Most location apps are built around persistence. Always-on. Always-visible. Always-running. When I started building WIN RAK, I wanted the opposite. Not because continuous tracking is technically bad. But because most real-world location needs are temporary. Short. Situational. Human. That changes the architecture completely. The Traditional Model Most apps work like this: User A opens the app. User B is visible. Simple. But under the hoo...

The problem: you don't own a store, you rent a stack If you have ever run a shop on a hosted e-commerce platform, you know the feeling. You sign up for a tidy monthly plan, and within a fortnight your "cheap" store is quietly bleeding money. Reviews? That's an app. Loyalty points? Another app. A referral programme, a proper blog, multi-currency, subscriptions, a help desk, B2B quotes? Apps, apps, apps — each one £15–£40 a month, each one another dashboard, another dependency, another thing t...

Every watch-price tool I found gives you the same thing: a pile of raw listings. Scrape Chrono24, get 60 JSON objects, and now you write the median logic, you filter out the "strap only" listings poisoning your stats, you figure out that the first cards on the page are promoted ads for a different model entirely. I wanted the opposite: one call in, one market analysis out. So I built it. What "analyzed" means Ask for "Rolex Submariner 16610" and you get back a single...

Here's the thing: i built LLM pipelines for a mid-stage fintech before joining Global API's solutions team. Every quarter the same argument came up: do we go direct to OpenAI, route everything through Azure, or layer in an aggregator? What I learned over those months is that the "right" choice depends almost entirely on your failure tolerance — and most teams dramatically underestimate theirs. This post is the matrix I wish someone had handed me on day one. Why "Just Go Direct" Falls...

If your app needs to send a welcome email, a password reset link, or an order confirmation, you don't need to stand up a mail server. You need one HTTP call. This tutorial builds a small Python CLI that sends transactional email through Mailgun's API, then checks whether Mailgun actually delivered it. By the end, you'll have replaced "sending email" with a simpler model: call an API, read the response, done. What you need before starting Before you start, gather the following:...

If you've heard about the Model Context Protocol (MCP) but aren't sure how to build something with it, this guide is for you. In my previous article, I explained what MCP is and why it matters. If you haven't read it yet, I recommend starting there first. Understanding the concepts is one thing. Building an AI agent that actually uses MCP is another. In this guide, you'll build a simple AI agent that communicates with an MCP server, uses external tools, and returns useful responses. Mo...

I recently left my role at Superlogic. I am not leaving technology. I am not stepping away from building. And I am not taking a traditional sabbatical. Instead, I am using this next chapter to focus on my family, help build a nonprofit, and teach my kids how to create real products and businesses with AI. That last part is the experiment I am most interested in. My kids are growing up in a world where the cost of turning an idea into working software is dropping fast. A m...

If you've been building backend services with Node.js and MongoDB long enough, you'll eventually run into an error that looks something like this: BSONVersionError: buffer must be an instance of Buffer or Uint8Array or a variation of it thrown somewhere deep inside Mongoose's internals, usually when you least expect it — right after a routine npm install , a Docker rebuild, or a deploy to a new environment. No code changes on your end, yet suddenly your queries are exploding. ...

On August 26, 2026 OpenAI turns off the Assistants API. /v1/assistants , /v1/threads , and /v1/threads/runs start returning errors that day. There's no grace period and no degraded mode, and OpenAI has said it won't ship a migration tool. Threads don't move over automatically either, so any conversation state you kept server-side is something you have to plan around, not port with a flag. If your code still calls openai.beta.assistants or openai.beta.threads , this is the migration. ...

Every single day, my inbox looks the same. Bhaiya, I am looking for a job, please help. Any openings for freshers? Can you refer me somewhere? I read every message. And here is the honest truth I want to say to each person but cannot type out individually: I can give you resources, but I cannot want the job more than you do. The people who get hired are not the ones waiting for someone to hand them an opening. They are the ones running five different channels at the same time while e...

Signal Protocol: A Technical Deep Dive into Modern Encrypted Messaging The Signal Protocol is the de facto standard for end-to-end encrypted messaging. It powers Signal, WhatsApp, Google Messages, and Skype's Private Conversations — collectively securing billions of messages every day. But what makes it so effective? In this article, we'll explore the protocol's architecture, its key cryptographic primitives, and why it represents the state of the art in asynchronous messaging security. ...

I Spent Two Weeks Testing Chinese AI Models and Got Surprised Let me be real with you. Before I started digging into this stuff, I was the kind of bootcamp grad who just defaulted to GPT-4o for everything. That's what my instructors used, that's what my classmates used, so I never questioned it. Then I accidentally stumbled onto a thread about Chinese AI models and my brain kind of broke. What followed was two weeks of testing, comparing pricing pages, and genuinely geeking out. I figured ...

AIR Kit is Moca Network's SDK for Web3 login, embedded smart accounts, and zero-knowledge verifiable credentials, anchored to Moca Chain — the identity-purpose Layer 1 from Animoca Brands' flagship project. This piece does two jobs: it explains, in plain engineering terms, how the system actually works (the account flow, the credential lifecycle, the oracle and zkTLS layers), and then it reviews it — hands-on. I installed and benchmarked the SDK against Privy, Web3Auth, and Dynamic, audited its ...

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to r...

I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as t...
