What Is Agent Memory? A Beginner’s Guide for AI Developers

TL;DR: Agent memory is stored state an AI agent can retrieve across sessions to maintain continuity. A bigger context window does not fix the problem. Once memory has to persist, be scoped to the right user, and be retrieved reliably, it becomes a data problem, and is often best handled in a database such as Oracle AI Database. Why This Matters You can build a convincing AI agent surpr...

Postmortem: How a Biased LLM Introduced Discriminatory Code in Our Hiring Platform

In Q3 2024, our hiring platform’s automated resume screener rejected 37% more female candidates for backend engineering roles than male candidates with identical qualifications. The root cause?

Farewell to F5: Building a Seamless Writing Workflow with Jekyll LiveReload

As a 20-year Linux veteran, I have zero tolerance for mechanical tasks that break my "flow." When using Jekyll for blogging, many developers fall into a repetitive trap: edit a paragraph -> switch to the browser -> hit manual refresh (F5). It’s a tiny friction, but like a memory leak in your code, it slowly drains your creative energy throughout the day. The solution has been hiding in the...

I made a React hook that turns any react-icon into a cursor

I was working on theming for a project and started messing with custom cursors. Ended up making a hook that takes any react-icon component, converts it to an SVG data URL, and injects it as a CSS cursor. No canvas, no external assets. Just React to SVG to cursor. You pass it a config object with a CSS selector and an icon and it handles the rest. You can set the size, color, hotspot (where the cli...

Everyone Talked About Gemini. Nobody Talked About the Two Protocols That Will Actually Change How You Build Agents.

This is a submission for the Google Cloud NEXT Writing Challenge I watched every hour of Google Cloud NEXT '26. And like everyone else, I was dazzled by the Gemini Enterprise Agent Platform rebrand, the 8th-gen TPUs, and the Workspace Studio demos. But the announcement I keep coming back to — the one I think will quietly matter the most to developers building real things — is something that didn'...

The five-call cross-border KYB workflow — walking a UBO chain across jurisdictions in a single prompt

The five-call cross-border KYB workflow — walking a UBO chain across jurisdictions in a single prompt KYB ("Know Your Business") used to mean "pull a company report and check the directors."

A Seond Brain For Your Agents

One of my agents was about to start a web search for design token naming conventions. The task was in my design system project, and watching the session live, I already knew what it would find: a mix of opinions, half-applicable patterns, and general best practices. The thing was, this question had already been settled in another active session. Different agent, same project, working on a related...

How TimescaleDB Expands the PostgreSQL IIoT Performance Envelope

TimescaleDB extends PostgreSQL with time-series features that dramatically improve IIoT performance. By partitioning data into hypertables, it maintains high ingest rates without slowdown, speeds up queries through chunk exclusion and continuous aggregates, and cuts storage costs by up to 90% with compression. The result is a scalable system that handles more data, faster queries, and lower costs ...

Testing a production Bash script: 38 tests without a framework

The context: a Bash script to display Claude Code rate limits in a terminal status bar. At first it seems trivial — a few functions, reading a JSON file, some formatting. But the script quickly ends up handling: JSON parsing with jq, time formatting with timezone, percentage calculations, Unicode progress bar generation, countdown logic. And above all: several edge cases (missing data, corrupted J...

Faked My Way Through a CS Degree — How Do I Recover Fast?

I’m currently in New Zealand on a work visa, and if I don’t secure a job in my field before it expires, I may have to leave the country. I have about 1 year and 10 months left, so time is limited. The problem is—I graduated with a degree in Software Engineering, but I don’t actually have solid coding skills. Throughou...

I built an AI hiring platform with zero coding experience. Here's what I learned.

I'm a recruiter. Not a developer. 4+ years in TA, 140+ hires across 18 countries. A few weeks ago I shipped a full-stack AI platform used by people across Germany, USA, India and beyond. No code written manually. Not a single line. Here's what actually mattered. The problem: Recruiters drown in CVs. Candidates apply into a black hole. Both sides losing from opposite ends of the same broken pro...

How We Helped an Agri Company Generate 500+ Documents/Day Without Rebuilding Their System

This case proved the opposite. Our first agriculture client already had a solid system for collecting operational data. But they were stuck — not because of data, but because they couldn’t turn that data into documents fast enough. We didn’t replace their system. We just removed the bottleneck.
