  Verbose tl;dr

  The post "JavaScript Views, the Hard Way" details a pattern for structuring JavaScript UI code using simple functions called "views." These views take data as input and return HTML strings as output, promoting separation of concerns between logic and presentation. The pattern emphasizes immutability by treating views as pure functions and managing state changes externally. It encourages composing complex UIs from smaller, reusable view functions, simplifying development and testing. While avoiding frameworks, this approach provides a structured way to organize UI code, making it more maintainable and predictable, especially for smaller projects where the overhead of a full framework might be unnecessary. The core concept involves rendering views based on data and updating the DOM only when the data changes, leading to a potentially more efficient rendering process.

  This GitHub repository, titled "JavaScript Views, the Hard Way," explores a specific pattern for structuring JavaScript user interface (UI) code, emphasizing explicit management of DOM elements and their associated data. Instead of relying on frameworks or libraries that abstract away DOM manipulation, this approach champions a more direct, granular level of control, potentially leading to improved performance in certain scenarios and offering a deeper understanding of how UI elements interact with JavaScript logic.

  The core idea revolves around creating distinct "view" objects. Each view object is responsible for a specific section of the DOM. It encapsulates the logic for creating, updating, and removing the associated DOM elements, as well as managing the data that those elements represent. This separation of concerns promotes code organization and maintainability, particularly in complex UI structures.

  Crucially, the pattern emphasizes avoiding direct manipulation of the DOM outside of the view object's methods. When data changes, the view object's update method is called, which efficiently reconciles the current state of the DOM with the new data. This targeted approach to DOM manipulation can minimize unnecessary reflows and repaints, leading to potential performance gains, especially in applications with frequent updates.

  The "hard way" moniker refers to the increased verbosity and manual effort involved in managing DOM elements directly. While frameworks often provide declarative ways to describe the UI and automatically handle updates, this pattern requires explicit coding of DOM operations. However, this explicitness can provide greater transparency and control over the UI's behavior and performance characteristics.

  The repository demonstrates this pattern with a practical example – building a simple to-do list application. This example illustrates how to create view objects for individual to-do items and how to manage the overall list structure using a parent view object. The code showcases techniques for efficiently updating the DOM when items are added, removed, or modified, highlighting the benefits of this more direct approach to UI development. By walking through this concrete example, the repository aims to provide a clear understanding of the pattern's principles and its potential advantages in specific situations where fine-grained control and performance optimization are paramount.

  Verbose tl;dr

  "Architecture Patterns with Python" introduces practical architectural patterns for structuring Python applications beyond simple scripts. It focuses on Domain-Driven Design (DDD) principles and demonstrates how to implement them alongside architectural patterns like dependency injection and the repository pattern to create well-organized, testable, and maintainable code. The book guides readers through building a realistic application, iteratively improving its architecture to handle increasing complexity and evolving requirements. It emphasizes using Python's strengths effectively while promoting best practices for software design, ultimately enabling developers to create robust and scalable applications.

  "Architecture Patterns with Python: Enabling Test-Driven Development, Domain-Driven Design, and Event-Driven Microservices" by Harry Percival and Bob Gregory serves as a comprehensive guide for structuring Python applications to achieve maintainability, testability, and scalability as they grow in complexity. The book meticulously details practical approaches for implementing clean architecture, domain-driven design (DDD), and event-driven architecture, emphasizing the crucial role of test-driven development (TDD) throughout the entire development lifecycle.

  The authors begin by establishing the importance of well-defined architecture and illustrating how neglecting this aspect can lead to tightly coupled, difficult-to-test, and ultimately unsustainable codebases. They advocate for a layered architecture that isolates business logic from external concerns such as databases, user interfaces, and third-party services. This separation of concerns enhances testability by allowing developers to test core application logic independently of these external dependencies.

