FASTIFY + REACT IS 7X FASTER THAN NEXT.JS

A recent benchmark comparing server-side rendering performance found that @fastify/react is 7x faster than Next.js, handling 347 requests per second versus Next's 49. The test used minimal setups, showing that Fastify-based integrations like @fastify/vue and @fastify/react are leaner and faster than full-featured metaframeworks.

AMP AND WHY EMAILS ARE NOT (AND SHOULD NEVER BE) INTERACTIVE

Google's AMP for email tried to modernize email by adding interactive features, similar to its earlier AMP project for mobile web pages. AMP for email required significant effort to implement and support, only worked in a limited number of email clients, and eventually failed to gain widespread adoption. While Google still uses AMP internally as "Dynamic Email," the project has been largely abandoned.

BETTER ERROR HANDLING

The traditional `try/catch` method is not great. Better alternatives include Go-style return tuples and Monadic-style Result types, which treat errors as values and offer more explicit error management.

WHY DO WEBSITES STILL RESTRICT PASSWORD LENGTH? (REDDIT THREAD)

Websites still restrict password length, even when long, complex passwords are more secure. One commenter explains that the limitations aren't related to database size or DDoS prevention, but rather due to the input length limits of password-hashing algorithms like Bcrypt. Others suggest limits are holdovers from older assumptions about password memorability, legacy systems, or a desire to reduce customer service requests related to forgotten passwords.

TECH THINGS: OPENAI BUYS WINDSURF, GOOGLE RETAINS ITS LEAD, AND WHERE THE HELL IS APPLE?

OpenAI is in talks to acquire AI IDE Windsurf for around $3 billion, which seems like a high price given the competitive landscape. At the same time, Google's quiet but effective strategy of improving AI models and securing talent has led to its current lead, with models like Gemini 2.5 outperforming others. Apple's lack of investment in necessary resources and data collection has left them lagging behind in AI development.

INSIDE ARXIV—THE MOST TRANSFORMATIVE PLATFORM IN ALL OF SCIENCE

arXiv, created by American physicist Paul Ginsparg nearly 35 years ago, is an online repository that allows researchers to share findings and papers before peer review. The platform hosts over 2.6 million papers, receives 20,000 monthly submissions, and has over 5 million monthly users. Ginsparg is still deeply involved, constantly improving arXiv's quality control and filtering of submissions.

THINGS ZIG COMPTIME WON'T DO

While many languages support generics, serialization, and metaprogramming at compile time, Zig enforces strict boundaries: no access to the host machine during cross-compilation, no dynamic code generation (#eval-style mixins), no custom syntax or DSLs, and no runtime type info (RTTI). Instead, Zig has partial evaluation and specialization, allowing for expressive and safe compile-time behavior.
