LEVERAGING ELIXIR'S HOT CODE LOADING CAPABILITIES TO MODULARIZE A MONOLITHIC APP

Elixir's hot code loading can be used to create client-specific features within a monolithic application fast. This approach involves dynamically loading and compiling client-specific LiveView apps at runtime, isolating client code during the main app's build process. By removing client-specific code during build time, it enforces dependencies and makes testing easier.

FORGET BORROW CHECKERS: C3 SOLVED MEMORY LIFETIMES WITH SCOPES

The C3 language has a Temp allocator, a region-based memory management system that simplifies memory handling. This allocator automatically resets when execution leaves its scope, preventing memory leaks without needing manual cleanup or garbage collection. By tying memory lifetimes to scopes, C3 is able to have efficient, performant memory management without the complexity of traditional methods like reference counting.

ARTIFICIAL INTELLIGENCE IS A COMMODITY, BUT UNDERSTANDING IS A SUPERPOWER

While AI is increasingly accessible, the ability to understand and effectively apply it is still uncommon. AI can generate code, but it doesn't have the human capacity to fully understand project goals, system complexities, and the deeper intention behind the code. Therefore, devs who have a strong understanding of both technical implementation and strategic purpose will be the most valuable.

PARSE, DON'T VALIDATE AKA SOME C SAFETY TIPS

Instead of repeatedly validating input throughout the system, it's better to parse untrusted input into specific, opaque data types (like `email_t` and `name_t`) at the system's boundary. This makes sure that internal functions only handle well-defined, structured data, reducing attack surfaces and preventing misuse of raw character pointers.

GOOGLE'S REAPS THE REWARDS AS OPENAI'S DEAL TO ACQUIRE WINDSURF COLLAPSES

OpenAI's planned $3 billion acquisition of AI coding startup Windsurf collapsed after Anthropic cut off Windsurf's access to its Claude models, creating an opening for Google to swoop in. Google hired Windsurf's CEO, co-founder, and key researchers for $2.4 billion through an "acquihire" deal that avoids regulatory scrutiny while still getting talent and technology licensing without taking equity in the company.

HOW I FOUND A BYPASS IN GOOGLE'S BIG ANTI-ADBLOCK UPDATE

This dev discovered a bug in Google Chrome that allowed MV3 extensions to bypass the intended restrictions on `webRequestBlocking`, a feature necessary for adblockers that Google was phasing out. The bug exploited a loophole in how Chrome handled WebView IDs within the `webRequest` API, allowing extensions to spoof permissions and reinstate the blocking functionality.
