Roula Khalaf, Editor of the FT, offers a free Editor’s Digest newsletter filled with her favorite stories. In the past 55 years, the investment management industry has evolved, with asset allocation becoming a prominent topic. The distinction between ownership and debt assets is crucial, with each offering different risk and return characteristics. The selection of […]
Researchers have developed a groundbreaking live imaging method that captures the process of ovulation in unprecedented detail, revealing three distinct phases: follicle expansion, contraction, and rupture leading to egg release. The study identified key factors driving ovulation, such as hyaluronic acid secretion, smooth muscle cell contraction controlled by progesterone and endothelin signaling, and molecular mechanisms […]
This article dives deep into the mechanics of amplifier feedback loops, focusing on op-amp circuits and the impact of adding capacitance in the feedback loop. The author breaks down complex concepts in an accessible way, highlighting the role of feedback in analog signal processing. Surprisingly, the addition of a feedback loop does not change the […]
Researcher Alon Leviev has discovered a way to downgrade Windows kernel components, allowing attackers to bypass security features like Driver Signature Enforcement and deploy rootkits on fully patched systems. Despite Microsoft’s dismissal of the issue, Leviev demonstrated at security conferences that this attack is feasible and remains unfixed. By using a tool called Windows Downdate, […]
Companies House forced a company to change its name after realizing it posed a security risk due to the use of HTML script tags. The company, now named “THAT COMPANY WHOSE NAME USED TO CONTAIN HTML SCRIPT TAGS LTD”, used a clever technique called “cross-site scripting” that could potentially allow an attacker to run code […]
This post provides an in-depth overview of SELinux, focusing on Android kernel exploitation. Tests were conducted on multiple devices, with a closer look at two devices with a hypervisor that complicates bypassing SELinux. SELinux, a Mandatory Access Control module, enforces a security policy at the Linux kernel level. The post delves into Linux Security Modules […]
XJDR’s Entropix project aims to enhance reasoning in AI models by improving sampling techniques during moments of uncertainty. While full-scale evaluations are pending, Entropix introduces intriguing methods and mental models for improving AI reasoning. The project focuses on adaptive sampling based on metrics like entropy and varentropy to determine the model’s confidence level and adjust […]
The OMNIPARSER tool enhances GPT-4V’s ability to accurately generate actions on user interfaces by parsing screenshots and identifying interactable icons and their semantics. A curated dataset of interactable icon detection is used to fine-tune models for this purpose, resulting in improved performance on various benchmarks. Interestingly, OMNIPARSER outperforms GPT-4V baselines even with screenshot-only input, showing […]
This paper demonstrates that Dijkstra’s shortest-path algorithm is universally optimal when used in conjunction with an efficient heap data structure, ensuring optimal performance for every graph topology. A new heap data structure with a working-set property is introduced, reducing the cost of extracting the minimum element to merely logarithmic in the number of inserted elements, […]
