AppExchange security review: what it checks

What an AppExchange security review preflight actually checks The email arrives looking innocent enough. "Congratulations on submitting to the AppExchange Security Review."

[Gemini API in Action] Adding a "Detailed Research Report" Button to a LINE Bot: Using Google Search Grounding to Turn Summaries

Background My LINE Bot has always had a summary feature: you drop a URL in, it crawls the content, generates a summary, and attaches a social media post draft along with a button to save it as a bookmark. This feature has been around since 2024, but it has always only solved the "what is this about" problem. I often find myself wanting to know three other things: What is the backgrou...

What a Code Completer's Eval Never Measures: Ghost Text

pycomplete is a code completer I built out of a research repo's own findings, and it works. Index numpy and it reports this, on 24 files it has never seen: indexed 441 files / 2,065,825 tokens in 6.9s; evaluating on 24 held-out files alpha=0.45 cache_beta=0.5 positions: 2000 top-1: 0.546 top-5: 0.739 (11.1 ms) 54.6% of the time, the token you were about to type is the one at the top o...

The signal everyone blocks on is the one that is usually wrong

Datacenter IP is the first thing most teams block on, and on its own it is a terrible reason to refuse anyone. It tells you the request did not come from a phone or home broadband — it came from a rented server. That is genuinely useful information. It is just not a verdict, because the population it catches is mostly VPN users, and VPN users are disproportionately the security-conscious, privacy...

Feature Registry & Governance: Standards and Workflows

The symptoms are familiar: models that suddenly fall over after a schema change, a dozen near-duplicate features named user_ltv_v1, user_ltv_final, user_lifetime_value, and onboarding that requires rebuilding features from scratch for every new model. Those outcomes are manifestations of weak governance—no single source of truth for feature definitions, no version history tied to compute logic, an...

I built a unified memory and MCP gateway for AI agents that syncs in ~12ms. Here is how it works.

If you were building autonomous workflows, you were probably suffering from "framework fatigue." Every time you switched between IDEs like Cursor, terminal agents like Claude Code, or browser-based assistants, you had to reconfigure your tools, re-authenticate your keys, and re-index your files. You were manually duct-taping agents to a dozen different local MCP (Model Context Protocol) servers, ...

A Beginners Guide To Closures

Introduction If you've been writing JavaScript for some time now, you've probably used a closure without realizing it, maybe in a setTimeout, an event listener, or a function that returns another function. Closures are one of those concepts that feel abstract in theory but are everywhere in practice once you know what to look for. They also have a reputation for being confusing, mostly...