  The book then delves into domain-driven design (DDD), a software development methodology that centers the design process around a deep understanding of the business domain. It emphasizes the importance of creating a ubiquitous language shared between developers and domain experts to facilitate clear communication and accurate modeling of the business domain within the software. Specific DDD tactical patterns, such as entities, value objects, aggregates, and repositories, are explained and demonstrated with practical Python examples.

  Furthermore, the authors address the challenges of scaling applications and introduce event-driven architecture as a powerful solution. They demonstrate how to design systems that communicate through asynchronous events, promoting loose coupling and enabling independent scaling of different parts of the application. The book covers different event-driven patterns and provides guidance on selecting the appropriate technology stack for implementing such systems in Python.

  Throughout the book, practical examples illustrate the architectural concepts using a real-world case study – an online order fulfillment system. This case study allows readers to see how the different architectural patterns are applied in a concrete context and evolve iteratively as the system's requirements change. The emphasis on test-driven development ensures that each architectural decision is validated by automated tests, providing confidence in the system's correctness and maintainability.

  In essence, "Architecture Patterns with Python" provides a practical roadmap for building robust, scalable, and maintainable Python applications by combining established architectural patterns with the principles of test-driven development and domain-driven design. It equips readers with the knowledge and tools to navigate the complexities of software architecture and build systems that can adapt to evolving business needs.

• Piranesi's Perspective Trick (2019)

  permalink

  Posted: 2025-03-27 11:41:30

  Verbose tl;dr

  Bruno Postle's "Piranesi's Perspective Trick" explores how 18th-century Italian artist Giovanni Battista Piranesi created the illusion of vast, impossible spaces in his etchings. Piranesi achieved this not through complex mathematical perspective but by subtly shifting the vanishing points and manipulating the scale of elements within a scene. By strategically placing smaller figures and architectural details in the foreground against exaggeratedly large background elements, and by employing multiple, inconsistent vanishing points, Piranesi generated a sense of immense depth and disorienting grandeur that transcends traditional perspective rules. This artistic sleight-of-hand contributes to the dreamlike and often unsettling atmosphere of his famous "Carceri" (Prisons) series and other works.

  Bruno Postle's 2019 Medium article, "Piranesi's Perspective Trick," delves into the intriguing methods employed by the 18th-century Italian artist Giovanni Battista Piranesi to create the illusion of immense and complex architectural spaces in his etchings, particularly within his series of imaginary prisons known as the Carceri d'invenzione. Postle meticulously dissects Piranesi's manipulation of perspective, arguing that Piranesi didn't merely employ standard one-point or two-point perspective, but rather a more complex and arguably flawed system that contributed to the disorienting and sublime atmosphere of the Carceri.

  The article's central thesis revolves around Piranesi's strategic placement of "inconsistent vanishing points." Rather than adhering to the rigid rules of traditional perspective where all lines converge on a single point or a set of consistent points, Piranesi introduced multiple and often contradictory vanishing points within a single image. This technique, Postle argues, creates a sense of spatial ambiguity and vastness, as the viewer's eye is constantly challenged to reconcile the conflicting perspectives. The effect is a feeling of being lost within a labyrinthine structure that extends far beyond the boundaries of the frame.

  Postle supports his analysis with detailed visual examples from the Carceri series. He highlights specific architectural elements like arches, staircases, and platforms, demonstrating how their lines converge on different and often irreconcilable points. He meticulously traces these lines, illustrating the inherent contradictions and demonstrating how they contribute to the overall impression of a vast, impossible space. The article goes beyond simply identifying these inconsistencies; it argues that these are not errors or oversights on Piranesi's part, but rather deliberate artistic choices intended to evoke a specific psychological and aesthetic response in the viewer.

  Furthermore, Postle connects Piranesi's unconventional perspective to the broader cultural context of the 18th century, linking it to the growing fascination with the sublime, an aesthetic category concerned with experiences of awe, vastness, and even terror. The unsettling spatial ambiguity of the Carceri, Postle suggests, is precisely what makes them so compelling and contributes to their sense of the sublime. The article thus positions Piranesi not just as a skilled draftsman, but as a sophisticated manipulator of visual language, using perspective not merely to represent space accurately, but to evoke a particular emotional and intellectual response.

