Does inconsistency count as Byzantine failure? Posted: 28 Dec 2019 04:08 PM PST I have difficulty understand Section 18.3 Fault Tolerance Services under Ch18 Replication in Coulouris' Distributed Systems. If my reading and understanding is correct (which might not), Section 18.3.1 Passive Replication describes services that have linearizability consistency but don't tolerate Byzantine failures. Section 18.3.2 Active Replication describes services that have weak (sequential) consistency but tolerate Byzantine failures. In a distributed systems with data replication, does stale data i.e. data inconsistency due to weak level of consistency count as Byzantine failure? (Seems to me yes, but my reading above seems no.) When a distributed system with replication is said to tolerate Byzantine failures, does it necessarily have the strict level of consistency, i.e. linearizability? (Seems to me yes, but my reading above seems no.) Thanks. submitted by /u/timlee126 [link] [comments]

Turing machine question Posted: 28 Dec 2019 12:51 PM PST I have to program a turing machine that decrements a number until it reaches 0 Now lets say n is a byte Is it legit for a turing machine to state the start config such as the tape at start is n#n ? Where # is the blank? Or to take the first step for every read symbol to replace it with # and decrement the second n? submitted by /u/Rapiz [link] [comments]

What subfields to do a phd in if I want to work in the industry afterwards? Posted: 28 Dec 2019 06:55 AM PST I know phds are generally bad if one wants to work in the industry (in terms of opportunity costs), but barring that, what subfields are the best? Views from around the world will be appreciated. submitted by /u/whats-a-monad [link] [comments]
