The author discusses their experience with a security module assignment involving a barebones virtual machine (VM). The VM requires updates to be installed to complete assignments and obtain tokens for submission, but the update files are encrypted and appear as unreadable data. The author suspects that the update files contain the needed tokens and decides to investigate the decryption process. They examine the `installUpdate` executable in the VM, discovering that the updates are GPG encrypted tarballs. The executable references a file containing a pass

The Universal Postal Union (UPU), a UN agency, has established the S10 standard for tracking postal items, which defines a 13-character format used globally for parcel tracking numbers. A recent experience receiving a parcel from Switzerland highlighted that the format of the tracking number (UT038926726CH) aligns closely with the UK's tracking system. This prompted curiosity about the compatibility between different postal services. The S10 standard assigns each country's postal service exclusive rights to generate S10 codes, incorporating details about the

Trevor I. Lasn, a Staff Software Engineer and Engineering Manager, reflects on his exploration of code from 2006-2015. Instead of finding outdated practices, he is impressed by the innovative solutions early web frameworks provided. During this period, web development had to tackle browser inconsistencies, particularly with Internet Explorer 6 dominating the market. The launch of jQuery 1.0 in August 2006 greatly simplified DOM manipulation by creating a consistent API that abstracted browser differences. Designed

The author describes their process of creating a minimal decorator from scratch to add view-related methods to a Teacher object, due to incompatibility with the draper gem in their older Rails application. They aim to implement a `colour_coded_availability` method that generates CSS classes for a table of teachers based on their availability. To accomplish this, the author creates a decorator that accepts a Teacher instance and exposes the `colour_coded_availability` method. However, they encounter a `NoMethodError`

The authors of the study, led by Parshin Shojaee and Iman Mirzadeh, explore the capabilities and limitations of Large Reasoning Models (LRMs) that generate detailed reasoning processes before answering questions. While LRMs show improved performance on reasoning tasks, their scaling properties and fundamental abilities are not fully understood. Current evaluations focus on final answer accuracy, often overlooking the structure and quality of the reasoning traces. The researchers used controllable puzzle environments to assess both final answers and internal reasoning processes

The author discusses their transition from using 1Password to generate one-time passwords (OTP) for publishing to RubyGems, primarily due to dissatisfaction with subscription models and the want to eliminate Electron apps. They outline a method for generating OTPs using touch ID or the system password on macOS, noting that other systems, such as YubiKey, may provide alternatives for non-macOS users. The setup process involves generating a password for the `totp-cli` in Apple's Password.app,

The author, unable to afford the $3,500 Apple Vision Pro, created a similar eye-tracking project called Eyesite. Using the WebGazer.js library, they implemented eye tracking with calibration for improved accuracy. The idea was to allow users to interact with a website using their gaze instead of a mouse, and clicking would be done with the spacebar, mimicking the Apple Vision Pro's functionality. Initially, a visible red dot indicated where users were looking, but this distracted users and revealed

The author reflects on their journey, transitioning from focusing on product development to enhancing developer productivity. They emphasize the importance of saving small amounts of time for developers, which can lead to significant overall efficiency gains. A pivotal project in their career was the Office migration from Source Depot to Git, which highlights the evolution of version control systems. In the early 2000s, Microsoft's source control landscape was challenging, as Git was not yet available, and other options like SVN were still emerging. Microsoft created its own

The European Space Agency's Solar Orbiter spacecraft has successfully tilted its orbit around the Sun, allowing it to capture the first images of the Sun’s poles from outside the ecliptic plane. This new perspective is expected to enhance our understanding of the Sun’s magnetic field, solar cycles, and space weather. Traditionally, Sun images have been taken from the ecliptic plane, primarily focusing on its equator. On March 23, 2025, Solar Orbiter viewed the Sun at an angle

The article discusses the Raku programming language and its metamodel, addressing the perception of Raku as having a large, complex core. It references John McCarthy's perspective on mathematical neatness influencing language design and responds to a comment on Reddit advocating for languages with a "small, orthogonal core." The author aims to demonstrate that Raku does, indeed, have a tidy core. The discussion is structured into seven sections: 1. An overview of Raku's CORE, which includes functions and

In a recent paper published in *Physical Review D*, researchers propose an alternative theory to the Big Bang, suggesting that the universe may have emerged from a colossal black hole's gravitational collapse followed by a "bounce." This theory, termed the "black hole universe," challenges the conventional understanding of cosmic origins, which typically start with the Big Bang as a singular event. While the current cosmological model has effectively explained the universe's structure and evolution, it is based on concepts like cosmic inflation and dark energy that