  Posted: 2025-03-07 12:55:02

  Verbose tl;dr

  Researchers believe they may have discovered a network of tunnels beneath Milan's Sforza Castle, potentially matching sketches made by Leonardo da Vinci during his time as a court engineer there in the late 15th century. Using ground-penetrating radar and archive research, the team identified several underground passages and chambers consistent with da Vinci's drawings, suggesting he may have played a larger role in the castle's design and construction than previously thought. Further investigation is needed to confirm the tunnels' connection to da Vinci, but the discovery offers a tantalizing glimpse into the artist's diverse talents and the castle's complex history.

  In a remarkable discovery that bridges the gap between historical speculation and archaeological reality, researchers in Milan, Italy, believe they have potentially unearthed a network of subterranean passages initially documented by none other than the Renaissance polymath, Leonardo da Vinci. These tunnels, located beneath the venerable Sforza Castle, a prominent landmark with a rich and storied past, are thought to correspond with sketches and annotations found within da Vinci's copious notebooks, specifically the Codex Atlanticus. This monumental compilation of da Vinci’s thoughts, inventions, and observations provides tantalizing glimpses into his multifaceted genius, and the newly discovered tunnels offer a fascinating physical manifestation of his documented interest in the castle's infrastructure.

  The exploration of these subterranean corridors, undertaken by a team of dedicated specialists, revealed a complex and extensive network stretching beneath the castle grounds. While the original purpose of these tunnels remains a subject of ongoing investigation and scholarly debate, it is postulated that they served a multitude of functions, potentially including discreet passageways for prominent figures, strategic escape routes in times of conflict, and perhaps even conduits for the clandestine movement of supplies and personnel.

  The blog post "Common mistakes in architecture diagrams (2020)" identifies several pitfalls that make diagrams ineffective. These include using inconsistent notation and terminology, lacking clarity on the intended audience and purpose, including excessive detail that obscures the key message, neglecting important elements, and poor visual layout. The post emphasizes the importance of using the right level of abstraction for the intended audience, focusing on the key message the diagram needs to convey, and employing clear, consistent visuals. It advocates for treating diagrams as living documents that evolve with the architecture, and suggests focusing on the "why" behind architectural decisions to create more insightful and valuable diagrams.

  The blog post "Common Mistakes in Architecture Diagrams (2020)" from Ilograph emphasizes the importance of clear and effective communication in architectural diagrams, highlighting several common pitfalls that hinder comprehension and ultimately diminish their value. The post argues that while diagrams are crucial for conveying complex system designs, poorly constructed diagrams can be worse than having no diagrams at all, leading to confusion, misinterpretations, and ultimately hindering project success.

  The authors categorize these common mistakes into several key areas:

  1. Lack of Clarity and Purpose: The post stresses the necessity of a well-defined purpose for every diagram. Diagrams should answer specific questions and cater to a particular audience. Without a clear objective, diagrams risk becoming cluttered and confusing, failing to convey any meaningful information. This lack of clarity often manifests in ambiguous or missing labels, inconsistent use of shapes and colors, and a general lack of visual hierarchy.

  2. Excessive Detail: The post cautions against overwhelming the audience with unnecessary details. Including every single component or interaction can obscure the overall architecture and make the diagram difficult to understand. The authors advocate for a level of abstraction appropriate to the intended audience and the specific purpose of the diagram. This involves selectively choosing which elements to include and which to omit, focusing on the most relevant aspects of the system.

  3. Inconsistent Notation and Style: Consistency is paramount for readability. Using different shapes, colors, or line styles for the same type of component across different diagrams (or even within the same diagram) creates confusion and makes it harder to interpret the information. The post recommends establishing a clear visual language and adhering to it rigorously. This includes using a consistent legend or key to explain the meaning of different visual elements.

