Introduction

Trusted Execution Environments (TEEs) and SGX (Software Guard Extensions) plays a critical role in enhancing security by offering hardware-based memory encryption and isolation. SGX allows user-level code to allocate private regions of memory called enclaves, which are designed to be protected from processes running at higher privilege levels. This granular level of control and protection applies to other high-level processes running at the time, and even the operating system. By leveraging SGX, developers can enhance the security of their applications and protect sensitive code and data from unauthorized access.

TEEs and Intel SGX have various use cases in blockchain technology. They enable secure smart contract execution, ensuring the protection of sensitive data and logic. TEEs also facilitate confidential transactions, preserving privacy and confidentiality. Additionally, TEEs support privacy-preserving data analytics and secure oracles, ensuring data integrity and confidentiality. They can also play a role in decentralized identity systems, securely managing private keys and enabling secure authentication on the blockchain.

The two tribes of AI development

AI development is progressing along two distinct paths. One path involves companies raising significant capital at extremely high valuations. The other involves more focused entities taking a different approach. Both strategies have their advantages in different situations.

My First Impressions of Gemini 2.5 Pro

I've been using Gemini 2.5 Pro for just a short while now, but it easily feels like months. That's the funny thing about habits: the truly transformative ones integrate so quickly, you forget what life was like before. That's how it feels having left the landscape of previous LLMs after years inside what now feels like a more constrained environment. It wasn't a difficult switch, technically, but adjusting my workflow took a moment. Since then, it's consolidated into one massive, ongoing chat containing thousands of lines of code, ideas, and reflections – my primary interface for creative and technical problem-solving. It taps into that fundamental human capacity to adapt rapidly to powerful new capabilities. I find myself relying on its unique ability to tackle problems that stumped other models, its knack for creativity, and its skill in connecting disparate concepts. The raw numbers back up my subjective experience too – Gemini 2.5 Pro leads benchmarks like GPQA (science questions) and AIME (math problems) without needing specialized test-time techniques. It's not just marketing – there's a qualitative leap in how it approaches complex tasks. The benchmarks are impressive enough to mention specifically. Gemini 2.5 Pro has claimed the top spot on LMArena by a significant margin, outperforming both Claude 3.7 and GPT models. On technical benchmarks, it's reached 63.8% accuracy on SWE bench for coding tasks, and an impressive 18.8% on Humanity's Last Exam – a challenging benchmark created by hundreds of subject matter experts to test the limits of AI reasoning. Maybe it takes more conscious effort to switch tools as you gain experience, resisting the comfort of the familiar. But the reward here is rediscovering the sheer joy of leveraging a tool that expands your own potential – the speed, the intelligence, the massive 1M token context window allowing for unprecedented depth. And that context window is no gimmick – I've watched it analyze entire codebases (100,000+ lines) in a single session, maintaining coherence throughout. Where other models fragment understanding across multiple chats, Gemini can hold the entire conversation history plus documentation, making problem-solving feel genuinely cumulative rather than disjointed.

Devin and Me: One Month with an AI Software Engineering Agent

I've been using Devin from Cognition for one month now, but it easily feels like a whole quarter of development work. That's the funny thing about habits: they can compress or expand time depending on how much they change your workflow.

Learning Lua by Building a Roblox Guardian

Last weekend, my girlfriend and I were immersed in a Roblox gaming session when she presented an intriguing challenge: "Wouldn't it be cool if we could create something that follows us around in the game?" This question sparked my curiosity and presented the perfect opportunity to dive into Lua programming and Roblox scripting. I'm also currently watching Mythic Quest new season which is a sitcom about a group of people who work at a gaming company. Also you may be familiar that vibecoding games with Three.js is very popular these days on X.
