidence currently suggests impropriety in the collaborations.

My Programming Habits Have Changed Thanks to Claude Code: Farewell Python, Hello Type Safety

2025-08-04

My programming habits have drastically changed since using Claude Code. For over 10 years, Python was my go-to language, but now I'm comfortably managing projects in TypeScript, Rust, and Go, even though I'm not fully fluent in them. The safety guarantees of typed, compiled languages make them surprisingly well-suited for 'vibe coding,' a style I previously associated solely with Python. Paradoxically, with larger projects, Claude Code combined with languages like Rust is faster and safer than with Python, purely due to AI-assisted development. For example, refactoring large parts of our TypeScript frontend code, Claude Code's integration with tsc ensures compile-time safety, letting me make substantial changes (3-5k lines) in hours without breaking anything. While LLMs aren't perfect, they offer the speed of Python prototyping without its drawbacks, leading me to predict decreased Python adoption in production deployments.

Revolutionary Idea: Applying Magit Principles to the jj Version Control System

2024-12-13

The author proposes a novel approach: applying the Magit version control interface from Emacs (which uses text files as its UI) to the nascent jj version control ecosystem. The article points out that Magit's text-based UI offers efficiency and portability. By leveraging the LSP protocol, a Magit-like experience can be implemented in various editors, avoiding redundant development. The author envisions generating specific text files (such as .jj/status.jj) and utilizing LSP features like semantic tokens, folding ranges, and goto definition to achieve Magit-like version control operations. The ultimate goal is to create a cross-platform, efficient user interface for jj version control.

Kafka: Insurance Clerk, Workers' Advocate

Franz Kafka, famed for works like *Metamorphosis* and *The Trial*, held a lesser-known position at the Workers' Accident Insurance Institute in Prague. This seemingly mundane job became a window into societal ills, allowing Kafka to investigate factory conditions and anonymously expose corporate negligence to the press. He championed workers' rights, advocating for improved safety regulations and ultimately contributing to better conditions for Bohemian workers. This reveals a different side to Kafka, beyond his literary persona: a dedicated advocate for social justice.

Concussions May Reactivate Herpes Virus, Triggering Alzheimer's

Researchers at Tufts University used a 3D mini-brain model to demonstrate that simulated concussions can reactivate latent herpes simplex virus type 1 (HSV-1) in brain tissue, leading to Alzheimer's-like inflammation, amyloid plaques, and neuron death. This research connects HSV-1 infection, head trauma, and Alzheimer's for the first time, providing new evidence for the microbial theory of Alzheimer's and suggesting antiviral drugs as a potential preventative treatment. The findings indicate that head injuries, such as concussions, may reactivate dormant HSV-1, increasing the risk of Alzheimer's disease.

Childhood Leukemia: From Death Sentence to Treatable Disease

Before the 1970s, childhood leukemia was a death sentence, with less than 10% of diagnosed children surviving five years. Today, in North America and Europe, that survival rate has soared to around 85%! This dramatic turnaround is due to a series of breakthroughs: collaborative research leading to more effective chemotherapy regimens, personalized treatments based on risk stratification, the development of targeted drugs and immunotherapies fueled by molecular research, and improved supportive care. This is a testament to the power of scientific collaboration and a model for what medical research can achieve.

Social Media: Incitement or Hype? A Debate on Political Polarization

Social Media: Incitement or Hype? A Debate on Political Polarization

This article delves into the impact of social media on political polarization. The author challenges Dan Williams' argument that social media's influence is overstated. While acknowledging long-term polarization trends, the author contends that social media amplifies negative emotional content, empowers elite political influencers, and exacerbates political conflict and extremism. An 'elite radicalization' theory is proposed, suggesting that social media algorithms promote the spread of negative emotions, shaping public perception and leading to increased offline extreme political behavior, supported by empirical studies. Therefore, even if social media's impact on partisan polarization is limited, its negative effects on the political landscape remain significant.

Non-Cryptographic Hash Functions: Design and Evaluation

2025-02-15

This article delves into the design and evaluation of non-cryptographic hash functions. By analyzing the performance of common functions like FNV-1a, FNV-1, Murmur2, and DJBX33A on diverse datasets (including names, words, IP addresses, and a deliberately biased dataset), the authors reveal key characteristics such as uniformity, collision rate, and avalanche effect. Experiments show Murmur2 excels in the avalanche effect but isn't always optimal for uniformity. The article stresses the importance of dataset characteristics in choosing appropriate hash functions and questions existing evaluation criteria, arguing that a single metric (like the avalanche effect) is insufficient for comprehensively assessing non-cryptographic hash function performance.
