CONTEXT PRUNING: CUT LLM TOKENS WITHOUT LOSING QUALITY

Context pruning is a technique that removes low-value elements from an LLM's input, such as tokens or passages, to reduce costs and improve LLM output, often resulting in up to 20x compression and faster latency. It works by mitigating issues like "lost in the middle" effects common in long context windows, but must be applied carefully as it can negatively impact structured data or multi-turn dialogue.

I DON'T THINK AI WILL MAKE YOUR PROCESSES GO FASTER

Organizations often have unrealistic expectations that AI will automatically resolve bottlenecks and speed up complex business processes. Delays in areas like software development typically arise from vague feature requests and incomplete documentation rather than a lack of technical execution speed. This means AI can't really help in these cases.

THE CTF SCENE IS DEAD

Frontier AI models have disrupted the open Capture The Flag (CTF) format by automating the reasoning and technical tasks that once defined human skill. These competitions have evolved into a test of computational orchestration and financial investment, making traditional scoreboards an inaccurate measure of individual security expertise.

EVERY AI SUBSCRIPTION IS A TICKING TIME BOMB FOR ENTERPRISE

Major AI providers are currently subsidizing enterprise subscriptions at a loss to encourage widespread adoption and weave their technology into core business workflows. The emergence of resource-heavy agentic AI has made this financial gap worse, as the actual cost of compute often dwarfs the flat monthly fees companies are currently paying. As these labs move toward public offerings, the pressure to achieve profitability will inevitably trigger a transition to expensive, usage-based pricing models.

HOW BRAZE'S CTO IS RETHINKING ENGINEERING FOR THE AGENTIC AREA

Braze shifted to AI-first engineering in a few months, with 60%+ of committed code now AI-generated. Adoption was driven by model quality (Claude Code, Opus 4.5) and a greenfield MCP server. Now the problem they're dealing with is inference cost, as engineers are spending tens or hundreds of dollars a day on using AI.

AI IS TECHNOLOGY, NOT A PRODUCT

AI is an essential underlying technology that will eventually pervade all Apple devices rather than manifest as a standalone "killer product" that replaces the iPhone ecosystem.

WHY I DON'T CHAIN EVERYTHING IN JAVASCRIPT ANYMORE

Transitioning from complex JavaScript method chains to explicit, step-by-step logic improves code readability, simplifies debugging, and avoids the performance costs of unnecessary data processing.