  4. Ignoring the Audience: The post highlights the importance of tailoring diagrams to the specific knowledge and needs of the target audience. A diagram designed for a technical audience will likely differ significantly from one intended for business stakeholders. Understanding the audience's familiarity with the system and their specific information needs is crucial for creating effective and relevant diagrams.

  5. Neglecting Aesthetics: While not the primary focus, the post acknowledges the importance of visual appeal. A well-designed diagram is not only easier to understand but also more engaging and persuasive. This involves paying attention to layout, spacing, color choices, and overall visual balance. A cluttered and visually unappealing diagram can detract from the message and make it less likely to be effectively communicated.

  6. Using the Wrong Diagram Type: Different types of diagrams are suited for different purposes. The post briefly touches upon the importance of choosing the right diagram type, whether it's a network diagram, a deployment diagram, a component diagram, or another type, to effectively convey the intended information. Using the wrong type of diagram can lead to misinterpretations and obscure the relevant aspects of the architecture.

  In conclusion, the Ilograph post emphasizes the crucial role of clear, concise, and well-designed architecture diagrams in successful software development. By avoiding these common mistakes, architects and developers can ensure that their diagrams effectively communicate complex system designs and facilitate better understanding among stakeholders.

  Posted: 2025-01-17 23:31:49

  Verbose tl;dr

  Researchers at the University of Stuttgart have developed a bioinspired adaptive shading system that responds to changing weather conditions without electricity. Mimicking the pine cone's humidity-driven scale movement, the system uses a bilayer material composed of wood veneer and a bacterial cellulose layer. When humidity increases, such as during rain, the cellulose swells, causing the shading elements to close. Conversely, in dry conditions, the cellulose shrinks, opening the elements and allowing light to pass through. This passive system offers a sustainable and energy-free solution for climate control in buildings, reducing the need for energy-intensive air conditioning and heating.

  Researchers at the University of Stuttgart's Institute for Building Structures and Structural Design (ITKE) have developed a bioinspired adaptive shading system for building facades, drawing inspiration from the pine cone's hygroscopic response to humidity. This innovative system, dubbed the "HygroSkin," utilizes a bilayer structure composed of wood veneer and a humidity-responsive polymer film. The wood veneer provides structural stability and aesthetic appeal, while the polymer film acts as the active component, expanding and contracting with changes in ambient humidity. This differential expansion and contraction between the two layers induces bending in the overall structure, mimicking the pine cone's scales opening and closing.

  In dry conditions, the polymer film shrinks, causing the HygroSkin elements to curl open, maximizing sunlight penetration into the building. Conversely, in humid conditions, the polymer film expands, causing the elements to close, effectively shading the building and reducing solar heat gain. This dynamic response to humidity provides a passive, energy-free mechanism for regulating indoor climate, reducing the need for energy-intensive heating and cooling systems. The system's passive nature eliminates the need for complex control systems or external power sources, making it a sustainable and cost-effective solution.

  The HygroSkin system's design is inherently scalable and adaptable, allowing for integration into various architectural contexts. The individual elements can be arranged in different configurations and densities to achieve desired shading performance. Furthermore, the system's use of natural materials aligns with principles of sustainable building design and contributes to a healthier indoor environment. The research team has rigorously tested the HygroSkin's performance through both laboratory experiments and computational simulations, demonstrating its effectiveness in modulating light transmission and solar heat gain. This biomimetic approach to building shading represents a significant advancement in sustainable architecture, offering a promising pathway towards creating more responsive and energy-efficient buildings that harmonize with the natural environment. The potential impact of this technology extends beyond simple shading, potentially influencing future developments in adaptive building envelopes and responsive architectural systems.

