  Verbose tl;dr

  The <command> and <commandfor> elements, now supported in Chrome 165, offer a declarative way to define commands and associate them with specific form controls. <command> represents a user action, like "copy" or "bold," and can be executed via various input methods (keyboard shortcuts, context menus, buttons). <commandfor> links a command to a specific HTML element, like a text input, clarifying which element the command operates on. This allows assistive technologies and other user agents to better understand the available actions and their targets, improving accessibility and user experience. This declarative approach simplifies command handling, especially for custom controls, and reduces reliance on JavaScript for basic command functionality.

  This Chromium Developers blog post introduces two new HTML elements, <command> and <commandfor>, designed to enhance the declaration and association of commands within web applications, particularly focusing on improving accessibility and platform integration. The post elaborates on the motivation behind these additions, explaining that existing mechanisms for handling commands, such as using <button> or <input type="button">, lacked semantic clarity concerning their role as commands and offered limited means of linking a command to its specific target element. Furthermore, the reliance on JavaScript event handlers for command execution posed challenges for accessibility tools and platform integrations, as the intent of the element wasn't explicitly conveyed in the HTML.

  <command> serves as a declarative representation of a command within a web page. It doesn't render visibly by default but can be styled for visual representation if desired. The element encompasses various attributes that define the command's properties, including its label for textual representation, its icon for visual representation, its associated shortcut keys, and a crucial disabled attribute for controlling its availability. The post details how these attributes contribute to a more robust and semantically rich description of a command. It illustrates how <command> encapsulates the nature and state of the command itself, independent of how it is triggered.

  Complementing <command>, the <commandfor> element explicitly connects a defined command to a specific HTML element. This association enhances accessibility by providing a clear link between the command and its target, enabling assistive technologies to understand and convey this relationship to users. The for attribute within <commandfor> points to the ID of the target element, creating this essential connection. The blog post demonstrates through examples how using <commandfor> improves the discoverability and usability of commands within a web page, particularly for users relying on assistive technologies.

  The post highlights the benefits of using <command> and <commandfor> for improved keyboard navigation, accessibility, and integration with platform features like context menus. By declaring commands and their targets directly in HTML, developers enable richer interactions with assistive technologies, allowing users to discover, understand, and execute commands more effectively. Furthermore, it streamlines the process of adding keyboard shortcuts and facilitates platform-specific integrations, such as context menu additions, without relying solely on complex JavaScript event handling. The post concludes by encouraging developers to explore these new elements and provide feedback to help shape their further development and standardization.

  Posted: 2025-02-24 04:38:03

  Verbose tl;dr

  This 2018 paper demonstrates how common spreadsheet software can be used to simulate neural networks, offering a readily accessible and interactive educational tool. It details the implementation of a multilayer perceptron (MLP) within a spreadsheet, using built-in functions to perform calculations for forward propagation, backpropagation, and gradient descent. The authors argue that this approach allows for a deeper understanding of neural network mechanics due to its transparent and step-by-step nature, which can be particularly beneficial for teaching purposes. They provide examples of classification and regression tasks, showcasing the spreadsheet's capability to handle different activation functions and datasets. The paper concludes that spreadsheet-based simulations, while not suitable for large-scale applications, offer a valuable pedagogical alternative for introducing and exploring fundamental neural network concepts.

  The arXiv preprint "Computer Simulation of Neural Networks Using Spreadsheets (2018)" by Corey J. Noxon details a method for constructing and simulating artificial neural networks entirely within a spreadsheet program like Microsoft Excel or Google Sheets. The author argues that this approach provides several pedagogical advantages, particularly for introductory courses in artificial intelligence, machine learning, or computational neuroscience. Spreadsheet software is readily available, requires no specialized programming knowledge, and offers an interactive environment that allows students to directly manipulate and visualize the network’s components and observe their effects on the computation.

  Noxon’s method leverages the inherent computational capabilities of spreadsheets to implement the fundamental building blocks of a neural network. He meticulously describes how to represent neurons with their activation functions (specifically, the sigmoid function is used as the primary example), weighted connections between neurons, and the process of forward propagation to calculate the network’s output given a set of inputs. The implementation uses spreadsheet formulas to calculate weighted sums of inputs, apply the activation function, and propagate signals through the network layers. This allows students to explicitly see the calculations involved at each step, fostering a deeper understanding of the underlying mathematical principles.

