French Modernists and the Mass Media: A Love-Hate Relationship

2025-01-17
French Modernists and the Mass Media: A Love-Hate Relationship

This essay explores the complex relationship between 19th-century French modernist writers and the mass media, particularly newspapers. From Baudelaire to Proust, they both loathed the negative impacts of newspapers (e.g., inciting crime, suppressing literature) and were deeply influenced by them, utilizing their platforms for creation and promotion. Newspapers served as both a crucible of modernity and a laboratory for literary innovation. Writers struggled against them while actively integrating them into their work; Mallarmé's groundbreaking poem *A Throw of the Dice* was published in the commercial magazine *Cosmopolis*. Ultimately, the author argues that in the face of the internet's information deluge, we can learn from the French modernists' experience, maintaining artistic independence while skillfully leveraging new media.

Failed Startups Leave Employees Vulnerable to Data Breaches via Google Logins

A security researcher discovered a critical vulnerability exposing employees of defunct startups to significant data breaches. By acquiring expired domains, attackers can exploit "Sign in with Google" to access company cloud software, potentially stealing Slack messages, Social Security numbers, and bank account details. While Google's OAuth configuration includes safeguards, improper implementation by some SaaS providers leaves the vulnerability exploitable. Tens of thousands of former employees and millions of SaaS accounts are at risk. Google has updated its documentation, advising companies to properly shut down cloud services, but the issue remains unresolved.

Cognitive Load: The Silent Killer in Software Development

2024-12-25

This article explores the importance of cognitive load in software development. Cognitive load refers to the amount of mental effort a developer needs to complete a task; high cognitive load leads to confusion, wasted time, and money. The article analyzes intrinsic and extraneous cognitive load, illustrating how to reduce extraneous load through code examples, such as using meaningful intermediate variables, avoiding nested if statements, and prioritizing composition over inheritance. It also stresses avoiding excessive microservices, choosing appropriate language features, and adhering to the Single Responsibility Principle, noting that excessive abstraction and layered architectures can increase cognitive load. Finally, the article advises developers to focus on code readability and collaborate with junior developers to identify and improve cognitive load issues.

Adding Refinement Types to Rust: A Feasibility Study

2024-12-24

This article explores the feasibility of adding refinement types to the Rust programming language. Drawing on experience with YAIOUOM, a static analyzer that used refinement types to check units of measure, the author examines approaches to implementing refinement types within Rust's type system. Several options are proposed, including modifications to trait resolution, type variable unification, and the introduction of a pluggable keyword mechanism for post-compilation type checking. An optimistic approach—ignoring unit information early in compilation and checking later—is deemed more practical. API design and error message handling are discussed. Future work involves gathering feedback, writing a rustc driver supporting plugins, and implementing several refinement types, potentially including a new version of YAIOUOM and subsets of Flux or Liquid Haskell.

Farewell to Endless Meetings: A New Approach to High-Velocity Software Development

2024-12-15

Tired of endless meetings and lengthy planning? This article introduces a high-efficiency software development method: code-centric, rapid iteration. The author uses baking as an example to illustrate the concept of achieving the optimal solution through rapid experimentation, frequent testing, and continuous improvement. This method emphasizes reducing documentation, expressing ideas directly in code, using mock data and hot-reloading tools to speed up development, and improving code readability through concise code style and naming conventions. The author advocates breaking down projects into independently executable files, minimizing restart time, and using default language tools for debugging. Although this method may seem like a "chaotic lab," it can efficiently complete projects and avoid the redundancy and inefficiency of traditional methods.

Slow Deployments Breed Meetings: A Reverse Causality Argument

Slow Deployments Breed Meetings: A Reverse Causality Argument

Programmers often complain about too many meetings hindering productivity. Kent Beck challenges this notion, suggesting that meetings are a consequence, not the cause, of slow deployments. Facebook's experience shows that increasing deployment frequency is key. When deployment speed lags behind code changes, organizations add meetings and reviews to mitigate risk, ultimately reducing efficiency. Instead of reducing meetings, focus on improving deployment capacity by shortening cycles or enhancing code quality. This essay offers a fresh perspective, exploring the counter-intuitive relationship between slow deployments and increased organizational overhead.

Stanford Report Warns of Mirror Bacteria Feasibility and Risks

Stanford Report Warns of Mirror Bacteria Feasibility and Risks

A Stanford University technical report details the feasibility of creating 'mirror bacteria' and their potential risks. Mirror bacteria, with all chiral molecules (proteins, nucleic acids, and metabolites) replaced by their mirror images, cannot evolve naturally but are becoming increasingly synthesizable. Immune systems and predation rely on chiral molecule interactions, meaning mirror bacteria could evade detection and control, potentially spreading unchecked and posing serious threats to humans, animals, plants, and the environment. The report comprehensively assesses synthesis, biosecurity, human health impacts, medical countermeasures, and ecological consequences, urging attention to this potential biosecurity risk.
