Interesting talk from 39c3: https://gpg.fail including my favourite classes of issues ANSI escape spoofing and abusing CR. A partial response from GnuPG is here https://www.gnupg.org/blog/20251226-cleartext-signatures.html — although there’s other issues that do seem more fixable. IMO better to use age if it makes sense and/or ssh signing (e.g. for git commits)

@opentechfan@exquisite.social @OpenBSDAms@mastodon.bsd.cafe @h3artbl33d@exquisite.social it’s often worth considering if you can turn the problem into a set of files, e.g. if the config file format supports includes or there’s a .d style config. That way you don’t need templating, or at least the templating is limited to a few files. Even with ansible that may result in easier to reason about deployments.

Was just looking at the possible specs of the Lenovo X1 Carbon Gen 14. Rather expensive option here! Also does anyone know what the $20 "Haptic Touchpad" means in terms of actual hardware?

I probably should have polished my @ComfyConAU@infosec.exchange talk. Instead I got sidetracked into wondering just how much I could tunnel over DNS: https://dgl.cx/2025/09/images-over-dns

@sash this takes advantage of the fact (some?) browsers by default load a blank iframe, so it's fewer characters than . Works in Chrome at least.

@nikclayton@mastodon.social @mwichary@mastodon.online (also this definitely works in Apple iOS apps, other apps may or may not actually implement this…)

@freddy @sash interesting… https://developer.mozilla.org/en-US/docs/Web/API/SVGElement/load_event claims it doesn’t work in Firefox and references a 15 year old bug… but yes, that would get a few more characters :)
SVGElement: load event - Web APIs | MDN
MDN Web Docs

SVGElement: load event - Web APIs | MDN

The load event fires on an SVGElement when it is loaded in the browser, e.g., in the DOM in the case of an embedded <svg>. It is basically the same as the standard load DOM event.
