The Internet of Agents: Building the Future of AI Collaboration

Agentic AI is rapidly evolving, but the lack of shared protocols for communication, tool use, memory, and trust keeps systems siloed. To unlock their full potential, we need an open, interoperable stack – an Internet of Agents. This article explores key architectural dimensions for building this network, including standardized tool interfaces, agent-to-agent communication protocols, authentication and trust mechanisms, memory and context sharing, knowledge exchange and inference APIs, economic transaction frameworks, governance and policy compliance, and agent discovery and capability matching. The author argues that shared abstractions are crucial to avoid fragmentation and enable scalable, composable autonomous systems.

The Right to Root: Why You Should Own Your Devices

2025-01-13

This article argues for a "right to root" – the consumer's right to install and modify software on any computing device they own outright, regardless of form factor. The author contends that manufacturers' restrictions, justified by security concerns, are anti-consumer, stifle competition, and lead to shorter device lifespans and limited repair options. Using Apple devices as a prime example (comparing the open nature of MacBooks to the closed nature of iPads), the article discusses potential legal solutions and emphasizes that manufacturers should bear the burden of proving the necessity of hardware locks, except in cases like critical medical devices.

Isomorphic Web Components: Server-Side Rendering Made Easy

The long-held belief that server-side rendering of web components is difficult has been challenged. This article demonstrates how to achieve server-side rendering of existing web components by cleverly using Happy DOM to emulate a browser environment. Two methods are detailed: using the `` tag for direct rendering and emulating the DOM to run component code and generate HTML. The author emphasizes the advantages of this approach: compatibility with all web components, robustness in the face of JavaScript failure, and avoidance of framework lock-in. This solves the server-side rendering problem for web components, offering a flexible and resilient solution.

Generative AI's Ghost in the Machine: Copilot Leaks Private GitHub Repos

Israeli cybersecurity firm Lasso discovered that even briefly public GitHub repositories can be cached long-term by generative AI chatbots like Microsoft Copilot. Over 20,000 once-public repositories from major companies including Microsoft, Amazon, and Google are affected. Even after being set to private, Copilot can access their contents via Bing's caching mechanism, exposing sensitive data such as keys and tokens. Lasso notified affected companies, but Microsoft initially classified the issue as "low severity." While Microsoft disabled Bing cache links, Copilot still retains access, highlighting significant data security risks in generative AI.

Secret Passages Unearthed Beneath Milan's Sforza Castle: A Da Vinci Connection?

Scientists have discovered a hidden network of underground passages beneath Milan's Sforza Castle using non-destructive methods like ground-penetrating radar and laser scanning. The tunnels, hinted at in a Leonardo da Vinci sketch from around 1495 and historical records, likely served as escape routes or defense mechanisms for soldiers. This discovery underscores Da Vinci's military engineering prowess and highlights the importance of preserving cultural heritage. Further investigation revealed additional tunnels and underground chambers, one possibly leading to the Basilica of Santa Maria delle Grazie, potentially built by the Duke of Milan to access his late wife's tomb. Despite significant historical damage, the castle's subsurface structures retain a wealth of historical information, reminding us that history is often hidden in plain sight.

Iterated Log Coding: A Novel Floating-Point Encoding Format

2025-02-26

This article introduces a novel real number encoding format—iterated log coding. Unlike traditional floating-point representations, this format uses a sequence of sign bits to represent numbers, each sign bit indicating the positivity or negativity of the number within a specific range. This approach allows for a remarkably wide range of representable numbers, including extremely large or small values that are beyond the capabilities of traditional floating-point formats. It features a unique lexicographic ordering property. While the precision distribution is non-uniform, the method offers advantages in representing numbers within certain ranges, particularly where extremely large or small values are involved and precision requirements are less stringent.

Apple's 'Liquid Glass' UI Redesign: Form Over Function?

Apple's 'Liquid Glass' UI Redesign: Form Over Function?

Apple's new user interface design, "Liquid Glass," has sparked controversy. The author dissects Apple's developer documentation, revealing inconsistencies. The guidelines advocate blurring the lines between content and navigation while simultaneously advising clear separation. Unnecessary whitespace reduces screen density, and overly simplistic icon design requirements lead to bland, indistinguishable icons. The author argues that Apple prioritizes form over function, sacrificing user experience and developer freedom, resulting in homogenized third-party app icons. The focus on a "liquid glass" effect overshadows the importance of the elements it distorts.

A Programmer's Lesson: Always Bundle a Proposal with a Complaint

In 1988 at Apple, a young, cocky engineer, Kent Beck, was summoned to Jean-Louis Gassée's office after sending an email complaining about a company decision. Instead of anger, Gassée challenged Beck to consider his perspective and rewrite the email as a proposal for a solution. This experience taught Beck three valuable lessons: most problems aren't as big as they seem; always include a solution with a complaint; and effective communication requires empathy. This anecdote highlights crucial workplace communication skills and the importance of understanding different viewpoints.

Web Server Listen Overflows Traced to a Linux Kernel Performance Issue

2025-02-14

Upgrading web servers from CentOS to Ubuntu led to listen overflow errors. Investigation revealed a system CPU spike on newly booted Ubuntu hosts within minutes of startup, causing slow web request processing and subsequent listen overflows. The culprit was inode cgroup switching in the Linux kernel; after writing many files, the kernel spent significant time moving inodes between cgroups. Disabling the io or memory controllers in systemd resolved the issue. CentOS was unaffected as it uses cgroups v1, unlike Ubuntu's cgroups v2. A minimal reproduction script was created to demonstrate the issue.

In Defense of Text Labels: Why Icons Aren't Enough

This article argues for the importance of text labels alongside icons in user interface design. The author contends that relying solely on icons increases cognitive load, as many icons lack immediate clarity and require extra interpretation, especially in complex interfaces with numerous icons. Text labels efficiently clarify meaning, reducing ambiguity and improving usability. The article also highlights inconsistencies in iconography across different applications, adding to user confusion. Therefore, the author advocates for a combined approach, using both icons and text labels for optimal user experience.