  The paper demonstrates the construction of a simple feedforward neural network with an input layer, a hidden layer, and an output layer. The author provides detailed instructions and example formulas for setting up the network architecture within the spreadsheet. He also discusses how to present input data to the network and interpret the resulting output. While the example focuses on a relatively small network, the principles described can be extended to build more complex architectures.

  Furthermore, the paper touches upon the concept of training the network. While a full implementation of backpropagation and gradient descent is not detailed within the spreadsheet framework, the author discusses the basic principles of adjusting weights to improve the network's performance. He suggests that the spreadsheet model can be used to illustrate the effect of weight changes on the output, providing a conceptual foundation for understanding the learning process in neural networks.

  The primary contribution of this work is not to propose a novel or efficient method for large-scale neural network simulation. Instead, it offers a readily accessible and interactive tool for educational purposes. By using familiar spreadsheet software, the author aims to demystify the seemingly complex world of neural networks and make their underlying principles more understandable to a wider audience, especially those without extensive programming experience. This approach empowers students to experiment with different network configurations, inputs, and weights, gaining valuable hands-on experience and developing an intuitive understanding of neural network behavior. The paper concludes by emphasizing the potential of this method to enhance the learning experience in various educational settings.

  "What if Eye...?" explores the potential of integrating AI with the human visual system. The MIT Media Lab's Eye group is developing wearable AI systems that enhance and augment our vision, effectively creating "eyes for the mind." These systems aim to provide real-time information and insights overlaid onto our natural field of view, potentially revolutionizing how we interact with the world. Applications range from assisting individuals with visual impairments to enhancing everyday experiences by providing contextual information about our surroundings and facilitating seamless interaction with digital interfaces.

  The Massachusetts Institute of Technology's "Eye..." project, accessible at eyes.mit.edu, poses a profound and multifaceted inquiry into the evolving relationship between human perception and artificial intelligence. The project, presented as a website, invites contemplation on the potential implications, both utopian and dystopian, of imbuing inanimate objects with the capacity for visual processing. Specifically, it explores the hypothetical scenario where everyday items, from the mundane to the extraordinary, are granted the ability to “see,” thereby transforming their function and interaction with the world.

  The central conceit revolves around imbuing these objects with diverse forms of artificial vision, ranging from rudimentary light detection to sophisticated image recognition and analysis. The project encourages viewers to consider the transformative impact this newfound perception could have on the objects themselves and, more broadly, on human society. What new functionalities might emerge? How would these objects’ behavior change? Would they become more autonomous, more responsive, or perhaps even more aware of their surroundings?

  The website leverages a visually compelling interface to showcase a collection of hypothetical "Eye..." scenarios. Each scenario depicts a common object, such as a chair, a door, or a plant, augmented with a stylized representation of an "eye." These visual representations serve as a symbolic portal, prompting reflection on the potential implications of granting vision to these otherwise inanimate entities. By presenting these evocative images and accompanying thought-provoking questions, the project seeks to stimulate discussion and debate surrounding the ethical, societal, and philosophical dimensions of increasingly pervasive artificial intelligence. The "Eye..." project, therefore, is not merely a technological exploration, but rather a nuanced examination of the intricate interplay between technology, perception, and the human experience. It serves as a platform for engaging with the complex questions that arise when the boundaries between the seeing and the seen become increasingly blurred by advancements in artificial intelligence.

  Verbose tl;dr

  A recent study reveals that CAPTCHAs are essentially a profitable tracking system disguised as a security measure. While ostensibly designed to differentiate bots from humans, CAPTCHAs allow companies like Google to collect vast amounts of user data for targeted advertising and other purposes. This system has cost users a staggering amount of time—an estimated 819 billion hours globally—and has generated nearly $1 trillion in revenue, primarily for Google. The study argues that the actual security benefits of CAPTCHAs are minimal compared to the immense profits generated from the user data they collect. This raises concerns about the balance between online security and user privacy, suggesting CAPTCHAs function more as a data harvesting tool than an effective bot deterrent.

