three weeks ago meteor projects worked fine, today noticed all meteor projects skip 'start-mongodb' step , or @ least seems way. projects rely on 1 or more collections stuck on 'starting app' step, while new projects start (probably because no mongodb doesn't cause problems them). note: i'm having these problems while running applications locally on laptop. most posts can find apps freezing on 'starting app' mention app can't connect mongodb, relates case, because never started, i don't know how tell meteor should start mongodb first before running of apps . any tips on matter? have set environment variable mongo_url ? if so, meteor (aka meteor run ) not start mongodb.

i'm using python-igraph extract subgraph non-directed graph. nodes locations, , subgraph represents nodes/edges within radius node. i need find weights connect outside nodes of subgraph main graph, there simple way of doing this? i'm not sure of formally called. this total weight of cut between chosen set of nodes , rest of graph. can try this: your_nodes = [1, 2, 3] other_nodes = sorted(set(range(graph.vcount())) - set(your_nodes)) weight_of_cut = sum(graph.es.select(_between=(your_nodes, other_nodes))["weight"])
