FWIW, I suspect Telegram animated stickers (or whatever it's called these days) may be Turing-complete.

yes -- browser permission model needs to be much more granular would be great if something like ublock is only able to disable dom elements, not insert them, for example, and has strong guarantees about not doing IO users are much more able to audit permissions than to audit changing code but permissions need to be 'shaped like' APIs or else they are too broad to provide power + safety together

It should start with access permissions being limited to user-specified (even if prefilled) list of sites/domains. There are extensions clearly meant for a single page (e.g. improving the UX), or a class of pages. I never install them, because even if those pages are not critical, the permission request is always scoped to "all data, every site", which means that e.g. this nice plugin decluttering YouTube could also exfil data from my bank's webapp.

pretty sure chrome provides this? or at least whatever build of chromium I am on, at least for local-unbundled extensions

Does this work for others not running the browser extension (or outside of your Slack organisation)? Also, Emoji has been part of Unicode for more than a decade...

Yes, your custom emojis will turn into images anyone can see. See: https://github.com/Schniz/fnm/issues/847#issuecomment-131372...

Oh hi. Unrelated to this tool but I use fnm every day and it's fantastic.

First time I used it it ran so quickly I thought it wasn't working properly.

Thanks for your hard work.

Given enough users, you'll have interesting statistics and metrics forming. What are you going to do with this? Might visitor IPs (viewers of Emoji inlined on GH, that is) be processed/retained?

Hey there! I plan to open source this soon so the source will be available and you can read it. It is really doing nothing but adding the emoji to GitHub. But I understand that the shadiest people say they are legit, so I’ll prioritize open sourcing the extension so others can review it :) sounds good?

That is a nice thing to do, but I think people will still be hesitant because there is no way to know whether that code you open-sourced is actually what's in the Chrome Store, or that the Chrome Store listing won't change ownership in the future. (Chrome extensions auto-update, so it's easy to ship users code that does something "new and exciting", and when dealing with software supply chain risk, "new and exciting"…

Not to mention that even the data being requested and stored is also organizationally sensitivite if leaked. Everyone's got some problem customer emoji or frustration with their cloud provider in there, which maybe wouldn't look great externally.

No, Github proxies and caches images through an intermediary (probably for privacy reasons amongst other things.)

I stand corrected, you're right! So seems to be 0 privacy concerns for viewers, here.

GH also seems to use the data-canonical-src attribute to reference the original URI.

I don't think they are. TGS is basically a subset of Lottie, which looks too simple to be able to do arbitrary computations: https://github.com/lottie-animation-community/docs/blob/main...
