Tessera
Reviewable PCI evidence for payment pages and email
What it does
Tessera inventories served payment-page scripts plus SPF, DKIM, and DMARC evidence. Start with a free bounded check; eligible results unlock written remediation or a 72-hour hash-chained ledger. Evidence for qualified review - not a compliance determination.
A free static inventory of the scripts your payment page serves: resolved hosts, observed integrity, and your authorization decisions. PCI DSS 4.0.1 requirement 6.4.3.
A free static inventory of served scripts, resolved hosts, observed integrity, and your authorization decisions. No account. No card details. Submit only a page you own or are authorized to inspect. The next view runs the bounded check without putting your target in the address bar. Behind a cart or login? The full reader also accepts deliberately pasted served source. A static read of the served document only. Runtime-injected scripts do not appear, no request is made to any listed host, and the page is never executed. Response headers are outside this scan. Live 11.6.1 monitoring adds header and script-body observation; this sheet does not. The free check needs no account or card details…from qi.toledotechnologies.com

- IMI made a free interactive and payment processor database for startups2025 · sourcefees.com · ▲8
Hello everyone. I'm a relatively new developer and I started my first project to go full production recently. It is a directory of payment processors and payment service providers. It's free to use and gives detailed info on their pricing, business model, supported business types, available countries, prohibited businesses and high risk business support. So far only 40 have been added with more to come. And I allow processors to contact me so that they're details can be added to the database. I'll eventually automate this and add verification the months to come. I hope you'll find it useful.…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
