No, the key negotiation occurs between two clients. In the Magic Wormhole protocol, the number at the beginning of the Magic Wormhole phrase specifies a "nameplate" used to negotiate the "mailbox" which both clients (sen

Contra this assertion, drones are already frequently used around power lines, and as such, "finding hanging wires with a drone" is actually a very active field with fairly robust solutions. Not only are drones used for power line

mmWave radar is commonly used for detecting (horizontal) cables of similar thickness in a very common use of enterprise drones: power line inspection.

mmWave is the usual solution for this; I know that Amazon were at least testing using mmWave but I'm not sure if it made it to their production drones.

A gist is such a weird way to run a project like this! Basically what this seems to be about is adding full native acceleration support for Mac OS hosts to QEMU (audio, GL, etc.), to enable running a desktop Linux guest effectively, but it&

In the case of Apple AVD, it's a multi-stage system with a bunch of special primitives, orchestrated by a Cortex-M3 with firmware. Codec-specific frontends emit IR which a less specialized backend can execute. https://github

I agree in general; PCRs provide some basic degree of protection against this. Unfortunately, the position these management controllers are in often grants memory access, which renders all of the boot measurement type security methods usele

I see the point you're trying to make but it's really very orthogonal to this issue: this was an issue in a documented part of a documented feature, it's not some "deeply embedded" system management controller with

Almost all quadcopter brushless motors are constructed as “outrunners,” with a fairly thick, sturdy aluminum motor bell (rotor!) with strong permanent magnets glued inside of it and the stator in the center. I agree that they are not immune

Oh, yes, we 100% agree on this, the true root of trust for firmware execution exists before and independently of “secure boot,” and therefore, often not at all (and “secure boot” is a terrible name).

That’s fair - the first thing I’d put in my implant firmware would be a fake firmware updater, but I suppose trading guaranteed persistence for physical detection would be a reasonable tradeoff in some places.

I have never seen someone make a distinction between Secure Boot and boot verification on UEFI/x86, although I suppose it’s a valid one? I suspect the parent post is referring to Secure Boot in the colloquial sense it’s usually used fo

Wasn’t the implant supposedly (illogically) implanting custom BMC firmware? This actually always struck me as a somewhat unbelievable part of the story: why install a hardware implant when you could just clip the flash chip and implant some

Does anyone have benchmarks for Rosetta with TSO vs the Linux version with no-TSO? I guess it might be a bit challenging to achieve apples to apples, although you could run a test benchmark on OSX and then Asahi on the same hardware, I thin

They’re Bluetooth based and worked offline, but like so many “cloud” products, the app required an account which it seems to use to provision the key material for Bluetooth. I’m assuming they’re shutting down the account servers - so depend

At large scale I'd say MySQL is still a competitor for a few reasons: * Scale-out inertia: yes, cloud vendors provide similar shading and clustering features for Postgres, but they're all a lot newer. * Thus, hiring. It's eas
