If you are using Raft for replication, at any given time your replica set has a leader and it is located somewhere, and I would assume that writes from near there are faster than from anywhere else. In FoundationDB this is handled at a som

FoundationDB has long supported both synchronous and asynchronous replication across regions, and its major users use multi-regional configurations. In the former mode, you will see 1xRTT latency for commits [1] from the active datacente

I think the future defense against this sort of thing is more situational awareness on the part of the phone. You won't just have to fool the biometrics, you'll have to do so without making the phone suspicious at any point. My gu

If someone you know has had bladeless laser eye surgery (with a "femtosecond" pulse laser), it probably used chirped pulse amplification.

FoundationDB uses a consensus algorithm for reconfiguration, but not in the (happy path) transaction pipeline. It provides (by default) strict serializability (i.e. serializability and external consistency/linearizability) for arbitrar

This article lacks any reference to FoundationDB, which offers external consistency and serializable distributed transactions without trusting clocks in any way. We designed it starting in 2009 and so its lineage is independent of either Ca

In my admittedly very cursory skim of the paper, I gave it the benefit of the doubt on this point, because this seemed convincing: "for the purpose of prediction, we are, of course, not so much interested in the probabilities issued by

The argument of this very long and technical paper seems to boil down to this: Solomonoff induction is (in the limit) as good as any computable prediction method, which sounds pretty "universal". But it is not itself a computable

I don't think the problem is federation. The problem is media where participants have nothing at stake, so that abusers can't be made to pay the costs of their abuse. Changing this isn't incompatible with anonymity - for exam

Not all kinds of query plans can be expressed as nested loops, though. Index intersections and other ordered merge operations are very useful, and how do you do them with only nested loop plans?

I said "not speculatively executing AVX-512 instructions _when the units are powered down_".

by voidmain 8y ago
Powering up the full AVX-512 datapath supposedly takes something like 500 microseconds, and then slows the clock speed for something like 2000 microseconds. If so, you could literally just make every AVX-512 instruction fault when the un

On the AVX thing, I think maybe you can eliminate it as a channel for speculative execution attacks by just not speculatively executing AVX-512 instructions when the units are powered down, which also sounds more efficient (it doesn&#x2

We need a certificate transparency type solution that makes pushing compromised firmware to individual devices impractical. That still leaves forcing manufacturers to insert backdoors in all devices, which as far as I know can only be made
