JSK Shield

The ad blocker that shows you the rule it blocked with

What it does

JSK Shield is an open-source ad and tracker blocker for Chrome, Edge and Firefox (GPL-3.0). Every other blocker shows a count. JSK Shield shows the request it blocked, the exact rule that matched, and the list it came from - then lets you allow just that one request on that one site. When a page breaks, guided recovery tries the least destructive fix first. Everything runs on your device: no telemetry, no paid allowlist. Blocking is free forever; an optional Family plan adds parental controls.

JSK Shield blocks ads and trackers entirely on your device. Open source, no telemetry, no paid allowlist, and a one-click explanation of why anything was blocked. Works with no account.

JSK Shield is a free, open-source ad and tracker blocker for Chrome. It works the moment you install it — no account, no sign-up, nothing sent about you. And when a blocker breaks a page, JSK Shield is the one that shows you why and fixes it in a click instead of leaving you guessing. Most ad blockers ask you to trust them. JSK Shield lets you check. It runs entirely on your device, collects nothing, and its code is open source under the GPL-3.0 licence — so every claim on this page is verifiable, not marketing. Where JSK Shield is genuinely different is what happens when something goes wrong. Every other blocker shows you a count. JSK Shield shows you the request that was blocked, the…from jskapps.com

    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.
