This also used to be the case in Poland. Now you can choose the GP you go to and change that decision IIRC twice a year. Choosing a doctor that's far away makes no sense, so there's no or little reason to restrict that choice to c

Interesting case: Poland has an address register that is slowly being deprecated -- it is no longer necessary to ever update it and in increasingly fewer situations a record from that registry is required (and it would be very unpopular if

Note that this is already happening. The only thing my proposal would change is that it would also affect servers that used to be authoritative for subdomains of such abandoned domains. I would expect there to be very few of them: very few

If a server goes away for good, at some point NS records will stop pointing to it. We could serve stale records as long as all of the stale record's authority chain is either still there or unreachable.

This just requires the inability-to-rewind property of the blockchain, doesn't require there to be one centralized log of events and doesn't require protections against flooding with data (if we verify that the DNS records are cor

Have a self-signed CA certificate with a longish expiration and sign the actual keys the webservers use with that. Apply TOFU to that CA certificate (on a per-domain basis). There's IIRC no mechanism for that, but for the single-domain

Why is it worse than sending a separate packet to each of the participants? If we're using multicast router can send packets to all participants in any order (when links become available) while storing one copy of it. If we're sen

I would like to learn of examples when would this be useful. My layman's understanding is as follows: If we're searching for something that we don't know an approximate location of, depriving everyone around of night vision,

I expect a drone with a low light and/or thermal camera to be immensely more useful for SAR.

You assume that the binary you are using is one those people have already seen. This need not be the case: a rollout might have started hours ago and you might have been one of the first few to get the new version.

Do you mean "we expect people not to have an illusion of security" or "we would want people not to have an illusion of security"? I posit that this actually creates an illusion that http is better than "insecure&quo

It baffles me why do all browsers pretend that https with an untrusted certificate is worse than plain http.

Note that the problem with those Notes might've been caused not by the battery, but by the battery's environment (mechanical, thermal or electrical).

Then you could just as well bring a crowbar and throw it at something to cause a short. Or just smash stuff manually. This device has a very small range.

IIRC TESTSET is usable: IIRC it just sends a message that causes that to happen, but you don't learn if the test succeeded. I was talking about the DMA mode in which every write to special register (that may be coming from a different

by robryk 10y ago
If you're looking for weird synchronization primitives, look at the documentation of the DMA controller. It has a mode in which it stores bytes that are written to a particular address in a memory range in order the writes arrive. I ha

by robryk 10y ago
The easiest way to think about it is that remote access is order-preserving message passing with a separate message network for reads (as it truly is), so: 0. Local reads and writes happen immediately. 1. Writes from core X to core Y are co

"using intrinsics" is a cop out: you are essentially doing the more complicated part of translating that sequence of generic C code into a rough approximation of a sequence of machine instructions and leave the compiler to do the

The chief programmer of both Apollo guidance computers was Margaret Hamilton. The computer had only non-volatile memory. Upon restart it would clean some parts of it up, but most of what the user would think of as the state would remain. No

Why is the severity of the first vulnerability high? It allows a denial of service on the server's side by a client and nothing else. The second vulnerability seems to be very similar in severity, except that it can be used both agains

Why can't you attach a serial console? This will help with any problems that still let you get to grub (BIOS Setup likely doesn't support UI over serial, unless it's a server-like machine). Once you have a serial console, you
