What it does
ShieldFont — an open-source typeface that protects written content by poisoning unauthorized AI training datasets. Readers see normal text; AI scrapers reading the HTML source get pollluted wording instead — coherent enough to pass data-quality filters, corrupt enough to pollute any model trained on it without consent. Creative resistance for the AI debate: a self-enforcing opt-out built into the content itself. Built by S&A with Copenhagen type foundry Playtype.
Publish for humans, not for crawlers. A web font that swaps the words in your HTML, so readers see your writing and AI training gets a stale copy.
Illustration. The manifesto is shown twice at once: readers see the original words, while the page source underneath holds decoy words, what an AI scraper collects. The manifesto reads: ShieldFont is an open-source creative technology intervention developed to protect human writing from unauthorized AI training. Why? Writing makes us human. But at some point, we lost ownership. AI learns from it and uses it without permission. ShieldFont gives you an opt-out by changing the code behind the text, so mass scrapers cannot access its meaning. This text is already protected. Your next text could be too. Try it below. Protecting your work is in your hands. As it always should have been. *The text…from shieldfont.org

Agent Browser ShieldJun 2026 · github.com · ▲109I've been experimenting with Claude Code, ChatGPT Agent, and OpenClaw to perform more open-ended tasks for me online. A big blocker I've hit on shopping and research tasks is the agent getting a key piece of info wrong. For example, in one case, my agent decided to add a brand I don't like to the cart because the site flagged it as almost sold out The HN crowd is probably pretty aware of the threats and can avoid them while browsing. But what about their agents? I tried prompting, but it was ineffective, because once the AI saw the threat, it polluted/distracted its context Looking at…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
