I wonder how much help they had by asahi doing a lot of the kernel and ecosystem work anablibg 16k pages. RISC-V being fixed to 4k pages seems to be a bit of an oversight as well.

0xDD - I feel like that's pretty decent these days.

I would be shocked if a judge interpreted that to include essentially willful perjury (or at least false statements) to a national security agency.

You don't need that as much on modern protocols. The point of 8b/10b or 64b/66b is that it guarantees enough edges to allow receivers to be self clocking from the incoming bits being more or less thrown directly into a PLL.

In the cases where I do this, it's when I try really hard not to actually expose the state machine to tests anyway because there's a better way to hit them in tests with their expected inputs and outputs rather than an implementat

I imagine that more people applying to MIT than they can accept have maxed out all of the opportunities they've been given.

I have used function local enums for the states of a function local state machine pretty successfully.

Just going to through out there that you don't need a custom kernel driver to do this on Android. There's a userspace gadget API; you only need a rooted phone to have the permissions to access the relevant device and config files

A rooted android can. https://github.com/tejado/android-usb-gadget

I don't think that SoC makes sense. Because of how the pad frame would work for the ddr and and pcie, you'd have a bunch of empty silicon if you only stuck a couple A73s and a simple GPU in it (and at this scale, the Ethernet is

Depends on the team. I almost prefer juniors to make some mistakes and spend some time trying to figure it out on their own. There's a good chance they won't figure it out, but the journey they go on is a lot of time worth it.

They shipped the 128k model as the first model.

Because August was historically Vegas's off-season, being a bajillion and a half degrees outside, and they could get a good deal on conference space.

It's not BCD style magic, but just a choice of units. Say instead of in meters, if the unit is 1/65536 of a meter, than you can describe those integers as 16.16 fixed point meters.

I'm not sure if it's useful in this incarnation, but I am reminded of the localizers in A Deepness in the Sky, an early description of smartdust which were relatively omnipresent and capable of communicating and being reprogrammed

This dockerfile explicitly enables kvm in a way that will cause qemu to fail if it's not present.
827.
by monocasa 2y ago
This requires kvm exposed in the container. Does docker on mac support kvm?

That's just the architecture and driver independent part of the kernel. The kernel source tree is 15M lines or so.

The oxidation is. The choice of voltage scaling is not.

I didn't imply that the code remains and it's only data that is swapped out. The thread jumps to another complete address space. It's like a system call instruction that instead of jumping into the kernel, jumps into another

Writing a top level comment here to hopefully address some of the misconceptions present across this comment section. Doors at the end of the day aren't message passing based RPC. There is no door_recv(2) syscall or equivalent nor any
832.
by monocasa 2y ago
Not quite. There isn't a door_recv(2) systemcall or equivalent. Doors truly don't transfer messages, they transfer the thread itself. As in the thread that made a door call is now just directly executing in the address space of t

It's a remote console to the management engine for "lights out management" or remotely being able to to what a hardware tech would generally need physical access for like accessing the preboot environment. It's bad if yo

At this point I'm a bit surprised that nobody has created a netlist of the board and simply reinstalled the relevant chips on it. There has to be more density that can be eked out for easier that way than carefully taking a Dremel to

Thanks for catching that.

When you can't verify an update, rolling back atomically to the previous state is generally considered the safest option. Best run what you can verify was a complete package from whoever you trust.

Kernel driver bug that essentially defaults, then on reboot loads the same driver early on segfaults and reboots again, ad nauseum.

Nothing like that, basically what sitharus said above you. Extra network level, zero trust to minimize lateral movement and giving the pen testers a leg up by letting them start already within the corporate network.

The contracts are rarely specifying stuff like antivirus explicitly, but instead compliance with one or more of the security standards like PCI DSS. Those say you have to use antivirus, but they all have an escape hatch called a "comp
