There is some evidence to suggest that spacex knows how to reenter an object without burning it up.

Possibly, although that article seems quite confused as well (of course they need custom silicon, and of course that doesn't mean anything about what COTS parts they do or don't use). It would be nice if SpaceX would publish more

SpaceX supposedly mostly runs non-rad-hard parts, the ostensible reason being because its more cost effective to double or triple up than buy specialty equipment. Do you have a source for this?

How is this different from slushomatics? Sounds exactly like old school fluid couplings.

Anecdotally, a lot more people in the US tow. And pickup trucks are the indisputable king of towing. There's also the fact that it's a lot harder to take the top off a van than it is to add a top to the bed of a pickup. If I somet

The biggest thing I learned from PE was that neither elegant theory nor brute force had a monopoly on successful optimization strategies. It's been something I've carried with me ever since and has over and over again proven its v

My politics and his don't line up but I'm not against this. It would be pretty interesting to see the impact on cash usage, and faces on money are pretty archeologically useful-- at least on coins.

Isn't this basically just putting the kid in a tumble drier whenever you hit turbulence? Did they pad the roof and door as well?

I think there's something to what the author says about the shift from mission-driven startups to naked greed, but I don't think I would have put it that way. Over the last two decades the startup scene has gone from trying to imp

None of these snippets appear to involve eBPF at all?

The point of what I spelled out above is that they can jump to the instruction but the kernel will kill the program if they don't go through the function up to that point. That allows you to restrict the arguments to the syscall at the

"Attacker has ROP and shouldn't be able to make arbitrary syscalls". Seems mildly useful if you have a really flexible syscall you can't forbid (ioctl, say) but which you only use for a specific narrow purpose.
46.
by debatem1 2y ago
Seems like an interesting if maybe not practical protection to implement in eBPF for programs that never make a naked syscall. Step one would be to ensure that every syscall has a wrapper. Place a uprobe at the start of that wrapper which,

I don't think anyone ever doubted that a C program could be memory safe. The problem is knowing without exhaustive work whether yours is one of them. These aren't bad practices, but I don't think they satisfy that desire eith

I don't know if it was deliberate, but writing code that interfaces with GDB is unpleasant enough that I opted to build our debugger-like tooling in eBPF + pyelftools instead.

Custom forms for concrete pours. Also did a little bit of work making supports for plaster casting. I was never really able to sell the advantages to artists, but got some good side gig money for landscaping stuff. (Just to clarify: the bus

ASAN doesn't mask bugs-- quite the opposite, it turns silent memory corruptions into crashes.
