As Lewis and Clark's Corps of Discovery journeyed to Oregon, they were mostly unconcerned with documenting their history. However, they faced significant digestive issues due to a low-fiber diet, resulting in everyone becoming constipated. To address this, the group traveled with 600 "thunder-clapper" pills, made primarily of mercury salt, which they regularly used to alleviate their symptoms. Interestingly, this reliance on mercury pills has aided archaeologists in locating several of their campsites, as

Sideloading, or the ability to install applications outside official app stores, has become a contentious issue, particularly with Google's recent restrictions on Android. A common argument is that users should be able to run any code on their own hardware. While this is a valid point, the discussion often misses a key distinction: Google's restrictions are about controlling the software environment rather than the hardware itself. Furthermore, users often do not have full access to the underlying hardware, complicating the development of custom operating systems for

CVE-2025-7783 is a recent vulnerability affecting many applications in the Node.js ecosystem, notably those utilizing the axios library or the deprecated request library. The exploitation of this vulnerability is considered unlikely as it depends on the attacker gaining access to five consecutive outputs of JavaScript's Math.random(), allowing them to predict future outputs using the z3 solver. The author, a former cryptographer, questioned the efficacy of z3 for inverting the Math.random() generator and aimed to develop a

The author discusses a recent on-premises deployment of their SaaS for a security-conscious fintech client, highlighting a challenge they faced: creating a comprehensive list of all outbound API calls made by their application. While they had standard deployment scripts, they had not tracked outbound calls due to their own infrastructure's lack of restrictions. The client required strict compliance with their firewall policy, necessitating a detailed whitelist of API endpoints. Initially, the team underestimated the complexity, assuming they could manually identify the calls. However,

Millions of Android users are affected by Google's decision to restrict the installation of APKs, impacting students, workers, gamers, independent developers, and those in regions with limited Play Store access. This change undermines Android's key advantage over iOS: the freedom to install alternative apps, emulators, and other software not available on the official store. If implemented, Android may become more restrictive, reducing innovation and user choice while increasing centralized control over app availability. While Google aims to protect users from malware,

The author expresses a complicated relationship with NumPy, a popular Python library for numerical computations on arrays that has heavily influenced machine learning libraries. While NumPy simplifies straightforward tasks, it becomes challenging with more complex problems involving large stacks of matrices and vectors, as it's difficult to find appropriate methods when avoiding loops, which are slow. Although NumPy can leverage GPU functions for better performance, the documentation is unclear, leaving users unsure about how to execute certain vector-matrix operations efficiently. The author suggests that many users
