To use the Montreal subway, you tap a paper ticket against the turnstile and it opens. But how does it work? And how can the ticket be so cheap that it's disposable? I opened up the tiny NFC chip inside to find out more... 1/15

After 6 months and about 333 commits I proudly present:

Faircamp 1.0 – A static site generator for audio producers
https://simonrepp.com/faircamp/

To recap the highlights of the past months and learn what's new in the final 1.0 release, check out the blog post: https://simonrepp.com/posts/faircamp-1.0/

Development of version 1.0 was made possible through the amazing support, funding and expertise of the @NGIZero programme and coalition, led by the @nlnet foundation and financed by the European Commission's @EC_NGI initiative – thank you so much for giving me and everyone benefitting from a better Faircamp this incredible opportunity!

Also, many thanks to all faircampers, contributors, testers, translators, bloggers, podcasters and encouraging voices for supporting this journey - for the final 1.0 release specifically to @branpos for release candidate testing, @n00q for bugreporting/testing, @limebar for the external artist page feature inspiration and @Vac for their diligent translation work.

Along with this release I've published multiple new documentation resources - from an official Linux/macOS/Windows tutorial to a 1.0 migration guide, from an overhauled reference manual to a beginner's guide to publishing faircamp (or any!) static sites - check out the website and recent posts in the #faircamp hashtag to discover them!

That's all!

Unsigned and unencrypted radio protocols control a large amount of street lamps and power plants, threatening European grid stability.

All you need is a large antenna, aka. putting a wire on a kite.

Didn't expect this one to have a #synthdiy angle! 🤩

I would complain about #38c3 streaming issues but the very existence of the service is so impressive I'll just thank the Angels now: thank you!

(Edit: in case of problems, downloads still work)

To little surprise it seems that multiple #antivirus vendors have been ignoring COM hijacking as a self-defense bypass and LPE vector since at least 2018, when I first published about this technique (see my prev post).

At #38c3 guys from Neodyme demonstrated some more elegant exploits than my initial PoCs, nice work! My German is rusty but I think I'd have some comments about proposed solutions :)

This looks remarkably similar to my previous research on #antivirus privescs:

Can't wait to see what these guys found!

Does anybody have a tap for a keg of beer (10l, DIN 6647-1) with them? Maybe a top vent as well. We Cologne people have beer, but no way to get it out of the keg.

If you can help us out of our misery, that would be great. And you'll get beer! 🍻
