Implementing WebMCP on a Recruitment Website

Thinking about what, exactly, the future of a website “looks” like in the agentic era is a challenging proposition. It might be that in most cases, our future viewers/readers/customers can do everything, from their chatbot of preference while never visiting your site. WebMCP is a part of this puzzle.

I built a film camera simulator in a single HTML file here's how

Launched today: faxoffice1987.com — 8 film cameras simulated in Canvas 2D. The constraints I set myself: One HTML file No build step, no dependencies, no npm install Runs offline from a USB drive No backend, no account, no uploads The hard part: per-pixel color science. Each film stock (Tri-X, Portra, Velvia, Neopan Acros) has its own render path. Not a filter on top — a decision at the pix...

Sensitive Data Exposure - The Bug That Looks Like a Feature Working Correctly

The API response came back 200. The data was correct. The test passed. Nobody noticed the response body also contained the user's hashed password, their internal account ID, a debug flag set to true, and a field called admin_notes that was never meant to leave the server. Sensitive Data Exposure does not look like an attack. It looks like a feature working correctly. TL;DR Sensi...

I got fed up with GitHub Trending, so I built my own ranker. Here's what I learned.

So we run a tech newsletter, and I used to spend my whole Sunday trying to find repos worth writing about. Github trending was useless. it's either huge projects everyone knows already or random stuff that got lucky on HN and then died. so I got annoyed enough to build something. it works way better. but the real lesson was how much junk you have to filter out before the ranking even matters. ...

When should you use canary deployments?

One solution for a tricky or high-risk deployment is to leverage a canary deployment. In a canary deployment, new features are rolled out to a small subset of your customer base with no fanfare. If things go well: hooray! Canary deployments are ideal for times when a deployment might go sideways or the feature might not work as expected. By utilizing a canary release, you have minimized the risk, ...
