undefined === undefined — the auth bypass your AI wrote into your checkout

TL;DR An auth check that uses === where both sides can be undefined is fail-open — a missing config turns it from locked to open. The one secret missing from .env.example was the internal auth token. Unset in a deploy, undefined === undefined let every anonymous request through. Default to deny: validate types, reject empty, compare in constant time, and write the test that sends no credentials...

GEO is the new SEO — and most sites are failing at it

I built a tool that checks how visible your site is to AI engines like ChatGPT, Perplexity, and Gemini — and the results are eye-opening. Meta tags, backlinks, Core Web Vitals — the SEO checklist is well-known. But there's a new game in town: Generative Engine Optimization (GEO). When someone asks ChatGPT "what's the best tool for X?", does your brand show up? When Perplexity answers a question ...

Verify AI Token Cost Cuts with MgntUtils Stacktrace Filtering on your own data — Before You Touch Production

This article is for mid- and high-level managerial and technical decision makers. It is a follow-up to Cutting AI Token Costs with MgntUtils Stacktrace Filtering, a production case study of stacktrace filtering and AI token savings. That case study presents measured AI token savings — and I am also the author of MgntUtils, which creates an obvious trust problem: why accept my numbers on someone e...

Google AI Overviews Are Changing SEO KPIs as Clicks Decline in Search

Google's AI Overviews are making a longstanding SEO problem more acute: a search result can deliver visibility without delivering a website visit. Pew Research Center found that users were substantially less likely to click links when an AI-generated summary appeared in Google results, raising a practical question for publishers and enterprise marketing teams. If a brand is surfaced in an answer b...

Building a Multi-Agent AI Pipeline That Ships: LangGraph, RAG, and Evals That Matter

I spent 18 days building an AI product that converts research papers into audience-tailored PowerPoint presentations. Not a toy — a real deployed thing at doc2slides on Railway that anyone can use. The interesting parts weren't the "make it work" moments. They were the tradeoffs I had to make honestly, and the times I resisted the temptation to add a "clever" fix that would have made things worse...

0.3% In, 36% Out: Your Fine-Tuned Model Is Copying Your Prompt Examples

I run a fine-tuned Llama 3.3 70B on Amazon Bedrock. It generates short first-person narrative posts: a setup, a few lines of story, and a closing line that lands the point. Last week I noticed the closing lines had collapsed into a single template. Not similar in spirit, but literally the same grammatical shape, over and over: and that's how [someone] [learns/teaches] [something]. Roughly a t...

Why BusyBox in Your Alpine Containers Is a Bigger Problem Than You Think

When you pull an Alpine image, you are probably not thinking about what is actually running inside. Most teams see minimal and move on. Here is the thing: Alpine Linux is built on BusyBox. One binary. Everything else links to it. docker run --rm alpine:latest ls -la /bin/ | head -10 # lrwxrwxrwx 1 root root 12 /bin/ls -> /bin/busybox # lrwxrwxrwx 1 root root 12 /bin/cat -> /bin/busybox #...

I Stopped Scraping Business Directories and Built an MCP Server on Official Registry Data

I Stopped Scraping Business Directories and Built an MCP Server on Official Registry Data For a long time I built B2B lead-generation tools the way everyone does: scrape a directory, fight the anti-bot, re-scrape when the layout changes, pray the data is current. Then I found out the Romanian government publishes the entire company registry as open data — 4.2 million firms, refreshed mo...

An empty result is not an all clear

An infrastructure audit runs across your account and comes back with two findings on S3. You fix both, close the ticket, and move on. What the report did not tell you is that the role running it lacks s3:GetEncryptionConfiguration. Fourteen buckets returned AccessDenied on that call. The tool caught the rejection, wrote encrypted: false, and moved on to the next bucket. Some of those fourteen are...
