How is 'idempotent' pronounced?
idempotent has two widely accepted pronunciations: /ˌaɪdɛmˈpoʊtənt/ — 'eye-dem-POH-tunt' (the more common form, stress on 'POH') and /ɪˈdɛmpətənt/ — 'ih-DEM-puh-tunt' (stress on 'DEM'). Both are correct. The word (from 'idem' = same + 'potent' = power) describes an operation that produces the same result no matter how many times it is applied. In distributed systems, idempotent operations are safe to retry: \'Make the PUT handler eye-dem-POH-tunt so retries are safe\'.

How is 'quorum' pronounced?
quorum is pronounced /ˈkwɔːrəm/ — 'KWOR-um'. 'Quo' = /kwɔː/ (the /kw/ cluster + long /ɔː/ as in 'four'). '-rum' = /rəm/ (schwa). Two syllables: KWOR-um, stress on the first. Non-native speakers may try to spell out the 'Q' or stress the second syllable. A quorum is the minimum number of nodes that must agree for a distributed operation to succeed, central to consensus algorithms: \'A write needs a KWOR-um of replicas to acknowledge\'.
3 / 5
How is 'Paxos' pronounced?
Paxos is pronounced /ˈpæksɒs/ — 'PAK-soss'. It is named after the Greek island of Paxos. 'Pak' = /pæk/ (short /æ/ as in 'pack'). '-sos' = /sɒs/ (short /ɒ/). Two syllables: PAK-soss, stress on the first. Non-native speakers may use diphthongs or a long 'a'. Paxos is a family of protocols for solving consensus in a network of unreliable processors, foundational to fault-tolerant distributed systems: \'The cluster reaches agreement using a PAK-soss-based algorithm\'.

How is 'Raft' (the consensus algorithm) pronounced?
Raft is pronounced /rɑːft/ (British) or /ræft/ (American) — 'RAHFT' / 'RAFT', exactly like the English word for a floating platform, rhyming with 'craft'. Single syllable. The vowel is the long /ɑː/ or short /æ/ depending on accent, followed by /ft/. It is a word, not an acronym (though it loosely evokes 'Reliable, Replicated, Redundant, And Fault-Tolerant'). Raft is a consensus algorithm designed to be more understandable than Paxos, used in etcd and Consul: \'Leader election is handled by the RAFT protocol\'.

How is 'gossip' (gossip protocol) pronounced?
gossip is pronounced /ˈɡɒsɪp/ — 'GOS-ip', exactly like the English word for casual rumour-spreading. 'Gos' = /ɡɒs/ (short /ɒ/ as in 'boss'). '-sip' = /sɪp/ (short /ɪ/). Two syllables: GOS-ip, stress on the first. Non-native speakers may use a diphthong ('GOH-sip') or stress the second syllable. A gossip protocol is a peer-to-peer communication style where nodes periodically exchange state with random peers, spreading information epidemically: \'Cluster membership propagates via a GOS-ip protocol\'.