  Posted: 2025-01-16 18:08:16

  Verbose tl;dr

  From 1967 to 1988, under Enver Hoxha's paranoid communist regime, Albania constructed hundreds of thousands of concrete bunkers across its territory. Fearing invasion from both NATO and the Warsaw Pact, Hoxha envisioned these small, ubiquitous structures as defensive positions for a "people's war." While intended to protect against external threats, the bunkers ultimately proved largely useless for their intended purpose and now stand as a peculiar and enduring reminder of Albania's isolated past. They litter the landscape, repurposed for various uses or simply left abandoned, symbolizing the paranoia and misallocation of resources that characterized Hoxha's rule.

  During the reign of Enver Hoxha, the People's Socialist Republic of Albania embarked upon a program of unparalleled fortification, constructing an estimated 173,371 concrete bunkers across its relatively small territory. This extensive network of defensive structures, ranging from small pillboxes to elaborate underground complexes, was conceived as a deterrent against potential foreign invasions, reflecting Hoxha's isolationist policies and deep-seated paranoia regarding external threats. He envisioned a "bunkerized" nation capable of withstanding attacks from any conceivable adversary, including Yugoslavia, Greece, NATO, and even the Warsaw Pact, after Albania's withdrawal from the latter.

  The bunkers, which came to symbolize Hoxha's unwavering commitment to national defense and self-reliance, were strategically positioned throughout the country, dotting mountainsides, valleys, beaches, and even urban centers. Their ubiquitous presence profoundly impacted the Albanian landscape and the daily lives of its citizens, serving as a constant reminder of the perceived imminent danger. Construction, which spanned several decades, starting in the late 1960s and continuing until the early 1980s, involved significant resource allocation and manpower, diverting funds and labor from other essential sectors of the economy. Despite their intended purpose, the bunkers were never actually utilized in combat during Hoxha's lifetime.

  Following the fall of communism in Albania in 1990, these relics of the Cold War became a complex legacy. While viewed by some as symbols of oppression and a misallocation of national resources, others consider them a testament to the nation's resolve and ingenuity during a period of intense geopolitical uncertainty. The practical repurposing of these numerous structures has presented an ongoing challenge. Some have been converted into museums, cafes, or even accommodation, while others have been demolished or simply abandoned, slowly succumbing to the elements. The Albanian government has struggled with the costs and logistics of their removal, and the bunkers remain a visible and enduring feature of the Albanian landscape, serving as a tangible reminder of a unique chapter in the nation's history. Their very existence prompts continued reflection on Hoxha's legacy, the impact of Cold War anxieties, and the challenges of repurposing infrastructure born from a bygone era.

  Posted: 2024-12-18 13:19:27

  Verbose tl;dr

  Boston City Hall's Brutalist design emerged from a complex interplay of factors in the 1960s. Facing pressure to revitalize Scollay Square and embrace modernism, the city held an architectural competition. The winning design by Kallmann, McKinnell & Knowles, though initially controversial for its stark departure from traditional styles, aimed to embody democratic ideals with its open plaza and accessible interior. The project, part of a larger urban renewal effort, reflected the era's optimism about government's ability to solve social problems through architecture and urban planning. Despite its initial unpopularity, City Hall stands as a significant example of Brutalist architecture and a testament to the city's ambition for a modern future.

  Within the bustling metropolis of Boston, Massachusetts, the imposing Brutalist edifice known as City Hall stands as a stark testament to a pivotal era in the city's architectural and political history. Its genesis, a complex tapestry woven with threads of urban renewal, political maneuvering, and architectural ambition, is a narrative worthy of extensive elucidation. The mid-20th century witnessed a pervasive fervor for modernization sweeping across American cities, and Boston, steeped in its venerable past, found itself grappling with the exigencies of a rapidly evolving urban landscape. Slum clearance initiatives, often controversially implemented, sought to eradicate dilapidated neighborhoods, making way for ambitious redevelopment projects. This period of urban upheaval provided the fertile ground from which the concept of a new City Hall would ultimately germinate.