  A recent article published by PC Gamer, titled "CAPTCHAs: 'a tracking cookie farm for profit masquerading as a security service'," discusses a 2023 study that sheds light on the potentially exploitative nature of CAPTCHA systems. The study, referenced in the article, posits that CAPTCHAs, ostensibly designed to differentiate between humans and bots online, are being utilized as a mechanism for extensive user tracking and data collection, generating substantial profits for companies like Google while simultaneously costing users significant time and effort.

  The article elaborates on this claim by suggesting that the information gathered through CAPTCHA interactions, far exceeding the simple verification of human identity, is being leveraged to create detailed user profiles, potentially encompassing browsing habits, device information, and other sensitive data points. This wealth of user data is then purportedly monetized, effectively turning CAPTCHA systems into a vast "tracking cookie farm." The article emphasizes that this data collection occurs under the guise of security, with users led to believe they are contributing to a safer online environment while unknowingly becoming the product themselves.

  The PC Gamer piece further highlights the staggering cumulative time cost imposed on users by these ubiquitous security checks. Citing the study's findings, the article states that users have collectively spent approximately 819 billion hours completing CAPTCHAs, a figure that underscores the sheer pervasiveness of these systems and their impact on user experience. This immense time investment, the article argues, is being directly translated into substantial financial gains, with the study estimating that nearly USD 1 trillion has been generated for Google through CAPTCHA usage.

  The article thus paints a picture of CAPTCHA systems not as a benevolent security measure, but rather as a sophisticated data harvesting operation that exploits user time and trust for financial profit. The study's findings, as presented by the article, suggest that the current implementation of CAPTCHAs serves a dual purpose: ostensibly protecting websites from bot activity, while simultaneously enriching companies like Google through extensive user data collection. The article ultimately questions the ethical implications of this practice and the true cost of the widespread adoption of CAPTCHA technology.

  Verbose tl;dr

  Cloudflare is reportedly blocking access to certain websites for users of Pale Moon and other less common browsers like Basilisk and Otter Browser. The issue seems to stem from Cloudflare's bot detection system incorrectly identifying these browsers as bots due to their unusual User-Agent strings. This leads to users being presented with a CAPTCHA challenge, which, in some cases, is unpassable, effectively denying access. The author of the post, a Pale Moon user, expresses frustration with this situation, especially since Cloudflare offers no apparent mechanism to report or resolve the issue for affected users of niche browsers.

  A Hacker News user has reported that Cloudflare is seemingly blocking access to websites protected by its services when using the Pale Moon web browser, and potentially other less common browsers. The user describes encountering Cloudflare's "Checking your browser before accessing..." page, which typically precedes legitimate access but in this case never progresses, effectively denying access. This issue specifically arises with Pale Moon 29.4.1 (x64) on Windows 10. The user emphasizes that they have disabled all extensions and add-ons within Pale Moon, eliminating them as a potential cause of the blockage. They also note that clearing cookies and site data did not resolve the issue. The affected websites are served through Cloudflare, but the exact trigger for the block remains unclear. The user hypothesizes that Cloudflare might be targeting Pale Moon's User-Agent string, a piece of information browsers send to websites identifying themselves, speculating that Cloudflare may have a list of acceptable User-Agent strings and is blocking access from browsers with unrecognized identifiers. This suggests a potential incompatibility between Cloudflare's security measures and Pale Moon's browser identification. The user highlights the inconvenience this poses, particularly for users who rely on or prefer less mainstream browsers. The post implies a concern regarding the control Cloudflare exerts over web access and the potential for exclusion of legitimate users based on browser choice.

  Posted: 2025-02-01 21:12:37

  Verbose tl;dr

  This blog post presents a simple bookmarklet designed to remove fixed position headers on websites. The author, frustrated by obstructive sticky headers, created a JavaScript snippet that can be saved as a bookmark. When clicked, this bookmarklet iterates through all elements on the current page, identifies those with a fixed position (typically headers), and sets their position to static, effectively removing the sticky behavior. The post highlights the bookmarklet's effectiveness in reclaiming screen real estate and improving the browsing experience. It also includes the code snippet for easy copying and implementation.

