And that, of course, leads to the downsides of QR codes, e.g., https://www.owasp.org/index.php/Qrljacking - the misuse of QR Codes to do not so nice things. It seems to me that folks who use them on TW sites that allow federated content are going to be implicitly trusting every other person with write access to that federated content. Even static TW's on public sites are going to have the same implications. It does not seem that there is anything keeping from me putting a QR Code in a tiddler claiming to be my contact info but instead sending the unsuspecting user to a phishing web site first, or a Rick Roll. Or it might not be me but someone who simply has obtained my login information to that publicly accessible content. Maybe using Qrljacking. The TW community seems to be a very helpful one. But with its popularity and capabilities increasing I am not sure that will remain universally true indefinitely. A google of 'qr code vulnerabilities' mentions might give you pause. -- Jonathan On Tuesday, October 18, 2016 at 9:01:16 AM UTC-4, Jeremy Ruston wrote: > > There’s been a rash of updates to v5.1.14 in the last 10 days, making it a > good time to have a look at the prerelease at > http://tiddlywiki.com/prerelease > > I’d like to highlight the new QR code generator plugin (installed in the > prerelease so that you can try it out easily).
