Welcome To Narnia

Clothed in autumnal colours, streams tumbling beside us, waterfalls on every steep rockface, and the beauty of the long fjord leading to the sea. Magical.

Fjarรฐardalur, the "Fjord Valley," softly lit by sunlight from behind us and patched by cloud shadows ahead.

Looking like a scene from a fantasy novel, this is Mjรณifjรถrรฐur in eastern .

Edit: Thanks to @logi for the heads up.

A colour photo of a landscape of steep mountains on either side of a long fjord. Heavy cloud above is creating areas of sunlit rock between the shadows. The foreground is a rocky plateau with golden brown vegetation and streams running through it, brightly lit by sunlight from behind the viewpoint.

@GrapheneOS is being threatened by French authorities for refusing to add backdoors and they're dealing with coordinated attacks in French media right now. They're pulling out of France entirely, moving all their servers, and fighting off a wave of bullshit one-sided reporting that makes them look like they're helping criminals.

They need us to fight back. Support them however you can, whether that's a dollar, sharing their story, pushing back on the garbage news coverage when you see it, or just telling someone you know about what's happening. All of it matters because they're drowning in attacks from governments and media and bad actors who want them gone.

This is the only Android OS that actually makes me feel like privacy isn't just marketing. They fight for us now they need us to fight for them.

The EU is pushing Chat Control and creating an environment where governments feel empowered to threaten developers into compliance, and if we stay quiet we're letting it happen. Show up for them in whatever way you're able to.

This attack uses web push notifications to send legit-looking alerts to users, sending them to phishing pages. The push notification API gives attackers significant visibility into the target's web browser.

Probably should have notifications disabled by default anyway.

Fun low level problem: I have two different processors, of different architectures (Cortex-M33 and Cortex-A35). One is 32 bit ARMv7-M, the other aarch64.

They communicate through (among other things) shared access to an internal SRAM that you can use for shared variables, mailbox buffers, etc.

These SRAMs are mapped at the same address on both systems (but obviously zero-padded on the high side on the aarch64 processor).

Someone sent vee the most amazing study on a pediatric hospital contacting professional racing pit teams and asking them to advise on drafting a handoff procedure for ICU patients of the highest concern between wards.

And Ferrari and Williams went "You all are babies, let us show you how it's done" and cut the error rate in handoffs by like 20% and generally found that you need less training, not more, to do it correctly despite having a faster, more detailed protocol.

This is my shit, so much.