  The existing City Hall, a structure of dignified antiquity, was deemed inadequate for the burgeoning needs of a modern municipality. Its cramped confines and outdated infrastructure could no longer effectively accommodate the expanding bureaucracy and the increasingly complex demands of governance. Thus, the impetus for a new civic center, a symbol of Boston's forward-looking trajectory, began to gather momentum. A design competition, a hallmark of democratic processes and architectural innovation, was launched, attracting submissions from a multitude of architectural firms vying for the prestigious commission. The eventual victor, Kallmann McKinnell & Knowles, presented a design that boldly departed from the prevailing architectural norms of the time.

  Their proposal, a monumental structure of pre-cast concrete, embraced the Brutalist aesthetic, a style characterized by its raw, unadorned surfaces, massive forms, and exposed structural elements. This architectural choice proved to be highly divisive, sparking a maelstrom of public debate and critical commentary. Detractors lambasted the building's austere aesthetic, deeming it an affront to the city's historical character and a concrete behemoth ill-suited to the human scale. Proponents, however, lauded its audacious modernity, viewing it as a powerful expression of civic pride and a symbol of Boston's progressive spirit. The ensuing controversy, a clash between traditional sensibilities and the avant-garde, became emblematic of the broader societal tensions surrounding urban renewal and the evolving definition of architectural beauty.

  The construction of Boston City Hall, a protracted and costly undertaking, further exacerbated the existing divisions within the city. Disputes over budgets, construction delays, and the displacement of communities in the name of progress fueled the flames of discontent.

  Verbose tl;dr

  HN commenters discuss Boston City Hall's Brutalist architecture, mostly negatively. Several lament its ugliness and unfriendliness, comparing it to a parking garage or fortress. Some criticize its impracticality and lack of human scale, citing confusing navigation and wind tunnels. A few offer counterpoints, arguing that it's a significant example of Brutalist architecture, reflecting the era's optimism about government's role. One suggests its imposing design might have been intentional, meant to convey authority. The concrete's weathering and the surrounding plaza's design are also criticized. A couple of commenters express appreciation for the building's unique character, suggesting that its starkness has a certain appeal.

  The Hacker News post titled "How Boston City Hall was born," linking to a Boston Globe article about the building's history, has a modest number of comments, leading to a somewhat limited discussion. The comments do not offer dramatically different perspectives but rather expand on specific aspects touched upon in the article or offer related anecdotal information.

  One commenter focuses on the Brutalist architectural style of Boston City Hall, mentioning its divisive nature and how opinions on it haven't softened much over time. They also highlight the poor public reception of many Brutalist buildings, leading to their demolition in some cases, while noting Boston City Hall has managed to avoid this fate.

  Another commenter draws a parallel between the architectural style of Boston City Hall and similar concrete structures in the UK, suggesting a common aesthetic and possibly shared influences. They mention the prevalence of such buildings in British town centers and university campuses, hinting at a broader trend in that era.

  Building on the theme of public perception, a different commenter shares a personal anecdote about their father, an architect who worked on a Brutalist-style library. This commenter notes their father's eventual regret over the project, feeling it contributed negatively to the surrounding urban landscape. This personal story adds a human dimension to the discussion of Brutalist architecture and its impact on communities.

  A further comment pivots slightly to discuss the urban planning decisions of the time, linking them to the then-prevalent theories of architect Le Corbusier. The commenter suggests that the creation of plazas and the separation of pedestrian and vehicular traffic, as seen around City Hall, were influenced by Corbusier's ideas, although their execution might not have always been successful.

  Finally, a commenter provides some contextual information about the political and social climate of Boston in the 1960s, highlighting the influence of Mayor John Collins and his focus on modernizing the city. This adds a layer of historical understanding to the discussion, connecting the architectural choices to the broader political and social forces at play.

  While the discussion doesn't delve into highly technical or complex architectural critiques, it provides some interesting personal reflections, historical context, and observations about the broader trends in architecture and urban planning during that period. The comments, while limited in number, paint a picture of the ongoing debate surrounding Brutalist architecture and its place in the urban landscape.
