Ian's Secure Shoelace Knot
Ian's Secure Shoelace Knot, also known as the "Double Slip Knot," offers a reliable and symmetrical method for tying shoelaces that won't easily come undone. The knot is tied by creating two loops, crossing them, and passing them through a central hole, resulting in a tight, double-wrapped finish. This knot is particularly beneficial for those with round, slippery laces or for individuals engaged in active pursuits like sports or sailing. Testing shows it requires nearly twice the tension to untie compared to standard knots. A common issue with uneven knots is often due to tying an unbalanced "Granny Knot." For more details on achieving a neat finish, visit the Technical Info page.

Photo Editor for Cats
In this playful exploration of photo editing tools, the author delves into the new Style Edit feature on the iPhone 16, likening its intuitive 2D slider to a revolutionary UX advancement akin to the invention of the mouse. The tool, which combines a palette (essentially a look-up-table) with a 3-channel curves tool, offers a quick way to achieve a cohesive visual language. However, it's controversially restricted to the latest iPhone, prompting the author to consider creating a web version. The author shares their journey of building a 2D slider component, using CSS grids and mathematical calculations to create an interactive dot grid that responds to cursor movement. The clever use of HSL color values and scaling effects adds a layer of visual interest, though the author humorously notes the distraction it causes from their main goal of photo editing. The piece ends on a light note, with the author planning to continue their project after a break.

Hertz's Tesla Fire Sale Continues as Depreciation Costs Mount
Hertz's ambitious venture into electric vehicles (EVs) as rental cars has turned into a financial quagmire, with depreciation costs soaring by 89% to $537 per car monthly. The company is now in the midst of a massive sell-off, aiming to offload 30,000 EVs, including Tesla and Polestar models, by the end of 2024. This move comes after Tesla's unexpected price cuts, which drastically reduced the value of Hertz's fleet. Despite the initial promise of lower maintenance costs, Hertz's Teslas have incurred high repair expenses, exacerbated by frequent collisions. The situation highlights a significant challenge for the car rental industry in managing EV fleets, with Hertz's losses serving as a cautionary tale. However, for used car buyers, this presents an opportunity to purchase a Tesla Model 3 for under $20,000, potentially reduced further by a $4,000 federal tax credit. The controversy lies in the unforeseen financial pitfalls of Hertz's green initiative, raising questions about the future of EVs in the rental market.

Learning to use a handy Third Thumb may be easier than you think
The Third Thumb, a 3D-printed prosthetic designed by Danielle Clode, has shown surprising ease of use, as demonstrated in a recent University of Cambridge study. Originally a graduate project, the Thumb is controlled by toe pressure and can be mastered in just one minute by most users, regardless of age or handedness. This study, involving 596 participants at the Royal Society Summer Science Exhibition, revealed that nearly all could move the Thumb purposefully, and many could manipulate objects with it. The device's potential extends beyond enhancing manual dexterity for able-bodied individuals to aiding those with reduced dexterity. Clode emphasizes the importance of inclusive design in wearable technology, aiming for these devices to become extensions of the body. The study's findings were published in Science Robotics. The ease of learning and broad applicability of the Third Thumb is both surprising and promising for future technological integration with the human body.

A basic introduction to the classfile API in Java
In this article, we explore the class file API, a new feature in Java defined by JEP 484, which provides a standardized way to parse, generate, and transform Java class files. Although still in preview and set to be finalized with JDK 24, this API offers an alternative to ASM, albeit with less available documentation. The article provides a basic introduction to creating class files by converting a simple Java program into JVM bytecode. The author emphasizes that this is not an in-depth guide, as the code examples were derived from examining bytecode using javap and mapping it to the API. The article highlights the JVM's stack-based nature and contrasts it with register-based machines. A unique aspect is the use of preview features, such as the instance main method, which simplifies the traditional public static void main syntax. The author also discusses the use of ClassDesc and ConstantDescs to manage class and field descriptors, making the process more streamlined. The article is candid about its limitations, serving as a gentle introduction rather than a comprehensive tutorial. (Summary based on 40% of story text.)

The Structure of a Worldview
In "The Structure of a Worldview," the author delves into the complex formation and influence of worldviews, drawing parallels with personality structures like the Big Five. Inspired by thinkers like Robin Hanson and Thomas Sowell, the essay explores how worldviews shape political and moral disagreements. The author questions whether a single axis, such as progressivism vs. conservatism, can explain worldview differences or if multiple independent factors are needed. A notable controversy arises from the critique of postmodernism, which challenges the notion of objective truth and power dynamics.
