Decoupling Workloads: Strategies for Non-Blocking API Responses in Python Modern web applications demand instant feedback. Users expect immediate responses, and frustrating delays can quickly lead to abandonment. When an API endpoint performs computationally intensive or time-consuming operations directly within the request-response cycle, it creates a bottleneck that can cripple your backend sy

A critical kernel privilege escalation that leaves no trace on disk — and how it works It started with a blog post. On April 29, 2026, Theori's research platform Xint Code quietly dropped a URL: copy.fail. Within hours, security teams across the industry were scrambling. A 732-byte Python script — shorter than most .gitignore files — was rooting every major Linux distribution in existence. No race
Ledgers are the heartbeat of any financial companies, fintech or old school financial. Not the API gateway, not the mobile app, not the underwriting model. The ledger Banks have known this for centuries. Fintechs sometimes need to rediscover it the hard way. On fintech world Revolut runs multi-currency, multi-product financial infrastructure across 35+ countries. Stripe moves money and extends c
So far, we’ve seen: The model decides what to do The MCP server executes it But something is missing. Who actually connects these two? That’s the MCP client. The MCP client is: The component that connects the model and the MCP server, and manages the entire interaction between them. It’s easy to think: “The model calls the server directly” But that’s not what happens. 👉 The model only generates i
No build today. Just fundamentals. And honestly? It humbled me in the best way. Every automation I've built so far has relied on no-code/low-code tools like n8n to handle the logic. But I kept hitting moments where I thought , if I knew Python, I could do this faster, cleaner, and with more control. So I decided to fix that. And then I hit Exception Handling and File Handling and that's where thi
How I automated value discovery in binary oil markets using Python, Yahoo Finance, and the Polymarket API Polymarket lets you trade on the probability of real‑world events. There are often inefficiencies—especially when fear or greed distorts prices. But manually checking dozens of contracts and calculating fair probabilities is tedious. Yesterday, I noticed a juicy set of markets: What price will