  In a 2013 blog post titled "A bookmarklet to kill sticky headers," author Alasdair McDiarmid presents a JavaScript bookmarklet designed to remove fixed or "sticky" headers from web pages. He explains that while these headers can be useful in some contexts, they often obstruct content and become an annoyance, particularly on smaller screens where vertical real estate is precious. He identifies the primary CSS property responsible for this behavior as position: fixed; applied to the header element.

  McDiarmid provides the full JavaScript code for the bookmarklet, which iterates through all elements on the page. For each element, it checks if the position style is set to fixed. If it is, the script changes the element's position to absolute, effectively removing the fixed positioning and allowing the header to scroll with the rest of the page content. He emphasizes the simplicity and effectiveness of this approach, noting it doesn't require complex parsing or manipulation of the page's stylesheets.

  The author further explains how to create and use a bookmarklet: copying the provided JavaScript code and creating a new bookmark in the browser with the code pasted in as the URL. Clicking this bookmark on any webpage will then execute the script, modifying the fixed headers as described. He acknowledges the potential for unintended consequences, admitting that the script might affect elements other than headers that use position: fixed. However, he suggests the benefits of quickly disabling sticky headers generally outweigh this risk. The post concludes with the complete bookmarklet code, ready to be copied and used by readers.

  Motion Sickness Accessibility in Video Games

  permalink

  Posted: 2025-01-31 15:20:31

  Verbose tl;dr

  This blog post explores how video games can induce motion sickness and offers developers practical advice for mitigating it. The author explains how conflicting sensory information between visual motion and the vestibular system creates motion sickness, highlighting common culprits like field of view, camera acceleration, and head bob. The post advocates for robust accessibility options, suggesting features such as adjustable FOV, camera smoothing, disabling head bob, and providing comfort settings presets. By incorporating these considerations, developers can create more inclusive gaming experiences for players susceptible to motion sickness.

  In a comprehensive blog post entitled "Motion Sickness Accessibility in Video Games," author Madeline Miller delves into the multifaceted issue of motion sickness triggered by video games, exploring its causes, impact, and, most importantly, potential solutions for developers seeking to create more inclusive gaming experiences. Miller begins by meticulously defining motion sickness, characterizing it as a debilitating condition arising from a sensory conflict between the perceived motion conveyed by the visual system and the actual motion registered by the vestibular system, the body's internal balance mechanism. This disconnect, she explains, can lead to a constellation of unpleasant symptoms, ranging from mild nausea and disorientation to severe headaches and vomiting, effectively barring affected individuals from enjoying certain games.

  The author then proceeds to dissect the specific game design elements that frequently contribute to this sensory mismatch and the subsequent onset of motion sickness. She highlights factors such as excessive field of view (FOV), rapid camera movements, including abrupt acceleration, deceleration, and rotation, and the presence of head bob, a visual effect simulating the up-and-down motion of a character's head while walking or running. Further exacerbating the issue, she notes, are low frame rates and visually complex or cluttered environments that overstimulate the visual system.

  Having established the underlying mechanisms and triggers of motion sickness, Miller transitions to a detailed examination of potential mitigation strategies within game development. She advocates for a multi-pronged approach, emphasizing the importance of offering players a robust suite of customizable options to tailor the gameplay experience to their individual sensitivities. These options, she suggests, could include adjustable FOV settings, toggles for head bob and motion blur effects, and selectable camera behavior presets, ranging from less dynamic to more traditional settings. Furthermore, Miller champions the inclusion of "comfort modes" that prioritize minimizing motion sickness triggers, potentially incorporating features like static camera positioning or reduced character movement speeds.

  Beyond these specific technical interventions, the author emphasizes the significance of clear and upfront communication with players. She recommends that developers explicitly acknowledge the potential for motion sickness within their games and proactively inform players about available accessibility features. This transparency, she argues, empowers players to make informed decisions about their gameplay experience and fosters a more inclusive gaming environment.

  In closing, Miller reiterates the importance of prioritizing accessibility in game development, framing it not merely as a technical challenge, but as a crucial step towards ensuring that video games are enjoyable and accessible to everyone, regardless of their susceptibility to motion sickness. She encourages developers to adopt a proactive and empathetic approach to addressing this issue, recognizing the significant impact these seemingly small design choices can have on a player's ability to fully engage with and appreciate the interactive worlds they create.
