I've just shipped a tour + much better experience for logged out users.

You can view at https://bridge.brannon.online (logout via stats if you need to).

Thanks for the feedback!

That's good feedback. Would it help if the sign up process happened after the welcome tour?

Bridge is by far the most complex card game I've ever played, but it also has one of the most rich formats for competitive play in Duplicate Bridge.

This app features unlimited deals without paywalls or ads, and tracks your rankings and stats over time so you can watch yourself improve.

Oops, forgot to link the PR, lol

I've proposed these changes to shy away from the claims of "Run unsafe code safely" in this crate.

Let me know what you think, or if you have any additional suggestions.

I'm proposing that change here: https://github.com/brannondorsey/mem-isolate/pull/44

Let me know if you think this wording could be improved or I'm missing any details.

Thanks for that suggestion.

I'm adding a few more limitations in this PR: https://github.com/brannondorsey/mem-isolate/pull/44

I know async-signal-safety is particularly important for, you know, signal handlers. But aside from those, and the multi-threading use case you describe, is there another use case where calling non async-signal-safe code from inside this module would lead to issues (that isn't covered in the new limitations)?

I can add another limitation is issues can transpire if the code you run in `callable()` isn't async-signal-safe, but I'd like to offer a few additional examples of gotchas or surprises to point out there.

> have no hope of doing better

Yeah, this is really the main use case. Its a relatively simple solution when you can't do any better.

I think that's particularly helpful when you're invoking code you don't control, like calling into a some arbitrary C library.

New comment by braxxox in "Why Is This Website Port Scanning Me?"

braxxox — Wed, 20 May 2020 17:37:22 +0000

Port scanning from a web page, combined with DNS rebinding, can present a really nasty attack, and can effect an entire private network, not just localhost.

Some more info here: https://medium.com/@brannondorsey/attacking-private-networks...

Example code: https://github.com/brannondorsey/dns-rebind-toolkit

Disclaimer: I performed some of this research a few years ago. So those resource suggestions are my own, but they feel very relevant here.
