Somewhere right now a guy at a bar is making a stranger sign an NDA on a napkin. For an app idea. Just sit with that. That napkin is going in a drawer. The drawer is a graveyard. Quick tour. Exhibit A: bro we should open a bar Two beers in, you're suddenly a hospitality mogul. Picking a name. Arguing about taco night. By the time the check comes, the bar is already dead. It died of "let's talk about this again soon," which never happens. Exhibit B: bro we should st...

We all know the grind of working with data, even with AI tools: every experiment starts with re-explaining everything, every iteration needs you to prompt, wait, review, correct, and repeat. And the moment you close the session, everything learned is gone. It makes us the bottleneck, and this hinders human-AI collaboration... So I built 𝐎𝐩𝐞𝐧𝐃𝐚𝐭𝐚𝐒𝐜𝐢, an autonomous agent purpose-built for DS/ML, and tested it on Kaggle. I enrolled in a recent competition, ran the agent with no hints, no guid...

Learn how to organize React projects for scalability, maintainability, and team collaboration. Introduction As React applications grow, one challenge consistently emerges: project organization . A folder structure that works perfectly for a small side project can quickly become a nightmare when multiple developers contribute to a production-scale application. Whether you're a junior React developer preparing for interviews, a mid-level frontend engineer looking to improv...

I build algorithmic trading bots as a side project. Nothing fancy — just small strategies that trade US equity options automatically. The problem I kept running into wasn't the strategy logic. It was the data. Every time I wanted to pull real-time options chains, Greeks, or IV, I had two options: Pay $99+/mo to a data provider Scrape something I probably shouldn't be scraping Neither felt right for a hobbyist project. So I built Market-Options — a simple REST API for US equit...

Having spent over 25 years in software development and managing countless Linux environments, I've accumulated a vast collection of custom bash scripts, containers, and CLI tools. Remembering their exact paths and managing them efficiently directly from the terminal is a common challenge. To solve this, I built mytuis . mytuis is a small, attractive terminal UI for managing a personal catalogue of applications. It is built with gum and plain bash, with persistent storage in a human-readable Y...

Originally published on Mohamad Alsabbagh's Blog . AI coding assistants are excellent at compressing known work into fast drafts. That speed is the preface boost : routine implementation arrives almost immediately. The hidden risk is that teams begin treating the model's first plausible answer as architecture. Because LLMs are trained and aligned around historically common patterns, they can pull engineering teams toward Generative Monoculture : less diverse solutions, narrower explo...

Debugging authentication in web apps is painful. You need to test the same flow as five different user types — new visitor, returning user, admin, expired session, logged-out — and the easiest way is to constantly create new accounts or clear all your cookies and start over. There's a faster way. These five techniques use direct cookie manipulation to simulate any auth state without touching your database or creating dummy accounts. I use CookieJar for most of this — a free Chrome extens...

The cryptographic keys that secure your computer's boot sequence will start to expire on June 24. Here's what that means for you.

With Apple raising prices soon, you can save a lot of money by buying a used handset or upgrading an older device—safe in the knowledge that it'll last longer than ever.

Stainless-steel pans may lack nonstick coatings, but they’re unfussy, they sear well, and they’re built for a lifetime of hard work.

Sure, anyone can use OpenAI’s chatbot. But with smart engineering, you can get way more interesting results.

Network-attached storage (NAS) provides accessible shared space on your home network. After testing, these are my favorite NAS devices.

Wooting’s 60HE v2 isn’t just a terrific Hall Effect keyboard. It’s a fantastic keyboard period.

The Xperia 1 VIII marks an attempt at a step change for Sony's flagship phone line. Not only has it had an aesthetic overhaul, but Sony has also revamped the camera system, dropping the continuous optical zoom telephoto that's defined the last four generations of Xperia phone. It's not all different. Sony staples like a […]

What: AMD shipped ATOM + ATOMesh , a ROCm-native LLM serving stack whose headline trick is prefill/decode disaggregation — splitting the two phases of inference onto separate pools of GPUs instead of crowding them onto one. Why: Prefill and decode have opposite bottlenecks — prefill is compute-bound, decode is memory-bandwidth-bound — so running them on the same worker wastes hardware and lets one long prompt stall everyone else's token stream . vs prior: A co-located server (v...

So here's what happened: the CTO Playbook for AI Agent Data Analysis on a Budget Six months ago my engineering team was burning roughly $14,000 a month on a single AI agent data pipeline. The model was great. The latency was fine. The output quality was honestly impressive. But the bill was eating our runway, and I had to make a call that would have felt absurd a year earlier: rip out a perfectly working stack and rebuild it from scratch. This is the story of how I did it, what I learned s...

This is a submission for the June Solstice Game Jam . An AI assistant remembers everything Until it doesn't I spend a lot of time building software around language models, and sooner or later every system runs into the same problem: context is finite. No matter how capable the model is, important details eventually disappear. A user's preference vanishes. A critical fact drops out of context. The system either gives a generic answer, retrieves incomplete information, or ...

Every time I asked Cursor about our auth flow, it would open 8-12 files, read through each one, and burn through tokens before even starting to answer. For a React Native codebase maintained by 6 developers, this adds up fast. I lead a front-end team building React Native apps. Cursor is our primary IDE. And while Cursor is great at understanding code, the way it retrieves context — by grepping and reading raw files sequentially — doesn't scale well on larger projects. Then I found Graphi...

In the last post, we killed the "Tool Abstraction" layer. By replacing 50 brittle JSON-RPC wrappers with a single eeva process (Elixir on the BEAM). Here is how we moved our agent from text-based hacking to actual AST-aware refactoring. The Problem: The "Diff" Illusion Standard agents "edit" files by outputting search blocks: Plaintext <<<< SEARCH def hello_world, do: "hi" ==== REPLACE def hello_world, do: "hello elixir" >>>> This is f...
