For what it's worth, I just fired up my two portal gen 2 in the closet, updated them and the adb setting just worked. The adb UI is a little jank and doesn't appear to enable but it does actually work. Got them set up as Home Assistant dashboards

I'm a Meta employee so who knows if I'm in some magic gatekeeper but ADB definitely didn't work on these even as an employee before

Cool cool cool. So to confirm, you just installed the Home Assistant APK and that worked without issues?

It's a mixed bag. This only applies to the infotainment system and not the autopilot computer.

They've also revoked certificates from researchers personal cars in the past

FWIW, I think they share resources. I was able to crash the browser via a GPU benchmarking website while using autopilot. Autopilot disengaged and the “instrument cluster” lit up like a Christmas tree for a few seconds.

So I’d imagine an infotainment exploit would be able at least DOS the AP system.

Seems like there's plenty of non-lead bullet options though they're a bit more expensive.

Hashed hierarchical timing wheels is a cool very specialized data structure to make this efficient. The paper claims it's O(1) to start, stop and maintain timers which is much more efficient than O(log n).

Given there's n timers and O(1) operations I'm not sure where the O(n log n) fits in here. Possible in the minimum number of ticks?

Probably this bit from section 5

> If we can guarantee that all timers are set for periods less than MaxInterval, this modified algorithm takes O(1) latency for START_TIMER, STOP_TIMER, and PER_TICK_BOOKKEEPING.

I think that puts this in the same class as counting sort.

The paper says it's essentially bucket sort. Which was also my thirst thought when I heard about sleep sort.

Here's the source code for draw_fill: https://github.com/chowderman/xp-paint/blob/b6dfcce7f449d3bb...

have you tried torchscript w/ the C++ interface?

No. It looks promising. I should try it.

I think Tensorflow with Swift or Rust bindings may also work.

It goes Stable -> Beta -> Nightly in terms of closeness to trunk. I believe Preview == Beta and Preview Nightly == Nightly now. The Preview apps are going away since the new interface is releasing soon

Now I am even more confused

IIRC, the two "preview" ones are the new Firefox, the other three are the long-existing Firefox. So once the new Firefox replaces the old, the two "preview" apps won't be necessary anymore.

Some automated train systems (such as the Vancouver Skytrain) already do this for control.

From the SelTrac wikipedia page:

"in newer versions of SelTrac, the control signal is transmitted inside the running rails at radio frequency using IEEE 802.11 (WiFi) access points. "

Do you have a source on protonmail and creditkarma?

Chrome remote desktop works pretty well

But for remote control, it stops after every few minutes, asking the "controlled" user to click on a button to continue. Not so practical in a few situations.

What do you mean? I've never had it do that.

It always happens for me when accessing a Linux machine remotely. I can't find a screenshot now, so the next time I do it, I'll take one. It seems to be a security measure, to prevent someone from sharing remote access and then forgetting about it afterwards, but it makes for terrible usability.
