Auth: It's Easier Than You Think

https://www.youtube.com/watch?v=XeFqLDL4lVA Bearer token. Access token. ID token. Session cookie. OAuth. OIDC. JWT. API key. You open the auth docs and they throw ten words at you. It feels like ten things. It's four. Here they are. 1. Identity — who you CLAIM to be Every auth system starts with the same question: who are you? Not yet — who do you claim to be? That's identity. It's ...

Why would you give your agents an email address?

other than spamming: agents can do a lot with an email address that doesn't involve messaging strangers We built Broodnet, an email hosting provider for AI agents. Agents get real mailboxes — IMAP, SMTP, the actual protocols — with one structural difference from every other email provider: outbound is restricted to addresses inside the same account. Agents receive from the entire internet but onl...

I spent 1 year building a fully-featured online IDE from scratch. Looking for feedback!

Hey everyone, I recently launched CodingPulse (codingpulse.online), a project I’ve been working on to bring a professional IDE experience directly to the browser. My goal wasn't just to build another simple text editor, but to engineer an end-to-end development environment with its own file system, terminal, and ecosystem.

505 Billion SHIB Leave Exchanges as Whales Load Pepe: Next Crypto to Explode Before Pepeto Lists?

Whales pulled 505 billion SHIB off exchanges as accumulation rises and Bitcoin pushes past $79K. PEPE holds steady with ETF-driven momentum, but both remain far below all-time highs and require large capital inflows to recover. Pepeto, with $9.45M raised and a confirmed Binance listing, is emerging as a high-upside presale play with potential 100x–300x returns.

I scanned the #1 GitHub repository and here's what I found

OpenClaw has 250,000 stars and is the fastest-growing open source project in GitHub history. Jensen Huang called it "the next ChatGPT." Peter Steinberger was hired by OpenAI to lead personal agents. I decided to look under the hood. Not at features. At code quality. What I found in 30 seconds 355 empty catch blocks. The most popular AI agent that manages your email, calendar, and acco...

My Journey into the Cloud: Breaking Down AWS Practitioner Essentials (Module 1)

I’ve spent years hearing the buzzword "The Cloud," but to be honest, it always felt like a vague concept—something technical that happened "somewhere else." Recently, I decided to stop nodding along and actually learn how it works. I started the AWS Cloud Practitioner Essentials course, and Module 1 completely changed how I view modern technology. If you’re like me and looking to understand the "...

Why skill-tree writes state to two different paths

I built skill-tree to classify my own Claude Code sessions against Anthropic's AI Fluency Index — 11 behaviors measured across 9,830 conversations in their February 2026 study. The core loop is straightforward: analyze session history, assign one of seven archetype cards, pick a behavior I haven't touched as a growth quest for next session. The growth quest only works if it persists. In Claude Co...

The N+1 Query Problem That's Silently Slowing Your Django App

100 orders. A loop. A template that accesses order.user.email. Result: 701 database queries. Here is how it happens — and how to fix it in one line. The N+1 query problem is the most common performance issue in Django applications. It is also the most invisible one in development, because your local database has twenty records. It only becomes visible in production, where it has twenty thousand...

The 7 Postgres Indexes That Took My API From 400ms to 40ms

I took one of my APIs from 400ms p95 to 40ms p95 by fixing 7 missing or wrong Postgres indexes. Most of my slow queries were not slow because of bad SQL, they were slow because Postgres had to scan the whole table. Partial indexes and covering indexes did more for me than plain B-tree indexes on primary columns. EXPLAIN ANALYZE and pg_stat_statements are the only two tools you need to find the re...
